                                PROXY STATEMENT

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

                              GENERAL INFORMATION


         We have sent this Proxy Statement to you in connection with the
solicitation of proxies for the annual meeting of our stockholders. The meeting
will be held at 9:00 a.m. Pacific Daylight Time on Tuesday, May 23, 2000.

         Record Date: The record date for the meeting is the close of business
on March 31, 2000. All holders of record on March 31, 2000, of our common stock
will be entitled to vote at the meeting. On the record date, there were
13,246,873 shares of common stock outstanding.

         Mailing Date: The date of this Proxy Statement is April 10, 2000. This
Proxy Statement and the proxy card will be mailed on or about April 12, 2000.

         Returning Your Proxy: Even if you do not attend the meeting you may
still vote your shares at the meeting by signing and returning your proxy card.
If you specify a choice on your proxy card, your shares will be voted according
to your choice. If you sign and return your proxy card but do not mark any
choices, then your shares will be voted:

         (1)   FOR election of the two Class I directors;

         (2)   FOR approval of an amendment to our Amended and Restated
               Articles of Incorporation, as amended, increasing the number of
               authorized shares of common stock from 50,000,000 to
               100,000,000;

         (3)   FOR approval of an amendment to the Hyseq, Inc. Non-Employee
               Director Stock Option Plan that (i) changes the method for
               determining the number of shares of our common stock covered by
               options that are granted under the Plan; and (ii) lengthens the
               vesting date for a new director's initial and first annual
               grants of options; and

         (4)   FOR approval of the amendment to our Employee Stock Purchase
               Plan increasing the number of shares of common stock available
               for issuance under the Plan from 50,000 to 250,000.

         Your signed proxy also gives the persons named on the proxy card,
called the proxies, the authority to vote your shares in the event that other
matters are properly brought before the meeting.



                                       2
<PAGE>   5


         Revoking Your Proxy: Even if you sign and return your proxy card, you
can always revoke it. You can terminate the original proxy you sent to us by
delivering a written notice of revocation or sending a subsequent signed proxy
card, so long as the revocation or subsequent signed proxy is received by us
before the meeting. If you sign and return your proxy card but then attend the
meeting, you can revoke your proxy by voting in person at the meeting.

         Quorum: A majority of the outstanding shares of common stock,
represented in person or by proxy, constitutes a quorum. A quorum is the number
of represented shares of stock needed to have a valid meeting to transact
business.

         Voting: Approval of the proposed amendment to our Amended and Restated
Articles of Incorporation, as amended that increases the number of authorized
shares of our common stock from 50,000,000 to 100,000,000, requires a majority
vote of all outstanding shares of our common stock. A majority vote of a quorum
is needed to approve each of the other proposals described in this Proxy
Statement. Shares of our common stock represented by valid proxies, i.e.,
executed proxies that are received in time for the meeting and are not later
revoked, will be voted at the meeting.

         We will tabulate the vote as follows:

         (1)   abstentions are treated as votes against a proposal;

         (2)   executed proxies are voted as indicated;

         (3)   executed proxies with no preferences are treated as votes for a
               proposal; and

         (4)   broker non-votes are treated as votes against the proposal to
               increase the number of authorized shares of common stock, but
               have no effect on the vote on the other proposals. A broker
               non-vote occurs when a broker lacks the authority to vote on
               some proposals, and so does not vote on those proposals.

         Cost of Solicitation: We bear the entire cost of holding the meeting,
including the solicitation of proxies. We ask banks, brokers and other
institutions, nominees and fiduciaries to forward the proxy materials to their
principals to obtain authority to execute proxies. We will reimburse them for
their expenses. In addition to the solicitation of proxies by mail, our
directors, officers or employees may solicit proxies in person or by telephone.

         Annual Reports: We are mailing our Annual Report to Stockholders for
the fiscal year 1999 along with this Proxy Statement. Our Annual Report to
Stockholders includes our financial statements for the year ended December 31,
1999. If you would like a copy of the Annual Report on Form 10-K for the fiscal
year ended December 31, 1999, that we filed with the Securities and Exchange
Commission, we will send you one without charge. Please send your request to:

          pursuant to stock options currently exercisable, or exercisable
          within 60 days after March 31, 2000, are deemed outstanding for

                                   MANAGEMENT
DIRECTORS

         Our Amended and Restated Articles of Incorporation, as amended, and
By-Laws, as amended, provide for our business to be under the direction of our
Board of Directors. Our Board is divided into three classes, with the members
of each class serving a staggered three-year term. Currently, our Board
comprises:

            o  three Class I directors: Mr. Weist and Mr. Gruber (and one
               vacancy);

            o  three Class II directors: Dr. Baddour, Ms. Marshall and Dr.
               Schweizer; and

            o  three Class III directors: Dr. Rathmann, Dr. Drmanac and Mr.
               McCarter.

         At each annual meeting of stockholders, the appropriate number of
directors will be elected for a three-year term to succeed the directors of the
same class whose terms are then expiring. Because the term of the Class I
directors expires in 2000, the Class I directors will be elected at this year's
meeting for a three year term expiring in 2003. The terms of the Class II
directors and the Class III directors expire in calendar years 2001 and 2002,
respectively. With the recent appointment of Dr. Rathmann as Chairman of the
Board, we have decided to defer appointment of a Class I director to fill the
vacancy in order that Dr. Rathmann may have time to discuss nominee
considerations with our Board. Your proxy cannot be voted for a greater number
of persons than the number of nominees named. Our Board met seven times in 1999.
No director attended less than 75% of the Board's meetings.

         The following table sets forth the names, ages and positions of our
directors as of March 31, 2000:

BOARD COMMITTEES

         Compensation Committee

         In April 1994, our Board established a Compensation Committee. The
Compensation Committee reviews, and makes recommendations to our Board, on our
compensation policies, practices and procedures designed to contribute to our
success. The Compensation Committee administers the 1995 Employee Stock Option
Plan (the "1995 Plan"), the Non-Employee Director Stock Option Plan and the
Scientific Advisory Board/Consultants Stock Option Plan. No member of the
Compensation Committee was at any time during the past three fiscal years an
officer or employee of ours or any of our subsidiaries. Mr. Weist, however,
served until February 2000 without compensation as the Chairman of our Board.
He did, however, receive fees as a director. As of February, 2000, Mr. Weist
serves as Vice Chairman of our Board, and as a director. He will continue to
serve as Vice Chairman without compensation. Dr. Baddour, as the Chairperson,
and Mr. Weist presently serve on the Compensation Committee, which met three
times during 1999.

         Audit Committee

         In March 1997, our Board established an Audit Committee. The Audit
Committee reviews our annual audit and meets with our independent auditors to
review our internal controls and financial management practices. Mr. McCarter,
as the Chairperson, and Dr. Baddour and Ms. Marshall presently serve on the
Audit Committee, which met five times during 1999.

         Nominating Committee

         In October 1996, we established a Nominating Committee. The Nominating
Committee considers and recommends individuals for Board membership and senior
management positions. The Nominating Committee will consider stockholders'
nominations for directors only if notice is received at our principal office in
Sunnyvale, California, at least 60 days, but not more than 90 days, prior to
the first anniversary of the preceding year's annual meeting of the
stockholders. Ms. Marshall, as the Chairperson, and Mr. Weist presently serve
on the Nominating Committee, which met two times during 1999.


DIRECTOR COMPENSATION

         During 1999, we paid all non-employee directors a fee of $2,500 for
each Board meeting attended in person or by telephone, subject to an overall
cap of $10,000 per year. Each non-employee director earned $10,000 in 1999.
During 1999, all non-employee directors also received fees of $1,000 for each
Committee meeting attended in person. Committee fees were not subject to the
$10,000 cap.




                                       8
<PAGE>   11
         On March 20, 2000, our Board increased the fee paid to our directors
who are not our employees to $6,250 per meeting attended in person or by
telephone, subject to a new overall cap of $25,000 per year. All non-employee
directors will continue to receive fees of $1,000 for each Committee meeting
attended in person and those fees will not be subject to the new $25,000 cap.
The Board also approved a new $6,000 fee per annum fee that will be paid to
Committee chairpersons who are not also our employees. All of the new fees will
become effective beginning with the meeting of our Board following this year's
meeting on May 23, 2000.

         Our employees who are also directors do not receive any Board or
Committee fees. All directors are reimbursed for reasonable expenses incurred
in attending Board and committee meetings.

         In October 1996, our stockholders approved the Non-Employee Director
Stock Option Plan. Under the Plan, each new non-employee director receives a
one-time grant of options to purchase 23,040 shares of common stock, of which
11,520 shares are exercisable immediately, with the balance becoming
exercisable in two equal allotments on the first and second anniversaries of
joining the Board. The Plan also provides that all non-employee directors
automatically receive options to purchase up to 5,760 shares each year (such
that the amount received under the Plan, when added to all other options
granted to a director which become exercisable in that year, totals 5,760) on
the date of each annual meeting of the stockholders. In accordance with the
Plan, Mr. Weist, Dr. Baddour and Ms. Marshall each received options to purchase
960 shares immediately following the annual meeting of the stockholders in
1999. A total of 138,240 shares of common stock are reserved for issuance under
the Plan. Options to purchase 93,120 of the original 138,240 reserved shares
have been issued as of December 31, 1999. All non-employee directors will
receive options to purchase 5,760 shares immediately following this year's
meeting if we do not amend the Plan as proposed. See "Item 3. Approval of
Amendment to Our Non-Employee Director Stock Option Plan" regarding proposed
changes to the Plan that would (i) change, for all directors who are not our
employees, the method for determining the number of shares issuable upon
exercise of initial and annual grants of options made on or after May 23, 2000;
and (ii) delay, for directors who become non-employee directors on or after May
23, 2000, the vesting dates for initial option grants and the first annual
grants made to such new directors. If approved by the stockholders, the
amendment would apply to all options granted on and after this year's meeting
that will be held on May 23, 2000. Options granted before May 23, 2000 would not
be affected.

(1)  In December 1996, Mr. Gruber purchased 48,000 shares of our common stock
     at $1.56 per share and 144,000 shares at $2.90 per share using the
     proceeds of a loan from us in the amount of $492,000. In March 1997, Mr.
     Gruber purchased 179,712 shares at $6.51 per share using the proceeds of a
     loan from us in the amount of $1,170,000. These shares vested over a
     period of two years ending in March 1999. Each of Mr. Gruber's loans bears
     interest at a rate of 3% per annum. The value representing the difference
     between the applicable federal rates on the dates of the loans and the 3%
     interest rates charged on each of the loans, is included as "Other
     Compensation." Mr. Gruber repaid his loans in February 2000 by delivery of
     approximately 15,000 shares to us.

(2)  Pursuant to the terms of an employment agreement which was effective
     through July 31, 1998, Dr. Drmanac was entitled to annual bonuses of
     $13,680.

(3)  Mr. Gitter was promoted to Chief Financial Officer in March of 1999. He
     was our Director of Finance and Controller from the time he joined us in
     July 1998 until his promotion. Mr. Gitter received a one-time
     reimbursement for relocation expenses of $7,500.

(4)  Dr. Drmanac was promoted to Vice-President of SBH Biochemistry in January
     1999. She was our Director of SBH Biochemistry Development prior to her
     promotion. Pursuant to the terms of an employment agreement which was
     effective through July 31, 1998, Dr. Drmanac was entitled to annual
     bonuses of $9,120.


As Dr. George B. Rathmann did not join us as Chairman of the Board until
February 2000, compensation earned by Dr. Rathmann will be reported in next
year's Proxy Statement. As an inducement to joining us as an employee, Dr.
Rathmann received a one-time grant of options to purchase 1,000,000 shares of
our common stock at $31.688 per share, the closing price of our stock on the day
before he was appointed. One-third of these options vested on the date of grant
and an additional one-third will vest on each of the two anniversaries
thereafter. Dr. Rathmann is receiving grants of options to purchase 3,000 shares
of our common stock per month, at the fair market value on each date of grant,
in lieu of cash compensation for his services as our employee.

           REPORT OF COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

         The Compensation Committee of our Board of Directors comprises Dr.
Baddour, as Chairperson, and Mr. Weist. The Compensation Committee's
responsibilities include recommending to the Board the compensation for our
executive officers, grants of stock options to our employees, and administering
our stock option and employee stock purchase plans. The Compensation Committee
bases its decisions on our executive compensation philosophy, which seeks to
relate salaries, bonuses and stock option awards to our success in meeting
annual and long-term performance goals, to reward individual achievement and to
attract and retain qualified executives.

         We set our executive officers' salaries in the low to mid-range
compared to those with similar management positions in peer companies
consisting primarily of other genomics and biotechnology companies. The level
of salaries paid to our executive officers also takes into account our
technological achievements during the year, its success in entering into
significant technology agreements with collaborators, as well as an evaluation
of the individual performance and contribution of each executive to our
performance for the year. Particular emphasis is placed on the individual
officer's level of responsibility for and role in meeting our strategic,
technological and financial objectives. Because of our stage of development,
the Compensation Committee has not used either the profitability or the market
value of our stock as a significant factor in consideration for setting
executive officer salaries.

BONUSES

         We award bonuses for accomplishments achieved during the past year.
The Compensation Committee recommends to the Board the amount of the bonus,
with advice from our management. The Compensation Committee makes its
recommendations based upon an assessment of the individual's contributions
during the year, compared to (but not restricted to) a list of goals previously
approved by management and the Compensation Committee. The Compensation
Committee also considers general factors relating to us in recommending the
size of the bonus pool and adjusts bonuses based on those factors as well. In
determining bonuses for the fiscal year ended December 31, 1999, (which are
paid in April 2000 and considered as compensation for the year 2000) the
Compensation Committee will consider, among other accomplishments:

         o  the establishment of a 3.5 year, $60 million collaboration with
            American Cyanamid Company;

         o  commencement of preclinical studies with our IL-Hy1 and CD39L4
            product candidates;

         o  identification of over 35,000 genes that contain signal peptide
            segments, indicating that they are capable of producing secretory
            proteins, or have significant homology to the coding regions of
            known genes;

         o  complete sequencing of more than 5,000 genes; and

         o  filing of numerous patent applications on gene discoveries,
            apparatus and processes and the issuance of two new
            technology-based patents, including a patent covering methods for
            identifying a base in a nucleic acid sequence.


STOCK OPTIONS

         Stock options awards are intended to align the interests of executives
with the interests of the stockholders in our long-term performance. The
Compensation Committee developed guidelines for executive stock option awards,
in consultation with our management. The guidelines are based upon:




                                      14
<PAGE>   17

         o  analysis of long-term incentive awards based on each individual
            executive's position;

         o  responsibilities, performance and contribution to the achievement
            of our long-term goals; and

         o  competitive stock option data from other genomics and biotechnology
            companies.


In addition, the Compensation Committee reviews the equity position of all
executive officers on an annual basis and awards stock options to executive
officers periodically.

CHIEF EXECUTIVE OFFICER'S COMPENSATION

         The 1999 compensation of Lewis S. Gruber, our Chief Executive Officer
and President, took into account the above policies and specific milestones we
achieved during the prior year. The Compensation Committee believes that Mr.
Gruber's salary of $268,750 for 1999 (plus a bonus of $53,250 paid in April
1999 in recognition of accomplishments in 1998) was in the low to middle range
compared to CEOs in peer companies consisting primarily of other genomics and
biotechnology companies. Mr. Gruber also received options to purchase 37,870
shares in 1999.

      COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

         Section 16(a) of the Securities Exchange Act of 1934 requires our
directors and officers and persons who beneficially own more than 10% of our
common stock to file with the Securities and Exchange Commission initial
reports of beneficial ownership and reports of changes in beneficial ownership
of the common stock and other equity securities of ours. Officers, directors
and greater than 10% beneficial owners are required by Securities and Exchange
Commission regulation to furnish us with copies of all Section 16(a) forms they
file. Specific due dates for these reports have been established by the
Commission and we are required to disclose in this Proxy Statement any failure
to file by such due dates during fiscal 1999.

         To our knowledge, based solely on review of the copies of such reports
furnished to us and written representations that no other reports were required,
during the fiscal year ended December 31, 1999, all Section 16(a) filing
requirements applicable to our officers, directors and greater than 10%
beneficial owners were complied with except for a Form 5 which was to be filed
by Robert D. Weist by February 14, 2000. Mr. Weist's Form 5 will be filed on or
before April 10, 2000.

                              CERTAIN TRANSACTIONS

         In December 1993, Lewis S. Gruber, one of our directors and an
executive officer, received a warrant to purchase 144,000 shares of common
stock at $2.90 per share in exchange for the assignment of all right, title and
interest in and to certain patent rights relating to diagnostic applications
owned by him. In connection with our hiring of Mr. Gruber in June 1994, we
granted him a 10-year option to purchase 345,600 shares of common stock at an
exercise price of $1.56 per share. In December 1996, Mr. Gruber used the
proceeds of a loan from us to exercise the warrant to purchase 144,000 shares
of common stock at $2.90 per share and to exercise options to purchase 48,000
shares of common stock at an exercise price of $1.56 per share. The loan, in
the principal amount of $492,000, was evidenced by a promissory note dated
December 9, 1996, that bore interest at 3% per annum and was due on December 8,
2001. The loan was secured by, and with recourse only to, 118,080 shares of Mr.
Gruber's common stock. In March 1997, Mr. Gruber purchased 179,712 shares at
$6.51 per share using the proceeds of an additional $1,170,000 loan, as
evidenced by a promissory note dated March 12, 1997, on the same terms as his
prior loan. As a condition of the purchase, Mr. Gruber did not receive any
options under the 1995 Plan during 1997. In February 2000, Mr. Gruber repaid
both notes and accrued interest totaling $1,811,208. The notes were repaid by
surrendering to us approximately 15,000 shares of common stock.

         Mr. Gruber's spouse was one of our directors from our inception to
June 1994 and is a member of Sachnoff & Weaver, Ltd., a law firm which has
served as our general corporate counsel since June 1996. Sachnoff & Weaver,
Ltd. and certain members and related persons in addition to Mr. Gruber's spouse
are stockholders. In January 1997, Sachnoff & Weaver, Ltd. purchased 76,800
shares of common stock at $6.51 per share. Sachnoff & Weaver, Ltd. paid
$102,415 in cash and delivered a promissory note to us for the balance in the
amount of $397,585 secured by 61,069 shares of common stock. The note bore
interest at 8.25% per annum and was paid in full during 1998. We incurred legal
fees and costs to Sachnoff & Weaver, Ltd. of approximately $441,000 in 1999.

                  MATTERS TO BE CONSIDERED BY THE STOCKHOLDERS

ITEM 1.     ELECTION OF CLASS I DIRECTORS

         We have three classes of directors that serve staggered, three-year
terms. There are currently two Class I directors, three Class II directors and
three Class III directors. The Board of Directors has nominated the current
Class I directors, Mr. Robert D. Weist and Mr. Lewis S. Gruber, for
re-election. There are no other nominees for Class I director. Each Class I
director elected at the annual meeting will serve a three-year term ending on
the date of the annual meeting in 2003 or until a successor is duly elected or
appointed.

         You may vote for either or both of the nominees for Class I director,
or you may withhold your votes for either or both of them, by completing,
signing and returning the enclosed proxy card or by attending the meeting. IF
YOU SIGN AND RETURN THE PROXY CARD BUT NEGLECT TO COMPLETE THE "VOTE
FOR/WITHHOLD AUTHORITY" SECTION, THE PROXIES WILL VOTE YOUR SHARES FOR EACH OF
THE NOMINEES. Both of the nominees have agreed to serve as a director if
elected; however, if either nominee is unable or unwilling to accept nomination
or election, the proxies will then vote your shares for such other person or
persons as the Board recommends.

         Our By-Laws require the affirmative vote of a majority of the votes
cast by stockholders present, in person or by proxy, and eligible to vote at
the meeting, provided that a quorum exists, to elect directors.

         RECOMMENDATION OF THE BOARD OF DIRECTORS: The Board of Directors
recommends that you vote for both Mr. Weist and Mr. Gruber.

ITEM 2.     APPROVAL OF AMENDMENT TO OUR AMENDED AND RESTATED ARTICLES OF
            INCORPORATION TO INCREASE AUTHORIZED COMMON STOCK

         On February 1, 2000, our Board of Directors approved an amendment to
our Amended and Restated Articles of Incorporation, as amended, which increases
the number of authorized shares of common stock, $.001 par value per share, from
50,000,000 to 100,000,000, primarily in contemplation of as yet undetermined
future public and private offerings of our securities. Our Amended and Restated
Articles of Incorporation, as amended, currently authorize 50,000,000 shares of
common stock and 8,000,000 shares of preferred stock. Of the 50,000,000
authorized shares of common stock, approximately 13,246,873 were issued and
outstanding as of March 31, 2000. Approximately 3,982,338 additional shares are
reserved for issuance upon the exercise of warrants and options. No change is
proposed for the number of authorized shares of preferred stock.

         The proposed amendment will modify, as follows, the first paragraph of
Article Fourth of our Amended and Restated Articles of Incorporation, as
amended:

         "FOURTH: The number and classes and/or series of shares the Corporation
         is authorized to issue is as follows:

         Number of
        Authorized
          Shares                   Class or Series                  Par Value
        ----------                 ---------------                  ---------
          3,000,000         Preferred Stock Series A                $.001
          5,000,000         All Other Series Preferred Stock         .001
        100,000,000         Common Stock                             .001


         No other provisions of Article Fourth of the Amended and Restated
         Articles of Incorporation, as amended or of the Amended and Restated
         Articles of Incorporation, as amended are to be amended."

         You may vote for approval of the amendment, vote against approval, or
abstain from voting altogether by completing, signing and returning the
enclosed proxy card or by attending the meeting. IF YOU SIGN AND RETURN THE
PROXY CARD BUT NEGLECT TO COMPLETE THE "FOR/AGAINST/ABSTAIN" SECTION, THE
PROXIES WILL VOTE YOUR SHARES FOR APPROVAL OF THE AMENDMENT TO OUR AMENDED AND
RESTATED ARTICLES OF INCORPORATION.




                                      18
<PAGE>   21

         Approval of the amendment requires the affirmative vote of a majority
of the stockholders eligible to vote at the meeting, whether present at the
meeting or not.

         RECOMMENDATION OF THE BOARD OF DIRECTORS: The Board of Directors
recommends that you vote for approval of the amendment to our Amended and
Restated Articles of Incorporation as amended, which increases the number of
authorized shares of common stock from 50,000,000 to 100,000,000.

ITEM 3.     APPROVAL OF AMENDMENT TO OUR NON-EMPLOYEE DIRECTOR STOCK OPTION
            PLAN

         On March 20, 2000, our Board of Directors approved Amendment No. 3 to
our Non-Employee Director Stock Option Plan, as amended. If you approve
Amendment No. 3, it will apply to all grants of options under this Plan
beginning on May 23, 2000. The amendment will not effect any options granted
before May 23, 2000. Amendment No. 3 will change the number of shares issuable
upon exercise of initial and annual grants of options. The number of shares will
change from a fixed number to a number equal to the lesser of (i) 10,000 shares
or (ii) the number determined by dividing $200,000 by the fair market value of
our common stock on the date of grant. The amendment also will delay the vesting
date for the initial grant of an option to a new director so that 50% vests one
year after the grant date and the other 50% vests two years after the grant
date. Additionally, the first annual grant of options to a new director will
vest on the later of (i) the first anniversary of the date on which that
director joined the Board, or (ii) the date of grant, with subsequent grants of
annual options vesting on the date of grant as they do under the existing Plan.
All other provisions of this Plan will remain in full force and effect.
Presently, Mr. Weist, Dr. Baddour, Ms. Marshall, Mr. McCarter and Dr. Schweizer
qualify to participate in the Non-Employee Director Stock Option Plan.

         The following is a description of the material features of the
Non-Employee Director Stock Option Plan and Amendment No. 3. Amendment No. 3
requires your approval to be adopted.

OPERATION OF THE PLAN WITHOUT AMENDMENT NO. 3

         Under the current Non-Employee Director Stock Option Plan, directors
who are not employees automatically receive options to purchase 23,040 shares
upon their initial election to the Board. Options to purchase 11,520 of these
shares are exercisable immediately, with the balance becoming exercisable in two
equal allotments on the first and second anniversaries of joining our Board. All
non-employee directors also automatically receive options to purchase up to
5,760 shares each year (such that the amount received under the Plan, when added
to all prior options granted to a director that become exercisable in that year,
total 5,760) on the date of the annual meeting of the stockholders. These
options are exercisable immediately. All options are granted at the fair market
value of our common stock on the date of grant.

         At our 1998 annual meeting, the stockholders approved Amendment No. 1
and Amendment No. 2 to the Non-Employee Director Stock Option Plan. Amendment
No. 1 added alternative exercise price payment methods, removed certain
restrictions on the exercise of options after a director ceases to be a
director, and added a definition of the term "cause" as used in the Plan.
Amendment No. 2 added a provision that accelerates the vesting of options
granted under the Plan upon a change of control.

         Under the Non-Employee Director Stock Option Plan, a maximum of 138,240
shares of our common stock can be issued. As of March 31, 2000, options to
purchase 93,120 shares of common stock were issued and




                                      19
<PAGE>   22

outstanding under the Plan, leaving 45,120 shares available for future option
grants. The next automatic option grants under the Plan, or under proposed
Amendment No. 3 if approved, will be made at the close of business on May 23,
2000. Under the Plan and Amendment No. 3, the options will be granted at the
fair market value of our common stock on the date of grant.

OPERATION OF THE PLAN WITH AMENDMENT NO. 3

         If the Plan is amended as proposed, directors who are not our
employees will continue to receive an automatic initial grant of options when
they join our Board, and thereafter, receive annual grants at the close of
business on the day of our annual meetings of stockholders. However, under the
amended Plan, the number of shares that can be purchased upon exercise of the
options will be equal to the lesser of (i) the number determined by dividing
$200,000 by the fair market value of our common stock on the date of grant; or
(ii) 10,000 shares. Amendment No. 3 also will revise the vesting date for
initial options that are granted when a new director joins our Board. As
proposed, 50% of a new director's options will vest one year after the grant
date and the other 50% will vest two years after the grant date. Additionally, a
new director's first annual grant of options will vest on the first anniversary
of the date on which he or she joins our Board, or if later, the date of grant.
All other provisions of the Non-Employee Director Stock Option Plan will remain
in full force and effect.

REASONS FOR THE AMENDMENT

         We believe that our Non-Employee Director Stock Option Plan, as
operated under Amendment No. 3 allows us to ensure that our directors are fairly
rewarded for their services while providing us with an absolute measure
($200,000) of the initial value of the options we are granting them. Our Board
believes the proposed vesting change will provide more incentive for new
directors to take an active role in fulfilling their duties. There is currently
one Class I director vacancy, which, when filled, would automatically result in
a grant of options to purchase 23,040 shares under the existing Plan.
Additionally, our five current non-employee directors, will each be granted
options to purchase 5,760 shares per year, for a yearly aggregate of up to
28,800 shares under the existing Plan. By comparison, under Amendment No. 3, if
the fair market value for our shares on May 23, 2000 were $44.63 (the closing
price for our shares on the record date), options to purchase 4,481 shares would
issue to each director. The dollar value of options granted under Amendment No.
3 would be $200,000 per director whereas the dollar value of options granted
under the existing Plan would be $257,069 (5,760 multiplied by $44.63).

         Amendment No. 3 also limits grants of initial and annual options to a
maximum of 10,000 shares per grant to offset against any future fall in our
stock price. With this limit on initial and annual grants, the initial option
grant to a new director decreases under Amendment No. 3 from a fixed number of
23,040 shares to a maximum of 10,000 shares. Annual grants to all directors also
decrease to less than 5,760 shares per director under the Amendment No. 3
formula unless the price at which our shares trade decreases to less than $34.72
per share. A total of 45,120 shares remain available for issuance under the
Plan. The Board determined not to recommend an increase in the number of shares
authorized under the Plan this year based on the current fair market value of
our common stock.

         We believe that the inherent value created by granting options under
the Non-Employee Director Plan has and will continue to be a successful means
of attracting, retaining and motivating highly qualified individuals for our
Board of Directors.




                                      20
<PAGE>   23

         As of March 31, 2000, the market value of the 138,240 shares issued or
available for issuance under the Non-Employee Director Stock Option Plan was
$6,169,651. No options may be granted under the Plan after October 23, 2005.

MISCELLANEOUS PROVISIONS

         The Non-Employee Director Stock Option Plan is administered by the
Compensation Committee, which presently comprises Dr. Baddour and Mr. Weist.
The Compensation Committee has full authority to interpret and administer the
Plan, and to correct any defect or omission or reconcile any inconsistency in
the Plan, and its decisions are conclusive and binding upon us and all other
persons.

         If a participant ceases to be a director by reason of disability, the
participant's right to exercise any unexercised options granted under the
Non-Employee Director Stock Option Plan shall be subject to the condition that,
until those options are exercised, the participant (i) shall not be engaged as
an advisor, principal, agent, partner, officer, director or employee in any
business or activity which is competitive with our business, and (ii) shall be
reasonably available to us for consultation. If a participant fails to comply
with these conditions, he will forfeit all rights as to any unexercised
options.

         Although our Board of Directors may amend or terminate the
Non-Employee Director Stock Option Plan at any time, no amendment may, without
stockholder approval, materially increase the number of shares of common stock
issuable under the Plan, materially modify the requirements as to eligibility
for participation, materially increase the benefits accruing to participants
under the Plan or extend the termination date of the Plan. The Compensation
Committee may amend or modify any outstanding options in any manner consistent
with the Compensation Committee's authority under the Plan. No such amendment
or modification may impair the rights of a participant under the option without
that participant's consent.

FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of the United States federal income tax
consequences that generally will arise with respect to the grant and exercise
of awards under the Non-Employee Director Stock Option Plan and with respect to
the sale of common stock acquired under the Non-Employee Director Stock Option
Plan:

         Tax Consequences to a Participant. A participant will not recognize
ordinary income upon the grant of a non-statutory option. Upon exercise of a
non-statutory option, a participant generally will recognize ordinary income in
an amount equal to the difference between the exercise price for the option and
the fair market value of the common stock on the exercise date. With respect to
any common stock acquired upon the exercise of a non-statutory option, a
participant will have a tax basis equal to the exercise price plus any income
recognized upon the exercise of the option. Upon selling common stock acquired
upon the exercise of a non-statutory option, a participant generally will
recognize capital gain or loss in an amount equal to the excess of the sale
price of the common stock over the participant's tax basis in that common
stock. The capital gain or loss will be long-term, midterm or short-term gain
or loss, depending upon the holding period of the shares.

         Tax Consequences to Us. We generally will be entitled to a
business-expense deduction with respect to any ordinary compensation income
recognized by a participant, provided that we include and report those amounts
on a timely filed Form W-2 or Form 1099 - MISC (or similar IRS form filing).

Director Stock Option Plan.


ITEM 4.     APPROVAL OF AMENDMENT TO OUR EMPLOYEE STOCK PURCHASE PLAN

         On February 1, 2000, the Board of Directors adopted, subject to
stockholder approval, an amendment to our Employee Stock Purchase Plan, which
increases the aggregate number of shares of common stock available for purchase
under the Plan from 50,000 to 250,000. All other provisions of the Plan remain
in full force and effect. The following is a description of the material
features of the Plan:

GENERAL INFORMATION

         At our 1998 annual meeting, our stockholders approved the Employee
Stock Purchase Plan providing an opportunity for our eligible employees to
purchase common stock through payroll deductions. We believe that the Plan is
an effective means of aligning employees' interests, through their purchases of
common stock, with the interests of stockholders. The Plan is an integral part
of our over-all employee benefits package, which we rely on to help attract and
retain motivated and talented employee.

REASONS FOR THE AMENDMENT

         The Employee Stock Purchase Plan currently provides that the aggregate
number of shares of common stock available for purchase under the Plan is
50,000. However, 48,219 of those originally available shares of common stock
have already been purchased through the Plan, leaving only 1,781 shares
available for future purchases. The Plan has been so successful that the number
of shares available for purchase were depleted sooner than originally
anticipated. As the number of our employees grows, we expect the demand for
shares under the Plan to grow as well. Considering the growing number of
employees who are expected to participate in the Plan, we expect the shares
made available by the amendment, if approved by our stockholders, will meet our
needs until 2003. Because the Plan is a key benefit for employees and is part
of what we believe is a very competitive compensation package, which allows us
to attract and retain high-quality employees, we feel strongly that the Plan
should be amended so that there is a sufficient number of shares available for
future purchases.




                                      22
<PAGE>   25

DESCRIPTION OF THE EMPLOYEE STOCK PURCHASE PLAN

         The purpose of the Employee Stock Purchase Plan is to enable our
eligible employees and employees of our subsidiaries to acquire a proprietary
interest in us by purchasing common stock through payroll deductions. If the
amendment is approved, the total number of shares of our common stock that have
been purchased under the Plan, plus the number of shares that will be available
for purchase by employees upon the exercise of purchase rights granted under
the Plan, will equal 250,000. If any purchase right granted under the Plan
expires or terminates for any reason without having been exercised in full or
ceases for any reason to be exercisable in whole or in part, the unpurchased
shares subject to that grant will be added back to the number of shares
available for purchase. The aggregate maximum number of shares will be subject
to appropriate adjustment in the event of stock dividends, stock splits,
recapitalization, or similar changes affecting the outstanding shares of common
stock. As of March 31, 2000, the market value of the 250,000 shares issued or
available for issuance under the Plan was $11,157,500.

         The Plan is administered by our Compensation Committee, which
currently comprises Dr. Baddour and Mr. Weist. The Committee has full authority
to construe and interpret the Plan and correct any defect or omission or
reconcile any inconsistency in the Plan, and its decisions are final,
conclusive and binding upon all employees and all persons claiming under or
through any employee.

         All of our employees (except for those who already own 5% or more of
our common stock) and, if designated by our Board of Directors, the employees
of our subsidiaries, are eligible to participate in the Employee Stock Purchase
Plan on the first Offering Date coincident with or next following the
employee's completion of 90 days of continuous service. For purposes of the
Plan, an "Offering Date" is defined as the date on which the administering
committee grants an eligible employee the right to purchase shares of common
stock. An eligible employee may become a participant in the Plan effective the
first day of an offering period following the submission of an enrollment form
that authorizes deductions from the employee's paycheck, so long as the
enrollment form is submitted to the committee at least 15 days prior to the
first day of the applicable offering period. If an enrollment form is submitted
less than 15 days before the first day of an offering period, it shall become
effective on the first day of the next succeeding offering period. A
participant may elect to have deductions made from his or her pay on each
payday at a whole number percentage rate of at least 1% but less than 10% of
the compensation that he or she is entitled to receive. A participant may
increase the rate of his payroll deductions effective as of any subsequent
Offering Date by filing a new authorization form with the committee 15 or more
days before the next Offering Date. A request for a decrease in payroll
deductions becomes effective as soon as practicable after it is filed with the
Committee.

         The common stock to be sold under the Employee Stock Purchase Plan may
be shares acquired on the open market, treasury shares or shares newly issued
for the purpose. The purchase price for shares of common stock to be purchased
with payroll deductions is 85% (or such other amount as the committee
authorizes, but in no event less than 85%) of the fair market value of the
common stock on the date on which a grant of a purchase right under the Plan is
made or on the date on which the common stock is purchased, whichever is less.
The fair market value of the common stock on a given date shall be determined
by the committee based upon the reported closing sales price of the common
stock on the Nasdaq National Market on such date. If the limit on the number of
shares of common stock available to be purchased under the Plan is reached,
then the last purchase of common stock shall be allocated among the
participants pro rata based upon the number of shares that would have been
purchased under the Plan without this limitation.




                                      23
<PAGE>   26

         A participant may elect to withdraw his shares or any cash credited to
his account at any time. All of the cash deposits returned to the participant
will be paid to him promptly after receipt of the notice of the withdrawal,
without interest. Shares of common stock to be delivered to the participant
will be registered in his name, or if the participant directs in writing to the
committee, in the name of the participant and the person designated by the
participant, and will be delivered to the participant as soon as practicable
after the request for withdrawal. If the participant wishes to sell shares of
the common stock in his account, he may request that the Compensation Committee
sell the shares on his behalf, in which event all commission costs incurred in
connection with the sale of the shares of common stock will be paid by the
participant.

         If a participant terminates his employment or otherwise becomes
ineligible to participate in the Employee Stock Purchase Plan, any unused
payroll deductions will be returned to him without interest. A participant may
terminate payroll deductions at any time by giving written notice to the
committee. A participant must wait six months from the date his withdrawal from
the Plan before he may reenter the Plan. An employee must be employed by us or
one of our affiliates on the date that the common stock is purchased in order
to participate in the purchase for that offering period.

         An employee will not be granted a purchase right under the Employee
Stock Purchase Plan if he owns, immediately after the grant of the purchase
right, 5% or more of the voting power or value of all classes of our stock or
that of any of our affiliates, or if purchase rights under the Plan or any
other plans qualified under Section 423 of the Internal Revenue Code, would
result during any calendar year in the purchase of shares having an aggregate
fair market value of more than $25,000.

         Our Board of Directors may amend or terminate the Employee Stock
Purchase Plan at any time, provided that no amendment shall, without
stockholder approval, increase the number of shares of common stock available
for purchase under the Plan (except upon stock splits and dividends,
combinations and similar events), change the class of affiliates whose
employees are eligible to participate in the Plan, or otherwise effect a change
inconsistent with Code Section 423.

         You may vote for approval of the amendment, vote against approval, or
abstain from voting altogether by completing, signing and returning the
enclosed proxy card or by attending the meeting. IF YOU SIGN AND RETURN THE
PROXY CARD BUT NEGLECT TO COMPLETE THE "FOR/AGAINST/ABSTAIN" SECTION, THE
PROXIES WILL VOTE YOUR SHARES FOR APPROVAL OF THE AMENDMENT TO THE EMPLOYEE
STOCK PURCHASE PLAN.

         Approval of the amendment requires the affirmative vote of a majority
of the votes cast by the stockholders present, in person or by proxy, and
eligible to vote at the meeting, a quorum being present. A copy of the proposed
amendment is attached as Exhibit B and is incorporated into this proxy
statement by this reference.

RECOMMENDATION OF THE BOARD OF DIRECTORS: The Board of Directors recommends
that you vote for approval of the amendment to the Employee Stock Purchase
Plan, which increases the number of shares issuable under the Plan from 50,000
to 250,000.

         As of the date of this Proxy Statement, we do not know of any other
business to be considered at the meeting. However, if any additional matters
are properly presented at the meeting, the persons named in the proxy, or their
substitutes, will vote your shares in accordance with their judgment on such
matters.

                                STOCK OPTION PLAN

         WHEREAS, the Board of Directors and the Stockholders of Hyseq, Inc. has
approved that certain Amendment No. 3 to the Hyseq, Inc. Non-Employee Director
Stock Option Plan (the "Plan"), to become effective with respect to all Initial
and Subsequent Option grants made on or after May 23, 2000. All Initial Options
and Subsequent Options granted prior to the effective date of this Amendment No.
3 shall continue to be governed by the terms of the Plan as in existence prior
to the effective date of this Amendment No. 3.

         NOW, THEREFORE, the Plan is hereby amended as follows:

         1.       Article 2.1 shall be amended to read as follows:

                  Effective on the date on which a director first becomes a
         member of the Board of Directors of the Company, commencing with
         directors who first become members on or after May 23, 2000 ("New
         Directors"), each New Director who satisfies the conditions set forth

         3.2) equal to the lesser of (i) the number determined by dividing

         determined pursuant to Section 3.6(a) of the Plan) as of the date the
         Subsequent Option is granted, or (ii) 10,000; provided, however, that a
         director who is granted an Initial Option at an Annual Meeting of the
         Stockholders shall not be entitled to receive his or her first
         Subsequent Option until the next Annual Meeting of the Stockholders.
         (Collectively, the Subsequent Option(s) and the Initial Option(s) may
         be referred to herein as an "Option" or "Options".)

                  c. With respect to Initial Options granted prior to May 23,
         2000, one half of the Participant's Initial Option shall be exercisable
         on the date of grant and one fourth of the Initial Option shall become
         exercisable on the date of the Annual Meeting of the Stockholders held

         after May 23, 2000, the Participant's Initial Option shall be
         exercisable as follows: Fifty percent (50%) of the Initial Option shall
         be exercisable on the first anniversary of the date of grant and the
         remaining fifty percent (50%) of the Initial Option shall become
         exercisable on the second anniversary of the date of grant. All Initial
         Options shall be exercisable until the tenth anniversary of the date of
         grant. Each director's first Subsequent Option shall vest on the later
         of (i) the first anniversary of the date on which the New Director
         becomes a member of the Company's Board of Directors, or (ii) the grant
         date of the Subsequent Option. All other Subsequent Options shall
         become exercisable on the date of grant (the date of each Annual
         Meeting.) Subsequent Options shall be exercisable until the tenth
         anniversary of the date on which the Subsequent Option(s) was granted.
         The foregoing notwithstanding, (i) in the event a Participant's status
         as a non-employee director ceases as the result of his termination for
         cause, all of the Participant's outstanding Options shall immediately
         terminate and (ii) upon the date the Participant ceases to serve as a
         non employee director of the Company for any reason or for no reason,
         all vesting of Options under this Plan shall cease.
