endometriosis,  anxiety,  depression,  pain,  diabetes,  benign  prostatic  hyperplasia  (BPH),  irritable  bowel 
syndrome (IBS) and other neurological and endocrine related diseases and disorders.

Dear Shareholders,

Just over a year ago we began reshaping Neurocrine into a leaner organization focused on creating novel

and important new therapies. In this brief period a new Neurocrine is beginning to emerge; with three
programs in Phase II development, a novel treatment for movement disorders poised to enter the clinic,
multiple earlier stage discovery and research efforts in neurological and endocrine based diseases and
disorders, supported by a strong balance sheet.

ELAGOLIX

Elagolix, our orally active Gonadotropin-Releasing Hormone (GnRH) antagonist compound for the
treatment of endometriosis, has been making significant progress in the clinic with three ongoing Phase IIb
trials. During 2008 the drug met its endpoints in the Petal Study, our first Phase IIb clinical trial, an
assessment of the impact of elagolix on bone mineral density. The results of this 252 person study
demonstrated that elagolix had minimal impact on bone mineral density at the conclusion of the six months of
treatment. Additionally, secondary endpoints were evaluated that showed both a statistical and clinically
meaningful reduction in endometriosis symptoms. Following the success of this study, we reported on the
results of our second study, Lilac Petal, a placebo controlled Phase IIb study designed to more fully explore
the dose range and evaluate several exploratory endpoints. The top-line results of this study were reported in
March of 2009 and elagolix was shown to be very well tolerated by patients and efficacious in treating the
predominant painful symptoms of endometriosis. This trial will continue treating the patients for an additional
three months and we will report the full data set in mid-summer of this year. Our third ongoing Phase IIb
study, Tulip Petal, is being conducted in Central Eastern Europe. We expect the results from this study to be
available in early fourth quarter of 2009. With the conclusion of these trials we will request an end of Phase II
meeting with the FDA at the end of this year.

The GnRH program is broad based with a number of potential indications in both women’s health and

men’s health. We have several back-up compounds and follow-on compounds behind elagolix. We have
created an extensive patent estate covering composition of matter, formulation, manufacturing and methods of
use. Several of these patents are now issued and we anticipate upon approval elagolix will have 14 years of
patent protection, the maximum patent term allowable.

CRF1

Our Corticotropin-Releasing Factor Receptor 1 Antagonist (CRF) collaboration with GlaxoSmithKline

(GSK) is maturing. GSK completed two Phase II studies this past year with compound 876008 for social
anxiety and irritable bowel syndrome (IBS). While we were disappointed with the results of these trials, GSK
remains committed to the CRF program as evidenced by the advancing of a second lead compound, 561679,
into a Phase II major depression study. This study is designed to assess safety and efficacy of this compound
in approximately 150 subjects with Major Depressive Disorder. We anticipate reporting the results of this study
in the second half of 2010. GSK has also moved another compound, 586529, into Phase I development with a
successful single escalating dose trial in 2008.

UROCORTIN 2

Congestive heart failure is a condition where the heart muscle is weakened and cannot pump enough
blood to supply all the organs in the body. Urocortin 2, an endogenous peptide ligand of the CRF2 receptor, is
abundantly expressed in the cardiovascular system, most notably the heart and cerebral arterial system.
Urocortin 2 and its receptor have been shown to have an array of effects on the cardiovascular system and
metabolism. Early on we completed two Phase IIa studies which demonstrated positive hemodynamic effects
in virtually all patients without serious adverse events, abnormalities in electrocardiograms or significant
changes in renal function. This past year we were tasked with completing the necessary preclinical toxicology
work to allow for periods of infusion of urocortin 2 up to 14 days. This toxicology work has been successfully
completed, essentially fulfilling the required FDA preclinical package and allowing for further clinical
development of this peptide.

We will be collaborating with the Christchurch Cardioendocrine Research Group at the Christchurch
School of Medicine and Health Sciences in New Zealand on a study of Urocortin 2 in the treatment of 50

Acute Decompensated Heart Failure patients. Recruitment for this should begin in 2009 pending final approval
by the various regulatory oversight bodies.

VMAT 2

We look forward to moving a new small molecule compound into human clinical trials this year.
Vesicular Monoamine Transporter 2 (VMAT2) is a protein concentrated in the brain that is essential for the
transmission of nerve impulses between neurons. Neurocrine research and discovery efforts have identified a
highly selective VMAT2 inhibitor that is effective in regulating the levels of dopamine release during nerve
communication, while at the same time reducing the likelihood of “off target” side effects. This compound
will move into Phase I clinical trials in 2009 and we believe will be effective in the management of
hyperkinetic movement disorders characterized by involuntary bodily movements such as tardive dyskinesia
and Huntington’s disease.

RESEARCH

Our research scientists are focusing their efforts on diseases and disorders of the central nervous and

endocrine systems. We are also focusing our efforts on novel targets in pain, metabolic diseases, and
anticonvulsants for the treatment of epileptic seizures as well as ongoing research with our GnRH antagonists
to further develop additional candidates for preclinical and clinical studies.

In the face of the current worldwide economic crisis, we have been rigorously establishing R&D
priorities, and diligently monitoring our operating costs and managing our cash. Because of this prudent and
cautious planning, Neurocrine has been able to meet both our scientific and financial goals for 2008. We are
poised for the future with a strong balance sheet and strong pipeline.

With new leadership comes change and this past year exemplified those changes as a new Neurocrine
begins to come into view. Each year brings new challenges and tough decisions that have to be made. We will
continue to address those challenges while continuing to enhance shareholder value. I want to thank you, our
shareholders, for your continued support as we weather this economic storm. I’d also like to thank our
employees for their hard work and dedication to our Company.

PROXY STATEMENT

The enclosed Proxy is solicited on behalf of Neurocrine Biosciences, Inc., a Delaware corporation (the
“Company”), for use at its 2009 Annual Meeting of Stockholders to be held on May 29, 2009 beginning at
8:30 a.m., local time, or at any continuations, postponements or adjournments thereof for the purposes set
forth in this Proxy Statement and the accompanying Notice of Annual Meeting of Stockholders. The Annual
Meeting will be held at the Company’s corporate headquarters, located at 12780 El Camino Real, San Diego,
California 92130. The Company’s phone number is (858) 617-7600.

This proxy statement is being first mailed on or about April 21, 2009 to all stockholders entitled to vote

at the Annual Meeting.

ABOUT THE ANNUAL MEETING

What is the purpose of the Annual Meeting?

At our Annual Meeting, stockholders will act upon the matters outlined in the Notice of Annual Meeting

of Stockholders on the cover page of this proxy statement, including the election of the three nominees for
director named herein, ratification of the appointment of Ernst & Young LLP as the Company’s independent
registered public accounting firm for the fiscal year ending December 31, 2009, approval of an amendment
increasing the number of shares of common stock reserved for issuance under the Company’s 2003 Incentive
Stock Plan, as amended (the “2003 Plan”) from 5,300,000 to 5,800,000, and consideration of a stockholder
proposal to declassify the Board of Directors. In addition, management will report on the performance of the
Company and respond to questions from stockholders.

Who can attend the Annual Meeting?

All stockholders of record at the close of business on April 1, 2009 (the “Record Date”), or their duly
appointed proxies, may attend the Annual Meeting. If you attend, please note that you may be asked to present
valid picture identification, such as a driver’s license or passport. Cameras, recording devices and other
electronic devices will not be permitted at the Annual Meeting.

Please also note that if you hold your shares in “street name” (that is, through a broker or other nominee),

you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date
and check in at the registration desk at the Annual Meeting.

Who is entitled to vote at the Annual Meeting?

Stockholders of record at the close of business on the Record Date are entitled to receive notice of and to

participate in the Annual Meeting. At the close of business on the Record Date, 38,677,454 shares of the
Company’s common stock, $0.001 par value per share, were issued and outstanding. If you were a stockholder
of record on that date, you will be entitled to vote all of the shares that you held on that date at the Annual
Meeting, or any postponements or adjournments of the Annual Meeting.

Each outstanding share of the Company’s common stock will be entitled to one vote on each proposal

considered at the Annual Meeting.

What constitutes a quorum?

The presence at the Annual Meeting, in person or by proxy, of the holders of a majority of the aggregate

voting power of the common stock outstanding on the Record Date will constitute a quorum, permitting the

Company to conduct its business at the Annual Meeting. As of the Record Date, 38,677,454 shares of common
stock, representing the same number of votes, were outstanding. Thus, the presence of the holders of common
stock representing at least 19,338,728 shares will be required to establish a quorum. The presence of a quorum
will be determined by the Inspector of Elections (the “Inspector”).

Proxies received but marked as abstentions as well as “broker non-votes” will be included in the
calculation of the number of shares considered to be present at the Annual Meeting. Broker non-votes occur
when a holder of shares in “street name” does not give instructions to the broker or nominee holding the
shares as to how to vote on matters deemed “non-routine” under applicable regulations.

How do I vote?

If you complete and properly sign the accompanying proxy card and return it to the Company, it will be

voted as you direct. If you are a registered stockholder (that is, if you hold your stock in certificate form or
are a Neurocrine employee who participated in the Employee Stock Purchase Program and attend the Annual
Meeting), you may deliver your completed proxy card in person. “Street name” stockholders who wish to vote
at the Annual Meeting will need to obtain a proxy form from the institution that holds their shares.

The cost of solicitation of proxies will be borne by the Company. The Company will reimburse expenses

incurred by brokerage firms and other persons representing beneficial owners of shares in forwarding
solicitation material to beneficial owners. To assist in soliciting proxies (votes), the Company may retain
Innisfree, a professional proxy solicitation firm, at an approximate cost of $10,000, plus certain out-of-pocket
expenses. Proxies also may be solicited by certain of the Company’s directors, officers and regular employees,
without additional compensation, personally, by telephone or by other appropriate means.

Can I vote by telephone or electronically?

If you are a registered stockholder you may vote by telephone, or electronically through the Internet, by

following the instructions included with your proxy card. If your shares are held in “street name,” please check
your proxy card or contact your broker or nominee to determine whether you will be able to vote by telephone
or electronically. The deadline for voting by telephone or electronically is 11:59 p.m., Eastern Time, on
May 28, 2009.

Can I change my vote after I return my proxy card?

Yes. Even after you have submitted your proxy, you may change your vote at any time before the proxy

is exercised by filing with the Corporate Secretary of the Company either a notice of revocation or a duly
executed proxy bearing a later date. Your proxy will also be revoked if you attend the Annual Meeting and
vote in person. Attendance at the Annual Meeting will not by itself revoke a previously granted proxy.

What are the Board’s recommendations?

Unless you give other instructions on your proxy card, the persons named as proxy holders on the proxy
card will vote in accordance with the recommendations of the Board of Directors. The Board’s recommenda-
tion is set forth together with the description of each item in this proxy statement. In summary, the Board
recommends a vote:

(cid:129)

(cid:129)

(cid:129)

for election of the three nominees for director named herein (see Proposal One);

for ratification of the appointment of Ernst & Young LLP as the Company’s independent registered
public accounting firm for fiscal 2009 (see Proposal Two);

for approval of the amendment to the Company’s 2003 Incentive Stock Plan, as amended, to increase
the number of shares of common stock reserved for issuance thereunder from 5,300,000 to 5,800,000
(see Proposal Three); and

(cid:129)

With respect to any other matter that properly comes before the meeting, the proxy holders will vote as

recommended by the Board of Directors or, if no recommendation is given, in their own discretion.

What vote is required to approve each item?

Election of Directors. The affirmative vote of a plurality of the votes cast at the Annual Meeting is
required for the election of directors. A properly executed proxy marked “WITHHOLD AUTHORITY” with
respect to the election of one or more directors will not be voted with respect to the director or directors
indicated, although it will be counted for purposes of determining whether there is a quorum.

Other Items. For each other item, the affirmative vote of the holders of a majority of the shares
represented in person or by proxy and entitled to vote on the item will be required for approval. A properly
executed proxy marked “ABSTAIN” with respect to any such matter will not be voted, although it will be
counted for purposes of determining the number of shares represented in person or by proxy at the Annual
Meeting. Accordingly, an abstention will have the effect of a negative vote.

If you hold your shares in “street name” through a broker or other nominee, your broker or nominee may

not be permitted to exercise voting discretion with respect to some of the matters to be acted upon. Thus, if
you do not give your broker or nominee specific instructions, your shares may not be voted on and will not be
counted in determining the number of shares represented in person or by proxy at the Annual Meeting. Shares
represented by such “broker non-votes” will, however, be counted in determining whether there is a quorum.

Who counts the votes?

Votes cast by proxy or in person at the Annual Meeting will be tabulated by the Inspector.

What proxy materials are available on the Internet?

The proxy statement and annual report to stockholders are available on the Internet at www.proxyvote.-

com. Please have the control number on your proxy card available.

(3) Shares of common stock subject to stock options currently exercisable or exercisable within 60 days of
February 28, 2009, regardless of exercise price, and shares of common stock acquirable within such
period pursuant to restricted stock awards, are deemed to be outstanding for computing the percentage
ownership of the person holding such options and the percentage ownership of any group of which the
holder is a member, but are not deemed outstanding for computing the percentage of any other person.

(4) Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commis-
sion and generally includes voting or investment power with respect to securities. Except as indicated by
footnote, and subject to community property laws where applicable, the persons named in the table have
sole voting and investment power with respect to all shares of common stock shown as beneficially
owned by them.

(5) Based on Amendment No. 3 to Schedule 13G filed by Biotechnology Value Fund, L.P. (“BVF”), Biotech-
nology Value Fund II, L.P. (“BVF2”), BVF Investments, L.L.C. (“BVLLC”), Investment 10, L.L.C.

cially owed by BVLLC and to vote and exercise dispositive power over those shares of the Common
Stock. Partners and BVF Inc. share voting and dispositive power over shares of the Common Stock bene-
ficially owned by BVF, BVF2, BVLLC and those owned by ILL10, on whose behalf Partners acts as an
investment manager, and, accordingly, Partners and BVF Inc. have beneficial ownership of all of the

(6) Based on Amendment No. 3 to Schedule 13G filed by Federated Investors, Inc. (“Federated”) on

February 17, 2009, reporting ownership as of December 31, 2008. According to such filing, Federated is
the parent holding company of Federated Equity Management Company of Pennsylvania and Federated
Global Investment Management Corp. (the “Investment Advisers”), which act as investment advisers to
registered investment companies and separate accounts that own shares of common stock in the Company
(the “Reported Securities”). The Investment Advisers are wholly owned subsidiaries of FII Holdings,
Inc., which is a wholly owned subsidiary of Federated. All of Federated’s outstanding voting stock is held
in the Voting Shares Irrevocable Trust (the “Trust”) for which John F. Donahue, Rhodora J. Donahue and
J. Christopher Donahue act as trustees (collectively, the “Trustees”). The Trustees have joined in filing
the Schedule 13G because of the collective voting control that they exercise over Federated. Federated,
the Trust, and each of the Trustees disclaim beneficial ownership of the Reported Securities.

(7) Based on Schedule 13G dated February 5, 2009 reporting ownership as of December 31, 2008, filed

jointly by Barclays Global Investors, NA., Barclays Global Fund Advisors, Barclays Global Investors,
LTD, Barclays Global Investors Japan Limited, Barclays Global Investors Canada Limited, Barclays

1,159,784 shares and sole dispositive power as to 1,159,784 shares.

(8) Based on Schedule 13G filed by Dimensional Fund Advisors LP (“Dimensional”) on February 9, 2009,
reporting ownership as of December 31, 2008. According to such filing, Dimensional is an investment
advisor registered under Section 203 of the Investment Advisors Act of 1940, furnishes investment advice
to four investment companies registered under the Investment Company Act of 1940, and serves as
investment manager to certain other commingled group trusts and separate accounts. These investment
companies, trusts and accounts are the “Funds”. In its role as investment advisor or manager, Dimen-
sional possesses investment and/or voting power over the securities of the Company described in this
schedule that are owned by the Funds, and may be deemed to be the beneficial owner of the shares of

5

the Company held by the Funds. However, all securities reported in this schedule are owned by the
Funds. Dimensional disclaims beneficial ownership of such securities.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the
Company’s officers and directors, and persons who beneficially own more than ten percent of a registered
class of the Company’s equity securities, to file reports of ownership on Form 3 and reports of changes in
ownership on Form 4 or Form 5 with the SEC. Such officers, directors and 10% stockholders are also required
by SEC rules to furnish the Company with copies of all Section 16(a) forms they file. Based solely on its
review of the copies of such forms received by it, and written representations from certain reporting persons,
the Company believes that its officers, directors and 10% stockholders complied with all Section 16(a) filing
requirements applicable to them during the fiscal year ended December 31, 2008.

PROPOSAL ONE: ELECTION OF DIRECTORS

General

The Company’s Bylaws provide that the Board of Directors will be comprised of eight directors. The

Company’s Certificate of Incorporation provides that the Board of Directors is divided into three classes.
There are currently three directors in Class I (Joseph A. Mollica, Ph.D., Wylie W. Vale, Ph.D. and W. Thomas
Mitchell), three directors in Class II (Corinne H. Lyle, Richard F. Pops, and Stephen A. Sherwin, M.D.), and
two directors in Class III (Gary A. Lyons and Kevin C. Gorman, Ph.D.). With the exception of Kevin C.
Gorman, Ph.D., who is the President and Chief Executive Officer of Neurocrine Biosciences, Inc., and Gary
A. Lyons, who is the former President and Chief Executive Officer of Neurocrine Biosciences, Inc. all current
members of the Board of Directors meet the definition of “independent director” under the Nasdaq Stock
Market qualification standards.

The directors in Class I hold office until the 2009 Annual Meeting of Stockholders, the directors in
Class II hold office until the 2010 Annual Meeting of Stockholders and the directors in Class III hold office
until the 2011 Annual Meeting of Stockholders (or, in each case, until their earlier resignation, removal from
office, or death). After each such election, the directors in each such case will then serve in succeeding terms
of three years and until a successor is duly elected and qualified. Officers of the Company serve at the
discretion of the Board of Directors. There are no family relationships among the Company’s directors and
executive officers.

The term of office for directors Joseph A. Mollica, Ph.D., Wylie W. Vale, Ph.D. and W. Thomas Mitchell,
will expire at the 2009 Annual Meeting. At the 2009 Annual Meeting, the stockholders will elect three Class I
directors for a term of three years.

Vote Required

The nominees receiving the highest number of affirmative votes of the shares present in person or
represented by proxy at the 2009 Annual Meeting and entitled to vote on the election of directors will be
elected to the Board of Directors.

Votes withheld from any director are counted for purposes of determining the presence or absence of a

quorum, but have no other legal effect under Delaware law.

Unless otherwise instructed, the proxy holders will vote the proxies received by them for the Company’s
nominees named below. If any of the Company’s nominees is unable or declines to serve as a director at the
time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the present Board
of Directors to fill the vacancy. It is not expected that any of the Company’s nominees will be unable or will
decline to serve as a director. The Board of Directors unanimously recommends that stockholders vote
“FOR” the nominees named below.

How often did the Board meet during fiscal 2008?

The Board of Directors of the Company held a total of nine meetings during 2008. During 2008, the

Board of Directors had an Audit Committee, a Compensation Committee and a Nominating/Corporate
Governance Committee. Charters for each of these committees have been established and approved by the
Board of Directors and copies of the charters of the Audit and Compensation Committees have been posted on
the Company’s website at www.neurocrine.com. During 2008, no director attended fewer than 75% of the
aggregate of the total number of meetings of the Board of Directors and the total number of meetings held by
all committees of the Board of Directors on which such director served.

What are the various committees of the Board and which directors are on those committees?

The Company’s Audit Committee is comprised entirely of directors who meet the independence
requirements set forth in Nasdaq Stock Market Rule 4350(d)(2)(A). Information regarding the functions
performed by the committee, its membership, and the number of meetings held during the fiscal year is set
forth in the “Report of the Audit Committee,” included in this annual proxy statement. The current members
of the audit committee are Corinne H. Lyle, Richard F. Pops, and W. Thomas Mitchell. The Board of Directors
has determined that Corinne H. Lyle and Richard F. Pops are “audit committee financial experts” within the
meaning of item 407(d)(5) of SEC Regulation S-K.

During 2008, the Compensation Committee consisted of directors Richard F. Pops, Stephen A. Sherwin, M.D.

and Wylie W. Vale, who became a member of the Compensation Committee in February 2008. This committee
met three times during 2008. The Compensation Committee reviews and recommends to the Board the
compensation of executive officers and other employees of the Company. Each of the current members of the
Compensation Committee is an independent director as defined by Nasdaq Stock Market Rule 4200(a)(15).

The Company also has a Nominating/Corporate Governance Committee currently comprised of

W. Thomas Mitchell, Joseph A. Mollica, Ph.D. and Stephen A. Sherwin, M.D; all of whom are independent
directors as defined by Nasdaq Stock Market Rule 4200(a)(15). The Nominating/Corporate Governance
Committee is responsible for developing and implementing policies and practices relating to corporate
governance, including administration of the Company’s Code of Business Conduct and Ethics which is

9

available on the Company’s website at www.neurocrine.com. The functions of this committee also include
consideration of the composition of the Board and recommendation of individuals for election as directors of
the Company. The Nominating/Corporate Governance Committee will consider nominees recommended by
stockholders provided such nominations are made pursuant to the Company’s Bylaws and applicable law. The
committee met once during 2008 to recommend the slate of directors that was approved at the 2008 Annual
Meeting of Stockholders. The committee met in early 2009 to recommend that the Board of Directors
nominate Joseph A. Mollica, Ph.D., Wylie W. Vale, Ph.D. and W. Thomas Mitchell for re-election as Class I
directors for the upcoming three-year term.

What is our director nomination process?

Director qualifications

In selecting non-incumbent candidates and reviewing the qualifications of incumbent candidates for the

Board of Directors, the Nominating/Corporate Governance Committee considers the Company’s corporate
governance principles, which include the following:

Directors should possess the highest ethics, integrity and values, and be committed to representing the

long-term interest of the stockholders. They also must have experience they can draw upon to help direct the
business strategies of the Company together with sound judgment. They must be actively engaged in the
pursuit of information relevant to the Company’s business and must constructively engage their fellow Board
members and management in dialogue and the decision-making process.

Directors must be willing to devote sufficient time to carrying out their duties and responsibilities
effectively, and should be committed to serve on the Board for an extended period of time. Directors should
offer their resignation in the event of any significant change in their personal circumstances, including a
change in their principal job responsibilities. In evaluating director nominees, the Nominating/Corporate
Governance Committee considers the following factors: the appropriate size of the Company’s Board of
Directors; personal and professional integrity, ethics and values; experience in corporate management, such as
serving as an officer or former officer of a publicly held company; and experience as a board member of
another publicly held company.

The Nominating/Corporate Governance Committee’s goal is to assemble a Board of Directors that brings

to the Company a variety of perspectives and skills derived from high quality business and professional
experience. In doing so, the Nominating/Corporate Governance Committee also considers candidates with
appropriate non-business backgrounds.

Other than the foregoing, there are no stated minimum criteria for director nominees, although the
Nominating/Corporate Governance Committee may also consider such other facts as it may deem are in the
best interests of the Company and its stockholders. The Nominating/Corporate Governance Committee does,
however, believe that at least one, and, preferably, several, members of the Board of Directors, meet the
criteria for an “audit committee financial expert” as defined by Securities and Exchange Commission rules.
The Nominating/Corporate Governance Committee also believes it appropriate for certain key members of the
Company’s management to participate as members of the Board of Directors.

Identification and evaluation of nominees for directors

The Nominating/Corporate Governance Committee identifies nominees for director by first evaluating the
current members of the Board of Directors willing to continue in service. Current members with qualifications
and skills that are consistent with the Nominating/Corporate Governance Committee’s criteria for Board of
Directors service and who are willing to continue in service are considered for re-nomination, balancing the
value of continuity of service by existing members of the Board of Directors with that of obtaining a new
perspective. If any member of the Board of Directors does not wish to continue in service or if the Board of
Directors decides not to re-nominate a member for re-election, the Nominating/Corporate Governance
Committee identifies the desired skills and experience of a new nominee in light of the criteria above. The
Nominating/Corporate Governance Committee generally polls the Board of Directors and members of

10

management for their recommendations and may also seek input from third-party search firms. The Nominat-
ing/Corporate Governance Committee may also seek input from industry experts or analysts. The Nominating/
Corporate Governance Committee reviews the qualifications, experience and background of the candidates.
Final candidates are then interviewed by the Company’s independent directors and executive management. In
making its determinations, the Nominating/Corporate Governance Committee evaluates each individual in the
context of the Company’s Board of Directors as a whole, with the objective of assembling a group that can
best perpetuate the success of the Company and represent stockholder interests through the exercise of sound
judgment. After review and deliberation of all feedback and data, the Nominating/Corporate Governance
Committee makes its recommendation to the Board of Directors.

We have not received director candidate recommendations from the Company’s stockholders and do not

have a formal policy regarding consideration of such recommendations. However, any recommendations
received from stockholders will be evaluated in the same manner that potential nominees suggested by board
members, management or other parties are evaluated. Accordingly, our Board of Directors believes a formal
policy regarding consideration of such recommendations is unnecessary.

What is our process for stockholder communications with the Board of Directors?

Stockholders of the Company wishing to communicate with the Company’s Board of Directors or an
individual director may send a written communication to the Board of Directors or such director c/o Neurocrine
Biosciences, Inc., 12780 El Camino Real, San Diego, CA 92130, Attn: Corporate Secretary. Each communi-
cation must set forth:

(cid:129)

(cid:129)

the name and address of the Company stockholder on whose behalf the communication is sent; and

the number of Company shares that are owned beneficially by such stockholder as of the date of the
communication.

Each communication will be reviewed by the Company’s Corporate Secretary to determine whether it is
appropriate for presentation to the Board or such director. Examples of inappropriate communications include
advertisements, solicitations or hostile communications.

Communications determined by the Corporate Secretary to be appropriate for presentation to the Board or

such director will be submitted to the Board or such director on a periodic basis.

What is our policy regarding Board member attendance at the Company’s Annual Meeting?

The Company does not have a formal policy regarding attendance by members of the Board of Directors
at the Annual Meeting. Joseph A. Mollica, Ph.D. and Kevin C. Gorman represented the Board of Directors at
the 2008 Annual Meeting of Stockholders.

REPORT OF THE AUDIT COMMITTEE

The following Report of the Audit Committee does not constitute soliciting material and should not be

deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933 or
the Securities Exchange Act of 1934, except to the extent the Company specifically incorporates this Report by
reference therein.

The Audit Committee is currently comprised of directors Corinne H. Lyle, Richard F. Pops, and
W. Thomas Mitchell. All current committee members satisfy the definition of independent director as
established in the Nasdaq Stock Market qualification requirements. The Audit Committee met four times
during the year ended December 31, 2008.

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of
Directors. Management has the primary responsibility for the Company’s financial statements and the reporting
process, including the Company’s systems of internal controls. In fulfilling its oversight responsibilities, the
Audit Committee has reviewed and discussed with management the Company’s audited financial statements as
of and for the year ended December 31, 2008 with management, including a discussion of the quality, not just
the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of
disclosures in the financial statements.

The Audit Committee also has reviewed and discussed the Company’s audited financial statements as of

and for the year ended December 31, 2008 with the Company’s independent registered public accounting firm,
who are responsible for expressing an opinion on the conformity of those audited financial statements with
accounting principles generally accepted in the United States, as well as their judgments as to the quality, not
just the acceptability, of the Company’s accounting principles and such other matters as are required to be
discussed with the Audit Committee under Statement on Auditing Standards No. 114 (The Auditor’s
Communication with Those Charged with Governance), as adopted by the Public Company Accounting
Oversight Board (United States) (the “PCAOB”) in Rule 3200T. The independent registered public accounting
firm also is responsible for performing an independent audit of the Company’s internal control over financial
reporting in accordance with the auditing standards of the PCAOB. In addition, the Audit Committee has
discussed the independent registered public accounting firm’s independence from management and the
Company, including the matters in the written disclosures and the letter from the independent registered public
accounting firm required by applicable requirements of the PCAOB and considered the compatibility of non-
audit services with the auditors’ independence.

The Audit Committee discussed with the Company’s independent registered public accounting firm the
overall scope and plans for their audits. The Audit Committee meets with the independent registered public
accounting firm, with and without management present, to discuss the results of their examinations, their
evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the

Board of Directors that the audited financial statements be included in the Company’s Annual Report on
Form 10-K for the year ended December 31, 2008, for filing with the Securities and Exchange Commission.
The Audit Committee and the Board are also seeking stockholder ratification of the selection of the
Company’s independent registered public accounting firm for the year ending December 31, 2009.

The Audit Committee has considered whether the provision of non-audit services is compatible with
maintaining the independence of Ernst & Young LLP, and has concluded that the provision of such services is
compatible with maintaining the independence of that firm. All of the services rendered by Ernst & Young
LLP were pre-approved by the Audit Committee in accordance with the Audit Committee pre-approval policy
described below.

Audit Committee policy regarding pre-approval of audit and permissible non-audit services of our
independent registered public accounting firm

The Company’s Audit Committee has established a policy that all audit and permissible non-audit

services provided by the Company’s independent registered public accounting firm will be pre-approved by the
Audit Committee. These services may include audit services, audit-related services, tax services and other
services. The Audit Committee considers whether the provision of each non-audit service is compatible with
maintaining the independence of the Company’s registered public accounting firm. Pre-approval is detailed as
to the particular service or category of services and is generally subject to a specific budget. The Company’s
independent registered public accounting firm and management are required to periodically (at least quarterly)
report to the Audit Committee regarding the extent of services provided by the independent registered public
accounting firm in accordance with this pre-approval, and the fees for the services performed to date.

PROPOSAL TWO: RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

General

The Audit Committee has selected Ernst & Young LLP to audit the financial statements of the Company

for the current fiscal year ending December 31, 2009. Ernst & Young LLP has audited the Company’s
financial statements since 1992. Representatives of Ernst & Young LLP are expected to be present at the
Annual Meeting, will have the opportunity to make a statement if they so desire, and are expected to be
available to respond to appropriate questions.

Stockholders are not required to ratify the selection of Ernst & Young LLP as the Company’s independent
registered public accounting firm. However, the Audit Committee is submitting the selection of Ernst & Young
LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify
the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is
ratified, the Audit Committee in their discretion may direct the selection of a different independent registered
public accounting firm at any time during the year if they determine that such a change would be in the best
interests of the Company and its stockholders.

Vote Required

The affirmative vote of the holders of a majority of the shares represented in person or by proxy at the

Annual Meeting will be required to approve and ratify the Audit Committee’s selection of Ernst & Young
LLP. The Board of Directors unanimously recommends voting “FOR” approval and ratification of such
selection. In the event of a negative vote on such ratification, the Audit Committee will reconsider its
selection.

PROPOSAL THREE: APPROVAL OF AN AMENDMENT TO THE 2003
INCENTIVE STOCK PLAN, AS AMENDED

INCREASE OF 500,000 SHARES

General

The 2003 Incentive Stock Plan, as amended, of Neurocrine Biosciences, Inc. (the “2003 Plan”) was
originally approved by the Board of Directors and the stockholders of the Company in 2003. The Board has
approved an increase in the number of shares of common stock reserved for issuance under the 2003 Plan
from 5,300,000 to 5,800,000, subject to stockholder approval at the Annual Meeting.

The Board believes that the proposed increase in the number of shares of common stock reserved for
issuance under the 2003 Plan will allow the Company to attract and retain valuable employees and continue to
provide its employees, consultants and directors with a proprietary interest in the Company. At the Company,
equity awards foster an ownership culture and are a critical tool for driving stockholder value and for
recruiting, retaining and motivating employees. The Company grants annual equity awards to employees as an
incentive to retain its work force and remain competitive. The terms of the Company’s annual equity awards
and the Company’s employee policies are designed to align employee and stockholder interests. The Company
grants equity awards to a broad group of employees and such awards constitute a significant component of the
Company’s employees’ total compensation. The Company’s equity awards contain long-term vesting and
provisions designed to encourage employees to focus on the Company’s long-term goals and success. If our
stockholders do not approve the amendment to the Incentive Stock Plan, the Company strongly believes that it
will be unable to successfully use equity as part of its compensation program, as most of its competitors in the
industry do, putting the Company at a significant disadvantage and compromising its ability to enhance
stockholder value.

14

The 2003 Plan authorizes the grant to our employees of options that qualify as incentive stock options

under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). The 2003 Plan also
authorizes the grant of nonstatutory stock options, restricted stock awards, restricted stock units and stock
bonus awards (collectively “Equity Awards”) to our employees, directors and consultants. The 2003 Plan also
provides that certain nonstatutory stock options will be automatically granted to non-employee directors and
the Chairman of the Board of Directors of the Company, as described below. As of April 1, 2009, under the
2003 Plan there were options outstanding to purchase 2,103,280 shares of common stock, and 1,021,583 shares
were available for future Equity Awards; 14,750 shares were outstanding as part of the Company’s stock bonus
program; 1,364,016 shares were subject to outstanding restricted stock units; and 796,371 shares previously
issued upon exercise of options, restricted stock units and stock bonuses granted under the Plan are now
outstanding shares of common stock. As of April 1, 2009, there were approximately 130 employees and
directors eligible to receive grants under the 2003 Plan. The closing price of the Company’s common stock on
April 1, 2009 was $3.71.

Since the inception of the Company through April 1, 2009, under all equity plans, 14.6 million options
have been granted, 4.4 million option grants have been exercised at a weighted average price of $13.00, and
6.6 million option grants have been cancelled, representing approximately 30%, and 45%, respectively, of the
total options granted since inception of the Company. Additionally, 2.6 million restricted stock units have been
granted of which, 0.9 million have vested and 0.6 million have been cancelled as of April 1, 2009.

Vote Required

At the Annual Meeting, the stockholders are being asked to approve the amendment to the 2003 Plan to

increase the number of shares reserved for issuance thereunder. The affirmative vote of the holders of a
majority of the shares represented in person or by proxy at the Annual Meeting will be required to approve
the amendment of the 2003 Plan. The Board of Directors unanimously recommends voting “FOR” the
approval of the amendment to the 2003 Plan.

Summary of the 2003 Incentive Stock Plan

The essential features of the 2003 Plan are summarized below. This summary does not purport to be

complete and is subject to, and qualified by reference to, all provisions of the 2003 Plan.

General. The purpose of the 2003 Plan is to enable the Company to attract and retain the best available
personnel, to provide additional incentives to the employees, directors and consultants of the Company and to
promote the success of the Company’s business.

Administration. The 2003 Plan is administered by the Board of Directors or a committee appointed by
the Board (the Board or any such committee, the “Administrator”). The 2003 Plan may be administered by
different committees with respect to different groups of employees and consultants. The Administrator may
make any determinations deemed necessary or advisable for the 2003 Plan. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all holders.

Subject to stockholder approval of this Proposal Three, an aggregate of 5,800,000 shares of common
stock is reserved for issuance under the 2003 Plan. Stock subject to the 2003 Plan may be unissued shares or
reacquired shares, bought on the market or otherwise. If any award granted under the 2003 Plan expires or
otherwise becomes unexercisable without being exercised in full, the shares of common stock not acquired
pursuant to such award again become available for issuance under the 2003 Plan.

Eligibility. Nonstatutory stock options, restricted stock awards, restricted stock units and stock bonus
awards may be granted under the 2003 Plan to employees, directors and consultants of the Company and any
parent or subsidiary of the Company. Incentive stock options may be granted only to employees. The
Administrator, in its discretion, selects the employees, directors and consultants to whom awards may be
granted, the time or times at which such awards shall be granted, and the number of shares subject to each
such grant. The 2003 Plan also provides that certain nonstatutory stock options will be automatically granted
to non-employee directors and the Chairman of the Board of Directors of the Company, as described below.

15

Limitations. Sections 162(m) of the Internal Revenue Code places limits on the deductibility for federal
income tax purposes of compensation paid to certain executive officers of the Company. In order to preserve
the Company’s ability to deduct the compensation income associated with awards granted to such persons, the
2003 Plan provides that no employee may be granted, in any fiscal year of the Company, awards covering
more than 250,000 shares of common stock. Notwithstanding this limit, however, in connection with an
employee’s initial employment, he or she may be granted awards covering up to an additional 250,000 shares
of common stock.

Terms and Conditions of Options. Each option is evidenced by a stock option agreement between the

Company and the optionee, and is subject to the following additional terms and conditions:

Exercise Price. The Administrator determines the exercise price of options at the time the options
are granted. The exercise price of a stock option may not be less than 100% of the fair market value of
the common stock on the date such option is granted. In the case of an incentive stock option granted to
an optionee who owns more than 10% of all classes of stock of the Company or any parent or subsidiary
of the Company, the exercise price may not be less than 110% of the fair market value of the common
stock on the date such option is granted. The fair market value of the common stock is generally
determined with reference to the closing sale price for the common stock on the date the option is granted
or the last preceding date for which such quotation exists.

Exercise of Option; Form of Consideration. The Administrator determines when options become

exercisable and may, in its discretion, accelerate the vesting of any outstanding option. The means of
payment for shares issued upon exercise of an option is specified in each option agreement. The 2003
Plan permits payment to be made to the extent permitted under applicable laws by cash, check, other
shares of common stock of the Company (with some restrictions), cashless exercise, any other form of
consideration permitted by applicable law, or any combination thereof.

Term of Option. The term of options granted under the 2003 Plan may be no more than ten years
from the date of grant. Additionally, the maximum term for options granted after January 1, 2006 is seven
years. In the case of an incentive stock option granted to an optionee who owns more than 10% of all
classes of stock of the Company or any parent or subsidiary of the Company, the term of the option may
be no more than five years from the date of grant. No option may be exercised after the expiration of its
term.

Limited Exception to Minimum Vesting Restrictions. Up to five percent (5%) of the total number of
shares of Common Stock available for issuance under the Plan may in the aggregate be issued as awards
of Restricted Stock, Restricted Stock Units, Stock Bonuses or a combination thereof that are not subject
to the minimum vesting requirements set forth in the Plan.

Stock Subject to the Plan. Except for adjustments upon changes in capitalization or merger, the
aggregate number of shares of common stock with respect to which awards of restricted stock, restricted
stock units, stock bonuses or a combination thereof shall be made under the 2003 Plan shall not exceed
50% of the aggregate number of shares of common stock available under the 2003 Plan.

Termination of Employment. If an optionee’s employment or consulting relationship terminates for

any reason (other than death, retirement or disability), then all options held by the optionee under the
2003 Plan expire on the earlier of (1) the date set forth in his or her notice of grant (which date may not
be more than three months after the date of such termination in the case of an incentive stock option or
six months after the date of such termination in the case of a nonstatutory stock option), or (2) the
expiration date of such option. To the extent the option is exercisable at the time of the optionee’s
termination, the optionee may exercise all or part of his or her option at any time before it terminates.
Nonstatutory stock options granted to directors pursuant to the automatic grant provisions of the 2003
Plan will expire on the earlier of (1) three months after the date of termination of the director’s service
relationship for any reason (other than death or disability) or (2) the expiration date of such option.

Disability. If an optionee’s employment or consulting relationship terminates as a result of disability,

then all options held by such optionee under the 2003 Plan expire on the earlier of (1) six months from

16

the date of such termination (or such longer period of time not exceeding 12 months as determined by the
Administrator) or (2) the expiration date of such option. The optionee (or the optionee’s estate or a person
who has acquired the right to exercise the option by bequest or inheritance) may exercise all or part of
the option at any time before such expiration to the extent that the option was exercisable at the time of
such termination. Nonstatutory stock options granted to directors pursuant to the automatic grant
provisions of the 2003 Plan will expire on the earlier of (1) 12 months after the date of termination of the
director’s service relationship as a result of disability or (2) the expiration date of such option.

Death. In the event of an optionee’s death: (1) during the optionee’s employment or consulting
relationship with the Company, the option may be exercised, at any time within six months of the date of
death (or such longer period of time as determined by the Administrator, but no later than the expiration
date of such option) by the optionee’s estate or a person who has acquired the right to exercise the option
by bequest or inheritance, but only to the extent that the optionee’s right to exercise the option would
have accrued if he or she had remained an employee or consultant of the Company six months after the
date of death; or (2) within 30 days (or such other period of time not exceeding three months as
determined by the Administrator) after the optionee’s employment or consulting relationship with the
Company terminates, the option may be exercised at any time within six months (or such other period of
time as determined by the Administrator at the time of grant of the option) following the date of death
(but in no event later than the expiration date of the option) by the optionee’s estate or a person who has
acquired the right to exercise the option by bequest or inheritance, but only to the extent of the optionee’s
right to exercise the option at the date of termination. In the event of a director’s death while serving on
the Board or within 30 days after such director’s service with the Company terminates, nonstatutory stock
options granted to such director pursuant to the automatic grant provisions of the 2003 Plan will expire
on the earlier of (1) 12 months after the date of the director’s death or (2) the expiration date of such
option.

Retirement. The 2003 Plan provides that upon the retirement of any Company employee at age 55

or greater following five or more years of service to the Company, all stock options held by such
employee will vest and be exercisable for a term of three years from the date of retirement. Additionally,
all other stock based awards will fully vest upon retirement with five years of service and age 55.

Other Provisions. The stock option agreement may contain other terms, provisions and conditions

not inconsistent with the 2003 Plan as may be determined by the Administrator.

Automatic Director Grants. Options granted to non-employee directors are “nonstatutory stock options”
to purchase shares of common stock under the 2003 Plan. Any new non-employee director will be granted an
option to purchase 25,000 shares of common stock on the date of his or her initial election or appointment to
the Board of Directors (a “First Option”). In addition, each non-employee director and the Chairman of the
Board of Directors will be automatically granted an annual option (a “Subsequent Option”) to purchase, in the
case of a non-employee director, 12,000 shares, and in the case of the Chairman of the Board of Directors,
15,000 shares, each on the date of each annual meeting of the stockholders of the Company, if on such date,
he or she has served on the Board of Directors for at least six months and will be continuing in office
following the meeting.

The exercise price of the options automatically granted to directors will be equal to 100% of the fair
market value of a share of common stock on the date of grant. First Options and Subsequent Options shall
become exercisable in cumulative monthly installments of 1⁄12 of the shares subject to such option on each of
the monthly anniversaries of the date of grant of the option, commencing with the first such monthly
anniversary, such that each such option shall be 100% vested on the first anniversary of its date of grant. No
portion of an option automatically granted to a director will be exercisable after the 7th anniversary after the
date of option grant. Additionally, an option automatically granted to a director will be exercisable after the
termination of the director’s services as described above.

Restricted Stock Awards. A restricted stock award gives the purchaser a period of no longer than six
months from the date of grant to purchase common stock. The Administrator shall establish the purchase
price, if any, and form of payment for each restricted stock award, which purchase price shall be no less than

17

100% of the fair market value per share on the date of grant; provided that the purchase price per share for a
restricted stock award may be reduced on a dollar-for-dollar basis to the extent the restricted stock award is
granted to the purchaser in lieu of cash compensation otherwise payable to the purchaser. In all cases, legal
consideration shall be required for each issuance of a restricted stock award. A restricted stock award is
accepted by the execution of a restricted stock purchase agreement between the Company and the purchaser,
accompanied by the payment of the purchase price for the shares. Unless the Administrator determines
otherwise, the restricted stock purchase agreement shall give the Company a repurchase option exercisable
upon the voluntary or involuntary termination of the purchaser’s employment or consulting relationship with
the Company for any reason (including death and disability). The purchase price for any shares repurchased
by the Company shall be the original price paid by the purchaser. The repurchase option lapses at a rate
determined by the Administrator.

Stock Bonus Awards. The Administrator may grant a stock bonus award to an employee, director or
consultant that gives the recipient the right to purchase or receive a certain number of shares of common
stock. The Administrator shall establish the purchase price and form of payment for each stock bonus award,
which purchase price shall be no less than 100% of the fair market value per share on the date of grant;
provided that the purchase price per share for a stock bonus award may be reduced on a dollar-for-dollar basis
to the extent the stock bonus award is granted to the purchaser in lieu of cash compensation otherwise payable
to the recipient. A stock bonus award is accepted by the execution of a stock bonus agreement between the
Company and the recipient, accompanied by the payment of the purchase price for the shares, if any. Unless
the Administrator determines otherwise, the stock bonus agreement shall give the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the recipient’s employment or consulting
relationship with the Company for any reason (including death and disability). The purchase price for any
shares repurchased by the Company shall be the original price paid by the purchaser. The repurchase option
lapses at a rate determined by the Administrator.

Restricted Stock Unit Awards. The Administrator may grant restricted stock units to an employee,
director or consultant that gives the recipient the right to purchase or receive a certain number of shares of
common stock. The Administrator is required to establish the purchase price and form of payment for each
restricted stock unit award, which purchase price may be no less than 100% of the fair market value per share
on the date of grant; provided that the purchase price per share for a restricted stock unit may be reduced on a
dollar-for-dollar basis to the extent the restricted stock unit is granted to the purchaser in lieu of cash
compensation otherwise payable to the recipient. The restricted stock unit conveys no rights as a stockholder
to the recipient. A restricted stock unit is accepted by the execution of a restricted stock unit agreement
between the Company and the recipient, accompanied by the payment of the purchase price for the shares, if
any.

Minimum Vesting Requirements for Restricted Stock, Stock Bonus and Restricted Stock Unit
Awards. Except as provided below, all restricted stock awards, stock bonus awards and restricted stock unit
awards that are not performance awards may not vest any earlier than in pro-rata installments over a three
year period measured from the date of grant, and such awards that are performance awards may not vest prior
to the completion of one year of continuous service from the date of grant. However, vesting may occur earlier
upon death, disability, retirement, or a change-in-control. Additionally, up to five percent of the total number
of shares of common stock available for issuance under the 2003 Plan may in the aggregate be issued as any
combination of restricted stock awards, stock bonus awards and restricted stock unit awards that are not
subject to the foregoing vesting restrictions.

Awards Not Transferable. Awards may not be sold, pledged, transferred, or disposed of in any manner
other than by will or by the laws of descent and distribution, or with respect to awards other than incentive
stock options, with the Administrator’s consent, and may be exercised, during the lifetime of the holder, only
by the holder or such transferees as have been transferred an award with the Administrator’s consent. If the
Administrator makes an award transferable, such award shall contain such additional terms and conditions, as
the Administrator deems appropriate.

18

Adjustments upon Changes in Capitalization. In the event that any dividend, distribution, stock split,
reverse stock split, stock dividend, combination, reclassification, reorganization, merger, consolidation, split-up,
repurchase, liquidation, dissolution or sale, transfer, exchange or other disposition of all or substantially all of
the assets of the Company, exchange of common stock or other securities of the Company or other similar
corporate transaction or event, in the Administrator’s discretion, affects the common stock such that an
adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of
the benefits or potential benefits intended to be made available under the 2003 Plan or with respect to awards
granted under the 2003 Plan, appropriate adjustments shall be made in the number and kind of shares of stock
(or other securities or property) subject to the 2003 Plan, the number and kind of shares of stock (or other
securities or property) subject to any award outstanding under the 2003 Plan, and the exercise or purchase
price of any such award.

In the event of a liquidation or dissolution, any unexercised awards will terminate. The Administrator

shall notify the award holders 15 days prior to the consummation of the liquidation or dissolution.

Unless otherwise provided in the award agreement, in the event of a merger, sale of all or substantially
all of the assets of the Company, tender offer or other transaction or series of related transactions resulting in a
change of ownership of more than 50% of the voting securities of the Company, each outstanding award may
be assumed or an equivalent option or right may be substituted by the successor corporation. The vesting of
each outstanding award shall accelerate (i.e. become exercisable immediately in full) in any of the following
events: (1) if the successor corporation refuses to assume the awards, or to substitute substantially equivalent
awards, in which case the Administrator shall notify the award holders and the awards shall be fully vested
and exercisable for 15 days following such notice, and all unexercised awards at the end of such period shall
terminate, (2) if the employment of the optionee is involuntarily terminated without cause within one year
following the date of closing of the merger or acquisition, or (3) if the merger or acquisition is not approved
by the members of the Board of Directors in office prior to the commencement of such merger or acquisition.

Amendment and Termination of the 2003 Plan. The 2003 Plan will continue in effect until terminated
by the Board; provided that no incentive stock option may be granted under the 2003 Plan after May 22, 2013.
The Board may amend, alter, suspend or terminate the 2003 Plan, or any part thereof, at any time and for any
reason. However, the 2003 Plan requires stockholder approval for any amendment to the 2003 Plan to the
extent necessary to comply with applicable laws, rules and regulations. No action by the Board or stockholders
may alter or impair any award previously granted under the 2003 Plan without the consent of the holder.

Federal Income Tax Consequences

Incentive Stock Options. An optionee who is granted an incentive stock option does not recognize taxable

income at the time the option is granted or upon its exercise, although the exercise is an adjustment item for
alternative minimum tax purposes and may subject the optionee to the alternative minimum tax. Upon a
disposition of the shares more than two years after grant of the option and one year after exercise of the
option, any gain or loss is treated as long-term capital gain or loss. If these holding periods are not satisfied,
the optionee recognizes ordinary income at the time of disposition equal to the difference between the exercise
price and the lower of (1) the fair market value of the shares at the date of the option exercise or (2) the sale
price of the shares. Any gain or loss recognized on such a premature disposition of the shares in excess of the
amount treated as ordinary income is treated as long-term or short-term capital gain or loss, depending on the
holding period. A different rule for measuring ordinary income upon such a premature disposition may apply
if the optionee is also an officer, director or 10% stockholder of the Company. Unless limited by
Section 162(m) of the Code, the Company is entitled to a deduction in the same amount as the ordinary
income recognized by the optionee.

Nonstatutory Stock Options. An optionee does not recognize any taxable income at the time he or she is
granted a nonstatutory stock option. Upon exercise, the optionee recognizes taxable income generally measured
by the excess of the then fair market value of the shares over the exercise price. Any taxable income
recognized in connection with an option exercise by an employee of the Company is subject to tax withholding
by the Company. Unless limited by Section 162(m) of the Code, the Company is entitled to a deduction in the

19

same amount as the ordinary income recognized by the optionee. Upon a disposition of such shares by the
optionee, any difference between the sale price and the optionee’s exercise price, to the extent not recognized
as taxable income as provided above, is treated as long-term or short-term capital gain or loss, depending on
the holding period.

Restricted Stock Awards; Stock Bonuses. For federal income tax purposes, if an individual is granted a
restricted stock award or a stock bonus, the recipient generally will recognize taxable ordinary income equal
to the excess of the common stock’s fair market value over the purchase price, if any. However, to the extent
the common stock is subject to certain types of restrictions, such as a repurchase right in favor of the
Company, the taxable event will be delayed until the vesting restrictions lapse unless the recipient makes a
valid election under Section 83(b) of the Code. If the recipient makes a valid election under Section 83(b) of
the Code with respect to restricted stock, the recipient generally will recognize ordinary income at the date of
acquisition of the restricted stock in an amount equal to the difference, if any, between the fair market value
of the shares at that date over the purchase price for the restricted stock. If, however, a valid Section 83(b)
election is not made by the recipient, the recipient will generally recognize ordinary income when the
restrictions on the shares of restricted stock lapse, in an amount equal to the difference between the fair
market value of the shares at the date such restrictions lapse over the purchase price for the restricted stock.
With respect to employees, the Company is generally required to withhold from regular wages or supplemental
wage payments an amount based on the ordinary income recognized. Generally, the Company will be entitled
to a business expense deduction (subject to the requirement of reasonableness, the provisions of Section 162(m)
of the Code and the satisfaction of a tax reporting obligation) equal to the taxable ordinary income realized by
the recipient. Upon disposition of the common stock, the recipient will recognize a capital gain or loss equal
to the difference between the selling price and the sum of the amount paid for such common stock, if any,
plus any amount recognized as ordinary income upon acquisition (or the lapse of restrictions) of the common
stock. Such gain or loss will be long-term or short-term depending on how long the common stock was held.
Slightly different rules may apply to recipients who are subject to Section 16(b) of the Exchange Act.

Restricted Stock Unit Awards. For federal income tax purposes, if an individual is granted a restricted

stock unit award, the recipient generally will not recognize taxable income upon such issuance. However,
when a restricted stock unit award vests and/or the underlying shares are issued to the recipient, the recipient
generally will recognize taxable ordinary income equal to the excess of the common stock’s fair market value
over the purchase price, if any, on the vesting or distribution date. With respect to employees, the Company is
generally required to withhold from regular wages or supplemental wage payments an amount based on the
ordinary income recognized. Generally, the Company will be entitled to a business expense deduction (subject
to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a
tax reporting obligation) equal to the taxable ordinary income realized by the recipient. Upon disposition of
the common stock, the recipient will recognize a capital gain or loss equal to the difference between the
selling price and the sum of the amount paid for such common stock, if any, plus any amount recognized as
ordinary income upon acquisition (or the lapse of restrictions) of the common stock. Such gain or loss will be
long-term or short-term depending on how long the common stock is held. Slightly different rules may apply
to recipients who are subject to Section 16(b) of the Exchange Act.

Potential Limitation on Company Deductions. Section 162(m) of the Code denies a deduction to any
publicly held corporation for compensation paid to certain “covered employees” in a taxable year to the extent
that compensation exceeds $1 million for a covered employee. It is possible that compensation attributable to
awards granted in the future under the 2003 Plan, when combined with all other types of compensation
received by a covered employee from the Company, may cause this limitation to be exceeded in any particular
year. Certain kinds of compensation, including qualified “performance-based compensation,” are disregarded
for purposes of the deduction limitation. In accordance with Treasury regulations issued under Section 162(m)
of the Code, compensation attributable to stock options will qualify as performance-based compensation,
provided that: (1) the stock award plan contains a per-employee limitation on the number of shares for which
awards may be granted during a specified period; (2) the per-employee limitation is approved by the
stockholders; (3) the award is granted by a compensation committee comprised solely of “outside directors”;
and (4) the exercise price of the award is no less than the fair market value of the stock on the date of grant.

20

Restricted stock awards and stock bonus awards qualify as performance-based compensation under the

Treasury regulations only if: (1) the award is granted by a compensation committee comprised solely of
“outside directors”; (2) the award is earned (typically through vesting) only upon the achievement of an
objective performance goal established in writing by the compensation committee while the outcome is
substantially uncertain; (3) the compensation committee certifies in writing prior to the earning of the awards
that the performance goal has been satisfied; and (4) prior to the earning of the award, stockholders have
approved the material terms of the award (including the class of employees eligible for such award, the
business criteria on which the performance goal is based, and the maximum amount (or formula used to
calculate the amount) payable upon attainment of the performance goal).

The 2003 Plan has been designed to permit the compensation committee to grant stock options, restricted

stock awards, restricted stock unit awards and stock bonus awards which will qualify as “performance-based
compensation.” However, restricted stock awards, restricted stock unit awards and stock bonus awards granted
to date have not been structured to so qualify.

The foregoing is only a summary of the effect of federal income taxation upon optionees, holders of
restricted stock awards, restricted stock unit awards or stock bonus awards and the Company with respect
to the grant and exercise of awards under the 2003 Plan. It does not purport to be complete, and does not
discuss the tax consequences of the employee’s or consultant’s death or the provisions of the income tax
laws of any municipality, state or foreign country in which the employee or consultant may reside.

(1) Value based on the closing price of the Company’s common stock on December 31, 2008 of $3.20.

(2) Mr. Lyons did not receive any grants in his capacity as an executive officer during the fiscal year ended
December 31, 2008. However, he did receive an option grant in his capacity as a current non-executive
director.

(3) Pursuant to the terms of the 2003 Plan, non-employee directors are entitled to receive First Options and

Subsequent Options as described in “Automatic Director Grants” above. Currently the Company has seven
non-employee directors, all of whom are eligible to receive Subsequent Options on the day of the Annual
Meeting. The actual value realized upon exercise of an option will depend on the excess, if any, of the
stock price over the exercise price on the date of exercise. Only non-employee directors of the Company
are eligible to receive automatic grants under the 2003 Plan. All other grants under the 2003 Plan are
within the discretion of the Board or its committee and the benefits of such grants are, therefore, not
determinable.

Total

(1) Number of shares remaining available for future issuance under equity compensation plans as of

December 31, 2008 is from the 2003 Plan. The shares available for issuance under the 2003 Plan may be
issued in the form of option awards, restricted stock awards, restricted stock unit awards or stock bonus
awards subject to limitations set forth in the 2003 Plan. The amounts in this table do not include the shares
covered by the amendment to the 2003 Plan discussed in Proposal Three.

(2) Consists of shares of common stock issuable under the Company’s 2001 Stock Option Plan, as amended
(the “2001 Plan”) under which no further awards will be made, and an employment commencement non-
statutory stock option award. See the descriptions below.

Summary of the 2001 Stock Option Plan

The essential features of the 2001 Plan are summarized below. This summary does not purport to be

complete and is subject to, and qualified by reference to, all provisions of the 2001 Plan.

General. The purpose of the 2001 Plan was to attract and retain the best available personnel, to provide

additional incentive to the employees and consultants of the Company and to promote the success of the
Company’s business. Effective May 22, 2003, options and stock purchase rights may no longer be granted
under the 2001 Plan.

Administration. The 2001 Plan may generally be administered by the Board of Directors or a Committee
appointed by the Board (in either case, the “Administrator”). The Administrator may make any determinations
deemed necessary or advisable for the Plan.

22

Eligibility. Nonstatutory stock options and stock purchase rights may have been granted under the 2001

Plan to employees and consultants (including officers and directors) of the Company and any parent or
subsidiary of the Company; provided that the aggregate number of shares issued or reserved for issuance
pursuant to options granted to persons other than officers exceeded fifty percent (50%) of the total number of
shares issued or reserved for issuance pursuant to options granted under the 2001 Plan. The Administrator, in
its discretion, selected the employees and consultants to whom options and stock purchase rights may have
been granted, the time or times at which such options and stock purchase rights were granted, and the number
of shares subject to each such grant.

Terms and Conditions of Options. Options granted under the 2001 Plan were nonstatutory stock options.

Each such option is evidenced by a stock option agreement between the Company and the optionee, and is
subject to the following additional terms and conditions:

Exercise Price. The Administrator determined the exercise price of options at the time the options
were granted. The exercise price of a nonstatutory stock option was no less than the par value per share
on the date of grant. The fair market value of the common stock was determined with reference to the
closing sale price for the common stock (or the closing bid if no sales were reported) on the last market
trading day prior to the date the option was granted.

Exercise of Option; Form of Consideration. The Administrator determines when options become

exercisable and may, in its discretion, accelerate the vesting of any outstanding option. The means of
payment for shares issued upon exercise of an option is specified in each option agreement. The Plan
permits payment to be made by cash, check, bearing a market rate of interest, other shares of common
stock of the Company (with some restrictions), cashless exercise, any other form of consideration
permitted by applicable law, or any combination thereof.

Term of Option. The term of options is no more than 10 years from the date of grant. No option

may be exercised after the expiration of its term.

Termination of Employment. If an optionee’s employment or consulting relationship terminates for

any reason (other than death, retirement or disability), then all options held by the optionee under the
2001 Plan expire on the earlier of (i) the date set forth in his or her notice of grant (which date is
typically six months after the date of such termination), or (ii) the expiration date of such option. To the
extent the option is exercisable at the time of the optionee’s termination, the optionee may exercise all or
part of his or her option at any time before it terminates.

Disability. If an optionee’s employment or consulting relationship terminates as a result of disability,

then all options held by such optionee under the 2001 Plan expire on the earlier of (i) six months from
the date of such termination (or such other period of time as determined by the Administrator) or (ii) the
expiration date of such option. The optionee (or the optionee’s estate or a person who has acquired the
right to exercise the option by bequest or inheritance) may exercise all or part of the option at any time
before such expiration to the extent the right to exercise would have accrued had the optionee remained
an employee or consultant for a period of six months from the time of termination due to disability.

Death. In the event of an optionee’s death: (i) during the optionee’s employment or consulting
relationship with the Company, the option may be exercised, at any time within six months of the date of
death (or at such later time as may be determined by the Administrator but in no event later than the
expiration date of such option) by the optionee’s estate or a person who has acquired the right to exercise
the option by bequest or inheritance, but only to the extent that the optionee’s right to exercise the option
would have accrued if he or she had remained an employee or consultant of the Company six months
after the date of death; or (ii) within 30 days (or such other period of time as determined by the
Administrator) after the optionee’s employment or consulting relationship with the Company terminates,
the option may be exercised at any time within six months (or such other period of time as determined by
the Administrator) following the date of death (but in no event later than the expiration date of the
option) by the optionee’s estate or a person who has acquired the right to exercise the option by bequest

23

or inheritance, but only to the extent of the optionee’s right to exercise the option at the date of
termination.

Retirement. The 2001 Plan provides that upon the retirement of any Company employee at age 55

or greater following five or more years of service to the Company, all stock options held by such
employee will vest and be exercisable for a term of three years from the date of retirement.

Nontransferability of Options. Unless otherwise determined by the Administrator, options granted
under the 2001 Plan are not transferable other than by will or the laws of descent and distribution, and
may be exercisable during the optionee’s lifetime only by the optionee.

Other Provisions. The stock option agreement may contain other terms, provisions and conditions

not inconsistent with the 2001 Plan as may be determined by the Administrator.

Stock Purchase Rights. A stock purchase right gives the purchaser a period of no longer than six months
from the date of grant to purchase common stock. The purchase price of common stock purchased pursuant to
a stock purchase right granted under the 2001 Plan was determined in the same manner as for nonstatutory
stock options. Each such stock purchase right was accepted by the execution of a restricted stock purchase
agreement between the Company and the purchaser, accompanied by the payment of the purchase price for the
shares. Unless the Administrator determines otherwise, the restricted stock purchase agreement gives the
Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s
employment or consulting relationship with the Company for any reason (including death and disability). The
purchase price for any shares repurchased by the Company shall be the original price paid by the purchaser.
The repurchase option lapses at a rate determined by the Administrator. A stock purchase right is nontransfer-
able other than by will or the laws of descent and distribution, and may be exercisable during the optionee’s
lifetime only by the optionee.

Adjustments upon Changes in Capitalization. In the event that the stock of the Company changes by
reason of any stock split, reverse stock split, stock dividend, combination, reclassification or other similar
change in the capital structure of the Company effected without the receipt of consideration, appropriate
adjustments shall be made in the number and class of shares of stock subject to the 2001 Plan, the number and
class of shares of stock subject to any option or stock purchase right outstanding under the 2001 Plan, and the
exercise price of any such outstanding option or stock purchase right.

In the event of a liquidation or dissolution, any unexercised options or stock purchase rights will

terminate. The Administrator shall notify the optionee 15 days prior to the consummation of the liquidation or
dissolution. To the extent it has not been previously exercised, the option or stock purchase right shall
terminate immediately prior to the consummation of such proposed action.

In connection with any merger, consolidation, acquisition of assets or like occurrence involving the
Company, each outstanding option or stock purchase right may be assumed or an equivalent option or right
may be substituted by the successor corporation. The vesting of each outstanding option or stock purchase
right shall accelerate (i.e. become exercisable immediately in full) in any of the following events: (1) if the
successor corporation refuses to assume the option or stock purchase rights, or to substitute substantially
equivalent options or rights, (2) if the employment of the optionee is involuntarily terminated without cause
within one year following the date of closing of the merger or acquisition, or (3) if the merger or acquisition
is not approved by the members of the Board of Directors in office prior to the commencement of such merger
or acquisition.

Amendment and Termination of the Plan. The Board may amend, alter, suspend or terminate the 2001

Plan, or any part thereof, at any time and for any reason. However, the 2001 Plan requires stockholder
approval for any amendment to the 2001 Plan to the extent necessary to comply with applicable laws, rules
and regulations. No action by the Board or stockholders may alter or impair any option or stock purchase right
previously granted under the 2001 Plan without the consent of the optionee. Unless terminated earlier, the Plan
shall terminate ten years from the date of its approval by the stockholders or the Board of the Company,
whichever is earlier.

24

Summary of the Employment Commencement Nonstatutory Stock Option

The Company granted an employment commencement nonstatutory stock option award (the “Option”) to

one of the current executive officers of the Company in connection with, and as an inducement to, his
employment with the Company. The essential features of the Option are summarized below. This summary
does not purport to be complete and is subject to, and qualified by reference to, all provisions of the Option
Agreement with the executive officer. The Option covers the right to purchase an aggregate of 55,000 shares
of the Company’s common stock at an exercise price of $52.82 per share. The Option is nonstatutory for tax
purposes and may not be transferred other than by will or the laws of descent and distribution.

Exercise of Option; Form of Consideration; Term of Options. The Option vests and becomes exercisable

with respect to 25% of the shares 12 months after issuance and with respect to an additional 1⁄48 of the shares
each month thereafter, subject to the Optionee continuing to be an employee or consultant. The Option permits
payment to be made by cash, check, other shares of common stock of the Company (with some restrictions),
cashless exercise, any other form of consideration permitted by applicable law, or any combination thereof.
The term of the Option is 10 years from the date of grant. The Option may not be exercised after the
expiration of its term.

Termination of Employment; Retirement. If the Optionee’s employment terminates for any reason other
than death or disability, then his Option expires on the earlier of (i) 90 days after the date of such termination
or (ii) the expiration date of such Option. If the Optionee’s employment terminates upon death or disability,
then his Option expires on the earlier of (i) six months after the date of such termination or (ii) the expiration
date of such Option. The Option provides that upon the retirement of the Optionee at age 55 or greater
following five or more years of service to the Company, his Option will vest and be exercisable for a term of
three years from the date of retirement.

Adjustments upon Changes in Capitalization. In the event that the stock of the Company changes by
reason of any stock split, reverse stock split, stock dividend, combination, reclassification or other similar
change in the capital structure of the Company effected without the receipt of consideration, appropriate
adjustments shall be made in the number and class of shares of stock subject to the Option and the exercise
price of the Option. In connection with any merger, consolidation, acquisition of assets or like occurrence
involving the Company, the Option may be assumed or an equivalent option or right may be substituted by the
successor corporation. The vesting of the Option right shall accelerate (i.e., become exercisable immediately in
full) in any of the following events: (1) if the successor corporation refuses to assume the Option, or to
substitute substantially equivalent options, (2) if the employment of the Optionee is involuntarily terminated
without cause within one year following the date of closing of the merger or acquisition, or (3) if the merger
or acquisition is not approved by the members of the Board of Directors in office prior to the commencement
of such merger or acquisition.

PROPOSAL FOUR: STOCKHOLDER PROPOSAL TO DECLASSIFY
THE BOARD OF DIRECTORS

General

The Comptroller of the City of New York is the custodian and trustee of the New York City Teachers’
Retirement System, the New York City Police Pension Fund and the New York City Fire Department Pension
Fund and the custodian of the New York City Board of Education Retirement System. The address of such
stockholders is: The City of New York, Office of the Comptroller, Bureau of Asset Management, 1 Centre
Street, New York, NY 10007-2341.

The stockholders identified above own an aggregate of 74,664 shares of our common stock and have
submitted the following proposal for consideration in this proxy statement. We are not responsible for any of
the contents of the language of the stockholder proposal, which is included below in italics and between
quotation marks. The Board unanimously opposes this stockholder proposal for the reasons stated in the

25

“Statement in Opposition of the Stockholder Proposal to Declassify the Board of Directors,” which follows the
stockholder proposal.

“Submitted by William C. Thompson, Jr., Comptroller, City of New York, on behalf of the Boards of
Trustees of the New York City Teachers’ Retirement System, the New York City Police Pension Fund, the
New York City Fire Department Pension Fund, and the New York City Board of Education Retirement System

BE IT RESOLVED, that the stockholders of Neurocrine Biosciences, Inc. request that the Board of
Directors take the necessary steps to declassify the Board of Directors and establish annual elections of
directors, whereby directors would be elected annually and not by classes. This policy would take effect
immediately, and be applicable to the re-election of any incumbent director whose term, under the current
classified system, subsequently expires.

SUPPORTING STATEMENT

We believe that the ability to elect directors is the single most important use of the shareholder franchise.
Accordingly, directors should be accountable to shareholders on an annual basis. The election of directors by
classes, in our opinion, minimizes accountability and precludes the full exercise of the rights of shareholders
to approve or disapprove annually the performance of a director or directors.

In addition, since only a fraction of the Board of Directors is elected annually, we believe that classified

boards could frustrate, to the detriment of long-term shareholder interest, the efforts of a bidder to acquire
control or a challenger to engage successfully in a proxy contest.

We urge your support for the proposal to repeal the classified board and establish that all directors be

elected annually.”

STATEMENT IN OPPOSITION OF THE STOCKHOLDER PROPOSAL
TO DECLASSIFY THE BOARD OF DIRECTORS

Our Certificate of Incorporation currently provides for a “classified board,” which is divided into three

classes. The members of each class are elected to serve staggered three-year terms. The current classified
board structure has been in place since our initial public offering in 1996. This same non-binding stockholder
proposal was submitted at our 2007 and 2008 Annual Meetings of Stockholders. At the 2007 and 2008
meetings, the proposal received approximately 54% and 68%, respectively, of the votes cast on the proposal
(including abstentions) and was therefore approved, but the affirmative votes represented substantially less than
half of our outstanding shares as of the record date for the meetings. As described below, the vote that would
be necessary to actually repeal the classified board provisions of our Certificate of Incorporation would be the
affirmative vote of the holders of a majority of our outstanding common stock — a threshold beyond the
affirmative votes cast in favor of the proposal at the 2007 and 2008 Annual Meetings. In addition, we continue
to believe that our classified board structure offers important advantages and continues to be in the best
interests of the Company and our stockholders.

Continuity and Stability. We believe that a classified Board enhances continuity and stability in our

management and policies since a majority of the directors at any given time will have had prior experience
and familiarity with our business. This continuity and stability fosters a greater focus on long-term strategic
planning and other areas of oversight, thereby enhancing our value to stockholders. We believe that the long-
term perspective resulting from Board continuity and stability is particularly important for a company such as
ours that is engaged in the research and development of pharmaceutical products, given the significant time,
money and effort that is required to successfully develop and commercialize such products, the fundamentally
unpredictable nature of drug development, and the inherent volatility in stock prices for biotechnology and
pharmaceutical companies. Moreover, this continuity helps us attract and retain qualified individuals willing to
commit the time and dedication necessary to understand the Company, our operations and our competitive
environment — and who we believe are therefore better positioned to make decisions that benefit our
stockholders.

26

Protection Against Hostile Bidders. In the event of an unfriendly or unsolicited effort to take over or
restructure the Company, the classified Board structure facilitates our ability to obtain the best outcome for
stockholders by giving us time to negotiate with the entity seeking to gain control of the Company and to
consider alternative methods of maximizing stockholder value. If a corporation has a classified board and a
hostile bidder stages and wins a proxy contest at the corporation’s annual meeting, the bidder can replace
approximately one-third of the existing directors at that meeting, meaning that the bidder would need to stage
and win a second proxy contest at the next annual meeting to gain control of the board. In contrast, if the
corporation’s board was declassified, a hostile bidder could at the first annual meeting replace a majority of
the directors with directors who are friendly to the bidder. Declassification of the Board would eliminate these
benefits and therefore provide us with less time to evaluate a takeover proposal, negotiate the best result for
all stockholders and consider alternatives.

Accountability to Stockholders. In the opinion of the Board, directors of a classified board are just as

accountable to stockholders as those on an annually elected board. Since approximately one-third of our
directors stand for election each year, stockholders have the opportunity annually to vote against, or withhold
their votes from, those directors as a way of expressing any dissatisfaction with the Board or management.
Moreover, the entire Board can be replaced in the course of three annual meetings, all held within
approximately two years. Our directors believe that they are no less attentive to stockholder concerns as a
result of having been elected to three-year terms, and that they are equally accountable to the stockholders in
years when they do not face re-election. The Board is committed to the highest quality of corporate
governance and has adopted Corporate Governance Guidelines that, among other things, focus on the
independence of our directors and the effective performance and functioning of the Board.

Effect of the Stockholder Proposal. Approval of the stockholder proposal requires the affirmative vote of
the holders of a majority of the shares represented in person or by proxy at the meeting. However, approval of
the proposal would not automatically eliminate the classified Board, as it is a non-binding proposal requesting
that the Board take the necessary steps to declassify the Board. A formal amendment repealing the classified
board provisions of our Certificate of Incorporation would need to be approved by the Board and submitted to
our stockholders at a subsequent meeting, and it would require approval by the affirmative vote of the holders
of a majority of our outstanding common stock.

Vote Required

The affirmative vote of the holders of a majority of the shares represented in person or by proxy at the
Annual Meeting will be required to approve the stockholder proposal to declassify the Board of Directors. The
Board of Directors unanimously recommends voting “AGAINST” the stockholder proposal to declassify
the Board of Directors.

COMPENSATION DISCUSSION AND ANALYSIS

Overview and Role of the Compensation Committee

The Compensation Committee (“Committee”) reviews and recommends to the Board of Directors for

approval the Company’s executive compensation policies.

The specific roles of the Committee include:

(cid:129) reviewing and, if necessary, revising the compensation philosophy of the Company;

(cid:129) reviewing and approving corporate goals and objectives relating to the compensation of the Company’s
executive officers, and evaluating the performance of the Company’s executive officers in light of the
Company’s goals and objectives;

(cid:129) reviewing and approving all employment agreements and compensation for all executive officers and
guidelines for salaries, merit salary increases, bonus payments, stock based grants and performance
stock based grants for all other employees of the Company;

(cid:129) reviewing and approving all promotions to executive officers and all new hires of executive officers;

(cid:129) managing and reviewing equity incentive, employee pension and benefit plans;

(cid:129) managing and reviewing the grant of perquisite benefits;

(cid:129) managing and reviewing executive officer and director indemnification and insurance matters; and

(cid:129) overseeing the preparation of, and approving, this section of the Company’s annual proxy statement.

Compensation Philosophy and Objectives

The Committee’s philosophy in establishing the Company’s compensation policy for executive officers

and other employees is to:

(cid:129) create a structure designed to attract and retain highly skilled individuals by establishing salaries,

benefits, and incentive compensation which compare favorably with those for similar positions in other
biotechnology companies; and

(cid:129) align compensation plans to both short-term and long-term goals and objectives of the Company.

In light of the Company’s philosophy, the Committee attempts to provide a mix of compensation between

base salary and cash bonuses such that approximately 30% to 40% of the executive officer’s total cash
compensation is at risk and that non-cash compensation is structured to provide a reward for corporate and
individual performance. The Committee believes that this approach provides an appropriate incentive for
executive officers to attain the Company’s long-term strategic and performance goals, and also retains and
motivates key executive officers. Although current general economic conditions in 2008 played a role in

29

determining the amount of compensation awards for 2009, the Company made no changes to its compensation
philosophy and objectives due to these conditions.

Role of Peer Group, Compensation Surveys and Consultants

In order to evaluate the Company’s competitive position in the industry related to executive compensation,
the Committee has historically reviewed and analyzed the compensation packages, including base salary levels,
cash bonus awards and equity awards, offered by other biotechnology and pharmaceutical companies within a
designated peer group.

As a result of a significant reduction of the Company’s workforce, changes to the management team and

a significant decrease in the Company’s market capitalization in late 2007 and early 2008, the Committee
believed that the 2007 peer group of companies no longer represented an appropriate peer group for the
Company. Accordingly, when reviewing the Company’s executive compensation policies for 2008 and making
recommendations to the Board regarding such policies, and in setting 2008 compensation levels, the
Committee used information obtained directly from the Radford Global Life Sciences Survey (“Radford
Survey”). The Radford Survey is the leading source for compensation information in the biotechnology
industry. Because the Committee viewed the Company as being in a transition stage due to the events
described above, the Committee used data from the overall results and similarly sized company sections of the
Radford Survey in setting 2008 compensation levels.

During 2008, the Committee determined that the Company would have completed its transition by year

end and therefore established a new peer group to be used in setting 2009 compensation levels. This peer
group was selected based on a variety of factors including business scope, market capitalization, stage of
development, location and/or competition for talent, and consists of Acadia Pharmaceuticals, Inc., Alexza
Pharmaceuticals, Inc., Arena Pharmaceuticals, Inc., CombinatoRx, Inc., Cytokinetics Incorporated, Dendreon
Corporation, Geron Corporation, Halozyme Therapeutics, Inc., Incyte Corporation, Indevus Pharmaceuticals,
Inc., Infinity Pharmaceuticals, Inc., ISIS Pharmaceuticals, Inc., Metabasis Therapeutics, Inc., Peregrine
Pharmaceuticals, Inc., Rigel Pharmaceuticals, Inc., Santarus, Inc., Seattle Genetics, Inc., Somaxon
Pharmaceuticals, Inc., Sunesis Pharmaceuticals, Inc., Theravance, Inc., Trubion Pharmaceuticals, Inc. and Vical
Incorporated.

Compensation Consultant

The Committee used the services of Remedy Compensation Consulting (the “Compensation Consultant”)
as a third party compensation consultant for establishing 2008 and 2009 compensation levels. The Compensa-
tion Consultant worked closely with the Committee in re-defining the peer group for 2009. The Compensation
Consultant was engaged directly by the Committee, and its contract and related services are at the sole
discretion of the Committee.

Establishment of 2008 Employee Retention Program

In February 2008, the Board approved an employee retention program (“the Retention Program”) to
provide the Company with a mechanism to retain its non-officer and executive officer employees who were
not subject to the December 2007 reduction in the Company’s workforce. At the time, the Committee believed
that employee and executive retention over the following two to three years was critical. As part of the
Retention Program, the Board approved a one-time cash retention amount and the issuance of RSUs and stock
options to its executive officers. The Retention Program was intended to provide both a short-term incentive to
stay and a long-term incentive to help the Company meet its goals and objectives as well as retain those
receiving the equity awards. The Committee reviewed each compensation component separately and in total
versus the data obtained from the Radford Survey and determined that the executive compensation components
of the Retention Program fell within the targeted ranges for executive compensation set forth below.

30

Role of Executive Officers in Compensation Decisions

The Committee makes all final decisions regarding compensation for all executive officers (other than

compensation for the President and Chief Executive Officer, which is decided by all non-employee members
of the Board of Directors), including determining equity awards. The President and Chief Executive Officer
annually reviews the performance of each executive officer (other than himself). The Committee reviews
competitive market data for base salary, cash bonuses and equity awards. In addition, both the Committee and
the Chief Executive Officer consulted with the Compensation Consultant in establishing the compensation
levels for 2008 and 2009. From this review, conclusions and recommendations, including proposed base salary
adjustments and annual award amounts, are presented to the Committee for its consideration and approval.
The Committee, in its sole discretion, can accept, modify or reject any of the recommendations.

Components of Compensation

The Company’s compensation for executive officers consists of six components: base salary, cash

bonuses, equity awards, deferred compensation benefits, retirement benefits as provided under the Company’s
401(k) plan, and severance agreements and other benefits. Due to the importance of the role, higher level of
responsibility and enhanced stockholder accountability, the President and Chief Executive Officer typically
receives a greater total compensation package, including stock equity grants. Base salaries, cash bonuses and
equity award components of compensation are targeted at or above the average rates reflected by the Radford
Survey for 2008 compensation and the peer group for 2009 compensation. Generally, this means targeting each
of these three components between the 50th and 75th percentile of the actual benefits for all incumbents in an
appropriately comparable position as reflected by the Radford Survey for 2008 compensation and the peer
group for 2009 compensation. Using significant discretion, the Committee considers each executive’s respon-
sibilities, experience, and contribution to goals when determining the appropriate compensation level for each
executive within the target percentiles. In turn, these same components, when added together, are also within
these same targeted percentiles for compensation levels as compared to the Radford Survey for 2008
compensation and the peer group for 2009 compensation. There is no direct correlation between how amounts
paid for one component affect amounts paid under another component. Each of these six components is
described below.

Base Salary

The base salary component of compensation is designed to compensate executive officers competitively at

levels necessary to attract and retain qualified executives in the pharmaceutical and biotechnology industry.
For 2008 and 2009 compensation, base salaries have been targeted between the 50th and 75th percentiles of
rates reflected by the Radford Survey and the 2009 peer group, respectively, to enable the Company to attract,
motivate, reward and retain highly skilled executives. As a general matter, the base salary for each executive
officer is initially established through negotiation at the time the officer is hired, taking into account such
officer’s qualifications, experience, prior salary, and competitive salary information. Year-to-year adjustments
to each executive officer’s base salary are based upon personal performance for the year, changes in the
general level of base salaries of persons in comparable positions within the industry, and the average merit
salary increase for such year for all employees of the Company established by the Committee, as well as other
factors the Committee judges to be pertinent during an assessment period. In making base salary decisions, the
Committee exercises its judgment to determine the appropriate weight to be given to each of these factors.

Cash Bonuses

The Committee’s philosophy in establishing the Company’s cash bonus compensation strategy for

executive officers and other employees is to provide a mix of compensation between base salary and total cash
compensation such that approximately 30% to 40% of the total target cash compensation is at risk for
executives during 2009. The cash bonus targets at plan were set between the 50th and 75th percentiles of
target bonuses reflected by the Radford Survey for 2008 compensation and the peer group for 2009
compensation to enable the Company to attract, motivate, reward and retain highly skilled executives for

31

short-term performance. This supports the achievement of annual Company goals and objectives by basing
compensation on a pay-for-performance basis.

To promote a pay-for-performance environment, the Company maintains a discretionary performance-
based annual bonus program for its executive officers. Bonus payments are linked to the attainment of overall
corporate goals established by the Board of Directors and individual performance for each executive officer.
The Board of Directors establishes the target and maximum potential amount of each officer’s bonus payment
annually, based upon the recommendation of the Committee. Normally an appropriate weight is given to each
of the various goals used to calculate the amount of each executive officer’s bonus payment as determined by
the Committee in its sole discretion.

In February 2008, the Board approved the Company’s performance goals for 2008 along with eligible

bonus percentages and weighting for executive officers. The Board decreased the President and Chief
Executive Officer’s bonus target percentage to 60% of base salary for 2008; this placed the President and
Chief Executive Officer’s target bonus closer to the 50th percentile of bonus targets in the Radford Survey. All
other executive officers’ eligible bonus at target remained at 50% of their respective base salaries and
maximum bonus payouts (which was the same as in 2007) as both the target and maximum levels were
substantially similar to the Radford Survey data. In addition, the Company no longer has an executive in the
position of Chief Operating Officer. The performance goals for 2008 related to our lead development programs
which comprise mainly GnRH, CRF, and urocortin 2, our earlier stage research and development programs
and general administration activities. The Committee assigned a weighting of 55%, 25% and 20%, respec-
tively, for each of these areas. Some of the specific 2008 goals were as follows: for the GnRH and urocortin 2
programs, the continuation of various clinical and pre-clinical development studies and entering into a research
and development partnership for GnRH; for our earlier stage research and development program goals, the
continuation of various pre-clinical development studies, preparation for clinical studies and various research
and drug discovery goals; and for general administrative activities, maintaining the projected cash burn,
exceeding the NASDAQ biotechnology and composite indices’ returns, and supplementing the early stage drug
development pipeline.

In general, achievement of the Company’s goals determines the initial bonus pool for the Company,
which is then allocated to the executive officers based on the individual performance of each executive officer
during the year. As in previous years, the 2008 executive bonuses were discretionary and there were no
formulaic calculations for determining the actual amount of the bonus for each executive. Accordingly, the
Board or the Committee may, in its sole discretion, eliminate any individual bonus or reduce or increase the
amount of compensation payable with respect to any individual bonus. An executive officer must be an
employee of the Company on the date of payment to qualify for a bonus. Any executive officer who leaves
the employment of the Company, voluntarily or involuntarily, prior to the payment, is ineligible for any bonus.
An employee who becomes an executive officer during the fiscal year may be eligible for a pro-rated bonus at
the option of the Committee, provided the executive has been employed a minimum of three months during
the calendar year. No clawback provisions have been adopted at this time. The Committee believes that the
performance goals established for bonuses do not encourage excessive risk taking or have potential for
encouraging behavior that may impact the Company negatively in future years.

For 2008, executive officers were eligible for the following bonuses as a percentage of annualized base

salary:

In reviewing performance for 2008, the Committee determined that a majority of the corporate goals had
been met. Goals for GnRH included generation of positive top-line results for the 603 study, and initiation of
the 702 and 703 studies for GnRH; however, the goal of obtaining a partnership was not reached. Other goals
achieved included the pre-clinical work for urocortin 2, and the advancement of another compound, a VMAT2
inhibitor, which is now ready for clinical development. Most of the early stage research and development

32

program goals were completed, including various pre-clinical development studies, preparation for clinical
studies and advancement of drug candidates in the research and drug discovery areas. General administrative
goals achieved include maintaining the projected cash burn, ending 2008 with over $100 million in cash and
investments and reorganizing the Company in early 2008. Notwithstanding the achievement of the majority of
the corporate goals for the year, the Committee determined that no annual bonus payment would be awarded
to the executive officers for 2008. This was primarily due to the failure to obtain a partnership for the GnRH
program coupled with the need for the Company to conserve cash at this time.

In February 2009, the Board approved the Company’s performance goals for 2009 along with eligible
bonus percentages and weighting for executive officers. The performance goals for 2009 include goals for lead
development programs, research and general administration. GnRH program goals include continuation of
various clinical and pre-clinical development studies and entering into a partnership for GnRH. Early stage
research and development program goals include various pre-clinical development studies, preparation for
clinical studies and various research and drug discovery goals. VMAT2 goals include initiating a Phase I trial
and other pre-clinical activities. General administrative activities include maintaining the projected cash burn
and budgetary goals.

Equity Awards

The Committee provides the Company’s executive officers with long-term incentive compensation through

grants of stock options, restricted stock units (“RSU“s) and/or stock bonuses under the Company’s equity
compensation plans. These equity-based programs provide the Company’s executive officers with the opportu-
nity to purchase and maintain an equity interest in the Company and to share in the appreciation of the value
of the Company’s common stock. The Committee believes that these grants directly motivate an executive to
maximize long-term stockholder value and create an effective tool for incentivizing and retaining those
executives who are most responsible for influencing stockholder value by further aligning our executive’s
interests with those of our stockholders by increasing the reward to our executives when our stock price
increases. The grants also utilize vesting periods that encourage key executives to continue in the employ of
the Company. The Committee considers each grant subjectively, considering factors such as the individual
performance of the executive officer, the anticipated contribution of the executive officer to the attainment of
the Company’s long-term strategic performance goals, and to retain and motivate key executives. The equity
awards for each year are set between the 50th and 75th percentiles of the actual benefits reflected by the
Radford Survey for 2008 and by the peer group in 2009 to enable the Company to attract, motivate, and retain
highly skilled executives. Long-term incentives granted in prior years are also taken into consideration, but do
not play a significant role in current year determinations.

It has been our practice to make equity-based awards to our executives on an annual basis. Annual stock
option awards typically vest over three years and have a seven year term. Additionally, all stock option awards
are priced based upon the closing price of the Company’s common stock on the date of grant, which is also
the approval date, by the Committee or Board of Directors. RSU awards typically vest over three years. The
Committee typically reviews Company and executive performance during the first quarter of each year to
determine the amount and types of awards to be granted. Prior year actual gains from the exercise of vested
equity grants are not considered in the determination of current year compensation. The Company does not
maintain any equity ownership guidelines for its executive officers.

Deferred Compensation Plan

Currently, employees at the Vice President level or above, inclusive of members of the Board of

Directors, are eligible to participate in the Company’s Deferred Compensation Plan (the “NQDC Plan”). Under
the terms of the NQDC Plan, each eligible participant may elect to defer all or a portion of cash salary and
bonus compensation, and RSUs received for services to the Company. The plan was established for the
purpose of providing retirement and other benefits on behalf of such employees. The plan is intended to be a
nonqualified unfunded top-hat plan maintained primarily for the purpose of providing deferred compensation
benefits for a select group of management or highly compensated employees. We do not provide a match on

33

executive deferrals under the deferred compensation plan. We maintain this plan for the purpose of providing a
competitive benefit allowing our executives an opportunity to defer income tax payments on their cash and
equity compensation.

Retirement Benefits

The terms of the Company’s 401(k) Savings Plan (the “401k Plan”), provide for executive officer and
broad-based employee participation. Under the 401k Plan, all Company employees are eligible to receive basic
matching contributions from the Company that vest three years from date of hire and monthly thereafter. The
Company’s basic matching contribution for the 401k Plan for 2008 was $0.50 for each dollar on the first 6%
of each participant’s pretax contributions and was calculated on a payroll-by-payroll basis subject to applicable
Federal matching limits ($6,900 in 2008). Beyond the basic matching contribution, the Company made no
discretionary contributions to the 401k Plan in 2008.

Severance Agreements and other Benefits

Executive officers are eligible to participate in the Company’s employee benefit plans on the same terms

as all other full-time employees. These plans include medical, dental and life insurance. In addition to the
benefits available to all employees, we provide our executive officers with certain additional benefits that we
believe reflect market standards and are reasonable and necessary to attract and/or retain each of our executive
officers and, in the case of the tax planning services described below, allow the executive officers to realize
the full benefit of the other elements of compensation we provide. Executive officers are also provided with
one annual physical examination. Executive officers are eligible for four weeks of vacation from date of hire
through ten years of employment, and five weeks of vacation per year thereafter. Additionally, all executive
officers, as well as all other full-time employees, are eligible to receive a one-time additional two week
vacation benefit after ten years of service. In certain cases, the Company may provide relocation expense
reimbursement and related tax gross-up benefits, and tax preparation and planning services, to the executive
officers.

In addition, executive officers are eligible to receive severance benefits in connection with terminations of

employment due to death, disability, or termination without cause or constructive termination (including
following a change-in-control) as set forth below and more fully described in Potential Payments upon
Termination or Change-In-Control. The Board updated the executive severance agreements most recently in
2007 to reflect competitive market standards. In revising the agreements, the Board relied on input provided
by Hewitt and Associates, a third party consultant, which provided a competitive analysis using primarily the
2007 peer group data and Committee recommendations. The Committee believes that the executive severance
arrangements continue to reflect current market standards and severance benefits competitive with those
provided by our peer group. The Committee believes that in order to continue to retain the services of our key
executive officers, it is important to provide them with some income and benefit protection against an
involuntary termination of employment.

Compensation components for executive officers in the event of death include partial stock award
acceleration, prorata bonus payment, payments for accrued base salary, vested deferred compensation, any
accrued vacation and any accrued benefits under any plans of the Company in which the executive officer is a
participant and any appropriate business expenses incurred by the executive officer. In the event of death, there
is no base salary continuation.

Compensation components for executive officers in the event of a qualifying long-term disability include

partial stock award acceleration, prorata bonus payment, limited base salary continuation, payments for
accrued base salary, limited Company-paid health insurance benefits, vested deferred compensation, and any
accrued vacation and any accrued benefits under any plans of the Company in which the executive officer is a
participant.

Compensation components for executive officers in the event of termination by the Company without
cause or termination by the executive officer due to constructive termination include payments for accrued
base salary, cash compensation payments, partial stock award acceleration, limited Company-paid health

34

insurance benefits, vested deferred compensation, and any accrued vacation and any accrued benefits under
any plans of the Company in which the executive officer is a participant. Eligibility for these benefits under
either situation requires a signed release agreement by the executive officer.

Compensation components for executive officers in the event of a termination by the Company without

cause or termination by the executive officer due to constructive termination following a change-in-control
include payments for accrued base salary, a cash compensation payment, cash compensation for the value of
all outstanding stock awards, limited Company-paid health insurance benefits, vested deferred compensation,
and any accrued vacation and any accrued benefits under any plans of the Company in which the executive
officer is a participant. The change-in-control benefits also contain certain tax gross-up provisions. Eligibility
for these benefits requires a signed release agreement by the executive officer.

The compensation committee believes that in order to continue to retain the services of our key executive

officers and focus their efforts on stockholder interests when considering strategic alternatives, it is important
to provide them with enhanced income and benefit protection against loss of employment in connection with a
change-in-control of our company and thereby align the interests of our stockholders and our executive
officers. However, we do not provide for such benefits solely in the event of a change-in-control because we
believe that our executives are materially harmed only if a change in control results in our executives’
involuntary loss of employment, reduced responsibilities, reduced compensation, or other adverse change in
the nature of the employment relationship.

Chief Executive Officer Compensation

In January 2008, Dr. Gorman was promoted to President and Chief Executive Officer and his annualized
base salary became $440,000 reflecting a 10% promotional increase over his 2007 base salary. Dr. Gorman’s
new base salary was established based upon increased responsibilities and significantly similar to the Radford
Survey data. Dr. Gorman’s current base salary is slightly below the median for the 2009 peer group. In
February 2008, Dr. Gorman was awarded a one-time cash payment under the Retention Program in the amount
of $240,000, 60% of which was paid immediately and 40% of which was paid in December 2008. This was
the same payment schedule used in the Retention Program for all non-officer employees. In February 2008,
Dr. Gorman was also awarded 125,000 RSUs and a stock option to purchase 45,000 shares under the Retention
Program that ratably vest on an annual basis over three years. Due to the unmet goal of obtaining a partnership
for our lead program, GnRH, the general downturn in the economy, and the need for the Company to conserve
capital at this time, the Committee recommended, and the Board of Directors approved in January 2009, no
change in Dr Gorman’s base salary for 2009, and no cash bonus or equity awards to Dr. Gorman for 2008
performance.

In January 2008, Mr. Lyons and the Company’s Board of Directors reached mutual agreement that

Mr. Lyons would no longer serve as the President and Chief Executive Officer of the Company, and
Dr. Gorman was appointed President and Chief Executive Officer. For the remainder of the year, Mr. Lyons
was compensated pursuant to the severance provisions in his employment agreement.

Other Executive Officer Compensation

The compensation of all other executive officers is reviewed annually as discussed above. In January 2008,

Dr. O’Brien, Dr. Grigoriadis and Dr. Bozigian became executive officers of the Company.

Base Salary

Effective January 1, 2008, the executive officers’ annualized base salaries became as follows: $300,000

for Mr. Coughlin, $395,000 for Dr. Valeur-Jensen, $375,000 for Dr. O’Brien, and $285,000 for each of
Dr. Grigoriadis and Dr. Bozigian. Mr. Coughlin’s annualized base salary was determined through a combina-
tion of individual performance, initial success in the role of Chief Financial Officer and his prior annualized
base salary being below the Company’s targeted range. Dr. Valeur-Jensen’s annualized base salary was
determined through a combination of individual performance and her prior annualized base salary being near
the top of the Company’s targeted range. Dr. O’Brien’s annualized base salary was determined through a

35

combination of individual performance, additional responsibilities in regulatory affairs and his prior annualized
base salary being near the top of the Company’s targeted range. Both Dr. Bozigian and Dr. Griogriadis’
annualized base salaries were determined through a combination of individual performance and their prior
annualized base salaries being at or below the Company’s targeted range.

Due to the unmet goal of obtaining a partnership for our lead program, GnRH, the general downturn in
the economy, and the desire of the Company to conserve capital at this time, the Committee recommended,
and the Board of Directors approved in January 2009, no change in the executive officers’ base salary for
2009. Executive officer base salaries, as is, are within the peer group compensation parameters described in
the Components of Compensation section above except for Mr. Coughlin, Dr. Grigoriadis and Dr. Bozigian
whose base salaries are slightly below the 50th percentile.

Retention Program

Cash Payments. The Committee established the Retention Program as described in more detail above.
As a result of the Retention Program, each executive officer, other than Dr. Grigoriadis, was awarded a one-
time cash payment under the Retention Program, 60% of which was paid immediately and 40% of which was
paid at the end of 2008, assuming the executive officer remained in good standing as an employee at such
time. This is the same payment schedule was used in the Retention Program for all non-officer employees.
Under the Retention Program, Mr. Coughlin received a total cash award of $138,000, Dr. Valeur-Jensen
received a total cash award of $190,000, Dr. O’Brien received a total cash award of $140,000, and Dr. Bozigian
received a total cash award of $104,000 in each case in accordance with the payment schedule described
above.

Dr. Grigoriadis was not awarded a cash retention payment as the Company had agreed to forgive a loan
to Dr. Grigoriadis which the Committee determined would make his additional participation in the Retention
Program inappropriate. In 2001, the Company and Dr. Grigoriadis entered into a loan agreement pursuant to
which the Company provided a home loan in the principal amount of $230,000 to Dr. Grigoriadis secured by
the real property and Dr. Grigoriadis’ Company stock. Due to the prohibition on loans to executive officers
under the Sarbanes-Oxley Act, prior to his promotion to an executive officer of the Company, Dr. Grigoriadis
was given the option of repaying the loan in full and participating in the Retention Program at the officer level
or foregoing participation in the Retention Program as a result of the forgiveness of the loan. Dr. Grigoriadis
elected to forego participation in the Retention Program and the loan was forgiven prior to his promotion on
January 10, 2008.

Long-Term Incentives. Long-term incentives are awarded to individuals to align the sharing of value

creation between stockholders and executive officers. Long-term incentive awards are also used as a key
retention and motivational tool. In February 2008, the Committee implemented the Retention Program and
awarded the following long-term incentive grants: Dr. Valeur-Jensen, Mr. Coughlin, Dr. O’Brien, Dr. Grigoriadis,
and Dr. Bozigian were each granted 100,000 RSUs and a stock option to purchase 30,000 shares. The Committee
awarded long-term incentives that were within the compensation parameters described in the Components of
Compensation section above. In addition, the mix of the awards was heavily weighted in favor of RSUs over
stock options, which the Committee believes reinforces retention of the executive. These RSUs and stock option
awards vest ratably on an annual basis over three years. The exercise price of the stock options was $5.12 based
on the closing price of the Company’s common stock on the date of grant.

Cash Bonuses and Equity Awards

Due to the unmet goal of obtaining a partnership for our lead program, GnRH, and the desire of the
Company to conserve capital at this time, the Committee recommended, and the Board of Directors approved
in January 2009, no performance cash bonuses or equity awards to any of the executive officers for 2008
performance. Rising or falling stock prices had no bearing on 2008 equity and bonus awards as none were
given.

36

Deferred Compensation Plan

For each year of the NQDC Plan, the Company may, but is not required to, make contributions to any of
the executive officers’ NQDC plan accounts. During 2008, the Company did not make any such contributions.
Two executive officers elected to make voluntary contributions to the NQDC Plan during 2008 as described in
the Nonqualified Deferred Compensation Table below.

Tax Considerations

Internal Revenue Code Section 162(m)

The Committee considers the potential impact under Internal Revenue Code Section 162(m) whereby we
can only deduct up to $1.0 million of the compensation we pay to named executive officers each taxable year
unless such compensation is “performance-based compensation” within the meaning of the Internal Revenue
Code. The Committee has determined that any gain related to the exercise of a stock option granted under any
of our stockholder-approved stock option plans with an exercise price at least equal to the fair value of our
common stock on the date of grant qualifies under the Internal Revenue Code as performance-based
compensation and therefore is not subject to the $1.0 million limitation.

However, deductibility is not the sole factor used by the committee in ascertaining appropriate levels or

manner of compensation and corporate objectives may not necessarily align with the requirements for full
deductibility under Section 162(m). Accordingly, we may enter into executive compensation arrangements
under which payments are not deductible under Section 162(m).

Internal Revenue Code Section 409A

Section 409A of the Internal Revenue Code governs deferred compensation arrangements. The Committee

reviewed our deferred compensation programs with the assistance of our counsel to ensure the programs are
compliant with Section 409A and has determined the programs are compliant within the meaning of Internal
Revenue Code Section 409A.

COMPENSATION COMMITTEE REPORT

The Compensation Committee of the Company has reviewed and discussed the Compensation Discussion

and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and
discussions, the Compensation Committee recommended to the Board of Directors that the Compensation
Discussion and Analysis be included in this Proxy Statement.

Respectfully submitted by:

Wylie W. Vale, Ph.D., who became a member of the Compensation Committee in February 2008. No
interlocking relationship exists between any current member of the Compensation Committee and any member
of any other company’s Board of Directors or compensation committee.

Gary A. Lyons and the Company’s Board of Directors reached a mutual agreement that Mr. Lyons would

no longer serve as the President and Chief Executive Officer of the Company effective January 10, 2008. In
connection with his departure, Mr. Lyons is receiving severance benefits substantially in accordance with
Section 6.5 of his prior employment contract with the Company, which required payment of 2 times the
amount of his annual base salary and target annual bonus to be paid equally over 24 months, an acceleration
of unvested shares that would have vested during the 24 subsequent months after the date of termination, and
payment of COBRA benefits for a period of 24 months following termination. Mr. Lyons continues to serve as
a member of the Board of Directors of the Company.

Option Cancellation Agreements. On October 24, 2007, the Company entered into Stock Option
Cancellation Agreements with certain of the Company’s executive officers and directors, pursuant to which
certain stock options with exercise prices in excess of $50.00, previously granted to each such executive

41

officer or director were cancelled in exchange for a nominal payment by the Company of $100 in the
aggregate.

The Stock Option Cancellation Agreements indicated that other than such nominal payment, the

applicable executive officer or director had not received, and would not receive, any additional consideration
in exchange for the cancellation of such options.

Accordingly, while each such executive officer or director will be eligible to receive future equity grants

in connection with the Company’s regular grant practices, no such executive officer or director will receive
any future equity award in exchange for the cancellation of such options.

GEL Family LLC (6) . . . . . . . . . . .

(1) Stock awards granted to executive officers consist of RSUs and restricted stock, which are subject to deferred delivery
arrangements. The market value of RSUs and restricted stock that have not vested is derived by multiplying the num-
ber of RSUs and restricted stock that have not vested as of December 31, 2008 by $3.20, the closing price of the
Company’s common stock on December 31, 2008.

(2) Vests monthly over four years.

(3) On November 7, 2005, the Company accelerated vesting on all unvested stock options to purchase shares of common
stock that were held by then-current employees and had an exercise price per share equal to or greater than $50.00.
The acceleration of these stock options was undertaken to eliminate the future compensation expense associated with
the adoption of SFAS 123R in the Company’s consolidated statements of operations.

(4) Vests monthly over three years.

(5) Vests annually over three years.

(6) As of December 31, 2008 these options were held by limited liability companies formed by the executive officer

listed immediately above the limited liability company for estate planning purposes.

(7) Vests monthly over four years, subject to an initial one-year “cliff”.

(8) Vests 50% upon FDA approval of indiplon and 50% upon commercialization of indiplon.

43

(9) Options are subject to accelerated vesting provisions based on certain years of service and age upon retirement.

Mr. Lyons satisfied these requirements in April 2007.

(10) Options are subject to accelerated vesting provisions based on severance arrangements.

(11) Options are not subject to accelerated vesting provisions. These options will vest on the 3rd anniversary of the grant

date.

Nonqualified Deferred Compensation. The following table sets forth information regarding the compen-

sation deferred into the Company’s NQDC Plan in the fiscal year ended December 31, 2008 by the Named

(1) Consists of cash contributions from salary and/or bonus payments paid by the Company in 2008.

(2) Aggregate balance includes the value of stock based awards subject to future vesting for all Named Executive

Officers who contributed stock based awards to the NQDC Plan.

Under the terms of the NQDC Plan, executive officers are eligible to defer base salary, bonus and/or
special equity awards, such as RSUs. Generally, elections must be made by December 31 of each preceding
year and are irrevocable once made. Because the Company expects to incur liabilities under the terms of the
NQDC Plan, the Company elected, but was not required to, establish a rabbi trust with the intention to make
contributions to the trust to provide a source of funds to assist in meeting its potential liabilities under the
terms of the NQDC Plan. Upon receipt of an eligible participant’s deferral election, the Company maintains a
bookkeeping account on behalf of such participant. Benefits are paid to participants based on an elected
payout schedule over a period of up to 15 years that may commence on an elected specified date, or if earlier,
upon separation from service. Upon death or termination for cause, funds are paid out within 60 days
following the event. Funds may also be withdrawn for hardship under some circumstances. Executive officers’
accounts under the NQDC Plan are credited with deferrals made by him or her, and are thereafter adjusted to
record earnings and losses matching the performance of various phantom investment options selected by the
executive officer. All cash deferrals are 100% vested upon contribution. All equity award contributions vest
according to the terms of the individual award.

Potential Payments Upon Termination or Change-in-Control. The following tables set forth the potential

severance benefits payable to the Named Executive Officers (excluding Gary A. Lyons, who was no longer
employed by the Company as of December 31, 2008) in the event of a termination prior to or following a
change in control, assuming such event occurred on December 31, 2008. As previously noted in the discussion
that follows the “Nonqualified Deferred Compensation Table,” our Named Executive Officers may receive
payments under our NQDC Plan in the event of termination of employment, based on an elected payout
schedule of up to 15 years. Payout amounts under our NQDC Plan are additional to those set forth in the
following table:

* Reflects a termination without cause or due to a constructive termination, or deemed termination, prior to a

change in control.

(1) Based on salary as of December 31, 2008.

(2) Based on bonus targets established by the Board of Directors for 2008.

(3) Accrued compensation is comprised of vacation pay earned and unpaid as of December 31, 2008 and a one-time

additional two week vacation benefit for eligible employees.

(4) All options held by the Named Executive Officers at December 31, 2008 had an exercise price greater than the

Company’s closing price of its common stock at December 31, 2008. Therefore, using the intrinsic method or
cash value method to calculate the expense associated with accelerating options results in $0 under both

45

calculations. The amounts in this column represent the market value of unvested restricted stock units as of
December 31, 2008 that would vest in accordance with the executive officers’ employment agreements. Restricted
stock unit values were derived using the closing market price on December 31, 2008 of $3.20.

(5) Medical is comprised of health insurance premiums for the period specified in each executive officer’s employ-

ment contract.

material adverse changes in the nature of executive’s employment, as specified in the agreement, that is not
cured following notification:

(cid:129)

(cid:129)

paid equally over 15 months, an acceleration of unvested shares that would have vested over the 15 continuous
months after the date of termination, and payment of COBRA benefits to continue then-current coverage for a
period of 15 months following termination in the event that the Company terminates his employment without

15 months of base salary paid semi-monthly over 15 months, a lump sum amount equal to his target annual
bonus multiplied by a fraction the numerator of which is the number of full months of employment by

her annual base salary and annual target bonus to be paid in one lump sum, a cash amount equal to the value
of all unvested stock awards and all vested and outstanding stock awards, and payment of COBRA benefits to

sum amount equal to her target annual bonus multiplied by a fraction the numerator of which is the number of

Dr. O’Brien for the increase in federal and state income taxes payable by him by reason of the benefits
provided in connection with such a termination in connection with a change in control if the total payment

RELATED PERSON TRANSACTIONS

Review, approval or ratification of related person transactions

In accordance with the Company’s Audit Committee Charter, the Company’s Audit Committee is
responsible for reviewing and approving the terms and conditions of all related person transactions. In
connection with its review, approval or ratification of related person transactions, the Company’s Audit
Committee takes into account all relevant available facts and circumstances in determining whether such
transaction is in the best interests of the Company and its stockholders. Any transaction that would disqualify
a director from meeting the “independent director” standard as defined under the Nasdaq Stock Market rules
requires review by the Company’s audit committee prior to entering into such transaction. For all other related
person transactions the Company reviews all agreements and payments for related person transactions and
based on this review, a report is made to the Company’s audit committee quarterly disclosing all related person
transactions during that quarter, if any. All related person transactions shall be disclosed in the Company’s
applicable filings with the Securities and Exchange Commission as required under SEC rules.

fee of $50,000 in exchange for his consulting services to the Company. The consulting agreement was
terminated in February 2009 and Dr. Vale will thereafter be compensated through regular cash director fees. In
addition, during 2008, the Company paid approximately $425,000 to the Salk Institute, where Dr. Vale is a
professor and head of the Clayton Foundation Laboratories for Peptide Biology, for license and patent
expenses related to our corticotropin-releasing factor programs.

OTHER MATTERS

As of the date of this Proxy Statement, the Company knows of no other matters to be submitted to the
stockholders at the Annual Meeting. If any other matters properly come before the Annual Meeting, it is the
intention of the persons named in the enclosed proxy card to vote the shares they represent as the Board of
Directors may recommend.

ADDITIONAL INFORMATION

“Householding” of Proxy Materials. The Securities and Exchange Commission has adopted rules that

permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements
with respect to two or more stockholders sharing the same address by delivering a single proxy statement
addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially
provides extra convenience for stockholders and cost savings for companies. The Company, and some brokers,
household proxy materials, delivering a single proxy statement to multiple stockholders sharing an address
unless contrary instructions have been received from the affected stockholders. Once you have received notice
from your broker or us that they or we will be householding materials to your address, householding will
continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish
to participate in householding and would prefer to receive a separate proxy statement, please notify your
broker if your shares are held in a brokerage account or us if you hold registered shares.

Advance Notice Procedures. To be considered for inclusion in next year’s proxy materials, a stockholder
must submit his, her or its proposal in writing by December 23, 2009, which is the first business day after the
date that is 120 days prior to the first anniversary of the mailing date of this proxy statement, to the
Company’s Corporate Secretary at 12780 El Camino Real, San Diego, California 92130. Any proposal must
comply with the requirements as to form and substance established by the Securities and Exchange
Commission for such proposal to be included in our proxy statement. Stockholders are also advised to review
our bylaws, which contain additional requirements about advance notice of stockholder proposals and director
nominations.

Products Under Clinical Development

Elagolix — Gonadotropin-Releasing Hormone (GnRH) Antagonist

Gonadotropin-releasing hormone, or GnRH, is a peptide that stimulates the secretion of the pituitary hormones
that are responsible for sex steroid production and normal reproductive function. Researchers have found that
chronic administration of GnRH agonists, after initial stimulation, reversibly shuts down this transmitter pathway

4

and is clinically useful in treating hormone-dependent diseases such as endometriosis, uterine fibroids and benign
prostatic hyperplasia (BPH). Several companies have developed peptide GnRH agonists on this principle, such as
Lupron» and Zoladex», and according to their manufacturers, their annual worldwide sales in 2007 totaled
$3 billion (EvaluatePharma). However, since they are peptides, they must be injected via a depot formulation rather
than the preferred oral route of administration. In addition, GnRH agonists can take up to several weeks to exert
their desired effect once the initial stimulation has occurred, a factor not seen with the use of GnRH antagonists.
More importantly, until the desired effects are maximal, they have shown a tendency to exacerbate the condition via
a hormonal flare. The ultimate profound suppression effect observed with GnRH agonists is similar to that seen
after menopause and can be associated with hot flashes and the loss of bone mineral density.

Orally active, nonpeptide GnRH antagonists potentially offer several advantages over injectable GnRH
peptide drugs, including rapid onset of hormone suppression without a hormonal flare. Also, injection site reactions
commonly observed in peptide depots are avoided and dosing can be rapidly discontinued if necessary — a clinical
management option not available with long-acting depot injections. Importantly, by using GnRH antagonists, it may
be possible to alter the level of pituitary GnRH suppression and thereby titrating circulating estrogen levels. Using
this approach, an oral GnRH antagonist may provide patients relief from the painful symptoms of endometriosis
while avoiding the need for the active management of bone loss.

Endometriosis. Endometriosis is associated with a multitude of symptoms, some of the most common of
which include pain related both to menstruation (dysmenorrhea) and sexual intercourse (dyspareunia) as well as
chronic pelvic pain throughout the menstrual cycle, infertility, and menorrhagia, among many others. The wide
range of symptoms associated with endometriosis serves to complicate and delay diagnosis due to the significant
overlap of symptoms with the disease profiles of other conditions. Datamonitor (2007) estimates that there are
approximately 7.5 million women in the United States who suffer from the symptoms of endometriosis. With
annual healthcare costs and endometriosis-related productivity losses of approximately $4,000 per patient, the
annual direct and indirect costs of endometriosis are estimated to exceed $20 billion in the United States alone
(S Simoens et al Human Reproduction Update 2007, 13 395). We believe that the availability of an oral treatment,
lacking the side effect profile of the currently available peptide GnRH agonists, may be a desirable alternative to
current therapies and ultimately encourage a higher treatment rate.

Several Phase I clinical trials of our lead, orally active nonpeptide GnRH antagonist, elagolix, for endometri-
osis have been completed. These studies demonstrated that elagolix was safe and well tolerated. Dose-dependent
hormonal suppression with once a day elagolix was observed in doses ranging from 50mg and 400mg /day. The
reduction in estradiol has been correlated with a reduction in pain and other symptoms of endometriosis and is a
useful biomarker for safety and efficacy. Based on the results of these Phase I trials, we completed two separate
exploratory three-month Phase IIa trials, during 2006, in endometriosis patients to assess efficacy and tolerability of
elagolix. Efficacy in these Phase II studies was assessed by the Composite Pelvic Sign and Symptoms Score
(CPSSS) and Visual Analog Scale (VAS) industry-standard and validated measures utilized for evaluating pain
reduction in endometriosis patients. In addition to the standard clinical and laboratory assessments of safety, a
biomarker for bone resorption (n-telopeptide) was also measured to assess potential impact on bone mineral density.

The first of the two randomized, placebo controlled Phase IIa three-month trials in patients with endometriosis
involved doses of 75mg and 150mg elagolix given once daily. The second Phase IIa study involved doses of 50mg
and 100mg elagolix given twice daily to more fully explore dose response. Taken together, these trials indicate that a
reduction in pain associated with endometriosis, as measured by CPSSS and VAS, is possible with benefit occurring
within the first two weeks for some women. The magnitude of pain reduction is roughly comparable to that seen
with depo-subQ provera 104TM (DMPA-SC) and Lupron» although direct comparison to these treatments was not
part of these Phase IIa trials. Average estradiol levels were reduced in a dose-related manner and, most importantly,
do not fall into the post-menopausal range associated with GnRH agonist treatments. Furthermore, no increase in
bone resorption was evident as shown by stable mean n-telopeptide levels.

During 2007, we also completed a bridging study comparing elagolix drug formulations (tablets and solutions)
we have used in clinical trials to date to new formulations of tablets. The successful completion of this study allowed
us to select what we anticipate to be our final commercial formulation tablet.

5

During 2008, we completed the dosing and 6-month follow up of a Phase IIb study in which 252 patients, with
a laparoscopic diagnosis of endometriosis, were treated over a 6-month period. This multi-center, randomized,
double-blind, double-dummy study consisted of three treatment groups, elagolix 150mg once a day, elagolix 75mg
twice daily, and an active control, DMPA-SC. The primary purpose of this study was to assess the impact of six
months of treatment of elagolix on bone mineral density as measured by dual energy x-ray absorptiometry (DXA)
scan at the conclusion of treatment and at 6 and 12 months post treatment. This study also assessed, as secondary
endpoints, the impact of treatment on endometriosis symptoms as measured by CPSSS and VAS. Top-line results
were released in September 2008 and showed that elagolix met the primary endpoint by having minimal impact on
bone mineral density at the conclusion of treatment. This study also showed that elagolix had both a statistical and
clinically meaningful reduction in endometriosis symptoms as measured by CPSSS with an 86% responder rate in
the 150mg once daily elagolix arm of the study. This study confirmed our decision to move forward with once daily
dosing as elagolix displayed approximately the same efficacy whether given once or twice daily and a superior
safety profile for bone mineral density. Additional data from this study is expected to be released during 2009 which
will include the DXA scans from both 6 and 12 months post treatment, and various pharmacokinetic and
pharmacodynamic analyses.

We are conducting two additional Phase IIb studies of elagolix to fully explore its dose range, to evaluate
modified endpoints proposed by the U.S. Food and Drug Administration (FDA), and to evaluate elagolix in a
comparator trial with a monthly injection of leuprolide (Prostap» SR). Both of these trials are utilizing our selected
commercial formulation tablet for six months of treatment. These two trials are designed to assess elagolix against
placebo (and Prostap» SR) for an initial three months and after completing three months of treatment the non-
elagolix treatment arms are re-randomized into either 150mg or 250mg of elagolix once daily for an additional three
months.

The first additional Phase IIb trial was fully enrolled as of December 31, 2008 and consists of three arms,
elagolix 150mg once daily, elagolix 250mg once daily, and placebo. We randomized 155 subjects with a
laparoscopic diagnosis of endometriosis in this trial. The initial three month treatment period for this trial
concluded in December 2008 and we expect top-line results in the first quarter of 2009.

The second additional Phase IIb trial is currently enrolling in Central Eastern Europe and consists of four arms,
elagolix 150mg once daily, elagolix 250mg once daily, Prostap» SR 3.75mg, and placebo. We expect to enroll
approximately 180 subjects, with a laparoscopic diagnosis of endometriosis, in this trial. Top-line data from the
initial three month treatment period is expected in the third quarter of 2009.

We expect to have an end of Phase II meeting with the FDA in late 2009, the purpose of which would be to
agree with the FDA on the design of the pivotal Phase III program for elagolix in endometriosis. We expect elagolix
Phase III clinical trials to commence in early 2010.

Benign Prostatic Hyperplasia. BPH is defined by the enlargement of the prostate gland. In BPH, as the
prostate grows larger and presses against the urethra, normal flow of urine is hindered. Researchers have determined
that dihydrotestosterone (DHT), a derivative of testosterone, contributes to prostate enlargement. Equally impor-
tant, men who do not generate DHT do not develop BPH. Accordingly, by using a small molecule GnRH antagonist,
one can suppress the production of testosterone, and indirectly DHT, and potentially ameliorate the symptoms of
BPH. More recent clinical and pre-clinical data indicate that transient suppression of testosterone may trigger a
decrease in the size of the prostate and thereby permit intermittent treatment with a drug such as elagolix without
untoward side effects.

Moderate to severe BPH affects an estimated 20 million men in the United States (UroToday). Additionally,
more than 50% of all men over the age of 50 suffer from the symptoms of BPH (The National Institute of Diabetes &
Kidney Diseases). Worldwide sales of current treatments for BPH exceeded $4 billion in 2007 (EvaluatePharma).
During 2004, we conducted a Phase I single dose study to assess the safety, tolerability, pharmacokinetics and
pharmacodynamics of our GnRH antagonist in healthy males. The results of this trial demonstrated that our GnRH
antagonist effectively reduced testosterone production when compared to placebo. In 2005, we filed an Investi-
gational New Drug application to initiate a multiple dose Phase I study in males. A second study was completed in
2006 and those results demonstrate that a dose-related reduction of testosterone was achieved and that two weeks of
GnRH antagonist treatment is generally safe and well tolerated in healthy males.

Corticotropin-Releasing Factor (CRF) Receptor1 Antagonist

According to Datamonitor (2007), the prevalence of major depressive disorder exceeds 20 million in the
United States alone with an estimated 121 million sufferers worldwide. Estimates based on data from the National
Institute of Mental Health and the U.S. Census Bureau, Population Division also indicate that in 2007 over
20 million Americans suffer from a debilitating anxiety disorder. In 2007, the worldwide branded market for
depression therapeutics was nearly $11 billion (Med Ad News).

Depression. Depression is one of a group of neuropsychiatric disorders that is characterized by extreme
feelings of despair, loss of body weight, decreased aggressiveness and sexual behavior, and loss of sleep.
Researchers believe that depression results from a combination of environmental factors, including stress, as
well as an individual’s biochemical vulnerability, which is genetically predetermined. The most frequently
prescribed antidepressant therapies are drugs that inhibit the reuptake of the neurotransmitters serotonin, nore-
pinephrine and dopamine and include drugs such as Zoloft», Paxil», Lexapro», Prozac», Cymbalta», Pristiq»,
Wellbutrin» and Effexor» as well as certain generic equivalents. These compounds act by inhibiting the reuptake of
neurotransmitters back into presynaptic neurons thus effectively increasing their levels and enhancing activity in the
brain. However, because these drugs affect a wide range of neurotransmitters, they have been associated with a
number of adverse side effects. While newer, more selective drugs offer some safety improvement, side effects
remain problematic. Two of the biggest limitations of most existing antidepressant therapies are their slow onset of
action and their negative effects on libido.

Anxiety. Anxiety is among the most commonly observed group of central nervous system disorders, which
includes phobias or irrational fears, panic attacks, and other syndromes. Of the pharmaceutical agents that other
companies currently market for the treatment of anxiety disorders, benzodiazepines, such as Valium» and Xanax»
and the anxiolytics BuSpar» and Effexor» as well as certain generic equivalents are the most frequently prescribed.
Several side effects, however, limit the utility of these anti-anxiety drugs. Most problematic among these are
drowsiness, memory difficulties, drug dependency and withdrawal reactions following the termination of therapy.

Researchers have identified what they believe to be the central mediator of the body’s stress responses or
stress-induced disorders (including depression and anxiety). This mediator is a brain chemical known as corti-
cotropin-releasing factor, or CRF. CRF is overproduced in clinically depressed patients and may be dysregulated in
individuals with anxiety disorders. Current research indicates that clinically depressed patients and patients with
anxiety experience dysfunction of the hypothalamic-pituitary-adrenal axis, the system that manages the body’s
overall response to stress. This amplifies production of CRF, and induces the physical effects that are associated
with stress that can lead to depression or anxiety. The novelty and specificity of the CRF mechanism of action and
the prospect of improving upon selective serotonin reuptake inhibitor therapy represents a market opportunity both
to better serve patients and expand the overall treatment of depression. We also believe that CRF offers a novel
mechanism of action and the advantage of being more selective, thereby providing increased efficacy with reduced
side effects in anxiety when compared to benzodiazepines.

We have a strategic position in the CRF field through our intellectual property portfolio and relationship with
experts in the neuropsychiatric field. We have further characterized the CRF receptor system and have identified
additional members of the CRF receptor family. We have patent rights on two receptor subtypes termed CRF1 and
CRF2, and we have pending patent applications on small molecule organic compounds modulating the CRF
receptors.

The first clinical trial to offer evidence of proof of concept of CRF antagonists in addressing depression (and
anxiety as a co-examined variable) was a Phase IIa open label trial we conducted in 1999 pursuant to collaborations
with Janssen Pharmaceutica (Janssen) in the field of CRF antagonists. Results from this trial indicated that the drug
candidate was safe and well tolerated and demonstrated anti-depressant activity as measured by a widely-accepted
depression scale known as the Hamilton Depression Scale. In this trial, the drug candidate was administered to
20 patients with major depressive disorder. Results from the trial, as reported in the Journal of Psychiatric Research,
showed that treatment response, as defined by more than a 50% reduction in Hamilton Depression Scores, occurred
in 50% of the patients in the low dose group and 80% of the patients in the higher dose group. Additionally, the drug
candidate demonstrated a reduction in Hamilton Anxiety Scores from baseline in both treatment groups at all times
after dosing. While development of our first generation CRF antagonist was discontinued for safety reasons by our

collaborator Janssen, we were encouraged by these results which we believe support the hypothesized mechanism
of action. Our CRF antagonist research collaboration with Janssen was terminated in March 2002.

In July 2001, we announced our second CRF antagonist collaboration, a worldwide collaboration with
GlaxoSmithKline (GSK), to develop and commercialize CRF antagonists for psychiatric, neurological and
gastrointestinal diseases. Under the terms of this agreement, GSK sponsored and we jointly conducted a research
program and collaborated in the development of our current lead compounds, as well as novel back-up candidates
and second generation compounds identified through the collaborative research. The sponsored research portion of
the collaboration was completed in 2005.

During 2004, GSK advanced one of the lead CRF1 drug candidates arising out of our collaboration into Phase I
clinical trials. The trial was a double-blind, placebo-controlled, single-dose study to evaluate safety and pharma-
cokinetics of a range of escalating doses. This study was followed by the successful completion of a placebo-
controlled double blind multiple dose Phase I study.

GSK has completed a Phase II clinical trial with CRF1 receptor antagonist compound, 876008, for social
anxiety disorder (SocAD). In this double-blind, randomized, placebo controlled, multiple dose study to evaluate the
safety and efficacy of the CRF1 receptor antagonist compound in patients with SocAD, no statistically significant
differences were observed in the key efficacy endpoints between 876008 and placebo at 12 weeks. This study
included more than 200 adult subjects and assessed efficacy, safety, tolerability and pharmacokinetics of the
compound. The compound was generally well tolerated with no serious adverse events reported.

GSK has advanced a second lead CRF1 receptor antagonist compound, 561679, into a Phase II depression
study during 2008. This multicenter randomized, double-blind, placebo-controlled trial is designed to assess the
safety and efficacy of 561679 in approximately 150 subjects with Major Depressive Disorder. Results are expected
in 2010.

GSK has also completed a successful Phase I single dose escalating clinical trial with 586529, an additional

CRF1 receptor antagonist compound.

Irritable Bowel Syndrome. Research has also suggested that CRF plays a role in the control or modulation of
the gastrointestinal system. Studies have demonstrated that central administration of CRF acts to inhibit emptying
of the stomach while stimulating bowel activity, and suggest that overproduction of CRF in the brain may be a main
contributor to stress-related gastrointestinal disorders.

IBS is a gastrointestinal inflammatory disease that affects between 25 to 45 million people in the United States,
accounting for over $20 billion in direct and indirect costs each year, according to the International Foundation for
Functional Gastrointestinal Disorders. IBS can be a lifelong, intermittent disease, involving chronic or recurrent
abdominal pain and frequent diarrhea or constipation. Some patients with IBS report the onset of symptoms of the
disease following a major life stress event, such as death in the family, which suggests that the causes of IBS may be
related to stress. In addition, most IBS sufferers also experience anxiety and depression.

GSK has completed a Phase II clinical trial assessing the CRF1 receptor antagonist compound 876008 in IBS.
In this double-blind, randomized, placebo controlled study to evaluate the safety and efficacy of 876008 in patients
with IBS, no statistically significant differences were observed in the key efficacy endpoints between 876008 and
placebo. Approximately 130 patients meeting established diagnostic criteria for IBS were entered into this cross-
over design trial.

CRF2 Receptor Peptide Agonist (Urocortin 2)

Congestive heart failure (CHF) is a condition where the heart cannot pump enough blood to supply all of the
body’s organs. It is a result of narrowing of the arteries combined with high blood pressure, which results in
increased respiration as well as edema from water retention. In the case of acute symptomology, CHF patients will
eventually experience a rapid deterioration and require urgent treatment in the hospital. According to 2008 data
from the American Heart Association, over 5 million people experience CHF and about 660,000 new cases are
diagnosed each year in the United States. CHF becomes more prevalent with age and the number of cases is
expected to grow as the overall age of the population increases. Current treatment options include a cocktail of drugs

8

consisting of diuretics to remove excess water, beta blockers and digitalis to improve heart muscle contraction,
and/or ACE inhibitors and vasodilators to expand blood vessels. There are in excess of one million hospitalizations
each year in the United States for CHF (AMA 2009).

Urocortin 2 is an endogenous peptide ligand of the CRF2 receptor present in the cardiovascular system, notably
the heart and cerebral arterial system. Urocortin 2 plays a role in the control of the hormonal, cardiovascular,
gastrointestinal, and behavioral responses to stress, and has an array of effects on the cardiovascular system and
metabolism. Based on preclinical efficacy and safety data, together with its known role in human physiology, we
believe that urocortin 2 may have positive hemodynamic effects on cardiac output and blood pressure which may
benefit patients with acute CHF.

During 2005, we completed a Phase II placebo controlled dose-escalation study to evaluate the safety,
pharmacokinetics and pharmacodynamics of two dose levels of urocortin 2 in patients with stable CHF. Results of
this study demonstrated a dose-related increase in cardiac output of up to 50% with only a modest increase (6%) in
heart rate. We completed an additional Phase II study evaluating urocortin 2 over four-hour infusions in patients
with stable CHF in the first half of 2006. The treatments were generally well tolerated without serious adverse
events, abnormalities in electrocardiograms or significant changes in renal function. Positive hemodynamic effects
were noted in virtually all patients with increases in cardiac output ranging from 6% to 54%.

During 2008, we completed the necessary preclinical work to allow for periods of infusion of urocortin 2 up to
14 days. This substantially completes all of the preclinical toxicology work required by the FDA. Further
development of urocortin 2 for CHF and other acute care cardiovascular diseases is highly dependent upon
partnering of this program.

Research Programs

Our research and development focus is on addressing diseases and disorders of the central nervous system and
endocrine system, which include therapeutic categories ranging from diabetes to stress-related disorders and
neurodegenerative diseases. Central nervous system and endocrinology drug therapies are among the largest
therapeutic categories, accounting for over $60 billion in worldwide drug sales in 2007 according to Med Ad News.

Vesicular Monoamine Transporter 2 Inhibitor (VMAT2)

VMAT2 is a protein concentrated in the human brain that is essential for the transmission of nerve impulses
between neurons. VMAT2 is primarily responsible for re-packaging and transporting monamines (dopamine,
norepinephrine, serotonin, and histamine) among nerve cells. Specifically, dopamine enables neurotransmission
among nerve cells that are involved in voluntary and involuntary motor control.

We have identified one highly selective VMAT2 inhibitor that is effective in regulating the levels of dopamine
release during nerve communication, while at the same time having minimal impact on the other monoamines
thereby reducing the likelihood of “off target” side effects. We have developed this novel compound to provide very
predictable plasma and brain concentrations and therefore allow for exposure that we expect to be well tolerated in
patients.

We believe that this clinical candidate will be effective in the management of hyperkinetic movement disorders
characterized by involuntary bodily movements as seen in patients suffering from Tardive Dyskinesia, and
Huntington’s disease. Additionally, the modulation of dopamine pathways may also be useful for patients suffering
from schizophrenia, one population at risk for Tardive Dyskinesia.

We anticipate moving this compound into Phase I clinical trials in 2009.

Glucose Dependent Insulin Secretagogues

Type II diabetes affects more than 23 million Americans (Datamonitor 2007), and is growing at epidemic
proportions world-wide. The disease is characterized by reduced ability to secrete and respond to insulin. Drugs
which can enhance the secretion of insulin in response to rising blood glucose levels can improve blood glucose

9

control without increased risk of hypoglycemia. Our scientists are optimizing small molecule compounds that act in
this way in order to discover novel oral therapies for glucose control in diabetes.

Antiepileptic Drugs

Anticonvulsants are utilized in the treatment of epileptic seizures by suppressing the rapid firing of neurons
that initiate a seizure. Anticonvulsants also have a mood stabilizing effect that has proved beneficial in bipolar
disease. In 2007 anticonvulsants sold approximately $11 billion worldwide (EvaluatePharma, MedAd News).

GnRH Antagonists

As previously mentioned, GnRH antagonists may be useful in treating certain hormone dependent diseases.
Our discovery work in nonpeptide GnRH antagonists continues to focus on endometriosis, uterine fibroids, benign
prostatic hyperplasia and oncology indications as we continue to develop additional candidates for preclinical and
clinical trials.

Programs Subject to Regulatory Review

Indiplon

Indiplon is a non-benzodiazepine GABAA receptor agonist for the treatment of insomnia which acts via the
same mechanism as the currently marketed non-benzodiazepine therapeutics. We obtained the rights to indiplon
through an exclusive worldwide sublicense agreement that we entered into with DOV Pharmaceutical, Inc. (DOV)
in June 1998.

Based on the results of preclinical studies and Phase I, Phase II and Phase III clinical trials on indiplon, as well
as a non-clinical data package related to indiplon manufacturing, formulation and commercial product develop-
ment, we assembled and filed NDAs with the FDA for both indiplon capsules and indiplon tablets. On May 15,
2006, we received two complete responses from the FDA regarding our indiplon capsule and tablet NDAs. These
responses indicated that indiplon 5mg and 10mg capsules were approvable (2006 FDA Approvable Letter) and that
the 15mg tablets were not approvable (FDA Not Approvable Letter).

The FDA Not Approvable Letter for the tablets requested that we reanalyze certain safety and efficacy data and
questioned the sufficiency of the objective sleep maintenance clinical data with the 15mg tablet in view of the fact
that the majority of our indiplon tablet studies were conducted with doses higher than 15mg. We held an
end-of-review meeting with the FDA related to the FDA Not Approvable Letter in October 2006. This meeting
was specifically focused on determining the actions needed to bring indiplon tablets from Not Approvable to
Approval in the resubmission of the NDA for indiplon tablets. The FDA has requested additional long-term safety
and efficacy data with the 15mg dose for the adult population and the development of a separate dose for the elderly
population.

The 2006 FDA Approvable Letter requested that we reanalyze data from certain preclinical and clinical studies
to support approval of indiplon 5mg and 10mg capsules for sleep initiation and middle of the night dosing. The 2006
FDA Approvable Letter also requested reexamination of the safety analyses. We held an end-of-review meeting
with the FDA related to the 2006 FDA Approvable Letter in August 2006. This meeting was specifically focused on
determining the actions needed to bring indiplon capsules from Approvable to Approval in the resubmission of the
NDA for indiplon capsules. At the meeting, the FDA requested that the resubmission include further analyses and
modifications of analyses previously submitted to address questions raised by the FDA in the initial review. This
reanalysis was completed. The FDA also requested, and we completed, a supplemental pharmacokinetic/food effect
profile of indiplon capsules including several meal types.

On June 12, 2007, we resubmitted our NDA for indiplon 5mg and 10mg capsules seeking clearance to market
indiplon capsules for the treatment of insomnia. The FDA accepted the NDA resubmission and established a
Prescription Drug User Fee Act (PDUFA) date of December 12, 2007. On December 12, 2007 we received an action
letter from the FDA stating the indiplon 5mg and 10mg capsules are approvable (2007 FDA Approvable Letter).
The 2007 FDA Approvable Letter acknowledged that the resubmitted NDA had addressed the issues raised in the
2006 FDA Approvable Letter, but set forth new requirements. The new requirements set forth in the 2007 FDA

10

Approvable Letter are the following: (i) an objective/subjective clinical trial in the elderly, (ii) a safety study
assessing the rates of adverse events occurring with indiplon when compared to a marketed product, and (iii) a
preclinical study to evaluate indiplon administration during the third trimester of pregnancy.

In July 2008 we held an end-of-review meeting with the FDA to discuss the 2007 FDA Approvable Letter. We
are currently awaiting the final minutes of this meeting. After receipt of the 2007 FDA Approvable Letter, we ceased
all indiplon clinical development activities in the United States as well as all pre-commercialization activities.

Our Business Strategy

Our goal is to become the leading biopharmaceutical company focused on neurological and endocrine-related

diseases and disorders. The following are the key elements of our business strategy:

Continuing to Advance and Build Our Product Portfolio Focused on Neurological and Endocrine-Related
Diseases and Disorders. We believe that by continuing to advance and build our product pipeline, we can mitigate
some of the clinical development risks associated with drug development. We currently have eight programs in
various stages of research and development, including five programs in clinical development. We take a portfolio
approach to managing our pipeline that balances the size of the market opportunities with clear and defined clinical
and regulatory paths to approval. We do this to ensure that we focus our internal development resources on
innovative therapies with improved probabilities of technical and commercial success.

Identifying Novel Drug Targets to Address Unmet Market Opportunities. We seek to identify and validate
novel drug targets for internal development or collaboration. For example, the novel drug candidates we have
identified to regulate CRF, which is believed to be the central mediator of the body’s stress response, may represent
the first new breakthrough for anxiety and depression in over 25 years. GnRH antagonists, compounds designed to
reduce the secretions of sex steroids, may represent the first novel non-peptide, non-injectible means of treatment of
endometriosis. The creativity and productivity of our discovery research group will continue to be a critical
component for our continued success. Our team has a goal of delivering one innovative clinical compound each year
to fuel our research and development pipeline. Research and development costs were $55.3 million, $82.0 million,
and $97.7 million for the years ended December 31, 2008, 2007 and 2006, respectively.

Selectively Establishing Corporate Collaborations with Global Pharmaceutical Companies to Assist in the
Development of Our Products and Mitigate Financial Risk while Retaining Significant Commercial Upside. We
leverage the development, regulatory and commercialization expertise of our corporate collaborators to accelerate
the development of certain of our potential products, while typically retaining co-promotional rights, and at times
commercial rights, in North America. We intend to further leverage our resources by selectively entering into
additional strategic alliances to enhance our internal development and commercialization capabilities by licensing
our technology.

Acquiring Rights to Complementary Drug Candidates and Technologies. We plan to continue to selectively
acquire rights to products in various stages of development to take advantage of our drug development capabilities.
For example, during 2003, we licensed our urocortin 2 product candidate from the Research Development
Foundation.

Our Corporate Collaborations and Strategic Alliances

One of our business strategies is to utilize strategic alliances to enhance our development and commercial-

ization capabilities. The following is a summary of our significant collaborations/alliances:

GlaxoSmithKline (GSK).

In July 2001, we announced a worldwide collaboration with an affiliate of GSK to
develop and commercialize CRF antagonists for psychiatric, neurological and gastrointestinal diseases. Under the
terms of this agreement, we and GSK will conduct a collaborative research program and collaborate in the
development of our current lead compounds, as well as novel back-up candidates and second generation compounds
identified through the collaborative research. In addition, we will be eligible to receive milestone payments as
compounds progress through the research and development process, royalties on future product sales and
co-promotion rights in the U.S. in some circumstances. GSK may terminate the agreement at its discretion upon
90 days prior written notice to us. In such event, we may be entitled to specified payments and all product rights

11

would revert to us. As of December 31, 2008, we had recorded revenues of $4.5 million in license fees,
$29.8 million in milestone payments, $19.5 million in sponsored research and $1.4 million in reimbursement
of development costs, over the life of the agreement. The sponsored research portion of this collaboration agreement
concluded in 2005.

Dainippon Sumitomo Pharma Co. Ltd. (DSP).

In October 2007, we announced an exclusive license
agreement with DSP to develop and commercialize indiplon in Japan. Under the terms of the agreement DSP
made an up-front payment to us of $20.0 million and is responsible for all future development, marketing and
commercialization costs of indiplon in Japan. We will be eligible to receive additional milestone payments upon
specified future events related to the development and commercialization of indiplon in Japan. Should all
milestones be achieved, we may be entitled to additional payments totaling up to $115.0 million. We are also
entitled to royalties from DSP on future sales of indiplon in Japan. As of December 31, 2008, we had recorded
revenue of $3.4 million in license fees from DSP over the life of the agreement.

Intellectual Property

We seek to protect our lead compounds, compound libraries, expressed proteins, synthetic organic processes,
formulations, assays, cloned targets, screening technology and other technologies by filing, or by causing to be filed
on our behalf, patent applications in the United States and abroad. These applications have resulted in the issuance
of approximately 73 United States patents. Additionally, we have licensed from institutions such as The Salk
Institute, DOV, Research Development Foundation and others the rights to issued United States patents, pending
United States patent applications, and issued and pending foreign filings. We face the risk that one or more of the
above patent applications may be denied. We also face the risk that issued patents that we own or license may be
challenged or circumvented or may otherwise not provide protection for any commercially viable products we
develop.

The technologies we use in our research, as well as the drug targets we select, may infringe the patents or
violate the proprietary rights of third parties. If this occurs, we may be required to obtain licenses to patents or
proprietary rights of others in order to continue with the commercialization of our products.

In addition to the granted and potential patent protection, the United States, the European Union and Japan all
provide data protection for new medicinal compounds. If this protection is available, no competitor may use the
original applicant’s data as the basis of a generic marketing application during the period of data protection. This
period of exclusivity is five years in the United States, six years in Japan and six to ten years in the European Union,
measured from the date of FDA, or corresponding foreign, approval.

Manufacturing and Distribution

We currently rely on, and will continue to rely on, contract manufacturers to produce sufficient quantities of
our product candidates for use in our preclinical and anticipated clinical trials. In addition, we intend to rely on third
parties to manufacture any products that we may commercialize in the future. We have established an internal
pharmaceutical development group to develop manufacturing methods for our product candidates, to optimize
manufacturing processes, and to select and transfer these manufacturing technologies to our suppliers. We continue
to contract with multiple manufacturers to ensure adequate product supply and to mitigate risk.

There currently are a limited number of these manufacturers. Furthermore, some of the contract manufacturers
that we have identified to date only have limited experience at manufacturing, formulating, analyzing and
packaging our product candidates in quantities sufficient for conducting clinical trials or for commercialization.

We currently have no distribution capabilities. In order to independently commercialize any of our product
candidates, we must either internally develop distribution capabilities or make arrangements with third parties to
perform these services.

Marketing and Sales

We currently have limited experience in marketing or selling pharmaceutical products. Under our collab-
oration agreement with GSK we may have the opportunity to co-promote any products resulting from the

12

collaboration in the United States. To market any of our other products independently would require us to develop a
sales force with technical expertise along with establishing commercial infrastructure and capabilities.

Government Regulation

Regulation by government authorities in the United States and foreign countries is a significant factor in the
development, manufacture and marketing of our proposed products and in our ongoing research and product
development activities. All of our products will require regulatory approval by government agencies prior to
commercialization. In particular, human therapeutic products are subject to rigorous preclinical studies and clinical
trials and other approval procedures of the FDA and similar regulatory authorities in foreign countries. Various
federal and state statutes and regulations also govern or influence testing, manufacturing, safety, labeling, storage
and record-keeping related to such products and their marketing. The process of obtaining these approvals and the
subsequent compliance with appropriate federal and state statutes and regulations require the expenditure of
substantial time and financial resources.

Preclinical studies generally are conducted in laboratory animals to evaluate the potential safety and the
efficacy of a product. Drug developers submit the results of preclinical studies to the FDA as a part of an IND
application that must be approved before clinical trials can begin in humans. Typically, clinical evaluation involves
a time consuming and costly three-phase process.

Phase I

Clinical trials are conducted with a small number of patients to determine the early safety profile,
maximum tolerated dose and pharmacological properties of the product in human volunteers.

Phase II Clinical trials are conducted with groups of patients afflicted with a specific disease in order to
determine preliminary efficacy, optimal dosages and expanded evidence of safety.

Phase III Large-scale, multi-center, comparative clinical trials are conducted with patients afflicted with a

specific disease in order to determine safety and efficacy as primary support for regulatory
approval by the FDA to market a product candidate for a specific disease.

The FDA closely monitors the progress of each of the three phases of clinical trials that are conducted in the
United States and may, at its discretion, reevaluate, alter, suspend or terminate the testing based upon the data
accumulated to that point and the FDA’s assessment of the risk/benefit ratio to the patient. To date, we have also
conducted some of our clinical trials in Europe, Oceania, and South Africa. Clinical trials conducted in foreign
countries may also be subject to oversight by regulatory authorities in those countries.

Once Phase III trials are completed, drug developers submit the results of preclinical studies and clinical trials
to the FDA in the form of an NDA or a biologics licensing application for approval to commence commercial sales.
In response, the FDA may grant marketing approval, request additional information or deny the application if the
FDA determines that the application does not meet regulatory approval criteria. FDA approvals may not be granted
on a timely basis, or at all. Furthermore, the FDA may prevent a drug developer from marketing a product under a
label for its desired indications, which may impair commercialization of the product.

If the FDA approves the NDA, the drug becomes available for physicians to prescribe in the United States.
After approval, the drug developer must submit periodic reports to the FDA, including descriptions of any adverse
reactions reported. The FDA may request additional studies, known as Phase IV, to evaluate long-term effects. The
FDA may also require a Risk Evaluation and Mitigation Strategy (REMS) safety plan upon approval.

In addition to studies requested by the FDA after approval, a drug developer may conduct other trials and
studies to explore use of the approved compound for treatment of new indications. The purpose of these trials and
studies and related publications is to broaden the application and use of the drug and its acceptance in the medical
community.

We will also have to complete an approval process similar to that in the United States in virtually every foreign
target market for our products in order to commercialize our product candidates in those countries. The approval
procedure and the time required for approval vary from country to country and may involve additional testing.
Foreign approvals may not be granted on a timely basis, or at all. In addition, regulatory approval of prices is
required in most countries other than the United States. The resulting prices may not be sufficient to generate an
acceptable return to us or our corporate collaborators.

13

Competition

The biotechnology and pharmaceutical industries are subject to rapid and intense technological change. We
face, and will continue to face, competition in the development and marketing of our product candidates from
biotechnology and pharmaceutical companies, research institutions, government agencies and academic institu-
tions. Competition may also arise from, among other things:

(cid:129) other drug development technologies;

(cid:129) methods of preventing or reducing the incidence of disease, including vaccines; and

(cid:129) new small molecule or other classes of therapeutic agents.

Developments by others may render our product candidates or technologies obsolete or noncompetitive. We
are performing research on or developing products for the treatment of several disorders including endometriosis,
anxiety, depression, pain, diabetes, irritable bowel syndrome, insomnia, and other neurological and endocrine
related diseases and disorders.

Lupron Depot», marketed by TAP Pharmaceuticals, and Synarel» and Depo-Provera», marketed by Pfizer, are
gonadotropin-releasing hormone peptide agonists that have been approved for the treatment of endometriosis,
infertility, and central precocious puberty. Additionally, Proscar», an enzyme inhibitor marketed by Merck, and
Flomax», an alpha blocker marketed by Boehringer Ingelheim Pharmaceuticals, are both used in the treatment of
benign prostatic hyperplasia. These drugs may compete with any small molecule gonadotropin-releasing hormone
antagonists we develop for these indications.

Potential indications for our small molecule CRF antagonists include anxiety disorders, depression, and
irritable bowel syndrome, among others, our drug candidates will be commercialized in well-established markets.
In the area of anxiety disorders, our product candidates will compete with products such as Valium», marketed by
Hoffman-La Roche, Xanax», marketed by Pfizer, BuSpar», marketed by Bristol-Myers Squibb, Zoloft», marketed
by Pfizer, Wellbutrin», marketed by GSK and Effexor», marketed by Wyeth, among others, as well as any generic
alternatives for each of these products.

In the area of depression, our product candidates will compete with products in the antidepressant class,
including Prozac» and Cymbalta», marketed by Eli Lilly, Zoloft», marketed by Pfizer, Paxil», marketed by GSK,
Effexor», marketed by Wyeth, and Lexapro», marketed by Forest Laboratories, among others.

In the area of irritable bowel syndrome, our product candidates will compete with such products as Lotronex»
marketed by Prometheus Laboratories Inc. in the United States. Some technologies under development by other
pharmaceutical companies could result in additional commercial treatments for depression and anxiety. In addition,
a number of companies also are conducting research on molecules to block CRF, which is the same mechanism of
action employed by our compounds.

In the area of insomnia, Ambien», Sonata», Lunesta», and Rozerem» are currently marketed by Sanofi-
Aventis, King Pharmaceuticals, Inc., Sepracor, Inc., and Takeda Pharmaceutical Company, respectively. During
2006, Sanofi-Aventis launched a controlled-release formulation of Ambien» called Ambien CR» and during 2007,
generic Ambien» or zolpidem also entered the insomnia market. Somaxon Pharmaceuticals is developing Silenor»,
a H1 antagonist, for the treatment of insomnia, which has completed Phase III clinical trials and for which the
PDUFA date is in February 2009.

In the area of schizophrenia, our product candidates will compete with such products as Geodon», marketed by
Pfizer, Zyprexa», marketed by Eli Lilly, Risperdal», marketed by Janssen, and Seroquel», marketed by AstraZe-
neca, among others.

If one or more of these products or programs are successful, it may reduce or eliminate the market for our

products.

14

Compared to us, many of our competitors and potential competitors have substantially greater:

(cid:129) capital resources;

(cid:129) research and development resources, including personnel and technology;

(cid:129) regulatory experience;

(cid:129) preclinical study and clinical testing experience;

(cid:129) manufacturing and marketing experience; and

(cid:129) production facilities.

Any of these competitive factors could harm our business, prospects, financial condition and results of

operations, which could negatively affect our stock price.

Employees

As of January 31, 2009, we had approximately 125 employees, of which 38 hold Ph.D., M.D. or equivalent
degrees. None of our employees are represented by a collective bargaining arrangement, and we believe our
relationship with our employees is good. Recruiting and retaining qualified scientific personnel to perform research
and development work in the future will be critical to our success. We may not be able to attract and retain personnel
on acceptable terms given the competition among biotechnology, pharmaceutical and health care companies,
universities and non-profit research institutions for experienced scientists. In addition, we rely on a number of
consultants to assist us in formulating our research and development strategies.

Insurance

We maintain product liability insurance for our clinical trials. We intend to expand our insurance coverage to
include the sale of commercial products if marketing approval is obtained for products in development. However,
insurance coverage is becoming increasingly expensive, and we may not be able to maintain insurance coverage at a
reasonable cost or in sufficient amounts to protect us against losses due to liability. In addition, we may not be able
to obtain commercially reasonable product liability insurance for any products approved for marketing.

Available Information

Our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and
amendments to reports filed pursuant to Sections 13(a) and 15(d) of the Securities Exchange Act of 1934, as
amended, are available on our website at www.neurocrine.com, when such reports are available on the Securities
and Exchange Commission website at www.sec.gov.

Additionally, copies of our annual report will be made available, free of charge, upon written request.

ITEM 1A. RISK FACTORS

The following information sets forth risk factors that could cause our actual results to differ materially from
those contained in forward-looking statements we have made in this Annual Report on Form 10-K and those we
may make from time to time. If any of the following risks actually occur, our business, operating results, prospects
or financial condition could be harmed. Additional risks not presently known to us, or that we currently deem
immaterial, may also affect our business operations.

Risks Related to Our Company

We depend on continuing our current collaborations and developing additional collaborations to develop
and commercialize our product candidates.

Our strategy for fully developing and commercializing our products is dependent upon maintaining our current
arrangements and establishing new arrangements with research collaborators, corporate collaborators and others,
particularly as it relates to our GnRH and urocortin 2 programs. We have active collaboration agreements with
GlaxoSmithKline and Dainippon Sumitomo Pharma Co. Ltd. and previously have had collaborations with Pfizer,

15

Wyeth, Johnson & Johnson, Novartis, Taisho and Eli Lilly and Company. We historically have been dependent upon
these corporate collaborators to provide adequate funding for a number of our programs. Under these arrangements,
our corporate collaborators are typically responsible for:

(cid:129) selecting compounds for subsequent development as drug candidates;

(cid:129) conducting preclinical studies and clinical trials and obtaining required regulatory approvals for these drug

candidates; and

(cid:129) manufacturing and commercializing any resulting drugs.

Because we expect to continue to rely heavily on corporate collaborators, the development and commer-
cialization of our programs would be substantially delayed if one or more of our current or future collaborators:

(cid:129) failed to select a compound that we have discovered for subsequent development into marketable products;

(cid:129) failed to gain the requisite regulatory approvals of these products;

(cid:129) did not successfully commercialize products that we originate;

(cid:129) did not conduct its collaborative activities in a timely manner;

(cid:129) did not devote sufficient time and resources to our partnered programs or potential products;

(cid:129) terminated its alliance with us;

(cid:129) developed, either alone or with others, products that may compete with our products;

(cid:129) disputed our respective allocations of rights to any products or technology developed during our

collaborations; or

(cid:129) merged with a third party that wants to terminate the collaboration.

These issues and possible disagreements with current or future corporate collaborators could lead to delays in
the collaborative research, development or commercialization of many of our product candidates. Furthermore,
disagreements with these parties could require or result in litigation or arbitration, which would be time-consuming
and expensive. If any of these issues arise, it may delay the development and commercialization of drug candidates
and, ultimately, our generation of product revenues.

Our clinical trials may fail to demonstrate the safety and efficacy of our product candidates, which could
prevent or significantly delay their regulatory approval.

Before obtaining regulatory approval for the sale of any of our potential products, we must subject these
product candidates to extensive preclinical and clinical testing to demonstrate their safety and efficacy for humans.
Clinical trials are expensive, time-consuming and may take years to complete.

In connection with the clinical trials of our product candidates, we face the risks that:

(cid:129) the product candidate may not prove to be effective;

(cid:129) we may discover that a product candidate may cause harmful side effects;

(cid:129) the results may not replicate the results of earlier, smaller trials;

(cid:129) we or the FDA or similar foreign regulatory authorities may suspend the trials;

(cid:129) the results may not be statistically significant;

(cid:129) patient recruitment may be slower than expected;

(cid:129) patients may drop out of the trials; and

(cid:129) regulatory requirements may change.

For example, there is uncertainty regarding future development of indiplon as described below under the risk
factor entitled “There is uncertainty regarding future development of our product candidate, indiplon, and we may
not be able to meet the requirements to receive regulatory approvals for it.”

In addition, late stage clinical trials are often conducted with patients having the most advanced stages of
disease. During the course of treatment, these patients can die or suffer other adverse medical effects for reasons that
may not be related to the pharmaceutical agent being tested but which can nevertheless adversely affect clinical trial
results. Any failure or substantial delay in completing clinical trials for our product candidates may severely harm
our business.

If we cannot raise additional funding, we may be unable to complete development of our product
candidates.

We may require additional funding to continue our research and product development programs, to conduct
preclinical studies and clinical trials, for operating expenses and to pursue regulatory approvals for product
candidates, for the costs involved in filing and prosecuting patent application and enforcing or defending patent
claims, if any, as well as costs associated with litigation matters, product in-licensing and any possible acquisitions,
and we may require additional funding to establish manufacturing and marketing capabilities in the future. We
believe that our existing capital resources, together with investment income, and future payments due under our
strategic alliances, will be sufficient to satisfy our current and projected funding requirements for at least the next
12 months. However, these resources might be insufficient to conduct research and development programs as
planned. If we cannot obtain adequate funds, we may be required to curtail significantly one or more of our research
and development programs or obtain funds through additional arrangements with corporate collaborators or others
that may require us to relinquish rights to some of our technologies or product candidates.

Our future capital requirements will depend on many factors, including:

(cid:129) continued scientific progress in our research and development programs;

(cid:129) the magnitude of our research and development programs;

(cid:129) progress with preclinical testing and clinical trials;

(cid:129) the time and costs involved in obtaining regulatory approvals;

(cid:129) the costs involved in filing and pursuing patent applications and enforcing patent claims;

(cid:129) competing technological and market developments;

(cid:129) the establishment of additional strategic alliances;

(cid:129) the cost of commercialization activities and arrangements,

including manufacturing of our product

candidates; and

(cid:129) the cost of product in-licensing and any possible acquisitions.

We intend to seek additional funding through strategic alliances, and may seek additional funding through
public or private sales of our securities, including equity securities. For example, we have an effective shelf
registration statement on file with the Securities and Exchange Commission which allows us to issue shares of our
common stock from time to time for an aggregate initial offering price of up to $150 million. In addition, we have
previously financed capital purchases and may continue to pursue opportunities to obtain additional debt financing
in the future. Recently, the credit markets and the financial services industry have been experiencing a period of
unprecedented turmoil and upheaval characterized by the bankruptcy, failure, collapse or sale of various financial
institutions and an unprecedented level of intervention from the United States federal government. These events
have generally made equity and debt financing more difficult to obtain. Accordingly, additional equity or debt
financing might not be available on reasonable terms, if at all. Any additional equity financings will be dilutive to
our stockholders and any additional debt financings may involve operating covenants that restrict our business.

17

Our restructuring activities could result in management distractions, operational disruptions and other
difficulties.

As a result of the uncertainty in the future development of indiplon capsules and tablets, we initiated
restructuring activities in an effort to reduce operating costs, including a work force reduction announced in
December 2007. Employees whose positions were eliminated in connection with this reduction may seek future
employment with our competitors. Although all employees are required to sign a confidentiality agreement with us
at the time of hire, we cannot assure you that the confidential nature of our proprietary information will be
maintained in the course of such future employment. We also entered into a December 2008 amendment to our
facilities lease, under which our landlord will seek to enter into leases with replacement tenants for portions of the
front building of our corporate headquarters, thereby reducing our rent under the lease. Our landlord may not be
successful in entering into leases with replacement tenants on favorable terms, or at all. Any additional restructuring
efforts could divert the attention of our management away from our operations, harm our reputation and increase
our expenses. We cannot assure you that we will not undertake additional restructuring activities, that any of our
restructuring efforts will be successful, or that we will be able to realize the cost savings and other anticipated
benefits from our previous or future restructuring plans. In addition, if we continue to reduce our workforce, it may
adversely impact our ability to respond rapidly to any new growth opportunities.

There is uncertainty regarding future development of our product candidate, indiplon, and we may not be
able to meet the requirements to receive regulatory approvals for it.

On December 12, 2007 we received an action letter from the FDA stating that indiplon 5mg and 10mg capsules
are approvable (2007 FDA Approvable Letter). The 2007 FDA Approvable Letter acknowledged that our
resubmitted NDA for indiplon 5mg and 10mg capsules had addressed the issues raised in a previous approvable
letter, but set forth new requirements. The new requirements set forth in the 2007 FDA Approvable Letter are the
following: (i) an objective/subjective clinical trial in the elderly, (ii) a safety study assessing the rates of adverse
events occurring with indiplon when compared to a marketed product and (iii) a preclinical study to evaluate
indiplon administration during the third trimester of pregnancy. After receipt of the 2007 FDA Approvable Letter,
we ceased all indiplon clinical development activities in the United States as well as all pre-commercialization
activities. We met with the FDA in July 2008 to discuss the 2007 FDA Approvable Letter and we are awaiting the
finalization of the written minutes of this meeting from the FDA.

The process of preparing and resubmitting the NDA for indiplon would require significant resources and could
be time consuming and subject to unanticipated delays and cost. As a result of the 2007 FDA Approvable Letter,
there is a significant amount of uncertainty regarding the future development of indiplon. Should the NDA be
refiled, the FDA could again refuse to approve the NDA, or could still require additional data analysis or clinical
trials, which would require substantial expenditures by us and would further delay the approval process. Even if our
indiplon NDA is approved, the FDA may determine that our data do not support elements of the labeling we have
requested. In such a case, the labeling actually granted by the FDA could limit the commercial success of the
product. The FDA could also require Phase IV, or post-marketing, trials to study the long-term effects of indiplon
and could withdraw its approval based on the results of those trials. The FDA could require a Risk Evaluation and
Mitigation Strategy (REMS) program for indiplon that could limit the commercial success of the product. We face
the risk that for any of the reasons described above, as well as other reasons set forth herein, indiplon may never be
approved by the FDA or commercialized anywhere in the world.

If we determine that it is impractical or we are unable to refile the NDA, or the FDA refuses to accept or
approve the resubmitted NDA for any reason or we experience a further delay in approval and subsequent
commercialization of indiplon, our business and reputation may be harmed and our stock price could decline.

We have a history of losses and expect to incur losses and negative operating cash flows for the near
future, and we may never achieve sustained profitability.

Since our inception, we have incurred significant net losses, including net losses of $88.6 million and
$207.3 million for the years ended December 31, 2008 and 2007, respectively. As a result of ongoing operating

18

losses, we had an accumulated deficit of $703.3 million and $614.7 million as of December 31, 2008 and 2007,
respectively. We do not expect to be profitable for the year ending December 31, 2009 or the foreseeable future.

We have not yet obtained regulatory approvals of any products and, consequently, have not generated revenues
from the sale of products. Even if we succeed in developing and commercializing one or more of our drugs, we may
not be profitable. We also expect to continue to incur significant operating and capital expenditures as we:

(cid:129) seek regulatory approvals for our product candidates;

(cid:129) develop, formulate, manufacture and commercialize our drugs;

(cid:129) in-license or acquire new product development opportunities;

(cid:129) implement additional internal systems and infrastructure; and

(cid:129) hire additional clinical, scientific and marketing personnel.

We also expect to experience negative cash flow for the near future as we fund our operating losses,
in-licensing or acquisition opportunities, and capital expenditures. We will need to generate significant revenues to
achieve and maintain profitability and positive cash flow. We may not be able to generate these revenues, and we
may never achieve profitability in the future. Our failure to achieve or maintain profitability could negatively impact
the market price of our common stock. Even if we become profitable, we cannot assure you that we would be able to
sustain or increase profitability on a quarterly or annual basis.

Because our operating results may vary significantly in future periods, our stock price may decline.

Our quarterly revenues, expenses and operating results have fluctuated in the past and are likely to fluctuate
significantly in the future. Our revenues are unpredictable and may fluctuate, among other reasons, due to our
achievement of product development objectives and milestones, clinical trial enrollment and expenses, research and
development expenses and the timing and nature of contract manufacturing and contract research payments. A high
portion of our costs are predetermined on an annual basis, due in part to our significant research and development
costs. Thus, small declines in revenue could disproportionately affect operating results in a quarter. Because of these
factors, our operating results in one or more future quarters may fail to meet the expectations of securities analysts
or investors, which could cause our stock price to decline.

We license some of our core technologies and drug candidates from third parties. If we default on any of
our obligations under those licenses, we could lose our rights to those technologies and drug candidates.

We are dependent on licenses from third parties for some of our key technologies. These licenses typically
subject us to various commercialization, reporting and other obligations. If we fail to comply with these obligations,
we could lose important rights. For example, we have licensed indiplon from DOV Pharmaceutical, Inc. (DOV). In
addition, we license some of the core technologies used in our collaborations from third parties, including the CRF
receptor we license from The Salk Institute and use in our CRF1 program, and urocortin 2 which we license from
Research Development Foundation. Other in-licensed technologies, such as the GnRH receptor we license from
Mount Sinai School of Medicine, will be important for future collaborations for our elagolix program. If we were to
default on our obligations under any of our licenses, we could lose some or all of our rights to develop, market and
sell products covered by these licenses. Likewise, if we were to lose our rights under a license to use proprietary
research tools, it could adversely affect our existing collaborations or adversely affect our ability to form new
collaborations. We also face the risk that our licensors could, for a number of reasons, lose patent protection or lose
their rights to the technologies we have licensed, thereby impairing or extinguishing our rights under our licenses
with them.

Because the development of our product candidates is subject to a substantial degree of technological
uncertainty, we may not succeed in developing any of our product candidates.

All of our product candidates are in research, clinical development or in registration with the FDA. Only a
small number of research and development programs ultimately result in commercially successful drugs. Potential

19

products that appear to be promising at early stages of development may not reach the market for a number of
reasons. These reasons include the possibilities that the potential products may:

(cid:129) be found ineffective or cause harmful side effects during preclinical studies or clinical trials;

(cid:129) fail to receive necessary regulatory approvals on a timely basis or at all;

(cid:129) be precluded from commercialization by proprietary rights of third parties;

(cid:129) be difficult to manufacture on a large scale; or

(cid:129) be uneconomical to commercialize or fail to achieve market acceptance.

If any of our products encounters any of these potential problems, we may never successfully market that

product.

We have limited marketing experience, sales force or distribution capabilities, and if our products are
approved, we may not be able to commercialize them successfully.

Although we do not currently have any marketable products, our ability to produce revenues ultimately
depends on our ability to sell our products if and when they are approved by the FDA. We currently have limited
experience in marketing and selling pharmaceutical products. If we fail to establish successful marketing and sales
capabilities or fail to enter into successful marketing arrangements with third parties, our product revenues will
suffer.

The independent clinical investigators and contract research organizations that we rely upon to conduct
our clinical trials may not be diligent, careful or timely, and may make mistakes, in the conduct of our
trials.

We depend on independent clinical investigators and contract research organizations (CROs) to conduct our
clinical trials under their agreements with us. The investigators are not our employees, and we cannot control the
amount or timing of resources that they devote to our programs. If independent investigators fail to devote sufficient
time and resources to our drug development programs, or if their performance is substandard, it may delay or
prevent the approval of our FDA applications and our introduction of new drugs. The CROs we contract with for
execution of our clinical trials play a significant role in the conduct of the trials and the subsequent collection and
analysis of data. Failure of the CROs to meet their obligations could adversely affect clinical development of our
products. Moreover, these independent investigators and CROs may also have relationships with other commercial
entities, some of which may compete with us. If independent investigators and CROs assist our competitors at our
expense, it could harm our competitive position.

We have no manufacturing capabilities. If third-party manufacturers of our product candidates fail to
devote sufficient time and resources to our concerns, or if their performance is substandard, our clinical
trials and product introductions may be delayed and our costs may rise.

We have in the past utilized, and intend to continue to utilize, third-party manufacturers to produce the drug
compounds we use in our clinical trials and for the potential commercialization of our future products. We have no
experience in manufacturing products for commercial purposes and do not currently have any manufacturing facilities.
Consequently, we depend on, and will continue to depend on, several contract manufacturers for all production of
products for development and commercial purposes. If we are unable to obtain or retain third-party manufacturers, we
will not be able to develop or commercialize our products. The manufacture of our products for clinical trials and
commercial purposes is subject to specific FDA regulations. Our third-party manufacturers might not comply with FDA
regulations relating to manufacturing our products for clinical trials and commercial purposes or other regulatory
requirements now or in the future. Our reliance on contract manufacturers also exposes us to the following risks:

(cid:129) contract manufacturers may encounter difficulties in achieving volume production, quality control and
quality assurance, and also may experience shortages in qualified personnel. As a result, our contract
manufacturers might not be able to meet our clinical schedules or adequately manufacture our products in
commercial quantities when required;

20

(cid:129) switching manufacturers may be difficult because the number of potential manufacturers is limited. It may
be difficult or impossible for us to find a replacement manufacturer quickly on acceptable terms, or at all;

(cid:129) our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing

business for the time required to successfully produce, store or distribute our products; and

(cid:129) drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, the DEA, and other
agencies to ensure strict compliance with good manufacturing practices and other government regulations
and corresponding foreign standards. We do not have control over third-party manufacturers’ compliance
with these regulations and standards.

Our current dependence upon third parties for the manufacture of our products may harm our profit margin, if
any, on the sale of our future products and our ability to develop and deliver products on a timely and competitive
basis.

If we are unable to retain and recruit qualified scientists or if any of our key senior executives
discontinues his or her employment with us, it may delay our development efforts.

We are highly dependent on the principal members of our management and scientific staff. The loss of any of
these people could impede the achievement of our development objectives. Furthermore, recruiting and retaining
qualified scientific personnel to perform research and development work in the future is critical to our success. We
may be unable to attract and retain personnel on acceptable terms given the competition among biotechnology,
pharmaceutical and health care companies, universities and non-profit research institutions for experienced
scientists. In addition, we rely on a significant number of consultants to assist us in formulating our research
and development strategy. All of our consultants are employed by employers other than us. They may have
commitments to, or advisory or consulting agreements with, other entities that may limit their availability to us.

We may be subject to claims that we or our employees have wrongfully used or disclosed alleged trade
secrets of their former employers.

As is commonplace in the biotechnology industry, we employ individuals who were previously employed at
other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although no
claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently
or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation
may be necessary to defend against these claims. Even if we are successful in defending against these claims,
litigation could result in substantial costs and be a distraction to management.

Governmental and third-party payors may impose sales and pharmaceutical pricing controls on our
products that could limit our product revenues and delay profitability.

The continuing efforts of government and third-party payors to contain or reduce the costs of health care
through various means may reduce our potential revenues. These payors’ efforts could decrease the price that we
receive for any products we may develop and sell in the future. In addition, third-party insurance coverage may not
be available to patients for any products we develop. If government and third-party payors do not provide adequate
coverage and reimbursement levels for our products, or if price controls are enacted, our product revenues will
suffer.

If physicians and patients do not accept our products, we may not recover our investment.

The commercial success of our products, if they are approved for marketing, will depend upon the acceptance

of our products as safe and effective by the medical community and patients.

The market acceptance of our products could be affected by a number of factors, including:

(cid:129) the timing of receipt of marketing approvals;

(cid:129) the safety and efficacy of the products;

21

(cid:129) the success of existing products addressing our target markets or the emergence of equivalent or superior

products; and

(cid:129) the cost-effectiveness of the products.

In addition, market acceptance depends on the effectiveness of our marketing strategy, and, to date, we have
very limited sales and marketing experience or capabilities. If the medical community and patients do not ultimately
accept our products as being safe, effective, superior and/or cost-effective, we may not recover our investment.

Compliance with changing regulation of corporate governance and public disclosure may result in
additional expenses.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the
Sarbanes-Oxley Act of 2002, new SEC regulations and Nasdaq rules, are creating uncertainty for companies such as
ours. These laws, regulations and standards are subject to varying interpretations in many cases due to their lack of
specificity, and as a result, their application in practice may evolve over time as new guidance is provided by
regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and
higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to
maintaining high standards of corporate governance and public disclosure. As a result, our efforts to comply with
evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased general and
administrative expenses and management time related to compliance activities. In particular, our efforts to comply
with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding our required assessment of
our internal controls over financial reporting requires the commitment of significant financial and managerial
resources. We expect these efforts to require the continued commitment of significant resources. If we fail to comply
with these laws, regulations and standards, our reputation may be harmed and we might be subject to sanctions or
investigation by regulatory authorities, such as the Securities and Exchange Commission. Any such action could
adversely affect our financial results and the market price of our common stock.

The price of our common stock is volatile.

The market prices for securities of biotechnology and pharmaceutical companies historically have been highly
volatile, and the market has from time to time experienced significant price and volume fluctuations that are
unrelated to the operating performance of particular companies. Over the course of the last 12 months, the price of
our common stock has ranged from approximately $2 per share to approximately $6 per share. The market price of
our common stock may fluctuate in response to many factors, including:

(cid:129) the results of our clinical trials;

(cid:129) developments concerning our strategic alliance agreements;

(cid:129) announcements of technological innovations or new therapeutic products by us or others;

(cid:129) general economic and market conditions;

(cid:129) developments in patent or other proprietary rights;

(cid:129) developments related to the FDA approval process for indiplon;

(cid:129) future sales of our common stock by existing stockholders;

(cid:129) comments by securities analysts;

(cid:129) fluctuations in our operating results;

(cid:129) government regulation;

(cid:129) health care reimbursement;

(cid:129) failure of any of our product candidates, if approved, to achieve commercial success; and

(cid:129) public concern as to the safety of our drugs.

22

Negative conditions in the global credit markets may impair the liquidity of a portion of our investment
portfolio.

Our investment securities consist of auction rate securities, corporate debt securities and government agency
securities. As of December 31, 2008, our long-term investments included (at par value) $22.6 million of high-grade
(AAA rated) auction rate securities issued by student loan providers. All of these auction rate securities have
experienced failed auctions due to lack of liquidity at the time their interest rates were to reset. The recent negative
conditions in the global credit markets have prevented some investors from liquidating their holdings, including
their holdings of auction rate securities. As a result, certain of these types of securities are not fully liquid and we
could be required to hold them until they are redeemed by the issuer, a future auction for these securities is
successful, another secondary market evolves for these securities, or they mature. In the event we need to access the
funds that are in an illiquid state, we may not be able to do so without a potential loss of principal. As of
December 31, 2008, the carrying value of all auction rate securities had been reduced by $3.9 million, from
$22.6 million to $18.7 million, reflecting an estimated change in fair market value due primarily to a lack of
liquidity. Although the auction rate securities continue to pay interest according to their stated terms, based on
valuation models, we have recorded a unrealized loss for an other-than-temporary change in valuation of
$3.9 million. If the credit ratings of the security issuers deteriorate or if uncertainties in these markets continue
and any decline in market value is determined to be other-than-temporary, we would be required to adjust the
carrying value of the investment through an impairment charge, which could negatively affect our financial
condition, cash flow and reported earnings.

Risks Related to Our Industry

We may not receive regulatory approvals for our product candidates or approvals may be delayed.

Regulation by government authorities in the United States and foreign countries is a significant factor in the
development, manufacture and marketing of our proposed products and in our ongoing research and product
development activities. Any failure to receive the regulatory approvals necessary to commercialize our product
candidates would harm our business. The process of obtaining these approvals and the subsequent compliance with
federal and state statutes and regulations require spending substantial time and financial resources. If we fail or our
collaborators or licensees fail to obtain or maintain, or encounter delays in obtaining or maintaining, regulatory
approvals, it could adversely affect the marketing of any products we develop, our ability to receive product or
royalty revenues, our recovery of prepaid royalties, and our liquidity and capital resources. All of our products are in
research and development, and we have not yet received regulatory approval to commercialize any product from the
FDA or any other regulatory body. In addition, we have limited experience in filing and pursuing applications
necessary to gain regulatory approvals, which may impede our ability to obtain such approvals.

In particular, human therapeutic products are subject to rigorous preclinical testing and clinical trials and other
approval procedures of the FDA and similar regulatory authorities in foreign countries. The FDA regulates, among
other things, the development, testing, manufacture, safety, efficacy, record keeping, labeling, storage, approval,
advertising, promotion, sale and distribution of biopharmaceutical products. Securing FDA approval requires the
submission of extensive preclinical and clinical data and supporting information to the FDA for each indication to
establish the product candidate’s safety and efficacy. The approval process may take many years to complete and
may involve ongoing requirements for post-marketing studies. Any FDA or other regulatory approval of our product
candidates, once obtained, may be withdrawn. If our potential products are marketed abroad, they will also be
subject to extensive regulation by foreign governments.

We face intense competition, and if we are unable to compete effectively, the demand for our products, if
any, may be reduced.

The biotechnology and pharmaceutical industries are subject to rapid and intense technological change. We
face, and will continue to face, competition in the development and marketing of our product candidates from
academic institutions, government agencies,
research institutions and biotechnology and pharmaceutical
companies.

23

Competition may also arise from, among other things:

(cid:129) other drug development technologies;

(cid:129) methods of preventing or reducing the incidence of disease, including vaccines; and

(cid:129) new small molecule or other classes of therapeutic agents.

Developments by others may render our product candidates or technologies obsolete or noncompetitive.

We are performing research on or developing products for the treatment of several disorders including
endometriosis, anxiety, depression, pain, diabetes, irritable bowel syndrome, insomnia, and other neurological and
endocrine related diseases and disorders, and there are a number of competitors to products in our research pipeline.
If one or more of our competitors’ products or programs are successful, the market for our products may be reduced
or eliminated.

Compared to us, many of our competitors and potential competitors have substantially greater:

(cid:129) capital resources;

(cid:129) research and development resources, including personnel and technology;

(cid:129) regulatory experience;

(cid:129) preclinical study and clinical testing experience;

(cid:129) manufacturing and marketing experience; and

(cid:129) production facilities.

If we are unable to protect our intellectual property, our competitors could develop and market products
based on our discoveries, which may reduce demand for our products.

Our success will depend on our ability to, among other things:

(cid:129) obtain patent protection for our products;

(cid:129) preserve our trade secrets;

(cid:129) prevent third parties from infringing upon our proprietary rights; and

(cid:129) operate without infringing upon the proprietary rights of others, both in the United States and internationally.

Because of the substantial length of time and expense associated with bringing new products through the
development and regulatory approval processes in order to reach the marketplace, the pharmaceutical industry
places considerable importance on obtaining patent and trade secret protection for new technologies, products and
processes. Accordingly, we intend to seek patent protection for our proprietary technology and compounds.
However, we face the risk that we may not obtain any of these patents and that the breadth of claims we obtain, if
any, may not provide adequate protection of our proprietary technology or compounds.

We also rely upon unpatented trade secrets and improvements, unpatented know-how and continuing
technological innovation to develop and maintain our competitive position, which we seek to protect, in part,
through confidentiality agreements with our commercial collaborators, employees and consultants. We also have
invention or patent assignment agreements with our employees and some, but not all, of our commercial
collaborators and consultants. However, if our employees, commercial collaborators or consultants breach these
agreements, we may not have adequate remedies for any such breach, and our trade secrets may otherwise become
known or independently discovered by our competitors.

In addition, although we own a number of patents, the issuance of a patent is not conclusive as to its validity or
enforceability, and third parties may challenge the validity or enforceability of our patents. We cannot assure you
how much protection, if any, will be given to our patents if we attempt to enforce them and they are challenged in
court or in other proceedings. It is possible that a competitor may successfully challenge our patents or that
challenges will result in limitations of their coverage. Moreover, competitors may infringe our patents or

24

successfully avoid them through design innovation. To prevent infringement or unauthorized use, we may need to
file infringement claims, which are expensive and time-consuming. In addition, in an infringement proceeding a
court may decide that a patent of ours is not valid or is unenforceable, or may refuse to stop the other party from
using the technology at issue on the grounds that our patents do not cover its technology. Interference proceedings
declared by the United States Patent and Trademark Office (USPTO) may be necessary to determine the priority of
inventions with respect to our patent applications or those of our licensors. Litigation or interference proceedings
may fail and, even if successful, may result in substantial costs and be a distraction to management. We cannot
assure you that we will be able to prevent misappropriation of our proprietary rights, particularly in countries where
the laws may not protect such rights as fully as in the United States.

The technologies we use in our research as well as the drug targets we select may infringe the patents or
violate the proprietary rights of third parties.

We cannot assure you that third parties will not assert patent or other intellectual property infringement claims
against us or our collaborators with respect to technologies used in potential products. If a patent infringement suit
were brought against us or our collaborators, we or our collaborators could be forced to stop or delay developing,
manufacturing or selling potential products that are claimed to infringe a third party’s intellectual property unless
that party grants us or our collaborators rights to use its intellectual property. In such cases, we could be required to
obtain licenses to patents or proprietary rights of others in order to continue to commercialize our products.
However, we may not be able to obtain any licenses required under any patents or proprietary rights of third parties
on acceptable terms, or at all. Even if our collaborators or we were able to obtain rights to the third party’s
intellectual property, these rights may be non-exclusive, thereby giving our competitors access to the same
intellectual property. Ultimately, we may be unable to commercialize some of our potential products or may have to
cease some of our business operations as a result of patent infringement claims, which could severely harm our
business.

We face potential product liability exposure far in excess of our limited insurance coverage.

The use of any of our potential products in clinical trials, and the sale of any approved products, may expose us
to liability claims. These claims might be made directly by consumers, health care providers, pharmaceutical
companies or others selling our products. We have obtained limited product liability insurance coverage for our
clinical trials in the amount of $10 million per occurrence and $10 million in the aggregate. However, our insurance
may not reimburse us or may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover,
insurance coverage is becoming increasingly expensive, and we may not be able to maintain insurance coverage at a
reasonable cost or in sufficient amounts to protect us against losses due to liability. We intend to expand our
insurance coverage to include the sale of commercial products if we obtain marketing approval for product
candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for
any products approved for marketing. On occasion, juries have awarded large judgments in class action lawsuits
based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought
against us would decrease our cash reserves and could cause our stock price to fall.

Our activities involve hazardous materials, and we may be liable for any resulting contamination or
injuries.

Our research activities involve the controlled use of hazardous materials. We cannot eliminate the risk of
accidental contamination or injury from these materials. If an accident occurs, a court may hold us liable for any
resulting damages, which may harm our results of operations and cause us to use a substantial portion of our cash
reserves, which would force us to seek additional financing.

ITEM 2. PROPERTIES

We lease our two building facility which has approximately 200,000 square feet of laboratory and office space
in San Diego, California. We sold our facility and associated real property for $109.0 million in a sale leaseback
transaction in December 2007 and entered into a twelve year lease with the purchaser. In December 2008, we
entered into an amendment to the lease to provide for the renovation of the front building of our facility in a manner
that facilitates multiple tenant usage and establishes a mechanism for us to terminate our use of the front building.
We are obligated to reimburse the landlord for the total cost of renovating the front building so that it becomes
suitable for multiple tenant usage. We and the landlord will work together in good faith to use commercially
reasonable efforts to keep the cost of the renovation from exceeding $5.5 million. The landlord will seek to enter
into leases with replacement tenants for portions of the front building, which would result in pro rata reductions of
our rent under the lease. In each such instance, we would pay the landlord a rent release fee as well as all applicable
tenant improvement costs and leasing commissions. The amendment also terminated our prior right to repurchase
the facility and associated real property. We believe that our property and equipment are generally well maintained
and in good operating condition.

ITEM 3. LEGAL PROCEEDINGS

On June 19, 2007, Construction Laborers Pension Trust of Greater St. Louis filed a purported class action
lawsuit in the United States District Court for the Southern District of California under the caption Construction
Laborers Pension Trust of Greater St. Louis v. Neurocrine Biosciences, Inc., et al., 07-cv-1111-IEG-RBB. On
June 26, 2007, a second purported class action lawsuit with similar allegations was also filed. On October 16, 2007,
both lawsuits were consolidated into one purported class action under the caption In re Neurocrine Biosciences, Inc.
Securities Litigation, 07-cv-1111-IEG-RBB. The court also selected lead plaintiffs and ordered them to file a
consolidated complaint. On November 30, 2007, lead plaintiffs filed the Consolidated Amended Complaint (CAC),
which alleged, among other things, that we and certain of our officers and directors violated federal securities laws
by making allegedly false and misleading statements regarding the progress toward FDA approval and the potential
for market success of indiplon in the 15 mg dosage unit. On January 11, 2008, we and the individual defendants filed
a motion to dismiss the CAC. Following a hearing on April 22, 2008, the court granted the motion to dismiss but
gave the lead plaintiffs leave to file a second amended complaint. On June 11, 2008, the lead plaintiffs filed the
Second Consolidated Amended Complaint (SAC). On July 8, 2008, we and the individual defendants filed a motion
to dismiss the SAC. The court granted the motion to dismiss on September 23, 2008 but gave lead plaintiffs further
leave to file a Third Consolidated Amended Complaint (TAC). On October 23, 2008, rather than filing a TAC, the
lead plaintiffs filed a Notice of Election to Stand on the SAC, requesting that the court enter a final judgment
dismissing the matter. On November 3, 2008, the court entered a final judgment dismissing the matter with
prejudice. On December 31, 2008, the time elapsed for lead plaintiffs to appeal the court’s final judgment to the
Ninth Circuit Court of Appeals.

In addition, on June 25, 2007, a shareholder derivative complaint was filed in the Superior Court of the State of
California for the County of San Diego by Ralph Lipeles under the caption, Lipeles v. Lyons. The complaint was
brought purportedly on our behalf against certain current and former officers and directors and alleges, among other
things, that the named officers and directors breached their fiduciary duties by directing us to make allegedly false
statements about the progress toward FDA approval and the potential for market success of indiplon in the 15mg
dosage unit. All proceedings in this matter were stayed pending resolution of the motion to dismiss the federal class
action lawsuit. Following the dismissal of the federal class action lawsuit, on November 19, 2008, the plaintiff in the
derivative action filed a request for dismissal of the derivative action. The court entered an order dismissing the
derivative action without prejudice on November 20, 2008.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations
section contains forward-looking statements pertaining to, among other things, the expected continuation of our
collaborative agreements, the receipt of research and development payments thereunder, the future achievement of
various milestones in product development and the receipt of payments related thereto, the potential receipt of
royalty payments, pre-clinical testing and clinical trials of potential products, the period of time that our existing
capital resources will meet our funding requirements, and our financial results of operations. Our actual results
could differ materially from those anticipated in these forward-looking statements as a result of various risks and
uncertainties, including those set forth in this Annual Report on Form 10-K under the heading “Item 1A. Risk
Factors.” See “Forward-Looking Statements” in Part I of this Annual Report on Form 10-K.

Overview

We discover, develop and intend to commercialize drugs for the treatment of neurological and endocrine-
related diseases and disorders. Our product candidates address some of the largest pharmaceutical markets in the
world, including endometriosis, anxiety, depression, pain, diabetes, irritable bowel syndrome, insomnia, and other
neurological and endocrine related diseases and disorders. To date, we have not generated any revenues from the
sale of products. We have funded our operations primarily through private and public offerings of our common stock
and payments received under research and development agreements. We are developing certain products with
corporate collaborators and intend to rely on existing and future collaborators to meet funding requirements. We
expect to generate future net losses due to increases in operating expenses as product candidates are advanced
through the various stages of clinical development. As of December 31, 2008, we had an accumulated deficit of
$703.3 million and expect to incur operating losses in the near future, which may be greater than losses in prior
years. We currently have eight programs in various stages of research and development, including five programs in
clinical development. While we independently develop many of our product candidates, we are in a collaboration
for two of our programs.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations is based upon financial
statements that we have prepared in accordance with accounting principles generally accepted in the United States.
The preparation of these financial statements requires management to make estimates and judgments that affect the
reported amounts of assets, liabilities and expenses, and related disclosures. On an on-going basis, we evaluate these
estimates, including those related to revenues under collaborative research agreements and grants, clinical trial
accruals (research and development expense), debt, share-based compensation, investments, and fixed assets.
Estimates are based on historical experience, information received from third parties and on various other
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Actual results may differ from these estimates under different assumptions or conditions. The items in our financial
statements requiring significant estimates and judgments are as follows:

Revenue Recognition

Revenues under collaborative research and development agreements are recognized as costs are incurred over
the period specified in the related agreement or as the services are performed. These agreements are on a best-efforts
basis, and do not require scientific achievement as a performance obligation, and provide for payment to be made
when costs are incurred or the services are performed. All fees are nonrefundable to the collaborators. Upfront,
nonrefundable payments for license fees and advance payments for sponsored research revenues received in excess
of amounts earned are classified as deferred revenue and recognized as income over the contract or development
period. Estimating the duration of the development period includes continual assessment of development stages and
regulatory requirements. Milestone payments are recognized as revenue upon achievement of pre-defined scientific
events, which requires substantive effort, and for which achievement of the milestone was not readily assured at the

29

inception of the agreement. Revenues from grants are recognized based on a percentage-of-completion basis as the
related costs are incurred.

Clinical Trial Costs

Research and development (R&D) expenses include related salaries, contractor fees, facilities costs, admin-
istrative expenses and allocations of corporate costs. All such costs are charged to R&D expense as incurred. These
expenses result from our independent R&D efforts as well as efforts associated with collaborations, grants and
in-licensing arrangements. In addition, we fund R&D and clinical trials at other companies and research institutions
under agreements, which are generally cancelable. We review and accrue clinical trials expense based on work
performed, which relies on estimates of total costs incurred based on patient enrollment, completion of studies and
other events. We follow this method since reasonably dependable estimates of the costs applicable to various stages
of a research agreement or clinical trial can be made. Accrued clinical costs are subject to revisions as trials progress
to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become
known. Historically, revisions have not resulted in material changes to R&D costs, however a modification in the
protocol of a clinical trial or cancellation of a trial could result in a charge to our results of operations.

Share Based Payments

We grant stock options to purchase our common stock to our employees and directors under our 2003 Incentive
Stock Plan (the 2003 Plan) and grant stock options to certain employees pursuant to Employment Commencement
Nonstatutory Stock Option Agreements. We also grant certain employees stock bonuses and restricted stock units
under the 2003 Plan. Additionally, we have outstanding options that were granted under option plans from which we
no longer make grants. The benefits provided under all of these plans are subject to the provisions of revised
Statement of Financial Accounting Standards (SFAS) 123 (SFAS 123R), “Share-Based Payment,” which we
adopted effective January 1, 2006. We elected to use the modified prospective application in adopting SFAS 123R
and therefore have not restated results for periods prior to its adoption. The valuation provisions of SFAS 123R
apply to new awards and to awards that are outstanding on the adoption date and subsequently modified or
cancelled. Our results of operations for fiscal 2008 were impacted by the recognition of non-cash expense related to
the fair value of our share-based compensation awards. Share-based compensation expense recognized under
SFAS 123R for the years ended December 31, 2008, 2007 and 2006 was $8.0 million, $10.0 million and
$14.4 million, respectively.

Stock option awards and restricted stock units generally vest over a three to four year period and expense is
ratably recognized over those same time periods. However, due to certain retirement provisions in our stock plans,
share-based compensation expense may be recognized over a shorter period of time, and in some cases the entire
share-based compensation expense may be recognized upon grant of the share-based compensation award.
Employees who are age 55 or older and have five or more years of service with us are entitled to accelerated
vesting of certain unvested share-based compensation awards upon retirement. This retirement provision leads to
variability in the quarterly expense amounts recognized under SFAS 123R, and therefore individual share-based
compensation awards may impact earnings disproportionately in any individual fiscal quarter.

The determination of fair value of stock-based payment awards on the date of grant using the Black-Scholes
model is affected by our stock price, as well as the input of other subjective assumptions. These assumptions
include, but are not limited to, the expected term of stock options and our expected stock price volatility over the
term of the awards. Our stock options have characteristics significantly different from those of traded options, and
changes in the assumptions can materially affect the fair value estimates.

SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent
periods if actual forfeitures differ from those estimates. If actual forfeitures vary from our estimates, we will
recognize the difference in compensation expense in the period the actual forfeitures occur or when options vest.

Real Estate

In December 2007, we closed the sale of our facility and associated real property for a purchase price of
$109.0 million. Concurrent with the sale we retired the entire $47.7 million in mortgage debt previously outstanding

30

with respect to the facility and associated real property, and received cash of $61.0 million net of transaction costs
and debt retirement. Upon the closing of the sale of the facility and associated real property, we entered into a lease
agreement whereby we leased back the facility for an initial term of 12 years pursuant to which we lease our
corporate headquarters comprised of two buildings.

Under the terms of the lease, we pay a base annual rent of $7.6 million (subject to an annual fixed percentage
increase, as set forth in the agreement), plus a 3.5% annual management fee, property taxes and other normal and
necessary expenses associated with the lease such as utilities, repairs and maintenance, etc. In lieu of a cash security
deposit under the lease agreement, Wells Fargo Bank, N.A. issued on our behalf a letter of credit in the amount of
$5.7 million. The letter of credit is secured by a deposit of $6.4 million with the same bank. We have the right to
extend the lease for two consecutive ten-year terms and will have the first right of refusal to lease, at market rates,
any facilities built on the sold vacant lot. Additionally, we had a repurchase right to all of the properties which could
have been exercised during the fourth year of the lease.

In accordance with SFAS 98, “Accounting for Leases: Sale-Leaseback Transactions Involving Real Estate,
Sales-Type Leases of Real Estate, Definition of the Lease Term, and Initial Direct Costs of Direct Financing
Leases” (SFAS 98) and SFAS 66, “Accounting for Sales of Real Estate” (SFAS 66) at the close of the transaction, we
initially deferred the gain on the sale of the building and related vacant parcel due to the repurchase right. We also
established a long-term liability of $108.7 million, essentially the gross proceeds from the real estate sale, and
continued to carry the conveyed real estate assets on our balance sheet as of December 31, 2007.

Effective December 10, 2008, we entered into a first amendment to the lease. The lease amendment provides
for the renovation of the front building in a manner that facilitates multiple tenant usage and establishes a
mechanism for us to terminate our use of the front building. We continue to occupy the rear building.

Pursuant to the terms of the lease amendment, we are obligated to reimburse the landlord for the total cost of
renovating a portion of the front building such that the front building becomes suitable for multiple tenant usage. We
and the landlord will work in good faith to use commercially reasonable efforts to keep the total cost of the
renovation from exceeding $5.5 million. We made a one-time payment of $1.0 million toward renovation costs in
January 2009. We will reimburse the landlord for the balance of the renovation costs over a four year period through
an increase in monthly rental payments (currently estimated at $108,000 per month) which began in October 2008.
Furthermore, the lease amendment provides that the landlord shall seek to enter into leases with replacement tenants
for portions of the front building. In connection with each replacement lease, we shall be granted a pro rata
reduction in rent under the lease. We are required to pay all tenant improvement costs, lease termination costs and
leasing commissions in connection with each replacement lease.

The lease amendment also terminated our right to repurchase any portion of the facility or real property. As a
result of the termination of the repurchase right, during the fourth quarter of 2008, we removed from our balance
sheet the long-term liability of $108.7 million and the related previously conveyed real estate assets of $69.6 million.
Additionally, we began to recognize the deferred gain of $39.1 million on the sale of the real estate in accordance
with SFAS 66 and SFAS 98. During 2008, we recognized $3.5 million of the deferred gain and will recognize the
balance of the deferred gain over the remaining lease term.

As a result of signing the lease amendment and physically vacating the front building we triggered a cease-use
date for the front building and have estimated lease termination costs in accordance with SFAS 146, “Accounting for
Costs Associated with Exit or Disposal Activities” (SFAS 146). Estimated lease termination costs for the front
building include the net present value of future minimum lease payments, taxes, insurance, construction, and
maintenance costs from the cease-use date to the end of the remaining lease term net of estimated sublease rental
income. During the fourth quarter of 2008, we recorded an expense of $15.7 million for the net present value of
these estimated lease termination costs, of which $0.3 million was paid in 2008. Additionally, certain other costs
such as leasing commissions and legal fees will be expensed by us as incurred in conjunction with the sublease of
the vacated office space.

31

Asset Impairment

In accordance with SFAS 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,”
(SFAS 144) if indicators of impairment exist, we assess the recoverability of the affected long-lived assets by
determining whether the carrying value of such assets can be recovered through undiscounted future operating cash
flows. If impairment is indicated, we measure the amount of such impairment by comparing the carrying value of
the asset to the estimated fair value of the related asset, which is generally determined based on the present value of
the expected future cash flows.

During the fourth quarter of 2007, we recognized a non-cash impairment charge to earnings related to the
impairment of a prepaid royalty. This prepaid royalty arose out of our acquisition, in February 2004, of Wyeth’s
financial interest in indiplon for approximately $95.0 million, consisting of $50.0 million in cash and $45.0 million
in our common stock. This transaction decreased our overall royalty obligation on sales of indiplon from six percent
to three and one-half percent. The receipt of the 2007 FDA Approvable Letter in December 2007 raised a significant
amount of uncertainty regarding future development of indiplon. Based on this significant uncertainty, we
determined that the prepaid royalty was impaired, and that a non-cash charge of $94.0 million related to this
impairment was required under SFAS 144.

Our revenues for the year ended December 31, 2008 were $4.0 million compared with $1.2 million in 2007.
This increase in revenues was primarily due to revenue recognized in 2008 under our collaboration agreements with
DSP and GSK. License fees revenue recognized under our DSP agreement was $2.9 million in 2008. Additionally,
during 2008, we recognized a $1.0 million milestone payment under our GSK collaboration agreement related to
clinical advancements of our CRF program. During 2007, we entered into an exclusive licensing agreement with
DSP for indiplon in Japan, under which we recognized $0.5 million in revenue, as well as $0.5 million in revenue
related to the out-licensing of our IL-4 program.

Our revenues for the year ended December 31, 2007 were $1.2 million compared with $39.2 million in 2006.
This decrease in revenues was primarily due to revenue recognized in 2006 under our former collaboration
agreement with Pfizer which was terminated in June 2006. License fees, sponsored development revenue and sales
force allowance revenue recognized under our Pfizer agreement were $6.5 million, $6.6 million and $16.5 million,
respectively, in 2006. Additionally, during 2006, we recognized $9.0 million in milestones under our GSK
collaboration agreement. The 2006 milestones recognized under the GSK agreement related to clinical advance-
ments and initiation of two Phase II clinical trials for generalized social anxiety disorder and irritable bowel
syndrome in our CRF program. During 2007, we entered into an exclusive licensing agreement with DSP for
indiplon in Japan, under which we recognized $0.5 million in revenue.

Research and development expenses decreased to $55.3 million during 2008 compared to $82.0 million in
2007. The $26.7 million decrease in research and development expenses was primarily due to cost savings related to
our staff reductions in 2007. The decrease in research and development staff levels reduced personnel costs by

32

$15.2 million (44%) in 2008 compared to 2007. External development costs decreased by $5.1 million to
$19.2 million in 2008 compared to $24.3 million in 2007. External development costs related to our Pro Drugs
and urocortin 2 programs increased by $1.5 million and $1.2 million, respectively, in 2008 compared to 2007.
External development costs related to our subsequently halted indiplon and valnoctamide programs included
expenses of $6.3 million during 2007. Additionally, laboratory costs decreased by $2.2 million during 2008
compared to 2007, primarily due to the staff reductions mentioned above. We currently have eight programs in
various stages of research and development, including five programs in clinical development.

Research and development expenses decreased to $82.0 million during 2007 compared to $97.7 million in
2006. The $15.7 million decrease in research and development expenses was primarily due to cost savings related to
our staff reductions in 2006. The decrease in research and development staff levels reduced personnel costs by
$9.2 million (21%) in 2007 compared to 2006. External development costs decreased by $3.0 million to
$24.3 million in 2007 compared to $27.3 million in 2006. External development costs for our GnRH clinical
program increased to $16.7 million in 2007 compared to $11.1 million during 2006. External development costs
related to our urocortin 2 and sNRI programs decreased by $2.3 million and $1.7 million, respectively, in 2007
compared to 2006. External development costs related to our subsequently cancelled APL and H1 programs
included expenses of $6.6 million during 2006. Additionally, laboratory costs decreased by $2.6 million during
2007 compared to 2006, primarily due to the staff reductions mentioned above.

We expect research and development expenses to decrease during 2009 compared to 2008, primarily due to

cost savings efforts, and the winding down of the Phase II program for elagolix.

Sales, general and administrative expenses decreased to $20.2 million in 2008 compared to $37.5 million
during 2007 and $54.9 million during 2006. The $17.3 million decrease in expenses from 2007 to 2008 resulted
primarily from staff reductions in 2007 and costs for pre-commercialization activities related to indiplon in 2007.
The $17.4 million decrease in expenses from 2006 to 2007 resulted primarily from the severance program enacted
in 2006, offset partially by increased costs for pre-commercialization activities related to indiplon.

We expect sales, general and administrative expenses to decrease during 2009 primarily due to the cost savings

efforts, and the dismissal of the shareholder lawsuits during the fourth quarter of 2008.

During 2008, we recognized $15.7 million in cease-use expense under SFAS 146, related to the front building

of our corporate headquarters and the amendment of our facilities lease as discussed above.

During 2007, we recognized a $94.0 million non-cash impairment charge to earnings under SFAS 144 related

to the impairment of a prepaid royalty as discussed above.

Other (expense) income decreased to $(1.3) million in 2008 compared with $4.9 million during 2007. Other
income was $6.1 million during 2006. The decrease from 2007 to 2008 resulted primarily from rent payments of
$7.0 million made under our facilities sale-leaseback agreement that are recorded as interest expense in accordance
with SFAS 98. Additionally, investment income for 2008 was lower than in the prior year period, primarily due to
lower cash balances coupled with lower overall interest rates. Additionally, during 2008, we recognized $3.5 million
in gains on sale of assets under SFAS 66 and SFAS 98 related to the real estate transaction discussed above. The
decrease in other income from 2006 to 2007 was due to lower investment income due to lower average investment
balances.

Our net loss for 2008 was $88.6 million, or $2.30 per share, compared to $207.3 million, or $5.45 per share, in
2007 and $107.2 million, or $2.84 per share, in 2006. The decrease in net loss from 2007 to 2008 was primarily due
to the impairment charge of $94.0 million in 2007 and cost savings in 2008 related to the staff reductions in 2007.
The increase in net loss from 2006 to 2007 was due primarily to the impairment charge of $94.0 million in 2007.

Litigation matters. On June 19, 2007, Construction Laborers Pension Trust of Greater St. Louis filed a
purported class action lawsuit in the United States District Court for the Southern District of California under the
caption Construction Laborers Pension Trust of Greater St. Louis v. Neurocrine Biosciences, Inc., et al.,
07-cv-1111-IEG-RBB. On June 26, 2007, a second purported class action lawsuit with similar allegations was
also filed. On October 16, 2007, both lawsuits were consolidated into one purported class action under the caption In

33

re Neurocrine Biosciences, Inc. Securities Litigation, 07-cv-1111-IEG-RBB. The court also selected lead plaintiffs
and ordered them to file a consolidated complaint. On November 30, 2007, lead plaintiffs filed the Consolidated
Amended Complaint (CAC), which alleged, among other things, that we and certain of our officers and directors
violated federal securities laws by making allegedly false and misleading statements regarding the progress toward
FDA approval and the potential for market success of indiplon in the 15 mg dosage unit. On January 11, 2008, we
and the individual defendants filed a motion to dismiss the CAC. Following a hearing on April 22, 2008, the court
granted the motion to dismiss but gave the lead plaintiffs leave to file a second amended complaint. On June 11,
2008, the lead plaintiffs filed the Second Consolidated Amended Complaint (SAC). On July 8, 2008, we and the
individual defendants filed a motion to dismiss the SAC. The court granted the motion to dismiss on September 23,
2008 but gave lead plaintiffs further leave to file a Third Consolidated Amended Complaint (TAC). On October 23,
2008, rather than filing a TAC, the lead plaintiffs filed a Notice of Election to Stand on the SAC, requesting that the
court enter a final judgment dismissing the matter. On November 3, 2008, the court entered a final judgment
dismissing the matter with prejudice. On December 31, 2008, the time elapsed for lead plaintiffs to appeal the
court’s final judgment to the Ninth Circuit Court of Appeals.

In addition, on June 25, 2007, a shareholder derivative complaint was filed in the Superior Court of the State of
California for the County of San Diego by Ralph Lipeles under the caption, Lipeles v. Lyons. The complaint was
brought purportedly on our behalf against certain current and former officers and directors and alleges, among other
things, that the named officers and directors breached their fiduciary duties by directing us to make allegedly false
statements about the progress toward FDA approval and the potential for market success of indiplon in the 15mg
dosage unit. All proceedings in this matter were stayed pending resolution of the motion to dismiss the federal class
action lawsuit. Following the dismissal of the federal class action lawsuit, on November 19, 2008, the plaintiff in the
derivative action filed a request for dismissal of the derivative action. The court entered an order dismissing the
derivative action without prejudice on November 20, 2008.

Indiplon developments. Based on the results of preclinical studies and Phase I, Phase II and Phase III clinical
trials on indiplon, as well as a non-clinical data package related to indiplon manufacturing, formulation and
commercial product development, we assembled and filed NDAs with the FDA for both indiplon capsules and
indiplon tablets. On May 15, 2006, we received two complete responses from the FDA regarding our indiplon
capsule and tablet NDAs. These responses indicated that indiplon 5mg and 10mg capsules were approvable (2006
FDA Approvable Letter) and that the 15mg tablets were not approvable (FDA Not Approvable Letter).

The FDA Not Approvable Letter for the tablets requested that we reanalyze certain safety and efficacy data and
questioned the sufficiency of the objective sleep maintenance clinical data with the 15mg tablet in view of the fact
that the majority of our indiplon tablet studies were conducted with doses higher than 15mg. We held an end-of-
review meeting with the FDA related to the FDA Not Approvable Letter in October 2006. This meeting was
specifically focused on determining the actions needed to bring indiplon tablets from Not Approvable to Approval
in the resubmission of the NDA for indiplon tablets. The FDA has requested additional long-term safety and
efficacy data with the 15mg dose for the adult population and the development of a separate dose for the elderly
population. In discussions, we and the FDA noted positive efficacy data for sleep maintenance with both indiplon
capsules and tablets. The evaluation of indiplon for sleep maintenance includes both indiplon capsules and tablets.

The 2006 FDA Approvable Letter requested that we reanalyze data from certain preclinical and clinical studies
to support approval of indiplon 5mg and 10mg capsules for sleep initiation and middle of the night dosing. The 2006
FDA Approvable Letter also requested reexamination of the safety analyses. We held an end-of-review meeting
with the FDA related to the 2006 FDA Approvable Letter in August 2006. This meeting was specifically focused on
determining the actions needed to bring indiplon capsules from Approvable to Approval in the resubmission of the
NDA for indiplon capsules. At the meeting the FDA requested that the resubmission include further analyses and
modifications of analyses previously submitted to address questions raised by the FDA in the initial review. This
reanalysis was completed. The FDA also requested, and we completed, a supplemental pharmacokinetic/food effect
profile of indiplon capsules including several meal types.

On June 12, 2007, we resubmitted our NDA for indiplon 5mg and 10mg capsules seeking clearance to market
indiplon capsules for the treatment of insomnia. The FDA accepted the NDA resubmission and established a
Prescription Drug User Fee Act (PDUFA) date of December 12, 2007. On December 12, 2007 we received an action

34

letter from the FDA stating the indiplon 5mg and 10mg capsules are approvable (2007 FDA Approvable Letter).
The 2007 FDA Approvable Letter acknowledged that the resubmitted NDA had addressed the issues raised in the
2006 FDA Approvable Letter, but set forth new requirements. The new requirements set forth in the 2007 FDA
Approvable Letter are the following: (i) an objective/subjective clinical trial in the elderly, (ii) a safety study
assessing the rates of adverse events occurring with indiplon when compared to a marketed product and (iii) a
preclinical study to evaluate indiplon administration during the third trimester of pregnancy.

On October 31, 2007, we entered into an exclusive license agreement with DSP, under which we licensed
rights to indiplon to DSP and agreed to collaborate with DSP on the development and commercialization of indiplon
in Japan. Pursuant to the license agreement, among other things, we received an up-front license fee of $20 million.
We are also eligible to receive additional milestone payments upon specified future events related to the
development and commercialization of indiplon in Japan. Should all milestones be achieved, we may be entitled
to payments totaling an additional $115 million. Additionally, we are entitled to royalties from DSP on future sales
of indiplon in Japan.

In July 2008 we held an end-of-review meeting with the FDA to discuss the 2007 FDA Approvable Letter. We
are currently awaiting the final minutes of this meeting. After receipt of the 2007 FDA Approvable Letter, we ceased
all indiplon clinical development activities in the United States as well as all pre-commercialization activities.

Restructuring programs and tender offer.

In July 2006 and August 2006, we announced a restructuring
program to prioritize research and development efforts and implement cost containment measures. As a result, we
terminated our entire sales force in July 2006 and reduced our research and development and general and
administrative staff in San Diego by approximately 100 employees in August 2006. In connection with this
restructuring, we recorded a one-time charge of approximately $9.5 million in 2006, of which $2.8 million was
included in research and development expense and $6.7 million was included in sales, general and administrative
expense. Restructuring charges are comprised of salary continuation, outplacement services, and other miscel-
laneous costs related to these reductions in force. Substantially all of these expenses were paid in cash during 2006.

In September 2006, we completed a tender offer to holders of outstanding options to purchase our common
stock under our 2003 Plan and certain prior option plans. The offer was open to eligible employees and active
consultants who held options with an exercise price of $20.00 or higher per share as of September 25, 2006. Certain
executives and members of the Board of Directors were not eligible to participate in the offer. Approximately
2.0 million options were exchanged or amended resulting in approximately 1.0 million new or amended option
grants and approximately 1.0 million cancelled option grants at completion of the offer. New or amended options
under the Offer vest annually over a period of three years and have a weighted average exercise price of $10.90.
Unamortized share based compensation expense, net of forfeiture rate, related to the offer totaled approximately
$8.7 million and is being amortized over 3 years commencing on the completion of the offer.

In December 2007, after receipt of the 2007 FDA Approvable Letter, we announced another restructuring
program to implement cost containment measures and to focus research and development efforts. As a result, we
reduced our research and development and general and administrative staff in San Diego by approximately
125 employees. In connection with this restructuring, we recorded a one-time charge of approximately $6.9 million
in the fourth quarter of 2007, of which $4.9 million was included in research and development expense and
$2.0 million was included in general and administrative expense. Restructuring charges are comprised of salary
continuation, outplacement services, and other miscellaneous costs related to these reductions in force. Substan-
tially all of these expenses were paid in cash during the first quarter of 2008.

During 2008, we incurred an additional one-time net charge of $2.1 million for severance related to certain
executives and other personnel departing the Company, primarily all of which was included in general and
administrative expense.

Liquidity and Capital Resources

At December 31, 2008, our cash, cash equivalents, and investments totaled $101.5 million compared with
$179.4 million at December 31, 2007. This decrease was primarily a result of our operating loss of $88.6 million for the
year ended December 31, 2008. At December 31, 2007, our cash, cash equivalents, and investments totaled

35

$179.4 million compared with $182.6 million at December 31, 2006. This $3.2 million decrease was primarily a result of
our operating loss of $207.3 million for the year ended December 31, 2007, which included $94.0 million of non-cash
expenditures related to the prepaid royalty impairment charge. The operating loss was offset by net cash received from
our sale-leaseback transaction of $61.0 million and upfront license fees received from DSP of $20.0 million.

Net cash used in operating activities during 2008 was $74.2 million compared to $59.3 million in 2007. This
increase was primarily due to severance payments of $7.4 million, and the timing of accounts payable and
reductions in accounts receivable. Net cash used in operating activities during 2007 was $59.3 million compared to
$99.3 million in 2006. This decrease was primarily due to up-front fees received from DSP of $20.0 million, and the
timing of accounts payable and reductions in accounts receivable.

Net cash provided by investing activities during 2008 was $44.4 million compared to $20.8 million in 2007 and
$120.3 million in 2006. These fluctuations resulted primarily from timing differences in investment purchases, sales
and maturities and the fluctuations in our portfolio mix between cash equivalents and short-term investment
holdings. We expect similar fluctuations to continue in future periods. Capital equipment purchases for 2008, 2007
and 2006 were $1.3 million, $0.6 million, and $3.1 million, respectively. Gross receipts from sales of equipment in
2008 totaled $0.6 million. Net capital equipment purchases for 2009 are expected to be $0.1 million.

Net cash used in financing activities during 2008 was $1.5 million compared to cash provided of $57.2 million
in 2007 and $10.1 million in 2006. During 2007, we closed the sale of our facility and associated real property for a
purchase price of $109.0 million and retired $47.7 million in mortgage debt related to the property. Other debt
repayments (primarily related to equipment loans) were $1.5 million, $4.5 million and $5.8 million in 2008, 2007
and 2006, respectively. We had no outstanding debt at December 31, 2008. Additionally, cash proceeds from the
issuance of common stock upon exercise of outstanding stock options and pursuant to our employee stock purchase
plan were $34,000, $0.6 million and $15.8 million in 2008, 2007 and 2006, respectively. The amount and frequency
of stock-related transactions are dependent upon the market performance of our common stock.

Auction Rate Securities. Our long-term investments at December 31, 2008 included (at par value)
$22.6 million of auction rate securities. With the liquidity issues experienced in global credit and capital markets,
these auction rate securities have experienced multiple failed auctions as the amount of securities submitted for sale
has exceeded the amount of purchase orders, and as a result, these affected securities are currently not liquid. All of our
auction rate securities are secured by student loans, which are backed by the full faith and credit of the federal
government (up to approximately 98% of the value of the student loan). Additionally, all of our auction rate securities
maintain the highest credit rating of AAA. All of these securities continue to pay interest according to their stated
terms (generally 120 basis points over the ninety-one day United States Treasury bill rate) with interest rates resetting
every 7 to 28 days. While it is not our intent to hold these securities until their stated ultimate maturity dates, these
investments are scheduled to ultimately mature between 2030 and 2047.

The valuation of our auction rate securities investment portfolio is subject to uncertainties that are difficult to
predict. The fair values of these securities were estimated utilizing a discounted cash flow analysis as of
December 31, 2008. The significant assumptions of this valuation model were discount margins ranging from
259 to 339 basis points which are based on industry recognized student loan sector indices, an additional liquidity
discount of 150 basis points and an estimated term to liquidity of 6 to 8 years. Other items this analysis considers are
the collateralization underlying the security investments, the creditworthiness of the counterparty, and the timing of
expected future cash flows. These securities were also compared, when possible, to other observable market data
with similar characteristics as the securities held by us. Although the auction rate security investments continue to
pay interest according to their stated terms, based on valuation models of the individual securities, we have
recognized in the consolidated statement of operations an unrealized loss of approximately $3.9 million in
investment income, net for auction rate securities that we have concluded that an other-than-temporary impairment
exists. The carrying value in long-term investments for these auction rate securities at December 31, 2008 was
$18.7 million.

During the fourth quarter of 2008, UBS AG (UBS) extended an offer of Auction Rate Securities Rights (ARS
Rights) to holders of illiquid auction rate securities that were maintained by UBS as of February 13, 2008. The ARS
Rights provide the holder with the ability to sell the auction rate securities, along with the ARS Rights, to UBS at the
par value of the auction rate securities, during an applicable exercise period. The ARS Rights grant UBS the sole

36

discretion and right to sell or otherwise dispose of auction rate securities at any time up until July 2, 2012, without
any prior notification of the holder, so long as the holder receives a payment of par upon any sale or disposition. The
ARS Rights are not transferable, not tradeable, and will not be quoted or listed on any securities exchange or any
other trading network. The offer period for the ARS Rights closed on November 14, 2008 and ARS Rights were
issued by UBS during the fourth quarter of 2008.

We have elected to participate in the ARS Rights program for all of our outstanding auction rate securities
maintained by UBS. We have $14.6 million (at par value) of ARS that are maintained by UBS. Under the terms of
the ARS Rights offer, our applicable exercise period begins on June 30, 2010 and ends July 2, 2012. Additionally,
we are eligible for a loan of up to 75% of the market value of the auction rate securities, should a loan be needed. It is
our intention to sell the auction rate securities and ARS Rights to UBS on June 30, 2010.

We elected to measure the ARS Rights under the fair value option of SFAS 159, “The Fair Value Option for
Financial Assets and Financial Liabilities — including an amendment of FASB Statement No. 115” (SFAS 159), to
mitigate volatility in reported earnings due to their linkage to the auction rate securities and recorded other income
of approximately $2.4 million, and a corresponding long term investment. Simultaneously, due to the ARS Rights
granted by UBS, we made a one-time election to transfer the related auction rate security holdings from available-
for-sale securities to trading securities. As a result of this transfer, we recognized an other-than-temporary loss of
approximately $2.6 million, and reversed the related temporary valuation allowance that was previously recorded in
other comprehensive loss. The recording of the ARS Rights and the recognition of the other-than-temporary
impairment loss resulted in a $0.2 million net impact to the consolidated statement of operations for the year ended
December 31, 2008. We anticipate that any future changes in the fair value of the ARS Rights will be offset by the
changes in the fair value of the related auction rate securities with no material net impact to the consolidated
statement of operations. The ARS Rights will continue to be measured at fair value under SFAS 159 until the earlier
of their maturity or exercise.

The two remaining auction rate securities continue to be treated as available-for-sale investments. These
auction rate securities have a par value of $8.0 million on which we have recognized a $1.3 million unrealized loss
for an other-than-temporary impairment in the consolidated statement of operations.

Changes to estimates and assumptions used in estimating the fair value of the auction rate securities and related
ARS Rights may provide materially different values. In addition, actual market exchanges, if any, may occur at
materially different amounts. For example, a reduction of the expected term to redemption assumption by 2 years
for the auction rate securities and related ARS Rights yielded a net increase in the valuation of these investments of
$0.3 million. Other factors that may impact the valuation of our auction rate securities and related ARS Rights
include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates
of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing
strength and quality of market credit and liquidity.

At present, in the event we need to access the funds that are in an illiquid state, we may not be able to do so
without the possible loss of principal, until a future auction for these investments is successful, another secondary
market evolves for these securities, until they are redeemed by the issuer or until they mature. If we are unable to sell
these securities in the market or they are not redeemed, we could be required to hold them to maturity. We do not
have a need to access these funds for operational purposes in 2009, nor the outstanding auction rate securities with
UBS prior to June 30, 2010, the beginning of the ARS Rights exercise period. We will continue to monitor and
evaluate these investments on an ongoing basis for impairment.

Shelf Registration Statement.

In November 2007, we filed a shelf registration statement with the Securities
and Exchange Commission, which was declared effective in December 2007. The shelf registration statement
allows us to issue shares of our common stock from time to time for an aggregate initial offering price of up to
$150 million. The specific terms of offerings, if any, under the shelf registration statement would be established at
the time of such offerings.

37

Factors That May Affect Future Financial Condition and Liquidity

We anticipate increases in expenditures as we continue to expand our research and development activities.
Because of our limited financial resources, our strategies to develop some of our programs include collaborative
agreements with major pharmaceutical companies and sales of our common stock in both public and private
offerings. Our collaborative agreements typically include a partial recovery of our research costs through license
fees, contract research funding and milestone revenues. Our collaborators are also financially and managerially
responsible for clinical development and commercialization. In these cases, the estimated completion date would
largely be under the control of the collaborator. We cannot forecast, with any degree of certainty, which other
proprietary products or indications, if any, will be subject to future collaborative arrangements, in whole or in part,
and how such arrangements would affect our capital requirements.

The following table summarizes our contractual obligations at December 31, 2008 and the effect such
obligations are expected to have on our liquidity and cash flows in future periods. Our license, research and clinical
development agreements are generally cancelable with written notice in 0-180 days. In addition to the minimum
payments due under our license and research agreements, we may be required to pay up to $22.3 million in
milestone payments, plus sales royalties, in the event that all scientific research under these agreements is
successful. Some of our clinical development agreements contain incentives for time-sensitive activities. Addi-
tionally, our facility lease agreement calls for us to maintain $50.0 million in cash and investments at all times, or
increase our security deposit by $5.0 million.

The funding necessary to execute our business strategies is subject to numerous uncertainties, which may
adversely affect our liquidity and capital resources. Completion of clinical trials may take several years or more, but
the length of time generally varies substantially according to the type, complexity, novelty and intended use of a
product candidate. It is also important to note that if a clinical candidate is identified, the further development of that
candidate can be halted or abandoned at any time due to a number of factors. These factors include, but are not
limited to, funding constraints, safety or a change in market demand.

An important element of our business strategy is to pursue the research and development of a diverse range of
product candidates for a variety of disease indications. We pursue this goal through proprietary research and
development as well as searching for new technologies for licensing opportunities. This allows us to diversify
against risks associated with our research and development spending. To the extent we are unable to maintain a
diverse and broad range of product candidates, our dependence on the success of one or a few product candidates
would increase.

The nature and efforts required to develop our product candidates into commercially viable products include
research to identify a clinical candidate, preclinical development, clinical testing, FDA approval and commer-
cialization. This process may cost in excess of $1 billion and can take in excess of 10 years to complete for each
product candidate.

We test our potential product candidates in numerous pre-clinical studies to identify disease indications for
which our product candidates may show efficacy. We may conduct multiple clinical trials to cover a variety of
indications for each product candidate. As we obtain results from trials, we may elect to discontinue clinical trials
for certain product candidates or for certain indications in order to focus our resources on more promising product

38

candidates or indications. The duration and the cost of clinical trials may vary significantly over the life of a project
as a result of differences arising during the clinical trial protocol, including, among others, the following:

(cid:129) we or the FDA or similar foreign regulatory authorities may suspend the trials;

(cid:129) we may discover that a product candidate may cause harmful side effects;

(cid:129) patient recruitment may be slower than expected; and

(cid:129) patients may drop out of the trials.

For each of our programs, we periodically assess the scientific progress and merits of the programs to
determine if continued research and development is economically viable. Certain of our programs have been
terminated due to the lack of scientific progress and lack of prospects for ultimate commercialization. Because of
the uncertainties associated with research and development of these programs, we may not be successful in
achieving commercialization. As such, the ultimate timeline and costs to commercialize a product cannot be
accurately estimated.

Our product candidates have not yet achieved FDA regulatory approval, which is required before we can
market them as therapeutic products in the United States. In order to proceed to subsequent clinical trial stages and
to ultimately achieve regulatory approval, the FDA must conclude that our clinical data establish safety and
efficacy. We must satisfy the requirements of similar regulatory authorities in foreign countries in order to market
products in those countries. The results from preclinical testing and early clinical trials may not be predictive of
results in later clinical trials. It is possible for a candidate to show promising results in clinical trials, but
subsequently fail to establish sufficient safety and efficacy data necessary to obtain regulatory approvals.

As a result of the uncertainties discussed above, among others, the duration and completion costs of our
research and development projects are difficult to estimate and are subject to considerable variation. Our inability to
complete our research and development projects in a timely manner or our failure to enter into collaborative
agreements, when appropriate, could significantly increase our capital requirements and could adversely impact our
liquidity. These uncertainties could force us to seek additional, external sources of financing from time to time in
order to continue with our business strategy. Our inability to raise additional capital, or to do so on terms reasonably
acceptable to us, would jeopardize the future success of our business.

We also may be required to make further substantial expenditures if unforeseen difficulties arise in other areas

of our business. In particular, our future capital requirements will depend on many factors, including:

(cid:129) continued scientific progress in our research and development programs;

(cid:129) the magnitude of our research and development programs;

(cid:129) progress with preclinical testing and clinical trials;

(cid:129) the time and costs involved in obtaining regulatory approvals;

(cid:129) the costs involved in filing and pursuing patent applications and enforcing patent claims;

(cid:129) competing technological and market developments;

(cid:129) the establishment of additional collaborations and strategic alliances;

(cid:129) the cost of manufacturing facilities and of commercialization activities and arrangements; and

(cid:129) the cost of product in-licensing and any possible acquisitions.

We believe that our existing capital resources, together with investment income and future payments due under
our strategic alliances, will be sufficient to satisfy our current and projected funding requirements for at least the
next 12 months. However, we cannot guarantee that our existing capital resources and anticipated revenues will be
sufficient to conduct and complete all of our research and development programs as planned.

We will require additional funding to continue our research and product development programs, to conduct
preclinical studies and clinical trials, for operating expenses, to pursue regulatory approvals for our product

39

candidates, for the costs involved in filing and prosecuting patent applications and enforcing or defending patent
claims, if any, for the cost of product in-licensing and for any possible acquisitions, and we may require additional
funding to establish manufacturing and marketing capabilities in the future. We may seek to access the public or
private equity markets whenever conditions are favorable. For example, we have an effective shelf registration
statement on file with the Securities and Exchange Commission which allows us to issue shares of our common
stock from time to time for an aggregate initial offering price up to $150 million. We may also seek additional
funding through strategic alliances and other financing mechanisms. We cannot assure you that adequate funding
will be available on terms acceptable to us, if at all. Any additional equity financings will be dilutive to our
stockholders and any additional debt may involve operating covenants that may restrict our business. If adequate
funds are not available through these means, we may be required to curtail significantly one or more of our research
or development programs or obtain funds through arrangements with collaborators or others. This may require us to
relinquish rights to certain of our technologies or product candidates. To the extent that we are unable to obtain
third-party funding for such expenses, we expect that increased expenses will result in increased losses from
operations. We cannot assure you that we will successfully develop our products under development or that our
products, if successfully developed, will generate revenues sufficient to enable us to earn a profit.

Interest Rate Risk

We are exposed to interest rate risk on our short-term investments. The primary objective of our investment
activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To
achieve this objective, we invest in highly liquid and high quality government and other debt securities. To minimize
our exposure due to adverse shifts in interest rates, we invest in short-term securities and ensure that the maximum
average maturity of our investments does not exceed 36 months. If a 10% change in interest rates were to have
occurred on December 31, 2008, this change would not have had a material effect on the fair value of our investment
portfolio as of that date. Due to the short holding period of our investments, we have concluded that we do not have a
material financial market risk exposure.

New Accounting Pronouncements

In December 2007, the FASB issued SFAS 141 (revised 2007), “Business Combinations” (SFAS 141(R)).
SFAS 141(R) establishes principles and requirements for how an acquirer recognizes and measures in its financial
statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the acquiree and
the goodwill acquired in connection with business combinations. SFAS 141(R) also establishes disclosure
requirements to enable the evaluation of the nature and financial effects of the business combination. SFAS 141(R)
is effective for fiscal years beginning on or after December 15, 2008. We do not expect the adoption of SFAS 141(R)
to have a material effect on our consolidated results of operations and financial condition.

In December 2007, the FASB issued SFAS 160, “Noncontrolling Interests in Consolidated Financial Statements —
an amendment of Accounting Research Bulletin No. 51” (SFAS 160). SFAS 160 establishes accounting and reporting
standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net
income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest, and the
valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS 160 also establishes
disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the
noncontrolling owners. SFAS 160 is effective for fiscal years beginning after December 15, 2008. We do not expect the
adoption of SFAS 160 to have a material effect on our consolidated results of operations and financial condition.

In March 2008, the FASB issued SFAS 161, “Disclosures about Derivative Instruments and Hedging
Activities, an amendment of FASB Statement No. 133” (SFAS 161). SFAS 161 applies to all derivative instruments
and related hedged items accounted for under SFAS 133, “Accounting for Derivative Instruments and Hedging
Activities” (SFAS 133). SFAS 161 requires entities to provide greater transparency about how and why an entity
uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS 133
and its related interpretations, and how derivative instruments and related hedged items affect an entity’s financial
position, results of operations and cash flows. SFAS 161 is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. We do not expect the adoption of SFAS 161 to have a
material effect on our consolidated results of operations and financial condition.

40

We also adopted the following accounting standards in 2008, none of which had a material effect on our

consolidated results of operations during such period or financial condition at the end of such period:

(cid:129) Emerging Issues Task Force EITF Issue 07-3, “Accounting for Non-Refundable Advance Payments for

Goods or Services to Be Used in Future Research and Development Activities”

(cid:129) SFAS 162, “The Hierarchy of Generally Accepted Accounting Principles”

We adopted SFAS 157, “Fair Value Measurements” (SFAS 157) and SFAS 157-3, “Determining the Value of a
Financial Asset When the Market for That Asset Is Not Active” (SFAS 157-3). SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about fair value measurements.
SFAS 157-3 expanded on the implementation guidance in SFAS 157 for estimating the present value of future
cash flows for some hard-to-value financial instruments such as auction rate securities. The adoption of SFAS 157
and SFAS 157-3 did not have a material impact on our consolidated results of operations and financial position.

We adopted SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities-Including an
amendment of FASB Statement No. 115.” SFAS 159 permits companies to choose to measure certain financial
assets and liabilities at fair value (the “fair value option”). If the fair value option is elected, any upfront costs and
fees related to the item must be recognized in earnings and cannot be deferred, e.g. debt issue costs. The fair value
election is irrevocable and may generally be made on an instrument-by-instrument basis, even if a company has
similar instruments that it elects not to fair value. At the adoption date, unrealized gains and losses on existing items
for which fair value has been elected are reported as a cumulative adjustment to beginning retained earnings. The
adoption of SFAS 159 did not have a material impact on our consolidated results of operations and financial position
as the fair value option was not elected for any of our financial assets or financial liabilities at the date of adoption.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
Neurocrine Biosciences, Inc.

We have audited the accompanying consolidated balance sheets of Neurocrine Biosciences, Inc. as of
December 31, 2008 and 2007, and the related consolidated statements of income, stockholders’ equity, and cash
flows for each of the three years in the period ended December 31, 2008. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Neurocrine Biosciences, Inc. at December 31, 2008 and 2007, and the
consolidated results of its operations and its consolidated cash flows for each of the three years in the period ended
December 31, 2008, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 1 to the consolidated financial statements, Neurocrine Biosciences, Inc. changed its
method of accounting and disclosures for fair value measurements and fair value reporting of financial assets and
liabilities in accordance with Statement of Financial Accounting Standards No. 157, Fair Value Measurements, and
Statement of Financial Accounting Standards No. 159, the Fair Value Option for Financial Assets and Financial
Liabilities — Including an amendment of FASB Statement No. 115.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Neurocrine Biosciences, Inc.’s internal control over financial reporting as of December 31, 2008,
based on the criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated February 2, 2009, expressed an unqualified
opinion thereon.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2008

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business Activities. Neurocrine Biosciences, Inc. (the Company or Neurocrine) incorporated in California
in 1992 and reincorporated in Delaware in 1996. The Company discovers, develops and intends to commercialize
drugs for the treatment of neurological and endocrine-related diseases and disorders. The Company’s product
candidates address some of the largest pharmaceutical markets in the world, including endometriosis, anxiety,
depression, pain, diabetes, irritable bowel syndrome, insomnia, and other neurological and endocrine related
diseases and disorders.

Subsidiaries of the Company include Neurocrine Continental, Inc. (formerly Neurocrine Commercial Oper-
ations, Inc.), a Delaware corporation and wholly owned subsidiary of the Company, and Neurocrine HQ Inc., a
Delaware corporation and wholly owned subsidiary of the Company, both of which are primarily inactive.

During 2008, the Company dissolved Science Park Center LLC and Neurocrine International LLC, which

previously were subsidiaries of the Company.

Principles of Consolidation. The consolidated financial statements include the accounts of Neurocrine as
well as its wholly owned subsidiaries. We do not have any significant interests in any variable interest entities. All
intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with accounting principles gen-
erally accepted in the United States requires management to make estimates and assumptions that affect the
amounts reported in the financial statements and the accompanying notes. Actual results could differ from those
estimates.

Reclassifications. Certain reclassifications have been made to previously reported amounts to conform to

current presentations.

Cash Equivalents. The Company considers all highly liquid investments with a maturity of three months or

less when purchased to be cash equivalents.

Short-Term Investments Available-for-Sale.

In accordance with Statement of Financial Accounting Stan-
dards (SFAS) No. 115, “Accounting for Certain Debt and Equity Securities,” (SFAS 115) short-term investments are
classified as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and
losses reported in other comprehensive loss. The amortized cost of debt securities in this category is adjusted for
amortization of premiums and accretion of discounts to maturity. Such amortization is included in investment
income. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-
sale securities are included in other income or expense. The cost of securities sold is based on the specific
identification method. Interest and dividends on securities classified as available-for-sale are included in investment
income.

Concentration of Credit Risk. Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash, cash equivalents and short-term investments. The Company has established
guidelines to limit its exposure to credit expense by placing investments with high credit quality financial
institutions, diversifying its investment portfolio and placing investments with maturities that maintain safety
and liquidity.

Collaboration Agreements. During the years ended December 31, 2008, 2007 and 2006, collaborative

research and development agreements accounted for substantially all of the Company’s revenue.

Property and Equipment. Property and equipment are stated at cost and depreciated over the estimated
useful lives of the assets using the straight-line method. Building costs were depreciated over an average estimated
useful life of 25 years and equipment is over three to seven years. Leasehold improvements are depreciated over the
shorter of their estimated useful lives or the remaining lease term.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Industry Segment and Geographic Information. The Company operates in a single industry segment — the
discovery and development of therapeutics for the treatment of neurological and endocrine related diseases and
disorders. The Company had limited foreign based operations for the years ended December 31, 2008, 2007 and
2006.

Other Non-Current Assets. Other non-current assets include $3.1 million and $4.7 million, respectively, of
mutual fund investments related to the Company’s nonqualified deferred compensation plan for certain employees
as of December 31, 2008 and 2007, respectively. Net unrealized losses related to these mutual funds were
approximately $1.6 million and $0.2 million as of December 31, 2008 and December 31, 2007, respectively. All of
the assets held in the Company’s nonqualified deferred compensation plan are recorded at fair value in accordance
with SFAS 115 with fair value disclosures presented in accordance with SFAS No. 157, “Fair Value Measurements,”
(SFAS 157) (as described in Note 4). The values are categorized as Level 1 assets as they have been obtained from
quoted prices in active markets for identical assets. Additionally, the Company has recorded a corresponding
liability for the deferred compensation plan in other liabilities.

The participants in the deferred compensation plan may select from a variety of deemed investment options
and have the ability to make changes in such deemed investments on a daily basis, subject to Plan limitations. A
participant may elect to receive all or a portion of his or her deferred compensation on a fixed payment date of his or
her choosing and may delay that fixed date, subject to plan limitations. The Board of Directors may, at its sole
discretion, suspend or terminate the plan.

Impairment of Long-Lived Assets.

In accordance with SFAS No. 144, “Accounting for the Impairment or
Disposal of Long-Lived Assets,” (SFAS 144) if indicators of impairment exist, the Company assesses the
recoverability of the affected long-lived assets by determining whether the carrying value of such assets can be
recovered through undiscounted future operating cash flows. If the carrying amount is not recoverable, the
Company measures the amount of any impairment by comparing the carrying value of the asset to the present value
of the expected future cash flows associated with the use of the asset.

The Company carried as a long-lived asset on its balance sheet a prepaid royalty arising from its acquisition in
February 2004 of Wyeth’s financial interest in the Company’s drug candidate, indiplon, for $95.0 million,
consisting of $50.0 million in cash and $45.0 million in the Company’s common stock. During the fourth quarter
of 2007, the Company received a second “approvable” letter from the United States Food and Drug Administration.
This second letter requested additional preclinical and clinical trials, which raised a significant amount of
uncertainty regarding future clinical development of indiplon. Based on this significant uncertainty, the Company
determined that the prepaid royalty was impaired, and a non-cash charge of $94.0 million related to this impairment
was required under SFAS 144 to write the value down to zero.

Fair Value of Financial Instruments. Financial instruments, including cash and cash equivalents, accounts
receivable, accounts payable, and accrued liabilities, are carried at cost, which management believes approximates
fair value because of the short-term maturity of these instruments.

Revenue Recognition. Revenues under collaborative research agreements are recognized as research costs
and are incurred over the period specified in the related agreement or as the services are performed. These
agreements are on a best-efforts basis and do not require scientific achievement as a performance obligation and
provide for payment to be made when costs are incurred or the services are performed. All fees received from the
Company’s collaborative partners are nonrefundable. Upfront, nonrefundable payments for license fees and
advance payments for sponsored research revenues received in excess of amounts earned are classified as deferred
revenue and recognized as income over the contract or development period. Estimating the duration of the
development period includes continual assessment of development stages and regulatory requirements. Milestone
payments are recognized as revenue upon achievement of pre-defined scientific events, which requires substantive
effort, and for which achievement of the milestone was not readily assured at the inception of the agreement.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

License fees are received in exchange for a grant to use the Company’s proprietary technologies on an as-is basis for
the term of the collaborative agreement. Milestones are received for specific scientific achievements determined at the
beginning of the collaboration. These achievements are substantive and are based on the success of scientific efforts.

Comprehensive Income/Loss. Comprehensive income/loss is calculated in accordance with SFAS No. 130,
“Comprehensive Income”, (SFAS 130). SFAS 130 requires the disclosure of all components of comprehensive
income/loss, including net income and changes in equity during a period from transactions and other events and
circumstances generated from non-owner sources. The Company’s other comprehensive income/loss consisted of
unrealized gains and losses on investments and is reported in the statements of stockholders’ equity.

Research and Development Expenses. Research and development (R&D) expenses include related salaries,
contractor fees, clinical trial costs, facilities costs, administrative expenses and allocations of corporate costs. All
such costs are charged to R&D expense as incurred. These expenses result from the Company’s independent R&D
efforts as well as efforts associated with collaborations and in-licensing arrangements. In addition, the Company
funds R&D at other companies and research institutions under agreements, which are generally cancelable. The
Company reviews and accrues clinical trial expenses based on work performed, which relies on estimates of total
costs incurred based on patient enrollment, completion of patient studies and other events. The Company follows
this method since reasonably dependable estimates of the costs applicable to various stages of a research agreement
or clinical trial can be made. Accrued clinical costs are subject to revisions as trials progress to completion.
Revisions are charged to expense in the period in which the facts that give rise to the revision become known.

Restructuring. During 2008, the Company incurred a net charge of $2.1 million, primarily included in
general and administrative expense, for severance related to certain executives and other personnel departing the
Company.

During the fourth quarter of 2007, the Company announced staff reductions of approximately 125 employees
at its San Diego campus, as part of its restructuring program to prioritize its research and development programs. As
a result, the Company communicated to affected employees a plan of organizational restructuring through
involuntary terminations. Pursuant to SFAS No. 112, “Employers’ Accounting for Postemployment Benefits”
and SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” (SFAS 146) the Company
recorded a charge of approximately $6.9 million in 2007, of which $4.9 million was included in research and
development and $2.0 million was included in sales, general and administrative expense. The majority of this
amount was paid out in the first quarter of 2008.

During 2006, the Company eliminated its entire sales force and also reduced its research and development and
general and administrative staff in San Diego by approximately 100 employees. Pursuant to SFAS 146, the
Company recorded a charge of approximately $9.5 million in 2006 related to this reduction in workforce, of which
$2.8 million was included in research and development expense and $6.7 million was included in sales, general and
administrative expense. Substantially all costs were paid out in cash during 2006.

As of December 31, 2008, the Company had a remaining balance of approximately $1.6 million of accrued
restructuring expenses included in the consolidated balance sheet. The liability will be paid over the remaining
contractual period of certain severance agreements. The changes to the accrued liability during 2008 are as follows
(in thousands):

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Retention Program. On February 27, 2008, the Board of Directors of the Company approved an employee
retention program (Retention Program) to provide the Company with a mechanism to retain its non-officer and
executive officer employees who were not subject to the Company’s restructuring programs. As part of the
Retention Program, the Board approved a one-time cash retention payment totaling $3.2 million, 60% of which was
paid in the first quarter of 2008 and the remaining 40% of which was paid in the fourth quarter of 2008. In addition,
the Board approved the issuance of restricted stock units (RSUs) covering an aggregate of 1.2 million shares and
stock options covering an aggregate of 501,000 shares to its executive officers and certain employees, all of which
were issued in the first quarter of 2008.

Share-Based Compensation. Prior to January 1, 2006, the Company accounted for share-based compen-
sation under the recognition and measurement principles of Accounting Principles Board Opinion No. 25,
“Accounting for Stock Issued to Employees,” (APB 25). Under APB 25, the Company measured compensation
expense for its share-based compensation using the intrinsic value method, that is, as the excess, if any, of the fair
market value of the Company’s stock at the grant date over the amount required to be paid to acquire the stock, and
provided the disclosures required by SFAS 123, “Accounting for Stock-Based Compensation,” (SFAS 123) and
SFAS 148, “Accounting for Stock-Based Compensation-Transition and Disclosure,” (SFAS 148).

Effective January 1, 2006, the Company began recording compensation expense associated with stock options
and other equity-based compensation in accordance with SFAS No. 123 (revised 2004), “Share-Based Payment,”
(SFAS 123R) using the modified prospective transition method and therefore has not restated results for prior
periods. Under the modified prospective transition method, share-based compensation expense for 2006 includes:
1) compensation expense for all share-based awards granted on or after January 1, 2006 as determined based on the
grant-date fair value estimated in accordance with the provisions of SFAS 123R; and 2) compensation expense for
share-based compensation awards granted prior to, but not yet vested as of January 1, 2006, based on the grant date
fair value estimated in accordance with the original provisions of SFAS 123. The Company recognizes compen-
sation expense on a straight-line basis over the requisite service period of the award, which is generally four years;
however, certain provisions in the Company’s equity compensation plans provide for shorter vesting periods under
certain circumstances.

On August 1, 2007, the Company amended and restated the Neurocrine Biosciences, Inc. Nonqualified
Deferred Compensation Plan (the Plan). Under the terms of the amended and restated Plan, the Company is now
required to distribute shares in order to settle any share-based compensation deferred into the Plan by participants.
Additionally, participants can no longer diversify share-based awards that are placed into the Plan. In accordance
with SFAS 123R and Emerging Issues Task Force 97-14, “Accounting for Deferred Compensation Arrangements
Where Amounts Earned Are Held in a Rabbi Trust and Invested”, the Company has reclassified the portion of the
liability representing our obligation related to share-based compensation that had vested as of the date of the Plan
modification to additional paid-in-capital. There was no effect on our previously reported net income or accu-
mulated deficit.

Investment Income.

Investment income is comprised of interest and dividends earned on cash, cash
equivalents and investments as well as gains and losses realized from activity in the Company’s investment
portfolio. The following table presents certain information related to the components of investment income (in

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Net Loss Per Share. The Company computes net loss per share in accordance with SFAS No. 128, “Earnings
Per Share” (SFAS 128). Under the provisions of SFAS 128, basic net income (loss) per share is computed by
dividing the net income (loss) for the period by the weighted average number of common shares outstanding during
the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the
weighted average number of common and common equivalent shares outstanding during the period. Potentially
dilutive securities comprised of incremental common shares issuable upon the exercise of stock options and
warrants, were excluded from historical diluted loss per share because of their anti-dilutive effect. Dilutive common
stock equivalents would include the dilutive effects of common stock options and warrants for common stock.
Potentially dilutive securities totaled 39,000, 1.2 million and 1.0 million for the years ended December 31, 2008,
2007 and 2006, respectively, and were excluded from the diluted earnings per share because of their anti-dilutive
effect.

Impact of Recently Issued Accounting Standards.

In December 2007, the FASB issued SFAS No. 141
(revised 2007), “Business Combinations” (SFAS 141(R)). SFAS 141(R) establishes principles and requirements for
how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities
assumed, any noncontrolling interest in the acquiree and the goodwill acquired in connection with business
combinations. SFAS 141(R) also establishes disclosure requirements to enable the evaluation of the nature and
financial effects of the business combination. SFAS 141(R) is effective for fiscal years beginning on or after
December 15, 2008. The Company does not expect the adoption of SFAS 141(R) to have a material effect on its
consolidated results of operations and financial condition.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial
Statements — an amendment of Accounting Research Bulletin No. 51” (SFAS 160). SFAS 160 establishes
accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent,
the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a
parent’s ownership interest, and the valuation of retained noncontrolling equity investments when a subsidiary is
deconsolidated. SFAS 160 also establishes disclosure requirements that clearly identify and distinguish between the
interests of the parent and the interests of the noncontrolling owners. SFAS 160 is effective for fiscal years
beginning after December 15, 2008. The Company does not expect the adoption of SFAS 160 to have a material
effect on its consolidated results of operations and financial condition.

In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging
Activities, an amendment of FASB Statement No. 133” (SFAS 161). SFAS 161 applies to all derivative instruments
and related hedged items accounted for under SFAS 133, “Accounting for Derivative Instruments and Hedging
Activities” (SFAS 133). SFAS 161 requires entities to provide greater transparency about how and why an entity
uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS 133
and its related interpretations, and how derivative instruments and related hedged items affect an entity’s financial
position, results of operations and cash flows. SFAS 161 is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. The Company does not expect the adoption of SFAS 161 to
have a material effect on its consolidated results of operations and financial condition.

The Company also adopted the following accounting standards in 2008, none of which had a material effect on

its consolidated results of operations during such period or financial condition at the end of such period:

(cid:129) Emerging Issues Task Force EITF Issue 07-3, “Accounting for Non-Refundable Advance Payments for

Goods or Services to Be Used in Future Research and Development Activities”

(cid:129) SFAS No. 162, “The Hierarchy of Generally Accepted Accounting Principles”

The Company adopted SFAS 157, “Fair Value Measurements” (SFAS 157) and SFAS No. 157-3, “Deter-
mining the Value of a Financial Asset When the Market for That Asset Is Not Active” (SFAS 157-3). SFAS 157
defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value
measurements. SFAS 157-3 expanded on the implementation guidance in SFAS 157 for estimating the present value

of future cash flows for some hard-to-value financial instruments such as auction rate securities. The adoption of
SFAS 157 and SFAS 157-3 did not have a material impact on the Company’s consolidated results of operations and
financial position; however additional disclosure has been added to the financial statements in Note 4.

The Company adopted SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities-
Including an amendment of FASB Statement No. 115” (SFAS159). SFAS 159 permits companies to choose to
measure certain financial assets and liabilities at fair value (the “fair value option”). If the fair value option is
elected, any upfront costs and fees related to the item must be recognized in earnings and cannot be deferred, e.g.
debt issue costs. The fair value election is irrevocable and may generally be made on an instrument-by-instrument
basis, even if a company has similar instruments that it elects not to measure at fair value. At the adoption date,
unrealized gains and losses on existing items for which the fair value option has been elected are reported as a
cumulative adjustment to beginning retained earnings. The adoption of SFAS 159 did not have a material impact on
the Company’s consolidated results of operations and financial position as the fair value option was not elected for
any of the Company’s financial assets or financial liabilities at the date of adoption.

NOTE 3. LONG-TERM INVESTMENTS

The Company’s long-term investments at December 31, 2008 included (at par value) $22.6 million of auction
rate securities. With the liquidity issues experienced in global credit and capital markets, these auction rate
securities have experienced multiple failed auctions as the amount of securities submitted for sale has exceeded the
amount of purchase orders, and as a result, these affected securities are currently not liquid. All of the Company’s

53

NEUROCRINE BIOSCIENCES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

auction rate securities are secured by student loans, which are backed by the full faith and credit of the federal
government (up to approximately 98% of the value of the student loan). Additionally, all of the Company’s auction
rate securities maintain the highest credit rating of AAA. All of these securities continue to pay interest according to
their stated terms (generally 120 basis points over the ninety-one day United States Treasury bill rate) with interest
rates resetting every 7 to 28 days. While it is not the Company’s intent to hold these securities until their stated
ultimate maturity dates, these investments are scheduled to ultimately mature between 2030 and 2047.

The valuation of the Company’s auction rate securities investment portfolio is subject to uncertainties that are
difficult to predict. The fair values of these securities are estimated utilizing a discounted cash flow analysis as of
December 31, 2008. The significant assumptions of this valuation model were discount margins ranging from
259 to 339 basis points which are based on industry recognized student loan sector indices, required rate of return of
150 basis points and an estimated term to liquidity of 6 to 8 years. Other items this analysis considers are the
collateralization underlying the security investments, the creditworthiness of the counterparty, and the timing of
expected future cash flows. These securities were also compared, when possible, to other observable market data
with similar characteristics as the securities held by the Company. Although the auction rate security investments
continue to pay interest according to their stated terms, based on valuation models of the individual securities, the
Company has recognized in the consolidated statement of operations a loss of approximately $3.9 million on
auction rate securities in other income and expense for which for the Company has concluded that an other-than-
temporary impairment exists. The carrying value in long-term investments for these auction rate securities at
December 31, 2008 is $18.7 million.

During the fourth quarter of 2008, UBS AG (UBS) extended an offer of Auction Rate Securities Rights (ARS
Rights) to holders of illiquid auction rate securities that were maintained by UBS as of February 13, 2008. The ARS
Rights provide the holder with the ability to sell the auction rate securities, along with the ARS Rights, to UBS at the
par value of the auction rate securities, during an applicable exercise period. The ARS Rights grant UBS the sole
discretion and right to sell or otherwise dispose of auction rate securities at any time up until July 2, 2012, without
any prior notification of the holder, so long as the holder receives a payment of par upon any sale or disposition. The
ARS Rights are not transferable, not tradeable, and will not be quoted or listed on any securities exchange or any
other trading network. The offer period for the ARS Rights closed on November 14, 2008 and ARS Rights were
issued by UBS during the fourth quarter of 2008.

The Company has elected to participate in the ARS Rights program for all of its outstanding auction rate
securities maintained by UBS. The Company has $14.6 million (par value) of ARS that are maintained by UBS.
Under the terms of the ARS Rights offer, the applicable exercise period begins on June 30, 2010 and ends July 2,
2012. Additionally, the Company is eligible for a loan of up to 75% of the market value of the auction rate securities,
should a loan be needed. It is the Company’s intention to sell the auction rate securities and ARS Rights to UBS on
June 30, 2010.

The Company elected to measure the ARS Rights under the fair value option of SFAS 159 to mitigate volatility
in reported earnings due to their linkage to the auction rate securitites, and recorded income of approximately
$2.4 million, and a corresponding long term investment. The ARS Rights were valued in a similar fashion to the
auction rate securities as described above. Simultaneously, due to the ARS Rights granted by UBS, the Company
made a one-time election to transfer the related auction rate security holdings from available-for-sale securities to
trading securities. As a result of this transfer, the Company recognized an other-than-temporary loss of approx-
imately $2.6 million, and reversed the related temporary valuation allowance that was previously recorded in other
comprehensive loss. The recording of the ARS Rights and the recognition of the other-than-temporary impairment
loss resulted in a $0.2 million net impact to the consolidated statement of operations for the year ended
December 31, 2008. The Company anticipates that any future changes in the fair value of the ARS Rights will
be offset by the changes in the fair value of the related auction rate securities with no material net impact to the
consolidated statement of operations. The ARS Rights will continue to be measured at fair value under SFAS 159
until the earlier of their maturity or exercise.

54

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The two remaining auction rate securities continue to be treated as available-for-sale investments. These
auction rate securities have a par value of $8.0 million on which the Company has recognized a $1.3 million
unrealized loss for an other-than-temporary impairment in the consolidated statement of operations.

At present, in the event the Company needs to access the funds that are in an illiquid state, the Company may
not be able to do so without the possible loss of principal, until a future auction for these investments is successful,
another secondary market evolves for these securities, until they are redeemed by the issuer or they mature. If the
Company is unable to sell these securities in the market or they are not redeemed, the Company could be required to
hold them to maturity.

Changes to estimates and assumptions used in estimating the fair value of the auction rate securities and related
ARS Rights may provide materially different values. In addition, actual market exchanges, if any, may occur at
materially different amounts. For example, a reduction of the expected term to redemption assumption by 2 years
for the auction rate securities and related ARS Rights yielded a net increase in on the valuation of these investments
of $0.3 million. Other factors that may impact the valuation of our auction rate securities and related ARS Rights
include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates
of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing
strength and quality of market credit and liquidity.

NOTE 4. FAIR VALUE MEASUREMENTS

As described in Note 1, the Company adopted SFAS 157 on January 1, 2008. SFAS 157, which among other
things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for
each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. SFAS 157
clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to
transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based
measurement that should be determined based on assumptions that market participants would use in pricing an asset
or liability. As a basis for considering such assumptions, SFAS 157 establishes a three-tier fair value hierarchy,
which prioritizes the inputs used in measuring fair value as follows:

Level 1: Observable inputs such as quoted prices in active markets;
Level 2:

Inputs, other than the quoted prices in active markets, that are observable either directly or
indirectly; and

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to

develop its own assumptions.

Cash, cash equivalents, and investments measured at fair value as of December 31, 2008 are classified below

based on the three fair value hierarchy tiers described above (in millions):

(1) Securities are classified as available-for-sale.

(2) The Company transferred a portion of its auction rate securities from available-for-sale to trading in the fourth
quarter of 2008. The fair value of these auction rate securities was estimated based on the following: (i) the
underlying structure of each security; (ii) the present value of future principal and interest payments discounted
at rates considered to reflect current market conditions; (iii) consideration of the probabilities of default,
auction failure, or repurchase at par for each period; (iv) the expected term to liquidity; and (v) its market

NOTE 7. COMMITMENTS AND CONTINGENCIES

Real Estate.

In December 2007, the Company closed the sale of its facility and associated real property for a
purchase price of $109.0 million. As part of the sale the Company retired the entire $47.7 million in mortgage debt
previously outstanding with respect to the facility and associated real property, and received cash of $61.0 million
net of transaction costs and debt retirement. Upon the closing of the sale of the facility and associated real property,
the Company entered into a lease agreement whereby it leased back the facility for an initial term of 12 years. This
lease has been characterized as an operating lease for financial reporting purposes.

Under the terms of the lease, the Company pays a basic annual rent of $7.6 million (subject to an annual fixed
percentage increase, as set forth in the agreement), plus a 3.5% annual management fee, property taxes and other
normal and necessary expenses associated with the lease such as utilities, repairs and maintenance, etc. In lieu of a
cash security deposit under the lease agreement, Wells Fargo Bank, N.A. issued on the Company’s behalf a letter of
credit in the amount of $5.7 million. The letter of credit is secured by a deposit of $6.4 million carried as restricted
cash on the balance sheet. The Company has the right to extend the lease for two consecutive ten-year terms and will
have the first right of refusal to lease, at market rates, any facilities built on the sold vacant lot. Additionally, the
Company had a repurchase right to all of the properties which could have been exercised during the fourth year of
the lease.

In accordance with SFAS No. 98, “Accounting for Leases: Sale-Leaseback Transactions Involving Real Estate,
Sales-Type Leases of Real Estate, Definition of the Lease Term, and Initial Direct Costs of Direct Financing
Leases” (SFAS 98) and SFAS No. 66, “Accounting for Sales of Real Estate” (SFAS 66) the Company initially
deferred the gain on the sale of the building and related vacant parcel due to the repurchase right. The Company
established a long-term liability of $108.7 million upon the close of the transaction, essentially the gross proceeds
from the real estate sale, and the conveyed real estate assets remained on the Company’s balance sheet as of
December 31, 2007.

Effective December 10, 2008, the Company entered into a first amendment to the lease. The lease amendment
provides for the renovation of the front building in a manner that facilitates multiple tenant usage and also
establishes a mechanism for the Company to terminate its use of the front building. The Company continues to
occupy the rear building.

Pursuant to the terms of the lease amendment, the Company is obligated to reimburse the landlord for the total
cost of renovating a portion of the front building such that the front building becomes suitable for multiple tenant
usage. The Company and the landlord will work in good faith to use commercially reasonable efforts to keep the
total cost of the renovation from exceeding $5.5 million. The Company made a one-time payment of $1.0 million
toward renovation costs in January 2009 and will reimburse the landlord for the balance of the renovation costs over
a four year period through an increase in monthly rental payments (currently estimated at $108,000 per month)
beginning in October 2008. Furthermore, the lease amendment provides that the landlord shall seek to enter into
leases with replacement tenants for portions of the front building. In connection with each replacement lease, the

57

NEUROCRINE BIOSCIENCES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Company shall be granted a pro rata reduction in rent under the lease. The Company is required to pay all tenant
improvement costs, lease termination costs and leasing commissions in connection with each replacement lease.

The lease amendment also terminated the Company’s right to repurchase any portion of the facility or real
property. As a result of the termination of the repurchase right, during the fourth quarter of 2008, the Company
removed from its balance sheet the long-term liability of $108.7 million and the related previously conveyed real
estate related assets of $69.6 million. Additionally, the Company began to recognize the deferred gain of
$39.1 million on the sale of the real estate in accordance with SFAS 66 and SFAS 98. During 2008, the Company
recognized $3.5 million of the deferred gain and will recognize the balance of the deferred gain over the remaining
lease term.

As a result of signing the lease amendment and physically vacating the front building, the Company triggered a
cease-use date for the front building and has estimated lease termination costs in accordance with SFAS 146.
Estimated lease termination costs for the front building include the net present value of future minimum lease
payments, taxes, insurance, construction, and maintenance costs from the cease-use date to the end of the remaining
lease term net of estimated sublease rental income. During the fourth quarter of 2008, the Company recorded an
expense of $15.7 million for the net present value of these estimated lease termination costs, of which $0.3 million
was paid in 2008. Additionally, certain other costs such as leasing commissions and legal fees will be expensed by
the Company as incurred in conjunction with the sublease of the vacated office space.

Rent Expense. Rent expense was $1.1 million, $0.3 million and $1.2 million for the years ended
December 31, 2008, 2007 and 2006, respectively. Rent paid under the leaseback for the facility was treated as
interest expense in accordance with SFAS 98 for the period where the repurchase right existed. This charge totaled
$7.0 million and $0.6 million in 2008 and 2007, respectively. The Company recognizes rent expense on a straight-
line basis.

Equipment Loans. The Company had entered into equipment financing arrangements with lenders to
finance equipment purchases, which expired on various dates through the year 2008 and bore interest at rates
between 6.3% and 7.3%. The debt obligations were repayable in monthly installments and were secured by the
financed equipment. Amounts outstanding under these loans at December 31, 2007 totaled $1.5 million. These
equipment loans were fully repaid during 2008.

Product Liability. The Company’s business exposes it to liability risks from its potential drug products. A
successful product liability claim or series of claims brought against the Company could result in payment of
significant amounts of money and divert management’s attention from running the business. The Company may not
be able to maintain insurance on acceptable terms, or the insurance may not provide adequate protection in the case
of a product liability claim. To the extent that product liability insurance, if available, does not cover potential
claims, the Company would be required to self-insure the risks associated with such claims. The Company believes
that it carries reasonably adequate insurance for product liability claims.

Licensing and Research Agreements. The Company has entered into licensing agreements with various
universities and research organizations, which are generally cancelable at the option of the Company with terms
ranging from 0-180 days written notice. Under the terms of these agreements, the Company has received licenses to
research tools, know-how and technology claimed, in certain patents or patent applications. The Company is
required to pay fees, milestones and/or royalties on future sales of products employing the technology or falling
under claims of a patent, and some of the agreements require minimum royalty payments. Some of the agreements
also require the Company to pay expenses arising from the prosecution and maintenance of the patents covering the
licensed technology. The Company continually reassesses the value of the license agreements and cancels them
when research efforts are discontinued on these programs. If all licensed and research candidates are successfully
developed, the Company may be required to pay milestone payments of approximately $22.3 million over the lives
of these agreements, in addition to royalties on sales of the affected products at rates ranging up to 6%. Due to the

58

NEUROCRINE BIOSCIENCES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

uncertainties of the development process, the timing and probability of the milestone and royalty payments cannot
be accurately estimated.

Related Party Transactions. The Company has entered into agreements with a research facility for
technology. A director of the Company is an employee of this research facility. During the years ended Decem-
ber 31, 2008, 2007 and 2006, the Company paid approximately $425,000, $80,000 and $375,000, respectively, to
the research facility for this technology.

Clinical Development Agreements. The Company has entered into agreements with various vendors for the
pre-clinical and clinical development of its product candidates, which are generally cancelable at the option of the
Company for convenience or performance, with terms ranging from 0-180 days written notice. Under the terms of
these agreements, the vendors provide a variety of services including conducting pre-clinical development research,
manufacturing clinical compounds, enrolling patients, recruiting patients, monitoring studies, data analysis and
regulatory filing assistance. Payments under these agreements typically include fees for services and reimburse-
ment of expenses. Some agreements also may include incentive bonuses for time-sensitive activities. The timing of
payments due under these agreements was estimated based on current schedules of clinical studies in progress.

NOTE 8. SHARE-BASED COMPENSATION

Share-Based Compensation Plans. The Company grants stock options, restricted stock units and stock
bonuses (collectively, share-based compensation) to its employees and directors under the 2003 Incentive Stock
Plan, as amended (the 2003 Plan) and grants stock options to certain employees pursuant to Employment
Commencement Nonstatutory Stock Options. Until June 30, 2006, eligible employees could also purchase shares
of the Company’s common stock at 85% of the fair market value on the last day of each six-month offering period
under the Company’s Amended and Restated Employee Stock Purchase Plan. The benefits provided under these
plans are share-based compensation subject to the provisions of SFAS 123R.

Since 1992, the Company has authorized a total of 14.7 million shares of common stock for issuance pursuant
to its 1992 Plan, 1996 Director Option Plan, 1997 Northwest Neurologic, Inc. Restated Incentive Stock Plan, 2001
Plan, several Employment Commencement Nonstatutory Stock Option Agreements and the 2003 Plan (collectively,
the Option Plans). The Option Plans provide for the grant of stock options, restricted stock, restricted stock units,
and stock bonuses to officers, directors, employees, and consultants of the Company. Currently, all new grants of
stock options are made from the 2003 Plan or through Employment Commencement Nonstatutory Stock Option
Agreements. As of December 31, 2008, of the 14.7 million shares reserved for issuance under the Option Plans,

59

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

2.1 million of these shares were originally reserved for issuance pursuant to the terms of the Company’s 1992 Plan,
1996 Director Stock Option Plan and 2001 Plan and would currently be available for issuance but for the Company’s
determination in 2003 not to make further grants under these plans; 6.4 million were issued upon exercise of stock
options previously granted or pursuant to restricted stock or stock bonus awards; 5.1 million were subject to
outstanding options and restricted stock units; and 1.0 million remained available for future grant under the 2003
Plan. Share awards made under the 2003 Plan that are later cancelled due to forfeiture or expiration return to the
pool available for future grants.

The Company issues new shares upon the exercise of stock options, the issuance of stock bonus awards and

vesting of restricted stock units.

The Company’s net loss for the years ended December 31, 2008, 2007 and 2006 includes $8.0 million
$10.0 million and $14.4 million of compensation expense respectively, related to the Company’s share-based
compensation awards. The compensation expense related to the Company’s share-based compensation arrange-
ments is recorded as components of sales, general and administrative expense and research and development
expense ($4.1 million and $3.9 million, respectively, for the year ended December 31, 2008). SFAS 123R requires
that cash flows resulting from tax deductions in excess of the cumulative compensation cost recognized for options
exercised (excess tax benefits) be classified as cash inflows provided by financing activities and cash outflows used
in operating activities. Due to the Company’s net loss position, no tax benefits have been recognized in the
consolidated statements of cash flows.

In November 2005, the FASB issued Staff Position (FSP) No. FAS 123(R)-3, “Transition Election Related to
Accounting for Tax Effects of Share-Based Payment Awards” (FSP 123R-3). Neurocrine has elected to adopt the
alternative transition method provided in the FSP 123R-3 for calculating the tax effects of stock-based compen-
sation pursuant to SFAS 123R. The alternative transition method includes simplified methods to establish the
beginning balance of the APIC pool related to the tax effects of employee stock-based compensation, and to
determine the subsequent impact on the APIC pool and consolidated statements of cash flows of the tax effects of
employee stock-based compensation awards that are outstanding upon adoption of SFAS 123R.

Vesting Provisions of Share-Based Compensation. Stock options granted under the Option Plans primarily
have terms of up to ten years from the date of grant, and generally vest over a three to four-year period. Stock
bonuses granted under the Option Plans generally have vesting periods ranging from two to four years. Restricted
stock units granted under the Option Plans generally have vesting periods of three years. The expense recognized
under SFAS 123R is generally recognized ratably over the vesting period. However, certain retirement provisions in
the Option Plans provide that employees who are age 55 or older, and have five or more years of service with the
Company will be entitled to accelerated vesting of all of the unvested stock option awards upon retirement from the
Company. In these cases, share-based compensation expense may be recognized over a shorter period of time, and
in some cases the entire share-based compensation expense may be recognized upon grant of the share-based
compensation award. Effective January 1, 2006, the maximum contractual term for all options granted from the
2003 Plan was reduced to seven years.

Stock Options. The exercise price of all options granted during the years ended December 31, 2008, 2007
and 2006 was equal to the market value on the date of grant. The estimated fair value of each option award granted
was determined on the date of grant using the Black-Scholes option valuation model with the following weighted-
average assumptions for option grants during the years ended December 31, 2008, 2007 and 2006:

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected term of
the Company’s employee stock options. The expected volatility is based on the historical volatility of the
Company’s stock. The Company has not paid any dividends on common stock since its inception and does not
anticipate paying dividends on its common stock in the foreseeable future. Per Staff Accounting Bulletin 107, the
Company used the simplified method to compute the expected option term for all options granted. The simplified
method was used because the contractual life of the amended or exchanged options varied from approximately three
to seven years. The simplified method was used for all subsequent grants because the decline in the Company’s
stock price has decreased the exercise activity of option holders and we do not have sufficient historical exercise
data to provide a more reasonable basis upon which to estimate expected term.

Share-based compensation expense recognized in the Consolidated Statement of Operations for the year ended
December 31, 2008 is based on awards ultimately expected to vest, net of estimated forfeitures. SFAS 123R requires
forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures
differ from those estimates. Pre-vesting forfeitures for awards with monthly vesting terms were estimated to be 0%
in 2008 based on historical experience. The effect of pre-vesting forfeitures for awards with monthly vesting terms
has historically been negligible on the Company’s recorded expense. Pre-vesting forfeitures for awards with annual
vesting terms were estimated at 5% in 2008 based on historical employee turnover experience. The effect of the
restructurings has been excluded from the historical review of employee turnover. The Company’s determination of
fair value is affected by the Company’s stock price as well as a number of assumptions that require judgment. The
weighted-average fair values of options granted during the years ended December 31, 2008, 2007 and 2006,
estimated as of the grant date using the Black-Scholes option valuation model, were $2.86, $6.60 and $9.73,
respectively.

Tender Offer. On September 26, 2006, the Company completed a Tender Offer (Offer) to holders of
outstanding options to purchase its common stock under the 2003 Plan, 1992 Incentive Stock Plan (the 1992 Plan)
and 2001 Stock Option Plan, as amended (the 2001 Plan). The Offer was for holders of options under the 2003 Plan
to cancel their options in exchange for a lesser number of new options (at a two-for-one exchange ratio) to purchase
shares of the Company’s common stock issued under the 2003 Plan and for holders of options under the 1992 Plan
and 2001 Plan to cancel one-half of their options and amend their remaining options to purchase shares of the
Company’s common stock. The Offer was open to eligible employees and active consultants of the Company who
held options with an exercise price of $20.00 or higher per share as of September 25, 2006. Certain executives and
members of the Board of Directors were not eligible to participate in the Offer. Approximately 2.0 million options
were exchanged or amended resulting in approximately 1.0 million new or amended option grants and approx-
imately 1.0 million cancelled option grants at the completion of the Offer. New or amended options under the Offer
vest annually over a period of three years and have a weighted average exercise price of $10.90. Share based
compensation expense related to the Offer totaled approximately $8.7 million and is being amortized over 3 years
commencing on September 26, 2006.

A summary of the status of the Company’s stock options as of December 31, 2008 and of changes in options
outstanding under the plans during the year ended December 31, 2008 is as follows (in thousands, except for

Options outstanding at December 31, 2008 have a weighted average remaining contractual term of 3.9 years.

For the year ended December 31, 2008, share-based compensation expense related to stock options was
$3.7 million. As of December 31, 2008, there is approximately $3.0 million of unamortized compensation cost
related to stock options. Compensation cost associated with unvested stock option awards as of December 31, 2008
is expected to be recognized over a remaining weighted-average vesting period of 1.3 years. As of December 31,
2008, there are approximately 2.7 million options exercisable with a weighted average exercise price of $26.57 and
a weighted-average remaining contractual term of 3.4 years. The total intrinsic value, which is the amount (if any)
by which the exercise price was exceeded by the sale price of the Company’s common stock on the date of sale, of
stock option exercises during the years ended December 31, 2008, 2007, and 2006 was $13,000, $0.4 million and
$18.1 million, respectively. As of December 31, 2008 the total intrinsic value, of options outstanding and
exercisable was $0. Cash received from stock option exercises for the years ended December 31, 2008, 2007
and 2006 was $33,000, $0.6 million and $15.4 million, respectively.

On October 24, 2007, the Company entered into Stock Option Cancellation Agreements with certain of its
executive officers and directors, pursuant to which certain stock options previously granted to each such executive
officer or director, were cancelled in exchange for a nominal payment by the Company of $100 in the aggregate. The
Stock Option Cancellation Agreements indicated that other than such nominal payment, the applicable executive
officer or director had not received, and would not receive, any additional consideration in exchange for the
cancellation of such options. Accordingly, while each such executive officer or director will be eligible to receive
future equity grants in connection with the Company’s regular grant practices, no such executive officer or director
will receive any future equity award in exchange for the cancellation of such options. The Company recognized
approximately $0.4 million of compensation expense in conjunction with the cancellations.

Restricted Stock Units. Beginning in January 2006, certain employees are eligible to receive restricted stock
units under the 2003 Plan. In accordance with SFAS 123R, the fair value of restricted stock units is estimated based
on the closing sale price of the Company’s common stock on the Nasdaq Global Select Market on the date of
issuance. The total number of restricted stock awards expected to vest is adjusted by estimated forfeiture rates,
which has been estimated at 5% based on historical experience of restricted stock awards. As of December 31, 2008,
there is approximately $6.2 million of unamortized compensation cost related to restricted stock units, which is
expected to be recognized over a remaining weighted-average vesting period of 1.9 years. The restricted stock units,
at the election of eligible employees, may be subject to deferred delivery arrangement. For the year ended
December 31, 2008, share-based compensation expense related to restricted stock units was $4.3 million.

A summary of the status of the Company’s restricted stock units as of December 31, 2008, 2007, and 2006 and

Employee Stock Purchase Plan. The Company had reserved 725,000 shares of common stock for issuance
under the 1996 Employee Stock Purchase Plan, as amended (the Purchase Plan). The Purchase Plan had a six-month

contribution period with purchase dates of June 30 and December 31 each year. Effective January 1, 2006, the
Purchase Plan was amended such that the purchase price of common stock would be at 85% of the fair market value
per share of common stock on the date on which the shares are purchased. As of June 30, 2006, 640,000 shares had
been issued pursuant to the Purchase Plan. The Company recognized approximately $77,000 in share-based
compensation expense related to the purchase on June 30, 2006.

Effective July 1, 2006, the Company terminated the Purchase Plan as a result of a review of the Purchase Plan’s
effectiveness in providing long-term share ownership to the Company’s employees. In addition, the Purchase Plan
had an insufficient amount of shares available to allow full participation by employees.

Warrants. The Company has outstanding warrants to purchase 3,940 shares of common stock at $52.05 that

expire in December 2012.

NOTE 9. SIGNIFICANT COLLABORATIVE RESEARCH AND DEVELOPMENT AGREEMENTS

Dainippon Sumitomo Pharma Co., Ltd. On October 31, 2007, the Company entered into an exclusive
license agreement with Dainippon Sumitomo Pharma Co. Ltd. (DSP), under which the Company licensed rights to
indiplon to DSP and agreed to collaborate with DSP on the development and commercialization of indiplon in
Japan. Pursuant to the license agreement, among other things, the Company received an up-front license fee of
$20.0 million. The Company is also eligible to receive additional milestone payments upon specified future events
related to the development and commercialization of indiplon in Japan. Should all milestones be achieved, the
Company may be entitled to payments totaling an additional $115.0 million. Additionally, the Company is entitled
to royalties from DSP on future sales of indiplon in Japan. For the years ending December 31, 2008 and 2007, the
Company amortized into revenue $2.9 million and $0.5 million, respectively, of the upfront license fee under the
DSP agreement.

Pfizer.

In December 2002, the Company entered into an exclusive worldwide collaboration with Pfizer, Inc.
(Pfizer) to complete the clinical development of, and to commercialize, indiplon for the treatment of insomnia.
Under the terms of the agreement, Pfizer and Neurocrine collaborated in the completion of the indiplon Phase III
clinical program. During 2003, the Company received an upfront license fee of $100.0 million under the
collaboration.

For the year ended December 31, 2006, the Company recognized revenue of $6.6 million from the reim-
bursement of clinical development expenses under the Pfizer agreement. The Company also amortized into revenue
$6.5 million of the upfront license fee for the year ended December 31, 2006. The Company also recognized
$16.5 million from Pfizer during 2006 as a sales force allowance for the building and operation of the Company’s
200-person sales force.

On June 22, 2006 the Company and Pfizer agreed to terminate the collaboration and license agreements to
develop and co-promote indiplon effective December 19, 2006. As a result, the Company reacquired all worldwide
rights for indiplon capsules and tablets and is responsible for any further costs associated with development,
registration, marketing and commercialization of indiplon.

The Company obtained rights to indiplon pursuant to a 1998 Sublicense and Development Agreement with
DOV Pharmaceutical, Inc. (DOV) and is responsible for specified milestone payments and royalties to DOVon net
sales under the license agreement. Wyeth licensed the indiplon technology to DOV in 1998 in exchange for
milestone payments and royalties on future sales of indiplon. On February 26, 2004, the Company entered into

63

NEUROCRINE BIOSCIENCES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

several agreements with Wyeth and DOV pursuant to which the Company acquired Wyeth’s financial interest in
indiplon for approximately $95.0 million, consisting of $50.0 million in cash and $45.0 million of the Company’s
common stock. The agreements among the Company, Wyeth and DOV provide that the Company will make
milestone and royalty payments to DOV net of amounts that DOV would have been obligated to pay to Wyeth such
that the Company will retain all milestone, royalty and other payments on indiplon commercialization that would
have otherwise been payable to Wyeth, effectively decreasing the Company’s royalty obligation on sales of indiplon
from six percent to three and one-half percent. This transaction was recorded as a prepaid royalty and was to be
amortized over the commercialization period of indiplon, based primarily upon total estimated indiplon sales (see
Note 1 for a discussion of the impairment of the prepaid royalty). Additionally, the Company is responsible for
specified milestone payments up to $3.5 million to DOV Pharmaceutical under the license agreement, of which
$2.0 million was paid during 2004, $1.0 million was paid in 2007 and the balance is payable upon commercial-
ization of indiplon.

GlaxoSmithKline.

In July 2001, the Company announced a worldwide collaboration with GlaxoSmithKline
(GSK) to develop and commercialize CRF antagonists for psychiatric, neurological and gastrointestinal diseases.
Under the terms of this agreement, the Company and GSK will conduct a collaborative research program for up to
five years and collaborate in the development of Neurocrine’s current lead CRF compounds, as well as novel
back-up candidates and second generation compounds identified through the collaborative research. In addition, the
Company will be eligible to receive milestone payments as compounds progress through the research and
development process, royalties on future product sales and co-promotion rights in the U.S. under some conditions.
GSK may terminate the agreement at its discretion upon prior written notice to the Company. In such event, the
Company may be entitled to certain payments and all product rights would revert to Neurocrine. For each of the
years ended December 31, 2008, 2007 and 2006, the Company recognized $1.0 million, $0.1 million and
$9.1 million, respectively, in revenue under the GSK agreement. The sponsored research portion of this collab-
oration agreement ended in 2005.

NOTE 10.

INCOME TAXES

On July 13, 2006, the FASB issued FASB Interpretation No. 48 (FIN 48), “Accounting for Uncertainty in
Income Taxes, an interpretation of FASB No. 109”. Under FIN 48, the impact of an uncertain income tax position on
the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon
audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a
50% likelihood of being sustained. Additionally, FIN 48 provides guidance on derecognition, classification, interest
and penalties, accounting in interim periods, disclosure and transition.

The Company adopted the provisions of FIN 48 on January 1, 2007. There were no unrecognized tax benefits
as of the date of adoption. As a result of the implementation of FIN 48, the Company did not recognize an increase in
the liability for unrecognized tax benefits. There are no unrecognized tax benefits included in the balance sheet that
would, if recognized, affect the effective tax rate. The adoption of FIN 48 did not impact the Company’s financial
condition, results of operations or cash flows.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax
expense. The Company had no accrual for interest or penalties on the Company’s balance sheets at December 31,
2007 and at December 31, 2008, and has not recognized interest and/or penalties in the statement of operations for
the year ended December 31, 2008.

The Company is subject to taxation in the United States and various state jurisdictions. The Company’s tax
years for 1993 and forward are subject to examination by the United States and California tax authorities due to the
carry forward of unutilized net operating losses and R&D credits.

At December 31, 2008, the Company had net deferred tax assets of $69.3 million. Due to uncertainties
surrounding the Company’s ability to generate future taxable income to realize these assets, a full valuation has

64

NEUROCRINE BIOSCIENCES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

been established to offset the net deferred tax asset. Additionally, the future utilization of the Company’s net
operating loss and research and development credit carry forwards to offset future taxable income may be subject to
an annual limitation, pursuant to Internal Revenue Code Sections 382 and 383, as a result of ownership changes that
may have occurred previously or that could occur in the future. Although the Company determined that an
ownership change had not occurred through January 31, 2007, it is possible that an ownership change occurred
subsequent to that date. The Company has not completed an update of its Section 382 analysis subsequent to
January 31, 2007. Until this analysis has been updated, the Company has removed the deferred tax assets for net
operating losses of $227.2 million and research and development credits of $38.8 million generated through 2008
from its deferred tax asset schedule and has recorded a corresponding decrease to its valuation allowance. Due to the
existence of the valuation allowance, future changes in the Company’s unrecognized tax benefits will not impact the
Company’s effective tax rate.

At December 31, 2008, the Company had Federal and California income tax net operating loss carry forwards
of approximately $587.0 million and $488.9 million, respectively. The Federal and California tax loss carry
forwards will begin to expire in 2010 and 2012, unless previously utilized. In addition, the Company has Federal and
California research and development tax credit carry forwards of $26.8 million and $18.5 million, respectively. The
Federal research and development tax credit carry forwards began expiring in 2007 and will continue to expire
unless utilized. There were $186,000 of Federal research and development tax credit carryforwards that have
expired through 2008. The California research and development tax credit carryforwards carry forward indefinitely.
The Company also has Federal Alternative Minimum Tax credit carryforwards of approximately $256,000, which
will carry forward indefinitely. At December 31, 2008, approximately $88.3 million of the net operating loss carry
forwards relate to stock option exercises, which will result in an increase to additional paid-in capital and a decrease
in income taxes payable at the time when the tax loss carryforwards are utilized.

Significant components of the Company’s deferred tax assets as of December 31, 2008 and 2007 are listed
below. A valuation allowance of $69.3 million and $65.8 million at December 31, 2008 and 2007, respectively, has
been recognized to offset the net deferred tax assets as realization of such assets is uncertain. Amounts are shown in
thousands as of December 31, of the respective years (in thousands):

NOTE 11. RETIREMENT PLAN

The Company has a 401(k) defined contribution savings plan (401(k) Plan). The 401(k) Plan is for the benefit
of all qualifying employees and permits voluntary contributions by employees up to 60% of base salary limited by
the IRS-imposed maximum. The Company matches 50% of employee contributions up to 6% of eligible
compensation, with cliff vesting over four years. Employer contributions were $430,000, $690,000 and
$1,152,000 for the years ended December 31, 2008, 2007, and 2006, respectively.

NOTE 12. LEGAL MATTERS

On June 19, 2007, Construction Laborers Pension Trust of Greater St. Louis filed a purported class action
lawsuit in the United States District Court for the Southern District of California under the caption Construction
Laborers Pension Trust of Greater St. Louis v. Neurocrine Biosciences, Inc., et al., 07-cv-1111-IEG-RBB. On
June 26, 2007, a second purported class action lawsuit with similar allegations was also filed. On October 16, 2007,
both lawsuits were consolidated into one purported class action under the caption In re Neurocrine Biosciences, Inc.
Securities Litigation, 07-cv-1111-IEG-RBB. The court also selected lead plaintiffs and ordered them to file a
consolidated complaint. On November 30, 2007, lead plaintiffs filed the Consolidated Amended Complaint (CAC),
which alleged, among other things, that the Company and certain of its officers and directors violated federal
securities laws by making allegedly false and misleading statements regarding the progress toward FDA approval
and the potential for market success of indiplon in the 15 mg dosage unit. On January 11, 2008, the Company and
the individual defendants filed a motion to dismiss the CAC. Following a hearing on April 22, 2008, the court
granted the motion to dismiss but gave the lead plaintiffs leave to file a second amended complaint. On June 11,
2008, the lead plaintiffs filed the Second Consolidated Amended Complaint (SAC). On July 8, 2008, the Company
and the individual defendants filed a motion to dismiss the SAC. The court granted the motion to dismiss on
September 23, 2008 but gave lead plaintiffs further leave to file a Third Consolidated Amended Complaint (TAC).
On October 23, 2008, rather than filing a TAC, the lead plaintiffs filed a Notice of Election to Stand on the SAC,
requesting that the court enter a final judgment dismissing the matter. On November 3, 2008, the court entered a
final judgment dismissing the matter with prejudice. On December 31, 2008, the time elapsed for lead plaintiffs to
appeal the court’s final judgment to the Ninth Circuit Court of Appeals.

In addition, on June 25, 2007, a shareholder derivative complaint was filed in the Superior Court of the State of
California for the County of San Diego by Ralph Lipeles under the caption, Lipeles v. Lyons. The complaint was
brought purportedly on the Company’s behalf against certain current and former officers and directors and alleges,
among other things, that the named officers and directors breached their fiduciary duties by directing the Company
to make allegedly false statements about the progress toward FDA approval and the potential for market success of
indiplon in the 15mg dosage unit. All proceedings in this matter were stayed pending resolution of the motion to
dismiss the federal class action lawsuit. Following the dismissal of the federal class action lawsuit, on November 19,

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

2008, the plaintiff in the derivative action filed a request for dismissal of the derivative action. The court entered an
order dismissing the derivative action without prejudice on November 20, 2008.

FINANCIAL DISCLOSURE

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be
disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the timelines
specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated
and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as
appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure
controls and procedures, management recognized that any controls and procedures, no matter how well designed
and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a
reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-
benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and with the
participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the
effectiveness of the design and operation of our disclosure controls and procedures as of the end of the year covered
by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our
disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

Internal control over financial reporting refers to the process designed by, or under the supervision of, our
Chief Executive Officer and Chief Financial Officer, and effected by our board of directors, management and other
personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles, and
includes those policies and procedures that:

(1) Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the

transactions and dispositions of our assets;

(2) Provide reasonable assurance that transactions are recorded as necessary to permit preparation of
financial statements in accordance with generally accepted accounting principles, and that our receipts and
expenditures are being made only in accordance with authorization of our management and directors; and

(3) Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition,

use or disposition of our assets that could have a material effect on the financial statements.

Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting
objectives because of its inherent limitations. Internal control over financial reporting is a process that involves
human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human
failures. Internal control over financial reporting also can be circumvented by collusion or improper management
override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on
a timely basis by internal control over financial reporting. However, these inherent limitations are known features of
the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not
eliminate, this risk. Management is responsible for establishing and maintaining adequate internal control over
financial reporting for the company.

Management has used the framework set forth in the report entitled Internal Control-Integrated Framework
published by the Committee of Sponsoring Organizations of the Treadway Commission, known as COSO, to
evaluate the effectiveness of our internal control over financial reporting. Based on this assessment, management
has concluded that our internal control over financial reporting was effective as of December 31, 2008. Ernst &
Young, LLP, our independent registered public accounting firm, has issued an attestation report on our internal
control over financial reporting, which is included herein.

There has been no change in our internal control over financial reporting during our most recent fiscal quarter
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
on Internal Control Over Financial Reporting

The Board of Directors and Stockholders
Neurocrine Biosciences, Inc.

We have audited Neurocrine Biosciences, Inc.’s internal control over financial reporting as of December 31,
2008, based on criteria established in Internal Control-Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (the COSO criteria). Neurocrine Biosciences’ manage-
ment is responsible for maintaining effective internal control over financial reporting, and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Report on Internal Control
Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over
financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s
assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, Neurocrine Biosciences, Inc. maintained, in all material respects, effective internal control over

financial reporting as of December 31, 2008 based, on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets as of December 31, 2008 and 2007, and the related consolidated
statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended
December 31, 2008 of Neurocrine Biosciences, Inc. and our report dated February 2, 2009 expressed an unqualified
opinion thereon.
