                           Orchid BioSciences, Inc.
                             303 College Road East
                              Princeton, NJ 08540

                                 ------------

                                PROXY STATEMENT

                                 ------------

                              GENERAL INFORMATION

   This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Orchid BioSciences, Inc. (the "Company"), a Delaware
corporation, of proxies, in the accompanying form, to be used at the Annual
Meeting of Stockholders to be held at the Princeton Marriott Forrestal
Village, 201 Village Boulevard, Princeton, New Jersey 08540 on Tuesday, June
12, 2001 at 10:00 a.m., and any adjournments thereof (the "Meeting").

   If the stockholder specifies in the proxy how the shares are to be voted,
they will be voted as specified.

   If the enclosed form of proxy is properly signed and returned or a proxy is
voted electronically or by telephone, the shares represented thereby will be
voted accordingly. If no choice is specified, the shares will be voted:

  .  FOR the election of Sidney M. Hecht as a Class I Director;

  .  FOR the proposal to increase the aggregate number of shares of the
     Company's common stock, $.001 par value per share (the "Common Stock"),
     authorized for issuance under the Company's 2000 Employee, Director, and
     Consultant Stock Plan to 4,500,000 shares;

  .  FOR the proposal to amend the Company's Restated Certificate of
     Incorporation; and

  .  FOR the ratification of the appointment of KPMG LLP as the Company's
     independent public accountants for the fiscal year ending December 31,
     2001.

   Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before its use by delivering to the Company a written
notice of revocation or a duly executed proxy bearing a later date. Any
stockholder who has executed a proxy but is present at the Meeting, and who
wishes to vote in person, may do so by revoking his or her proxy as described
in the preceding sentence. Shares represented by valid proxies in the form
enclosed, received in time for use at the Meeting and not revoked at or prior
to the Meeting, will be voted at the Meeting. The presence, in person or by
proxy, of the holders of a majority of the outstanding shares of the Company's
Common Stock is necessary to constitute a quorum at the Meeting. Votes of
stockholders of record who are present at the meeting in person or by proxy,
abstentions, and broker non-votes (as defined below) are counted as present or
represented at the meeting for purposes of determining whether a quorum
exists.

   Nominees for election as Directors at the meeting will be elected by a
plurality of the votes of the shares present in person or represented by proxy
at the meeting. Withholding authority to vote for a nominee for Director will
have no effect on the outcome of the vote.

   For the proposals (i) to increase the aggregate number of shares of the
Company's Common Stock reserved for issuance under the Company's 2000
Employee, Director, and Consultant Stock Plan by 3,000,000 shares and (ii) to
ratify the appointment of KPMG LLP as the Company's independent public
accountants for the fiscal year ending December 31, 2001, the affirmative vote
of a majority of shares of Common Stock voted affirmatively or negatively at
the Meeting on the matter is necessary for approval. Abstentions with respect
to each of these two proposals have no effect on the outcome of the vote.

                                       1


   For the proposal to amend the Company's Restated Certificate of
Incorporation to increase the aggregate number of shares of Common Stock
authorized for issuance by the Company from 50,000,000 shares to 100,000,000
shares, the affirmative vote of the holders of at least the majority of the
outstanding Common Stock of the Company entitled to vote on this matter is
required for approval under Delaware law. Because abstentions are treated as
shares present or represented and entitled to vote, abstentions with respect to
this proposal have the same effect as a vote against the proposal.

   If you hold your shares of Common Stock through a broker, bank or other
representative, generally the broker or your representative may only vote the
Common Stock that it holds for you in accordance with your instructions.
However, if it has not timely received your instructions, the broker or your
representative may vote on certain matters for which it has discretionary
voting authority. If a broker or your representative does not have
discretionary voting authority on a certain matter, the broker may not vote on
your behalf with respect to the matter, which is considered a "broker non-vote"
on that matter. As to the proposals relating to the stock option plan and the
ratification of independent public accountants, which each require an
affirmative vote of the majority of votes cast affirmatively or negatively at
the Meeting, broker non-votes will have no effect on the outcome of the vote.
As to the proposal to amend the Company's Restated Certificate of
Incorporation, which requires an affirmative vote of a majority of the
Company's outstanding Common Stock, broker non-votes have the same effect as a
vote against the proposal. Therefore, we urge you to vote your shares at your
earliest possible convenience.

   The close of business on April 16, 2001 has been fixed as the record date
for determining the stockholders entitled to notice of and to vote at the
Meeting. As of the close of business on April 16, 2001, the Company had
33,470,830 shares of Common Stock outstanding and entitled to vote. Holders of
Common Stock are entitled to one vote per share on all matters to be voted on
by stockholders.

   The cost of soliciting proxies, including expenses in connection with
preparing and mailing this Proxy Statement, will be borne by the Company. In
addition, the Company will reimburse brokerage firms and other persons
representing beneficial owners of Common Stock of the Company for their
expenses in forwarding proxy materials to such beneficial owners. Solicitation
of proxies by mail may be supplemented by telephone, telegram, facsimile and
personal solicitation by certain officers or employees of the Company as well
as by a professional solicitor. The Company has retained D.F. King & Co., Inc.
to solicit the majority of proxies for a fee of approximately $7,500 as well as
reimbursement for certain expenses incurred by them in connection with their
services, all of which will be paid by the Company. In addition, the Company
may request banks, brokers, and other custodians, nominees and fiduciaries to
solicit customers of theirs who have shares of the Company registered in the
name of the nominee. The Company will reimburse any such persons for their
reasonable out-of-pocket expenses.

   This Proxy Statement and the accompanying proxy card are being mailed on or
about May 11, 2001 to all stockholders entitled to notice of and to vote at the
Meeting.

   The Annual Report to Stockholders for the fiscal year ended December 31,
2000 is being mailed to the stockholders with this Proxy Statement, but does
not constitute a part hereof.

                                       7


fair market value of the Common Stock on the grant date. Options issued under
the Plans typically vest in 36 equal monthly installments over a period of
three years or 48 equal monthly installments over a period of four years, in
each case, commencing on the last day of the month in which the option was
granted. Each option terminates on the earlier of (i) ten years after the date
of grant or (ii) the date that is three months after the optionee ceases to
serve as a Director (or twelve months, if service ends due to death or
disability). The exercisability of options granted to Directors under the Plans
will be accelerated upon an acquisition or a change of control of the Company.

(1)  The exercise price on the date of grant was equal to 100% of the fair
     market value on the date of grant.
(2)  The 5% and 10% assumed rates of appreciation are suggested by rules of the
     Securities and Exchange Commission and do not represent the Company's
     estimate or projection of the future common stock price. There can be no
     assurance of the future Common Stock price.
     The amounts shown in this table represent hypothetical gains that could be
     achieved for the respective options if exercised at the end of the option
     term. These gains are based on assumed rates of stock appreciation of 5%
     and 10% compounded annually from the date the respective options were
     granted to their expiration date. The gains shown are net of the option
     exercise price, but do not include deductions for taxes or other expenses
     associated with the exercise. Actual gains, if any, on stock option
     exercises will depend on the future performance of the Common Stock, the
     optionee's continued employment through the option period and the date on
     which the options are exercised.
(3)  The option will vest only when the price of the Company's Common Stock
     exceeds $16 within the period between 6 and 18 months immediately
     following the Company's initial public offering and is sustained for 45
     trading days thereafter (trailing 45-day average) and accelerates if any
     acquisition of the Company occurs in which the acquiring company exchanges
     stock having a value of at least $16 per share or pays $16 per share for
     each share of the Company's Common Stock.
(4)  The option will vest only when the price of the Company's stock exceeds
     $32 within the period between 6 and 30 months immediately following the
     Company's initial public offering and is sustained for 45 trading days
     thereafter (trailing 45-day average) and accelerates if any acquisition of
     the Company occurs in which the acquiring company exchanges stock having a
     value of at least $32 per share or pays $32 per share for each share of
     the Company's Common Stock.
(5)  The option will vest only when the price of the Company's Common Stock
     exceeds $64 within the period between 6 and 42 months immediately
     following the Company's initial public offering and is sustained for 45
     trading days thereafter (trailing 45-day average) and accelerates if any
     acquisition of the Company occurs in which the acquiring Company exchanges
     stock having a value of at least $64 per share or pays $64 per share for
     each share of the Company's Common Stock.
(6)  The option will vest only when the price of the Company's stock exceeds

    Stock.
(8) The option will vest only when the price of the Company's stock exceeds $64

Corporate 401(k) Plan

   The Company sponsors a 401(k) plan covering employees who meet certain
defined requirements. Under the terms of the Company's 401(k) plan,
participants may elect to make contributions on a pre-tax and after-tax basis,
subject to certain limitations under the Internal Revenue Code and the Company
may match a percentage of employee contributions, on a discretionary basis, as
determined by the Company's Board of Directors. The Company may make other
discretionary contributions to the 401(k) plan, although pursuant to a
determination by the Company's Board of Directors, the Company currently
matches 50% of the first 4% of employee contribution.

Executive Deferred Compensation Plan

   The Company has established an executive deferred compensation plan, which
became effective on February 3, 1999. It was established primarily for the
purpose of providing life and disability insurance and retirement benefits as
well as deferred compensation for the Company's executive officers, Directors
and highly compensated employees. Participants in the plan are permitted to
defer receipt of, and income taxation on, up to 50% of their regular base
salary and all or any portion of any bonus until they terminate their
employment with the Company. Under the terms of the plan, the Company will also
provide an annual cash allowance to each eligible participant to pay the
premiums for their supplemental life and disability insurance.

Employment Contracts, Termination of Employment and Change-in-Control
Arrangements

   The Company entered into a three year employment agreement with Dale R.
Pfost, Ph.D., effective as of January 2000, to serve as the Company's President
and Chief Executive Officer at an annual base salary of $350,000. Under the
terms of his employment agreement, Dr. Pfost is entitled to receive an annual
bonus of up to 25% of his base salary to be awarded based upon the Company's
achievement of specific performance milestones. If the Board of Directors
determines in good faith that the Company's performance has exceeded such
milestones, it may increase Dr. Pfost's bonus to up to 35% of his base salary.
The Company also contributes an additional amount equal to 10% of Dr. Pfost's
annual salary to a non-qualified retirement plan for the sole benefit of Dr.
Pfost. In addition, upon execution of the agreement, the Company issued to Dr.
Pfost options to purchase an aggregate of 730,000 shares of the Company's
Common Stock. Of these 730,000 options, options to purchase 100,000 shares were
previously granted in December 1999 with an exercise price of $1.25 per share.
The remaining 630,000 options have an exercise price of $6.00 per share. A
total of 360,000 of these newly issued options with $6.00 per share exercise
prices will vest if and when the price of the Company's Common Stock exceeds
certain specified levels for 45 consecutive trading days. The Company may
terminate the agreement with or without cause at any time. If the Company
terminates Dr. Pfost's employment for cause, the Company is only obligated to
pay him severance equal to his accrued base salary up to the date of
termination. If the Company terminates Dr. Pfost's employment without cause, or
if Dr. Pfost terminates his employment for good reason, the Company is
obligated to pay Dr. Pfost a severance amount equal to his annual base salary
and benefits for an eighteen month period following the effective date of
termination. The Company must provide Dr. Pfost with notice of termination in
advance of the effective termination date. The advance notice period ranges
from six to eighteen months, depending on the timing of the effective date of
the termination.

   The Company entered into a three year employment agreement with Donald R.
Marvin, effective as of January 2000, to serve as the Company's Senior Vice
President, Corporate Development, Chief Operating Officer and Chief Financial
Officer at an annual base salary of $275,000. Under the terms of his employment
agreement, Mr. Marvin is entitled to receive an annual bonus of up to 25% of
his base salary to be awarded based upon the achievement of specific
performance milestones. If the Board of Directors determines in good faith that
the Company's performance has exceeded such milestones, it may increase Mr.
Marvin's bonus to up to 35% of his base salary. In addition, upon execution of
the agreement, the Company issued to Mr. Marvin options to purchase an
aggregate of 557,000 shares of the Company's Common Stock. Of these 557,000
options, options to purchase 67,000 shares were previously granted in December
1999 at an exercise price of $1.25 per share. The remaining 490,000 options
have an exercise price of $6.00 per share. A total of 240,000 of these newly
issued options with $6.00 per share exercise prices will vest if and when the
price of the Company's stock exceeds certain specified levels for 45
consecutive trading days. The Company also contributes an additional amount
equal to 5% of Mr. Marvin's annual salary to a non-qualified retirement plan
for the sole benefit of Mr. Marvin. The Company may terminate the agreement
with or without cause at any time. If the Company terminates Mr. Marvin's
employment for cause, the Company is only obligated to pay him severance equal
to his accrued base salary up to the date of termination. If the Company
terminates Mr. Marvin's employment without cause, or if Mr. Marvin terminates
his employment for good reason, the Company is obligated to pay Mr. Marvin a
severance amount equal to his annual base salary and benefits for an eighteen
month period following the effective date of termination. The Company must
provide Mr. Marvin with

                                       12


notice of termination in advance of the effective termination date. The advance
notice period ranges from six to eighteen months, depending on the timing of
the effective date of the termination.

   The outstanding option agreements issued under the Plans provide for
acceleration of the vesting of the options granted upon or in connection with a
change in control.

Performance Graph

   The following graph compares the annual percentage change in the Company's
cumulative total stockholder return on its Common Stock during a period

        REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
                           ON EXECUTIVE COMPENSATION

   This report on executive compensation is provided by the Compensation
Committee of the Board of Directors (the "Compensation Committee") to assist
stockholders in understanding their objectives and procedures in establishing
the compensation of the Company's executive officers and describes the bases
on which 2000 compensation determinations were made by the Compensation
Committee. The Compensation Committee of the Board of Directors in 2000 was
composed of Drs. Sidney M. Hecht, Jeremy M. Levin, Mr. Samuel D. Isaly and Ms.
Anne M. VanLent, none of whom have ever been officers or employees of the
Company. Ms. VanLent resigned from the Board of Directors and the Compensation
Committee on March 13, 2001. The committee is responsible for establishing the
Company's compensation programs for all employees, including the Company's
executive officers. For executive officers, the committee evaluates
performance and determines compensation policies and levels.

Compensation Philosophy

   The Compensation Committee believes that compensation of the Company's
executive officers should:

  .  Encourage creation of stockholder value and achievement of strategic
     corporate objectives;

  .  Integrate compensation with the Company's annual and long-term corporate
     objectives and strategy, and focus executive behavior on the fulfillment
     of those objectives;

  .  Provide a competitive total compensation package that enables the
     Company to attract and retain, on a long-term basis, high caliber
     personnel;

  .  Provide total compensation opportunity that is competitive with
     companies in the biopharmaceutical and biotechnology industries, taking
     into account relative company size, performance and geographic location
     as well as individual responsibilities and performance;

  .  Align the interests of management and stockholders and enhance
     stockholder value by providing management with longer term incentives
     through equity ownership by management; and

  .  Provide fair compensation consistent with internal compensation
     programs.

Salary. Salary levels are largely determined through comparisons with
companies of similar headcount and market capitalizations or complexity in the
biopharmaceutical and biotechnology industries. Actual salaries are based on
individual performance contributions within a competitive salary range for
each position that is established through job evaluation of responsibilities
and market comparisons. The Compensation Committee, on the basis of its
knowledge of executive compensation in the industry, believes that the
Company's salary levels for the executive officers are at a level that the
Compensation Committee, at the time such salary

                                      14


determinations were made, considered to be reasonable and necessary given the
Company's financial resources and the stage of its development. In December
2000, the Compensation Committee set annual salaries for 2001. The Compensation
Committee reviews salaries on an annual basis, with the next annual review
scheduled to occur in December 2001. At such time, the Compensation Committee
may change each executive officer's salary based on the individual's
contributions and responsibilities over the prior 12 months and any change in
median comparable company pay levels.

Cash Bonus. The Compensation Committee annually reviews each executive
officer's bonus, the aggregate bonus pool for the Company and the bonus
allocations by employee position. Payment of a cash bonus is tied to the
accomplishment of specific corporate milestones set at the beginning of the
year and to each individual officer's year-end performance review.

Equity Incentives. The Company intends that certain compensation paid to
management in 2000, including stock options, be exempt from the limitations on
deductibility under Section 162(m) of the Internal Revenue Code. The
Compensation Committee believes that by providing those persons who have
substantial responsibility for the management and growth of the Company with an
opportunity to increase their ownership of Company stock, the best interest of
stockholders and executive officers will be closely aligned. Therefore,
executive officers are eligible to receive stock options when the Compensation
Committee performs its annual salary review; although the Compensation
Committee, at its discretion, may grant options at other times in recognition
of exceptional achievements. Executives receive value from these grants only if
the Company's Common Stock appreciates over the long term. Option grants
generally vest over four years and are made at 100% of fair market value on the
date of grant. The number of shares underlying stock options granted to
executive officers is based on competitive practices in the industry as
determined by independent surveys and the Compensation Committee's knowledge of
industry practice. The Board granted options to purchase an aggregate of
1,120,000 shares of the Company's common stock to the Company's executive
officers in 2000, 600,000 of which will vest upon achievement of performance
milestones with respect to the price per share of the Company's Common Stock.

                      CHIEF EXECUTIVE OFFICER COMPENSATION

   Dr. Dale R. Pfost is the President, Chief Executive Officer and Chairman of
the Board of Directors of the Company. His salary and bonus for fiscal year
ended 2000 are consistent with the criteria described above and with the
Compensation Committee's evaluation of his overall leadership and management of
the Company. In setting Dr. Pfost's compensation for 2000, the Compensation
Committee considered Dr. Pfost's performance in advancing the development and
growth of the Company and the Company's achievement of specific corporate
objectives. Highlights of Dr. Pfost's strategic contributions include the
following: the acquisition of GeneScreen, Inc.; substantial capital fund
raising in a private placement financing which the Company completed in January
2000 that raised an aggregate of approximately $74 million and the completion
of its initial public offering in May, that raised approximately $48 million;
the establishment of the Company's European office in the United Kingdom in
July; the establishment of a number of commercial relationships with several
major pharmaceutical partners, and the launch of SNP Identification Technology,
the Company's method of performing genotyping services. The Compensation
Committee determined that these achievements were important to the Company's
future growth and could assist the Company in enhancing stockholder value and,
accordingly, determined to reward Dr. Pfost for his efforts on behalf of the
Company. In addition, the committee also granted Dr. Pfost options, exercisable
at the fair market value on the date of grant, to purchase shares of the
Company's Common Stock. Dr. Pfost's compensation for 2000 is set forth in the
Summary Compensation Table. The Compensation Committee has set Dr. Pfost's
annual salary for 2001 at $365,750.

                           FEDERAL TAX CONSIDERATIONS

   Section 162(m) of the Internal Revenue Code (the "Code") limits the Company
to a deduction for federal income tax purposes of no more than $1 million of
compensation paid to certain executive officers in a taxable year. Compensation
above $1 million may be deducted if it is "performance-based compensation"
within the meaning of Section 162(m).

                                       15


   The statute containing this law and the applicable Treasury regulations
offer a number of transitional exceptions to this deduction limit for pre-
existing compensation plans, arrangements and binding contracts. As a result,
the committee believes that at the present time it is quite unlikely that the
compensation currently paid or awarded to any executive officer will be subject
to Section 162(m) deduction limits. Therefore, the Compensation Committee has
not yet established a policy for determining which forms of incentive
compensation awarded to its executive officers shall be designed to qualify as
"performance-based compensation." The Compensation Committee intends to
continue to evaluate the effects of the statute and any applicable Treasury
regulations and to avoid the limitations of Section 162(m) in the future to the
extent consistent with the Company's best interests.

                                   CONCLUSION

   Through the plans described above, a significant portion of the Company's
compensation program and Dr. Pfost's compensation are contingent on the
Company's performance, and realization of benefits is closely linked to return
on investment and the long term growth in shareholder value. The Company
remains committed to this philosophy of pay for performance, recognizing that
the competitive market for talented executives and the volatility of the
Company's business may result in highly variable compensation for a particular
time period.

                           REPORT OF AUDIT COMMITTEE

   The Audit Committee of the Board of Directors, which consists entirely of
Directors who meet the independence and experience requirements of The Nasdaq
National Stock Market, has furnished the following report:

   The Audit Committee assists the Board in overseeing and monitoring the
integrity of the Company's financial reporting process, its compliance with
legal and regulatory requirements and the quality of its internal and external
audit processes. The role and responsibilities of the Audit Committee are set
forth in a written Charter adopted by the Board of Directors (the "Charter"),
which is attached as Appendix A to this Proxy Statement. The Audit Committee
reviews and reassesses the Charter annually and recommends any changes to the
Board for approval. The Audit Committee is responsible for overseeing the
Company's overall financial reporting process. In fulfilling its
responsibilities for the financial statements for fiscal year 2000, the Audit
Committee took the following actions:

  .  Reviewed and discussed the audited financial statements for the fiscal
     year ended December 31, 2000 with management and KPMG LLP ("KPMG"), the
     Company's independent auditors;

  .  Discussed with KPMG the matters required to be discussed by Statement on
     Auditing Standards No. 61 relating to the conduct of the audit; and

  .  Received written disclosures and the letter from KPMG regarding its
     independence as required by Independence Standards Board Standard No. 1.
     The Audit Committee further discussed with KPMG their independence. The
     Audit Committee also considered the status of pending litigation,
     taxation matters and other areas of oversight relating to the financial
     reporting and audit process that the Committee determined appropriate.

                                       16


   Based on the Audit Committee's review of the audited financial statements
and discussions with management and KPMG, the Audit Committee recommended to
the Board that the audited financial statements be included in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 2000 for
filing with the Securities and Exchange Commission.

                                          Members of the Audit Committee

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

   Since January 2000, there has not been nor is there currently proposed, any
transaction or series of similar transactions to which the Company was or is to
be a party in which the amount involved exceeded or exceeds $60,000 and in
which any director, executive officer, holder of more than 5% of the Company's
common stock or any member of the immediate family of any of the foregoing
persons had or will have a direct or indirect material interest other than the
transactions described below.

   In December 1997, the Company entered into a License and Option Agreement
with Sarnoff Corporation pursuant to which Sarnoff granted rights to the
Company under certain technology for the research, development and sale of
products and services in the field of combinatorial chemistry and in vitro
diagnostics. As part of the Company's transition from our historical business
model based on microfluidics technologies to the Company's current business
model based on the Company's SNP scoring technologies, on April 13, 2000, the
Company amended its License and Option Agreement with Sarnoff pursuant to which
the Company mutually agreed to convert its existing licenses in each relevant
field from an ongoing royalty-based license to a license paid in full. In
addition, the Company exercised and fully paid up its exclusive option to the
genomics and research products fields. The Company waived its exclusivity (but
retained its non-exclusive licenses) to the fields of high-throughput screening
and cell-based assay fields. Under the terms of this amendment, in lieu of all
its future cash payment, research funding, potential royalty payment and stock
issuance obligations, the Company paid a one-time payment to Sarnoff in the
aggregate amount of approximately $3.0 million and issued to Sarnoff 250,000
shares of its Common Stock and a warrant to purchase 75,000 shares of its
common stock at $8.00 per share on April 13, 2000. Upon payment of this
consideration, the Company received exclusive licenses in the fields formerly
covered by options under its License and Option Agreement. On February 2, 2000,
the Company also issued 100,000 shares of Common Stock to Sarnoff as an advance
on the issuances which would be owed in December 2000 for the two option fields
previously exercised under the License and Option Agreement. The Sarnoff
agreement has a term which continues until terminated by mutual agreement or by
Sarnoff, if the Company fails to make any payment when due unless the failure
is cured within 90 days of notice from Sarnoff.

   In December 1999 and January 2000, the Company completed a private placement
in which it issued 18,881,563 shares of Series E convertible preferred stock,
which amount includes the shares issued in connection with the acquisition of
GeneScreen. INVESCO Global Health Sciences Fund, a five percent beneficial
stockholder, through each of Global Health Sciences Fund and Pirate Ship & Co.,
purchased an aggregate of 645,189 shares of Series E convertible preferred

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

   Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
Directors and officers, and persons who own more than 10% of the Common Stock,
to file with the Securities and Exchange Commission (the "SEC") initial reports
of beneficial ownership and reports of changes in beneficial ownership of the
Common Stock and other equity securities of the Company. Officers, Directors
and greater than 10% beneficial owners are required by SEC regulation to
furnish the Company with copies of all Section 16(a) forms they file.

   To the Company's knowledge, based solely on review of the copies of such
reports furnished to the Company and written representations that no other
reports were required, during the fiscal year ended December 13, 2000 all
Section 16(a) filing requirements applicable to its officers, Directors and
greater than 10% beneficial owners were met, except that (i) due to a clerical
error, initial reports of ownership were filed late by Robert M. Tien, Sidney
M. Hecht, Samuel D. Isaly, Dale R. Pfost, Anne M. VanLent, Donald R. Marvin,
Ernest Mario, George Poste and Jeremy M. Levin, (ii) one report, covering three
transactions, was filed late by Dale R. Pfost, (iii) one report, covering one
transaction, was filed late by Donald R. Marvin and (iv) one report, covering
two transactions, was filed late by Robert M. Tien.

   An Annual Statement of Beneficial Ownership on Form 5 is not required to be
filed if there are no previously unreported transactions or holdings to report.
Nevertheless, the Company is required to disclose the names of Directors,
officers and 10% shareholders who did not file a Form 5 unless the Company has
obtained a written statement that no filing is required. At the date of this
proxy statement, the Company had not received a written statement from Anne M.
VanLent, a former Director, who has not filed a Form 5.

                             ELECTION OF DIRECTORS

                                (Notice Item 1)

   The Company's Restated Certificate of Incorporation provides for a staggered
Board of Directors. The Board of Directors currently consists of eight members
for the coming year and is divided into three classes. At the meeting, a
director will be elected to hold office for three years and until his successor
is elected and qualified. Dr. Sidney M. Hecht, who is presently serving as a
Director, has been nominated for re-election by the Board of Directors. Unless
the enclosed proxy withholds authority to vote for Dr. Hecht or is a broker
non-vote, the shares represented by such proxy will be voted for the election
of Dr. Hecht as the Board's nominee.

   The Board of Directors has voted (i) to maintain the size of the Board of
Directors at eight members and (ii) to nominate Sidney M. Hecht for election at
the Meeting for a term of three years to serve until the 2004 annual meeting of
stockholders, and until his successor is elected and qualified. The Class II
Directors (Drs. Tien, Levin and Mario) and the Class III Directors (Drs. Pfost,
Poste and Mr. Isaly) will serve until the annual meetings of stockholders to be
held in 2002 and 2003, respectively, and until their respective successors have
been elected and qualified.

   Unless authority to vote for the nominee named above is withheld, the shares
represented by the enclosed proxy will be voted FOR Dr. Hecht. In the event
that Dr. Hecht shall become unable or unwilling to serve, the shares
represented by the enclosed proxy will be voted for the election of such other
person as the Board of Directors may recommend in his place. The Board has no
reason to believe that Dr. Hecht will be unable or unwilling to serve.

   A plurality of the votes of the shares present in person or represented by
proxy at the Meeting is required to elect the nominee as a Director.

   THE BOARD OF DIRECTORS RECOMMENDS THE ELECTION OF DR. HECHT AS A CLASS I
DIRECTOR, AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR THEREOF
UNLESS A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.

                   INCREASE IN THE AGGREGATE NUMBER OF SHARES
      FOR WHICH STOCK OR STOCK OPTIONS MAY BE GRANTED UNDER THE COMPANY'S
               2000 EMPLOYEE, DIRECTOR AND CONSULTANT STOCK PLAN

                                (Notice Item 2)

General

   The Company's Board of Directors and stockholders approved the 2000
Employee, Director and Consultant Stock Plan (the "2000 Plan") in 2000. A total
of 1,500,000 shares of Common Stock were initially reserved for issuance under
the 2000 Plan. The 2000 Plan may be amended by the Board of Directors or the
Compensation Committee of the Board of Directors, provided that any amendment
approved by the Board of Directors or the Compensation Committee which is of a
scope that requires Stockholder approval in order to ensure favorable federal
income tax treatment for any incentive stock options under Code Section 422, is
subject to obtaining such stockholder approval. The Board of Directors has
voted to approve an amendment to the 2000 Plan to increase the aggregate number
of shares of Common Stock for which stock or stock options may be granted under
the 2000 Plan by 3,000,000 shares. This amendment is being submitted for
stockholder approval at the Meeting to ensure continued qualification of the
2000 Plan under ISO rules and 162(m) rules. The Board of Directors believes
that the increase is advisable to give the Company the flexibility needed to
attract, retain and motivate employees, Directors and consultants. All
employees and consultants of the Company and the members of the Board of
Directors are eligible to participate in the 2000 Plan.

Material Features of the 2000 Plan

   The purpose of the 2000 Plan is to attract, retain and motivate employees,
Directors and consultants through the issuance of stock options and/or stock
grants (together, the "Grants"), and to encourage ownership of shares of Common
Stock by employees, Directors and consultants of the Company. The 2000 Plan is
administered by the Compensation Committee. Subject to the provisions of the
2000 Plan, the Compensation Committee determines the persons to whom Grants
will be granted, the number of shares to be covered by each Grant and the terms
and conditions upon which a Grant may be granted, and has the authority to
administer the provisions of the 2000 Plan. All employees, Directors and
consultants of the Company and its affiliates (approximately 375 people) are
eligible to participate in the 2000 Plan.

   Options granted under the 2000 Plan may be either (i) options intended to
qualify as "incentive stock options" under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code"), or (ii) non-qualified stock options.
Incentive stock options may be granted under the 2000 Plan to employees of the
Company and its affiliates. Non-qualified stock options may be granted to
consultants, Directors and employees of the Company and its affiliates. The
Board has the discretion under the 2000 Plan to grant options to purchase the
Company's Company Stock to each non-employee Director, which options typically
vest monthly over either a three-year period or a four-year period, at an
exercise price equal to the fair market value of the Common Stock on such grant
date.

   The aggregate fair market value (determined at the time of grant) of shares
issuable pursuant to incentive stock options which become exercisable in any
calendar year under any incentive stock option plan of the Company may not
exceed $100,000. Incentive stock options granted under the 2000 Plan may not be
granted at a price less than the fair market value of the Common Stock on the
date of grant, or 110% of fair market value in the case of options granted to
an employee holding 10% or more of the voting stock of the Company. Non-
qualified stock options granted under the 2000 Plan may not be granted at an
exercise price less than 50% of the fair market value of the Common Stock on
the date of grant. Incentive stock options granted under the 2000 Plan expire
not more than ten years from the date of grant, or not more than five years
from the date of grant in the case of incentive stock options granted to an
employee holding 10% or more of the voting stock of the Company. An option
granted under the 2000 Plan is exercisable, during the optionholder's lifetime,
only by the optionholder and is not transferable by him or her except by will
or by the laws of descent and distribution.

                                       20


   A stock grant (or any part or installment thereof) and the purchase price
thereof, if any, shall be made (a) in United States dollars in cash or by
check, or (b) at the discretion of the Administrator (as defined in the 2000
Plan), through delivery of shares of Common Stock having a fair market value
equal as of the date of acceptance of the Stock Grant to the purchase price of
the Stock Grant determined in good faith by the Administrator, or (c) at the
discretion of the Administrator, by delivery of the grantee's personal recourse
note bearing interest payable not less than annually at no less than 100% of
the applicable Federal rate, as defined in Section 1274(d) of the Code, or (d)
at the discretion of the Administrator, by any combination of (a), (b) and (c)
above.

   An incentive stock option granted under the 2000 Plan may, at the
Compensation Committee's discretion, be exercised after the termination of the
optionholder's employment with the Company (other than by reason of death,
disability or termination for cause as defined in the 2000 Plan) to the extent
exercisable on the date of such termination, at any time prior to the earlier
of the option's specified expiration date or three months after such
termination. In granting any non-qualified stock option or stock grant, the
Compensation Committee may specify that such non-qualified stock option or
stock grant shall be subject to such termination or cancellation provisions as
the Compensation Committee shall determine. In the event of the optionholder's
death or disability, both incentive stock options and non-qualified stock
options generally may be exercised, to the extent exercisable on the date of
death or disability (plus a pro rata portion of the option if the option vests
periodically), by the optionholder or the optionholder's survivors at any time
prior to the earlier of the option's specified expiration date or twelve months
from the date of the optionholder's death or disability. Generally, in the
event of the optionholder's termination for cause, all outstanding and
unexercised options shall be forfeited. In the event of the death or disability
of an employee who has received a stock grant, generally the stock grant may be
purchased, to the extent exercisable on the date of death or disability (plus a
pro rata portion of the stock grant if the grant vests periodically), by the
holder or the holder's survivors at any time prior to the earlier of the stock
grant's specified expiration date or twelve months from the date of the
holder's death or disability. Generally, in the event of the holder's
termination for cause, all outstanding shares subject to the stock grant shall
be repurchased by the Company.

   If the shares of Common Stock shall be subdivided or combined into a greater
or smaller number of shares or if the Company shall issue any shares of Common
Stock as a stock dividend on its outstanding Common Stock, the number of shares
of Common Stock deliverable upon the exercise of an option issued or purchase
of a stock grant under the 2000 Plan shall be appropriately increased or
decreased proportionately, and appropriate adjustments shall be made in the
purchase price per share to reflect such subdivision, combination or stock
dividend. If the Company is to be consolidated with or acquired by another
entity in a merger, sale of all or substantially all of the Company's assets or
otherwise (an "Acquisition"), the Compensation Committee or the Board of
Directors of any entity assuming the obligations of the Company under the 2000
Plan, shall, as to outstanding Grants under the 2000 Plan either (i) make
appropriate provision for the continuation of such Grant by substituting on an
equitable basis for the shares then subject to such options or stock the
consideration payable with respect to the outstanding shares of Common Stock in
connection with the Acquisition or securities of the successor or acquiring
entity; or (ii) upon written notice to the participants, provide that all stock
grants must be purchased and all options must be exercised (either to the
extent then exercisable or, at the discretion of the Compensation Committee,
all options or grants being made fully exercisable for purposes of such
transaction) within a specified number of days of the date of such notice, at
the end of which period the Grants shall terminate; or (iii) terminate all
Grants in exchange for a cash payment equal to the excess of the fair market
value of the shares subject to each such option (either to the extent then
exercisable or, at the discretion of the Compensation Committee, all options
being made fully exercisable for purposes of such transaction) over the
exercise price thereof. In the event of a recapitalization or reorganization of
the Company (other than an Acquisition) pursuant to which securities of the
Company or of another corporation are issued with respect to the outstanding
shares of Common Stock, an optionholder upon exercising an option or a holder
upon payment for a stock grant under the 2000 Plan, shall be entitled to
receive for the purchase price paid upon such exercise the securities he or she
would have received if he or she had exercised such option or paid for such
stock prior to such recapitalization or reorganization.

                                       21


   The 2000 Plan may be amended by the stockholders of the Company. The 2000
Plan may also be amended by the Board of Directors or the Compensation
Committee, provided that any amendment approved by the Board of Directors or
the Compensation Committee which is of a scope that requires Stockholder
approval in order to ensure favorable federal income tax treatment for any
incentive stock options under Code Section 422, is subject to obtaining such
stockholder approval.

   As of February 15, 2001, an aggregate of 1,100,372 shares had been issued
upon the exercise of options or were issuable upon the exercise of options
outstanding under the 2000 Plan. On February 15, 2001, the closing market price
per share of the Company's Common Stock was $9.31, as reported in the NASDAQ
National Market System.

Federal Income Tax Considerations

   The following is a description of certain U.S. federal income tax
consequences of the issuance and exercise of options under the 2000 Plan:

   Incentive Stock Options. An optionee is generally not taxed on the grant or
exercise of an incentive stock option. The difference between the exercise
price and the fair market value of the shares on the exercise date will,
however, be a preference item for purposes of the alternative minimum tax. If
an optionee holds the shares acquired upon the exercise of an incentive stock
option final for at least two years following grant and at least one year
following exercise, the optionee's gain, if any, upon a subsequent disposition
of such shares is a capital gain (or loss). The measure of the gain is the
difference between the proceeds received on disposition and the optionee's
basis in the shares (which generally equals the exercise price). If an optionee
disposes of stock acquired pursuant to exercise of an incentive stock option
before satisfying the one and two-year holding periods described above, the
optionee will recognize both ordinary income and capital gain (or loss) in the
year of disposition. The amount of the ordinary income will be lesser of (i)
the amount realized on disposition less than optionee's adjusted basis in the
stock (usually the option price) or (ii) the difference between the fair market
value of the stock on the exercise date and the option price. The balance of
the consideration received on such a disposition will be capital gain if the
stock had been held for at least one year following exercise of the incentive
stock option. The Company is not entitled to an income tax deduction on the
grant or exercise of an incentive stock option or on the optionee's disposition
of the shares after satisfying the holding period requirement described above.
If the holding periods are not satisfied, the Company will be entitled to a
deduction in the year the optionee disposes of the shares, in an amount equal
to the ordinary income recognized by the optionee.

   Non-Qualified Stock Options. The grant of a non-qualified option will not
result in taxable income to the optionee or deduction to the Company at the
time of grant. The optionee will recognize taxable compensation, and the
Company will have a corresponding deduction, at the time of exercise in the
amount of the excess of the then fair market value of the shares acquired over
the option price. Upon disposition of the shares, the optionee will generally
realize capital gain or loss, and his basis for determining gain or loss will
be the sum of the option price paid for the shares plus the amount of
compensation income recognized on exercise of the option.

   The affirmative vote of a majority of the votes cast affirmatively or
negatively at the Meeting is required to approve the increase in the aggregate
number of shares of Common Stock available under the 2000 Plan.

   THE BOARD OF DIRECTORS RECOMMENDS APPROVAL OF THE ADOPTION OF AN AMENDMENT
TO THE 2000 PLAN TO INCREASE BY 3,000,000 SHARES THE AGGREGATE NUMBER OF SHARES
FOR WHICH STOCK OR STOCK OPTIONS MAY BE GRANTED UNDER THE 2000 PLAN, AND
PROXIES SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR OF SUCH AMENDMENT UNLESS
A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.

                                       22


  AMENDMENT OF THE COMPANY'S RESTATED CERTIFICATE OF INCORPORATION TO INCREASE
 FROM 50,000,000 SHARES TO 100,000,000 SHARES THE AGGREGATE NUMBER OF SHARES OF
              COMMON STOCK AUTHORIZED TO BE ISSUED BY THE COMPANY

                                (Notice Item 3)

   The Board of Directors has determined that it is advisable to increase the
Company's authorized Common Stock from 50,000,000 shares to 100,000,000 shares,
and has voted to recommend that the stockholders adopt an amendment to the
Company's Restated Certificate of Incorporation effecting the proposed
increase. The full text of the proposed amendment to the Restated Certificate
of Incorporation is attached to this Proxy Statement as Appendix B.

   As of February 15, 2001, approximately 33,443,293 shares of Common Stock
were issued and outstanding (excluding treasury shares) and approximately an
additional 6,160,138 shares were reserved for issuance upon the conversion of
existing securities and exercise of options granted under the Company's various
stock-based plans. Accordingly, a total of approximately 10,417,486 shares of
Common Stock are available for future issuance.

   The Board of Directors believes it continues to be in the best interest of
the Company to have sufficient additional authorized but unissued shares of
Common Stock available for issuance in order to provide flexibility for
corporate action in the future, including possible acquisitions of other
companies, financings, or other corporate purposes, as the Board of Directors
deems necessary to sustain and grow the Company. This increase will avoid
repeated separate amendments to the Company's Restated Certificate of
Incorporation and the delay and expense that would be incurred in holding
special meetings of Stockholders to approve such amendments. There are at
present no specific understandings, arrangements or agreements with respect to
any future acquisitions that would require the Company to issue a material
amount of new shares of its Common Stock. The Board of Directors believes that
the currently available unissued shares do not provide sufficient flexibility
for corporate action in the future.

   No further authorization by vote of the stockholders will be solicited for
the issuance of the additional shares of Common Stock proposed to be
authorized, except as might be required by law, regulatory authorities or rules
of the Nasdaq or any other stock exchange on which the Company's shares may
then be listed. The issuance of additional shares of Common Stock could have
the effect of diluting existing stockholder earnings per share, book value per
share and voting power. The stockholders of the Company do not have any
preemptive right to purchase or subscribe for any part of any new or additional
issuance of the Company's securities.

   The affirmative vote of a majority of the outstanding shares of the
Company's Common Stock is required to approve the amendment to the Company's
Restated Certificate of Incorporation to effect the proposed increase in the
Company's authorized shares.

   THE BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE THE AMENDMENT TO THE
COMPANY'S RESTATED CERTIFICATE OF INCORPORATION, AND PROXIES SOLICITED BY THE
BOARD WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS INDICATED
OTHERWISE ON THE PROXY.

                         INDEPENDENT PUBLIC ACCOUNTANTS

                                (Notice Item 4)

   The Board of Directors has appointed KPMG LLP, independent public
accountants, to audit the financial statements of the Company for the fiscal
year ending December 31, 2001. The Board proposes that the stockholders ratify
this appointment. KPMG LLP audited the Company's financial statements for the
fiscal year ended December 31, 2000. The Company expects that representatives
of KPMG LLP will be present at the Meeting, with the opportunity to make a
statement if they so desire, and will be available to respond to appropriate
questions.

Audit Fees

   The Company paid KPMG LLP a total of $450,000 for their audit of the
Company's annual financial statements for the fiscal year ended December 31,
2000 and for their review of the Company's Quarterly Reports on Form 10-Q filed
during the last fiscal year.

Financial Information Systems Design and Implementation Fees

   During the Company's fiscal year ended December 31, 2000, the Company paid
no fees to KPMG LLP for the provision of information technology services.

All Other Fees

   During the Company's fiscal year ended December 31, 2000, the Company paid
KPMG LLP a total of $1,076,000 for their provision of other services including
the review of SEC registration statements, issuance of comfort letters and
consents, acquisition due diligence assistance, consultation regarding the
effect of various accounting transactions, financial integration consulting
services and tax consultation and compliance.

   The Audit Committee has considered whether the provision of the services
described above under the caption(s) Financial Information Systems Design and
Implementation Fees and All Other Fees is compatible with maintaining KPMG's
independence.

   In the event that ratification of the appointment of KPMG LLP as the
independent public accountants for the Company is not obtained at the Meeting,
the Board of Directors will reconsider its appointment.

   The affirmative vote of a majority of the shares of Common Stock voted
affirmatively or negatively at the Meeting is required to ratify the
appointment of the independent public accountants.

   THE BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE THE RATIFICATION OF THE
APPOINTMENT OF KPMG LLP AS INDEPENDENT PUBLIC ACCOUNTANTS, AND PROXIES
SOLICITED BY THE BOARD WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS
INDICATED OTHERWISE ON THE PROXY.

                                 OTHER MATTERS

   The Board of Directors knows of no other business which will be presented to
the Meeting. If any other business is properly brought before the Meeting, it
is intended that proxies in the enclosed form will be voted in respect thereof
in accordance with the judgment of the persons voting the proxies.

                             STOCKHOLDER PROPOSALS

   To be properly brought before the Company's annual meeting of stockholders
to be held in 2002, stockholder proposals must be delivered to the Secretary of
the Company no earlier than March 15, 2002 nor later than the close of business
on April 15, 2002, unless the annual meeting to be held in 2002 is more than 30
days before or more than 60 days after such dates, in which case such
stockholder proposals must be delivered to the Secretary of the Company no
earlier than 90 days prior to and no later than 60 days prior to such annual
meeting or the close of business on the tenth (10th) day following the day on
which the Company publicly announces such annual meeting. Proposals received
after that date will not be voted on at the annual meeting. If a proposal is
received before that date, the proxies that management solicits for the meeting
may still exercise discretionary voting authority on the proposal under
circumstances consistent with the proxy rules of the Securities and Exchange
Commission. All stockholder proposals should be marked for the attention of
Donald R. Marvin, Senior Vice President, CFO and COO, Orchid BioSciences, Inc.,

II. AUDIT COMMITTEE COMPOSITION AND MEETINGS

   Audit Committee members shall meet the requirements of the National
Association of Securities Dealers (the "NASD"). Unless otherwise permitted by
the requirements of the NASD, the Audit Committee shall be comprised of three
or more Directors as determined by the Board, each of whom shall be independent
non-executive Directors, and free from any relationship that, in the opinion of
the Board, would interfere with the exercise of his or her independent judgment
as a member of the Audit Committee. All members of the Audit Committee shall
have a basic understanding of finance and accounting and be able to read and
understand fundamental financial statements, and at least one member of the
Audit Committee shall have past employment experience or expertise in finance
or accounting or other comparable experience or background which has resulted
in such member's financial sophistication.

   The members of the Audit Committee shall be elected by the Board at the
annual organizational meeting of the Board or until successors shall be duly
elected and qualified. If an Audit Committee Chairperson has not been elected
by the full Board, the members of the Audit Committee may designate a
Chairperson by majority vote of the Audit Committee membership.

   The Audit Committee shall meet at least four times annually, or more
frequently as circumstances dictate. The Audit Committee Chair shall prepare
and/or approve an agenda in advance of each meeting. The Audit Committee should

III. AUDIT COMMITTEE RESPONSIBILITIES AND DUTIES

   To fulfill its responsibilities and duties the Audit Committee shall:

    the Audit Committee Charter published at least every three years in
    accordance with SEC regulations (i.e. as an appendix to the proxy
    statement).

                                      A-1

6.  Oversee independence of the auditors by:

  .  receiving from the auditors, on a periodic basis, a formal written
     statement delineating all relationships between the auditors and the
     Company consistent with Independence Standards Board Standard 1 ("ISB
     No. 1");

  .  reviewing, and actively discussing with the Board, if necessary, and the
     auditors, on a periodic basis, any disclosed relationships or services
     between the auditors and the Company or any other disclosed
     relationships or services that may impact the objectivity and
     independence of the auditors; and

  .  recommending, if necessary, that the Board take certain action to
     satisfy itself of the auditors' independence.

General Responsibilities

7.  Prepare or assist in the preparation of an annual report to shareholders as
    required by the Securities and Exchange Commission. The report should be
    included in the Company's annual proxy statement.

8.  Perform any other activities consistent with this Charter, the Company's
    bylaws, and governing law, as the Audit Committee or the Board deems
    necessary or appropriate.

9.  Maintain minutes of meetings and periodically report to the Board on
    significant results of the foregoing activities.

10.  Report through its Chairperson to the Board following meetings of the
     Audit Committee.

IV. OTHER ACTIVITIES OF THE AUDIT COMMITTEE

   To the extent necessary to fulfill its responsibilities and duties described
in Articles I and II above, the Audit Committee may:

1.  Approve the fees and other significant compensation to be paid to the
    independent auditors.

                                      A-2


2.  Review the independent audit plan--discuss scope, staffing, locations,
    reliance upon management, and internal audit and general audit approach.

    appropriateness of the Company's accounting principles as applied in its

    auditors, the integrity of the Company's financial reporting processes,
    both internal and external.

9.  Consider and approve, if appropriate, major changes to the Company's
    auditing and accounting principles and practices as suggested by the
    independent auditors, management, or the internal auditing department.

10.  Establish regular systems of reporting to the Audit Committee by each of
     management, the independent auditors and the internal auditors regarding
     any significant judgments made in management's preparation of the
     financial statements and any significant difficulties encountered during
     the course of the review or audit, including any restrictions on the scope
     of work or access to required information.

11.  Review any significant disagreement among management and the independent
     auditors or the internal auditing department in connection with the
     preparation of the financial statements.
