following the grant of the Option.

(c) To the extent that the aggregate Fair Market Value of stock with
respect to which "incentive stock options" (within the meaning of Section 422 of
the Code, but without regard to Section 422(d) of the Code) are exercisable for
the first time by an Optionee during any calendar year (under the Plan and all
other incentive stock option plans of the Company and any parent or subsidiary
corporation (within the meaning of Section 422 of the Code) of the Company)
exceeds $100,000, such Options shall be treated as Non-Qualified Options to the
extent required by Section 422 of the Code. The rule set forth in the preceding
sentence shall be applied by taking Options into account in the order in which
they were granted. For purposes of this Section 4.4(c), the Fair Market Value of
stock shall be determined as of the time the Option with respect to such stock
is granted.

4.5. Consideration. In consideration of the granting of an Option,
the Optionee shall agree, in the written Stock Option Agreement, to remain in
the employ of (or to consult for or to serve as an Independent Director of, as
applicable) the Company, a Company Subsidiary, the Partnership or a Partnership
Subsidiary for a period of at least one year (or such shorter period as may be
fixed in the Stock Option Agreement or by action of the Committee following
grant of the Option) after the Option is granted (or, in the case of an
Independent Director, until the next annual meeting of stockholders of the
Company). Nothing in this Plan or in any Stock Option Agreement hereunder shall
(i) confer upon any Optionee any right to (a) continue in the employ of, or as a
consultant for, the Company, a Company Subsidiary, the Partnership or a
Partnership Subsidiary, or as a Director, or (b) receive any severance pay from
the Company, a Company Subsidiary, the Partnership or a Partnership Subsidiary
or (ii) interfere with or restrict in any way the rights of the Company, a
Company Subsidiary, the Partnership or a Partnership Subsidiary, which are
hereby expressly reserved, to discharge any Optionee at any time for any reason
whatsoever, with or without Cause.

ARTICLE V.
EXERCISE OF OPTIONS

5.1. Partial Exercise. An exercisable Option may be exercised in
whole or in part. However, an Option shall not be exercisable with respect to
fractional shares and the Committee (or the Board, in the case of Options
granted to Independent Directors) may require that, by the terms of the Option,
a partial exercise be with respect to a minimum number of shares.

5.2. Manner of Exercise. All or a portion of an exercisable
Option shall be deemed exercised upon delivery of all of the following to the
Secretary of the Company (or such other officer as identified in the
applicable Stock Option Agreement):


12
(a) A written notice complying with the applicable rules established
by the Committee (or the Board, in the case of Options granted to Independent
Directors) stating that the Option, or a portion thereof, is exercised. The
notice shall be signed by the Optionee or other person then entitled to exercise
the Option or such portion of the Option;

(b) Such representations and documents as the Committee (or the
Board, in the case of Options granted to Independent Directors), in its absolute
discretion, deems necessary or advisable to effect compliance with all
applicable provisions of the Securities Act of 1933, as amended, and any other
federal or state securities laws or regulations. The Committee or Board may, in
its absolute discretion, also take whatever additional actions it deems
appropriate to effect such compliance including, without limitation, placing
legends on share certificates and issuing stop-transfer notices to agents and
registrars;

(c) In the event that the Option shall be exercised pursuant to
Section 10.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option; and

(d) Full cash payment to the Secretary of the Company for the shares
with respect to which the Option, or portion thereof, is exercised. However, the
Committee (or the Board, in the case of Options granted to Independent
Directors), may in its discretion (i) allow a delay in payment up to thirty (30)
days from the date the Option, or portion thereof, is exercised; (ii) allow
payment, in whole or in part, through the delivery of shares of Common Stock
owned by the Optionee, duly endorsed for transfer to the Company with a Fair
Market Value on the date of delivery equal to the aggregate exercise price of
the Option or exercised portion thereof; (iii) allow payment, in whole or in
part, through the surrender of shares of Common Stock then issuable upon
exercise of the Option having a Fair Market Value on the date of Option exercise
equal to the aggregate exercise price of the Option or exercised portion
thereof; (iv) allow payment, in whole or in part, through the delivery of a full
recourse promissory note bearing interest (at no less than such rate as shall
then preclude the imputation of interest under the Code) and payable upon such
terms as may be prescribed by the Committee or the Board; or (v) allow payment
through any combination of the consideration provided in the foregoing
subparagraphs (ii), (iii) and (iv). In the case of a promissory note, the
Committee (or the Board, in the case of Options granted to Independent
Directors) may also prescribe the form of such note and the security to be given
for such note. The Option may not be exercised, however, by delivery of a
promissory note or by a loan from the Company when or where such loan or other
extension of credit is prohibited by law.

5.3. Transfer of Shares to a Company Employee, Consultant or
Independent Director. As soon as practicable after receipt by the Company,
pursuant to Section 5.2(d), of payment for the shares with respect to which an
Option (which in the case of a Company Employee, consultant or Independent
Director was issued to and is held by such Optionee in such capacity), or
portion thereof, is exercised by an Optionee who is a Company Employee,
Independent Director or a consultant to the Company, with respect to each such
exercise, the Company shall transfer to the Optionee the number of shares equal
to


13
(a) The amount of the payment made by the Optionee to the Company
pursuant to Section 5.2(d), divided by

(b) The price per share of the shares subject to the Option as
determined pursuant to Section 4.2.

5.4. Transfer of Shares to a Partnership Employee, Consultant or
Independent Director. (a) At the time that an Optionee who is an Employee,
Independent Director or consultant of the Partnership or a Partnership
Subsidiary exercises all or any part of an Option pursuant to the terms of this
Plan, such Optionee shall remit to the Partnership or the Partnership
Subsidiary, as the case may be, an amount equal to the product of the exercise
price per share of such Option and the number of shares with respect to such
Option being exercised by such Optionee.

(b) As soon as practicable after receipt by the Operating
Partnership of a notice of the exercise of shares with respect to which an
Option (which was issued to and is held by a Partnership Employee, consultant or
Independent Director in such capacity), or portion thereof, is exercised by an
Optionee who is a Partnership Employee, Independent Director or consultant, with
respect to each such exercise the Company shall sell to the Partnership, or the
Partnership Subsidiary in the case of an Optionee who is an Employee, consultant
or Independent Director of Partnership Subsidiary, the number of shares (the
"Partnership Purchased Shares") equal to the number of shares subject to such
exercise by such Optionee at a purchase price equal to the Fair Market Value of
a share of Common Stock at the time of the exercise (the "Partnership Purchase
Price");

(c) As soon as practicable after receipt of the Partnership
Purchased Shares by the Partnership, or the Partnership Subsidiary in the case
of an Optionee who is an Employee, Independent Director or consultant of a
Partnership Subsidiary, the Partnership or the Partnership Subsidiary, as the
case may be, shall transfer such shares to the Optionee at no additional cost.

5.5. Transfer of Payment to the Partnership. As soon as practicable
after receipt by the Company of the amount described in Section 5.2(d), 5.4(b)
and 5.5(b) the Company shall contribute to the Partnership an amount of cash
equal to such payment and the Partnership shall issue an additional interest in
the Partnership on the terms set forth in the Partnership Agreement.

5.6. Conditions to Issuance of Stock Certificates. The Company or
the Partnership shall not be required to issue or deliver any certificate or
certificates for shares of stock purchased upon the exercise of any Option or
portion thereof prior to fulfillment of all of the following conditions:

(a) The admission of such shares to listing on all stock exchanges
on which such class of stock is then listed;

(b) The completion of any registration or other qualification of
such shares under any state or federal law, or under the rulings or regulations
of the Securities and Exchange


14
Commission or any other governmental regulatory body which the Committee or
Board shall, in its absolute discretion, deem necessary or advisable;

(c) The obtaining of any approval or other clearance from any state
or federal governmental agency which the Committee (or Board, in the case of
Options granted to Independent Directors) shall, in its absolute discretion,
determine to be necessary or advisable;

(d) The lapse of such reasonable period of time following the
exercise of the Option as the Committee (or Board, in the case of Options
granted to Independent Directors) may establish from time to time for reasons of
administrative convenience; and

(e) The receipt by the Company or the Partnership of full payment
for such shares, including payment of any applicable withholding tax.

5.7. Rights as Stockholders. The holders of Options shall not be,
nor have any of the rights or privileges of, stockholders of the Company in
respect of any shares purchasable upon the exercise of any part of an Option
unless and until certificates representing such shares have been issued by the
Company to such holders.

5.8. Ownership and Transfer Restrictions. The Committee (or Board,
in the case of Options granted to Independent Directors), in its absolute
discretion, may impose such restrictions on the ownership and transferability of
the shares purchasable upon the exercise of an Option as it deems appropriate.
Any such restriction shall be set forth in the respective Stock Option Agreement
and may be referred to on the certificates evidencing such shares. The Committee
may require the Employee to give the Company prompt notice of any disposition of
shares of Common Stock acquired by exercise of an Incentive Stock Option within
(i) two years from the date of granting (including the date the Option is
modified, extended or renewed for purposes of Section 424(h) of the Code) such
Option to such Employee or (ii) one year after the transfer of such shares to
such Employee. The Committee may direct that the certificates evidencing shares
acquired by exercise of an Option refer to such requirement to give prompt
notice of disposition.

5.9. Limitations on Exercise of Options Granted to an Optionee. The
Committee (or the Board, in the case of Options granted to Independent
Directors), in its absolute discretion, may impose such limitations and
restrictions on the exercise of Options as it deems appropriate. Any such
limitation shall be set forth in the respective Stock Option Agreement.
Notwithstanding the foregoing, an Option is not exercisable if in the sole and
absolute discretion of the Committee the exercise of such Option would likely
result in any of the following:

(a) the Optionee's or any other person's ownership of capital stock
being in violation of the Stock Ownership Limit (as defined in the Company's
Articles of Incorporation); or

(b) income to the Company that could impair the Company's status as
a real estate investment trust, within the meaning of Sections 856 through 860
of the Code.


15
ARTICLE VI.
AWARD OF RESTRICTED STOCK

6.1. Eligibility. Subject to the Award Limit, Restricted Stock may
be awarded to any Employee who the Committee determines is a key Employee or any
Director or consultant whom the Committee determines should receive such an
award.

6.2. Award of Restricted Stock

(a) The Committee may from time to time, in its absolute discretion:

(i) Determine which Employees are key Employees and select
from among the key Employees, Directors or consultants (including
Employees, Directors or consultants who have previously received other
awards under this Plan) such of them as in its opinion should be awarded
Restricted Stock; and

(ii) Determine the purchase price, if any, and other terms and
conditions (including, without limitation, in the case of awards to
Employees, consultants or Independent Directors of the Partnership or any
Partnership Subsidiary, the mechanism for the transfer of the Restricted
Stock and payment therefor and, in the case of the repurchase of shares of
Restricted Stock subject to restrictions in effect at the time of the
Termination of Employment, Directorship or Consultancy of such Employee,
Director or consultant, as the case may be) applicable to such Restricted
Stock, consistent with this Plan.

(b) The Committee shall establish the purchase price, if any, and
form of payment for Restricted Stock; provided, however, that such purchase
price shall be no less than the par value of the Common Stock to be purchased,
unless otherwise permitted by applicable state law. In all cases, legal
consideration shall be required for each issuance of Restricted Stock.

(c) Upon the selection of a key Employee or consultant to be awarded
Restricted Stock, the Committee shall instruct the Secretary of the Company to
issue such Restricted Stock and may impose such conditions on the issuance of
such Restricted Stock as it deems appropriate.

6.3. Restricted Stock Agreement. Restricted Stock shall be issued
only pursuant to a written Restricted Stock Agreement, which shall be executed
by the selected key Employee or consultant and an authorized officer of the
Company and which shall contain such terms and conditions as the Committee shall
determine, consistent with this Plan.

6.4. Consideration. As consideration for the issuance of Restricted
Stock, in addition to payment of any purchase price, the Restricted Stockholder
shall agree, in the written Restricted Stock Agreement, to remain in the employ
of, or to consult for, the Company, a Company Subsidiary, the Partnership or a
Partnership Subsidiary for a period of at least one year after the Restricted
Stock is issued (or such shorter period as may be fixed in the Restricted Stock
Agreement or by action of the Committee following grant of the Restricted Stock)
or, in the case


16
of a Director, complete the remainder of such Director's elected term. Nothing
in this Plan or in any Restricted Stock Agreement hereunder shall (i) confer on
any Restricted Stockholder any right to (a) continue in the employ of, as a
Director of or as a consultant for, the Company, a Company Subsidiary, the
Partnership or a Partnership Subsidiary or (b) receive any severance pay from
the Company, a Company Subsidiary, the Partnership or a Partnership Subsidiary
or (ii) interfere with or restrict in any way the rights of the Company, a
Company Subsidiary, the Partnership or a Partnership Subsidiary, which are
hereby expressly reserved, to discharge the Employee or consultant at any time
for any reason whatsoever, with or without Cause, or any Director pursuant to
the Company's bylaws.

6.5. Rights as Stockholders. Subject to Section 6.6, upon delivery
of the shares of Restricted Stock to the escrow holder pursuant to Section 6.8,
the Restricted Stockholder shall have, unless otherwise provided by the
Committee, all the rights of a stockholder with respect to said shares, subject
to the restrictions in his Restricted Stock Agreement, including the right to
receive all dividends and other distributions paid or made with respect to the
shares; provided, however, that in the discretion of the Committee, any
extraordinary distributions with respect to the Common Stock shall be subject to
the restrictions set forth in Section 6.6.

6.6. Restriction. All shares of Restricted Stock issued under this
Plan (including any shares received by holders thereof with respect to shares of
Restricted Stock as a result of stock dividends, stock splits or any other form
of recapitalization) shall, in the terms of each individual Restricted Stock
Agreement, be subject to such restrictions as the Committee shall provide, which
restrictions may include, without limitation, restrictions concerning voting
rights and transferability and restrictions based on duration of employment with
the Company, Company performance and individual performance; provided, however,
that, unless the Committee otherwise provides in the terms of the Restricted
Stock Agreement or otherwise, no share of Restricted Stock granted to a person
subject to Section 16 of the Exchange Act shall be sold, assigned or otherwise
transferred until at least six months and one day have elapsed from the date on
which the Restricted Stock was issued, and provided, further, that, except with
respect to shares of Restricted Stock granted pursuant to Section 6.10, by
action taken after the Restricted Stock is issued, the Committee may, on such
terms and conditions as it may determine to be appropriate, remove any or all of
the restrictions imposed by the terms of the Restricted Stock Agreement.
Restricted Stock may not be sold or encumbered until all restrictions are
terminated or expire. If no consideration was paid by the Restricted Stockholder
upon issuance, a Restricted Stockholder's rights in unvested Restricted Stock
shall lapse upon a Termination of Employment or, if applicable, upon a
Termination of Directorship or a Termination of Consultancy; provided, however,
that the Committee in its sole and absolute discretion may provide that such
rights shall not lapse in the event of a Termination of Employment or
Termination of Directorship following a "change of ownership control" (within
the meaning of Treasury Regulation Section 1.62-27(e)(2)(v) or any successor
regulation thereto) of the Company or because of the Restricted Stockholder's
death or disability.

6.7. Repurchase of Restricted Stock. The Committee shall provide in
the terms of each individual Restricted Stock Agreement that the Company shall
have the right to repurchase from the Restricted Stockholder the Restricted
Stock then subject to restrictions under


17
the Restricted Stock Agreement immediately upon a Termination of Employment or,
if applicable, upon a Termination of Directorship or a Termination of
Consultancy, at a cash price per share equal to the price paid by the Restricted
Stockholder for such Restricted Stock; provided, however, that the Committee in
its sole and absolute discretion may provide that no such right of repurchase
shall exist in the event of a Termination of Employment, Termination of
Directorship or Termination of Consultancy following a "change of ownership or
control" (within the meaning of Treasury Regulation Section 1.162-27(e)(2)(v) or
any successor regulation thereto) of the Company or because of the Restricted
Stockholder's death or disability; provided, further, that, except with respect
to shares of Restricted Stock granted pursuant to Section 6.10, the Committee in
its sole and absolute discretion may provide that no such right of repurchase
shall exist in the event of a Termination of Employment, Termination of
Directorship or a Termination of Consultancy without Cause, following any change
in control or ownership of the Company, because of the Restricted Stockholder's
retirement, or otherwise.

6.8. Escrow. The Secretary of the Company or such other escrow
holder as the Committee may appoint shall retain physical custody of each
certificate representing Restricted Stock until all of the restrictions imposed
under the Restricted Stock Agreement with respect to the shares evidenced by
such certificate expire or shall have been removed.

6.9. Legend. In order to enforce the restrictions imposed upon
shares of Restricted Stock hereunder, the Committee shall cause a legend or
legends to be placed on certificates representing all shares of Restricted Stock
that are still subject to restrictions under Restricted Stock Agreements, which
legend or legends shall make appropriate reference to the conditions imposed
thereby.

6.10. Provisions Applicable to Section 162(m) Participants.

(a) Notwithstanding anything in the Plan to the contrary, the
Committee may grant Restricted Stock to a Section 162(m) Participant the
restrictions with respect to which lapse upon the attainment of performance
goals for the Company which are related to one or more of the following business
criteria: (i) pre-tax income, (ii) operating income, (iii) cash flow, (iv)
earnings per share, (v) return on equity, (vi) return on invested capital or
assets, (vii) cost reductions or savings, (viii) funds from operations, (ix)
appreciation in the fair market value of Common Stock and (x) earnings before
any one or more of the following items: interest, taxes, depreciation or
amortization.

(b) To the extent necessary to comply with the performance-based
compensation requirements of Section 162(m)(4)(C) of the Code, with respect to
Restricted Stock which may be granted to one or more Section 162(m)
Participants, no later than ninety (90) days following the commencement of any
fiscal year in question or any other designated fiscal period or period of
service (or such other time as may be required or permitted by Section 162(m) of
the Code), the Committee shall, in writing, (i) designate one or more Section
162(m) Participants, (ii) select the performance goal or goals applicable to the
fiscal year or other designated fiscal period or period of service, (iii)
establish the various targets and amounts of Restricted Stock which may be
earned for such fiscal year or other designated fiscal period or


18
period of service and (iv) specify the relationship between performance goals
and targets and the amounts of Restricted Stock to be earned by each Section
162(m) Participant for such fiscal year or other designated fiscal period or
period of service. Following the completion of each fiscal year or other
designated fiscal period or period of service, the Committee shall certify in
writing whether the applicable performance targets have been achieved for such
fiscal year or other designated fiscal period or period of service. In
determining the amount earned by a Section 162(m) Participant, the Committee
shall have the right to reduce (but not to increase) the amount payable at a
given level of performance to take into account additional factors that the
Committee may deem relevant to the assessment of individual or corporate
performance for the fiscal year or other designated fiscal period or period of
service.

ARTICLE VII.

PERFORMANCE AWARDS, DIVIDEND EQUIVALENTS,
DEFERRED STOCK, STOCK PAYMENTS

7.1. Eligibility. Subject to the Award Limit, one or more
Performance Awards, Dividend Equivalents, awards of Deferred Stock, and/or Stock
Payments may be granted to any Employee whom the Committee determines is a key
Employee or any consultant or Independent Director whom the Committee determines
should receive such an award.

7.2. Performance Awards. Any key Employee, consultant or Independent
Director selected by the Committee may be granted one or more Performance
Awards. The value of such Performance Awards may be linked to the market value,
book value, net profits or other measure of the value of Common Stock or other
specific performance criteria determined appropriate by the Committee, in each
case on a specified date or dates or over any period or periods determined by
the Committee, or may be based upon the appreciation in the market value, book
value, net profits or other measure of the value of a specified number of shares
of Common Stock over a fixed period or periods determined by the Committee. In
making such determinations, the Committee shall consider (among such other
factors as it deems relevant in light of the specific type of award) the
contributions, responsibilities and other compensation of the particular key
Employee or consultant.

7.3. Dividend Equivalents. Any key Employee, consultant or
Independent Director selected by the Committee may be granted Dividend
Equivalents based on the dividends declared on Common Stock, to be credited as
of dividend payment dates, during the period between the date an Option, Stock
Appreciation Right, Deferred Stock or Performance Award is granted, and the date
such Option, Stock Appreciation Right, Deferred Stock or Performance Award is
exercised, vests or expires, as determined by the Committee. Such Dividend
Equivalents shall be converted to cash or additional shares of Common Stock by
such formula and at such time and subject to such limitations as may be
determined by the Committee. With respect to Dividend Equivalents granted with
respect to Options intended to be qualified performance-based compensation for
purposes of Section 162(m) of the Code, such Dividend Equivalents shall be
payable regardless of whether such Option is exercised.


19
7.4. Stock Payments. Any key Employee, consultant or Independent
Director selected by the Committee may receive Stock Payments in the manner
determined from time to time by the Committee. The number of shares shall be
determined by the Committee and may be based upon the Fair Market Value, book
value, net profits or other measure of the value of Common Stock or other
specific performance criteria determined appropriate by the Committee,
determined on the date such Stock Payment is made or on any date thereafter.

7.5. Deferred Stock. Any key Employee, consultant or Independent
Director selected by the Committee may be granted an award of Deferred Stock in
the manner determined from time to time by the Committee. The number of shares
of Deferred Stock shall be determined by the Committee and may be linked to the
market value, book value, net profits or other measure of the value of Common
Stock or other specific performance criteria determined to be appropriate by the
Committee, in each case on a specified date or dates or over any period or
periods determined by the Committee. Common Stock underlying a Deferred Stock
award will not be issued until the Deferred Stock award has vested, pursuant to
a vesting schedule or performance criteria set by the Committee. Unless
otherwise provided by the Committee, a Grantee of Deferred Stock shall have no
rights as a Company stockholder with respect to such Deferred Stock until such
time as the award has vested and the Common Stock underlying the award has been
issued.

7.6. Performance Award Agreement, Dividend Equivalent Agreement,
Deferred Stock Agreement, Stock Payment Agreement. Each Performance Award,
Dividend Equivalent, award of Deferred Stock and/or Stock Payment shall be
evidenced by a written agreement, which shall be executed by the Grantee and an
authorized Officer of the Company and which shall contain such terms and
conditions (including, without limitation, in the case of awards to Employees,
consultants or Independent Directors of the Partnership or any Partnership
Subsidiary, the mechanism for the transfer or rights under such awards) as the
Committee shall determine, consistent with this Plan.

7.7. Term. The term of a Performance Award, Dividend Equivalent,
award of Deferred Stock and/or Stock Payment shall be set by the Committee in
its discretion.

7.8. Exercise or Purchase Price. The Committee may establish the
exercise or purchase price of a Performance Award, shares of Deferred Stock, or
shares received as a Stock Payment; provided, however, that such price shall not
be less than the par value for a share of Common Stock, unless otherwise
permitted by applicable state law.

7.9. Exercise Upon Termination of Employment. A Performance Award,
Dividend Equivalent, award of Deferred Stock and/or Stock Payment is exercisable
or payable only while the Grantee is an Employee or consultant; provided,
however, that the Committee in its sole and absolute discretion may provide that
the Performance Award, Dividend Equivalent, award of Deferred Stock and/or Stock
Payment may be exercised or paid subsequent to a Termination of Employment
following a "change of control or ownership" (within the meaning of Section
1.162-27(e)(2)(v) or any successor regulation thereto) of the Company; provided,
further, that except with respect to Performance Awards granted pursuant to
Section 7.12, the


20
Committee in its sole and absolute discretion may provide that the Performance
Awards may be exercised or paid following a Termination of Employment or a
Termination of Consultancy without cause, or following a change in control of
the Company, or because of the Grantee's retirement, death or disability, or
otherwise.

7.10. Payment on Exercise. Payment of the amount determined under
Section 7.1 or 7.2 above shall be in cash, in Common Stock or a combination of
both, as determined by the Committee. To the extent any payment under this
Article VII is effected in Common Stock, it shall be made subject to
satisfaction of all provisions of Section 5.3.

7.11. Consideration. In consideration of the granting of a
Performance Award, Dividend Equivalent, award of Deferred Stock and/or Stock
Payment, the Grantee shall agree, in a written agreement, to remain in the
employ of, or to consult for, the Company, a Company Subsidiary, the Partnership
or a Partnership Subsidiary for a period of at least one year after such
Performance Award, Dividend Equivalent, award of Deferred Stock and/or Stock
Payment is granted (or such shorter period as may be fixed in such agreement or
by action of the Committee following such grant). Nothing in this Plan or in any
agreement hereunder shall (i) confer on any Grantee any right to (a) continue in
the employ of, or as a consultant for, the Company, a Company Subsidiary, the
Partnership or a Partnership Subsidiary or (b) receive any severance pay from
the Company, a Company Subsidiary, the Partnership or a Partnership Subsidiary
or (ii) interfere with or restrict in any way the rights of the Company, a
Company Subsidiary, the Partnership or a Partnership Subsidiary, which are
hereby expressly reserved, to discharge any Grantee at any time for any reason
whatsoever, with or without Cause.

7.12. Provisions Applicable to Section 162(m) Participants.

(a) Notwithstanding anything in the Plan to the contrary, the
Committee may grant any performance or incentive awards described in Article VII
to a Section 162(m) Participant that vest or become exercisable or payable upon
the attainment of performance goals for the Company which are related to one or
more of the following business criteria: (i) pre-tax income, (ii) operating
income, (iii) cash flow, (iv) earnings per share, (v) return on equity, (vi)
return on invested capital or assets, (vii) cost reductions or savings, (viii)
funds from operations, (ix) appreciation in the fair market value of Common
Stock and (x) earnings before any one or more of the following items: interest,
taxes, depreciation or amortization.

(b) To the extent necessary to comply with the performance-based
compensation requirements of Section 162(m)(4)(C) of the Code, with respect to
performance or incentive awards described in Article VII which may be granted to
one or more Section 162(m) Participants, no later than ninety (90) days
following the commencement of any fiscal year in question or any other
designated fiscal period or period of service (or such other time as may be
required or permitted by Section 162(m) of the Code), the Committee shall, in
writing, (i) designate one or more Section 162(m) Participants, (ii) select the
performance goal or goals applicable to the fiscal year or other designated
fiscal period or period of service, (iii) establish the various targets and
bonus amounts which may be earned for such fiscal year or other designated
fiscal period or period of service and (iv) specify the relationship between


21
performance goals and targets and the amounts to be earned by each Section
162(m) Participant for such fiscal year or other designated fiscal period or
period of service. Following the completion of each fiscal year or other
designated fiscal period or period of service, the Committee shall certify in
writing whether the applicable performance targets have been achieved for such
fiscal year or other designated fiscal period or period of service. In
determining the amount earned by a Section 162(m) Participant, the Committee
shall have the right to reduce (but not to increase) the amount payable at a
given level of performance to take into account additional factors that the
Committee may deem relevant to the assessment of individual or corporate
performance for the fiscal year or other designated fiscal period or period of
service.

ARTICLE VIII.
STOCK APPRECIATION RIGHTS

8.1. Grant of Stock Appreciation Rights. A Stock Appreciation Right
may be granted to any key Employee or consultant selected by the Committee. A
Stock Appreciation Right may be granted (i) in connection and simultaneously
with the grant of an Option, (ii) with respect to a previously granted Option,
or (iii) independent of an Option. A Stock Appreciation Right shall be subject
to such terms and conditions (including, without limitation, the mechanism for
the transfer of rights under such awards) not inconsistent with this Plan as the
Committee shall impose and shall be evidenced by a written Stock Appreciation
Right Agreement, which shall be executed by the Grantee and an authorized
officer of the Company. The Committee, in its discretion, may determine whether
a Stock Appreciation Right is to qualify as performance-based compensation as
described in Section 162(m)(4)(C) of the Code and Stock Appreciation Right
Agreements evidencing Stock Appreciation Rights intended to so qualify shall
contain such terms and conditions as may be necessary to meet the applicable
provisions of Section 162(m) of the Code.

8.2. Coupled Stock Appreciation Rights

(a) A Coupled Stock Appreciation Right ("CSAR") shall be related to
a particular Option and shall be exercisable only when and to the extent the
related Option is exercisable.

(b) A CSAR may be granted to the Grantee for no more than the number
of shares subject to the simultaneously or previously granted Option to which it
is coupled.

(c) A CSAR shall entitle the Grantee (or other person entitled to
exercise the Option pursuant to this Plan) to surrender to the Company
unexercised a portion of the Option to which the CSAR relates (to the extent
then exercisable pursuant to its terms) and to receive from the Company in
exchange therefor an amount determined by multiplying the difference obtained by
subtracting the Option exercise price from the Fair Market Value of a share of
Common Stock on the date of exercise of the CSAR by the number of shares of
Common Stock with respect to which the CSAR shall have been exercised, subject
to any limitations the Committee may impose.

8.3. Independent Stock Appreciation Rights

(a) An Independent Stock Appreciation Right ("ISAR") shall be
unrelated to any Option and shall have a term set by the Committee. An ISAR
shall be exercisable in such installments as the Committee may determine. An
ISAR shall cover such number of shares of Common Stock as the Committee may
determine; provided, however, that unless the Committee otherwise provides in
the terms of the ISAR or otherwise, no ISAR granted to a person subject to
Section 16 of the Exchange Act shall be exercisable until at least six months
have elapsed from (but excluding) the date on which the Option was granted. The
exercise price per share of Common Stock subject to each ISAR shall be set by
the Committee. An ISAR is exercisable only while the Grantee is an Employee or
consultant; provided that the Committee may determine that the ISAR may be
exercised subsequent to Termination of Employment, Termination of Directorship
or Termination of Consultancy without cause, or following a change in control of
the Company, or because of the Grantee's retirement, death or disability, or
otherwise.

(b) An ISAR shall entitle the Grantee (or other person entitled to
exercise the ISAR pursuant to this Plan) to exercise all or a specified portion
of the ISAR (to the extent then exercisable pursuant to its terms) and to
receive from the Company an amount determined by multiplying the difference
obtained by subtracting the exercise price per share of the ISAR from the Fair
Market Value of a share of Common Stock on the date of exercise of the ISAR by
the number of shares of Common Stock with respect to which the ISAR shall have
been exercised, subject to any limitations the Committee may impose.

8.4. Payment and Limitations on Exercise

(a) Payment of the amount determined under Section 8.2(c) and 8.3(b)
above shall be in cash, in Common Stock (based on its Fair Market Value as of
the date the Stock Appreciation Right is exercised) or a combination of both, as
determined by the Committee. To the extent such payment is effected in Common
Stock it shall be made subject to satisfaction of all provisions of Section 5.3
above pertaining to Options.

(b) Grantees of Stock Appreciation Rights may be required to comply
with any timing or other restrictions with respect to the settlement or exercise
of a Stock Appreciation Right, including a window-period limitation, as may be
imposed in the discretion of the Board or Committee.

8.5. Consideration. In consideration of the granting of a Stock
Appreciation Right, the Grantee shall agree, in the written Stock Appreciation
Right Agreement, to remain in the employ of, or to consult for, the Company, a
Company Subsidiary, the Partnership or a Partnership Subsidiary for a period of
at least one year after the Stock Appreciation Right is granted (or such shorter
period as may be fixed in the Stock Appreciation Right Agreement or by action of
the Committee following grant of the Restricted Stock). Nothing in this Plan or
in any Stock Appreciation Right Agreement hereunder shall (i) confer on any
Grantee any right to (a) continue in the employ of, or as a consultant for, the
Company, a Company Subsidiary, the


23
Partnership or a Partnership Subsidiary or (b) receive any severance pay from
the Company, a Company Subsidiary, the Partnership or a Partnership Subsidiary
or (ii) interfere with or restrict in any way the rights of the Company, a
Company Subsidiary, the Partnership or a Partnership Subsidiary, which are
hereby expressly reserved, to discharge any Grantee at any time for any reason
whatsoever, with or without Cause.

ARTICLE IX.
ADMINISTRATION

9.1. Compensation Committee. Prior to the Company's initial
registration of Common Stock under Section 12 of the Exchange Act, the
Compensation Committee shall consist of the entire Board. Following such
registration, the Compensation Committee (or another committee or a subcommittee
of the Board assuming the functions of the Committee under this Plan) shall
consist solely of two or more Independent Directors appointed by and holding
office at the pleasure of the Board, each of whom is both a "non-employee
director" as defined by Rule 16b-3 and an "outside director" for purposes of
Section 162(m) of the Code. Appointment of Committee members shall be effective
upon acceptance of appointment. Committee members may resign at any time by
delivering written notice to the Board. Vacancies in the Committee may be filled
by the Board.

9.2. Duties and Powers of Committee. It shall be the duty of the
Committee to conduct the general administration of this Plan in accordance with
its provisions. The Committee shall have the power to interpret this Plan and
the agreements pursuant to which Options, awards of Restricted Stock or Deferred
Stock, Performance Awards, Stock Appreciation Rights, Dividend Equivalents or
Stock Payments are granted or awarded, and to adopt such rules for the
administration, interpretation, and application of this Plan as are consistent
therewith and to interpret, amend or revoke any such rules. Notwithstanding the
foregoing, the full Board, acting by a majority of its members in office, shall
conduct the general administration of the Plan with respect to Options granted
to Independent Directors. Any such grant or award under this Plan need not be
the same with respect to each Optionee, Grantee or Restricted Stockholder. Any
such interpretations and rules with respect to Incentive Stock Options shall be
consistent with the provisions of Section 422 of the Code. In its absolute
discretion, the Board may at any time and from time to time exercise any and all
rights and duties of the Committee under this Plan except with respect to
matters which under Rule 16b-3 or Section 162(m) of the Code, or any regulations
or rules issued thereunder, are required to be determined in the sole discretion
of the Committee.

9.3. Majority Rule; Unanimous Written Consent. The Committee shall
act by a majority of its members in attendance at a meeting at which a quorum is
present or by a memorandum or other written instrument signed by all members of
the Committee.

9.4. Compensation; Professional Assistance; Good Faith Actions.
Members of the Committee shall receive such compensation, if any, for their
services as members as may be determined by the Board. All expenses and
liabilities which members of the Committee incur in connection with the
administration of this Plan shall be borne by the Company. The Committee


24
may, with the approval of the Board, employ attorneys, consultants, accountants,
appraisers, brokers, or other persons. The Committee, the Company and the
Company's officers and Directors shall be entitled to rely upon the advice,
opinions or valuations of any such persons. All actions taken and all
interpretations and determinations made by the Committee or the Board in good
faith shall be final and binding upon all Optionees, Grantees, Restricted
Stockholders, the Company and all other interested persons. No members of the
Committee or Board shall be personally liable for any action, determination or
interpretation made in good faith with respect to this Plan, Options, awards of
Restricted Stock or Deferred Stock, Performance Awards, Stock Appreciation
Rights, Dividend Equivalents or Stock Payments, and all members of the Committee
and the Board shall be fully protected by the Company in respect of any such
action, determination or interpretation.

9.5. Delegation of Authority to Grant Awards. The Committee may, but
need not, delegate from time to time to a committee consisting of one or more
members of the Committee or of one or more officers of the Company some or all
of the Committee's authority to grant awards under this Plan to eligible
recipients; provided, however, that each such recipient must be an individual
other than an "officer," "director" or "beneficial owner of more than ten per
centum of any class of any equity security" within the meaning of each such term
as it is used under Section 16(b) of the Exchange Act. Any delegation hereunder
shall be subject to the restrictions and limits that the Committee specifies at
the time of such delegation of authority and may be rescinded at any time by the
Committee. At all times, any committee appointed under this Section 9.5 shall
serve in such capacity at the pleasure of the Committee.

ARTICLE X.
MISCELLANEOUS PROVISIONS

10.1. Not Transferable. Options, Restricted Stock awards, Deferred
Stock awards, Performance Awards, Stock Appreciation Rights, Dividend
Equivalents or Stock Payments under this Plan may not be sold, pledged,
assigned, or transferred in any manner other than by will or the laws of descent
and distribution, unless and until such rights or awards have been exercised, or
the shares underlying such rights or awards have been issued, and all
restrictions applicable to such shares have lapsed. No Option, Restricted Stock
award, Deferred Stock award, Performance Award, Stock Appreciation Right,
Dividend Equivalent or Stock Payment or interest or right therein shall be
liable for the debts, contracts or engagements of the Optionee, Grantee or
Restricted Stockholder or his successors in interest or shall be subject to
disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means whether such disposition be voluntary or
involuntary or by operation of law by judgment, levy, attachment, garnishment or
any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence.

During the lifetime of the Optionee or Grantee, only he may exercise
an Option or other right or award (or any portion thereof) granted to him under
the Plan. After the death of the Optionee or Grantee, any exercisable portion of
an Option or other right or award may, prior to the time when such portion
becomes unexercisable under the Plan or the applicable Stock Option


25
Agreement or other agreement, be exercised by his personal representative or by
any person empowered to do so under the deceased Optionee's or Grantee's will or
under the then applicable laws of descent and distribution.

10.2. Amendment, Suspension or Termination of this Plan. Except as
otherwise provided in this Section 10.2, this Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Board or the Committee. However, without approval of the
Company's stockholders given within twelve months before or after the action by
the Board or the Committee, no action of the Board or the Committee may, except
as provided in Section 10.3, increase the limits imposed in Section 2.1 on the
maximum number of shares which may be issued under this Plan or increase the
Award Limit, and no action of the Board or the Committee may be taken that would
otherwise require stockholder approval as a matter of applicable law, regulation
or rule. No amendment, suspension or termination of this Plan shall, without the
consent of the holder of Options, Restricted Stock awards, Deferred Stock
awards, Performance Awards, Stock Appreciation Rights, Dividend Equivalents or
Stock Payments, alter or impair any rights or obligations under any Options,
Restricted Stock awards, Deferred Stock awards, Performance Awards, Stock
Appreciation Rights, Dividend Equivalents or Stock Payments theretofore granted
or awarded, unless the award itself otherwise expressly so provides. No Options,
Restricted Stock, Deferred Stock, Performance Awards, Stock Appreciation Rights,
Dividend Equivalents or Stock Payments may be granted or awarded during any
period of suspension or after termination of this Plan, and in no event may any
Incentive Stock Option be granted under this Plan after the first to occur of
the following events:

(a) The expiration of ten years from the date the 1997 Stock Option
and Incentive Plan of AMB Property Corporation and AMB Investment Management,
Inc. and their Respective Subsidiaries was adopted by the Board; or

(b) The expiration of ten years from the date the 1997 Stock Option
and Incentive Plan of AMB Property Corporation and AMB Investment Management,
Inc. and their Respective Subsidiaries was approved by the Company's
stockholders under Section 10.4.

10.3. Changes in Common Stock or Assets of the Company, Acquisition
or Liquidation of the Company and Other Corporate Events.

(a) Subject to Section 10.3(d), in the event that the Committee (or
the Board, in the case of Options granted to Independent Directors) determines
that any dividend or other distribution (whether in the form of cash, Common
Stock, other securities, or other property), recapitalization, reclassification,
stock split, reverse stock split, reorganization, merger, consolidation,
split-up, spin-off, combination, repurchase, liquidation, dissolution, or sale,
transfer, exchange or other disposition of all or substantially all of the
assets of the Company (including, but not limited to, a Corporate Transaction),
or exchange of Common Stock or other securities of the Company, issuance of
warrants or other rights to purchase Common Stock or other securities of the
Company, or other similar corporate transaction or event, in the Committee's
sole discretion (or in the case of Options granted to Independent Directors, the


26
Board's sole discretion), affects the Common Stock such that an adjustment is
determined by the Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan or with respect to an Option, Restricted Stock award, Performance
Award, Stock Appreciation Right, Dividend Equivalent, Deferred Stock award or
Stock Payment, then the Committee (or the Board, in the case of Options granted
to Independent Directors) shall, in such manner as it may deem equitable, adjust
any or all of

(i) the number and kind of shares of Common Stock (or other
securities or property) with respect to which Options, Performance Awards,
Stock Appreciation Rights, Dividend Equivalents or Stock Payments may be
granted under the Plan, or which may be granted as Restricted Stock or
Deferred Stock (including, but not limited to, adjustments of the
limitations in Section 2.1 on the maximum number and kind of shares which
may be issued and adjustments of the Award Limit),

(ii) the number and kind of shares of Common Stock (or other
securities or property) subject to outstanding Options, Performance
Awards, Stock Appreciation Rights, Dividend Equivalents, or Stock
Payments, and in the number and kind of shares of outstanding Restricted
Stock or Deferred Stock, and

(iii) the grant or exercise price with respect to any Option,
Performance Award, Stock Appreciation Right, Dividend Equivalent or Stock
Payment.

(b) Subject to Section 10.3(d), in the event of any Corporate
Transaction or other transaction or event described in Section 10.3(a) or any
unusual or nonrecurring transactions or events affecting the Company, any
affiliate of the Company, or the financial statements of the Company or any
affiliate, or of changes in applicable laws, regulations, or accounting
principles, the Committee (or the Board, in the case of Options granted to
Independent Directors) in its discretion is hereby authorized to take any one or
more of the following actions whenever the Committee (or the Board, in the case
of Options granted to Independent Directors) determines that such action is
appropriate or desirable:

(i) In its sole and absolute discretion, and on such terms and
conditions as it deems appropriate, the Committee (or the Board, in the
case of Options granted to Independent Directors) may provide, either by
the terms of the agreement or by action taken prior to the occurrence of
such transaction or event and either automatically or upon the optionee's
request, for either the purchase of any such Option, Performance Award,
Stock Appreciation Right, Dividend Equivalent, or Stock Payment, or any
Restricted Stock or Deferred Stock for an amount of cash equal to the
amount that could have been attained upon the exercise of such option,
right or award or realization of the optionee's rights had such option,
right or award been currently exercisable or payable or fully vested or
the replacement of such option, right or award with other rights or
property selected by the Committee (or the Board, in the case of awards
granted to Independent Directors) in its sole discretion;


27
(ii) In its sole and absolute discretion, the Committee (or
the Board, in the case of awards granted to Independent Directors) may
provide, either by the terms of such Option, Performance Award, Stock
Appreciation Right, Dividend Equivalent, or Stock Payment, or Restricted
Stock or Deferred Stock or by action taken prior to the occurrence of such
transaction or event that it cannot vest, be exercised or become payable
after such event;

(iii) In its sole and absolute discretion, and on such terms
and conditions as it deems appropriate, the Committee (or the Board, in
the case of awards granted to Independent Directors) may provide, either
by the terms of such Option, Performance Award, Stock Appreciation Right,
Dividend Equivalent, or Stock Payment, or Restricted Stock or Deferred
Stock or by action taken prior to the occurrence of such transaction or
event, that for a specified period of time prior to such transaction or
event, such option, right or award shall be exercisable as to all shares
covered thereby, notwithstanding anything to the contrary in (i) Section
4.4 or (ii) the provisions of such Option, Performance Award, Stock
Appreciation Right, Dividend Equivalent, or Stock Payment, or Restricted
Stock or Deferred Stock;

(iv) In its sole and absolute discretion, and on such terms
and conditions as it deems appropriate, the Committee (or the Board, in
the case of awards granted to Independent Directors) may provide, either
by the terms of such Option, Performance Award, Stock Appreciation Right,
Dividend Equivalent, or Stock Payment, or Restricted Stock or Deferred
Stock or by action taken prior to the occurrence of such transaction or
event, that upon such event, such option, right or award be assumed by the
successor or survivor corporation, or a parent or subsidiary thereof, or
shall be substituted for by similar options, rights or awards covering the
stock of the successor or survivor corporation, or a parent or subsidiary
thereof, with appropriate adjustments as to the number and kind of shares
and prices;

(v) In its sole and absolute discretion, and on such terms and
conditions as it deems appropriate, the Committee (or the Board, in the
case of awards granted to Independent Directors) may make adjustments in
the number and type of shares of Common Stock (or other securities or
property) subject to outstanding Options, Performance Awards, Stock
Appreciation Rights, Dividend Equivalents, or Stock Payments, and in the
number and kind of outstanding Restricted Stock or Deferred Stock and/or
in the terms and conditions of, and the criteria included in, outstanding
options, rights and awards and options, rights and awards which may be
granted in the future; and

(vi) In its sole and absolute discretion, and on such terms
and conditions as it deems appropriate, the Committee may provide either
by the terms of a Restricted Stock award or Deferred Stock award or by
action taken prior to the occurrence of such event that, for a specified
period of time prior to such event, the restrictions imposed under a
Restricted Stock Agreement or a Deferred Stock Agreement upon some or all
shares of Restricted Stock or Deferred Stock may be terminated, and, in


28
the case of Restricted Stock, some or all shares of such Restricted Stock
may cease to be subject to repurchase under Section 6.6 or forfeiture
under Section 6.5 after such event.

(c) Subject to Section 10.3(d) and 10.8, the Committee (or the
Board, in the case of awards granted to Independent Directors) may, in its
discretion, include such further provisions and limitations in any Option,
Performance Award, Stock Appreciation Right, Dividend Equivalent, or Stock
Payment, or Restricted Stock or Deferred Stock agreement or certificate, as it
may deem equitable and in the best interests of the Company.

(d) With respect to Options, Restricted Stock, Deferred Stock, Stock
Appreciation Rights and performance or incentive awards described in Article VII
which are granted to Section 162(m) Participants and are intended to qualify as
performance-based compensation under Section 162(m)(4)(C), no adjustment or
action described in this Section 10.3 or in any other provision of the Plan
shall be authorized to the extent that such adjustment or action would cause the
Plan to violate Section 422(b)(1) of the Code or would cause such option or
stock appreciation right to fail to so qualify under Section 162(m)(4)(C), as
the case may be, or any successor provisions thereto. Furthermore, no such
adjustment or action shall be authorized to the extent such adjustment or action
would result in short-swing profits liability under Section 16 or violate the
exemptive conditions of Rule 16b-3 unless the Committee (or the Board, in the
case of awards granted to Independent Directors) determines that the option or
other award is not to comply with such exemptive conditions. The number of
shares of Common Stock subject to any option, right or award shall always be
rounded to the next whole number.

10.4. Approval of Plan by Stockholders. This Plan will be submitted
for the approval of the Company's stockholders within twelve months after the
date of the Board's initial adoption of this Plan. Options, Performance Awards,
Stock Appreciation Rights, Dividend Equivalents or Stock Payments may be granted
and Restricted Stock or Deferred Stock may be awarded prior to such stockholder
approval, provided that such Options, Performance Awards, Stock Appreciation
Rights, Dividend Equivalents or Stock Payments shall not be exercisable and such
Restricted Stock or Deferred Stock shall not vest prior to the time when this
Plan is approved by the stockholders, and provided further that if such approval
has not been obtained at the end of said twelve-month period, all Options,
Performance Awards, Stock Appreciation Rights, Dividend Equivalents or Stock
Payments previously granted and all Restricted Stock or Deferred Stock
previously awarded under this Plan shall thereupon be canceled and become null
and void.

10.5. Tax Withholding. The Company shall be entitled to require
payment in cash or deduction from other compensation payable to each Optionee,
Grantee or Restricted Stockholder of any sums required by federal, state or
local tax law to be withheld with respect to the issuance, vesting, exercise or
payment of any Option, Restricted Stock, Deferred Stock, Performance Award,
Stock Appreciation Right, Dividend Equivalent or Stock Payment. The Committee
(or the Board, in the case of awards granted to Independent Directors) may in
its discretion and in satisfaction of the foregoing requirement allow such
Optionee, Grantee or Restricted Stockholder to elect to have the Company
withhold shares of Common Stock


29
otherwise issuable under such Option or other award (or allow the return of
shares of Common Stock) having a Fair Market Value equal to the sums required to
be withheld.

10.6. Loans. The Committee may, in its discretion, extend one or
more loans to key Employees in connection with the exercise or receipt of an
Option, Performance Award, Stock Appreciation Right, Dividend Equivalent or
Stock Payment granted under this Plan, or the issuance of Restricted Stock or
Deferred Stock awarded under this Plan. The terms and conditions of any such
loan shall be set by the Committee.

10.7. Forfeiture Provisions. Pursuant to its general authority to
determine the terms and conditions applicable to awards under the Plan, the
Committee (or the Board, in the case of awards granted to Independent Directors)
shall have the right (to the extent consistent with the applicable exemptive
conditions of Rule 16b-3) to provide, in the terms of Options or other awards
made under the Plan, or to require the recipient to agree by separate written
instrument, that (i) any proceeds, gains or other economic benefit actually or
constructively received by the recipient upon any receipt or exercise of the
award, or upon the receipt or resale of any Common Stock underlying such award,
must be paid to the Company, and (ii) the award shall terminate and any
unexercised portion of such award (whether or not vested) shall be forfeited, if
(a) a Termination of Employment, Termination of Consultancy or Termination of
Directorship occurs prior to a specified date, or within a specified time period
following receipt or exercise of the award, or (b) the recipient at any time, or
during a specified time period, engages in any activity in competition with the
Company, or which is inimical, contrary or harmful to the interests of the
Company, as further defined by the Committee (or the Board, as applicable).

10.8. Limitations Applicable to Section 16 Persons and
Performance-Based Compensation. Notwithstanding any other provision of this
Plan, this Plan, and any Option, Performance Award, Stock Appreciation Right,
Dividend Equivalent or Stock Payment granted, or Restricted Stock or Deferred
Stock awarded, to any individual who is then subject to Section 16 of the
Exchange Act, shall be subject to any additional limitations set forth in any
applicable exemptive rule under Section 16 of the Exchange Act (including any
amendment to Rule 16b-3 of the Exchange Act) that are requirements for the
application of such exemptive rule. To the extent permitted by applicable law,
the Plan, Options, Performance Awards, Stock Appreciation Rights, Dividend
Equivalents, Stock Payments, Restricted Stock and Deferred Stock granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule. Furthermore, notwithstanding any other provision
of this Plan, any Option, Stock Appreciation Right or performance or incentive
award described in Article VII which is granted to a Section 162(m) Participant
and is intended to qualify as performance-based compensation as described in
Section 162(m)(4)(C) of the Code shall be subject to any additional limitations
set forth in Section 162(m) of the Code (including any amendment to Section
162(m) of the Code) or any regulations or rulings issued thereunder that are
requirements for qualification as performance-based compensation as described in
Section 162(m)(4)(C) of the Code, and this Plan shall be deemed amended to the
extent necessary to conform to such requirements.


30
10.9. Effect of Plan Upon Options and Compensation Plans. The
adoption of this Plan shall not affect any other compensation or incentive plans
in effect for the Company or any Subsidiary. Nothing in this Plan shall be
construed to limit the right of the Company (i) to establish any other forms of
incentives or compensation for Employees, Directors or Consultants of the
Company or any Subsidiary or (ii) to grant or assume options or other rights or
awards otherwise than under this Plan in connection with any proper corporate
purpose including but not by way of limitation, the grant or assumption of
options in connection with the acquisition by purchase, lease, merger,
consolidation or otherwise, of the business, stock or assets of any corporation,
partnership, limited liability company, firm or association.

10.10. Section 83(b) Election Prohibited. No Grantee, Optionee or
Restricted Stockholder may make an election under Section 83(b) of the Code with
respect to any award or grant under this Plan.

10.11. Compliance with Laws. This Plan, the granting and vesting of
Options, Restricted Stock awards, Deferred Stock awards, Performance Awards,
Stock Appreciation Rights, Dividend Equivalents or Stock Payments under this
Plan and the issuance and delivery of shares of Common Stock and the payment of
money under this Plan or under Options, Performance Awards, Stock Appreciation
Rights, Dividend Equivalents or Stock Payments granted or Restricted Stock or
Deferred Stock awarded hereunder are subject to compliance with all applicable
federal and state laws, rules and regulations (including but not limited to
state and federal securities law and federal margin requirements) and to such
approvals by any listing, regulatory or governmental authority as may, in the
opinion of counsel for the Company, be necessary or advisable in connection
therewith. Any securities delivered under this Plan shall be subject to such
restrictions, and the person acquiring such securities shall, if requested by
the Company, provide such assurances and representations to the Company as the
Company may deem necessary or desirable to assure compliance with all applicable
legal requirements. To the extent permitted by applicable law, the Plan,
Options, Restricted Stock awards, Deferred Stock awards, Performance Awards,
Stock Appreciation Rights, Dividend Equivalents or Stock Payments granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such laws, rules and regulations.

10.12. Titles. Titles are provided herein for convenience only and
are not to serve as a basis for interpretation or construction of this Plan.

10.13. Governing Law. This Plan and any agreements hereunder shall
be administered, interpreted and enforced under the internal laws of the State
of California without regard to conflicts of laws thereof.

10.14. Conflicts with Company's Articles of Incorporation.
Notwithstanding any other provision of this Plan, no Optionee, Grantee or
Restricted Stockholder shall acquire or have any right to acquire any Common
Stock, and shall not have other rights under this Plan, which are prohibited
under the Company's Articles of Incorporation.
