                              UNIT OPTION AGREEMENT


         This Unit Option Agreement (this "Agreement") is being made and entered
as of February 19, 2002, by and between Crescent Real Estate Equities Limited
Partnership, a Delaware limited partnership (the "Operating Partnership", or
"Employer"), and John C. Goff ("Employee").

                                    RECITALS

         Pursuant to the Employment Agreement dated as of February 19, 2002
("Employment Agreement"), of which this Agreement is attached as an Exhibit,
Employee is employed as the "Chief Executive Officer" of the Operating
Partnership. As a part of the transactions and Compensation Package, as defined
in the Employment Agreement ("Compensation Package"), the Operating Partnership,
acting through Crescent Real Estate Equities, Ltd. (the "General Partner"),
wishes to provide Employee the ability to earn the right to purchase units of
the Operating Partnership in order to encourage Employee to carry out his duties
with vigor.

         Section 4.7.A of the Second Amended and Restated Agreement of Limited
Partnership of the Operating Partnership (as amended, the "Partnership
Agreement"), authorizes the Operating Partnership to adopt a compensation plan
for its employees pursuant to which the Operating Partnership may grant "Limited
Partnership Interests" and "Units" (as defined therein) or options to acquire
Limited Partnership Interests and Units, to one or more of its employees, upon
such terms and conditions as might be deemed necessary or appropriate by the
General Partner. The General Partner believes that this Agreement comes within
the scope of that authorization.

         The right to earn the options described herein is an integral component
of the Compensation Package and is intended to compensate Employee for services
performed by Employee for Operating Partnership from and after February 19, 2002
and during the term of this Employment Agreement and thereafter for the
postemployment obligations of Employee, including confidentiality and
noncompetition, such compensation being expressly contingent on Employee's
fulfillment of these service and other requirements as set forth in the
Employment Agreement. The Compensation Package has been negotiated by Employer
and Employee in lieu of much more significant future cash compensation for the
future services of Employee. Furthermore, Employee's ability to earn the Options
hereunder shall be prospective only and shall be earned only while the
Employment Agreement is in effect.

         Crescent Real Estate Equities Company ("Crescent") and Employer have
previously discussed these matters with Employee, and Employee desires to accept
such employment on such terms.

         As part of the Compensation Package and to induce Employee to make
enthusiastic and productive efforts for the benefit of the Operating
Partnership, the Compensation Committee of the Board of Directors of the General
Partner has recommended that Employee be provided the right to earn unit options
on the terms and subject to the conditions set forth in this Agreement.


<PAGE>


         All capitalized terms used in this Agreement but not defined herein
have the meanings ascribed to those terms in the Partnership Agreement.

         In consideration of the foregoing recitals and mutual promises and
covenants made herein, the parties hereby agree as follows:

         1. OPTION. Subject to the terms and conditions hereof and as part of
the Employee's Compensation Package, the Employee has the right to earn an
option (the "Option") to purchase from the Operating Partnership all or any part
of a total of 1,278,571 Units at a price of $35.02 per Unit. Accordingly, the
number of Units to be associated with Employee's Limited Partnership Interest
when he is admitted to the Operating Partnership as an "Employee Limited
Partner" (as defined in the Partnership Agreement) as a result of having
exercised the Option shall be equal to the number of Units subject to the
Option. Employee's Limited Partnership Interest shall be calculated in
accordance with the provisions of the Partnership Agreement based upon the
number of Units, determined as set forth in the preceding sentence, to be
associated with such Limited Partnership Interest.

         2. CHARACTER OF OPTION. The Option is not an "incentive stock option"
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended (the "Code").

         3. TERM OF OPTION. Subject to earlier termination as provided herein,
the Option shall expire at 6:00 p.m., Fort Worth, Texas time, ten (10) years
after the date on which the Option is granted, and Employee shall have no
further rights under the Option after that date.

         4. VESTING. The earning of the Option and its vesting is contingent on
the continuation of Employee's employment relationship with Crescent pursuant to
the Employment Agreement and is intended to retain Employee as an employee of
the Operating Partnership. The right to exercise options in the future will be
earned by Employee from and after the date of the Employment Agreement and this
Agreement on a year-by-year basis, in accordance with the terms of this
Agreement and in consideration of his future services to be provided by Employee
after the date of the Employment Agreement. Furthermore, Employee's ability to
earn Options shall be prospective only and shall be earned only while his
Employment Agreement is in effect. The Option shall be earned and become vested
according to the following schedule:

After the execution of the Employment Agreement, of which this Unit Option
Agreement forms a part, if Employee ceases to serve as an employee of all of the
Operating Partnership, the


                                      -2-

General Partner and Crescent, further vesting under the Option shall cease.
Notwithstanding the foregoing provisions of this Section, the following special
provisions shall apply:

                  (a) Mergers and Reorganizations. If Crescent or its
         shareholders enter into an agreement to dispose of all or substantially
         all of the assets of Crescent by means of a sale, merger or other
         reorganization, liquidation or otherwise in a transaction in which
         Crescent is not the surviving entity, the Option shall become fully
         vested during the period commencing as of the date agreed to dispose of
         all or substantially all of the assets of Crescent and ending when the
         disposition of assets contemplated by that agreement is consummated or
         the Option otherwise terminates in accordance with its provisions or
         the provisions hereof, whichever occurs first; provided that the Option
         shall not become fully vested under this paragraph on account of any
         agreement of merger or other reorganization when the shareholders of
         Crescent immediately before the consummation of the transaction will
         own at least 50% of the total combined voting power of all classes of
         securities entitled to vote of the surviving entity immediately after
         the consummation of the transaction. The Option shall not become
         immediately exercisable if the transaction contemplated in the
         agreement is a merger or reorganization in which Crescent will survive.

                  (b) Termination of Employment; Change in Control. The Option
         shall become fully vested in the event of either (i) the termination of
         Employee's employment with the Operating Partnership, the General
         Partner and Crescent, for the reason set forth in Section 6(g) of the
         Employment Agreement or (ii) the voluntary resignation by Employee from
         employment with the Operating Partnership, the General Partner and
         Crescent, for Good Reason within 24 months following a Change in
         Control ("Resignation for Good Reason"). For purposes of this
         paragraph:

                           (i) "Good Reason" shall mean (A) a reduction in the
                  amount of Employee's aggregate cash compensation (including
                  base salary and any bonus) payable within any twelve-month
                  period following a Change in Control below the amount of such
                  aggregate cash compensation paid to, or accrued by the General
                  Partner with respect to, Employee in the twelve-month period
                  immediately preceding the change in control; (B) the
                  assignment of Employee to any employment status other than a
                  position reasonably equivalent to a chief executive officer
                  and having duties comparable to those exercised by Employee
                  immediately before the change in duties comparable to those
                  exercised by Employee immediately before the Change in
                  Control, or (C) a geographical relocation or attempted
                  relocation of Employee to an office more than fifty (50) miles
                  distant from Fort Worth, Texas, without Employee's consent.

                           (ii) "Change in Control" shall mean the acquisition
                  of 15% or more of the voting securities of Crescent by any
                  person or by persons acting as a group within the meaning of
                  Section 13(d)(3) of the Exchange Act (other than an
                  acquisition by a person or group meeting the requirements of
                  clauses (i) and (ii) of Rule 13d-1(b)(1) promulgated under the
                  Exchange Act, or by any employee pension benefit plan (within
                  the meaning of Section 3(2) of the Employee


                                      -3-
<PAGE>


                  Retirement Income Security Act of 1974, as amended ("ERISA"))
                  of Crescent or of its subsidiaries, including a trust
                  established pursuant to such plan; provided that no change in
                  control or threatened change in control shall be deemed to
                  have occurred (A) if before the acquisition of, or offer to
                  acquire, 15% or more of the voting securities of Crescent, the
                  full Board of Directors of Crescent (the "Board") has adopted
                  by not less than two-thirds vote a resolution specifically
                  approving such acquisition or offer or (B) from (I) a transfer
                  of Crescent's voting securities by Richard E. Rainwater
                  ("Rainwater") to (a) a member of Rainwater's immediate family
                  (within the meaning of Rule 16a-1(e) of the Exchange Act)
                  either during Rainwater's lifetime or by will or the laws of
                  descent and distribution; (b) any trust as to which Rainwater
                  or a member (or members) of his immediate family (within the
                  meaning of Rule 16a-1(e) of the Exchange Act) is the
                  beneficiary; (c) any trust as to which Rainwater is the
                  settlor with sole power to revoke; (d) any entity over which
                  Rainwater has the power, directly or indirectly, to direct or
                  cause the direction of the management and policies of the
                  entity, whether through the ownership of voting securities, by
                  contract or otherwise; or (e) any charitable trust, foundation
                  or corporation under Section 501(c)(3) of the Code that is
                  funded by Rainwater; or (II) the acquisition of voting
                  securities of Crescent by either (a) Rainwater or (b) a
                  person, trust or other entity described in the foregoing
                  clauses (I)(a)-(e) of this subparagraph. The term "person"
                  shall mean an individual or a corporation, partnership, trust,
                  association, joint venture, pool, syndicate, sole
                  proprietorship, unincorporated organization or any other form
                  of entity not specifically listed herein.

                           (c) Retirement. The Option shall become fully vested
                  in the event of Employee's Retirement. "Retirement" shall be
                  deemed to occur if Employee's employment terminates on or
                  after the date on which he attains age 70.

                           (d) Death or Disability. The Option shall become
                  fully vested in the event of Employee's death or Disability.
                  "Disability" shall mean the absence of the Employee from the
                  Employee's duties with the Operating Partnership, General
                  Partner and Crescent on a full-time basis for 180 consecutive
                  business days as a result of incapacity due to mental or
                  physical illness or injury which renders Employee unable to
                  perform all of the material and substantial duties of his
                  employment, as it existed immediately prior to such illness or
                  injury, and which is reasonably expected to be permanent.

         5. METHOD OF EXERCISE. The Option shall be exercisable only to the
extent that it is vested. The Option may not be exercised for a fraction of a
Unit. The purchase price of any Units purchased shall be paid at the time of
exercise of the Option either (i) in cash, (ii) by certified or cashier's check,
(iii) by delivery to the Operating Partnership (either directly or by
attestation) of Units already owned (for at least six months) by Employee,
valued at the then Fair Market Value, (iv) by a promissory note, such note to
provide for the right to repay the note partially or wholly with Units and to
bear interest at a rate at least equal to the applicable Federal rate (within
the meaning of Section 7872(f)(2) of the Code), and otherwise to have such terms
as shall be specified by the Committee, or (v) by delivery of a copy of
irrevocable instructions from Employee to a broker or dealer, reasonably
acceptable to the General Partner, to sell certain of


                                      -4-
<PAGE>


the common shares of beneficial interest, par value $.01 per share, of Crescent
("Shares") acquired upon exercise of the Option and the exercise of "Exchange
Rights" (as defined in the Partnership Agreement) or to pledge them as
collateral for a loan and promptly deliver to Crescent the amount of sale or
loan proceeds necessary to pay such purchase price. Subject to the limitations
in clause (iv), the Committee may amend or revise the terms of a note issued
pursuant to clause (iv), or replace it with a new note, provided that no such
amendment or revision that could have an adverse effect on Employee shall be
effective without his consent. If any portion of the purchase price or a note
given at the time of exercise is paid in Units, those Units shall be valued at
the then Fair Market Value. "Fair Market Value" shall mean such value as will be
determined by the General Partner on the basis of such factors as it deems
appropriate. The Option shall be deemed to be exercised when written notice of
exercise has been received by the Operating Partnership at its principal office
from the person entitled to exercise the Option and payment for the Units with
respect to which the Option is exercised has been received by the Operating
Partnership in accordance with this Section 5.

         6. TRANSFERABILITY. The Option shall not be transferable other than by
will or by the laws of descent and distribution and may be exercised during the
lifetime of Employee only by Employee or by his legally authorized
representative.

         7. COMPLIANCE WITH SECURITIES LAWS. Units shall not be issued upon the
exercise of the Option unless the issuance and delivery of the Units (and the
exercise of the Option) complies with all relevant provisions of federal and
state law, including without limitation the Securities Act of 1933, as amended,
the rules and regulations promulgated thereunder and the requirements of any
stock exchange upon which the Shares might then be listed, and shall be further
subject to the approval of counsel for Crescent with respect to such compliance.
The General Partner may also require Employee to furnish evidence satisfactory
to the General Partner and Crescent, including, without limitation, a written
and signed representation letter and consent to be bound by any transfer
restrictions imposed by law, legend, condition or otherwise, and a
representation that the Units are being acquired only for investment and without
any present intention to sell or distribute the Units in violation of any
federal or state law, rule or regulation. Further, Employee shall consent to the
imposition of a legend on the certificate representing the Units issued upon the
exercise of the Option and Shares issued upon the exchange therefore restricting
their transferability as required by law or by this Section.

         8. COMPLIANCE WITH PARTNERSHIP AGREEMENT. All Units and Exchange Rights
issued upon the exercise of the Option are governed by, and subject to each of
the terms and conditions of, the Partnership Agreement. Upon exercising the
Option, Employee shall be admitted to the Operating Partnership as an Employee
Limited Partner pursuant to Section 4.7 of the Partnership Agreement in
accordance with the terms of the Partnership Agreement and the procedures
established by the General Partner for the admission of an Employee Limited
Partner thereunder, and shall be deemed to have accepted and agreed to be bound
by all the terms and conditions of the Partnership Agreement. The General
Partner, in its sole and absolute discretion, may make the exercise of the
Option subject to such further terms and conditions, including, without
limitation, such additional terms and conditions for admission to the Operating
Partnership or the exercise of Exchange Rights, as the General Partner may deem
necessary, advisable or appropriate at the time of the exercise. Such additional
terms and


                                      -5-
<PAGE>


conditions may be set forth in resolutions adopted by the Board of Directors of
the General Partner and/or Crescent, or in such other manner or document as the
General Partner, in its sole and absolute discretion, deems necessary, advisable
or appropriate.

         9. EXCHANGE RIGHTS. The Units issued upon the exercise of the Option
shall have the Exchange Rights associated with the Limited Partnership Interest
represented by the Units. Employee acknowledges that, upon exercise of the
Exchange Rights, Crescent pursuant to the Partnership Agreement has the option
in its sole discretion to deliver cash or Shares in exchange for Units as to
which Employee exercises Exchange Rights. Crescent will deliver cash in exchange
for the Units as to which the Employee has exercised Exchange Rights in lieu of
the issuance or delivery of any certificate for the Shares upon the exercise of
Exchange Rights unless:

                  (a) the shareholders of Crescent have approved the Exchange
         Rights applicable to the Units that may be acquired upon exercise of
         the Option;

                  (b) the Shares have been admitted to listing on all stock
         exchanges on which Shares are then listed, unless the General Partner
         determines in its sole discretion that such listing is neither
         necessary nor advisable;

                  (c) all required registration or other qualification of the
         sale of the Shares under any federal or state law or under the rulings
         or regulations of the Securities and Exchange Commission or any other
         governmental regulatory body that the General Partner in its sole
         discretion deems necessary or advisable has been obtained; and

                  (d) all approvals or other clearances from federal or state
         governmental agency that the General Partner in its sole discretion
         determines to be necessary or advisable have been obtained.

         10. RESERVATION OF SHARES. Crescent shall at all times reserve and keep
available such number of Shares as might be necessary to satisfy the
requirements of Section 10 hereof and the number of Units as to which the Option
is granted. In addition, Crescent shall from time to time, as is necessary to
accomplish the purposes of this Agreement, use its best efforts to obtain from
any regulatory agency having jurisdiction any requisite authority necessary to
issue Shares upon the exercise of Exchange Rights related to the Units as to
which the Option is granted. The inability of Crescent to obtain from any
regulatory agency having jurisdiction the authority deemed by Crescent's counsel
to be necessary for the lawful issuance of any Shares shall relieve Crescent of
any liability in respect of the nonissuance of Shares as to which the requisite
authority has not been obtained.

         11. RESTRICTIONS ON CORRESPONDING SECURITIES AND ASSETS. As a condition
to the grant of this Option, Employee covenants and agrees to execute a Second
Amended and Restated Promissory Note as well as an Amended and Restated Security
Agreement and Financing Statement, in the form previously agreed, dated as of
even date herewith, in order to provide that 60% of the excess of (i) any
proceeds received upon sale of any Share acquired upon the exercise of the
Option and exchange of Units into Shares over (ii) $17.51 (the portion of the
exercise


                                      -6-
<PAGE>


price of a Unit attributable to one Share) shall be used to repay, including
prepayment, certain obligations between Goff and the Company or its affiliates
("Company Notes"). If cash is received instead of Shares upon the exercise of
Exchange Rights with respect to Units acquired pursuant to exercise of the
Option, then 60% of the excess of (i) any cash received upon the exchange of
Units for cash over (ii) $35.02 shall be used to repay, including prepayment,
any Company Notes.

         12. TAX WITHHOLDING.

                  (a) Condition Precedent. The issuance of Units upon the
         exercise of the Option is subject to the condition that if at any time
         the General Partner determines, in its discretion, that the
         satisfaction of withholding tax or other withholding liabilities under
         any federal, state or local law is necessary or desirable as a
         condition of, or in connection with such issuances, then the issuances
         shall not be effective unless the withholding has been effected or
         obtained in a manner acceptable to the General Partner.

                  (b) Manner of Satisfying Withholding Obligation. If Employee
         is required to pay to the Operating Partnership an amount required to
         be withheld under applicable income tax laws in connection with the
         exercise of the Option, such payment may be made (i) in cash, (ii) by
         check, (iii) by delivery to the Operating Partnership or the General
         Partner of Units already owned by Employee having a Fair Market Value
         on the date the amount of tax to be withheld is to be determined (the
         "Tax Date") equal to the amount required to be withheld, (iv) through
         the withholding by the Operating Partnership ("Partnership
         Withholding") of a portion of the Units acquired upon the exercise of
         the Option or (v) in any other form of valid consideration, as
         permitted by the General Partner in its discretion.

         13. ADMINISTRATION.

                  (a) General Partner. This Agreement shall be administered by
         the General Partner. Subject to the provisions of this Agreement, the
         General Partner shall have the discretion and authority to prescribe,
         amend and rescind any reasonable rules and regulations necessary or
         appropriate for the administration of this Agreement; to modify or
         amend this Agreement or waive any conditions or restrictions applicable
         to the Option (or the exercise thereof); and, to make all other
         determinations as advisable for the administration of this Agreement;
         provided, however, that any amendment or modification of this Agreement
         shall require the consent of the Employee which may be given or
         withheld in his discretion, with any such amendment to be made
         effective only by an instrument in writing signed by both the Operating
         Partnership and Employee.

                  (b) Committee. The General Partner may delegate its authority
         under paragraph (a) of this Section to a Committee appointed by the
         General Partner, in which case all references herein to the General
         Partner that relate to the administration of this Agreement shall be
         deemed to be references to the Committee. As used herein, "Committee"
         shall mean a committee consisting of two or more members of the Board.
         A majority of the members of the Committee shall constitute a quorum,
         and any action


                                      -7-
<PAGE>


         taken by a majority present at a meeting at which a quorum is present
         or any action taken without a meeting evidenced by a writing executed
         by all members of the Committee shall constitute the action of the
         Committee. Meetings of the Committee may take place by telephone
         conference call.

                  (c) Assistance. The Operating Partnership shall supply full
         and timely information to the General Partner and/or the Committee on
         all matters relating to Employee, his employment, death, retirement,
         Disability or other termination of employment, and such other pertinent
         facts as the General Partner or the Committee might require. The
         Operating Partnership shall furnish the General Partner and the
         Committee with such clerical and other assistance as is necessary to
         the performance of its duties, and Employee as the Chief Executive
         Officer of the Operating Partnership, shall in now way interfere with
         or restrain the ability of the Operating Partnership in this regard.

         14. ACKNOWLEDGEMENTS BY EMPLOYEE. Employee acknowledges he may be
removed as an officer of the Operating Partnership, the General Partner or
Crescent in accordance with applicable law; if such event occurs while the
Option is not fully vested, Section 4 herein shall govern the full or partial
forfeiture of the Option. Employee agrees that no duty of good faith or fair
dealing shall be read into this Agreement against the Operating Partnership, the
General Partner or Crescent. Employee understands and intends that this
Agreement does not create a partnership or joint venture between Employee and
the Operating Partnership.

         15. INTEGRATION; ENTIRE AGREEMENT. The parties agree that this
Agreement serves as an integral part of the Employment Agreement between
Employee and the Operating Partnership and the Compensation Package contemplated
therein and that the rights under this Agreement form a significant portion of
the consideration for the Employment Agreement between Employer and Employee. As
a result, the terms of this Agreement shall be construed in conjunction with and
consistent with the Employment Agreement and any ambiguities resolved by taking
into account the intent of the parties that the Employment Agreement and the
documents attached thereto, including this Agreement, are part of an integrated
employment and compensation arrangement.

         16. CHOICE OF FORUM. The parties hereto agree that should any suit,
action or proceeding arising out of this Unit Option Agreement be instituted by
any party hereto (other than a suit, action or proceeding to enforce or realize
upon any final court judgment arising out of this Unit Option Agreement), such
suit, action or proceeding shall be instituted only in a state or federal court
in Tarrant County, Texas. Each of the parties hereto consents to the in personam
jurisdiction of any such state or federal court in Tarrant County, Texas and
waives any objection to the venue of any suit, action or proceeding. The parties
recognize that courts outside Tarrant County, Texas may also have jurisdiction
over suits, actions or proceedings arising out of this Unit Option Agreement,
and in the event that any party hereto shall institute a proceeding involving
this Unit Option Agreement in a jurisdiction outside Tarrant County, Texas, the
party instituting such proceeding shall indemnify any other party hereto for any
losses and expenses that may result from the breach of the foregoing covenant to
institute such proceeding only in a state or federal court in Tarrant County,
Texas, including without limitation or additional

expenses incurred as a result of litigating in another jurisdiction, such as
reasonable fees and expenses of local counsel and travel and lodging expenses
for parties, witnesses, experts and support personnel.

         17. MISCELLANEOUS. This Agreement shall be construed in accordance with
the laws of the State of Delaware, and shall be binding upon and inure to the
benefit of any successor or assign of the Operating Partnership and any
executor, administrator, trustee, guarantor or other legal representative of
Employee. Headings of Sections and paragraphs of this Agreement are inserted for
convenience of reference and constitute no part of this Agreement. The Operating
Partnership shall request Crescent to furnish to Employee copies of annual
reports, proxy statements and all other reports sent to Crescent's shareholders
and, upon Employee's written request, a copy of its most recent Annual Report on
Form 10-K and each quarterly report to shareholders issued since the end of
Crescent's most recent fiscal year. If the outstanding Units or Shares are
increased, decreased, changed into or exchanged for a different number or kind
of units, shares or securities through merger, consolidation, combination,
exchange, other reorganization, recapitalization, reclassification, dividend,
split or reverse split, an appropriate and proportionate adjustment shall be
made to the Option. Any such adjustment shall be made without change in the
aggregate purchase price applicable to the unexercised portion of the Option,
but with a corresponding adjustment in the price for each Unit purchasable under
the Option. The foregoing adjustments and the manner of application of the
foregoing provisions shall be determined solely by the General Partner, and any
such adjustment may provide for the elimination of fractional share interests.

         Executed as of the day and year first written above.
