                                KATHLEEN SMALLEY


          This Employment Agreement (this "Agreement") is made and entered into
as of the 3rd day of December, 1996 by and between KATHLEEN SMALLEY
("Executive") and CATELLUS DEVELOPMENT CORPORATION, a Delaware corporation, with
its principal office located in San Francisco, California (the "Company").

                                    RECITALS

          The Company desires to secure the services of Executive as Senior Vice
President and General Counsel of the Company and Executive desires to perform
such services for the Company on the terms and conditions hereinafter set forth.

                               A G R E E M E N T:

          NOW, THEREFORE, Executive and the Company hereby agree as follows:

                                       1

                            EMPLOYMENT RELATIONSHIP

1.1  Employment.
     ----------

          (a) The Company hereby employs Executive as Senior Vice President and
General Counsel of the Company, with a term of service to commence on January 1,
1997 (the "Commencement Date").  Executive shall report directly to the Chief
Executive Officer of the Company and shall have such duties as may be prescribed
by the Chief Executive Officer and shall be part of the senior management group
of the Company.  The Company agrees that the duties which may be assigned to
Executive shall be the usual and customary duties of the offices to which she
may from time to time be elected or appointed and shall not be inconsistent with
the provisions of the charter documents of the Company or applicable law (both
as in effect from time to time).

          (b) During the term of this Agreement, Executive shall, except as
described in clause (c) below and subject to the other provisions hereof, devote
her full-time energy and talent to her employment and shall not engage in any
other business activities which would represent a material conflict with her
duties to the Company.  Executive may make and manage personal business
investments of her choice, provided that such activities and services do not
substantially interfere or conflict with the performance of duties hereunder or
create any conflict of interest with such duties.

                                       2
<PAGE>

          (c)  Notwithstanding the foregoing, Executive may devote reasonable
time to activities other than those required under this Agreement, including
supervision of personal investments and activities involving professional,
charitable, educational, political, religious and similar types of
organizations, speaking engagements, memberships of boards of directors of other
organizations and similar activities, provided that Executive shall not serve on
the board of directors of any other business or hold any other position with any
business without the consent of the Chief Executive Officer of the Company.
Company recognizes that Executive serves as a Lecturer at Harvard Law School and
as Chairman of the Visiting Committee of Harvard Law School and agrees that
Executive shall continue to serve in these capacities at her discretion.

          (d) Paid vacations of three weeks (subject to increase in accordance
with the Company's policy with regard to vacation for senior executives) every
12 months shall be permitted and Executive shall be entitled to take such
vacations at such time or times as she shall choose.

          (e) The Executive shall not be required to perform services under this
Agreement during any period that she is disabled.  The Executive shall be
considered "disabled" during any period in which she has a physical or mental
disability which renders her incapable, after reasonable accommodation, of
performing her duties under this Agreement and is eligible to receive income
replacement benefits during such period under a long-term disability plan or
disability insurance provided by the Company.  In the event of a dispute as to
whether Executive is disabled, the Company may refer the same to a licensed

                                       3
<PAGE>

practicing physician of the Company's choice, and the Executive agrees to submit
to such tests and examinations as such physician shall deem appropriate.

1.2  Term.
     ----

          This Agreement shall commence on December 3, 1996, and shall continue
in effect through December 31, 1999 (as such date may be extended in accordance
with this Section 1.2, the "Expiration Date"), subject to the termination
provisions contained in Section 1.7 hereof; provided, however, that (i) unless
                                            --------  -------
the Company gives notice of termination to Executive on or before the December
31 immediately preceding the Expiration Date, the Expiration Date shall be
automatically extended by an additional 12 months to the next succeeding
December 31 and (ii) the Company's obligations under Sections 1.8, 1.12 and 1.13
hereof and Executive's obligations under Section 2.2 hereof shall survive the
termination of this Agreement.

1.3  Base Salary.
     -----------

          Executive shall receive a minimum annual base salary (the "Base
Salary") payable in substantially equal installments no less than twice monthly,
with the first payment to occur on or about January 15, 1997 for services
commencing on the Commencement Date.  The Base Salary shall be reviewed every 12
months by the Chief Executive Officer of the Company and, as a result of that
review, shall be subject to possible increase but not decrease based upon the
attainment of reasonable performance goals as mutually determined

                                       4
<PAGE>

by Executive and the Chief Executive Officer of the Company.  Any increase to
Base Salary which results from that review will be effective on each February
1st by the amount which results from that review and such revised base salary
shall thereafter represent the minimum annual base salary.   Executive's initial
annual Base Salary under this Agreement shall be $231,000.

1.4  Bonuses.
     -------

          (a) Executive shall be eligible to receive an annual bonus (the "Base
Bonus") equal to up to 60% of Base Salary commencing with the year ended
December 31, 1997.  The Base Bonus each year shall be determined on the basis of
the achievement of performance goals negotiated in good faith annually in
advance with Executive by the Chief Executive Officer of the Company on or
before February 28 of each year.  The Base Bonus shall be payable each year no
later than March 31.

          (b) Executive shall be eligible to receive an additional bonus (the
"Additional Bonus") equal to up to 60% of Base Salary commencing with the year
ended December 31, 1997.  The Additional Bonus each year shall be determined on
the basis of the achievement of performance goals negotiated in good faith
annually in advance with Executive by the Chief Executive Officer of the Company
on or before February 28 of each year; provided that the Additional Bonus may
not exceed the Base Bonus in any year.  Such Additional Bonus will be payable
for outstanding service determined on the basis of

                                       5
<PAGE>

reasonably attainable performance goals.  The Additional Bonus shall be payable
each year no later than March 31.

          (c) All bonus payments shall be subject to appropriate withholding
payments deducted therefrom.

1.5  Stock Option.
     ------------

          As of January 1, 1997, Executive will be granted non-qualified stock
options covering an aggregate of 75,000 shares of Common Stock of the Company in
accordance with the Company's existing Amended and Restated Executive Stock
Option Plan and as approved by the Compensation and Benefits Committee of the
Board of Directors of the Company, and the Option Agreement shall be in the form
of Exhibit A attached hereto, which option shall be effective as of the date
hereof.  Such stock option shall be granted with the initial per share exercise
price set at the average closing market price for such Common Stock for the five
trading days prior to the date of this Agreement.  Such option will have a
mandatory withholding feature whereby the Company will withhold such number of
shares at the time of any exercise of the option which will satisfy the
estimated amount of federal and state taxes applicable to the exercise.

          Additional option and other awards, if any, shall be made to Executive
in an equitable manner consistent with Executive's senior position and otherwise
in a manner consistent with the Company's executive compensation policies;
provided, however, the
--------  -------

                                       6
<PAGE>

Company acknowledges that it is contemplated that options for an additional
75,000 shares would be granted to Executive during the 1997 fiscal year if
Executive's performance is of high quality.  The issuance of any shares of
Common Stock of the Company issuable upon exercise of such options shall be
registered under the Securities Act of 1933.

1.6  Place of Performance.
     --------------------

          In connection with her employment hereunder, Executive shall be based
at the San Francisco office of the Company, except for required business travel
for the Company and for any leave of absence.

1.7  Termination of Employment.
     -------------------------

          (a) If at any time during the term of this Agreement, (i) Executive
involuntarily ceases to be an employee of the Company for any reason other than
(A) termination for Cause, (B) disability at a time when Executive is receiving
disability benefits under a long-term disability plan or disability insurance
provided by the Company, (C) death, or (D) normal retirement under the Company's
pension plan or a qualified retirement plan of the Company or (ii) Executive
terminates employment with the Company for Good Reason (as defined below), then
Executive shall be entitled to the benefits provided in Section 1.8 hereof.

                                       7
<PAGE>

          (b) For purposes of this Agreement, the following definitions are set
forth below:

     (i)  Termination by the Company for "Cause" shall mean termination upon the
          willful and continued failure by Executive to substantially perform
          her material duties with the Company (other than any such failure
          resulting from her incapacity due to physical or mental illness) after
          a Notice of Termination as set forth in this Section 1.7(b)(i) is
          delivered to Executive by the Chief Executive Officer of the Company,
          which Notice specifically identifies the manner in which the Board of
          Directors believes that Executive has not substantially performed her
          duties.  For purposes of this Section, no act, or failure to act, on
          Executive's part shall be deemed "willful" unless done, or omitted to
          be done, by Executive not in good faith and without reasonable belief
          that Executive's action or omission was not inconsistent with the best
          interest of the Company.

               Notwithstanding the foregoing, Executive shall not be terminated
          for Cause pursuant to this Section 1.7(b)(i) unless and until
          Executive (A) has received notice of a proposed termination for cause
          with a written explanation of the grounds for such proposed
          termination, (B) Executive has had an opportunity to confer with the
          Chief Executive Officer of the Company, and (C) Executive has had 60
          days after receipt of such notice to cure any alleged non-performance
          of her duties.  If at the end of such sixty-day period the

                                       8
<PAGE>

          nonperformance has not been cured to the satisfaction of the Chief
          Executive Officer, then the Company, upon the determination of the
          Compensation and Benefits Committee of the Board of Directors of the
          Company, may terminate this Agreement for Cause.

     (ii) "Good Reason" shall exist if, without Executive's express written
          consent, any of the following occurs:

          (A) a reduction by the Company in Executive's Base Salary as in effect
     on the date hereof or as the same may be increased from time to time; or

          (B) a demotion from the position or title of Senior Vice President and
     General Counsel of the Company or an assigning of duties to Executive that
     are inconsistent in any substantial respect with or are a reduction in any
     substantial respect from the position, authority, or responsibilities
     associated with the position of Senior Vice President and General Counsel
     of the Company; or

          (C) the failure of the Company to fulfill its obligations under this
     Agreement; or

          (D) the intentional failure of the Company, without Executive's
     consent, to pay to Executive any portion of her salary, earned bonus, or
     other current compensation (if any), or to pay to Executive any portion of
     any installment of

                                       9
<PAGE>

     deferred compensation under any deferred compensation program of the
     Company within ten business days of the date such compensation is due or to
     issue shares of Common Stock of the Company in accordance with the terms of
     stock options granted to Executive upon valid exercise thereof; or

          (E) a relocation of the Company headquarters or requirement for
     Executive to be based anywhere other than within 25 miles from the site of
     the current headquarters of the Company.

     (iii)    For purposes of this Agreement, "Date of Termination" shall mean
               the effective date specified in the Notice of Termination as of
               which Executive's employment terminates (which shall not be less
               than 60 days after the date such Notice of Termination is given)
               or, in the event of termination of employment other than for
               Cause, the date as of which Executive's employment terminates.

          (c) Executive may terminate her employment hereunder at any time by
giving the Company prior written notice, which notice shall be effective not
less than 30 days after it is given to the Company.

                                       10

1.8  Benefits Upon Termination.
     -------------------------

          (a) If, at any time during the term of this Agreement, (i) Executive
involuntarily ceases to be an employee of the Company for any reason other than
(A) termination for Cause, (B) disability at a time when Executive is receiving
disability benefits under a long-term disability plan or disability insurance
provided by the Company, (C) death, or (D) normal retirement under the Company's
pension plan or a qualified retirement plan of the Company or (ii) Executive
terminates employment with the Company for Good Reason (as defined below), then
the amount of benefits payable (as hereinafter described) on account of such
termination shall be equal to the sum of:

     (i)  unpaid salary with respect to any vacation days accrued but not taken
          as of the Date of Termination; and

     (ii) in the event that the termination of employment occurs prior to the
          first anniversary of the Commencement Date, the sum of (1) the number
          of full months remaining in this Agreement, but not to exceed 24,
          multiplied by Executive's monthly Base Salary (determined without
          regard to amounts payable under any bonus program, or other forms of
          extraordinary compensation) as of the Date of Termination; and (2) the
          number of full or partial months remaining in the period commencing on
          the first day following the most recent period in respect of which the
          Base Bonus has been paid and

                                       11
<PAGE>

          ending on the Expiration Date, but not to exceed 24, multiplied by
          $138,600 divided by 12; or

   (iii)  in the event that the termination of employment occurs after the
          first anniversary of the Commencement Date, the sum of (1) the number
          of full months remaining in this Agreement, but not to exceed 24,
          multiplied by the average monthly Base Salary (determined without
          regard to amounts payable under any bonus program, or other forms of
          extraordinary compensation) for the immediately preceding two-year
          period or, if Executive has not served the Company for 24 months, then
          the average monthly Base Salary (determined without regard to amounts
          payable under any bonus program, or other forms of extraordinary
          compensation) for such shorter period; and (2) the number of full or
          partial months remaining in the period commencing on the first day
          following the most recent period in respect of which the Base Bonus
          has been paid and ending on the Expiration Date, but not to exceed 24,
          multiplied by the average monthly Base Bonus and Additional Bonus for
          the immediately preceding two-year period or, if Executive has not
          served the Company for 24 months, then the average monthly Base Bonus
          and Additional Bonus for such shorter period,

provided, however, that the amount of such benefits shall be reduced by any
--------  -------
other benefits provided upon termination of employment to which Executive may be
entitled under any severance agreement with the Company.

                                       12
<PAGE>

          Executive shall not be required to mitigate the amount of any payment
provided for in this Agreement by seeking other employment or otherwise.  The
Company shall not be entitled to set off against the amounts payable to
Executive under this Agreement any amounts owed to the Company by Executive, any
amounts earned by Executive in other employment after termination of her
employment with the Company, or any amounts which might have been earned by
Executive in other employment had she sought such other employment.

          The Company shall pay Executive, no later than the fifth day following
the Date of Termination, a lump sum payment, in cash, equal to the amount due
under Section 1.8(a) hereof; provided, however, Executive may elect any time
                             --------  -------
prior to the Date of Termination to receive the amounts due under Section 1.8(a)
hereof on an installment basis as may be mutually agreed by the Company and
Executive.

          (b) If, at any time during the term of this Agreement, Executive
ceases to be an employee for any reason described in Section 1.8(a) hereof,
during the remainder of the term of this Agreement, Executive shall continue to
be treated as an employee for purposes of the Company's group health and dental
programs, but not for purposes of life, dependent care reimbursement, business
travel accident insurance, or long- or short-term disability programs (except to
the extent Executive is drawing benefits at the time of termination), tax-
qualified retirement plans, or any other employee benefit plan or program of the
Company, and shall receive benefits substantially comparable to those in effect
on the

                                       13
<PAGE>

day before the Date of Termination subject to any reduction or termination of
such benefits similarly affecting all senior management personnel of the
Company.

          (c) If, at any time during the term of this Agreement, Executive
ceases to be an employee for any other reason, then Executive shall be entitled
to the sum of (i) unpaid accrued salary, (ii) unpaid salary with respect to any
vacation days accrued but not taken as of the Date of Termination and (iii) any
bonus or portion thereof to which Executive is entitled under any then effective
bonus plan or program.

1.9  Benefits.
     --------

          Executive shall be entitled to receive employee benefits (including,
but not limited to, pension, medical, insurance and disability benefits) and
perquisites no less favorable than those provided to other senior executives of
the Company (other than the Chief Executive Officer).

          With respect to medical coverage, Executive shall be entitled to
coverage for her family for the term of this Agreement unless Executive is
terminated for Cause in which case coverage shall terminate on the Date of
Termination except for any applicable COBRA coverage.  If, at any time during
the term of this Agreement, Executive involuntarily ceases to be employed by the
Company for any reason other than Termination for Cause or Executive terminates
employment with the Company for Good Reason, then Executive shall

                                       14
<PAGE>

be entitled to medical insurance for the full term of this Agreement as provided
in Section 1.8(b) hereof.

          Executive shall, to the extent available at a commercially reasonable
rate of premium, receive from the Company disability income replacement coverage
under the Company's enhanced disability program benefits which will provide for
replacement of 70% of Base Salary during any period in which Executive is
disabled if the disability arose during the term of this Agreement and prior to
the Date of Termination.  During any period while Executive is disabled, and is
otherwise entitled to receive salary under this Agreement, any salary payments
to Executive shall be reduced by the amount of any benefits paid for the same
period of time pursuant to such disability income replacement coverage.

          Executive also will be entitled to ample office space and appropriate
furniture and all other customary supplies and equipment to fulfill the
requirements of her corporate position as well as to a full-time secretary.

          In addition to the benefits described above, Executive shall be
entitled to participate in a retirement program under the Company's 401-K Plan.

          The Company's current benefit programs are described on Exhibit C
attached hereto and such benefits and the benefits described in this Section 1.9
shall not be materially altered except for across the board modifications
applicable to all Company executives.

                                       15
<PAGE>

1.10 Expenses.
     --------

          Executive shall be entitled to monthly reimbursement for all
reasonable business and business-related entertainment expenses, including an
automobile allowance in an amount not less than $981.05 per month as well as
reimbursement for cellular phone expenses.

1.11 Indemnity.
     ---------

          To the fullest extent permitted by applicable law and the Bylaws of
the Company, as the same now exist or may hereafter be amended, the Company

          2.1  Covenant Against Competition.  Executive agrees that for the
               ----------------------------
period ending on the earlier of the expiration of the term of this Agreement or
when employment is terminated hereunder, Executive will not, except as provided
in Section 1.1(c) hereof, without the prior written approval of the Chair of the
Board of Directors of the Company, directly or indirectly, as owner, partner,
officer or employee, engage in any business which is substantially competitive
with any business then actively conducted by the Company or by any of its
subsidiaries or undertake to consult with or advise any such competitive
business, or otherwise, directly or indirectly, engage in any activity which is
substantially competitive with or in any way adversely and substantially
affecting any activity of the Company or any of its subsidiaries; provided,
                                                                  --------
however, that ownership by Executive of rental homes, of not

<PAGE>

more than 5% of the outstanding shares of stock of any such business listed on
any national stock exchange or quoted on an automated quotation system, or of
not more than 15% of the stock of any such business not so listed or quoted,

Executive may, without further approval, perform services, including but not
limited to consulting, providing legal advice, conducting negotiations, and
directing outside counsel, to Trammell Crow Interests Company d/b/a Crow Family
Holdings ("CFH"), as appropriate to assist in transition as her responsibilities

               ------------------------
payments to be made to Executive hereunder, Executive agrees that:

          (a) During the term of her employment under this Agreement and for a
period of five years thereafter, she will not divulge to anyone, other than to
persons designated by the Company in writing or as may be required by law, any
confidential information concerning the Company or its business as to which
Executive at any time during her employment shall become informed and which is
not then generally known to the public or recognized as standard practice and
shall use reasonable precautions to ensure that such information remains
confidential; and

          (b) During the employment period, upon termination of employment under
this Agreement or at any subsequent time upon request, Executive will return
promptly to the Company as its property, all corporate documents and records in
whatever form they may

                                       19

                               CHANGE OF CONTROL

3.1  Change of Control Payments.
     --------------------------

          In the event that a Change of Control (as defined in Section 3.1(c)
hereof) occurs during the term of this Agreement while Executive is employed by
the Company, Executive shall be entitled to certain payments as follows:

          (a) If, following the execution of an agreement providing for a Change
of Control or within 12 months after the occurrence of the Change of Control,
Executive's employment by the Company or its successor is terminated by the
Company without Cause (as defined in Section 1.7(b)(i) hereof) or by Executive
pursuant to Section 1.7(b)(ii) hereof (relating to Termination for Good Reason),
then Executive shall be entitled to receive from the Company or such successor,
in lieu of, and not in addition to, the amounts otherwise payable to Executive
pursuant to Section 1.8 hereof, a lump sum payment in an amount which is equal
to three times the "base amount" in respect of Executive as defined in Section
280G of the Internal Revenue Code of 1986, as amended (the "Code"), or any
successor to

                                       20
<PAGE>

that provision.  In addition, the stock options described in Section 1.5 hereof
shall become fully vested in such event.

          (b) If any payments under this Agreement, after taking into account
all other payments to which Executive is entitled from the Company, or any
affiliate thereof, are more likely than not to result in a loss of a deduction
to the Company by reason of Section 280G of the Code or any successor provision
to that section, such payments shall be reduced to the extent required to avoid
such loss of deduction.  Executive shall be entitled to select the order in
which payments are to be reduced in accordance with the preceding sentence.

          If reasonably requested by the Company, Executive shall provide
complete compensation and tax data on a timely basis to the Company and to an
accounting or law firm designated by the Company in order to enable the Company
to determine the extent to which payments from the Company and its affiliates
may result in a loss of a deduction.  If Executive incurs fees or expenses in
accumulating such information, the Company shall reimburse Executive for any
reasonable fees and expenses so incurred.

          If Executive and the Company disagree as to whether a payment under
this Agreement is more likely than not to result in the loss of a deduction, the
matter shall be resolved by an opinion of independent tax counsel chosen by the
Company's independent auditors.  The Company shall pay the fees and expenses of
such counsel, and shall make available such information as may be reasonably
requested by such counsel to prepare the opinion.

                                       21
<PAGE>

          If, by reason of the limitations of this Section 3.1(b), the maximum
amount payable to Executive cannot be determined prior to the due date for such
payment, the Company shall pay on the due date the minimum amount which it in
good faith determines to be payable and shall pay the remaining amount, with
interest at a rate compounded semi-annually, equal to 120% of the applicable
Federal rate determined under Section 1274(d) of the Code, as soon as such
remaining amount is determined in accordance with this Section 3.1(b).

          (c) A "Change of Control" of the Company shall be deemed to have
occurred upon the happening of any of the following events:

          (1) the acquisition or holding, other than in or as a result of a
     transaction approved by the Continuing Directors (as defined in clause (b)
     below) of the Company, by any individual, entity or group (within the
     meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
     1934) (an "Acquiror") of beneficial ownership (within the meaning of Rule
     13d-3 promulgated under the Securities Exchange Act of 1934) of 25% or more
     of the combined voting power of the then outstanding shares of Common Stock
     and other stock of the Company entitled to vote generally in the election
     of directors, but excluding for this purpose:

               (i) any such acquisition (or holding) by California Public
          Employees' Retirement System ("CalPERS"), which as of the Effective
          Date holds approximately 40% of the issued and outstanding Common
          Stock of the

                                       22
<PAGE>

          Company, or while CalPERS is the beneficial owner of shares having a
          greater percentage of such combined voting power than the shares held
          by the Acquiror;

               (ii) any such acquisition (or holding) by the Company or any of
          its Subsidiaries, or any employee benefit plan (or related trust) of
          the Company or such Subsidiaries; or

               (iii)  any such acquisition (or holding) by any corporation with
          respect to which, following such acquisition, more than 50% of,
          respectively, the then outstanding shares of common stock of such
          corporation and the combined voting power of the then outstanding
          voting securities of such corporation entitled to vote generally in
          the election of directors is then beneficially owned, directly or
          indirectly, by all or substantially all of the individuals and
          entities who were the beneficial owners, respectively, of the Common
          Stock and other voting securities of the Company immediately prior to
          such acquisition in substantially the same proportion as their
          ownership, immediately prior to such acquisition, of the then
          outstanding shares of Common Stock of the Company and of the combined
          voting power of the then outstanding voting securities of the Company
          entitled to vote generally in the election of directors;

                                       23
<PAGE>

          (2) individuals who, as of the date hereof, constitute the Board of
     Directors (the "Continuing Directors") cease for any reason to constitute
     at least a majority of the Board, provided that any individual becoming a
     director subsequent to the date hereof whose election, or nomination for
     election by the stockholders of Company, was approved by a vote of at least
     a majority of the persons then comprising the Continuing Directors shall be
     considered a Continuing Director, but excluding, for this purpose, any such
     individual whose initial election as a member of the Board is in connection
     with an actual or threatened "election contest" relating to the election of
     the directors of the Company (as such term is used in Rule 14a-11 of
     Regulation 14A promulgated under the Securities Exchange Act of 1934); or

          (3) approval by the stockholders of the Company of (i) a
     reorganization, merger or consolidation of the Company, with respect to
     which in each case all or substantially all of the individuals and entities
     who were the respective beneficial owners of the Common Stock and voting
     securities of the Company immediately prior to such reorganization, merger
     or consolidation do not, following such reorganization, merger or
     consolidation, beneficially own, directly and indirectly, more than 50% of,
     respectively, the then outstanding shares of common stock and the combined
     voting power of the then outstanding voting securities entitled to vote
     generally in the election of directors of the corporation or other entity
     resulting from such reorganization, merger or consolidation, or (ii) a
     complete liquidation or dissolution of the Company, or (iii) the sale or
     other disposition of all or substantially all of the assets of the Company.

                                  (Executive)


          This Award Agreement ("Agreement") is entered into as of

a Delaware corporation ("Catellus"), and

                                Kathleen Smalley

an employee of Catellus (the "Executive").

          The Board of Directors (the "Board") of Catellus wishes to encourage
high levels of performance by individuals who contribute to the success of
Catellus and to further the identity of interests of the Executive with the

          Catellus and the Executive hereby agree as follows:

          1.   NUMBER OF OPTION SHARES.  This Agreement evidences the grant by
Catellus to the Executive, on the terms, conditions and restrictions set forth

                                     75,000

shares of Common Stock (the "Option Shares").

          2.   OPTION PURCHASE PRICE.  Upon exercise, the Executive shall pay to
Catellus $11.05 per Option Share (the "Option Purchase Price").

          3.   OPTION EXPIRATION DATE.  Unless terminated sooner in accordance
with the provisions of the Plan or this Agreement, the right to exercise the

          4.  VESTING RESTRICTIONS.  The Option shall be exercisable in
accordance with the following provisions:

          a.        Except as otherwise provided herein, no portion of the
Option may be exercised for any reason until at least six months have elapsed
following the Date of Grant.

          b.        Subject to the provisions of Section 5 of this Agreement,
the Option shall become exercisable (i) as to the entire number of the Option
Shares on and after the eighth anniversary of the Date of Grant or (ii) if
earlier, in the amounts indicated on and after the dates set forth below (each,
a "Vesting Date") in accordance with the provisions of Section 4c of this
Agreement:

               (A) The Option may be exercised as to up to 25% of the Option
     Shares on and after the first anniversary of the Date of Grant provided the
     conditions specified in Section 4c of this Agreement are met.

               (B) The Option may be exercised as to up to 50% of the Option
     Shares on and after the second anniversary of the Date of Grant provided
     the conditions specified in Section 4c of this Agreement are met.

               (C) The Option may be exercised as to up to 75% of the Option
     Shares on and after the third anniversary of the Date of Grant provided the
     conditions specified in Section 4c of this Agreement are met.

               (D) The Option may be exercised as to up to the entire number of
     the Option Shares on and after the fourth anniversary of the Date of Grant
     provided the conditions specified in Section 4c of this Agreement are met.

          c.        The Option may be exercised as to (i) 25% of the Option
Shares provided the average of the Closing Price (as defined below) of a Common
Share (as defined in the Plan) for any 30 consecutive trading days following the

Common Share for any 30 consecutive trading days following the Date of Grant is

          For purposes of this Section 4c, the term "Closing Price" shall mean,
for any trading day, the closing price of a Common Share on such day (i) on the
New York Stock Exchange ("NYSE"), if the Common Shares are then listed on such
exchange, (ii) if the

<PAGE>

Common Shares are not listed on the NYSE, on the principal national stock
exchange on which the Common Shares are then listed, or (iii) if not listed on
any national stock exchange, as reported by NASDAQ.  If the Common Shares are
not then listed on any national stock exchange or reported by NASDAQ, then the
Closing Price shall be determined in any reasonable manner approved by the
Committee (as defined in the Plan).

          5.   EFFECT OF CERTAIN EVENTS ON VESTING AND EXERCISE.

          a.   TERMINATION OF EMPLOYMENT.

                    (i) General.  In the event of the Executive's termination of
                        -------
          employment for any reason, any portion of the Option that (A) has not
          vested as of such termination, or (B) is vested as of such termination
          or becomes vested as a result of such termination in accordance with
          Section 5a(ii), 5a(iii), or 5b of this Agreement and is not exercised
          within the period specified in Section 5d of this Agreement, shall be
          forfeited.

                    (ii) Termination as a Result of Retirement, Disability or
                         ----------------------------------------------------
          Death.  In the event of the Executive's termination of employment
          -----
          prior to the first anniversary of the Date of Grant by reason of (A)
          retirement at or after age 65, (B) disability (as defined in the
          Plan), or (C) death, a portion of the Option will vest equal to the
          number of Option Shares subject to the Option multiplied by a
          fraction, the numerator of which is the number of months elapsed from
          the Date of Grant and the denominator of which is the number of months
          from the Date of Grant to the final Vesting Date.

                    (iii)  Termination Without Cause or for Good Reason.  In the
                           --------------------------------------------
          event the Executive terminates her employment with Catellus for Good
          Reason, or in the event the Executive involuntarily ceases to be an
          employee of Catellus for any reason other than as a result of
          retirement, disability, death or for Cause, the Option will vest as to
          the entire number of Option Shares (and will be exercisable as to such
          entire number of Option Shares without regard to the conditions of
          Section 4a, 4b or 4c of this Agreement).  "Good Reason" and "Cause"
          shall have the meaning set forth in the Employment Agreement, dated as
          of December 3, 1996, between the Executive and Catellus (the
          "Employment Agreement").

                    (iv) Termination for Cause.  Notwithstanding any other
                         ---------------------
          provision herein, in the event of the Executive's termination of
          employment for Cause (as defined in the Employment Agreement), any
          unexercised portion of the Option, whether vested or unvested, shall
          be immediately forfeited.

                                       3

          b.  CHANGE OF CONTROL.  If, following the execution of an agreement
providing for a Change of Control or within 12 months after the occurrence of a
Change of Control, the Executive's employment by Catellus or its successor is
terminated by Catellus without Cause (as defined in the Employment Agreement) or
by the Executive for Good Reason (as defined in the Employment Agreement), the
Option shall vest immediately as to the entire number of Option Shares (and will
be exercisable as to such entire number of Option Shares without regard to the
conditions of Section 4a, 4b or 4c of this Agreement).  For purposes of this
Agreement, a "Change of Control" of Catellus shall be deemed to have occurred
upon the happening of any of the following events:

               (i) the acquisition or holding, other than in or as a result of a
          transaction approved by the Continuing Directors (as defined in clause
          (ii) below) of Catellus, by any individual, entity or group (within
          the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
          Act of 1934) (an "Acquiror") of beneficial ownership (within the
          meaning of Rule 13d-3 promulgated under the Securities Exchange Act of
          1934) of 25% or more of the combined voting power of the then
          outstanding shares of Common Stock and other stock of Catellus
          entitled to vote generally in the election of directors, but excluding
          for this purpose:

                    (A) any such acquisition (or holding) by the California
          Public Employees' Retirement System ("CalPERS"), which as of the date
          hereof holds approximately 40% of the issued and outstanding Common
          Stock of Catellus, or while CalPERS is the beneficial owner of shares
          having a greater percentage of such combined voting power than the
          shares held by the Acquiror;

                    (B) any such acquisition (or holding) by Catellus or any of
          its subsidiaries, or any employee benefit plan (or related trust) of
          Catellus or such subsidiaries; or

                    (C) any such acquisition (or holding) by any corporation
          with respect to which, following such acquisition, more than 50% of,
          respectively, the then outstanding shares of common stock of such
          corporation and the combined voting power of the then outstanding
          voting securities of such corporation entitled to vote generally in
          the election of directors is then beneficially owned, directly or
          indirectly, by all or substantially all of the individuals and
          entities who were the beneficial owners, respectively, of the Common
          Stock and other voting securities of Catellus immediately prior to
          such acquisition in substantially the same proportion as their
          ownership, immediately prior to such acquisition, of the then
          outstanding shares of Common Stock of Catellus and of the combined
          voting power of the then

                                       4
<PAGE>

          outstanding voting securities of Catellus entitled to vote generally
          in the election of directors;

                    (ii) individuals who, as of the date hereof, constitute the
          Board of Directors (the "Continuing Directors") cease for any reason
          to constitute at least a majority of the Board, provided that any
          individual becoming a director subsequent to the date hereof whose
          election, or nomination for election by the stockholders of Catellus,
          was approved by a vote of at least a majority of the persons then
          comprising the Continuing Directors shall be considered a Continuing
          Director, but excluding, for this purpose, any such individual whose
          initial election as a member of the Board is in connection with an
          actual or threatened "election contest" relating to the election of
          the directors of Catellus (as such term is used in Rule 14a-11 of
          Regulation 14A promulgated under the Securities Exchange Act of 1934);
          or

                    (iii)     approval by the stockholders of Catellus of (A) a
          reorganization, merger or consolidation of Catellus, with respect to
          which in each case all or substantially all of the individuals and
          entities who were the respective beneficial owners of the Common Stock
          or voting securities of Catellus immediately prior to such
          reorganization, merger or consolidation do not, immediately following
          such reorganization, merger or consolidation, beneficially own,
          directly and indirectly, more than 50% of, respectively, the then
          outstanding shares of common stock and the combined voting power of
          the then outstanding voting securities entitled to vote generally in
          the election of directors of the corporation or other entity resulting
          from such reorganization, merger or consolidation, or (B) a complete
          liquidation or dissolution of Catellus, or (C) the sale or other
          disposition of all or substantially all of the assets of Catellus.

          c.   FORFEITURE.  Notwithstanding any other provision herein, any
unexercised portion of the Option, whether vested or unvested, shall be
immediately forfeited if the Executive (i) is employed by a competitor of, or
engaged in any activity in competition with, Catellus without Catellus' consent,
(ii) divulges without Catellus'

consent any secret or confidential information belonging to Catellus, or (iii)
is engaged in any other activities which would constitute grounds for
termination "for cause" (as defined in the Plan).

          d.   EXERCISE PERIOD FOLLOWING TERMINATION OF EMPLOYMENT.

               (i) In the event of the Executive's termination of employment by
          reason of death, any unexercised portion of the Option that is or
          becomes vested upon her death in accordance with Section 5a(ii) of
          this Agreement may be exercised by the Executive's personal
          representative or by the person or

                                       5
<PAGE>

          persons to whom the Option shall have been transferred by
          will or the laws of descent and distribution at any time within one
          year following her death, but in no event after the Expiration Date.

               (ii) In the event of the Executive's termination of employment
          (A) for any reason (1) other than death or (2) other than for Cause
          (as defined in the Employment Agreement) or (B) by reason of the
          resignation of the Executive, any unexercised portion of the Option
          that is or becomes vested upon such termination in accordance with
          Section 5a(ii), 5a(iii), or 5b of this Agreement (unless such
          unexercised portion is forfeited in accordance with Section 5a(iv) or
          5c of this Agreement) may be exercised by the Executive at any time
          within three months following such termination of employment, but in
          no event after the Expiration Date.

          6.   EXERCISE OF OPTION.

               a. All or a portion of the Option may be exercised in accordance
                  with procedures (including requisite holding periods)
                  established from time to time by the Committee. If shares of
                  Common Stock are tendered as payment, such shares of Common
                  Stock shall be valued at their Fair Market Value (as defined
                  in the Plan) on the date of exercise of the Option.

               b. No fractional shares, or cash in lieu thereof, shall be issued
                  under the Option.

               c. As a condition to the grant of the Option, the Executive
                  agrees (i) that Catellus may deduct from any payments of any
                  kind otherwise due to the Executive from Catellus the
                  aggregate amount of any federal, state or local taxes of any
                  kind required by law to be withheld with respect thereto or,
                  if no such payments are due or to become due to the Executive,
                  that the Executive shall pay to Catellus, or make arrangements
                  satisfactory to Catellus regarding the payment to it of, such
                  taxes and (ii) that Catellus or its subsidiaries may withhold
                  from the shares of Common Stock to be issued upon exercise of
                  the Option that number of shares of Common Stock that is
                  equivalent (valuing such shares of Common Stock at their Fair
                  Market Value on the date of exercise of the Option) to the
                  amount of any federal, state or local withholding or other
                  taxes due upon the exercise of the Option. The Committee has
                  approved without further condition the offset of shares of
                  Common Stock for such purposes (subject to any applicable
                  legal limitations) and the Executive irrevocably elects this
                  means of payment of such taxes. If any such taxes should
                  become due after the date of exercise, the Executive must pay,
                  or arrange (to the satisfaction of Catellus) to pay, the
                  amount due.

               d. No shares of Common Stock shall be issued or transferred upon
                  exercise of the Option unless and until all legal requirements
                  applicable to the issuance or

                                       6
<PAGE>

transfer of such Common Stock have been complied with to the satisfaction of the
Committee.

          7.   CHANGE IN CAPITALIZATION.  In the event of a change in the
capitalization of Catellus due to a stock split, stock dividend,
recapitalization, merger, consolidation, combination or similar event, an
appropriate adjustment shall be made in the number of Common Shares subject to
the Plan and the terms of the Option may be adjusted by the Committee to reflect
such change.  Any adjustments pursuant to this Section shall be determined by
the Committee in its sole discretion.

          8.   NO ASSIGNABILITY.  The Option is not assignable or transferable
by the Executive, other than by will, by the laws of descent and distribution or
pursuant to a qualified domestic relations order (as defined by the Internal
Revenue Code of 1986, as amended, or Title I of the Employee Retirement Income
Security Act of 1974, or the rules thereunder), and may be exercised during the
lifetime of the Executive only by the Executive or, if the Executive becomes
disabled, by her legal representative.

          9. OTHER PROVISIONS.

          a.        Nothing in this Agreement or in the Plan shall confer any
right to continue employment with Catellus nor restrict Catellus from
termination of the employment relationship of the Executive at any time in
accordance with the Employment Agreement.

          b.        Nothing in this Agreement or in the Plan shall confer any
rights as a stockholder upon the Executive or any other person entitled to
exercise the Option with respect to any Option Shares covered by the Option
until such time as the Executive or such other person shall have become the
holder of record of such Option Shares.

          c.        The Executive acknowledges receipt of a copy of the Plan,
which is made a part hereof by this reference, and agrees to be bound by the
terms thereof.  In the event of a conflict between the terms of this Agreement
and the Plan, the Plan shall be the controlling document.  Capitalized terms
used but not defined herein shall have the respective meanings ascribed to them
in the Plan.

          d.        The Executive acknowledges that Catellus has the right to
terminate, modify or amend the Plan at any time, but that no such termination,
modification or amendment may, without the Executive's consent, adversely affect
the rights of the Executive under the Option.  The Executive further
acknowledges that the grant of the Option or of any

                                       7
<PAGE>

other option in one year or at one time does not in any way obligate Catellus to
make a grant of an option at any future time or in any given amount.

          e.   In the event that any provision of this Agreement is held to be
invalid, void or unenforceable, the same shall not affect, in any respect
whatsoever, the validity of any other provision of this Agreement.

          f.        The rights and obligations under this Agreement shall inure
to the benefit of, and shall be binding upon, Catellus, the Executive and the
Executive's representatives and beneficiaries.

          g.        Any communication under this Agreement shall be in writing
and addressed to Catellus at 201 Mission Street, San Francisco, California
94105, Attention:  Secretary and to the Executive at the address given beneath
the Executive's signature, or at such other address as either party may
hereafter designate in writing to the other.

          h.        The interpretation, performance and enforcement of the
Option and this Agreement shall be governed by the laws of the State of
California.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first above written.

                              HOUSING ARRANGEMENT

1.   Structure.  The Company's investment in the residence will be structured as
     ---------
an interest-free second participating mortgage.

2.   Terms.
     -----
Investment:
----------

Executive will invest the first $400,000 from any combination of personal funds
and first mortgage loan proceeds; the Company will loan up to $400,000 as an
interest-free second participating mortgage; Executive will invest any
additional funds, from any combination of personal funds and first mortgage loan
proceeds.  The total Company loan amount must be used to acquire a residence
(within the meaning of Section 217 of the Code and the regulations thereunder).
The Company will cooperate reasonably with Executive as necessary to prevent the
Company's interest from affecting first mortgage financing.

Timing:
------
The investment must be made within a reasonable time after Executive's
relocation to San Francisco with the expectation that Executive will enter into
a six-month lease for temporary housing in the San Francisco area.
<PAGE>

Control:
-------

Executive will be the controlling owner of the residence, and the Company will
have no rights of control.  In particular, Executive will have the sole right to
determine (i) when to sell the residence and the sales price, (ii) the proper
level of maintenance, (iii) appropriate security and insurance, and (iv)
improvements.

Participation:
-------------

There will be no current return payable on the Company's loan.  On Final Sale
(as defined below) of the residence, the Company will receive an amount equal to
the product of the net proceeds (after expenses of sale and repayment of the
first mortgage loan) and a fraction the numerator of which is the Company's loan
and the denominator of which is the total basis of the residence (including
subsequent improvements made by Executive).  Executive will have no
responsibility, beyond forwarding the Company's share of proceeds, for the
return to the Company and will be protected from liability for any loss or poor
performance of the investment.

Expenses:
--------

Executive will be responsible for taxes, insurance, and maintenance.  Executive
will determine the appropriate level of insurance and deductible; the Company
will be a named insured to the extent of its interest.  In the event of
earthquake damage, any deductible that exceeds the deductible for any other
damage under the homeowner's policy will be borne first by the Company.

                                       2

Executive Option to Purchase:
----------------------------

Executive will have the option to purchase, at any time, the Company note for an
amount equal to the product of 94% of the Appraised Value and a fraction the
numerator of which is the amount of the Company's loan and the denominator of
which is the total basis of the residence.

Interim Sale:
------------

If Executive sells the residence while employed by the Company and reinvests in
a new residence, the Company will reinvest its share of the proceeds in the new
residence in the same proportion that Executive reinvests her share of the
proceeds in the new residence, provided that Executive must always have at least
$400,000 invested in the new residence.

Termination of Employment:
-------------------------

If Executive's employment is terminated for any reason by either party
("Termination"), the Company may, within 30 days of Termination, demand that a
Final Sale of the residence occur within 24 months of the end of the term of the
Employment Agreement.  If no sale to a third party has occurred by the end of
that period, the Company will have the right to buy Executive's interest in the
residence at the product of 94% of the Appraised Value and a fraction the
numerator of which is the total basis in the residence less the Company loan and
the denominator of which is the total basis in the residence.  If the Company
does not make such a demand or exercise its right to purchase Executive's
interest, the Company's debt will be deemed to have been converted to an
equity investment, but otherwise subject to the remaining conditions of this
agreement, and the next sale of the residence will the Final Sale.

                                      3
<PAGE>

On Final Sale of the residence, the Company will be entitled to retain its share
of the net proceeds with no obligation to reinvest.

Appraised Value:  For purposes hereof, "Appraised Value" means the value
---------------
determined by an MAI appraiser selected by Executive.  The costs of such
appraisal shall be borne by Executive in the event of an exercise of her option
to purchase the Company note and by the Company in the event of an exercise of
its option to require the sale of the residence or to purchase Executive's
interest.
