<PAGE>

      Any Shares subject to Options or SARs shall be counted against the
numerical limits of this Section 3 as one share for every share subject thereto.
Any Shares or units subject to Restricted Stock, Performance Shares, Performance
Units or Deferred Stock Unit Awards with a per share or unit purchase price

Units or Deferred Stock Units, is forfeited to or repurchased by the Company,
the unpurchased Shares (or for Awards other than Options and SARs, the forfeited

respect to SARs, only shares actually issued pursuant to an SAR shall cease to
be available under the Plan; all remaining shares under SARs shall remain

are repurchased by the Company at their original purchase price or are forfeited

Plan. Shares used to pay the exercise price of an Option or Stock Purchase Right
shall become available for future grant or sale under the Plan. To the extent an
Award under the Plan is paid out in cash rather than stock, such cash payment
shall not result in reducing the number of Shares available for issuance under
the Plan.

      4. Administration of the Plan.

            (a) Procedure.

                  (i) Multiple Administrative Bodies. The Plan may be
administered by different Committees with respect to different groups of Service
Providers.

                  (ii) Section 162(m). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                  (iii) Rule 16b-3. To the extent desirable to qualify
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

                  (iv) Other Administration. Other than as provided above, the
Plan shall be administered by (A) the Board or (B) a Committee, which committee
shall be constituted to satisfy Applicable Laws.

                                                                             -6-

<PAGE>

            (b) Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                  (i) to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(u) of the Plan;

                  (ii) to select the Service Providers to whom Awards may be
granted hereunder;

                  (iii) to determine whether and to what extent Awards or any
combination thereof, are granted hereunder;

                  (iv) to determine the number of shares of Common Stock or
equivalent units to be covered by each Award granted hereunder;

                  (v) to approve forms of agreement for use under the Plan;

                  (vi) to determine the terms and conditions, not inconsistent
with the terms of the Plan, of any award granted hereunder. Such terms and
conditions include, but are not limited to, the exercise price, the time or
times when Options or SARs may be exercised or other Awards vest (which may be
based on performance criteria), any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding any Award or the
shares of Common Stock relating thereto, based in each case on such factors as
the Administrator, in its sole discretion, shall determine;

                  (vii) to construe and interpret the terms of the Plan and
Awards;

                  (viii) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of qualifying for preferred tax treatment under
foreign tax laws;

                  (ix) to modify or amend each Award (subject to Section 20(c)
of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options and SARs longer than is
otherwise provided for in the Plan;

                  (x) to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Award previously
granted by the Administrator;

                  (xi) to allow Participants to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares or cash to
be issued upon exercise or vesting of an Award (or distribution of a Deferred
Stock Unit) that number of Shares or cash having a Fair Market Value equal to
the minimum amount required to be withheld (but no more). The Fair Market Value
of any Shares to be withheld shall be determined on the date that the amount of
tax to be withheld is to be determined. All elections by a Participant to have
Shares or cash withheld for this purpose shall be made in such form and under
such conditions as the Administrator may deem necessary or advisable;

                                                                             -7-

                  (xii) to determine the terms and restrictions applicable to
Awards; and

                  (xiii) to make all other determinations deemed necessary or
advisable for administering the Plan.

            (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Participants and any other holders of Awards.

      5. Eligibility. Restricted Stock, Performance Shares, Performance Units,
Stock Appreciation Rights, Deferred Stock Units and Nonstatutory Stock Options
may be granted to Service Providers. Incentive Stock Options may be granted only
to Employees.

      6. No Employment Rights. Neither the Plan nor any Award shall confer upon
a Participant any right with respect to continuing the Participant's employment
with the Company or its Subsidiaries, nor shall they interfere in any way with
the Participant's right or the Company's or Subsidiary's right, as the case may
be, to terminate such employment at any time, with or without cause or notice.

      7. Code Section 162(m) Provisions.

            (a) Option and SAR Annual Share Limit. No Participant shall be
granted, in any Fiscal Year, Options and Stock Appreciation Rights to purchase
more than 400,000 Shares; provided, however, that such limit shall be 1,200,000
Shares in the Participant's first Fiscal Year of Company service.

            (b) Restricted Stock and Performance Share Annual Limit. No
Participant shall be granted, in any Fiscal Year, more than 200,000 Shares of
Restricted Stock or Performance Shares; provided, however, that such limit shall
be 600,000 Shares in the Participant's first Fiscal Year of Company service.

            (c) Performance Units Annual Limit. No Participant shall receive
Performance Units, in any Fiscal Year, having an initial value greater than
$1,000,000, provided, however, that such limit shall be $3,000,000 in the
Participant's first Fiscal Year of Company service.

            (d) Section 162(m) Performance Restrictions. For purposes of
qualifying grants of Restricted Stock, Performance Shares or Performance Units
as "performance-based compensation" under Section 162(m) of the Code, the
Administrator, in its discretion, may set restrictions based upon the
achievement of Performance Goals. The Performance Goals shall be set by the
Administrator on or before the latest date permissible to enable the Restricted
Stock, Performance Shares or Performance Units to qualify as "performance-based
compensation" under Section 162(m) of the Code. In granting Restricted Stock,
Performance Shares or Performance Units which are intended to qualify under
Section 162(m) of the Code, the Administrator shall follow any procedures
determined by it from time to time to be necessary or appropriate to ensure
qualification of the Award under Section 162(m) of the Code (e.g., in
determining the Performance Goals).

                                                                             -8-

            (a) Term . The term of each Option shall be stated in the Notice of
Grant; provided, however, that the term shall be ten (10) years from the date of
grant or such shorter term as may be provided in the Notice of Grant. Moreover,
in the case of an Incentive Stock Option granted to a Participant who, at the
time the Incentive Stock Option is granted, owns stock representing more than
ten percent (10%) of the voting power of all classes of stock of the Company or
any Parent or Subsidiary, the term of the Incentive Stock Option shall be five
(5) years from the date of grant or such shorter term as may be provided in the
Notice of Grant.

            (b) Option Exercise Price. The per share exercise price for the
Shares to be issued pursuant to exercise of an Option shall be determined by the
Administrator and shall be no less than 100% of the Fair Market Value per share
on the date of grant; provided, however, that in the case of an Incentive Stock
Option granted to an Employee who, at the time the Incentive Stock Option is
granted, owns stock representing more than ten percent (10%) of the voting power
of all classes of stock of the Company or any Parent or Subsidiary, the per
Share exercise price shall be no less than 110% of the Fair Market Value per
Share on the date of grant.

            (c) No Repricing. The exercise price for an Option may not be
reduced without the consent of the Company's stockholders. This shall include,
without limitation, a repricing of the Option as well as an Option exchange
program whereby the Participant agrees to cancel an existing Option in exchange
for an Option, SAR or other Award.

            (d) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised. In so doing, the Administrator may specify that an
Option may not be exercised until the completion of a service period or until
performance milestones are satisfied.

            (e) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Subject to
Applicable Laws, such consideration may consist entirely of:

                  (i) cash;

                  (ii) check;

                  (iii) other Shares which (A) in the case of Shares acquired
upon exercise of an option, have been owned by the Participant for more than six

                  (iv) delivery of a properly executed exercise notice together
with such other documentation as the Administrator and the broker, if
applicable, shall require to effect an exercise of the Option and delivery to
the Company of the sale proceeds required to pay the exercise price;

                  (v) any combination of the foregoing methods of payment; or

                  (vi) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

            (f) Exercise of Option; Rights as a Stockholder. Any Option granted
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

      An Option may not be exercised for a fraction of a Share.

      An Option shall be deemed exercised when the Company receives: (i) written
or electronic notice of exercise (in accordance with the Option Agreement) from
the person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised. Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan. Shares issued upon exercise of
an Option shall be issued in the name of the Participant. Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the optioned stock, notwithstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate promptly after the Option is exercised. No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 18 of the
Plan.

      Exercising an Option in any manner shall decrease the number of Shares
thereafter available for sale under the Option, by the number of Shares as to
which the Option is exercised.

            (g) Termination of Relationship as a Service Provider. If a
Participant ceases to be a Service Provider, other than upon the Participant's
death or Disability, the Participant may exercise his or her Option within such
period of time as is specified in the Option Agreement to the extent that the
Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Option Agreement). In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for three months following the Participant's termination. If, on the
date of termination, the Participant is not vested as to his or her entire
Option, the Shares covered by the unvested portion of the Option shall revert to
the Plan. If, after termination, the Participant does not exercise his or her
Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                                                                            -10-

<PAGE>

            (h) Disability. If a Participant ceases to be a Service Provider as
a result of the Participant's Disability, the Participant may exercise his or
her Option within such period of time as is specified in the Option Agreement to
the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the
Participant's termination. If, on the date of termination, the Participant is
not vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Participant does not exercise his or her Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

            (i) Death of Participant. If a Participant dies while a Service
Provider, the Option may be exercised following the Participant's death within
such period of time as is specified in the Option Agreement (but in no event may
the option be exercised later than the expiration of the term of such Option as
set forth in the Option Agreement), by the Participant's designated beneficiary,
provided such beneficiary has been designated prior to Participant's death in a
form acceptable to the Administrator. If no such beneficiary has been designated
by the Participant, then such Option may be exercised by the personal
representative of the Participant's estate or by the person(s) to whom the
Option is transferred pursuant to the Participant's will or in accordance with
the laws of descent and distribution. In the absence of a specified time in the
Option Agreement, the Option shall remain exercisable for twelve (12) months
following Participant's death. If the Option is not so exercised within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

            (j) ISO $100,000 Rule. Each Option shall be designated in the Notice
of Grant as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value:

                  (i) of Shares subject to a Participant's Incentive Stock
Options granted by the Company, any Parent or Subsidiary, which

                  (ii) become exercisable for the first time during any calendar
year (under all plans of the Company or any Parent or Subsidiary) exceeds
$100,000, such excess Options shall be treated as Nonstatutory Stock Options.
For purposes of this Section 9(j), Incentive Stock Options shall be taken into
account in the order in which they were granted, and the Fair Market Value of
the Shares shall be determined as of the time of grant.

      10. Stock Appreciation Rights.

            (a) Grant of SARs. Subject to the terms and conditions of the Plan,
SARs may be granted to Participants at any time and from time to time as shall
be determined by the Administrator, in its sole discretion. The Administrator
shall have complete discretion to determine the number of SARs granted to any
Participant.

            (b) Exercise Price and other Terms. Subject to Section 7(a) of the
Plan, the Administrator, subject to the provisions of the Plan, shall have
complete discretion to determine the

                                                                            -11-

<PAGE>

terms and conditions of SARs granted under the Plan; provided, however, that no
SAR may have a term of more than ten (10) years from the date of grant. The
exercise price for the Shares or cash to be issued pursuant to an already
granted SAR may not be changed without the consent of the Company's
stockholders. This shall include, without limitation, a repricing of the SAR as
well as an SAR exchange program whereby the Participant agrees to cancel an
existing SAR in exchange for an Option, SAR or other Award.

            (c) Payment of SAR Amount. Upon exercise of a SAR, a Participant
shall be entitled to receive payment from the Company in an amount determined by
multiplying:

                  (i) The difference between the Fair Market Value of a Share on
the date of exercise over the exercise price; times

                  (ii) the number of Shares with respect to which the SAR is
exercised.

            (d) Payment upon Exercise of SAR. At the discretion of the
Administrator, payment for a SAR may be in cash, Shares or a combination
thereof.

            (e) SAR Agreement. Each SAR grant shall be evidenced by an Award
Agreement that shall specify the exercise price, the term of the SAR, the
conditions of exercise, and such other terms and conditions as the
Administrator, in its sole discretion, shall determine.

            (f) Expiration of SARs. A SAR granted under the Plan shall expire
upon the date determined by the Administrator, in its sole discretion, and set
forth in the Award Agreement.

            (g) Termination of Relationship as a Service Provider. If a
Participant ceases to be a Service Provider, other than upon the Participant's
death or Disability termination, the Participant may exercise his or her SAR
within such period of time as is specified in the SAR Agreement to the extent
that the SAR is vested on the date of termination (but in no event later than
the expiration of the term of such SAR as set forth in the SAR Agreement). In
the absence of a specified time in the SAR Agreement, the SAR shall remain
exercisable for three months following the Participant's termination. If, on the
date of termination, the Participant is not vested as to his or her entire SAR,
the Shares covered by the unvested portion of the SAR shall revert to the Plan.
If, after termination, the Participant does not exercise his or her SAR within
the time specified by the Administrator, the SAR shall terminate, and the Shares
covered by such SAR shall revert to the Plan.

            (h) Disability. If a Participant ceases to be a Service Provider as
a result of the Participant's Disability, the Participant may exercise his or
her SAR within such period of time as is specified in the SAR Agreement to the
extent the SAR is vested on the date of termination (but in no event later than
the expiration of the term of such SAR as set forth in the SAR Agreement). In
the absence of a specified time in the SAR Agreement, the SAR shall remain
exercisable for twelve (12) months following the Participant's termination. If,
on the date of termination, the Participant is not vested as to his or her
entire SAR, the Shares covered by the unvested portion of the SAR shall revert
to the Plan. If, after termination, the Participant does not exercise his or her
SAR within the time specified herein, the SAR shall terminate, and the Shares
covered by such SAR shall revert to the Plan.

                                                                            -12-

<PAGE>

                  (i) Death of Participant. If a Participant dies while a
Service Provider, the SAR may be exercised following the Participant's death
within such period of time as is specified in the SAR Agreement (but in no event
may the SAR be exercised later than the expiration of the term of such SAR as
set forth in the SAR Agreement), by the Participant's designated beneficiary,
provided such beneficiary has been designated prior to Participant's death in a
form acceptable to the Administrator. If no such beneficiary has been designated
by the Participant, then such SAR may be exercised by the personal
representative of the Participant's estate or by the person(s) to whom the SAR
is transferred pursuant to the Participant's will or in accordance with the laws
of descent and distribution. In the absence of a specified time in the SAR
Agreement, the SAR shall remain exercisable for twelve (12) months following
Participant's death. If the SAR is not so exercised within the time specified
herein, the SAR shall terminate, and the Shares covered by such SAR shall revert
to the Plan.

      11. Restricted Stock.

            (a) Grant of Restricted Stock. Subject to the terms and conditions
of the Plan, Restricted Stock may be granted to Participants at any time as
shall be determined by the Administrator, in its sole discretion. Subject to
Section 7(b) hereof, the Administrator shall have complete discretion to
determine (i) the number of Shares subject to a Restricted Stock award granted
to any Participant, and (ii) the conditions that must be satisfied, which
typically will be based principally or solely on continued provision of services
but may include a performance-based component, upon which is conditioned the
grant, vesting or issuance of Restricted Stock. Restricted Stock shall be
granted in the form of units to acquire Shares. Each such unit shall be the
equivalent of one Share for purposes of determining the number of Shares subject
to an Award. Restricted Stock may be granted in the form of restricted stock
units that are not issued until the vesting conditions are satisfied. Until the
Shares are issued, no right to vote or receive dividends or any other rights as
a stockholder shall exist with respect to the units to acquire Shares.

            (b) Other Terms. The Administrator, subject to the provisions of the
Plan, shall have complete discretion to determine the terms and conditions of
Restricted Stock granted under the Plan. Restricted Stock grants shall be
subject to the terms, conditions, and restrictions determined by the
Administrator at the time the stock or the restricted stock unit is awarded. The
Administrator may require the recipient to sign a Restricted Stock Award
agreement as a condition of the award. Any certificates representing the Shares
of stock awarded shall bear such legends as shall be determined by the
Administrator.

            (c) Restricted Stock Award Agreement. Each Restricted Stock grant
shall be evidenced by an agreement that shall specify the purchase price (if
any) and such other terms and conditions as the Administrator, in its sole
discretion, shall determine; provided; however, that if the Restricted Stock
grant has a purchase price, such purchase price must be paid no more than ten
(10) years following the date of grant.

      12. Performance Shares.

            (a) Grant of Performance Shares. Subject to the terms and conditions
of the Plan, Performance Shares may be granted to Participants at any time as
shall be determined by the

                                                                            -13-

<PAGE>

Administrator, in its sole discretion. Subject to Section 7(b) hereof, the
Administrator shall have complete discretion to determine (i) the number of
Shares subject to a Performance Share award granted to any Participant, and (ii)
the conditions that must be satisfied, which typically will be based principally
or solely on achievement of performance milestones but may include a
service-based component, upon which is conditioned the grant or vesting of
Performance Shares. Performance Shares shall be granted in the form of units to
acquire Shares. Each such unit shall be the equivalent of one Share for purposes
of determining the number of Shares subject to an Award. Until the Shares are
issued, no right to vote or receive dividends or any other rights as a
stockholder shall exist with respect to the units to acquire Shares.

            (b) Other Terms. The Administrator, subject to the provisions of the
Plan, shall have complete discretion to determine the terms and conditions of
Performance Shares granted under the Plan. Performance Share grants shall be
subject to the terms, conditions, and restrictions determined by the
Administrator at the time the stock is awarded, which may include such
performance-based milestones as are determined appropriate by the Administrator.
The Administrator may require the recipient to sign a Performance Shares
agreement as a condition of the award. Any certificates representing the Shares
of stock awarded shall bear such legends as shall be determined by the
Administrator.

            (c) Performance Share Award Agreement. Each Performance Share grant
shall be evidenced by an agreement that shall specify such other terms and
conditions as the Administrator, in its sole discretion, shall determine.

      13. Performance Units.

            (a) Grant of Performance Units. Performance Units are similar to
Performance Shares, except that they shall be settled in a cash equivalent to
the Fair Market Value of the underlying Shares, determined as of the vesting
date. Subject to the terms and conditions of the Plan, Performance Units may be
granted to Participants at any time and from time to time as shall be determined
by the Administrator, in its sole discretion. The Administrator shall have
complete discretion to determine the conditions that must be satisfied, which
typically will be based principally or solely on achievement of performance
milestones but may include a service-based component, upon which is conditioned
the grant or vesting of Performance Units. Performance Units shall be granted in
the form of units to acquire Shares. Each such unit shall be the cash equivalent
of one Share of Common Stock. No right to vote or receive dividends or any other
rights as a stockholder shall exist with respect to Performance Units or the
cash payable thereunder.

            (b) Number of Performance Units. Subject to Section 7(c) hereof, the
Administrator will have complete discretion in determining the number of
Performance Units granted to any Participant.

            (c) Other Terms. The Administrator, subject to the provisions of the
Plan, shall have complete discretion to determine the terms and conditions of
Performance Units granted under the Plan. Performance Unit grants shall be
subject to the terms, conditions, and restrictions determined by the
Administrator at the time the grant is awarded, which may include such
performance-based milestones as are determined appropriate by the Administrator.
The

                                                                            -14-

<PAGE>

Administrator may require the recipient to sign a Performance Unit agreement as
a condition of the award. Any certificates representing the units awarded shall
bear such legends as shall be determined by the Administrator.

            (d) Performance Unit Award Agreement. Each Performance Unit grant
shall be evidenced by an agreement that shall specify such terms and conditions
as the Administrator, in its sole discretion, shall determine.

      14. Deferred Stock Units.

            (a) Description. Deferred Stock Units shall consist of a Restricted
Stock, Performance Share or Performance Unit Award that the Administrator, in
its sole discretion permits to be paid out in installments or on a deferred
basis, in accordance with rules and procedures established by the Administrator.
Deferred Stock Units shall remain subject to the claims of the Company's general
creditors until distributed to the Participant.

            (b) 162(m) Limits. Deferred Stock Units shall be subject to the
annual 162(m) limits applicable to the underlying Restricted Stock, Performance
Share or Performance Unit Award as set forth in Section 7 hereof.

      15. Leaves of Absence. Unless the Administrator provides otherwise or
except as otherwise required by Applicable Laws, vesting of Awards granted
hereunder shall cease commencing on the first day of any unpaid leave of absence
and shall only recommence upon return to active service.

      16. Part-Time Service. Unless the Administrator provides otherwise or
except as otherwise required by Applicable Laws, any service-based vesting of
Awards granted hereunder shall be extended on a proportionate basis in the event
an Employee transitions to a work schedule under which they are customarily
scheduled to work on less than a full-time basis, or if not on a full-time work
schedule, to a schedule requiring fewer hours of service. Such vesting shall be
proportionately re-adjusted prospectively in the event that the Employee
subsequently becomes regularly scheduled to work additional hours of service.

      17. Non-Transferability of Awards. Unless determined otherwise by the
Administrator, an Award may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
recipient, only by the recipient. If the Administrator makes an Award
transferable, such Award shall contain such additional terms and conditions as
the Administrator deems appropriate.

      18. Adjustments Upon Changes in Capitalization, Dissolution or Liquidation
or Change of Control.

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Award, the number of shares of Common Stock which have been
authorized for issuance under the Plan but as to which no Awards have yet been
granted or which have been returned to the Plan upon

                                                                            -15-

<PAGE>

cancellation or expiration of an Award, as well as the price per share of Common
Stock covered by each such outstanding Award and the 162(m) fiscal year share
issuance limits under Sections 7(a) and (b) hereof shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the
Compensation Committee, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an Award.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Participant as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for a Participant
to have the right to exercise his or her Option or SAR until ten (10) days prior
to such transaction as to all of the Awarded Stock covered thereby, including
Shares as to which the Award would not otherwise be exercisable. In addition,
the Administrator may provide that any Company repurchase option or forfeiture
rights applicable to any Award shall lapse 100%, and that any Award vesting
shall accelerate 100%, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised (with respect to Options and SARs) or vested (with respect
to other Awards), an Award will terminate immediately prior to the consummation
of such proposed action.

            (c) Change of Control.

                  (i) Stock Options and SARs. In the event of a Change of
Control, each outstanding Option and SAR shall be assumed or an equivalent
option or SAR substituted by the successor corporation or a Parent or Subsidiary
of the successor corporation. In the event that the successor corporation
refuses to assume or substitute for the Option or SAR, the Participant shall
fully vest in and have the right to exercise the Option or SAR as to all of the
Awarded Stock, including Shares as to which it would not otherwise be vested or
exercisable. If an Option or SAR becomes fully vested and exercisable in lieu of
assumption or substitution in the event of a Change of Control, the
Administrator shall notify the Participant in writing or electronically that the
Option or SAR shall be fully vested and exercisable for a period of fifteen (15)
days from the date of such notice, and the Option or SAR shall terminate upon
the expiration of such period. For the purposes of this paragraph, the Option or
SAR shall be considered assumed if, following the Change of Control, the option
or stock appreciation right confers the right to purchase or receive, for each
Share of Awarded Stock subject to the Option or SAR immediately prior to the
Change of Control, the consideration (whether stock, cash, or other securities
or property) received in the Change of Control by holders of Common Stock for
each Share held on the effective date of the transaction (and if holders were
offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding Shares); provided, however, that if
such consideration received in the Change of Control is not solely common stock
of the successor corporation or its Parent, the

                                                                            -16-

<PAGE>

Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option or SAR, for
each Share of Awarded Stock subject to the Option or SAR, to be solely common
stock of the successor corporation or its Parent equal in fair market value to
the per share consideration received by holders of Common Stock in the Change of
Control.

                  (ii) Restricted Stock, Performance Shares, Performance Units
and Deferred Stock Units. In the event of a Change of Control, each outstanding
Restricted Stock, Performance Share, Performance Unit and Deferred Stock Unit
award shall be assumed or an equivalent Restricted Stock, Performance Share,
Performance Unit and Deferred Stock Unit award substituted by the successor
corporation or a Parent or Subsidiary of the successor corporation. In the event
that the successor corporation refuses to assume or substitute for the
Restricted Stock, Performance Share, Performance Unit or Deferred Stock Unit
award, the Participant shall fully vest in the Restricted Stock, Performance
Share, Performance Unit or Deferred Stock Unit including as to Shares (or with
respect to Performance Units, the cash equivalent thereof) which would not
otherwise be vested. For the purposes of this paragraph, a Restricted Stock,
Performance Share, Performance Unit and Deferred Stock Unit award shall be
considered assumed if, following the Change of Control, the award confers the
right to purchase or receive, for each Share (or with respect to Performance
Units, the cash equivalent thereof) subject to the Award immediately prior to
the Change of Control, the consideration (whether stock, cash, or other
securities or property) received in the Change of Control by holders of Common
Stock for each Share held on the effective date of the transaction (and if
holders were offered a choice of consideration, the type of consideration chosen
by the holders of a majority of the outstanding Shares); provided, however, that
if such consideration received in the Change of Control is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received, for each Share and each unit/right to acquire a Share subject to the
Award, to be solely common stock of the successor corporation or its Parent
equal in fair market value to the per share consideration received by holders of
Common Stock in the Change of Control.

      19. Date of Grant. The date of grant of an Award shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Award, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Participant within a
reasonable time after the date of such grant.

      20. Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or terminate the Plan; provided, however, that the Board
may not materially amend the Stock Plan without obtaining stockholder approval.

                  (b) Stockholder Approval. The Company shall obtain stockholder
approval of any Plan amendment to the extent necessary and desirable to comply
Section 422 of the Code (or any successor rule or statute or other applicable
law, rule or regulation, including the requirements of any exchange or quotation
system on which the Common Stock is listed or quoted). Such

                                                                            -17-

<PAGE>

stockholder approval, if required, shall be obtained in such a manner and to
such a degree as is required by the applicable law, rule or regulation.

                  (c) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any
Participant, unless mutually agreed otherwise between the Participant and the
Administrator, which agreement must be in writing (or electronic format) and
signed by the Participant and the Company.

      21. Conditions Upon Issuance of Shares.

            (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Award unless the exercise of the Award or the issuance and
delivery of such Shares (or with respect to Performance Units, the cash
equivalent thereof) shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

            (b) Investment Representations. As a condition to the exercise or
receipt of an Award, the Company may require the person exercising or receiving
such Award to represent and warrant at the time of any such exercise or receipt
that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for
the Company, such a representation is required.

      22. Liability of Company.

            (a) Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

            (b) Grants Exceeding Allotted Shares. If the Awarded Stock covered
by an Award exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional stockholder approval, such Award shall
be void with respect to such excess Awarded Stock, unless stockholder approval
of an amendment sufficiently increasing the number of Shares subject to the Plan
is timely obtained in accordance with Section 20(b) of the Plan.

      23. Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

                                                                            -18-EXHIBIT 10.1

            1.    ASSIGNMENT OF ASSIGNED INTEREST.  Assignor hereby sells,
assigns, transfers, conveys and delivers to Assignee, free and clear from
any liens, encumbrances or defects of title, and Assignee hereby accepts,
acquires and takes assignment and delivery of, the Assigned Interest,
including, but not limited to, all right, title and interest in and to and
claims against the properties (real and personal), capital, cash flow
distributions, profits and losses of the Partnership relating or allocable
to the Assigned Interest.

            2.    PURCHASE PRICE.  In consideration of the sale,
assignment, transfer, conveyance and delivery of the Assigned Interest,
upon the execution hereof Assignee shall pay to Assignor cash in the amount
of $16,559,786, determined in accordance with SCHEDULE A hereto and as
adjusted in accordance with Section 4 below (the "Purchase Price").  The

            3.    EFFECTIVE DATE.  The assignment herein made is effective
as of the date of this Assignment (the "Effective Date").  For all periods
up to, but not including, the Effective Date, that portion of the net
profits or net losses of the Partnership that are allocable to the Assigned
Interest in accordance with the Partnership Agreement shall be credited,
charged or distributed, as the case may be, to Assignor and not to Assignee
and, for all periods from and after the Effective Date, as more fully
described in Section 4 and Section 12, that portion of the net profits or
net losses of the Partnership allocable to the Assigned Interest shall be
credited, charged or distributed, as the case may be, to Assignee and not
to Assignor.

            4.    PRORATIONS.

            (a)   On or prior to January 31, 2005, Assignor and Assignee
      shall determine the prorations set forth in this Section 4.  Any
      payments owing as a result of such prorations shall be made as soon
      as reasonably practicable after such determination is reached.  For
      purposes of making the prorations, the Effective Date shall belong to
      Assignee and all prorations hereinafter provided to be made as of the
      Effective Date shall each be made as of the end of the day before the
      Effective Date.  In each such proration set forth below, the portion
      thereof applicable to periods beginning as of the Effective Date
      shall be credited or charged to Assignee and the portion thereof
      applicable to periods ending immediately prior to the Effective Date
      shall be credited or charged to Assignor.

                  1.    TAXES AND ASSESSMENTS.  General real estate taxes
            and assessments imposed by governmental authority and any
            assessments imposed by private covenant constituting a lien or
            charge on the Community for all tax periods through and
            including the then current calendar year or other current tax
            period (collectively, "Taxes") not yet due and payable shall be
            prorated; PROVIDED, HOWEVER, that an initial estimated
            proration of Taxes for all periods prior to the Effective Date
            has been reflected in the Purchase Price as set forth on
            SCHEDULE A hereto.  If a final tax bill for any period is
            available prior to the proration under this Section 4(a), the
            Taxes for such period shall be allocated on a fair and
            equitable basis according to this Section 4(a) as a final
            proration, with a final and complete proration of Taxes for all
            other tax periods, for which final tax bills are not available
            prior to the proration under this Section 4(a), to be made
            pursuant to Section 4(b); PROVIDED, that, if the final tax
            bills for all periods are available prior to the proration
            under this Section 4(a), the Taxes and all other items to be
            prorated shall be allocated on a fair and equitable basis
            according to this Section 4(a) as a final proration.

                  2.    REVENUES.  All collected rent and other collected
            income (and any applicable state or local tax on rent) under
            apartment leases in effect on or prior to the Effective Date
            shall be prorated.  Uncollected rent and other income shall not
            be prorated.  Assignee agrees to make all reasonable efforts to
            collect, and to cause the Partnership to collect, any rents
            applicable to the period prior to the Effective Date.  Such
            rents paid by tenants on or after the Effective Date relating
            to their occupancy of the Community prior to the Effective Date
            shall be prorated on an if, as and when collected basis
            (without delaying such proration until January 31, 2005 or any
            earlier date).  Any amount collected by Assignee on or after
            the Effective Date from tenants who owe rent for periods prior
            to the Effective Date shall be applied (i) first, in payment of
            rent for the period (if any) after the month in which the
            Effective Date occurs through the end of the month in which
            such amount is collected if the rent for such month is then due

                                      2

<PAGE>

            and payable, (ii) second, in payment of rent for the month in
            which the Effective Date occurs, and (iii) third, in payment of
            rent for the months preceding the month in which the Effective
            Date occurs to the extent rent for such months preceding the
            Effective Date remains unpaid.  Any prepaid rents for the
            period on or after the Effective Date shall be credited to
            Assignee.

                  3.    UTILITIES.  Utilities, including water, sewer,
            electric, and gas, based upon the last reading of meters prior
            to the Effective Date shall be prorated.  The Partnership shall
            endeavor to obtain meter readings on the day before the
            Effective Date, and if such readings are obtained, the
            proration of such items shall be based upon such readings.

                  4.    FEES AND CHARGES UNDER SERVICE CONTRACTS.  Fees and
            charges under contracts for the provision of services to the
            Partnership based upon the periods to which such service
            contracts relate shall be prorated.

                  5.    EXPENSES; CASH.  All other costs and expenses of
            the Partnership not otherwise specifically set forth in this
            Section 4(a) shall be prorated; provided, however, the parties
            acknowledge and agree that the costs of winding up the
            Partnership and preparing the final tax returns for the
            Partnership shall be borne as if incurred immediately before
            the Effective Date.

            (b)   If a final proration with respect to any Taxes cannot be
      made under this Section 4 on or before January 31, 2005, then
      Assignee and Assignor agree to perform a final proration of such
      Taxes and any other remaining undetermined items on a fair and
      equitable basis as soon as the applicable tax bills for such tax
      periods (or the applicable bills for such other remaining
      undetermined items) are available, with final adjustment to be made
      as soon as reasonably possible thereafter.  Payments in connection
      with the final adjustment shall be made as soon as reasonably
      practicable after such final adjustment is agreed upon.

            (c)   Assignor shall have reasonable access to, and the right
      to inspect and audit, the Partnership's books to confirm the
      prorations.  Any such audit shall be at Assignor's sole cost and
      expense.

            5.    REPRESENTATIONS OF ASSIGNOR.  Assignor hereby represents
and warrants to Assignee that:

            (a)   Assignor is duly organized and validly existing under the
      laws of the state of its organization and has been duly authorized by
      all necessary and appropriate action to enter into this Assignment
      and to consummate the transactions contemplated hereby.  This
      Assignment is a valid and binding obligation of Assignor, enforceable
      against Assignor in accordance with its terms, except insofar as
      enforceability may be affected by bankruptcy, insolvency or similar
      laws affecting creditor's rights generally and the availability of
      any particular equitable remedy.

            (b)   Assignor is the record and beneficial owner of all of the
      Assigned Interest, free and clear of any lien, claim, option, call,
      right of first refusal, charge, encumbrance, restriction on transfer
      (other than any restriction under the Securities Act of 1933, as
      amended, or state securities or "blue sky" laws) or other right of
      any other party.  The Assigned Interest represents all of Assignor's
      ownership interest in the Partnership.

                                      3

<PAGE>

            (c)   Assignor's execution and delivery of this Assignment, its
      performance of its obligations hereunder and its consummation and the
      validity of the transactions contemplated hereby do not require it to
      obtain any consent, approval or action of, or make any filing with or
      give any notice to, any corporation, person or firm or any public,
      governmental or regulatory body or judicial authority, which has not
      been previously obtained.

            6.    REPRESENTATIONS OF ASSIGNEE.  Assignee hereby represents
and warrants to Assignor that:

            (a)   Assignee is duly organized and validly existing under the
      laws of the state of its organization and has been duly authorized by
      all necessary and appropriate action to enter into this Assignment
      and to consummate the transactions contemplated hereby.  This
      Assignment is a valid and binding obligation of Assignee, enforceable
      against Assignee in accordance with its terms, except insofar as
      enforceability may be affected by bankruptcy, insolvency or similar
      laws affecting creditor's rights generally and the availability of
      any particular equitable remedy.

            (b)   Assignee's execution and delivery of this Assignment, its
      performance of its obligations hereunder and its consummation and the
      validity of the transactions contemplated hereby do not require it to
      obtain any consent, approval or action of, or make any filing with or
      give any notice to, any corporation, person or firm or any public,
      governmental or regulatory body or judicial authority, which has not
      been previously obtained.

            7.    ASSUMPTION BY ASSIGNEE.  Assignee hereby (i) accepts the
Assigned Interest and all rights of Assignor under the Partnership
Agreement in respect thereof and (ii) assumes (A) all of the liabilities of
the Partnership as they relate to the Assigned Interest accruing on or
after the date of this Assignment and (B) all obligations of Assignor under
the Partnership Agreement in respect of the Assigned Interest, and agrees
to be bound by the provisions thereof with respect thereto; provided,
however, that such assumption shall not be construed to convert any
nonrecourse liabilities to recourse liabilities nor shall it be construed
to revive any barred indebtedness or to waive any defense or limitation
with respect to any such liabilities.  In no event shall the liabilities
assumed by Assignee include any federal or state income tax liabilities of
Assignor relating to the Partnership or the Assigned Interest incurred or
accrued, whether known or unknown, as of the Effective Date.

            8.    NO BROKERS.  No broker, finder or similar intermediary
has acted for or on behalf of, or is entitled to any broker's, finder's or
similar fee or other commission from, Assignor or Assignee or any of their
respective Affiliates in connection with this Assignment or the
transactions contemplated hereby.  Assignor agrees to indemnify and hold
Assignee free and harmless, and Assignee agrees to indemnify and hold
Assignor free and harmless, from and against any and all claims, demands,
suits, causes of action, controversies, liabilities, costs, expenses, and
losses, including, without limitation, reasonable attorneys' fees and
expenses, that the indemnified party may suffer as a result of any claims
made or suits brought by any broker, salesperson, agent or finder who
claims to have introduced or to have been retained by the indemnifying
party in connection with this transaction.

            9.    FURTHER ASSURANCES.  Each party, at its sole cost and
expense, upon request of the other party, shall execute and deliver such
further instruments and do or cause to be done such further acts as may be
necessary to be done by such party to effectuate and confirm the assignment
of the Assigned Interest and the other matters set forth herein.  Without
limiting the foregoing, Assignor agrees to deliver to Assignee on the
Effective Date any Partnership property in its control or possession,
including any original copies of insurance policies.

            10.   MUTUAL RELEASE.

            (a)   As of the Effective Date, except as explicitly provided
      in this Assignment or except where such liabilities arise from or are
      caused by the gross negligence, willful misconduct or fraud of
      Assignee or its Affiliates, as the case may be, Assignor, on its
      behalf and on behalf of each of its Affiliates and each of their
      respective representatives, agents, successors, assigns, officers,
      directors, members, managers, employees and each of them
      (collectively, the "Assignor Parties") hereby irrevocably waives,
      releases and discharges, absolutely and forever, Assignee, the
      Partnership and each of their Affiliates from any and all liabilities
      to Assignor or the other Assignor Parties of any kind and nature
      whatsoever (including in respect of any rights of contribution or
      indemnification) in respect of facts, events, circumstances or
      conditions occurring or arising prior to the Effective Date.

            (b)   As of the Effective Date, except as explicitly provided
      in this Assignment or except where such liabilities arise from or are
      caused by the gross negligence, willful misconduct or fraud of
      Assignor or its Affiliates, as the case may be, Assignee, on its
      behalf and on behalf of each of its Affiliates and each of their
      respective representatives, agents, successors, assigns, officers,
      directors, members, managers, employees and each of them
      (collectively, the "Assignee Parties") hereby irrevocably waives,
      releases and discharges, absolutely and forever, the Assignor and
      each of its Affiliates, from any and all liabilities to Assignee, the
      Partnership, or the other Assignee Parties of any kind and nature
      whatsoever (including in respect of any rights of contribution or
      indemnification) in respect of facts, events, circumstances or
      conditions occurring or arising prior to the Effective Date.

            (c)   Notwithstanding anything to the contrary in paragraphs
      (a) and (b) above, nothing in this Section 10 shall be construed as a
      waiver or release by or in favor of either party with respect to any
      rights either of them may have pursuant to this Assignment.

            11.   Indemnification.

            (a)   Assignee hereby agrees to indemnify and hold Assignor
      free and harmless from and against any and all actions, causes of
      action, or suits brought against it by third parties (each, a "Third
      Party Claim") for losses, liabilities, damages and expenses,
      including, without limitation, reasonable attorneys' fees and
      disbursements (collectively, "Damages") arising from any such Third
      Party Claim, incurred by Assignor as a result of or relating to
      Assignor's status as a limited partner of the Partnership, except to
      the extent such Damages are caused by the gross negligence, willful
      misconduct or fraud of Assignor.

            (b)   Assignor shall give notice as promptly as practicable to
      Assignee of the assertion of any Third Party Claim; PROVIDED, that
      the failure of Assignor to give notice shall not relieve Assignee of
      its obligations under this Section 11 except to the extent (if any)
      that Assignee shall have been prejudiced thereby.  Assignee may, at
      its election and own expense, upon notice to Assignor, assume the
      defense thereof.  If Assignee assumes such defense, Assignor shall
      have the right (but not the obligation) to participate in the defense
      thereof and to employ counsel, at its own expense, separate from the
      counsel employed by Assignee.  Whether or not Assignee chooses to
      defend or prosecute any such Third Party Claim, each of the parties
      hereto shall cooperate in the defense or prosecution thereof.

Internal Revenue Service.  Assignor and Assignee shall each file all
required federal, state and local income tax returns and related returns

required by law.

hereby.

            15.   MODIFICATION AND WAIVER.  No supplement, modification,
waiver or termination of this Assignment or any provision hereof shall be
binding unless executed in writing by the parties to be bound thereby.  No
waiver of any of the provisions of this Assignment shall constitute a
waiver of any other provision (whether or not similar), nor shall such
waiver constitute a continuing waiver unless otherwise expressly provided.

            16.   GOVERNING LAW.  This Assignment shall be construed and
enforced in accordance with the laws of the State of Delaware applicable to

PERFORMANCE OF ANY OF THE OBLIGATIONS OF AMLI RESIDENTIAL PROPERTIES TRUST,
ASSIGNEE OR THE PARTNERSHIP.  NOTHING CONTAINED ABOVE SHALL LIMIT THE
REMEDIES AGAINST ANY PERSON FOR SUCH PERSON'S FRAUD OR INTENTIONAL
MISCONDUCT, IN WHICH EVENT SUCH REMEDIES SHALL BE DETERMINED BY APPLICABLE
LAW.

convenience and ease of reference only and shall not be considered in the
construction or interpretation of any provision of this Assignment.

            20.   SEVERABILITY.  If any provisions of this Assignment shall
be held by a court of competent jurisdiction to be contrary to law or
public policy, or otherwise unenforceable, the remaining provisions shall
remain in full force and effect and a court of competent jurisdiction shall
supply a provision or provisions to replace the affected provision(s) which

  (1) This amount reflects the Assignor's pro rata portion of the
      Partnership's estimated real estate taxes for all periods prior to
      the Effective Date and which the Partnership has not yet paid as of
      the Effective Date.  Because the Partnership makes distributions to
      its partners on a cash basis, this amount reflects the excess
      distributions received by Assignor from the Partnership as a result
      of non-payment of the taxes.  The Purchase Price is, therefore,
      reduced by this amount.  A final proration of the real estate taxes
      will be completed in accordance with Section 4 of the Assignment upon
      receipt by the Partnership of the final tax bill.
