statement or representation except those expressly stated in this Agreement or

directly or indirectly, whether superficially or substantively, conflicts with
any term or condition contained in the attached Addendum, the term(s) and/or
condition(s) of the Addendum shall control in their entirety, and the
conflicting term(s) and/or condition(s) of this Agreement shall be completely
null and void, and of no further effect.

remedy in respect of any occurrence or event on one occasion shall not be deemed

between Hyseq, Inc., a Nevada corporation ("Company" or "Hyseq"), with its
principal place of business at 670 Almanor Avenue, Sunnyvale, California, 94085,
and Dr. Ted W. Love ("Executive") is effective as of the date of the Agreement
("Effective Date").

                                   EMPLOYMENT

     1.1  Position and Duties: The Company employs Executive and Executive
accepts employment according to the terms and conditions set forth in the
Agreement and this Addendum.

          (a)  Executive shall serve as President and Chief Operating Officer
               ("COO") of Hyseq from the Effective Date until the date Hyseq
               promotes Executive to Chief Executive Officer ("CEO") and
               President of the Company. Executive shall have all the rights,
               responsibilities, authority, and titles commensurate with the
               position of President and COO. As long as Executive serves as
               President and COO, Executive shall report only to the CEO, Dr.
               George B. Rathmann, and the Company's Board of Directors
               ("Board").

          (b)  In his position as President and COO, Executive shall be
               responsible for all aspects of the Company's operations and all
               functional areas of the Company.

          (c)  Hyseq shall (x) promote Executive to President and CEO of the
               Company on or before July 1, 2002 (the "Promotion Date"), or (y)
               pay Executive four million dollars ($4,000,000), less the Stock
               Appreciation (as defined below), in one lump sum, on the
               Promotion Date or on any other applicable date as set forth in
               Section 3.2(b) or the date on which Executive's employment
               terminates before the Promotion Date other than for Cause (as
               defined below) or Good Reason (as defined below) exists (the
               applicable payment date is referred to in this Addendum as the
               "NonPromotion Date"); providing that if Company had Cause (as
               defined below) not to promote Executive to CEO, then Company
               shall not pay Executive the payment called for in this Section.

          (d)  Hyseq understands and acknowledges that Company's representation
               that it will pay Executive four million dollars, less the Stock
               Appreciation, if Company chooses not to promote Executive (unless
               Cause exists not to promote Executive) is a material
               representation inducing Executive to enter into the

               Agreement and this Addendum, and that Executive will not accept
               employment with the Company without this representation.
               Executive represents that, in reliance on the Company's
               representation, he has given up multiple opportunities to become
               Chief Executive Officer of other biotechnology companies.

          (e)  In addition, if the Company is required to pay Executive $4
               million less the Stock Appreciation pursuant to Sections 1.1(c)
               or 3.2(b), then during the period of time beginning on the
               NonPromotion Date and ending sixty (60) days after the
               NonPromotion Date, Executive, at his sole discretion, may sell
               all or any portion of his vested Option Shares (whether exercised
               or unexercised) ("Forced Sale Shares") to Hyseq and Hyseq shall
               be immediately required to purchase all Forced Sale Shares at the
               fair market value as of date Executive elects such sale (but in
               the case of vested but unexercised Shares, the fair market value
               less the exercise price).

          (f)  The Executive shall be appointed to the vacancy currently
               existing on the Company's Board of Directors ("Board") and
               thereafter, at all times while Executive is employed by the
               Company, the Company shall nominate to the Board and recommend to
               the shareholders that the shareholders elect Executive to the
               Company's Board.

          (g)  For purposes of this Addendum, "Stock Appreciation" means an
               amount equal to (x) the number of Executive's vested option
               Shares in excess of 150,000 Shares (regardless of whether such
               Shares have been exercised or forfeited) on the NonPromotion Date
               multiplied by (y) the amount resulting from taking (i) the
               closing price of Hyseq's common stock on the NASDAQ Stock Market
               on the NonPromotion Date and subtracting (ii) the exercise price
               of the vested option Shares.

     1.2  Best Efforts. Executive agrees to devote his full time and attention
to the Company, to use his best efforts to advance the business and welfare of
the Company, to render his services under the Agreement and this Addendum fully,
faithfully, diligently, competently and to the best of his ability.

not materially interfere with the proper performance of his duties and
responsibilities under the Agreement and this Addendum:

               affairs.

          (e)  Executive may participate in conferences, prepare or publish
               papers or books or teach; and,

          (f)  Executive may take on other positions of responsibility, with the
               approval of the Board, which approval shall not be unreasonably
               withheld.

     1.3  Location of Employment. Executive's principal place of employment
shall be at a location that is within thirty (30) miles of the Company's current
headquarters, unless the relocation of Executive's principal place of employment
by more than thirty (30) miles results in moving Executive's principal place of
employment closer to the Executive's current residence in Hillsborough,
California.

     1.4  Authorization to Work in the United States. The Immigration Reform and
Control Act of 1986 requires that Executive provide verification of identity and
legal right to work in the United States. Consequently, within three days of
beginning his employment with the Company, Executive must provide the Company
with proper documentation as required by the Employment Eligibility Verification
Form I-9.

                            COMPENSATION AND BENEFITS

     2.1  Base Salary. For services rendered by Executive under the Agreement
and this Addendum, the Company shall pay Executive a base salary of $485,000 per
year, less deductions required by law, payable in equal bi-monthly installments.
The Board shall review annually Executive's compensation, and the Board shall
adjust Executive's base salary if the performance of the Company or the services
of the Executive reasonably merit an adjustment; provided, however, that at all
times Executive's base salary shall be no lower than the highest base salary
paid by the Company to any other Company employee.

     2.2  Bonus Plan. The Executive shall participate in Company's management
bonus pool, with bonus payments to be determined and paid based upon written
performance objectives to be determined by the Compensation Committee of the
Company's Board.

     2.3  Stock Option. As a material inducement to Executive to enter into the
Agreement and this Addendum and as part of Executive's compensation, the Company


                                  Page 3 of 10
                   Hyseq, Inc. - Ted Love Employment Agreement

   9

shall grant Executive a stock option ("Option") to purchase 500,000 shares
("Shares") of Hyseq's common stock at a per share exercise price equal to the
closing price of the Company's common stock on the NASDAQ Stock Market on the
date of grant. The Company represents that it will use every effort to make the
date of grant the Effective Date, or the next business day after the Effective
Date. The Option shall be an incentive stock option to the fullest extent
permitted by law and the Company's Stock Option Plan. The vesting commencement
date for the Option shall be the Effective Date. 150,000 Shares shall vest on
the date of grant. 87,500 Shares shall vest on each one (1) year anniversary of
the Effective Date thereafter, until all Shares are fully vested or Executive's
employment terminates, whichever occurs first, subject in all cases to the
acceleration and other provisions set forth in this Addendum. The Option shall
terminate on the ten (10) year anniversary of the Effective Date and shall be
governed by an option agreement. The Executive shall receive the benefit, with
respect to all options issued to him now or in the future, of any changes in the
Company's stock option vesting schedule. All of Executive's options shall be
amended to provide for prorata monthly vesting after the first anniversary date
of the option in the event any optionee under any Company stock option plan
receives monthly vesting at any time.

     2.4  Put. Provided that Executive has not previously exercised the 150,000
Shares which immediately vest under the Option, at any time after Executive has
been a Company employee for 12 months, but before the third anniversary of
Executive's first day of employment (regardless of whether Executive is employed
by the Company), Executive shall have the right, but not the obligation, to
forfeit the option to purchase 150,000 Shares (and the post termination exercise
period for the 150,000 Shares shall be extended to the third anniversary date of
Executive's employment unless extended for a longer period by Section
3.2(a)(iii)). Immediately on receiving notice that Executive has forfeited his
option to purchase 150,000 Shares, the Company shall pay Executive the sum of
(x) two million dollars ($2,000,000), plus (y) the aggregate amount of all
interest accrued on the Loan (described in Section 2.5 below) up to the date
Company makes the payment required by this paragraph, and on the date the
Company makes the payment required under this Section 2.4 the Loan shall become
immediately due and payable in full. For purposes of this paragraph only, if
Executive's employment terminates before the one year anniversary of the first
date of his employment and the termination is other than for Cause (as defined
below) or Good Reason (as defined below) exists, then Executive will be deemed
to be a Company employee for 12 months, and shall have the right to forfeit the
150,000 Shares until the third anniversary of the first day of his employment
(and the post termination exercise period for the 150,000 Shares shall be
extended to the third anniversary date of Executive's employment).

     2.5  Promissory Note.

          (a)  The Company shall, at Executive's sole discretion, loan Executive
               two million dollars ($2,000,000) (the "Loan"), in increments, and
               at times, chosen by Executive. The interest rate on the Loan
               shall be the lowest applicable federal interest rate (or such
               other higher


                                  Page 4 of 10
                   Hyseq, Inc. - Ted Love Employment Agreement

   10

               rate of interest, if required, to constitute a market rate of
               interest as contemplated by the Rules and Regulations of the
               Financial Accounting Standards Board and the U.S. Securities and
               Exchange Commission) on the day the Loan (or Loan increments) is
               issued. The Loan shall be due and payable five (5) years from the
               Effective Date (the "Loan Due Date"). Interest shall accrue, but
               shall be deferred and all interest and principal shall be due on
               the Loan Due Date. It is the intent of the parties that interest
               accruing and deferred under the Loan not be reportable as taxable
               income to Executive in a year or years prior to the interest
               payment being due pursuant to the Loan.

          (b)  In the event any state or federal taxing agency determines that
               interest is reportable as taxable income to Executive in a year
               or years prior to the Loan Due Date, then Company agrees to
               extend Executive one or more promissory note(s) at the interest
               rate described in 2.5(a) in order to cover the tax, and other
               amount, if any, paid by Executive on this additional taxable
               income.

     2.6  Contingencies. In the event that any statute or regulation or any
contract between Executive and/or Company and any Company underwriter, prevents
Executive and Company from consummating any of the securities transactions
described in Sections 1.1 or 2.4 or 3.2 of this Agreement, then (x) the
transaction shall not take place on the original transaction date, (y) the
transaction shall take place at the first date when legally and contractually
permissible, and (z) Company shall pay Executive the sum that Executive would
have received on the original transaction date (i.e., either the NonPromotion
Date pursuant to Sections 1.1(c) and 1.1(e) or the date of the Put pursuant to
Section 2.4, or the applicable date pursuant to Section 3.2(b)); provided that
in the case of a sale pursuant to Section 2.4 above, (i) Company shall also pay
the aggregate amount of all interest accrued on the Loan between the original
transaction date and the date the transaction takes place pursuant to this
Section 2.6 and (ii) if applicable, the term of the Loan shall be extended until
the first date when the transaction is legally and contractually permissible.

     2.7  Reimbursement of Expenses. The Company shall reimburse Executive for
actual and reasonable business expenses in accordance with Company policy. The
Company shall also reimburse Executive for all reasonable legal and accounting
expenses and all professional membership dues and continuing professional
education in accordance with Company policy. In addition, Company shall
reimburse Executive for all reasonable financial counseling and legal expenses
incurred in connection with the negotiation of the Agreement and this Addendum.

     2.8  Indemnification Agreement. The Company and Executive shall enter into
an indemnification agreement in the form of agreement attached as Exhibit A.

                       TERMINATION AND SEPARATION PACKAGE

     3.1  At Will Employment. Executive and the Company agree that Executive's
employment with the Company is "at-will." This means that either party may
terminate Executive's employment, with or without cause. However, any
termination of Executive's employment shall be subject to the terms and
conditions of the Agreement and this Addendum, including without limitation, the
Company's obligation to pay and/or provide the Separation Package as set forth
in Section 3.2(a) and, if applicable, the additional payments referred to in
Section 3.2(b) of this Addendum.

     3.2  Involuntary Termination, Good Reason to Resign, and Change of Control.

          (a)  Separation Package in the Event of Termination Without Cause
               and/or Good Reason to Resign Exists. In the event that
               Executive's employment terminates (x) other than for Cause
               (defined below) if terminated by the Company, and/or (y) Good
               Reason (defined below) exists for Executive to terminate, then
               the Company shall (i) immediately accelerate the vesting of 100%
               of Executive's then unvested Option Shares so that Executive's
               vested Option Shares and 100% of all unvested Option Shares are
               fully vested and immediately exercisable, (ii) immediately
               accelerate the vesting of 100% of all unvested shares of all
               options issued to and/or granted to Executive in the first four
               (4) years of Executive's employment ("New Option Shares") so that
               Executive's vested New Option Shares and 100% of all unvested New
               Option Shares are fully vested and immediately exercisable, (iii)
               extend by eighteen (18) months the time period Executive has to
               exercise any vested Option Shares and/or New Options Shares, (iv)
               immediately pay Executive, in one lump sum, a sum equal to twelve
               (12) months of Executive's then current base salary, and (v)
               continue the health, disability, and life insurance benefits for
               Executive (including his family) for the twelve (12) months
               following the termination date or Good Reason Termination Date at
               the same level of benefits as existed immediately before the
               termination date or Good Reason Termination Date. The benefits
               set forth in this Section 3.2(a) are referred to as the
               "Separation Package".

          (b)  In addition, in the event (x) Executive has not been Hyseq's
               Chief Executive Officer for at least six (6) months before the
               termination of his employment other than for Cause (defined
               below) and/or Good Reason (defined below) exists, or (y)
               Executive has been promoted to Chief Executive Officer and
               President in anticipation of a Change of Control and is not
               employed as the surviving


                                  Page 6 of 10
                   Hyseq, Inc. - Ted Love Employment Agreement

   12
               entity's Chief Executive Officer and President for at least the
               one (1) year period beginning with the effective date of the
               Change of Control and ending on the one year anniversary of the
               effective date of the Change of Control (unless Executive is
               terminated for Cause), then (i) the Company shall immediately pay
               Executive four million dollars ($4,000,000), less the Stock
               Appreciation (but using the applicable event date instead of the
               NonPromotion Date for purposes of making the calculation) and
               (ii) Executive shall have the right to sell any or all of his
               vested Option Shares to Hyseq pursuant to Section 1.1(e) above
               (but using the applicable event date instead of the NonPromotion
               Date for purposes of determining the beginning of the 60 day
               period).

          (c)  Benefits. Following termination, Executive shall cease to be a
               Company employee and shall not be entitled to any benefits other
               than the Separation Package as set forth in Section 3.2(a) and,
               if applicable, the additional payments referred to in Section
               3.2(b).

          (d)  Termination For Cause and/or Resignation Without Good Reason. In
               the event the Company terminates Executive for "Cause" as "Cause"
               is defined below, and/or Executive terminates without "Good
               Reason" as "Good Reason" is defined below, Executive shall not
               receive the Separation Package. For purposes of the Agreement and
               this Addendum, a resignation tendered by Executive pursuant to a
               direct request of the Board where no Cause exists shall be deemed
               an involuntary termination without Cause, and Executive shall be
               entitled to the Separation Package.

     3.3  Cause. "Cause" shall mean (1) Executive's willful refusal or willful
failure to comply with a lawful instruction of the Board, or (2) Executive's
conviction of any felony involving an act of moral turpitude. The Company may
not terminate Executive for Cause under subsection (1) above unless the Company
gives Executive written notice of its intent to terminate Executive for Cause
with an explicit written explanation for all reasons for the for Cause
termination, and the Company, in good faith, permits Executive thirty (30) days
to cure the alleged wrongs. If the Executive cures the alleged wrongs, within
thirty (30) days of such notice, he cannot be terminated for Cause.


     3.4  Good Reason. "Good Reason" shall mean (1) the material reduction or
material modification of Executive's authority, duties, title or
responsibilities without his prior written consent, provided that a change in
the number of persons reporting to the Executive shall not, by itself,
constitute Good Reason, or (2) the material reduction or material modification
of Executive's base salary, Executive's stock option rights as set forth in this
Agreement or employee benefits without his prior written consent; or (3) any
requirement that Executive move his principal place of employment more than
thirty (30) miles from the Company's current headquarters, unless the relocation
of Executive's


                                  Page 7 of 10
                   Hyseq, Inc. - Ted Love Employment Agreement

   13

principal place of employment by more than thirty (30) miles results in moving
his principal place of employment closer to the Executive's current residence in
Hillsborough, California; or (4) Hyseq's failure to promote Executive to Chief
Executive Officer and President on or before the Promotion Date (unless the
Company had Cause not to promote Executive to CEO); or (5) in the event of a
Change of Control, if Executive is not employed as the surviving entity's Chief
Executive Officer and President for at least the one (1) year period beginning
with the effective date of the Change of Control and ending on the one year
anniversary of the effective date of the Change of Control (unless Executive is
terminated for Cause). Executive shall give the Company written notice of his
intent to resign for Good Reason ("Notice of Good Reason") thirty (30) days
before the date he will terminate his employment ("Good Reason Termination
Date"). In the event the Company disputes that Executive has Good Reason, the
Company shall inform Executive in writing before the Good Reason Termination
Date of every reason that the Company disputes Executive's Good Reason claim. In
the event that the Company disputes the existence of Good Reason, Executive, at
his sole discretion, shall have the right to withdraw his notice of intent to
resign for Good Reason and to continue his employment under the same terms and
conditions as if no Notice of Good Reason had been given.

     3.5  Change of Control. "Change of Control" shall mean (1) any event in
which the Company sells, transfers, or disposes of by other means all or
substantially all of the Company's assets (or consummation of any transaction
having similar effect), or (2) the dissolution or liquidation of the Company, or
(3) any merger, consolidation or transfer of securities of the Company with, to
or into another corporation, entity or person, other than a merger,
consolidation or transfer of securities in which the holders of more than 50% of
the shares of capital stock of the Company outstanding immediately prior to such
transaction continue to hold (either by the voting securities remaining
outstanding or by their being converted into voting securities of the surviving
entity) more than 50% of the total voting power represented by the voting
securities of the Company, or such surviving entity, outstanding immediately
after such transaction.

     3.6  Death. In the event of Executive's death while Executive is an
employee of the Company, the Company shall pay the Separation Package set forth
in Sections 3.2(a)(i), (ii), (iii), (iv) and (v) of this Addendum to Executive's
heirs.

     3.7  Disability. In the event of Executive's Disability for any period of
at least six consecutive months while Executive is an employee of the Company,
the Company shall have the right, which may be exercised in its sole discretion,
to terminate Executive. In the event the Company elects to terminate Executive,
the Company shall pay Executive the Separation Package set forth in Sections
3.2(a)(i), (ii), (iii), (iv) and (v) of this Addendum. For purposes of this
Addendum, "Disability" shall mean the inability of Executive to perform the
employment services called for in this Agreement by reason of physical or mental
illness or incapacity as determined by a physician chosen by Executive and
reasonably satisfactory to Company or its legal representative.

                              ADDITIONAL PROVISIONS

     4.1  Successors, Binding Agreement. The Agreement and this Addendum shall

the Company or by any merger or consolidation, whether or not the Company is the
surviving or resulting corporation, or upon any transfer of all or substantially
all of the assets of the Company. In the event of any such merger, consolidation
or transfer of assets, the provisions of the Agreement and this Addendum shall
bind and inure to the benefit of the surviving or resulting corporation, or the
corporation to which such assets shall have been transferred, as the case may
be; provided, however, that the Company will require any successor to all or
substantially all of the business and/or assets of the Company, by agreement in
form and substance satisfactory to Executive, to expressly assume and agree to
perform the Agreement and the Addendum in the same manner and to the same extent
that the Company would be required to perform it if no such succession had taken
place.

     4.2  No Mitigation. Executive shall have no duty to mitigate any breach of
the Agreement and/or this Addendum.

     4.3  Headings. Section headings in the Agreement and this Addendum are for

shall be given in writing, delivered by a generally recognized overnight express
delivery service, and shall be made to the Company's principal place of
business, attention Legal Department, and to the Executive's residence.

     4.5  Facsimile Signatures. This Addendum may be entered into by facsimile
signatures, and in counterparts, all of which taken together shall constitute
one original Agreement.
