                        2002 EMPLOYEE STOCK PURCHASE PLAN

                                  JULY 1, 2002
                       (AS AMENDED THROUGH JUNE 30, 2003)

     I. PURPOSE OF THE PLAN

          This Employee Stock Purchase Plan is intended to promote the interests
of Ligand Pharmaceuticals Incorporated, a Delaware corporation, by providing
eligible employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll deduction-based employee stock
purchase plan designed to qualify under Section 423 of the Code.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II. ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423. Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

     III. STOCK SUBJECT TO PLAN

          A. The stock purchasable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares of Common Stock
purchased on the open market. The number of shares of Common Stock reserved for
issuance over the term of the Plan shall be 510,248 shares, consisting of (i)
35,248 shares that remained available for issuance, as of the Effective Date,
under the Predecessor Plan as last approved by the Corporation's stockholders
plus (ii) an additional increase of 75,000 shares that was approved by the
Corporation's stockholders at the 2002 Annual Meeting plus (iii) an additional
400,000 shares approved by the Corporation's stockholders subsequent to the
adoption of the Plan.

          B. Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant on any one Purchase Date and (iii) the number and class of
securities and the price per share in effect under each outstanding purchase
right in order to prevent the dilution or enlargement of benefits thereunder.

     IV. OFFERING PERIODS

          A. Shares of Common Stock shall be offered for purchase under the Plan
through a series of successive offering periods, which shall continue until such
time as (i) the maximum number of shares of Common Stock available for issuance
under the Plan shall have been purchased (ii) the Plan Administrator shall have
terminated the offering period as provided below or (iii) the Plan shall have
been sooner terminated.

          B. Each offering period shall consist of one Purchase Interval or such
other duration (not to exceed twenty-four (24) months) as determined by the Plan
Administrator prior to the start date of such offering period.



          C. Each offering period shall consist of a series of one or more
successive Purchase Intervals. Purchase Intervals shall run from (i) the first
business day in January to the last business day in March each year (ii) from
the first business day in April to the last business day in June each year,
(iii) from the first business day in July to the last business day in September
each year and (iv) from the first business day in October to the last business
day in December each year.

          D. It its sole discretion, the Plan Administrator may provide that,
should the Fair Market Value per share of Common Stock on any Purchase Date
within an offering period be less than the Fair Market Value per share of Common
Stock on the start date of that offering period, then immediately after the
purchase of shares of Common Stock on behalf of the participants in that
offering period on that Purchase Date, that offering period will automatically
terminate, and a new offering period will begin on the next business day, with
all participants in the terminated offering period to be automatically
transferred to the new offering period.

          E. The Plan Administrator may in its discretion terminate any ongoing
offering period with respect to future Purchase Interval(s), effective on a
current or future Purchase Date in such offering period when, in the sole
discretion of the Plan Administrator, such termination would be in the best
interests of the Corporation or its stockholders including without limitation to
assure that the Corporation will not recognize, for financial reporting
purposes, any compensation expense in connection with the shares of Common Stock
offered for purchase under the Plan. Upon such early termination, a new offering
period will begin at the time designated by the Plan Administrator.

     V. ELIGIBILITY

          A. Each individual who is an Eligible Employee on the start date of
any offering period under the Plan may enter that offering period on such start
date or on any subsequent Quarterly Entry Date within that offering period,
provided he or she remains an Eligible Employee.

          B. Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Quarterly Entry Date within that offering period on which he or she
is an Eligible Employee.

          C. The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

          D. Except as otherwise provided in Sections IV.D. and V.A. above, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date. Participants in the
Plan at the expiration of an offering period may be automatically enrolled in
the next offering period at the discretion of the Plan Administrator.

     VI. PAYROLL DEDUCTIONS

          A. The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock during an offering period may be any multiple
of one percent (1%) of the Cash Earnings paid to the Participant during each
Purchase Interval within that offering period, up to a maximum of ten percent
(10%). The deduction rate so authorized shall continue in effect throughout the
offering period, except to the extent such rate is changed in accordance with
the following guidelines:

          (i) The Participant may, at any time during the offering period,
     reduce his or her rate of payroll deduction (or to the extent applicable,
     the percentage of Cash Earnings to serve as his or her lump sum
     contribution for the initial Purchase Interval of the first offering
     period) to become effective as soon as possible after filing the
     appropriate form with the Plan





     Administrator. The Participant may not, however, effect more than one
     (1) such reduction per Purchase Interval.

          (ii) The Participant may, prior to the commencement of any new
     Purchase Interval within the offering period, increase the rate of his or
     her payroll deduction by filing the appropriate form with the Plan
     Administrator. The new rate (which may not exceed the ten percent (10%)
     maximum) shall become effective on the start date of the first Purchase
     Interval following the filing of such form.

          B. Payroll deductions shall begin on the first pay day
administratively feasible following the Participant's Entry Date into the
offering period and shall (unless sooner terminated by the Participant) continue
through the pay day ending with or immediately prior to the last day of that
offering period. The amounts so collected shall be credited to the Participant's
book account under the Plan, but no interest shall be paid on the balance from
time to time outstanding in such account. The amounts collected from the
Participant shall not be required to be held in any segregated account or trust
fund and may be commingled with the general assets of the Corporation and used
for general corporate purposes.

          C. Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D. The Participant's acquisition of Common Stock under the Plan on any
Purchase Date shall neither limit nor require the Participant's acquisition of
Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

     VII. PURCHASE RIGHTS

          A. GRANT OF PURCHASE RIGHTS. A Participant shall be granted a separate
purchase right for each offering period in which he or she participates. The
purchase right shall be granted on the Participant's Entry Date into the
offering period and shall provide the Participant with the right to purchase
shares of Common Stock, in a series of one or more installments over the
remainder of such offering period, upon the terms set forth below. The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall be
automatically exercised in one or more installments on each successive Purchase
Date within the offering period, and shares of Common Stock shall accordingly be
purchased on behalf of each Participant on each such Purchase Date. The purchase
shall be effected by applying the Participant's payroll deductions (or, to the
extent applicable, his or her lump sum contribution) for the Purchase Interval
ending on such Purchase Date to the purchase of whole shares of Common Stock at
the purchase price in effect for the Participant for that Purchase Date.

          C. PURCHASE PRICE. The purchase price per share at which Common Stock
will be purchased on the Participant's behalf on each Purchase Date within the
offering period shall be equal to eighty-five percent (85%) of the lower of (i)
the Fair Market Value per share of Common Stock on the Participant's Entry Date
into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

          D. NUMBER OF PURCHASABLE SHARES. The number of shares of Common Stock
purchasable by a Participant on each Purchase Date during the offering period
shall be the number of whole shares obtained by dividing the amount collected
from the Participant through payroll deductions during the Purchase Interval
ending




with that Purchase Date (or, to the extent applicable, his or her lump sum
contribution for that Purchase Interval) by the purchase price in effect for the
Participant for that Purchase Date. However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed 1,330 shares, subject to periodic adjustments in the event of certain
changes in the Corporation's capitalization. However, the Plan Administrator
shall have the discretionary authority, exercisable prior to the start of any
offering period under the Plan, to increase or decrease the limitations to be in
effect for the number of shares purchasable per Participant and to establish
limitations on the maximum number of shares that may be purchased in total by
all Participants on each Purchase Date during that offering period.

          E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not applied to
the purchase of shares of Common Stock on any Purchase Date because they are not
sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable per Participant or in
total by all Participants on the Purchase Date shall be promptly refunded.

          F. SUSPENSION OF PAYROLL DEDUCTIONS. In the event that a Participant
is, by reason of the accrual limitations in Article VIII, precluded from
purchasing additional shares of Common Stock on one or more Purchase Dates
during the offering period in which he or she is enrolled, then no further
payroll deductions shall be collected from such Participant with respect to
those Purchase Dates. The suspension of such deductions shall not terminate the
Participant's purchase right for the offering period in which he or she is
enrolled, and payroll deductions shall automatically resume on behalf of such
Participant once he or she is again able to purchase shares during that offering
period in compliance with the accrual limitations of Article VIII.

          G. TERMINATION OF PURCHASE RIGHT. The following provisions shall
govern the termination of outstanding purchase rights:

          (i) A Participant may, at any time prior to the next scheduled
     Purchase Date in the offering period, terminate his or her outstanding
     purchase right by filing the appropriate form with the Plan Administrator
     (or its designate), and no further payroll deductions shall be collected
     from the Participant with respect to the terminated purchase right. Any
     payroll deductions collected during the Purchase Interval in which such
     termination occurs shall, at the Participant's election, be immediately
     refunded or held for the purchase of shares on the next Purchase Date. If
     no such election is made at the time such purchase right is terminated,
     then the payroll deductions collected with respect to the terminated right
     shall be refunded as soon as possible.

          (ii) The termination of such purchase right shall be irrevocable, and
     the Participant may not subsequently rejoin the offering period for which
     the terminated purchase right was granted. In order to resume participation
     in any subsequent offering period, such individual must re-enroll in the
     Plan (by making a timely filing of the prescribed enrollment forms) on or
     before his or her scheduled Entry Date into that offering period.

          (iii) Should the Participant cease to remain an Eligible Employee for
     any reason (including death, disability or change in status) while his or
     her purchase right remains outstanding, then that purchase right shall
     immediately terminate, and all of the Participant's payroll deductions for
     the Purchase Interval in which the purchase right so terminates shall be
     immediately refunded. However, should the Participant cease to remain in
     active service by reason of an approved unpaid leave of absence, then the
     Participant shall have the right, exercisable up until the last business
     day of the Purchase Interval in which such leave commences, to (a) withdraw
     all the payroll deductions collected to date on his or her behalf for that
     Purchase Interval or (b) have such funds held for the purchase of shares on
     his or her behalf on the next scheduled Purchase Date. In no event,
     however, shall any further payroll deductions be collected on the
     Participant's behalf during such leave. Upon the Participant's return to
     active service (x)




     within ninety (90) days following the commencement of such leave or
     (y) prior to the expiration of any longer period for which such
     Participant's right to reemployment with the Corporation is guaranteed by
     statute or contract, his or her payroll deductions under the Plan shall
     automatically resume at the rate in effect at the time the leave began,
     unless the Participant withdraws from the Plan prior to his or her return.
     An individual who returns to active employment following a leave of absence
     that exceeds in duration the applicable (x) or (y) time period will be
     treated as a new Employee for purposes of subsequent participation in the
     Plan and must accordingly re-enroll in the Plan (by making a timely filing
     of the prescribed enrollment forms) on or before his or her scheduled Entry
     Date into the offering period.

          H. CHANGE IN CONTROL. Each outstanding purchase right shall
automatically be exercised, immediately prior to the effective date of any
Change in Control, by applying the payroll deductions of each Participant for
the Purchase Interval in which such Change in Control occurs to the purchase of
whole shares of Common Stock at a purchase price per share equal to eighty-five
percent (85%) of the lower of (i) the Fair Market Value per share of Common
Stock on the Participant's Entry Date into the offering period in which such
Change in Control occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Change in Control. However, the
applicable limitation on the number of shares of Common Stock purchasable per
Participant shall continue to apply to any such purchase, but not the limitation
applicable to the maximum number of shares of Common Stock purchasable in total
by all Participants on any one Purchase Date.

          The Corporation shall use its best efforts to provide at least ten
(10) days' prior written notice of the occurrence of any Change in Control, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change in Control.

          I. PRORATION OF PURCHASE RIGHTS. Should the total number of shares of
Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded. In addition, the Plan Administrator may limit the total number of
shares to be issued on any Purchase Date when, in the sole discretion of the
Plan Administrator, such limitation would be in the best interests of the
Corporation or its stockholders, including without limitation to limit or
eliminate any compensation expense to the Corporation in connection with the
shares of Common Stock to be issued under the Plan. In the event of such a
limitation, the Plan Administrator shall make a pro-rata allocation of the
available shares and any appropriate refund as provided above.

          J. ASSIGNABILITY. The purchase right shall be exercisable only by the
Participant and shall not be assignable or transferable by the Participant.

          K. STOCKHOLDER RIGHTS. A Participant shall have no stockholder rights
with respect to the shares subject to his or her outstanding purchase right
until the shares are purchased on the Participant's behalf in accordance with
the provisions of the Plan and the Participant has become a holder of record of
the purchased shares.

     VIII. ACCRUAL LIMITATIONS

          A. No Participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right granted under this Plan and (ii) similar
rights accrued under other employee stock purchase plans (within the meaning of
Code Section 423)) of the Corporation or any Corporate Affiliate, would
otherwise permit such Participant to purchase more than Twenty-Five Thousand
Dollars ($25,000.00) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.




          B. For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:

          (i) The right to acquire Common Stock under each outstanding purchase
     right shall accrue in a series of installments on each successive Purchase
     Date during the offering period on which such right remains outstanding.

          (ii) No right to acquire Common Stock under any outstanding purchase
     right shall accrue to the extent the Participant has already accrued in the
     same calendar year the right to acquire Common Stock under one or more
     other purchase rights at a rate equal to Twenty-Five Thousand Dollars
     ($25,000.00) worth of Common Stock (determined on the basis of the Fair
     Market Value per share on the date or dates of grant) for each calendar
     year such rights were at any time outstanding.

          C. If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions that the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

          D. In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

     IX. EFFECTIVE DATE AND TERM OF THE PLAN

          A. The Plan was adopted by the Board on March 7, 2002, and became
effective at the Effective Time.

          B. The Plan shall serve as the successor to the Predecessor Plan, and
no further purchase rights shall be granted or exercised under the Predecessor
Plan after the Effective Date.

          C. Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in June 2012 or (ii) the date on
which all purchase rights are exercised in connection with a Change in Control.
No further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

     X. AMENDMENT OF THE PLAN

          A. The Board may alter, amend, suspend or terminate the Plan at any
time. However, no such amendment, modification or termination may adversely
affect any purchase rights outstanding under the Plan without the consent of the
affected Plan participant if such Board action shall become effective prior to
the close of the current Purchase Interval. However, the Plan may be amended or
terminated immediately upon Board action, if and to the extent necessary to
assure that the Corporation will not recognize, for financial reporting
purposes, any compensation expense in connection with the shares of Common Stock
offered for purchase under the Plan, should the financial accounting rules
applicable to the Plan at the Effective Time be subsequently revised so as to
require the Corporation to recognize compensation expense in the absence of such
amendment or termination.

          B. In no event may the Board effect any of the following amendments or
revisions to the Plan without the approval of the Corporation's stockholders:
(i) increase the number of shares of Common Stock issuable under the Plan,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) modify the eligibility requirements for participation in
the Plan.




     XI. GENERAL PROVISIONS

          A. All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation; however, each Plan Participant shall bear all
costs and expenses incurred by such individual in the sale or other disposition
of any shares purchased under the Plan.

          B. Nothing in the Plan shall confer upon the Participant any right to
continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

          C. The provisions of the Plan shall be governed by the laws of the
State of California without resort to that State's conflict-of-laws rules.
