                            SIMON PROPERTY GROUP, L.P.
                            1998 STOCK INCENTIVE PLAN

                                    ARTICLE 1

                                     GENERAL

            1.1 Purpose.

            The purpose of this 1998 Stock Incentive Plan (the "Plan") is to
provide for certain key personnel (as defined in Section 1.3) of Simon Property
Group, L.P. (the "Partnership") and certain of its Affiliates (as defined in
Section 1.6) an equity-based incentive to maintain and enhance the performance
and profitability of the Partnership and Simon Property Group, Inc. (the
"Company"). It is intended that awards granted under this Plan may provide
performance-based compensation within the meaning of section 162(m) of the
Internal Revenue Code of 1986, as amended (the "Code"), to the extent
applicable.

            1.2 Administration.

            (a) The Plan shall be administered by a committee (the "Committee")
      appointed by the Partnership, by action of its General Partner(s), which
      Committee shall consist of two or more directors of the Company. A
      majority of the Committee shall constitute a quorum, and the acts of a
      majority of the members present at any meeting at which a quorum is
      present or acts approved in writing by all members of the Committee
      without a meeting, shall be acts of the Committee. The members of the
      Committee shall be appointed by and may be changed at any time and from
      time to time in the discretion of, the Partnership, by action of its
      General Partner(s).

            (b)The Committee shall have the authority (i) to exercise all of the
      powers granted to it under the Plan, (ii) to construe, interpret and
      implement the Plan and any Plan agreements executed pursuant to the Plan,
      (iii) to prescribe, amend and rescind rules relating to the Plan, (iv) to
      make any determination necessary or advisable in administering the Plan,
      and (v) to correct any defect, supply any omission and reconcile any
      inconsistency in the Plan.

            (c) The determination of the Committee on all matters relating to
      the Plan or any Plan agreement shall be conclusive.

            (d) No member of the Committee shall be liable for any action or
      determination made in good faith with respect to the Plan or any award
      hereunder.
   5

            (e) Notwithstanding anything to the contrary contained herein: (i)
      until the Partnership shall appoint the members of the Committee, the Plan
      shall be administered by the General Partner(s), and (ii) the General
      Partner(s) may, in their sole discretion, at any time and from time to
      time, resolve to administer the Plan. In either of the foregoing events,
      the term Committee as used herein shall be deemed to mean the General
      Partner(s).

            1.3 Persons Eligible for Awards.

            Awards under Articles 2 and 3 of the Plan may be made to such
officers, employee-directors, Eligible Directors, executive, managerial,
professional or other employees, advisors and consultants ("key personnel") of
the Partnership or its Affiliates, other than Melvin Simon and Herbert Simon, as
the Committee shall from time to time in its sole discretion select. Eligible
Directors shall also receive awards as provided in Article 4 of the Plan.

            1.4 Types of Awards Under Plan.

            (a) Awards may be made under the Plan in the form of (i) stock
      options ("options"), (ii) stock appreciation rights related to an option
      ("related stock appreciation rights"), (iii) stock appreciation rights not
      related to any option ("unrelated stock appreciation rights"), (iv)
      restricted stock awards and (v) performance units, all as more fully set
      forth in Articles 2, 3 and 4.

            (b) Options granted under the Plan may be either (i) "nonqualified"
      stock options subject to the provisions of section 83 of the Code or (ii)
      options intended to qualify for incentive stock option treatment described
      in Code section 422.

            (c) All options when granted are intended to be nonqualified stock
      options, unless the applicable Plan agreement explicitly states that the
      option is intended to be an incentive stock option. If an option is
      intended to be an incentive stock option, and if for any reason such
      option (or any portion thereof) shall not qualify as an incentive stock
      option, then, to the extent of such nonqualification, such option (or
      portion) shall be regarded as a nonqualified stock option appropriately
      granted under the Plan provided that such option (or portion) otherwise
      meets the Plan's requirements relating to nonqualified stock options.

            (d) In the event the Company or an Affiliate consummates a
      transaction described in Code section 424(a), persons who become key
      personnel or directors on account of such transaction may be granted
      options in substitution or as a replacement for options granted by the
      former employer. The Committee, in its sole discretion and consistent with
      Code section 424(a), shall determine the exercise price of the substitute
      options.

            1.5 Shares Available for Awards.

            (a) Subject to Section 5.6 (relating to adjustments upon changes in
      capitalization), the aggregate number of shares of Common Stock (as
      defined in Section 1.6) which may be delivered under the Plan pursuant to
      awards hereunder shall not exceed 10,000,000 shares. The number of
      unrestricted shares acquired pursuant to the exercise of any related stock
      appreciation right pursuant to the Plan shall be deemed to be equal to the
      number of shares surrendered, or as to which the grantee's right to
      purchase, acquire or receive is surrendered, in connection with such
      exercise, and, to the extent that any payment to a grantee upon exercise
      of any stock appreciation right is made in the form of restricted shares,
      the portion of the shares surrendered, or as to which such grantee's right
      to purchase, acquire or receive is surrendered, which is related to
      payment in the form of restricted shares shall not be deemed to be
      unrestricted shares acquired pursuant to the Plan until such restricted
      shares become unrestricted. Upon unconditional vesting of the right of any
      grantee to payment pursuant to any performance unit in cash or any other
      form (other than restricted or unrestricted shares), a number of
      unrestricted shares, equal to the portion of the shares subject to such
      performance unit to which such payment relates, shall be deemed to be
      delivered pursuant to the Plan in connection therewith. The number of
      shares delivered in full or partial payment of any option exercise price
      under the Plan shall be deducted from the number of shares delivered to
      the grantee pursuant to such option for purposes of determining the number
      of unrestricted shares delivered pursuant to the Plan. Without limiting
      the generality of the foregoing, shares of Common Stock covered by awards
      granted under the Plan which expire or terminate for any reason (other
      than an option or part thereof which is canceled by the Committee and for
      which cash is paid in respect thereof pursuant to Section 2.5(f)) shall
      again become available for award under the Plan.

            (b) Shares of Common Stock that shall be subject to issuance
      pursuant to the Plan shall be authorized and unissued or treasury shares
      of Common Stock.

            (c) Without limiting the generality of the foregoing, the Committee
      may, with the grantee's consent, cancel any award under the Plan and issue
      a new award in substitution therefor upon such terms as the Committee may
      in its sole discretion determine, provided that the substituted award
      shall satisfy all applicable Plan requirements as of the date such new
      award is made.

            1.6 Definitions of Certain Terms.

            (a) The term "Affiliate" as used herein means any person or entity
      which, at the time of reference, directly, or indirectly through one or
      more intermediaries, controls, is controlled by, or is under common
      control with, the


                                      -3-
   7

      Partnership, as determined by the Committee in its sole discretion;
      provided, however, that the Company and Affiliates of the Company shall be
      considered Affiliates of the Partnership.

            (b) The term "Common Stock" as used herein means the shares of
      common stock, par value $0.0001 per share, of Simon Property Group, Inc.,
      as constituted on the effective date of the Plan, all rights which trade
      with or are paired with such shares of common stock, including beneficial
      interests in one or more trusts which own all of the common stock of SPG
      Realty Consultants, Inc., and any other shares into which such common
      stock shall thereafter be changed by reason of a recapitalization, merger,
      consolidation, split-up, combination, exchange of shares or the like.

            (c) The term "Eligible Director" means a director of the Company who
      is not an employee of the Partnership or any of its Affiliates.

            (d) Except as otherwise determined by the Committee in its sole
      discretion, the "fair market value" as of any date and in respect of any
      share of Common Stock shall be the mean between the high and low sales
      prices of a share of Common Stock as reported on the New York Stock
      Exchange if shares of Common Stock are then trading upon such exchange, or
      if not, then such average on such other stock exchange on which shares of
      the Common Stock are principally trading, on such date. In no event shall
      the fair market value of any share be less than its par value.

            (e) The term "Performance Cycle" means the period of time
      established by the Committee within which Performance Goals are required
      to be attained or satisfied.

            (f) The term "Performance Goals" means the performance goals
      established by the Committee with respect to the Company, the Partnership
      or any Affiliates, in the Committee's sole discretion, in writing, based
      on any one or any combination of the following business criteria: (a)
      earnings per share; (b) return on equity; (c) return on assets; (d) market
      value per share; (e) funds from operations; (f) return to stockholders
      (including dividends); (g) revenues; (h) market share; (i) cash flow; and
      (j) cost reduction goals. Awards shall be delivered only after it is
      certified, in writing, by the Committee that the Performance Goals as
      established by the Committee have been attained or otherwise satisfied
      within the Performance Cycle.

            1.7 Agreements Evidencing Awards

            (a) Options, stock appreciation rights and restricted stock awards
      granted under the Plan shall be evidenced by written agreements. Other
      awards


                                      -4-
   8

      granted under the Plan shall be evidenced by written agreements to the
      extent the Committee may in its sole discretion deem necessary or
      desirable. Any such written agreements shall (i) contain such provisions
      not inconsistent with the terms of the Plan as the Committee may in its
      sole discretion deem necessary or desirable and (ii) be referred to herein
      as "Plan Agreements."

            (b) Each Plan agreement shall set forth the number of shares of
      Common Stock subject to the award granted thereby.

            (c) Each Plan agreement with respect to the granting of a related
      stock appreciation right shall set forth the number of shares of Common
      Stock subject to the related option which shall also be subject to the
      related stock appreciation right granted thereby.

            (d) Each Plan agreement with respect to the granting of an option
      shall set forth the amount (the "option exercise price") payable by the
      grantee in connection with the exercise of the option evidenced thereby.
      The option exercise price per share shall not be less than the fair market
      value of a share of Common Stock on the date the option is granted.

            (e) Each Plan agreement with respect to a stock appreciation right
      shall set forth the amount (the "appreciation base") over which
      appreciation will be measured upon exercise of the stock appreciation
      right evidenced thereby. The appreciation base per share of Common Stock
      subject to a stock appreciation right shall not be less than (i) in the
      case of an unrelated stock appreciation right, the fair market value of a
      share of Common Stock on the date the stock appreciation right is granted,
      or (ii) in the case of a related stock appreciation right, the option
      exercise price per share of Common Stock subject to the related option.

                                    ARTICLE 2

                                STOCK OPTIONS AND
                            STOCK APPRECIATION RIGHTS

            2.1 Grants of Stock Options.

            The Committee may grant options to purchase shares of Common Stock

from time to time in its sole discretion determine, subject to the terms of the
Plan; provided, however, that the maximum number of shares subject to all awards
granted to any Plan participant pursuant to the Plan shall not exceed 600,000
in any calendar year.

            2.2 Grant of Reload Options.

            The Committee may, subject to Sections 1.5 and 2.1, grant a Reload
Option to any grantee holding an unexercised option. For purposes of the Plan. a
"Reload Option" shall mean an option to purchase a number of shares of Common
Stock granted in connection with the exercise of the grantee's option (the
"Exercised Options") upon the payment of the option exercise price for such
Exercised Option with shares of Common Stock that have a fair market value equal
to not less than 100% of the option exercise price for such Exercised Option.
The Reload Option with respect to an Exercised Option shall be for a number of
shares of Common Stock equal to the number of shares of Common Stock tendered to
exercise the Exercised Option plus, if so provided by the Committee, the number
of shares of Common Stock, if any, retained by the Partnership in connection
with the exercise of the Exercised Option to satisfy any federal, state, or
local tax withholding requirements. Reload options shall be subject to the
following terms and conditions:

                  (i) the grant date for each Reload Option shall be the date of
            exercise of the Exercised Option to which it relates;

                  (ii) the Reload Option may be exercised at any time during the
            unexpired term of the original Exercised Option to which it relates
            (subject to earlier termination thereof as provided in the Plan and
            in the applicable Plan agreement); and

                  (iii) the terms of the Reload Option shall be the same as the
            terms of the Exercised Option to which it relates, except that (1)
            the option exercise price shall be the fair market value of the
            Common Stock on the grant date of the Reload Option and (2) no
            Reload Option may be exercised within one year from the date on
            which such Reload Option was granted.

            2.3 Grant of Stock Appreciation Rights.

            (a) Related Stock Appreciation Rights. The Committee may grant a
      related stock appreciation right in connection with all or any part of an
      option granted under the Plan, either at the time the related option is
      granted or any time thereafter prior to the exercise, termination or
      cancellation of such option, and subject to such terms and conditions as
      the Committee shall from time to time in its sole discretion determine,
      subject to the terms of the Plan. The grantee of a related stock
      appreciation right shall, subject to the terms of the Plan and the
      applicable Plan agreement, have the right to surrender to the Partnership
      for cancellation all or a portion of the related option granted under the
      Plan, but only to the extent that such option is then exercisable, and to
      be paid therefor an amount equal to the excess (if any) of(i) the
      aggregate fair market value of the shares of Common Stock subject to such
      option or portion thereof (determined as


                                      -6-
   10

      of the date of exercise of such stock appreciation right), over (ii) the
      aggregate appreciation base (determined pursuant to Section 1.7(e)) of the
      shares of Common Stock subject to such stock appreciation right or portion
      thereof.

            (b) Unrelated Stock Appreciation Rights. The Committee may grant an
      unrelated stock appreciation right in such amount and subject to such
      terms and conditions, as the Committee shall from time to time in its sole
      discretion determine, subject to the terms of the Plan. The grantee of an
      unrelated stock appreciation right shall, subject to the terms of the Plan
      and the applicable Plan agreement, have the right to surrender to the
      Partnership for cancellation all or a portion of such stock appreciation
      right, but only to the extent that such stock appreciation right is then
      exercisable, and to be paid therefor an amount equal to the excess (if
      any) of (i) the aggregate fair market value of the shares of Common Stock
      subject to such stock appreciation right or portion thereof (determined as
      of the date of exercise of such stock appreciation right), over (ii) the
      aggregate appreciation base (determined pursuant to Section 1.7(e)) of the
      shares of Common Stock subject to such stock appreciation right or portion
      thereof.

            (c) Payment. Unless the Plan agreement provides otherwise, payment
      due to the grantee upon exercise of a stock appreciation right shall be
      made in cash and/or in Common Stock (valued at the fair market value
      thereof as of the date of exercise) as determined by the Committee in its
      sole discretion.

            2.4 Exercise of Related Stock Appreciation Right Reduces Shares
Subject to Option.

            Upon any exercise of a related stock appreciation right or any
portion thereof, the number of shares of Common Stock subject to the related
option shall be reduced by the number of shares of Common Stock in respect of
which such stock appreciation right shall have been exercised.

            2.5 Exercisability of Options and Stock Appreciation Rights.

            Subject to the other provisions of the Plan:

            (a) Exercisability Determined by Plan Agreement. Each Plan agreement
      shall set forth the period during which and the conditions subject to
      which the option or stock appreciation right evidenced thereby shall be
      exercisable, as determined by the Committee in its sole discretion.

            (b) Default Provisions. Unless the applicable Plan agreement
      otherwise specifies:


                                      -7-
   11

                  (i) no option or stock appreciation right shall be exercisable
            prior to the first anniversary of the date of grant;

                  (ii) each option or stock appreciation right granted under the
            Plan shall become cumulatively exercisable with respect to 40% of
            the shares of Common Stock subject thereto, rounded down to the next
            lower full share, on the first anniversary of the date of grant, and
            with respect to an additional 30% of shares of Common Stock subject
            thereto, rounded down to the next lower full share, on the second
            anniversary of the date of the grant;

                  (iii) each option or stock appreciation right shall become
            100% exercisable on the third anniversary of the date of grant;

                  (iv) except as provided in Section 2.7 each option or stock
            appreciation right shall remain 100% exercisable through the day
            prior to the tenth anniversary of the date of grant, after which
            such option or stock appreciation right shall terminate and cease to
            be exercisable; and

                  (v) no option or stock appreciation right shall be exercisable
            to the extent that such exercise will cause the Partnership or
            Affiliate to pay any amount that would be nondeductible by the
            Partnership or such Affiliate by reason of Code section 162(m).

            (c) Exercise of Related Stock Appreciation Right. Unless the
      applicable Plan agreement otherwise provides, a related stock
      appreciation right shall be exercisable at any time during the period that
      the related option may be exercised.

            (d) Partial Exercise Permitted. Unless the applicable Plan agreement
      otherwise provides, an option or stock appreciation right granted under
      the Plan may be exercised from time to time as to all or part of the full
      number of shares as to which such option or stock appreciation right
      shall then be exercisable. No option shall be exercised with respect to
      less than 50 shares of Common Stock unless the option is being exercised
      with respect to the full number of shares issuable hereunder.

            (e) Notice of Exercise; Exercise Date.

                  (i) An option or stock appreciation right shall be exercisable
            by the filing of a written notice of exercise with the Partnership,
            on such form and in such manner as the Committee


                                      -8-
   12

            shall in its sole discretion prescribe, and by payment in accordance
            with Section 2.6.

                  (ii) Unless the applicable Plan agreement otherwise provides
            or the Committee in its sole discretion otherwise determines, the
            date of exercise of an unrelated stock appreciation right shall be
            the date the Partnership receives such written notice of exercise.

                  (iii) For purposes of the Plan, the "option exercise date"
            shall be deemed to be the sixth business day immediately following
            the date written notice of exercise is received by the Partnership.

                  (f) Cashout of Options. If and to the extent that the
      applicable Plan agreement so provides: At any time after receipt of
      written notice of exercise of an option and prior to the "option exercise
      date" (as defined in Section 2.5(e)), the Committee in its sole discretion
      may by written notice to the grantee, cancel the option or any part
      thereof if the Committee in its sole discretion determines that tax, legal
      or contractual restrictions or brokerage or other market considerations
      would make the acquisition of Common Stock, or the grantee's sale of
      Common Stock to the public markets illegal, impracticable or inadvisable.
      If the Committee cancels such option or any part thereof, the Partnership
      shall pay to the grantee, as soon as practicable thereafter, an amount
      equal in cash to the excess of (i) the aggregate fair market value of the
      shares of Common Stock subject to the option or part thereof canceled
      (determined as of the option exercise date), over (ii) the aggregate
      option exercise price of the shares of Common Stock subject to the option
      or part thereof canceled.

            2.6 Payment of Option Price.

            (a) Tender Due Upon Notice of Exercise. Unless the applicable Plan
      agreement otherwise provides or the Committee in its sole discretion
      otherwise determines, (i) any written notice of exercise of an option
      shall be accompanied by payment of the full purchase price for the shares
      being purchased, and (ii) the grantee shall have no right to receive
      shares of Common Stock with respect to an option exercise prior to the
      option exercise date.

            (b) Manner of Payment. Payment of the option exercise price shall be
      made in any combination of the following:

                  (i) by certified or official bank check payable to the Company
            (or the equivalent thereof acceptable to the Committee);


                                      -9-
   13

                  (ii) with the consent of the Committee in its sole discretion,
            by personal check (subject to collection), which may in the
            Committee's sole discretion be deemed conditional;

                  (iii) if and to the extent provided in the applicable Plan
            agreement, by delivery of previously acquired shares of Common Stock
            owned by the grantee for at least six months (or such other period
            as the Committee may prescribe) having a fair market value
            (determined as of the option exercise date) equal to the portion of
            the option exercise price being paid thereby, provided that the
            Committee may require the grantee to furnish an opinion of counsel
            acceptable to the Committee to the effect that such delivery would
            not result in the grantee incurring any liability under Section
            16(b) of the Act and does not require any Consent (as defined in
            Section 5.3);

                  (iv) with the consent of the committee in its sole discretion,
            by the promissory note and agreement of the grantee providing for
            payment with interest on the unpaid balance accruing at a rate not
            less than that needed to avoid the imputation of income under Code
            section 7872 and upon such terms and conditions (including the
            security, if any, therefor) as the Committee may determine in its
            sole discretion; or

                  (v) by any other means which the Committee, in its sole
            discretion, determines to be consistent with the purposes of the
            Plan.

            (c) Cashless Exercise. Payment in accordance with clause (i) of
      Section 2.6(b) may be deemed to be satisfied, if and to the extent
      provided in the applicable Plan agreement, by delivery to the Company of
      an assignment of a sufficient amount of the proceeds from the sale of
      Common Stack acquired upon exercise to pay for all of the Common Stock
      acquired upon exercise and an authorization to the broker or selling agent
      to pay that amount to the Company, which sale shall be made at the
      grantee's direction at the time of exercise, provided that the Committee
      may require the grantee to furnish an opinion of counsel acceptable to the
      Committee to the effect that such delivery would not result in the grantee
      incurring any liability under Section 16(b) of the Act and does not
      require any Consent (as defined in Section 5.3).

            (d) Issuance of Shares. As soon as practicable after receipt of full
      payment, the Company shall, subject to the provisions of Section 5.3,
      deliver to the grantee one or more certificates for the shares of Common
      Stock so purchased, which certificates may bear such legends as the
      Company may deem appropriate


                                      -10-
   14

      concerning restrictions on the disposition of the shares in accordance
      with applicable securities laws, rules and regulations or otherwise.

            2.7 Termination of Service.

            For purposes of the Plan, "termination of service" means, in the
case of an employee, the termination of the employment relationship between the
employee and the Partnership and all Affiliates; and in the case of an
individual who is not an employee, the termination of the service relationship
between the individual and the Partnership and all Affiliates. Subject to the
other provisions of the Plan and unless the applicable Plan agreement otherwise
provides:

            (a) General Rule. All options and stock appreciation rights granted
      to a grantee shall terminate upon his termination of service for any
      reason (including death) except to the extent post-service exercise of the
      vested portion of an option or stock appreciation right is permitted in
      accordance with this Section 2.7. The "vested portion" of any option or
      stock appreciation right shall mean the portion thereof which is
      exercisable immediately prior to the grantee's termination of service for
      any reason.

            (b) Improper Activity. All options and stock appreciation rights
      granted to a grantee shall terminate and expire on the day of the
      grantee's termination of service for cause, whether or not the grantee is
      a party to a written service contract. For purposes of this Section 2.7, a
      grantee's service shall be deemed to be terminated for "cause" if he is
      discharged (i) on account of fraud, embezzlement or other unlawful or
      tortious conduct, whether or not involving or against the Partnership or
      any Affiliate, (ii) for violation of a policy of the Partnership or any
      Affiliate, (iii) for serious and willful acts of misconduct detrimental to
      the business or reputation of the Partnership or any Affiliate or (iv)for
      "cause" or any like term as defined in any written contract with the
      grantee.

            (c) Regular Termination; Leaves of Absence. If the grantee's service
      terminates for reasons other than as provided in subsection (b) or (d) of
      this Section 2.7, the portion of options and stock appreciation rights
      granted to such grantee which were exercisable immediately prior to such
      termination of service may be exercised until the earlier of (i) 30 days
      after his termination of service or (ii) the date on which such options
      and stock appreciation rights terminate or expire in accordance with the
      provisions of the Plan (other than this Section 2.7) and the Plan
      agreement; provided, that the Committee may in its sole discretion
      determine such other period for exercise in the case of an individual
      whose service terminates solely because the employer ceases to be an
      Affiliate or the grantee transfers employment with the Partnership's
      consent to a purchaser of a business disposed of by the Partnership. The
      Committee may in its sole discretion


                                      -11-
   15

      determine (i) whether any leave of absence (including short-term or
      long-term disability or medical leave) shall constitute a termination of
      service for purposes of the Plan, and (ii) the impact, if any, of any such
      leave on outstanding awards under the Plan.

            (d) Death; Disability; Retirement. If a grantee's service terminates
      by reason of death, disability, or retirement at or after age 65, the
      portion of options and stock appreciation rights granted to such grantee
      which were exercisable immediately prior to such termination of service
      may be exercised until the earlier of (i) one year after his termination
      of service in the case of death or disability or three years after his
      termination of service by reason of retirement, or (ii) the date on which
      such options and stock appreciation rights terminate or expire in
      accordance with the Plan agreement. For purposes of this Section 2.7, the
      term "disability" shall mean, with respect to any grantee, a "permanent
      and total disability" as defined in section 22(e)C3) of the Code.

            2.8 Special ISO Requirements.

            In order for a grantee to receive special tax treatment with respect
to stock acquired under an option intended to be an incentive stock option, the
grantee of such option must be, at all times during the period beginning on the
date of grant and ending on the day three months before the date of exercise of
such option, an employee of the Company or any of the Company's parent or
subsidiary corporations (within the meaning of Code section 424), or of a
corporation or a parent or subsidiary corporation of such corporation issuing or
assuming a stock option in a transaction to which Code section 424(a) applies.
The aggregate fair market value, determined as of the date an option is granted,
of the Common Stock for which any grantee may be awarded incentive stock options
which are first exercisable by the grantee during any calendar year under the
Plan (and any other stock option plan to be taken into account under Code
section 422(d)) shall not exceed $100,000. If an option granted under the Plan
is intended to be an incentive stock option, and if the grantee, at the time of
grant, owns stock possessing 10% or more of the total combined voting power of
all classes of stock of the grantee's employer corporation or of its parent or
subsidiary corporation, then (i) the option exercise price per share shall in no
event be less than 110% of the fair market value of the Common Stock on the date
of such grant and (ii) such option shall not be exercisable after the expiration
of five years after the date such option is granted.

                                    ARTICLE 3

                       AWARDS OTHER THAN STOCK OPTIONS AND
                            STOCK APPRECIATION RIGHTS

            3.1 Restricted Stock Awards.

            (a) Grant of Awards. The Committee may grant restricted stock
      awards, alone or in tandem with other awards, under the Plan in such
      amounts and subject to such terms and conditions as the Committee shall
      from time to time in its sole discretion determine. The vesting of a
      restricted stock award granted under the Plan may be conditioned upon the
      completion of a specified period of service with the Partnership or any
      Affiliate, upon the attainment of specified Performance Goals within
      specified Performance Cycles, and/or upon such other criteria as the
      Committee may determine in its sole discretion.

            (b) Payment. Each Plan agreement with respect to a restricted stock
      award shall set forth the amount (if any) to be paid by the grantee with
      respect to such award. If a grantee makes any payment for a restricted
      stock award which does not vest, appropriate payment may be made to the
      grantee following the forfeiture of such award on such terms and
      conditions as the Committee may determine.

            (c) Forfeiture Upon Termination of Service. Unless the applicable
      Plan agreement otherwise provides or the Committee otherwise determines,
      (i) if a grantee's service terminates for any reason (other than death)
      before all of his restricted stock awards have vested, such unvested
      awards shall terminate and expire upon such termination of service, and
      (ii) in the event any condition to the vesting of restricted stock awards
      is not satisfied within the period of time permitted therefor, such
      restricted shares shall be returned to the Partnership. If a grantee's
      service terminates by reason of death, any unvested portion of a
      restricted stock award which has been earned as a result of the attainment
      of applicable Performance Goals shall be fully vested as of the awardee's
      date of death.

            (d) Issuance of Shares. The Committee may provide that one or more
      certificates representing restricted stock awards shall be registered in
      the grantee's name and bear an appropriate legend specifying that such
      shares are not transferable and are subject to the terms and conditions of
      the Plan and the applicable Plan agreement, or that such certificate or
      certificates shall be held in escrow by the Partnership on behalf of the
      grantee until such shares vest or are forfeited, all on such terms and
      conditions as the Committee may determine. Unless the applicable Plan
      agreement otherwise provides, no share of restricted stock may be
      assigned, transferred, otherwise encumbered or disposed of by the grantee
      until such share has vested in accordance with the terms of such award.
      Subject to the provisions of Section 5.4, as soon as practicable after any
      restricted stock award shall vest, the Partnership shall issue or reissue
      to the grantee (or to his designated beneficiary in the event of the
      grantee's death) one or more


                                      -13-
   17

      certificates for the Common Stock represented by such restricted stock
      award without such restricted legend.

            (e) Grantees' Rights Regarding Restricted Stock. Unless the
      applicable Plan agreement otherwise provides, (i) a grantee may vote and
      receive dividends on restricted stock awarded under the Plan, and (ii) any
      stock received as a dividend on, or in connection with a stock split of, a
      restricted stock award shall be subject to the same restrictions as such
      restricted stock.

            3.2 Common Stock Awards.

            The Committee may issue awards under the Plan, payable in Common
Stock, including, but not limited to awards of Common Stock equal to dividends
declared on Common Stock, alone or in tandem with other awards, in such amounts
and subject to such terms and conditions as the Committee shall from time to
time in its sole discretion determine. Such Common Stock awards under the Plan
shall relate to a specified maximum number of shares granted as, or in payment
of, a bonus, or to provide incentives or recognize special achievements or
contributions.

            3.3 Performance Units.

            (a) Grant of Units. The Committee may grant performance units under
      the Plan to acquire shares of Common Stock in such amounts and subject to
      such terms and conditions as the Committee shall from time to time in its
      sole discretion determine, subject to the terms of the Plan.

            (b) Performance Units. Each performance unit under the Plan shall
      relate to a specified maximum number of shares, and shall be exchangeable
      for all or a portion of such shares, or cash (or such other form of
      consideration as may be determined by the Committee in its sole discretion
      equivalent in value thereto) in up to an amount equal to the fair market
      value of an equal number of unrestricted shares, at the end of a specified
      Performance Cycle as may be established by the Committee. The number of
      such shares which may be deliverable pursuant to such performance unit
      shall be based upon the degree of attainment of Performance Goals over a
      Performance Cycle as may be established by the Committee. The Committee
      may provide for full or partial credit, prior to completion of such
      Performance Cycle or achievement of the degree of attainment of the
      Performance Goals specified in connection with such performance unit, in
      the event of the participant's death, normal retirement, early retirement,
      or total or permanent disability, or in such other circumstances as the
      Committee may determine in its sole discretion to be fair and equitable to
      the participant or in the interest of the Partnership and its Affiliates.

                                    ARTICLE 4

                       OPTION GRANTS TO ELIGIBLE DIRECTORS

            4.1 Grants to Eligible Directors.

            Each Eligible Director of the Company shall be granted options in
accordance with this Article 4. All options granted pursuant to this Article 4
shall constitute "non-qualified" stock options.

            4.2 Amount of Grants. Each person who is hereafter elected as an
Eligible Director shall receive the following options:

            (a) Initial Election. Each Eligible Director who is elected or
      appointed a director of the Company and who has not previously served as a
      director of Simon DeBartolo Group, Inc., or Corporate Property Investors,
      Inc., shall be granted options to purchase 5,000 shares of Common Stock on
      the first day of the first calendar month following the month in which
      such person first becomes an Eligible Director.

            (b) Reelection. As of the date of each annual meeting of the
      Company's stockholders (the "Annual Meeting") held after January 1, 1999,
      each Eligible Director shall be granted options to purchase 3,000 shares
      of Common Stock multiplied by the member of calendar years that have
      elapsed since such person was previously elected a director of the
      Company, Simon DeBartolo Group, Inc., or Corporate Property Investors,
      Inc. (the "Subsequent Awards"); provided, however, that if a person is
      elected, appointed or otherwise becomes an Eligible Director during a
      period 60 days prior to the Annual Meeting in any year, then such Eligible
      Director will receive no Subsequent Awards, and provided, further, that
      each Eligible Director receiving Subsequent Awards must continue to serve
      as a director of the Company after such Annual Meeting.

            4.3 Terms of Options.

            (a) Exercise Price and Exercise Period. The exercise price of all
      options granted pursuant to this Article 4 shall be equal to the fair
      market value of the Common Stock on the date of grant. All options granted
      pursuant to this Article 4 shall become exercisable on the first
      anniversary of the date of grant or such earlier time as a Change in
      Control, as hereinafter defined, of the Company and will remain
      exercisable through the tenth anniversary of the date of grant (the
      "Expiration Date"). Prior to the Expiration Date, options granted pursuant
      to this Article 4 shall terminate 30 days after the optionee ceases to be
      a member of the Board of Directors of the Company.


                                      -15-
   19

            (b) Payment. An optionee may pay the exercise price of any options
      granted pursuant to this Article 4 (i) by certified or official bank check
      payable to the Company; (ii) by delivery of previously acquired shares of
      Common Stock held by such optionee for at least six months having a fair
      market value equal to the purchase of the option exercise price being paid
      thereby; or (iii) or any combination of the foregoing.

            4.4 Transfer of Options.

            No option granted pursuant to this Article 4 may be sold, assigned
or otherwise transferred by an Eligible Director other than by will or the laws
of descent or distribution and may be exercised during the Eligible Director's
lifetime only by such Eligible Director.

            4.5 Change of Control.

            In the event of a Change of Control prior to the date an option
granted under this Article 4 terminates, each option not previously vested shall
become immediately vested and exercisable in full. For this purpose, a "Change
of Control" shall mean (i) a merger or consolidation of the Company with another
corporation, whether or nor the Company is the surviving corporation, where
there is a change in the shares of stock by reason of such merger or
consolidation, (ii) an acquisition of all or substantially all of the assets of
the Company by another person, or (iii) a reorganization or liquidation of the
Company.

                                    ARTICLE 5

                                  MISCELLANEOUS

            5.1 Amendment of the Plan; Modification of Awards.

            (a) Plan Amendments. The Partnership, by action of its General
      Partner(s), may, without approval of other partners in the Partnership, at
      any time and from time to time suspend, discontinue or amend the Plan in
      any respect whatsoever, except that no such amendment shall impair any
      rights under any award theretofore made under the Plan without the consent
      of the grantee of such award. Furthermore, shareholder approval of any
      Plan amendment shall be obtained in such a manner and to such a degree as
      is required by applicable law or regulation.

            (b) Award Modifications. With the consent of the grantee and subject
      to the terms and conditions of the Plan (including Section 5.1(a)), the
      Committee may amend outstanding Plan agreements with such grantee,
      including, without limitation, any amendment which would (i) accelerate
      the time or times at which


                                      -16-
   20

      an award may vest or become exercisable and/or (ii) extend the scheduled
      termination or expiration date of the award.

            5.2 Limitation on Exercise. No option or stock appreciation right
shall be exercisable to the extent that such exercise will cause the Partnership
or any Affiliate to pay any amount which would be nondeductible by the
Partnership or such Affiliate by reason of Code section 162(m).

            5.3 Restrictions.

            (a) Consent Requirements. If the Committee shall at any time
      determine in its sole discretion that any Consent (as hereinafter defined)
      is necessary or desirable as a condition of, or in connection with, the
      granting of any award under the Plan, the acquisition, issuance or
      purchase of shares or other rights hereunder or the taking of any other
      action hereunder (each such action being hereinafter referred to as a
      "Plan Action"), then such Plan Action shall not be taken, in whole or in
      part, unless and until such Consent shall have been effected or obtained
      to the full satisfaction of the Committee. Without limiting the generality
      of the foregoing, if (i) the Committee may make any payment under the Plan
      in cash, Common Stock or both, and (ii) the Committee determines that
      Consent is necessary or desirable as a condition of, or in connection
      with, payment in any one or more of such forms, then the Committee shall
      be entitled to determine not to make any payment whatsoever until such
      Consent has been obtained.

            (b) Consent Defined. The term "Consent" as used herein with respect
      to any Plan Action means (i) any and all listings, registrations or
      qualifications in respect thereof upon any securities exchange or other
      self-regulatory organization or under any federal, state or local law,
      rule or regulation, (ii) the expiration, elimination or satisfaction of
      any prohibitions, restrictions or limitations under any federal, state or
      local law, rule or regulation or the rules of any securities exchange or
      other self-regulatory organization, (iii) any and all written agreements
      and representations by the grantee with respect to the disposition of
      shares, or with respect to any other matter, which the Committee shall
      deem necessary or desirable to comply with the terms of any such listing,
      registration or qualification or to obtain an exemption from the
      requirement that any such listing, qualification or registration be made,
      and (iv) any and all consents, clearances and approvals in respect of a
      Plan Action by any governmental or other regulatory bodies or any parties
      to any loan agreements or other contractual obligations of the Partnership
      or any Affiliate.

            5.4 Nontransferability.

            Except as expressly authorized by the Committee in the Plan
agreement, no award granted to any grantee under the Plan shall be assignable or
transferable by the grantee other than by will or by the laws of descent and
distribution and during the lifetime of the grantee, all rights with respect to
any option or stock appreciation right granted to the grantee under the Plan
shall be exercisable only by the grantee.

            5.5 Withholding Taxes.

            (a) Whenever under the Plan shares of Common Stock are to be
      delivered pursuant to an award, the Committee may require as a condition
      of delivery that the grantee remit an amount sufficient to satisfy all
      federal, state and other governmental withholding tax requirements related
      thereto. Whenever cash is to be paid under the Plan (whether upon the
      exercise of stock appreciation right or otherwise), the Partnership may,
      as a condition of its payment, deduct therefrom, or from any salary or
      other payments due to the grantee, an amount sufficient to satisfy all
      federal, state and other governmental withholding tax requirements related
      thereto or to the delivery of any shares of Common Stock under the Plan.

            (b) Without limiting the generality of the foregoing, (i) a grantee
      may elect to satisfy all or part of the foregoing withholding requirements
      by delivery of unrestricted shares of Common Stock owned by the grantee
      for at least six months (or such other period as the Committee may
      determine in its sole discretion) having a fair market value (determined
      as of the date of such delivery by the grantee) equal to all or part of
      the amount to be so withheld, provided that the Committee may require, as
      a condition of accepting any such delivery, the grantee to furnish an
      opinion of counsel acceptable to the Committee to the effect that such
      delivery would not result in the grantee incurring any liability under
      Section 16(b) of the Act; and (ii) the Committee may permit any such
      delivery to be made by withholding shares of Common Stock from the shares
      otherwise issuable pursuant to the award giving rise to the tax
      withholding obligation (in which event the date of delivery shall be
      deemed the date such award was exercised).

            5.6 Adjustments Upon Changes in Capitalization.

            If and to the extent specified by the Committee, the number of
shares of Common Stock which may be issued pursuant to awards under the Plan,
the number of shares of Common Stock subject to awards, the option exercise
price and appreciation base of options and stock appreciation rights theretofore
granted under the Plan, and the amount payable by a grantee in respect of an
award, shall be appropriately adjusted (as the Committee may determine) for any
change in the number of issued shares of Common Stock resulting from the
subdivision or


                                      -18-
   22

combination of shares of Common Stock or other capital adjustments, or the
payment of a stock dividend after the effective date of the Plan, or other
change in such shares of Common Stock effected without receipt of consideration
by the Company; provided that any awards covering fractional shares of Common
Stock resulting from any such adjustment shall be eliminated and provided
further, that each incentive stock option granted under the Plan shall not be
adjusted in a manner that causes such option to fail to continue to qualify as
an "incentive stock option" within the meaning of Code section 422. Adjustments
under this Section shall be made by the Committee, whose determination as to
what adjustments shall be made, and the extent thereof, shall be final, binding
and conclusive.

            5.7 Right of Discharge Reserved.

            Nothing in the Plan or in any Plan agreement shall confer upon any
person the right to continue in the service of the Partnership or any Affiliate
or affect any right which the Partnership or any Affiliate may have to terminate
the service of such person.

            5.8 No Rights as a Stockholder.

            No grantee or other person shall have any of the rights of a
stockholder of the Company with respect to shares subject to an award until the
issuance of a stock certificate to him for such shares. Except as otherwise
provided in Section 5.6, no adjustment shall be made for dividends,
distributions or other rights (whether ordinary or extraordinary, and whether in
cash, securities or other property) for which the record date is prior to the
date such stock certificate is issued. In the case of a grantee of an award
which has not yet vested, the grantee shall have the rights of a stockholder of
the Company if and only to the extent provided in the applicable Plan agreement.

            5.9 Nature of Payments.

            (a) Any and all awards or payments hereunder shall be granted,
      issued, delivered or paid, as the case may be, in consideration of
      services performed for the Partnership or its Affiliates by the grantee.

            (b) No such awards and payments shall be considered special
      incentive payments to the grantee or, unless otherwise determined by the
      Committee, be taken into account in computing the grantee's salary or
      compensation for the purposes of determining any benefits under (i) any
      pension, retirement, life insurance or other benefit plan of the
      Partnership or any Affiliate or (ii) any agreement between the Partnership
      or any Affiliate and the grantee.

            (c) By accepting an award under the Plan, the grantee shall thereby
      waive any claim to continued exercise or vesting of an award or to damages
      or severance entitlement related to non-continuation of the award beyond
      the period provided herein or in the applicable Plan agreement,
      notwithstanding any contrary


                                      -19-
   23

      provision in any written contract with the grantee, whether any such
      contract is executed before or after the grant date of the award.

            5.10 Non-Uniform Determinations.

            The Committee's determinations under the Plan need not be uniform
and may be made by it selectively among persons who receive, or are eligible to
receive, awards under the Plan (whether or not such persons are similarly
situated). Without limiting the generality of the foregoing, the Committee shall
be entitled, among other things, to make non-uniform and selective
determinations, and to enter into non-uniform and selective Plan agreements, as
to (a) the persons to receive awards under the Plan, (b) the terms and
provisions of awards under the Plan, (c) the exercise by the Committee of its
discretion in respect of the exercise of stock appreciation rights pursuant to
the terms of the Plan, and (d) the treatment of leaves of absence pursuant to
Section 2.7(c).

            5.11 Other Payments or Awards.

            Nothing contained in the Plan shall be deemed in any way to limit or
restrict the Partnership, any Affiliate or the Committee from making any award
or payment to any person under any other plan, arrangement or understanding,
whether now existing or hereafter in effect.

            5.12 Reorganization.

            (a) In the event that the Company is merged or consolidated with
      another corporation and, whether or not the Company shall be the surviving
      corporation, there shall be any change in the shares of Common Stock by
      reason of such merger or consolidation, or in the event that all or
      substantially all of the assets of the Company are acquired by another
      person, or in the event of a reorganization or liquidation of the Company
      (each such event being hereinafter referred to as a "Reorganization
      Event") or in the event that the Board of Directors of the Company (the
      "Board") shall propose that the Company enter into a Reorganization Event,
      then the Committee may in its sole discretion, by written notice to a
      grantee, provide that his options and stock appreciation rights will be
      terminated unless exercised within 30 days (or such longer period as the
      committee shall determine in its sole discretion) after the date of such
      notice; provided that if the Committee takes such action the Committee
      also shall accelerate the dates upon which all outstanding options and
      stock appreciation rights of such grantee shall be exercisable. The 
      Committee also may in its sole


                                      -20-
   24

      discretion by written notice to a grantee provide that all or some of the
      restrictions on any of his awards may lapse in the event of a
      Reorganization Event upon such terms and conditions as the Committee may
      determine.

            (b) Whenever deemed appropriate by the Committee, the actions
      referred to in Section 5.12(a) may be made conditional upon the
      consummation of the applicable Reorganization Event.

            5.13 Section Headings.

            The section headings contained herein are for the purposes of
convenience only and are not intended to define or limit the contents of said
sections.

            5.14 Effective Date and Term of Plan.

            (a) The Plan shall be deemed adopted upon approval by the
      stockholders of Simon DeBartolo Group, Inc. and Corporate Property
      Investors, Inc., but shall not become effective until the consummation of
      the transactions contemplated by the Agreement and Plan of Merger dated as
      of February 18, 1998, among Simon DeBartolo Group, Inc., Corporate
      Property Investors, Inc., and Corporate Realty Consultants, Inc.

            (b) The Plan shall terminate 10 years after the date on which it is
      adopted and no awards shall thereafter be made under the Plan.
      Notwithstanding the foregoing, all awards made under the Plan prior to
      such termination date shall remain in effect until such awards have been
      satisfied or terminated in accordance with the terms and provisions of the
      Plan and the applicable Plan agreement.

            5.15 Governing Law.

            THE PLAN SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE
APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE.
