                       liquidation of the Partnership pursuant to the terms of
                       this Agreement, including, without limitation, a
                       certificate of cancellation; and (d) all instruments
                       relating to the Capital Contribution of any Partner or

                       absolute discretion of the General Partner, to make,
                       evidence, give, confirm or ratify any vote, consent,
                       approval, agreement or other action which is made or

                       terms of this Agreement or appropriate or necessary, in
                       the sole discretion of the General Partner, to effectuate
                       the terms or intent of this Agreement.

Nothing contained herein shall be construed as authorizing the General Partner
to amend this Agreement except in accordance with Article 14 hereof or as may be
otherwise expressly provided for in this Agreement.

               B.      The foregoing power of attorney is hereby declared to be
irrevocable and a power coupled with an interest, in recognition of the fact
that each of the Partners will be relying upon the power of the General Partner
to act as contemplated by this Agreement in any filing or other action by it on
behalf of the Partnership, and it shall survive and not be affected by the
subsequent Incapacity of any Limited Partner or the transfer of all or any
portion of such Limited Partner's Partnership Interest and shall extend to such
Limited Partner's heirs, successors, assigns and personal representatives. Each
such Limited Partner hereby agrees to be bound by any representation made by the
General Partner, acting in good faith pursuant to such power of attorney; and
each such Limited Partner hereby waives any and all defenses which may be
available to contest, negate or disaffirm the action of the General Partner,
taken in good faith under such power of attorney. Each Limited Partner shall
execute and deliver to the General Partner or the Liquidator, within fifteen
(15) days after receipt of the General Partner's or Liquidator's request
therefor, such further designation, powers of attorney and other instruments as
the General Partner or the



                                      -20-

Liquidator, as the case may be, deems necessary to effectuate this Agreement and
the purposes of the Partnership.

         Section 2.5  Term

         The term of the Partnership commenced on February 9, 1994, and shall
continue until December 31, 2093, unless it is dissolved sooner pursuant to the
provisions of Article 13 or as otherwise provided by law.

                                 ARTICLE III
                                   PURPOSE

         Section 3.1  Purpose and Business

         The purpose and nature of the business to be conducted by the
Partnership is (i) to conduct any business that may be lawfully conducted by a
limited partnership organized pursuant to the Act, including, without
limitation, to acquire, hold, own, develop, construct, improve, maintain,
operate, sell, lease, transfer, encumber, convey, exchange, and otherwise
dispose of or deal with real and personal property of all kinds; to acquire
stock ownership interests in and to exercise all of the powers of a stockholder
in the Subsidiary Development Corporations and the Management Company; (ii) to
enter into any partnership, joint venture or other similar arrangement to engage
in any of the foregoing or the ownership of interests in any entity engaged in
any of the foregoing; and to exercise all of the powers of an owner in any such
entity; and (iii) to do anything necessary, appropriate, proper, advisable,
desirable, convenient or incidental to the foregoing; provided, however, that
such business shall be limited to and conducted in such a manner as to permit
Crescent Equities at all times to qualify as a REIT, unless Crescent Equities
voluntarily terminates its REIT status pursuant to its Declaration of Trust. In
connection with the foregoing, and without limiting Crescent Equities' right in
its sole discretion to cease qualifying as a REIT, the Partners acknowledge that
Crescent Equities' current status as a REIT inures to the benefit of all the
Partners and not solely the Crescent Group.

         Section 3.2  Powers

         Subject to all of the terms, covenants, conditions and limitations
contained in this Agreement and any other agreement entered into by the
Partnership, the Partnership shall have full power and authority to do any and
all acts and things necessary, appropriate, proper, advisable, desirable,
incidental to or convenient for the furtherance and accomplishment of the
purposes and business described herein and for the protection and benefit of the
Partnership, including, without limitation, full power and authority, directly
or through its ownership interest in other entities, to enter into, perform and
carry out contracts of any kind, borrow money and issue evidences of
indebtedness, whether or not secured by mortgage, deed of trust, pledge or other
lien, acquire and develop real property, and lease, sell, transfer or otherwise
dispose of real property; provided, however, that the Partnership shall not
take, or refrain from taking, any action which, in the judgment of General
Partner, in its sole and absolute discretion, (i) could adversely affect the
ability of Crescent Equities to achieve or maintain qualification as a REIT,
(ii) could subject Crescent



                                      -21-
<PAGE>   27

Equities to any additional taxes under Section 857 or Section 4981 of the Code,
or (iii) could violate any law or regulation of any governmental body or agency
having jurisdiction over Crescent Equities or its securities, unless such action
(or inaction) shall have been specifically consented to by the General Partner
in writing.

                                   ARTICLE IV
                              CAPITAL CONTRIBUTIONS

         Section 4.1  Capital Contributions of the Partners

               A.     Each Partner listed in Exhibit A has previously made a
Capital Contribution to the Partnership as specified in the First Amended
Agreement or in the Recitals portion of this Agreement, as the case may be, in
exchange for its Partnership Units and Partnership Interest set forth in
Exhibit A.

               B.     The Partners shall own Partnership Units in the amounts
set forth in Exhibit A and shall have Partnership Interests in the Partnership
as set forth in Exhibit A, which Partnership Units and Partnership Interests
shall be adjusted in Exhibit A from time to time by the General Partner to the
extent necessary to reflect accurately the exercise of Exchange Rights, Capital
Contributions, transfers of Partnership Interests, admissions of Additional
Limited Partners or Employee Limited Partners, or similar events. Except as
provided in Section 10.5, or as a result of directly paying any Partnership
debt, the Partners shall have no obligation to make any additional Capital
Contributions or loans to the Partnership.

               C.     The interest of each Limited Partner in Partnership Units
may be evidenced by one or more certificates in such form as the General Partner
may from time to time prescribe. Upon surrender to the General Partner of a
certificate evidencing the ownership of Partnership Units accompanied by proper
evidence of authority to transfer, the General Partner shall cancel the old
certificate, issue a new certificate to the Person entitled thereto and record
the transaction upon its books. The transfer of Partnership Units may be
effectuated only in connection with a transfer of a Limited Partnership Interest
pursuant to the terms of Section 8.6 or Article 11 hereof. The General Partner
may issue a new certificate or certificates in place of any certificate or
certificates previously issued, which previously-issued certificate or
certificates are alleged to have been lost, stolen or destroyed, upon the making
of an affidavit of that fact by the owner claiming the certificate or
certificates to be lost, stolen or destroyed. When issuing such new certificate
or certificates, the General Partner may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificate or certificates, or its legal representative, to give the
Partnership a bond in such sum as the General Partner may direct as indemnity
against any claim that may be made against the Partnership with respect to the
certificate or certificates alleged to have been lost, stolen or destroyed.

         Section 4.2  Additional Funding

               A.     If the General Partner determines that it is in the best
interests of the Partnership to provide for additional Partnership funds
("Additional Funds") for any Partnership purpose in excess of any other funds
determined by the General Partner to be available to the



                                      -22-
<PAGE>   28

Partnership, the General Partner (i) may cause the Partnership to obtain such
funds from outside borrowings, (ii) may cause the Partnership to obtain such
funds by the admission of Additional Limited Partners pursuant to Section 4.3
hereof, or (iii) may elect to have Crescent Equities provide such Additional
Funds to the Partnership. On any date that Crescent Equities provides Additional
Funds to the Partnership (the "Funding Date"):


               (1)     to the extent the General Partner elects to borrow all or
                       any portion of the Additional Funds through a Funding
                       Loan, the General Partner shall cause Crescent Equities
                       to lend (the "Crescent Loan") to the Partnership the
                       Funding Loan Proceeds on comparable terms and conditions,
                       including interest rate, repayment schedule and costs and
                       expenses, as shall be applicable with respect to or
                       incurred in connection with the Funding Loan; or

               (2)     to the extent the General Partner does not elect to
                       borrow all or any portion of the Additional Funds by
                       entering into a Funding Loan, the General Partner shall
                       cause Crescent Equities to contribute to the Partnership
                       as an additional Capital Contribution the amount of the
                       Additional Funds not loaned to the Partnership as a
                       Crescent Loan (the "Contributed Funds") (hereinafter,
                       each Funding Date on which Crescent Equities so
                       contributes Contributed Funds pursuant to this
                       subparagraph (2) is referred to as an "Adjustment Date").
                       The Crescent Group may raise such Contributed Funds
                       through a private placement or public offering of REIT
                       Shares or otherwise. The Partnership shall assume or pay
                       the expenses, including any applicable underwriting
                       discounts incurred by the Crescent Group in connection
                       with raising such Contributed Funds through a private
                       placement or public offering of its securities or
                       otherwise (i.e., Crescent Equities shall be treated as
                       contributing to the Partnership as Contributed Funds the
                       gross amount of funds raised, and the Partnership shall
                       be charged with the cost of raising such funds, with such
                       cost allocated to all of the Partners in accordance with
                       Article VI of the Agreement).

              B.       Effective on each Adjustment Date, Crescent Equities
shall receive an additional Partnership Interest (and the Partnership Interest
of each Limited Partner other than Crescent Equities shall be reduced) such
that:

               (1)     the Partnership Interest of each Limited Partner not
owning Partnership Units (other than Crescent Equities) shall be equal to a
fraction, the numerator of which is equal to the Deemed Partnership Interest
Value of such Limited Partner (computed as of the Business Day immediately
preceding the Adjustment Date) and the denominator of which is equal to the sum
of (i) the Deemed Value of the Partnership (computed as of the Business Day
immediately preceding the Adjustment Date) and (ii) the amount of Contributed
Funds contributed by Crescent Equities on such Adjustment Date;

               (2)    the combined Partnership Interest of Crescent Equities
and the General Partner shall be equal to a fraction, the numerator of which is
equal to the sum of (i) the



                                      -23-
<PAGE>   29

combined Deemed Partnership Interest Value of Crescent Equities and the General
Partner (computed as of the Business Day immediately preceding the Adjustment
Date) and (ii) the amount of the Contributed Funds contributed by Crescent
Equities on such Adjustment Date and the denominator of which is equal to the
sum of (x) the Deemed Value of the Partnership (computed as of the Business Day
immediately preceding the Adjustment Date) and (y) the amount of the Contributed
Funds contributed by Crescent Equities on such Adjustment Date. The Partnership
Interest of the General Partner shall remain one percent (1%), and the
Partnership Interest of Crescent Equities shall be equal to the combined
Partnership Interest determined in clause (2) of the preceding sentence, reduced
by one percentage point (1%); and

               (3)    the Partnership Interest of each Limited Partner owning
Partnership Units shall be equal to the product of the following: (i) the
difference obtained from subtracting (x) the sum of the combined Partnership
Interest of Crescent Equities and the General Partner as calculated in Section
4.2.B(2) hereof, plus the aggregate Non-Unitholder Partnership Interests as
calculated in Section 4.2.B(1) hereof, from (y) one hundred percent (100%), and
(ii) a fraction, the numerator of which is equal to the number of Partnership
Units held by such Limited Partner on such Adjustment Date, and the denominator
of which is equal to the total number of Partnership Units held by all Limited
Partners on such Adjustment Date.

         The General Partner shall be authorized on behalf of each of the
Partners to amend this Agreement to reflect the increase in the Partnership
Interest of Crescent Equities and the corresponding reduction of the Partnership
Interests of the other Limited Partners in accordance with the provisions of
this Section 4.2. The number of Partnership Units owned by the Limited Partners
and Assignees shall not be decreased in connection with any additional
contribution of funds to the Partnership by Crescent Equities pursuant to this
Section 4.2. Notwithstanding anything to the contrary contained in this
Agreement, for purposes of calculating the "Deemed Value of the Partnership" and
the "Deemed Partnership Interest Value" under this Section 4.2.B with respect to
cash amounts raised by Crescent in a private placement or public offering of
REIT Shares and contributed to the Partnership as Contributed Funds, the "Value"
of a REIT Share shall be the gross offering price (prior to deduction of any
expenses, including without limitation selling commissions or underwriting
discounts) per REIT Share sold in the private placement or public offering.

         C.    The Partners hereby acknowledge and agree that any Additional
Funds provided by the Crescent Group (through Crescent Equities) to the
Partnership pursuant to this Section 4.2 may be in the form of real property or
an interest therein rather than cash. In the event that real property or an
interest therein is contributed by Crescent Equities to the Partnership pursuant
to this Section 4.2:

               (1)    to the extent that the consideration given in exchange for
such real property or interest therein is in the form of indebtedness, Crescent
Equities shall be deemed to have made a Crescent Loan to the Partnership
pursuant to Section 4.2.A(1) hereof in an amount equal to the amount of such
indebtedness; and



                                      -24-
<PAGE>   30

               (2)    to the extent that the consideration given in exchange for
such real property or interest therein is in the form of cash or REIT Shares,
(i) Crescent Equities shall be deemed to have contributed Contributed Funds to
the Partnership pursuant to Section 4.2.A(2) hereof in an amount equal to the
amount of cash or the Value (computed as of the Business Day immediately
preceding the date on which such real property or interest therein is
contributed to the Partnership) of the REIT Shares given as consideration, and
(ii) the Partnership Interests of the Limited Partners shall be adjusted as set
forth in Section 4.2.B hereof.

To the extent that the consideration given for such real property or interest
therein is New Securities, the provisions of Section 8.7.C hereof shall apply to
the contribution of the real property or interest therein by Crescent Equities
to the Partnership.

         Section 4.3  Issuance of Additional Partnership Interests

         At any time after the date hereof, without the consent of any Partner,
but subject to the provisions of Section 12.2 hereof, the General Partner may,
upon its determination that the issuance of additional Partnership Interests is
in the best interests of the Partnership, cause the Partnership to issue
Partnership Interests to and admit as a limited partner in the Partnership, any
Person (the "Additional Limited Partner") in exchange for the contribution by
such Person of cash and/or property in such amounts as is determined appropriate
by the General Partner to further the purposes of the Partnership under Section
3.1 hereof. In the event that an Additional Limited Partner is admitted to the
Partnership pursuant to this Section 4.3:

               (1)     if the Additional Limited Partner does not receive any
                       Partnership Units in connection with the receipt of his
                       or its Partnership Interest, the Partnership Interest of
                       such Additional Limited Partner shall be equal to a
                       fraction, the numerator of which is equal to the total
                       dollar amount of the cash contributed and/or the Net
                       Asset Value of the property contributed by the Additional
                       Limited Partner as of the date of contribution to the
                       Partnership (the "Contribution Date") and the denominator
                       of which is equal to the sum of (i) the Deemed Value of
                       the Partnership (computed as of the Business Day
                       immediately preceding the Contribution Date) and (ii) the
                       total dollar amount of the cash contributed and/or the
                       Net Asset Value of the property contributed by the
                       Additional Partner as of the Contribution Date;

               (2)     the Partnership Interest of Crescent Equities shall be
                       reduced, as of the Contribution Date, such that the
                       combined Partnership Interest of Crescent Equities and
                       the General Partner shall be equal to a fraction, the
                       numerator of which is equal to the combined Deemed
                       Partnership Interest Value of Crescent Equities and the
                       General Partner (computed as of the Business Day
                       immediately preceding the Contribution Date) and the
                       denominator of which is equal to the sum of (i) the
                       Deemed Value of the Partnership (computed as of the
                       Business Day immediately preceding the Contribution Date)
                       and (ii) the total dollar amount of the cash contributed
                       and/or the Net Asset Value of the property contributed by
                       the Additional Limited Partner as of

                       the Contribution Date (with the Partnership Interest of
                       the General Partner remaining at one percent (1%), and
                       the Partnership Interest of Crescent Equities equal to
                       the combined Partnership Interest determined above in
                       this Section 4.3(2), reduced by one percentage point
                       (1%));

               (3)     the Partnership Interest of each existing Limited Partner
                       not owning Partnership Units (other than Crescent
                       Equities) shall be reduced, as of the Contribution Date,
                       such that the Partnership Interest of each such Limited
                       Partner shall be equal to a fraction, the numerator of
                       which is equal to the Deemed Partnership Interest Value
                       of such Limited Partner (computed as of the Business Day
                       immediately preceding the Contribution Date) and the
                       denominator of which is equal to the sum of (i) the
                       Deemed Value of the Partnership (computed as of the
                       Business Day immediately preceding the Contribution Date)
                       and (ii) the total dollar amount of the cash contributed
                       and/or the Net Asset Value of the property contributed by
                       the Additional Limited Partner as of the Contribution
                       Date; and

               (4)     The Partnership Interest of each existing Limited Partner
                       owning Partnership Units and of the Additional Limited
                       Partner, if such Additional Partner receives Partnership
                       Units in connection with the receipt of his or its
                       Partnership Interest, shall be equal to the product of
                       the following: (i) the difference obtained from
                       subtracting (x) the sum of the combined Partnership
                       Interest of Crescent Equities and the General Partner as
                       calculated in Section 4.3(2) hereof, plus the aggregate
                       Non-Unitholder Partnership Interests as calculated in
                       Sections 4.2(1) and (3) hereof, from (y) one hundred
                       percent (100%), and (ii) a fraction, the numerator of
                       which is equal to the number of Partnership Units held by
                       such Limited Partner on such Contribution Date, and the
                       denominator of which is equal to the total number of
                       Partnership Units held by all Limited Partners (including
                       the Additional Limited Partner) on such Contribution
                       Date.

         The General Partner shall be authorized on behalf of each of the
Partners to amend this Agreement to reflect the admission of any Additional
Limited Partner and any reduction of the Partnership Interests of the other
Limited Partners in accordance with the provisions of this Section 4.3.

         The number of Partnership Units owned by the Limited Partners and
Assignees shall not be decreased in connection with any admission of an
Additional Limited Partner pursuant to this Section 4.3. The General Partner may
(but is not required to) grant to an Additional Limited Partner Partnership
Units, which Partnership Units shall enable the Additional Limited Partner to
participate in the Exchange Rights, upon such terms and conditions as are deemed
appropriate by the General Partner. Notwithstanding anything to the contrary
contained in this Agreement, if the value of the Partnership Units granted to an
Additional Limited Partner is determined based on the average of the "closing
price" of a REIT Share for a period of time other than the ten (10)-day period
specified in the Article I definition of "Value" (including, without limitation,
a




                                      -26-
<PAGE>   32

determination based on the "closing price" of a REIT Share for the Trading Day
immediately preceding the admission of such Additional Limited Partner), then
such other time period shall be used in calculating the "Value" of a REIT Share
for purposes of calculating the "Deemed Value of the Partnership" and the
"Deemed Partnership Interest Value" under this Section 4.3 with respect to the
admission of such Additional Limited Partner.

         Section 4.4  No Preemptive Rights

         Except as otherwise set forth in Section 4.2.A, no Person shall have
any preemptive, preferential or other similar right with respect to the making
of additional Capital Contributions or loans to the Partnership.

         Section 4.5  No Interest on Capital

         No Partner shall be entitled to interest on its Capital Contribution or
its Capital Account.

         Section 4.6  Stock Incentive Plans

               A.     Grants of REIT Shares.  If grants of REIT Shares are made
in connection with a Stock Incentive Plan,

               (1)    Crescent Equities shall, as soon as practicable after such
grant, contribute to the capital of the Partnership an amount equal to the price
(if any) paid to Crescent Equities by the party receiving the grant of REIT
Shares;

               (2)    Crescent Equities shall, as of the date on which the grant
of REIT Shares is made, be deemed to have contributed to the Partnership as
Contributed Funds pursuant to Section 4.2.A(2) hereof an amount equal to the
fair market value (computed using the "closing price" (as such term is defined
in the definition of the term "Value" in Article I hereof) as of the date on
which the grant of REIT Shares is made) of the REIT Shares delivered by Crescent
Equities to such party; and

               (3)    the General Partner's Partnership Interest shall remain
unchanged, and the Partnership Interests of Crescent Equities and the other
Limited Partners shall be adjusted as set forth in Section 4.2, based on the
amount deemed to be contributed, determined pursuant to Section 4.6.A(2);
provided that, for purposes of calculating the "Deemed Value of the Partnership"
and the "Deemed Partnership Interest Value" under Section 4.2, the "Value" of a
REIT Share shall be the "closing price" (as such term is defined in the
definition of the term "Value" in Article I hereof) of a REIT Share as of the
date on which the grant of REIT Shares is made.

         B.    Exercise of Stock Options. If stock options granted in connection
with a Stock Incentive Plan are exercised:

               (1)    Crescent Equities shall, as soon as practicable after such
exercise, contribute to the capital of the Partnership an amount equal to the
exercise price paid to Crescent Equities by the exercising party;



                                      -27-
<PAGE>   33

               (2)    Crescent Equities shall, as of the date on which the
purchase of the REIT Shares is consummated by such exercising party, be deemed
to have contributed to the Partnership as Contributed Funds pursuant to Section
4.2.A(2) hereof an amount equal to the fair market value (computed using the
"closing price" (as such term is defined in the definition of "Value" in Article
I hereof) as of the date on which such purchase of REIT Shares is consummated by
such exercising party) of the REIT Shares delivered by Crescent Equities to such
exercising party; and

               (3)    the General Partner's Partnership Interest shall remain
unchanged, and the Partnership Interests of Crescent Equities and the other
Limited Partners shall be adjusted as set forth in Section 4.2, based on the
amount deemed to be contributed, determined pursuant to Section 4.6.B(2);
provided that, for purposes of calculating the "Deemed Value of the Partnership"
and the "Deemed Partnership Interest Value" under Section 4.2, the "Value" of a
REIT Share shall be the "closing price" (as such term is defined in the
definition of the term "Value" in Article I hereof) of a REIT Share as of the
date on which the purchase of REIT Shares is consummated by the exercising
party.

         Section 4.7  Other Equity Compensation Plans

               A.     The Partnership may adopt a compensation plan for its
employees, agents or consultants pursuant to which the Partnership may grant
Limited Partnership Interests (including Partnership Units, which Partnership
Units shall enable the Limited Partner to participate in the Exchange Rights),
or options to acquire Limited Partnership Interests (including Partnership
Units, which Partnership Units shall enable the Limited Partner to participate
in the Exchange Rights), to one or more of its employees, agents or consultants
upon such terms and conditions as may be deemed necessary or appropriate by the
General Partner.

               B.     The Management Company may adopt a compensation plan for
its employees, agents or consultants pursuant to which the Management Company
may grant Limited Partnership Interests (including Partnership Units, which
Partnership Units shall enable the Limited Partner to participate in the
Exchange Rights), or options to acquire Limited Partnership Interests (including
Partnership Units, which Partnership Units shall enable the Limited Partner to
participate in the Exchange Rights), to one or more of its employees, agents or
consultants. The Partnership may sell Limited Partnership Interests (including
Partnership Units, which Partnership Units shall enable the Limited Partner to
participate in the Exchange Rights) to the Management Company for delivery to
its employees, agents or consultants. The price at which the Partnership shall
sell such Partnership Interests to the Management Company shall be the fair
market value of such Partnership Interests, as determined by the General Partner
in its reasonable discretion.

               C.     Upon any admission of an employee, agent or consultant of
the Partnership or the Management Company as an additional Limited Partner (an
"Employee Limited Partner") pursuant to Section 4.7.A or 4.7.B above, the
Partnership Interests of the other Partners shall be diluted, on a pro rata
basis, in proportion to their respective Partnership Interests, to reflect the
admission of the Employee Limited Partner. Notwithstanding the foregoing, the
Partnership Interest of the General Partner shall not be diluted upon the
admission of the Employee Limited Partner; any dilution that would otherwise
occur with respect to the Partnership Interest of the




                                      -28-
<PAGE>   34

General Partner in accordance with the terms of the preceding sentence shall be
allocated instead to Crescent Equities. The number of Partnership Units owned by
the Limited Partners and Assignees shall not be decreased in connection with any
admission of an Employee Limited Partner.

               D.     In addition to the compensation plans described in
Sections 4.6, 4.7.A and 4.7.B hereof, the General Partner, in its sole and
absolute discretion and without the approval of the Limited Partners, may
propose and adopt on behalf of the Partnership employee benefit plans or other
incentive compensation plans (including, without limitation, plans granting REIT
Shares or options to purchase REIT Shares, plans granting Partnership Interests
(including Partnership Units) or options to purchase Partnership Interests
(including Partnership Units), "phantom" equity plans or other plans in which
compensation is tied to revenue or income amounts, or based on increases in the
market value of equity ownership interests) for the benefit of employees, agents
or consultants of any member of the Crescent Group, the Partnership, the
Management Company, the Subsidiary Development Corporation(s) or any Affiliate
of the foregoing in respect of services performed, directly or indirectly, for
the benefit of the Crescent Group, the Partnership, the Management Company or
the Subsidiary Development Corporation(s).

                                 DISTRIBUTIONS

         Section 5.1  Initial Partnership Distributions

         Upon execution of the First Amended and Restated Agreement, the
Partnership made (i) a distribution of one million five hundred thousand dollars
($1,500,000) to RainAm Investors, and (ii) a distribution in an amount equal to
the Amstar Required Cash Payment to Amstar. In addition, the Partnership
returned to the General Partner, CRE Limited Partner, Inc. and Gerald W. Haddock
the initial capital contributions of one dollar ($1), seventy-four dollars ($74)
and twenty-five dollars ($25), respectively, previously made by such Persons to
the Partnership.

         Section 5.2  Requirement and Characterization of Distributions

         The General Partner shall cause the Partnership to distribute quarterly
all, or such portion deemed appropriate by the General Partner, of Available
Cash generated by the Partnership during such quarter to the Partners who are
Partners on the Partnership Record Date with respect to such quarter in
accordance with their respective Partnership Interests on such Partnership
Record Date. The General Partner shall take such reasonable efforts, as
determined by it in its sole and absolute discretion and consistent with the
qualification of Crescent Equities as a REIT, to distribute Available Cash to
the Limited Partners so as to preclude any such distribution or portion thereof
from being treated as part of a sale of property to the Partnership by a Limited
Partner under Section 707 of the Code or the Regulations thereunder; provided
that the General Partner and the Partnership shall not have any liability to a
Limited Partner under any circumstances as a result of any distribution to a
Limited Partner being so treated. Notwithstanding the foregoing, the General
Partner shall use its best efforts to cause the Partnership to distribute
sufficient amounts to enable Crescent Equities to pay shareholder dividends that
will (i) allow Crescent Equities to



                                      -29-
<PAGE>   35

achieve and maintain qualification as a REIT, and (ii) avoid the imposition of
any additional taxes under Section 857 or Section 4981 of the Code.

         Section 5.3  Amounts Withheld

         All amounts withheld pursuant to the Code or any provisions of any
state or local tax law and Section 10.5 hereof with respect to any allocation,
payment or distribution to a Partner shall be treated as amounts distributed to
such Partner pursuant to Section 5.2 for all purposes under this Agreement.

         Section 5.4  Distributions In Kind

         Pursuant to Section 17-605 of the Act, the General Partner has the
authority to make in-kind distributions of assets to the Partners. Any such
distributions in kind shall be distributed among the Partners in the same manner
as set forth in Section 5.2 with respect to Available Cash (provided that
distributions in kind made after commencement of the liquidation of the
Partnership shall be distributed to the Partners in accordance with Section
13.2). The General Partner shall determine the fair market value of any assets
distributed in kind using such reasonable method of valuation as it may adopt.

         Section 5.5  Distributions Upon Liquidation

         Proceeds from a Terminating Capital Transaction and any other cash
received or reductions in reserves made after commencement of the liquidation of
the Partnership shall be distributed to the Partners in accordance with Section
13.2.

                                   ARTICLE VI
                                   ALLOCATIONS

         Section 6.1  Allocations For Capital Account Purposes

         For purposes of maintaining the Capital Accounts and in determining the
rights of the Partners among themselves, the Partnership's items of income,
gain, loss and deduction (computed in accordance with Exhibit B hereof) shall be
allocated among the Partners in each taxable year (or portion thereof) as
provided herein below.

               A.     Net Income. After giving effect to the special allocations
set forth in Section 1 of Exhibit C, Net Income shall be allocated (i) first, to
the General Partner to the extent that Net Losses previously allocated to the
General Partner pursuant to the last sentence of Section 6.1.B exceed Net Income
previously allocated to the General Partner pursuant to this clause (i) of
Section 6.1.A, and (ii) thereafter, Net Income shall be allocated to the
Partners in accordance with their respective Partnership Interests.

               B.     Net Losses. After giving effect to the special allocations
set forth in Section 1 of Exhibit C, Net Losses shall be allocated to the
Partners in accordance with their



                                      -30-
<PAGE>   36

respective Partnership Interests, provided that Net Losses shall not be
allocated to any Limited Partner pursuant to this Section 6.1.B to the extent
that such allocation would cause such Limited Partner to have an Adjusted
Capital Account Deficit at the end of such taxable year (or increase any
existing Adjusted Capital Account Deficit). All Net Losses in excess of the
limitations set forth in this Section 6.1.B shall be allocated to the General
Partner.

               C.     Allocations to Reflect Issuance of New Interests. In the
event that the Partnership issues New Interests to Crescent Equities pursuant to
Section 8.7.C, the General Partner shall make such revisions to Sections 6.1.A
and B above as it determines are necessary to reflect the issuance of such New
Interests.

         Section 6.2  Allocation of Nonrecourse Debt

         For purposes of Regulations Section 1.752-3(a), the Partners agree that
Nonrecourse Liabilities of the Partnership in excess of the sum of (i) the
amount of Partnership Minimum Gain and (ii) the total amount of Nonrecourse
Built-in Gain shall be allocated among the Partners in accordance with their
respective Partnership Interests.

                                  ARTICLE VII
                      MANAGEMENT AND OPERATIONS OF BUSINESS

         Section 7.1  Management

               A.     Except as otherwise expressly provided in this Agreement,
all management powers over the business and affairs of the Partnership are
exclusively vested in the General Partner, and no Limited Partner shall have any
right to participate in or exercise control or management power over the
business and affairs of the Partnership. The General Partner may not be removed
by the Limited Partners with or without cause. In addition to the powers now or
hereafter granted a general partner of a limited partnership under applicable
law or which are granted to the General Partner under any other provision of
this Agreement, the General Partner, subject to Section 7.3 hereof, shall have
full power and authority to do all things and perform all acts specified in this
Agreement or otherwise deemed necessary or desirable by it to conduct the
business of the Partnership, to exercise all Partnership powers set forth in
Section 3.2 hereof and to effectuate the Partnership purposes set forth in
Section 3.1 hereof (to the extent consistent with allowing Crescent Equities at
all times to qualify as a REIT, unless Crescent Equities voluntarily terminates
its REIT status pursuant to the Declaration of Trust), including, without
limitation, to:

               (1)     acquire interests in real or personal property of any
                       kind and type, and any and all kinds of interests
                       therein, and determine the manner in which title thereto
                       is to be held; manage, insure against loss, protect and
                       subdivide any such property; improve, develop or
                       redevelop any such property; dedicate for public use,
                       vacate any such property subdivisions or parts thereof,
                       or resubdivide such property or any part thereof; lease,
                       renew or extend leases, amend, change or modify the terms
                       and provisions of leases, and grant options to lease and
                       options to renew leases and options to purchase;

                       partition, sell or otherwise dispose of all or any
                       portion of such property; exchange all or any portion of

                       insure any Person having an interest in or responsibility
                       for the care, management or repair of such property;
                       direct the trustee of any land trust to mortgage, lease,
                       convey or contract to convey the real estate held in such
                       land trust or to execute and deliver deeds, mortgages,
                       notes, and any and all documents pertaining to the
                       property subject to such land trust or in any matter
                       regarding such trust; and execute assignments of all or
                       any part of the beneficial interest in such land trust;

                       management of the Partnership business, including, but
                       not limited to, employees, including employees having
                       such titles as the General Partner may from time to time
                       specify, such as "chairman of the board," "chief
                       executive officer," chief operating officer,"

                       the Partnership to make distributions in such amounts as

                       Equities elects to qualify as a REIT) to avoid the

                       the conservation of the Partnership's assets or for any

                       defend, answer or oppose, contest and abandon all legal

                       arbitration any accounts, debts, claims, disputes and
                       matters which may arise between the Partnership and any
                       other Person and grant an extension of time for the
                       payment or satisfaction thereof on any terms, with or
                       without security; and indemnify any Indemnitees against
                       liabilities and contingencies in accordance with the

                       into by the Partnership from time to time in accordance
                       with the provisions of this Agreement, including periodic
                       reports as required to lenders; and use all due diligence

                       ventures, real estate investment trusts, or other
                       entities upon such terms and conditions as General
                       Partner deems appropriate;

               (10)    invest assets of the Partnership on a temporary basis in
                       commercial paper, government securities, checking or
                       savings accounts, money market funds, or any other highly

                       Partner; make loans, including participating or
                       convertible loans, to other Persons (including, without
                       limitation, the Subsidiary Development Corporation(s) and
                       the Management Company) upon such terms and conditions,
                       and for such security, as deemed appropriate by the
                       General Partner; repay obligations of any Person in which
                       the Partnership has an equity investment (including,
                       without limitation, the Subsidiary Development
                       Corporation(s) and the Management Company); and purchase
                       existing debt obligations held by other Persons,
                       including participating or convertible debt obligations,
                       upon such terms and conditions, and for such security, as
                       deemed appropriate by the General Partner;

               (11)    negotiate, execute and perform any contracts, conveyance
                       or other instruments that the General Partner considers
                       useful or necessary to the conduct of the Partnership's
                       operations or the implementation of the General Partner's
                       powers under this Agreement;

               (12)    distribute Partnership cash or other assets in accordance
                       with this Agreement;

               (13)    maintain the Partnership's books and records;

               (14)    prepare and deliver all financial, regulatory, tax and
                       other filings or reports to governmental or other
                       agencies having jurisdiction over the Partnership; and

               (15)    take any action in connection with the Partnership's
                       direct or indirect investment in any other Person.

               B.     Each of the Limited Partners agrees that the General
Partner is authorized to execute, deliver and perform the above-mentioned
agreements and transactions on behalf of the Partnership without any further
act, approval or vote of the Partners, notwithstanding any other provisions of
this Agreement (except as provided in Section 7.3), the Act or any applicable
law, rule or regulation. The execution, delivery or performance by the General
Partner or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that
the General Partner may owe the Partnership or the Limited Partners or any other
Persons under this Agreement or of any duty stated or implied by law or equity.



                                      -34-

               C.     At all times from and after the date hereof, the General
Partner may cause the Partnership to obtain and maintain (i) casualty, liability
and other insurance on the properties of the Partnership and (ii) liability
insurance for the Indemnitees hereunder.

               D.     At all times from and after the date hereof, the General
Partner may cause the Partnership to establish and maintain working capital
reserves in such amounts as the General Partner, in its sole and absolute
discretion, deems appropriate and reasonable from time to time.

               E.     In exercising its authority under this Agreement, the
General Partner may, but shall be under no obligation to, take into account the
tax consequences to any Partner of any action taken by it. The General Partner
and the Partnership shall not have liability to a Limited Partner under any
circumstances as a result of an income tax liability incurred by such Limited
Partner as a result of an action (or inaction) by the General Partner pursuant
to its authority under this Agreement.

         Section 7.2  Certificate of Limited Partnership

         To the extent that such action is determined by the General Partner to
be necessary or appropriate, the General Partner shall file amendments to and
restatements of the Certificate and do all things necessary or appropriate to
maintain the Partnership as a limited partnership (or a partnership in which the
limited partners have limited liability) under the laws of the State of Delaware
and each other jurisdiction in which the Partnership may elect to do business or
own property. Subject to the terms of Section 8.5.A(3) hereof, the General
Partner shall not be required, before or after filing, to deliver or mail a copy
of the Certificate or any amendment thereto to any Limited Partner. The General
Partner shall use all reasonable efforts to cause to be filed such other
certificates or documents as may be reasonable and necessary or appropriate for
the continuation, qualification and operation of a limited partnership (or a
partnership in which the limited partners have limited liability) in the State
of Delaware and any other jurisdiction in which the Partnership may elect to do
business or own property.

         Section 7.3  Restrictions on General Partner's Authority

         The General Partner shall not have the authority to:

               A.     take any action in contravention of this Agreement or
which would make it impossible to carry on the ordinary business of the
Partnership;

               B.     possess Partnership property, or assign any rights in
specific Partnership property, for other than a Partnership purpose;

               C.     do any act in contravention of applicable law; or

               D.     perform any act that would subject a Limited Partner to
liability as a general partner in any jurisdiction or any other liability except
as provided herein or under the Act.

         Section 7.4  Reimbursement of the Crescent Group

               A.     Except as provided in this Section 7.4 and elsewhere in
this Agreement (including the provisions of Articles 5 and 6 regarding
distributions, payments, and allocations to which it may be entitled), the
General Partner shall not be compensated for its services as general partner of
the Partnership.

               B.     The Crescent Group shall be reimbursed on a monthly basis,
or such other basis as the General Partner may determine in its sole and
absolute discretion, for all expenses the Crescent Group incurs relating to the
ownership and operation of, or for the benefit of, the Partnership, provided
that the amount of any such reimbursement shall be reduced by any interest paid
to the Crescent Group with respect to bank accounts or other instruments held by
it as permitted in Section 7.5. The Limited Partners acknowledge that the
Crescent Group's sole business is the ownership of interests in and operation of
the Partnership, and that all of the Crescent Group's operating expenses
(including, without limitation, costs and expenses relating to the formation and
continuity of existence of the Crescent Group, costs and expenses associated
with compliance with the periodic reporting requirements and all other rules and
regulations of the SEC or any other federal, state or local regulatory body,
salaries payable to officers and employees of the Crescent Group, fees and
expenses payable to directors of the Crescent Group, and all other operating or
administrative costs of the Crescent Group) are incurred for the benefit of the
Partnership and shall be reimbursed by the Partnership. Such reimbursements
shall be in addition to any reimbursement to the Crescent Group as a result of
indemnification pursuant to Section 7.7 hereof. If and to the extent any
reimbursements to the Crescent Group are determined for federal income tax
purposes not to constitute payment of expenses of the Partnership, the amounts
so determined shall constitute guaranteed payments within the meaning of Section
707(c) of the Code, shall be treated consistently therewith by the Partnership
and all Partners, and shall not be treated as distributions for purposes of
computing the Partners' Capital Accounts.

         Section 7.5  Outside Activities of the Crescent Group

         The Crescent Group shall not directly or indirectly enter into or
conduct any business, other than in connection with the ownership, acquisition
and disposition of Partnership Interests and the management of the business of
the Partnership, and such activities as are incidental thereto. The Crescent
Group shall not own any assets other than Partnership Interests in the
Partnership, and such bank accounts or similar instruments as it deems necessary
to carry out its responsibilities contemplated under this Agreement and the
Declaration of Trust. The Crescent Group shall not borrow funds for the purpose
of making distributions to the shareholders of any member of the Crescent Group
unless such borrowing is effectuated through the Partnership. Notwithstanding
anything to the contrary contained above in this Section 7.5, Crescent Equities
may form additional direct or indirect wholly owned subsidiary entities to serve
as general partners of partnerships or managing members of limited liability
companies in which the Partnership also owns a direct or indirect ownership
interest, provided that (i) the General Partner determines that the formation of
the subsidiary entities is necessary or appropriate to further the business
objectives of the Partnership and (ii) the subsidiary entities (a) make capital
contributions in exchange for their ownership interests in the partnerships and
limited liability companies on a pro





                                      -36-
<PAGE>   42

rata basis with the Partnership and (b) do not own more than one percent (1%) of
the total ownership interests in any such partnership or limited liability
company.

         Section 7.6  Contracts with Affiliates

               A.     The Partnership may contribute assets and loan funds to
joint ventures, other partnerships, corporations or other business entities in
which it is or thereby becomes a participant upon such terms and subject to such
conditions consistent with this Agreement and applicable law as the General
Partner, in its sole and absolute discretion, deems advisable. The foregoing
authority shall not create any right or benefit in favor of any such other
business entities.

               B.     Except as expressly permitted by this Agreement, no
Partner or Affiliate of a Partner shall sell, transfer or convey any property
to, purchase any property from, lend or borrow funds, provide services to, or
enter into any other transaction with the Partnership, directly or indirectly,
except pursuant to transactions that are on terms that are fair and reasonable
and no less favorable to the Partnership than could be obtained from an
unaffiliated third party.

               C.     The General Partner is expressly authorized to enter into,
in the name and on behalf of the Partnership, noncompetition agreements and
other conflict avoidance agreements for its benefit with various Affiliates of
the Partnership and its Partners, on such terms as the General Partner, in its
sole and absolute discretion, believes are advisable.

         Section 7.7  Indemnification

               A.     The Partnership shall indemnify each Indemnitee from and
against any and all losses, claims, damages, liabilities, joint or several,
expenses (including, without limitation, attorneys' fees and other legal fees
and expenses), judgments, fines, settlements, and other amounts arising from any
and all claims, demands, actions, suits or proceedings, civil, criminal,
administrative or investigative, that relate to the operations of the
Partnership as set forth in this Agreement in which such Indemnitee may be
involved, or is threatened to be involved, as a party or otherwise, unless it is
established that: (i) the act or omission of the Indemnitee was material to the
matter giving rise to the proceedings and either was committed in bad faith or
was the result of active and deliberate dishonesty; (ii) the Indemnitee actually
received an improper personal benefit in money, property or services; or (iii)
in the case of any criminal proceeding, the Indemnitee had reasonable cause to
believe that the act or omission was unlawful. Without limitation, the foregoing
indemnity shall extend to any liability of any Indemnitee, pursuant to a loan
guaranty or otherwise, for any indebtedness of the Partnership or any subsidiary
entity (including, without limitation, any indebtedness which the Partnership or
any subsidiary entity has assumed or taken subject to), and the General Partner
is hereby authorized and empowered, on behalf of the Partnership, to enter into
one or more indemnity agreements consistent with the provisions of this Section
7.7 in favor of any Indemnitee having or potentially having liability for any
such indebtedness. The termination of any proceeding by judgment, order or
settlement does not create a presumption that the Indemnitee did not meet the
requisite standard of conduct set forth in this Section 7.7.A. The termination
of any proceeding by conviction of an Indemnitee or upon a plea




                                      -37-
<PAGE>   43
of nolo contendre or its equivalent by an Indemnitee, or an entry of an order of
probation against an Indemnitee prior to judgment, creates a rebuttable
presumption that such Indemnitee acted in a manner contrary to that specified in
this Section 7.7.A with respect to the subject matter of such proceeding.

               B.     The right to indemnification conferred in this Section 7.7
shall be a contract right and shall include the right of each Indemnitee to be
paid by the Partnership the expenses incurred in defending any such proceeding
in advance of its final disposition; provided, however, that the payment of such
expenses in advance of the final disposition of a proceeding shall be made only
upon delivery to the Partnership of (i) a written affirmation of the Indemnitee
of his or her good faith belief that the standard of conduct necessary for
indemnification by the Partnership pursuant to this Section 7.7 has been met,
and (ii) a written undertaking by or on behalf of the Indemnitee to repay all
amounts so advanced if it shall ultimately be determined that the standard of
conduct has not been met.

               C.     The indemnification provided pursuant to this Section 7.7
shall continue as to a Person who has ceased to have the status of an Indemnitee
pursuant to clause (i) of the definition of "Indemnitee" set forth in Article I
hereof and shall inure to the benefit of the heirs, successors, assigns,
executors and administrators of any such Person, or to a Person whose status as
an Indemnitee was originally established pursuant to clause (ii) of such
definition and was later terminated for any reason other than the affirmative
decision of the General Partner to terminate such status; provided, however,
that except as provided in Section 7.7.D with respect to proceedings seeking to
enforce rights to indemnification, the Partnership shall indemnify any such
Person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such Person only if such proceeding (or part thereof) was
authorized by the General Partner.

               D.     If a claim under Sections 7.7.A, 7.7.B or 7.7.C is not
paid in full by the Partnership within thirty (30) calendar days after a written
claim has been received by the Partnership, the Indemnitee making such claim may
at any time thereafter (but prior to payment of the claim) bring suit against
the Partnership to recover the unpaid amount of the claim and, if successful, in
whole or in part, such Indemnitee shall be entitled to be paid also the expense
of prosecuting such claim. It shall be a defense to any such action (other than
an action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its final disposition where the required undertaking,
if any, has been tendered to the Partnership) that the Indemnitee has not met
the standards of conduct set forth above which make it permissible for the
Partnership to indemnify the Indemnitee for the amount claimed, but the burden
of proving such defense shall be on the Partnership. Neither the failure of the
Partnership to have made a determination prior to the commencement of such
action that indemnification of the Indemnitee is proper in the circumstances
because he or she has met the applicable standard of conduct set forth herein
nor an actual determination by the Partnership that the Indemnitee has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that the Indemnitee has not met the applicable standard of
conduct.

               E.     Following any "change in control" of Crescent Equities of
the type required to be reported under Item 1 of Form 8-K promulgated under the
Exchange Act, any




                                      -38-
<PAGE>   44

determination as to entitlement to indemnification shall be made by independent
legal counsel selected by the Indemnitee, which such independent legal counsel
shall be retained by the General Partner on behalf of the Partnership and at the
expense of the Partnership.

               F.     The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this Section 7.7 shall not be exclusive of any other right which any person
may have or hereafter acquire under any statute or agreement, or pursuant to any
vote of the Partners, or otherwise.

               G.     The Partnership may purchase and maintain insurance, at
its expense, on its own behalf and on behalf of any Indemnitee and of such other
Persons as the General Partner shall determine, against any liability (including
expenses) that may be asserted against and incurred by such Person in connection
with the Partnership's activities pursuant to this Agreement, whether or not the
Partnership would have the power to indemnify such Person against such liability
under the terms of this Agreement. In addition, the Partnership may, together
with Crescent Equities, enter into indemnification agreements with one or more
of the Indemnitees pursuant to which the Partnership and Crescent Equities shall
jointly and severally agree to indemnify such Indemnitee(s) to the fullest
extent permitted by law, and advance to such Indemnitee(s) all related expenses,
subject to reimbursement if it is subsequently determined that indemnification
is not permitted.

               H.     Any indemnification pursuant to this Section 7.7 shall be
made only out of assets of the Partnership, and neither the General Partner nor
any Limited Partner shall have any obligation to contribute to the capital of
the Partnership or otherwise provide funds to enable the Partnership to fund its
obligations under this Section 7.7.

               I.     No Limited Partner shall be liable for the obligations of
the Partnership by reason of the indemnification provisions set forth in this
Agreement.

               J.     An Indemnitee shall not be denied indemnification in whole
or in part pursuant to this Section 7.7 because such Indemnitee has an interest
in the transaction to which the indemnification relates if the transaction
otherwise was permitted by the terms of this Agreement.

               K.     The provisions of this Section 7.7 are for the benefit of
the Indemnitees, their heirs, successors, assigns, executors and administrators,
and shall not be deemed to create any rights for the benefit of any other
Person. Any amendment, modification or repeal of this Section 7.7 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the Partnership's liability to any Indemnitee under this Section
7.7 as in effect immediately prior to such amendment, modification or repeal
with respect to claims arising from or relating to matters occurring, in whole
or in part, prior to such amendment, modification or repeal, regardless of when
such claims may arise or be asserted.

         Section 7.8  Liability of the General Partner

               A.     Notwithstanding anything to the contrary set forth in this
Agreement, the General Partner shall not be liable for monetary damages to the
Partnership or any Partners for




                                      -39-
<PAGE>   45

losses sustained or liabilities incurred as a result of errors in judgment or of
any act or omission if the General Partner acted in good faith.

               B.     The Limited Partners expressly acknowledge that the
General Partner is acting on behalf of the Partnership and the shareholders of
Crescent Equities collectively, that the General Partner is under no obligation
to consider the separate interests of the Limited Partners (including, without
limitation, the tax consequences to Limited Partners) in deciding whether to
cause the Partnership to take (or decline to take) any actions, and that the
General Partner shall not be liable to the Partnership or to any Partner for
monetary damages for losses sustained, liabilities incurred, or benefits not
derived by Limited Partners in connection with such decisions, provided that the
General Partner has acted in good faith.

               C.     Subject to its obligations and duties as General Partner
set forth in Section 7.1.A hereof, the General Partner may exercise any of the
powers granted to it by this Agreement and perform any of the duties imposed
upon it hereunder either directly or by or through its agents. The General
Partner shall not be responsible for any misconduct or negligence on the part of
any such agent appointed by it in good faith.

               D.     Any amendment, modification or repeal of this Section 7.8
or any provision hereof shall be prospective only and shall not in any way
affect the limitations on the General Partner's liability to the Partnership and
the Limited Partners under this Section 7.8 as in effect immediately prior to
such amendment, modification or repeal with respect to claims arising from or
relating to matters occurring, in whole or in part, prior to such amendment,
modification or repeal, regardless of when such claims may arise or be asserted.

         Section 7.9  Other Matters Concerning the General Partner

               A.     The General Partner may rely, and shall be protected in
acting or refraining from acting, upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, debenture,
or other paper or document believed by it to be genuine and to have been signed
or presented by the proper party or parties.

               B.     The General Partner may consult with legal counsel,
accountants, appraisers, management consultants, investment bankers and other
consultants and advisers selected by it, and any act taken or omitted to be
taken in reliance upon the opinion of such Persons as to matters which such
General Partner reasonably believes to be within such Person's professional or
expert competence shall be conclusively presumed to have been done or omitted in
good faith.

               C.     The General Partner shall have the right, in respect of
any of its powers or obligations hereunder, to act through any of its duly
authorized officers and a duly appointed attorney or attorneys-in-fact. Each
such attorney shall, to the extent provided by the General Partner in the power
of attorney, have full power and authority to do and perform all and every act
and duty which is permitted or required to be done by the General Partner
hereunder.

               D.     Notwithstanding any other provision of this Agreement or
the Act, any action of the General Partner on behalf of the Partnership or any
decision of the General Partner to refrain from acting on behalf of the
Partnership, undertaken in the good faith belief that such action or omission is
necessary or advisable in order (i) to protect the ability of Crescent Equities
to achieve or maintain qualification as a REIT or (ii) to avoid the incurring by
Crescent Equities of any taxes under Section 857 or Section 4981 of the Code, is
expressly authorized under this Agreement and is deemed approved by all of the
Limited Partners, to the extent such approval may be necessary.

         Section 7.10  Title to Partnership Assets

         Title to Partnership assets, whether real, personal or mixed and
whether tangible or intangible, shall be deemed to be owned by the Partnership
as an entity, and no Partner, individually or collectively, shall have any
ownership interest in such Partnership assets or any portion thereof. Title to
any or all of the Partnership assets may be held in the name of the Partnership,
the General Partner or one or more nominees, as the General Partner may
determine, including Affiliates of the General Partner. The General Partner
hereby declares and warrants that any Partnership assets for which legal title
is held in the name of the General Partner or any nominee or Affiliate of the
General Partner shall be held by the General Partner for use and benefit of the
Partnership in accordance with the provisions of this Agreement; provided,
however, that the General Partner shall use its best efforts to cause beneficial
and record title to such assets to be vested in the Partnership as soon as
reasonably practicable. All Partnership assets shall be recorded as the property
of the Partnership in its books and records, irrespective of the name in which
legal title to such Partnership assets is held.

         Section 7.11  Reliance by Third Parties

         Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority to encumber, sell or otherwise use in any
manner any and all assets of the Partnership and to enter into any contracts on
behalf of the Partnership, and such Person shall be entitled to deal with the
General Partner as if it were the Partnership's sole party in interest, both
legally and beneficially. Each Limited Partner hereby waives any and all
defenses or other remedies which may be available against such Person to
contest, negate or disaffirm any action of the General Partner in connection
with any such dealing. In no event shall any Person dealing with the General
Partner or its representatives be obligated to ascertain that the terms of this
Agreement have been complied with or to inquire into the necessity or expedience
of any act or action of the General Partner or its representatives. Each and
every certificate, document or other instrument executed on behalf of the
Partnership by the General Partner or its representatives shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and delivery of such certificate, document
or instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership, and
(iii) such certificate, document or instrument was duly executed and delivered
in accordance with the terms and provisions of this Agreement and is binding
upon the Partnership.

         Section 7.12  Limited Partner Representatives

         Any Limited Partner may (but shall not be required to) appoint a
representative (the "Representative") who shall have full power and authority to
exercise all rights, including consent rights, of such Limited Partner under
this Agreement. Any such appointment shall be made in a writing delivered by the
Limited Partner to the General Partner. The same Person may serve as
Representative for more than one Limited Partner. Any action taken by a
Representative on behalf of a Limited Partner shall be fully binding on such
Limited Partner. The General Partner shall be entitled to rely on the actions
taken by a Representative without further evidence of its authority or further
action by the Limited Partner who appointed such Representative. Any appointment
of a Representative shall remain effective until rescinded in a writing
delivered by the Limited Partner to the General Partner. A Limited Partner may
revoke its designation of a Representative, or replace a designated
Representative with a different Representative, at any time by delivering
written notice of such action to the General Partner.

                                  ARTICLE VIII
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

         No Limited Partner (other than any officer, director, employee,

their Affiliates, in his, her or its capacity as such) shall take part in the
operation, management or control (within the meaning of the Act) of the
Partnership's business, transact any business in the Partnership's name or have
the power to sign documents for or otherwise bind the Partnership. The
transaction of any such business by the General Partner, any of its Affiliates
or any officer, director, employee, partner, agent or trustee of the General
Partner, the Partnership or any of their Affiliates, in their capacity as such,
shall not affect, impair or eliminate the limitations on the liability of the
Limited Partners under this Agreement.

         Section 8.3  Outside Activities of Limited Partners

         Subject to Section 7.5 hereof, and subject to any agreements entered
into pursuant to Section 7.6.C hereof and any other agreements entered into by a

any officer, director, employee, agent, trustee, Affiliate or shareholder of any
Limited Partner shall be entitled to and may have business interests and engage
in business activities in addition to those relating to the Partnership,
including business interests and activities in direct competition with the
Partnership. Neither the Partnership nor any Partners shall have any rights by
virtue of this Agreement in any business ventures of any Limited Partner. None
of the Limited Partners nor any other Person shall have the rights by virtue of
this




                                      -42-
<PAGE>   48

Agreement or the partnership relationship established hereby in any business
ventures of any other Person, other than the Crescent Group, and such Person
shall have no obligation pursuant to this Agreement to offer any interest in any
such business ventures to the Partnership, any Limited Partner or any such other
Person, even if such opportunity is of a character which, if presented to the
Partnership, any Limited Partner or such other Person, could be taken by such
Person.

         Section 8.4  Return of Capital

         Except pursuant to the Exchange Rights set forth in Section 8.6, no
Limited Partner shall be entitled to the withdrawal or return of his Capital
Contribution, except to the extent of distributions made pursuant to this
Agreement or upon termination of the Partnership as provided herein. No Limited
Partner shall have priority over any other Limited Partner either as to the
return of Capital Contributions or, except to the extent provided by Exhibit C
hereof or as permitted by Section 8.7.C, or otherwise expressly provided in this
Agreement, as to profits, losses or distributions.

         Section 8.5  Rights of Limited Partners Relating to the Partnership

               A.     In addition to other rights provided by this Agreement or
by the Act, and except as limited by Section 8.5.C hereof, each Limited Partner
shall have the right, for a purpose reasonably related to such Limited Partner's
interest as a limited partner in the Partnership, upon written demand with a
statement of the purpose of such demand and at such Limited Partner's own
expense:

               (1)    to obtain a copy of the Partnership's federal, state and
                      local income tax returns for each fiscal year;

               (2)    to obtain a current list of the name and last known
                      business, residence or mailing address of each Partner;
                      provided, however, that the General Partner may require,
                      as a condition of providing such list to the Limited
                      Partner, that the Limited Partner confirm in writing to
                      the General Partner that the names of the Partners and
                      other information provided by the list will be held in
                      strictest confidence and no distribution of the list will
                      be made;

               (3)    to obtain a copy of this Agreement and the Certificate,
                      and all amendments to the Agreement and the Certificate,
                      together with executed copies of all powers of attorney
                      pursuant to which this Agreement, the Certificate and all
                      amendments to the Agreement and the Certificate have been
                      executed; and

               (4)    to obtain true and full information regarding the amount
                      of cash and a description and statement of any other
                      property or services contributed by each Partner and which
                      each Partner has agreed to contribute in the future, and
                      the date on which each became a Partner.

<PAGE>   49

               B.     The Partnership shall notify each Limited Partner in
writing of any change made to the Exchange Factor. Such written notification
shall be included with the quarterly financial statements that are sent to each
Limited Partner pursuant to Section 9.3 hereof.

               C.     Notwithstanding any other provision of this Section 8.5,
the General Partner may keep confidential from the Limited Partners, for such
period of time as the General Partner determines in its sole and absolute
discretion to be reasonable, any information that (i) the General Partner
believes to be in the nature of trade secrets or other information the
disclosure of which the General Partner in good faith believes is not in the
best interests of the Partnership, or (ii) the Partnership is required by law or
by agreements with unaffiliated third parties to keep confidential.

         Section 8.6  Exchange Rights

               A.     Subject to the limitations set forth herein, in Section
8.6.B below and in Exhibit A, each Limited Partner or Assignee owning
Partnership Units shall have the right (the "Exchange Right") to require
Crescent Equities to exchange on any Specified Exchange Date all or any portion
of the Partnership Units owned by such Limited Partner or Assignee (an
"Exchanging Person") for consideration consisting of (i) an amount of cash equal
to the Cash Amount, (ii) a number of REIT Shares equal to the REIT Shares
Amount, or (iii) any combination of (i) or (ii) above, with the decision as to
the type of consideration to be given to the Exchanging Person to be made by
Crescent Equities, in its sole and absolute discretion. The Exchange Right shall
be exercised pursuant to a Notice of Exchange delivered to Crescent Equities by
the Exchanging Person, accompanied by any certificate or certificates evidencing
the Partnership Units to be exchanged. If Crescent Equities elects to pay all or
any portion of the consideration to an Exchanging Person in cash, the Crescent
Group agrees to use its best efforts to raise any required funds as quickly as
possible after receipt of the Notice of Exchange.

               B.     Notwithstanding anything to the contrary contained in
Section 8.6.A above, to the extent that the delivery of REIT Shares to an
Exchanging Person pursuant to Section 8.6.A above would cause the Exchanging
Person to violate the applicable "Ownership Limit" or the "Existing Holder
Limit" set forth in the Declaration of Trust, Crescent Equities may not deliver
REIT Shares to such Exchanging Person but may, in its sole and absolute
discretion, elect to either (1) pay the consideration to the Exchanging Person
in the form of the Cash Amount, or (2) refuse, in whole or in part, to accept
the Notice of Exchange.

         Section 8.7  Covenants Relating to the Exchange Rights

               A.     Crescent Equities shall at all times reserve for issuance
such number of REIT Shares as may be necessary to enable it to issue such REIT
Shares in full satisfaction of the Exchange Rights with respect to all
Partnership Units which are from time to time outstanding.

               B.     As long as Crescent Equities shall be obligated to file
periodic reports under the Exchange Act, Crescent Equities shall use its best
efforts to file such reports in such manner as shall enable any recipient of
REIT Shares issued pursuant to Section 8.6 in reliance upon an




                                      -44-
<PAGE>   50

exemption from registration under the Securities Act to continue to be eligible
to utilize Rule 144 promulgated by the SEC pursuant to the Securities Act, or
any successor rule or regulation or statute thereunder, for the resale thereof.

               C.     Crescent Equities shall not issue any additional REIT
Shares (other than REIT Shares contemplated by Sections 4.2 and 8.6 and REIT
Shares issued pursuant to a Stock Incentive Plan) other than on a pro rata basis
to all holders of REIT Shares. Crescent Equities shall not issue any preferred
stock or rights, options, warrants or convertible or exchangeable securities
containing the right to subscribe for or purchase REIT Shares ("New Securities")
other than to all holders of REIT Shares unless (i) the General Partner shall
cause the Partnership to issue to Crescent Equities preferred equity ownership
interests or rights, options, warrants or convertible or exchangeable securities
of the Partnership ("New Interests") having designations, preferences and other
rights, all such that the economic interests are substantially similar to those
of the New Securities, and (ii) Crescent Equities contributes the proceeds from
the issuance of such New Securities and from the exercise of rights contained in
such New Securities to the Partnership. The Partners hereby acknowledge and
agree that the proceeds received by Crescent Equities in exchange for the
issuance of New Securities may be cash or real property or an interest therein.
If any New Securities are subsequently converted or exchanged for REIT Shares,
(i) Crescent Equities shall, as of the date on which the conversion or exchange
is consummated, be deemed to have contributed to the Partnership as Contributed
Funds pursuant to Section 4.2.A(2) hereof an amount equal to the Value (computed
as of the Business Day immediately preceding the date on which such conversion
or exchange of the New Securities is consummated) of the REIT Shares delivered
by Crescent Equities to such holder of New Securities, and (ii) the Partnership
Interests of Crescent Equities and the other Limited Partners shall be adjusted
as set forth in Section 4.2. The number of Partnership Units held by the Limited
Partners shall not be decreased in connection with the issuance of any New
Securities or in connection with any subsequent conversion or exchange of any
New Securities for REIT Shares.

               D.     Each Limited Partner and Assignee covenants and agrees
that all Partnership Units delivered for exchange pursuant to Section 8.6 hereof
shall be delivered to Crescent Equities free and clear of all Liens and,
notwithstanding anything herein contained to the contrary, Crescent Equities
shall be under no obligation to acquire Partnership Units which are or may be
subject to any Liens. Each Limited Partner and Assignee further agrees that, in
the event any state or local property transfer tax is payable as a result of the
transfer of its Partnership Units to Crescent Equities, such Limited Partner or
Assignee shall assume and pay such transfer tax.

               E.     In the event Crescent Equities purchases REIT Shares, then
the General Partner shall cause the Partnership to purchase from Crescent
Equities a portion of its Partnership Interest on the same terms that Crescent
Equities purchased such REIT Shares.

         Section 8.8  Other Matters Relating to the Exchange Rights

               A.     Any Partnership Units transferred to Crescent Equities in
connection with the exercise of the Exchange Rights shall be canceled.




                                      -45-
<PAGE>   51

               B.     Upon any transfer of Partnership Units by an Exchanging
Person to Crescent Equities pursuant to Section 8.6 above, the Partnership
Interest of such Limited Partner or Assignee shall be decreased (and the
Partnership Interest of Crescent Equities shall be correspondingly increased) as
provided in this Section 8.8.B. The Partnership Interest of such Limited Partner
or Assignee subsequent to the exchange event shall be equal to the product of
the following: (i) the Partnership Interest of such Limited Partner or Assignee
immediately prior to the exchange event, multiplied by (ii) a fraction, the
numerator of which is the total Partnership Units owned by such Limited Partner
or Assignee immediately after the exchange event, and the denominator of which
is the total number of Partnership Units owned by such Limited Partner or
Assignee immediately prior to the exchange event. Notwithstanding the foregoing,
if a Limited Partner or Assignee owns Partnership Units and also owns
Partnership Interests issued pursuant to Section 4.3 or 4.7 above, which
Partnership Interests were not associated with Partnership Units, the portion of
the Partnership Interest of such Limited Partner or Assignee that represents the
Partnership Interests issued pursuant to Section 4.3 or 4.7 shall not be subject
to reduction pursuant to the provisions of this Section 8.8.B.

                                   ARTICLE IX
                     BOOKS, RECORDS, ACCOUNTING AND REPORTS

         Section 9.1  Records and Accounting

         The General Partner shall keep or cause to be kept at the principal
office of the Partnership appropriate books and records with respect to the
Partnership's business, including, without limitation, all books and records
necessary to provide to the Limited Partners any information, lists and copies
of documents required to be provided pursuant to Section 8.5 hereof. Any records
maintained by or on behalf of the Partnership in the regular course of its
business may be kept on, or be in the form of, punch cards, magnetic tape,
photographs, micrographics or any other information storage device, provided
that the records so maintained are convertible into clearly legible written form
within a reasonable period of time. The books of the Partnership shall be
maintained, for financial and tax reporting purposes, on an accrual basis in
accordance with generally accepted accounting principles.

         Section 9.2  Fiscal Year

         The fiscal year of the Partnership shall be the calendar year.

         Section 9.3  Reports

         As soon as practicable after the close of each fiscal quarter (other
than the last quarter of the fiscal year), the General Partner shall cause to be
mailed to each Limited Partner a quarterly report containing financial
statements of the Partnership, or of the Crescent Group if such statements are
prepared solely on a consolidated basis with the Crescent Group, for such fiscal
quarter, presented in accordance with generally accepted accounting principles.
As soon as practicable after the close of each fiscal year, the General Partner
shall cause to be mailed to each Limited Partner an annual report containing
financial statements of the Partnership, or of the Crescent Group




                                      -46-
<PAGE>   52

if such statements are prepared solely on a consolidated basis with the Crescent
Group, for such fiscal year, presented in accordance with generally accepted
accounting principles. The annual financial statements shall be audited by a
nationally recognized firm of independent public accountants selected by the
General Partner.

                                    ARTICLE X
                                   TAX MATTERS

         Section 10.1  Preparation of Tax Returns

         The General Partner shall arrange for the preparation and timely
filing of all returns of Partnership income, gains, deductions, losses and other
items required of the Partnership for federal, state and local income tax
purposes, and the delivery to the Limited Partners of all tax information
reasonably required by the Limited Partners for federal, state and local income
tax reporting purposes.

         Section 10.2  Tax Elections

         Except as otherwise provided herein, the General Partner shall, in its
sole and absolute discretion, determine whether to make any available election
or choose any available reporting method pursuant to the Code or state or local
tax law; provided, however, that the General Partner shall make the election
under Section 754 of the Code in accordance with applicable regulations
thereunder. The General Partner shall have the right to seek to revoke any such
election (including, without limitation, the election under Section 754 of the
Code) or change any reporting method upon the General Partner's determination in
its sole and absolute discretion that such revocation is in the best interests
of all of the Partners.

         Section 10.3 Tax Matters Partner

               A.     The General Partner shall be the "tax matters partner" of
the Partnership for federal income tax purposes. Pursuant to Section 6223(c)(3)
of the Code, upon receipt of notice from the IRS of the beginning of an
administrative proceeding with respect to the Partnership, the tax matters
partner shall furnish the IRS with the name, address and profits interest of
each of the Limited Partners, provided that such information is provided to the
Partnership by the Limited Partners.

               B.     The tax matters partner is authorized, but not required:

               (1)    to enter into any settlement with the IRS with respect to
                      any administrative or judicial proceedings for the
                      adjustment of Partnership items required to be taken into
                      account by a Partner for income tax purposes (such
                      administrative proceedings being referred to as a "tax
                      audit" and such judicial proceedings being referred to as
                      "judicial review"), and in the settlement agreement the
                      tax matters partner may expressly state that such
                      agreement shall bind all Partners, except that such
                      settlement agreement shall not bind

                      any Partner (i) who (within the time prescribed pursuant
                      to the Code and Regulations) files a statement with the
                      IRS providing that the tax matters partner shall not
                      have the authority to enter into a settlement agreement
                      on behalf of such Partner or (ii) who is a "notice
                      partner" (as defined in Section 6231 of the Code) or a
                      member of a "notice group" (as defined in Section
                      6223(b)(2) of the Code);

               (2)    in the event that a notice of a final administrative
                      adjustment at the Partnership level of any item required
                      to be taken into account by a Partner for tax purposes (a
                      "final adjustment") is mailed to the tax matters partner,
                      to seek judicial review of such final adjustment,
                      including the filing of a petition for readjustment with
                      the Tax Court or the United States Claims Court, or the
                      filing of a complaint for refund with the District Court
                      of the United States for the district in which the
                      Partnership's principal place of business is located;

               (3)    to intervene in any action brought by any other Partner
                      for judicial review of a final adjustment;

               (4)    to file a request for an administrative adjustment with
                      the IRS at any time and, if any part of such request is
                      not allowed by the IRS, to file an appropriate pleading
                      (petition or complaint) for judicial review with respect
                      to such request;

               (5)    to enter into an agreement with the IRS to extend the
                      period for assessing any tax which is attributable to any
                      item required to be taken into account by a Partner for
                      tax purposes, or an item affected by such item; and

               (6)    to take any other action on behalf of the Partners of the
                      Partnership in connection with any tax audit or judicial
                      review proceeding to the extent permitted by applicable
                      law or regulations.

         The taking of any action and the incurring of any expense by the tax
matters partner in connection with any such proceeding, except to the extent
required by law, is a matter in the sole and absolute discretion of the tax
matters partner and the provisions relating to indemnification of Indemnitees
set forth in Section 7.7 of this Agreement shall be fully applicable to the tax
matters partner in its capacity as such.

               C.     The tax matters partner shall receive no compensation for
its services. All third party costs and expenses incurred by the tax matters
partner in performing its duties as such (including legal and accounting fees)
shall be borne by the Partnership. Nothing herein shall be construed to restrict
the Partnership from engaging an accounting firm to assist the tax matters
partner in discharging its duties hereunder.

         Section 10.4 Organizational Expenses

         The Partnership shall elect to deduct expenses, if any, incurred by it
in organizing the Partnership ratably over a sixty (60)-month period as provided
in Section 709 of the Code.

         Section 10.5 Withholding

         Each Limited Partner hereby authorizes the Partnership to withhold from
or pay on behalf of or with respect to such Limited Partner any amount of
federal, state, local, or foreign taxes that the General Partner determines that
the Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such Limited Partner pursuant to this Agreement,
including, without limitation, any taxes required to be withheld or paid by the
Partnership pursuant to Sections 1441, 1442, 1445, or 1446 of the Code. Any
amount paid on behalf of or with respect to a Limited Partner shall constitute a
loan by the Partnership to such Limited Partner, which loan shall be repaid by
such Limited Partner within fifteen (15) days after notice from the General
Partner that such payment must be made unless (i) the Partnership withholds such
payment from a distribution which would otherwise be made to the Limited
Partner, or (ii) the General Partner determines, in its sole and absolute
discretion, that such payment may be satisfied out of the available funds of the
Partnership which would, but for such payment, be distributed to the Limited
Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii)
shall be treated as having been distributed to such Limited Partner. Each
Limited Partner hereby unconditionally and irrevocably grants to the Partnership
a security interest in such Limited Partner's Partnership Interest to secure
such Limited Partner's obligation to pay to the Partnership any amounts required
to be paid pursuant to this Section 10.5. In the event that a Limited Partner
fails to pay any amounts owed to the Partnership pursuant to this Section 10.5
when due, the General Partner may, in its sole and absolute discretion, elect to
make the payment to the Partnership on behalf of such defaulting Limited
Partner, and in such event shall be deemed to have loaned such amount to such
defaulting Limited Partner and, until repayment of such loan, shall succeed to
all rights and remedies of the Partnership as against such defaulting Limited
Partner (including, without limitation, the right to receive distributions). Any
amounts payable by a Limited Partner hereunder shall bear interest at the base
rate on corporate loans at large United States money center commercial banks, as
published from time to time in the Wall Street Journal, plus four percentage
points (but not higher than the maximum lawful rate) from the date such amount
is due (i.e., fifteen (15) days after demand) until such amount is paid in full.
Each Limited Partner shall take such actions as the Partnership or the General
Partner shall request in order to perfect or enforce the security interest
created hereunder.

                                   ARTICLE XI
                            TRANSFERS AND WITHDRAWALS

         Section 11.1 Transfer

               A.     The term "transfer," when used in this Article 11 with
respect to a Partnership Interest, shall be deemed to refer to a transaction by
which the General Partner purports




                                      -49-
<PAGE>   55

to assign its General Partnership Interest to another Person or by which a
Limited Partner purports to assign its Limited Partnership Interest to another
Person, and includes a sale, assignment, gift, pledge, encumbrance,
hypothecation, mortgage, exchange or any other disposition by law or otherwise.
The term "transfer" when used in this Article 11 does not include any exchange
of Partnership Units by a Limited Partner pursuant to Section 8.6.

               B.     No Partnership Interest shall be transferred, in whole or
in part, except in accordance with the terms and conditions set forth in this
Article 11. Any transfer or purported transfer of a Partnership Interest not
made in accordance with this Article 11 shall be null and void.

         Section 11.2 Transfer of Partnership Interests of the General Partner

               A.     The General Partner shall not withdraw from the
Partnership or transfer all or any portion of its interest in the Partnership
except in connection with a transaction described in Section 11.2.B or 11.2.C.

               B.     Crescent Equities shall not engage in any merger,
consolidation or other combination with or into another Person, or sale of all
or substantially all of its assets, or any reclassification, or recapitalization
or change of outstanding REIT Shares (other than a reincorporation, a
reorganization primarily for the purpose of changing domicile or converting to
corporate form, a change in par value, or from par value to no par value, or as
a result of a subdivision or combination as described in the definition of
"Exchange Factor," which require no consent of the Limited Partners under this
Agreement) ("Transaction"), unless the Transaction either:

               (1)    includes a merger of the Partnership or sale of
                      substantially all of the assets of the Partnership, as a
                      result of which all Limited Partners will receive for each
                      Partnership Unit an amount of cash, securities, or other
                      property equal to the product of the Exchange Factor and
                      the greatest amount of cash, securities or other property
                      paid to a holder of one REIT Share in consideration of one
                      REIT Share at any time during the period from and after
                      the date on which the Transaction is consummated, provided
                      that if, in connection with the Transaction, a purchase,
                      tender or exchange offer shall have been made to and
                      accepted by the holders of more than fifty percent (50%)
                      of the outstanding REIT Shares, the holders of Partnership
                      Units shall receive the greatest amount of cash,
                      securities, or other property which a Limited Partner
                      would have received had it exercised the Exchange Right
                      and received REIT Shares in exchange for all of its
                      Partnership Units immediately prior to the expiration of
                      such purchase, tender or exchange offer; or

               (2)    provides that the Partnership shall continue as a separate
                      entity and grants to the Limited Partners exchange rights
                      with respect to the ownership interests in the new entity
                      that are substantially equivalent to the Exchange Rights
                      provided for in Section 8.6.

               C.     Crescent Equities shall not transfer all or any portion
of its ownership interest in the General Partner; provided, however, that
Crescent Equities may liquidate the General Partner.

         Section 11.3 Transfer of Partnership Interests of Limited Partners
                      Other Than Crescent Equities

               A.     Subject to the provisions of Sections 11.3.C, 11.3.D,
11.3.E, 11.3.F and 11.3.G hereof, any Limited Partner other than Crescent
Equities may freely transfer all or any portion of its Partnership Interest. Any
transferee of a Limited Partnership Interest (whether such transferee is a
Substituted Limited Partner or an Assignee) shall also become the owner of any
Partnership Units associated with such Limited Partnership Interest, and shall
be entitled to exercise the Exchange Rights with respect to such Partnership
Units in accordance with the terms and conditions set forth in Section 8.6
above.

               B.     If a Limited Partner is Incapacitated, the executor,
administrator, trustee, committee, guardian, conservator or receiver of such
Limited Partner's estate shall have all the rights of a Limited Partner, but not
more rights than those enjoyed by other Limited Partners, for the purpose of
settling or managing the estate and such power as the Incapacitated Limited
Partner possessed to transfer all or any part of its interest in the
Partnership. The Incapacity of a Limited Partner, in and of itself, shall not
dissolve or terminate the Partnership.

               C.     The General Partner may prohibit any transfer otherwise
permitted under this Section 11.3 by a Limited Partner of its Partnership
Interest if, in the opinion of legal counsel to the Partnership, such transfer
would require filing of a registration statement under the Securities Act or
would otherwise violate any federal or state securities laws or regulations
applicable to the Partnership or the Partnership Interest.

               D.     No transfer by a Limited Partner of its Partnership
Interest may be made to any Person if (i) in the opinion of legal counsel for
the Partnership, it would result in the Partnership being treated as an
association taxable as a corporation for federal income tax purposes, or result
in a termination of the Partnership for federal income tax purposes, (ii) in the
opinion of the legal counsel for the Partnership, it would adversely affect the
ability of Crescent Equities to continue to qualify as a REIT or subject
Crescent Equities to any additional taxes under Section 857 or Section 4981 of
the Code, or (iii) the General Partner determines that such transfer is
effectuated through or, together with other similar transfers, could result in
the creation of an "established securities market" or a "secondary market (or
the substantial equivalent thereof)" or otherwise increase the likelihood that
the Partnership would be treated as a "publicly traded partnership" within the
meaning of Code Section 7704 and the related Notice 88-75, 1988-2 C.B. 386, and
Treasury Regulations Section 1.7704-1.

               E.     No transfer by a Limited Partner of its Partnership
Interest may be made (i) to any Person who lacks the legal right, power or
capacity to own a Partnership Interest, (ii) in violation of any provision of
any mortgage or trust deed (or the note or bond secured thereby) constituting a
Lien against an asset of the Partnership, (iii) in violation of applicable law,
or (iv) if



                                      -51-
<PAGE>   57

such transfer would, in the opinion of counsel to the Partnership, cause any
portion of the assets of the Partnership to constitute assets of any employee
benefit plan pursuant to Department of Labor regulations section 2510.2-101.

               F.     No transfer of a Limited Partnership Interest may be made
to a lender to the Partnership or any Person who is related (within the meaning
of Regulations Section 1.752-4(b)) to any lender to the Partnership whose loan
constitutes a Nonrecourse Liability, except with the consent of the General
Partner, which consent may be granted or withheld in the sole and absolute
discretion of the General Partner.

         Section 11.4 Substituted Limited Partners

               A.     Except as otherwise expressly provided in the last
sentence of this Section 11.4.A, no Limited Partner shall have the right to
substitute a transferee as a Limited Partner in its place without the consent of
the General Partner, which consent may be granted or withheld by the General
Partner in its sole and absolute discretion. The General Partner's failure or
refusal to permit a transferee of a Limited Partnership Interest to become a
Substituted Limited Partner shall not give rise to any cause of action against
the Partnership or any Partner. Notwithstanding anything to the contrary
contained above in this Section 11.4.A, if the transferee of a Limited
Partnership Interest is a Person listed on Exhibit E attached hereto, the
General Partner shall be required to admit such transferee as a Substituted
Limited Partner, provided that (i) the transfer of the Limited Partnership
Interest to such Person is not prohibited under the provisions of Sections
11.3.C through G hereof, and (ii) such transferee complies with the provisions
of the second sentence of Section 11.4.B hereof.

               B.     A transferee who has been admitted as a Substituted
Limited Partner in accordance with this Article 11 shall have all the rights and
powers and be subject to all the restrictions and liabilities of a Limited
Partner under this Agreement. The admission of any transferee as a Substituted
Limited Partner shall be subject to the transferee executing and delivering to
the Partnership an acceptance of all of the terms and conditions of this
Agreement (including, without limitation, the provisions of Section 2.4) and
such other documents or instruments as may be required to effect the admission.

               C.     Upon the admission of a Substituted Limited Partner, the
General Partner shall amend Exhibit A to reflect the name, address, number of
Partnership Units, and Partnership Interest of such Substituted Limited Partner
and to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.

         Section 11.5 Assignees

         If the General Partner, in its sole and absolute discretion, does not
consent to the admission of any permitted transferee under Section 11.3 as a
Substituted Limited Partner, as described in Section 11.4, such transferee shall
be considered an Assignee for purposes of this Agreement. An Assignee shall be
deemed to have had assigned to it, and shall be entitled to receive
distributions from the Partnership and the share of Net Income, Net Losses,
Recapture Income, and any




                                      -52-
<PAGE>   58

other items of income, gain, loss, deduction and credit of the Partnership
attributable to the Partnership Interest transferred to such transferee, but
shall not be entitled to vote such Partnership Interest on any matter presented
to the Limited Partners for a vote (such Partnership Interest being deemed to
have been voted on such matter in the same proportion as all other Partnership
Interests held by the Limited Partners are voted). In the event any such
transferee desires to make a further transfer of any such Partnership Interest,
such transferee shall be subject to all of the provisions of this Article 11 to
the same extent and in the same manner as any Limited Partner desiring to make a
transfer of a Partnership Interest.

         Section 11.6 General Provisions

               A.     No Limited Partner may withdraw from the Partnership other
than as a result of a permitted transfer of all of such Limited Partner's
Partnership Interest in accordance with this Article 11 or pursuant to an
exchange of its Partnership Interest under Section 8.6.

               B.     Any Limited Partner who shall transfer all of its
Partnership Interest in a permitted transfer pursuant to this Article 11 or
pursuant to an exchange of all of its Partnership Units under Section 8.6 shall
cease to be a Limited Partner.

               C.     If any Partnership Interest is exchanged pursuant to
Section 8.6 or transferred pursuant to this Article 11 at any time other than
the end of a fiscal year, Net Income, Net Loss, each item thereof and all other
items attributable to such interest for such fiscal year shall be allocated
between the transferor Partner and the transferee Partner in the same ratio as
the number of days in such fiscal year before and after such transfer, except
that gain or loss attributable to the sale or other disposition of all or any
substantial portion of the Partnership assets or to other extraordinary
non-recurring items shall be allocated to the owner of the Partnership Interest
as of the date of closing of the sale or other disposition, or, with respect to
other extraordinary non-recurring items, the date the profit is realized or the
loss is incurred, as the case may be. Solely for purposes of the allocations to
be made under the preceding sentence (but not for any other purpose), (i) any
Partnership Interest that is exchanged or otherwise transferred prior to the
eighth day of a month shall receive allocations under the preceding sentence as
if it had been transferred on the first day of the month, (ii) any Partnership
Interest that is exchanged or otherwise transferred on or after the eighth day
of a month and prior to the twenty-third day of such month shall receive
allocations under the preceding sentence as if it had been transferred on the
fifteenth day of the month, and (iii) any Partnership Interest that is exchanged
or otherwise transferred on or after the twenty-third day of a month shall
receive allocations under the preceding sentence as if it had been transferred
on the first day of the next succeeding month. All distributions of Available
Cash with respect to which the Partnership Record Date is before the date of
such transfer or exchange shall be made to the transferor Partner, and all
distributions of Available Cash thereafter shall be made to the transferee
Partner.

         Section 11.7 Acquisition of Partnership Interest by Partnership

         The Partnership may acquire, by purchase, redemption or otherwise, any
Partnership Interest or other interest of a Partner in the Partnership. Any
Partnership Interest or other interest




                                      -53-
<PAGE>   59

so acquired by the Partnership shall be deemed canceled. In the event that a
Partnership Interest is acquired by the Partnership pursuant to this Section
11.7, the Partnership Interest of each other existing Partner shall be
increased, as of the date of acquisition of such Partnership Interest by the
Partnership, such that the Partnership Interest of each Partner shall be equal
to the sum of (a) each Partner's existing Partnership Interest, plus (b) the
product obtained by multiplying (i) each Partner's existing Partnership Interest
by (ii) a fraction, the numerator of which is equal to the Partnership Interest
acquired by the Partnership and the denominator of which is equal to the result
obtained by subtracting (A) one minus (B) the Partnership Interest acquired by
the Partnership.

                                  ARTICLE XII
                              ADMISSION OF PARTNERS

         Section 12.1 Admission of Substituted General Partner

         A successor to all of the General Partner's General Partnership
Interest pursuant to Section 11.2 hereof who is proposed to be admitted as a
substituted General Partner shall be admitted to the Partnership as the General
Partner, effective simultaneously with such transfer. Any such transferee shall
carry on the business of the Partnership without dissolution. In each case, the
admission shall be subject to the substituted General Partner executing and
delivering to the Partnership an acceptance of all of the terms and conditions
of this Agreement and such other documents or instruments as may be required to
effect the admission.

         Section 12.2 Admission of Additional or Employee Limited Partners

               A.     After the admission to the Partnership of the Limited
Partners on the date hereof, a Person who makes a Capital Contribution to the
Partnership in accordance with Section 4.3 hereof or receives a Limited
Partnership Interest pursuant to Section 4.7 hereof shall be admitted to the
Partnership as an Additional Limited Partner or Employee Limited Partner, as the
case may be, only upon furnishing to the General Partner (i) evidence of
acceptance in form satisfactory to the General Partner of all of the terms and
conditions of this Agreement, including, without limitation, the power of
attorney granted in Section 2.4 hereof, and (ii) such other documents or
instruments as may be required in the discretion of the General Partner in order
to effect such Person's admission as an Additional Limited Partner or Employee
Limited Partner, as the case may be. The admission of any Person as an
Additional Limited Partner or Employee Limited Partner, as the case may be,
shall become effective on the date upon which the name of such Person is
recorded on the books and records of the Partnership, following the consent of
the General Partner to such admission.

               B.     If any Additional Limited Partner or Employee Limited
Partner is admitted to the Partnership at any time other than the end of a
fiscal year, Net Income, Net Loss, each item thereof and all other items for
such fiscal year shall be allocated among such Additional Limited Partner or
Employee Limited Partner and all other Partners by taking into account their
varying interests during such fiscal year in accordance with Section 706(d) of
the Code. For this purpose, Net Income, Net Loss, each item thereof and all
other items for such fiscal year shall be prorated based on the portion of the
taxable year that has elapsed prior to the admission of such Additional





                                      -54-
<PAGE>   60

Limited Partner or Employee Limited Partner, except that gain or loss
attributable to the sale or other disposition of all or any substantial portion
of the Partnership assets or to other extraordinary non-recurring items shall be
allocated to the Partners who own Partnership Interests as of the date of
closing of the sale or other disposition, or, with respect to other
extraordinary non-recurring items, the date the profit is realized or the loss
is incurred, as the case may be. All distributions of Available Cash with
respect to which the Partnership Record Date is before the date of admission of
such Additional Limited Partner or Employee Limited Partner shall be made solely
to Partners other than the Additional Limited Partner or Employee Limited
Partner, and all distributions of Available Cash thereafter shall be made to all
Partners including the Additional Limited Partner or Employee Limited Partner.

               C.     Greenbrier has executed and delivered to the General
Partner the Greenbrier Agreement. The General Partner, exercising its discretion
pursuant to Section 12.2.A hereof, hereby agrees that the Greenbrier Agreement
is the sole document required to effectuate the admission to the Partnership of
Greenbrier as an Additional Limited Partner. The Greenbrier Agreement contains
an "evergreen" provision so that it shall be deemed reexecuted and delivered to
the General Partner by Greenbrier if, as and whenever it shall acquire future
installments of Partnership Units under the Consultant Unit Agreement if, prior
to the acquisition of any such future installment, it shall have exchanged all
of its Partnership Units and consequently ceased to be a Limited Partner
pursuant to Section 11.6.B hereof. Accordingly, if, as and whenever Greenbrier
receives Partnership Units pursuant to the terms of the Consultant Unit
Agreement, the General Partner shall automatically admit Greenbrier as an
Additional Limited Partner without requiring any additional documentation from
Greenbrier, even if Greenbrier is not at that time a Limited Partner of the
Partnership.

         Section 12.3 Amendment of Agreement and Certificate of Limited
Partnership

         For the admission to the Partnership of any Partner in accordance with
the provisions of this Agreement, the General Partner shall take all steps
necessary and appropriate under the Act to amend the records of the Partnership
and, if necessary, to prepare as soon as practical an amendment of this
Agreement (including an amendment of Exhibit A) and, if required by law, shall
prepare and file an amendment to the Certificate and may for this purpose
exercise the power of attorney granted pursuant to Section 2.4 hereof.

                                  ARTICLE XIII
                           DISSOLUTION AND LIQUIDATION

         Section 13.1 Dissolution

         The Partnership shall not be dissolved by the admission of Substituted
Limited Partners, Additional Limited Partners or Employee Limited Partners, or
by the admission of a substituted General Partner in accordance with the terms
of this Agreement. Upon the withdrawal of the General Partner, any substituted
General Partner shall continue the business of the Partnership. The Partnership
shall dissolve, and its affairs shall be wound up, upon the first to occur of
any of the following ("Liquidating Events"):



                                      -55-
<PAGE>   61


               A.     the expiration of its term as provided in Section 2.5
hereof;

               B.     an event of withdrawal of the General Partner, as defined
in the Act (other than (i) a liquidation of the General Partner into Crescent
Equities, in which event Crescent Equities shall become the General Partner, or
(ii) an event of Bankruptcy), unless within ninety (90) days after the
withdrawal remaining Partners owning a majority-in-interest of the total
Partnership Interests of the remaining Partners agree in writing to continue the
business of the Partnership and to the appointment, effective immediately prior
to the date of withdrawal, of a substitute General Partner;

               C.     an election to dissolve the Partnership made in writing by
the General Partner;

               D.     entry of a decree of judicial dissolution of the
Partnership pursuant to the provisions of the Act;

               E.     the sale of all or substantially all of the assets and
properties of the Partnership, unless the General Partner elects to continue the
Partnership business for the purpose of the receipt and the collection of
indebtedness or the collection of other consideration to be received in exchange
for the assets of the Partnership (which activities shall be deemed to be part
of the winding up of the Partnership); or

               F.     a final and non-appealable judgment is entered by a court
with appropriate jurisdiction ruling that either Crescent Equities or the
General Partner is bankrupt or insolvent, or a final and non-appealable order
for relief is entered by a court with appropriate jurisdiction against either
Crescent Equities or the General Partner, in each case under any federal or
state bankruptcy or insolvency laws as now or hereafter in effect, unless prior
to the entry of such order or judgment remaining Partners owning a
majority-in-interest of the total Partnership Interests of the remaining
Partners agree in writing to continue the business of the Partnership and to the
appointment, effective as of a date prior to the date of such order or judgment,
of a substituted General Partner.

         Section 13.2 Winding Up

               A.     Upon the occurrence of a Liquidating Event, the
Partnership shall continue solely for the purposes of winding up its affairs in
an orderly manner, liquidating its assets (subject to the provisions of Section
13.2.B below), and satisfying the claims of its creditors and Partners. No
Partner shall take any action that is inconsistent with, or not necessary to or
appropriate for, the winding up of the Partnership's business and affairs. The
General Partner (or, in the event there is no remaining General Partner, any
Person elected by Limited Partners owning a majority-in-interest of the total
Partnership Interests of the Limited Partners (the "Liquidator")) shall be
responsible for overseeing the winding up and dissolution of the Partnership and
shall take full account of the Partnership's liabilities and property and the
Partnership property shall be liquidated as promptly as is consistent with
obtaining the fair market value thereof, and the proceeds






                                      -56-
<PAGE>   62

therefrom (which may, to the extent determined by the General Partner, include
shares of stock in Crescent Equities) shall be applied and distributed in the
following order:

               (1)    First, to the payment and discharge of all of the
                      Partnership's debts and liabilities to creditors other
                      than the Partners;

               (2)    Second, to the payment and discharge of all of the
                      Partnership's debts and liabilities to the Partners; and

               (3)    The balance, if any, to the General Partner and Limited
                      Partners in accordance with their positive Capital Account
                      balances, after giving effect to all contributions,
                      distributions, and allocations for all periods.

The General Partner shall not receive any additional compensation for any
services performed pursuant to this Article 13.

               B.     Notwithstanding the provisions of Section 13.2.A hereof
which require liquidation of the assets of the Partnership, but subject to the
order of priorities set forth therein, if prior to or upon dissolution of the
Partnership the Liquidator determines that an immediate sale of part or all of
the Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole and absolute discretion, defer for a
reasonable time the liquidation of any assets except those necessary to satisfy
liabilities of the Partnership (including to those Partners as creditors) and/or
distribute to the Partners, in lieu of cash, as tenants in common and in
accordance with the provisions of Section 13.2.A hereof, undivided interests in
such Partnership assets as the Liquidator deems not suitable for liquidation.
Any such distributions in kind shall be made only if, in the good faith judgment
of the Liquidator, such distributions in kind are in the best interest of the
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.

               C.     As part of the liquidation and winding-up of the
Partnership, a proper accounting shall be made of the Capital Account of each
Partner, including an analysis of changes to the Capital Account from the date
of the last previous accounting. Financial statements presenting such accounting
shall include a report of an independent certified public accountant selected by
the Liquidator.

               D.     As part of the liquidation and winding-up of the
Partnership, the Liquidator may sell Partnership assets (or assets owned by the
Subsidiary Corporations, the Management Company, or any other entity in which
the Partnership is an owner), at the best price and on the best terms and
conditions as the Liquidator in good faith believes are reasonably available at
the time.

         Section 13.3 Compliance with Timing Requirements of Regulations

         In the event the Partnership is "liquidated" within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant
to this Article 13 to the General Partner and Limited Partners who have positive
Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2).
If any Partner has a deficit balance in its Capital Account (after giving effect
to all contributions, distributions and allocations for all taxable years,
including the year during which such liquidation occurs), such Partner shall
have no obligation to make any contribution to the capital of the Partnership
with respect to such deficit, and such deficit shall not be considered a debt
owed to the Partnership or to any other Person for any purpose whatsoever. In
the discretion of the Liquidator, a pro rata portion of the distributions that
would otherwise be made to the General Partner and Limited Partners pursuant to
this Article 13 may be:

                  (i) distributed to a trust established for the benefit of the
General Partner and Limited Partners for the purposes of liquidating Partnership
assets, collecting amounts owed to the Partnership, and paying any contingent or
unforeseen liabilities or obligations of the Partnership or of the General
Partner arising out of or in connection with the Partnership. The assets of any
such trust shall be distributed to the General Partner and Limited Partners from
time to time, in the reasonable discretion of the Liquidator, in the same
proportions as the amount distributed to such trust by the Partnership would
otherwise have been distributed to the General Partner and Limited Partners
pursuant to this Agreement; or

                  (ii) withheld to provide a reasonable reserve for Partnership
liabilities (contingent or otherwise) and to reflect the unrealized portion of
any installment obligations owed to the Partnership, provided that such withheld
amounts shall be distributed to the General Partner and Limited Partners as soon
as practicable.

         Section 13.4 Deemed Distribution and Recontribution

         Notwithstanding any other provisions of this Article 13, in the event
the Partnership is liquidated within the meaning of Regulations Section
1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership's
property shall not be liquidated, the Partnership's liabilities shall not be
paid or discharged, and the Partnership's affairs shall not be wound up.
Instead, the Partnership shall be deemed to have distributed the Partnership
property in kind to the General Partner and Limited Partners, who shall be
deemed to have assumed and taken such property subject to all Partnership
liabilities, all in accordance with their respective Capital Accounts.
Immediately thereafter, the General Partner and Limited Partners shall be deemed
to have recontributed the Partnership property in kind to the Partnership, which
shall be deemed to have assumed and taken such property subject to all such
liabilities.

         Section 13.5 Rights of Limited Partners

         Except as otherwise provided in this Agreement, each Limited Partner
shall look solely to the assets of the Partnership for the return of its Capital
Contribution and shall have no right or power to demand or receive property
other than cash from the Partnership. No Limited Partner




                                      -58-
<PAGE>   64

shall have priority over any other Limited Partner as to the return of its
Capital Contributions, distributions, or allocations, except as permitted by
Section 8.7.C or otherwise expressly provided in this Agreement.

         Section 13.6 Documentation of Liquidation

         Upon the completion of the liquidation of the Partnership cash and
property as provided in Section 13.2 hereof, the Partnership shall be terminated
and the Certificate and all qualifications of the Partnership as a foreign
limited partnership in jurisdictions other than the State of Delaware shall be
canceled and such other actions as may be necessary to terminate the Partnership
shall be taken. The Liquidator shall have the authority to execute and record
any and all documents or instruments required to effect the dissolution,
liquidation and termination of the Partnership.

         Section 13.7 Reasonable Time for Winding-Up

         A reasonable time shall be allowed for the orderly winding-up of the
business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2 hereof, in order to minimize any losses otherwise
attendant upon such winding-up, and the provisions of this Agreement shall
remain in effect between the Partners during the period of liquidation.

         Section 13.8 Liability of the Liquidator

         The Liquidator shall be indemnified and held harmless by the
Partnership from and against any and all claims, demands, liabilities, costs,
damages and causes of action of any nature whatsoever arising out of or
incidental to the Liquidator's taking of any action authorized under or within
the scope of this Agreement; provided, however, that the Liquidator shall not be
entitled to indemnification, and shall not be held harmless, where the claim,
demand, liability, cost, damage or cause of action at issue arises out of:

               (1)    a matter entirely unrelated to the Liquidator's action or
                      conduct pursuant to the provisions of this Agreement; or

               (2)    the proven willful misconduct or gross negligence of the
                      Liquidator.

         Section 13.9 Waiver of Partition

         Each Partner hereby waives any right to a partition of the Partnership
property.

                                  ARTICLE XIV
                             AMENDMENT OF AGREEMENT

         Section 14.1 Amendments

               A.     Amendments to this Agreement may be proposed by the
General Partner. Except as provided in Section 14.1.B or 14.1.C, a proposed
amendment shall be adopted and be






                                      -59-
<PAGE>   65

effective as an amendment hereto if it is approved by the General Partner and
Limited Partners owning a majority-in-interest of the total Percentage Interests
of the Limited Partners.

               B.     Notwithstanding Section 14.1.A, the General Partner shall
have the power, without the Consent of the Limited Partners, to amend this
Agreement as may be required to facilitate or implement any of the following
purposes:

               (1)    to add to the obligations of the General Partner or
                      surrender any right or power granted to the General
                      Partner or any Affiliate of the General Partner for the
                      benefit of the Limited Partners;

               (2)    to reflect the admission, substitution, termination, or
                      withdrawal of Partners in accordance with this Agreement
                      (including, without limitation, adjustments to Exhibit A
                      to reflect such events, as set forth in Section 4.1.B
                      hereof); and

               (3)    to reflect a change that is of an inconsequential nature
                      and does not adversely affect the Limited Partners in any
                      material respect, or to cure any ambiguity, correct or
                      supplement any provision in this Agreement not
                      inconsistent with law or with other provisions, or make
                      other changes with respect to matters arising under this
                      Agreement that will not be inconsistent with law or with
                      the provisions of this Agreement.

               C.     Notwithstanding anything to the contrary contained in
Section 14.1.A hereof, this Agreement shall not be amended without the prior
written consent of each Partner adversely affected if such amendment would (i)
convert a Limited Partner's interest in the Partnership into a general partner's
interest, (ii) modify the limited liability of a Limited Partner, (iii) alter
rights of the Partner to receive distributions pursuant to Article 5, or the
allocations specified in Article 6 (except as permitted pursuant to Sections
4.2, 4.3, 4.6, 4.7, 8.7 and Section 14.1.B(3) hereof), (iv) alter or modify the
Exchange Rights set forth in Section 8.6, or the right set forth in Section
11.2.C, (v) cause the termination of the Partnership prior to the time set forth
in Sections 2.5 or 13.1, or (vi) amend this Section 14.1.C. Further, no
amendment may alter the restrictions on the General Partner's authority set
forth in Section 7.3 without the consent of all Limited Partners.

<PAGE>   66

                      (1) Organization. If such Partner is not a natural person,

and in good standing in the jurisdictions in which it does business.

                      (2) Due Authorization; Binding Agreement. This Agreement
has been duly executed and delivered by such Partner, or an authorized
representative of such Partner, and constitutes a legal, valid and binding
obligation of such Partner, enforceable against such Partner in accordance with

                      (3) Consents and Approvals. No consent, waiver, approval
or authorization of, or filing, registration or qualification with, or notice
to, any governmental unit or any other person is required to be made, obtained
or given by such Partner in connection with the execution, delivery and
performance of this Agreement other than consents, waivers, approvals or
authorizations which have been obtained prior to the date hereof.

                      (4) No Conflict with Other Documents or Violation of Law.
The execution of this Agreement by such Partner and such Partner's performance
of the transactions contemplated herein will not violate any document,
instrument, agreement, stipulation, judgment, order, or any applicable federal,
state or local law, ordinance or regulation to which such Partner is a party or
by which such Partner is bound.

               B.     Each Limited Partner represents and warrants that its
Limited Partnership Interest is being acquired for its own account and not with
a view to the distribution or other sale thereof, except in a transaction which
is exempt from registration under the Securities Act or registered thereunder.
Any distribution or other sale of the Limited Partnership Interest of such
Limited Partner shall be subject to the provisions of Section 11.3 hereof. Such
Limited Partner further represents and warrants to the Partnership and the other
Partners as follows:

                      (1) If such Limited Partner is a corporation, partnership
or a Massachusetts business trust or similar business trust, it has not been
formed for the specific purpose of acquiring the Limited Partnership Interest,
and has total assets in excess of Five Million Dollars ($5,000,000);

                      (2) If such Limited Partner is an individual, he or she
had an individual income in excess of $200,000 in each of the two most recent
tax years or joint income with his or her spouse in excess of $300,000 in each
of those years and has a reasonable expectation of reaching at least the same
income level in the current year;

                      (3) Such Limited Partner is a sophisticated investor with
the capacity to protect its own interests in investments of this nature, and is
capable of evaluating the merits and risks of an investment in the Limited
Partnership Interest;

                      (4) Such Limited Partner has had an opportunity to ask
questions and receive answers concerning the investment in the Limited
Partnership Interest, and has all of the information deemed by it to be
necessary or appropriate to evaluate the investment in the Limited Partnership
Interest and the risks and merits thereof;

                      (5) Such Limited Partner is aware of the following:




                                      -61-
<PAGE>   67

                          (i) An investment in the Limited Partnership Interest
is speculative, with no assurance of any income therefrom;

                          (ii) No federal or state agency has made any finding
or determination as to the fairness of the acquisition, or any recommendation or
endorsement of such acquisition;

                          (iii) Transferability of the Limited Partnership
Interest is restricted and, accordingly, it may not be possible for such Limited
Partner to liquidate the Limited Partnership Interest in case of emergency; and

                          (iv) With respect to the tax aspects of an investment
in the Limited Partnership Interest, such Limited Partner in making this
acquisition is not relying to any degree upon the advice of Crescent Equities or
the Partnership, or any Person affiliated therewith, but rather solely upon its
own legal, financial and tax advisors.

         Notwithstanding anything to the contrary contained in this Agreement,
all claims, disputes and controversies between the parties hereto (including,
without limitation, any claims, disputes and controversies between the
Partnership and any one or more of the Partners and any claims, disputes and
controversies among any two or more Partners) arising out of or in connection
with this Agreement or the Partnership created hereby, relating to the validity,
construction, performance, breach, enforcement or termination thereof, or
otherwise, shall be resolved by binding arbitration in the State of Texas, in
accordance with this Article 16 and, to the extent not inconsistent herewith,
the Expedited Procedures and Commercial Arbitration Rules of the American
Arbitration Association.

         Section 16.2 Procedures

         Any arbitration called for by this Article 16 shall be conducted in
accordance with the following procedures:

               (1)    The Partnership or any partner (the "Requesting Party")
may demand arbitration pursuant to Section 16.1 hereof at any time by giving
written notice of such demand (the "Demand Notice") to all other Partners and
(if the Requesting Party is not the Partnership) to the Partnership, which
Demand Notice shall describe in reasonable detail the nature of the claim,
dispute or controversy.

               (2)    Within fifteen (15) days after the giving of a Demand
Notice, the Requesting Party, on the one hand, and each of the other Partners
and/or the Partnership against whom the claim has been made or with respect to
which a dispute has arisen (collectively, the "Responding Party"), on the other
hand, shall select and designate in writing to the other party one reputable,
disinterested individual deemed competent to arbitrate the claim, dispute or
controversy (a




                                      -62-
<PAGE>   68

"Qualified Individual") willing to act as an arbitrator of the claim, dispute or
controversy. Within fifteen (15) days after the foregoing selections have been
made, the arbitrators so selected shall jointly select a third Qualified
Individual willing to act as an arbitrator of the claim, dispute or controversy.
In the event that the two arbitrators initially selected are unable to agree on
a third arbitrator within the second fifteen (15) day period referred to above,
then, on the application of either party, the American Arbitration Association
shall promptly select and appoint a Qualified Individual to act as the third
arbitrator. The three arbitrators selected pursuant to this Section 16.2(2)
shall constitute the arbitration panel for the arbitration in question.

               (3)    The presentations of the parties hereto in the arbitration
proceeding shall be commenced and completed within sixty (60) days after the
selection of the arbitration panel pursuant to Section 16.2(2) above, and the
arbitration panel shall render its decision in writing within thirty (30) days
after the completion of such presentations. Any decision concurred in by any two
(2) of the arbitrators shall constitute the decision of the arbitration panel,
and unanimity shall not be required.

               (4)    The arbitration panel shall have the discretion to include
in its decision a direction that all or part of the attorneys' fees and costs of
any party or parties and/or the costs of such arbitration be paid by any other
party or parties. On the application of a party before or after the initial
decision of the arbitration panel, and proof of its attorneys' fees and costs,
the arbitration panel shall order the other party to make any payments directed
pursuant to the preceding sentence.

               (5)    Notwithstanding anything to the contrary contained above
in this Section 16.2, if either party fails to select a Qualified Individual to
act as an arbitrator for such party with the fifteen (15) day time period set
forth in the first sentence of Section 16.2(2), the Qualified Individual
selected by the other party shall serve as sole arbitrator under this Section
16.2 in lieu of the arbitration panel. Such sole arbitrator shall have all of
the rights and duties of the arbitration panel set forth above in this Section
16.2.

         Section 16.3 Binding Character

         Any decision rendered by the arbitration panel pursuant to this Article
16 shall be final and binding on the parties hereto, and judgment thereon may be
entered by any state or federal court of competent jurisdiction

         Section 16.4 Exclusivity

         Arbitration shall be the exclusive method available for resolution of
claims, disputes and controversies described in Section 16.1 hereof, and the
Partnership and its Partners stipulate that the provisions hereof shall be a
complete defense to any suit, action, or proceeding in any court or before any
administrative or arbitration tribunal with respect to any such claim,
controversy or dispute. The provisions of this Article 16 shall survive the
dissolution of the Partnership.

February 19, 1998, the issuance date of Series A Preferred Shares by Crescent

Partnership Units to Crescent Equities.

     (a) Crescent Equities shall have a zero percentage Partnership Interest

Crescent Equities with respect to the Series A Preferred Partnership Units, or
(iii) alter the distribution, redemption, conversion or liquidation rights of
the Series A Preferred Partnership Units as set forth in paragraphs 2(b) through

     (b) Notwithstanding Section 5.2 of the Effective Agreement, and prior to
any distributions of Available Cash under such provision, the General Partner
shall cause distributions of Available Cash to be made quarterly in cash on the
15th day, or if not a Business Day, the next succeeding Business Day, of

accrued, unpaid quarterly distributions to the holders of Series A Preferred
Shares) to Crescent Equities in an amount equal to the amount that is required
to be distributed by Crescent Equities on that date to the holders of Series A
Preferred Shares.

     (c) Notwithstanding Sections 6.1.A and B of the Effective Agreement

         (i) Each year, after giving effect to the special allocations set
forth in Section 1 of Exhibit C to the Effective Agreement, gross income of the
Partnership shall be allocated first to Crescent Equities until the cumulative
amount allocated under this paragraph 2(c)(i) to Crescent Equities for the
current year and all prior years is equal to the cumulative amount for the
current year and all prior years of the distributions made to Crescent Equities
under paragraph 2(b) above and the portion of the distributions made to Crescent
Equities under paragraph 2(d) below (if any) that exceeds $25 per Series A

assets of the Partnership, which shall be allocated as set forth in paragraphs
2(c)(ii) and (iii) below) shall be allocated as set forth in Sections 6.1.A and
B of the Effective Agreement.

         (ii) The gain of the Partnership from a sale or other disposition of
all or substantially all of the assets of the Partnership shall be allocated
among the Partners as follows: (A) first, to Crescent Equities in the amount
necessary to cause its Capital Account balance to be equal to the liquidation
preference payable by Crescent Equities on the outstanding Series A Preferred
Shares (the "Liquidation Preference") (i.e., a liquidation payment of $25 per
Series A Preferred Partnership Unit, necessary, plus and accrued, unpaid
quarterly distribution thereon), (B) second, to the Partners in the amounts
necessary, and in the ratio of such amounts, to cause the Capital Account
balance of Crescent Equities in excess of the liquidation Preference and the
Capital Account of each other Partner to be in the same ratio as their
respective Partnership Interests, and (iii) thereafter, to all of the Partners

all or substantially all of the assets of the Partnership shall be allocated

positive Capital Account balances, in the amounts necessary, and in the ratio of
such amounts, so as to cause the positive Capital Account Balance of Crescent

                                      -4-
<PAGE>   77

Equities to equal the Liquidation Preference and the positive Capital Account
balance of each other Partner to equal zero (or, if there is insufficient loss
to accomplish this result, loss shall be allocated in a manner so as to cause
the positive Capital Account balance of Crescent Equities in excess of the
Liquidation Preference and the positive Capital Account balance of each other
Partner to be in the same ratio as their respective Partnership Interests), (B)
second, to Crescent Equities, until its positive Capital Account balance equals
zero, and (C) thereafter, to the Partners in proportion to their respective
Partnership Interests.

     (d) In the event that Crescent Equities exercises its redemption right
with respect to the Series A Preferred Shares, the Partnership shall
concurrently redeem a corresponding amount of Series A Preferred Partnership
Units at the same redemption price paid by Crescent Equities for the Series A
Preferred Shares (i.e., a redemption payment of $25 per Series A Preferred
Partnership Unit, plus any accrued, unpaid quarterly distribution thereon).

     (e) Upon exercise of any conversion right with respect to Series A
Preferred Shares, (i) Crescent Equities shall, as of the date on which the
conversion is consummated, be deemed to have contributed to the Partnership as
Contributed Funds pursuant to Section 4.2.A(2) of the Effective Agreement an
amount equal to the Value (computed as of the Business Day immediately
preceding the date on which such conversion is consummated) of the REIT Shares
delivered by Crescent Equities to such holder of Series A Preferred Shares, (ii)
the Partnership Interests of Crescent Equities and the other Limited Partners
shall be adjusted as set forth in Section 4.2 of the Effective Agreement, and
(iii) a corresponding portion of Series A Preferred Partnership Units shall be
retired.

     3. Except as the context may otherwise require, any terms used in this
First Amendment which are defined in the Effective Agreement shall have the
same meaning for purposes of this First Amendment as in the Effective
Agreement.

     4. Except as herein amended, the Effective Agreement is hereby ratified,
confirmed, and reaffirmed for all purposes and in all respects.

     IN WITNESS WHEREOF, the undersigned has executed this First Amendment as

      (a) Crescent Equities shall have a zero percentage Partnership Interest

liability of Crescent Equities with respect to the Series B Preferred
Partnership Units, or (iii) alter the distribution, redemption, conversion or
liquidation rights of the Series B Preferred Partnership Units as set forth in

shall cause distributions of Available Cash to be made in cash, on any date on
which Crescent Equities makes a distribution of accrued, unpaid quarterly
distributions to the holders of Series A Preferred Shares or of extraordinary
cash distributions to the holders of Series B Preferred Shares, to Crescent
Equities in an amount equal to the amount that is required to be distributed by
Crescent Equities on that date to the holders of Series A Preferred Shares and
Series B Preferred Shares. Notwithstanding Section 5.4 of the Effective
Agreement, the General Partner shall cause the Partnership to make non-cash
distributions of assets to Crescent Equities on any date on which Crescent

Preferred Shares.


      (c) Notwithstanding Sections 6.1.A and B of the Effective Agreement:


          (i) Each year, after giving effect to the special allocations set
forth in Section 1 of Exhibit C to the Effective Agreement, gross income of the
Partnership shall be allocated first to Crescent Equities until the cumulative
amount allocated under this paragraph 1(c)(i) to Crescent Equities for the
current year and all prior years is equal to the cumulative amount for the
current year and all prior years of the sum of (A) the distributions made to
Crescent Equities under paragraph 1(b) above, and (B) the portion of the
distributions made to Crescent Equities under paragraph 2(d) of the First
Amendment (if any) that exceeds $25 per Series A Preferred Partnership Unit.
Any remaining Net Profits or Net Losses (other than gain or loss from a sale or
other disposition of all or substantially all of the assets of the Partnership,
which shall be allocated as set forth in paragraphs 1(c)(ii) and (iii) below)
shall be allocated as set forth in Sections 6.1.A and B of the Effective
Agreement.


          (ii) The gain of the Partnership from a sale or other disposition of
all or substantially all of the assets of the Partnership shall be allocated
among the Partners as follows: (A) first, to Crescent Equities in the amount
necessary to cause its Capital Account balance to be equal to the liquidation
preferences payable by Crescent Equities on the outstanding Series A Preferred
Shares and Series B Preferred Shares (the "Liquidation Preferences") (i.e., a
liquidation payment of $25 per Series A Preferred Partnership Unit, plus any
accrued, unpaid quarterly distribution thereon, and a liquidation payment of

any accrued, unpaid extraordinary distribution thereon, subject to reduction on
a pro rata basis (as more fully set forth in the respective "Statements of
Designation" for the Series A Preferred Shares and the Series B Preferred
Shares) to the extent that there are insufficient funds to pay the
aforementioned liquidation preferences in full), (B) second, to the Partners in
the amounts necessary, and in the ratio of such amounts, to cause the Capital
Account balance of Crescent Equities in excess of the Liquidation Preferences
and the Capital Account of each other Partner to be in the same ratio as their
respective Partnership Interests, and (iii) thereafter, to all of the Partners
in proportion to their respective Partnership Interests.


           (iii) The loss of the Partnership from a sale or other disposition
of all or substantially all of the assets of the Partnership shall be allocated
among the Partners as follows: (A) first, to the Partners, if any, having
positive Capital Account balances, in the amounts necessary, and in the ratio
of such amounts, so as to cause the positive Capital Account Balance of
Crescent Equities to equal the Liquidation Preferences and the positive Capital
Account balance of each other Partner to equal zero (or, if there is
insufficient loss to accomplish this result, loss shall be allocated in a
manner so as to cause the positive Capital Account balance of Crescent Equities
in excess of the Liquidation Preference and the positive Capital Account
balance of each other Partner to be in the same ratio as their respective
Partnership Interests), (B) second, to Crescent Equities, until its positive
Capital Account balance equals zero, and (C) thereafter, to the Partners in
proportion to their respective Partnership Interests.


      (d) In the event that Crescent Equities exercises its redemption right
with respect to the Series B Preferred Shares and pays the redemption price in
cash, the Partnership shall concurrently redeem a corresponding amount of
Series B Preferred Partnership Units at the same redemption price paid by
Crescent Equities for the Series B Preferred Shares.


      (e) Upon exercise of any conversion right with respect to Series B
Preferred Shares or upon any redemption of Series B Preferred Shares in
exchange for REIT shares, (i) Crescent Equities shall, as of the date on which
the conversion (or redemption, as the case may be) is consummated, be deemed to
have contributed to the Partnership as Contributed Funds pursuant to Section
4.2.A(2) of the Effective Agreement an amount equal to the Value (computed as
of the Business Day immediately preceding the date on which such conversion (or
redemption, as the case may be) is consummated) of the REIT Shares delivered by
Crescent Equities to such holder of Series B Preferred Shares, (ii) the
Partnership Interests of Crescent Equities and the other Limited Partners shall
be adjusted as set forth in Section 4.2 of the Effective Agreement, and (iii) a
corresponding portion of Series B Preferred Partnership Units shall be retired.


      (f) Notwithstanding anything to the contrary contained in paragraph 2(e)
of the First Amendment or in paragraph 1(e) of this Fifth Amendment, to the
extent that Crescent Equities pays cash to the holder of Series A Preferred
Shares (or Series B Preferred Shares, as the case may be) in lieu of fractional
shares upon conversion of such Series A Preferred Shares (or Series B Preferred
Shares, as the case may be) to REIT Shares, such cash payment shall be treated
as a redemption of the corresponding portion of the Series A Preferred Shares
(or Series B Preferred Shares, as the case may be) in accordance with paragraph
2(d) of the First Amendment (or paragraph 1(d) of this Fifth Amendment, as the
case may be).


      2. In order to reflect the issuance of Series B Preferred Partnership
Units, Exhibit A to the Effective Agreement is hereby deleted in its entirety
and replaced with the Exhibit A attached to this Fifth Amendment and made a
part hereof.

                          the Employee Limited Partner shall, as of the date on
                          which the grant of the Partnership Units is made, be

                          number of Partnership Units delivered to such Employee
                          Limited Partner, multiplied by (ii) the Exchange

                          above; provided that, for purposes of calculating the

                          Partnership Interest Value" under Section 4.3, the
                          "Value" of a REIT Share shall be the "closing price"
                          (as such term is defined in the definition of the term
                          "Value" in Article I hereof) of a REIT Share as of the
                          date on which the grant of Partnership Units is made.

                      (2) If the admission is made in connection with the
                          exercise of an option to purchase Partnership Units by
                          an Employee Limited Partner, (a) the Employee Limited
                          Partner shall, as

                          4.3 hereof an amount equal to the fair market value
                          of the Partnership Units delivered to such Employee
                          Limited Partner (computed by calculating the product
                          of the following three items: (i) the number of
                          Partnership Units delivered to such Employee Limited
                          Partner, multiplied by (ii) the Exchange Factor,

                          is defined in the definition of the term "Value" in
                          Article I hereof, of a REIT Share on the date on
                          which the option to purchase Partnership Units is
                          exercised) and (b) the General Partner's Partnership
                          Interest shall remain unchanged, and the Partnership
                          Interests of Crescent Equities and the other Limited
                          Partners shall be adjusted as set forth in Section
                          4.3, based on the amount deemed to be contributed by
                          the Employee Limited Partner as determined pursuant
                          to clause (a) above; provided that, for purposes of
                          calculating the "Deemed Value of the Partnership" and
                          the "Deemed Partnership Interest Value" under Section
                          4.3, the "Value" of a REIT Share shall be the
                          "closing price" (as such term is defined in the
                          definition of the term "Value" in Article I hereof)
                          of a REIT Share as of the date on which the option to
                          purchase Partnership Units is exercised.

                  3.  Except as the context may otherwise require, any terms
         used in this Thirteenth Amendment which are defined in the Effective
         Agreement shall have the same meaning for purposes of this Thirteenth
         Amendment as in the Effective Agreement.

                  4.  Except as herein amended, the Effective Agreement is
         hereby ratified, confirmed, and reaffirmed for all purposes and in all
         respects.
