Exhibit 10.13
                                                                   -------------

                        Control Delivery Systems, Inc.

                              2001 INCENTIVE PLAN



     1.   GENERAL

     The Plan has been established to advance the interests of the Company by
giving selected Employees, Eligible Directors and other persons (including both
individuals and entities) who provide services to the Company or its Affiliates
Stock-based incentives or incentives based on Performance Criteria.

     2.   ADMINISTRATION

     The Administrator has discretionary authority, subject only to the express
provisions of the Plan, to interpret the Plan; determine eligibility for and
grant Awards; determine, modify or waive the terms and conditions of any Award;
prescribe forms, rules and procedures (which it may modify or waive); and
otherwise do all things necessary to carry out the purposes of the Plan.  Once
an Award has been communicated in writing to a Participant, the Administrator
may not, without the Participant's consent, alter the terms of the Award so as
to affect adversely the Participant's rights under the Award, unless the
Administrator expressly reserved the right to do so in writing at the time of
such communication.  In the case of any Award intended to be eligible for the
performance-based compensation exception under Section 162(m), the Administrator
shall exercise its discretion consistent with qualifying the Award for such
exception.

     3.   LIMITS ON AWARD UNDER THE PLAN

     a.   Number of Shares. A maximum of [_] shares of Stock may be delivered in
          ----------------
satisfaction of Awards under the Plan.   For purposes of the preceding sentence,
shares that have been forfeited in accordance with the terms of the applicable
Award and shares held back in satisfaction of the exercise price or tax
withholding requirements from shares that would otherwise have been delivered
pursuant to an Award shall not be considered to have been delivered under the
Plan.  Also, the number of shares of Stock delivered under an Award shall be
determined net of any previously acquired Shares tendered by the Participant in
payment of the exercise price or of withholding taxes.

                                      -1-


     b.   Type of Shares.  Stock delivered by the Company under the Plan may be
          --------------
authorized but unissued Stock or previously issued Stock acquired by the Company
and held in treasury.  No fractional shares of Stock will be delivered under the
Plan.

     c.   Option & SAR Limits.  The maximum number of shares of Stock for which
          -------------------
Stock Options may be granted to any person in any calendar year, the maximum
number of shares of Stock subject to SARs granted to any person in any calendar
year and the aggregate maximum number of shares of Stock subject to other Awards
that may be delivered to any person in any calendar year shall each be [50% of
the maximum number of shares under the Plan].  For purposes of the preceding
sentence, the repricing of a Stock Option or SAR shall be treated as a new grant
to the extent required under Section 162(m).  Subject to these limitations, each
person eligible to participate in the Plan shall be eligible in any year to
receive Awards covering up to the full number of shares of Stock then available
for Awards under the Plan.

     d.   Other Award Limits.  No more than $[500,000] may be paid to any
          ------------------
individual with respect to any Cash Performance Award in any calendar year.
With respect to any Performance Award other than a Cash Performance Award or a
Stock Option or SAR, the maximum number of shares of Stock or their equivalent
value in cash for any Award shall be [   ] per calendar year.

     4.   ELIGIBILITY AND PARTICIPATION

     The Administrator will select Participants from among those key Employees,
Eligible Directors and other individuals or entities providing services to the
Company or its Affiliates who, in the opinion of the Administrator, are in a
position to make a significant contribution to the success of the Company and
its Affiliates.  Eligibility for ISOs is further limited to those individuals
whose employment status would qualify them for the tax treatment described in
Sections 421 and 422 of the Code.

     5.   RULES APPLICABLE TO AWARDS

     a.   All Awards.
          ----------

          (1)  Terms of Awards.  The Administrator shall determine the terms of
               ---------------
all Awards subject to the limitations provided herein.

          (2)  Transferability Of Awards.  Except as the Administrator otherwise
               -------------------------
provides, Awards may not be transferred (including by sale, assignment, pledge,
hypothecation or other disposition or encumbrance) other than by will or by the
laws of descent and distribution, and during a Participant's lifetime an Award
requiring exercise may be exercised

                                      -2-


only by the Participant (or in the event of the Participant's incapacity, the
person or persons legally appointed to act on the Participant's behalf).

          (3)  Vesting, Etc.  Without limiting the generality of Section 2, and
               -------------
except as provided in Section 5.d. with respect to Stock Options granted to
Eligible Directors, the Administrator may determine the time or times at which
an Award will become free of forfeiture restrictions or become exercisable and
the terms on which an Award requiring exercise will remain exercisable.  Unless
the Administrator provides otherwise, immediately upon the termination of the
Participant's employment or other service relationship with the Company and its
Affiliates, an Award requiring exercise will cease to be exercisable, and all
Awards to the extent not already fully vested will be forfeited, except that:

          (A)  subject to (B) and (C) below, all Stock Options and SARs held by
     the Participant immediately prior to the termination of the Participant's
     employment or other service relationship, to the extent then exercisable,
     will remain exercisable for the lesser of (i) a period of three months or
     (ii) the period ending on the latest date on which such Stock Option or SAR
     could have been exercised without regard to this Section 5.a.(3), and shall
     thereupon terminate;

          (B)  all Stock Options and SARs held by a Participant immediately
     prior to his or her death, to the extent then exercisable, will remain
     exercisable by such Participant's executor or administrator or the person
     or persons to whom the Stock Option or SAR is transferred by will or the
     applicable laws of descent and distribution, for the lesser of (i) a one
     year period ending with the first anniversary of the Participant's death or
     (ii) the period ending on the latest date on which such Stock Option or SAR
     could have been exercised without regard to this Section 5.a.(3) and shall
     thereupon terminate; and

          (C)  all Stock Options and SARs (including those vested and unvested
     Awards) held by a Participant whose employment or other service
     relationship has been terminated for cause (as defined below) may be
     immediately terminated by the Administrator.

Unless the Administrator expressly provides otherwise, a Participant's
"employment or other service relationship with the Company and its Affiliates"
will be deemed to have terminated, in the case of an employee Participant, upon
termination of the Participant's employment with the Company and its Affiliates
(whether or not the Participant continues in the service of the Company or its
Affiliates in some capacity other than that of an employee of the Company or its
Affiliates), and in the case of any other Participant, when the service
relationship in respect of which the Award was granted terminates (whether or
not the Participant continues in the service of the Company or its Affiliates in
some other capacity).  For the purposes of Section 5.a.(3)(C) of this Plan,
cause shall mean cause as determined in the discretion of the Administrator,

                                      -3-


including, but not limited to (a) conduct by a Participant that is harmful to
the business, interests or reputation of the Company or any of its Affiliates,
(b) fraud or dishonesty by the Participant or (c) the commission by the
Participant of a crime, other than a misdemeanor that does not involve fraud,
dishonesty or moral turpitude.

          (4)  Taxes.  The Administrator will make such provision for the
               ------
withholding of taxes as it deems necessary.  The Administrator may, but need
not, hold back shares of Stock from an Award or permit a Participant to tender
previously owned shares of Stock in satisfaction of tax withholding
requirements.

          (5)  Dividend Equivalents, Etc.  The Administrator may provide for the
               --------------------------
payment of amounts in lieu of cash dividends or other cash distributions with
respect to Stock subject to an Award.

          (6)  Rights Limited.  Nothing in the Plan shall be construed as giving
               ---------------
any person the right to continued employment or service with the Company or its
Affiliates, or any rights as a shareholder except as to shares of Stock actually
issued under the Plan.  The loss of existing or potential profit in Awards will
not constitute an element of damages in the event of termination of employment
or service for any reason, even if the termination is in violation of an
obligation of the Company or Affiliate to the Participant.

          (7)  Section 162(m).  In the case of an Award intended to be eligible
               --------------
for the performance-based compensation exception under Section 162(m), the Plan
and such Award shall be construed to the maximum extent permitted by law in a
manner consistent with qualifying the Award for such exception. In the case of a
Performance Award intended to qualify as performance-based for the purposes of
Section 162(m) (other than a Stock Option or SAR with an exercise price at least
equal to the fair market value of the underlying Stock on the date of grant),
the Committee shall in writing preestablish one or more specific Performance
Criteria no later than 90 days after the commencement of the period of service
to which the performance relates (or at such earlier time as is required to
qualify the Award as performance-based under Section 162(m)).  Prior to payment
of any Performance Award (other than a Stock Option or SAR with an exercise
price at least equal to the fair market value of the underlying Stock on the
date of grant) intended to qualify as performance-based under Section 162(m),
the Committee shall certify whether the Performance Criteria have been attained
and such determination shall be final and conclusive.  If the Performance
Criteria with respect to any such Award are not attained, no other Award shall
be provided in substitution of the Performance Award.  The provisions of this
Section 5.a.(7) shall be construed in a manner that is consistent with the
Regulations under Section 162(m).

     b.   Awards Requiring Exercise.
          -------------------------

                                      -4-


          (1)  Time And Manner Of Exercise.  Unless the Administrator expressly
               ----------------------------
provides otherwise, (a) an Award requiring exercise by the holder will not be
deemed to have been exercised until the Administrator receives a written notice
of exercise (in form acceptable to the Administrator) signed by the appropriate
person and accompanied by any payment required under the Award; and (b) if the
Award is exercised by any person other than the Participant, the Administrator
may require satisfactory evidence that the person exercising the Award has the
right to do so.

          (2)  Exercise Price.  The Administrator shall determine the exercise
               --------------
price of each Stock Option provided that each Stock Option intended to qualify
for the performance-based exception under Section 162(m) of the Code and each
ISO must have an exercise price that is not less than the Fair Market Value of
the Stock subject to the Stock Option.  An ISO granted to an Employee described
in Section 422(b)(6) of the Code must have an exercise price that is not less
than 110% of such Fair Market Value.

          (3)  Payment Of Exercise Price, If Any.  Where the exercise of an
               ----------------------------------
Award is to be accompanied by payment, the Administrator may determine the
required or permitted forms of payment, subject to the following: (a) all
payments will be by cash or check acceptable to the Administrator, or, if so
permitted by the Administrator (with the consent of the optionee of an ISO if
permitted after the grant), (i) through the delivery of shares of Stock which
have been outstanding for at least six months (unless the Administrator approves
a shorter period) and which have a fair market value equal to the exercise
price, (ii) by delivery of a promissory note of the person exercising the Award
to the Company, payable on such terms as are specified by the Administrator,
(iii) 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
(iv) by any combination of the foregoing permissible forms of payment; and (b)
where shares of Stock issued under an Award are part of an original issue of
shares, the Award shall require that at least so much of the exercise price as
equals the par value of such shares to be paid other than by delivery of a
personal check or promissory note of the person exercising the Award.

          (4)  ISOs.  No ISO may be granted under the Plan after ________, 2011,
               ----
but ISOs previously granted may extend beyond that date.

     c.   Awards Not Requiring Exercise.  Awards of Restricted Stock and
          -----------------------------
Unrestricted Stock may be made in return for either (i) services determined by
the Administrator to have a value not less than the par value of the Awarded
shares of Stock, or (ii) cash or other property having a value not less than the
par value of the Awarded shares of Stock plus such additional amounts (if any)
as the Administrator may determine payable in such combination and type of cash,
other property (of any kind) or services as the Administrator may determine.

                                      -5-


     d.   Grants of Stock Options to Eligible Directors.
          ---------------------------------------------

          (1)  Automatic Grants.  Beginning on the date on which this Plan is
               -----------------
adopted, each Eligible Director, upon his or her initial election to the Board,
shall be awarded Stock Options covering 2,000 shares of Stock (subject to
adjustment pursuant to Section 6.b. of this Plan) (the "Initial Director
                                                        ----------------
Grant").  Thereafter, on the date of each regular annual meeting of stockholders
- -----
of the Company, each Eligible Director who is reelected or is continuing as a
Director shall be awarded Stock Options covering 550 shares of Stock (subject to
adjustment pursuant to Section 6.b of this Plan) (the "Annual Director Grant").
                                                       ---------------------
The exercise price of each Stock Option granted to an Eligible Director shall be
100% of the Fair Market Value of a share of Stock.  The grant of Stock Options
awarded under this Section 5.d.(1) shall not require any action by the
Administrator.

          (2)  Duration.  The latest date on which a Stock Option granted to an
               ---------
Eligible Director pursuant to Section 5.d.(1) may be exercised is on the [fifth]
anniversary of the date on which such option was granted.

          (3)  Vesting.  Stock Options granted in an Initial Director Grant
               --------
shall become exercisable to the extent of one-third of the shares covered
thereby on the day before each of the first, second and third annual meeting of
the stockholders following the date of the grant. All Stock Options granted in
an Annual Director Grant shall become exercisable on the day before the first
annual meeting of stockholders following the date of the grant.

          (4)  Other Awards.  Notwithstanding any grant of Stock Options that
               -------------
may be made to Eligible Directors pursuant to Section 5.d.(1), the Administrator
shall also have the authority under this Plan to make Awards to Eligible
Directors in such amounts and on such terms as it shall determine, subject to
the limits of Sections 3.c. and 3.d.  Such Awards, as well as Awards made
pursuant to Section 5.d.(1) to the extent provisions therefor are not specified
in Section 5.d., are subject to all of the relevant provisions of this Plan.

     6.   EFFECT OF CERTAIN TRANSACTIONS

     a.   Mergers, Etc.  Immediately prior to a Change in Control (other than a
          ------------
transaction in which the outstanding Awards have been assumed or substituted for
as provided below), all outstanding Awards shall vest and, if relevant, become
exercisable, all Performance Criteria and other conditions to any Award shall be
deemed satisfied, and all deferrals measured by reference to or payable in
shares of Stock shall be accelerated.  With respect to Awards requiring
exercise, holders of such Awards will be given adequate notice prior to the
Change in Control in order that they may have a reasonable time to exercise such
Awards.  Upon consummation of a Change in

                                      -6-


Control, all Awards then outstanding and requiring exercise or delivery shall
terminate unless assumed by an acquiring or surviving entity or its affiliate as
provided below.

     To the extent that the Administrator is able, in the context of a Change in
Control, to provide for substitute or replacement Awards from, or the assumption
of Awards by, the acquiring or surviving entity or its affiliates, it may do so
on such terms as the Administrator determines.

     b.   Changes in and Distributions With Respect to the Stock.
          ------------------------------------------------------

          (1)  Basic Adjustment Provisions.  In the event of a stock dividend,
               ----------------------------
stock split or combination of shares, recapitalization or other change in the
Company's capital structure, the Administrator will make appropriate adjustments
(i) to the maximum number of shares that may be delivered under the Plan under
Section 3.a. and to the maximum share limits described in Sections 3.c. and
3.d.; (ii) to the number and kind of shares of stock or securities subject to
Awards then outstanding or subsequently granted; (iii) to any exercise prices
relating to Awards; (iv) to any eligible Director's Deferred Stock Account; and
(v) to any other provision of Awards affected by such change.

          (2)  Certain Other Adjustments.  The Administrator may also make
               --------------------------
adjustments of the type described in paragraph (1) above to take into account
distributions to common stockholders other than those provided for in Section
6.a. and 6.b.(1), or any other event, if the Administrator determines that
adjustments are appropriate to avoid distortion in the operation of the Plan and
to preserve the value of Awards made hereunder; provided, that no such
adjustment shall be made to the maximum share limits described in Section 3.c.
or 3.d., or otherwise to an Award intended to be eligible for the performance-
based exception under Section 162(m), except to the extent consistent with that
exception, nor shall any change be made to ISOs except to the extent consistent
with their continued qualification under Section 422 of the Code.

          (3)  Continuing Application of Plan Terms.  References in the Plan to
               ------------------------------------
shares of Stock shall be construed to include any stock or securities resulting
from an adjustment pursuant to this Section 6.

     7.   LEGAL CONDITIONS ON DELIVERY OF STOCK

     The Company will not be obligated to deliver any shares of Stock pursuant
to the Plan or to remove any restriction from shares of Stock previously
delivered under the Plan until the Company's counsel has approved all legal
matters in connection with the issuance and delivery of such shares; if the
outstanding Stock is at the time of delivery listed on any stock exchange or

                                      -7-


national market system, the shares to be delivered have been listed or
authorized to be listed on such exchange or system upon official notice of
issuance; and all conditions of the Award have been satisfied or waived.  If the
sale of Stock has not been registered under the Securities Act of 1933, as
amended, the Company may require, as a condition to exercise of the Award, such
representations or agreements as counsel for the Company may consider
appropriate to avoid violation of such Act.  The Company may require that
certificates evidencing Stock issued under the Plan bear an appropriate legend
reflecting any restriction on transfer applicable to such Stock.

     8.   AMENDMENT AND TERMINATION

     The Administrator may at any time or times amend the Plan or any
outstanding Award for any purpose which may at the time be permitted by law, or
may at any time terminate the Plan as to any further grants of Awards; provided,
that (except to the extent expressly required or permitted by the Plan) no such
amendment will, without the approval of the stockholders of the Company,
effectuate a change for which stockholder approval is required in order for the
Plan to continue to qualify under Section 422 of the Code and for Awards to be
eligible for the performance-based exception under Section 162(m).

     9.   NON-LIMITATION OF THE COMPANY'S RIGHTS

     The existence of the Plan or the grant of any Award shall not in any way
affect the Company's right to Award a person bonuses or other compensation in
addition to Awards under the Plan.

     10.  GOVERNING LAW

     The Plan shall be construed in accordance with the laws of the State of
Delaware.

future on specified terms.

     "Eligible Directors":  Directors who are not officers or employees of the

     "Fair Market Value":  In the event that, on the date of a grant, the Stock
is traded on a recognized national stock exchange (an "Exchange") or listed for
quotation on NASDAQ, Fair Market Value shall mean, except as provided below, the
average intraday high and low of a share of Stock as reported on the Exchange or
NASDAQ on the day of the grant (based on The Wall Street Journal report of
                                         -----------------------
composite transactions) or, if the Exchange or NASDAQ was closed on such date,
the next preceding date on which it was open.  If the Stock is not listed on an
Exchange or is not listed for quotation on NASDAQ, Fair Market Value shall have
the same meaning as it does in the provisions of the Code and the regulations

condition for  the exercisability, vesting or full enjoyment of an Award.  For
purposes of Performance Awards that are intended to qualify for the performance-
based compensation exception under Section 162(m), a Performance Criterion shall
mean an objectively determinable measure of performance relating to any of the
following (determined either on a consolidated basis or, as the context permits,
