                        MILLENNIUM PHARMACEUTICALS, INC.

                            2000 STOCK INCENTIVE PLAN

1.       PURPOSE

         The purpose of this 2000 Stock Incentive Plan (the "Plan") of
Millennium Pharmaceuticals, Inc., a Delaware corporation (the "Company"), is to
advance the interests of the Company's stockholders by enhancing the Company's
ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing such persons with
equity ownership opportunities and performance-based incentives and thereby
better aligning the interests of such persons with those of the Company's
stockholders. Except where the context otherwise requires, the term "Company"
shall include any of the Company's present or future subsidiary corporations as
defined in Section 424(f) of the Internal Revenue Code of 1986, as amended, and
any regulations promulgated thereunder (the "Code").

2.       ELIGIBILITY

         All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.       ADMINISTRATION, DELEGATION

         (a) ADMINISTRATION BY BOARD OF DIRECTORS. The Plan will be administered
by the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

         (b) DELEGATION TO EXECUTIVE OFFICERS. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Awards and the maximum number of shares for any one
Participant to be made by such executive officers.

<PAGE>

         (c) APPOINTMENT OF COMMITTEES. To the extent permitted by applicable
law, the Board may delegate any or all of its powers under the Plan to one or
more committees or subcommittees of the Board (a "Committee"). All references in
the Plan to the "Board" shall mean the Board or a Committee of the Board or the
executive officer referred to in Section 3(b) to the extent that the Board's
powers or authority under the Plan have been delegated to such Committee or
executive officer.

4.       STOCK AVAILABLE FOR AWARDS

         (a) NUMBER OF SHARES. Subject to adjustment under Section 8, Awards may
be made under the Plan for (i) up to five percent (5%) of the number of shares
of the Company's common stock, $.001 par value per share ("Common Stock") which
are issued and outstanding on April 12, 2000, the date of the Company's 2000
Annual Meeting of Stockholders, plus (ii) an annual increase in the number of
shares available for Awards on the first day of each of January 1, 2001, 2002
and 2003 equal to the lesser of (A) 5% of the number of shares of Common Stock
outstanding on the last business day preceding each of January 1, 2001, 2002 and
2003, respectively or (B) a lesser number of shares determined by the Board of
Directors. The aggregate number of shares available for grants of incentive
stock options under the Plan is the lesser of 10,000,000 shares or the total
number of shares authorized under the Plan.

         If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part or results in
any Common Stock not being issued, the unused Common Stock covered by such Award
shall again be available for the grant of Awards under the Plan, subject,
however, in the case of Incentive Stock Options (as hereinafter defined), to any
limitation required under the Code. Shares issued under the Plan may consist in
whole or in part of authorized but unissued shares or treasury shares.

         (b) PER-PARTICIPANT LIMIT. Subject to adjustment under Section 8, the
maximum number of shares of Common Stock with respect to which an Award may be
granted to any Participant under the Plan shall be 500,000 per calendar year.
The per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code ("Section 162(m)").

5.       STOCK OPTIONS

         (a) GENERAL. The Board may grant options to purchase Common Stock
(each, an "Option") and determine the number of shares of Common Stock to be
covered by each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

         (b) INCENTIVE STOCK OPTIONS. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be

                                      -2-
<PAGE>

granted to employees of the Company and shall be subject to and shall be
construed consistently with the requirements of Section 422 of the Code. The
Company shall have no liability to a Participant, or any other party, if an
Option (or any part thereof) which is intended to be an Incentive Stock Option
is not an Incentive Stock Option.

         (c) EXERCISE PRICE. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement;
PROVIDED, HOWEVER, that the exercise price shall be not less than 100% of the
fair market value of the Common Stock, as determined by the Board, at the time
the Option is granted.

         (d) DURATION OF OPTIONS. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement; PROVIDED, HOWEVER, that no Option will be granted
for a term in excess of 10 years.

         (e) EXERCISE OF OPTION. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

         (f) PAYMENT UPON EXERCISE. Common Stock purchased upon the exercise of
an Option granted under the Plan shall be paid for as follows:

                  (1) in cash or by check, payable to the order of the Company;

                  (2) except as the Board may, in its sole discretion, otherwise
provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price or (ii) delivery by the
Participant to the Company of a copy of irrevocable and unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

                  (3) when the Common Stock is registered under the Exchange Act
of 1934 (the "Exchange Act"), by delivery of shares of Common Stock owned by the
Participant valued at their fair market value as determined by (or in a manner
approved by) the Board in good faith ("Fair Market Value"), provided (i) such
method of payment is then permitted under applicable law and (ii) such Common
Stock was owned by the Participant at least six months prior to such delivery;

                  (4) to the extent permitted by the Board, in its sole
discretion by (i) delivery of a promissory note of the Participant to the
Company on terms determined by the Board, or (ii) payment of such other lawful
consideration as the Board may determine; or

                  (5) by any combination of the above permitted forms of
payment.

                                      -3-
<PAGE>

         (g) SUBSTITUTE OPTIONS. In connection with a merger or consolidation of
an entity with the Company or the acquisition by the Company of property or
stock of an entity, the Board may grant Options in substitution for any options
or other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in the other sections of this Section 5.

6.       RESTRICTED STOCK

         (a) GRANTS. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award");
provided THAT, Restricted Stock Awards and other Awards issued pursuant to
Section 7 below shall be made for no more than 5% of the maximum cumulative
number of shares reserved for issuance under the Plan.

         (b) TERMS AND CONDITIONS. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

7.       OTHER STOCK-BASED AWARDS

         The Board shall have the right to grant other Awards based upon the
Common Stock having such terms and conditions as the Board may determine,
including the grant of shares based upon certain conditions, the grant of
securities convertible into Common Stock and the grant of stock appreciation
rights.

8.       ADJUSTMENTS FOR CHANGES IN COMMON STOCK AND CERTAIN OTHER EVENTS

         (a) CHANGES IN CAPITALIZATION. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities

                                      -4-
<PAGE>

and exercise price per share subject to each outstanding Option, (iv) the
repurchase price per share subject to each outstanding Restricted Stock Award,
and (v) the terms of each other outstanding Award shall be appropriately
adjusted by the Company (or substituted Awards may be made, if applicable) to
the extent the Board shall determine, in good faith, that such an adjustment (or
substitution) is necessary and appropriate. If this Section 8(a) applies and
Section 8(c) also applies to any event, Section 8(c) shall be applicable to such
event, and this Section 8(a) shall not be applicable.

         (b) LIQUIDATION OR DISSOLUTION. In the event of a proposed liquidation
or dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

         (c) ACQUISITION EVENTS

                  (1) Definition. An "Acquisition Event" shall mean: (a) any
merger or consolidation of the Company with or into another entity as a result
of which the Common Stock is converted into or exchanged for the right to
receive cash, securities or other property or (b) any exchange of shares of the
Company for cash, securities or other property pursuant to a statutory share
exchange transaction.

                  (2) Consequences of an Acquisition Event on Options. Upon the
occurrence of an Acquisition Event, or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall provide that all
outstanding Options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an Option shall be considered to be assumed if,
following consummation of the Acquisition Event, the Option confers the right to
purchase, for each share of Common Stock subject to the Option immediately prior
to the consummation of the Acquisition Event, the consideration (whether cash,
securities or other property) received as a result of the Acquisition Event by
holders of Common Stock for each share of Common Stock held immediately prior to
the consummation of the Acquisition Event (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a majority
of the outstanding shares of Common Stock); provided, however, that if the
consideration received as a result of the Acquisition Event is not solely common
stock of the acquiring or succeeding corporation (or an affiliate thereof), the
Company may, with the consent of the acquiring or succeeding corporation,
provide for the consideration to be received upon the exercise of Options to
consist solely of common stock of the acquiring or succeeding corporation (or an
affiliate thereof) equivalent in fair market value to the per share
consideration received by holders of outstanding shares of Common Stock as a
result of the Acquisition Event.

                                      -5-
<PAGE>

         Notwithstanding the foregoing, if the acquiring or succeeding
corporation (or an affiliate thereof) does not agree to assume, or substitute
for, such Options, then the Board shall, upon written notice to the
Participants, provide that all then unexercised Options will become exercisable
in full as of a specified time prior to the Acquisition Event and will terminate
immediately prior to the consummation of such Acquisition Event, except to the
extent exercised by the Participants before the consummation of such Acquisition
Event; provided, however, that in the event of an Acquisition Event under the
terms of which holders of Common Stock will receive upon consummation thereof a
cash payment for each share of Common Stock surrendered pursuant to such
Acquisition Event (the "Acquisition Price"), then the Board may instead provide
that all outstanding Options shall terminate upon consummation of such
Acquisition Event and that each Participant shall receive, in exchange therefor,
a cash payment equal to the amount (if any) by which (A) the Acquisition Price
multiplied by the number of shares of Common Stock subject to such outstanding
Options (whether or not then exercisable), exceeds (B) the aggregate exercise
price of such Options.

                  (3) Consequences of an Acquisition Event on Restricted Stock
Awards. Upon the occurrence of an Acquisition Event, the repurchase and other
rights of the Company under each outstanding Restricted Stock Award shall inure
to the benefit of the Company's successor and shall apply to the cash,
securities or other property which the Common Stock was converted into or
exchanged for pursuant to such Acquisition Event in the same manner and to the
same extent as they applied to the Common Stock subject to such Restricted Stock
Award.

                  (4) Consequences of an Acquisition Event on Other Awards. The
Board shall specify the effect of an Acquisition Event on any other Award
granted under the Plan at the time of the grant of such Award.

9.       GENERAL PROVISIONS APPLICABLE TO AWARDS

         (a) TRANSFERABILITY OF AWARDS. Except as the Board may otherwise
determine or provide in an Award, Awards shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution, and, during the life of the Participant, shall be
exercisable only by the Participant. References to a Participant, to the extent
relevant in the context, shall include references to authorized transferees.

         (b) DOCUMENTATION. Each Award shall be evidenced by a written
instrument in such form as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

         (c) BOARD DISCRETION. Except as otherwise provided by the Plan, each
Award may be made alone or in addition or in relation to any other Award. The
terms of each Award need not be identical, and the Board need not treat
Participants uniformly.

                                      -6-
<PAGE>

         (d) TERMINATION OF STATUS. The Board shall determine the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

         (e) WITHHOLDING. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may, to the extent then permitted under applicable law, satisfy
such tax obligations in whole or in part by delivery of shares of Common Stock,
including shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

         (f) AMENDMENT OF AWARD; PROHIBITION ON REPRICING. The Board may amend,
modify or terminate any outstanding Award, including but not limited to,
substituting therefor another Award of the same or a different type, changing
the date of exercise or realization, and converting an Incentive Stock Option to
a Nonstatutory Stock Option, PROVIDED THAT the Participant's consent to such
action shall be required unless the Board determines that the action, taking
into account any related action, would not materially and adversely affect the
Participant, and FURTHER PROVIDED, that the Board may not amend, modify,
substitute or otherwise change any outstanding Award in order to effect a
decrease in the exercise price thereof.

         (g) CONDITIONS ON DELIVERY OF STOCK. The Company will not be obligated
to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

         (h) ACCELERATION. The Board may at any time provide that any Options
shall become immediately exercisable in full or in part, that any Restricted
Stock Awards shall be free of restrictions in full or in part or that any other
Awards may become exercisable in full or in part or free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

10.      MISCELLANEOUS

                                      -7-
<PAGE>

         (a) NO RIGHT TO EMPLOYMENT OR OTHER STATUS. No person shall have any
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

         (b) NO RIGHTS AS STOCKHOLDER. Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
with respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

         (c) EFFECTIVE DATE AND TERM OF PLAN. The Plan shall become effective on
the date on which it is adopted by the Board, but no Award granted to a
Participant that is intended to comply with Section 162(m) shall become
exercisable, vested or realizable, as applicable to such Award, unless and until
the Plan has been approved by the Company's stockholders to the extent
stockholder approval is required by Section 162(m) in the manner required under
Section 162(m) (including the vote required under Section 162(m)). No Awards
shall be granted under the Plan after the completion of ten years from the
earlier of (i) the date on which the Plan was adopted by the Board or (ii) the
date the Plan was approved by the Company's stockholders, but Awards previously
granted may extend beyond that date.

         (d) AMENDMENT OF PLAN. The Board may amend, suspend or terminate the
Plan or any portion thereof at any time, provided that to the extent required by
Section 162(m), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,
realizable or vested, as applicable to such Award, unless and until such
amendment shall have been approved by the Company's stockholders as required by
Section 162(m) (including the vote required under Section 162(m)), and further
provided that the approval of holders of a majority of the shares of Common
Stock present or represented and voting at the meeting of stockholders called
for such purpose will be required for any amendment to the Plan which (i)
changes the class of persons eligible for the grant of awards, as specified in
Section 2, (ii) increases (unless pursuant to Section 8) the maximum number of
shares subject to awards under the Plan, as specified in Section 4, or (iii)
materially increases the benefits accruing to Participants under the Plan.

                                      -8-
<PAGE>

         (e) GOVERNING LAW. The provisions of the Plan and all Awards made
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.
