                          URBAN SHOPPING CENTERS, INC.
                            EMPLOYEE SEVERANCE PLAN

                                    SECTION 1

                                     GENERAL

     1.1. BACKGROUND. Urban Shopping Centers, Inc., a Maryland corporation (the
"Company"), is the general partner of Urban Shopping Centers, L.P. (the
"Partnership"), an Illinois limited partnership. The Partnership owns all of the
preferred stock of Urban Retail Properties Co. (the "Management Company"), a
Delaware corporation. The Company, the Partnership, and the Management Company
are each referred to individually as an "Affiliated Company," and collectively
as the "Affiliated Companies."

     1.2. PURPOSE AND EFFECTIVE DATE. The Company has established the Urban
Shopping Centers, Inc. Employee Severance Plan (the "Plan") effective January 1,
1999 (the "Effective Date") so that it and each of the Affiliated Companies
which, with the consent of the Company, adopts the Plan, may provide severance
pay and benefits to eligible employees as readjustment assistance while seeking
another position due to certain covered terminations of employment. The
Affiliated Companies (including the Company), the employees of which participate
in the Plan, are referred to below, collectively, as the "Employers" and
individually as an "Employer."

     1.3. PLAN ADMINISTRATION. The authority to control and manage the operation
and administration of the Plan shall be vested in the Executive Compensation
Committee of the Board of Directors of the Company (the "Committee"). The
members of the Committee shall be "named fiduciaries" as described in section
402 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), with respect to their authority under the Plan. Except as otherwise
specifically provided in Section 4, the Company shall be the administrator of
the Plan and shall have the rights, duties, and obligations of an
"administrator" as that term is defined in Section 3(16)(A) of ERISA.

     1.4. SOURCE OF PAYMENTS. The obligations of the Company and the other
Employers under the Plan are purely contractual. Any amount payable under the
terms of the Plan shall be paid from the general assets of the Company or the
Employer, as applicable, and no trust or other separate fund shall be
established for this purpose.

     1.5. NOTICES. Any notice or document required to be filed under the Plan
shall be considered to be properly filed if delivered or mailed by registered
mail, postage prepaid, to the Committee, in care of the Company, to the
attention of the Corporate Secretary, at 900 North Michigan Avenue, Chicago,
Illinois 60611. Any notice required under the Plan may be waived by the person
entitled thereto.

<PAGE>

     1.6. ACTION BY AFFILIATED COMPANY. Any action required or permitted to be
taken by an Affiliated Company which is a corporation shall be by resolution of
its board of directors or by a duly authorized officer of such company. Any
action required or permitted to be taken under the Plan by an Affiliated Company
which is a partnership shall be made by writing adopted or executed by its
general partner or by a person or persons authorized in writing by its general
partner. Any action required or permitted to be taken under the Plan by an
Affiliated Company which is a limited liability company shall be made by writing
adopted or executed by its board of directors or managing member or by a person
or persons authorized by its board of directors or managing member, as called
for by such limited liability company's governing agreement.

     1.7. GENDER AND NUMBER. Where the context admits, words in any gender shall
include the other gender, words in the singular shall include the plural, and
the plural shall include the singular.

     1.8. GOVERNING LAWS. The Plan shall be construed and administered in
accordance with the internal laws of the State of Illinois, to the extent that
such laws are not preempted by the laws of the United States of America.

     1.9. PLAN YEAR. The Plan Year shall be calendar year.

     1.10. PLAN NOT GUARANTEE OF EMPLOYMENT. The Plan does not constitute a
guarantee of employment by the Company or any other Affiliated Company, and
participation in the Plan will not give any individual the right to be retained
in the employ of the Company or any other Affiliated Company, nor any right or
claim to any benefit under the Plan, unless such right or claim has specifically
arisen under the Plan. The Company and the other Affiliated Companies reserve
all of their respective rights to terminate the employment relationship of any
employee, with or without cause, at any time, for any reason. The Company and
the other Affiliated Companies reserve all of their respective rights to amend
or modify any of the terms and conditions of the employment of any individual.

                                    SECTION 2

                                  PARTICIPATION

     2.1. PARTICIPATION. Each employee of the Company or an Employer shall
become a "Participant" in the Plan upon the later of the Effective Date or the
date on which he meets all of the following requirements:

<PAGE>

     (a)  he is classified as a regular employee of the Company or an Employer
          (as determined in accordance with the customary practices of the
          Company or Employer, as applicable);

     (b)  he is not employed as a member of a unit of employees whose wages,
          benefits and conditions of employment are determined by a collective
          bargaining agreement unless and until such agreement expressly
          provides for participation in the Plan; and

     (c)  he is not a participant in the Urban Shopping Centers Executive
          Severance Plan or the Urban Shopping Centers Senior Executive
          Parachute Plan and he is not a participant in another severance pay
          plan maintained by the Company or any Affiliated Company.

     2.2. DURATION OF PARTICIPATION. An individual shall cease to be a
Participant in, or to have any rights under, the Plan on the date on which he
ceases to meet all of the requirements of subsection 2.1, unless he is then
eligible to receive benefits under the provisions of Section 3, and, subject to
the terms and conditions of the Plan, he shall again become a Participant in
accordance with subsection 2.1 if he again satisfies the requirements of
subsection 2.1. A Participant who is entitled to payment of a benefit under the
provisions of Section 3 shall remain a Participant in the Plan until the full
amount of his benefit has been paid.

                                    SECTION 3

                               SEVERANCE BENEFITS

     3.1. ENTITLEMENT TO SEVERANCE BENEFITS. Subject to the terms and conditions
of the Plan, a Participant will be entitled to a "Severance Benefit" in an
amount determined in accordance with the provisions of subsection 3.4 in the
event of both a Change in Control and Change in Circumstances with respect to
such Participant, as such terms are defined below.

     3.2. CHANGE IN CONTROL. The term "Change in Control" means the first to
occur of the following events:

     (a)  any person or group of commonly controlled persons other than JMB
          Realty Corporation or any of its affiliated or associated entities
          owns or controls, directly or indirectly, fifty percent (50%) or more
          of the voting control or value of the capital stock of the Company; or

     (b)  any person or group of commonly controlled persons other than JMB
          Realty Corporation or any of its affiliated or associated entities
          owns or controls, directly or indirectly, twenty percent (20%) or more
          of the voting control or value of the capital stock of the Company and
          such ownership or control percentage is greater

<PAGE>

          than the then ownership or control percentage of JMB Realty
          Corporation and all of its affiliated or associated entities; or

     (c)  the shareholders of the Company approve an agreement to merge or
          consolidate with another corporation or other entity (other than JMB
          Realty Corporation or any of its affiliated or associated entities)
          resulting (whether separately or in connection with a series of
          transactions) in a change in ownership of twenty percent (20%) or more
          of the voting control or value of the capital stock of the Company, or
          an agreement to sell or otherwise dispose of all or substantially all
          of the Company's assets (including, without limitation, a plan of
          liquidation or dissolution), or otherwise approve of a fundamental
          alteration in the nature of the Company's business.

Notwithstanding the foregoing provisions of this subsection 3.2, the ownership
of capital stock by the Chief Executive Officer of the Company, by other senior
management employees of the Company or an Employer who are Participants, by JMB
Realty Corporation or by any of its affiliated or associated entities and/or
their respective affiliates shall not be deemed to result in a "Change in
Control" of the Company.

     3.3. CHANGE IN CIRCUMSTANCE. "Change in Circumstances" means the occurrence
of any of the following within twenty-four months of a Change in Control while
the Participant is employed by an Employer:

     (i)  the Participant's voluntary termination of employment within 120 days
          following a demotion or reduction in the Participant's job
          responsibility from that in effect immediately prior to the Change in
          Control, where such reduced job responsibility is not commensurate
          with the Participant's training and experience;

     (ii) the Participant's voluntary termination of employment within 120 days
          following a reduction in the Participant's Base Salary in an amount
          which equal or exceeds three(3) percent of such Base Salary, as
          defined in subsection 3.4, as in effect immediately prior to the
          Change in Control;

    (iii) the Participant's voluntary termination of employment within 120 days
          following the Participant's relocation to a location not within fifty
          miles of his office or job location on the date of the Change in
          Control, except for required travel on the Company's business to an
          extent substantially consistent with his business travel obligations
          as in effect immediately prior to the Change in Control; or

     (iv) the Participant's involuntary termination of employment by the Company
          without Cause.

<PAGE>

For purposes of the Plan, the term "Cause" means a Participant's violation of a
policy, rule or procedure of his Employer, misconduct, unsatisfactory
performance of his duties, or similar circumstances, each as determined by the
Committee or its delegate, in its sole discretion.

     3.4. AMOUNT OF SEVERANCE BENEFIT. Subject to the terms and conditions of
the Plan, if a Participant becomes entitled to a Severance Benefit in accordance
with the foregoing provisions of this Section 3, then the amount of his
Severance Benefit shall be determined in accordance with the following:

     (a)  The Severance Benefit for a Participant who has not attained age 40 on
          the his or her Severance Date shall be equal to the greater of:

          (1)  eight (8) weeks' Base Salary; or

          (2)  the sum of:

               (i)  two (2) weeks' Base Salary for each full year of continuous
                    service with the Company or an Affiliated Company; and

               (ii) one (1) week's Base Salary for each increment of $5,000 by
                    which the Participant's annualized Base Salary exceeds
                    $50,000.

     (b)  The Severance Benefit for a Participant who has attained age 40 on or
          before his or her Severance Date shall be equal to the greater of:

          (1)  eight weeks' Base Salary; or

          (2)  the sum of:

               (i)  two (2) weeks' Base Salary for each full year of continuous
                    service with the Company or an Affiliated Company;

               (ii) one (1) week's Base Salary for each increment of $5,000 by
                    which the Participant's annualized Base Salary exceeds
                    $50,000; and

              (iii) one (1) week's Base Salary for every two whole years by
                    which the Participant's age exceeds age 40 years as of the
                    Participant's Severance Date.

For purposes of the Plan, "Base Salary" for a Participant means the amount of
the Participant's base salary from an Employer at the rate in effect immediately
prior to the Participant's Severance Date, excluding bonuses, overtime and
premium pay, shift differentials, incentive

<PAGE>

compensation and all other compensation; provided, however, that if the
Participant's base salary at the rate in effect immediately prior to the date of
the Change in Control is greater than the Participant's base salary at the rate
in effect immediately prior to his Severance Date, then with respect to such
Participant, "Base Salary" means the amount of the Participant's base salary at
the rate in effect immediately prior to the date of the Change in Control
preceding his Severance Date, excluding bonuses, overtime and premium pay, shift
differentials, incentive compensation and all other compensation. A
Participant's "Severance Date" is the date on which the Change in Circumstance
occurs with respect to the Participant, which is coincident with or follows a
Change in Control.

     3.5. MAXIMUM SEVERANCE BENEFIT. Notwithstanding any other provision of the
Plan, and except as otherwise provided in this subsection 3.5, in no event shall
the Severance Benefit to which any Participant is entitled exceed an amount
equal to the Participant's annual Base Salary as of the date immediately prior
to the Participant's Severance Date; provided, however, that if the
Participant's annual Base Salary as of the date immediately prior to the date of
the Change in Control is greater than it is as of the date immediately prior to
his Severance Date, then the Severance Benefit to which such Participant is
entitled shall not exceed an amount equal to the Participant's annual Base
Salary as of the date immediately prior to the Change in Control. In addition,
if the maximum Severance Benefit described in the immediately preceding sentence
exceeds an amount equal to twice the Participant's annual compensation for the
calendar year ending immediately prior to the Participant's Severance Date, then
the Severance Benefit payable to the Participant shall be reduced so that it
will not exceed such amount. For purposes of this subsection 3.5, a
Participant's annual compensation shall be determined in accordance with
Department of Labor regulation 2510.3-2(b)(2)(i).

     3.6. PAYMENT OF SEVERANCE BENEFIT. A Participant's Severance Benefit
described in this Section 3 shall be payable in installments commencing as of
the first regular pay date after the Participant's "Severance Date".
Notwithstanding the foregoing, in no event shall the period over which the
Severance Benefit under the Plan shall be paid exceed 24 months. The Committee,
in its sole discretion, may accelerate the payment of any amount payable under
the Plan or may pay any amount in a lump sum.

     3.7. REEMPLOYMENT. If a Participant is receiving a Severance Benefit and
the Participant is rehired by the Company or an Employer, payment of his
Severance Benefit shall cease as of the date he first again becomes a
Participant in the Plan in accordance with subsection 2.1. If a Participant is
employed or reemployed by the Company or an Affiliated Company after receiving a
Severance Benefit attributable to a prior period of employment by the Company or
any Affiliated Company, such prior period of employment shall be disregarded for
purposes of determining the amount of the Severance Benefit to which the
Participant is entitled on account of any subsequent termination of employment.

     3.8. OTHER BENEFITS. The Severance Benefit to which a Participant is
entitled under this Section 3 shall be payable in addition to, and not in lieu
of, all other compensation and

<PAGE>

benefits accrued by or payable to the Participant, including but not limited to,
accrued vacation pay and benefits payable under any pension or savings plan, or
any life insurance, medical or disability plan. In addition, the Participant and
his eligible dependents will be entitled to continue to be covered at the
Employer's expense under the Employer's health, dental, and life insurance plans
as in effect at the Participant's termination of employment, or under comparable
plans, for a period of time equal to the number of weeks during which the
Participant is entitled to a Severance Benefit in accordance with subsection
3.4; provided however, that such benefits shall cease upon the Participant's
employment by a new entity under which comparable benefits are available.

     3.9. NONALIENATION. Participants shall not have any right to pledge,
hypothecate, anticipate, or in any way create a lien upon any benefits provided
under this Plan, and no benefits payable hereunder shall be assignable in
anticipation of payment, either by voluntary or involuntary acts, or by
operation of law. Nothing in this subsection 3.9 shall limit a Participant's
rights or powers to dispose of his property by will, limit any rights or powers
which his executor or administrator would otherwise have with regard to benefits
to which a Participant is entitled hereunder, or restrict any right of set-off,
counterclaim or recoupment which the Company or any other Affiliated Company may
otherwise have against any Participant.

     3.10. WITHHOLDING. All payments with respect to a Participant under this
Plan will be subject to applicable withholding of Federal, state, and local
taxes and other applicable deductions.

     3.11. BENEFITS ON DEATH. In the event of a Participant's death after
becoming entitled to a benefit under the Plan but before complete payment of his
benefit, his benefit shall be paid to his estate.

     3.12. RELEASE AGREEMENT. No Severance Benefit shall be payable to any
Participant unless such Participant executes a release (in a form approved by
the Committee) of all such Participant's claims against the Company and the
Affiliated Companies, to the extent that the basis for such claims arose before
the date that such release is signed by the Participant, and the payment of the
Severance Benefit and other benefits under this Plan shall be subject to the
terms and conditions of such release agreement.

                                    SECTION 4

                                    COMMITTEE

     4.1. DUTIES AND AUTHORITY OF COMMITTEE. Except as otherwise specifically
provided in this Section 4, in controlling and managing the operation and
administration of the Plan, the Committee shall have the following discretionary
authority, powers, rights, and duties in addition to those vested in it
elsewhere in the Plan:

<PAGE>

     (a)  to enforce the Plan in accordance with its terms and with such
          applicable rules of procedure and regulations as may be adopted by the
          Committee;

     (b)  to determine conclusively all questions arising under the Plan,
          including the power to determine the eligibility of employees and the
          rights of Participants to benefits under the Plan, to interpret and
          construe the provisions of the Plan, and to remedy any ambiguities,
          inconsistences or omissions of whatever kind;

     (c)  to employ or utilize agents, attorneys, accountants or other persons
          (who may also be employed by or represent the Company or an Affiliated
          Company) for such purposes as the Committee considers necessary or
          desirable to discharge its duties; and

     (d)  to establish a claims procedure in accordance with section 503 of
          ERISA.

The Committee shall act by a majority of its then members, by meeting or by
writing filed without a meeting.

     4.2. COMMITTEE DECISION FINAL. To the extent permitted by law, any
interpretation of the Plan and any decision on any matter within the discretion
of the Committee made by it in good faith shall be binding on all persons. A
misstatement or other mistake of fact shall be corrected when it becomes known,
and the Committee shall make such adjustment on account thereof as it considers
equitable and practicable.
