                     2000 OUTSIDE DIRECTOR STOCK OPTION PLAN

1.       PURPOSE

         The purpose of this 2000 Outside Director Stock Option Plan (the
"Plan") of The Medicines Company, 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 outside directors of the Company by
providing such directors with equity ownership opportunities and
performance-based incentives and thereby better aligning the interests of such
persons with those of the Company's stockholders.

2.       ELIGIBILITY

         Each director of the Company who is not an employee of the Company (an
"Eligible Director") is eligible to be granted options (an "Option") under the
Plan. Any person who has been granted an Option under the Plan shall be deemed a
"Participant."

3.       ADMINISTRATION, DELEGATION

         The Plan will be administered by the Board of Directors of the Company
(the "Board"). The Board shall have authority 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 Option 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 Option. 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.

4.       STOCK AVAILABLE FOR OPTIONS

         a. NUMBER OF SHARES. Subject to adjustment under Section 4(b), Options
may be granted under the Plan for up to 250,000 shares of common stock, $.001
par value per share, of the Company (the "Common Stock"). If any Option 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 Option shall again be available
for the grant of Options under the Plan. Shares issued under the Plan may
consist in whole or in part of authorized but unissued shares or treasury
shares.

         b. ADJUSTMENT TO COMMON STOCK. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination,
exchange of shares,

liquidation, 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 number
and class of securities and exercise price per share subject to each outstanding
Option and (iii) the number and class of securities available for automatic
grants shall be appropriately adjusted by the Company (or substituted Options
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 4(b) applies and Section 6(c) also applies to any event, Section
6(c) shall be applicable to such event, and this Section 4(b) shall not be
applicable.

         9.4 Shareholder Rights. A Participant shall have all the rights of a
shareholder with respect to Restricted Stock awarded, including voting and
dividend rights, unless otherwise provided in the Award Agreement.

SECTION 10        STOCK UNITS

         10.1 Grant of Stock Units. Subject to the terms and provisions of the
Plan, the Board may award Stock Units subject to such terms, restrictions,
conditions, performance criteria, vesting requirements and payment rules as the
Board shall determine.

         10.2 Consideration. Shares awarded in connection with a Stock Unit
shall be issued for whatever consideration is determined by the Board, subject
to applicable law.

SECTION 11        OTHER AWARDS

         The Board shall have the authority to specify the terms and provisions
of other forms of equity-based or equity-related Awards not described above
which the Board determines to be consistent with the purposes of the Plan and
the interests of the Company, which Awards may provide for cash payments based
in whole or in part on the value or future value of Shares, for the acquisition
or future acquisition of Shares, or any combination thereof. Other Awards may
also include cash payments (including the cash payment of dividend equivalents)
under the Plan which may be based on one or more criteria determined by the
Board that are unrelated to the value of the Shares and that may be granted in
tandem with, or independent of, other Awards under the Plan.

SECTION 12        GENERAL PROVISIONS APPLICABLE TO AWARDS

         12.1 Legal and Regulatory Matters. The delivery of Shares shall be
subject to compliance with (i) applicable federal and state laws and
regulations, (ii) if the outstanding Shares are listed at the time on any stock
exchange or automated quotation system, the listing requirements of such
exchange or system, and (iii) the Company's counsel's approval of all other
legal matters in connection with the issuance and delivery of the Shares. If the
sale of the Shares has not been registered under the 1933 Act, the Company may
require, as a condition to delivery of the Shares, such representations or
agreements as counsel for the Company may consider appropriate to avoid
violation of the 1933 Act and may require that the certificates evidencing the
Shares bear an appropriate legend restricting transfer.

         12.2 Award Agreement. The terms and provisions of an Award shall be set
forth in an Award Agreement approved by the Board and delivered or made
available to the Participant as soon as practicable following the Grant Date.

         12.3 Determination of Restrictions on the Award. The vesting,
exercisability, payment and other restrictions applicable to an Award (which may
include, without limitation, restrictions on transferability or provision for
mandatory resale to the Company) shall be determined by the Board and set forth
in the applicable Award Agreement. Notwithstanding

                                       -7-
<PAGE>   8
the foregoing, the Board may accelerate (i) the vesting or payment of any Award
(including an ISO), (ii) the lapse of restrictions on any Award (including an
Award of Restricted Stock) and (iii) the date on which any Option or SAR first
becomes exercisable.

         12.4 Mergers, etc. Notwithstanding any other provisions of the Plan, in
the event that a transaction occurs that results or will result in the Common
Stock not being registered under Section 12 of the Exchange Act, all Awards
shall terminate upon the completion of the transaction. If the transaction is
intended to be treated as a pooling of interests for accounting purposes, the
Board shall cause the acquiring or surviving corporation or one of its
affiliates to grant replacement Awards to Participants. In all other
transactions, the Board may either arrange for replacement Awards, accelerate
the exercisability of all outstanding Awards (subject to completion of the
transaction) or terminate all Awards in exchange for a cash payment. Replacement
Awards for ISOs shall satisfy any applicable requirements of the Code.

         12.5 Termination of Employment. For purposes of the Plan, the following
events shall not be deemed a termination of employment of a Participant: (i) a
transfer to the employment of the Company from its Parent (if any) or from a
Subsidiary, or from the Company to its Parent (if any) or to a Subsidiary, or
from one Subsidiary to another, or from the Company's Parent (if any) to a
Subsidiary, or from a Subsidiary to the Company's Parent (if any); or (ii) an
approved leave of absence for military service or sickness, or for any other
purpose approved by the Company, if the Participant's right to employment is
guaranteed either by a statute or by contract or under the policy pursuant to
which the leave of absence was granted or if the Board otherwise so provides in
writing. For purposes of the Plan, employees of a Subsidiary or Parent (if any)
shall be deemed to have terminated their employment on the date on which such
Subsidiary or Parent ceases to be a Subsidiary or Parent of the Company, as the
case may be.

       12.6 Date of and Effect of Termination of Employment. The date of a
Participant's termination of employment for any reason shall be determined in
the sole discretion of the Board. The Board shall have full authority to
determine and specify in the applicable Award Agreement the effect, if any, that
a Participant's termination of employment for any reason will have on the
vesting, exercisability, payment or lapse of restrictions applicable to an
outstanding Award.

         12.7 Grant of Awards. Each Award may be made alone, in addition to or
in relation to any other Award. The terms of each Award need not be identical,
and the Board need not treat Participants uniformly.

         12.8 Settlement of Awards. No Shares shall be delivered pursuant to any
exercise of an Award until payment in full of the price therefor, if any, is
received by the Company. Such payment may be made in whole or in part in cash or
by certified or bank check or, to the extent permitted by the Board at or after
the Grant Date, by delivery of a note or Shares, including Restricted Stock,
valued at their Fair Market Value on the date of delivery, or by having the
Company hold back from the Shares to be delivered upon exercise Shares having a
Fair Market Value on the last business day preceding the date of exercise equal
to the purchase price, or by delivery of an unconditional and irrevocable
undertaking by a broker to deliver promptly to the Company sufficient funds to
pay the exercise price, or by any combination of

                                       -8-
<PAGE>   9
the permissible forms of payment, or by such other lawful consideration as the
Board shall determine.

         12.9 Withholding Requirements and Arrangements. The 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 respect of Awards under the Plan no
later than the date of the event creating the tax liability. In the Board's
discretion, such tax obligations may be paid in whole or in part in Shares,
including Shares obtained in connection with the Award creating the tax
obligation, valued at their Fair Market Value on the date of delivery. The
Company may, to the extent permitted by law, deduct any such tax obligations
from any payment of any kind otherwise due to the Participant.

       12.10 No Effect on Employment. The Plan shall not give rise to any right
on the part of any Participant to continue in the employ of the Company, its
Parent (if any) or any Subsidiary. The loss of existing or potential profit in
Awards granted under the Plan shall not constitute an element of damages in the
event of termination of the relationship of a Participant even if the
termination is in violation of an obligation of the Company to the Participant
by contract or otherwise.

       12.11 No Rights as Shareholder. Subject to the provisions of the Plan and
the applicable Award Agreement, no Participant shall have any rights as a
shareholder with respect to any Shares to be distributed under the Plan until he
or she becomes the holder thereof.

       12.12 Adjustments. Upon the happening of any of the following described
events, a Participant's rights with respect to Awards granted hereunder shall be
adjusted as hereinafter provided, unless otherwise specifically provided in the
Award Agreement.

     12.12.1 Stock Splits and Recapitalizations. In the event the Company issues
any of its Shares as a stock dividend upon or with respect to the Shares, or in
the event Shares shall be subdivided or combined into a greater or smaller
number of Shares, or if, upon a merger or consolidation (except those described
in Section 12.4), reorganization, split-up, liquidation, combination,
recapitalization or the like of the Company, Shares shall be exchanged for other
securities of the Company, securities of another entity, cash or other property,
each Participant upon exercising an Award (for the aggregate purchase price to
be paid under the Award) shall be entitled to purchase such number of Shares,
other securities of the Company, securities of such other entity, cash or other
property as the Participant would have received if the Participant had been the
holder of the Shares with respect to which the Award is exercised at all times
between the Grant Date of the Award and the date of its exercise, and
appropriate adjustments shall be made in the purchase price per Share.

     12.12.2 Restricted Stock. If any person owning Restricted Stock receives
new or additional or different shares or securities ("New Securities") in
connection with a corporate transaction described in Section 12.12.1 as a result
of owning such Restricted Stock, the New Securities shall be subject to all of
the conditions and restrictions applicable to the Restricted Stock with respect
to which such New Securities were issued.

         12.12.3 Board Determination. Notwithstanding any provision to the
contrary, no adjustments shall be made pursuant to this Section 12.12 with
respect to ISOs unless (i) the

                                       -9-
<PAGE>   10
Board, after consulting with counsel for the Company, determines that such
adjustments would not constitute a "modification," "extension" or "renewal" of
such ISOs as such terms are defined in Section 424 of the Code, (ii) would cause
any adverse tax consequences for the holders of such ISOs or (iii) the holders
of such ISOs consent to the adjustment. No adjustments to ISOs shall be made for
dividends paid in cash or in property other than securities of the Company.

     12.12.4 Fractional Shares. No fractional Shares shall be issued under the
Plan. Any fractional Shares which, but for this Section, would have been issued
shall be deemed to have been issued and immediately sold to the Company for
their Fair Market Value, and promptly after such deemed issuance and sale the
Participant shall receive from the Company cash in lieu of such fractional
Shares.

     12.12.5 Other Distributions. The Board may adjust the number of Shares
subject to outstanding Awards and the exercise price and the terms of
outstanding Awards to take into consideration material changes in accounting
practices or principles, extraordinary dividends, acquisitions or dispositions
of stock or property, or any other event if it is determined by the Board that
such adjustment is appropriate to avoid distortion in the operation of the Plan.

     12.12.6 Further Adjustment. Upon the happening of any of the events
described in Sections 12.12.1 or 12.12.5, the class and aggregate number of
Shares set forth in Sections 5.1 and 5.3 hereof that are subject to Awards which
previously have been or subsequently may be granted under the Plan shall be
appropriately adjusted to reflect the events described in such Sections. The
Board shall determine the specific adjustments to be made under this Section
12.12.6.

SECTION 13        AMENDMENT AND TERMINATION

         13.1 Amendment, Suspension or Termination of the Plan. The Board may
modify, amend, suspend or terminate the Plan in whole or in part at any time;
provided, however, that no modification, amendment, suspension or termination of
the Plan shall be made without shareholder approval if such approval is
necessary to comply with any applicable tax or regulatory requirement; and
provided, further, that such modification, amendment, suspension or termination
shall not, without a Participant's consent, affect adversely the rights of such
Participant with respect to any Award previously made.

         13.2 Amendment, Suspension or Termination of an Award. The Board may
modify, amend or terminate any outstanding Award, including, without limitation,
substituting therefor another Award of the same or a different type, changing
the date of exercise or realization and converting an ISO to a NQO; provided,
however, 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.
