         SECTION 1.  DEFINITIONS AND RULES OF INTERPRETATION.

         Section 1.1.  Definitions.  The following terms shall have the
meanings set forth in this Section l or elsewhere in the provisions of this
Agreement referred to below:

counsel as may be approved by the Agent.

         Agreement.  This Fifth Amended and Restated Revolving Credit
Agreement, including the Schedules and Exhibits hereto.

         Applicable Margin.  On any date that the higher of the Implied Ratings

an Investment Grade Rating, the Applicable Margin for Eurodollar Rate Loans
shall be as set forth below based on the higher of Implied Ratings issued by
either of the Rating Agencies:

                Rating                           LIBOR Rate Loans
                ------                           ----------------
          <S>                                    <C>
          BBB+/Baa1 or better                          0.90%

               BBB/Baa2                               1.050%

               BBB-/Baa3                               1.20%

In the event that either of the Rating Agencies issues an Implied Rating for
the Borrower that is an Investment Grade Rating, or in the event of any change

the Borrower's Implied Rating, after having obtained an Investment Grade
Rating, shall cease at any time to be an Investment Grade Rating by either of
the Rating Agencies (but subject to the provisions within the definition of the

seeking an Investment Grade Rating from the other of the Rating Agencies, the
Borrower shall be entitled to the benefit of the rate reductions described
above; provided that if the Borrower shall have obtained an Investment Grade

         SECTION 2.  THE REVOLVING CREDIT FACILITY.

         Section 2.1.  Commitment to Lend.  Subject to the terms and conditions
set forth in this Agreement, each of the Banks severally agrees to lend to the
Borrower, and the Borrower may borrow (and repay and reborrow) from time to
time between the Closing Date and the Maturity Date, upon notice by the
Borrower to the Agent given in accordance with Section 2.6, such sums as are
requested by the Borrower for the purposes set forth in Section 2.9 (but
subject to the limitations set forth in Section 2.9) up to a maximum aggregate
principal amount outstanding (after giving effect to all amounts requested) at
any one time equal to such Bank's Commitment; provided, that, in all events no
Default or Event of Default shall have occurred and be continuing and the
Borrower's financial statements as required pursuant to Section 2.6(iii) shall
demonstrate compliance with all covenants set forth therein; and provided,
further, that the outstanding principal amount of the Loans (after giving
effect to all amounts requested) shall not at any time exceed the Total
Commitment.  The Loans shall be made pro rata in accordance with each Bank's
Commitment Percentage.  Each request for a Loan hereunder shall constitute a
representation and warranty by the Borrower that all of the conditions set
forth in Section 10 and Section 11, in the case of the initial Loan, and
Section 11, in the case of all other Loans, have been satisfied on the date of
such request (except as otherwise permitted in Paragraph 4 of the form of Loan
Request with respect to warranties and representations).  No Bank shall have
any obligation to make Loans to the Borrower in the maximum aggregate principal
amount outstanding of more than the principal face amount of its Note.
Notwithstanding anything herein to the contrary, the Banks shall have no
obligation to make Loans to the Borrower in the maximum aggregate principal
amount outstanding of more than $750,000,000.00, provided that after BankBoston
sells down its present Commitment to $100,000,000.00, the Total Commitment
shall be increased up to a maximum of $850,000,000.00 as and when one or more
Banks shall acquire from BankBoston all or a portion of the additional
Commitment of $100,000,000.00.

         Section 2.2.  Facility Fee.  The Borrower agrees to pay to the Agent
for the accounts of the Banks in accordance with their respective Commitment
Percentages a facility fee calculated at the rate of one-fourth of one percent
(0.25%) per annum on the daily amount by which the Total Commitment exceeds the
outstanding principal amount of Loans during each calendar quarter or portion
thereof commencing on the date hereof and ending on the Maturity Date.  The
facility fee shall be payable quarterly in arrears on the fifth day of each
calendar quarter for the immediately preceding calendar quarter or portion
thereof, or on any earlier date on which the Commitments shall be reduced or
shall terminate as provided in Section 2.3, with a final payment on the
Maturity Date.  Any payment due under this Section 2.2 shall be prorated for
any partial calendar quarter.





                                      -17-
<PAGE>   24
         Section 2.3.  Reduction of Commitment.  The Borrower shall have the
right at any time and from time to time upon five Business Days' prior written
notice to the Agent to reduce by $5,000,000 or an integral multiple of $100,000
in excess thereof or to terminate entirely the unborrowed portion of the
Commitments, whereupon the Commitments of the Banks shall be reduced pro rata
in accordance with their respective Commitment Percentages of the amount
specified in such notice or, as the case may be, terminated, any such reduction
to be without penalty (unless such reduction requires repayment of a Eurodollar
Rate Loan).   Promptly after receiving any notice of the Borrower delivered
pursuant to this Section 2.3, the Agent will notify the Banks of the substance
thereof.  Upon the effective date of any such reduction or termination, the
Borrower shall pay to the Agent for the respective accounts of the Banks the
full amount of any facility fee under Section 2.2 then accrued on the amount of
the reduction.  No reduction or termination of the Commitment may be
reinstated.  Notwithstanding the foregoing, unless the Commitments are
terminated in full, in no event shall the aggregate Commitments be reduced to
less than $375,000,000.00.

         Section 2.4.  Notes.  The Loans shall be evidenced by separate
promissory notes of the Borrower in substantially the form of Exhibit A hereto
(collectively, the "Notes"), dated of even date with this Agreement and
completed with appropriate insertions.  One Note shall be payable to the order
of each Bank in the principal amount equal to such Bank's Commitment or, if
less, the outstanding amount of all Loans made by such Bank, plus interest
accrued thereon, as set forth below (provided that, without increasing the
Commitment of BankBoston, the initial Note delivered to BankBoston shall be in
the principal amount equal to the sum of BankBoston's Commitment and the
remaining Commitment of $100,000,000.00).   The Borrower irrevocably authorizes
each Bank to make or cause to be made, at or about the time of the Drawdown
Date of any Loan or at the time of receipt of any payment of principal thereof,
an appropriate notation on such Bank's Record reflecting the making of such
Loan or (as the case may be) the receipt of such payment.  The outstanding
amount of the Loans set forth on such Bank's Record shall be prima facie
evidence of the principal amount thereof owing and unpaid to such Bank, but the
failure to record, or any error in so recording, any such amount on such Bank's
Record shall not limit or otherwise affect the obligations of the Borrower
hereunder or under any Note to make payments of principal of or interest on any
Note when due.  By delivery of the Notes, there shall not be deemed to have
occurred, and there has not otherwise occurred, any payment, satisfaction or
novation of the Indebtedness evidenced by the "Notes" described in the Amended
Credit Agreement, which Indebtedness is instead allocated among the Banks as of
the date hereof and evidenced by the Notes and their respective Commitment
Percentages, and the Banks shall as of the date hereof make such adjustments to
the outstanding loans of such Banks so that such outstanding Loans are
consistent with their respective Commitment Percentages.

         Section 2.5.  Interest on Loans.

                 (a)      Each Base Rate Loan shall bear interest for the
period commencing with the Drawdown Date thereof and ending on the date on
which such Base Rate Loan is paid in full or is converted to a Eurodollar Rate
Loan from a Base Rate Loan at the Base Rate.





                                      -18-
<PAGE>   25
                 (b)      Each Eurodollar Rate Loan shall bear interest for the
period commencing with the Drawdown Date thereof and ending on the last day of
the Interest Period with respect thereto at the rate per annum equal to the sum
of the Applicable Margin plus the Eurodollar Rate determined for such Interest
Period.

                 (c)      The Borrower promises to pay interest on each Loan in
arrears on each Interest Payment Date with respect thereto.

                 (d)      Base Rate Loans and Eurodollar Rate Loans may be
converted to Loans of the other Type as provided in Section 4.1.

         Section 2.6.  Requests for Loans.  The Borrower (i) shall notify the
Agent of a potential request for a Loan as soon as possible prior to the
Borrower's proposed Drawdown Date, and (ii) shall give to the Agent written
notice in the form of Exhibit B hereto (or telephonic notice confirmed in
writing in the form of Exhibit B hereto) of each Loan requested hereunder (a
"Loan Request") no later than 10:00 a.m. three (3) Business Days prior to the
proposed Drawdown Date.  The Agent shall promptly notify each of the Banks
following the receipt of a Loan Request, but in any event no later than 2:00
p.m. three (3) Business Days prior to the proposed Drawdown Date.  Borrower
shall not make a Loan Request more frequently than three times each month.
Each such notice shall specify with respect to the requested Loan the proposed
principal amount, Drawdown Date, Interest Period (if applicable) and Type.
Each such notice shall also contain (i) a statement as to the purpose for which
such advance shall be used (which purpose shall be in accordance with the terms
of Section 2.9), (ii) a certification by the chief financial or chief
accounting officer of the General Partner that the Borrower is and will be in
compliance with all covenants under the Loan Documents after giving effect to
the making of such Loan, (iii) a Compliance Certificate prepared using the
financial statements of the Borrower most recently provided or required to be
provided to the Agent under Section 6.4 or Section 7.4 adjusted in the best
good faith estimate of the Borrower to give effect to the proposed advance and
incorporating the operating performance of any asset to be acquired, and (iv)
the Guarantor's Compliance Certificate prepared using the financial statements
of Crescent Guarantor most recently provided or required to be provided to the
Agent pursuant to the  Guaranty adjusted in the best good faith estimate of
Crescent Guarantor to the date of the proposed advance.  Promptly upon receipt
of any such notice, the Agent shall notify each of the Banks thereof.  Except
as provided in this Section 2.6, each such Loan Request shall be irrevocable
and binding on the Borrower and shall obligate the Borrower to accept the Loan
requested from the Banks on the proposed Drawdown Date, provided that, in
addition to the Borrower's other remedies against any Bank which fails to
advance its proportionate share of a requested Loan, such Loan Request may be
revoked by the Borrower by notice received by the Agent no later than the
Drawdown Date if any Bank fails to advance its proportionate share of the
requested Loan in accordance with the terms of this Agreement, provided further
that the Borrower shall be liable in accordance with the terms of this
Agreement to any Bank which is prepared to advance its proportionate share of
the requested Loan for any costs, expenses or damages incurred by such Bank as
a result of the Borrower's election to revoke such Loan Request (the
"Revocation Costs").  Nothing herein shall prevent the Borrower from seeking
recourse against any Bank that fails to advance its proportionate share of a
requested Loan as required by this Agreement.  The





                                      -19-
<PAGE>   26
Borrower may, without any liability for the payment of the Revocation Costs or
other cost or penalty, revoke a Loan Request by delivering notice thereof to
each of the Banks no later than 3:00 p.m. three (3) Business Days prior to the
Drawdown Date.  Each Loan Request shall be (a) for a Base Rate Loan in a
minimum aggregate amount of $1,000,000 or an integral multiple of $100,000 in
excess thereof, or (b) for a Eurodollar Rate Loan in a minimum aggregate amount
of $2,000,000 or an integral multiple of $100,000 in excess thereof; provided,
however, that there shall be no more than five (5) Eurodollar Rate Loans
outstanding at any one time.

         Section 2.7.  Funds for Loans.

                 (a)      Not later than 11:00 a.m. (Boston time) on the
proposed Drawdown Date of any Loans, each of the Banks will make available to
the Agent, at the Agent's Head Office, in immediately available funds, the
amount of such Bank's Commitment Percentage of the amount of the requested
Loans which may be disbursed pursuant to Section 2.1.  Upon receipt from each
Bank of such amount, and upon receipt of the documents required by Section 10
and Section 11 and the satisfaction of the other conditions set forth therein,
to the extent applicable, the Agent will make available to the Borrower the
aggregate amount of such Loans made available to the Agent by the Banks by wire
transfer in accordance with Borrower's instructions.  The failure or refusal of
any Bank to make available to the Agent at the aforesaid time and place on any
Drawdown Date the amount of its Commitment Percentage of the requested Loans to
the extent it is obligated to fund such Loan hereunder shall not relieve any
other Bank from its several obligation hereunder to make available to the Agent
the amount of such other Bank's Commitment Percentage of any requested Loans,
including any additional Loans that may be requested by the Borrower subject to
the terms and conditions hereof to provide funds to replace those not advanced
by the Bank so failing or refusing, provided that the Borrower may by notice
received by the Agent no later than the Drawdown Date refuse to accept any Loan
which is not fully funded in accordance with the Borrower's Loan Request
subject to the terms of Section 2.6 (except that such refusal shall not relieve
the Borrower of its obligation to pay the Revocation Costs); provided further
that no Bank shall be obligated to advance any amount in excess of the limits
set forth in Section 2.1.  In the event of any such failure or refusal, the
Banks not so failing or refusing shall be entitled to a priority position as
against the Bank or Banks so failing or refusing for such Loans as provided in
Section 12.4.

                 (b)      Unless Agent shall have been notified by any Bank
prior to the applicable Drawdown Date that such Bank will not make available to
Agent such Bank's pro rata share of a proposed Loan, Agent may in its
discretion assume that such Bank has made such Loan available to Agent in
accordance with the provisions of this Agreement and Agent may, if it chooses,
in reliance upon such assumption make such Loan available to Borrower, and such
Bank shall be liable to the Agent for the amount of such advance.

         Section 2.8.  Intentionally Omitted.

         Section 2.9.  Use of Proceeds.  The Borrower will use the proceeds of
the Loans solely to provide short-term financing (a) for the acquisition of fee
interests in Real Estate which is utilized principally for Class A office
space, behavioral healthcare facilities and/or hotel/resort properties





                                      -20-

which are of institutional quality or other income-producing real estate
reasonably satisfactory to the Majority Banks, subject to the limitations in
Section 9.9, (b) for working capital purposes, (c) for the acquisition of
non-income producing land assets or real estate assets which are held in fee
simple or in any form other than undivided fee simple ownership (such as
cotenancy interests, leasehold interests, partnership interests, shares of
stock in corporations owning real estate, or through mortgages or participation
interests in or assignments of mortgages), subject however to the limitations
in Section 9.9, and (d) for such other purposes as the Majority Banks in their
discretion from time to time may agree to in writing.  Without the consent of
the Majority Banks, in no event may any amount advanced under the Loan be used
directly or indirectly (i) to pay dividends or other distributions to any
partner or member of the Borrower, the Crescent Guarantor or the shareholders
of the Crescent Guarantor or (ii) except as expressly permitted in Section 8.9,
with respect to the obligations described in Schedule 8.1(h) or with respect to
the Investments described in Section 8.3(k) and (l), to make advances, loans,
Investments or other contributions to, or in any other manner "downstream"
into, Crescent Real Estate Funding I, L.P., Crescent Real Estate Funding II,
L.P., Crescent Real Estate Funding III, L.P., Crescent Real Estate Funding IV,
L.P., Crescent Real Estate Funding V, L.P., Crescent Real Estate Funding VI,
L.P., Crescent Real Estate Funding VII, L.P. or any other Subsidiary or
Investment Partnership of the Borrower whether now existing or hereafter
formed.  Without the consent of the Majority Banks, except with respect to the
development of Phase II at the project commonly referred to as "The Avallon"
(and the potential development of Phase III at the Avallon), tenant
improvements and the renovation or demolition and construction of the "Frost
Bank Garage" to be constructed at the northeast corner of the intersection of
Lavaca Street and Ninth Street in Austin, Texas, on land acquired by the
Borrower in connection with the acquisition of the Frost Bank Plaza Building,
the Surtran Garage at Continental Plaza, the convention hotel at Houston
Center, an office building near The Crescent and an office building near
Washington Harbor in Washington, D.C. as permitted pursuant to Section 8.9, no
portion of the proceeds of the Loan shall be used to develop or construct new
commercial real estate projects or for the substantial renovation or
rehabilitation of commercial real estate projects.

         SECTION 3.  REPAYMENT OF THE LOANS.

         Section 3.1.  Stated Maturity.  The Borrower promises to pay on the
Maturity Date and there shall become absolutely due and payable on the Maturity
Date, all of the Loans outstanding on such date, together with any and all
accrued and unpaid interest thereon.

         Section 3.2.  Mandatory Prepayments.  The Borrower promises to pay
principal of the Loans prior to stated maturity, as follows:

                 (a)      If at any time the aggregate outstanding principal
         amount of the Loans exceeds the Total Commitment, then the Borrower
         shall immediately upon demand from Agent pay the amount of such excess
         to the Agent for the respective accounts of the Banks for application
         to the Loans (it being acknowledged that in the event the Borrower
         makes such payment as provided herein, the Borrower shall not be in
         default of Section 9.3).

                 (b)      All of the Borrower's interest in the gross proceeds
         of each and every sale or refinancing of real estate assets of the
         Borrower and its Subsidiaries and Investment Partnerships (whether
         held directly or indirectly but excluding Borrower's interest in the
         gross proceeds of sales or refinancings of real estate assets by
         Subsidiaries and Investment Partnerships whose primary business is the
         subdivision and sale of residential land) provided such gross proceeds
         are in an amount in excess of $10,000,000.00 (provided further that
         the exclusion of sales with gross proceeds equal to or less than
         $10,000,000.00 shall be capped at $25,000,000.00 per year), less all
         reasonable costs, expenses and commissions paid to unrelated parties
         and less any Indebtedness (other than the Obligations) secured by such
         asset to be satisfied as a part of such sale or refinance, shall be
         promptly paid by the Borrower to the Agent for the account of the
         Banks as a prepayment of the Loans to the extent of the outstanding
         balance of the Loans; provided that, (x) so long as (i) there has been
         no acceleration of the maturity of the Obligations pursuant to Section
         12.1, (ii) no Event of Default under Section 12.1(a), (b), (d), (g),
         (h), (i), (j), (k), (l), (m), (n), and (o) has occurred and is
         continuing, or (iii) no breach of the covenants contained in Section
         8.1, Section 8.2, Section 8.3 or Section 8.7 has occurred and is
         continuing, the Borrower shall not as a result of this Section 3.2(b)
         be required to reduce the principal balance of the Loans to less than
         $50,000,000.00; and (y) with respect to the Borrower's interest in the
         gross proceeds of a sale or refinancing of real estate assets of a
         Subsidiary or Investment Partnership in which the Borrower does not
         own a majority (by number of votes or controlling interests) of the
         outstanding Voting Interests, the Borrower shall pay such gross
         proceeds to the Agent for the account of the Banks as soon as
         distributed to the Borrower by such Subsidiary or Investment
         Partnership.

                 Section 3.3.  Optional Prepayments.  The Borrower shall have
         the right, at its election, to prepay the outstanding amount of the
         Loans, as a whole or in part, at any time without penalty or premium;
         provided, that the full or partial prepayment of the outstanding
         amount of any Eurodollar Rate Loans pursuant to this Section 3.3 may
         be made only on the last day of the Interest Period relating thereto
         except as otherwise required pursuant to Section 4.7.  The Borrower
         shall give the Agent, no later than 10:00 a.m., Boston time, at least
         three (3) Business Days prior written notice of any prepayment
         pursuant to this Section 3.3, in each case specifying the proposed
         date of payment of Loans and the principal amount to be paid.

         Section 3.4.  Partial Prepayments.  Each partial prepayment of the
Loans under Section 3.2 and Section 3.3 shall be in the minimum amount of
$500,000.00 or an integral multiple of $100,000 in excess thereof (unless the
Loans are being prepaid in full), shall be accompanied by the payment of
accrued interest on the principal prepaid to the date of payment and, after
payment of such interest, shall be applied, in the absence of instruction by
the Borrower, first to the principal of Base Rate Loans and then to the
principal of Eurodollar Rate Loans.

         Section 3.5.  Effect of Prepayments.  Amounts of the Loans prepaid
under Section 3.2 and Section 3.3 prior to the Maturity Date may be reborrowed

shall cause all gross proceeds of each and every Debt Offering and Equity
Offering, less all reasonable costs, fees, expenses, underwriting commissions,
fees and discounts incurred in connection therewith, to be promptly paid by the

to the extent of the outstanding balance of the Loans; provided that, subject
to the limitations contained in Section 3.2(b) above, the Borrower shall not as
a result of this Section 3.6 be required to reduce the principal balance of the
Loans to less than $50,000,000.00.

         SECTION 4.  CERTAIN GENERAL PROVISIONS.

         Section 4.1.  Conversion Options.

                 (a)      The Borrower may elect from time to time to convert
any outstanding Loan to a Loan of another Type and such Loan shall thereafter
bear interest as a Base Rate Loan or a Eurodollar Rate Loan, as applicable;
provided that (i) with respect to any such conversion of a Eurodollar Rate Loan
to a Base Rate Loan, the Borrower shall give the Agent at least three Business
Days' prior written notice of such election, and such conversion shall only be
made on the last day of the Interest Period with respect to such Eurodollar
Rate Loan; (ii) with respect to any such conversion of a Base Rate Loan to a
Eurodollar Rate Loan, the Borrower shall give the Agent at least four
Eurodollar Business Days' prior written notice of such election and the
Interest Period requested for such Loan, the principal amount of the Loan so
converted shall be in a minimum aggregate amount of $2,000,000 or an integral
multiple of $100,000 in excess thereof and, after giving effect to the making
of such Loan, there shall be no more than five (5) Eurodollar Rate Loans
outstanding at any one time; and (iii) no Loan may be converted into a
Eurodollar Rate Loan when any Default or Event of Default has occurred and is
continuing.  All or any part of the outstanding Loans of any Type may be
converted as provided herein, provided that no partial conversion shall result
in a Base Rate Loan in an aggregate principal amount of less than $1,000,000 or
a Eurodollar Rate Loan in an aggregate principal amount of less than $2,000,000
and that the aggregate principal amount of each Loan shall be in an integral
multiple of $100,000.  On the date on which such conversion is being made, each
Bank shall take, to the extent it deems it necessary to do so, such action as
is necessary to transfer its Commitment Percentage of such Loans to its
Domestic Lending Office or its Eurodollar Lending Office, as the case may be.
Each Conversion Request relating to the conversion of a Base Rate Loan to a
Eurodollar Rate Loan shall be irrevocable by the Borrower.

                 (b)      Any Loan may be continued as such Type upon the
expiration of an Interest Period with respect thereto by compliance by the
Borrower with the terms of Section 4.1; provided that no Eurodollar Rate Loan
may be continued as such when any Default or Event of Default has occurred and
is continuing, but shall be automatically converted to a Base Rate Loan on the
last day of the Interest Period relating thereto ending during the continuance
of any Default or Event of Default.





                                      -23-
<PAGE>   30
                 (c)      In the event that the Borrower does not notify the
Agent of its election hereunder with respect to any Loan, such Loan shall be
automatically converted to a Base Rate Loan at the end of the applicable
Interest Period.

         Section 4.2.  Closing Fee.  The Borrower has paid to BankBoston
certain closing fees pursuant to an Agreement Regarding Fees dated of even date
herewith among the Borrower and BankBoston.  BankBoston has paid to the Banks a
closing fee in accordance with their separate agreement.

         Section 4.3.  Agent's Fee.  The Borrower shall pay to the Agent, for
the Agent's own account, an Agent's fee calculated at the rate of $50,000.00

day of each calendar quarter for the immediately preceding calendar quarter or
portion thereof.  The Agent's fee for any partial calendar quarter shall be
prorated.

         Section 4.4.  Funds for Payments.

                 (a)      All payments of principal, interest, facility fees,
Agent's fees, closing fees and any other amounts due hereunder or under any of
the other Loan Documents shall be made to the Agent, for the respective
accounts of the Banks and the Agent, as the case may be, at the Agent's Head
Office, not later than 3:00 p.m. (Boston time) on the day when due, in each
case in immediately available funds.  To the extent funds are available in such
account, the Agent is hereby authorized to charge the account of the Borrower
with BankBoston, on the dates when the amount thereof shall become due and
payable, with the amounts of the principal of and interest on the Loans and all
fees, charges, expenses and other amounts owing to the Agent and/or the Banks
under the Loan Documents.

                 (b)      All payments by the Borrower hereunder and under any
of the other Loan Documents shall be made without setoff or counterclaim and
free and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions or
conditions of any nature now or hereafter imposed or levied by any jurisdiction
or any political subdivision thereof or taxing or other authority therein
unless the Borrower is compelled by law to make such deduction or withholding.
If any such obligation is imposed upon the Borrower with respect to any amount
payable by it hereunder or under any of the other Loan Documents, the Borrower
will pay to the Agent, for the account of the Banks or (as the case may be) the
Agent, on the date on which such amount is due and payable hereunder or under
such other Loan Document, such additional amount in Dollars as shall be
necessary to enable the Banks or the Agent to receive the same net amount which
the Banks or the Agent would have received on such due date had no such
obligation been imposed upon the Borrower.  The Borrower will deliver promptly
to the Agent certificates or other valid vouchers for all taxes or other
charges deducted from or paid with respect to payments made by the Borrower
hereunder or under such other Loan Document.

         Section 4.5.  Computations.  All computations of interest on the Loans
and of other fees to the extent applicable shall be based on a 360-day year and
paid for the actual number of days elapsed.  Except as otherwise provided in
the definition of the term "Interest Period" with respect to Eurodollar Rate
Loans, whenever a payment hereunder or under any of the other Loan Documents
becomes due on a day that is not a Business Day, the due date for such payment
shall be extended to the next succeeding Business Day, and interest shall
accrue during such extension.  The outstanding amount of the Loans as reflected
on the records of the Agent from time to time shall be considered prima facie
evidence of such amount.

         Section 4.6.  Inability to Determine Eurodollar Rate.  In the event
that, prior to the commencement of any Interest Period relating to any
Eurodollar Rate Loan, the Agent shall determine in the exercise of its good
faith business judgment that adequate and reasonable methods do not exist for
ascertaining the Eurodollar Rate for such Interest Period, the Agent shall
forthwith give notice of such determination (which shall be conclusive and
binding on the Borrower and the Banks) to the Borrower and the Banks.  In such
event (a) any Loan Request with respect to Eurodollar Rate Loans shall be
automatically withdrawn and shall be deemed a request for Base Rate Loans and
(b) each Eurodollar Rate Loan will automatically, on the last day of the then
current Interest Period thereof, become a Base Rate Loan, and the obligations
of the Banks to make Eurodollar Rate Loans shall be suspended until the Agent
determines in the exercise of its good faith business judgment that the
circumstances giving rise to such suspension no longer exist, whereupon the
Agent shall so notify the Borrower and the Banks.

         Section 4.7.  Illegality.  Notwithstanding any other provisions
herein, if any present or future law, regulation, treaty or directive or the
interpretation or application thereof shall make it unlawful, or any central
bank or other governmental authority having jurisdiction over a Bank or its
Eurodollar Lending Office shall assert that it is unlawful, for any Bank to
make or maintain Eurodollar Rate Loans, such Bank shall forthwith give notice
of such circumstances to the Agent and the Borrower and thereupon (a) the
commitment of the Banks to make Eurodollar Rate Loans or convert Loans of
another type to Eurodollar Rate Loans shall forthwith be suspended and (b) the
Eurodollar Rate Loans then outstanding shall be converted automatically to Base
Rate Loans on the last day of each Interest Period applicable to such
Eurodollar Rate Loans or within such earlier period as may be required by law.

         Section 4.8.  Additional Interest.  If any Eurodollar Rate Loan or any
portion thereof is repaid or is converted to a Base Rate Loan for any reason on
a date which is prior to the last day of the Interest Period applicable to such
Eurodollar Rate Loan, the Borrower will pay to the Agent upon demand for the
account of the Banks in accordance with their respective Commitment
Percentages, in addition to any amounts of interest otherwise payable
hereunder, any amounts required to compensate the Banks for any losses, costs
or expenses which may reasonably be incurred as a result of such payment or
conversion, including, without limitation, an amount equal to daily interest
for the unexpired portion of such Interest Period on the Eurodollar Rate Loan
or portion thereof so repaid or converted at a per annum rate equal to the
excess, if any, of (a) the interest rate calculated on the basis of the
Eurodollar Rate applicable to such Eurodollar Rate Loan (including any spread
over such Eurodollar Rate) minus (b) the yield obtainable by the





                                      -25-

Agent upon the purchase of debt securities customarily issued by the Treasury
of the United States of America which have a maturity date most closely
approximating the last day of such Interest Period (it being understood that
the purchase of such securities shall not be required in order for such amounts
to be payable).

         Section 4.9.  Additional Costs, Etc.  Notwithstanding anything herein
to the contrary, if any present or future applicable law, which expression, as
used herein, includes statutes, rules and regulations thereunder and legally
binding interpretations thereof by any competent court or by any governmental
or other regulatory body or official with appropriate jurisdiction charged with
the administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon
or otherwise issued to any Bank or the Agent by any central bank or other
fiscal, monetary or other authority (whether or not having the force of law),
shall:

                 (a)      subject any Bank or the Agent to any tax, levy,
impost, duty, charge, fee, deduction or withholding of any nature with respect
to this Agreement, the other Loan Documents, such Bank's Commitment or the
Loans (other than taxes based upon or measured by the income or profits of such
Bank or the Agent), or

                 (b)      materially change the basis of taxation (except for
changes in taxes on income or profits) of payments to any Bank of the principal
of or the interest on any Loans or any other amounts payable to any Bank under
this Agreement or the other Loan Documents, or

                 (c)  impose or increase or render applicable any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar
requirements (whether or not having the force of law) against assets held by,
or deposits in or for the account of, or loans by, or commitments of an office
of any Bank, or

                 (d)      impose on any Bank or the Agent any other conditions
or requirements with respect to this Agreement, the other Loan Documents, the
Loans, such Bank's Commitment, or any class of loans or commitments of which
any of the Loans or such Bank's Commitment forms a part; and the result of any
of the foregoing is

                          (i)     to increase the cost to any Bank of making,
funding, issuing, renewing, extending or maintaining any of the Loans or such
Bank's Commitment, or

                          (ii)    to reduce the amount of principal, interest
or other amount payable to such Bank or the Agent hereunder on account of such
Bank's Commitment or any of the Loans, or

                          (iii)   to require such Bank or the Agent to make any
payment or to forego any interest or other sum payable hereunder, the amount of
which payment or foregone interest or other sum is calculated by reference to
the gross amount of any sum receivable or deemed received by such Bank or the
Agent from the Borrower hereunder,





                                      -26-
<PAGE>   33
then, and in each such case, the Borrower will, within thirty (30) days of
demand made by such Bank or (as the case may be) the Agent at any time and from
time to time and as often as the occasion therefor may arise, pay to such Bank
or the Agent such additional amounts as such Bank or the Agent shall determine
in good faith to be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or other sum.  Each
Bank and the Agent in determining such amounts may use any reasonable averaging
and attribution methods, generally applied by such Bank or the Agent.
Notwithstanding the foregoing, the Borrower shall have the right, in lieu of
making the payment referred to in this Section 4.9, to prepay the Loan of the
applicable Bank within thirty (30) days of such demand and avoid the payment of
the amounts otherwise due under this Section 4.9, provided, however, that the
Borrower shall be required to pay together with such prepayment of the Loan all
other costs, damages and expenses otherwise due under Section 4.8 of this
Agreement as a result of such prepayment, and following such prepayment, the
Total Commitment shall be reduced by the amount of the Loan so prepaid, and the
Commitment Percentages of the remaining Banks shall be adjusted based on the
percentage that each Bank's Commitment bears to the adjusted Total Commitment.

         Section 4.10.  Capital Adequacy.  If after the date hereof any Bank
reasonably determines that (a) the adoption of or change in any law, rule,
regulation or guideline regarding capital requirements for banks or bank
holding companies or any change in the interpretation or application thereof by
any governmental authority charged with the administration thereof, or (b)
compliance by such Bank or its parent bank holding company with any guideline,
request or directive of any such entity regarding capital adequacy (whether or
not having the force of law), has the effect of reducing the return on such
Bank's or such holding company's capital as a consequence of such Bank's
commitment to make Loans hereunder to a level below that which such Bank or
holding company could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's or such holding company's then existing
policies with respect to capital adequacy and assuming the full utilization of
such entity's capital) by any amount deemed by such Bank to be material, then
such Bank may notify the Borrower thereof.  The Borrower agrees to pay to such
Bank the amount of such reduction in the return on capital as and when such
reduction is determined, upon presentation by such Bank of a statement of the
amount setting forth the Bank's calculation thereof.  In determining such
amount, such Bank may use any reasonable averaging and attribution methods.

         Section 4.11.  Indemnity of Borrower.  The Borrower agrees to
indemnify each Bank and to hold each Bank harmless from and against any loss,
cost or expense that such Bank may sustain or incur as a consequence of (a)
default by the Borrower in payment of the principal amount of or any interest
on any Eurodollar Rate Loans as and when due and payable, including any such
loss or expense arising from interest or fees payable by such Bank to lenders
of funds obtained by it in order to maintain its Eurodollar Rate Loans, or (b)
default by the Borrower in making a borrowing or conversion after the Borrower
has given (or is deemed to have given) a Loan Request or a Conversion Request
(excluding, however, any Loan Request that pursuant to Section 2.6 may be
revoked without penalty and the deemed withdrawal of a Loan Request pursuant to
Section 4.6), or (c) default by the Borrower in making the payments or
performing its obligations under Sections 4.8, 4.9, 4.10, 4.12 or 4.13.

         Section 4.12.  Interest on Overdue Amounts; Late Charge.  Overdue
principal and (to the extent permitted by applicable law) interest on the Loans
and all other overdue amounts payable hereunder or under any of the other Loan
Documents shall bear interest payable on demand at a rate per annum equal to
four percent (4.0%) above the Base Rate until such amount shall be paid in full
(after as well as before judgment), or if such rate shall exceed the maximum
rate permitted by law, then at the maximum rate permitted by law.  In addition,
the Borrower shall pay a late charge equal to three percent (3%) of any amount
of interest and/or principal payable on the Loans or any other amounts payable
hereunder or under the Loan Documents, which is not paid within ten days of the
date when due.

         Section 4.13.  Certificate.  A certificate, prepared in good faith by
a Bank consistent with such Bank's practice in calculating such amounts,
setting forth any amounts payable pursuant to Section 4.8, Section 4.9, Section
4.10, Section 4.11 or Section 4.12 and a brief explanation of such amounts
which are due, submitted by any Bank or the Agent to the Borrower, shall be
conclusive in the absence of manifest error.

         Section 4.14.  Limitation on Interest.  Notwithstanding anything in
this Agreement to the contrary, all agreements between the Borrower and the
Banks and the Agent, whether now existing or hereafter arising and whether
written or oral, are hereby limited so that in no contingency, whether by
reason of acceleration of the maturity of any of the Obligations or otherwise,
shall the interest contracted for, charged or received by the Banks exceed the
maximum amount permissible under applicable law.  If, from any circumstance
whatsoever, interest would otherwise be payable to the Banks in excess of the
maximum lawful amount, the interest payable to the Banks shall be reduced to
the maximum amount permitted under applicable law; and if from any circumstance
the Banks shall ever receive anything of value deemed interest by applicable
law in excess of the maximum lawful amount, an amount equal to any excessive
interest shall be applied to the reduction of the principal balance of the
Obligations and to the payment of interest or, if such excessive interest
exceeds the unpaid balance of principal of the Obligations, such excess shall
be refunded to the Borrower.  All interest paid or agreed to be paid to the
Banks shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full period until payment in full of the
principal of the Obligations (including the period of any renewal or extension
thereof) so that the interest thereon for such full period shall not exceed the
maximum amount permitted by applicable law.  This section shall control all
agreements between the Borrower and the Banks and the Agent.

         SECTION 5.  COLLATERAL SECURITY AND GUARANTY.

         Section 5.1.  Security. The Banks have agreed to make the Loans to the
Borrower on an unsecured basis.  Notwithstanding the foregoing, the Obligations
shall be guaranteed by Guarantor pursuant to the Guaranty.

         Section 5.2.  Subsidiary Guarantors.  In the event that the Borrower
shall after the Closing Date have an Investment in any Subsidiary in which
Borrower directly or indirectly owns a one hundred percent (100%) interest and
in which the Borrower has control over all major day-to-day decisions with
respect to the operation of such entity, Borrower shall cause such Subsidiary
to





                                      -28-
<PAGE>   35
execute and deliver to Agent a Guaranty, and such Subsidiary shall become a
Guarantor hereunder.  The Borrower shall further cause such Subsidiary to
become a party to the Contribution Agreement.  The organizational agreements of
such Subsidiary or such other resolutions or consents satisfactory to Agent
shall specifically authorize such Subsidiary to guarantee the Obligations.  The
Borrower shall further cause all representations, covenants and agreements in
the Loan Documents with respect to Guarantors to be true and correct with
respect to such Guarantor.  In connection with the delivery of such Guaranty,
the Borrower shall deliver to the Agent such organizational documents,
resolutions, consents, opinions and other documents and instruments as the
Agent may reasonably require.

         SECTION 6.  REPRESENTATIONS AND WARRANTIES.

         The Borrower represents and warrants to the Agent and the Banks as

board that, if adversely determined, might, either in any case or in the
aggregate, materially adversely affect the properties, assets, financial
condition or business of such Person or materially impair the right of such
Person to carry on business substantially as now conducted by it, or result in

partner, officer, trustee, director, or any such employee has a substantial
interest or is an officer, director, trustee or partner, unless such contract,
agreement or other arrangement is an arms-length arrangement with terms
comparable to those which would be obtained from an unaffiliated Person or is
otherwise approved by the Agent.  For the purposes of this Section 6.14, a

each Employee Benefit Plan, Multiemployer Plan or Guaranteed Pension Plan.

minimum funding standard under Section 412 of the Code in respect of any
Employee Benefit Plan, Multiemployer Plan or Guaranteed Pension Plan, (b)
failed to make any contribution or payment to any Employee Benefit Plan,
Multiemployer Plan or Guaranteed Pension Plan, or made any amendment to any
Employee Benefit Plan, Multiemployer Plan or Guaranteed Pension Plan, which has
resulted or could result in the imposition of a Lien or the posting of a bond
or other security under ERISA or the Code, or (c) incurred any liability under
Title IV of ERISA other than a liability to the PBGC for premiums under Section
4007 of ERISA.  None of the Real Estate constitutes a "plan asset" of any
Employee Plan, Multiemployer Plan or Guaranteed Pension Plan.

complaint, or legal or administrative proceeding (in each case, contingent or
otherwise) arising out of any third party's incurrence of costs, expenses,
losses or damages of any kind whatsoever in connection with the release of
Hazardous Substances.

                 (c)      To the best of the Borrower's knowledge, or in the

treatment or disposal facilities maintaining valid permits as required under
all applicable Environmental Laws, which transporters and facilities have been
and are, to the best of the Borrower's knowledge, operating in compliance with
such permits and applicable Environmental Laws.

                 (d)      Neither the Borrower, the General Partner, the
Borrower's Subsidiaries, nor any Real Estate is subject to any applicable

engineer in accordance with customary standards which discloses that such
property is not in violation of the representations and covenants set forth in
this Agreement, unless satisfactory remediation actions are being taken.  There
are no unpaid or outstanding real estate or other taxes or assessments on or
against any property of the Borrower or any of its Subsidiaries or Investment

business or financial condition of the Borrower.  None of the property of
Borrower or its Subsidiaries or Investment Partnerships is now damaged as a

which individually or in the aggregate would have any materially adverse effect
on the business or financial condition of the Borrower.

Borrower and the Guarantor are able to pay their respective debts as they
become due, and the Borrower and the Guarantor have sufficient capital to carry
on their respective businesses.

         Section 6.24.  Other Debt.  None of  the Borrower, the Guarantor nor
any of their respective Subsidiaries nor any of the Investment Partnerships is
in default of the payment of any Indebtedness or the terms of any other
mortgage, deed of trust, security agreement, financing agreement, indenture or
other material lease or agreement to which any of them is a party which relates
to Indebtedness or other obligations which individually or in the aggregate
exceed $1,000,000.00.  None of the Borrower or the Guarantor is a party to or
bound by any agreement, instrument or indenture that may require the

Subsidiary Guarantors have executed and delivered the Contribution Agreement,
and the Contribution Agreement constitutes the valid and legally binding
obligations of such parties enforceable against them in accordance with the
terms and provisions thereof, except as enforceability is limited by
bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting generally the enforcement of creditors' rights and except to the
extent that availability of the remedy of specific performance or injunctive
relief is subject to the discretion of the court before which any proceeding
therefor may be brought.

Investment described in Section 8.3(i) within any fiscal quarter of the
Borrower, such notice to be submitted together with the Compliance Certificate
provided or required to be provided to the Banks under Section 7.4 with respect
to such fiscal quarter.  The Compliance Certificate shall with respect to any
proposed or completed sale, encumbrance, refinance or transfer be adjusted in
the best good-faith estimate of the Borrower to give effect to such sale,
encumbrance, refinance or transfer and demonstrate that no Default or Event of
Default with respect to the covenants referred to therein shall exist after
giving effect to such sale, encumbrance, refinance or transfer.
Notwithstanding the foregoing, in the event of any sale, encumbrance, refinance
or transfer by the Borrower or its Subsidiaries or Investment Partnerships of
any Real Estate or any other Investment described in Section 8.3(i) involving
an amount in excess of $35,000,000.00, the Borrower shall promptly give notice

and those of its Subsidiaries and Investment Partnerships used or useful in the
conduct of its business or the business of its Subsidiaries and Investment
Partnerships to be maintained and kept in good condition, repair and working
order (ordinary wear and tear excepted) and supplied with all necessary
equipment, and (ii) will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof in all cases in which the
failure so to do would have a material adverse effect on the condition of its
properties or on the financial condition, assets or operations of the Borrower
and its Subsidiaries.

         Section 7.7.  Insurance.  The Borrower will procure and maintain or
cause to be procured and maintained insurance covering the Borrower and the
Guarantor and their respective Subsidiaries and Investment Partnerships and
their respective properties (the cost of such insurance to be borne by the

being given to the type of improvements thereon, their construction, location,
use and occupancy.

         Section 7.8.  Taxes.  The Borrower and each Subsidiary and Investment

well as all claims for labor, materials, or supplies that if unpaid might by
law become a lien or charge upon any of its property; provided that any such
tax, assessment, charge, levy or claim need not be paid if the validity or
amount thereof shall currently be contested in good faith by appropriate
proceedings and if the Borrower or such Subsidiary or Investment Partnership
shall have set aside on its books reasonably adequate reserves with respect
thereto; and provided, further, that forthwith upon the commencement of
proceedings to foreclose any lien that may have attached as security therefor,
the Borrower and each Subsidiary and Investment Partnership of the Borrower

provided, will pay each such tax, assessment, charge, levy or claim.

         Section 7.9.  Inspection of Properties and Books.  The Borrower shall
permit the Banks, through the Agent or any representative designated by the
Agent, to visit and inspect any of the properties of the Borrower or any of its
Subsidiaries or Investment Partnerships, to examine the books of account of the
Borrower and its Subsidiaries and Investment Partnerships (and to make copies
thereof and extracts therefrom) and to discuss the affairs, finances and
accounts of the Borrower and its Subsidiaries and Investment Partnerships with,
and to be advised as to the same by, its officers, all at such reasonable times
and intervals as the Agent or any Bank may reasonably request.  The Agent shall
use good faith efforts to coordinate such visits and inspections so as to
minimize the interference with and disruption to the Borrower's normal business
operations.  From and after the occurrence of an Event of Default which is
continuing, the Borrower shall bear the costs and expenses incurred by Agent or
its representatives in conducting such visits or inspections.

         Section 7.10.  Compliance with Laws, Contracts, Licenses, and Permits.
The Borrower will comply with, and will cause each of its Subsidiaries and
Investment Partnerships to comply in all respects with (i) all applicable laws
and regulations now or hereafter in effect wherever its business is conducted,
including all Environmental Laws, (ii) the provisions of its corporate charter,
partnership agreement or declaration of trust, as the case may be, and other
charter documents and bylaws, (iii) the Prospectus, (iv) all agreements and
instruments (other than the Loan Documents) to which it is a party or by which
it or any of its properties may be bound, (v) all applicable decrees, orders,
and judgments, and (vi) all licenses and permits required by applicable laws
and regulations for the conduct of its business or the ownership, use or
operation of its properties, except when a failure to so comply with the
foregoing (i) - (vi) would not have a material adverse effect on the business,
assets or financial condition of the Borrower or such Subsidiary or Investment
Partnership.  If at any time while any Loan or Note is outstanding or the Banks
have any obligation to make Loans hereunder, any authorization, consent,
approval, permit or license from any officer, agency or instrumentality of any
government shall become necessary or required in order that the Borrower may
fulfill any of its obligations hereunder, the Borrower will immediately take or
cause to be taken all steps necessary to obtain such authorization, consent,
approval, permit or license.

         Section 7.11.  Further Assurances.  The Borrower will cooperate with,
and will cause each of its Subsidiaries to cooperate with the Agent and the
Banks and execute such further instruments and documents as the Banks or the
Agent shall reasonably request to carry out to their satisfaction the
transactions contemplated by this Agreement and the other Loan Documents.

         Section 7.12.  Ownership of Real Estate.  All interests (whether
direct or indirect) of the Borrower, the General Partner, the Guarantor or
their respective Subsidiaries or the Borrower's Investment Partnerships in
income- producing real estate assets acquired after the date hereof shall be
owned directly by the Borrower or, subject to the terms of Section 8.3(m),
Investment Partnerships (other than interests in residential real estate
developments held by the Residential Corporations and other than as
specifically permitted in Section 8.14).

         Section 7.13.  Investment Advisor.  The Borrower shall be
self-directed and the Borrower shall not retain or otherwise rely on any other
Person for investment advisory services.

         Section 7.14.  Non-Competition Agreements.  The Non-Competition
Agreements have been duly executed and delivered, are in full force and effect,
and are the legal, valid and binding obligations of the parties thereto,
enforceable in accordance with their terms.  Without the prior written consent
of the Agent, the Borrower shall not (a) amend or modify any of the
Non-Competition Agreements, (b) terminate or surrender any of the
Non-Competition Agreements, or (c) waive or release any other party thereto
from the performance or observation by such Person of any obligation or
condition of any of the Non-Competition Agreements (provided that the foregoing
shall not prohibit Richard E. Rainwater, Gerald W. Haddock or John C. Goff from
obtaining waivers to specific transactions from a majority of the independent
directors of Crescent Guarantor as provided therein).  The Borrower shall, at
no cost or expense to the Agent, enforce, short of termination, the performance
and observance of each and every term, condition and covenant of each of the
Non-Competition Agreements to be performed or observed by the other parties
thereunder, and appear in and defend any action arising out of, or in any
manner connected with, any of the Non-Competition Agreements, and give prompt
notice to the Agent of any claim of default under any of the Non-Competition
Agreements, whether given by the Borrower to the other party thereto, or given
by the other party thereto to the Borrower.

         Section 7.15.  Business Operations. The Borrower shall operate its
business substantially as described in the Prospectus and in compliance with
the terms and conditions of this Agreement and the Loan Documents.

         Section 7.16.  Intentionally Omitted.

         Section 7.17.  Limiting Agreements.

                 (a)      Neither Borrower, the Guarantor, nor any of their
respective Subsidiaries or Investment Partnerships shall enter into any
agreement, instrument or transaction which has or may have the effect of
prohibiting or limiting Borrower's ability to pledge to Agent Real Estate which
is owned by the Borrower and is free and clear of all Liens other than the
Liens permitted in Section 8.2(i), (iii) and (vi) or any other assets of the
Borrower as security for the Loans.  Borrower shall take, and shall cause
Guarantor and their respective Subsidiaries and Investment Partnerships to
take, such actions as are necessary to preserve the right and ability of
Borrower to pledge those Real Estate and other assets as security for the Loans
without any such pledge after the date hereof causing or permitting the
acceleration (after the giving of notice or the passage of time, or otherwise)
of any other Indebtedness of Borrower, Guarantor, or any of their respective
Subsidiaries or Investment Partnerships.

                 (b)      Borrower shall, upon demand, provide to the Agent
such evidence as the Agent may reasonably require to evidence compliance with
this Section 7.17, which evidence shall include, without limitation, copies of
any agreements or instruments which would in any way restrict or limit the
Borrower's ability to pledge assets as security for Indebtedness, or which





                                      -44-
<PAGE>   51
provide for the occurrence of a default (after the giving of notice or the
passage of time, or otherwise) if assets are pledged in the future as security
for Indebtedness of the Borrower or any of its Subsidiaries.

         Section 7.18.  More Restrictive Agreements.  Should the Borrower or
the Guarantor enter into or modify any agreements or documents pertaining to
any existing or future Indebtedness, Debt Offering or Equity Offering, which
agreements or documents include covenants, whether affirmative or negative (or
any other provision which may have the same practical effect as any of the
foregoing), which are individually or in the aggregate more restrictive against
the Borrower, the Guarantor or their respective Subsidiaries than those set
forth in Articles 8 or 9 of this Agreement or Paragraph 11 of the Guaranty, the
Borrower shall promptly notify the Agent and, if requested by the Majority
Banks, the Borrower, the Agent, and the Majority Banks shall promptly amend
this Agreement and the other Loan Documents to include some or all of such more
restrictive provisions as determined by the Majority Banks in their sole
discretion.

         Section 7.19.  Applicability of Covenants to Residential Corporations
and Investment Partnerships.  By acceptance of this Agreement, the Banks agree
that the Borrower's obligations to cause the Residential Corporations and
Investment Partnerships to comply with the covenants set forth in Articles 7
and 8 of this Agreement shall be limited to the full extent that the Borrower
has the legal right, whether by contract, at law or in equity, to cause
compliance by the Residential Corporations with such covenants.

         Section 7.20.  Distributions of Income to the Borrower.  The Borrower
shall cause all of its Subsidiaries and Investment Partnerships to promptly
distribute to the Borrower (but not less frequently than once each fiscal
quarter of the Borrower), whether in the form of dividends, distributions or
otherwise, all profits, proceeds or other income relating to or arising from
its Subsidiaries' or Investment Partnerships' use, operation, financing,
refinancing, sale or other disposition of their respective assets and
properties after (a) the payment by each Subsidiary or Investment Partnership
of its Debt Service and operating expenses for such quarter and (b) the
establishment of reasonable reserves for the payment of operating expenses not
paid on at least a quarterly basis and capital improvements to be made to such
Subsidiary's or Investment Partnership's assets and properties approved by such
Subsidiary or Investment Partnership in the ordinary course of business
consistent with its past practices.  Notwithstanding the foregoing, the
Borrower shall enforce its rights at law and in equity to receive distributions
from (i) the Residential Corporations at the same time that distributions are
made to other shareholders of the Residential Corporations, and (ii)
Subsidiaries and Investment Partnerships of the Borrower in which the Borrower
owns less than a majority (by number of votes or controlling interests) of the
outstanding Voting Interests.

         SECTION 8.  CERTAIN NEGATIVE COVENANTS OF THE BORROWER.

         The Borrower covenants and agrees that, so long as any Loan or Note is

(including, without limitation, the conducting of engineering tests at the sole
expense of the Borrower) to confirm that no Hazardous Substances are or ever
were Released or disposed of on the Real Estate; and

                 (ii)     if any Release or disposal of Hazardous Substances
shall occur or shall have occurred on the Real Estate (including without
limitation any such Release or disposal occurring prior to the acquisition of
such Real Estate by the Borrower or its Subsidiary or Investment Partnership),
cause the prompt containment and removal of such Hazardous Substances and
remediation of the Real Estate in full compliance with all applicable laws and
regulations and to the reasonable satisfaction of the Majority Banks; provided,
that the Borrower shall be deemed to be in compliance with Environmental Laws
for the purpose of this clause (ii) so long as it or a responsible third party
with sufficient financial resources is taking reasonable action to remediate or
manage any event of noncompliance to the reasonable satisfaction of the
Majority Banks and no action shall have been commenced by any enforcement
agency.  The Majority Banks may engage their own environmental engineer to
review the environmental assessments and the Borrower's compliance with the
covenants contained herein.

         At any time after an Event of Default shall have occurred hereunder,
or, whether or not an Event of Default shall have occurred, at any time that
the Agent or the Majority Banks shall have reasonable grounds to believe that a
Release or threatened Release of Hazardous Substances may have occurred,
relating to any Real Estate, or that any of the Real Estate is not in
compliance with the Environmental Laws, the Agent may at its election (and will
at the request of the Majority Banks) obtain such environmental assessments of
such Real Estate prepared by an environmental engineer as may be necessary or
advisable for the purpose of evaluating or confirming (i) whether any Hazardous
Substances are present in the soil or water at or adjacent to such Real Estate
and (ii) whether the use and operation of such Real Estate comply with all
Environmental Laws.  Environmental assessments may include detailed visual
inspections of such Real Estate including, without limitation, any and all
storage areas, storage tanks, drains, dry wells and leaching areas, and the
taking of soil samples, as well as such other investigations or analyses as are
necessary or appropriate for a complete determination of the compliance of such
Real Estate and the use and operation thereof with all applicable Environmental
Laws.  All such environmental assessments shall be at the sole cost and expense
of the Borrower.

excess of (i) ninety percent (90%) of its Funds from Operations for such fiscal
quarters, or (ii) one hundred percent (100%) of its Funds Available for
Distribution for such fiscal quarters; provided that the limitation contained
in this Section 8.7(a) shall not preclude the Borrower from making
Distributions to Crescent Guarantor in an amount equal to the minimum

accounting officer of the General Partner containing calculations in detail
reasonably satisfactory in form and substance to the Agent.

                 (b)      In the event that a Default under Section 12.1(a) or

shall make no Distributions other than Distributions to Crescent Guarantor in
an amount equal to the minimum distributions required under the Code to
maintain the REIT Status of Crescent Guarantor, as evidenced by a certification
of the principal financial or accounting officer of the General Partner
containing calculations in detail reasonably satisfactory in form and substance

         Section 8.9.  Development Activity.  Without the consent of the
Majority Banks, neither the Borrower nor any Subsidiary or Investment

estate (provided that the foregoing shall not be deemed to be breached by the
residential real estate development activities by the Residential Corporations
nor the development activities permitted by the partnership agreements for the
Woodlands and Americold URS nor the restoration or rehabilitation of commercial
real estate following damage by casualty or condemnation).  The Borrower
acknowledges that the decision of the Majority Banks to grant or withhold such
consent shall be based on such factors as the Majority Banks deem relevant in
their sole discretion, including without limitation, evidence of sufficient
funds both from borrowings (other than from the Loans) and equity to complete
such development and evidence that the Borrower or its Subsidiary or Investment
Partnership has the resources and expertise necessary to complete such project.
Without limiting the foregoing, the Borrower acknowledges that for the purposes

property which is proposed to be developed or which is under development and
lease-up at the time such agreement is entered into, shall be considered a

demolition and reconstruction of the Surtran Garage at Continental Plaza,
provided that the cost of such renovation or demolition and reconstruction
shall not exceed $20,000,000.00, (iii) the construction of the Frost Bank

Borrower or any Subsidiary or Investment Partnership from acquiring Real Estate
which has been developed and initially leased by another Person.

         Section 8.10.  Investment Opportunities.  During the term of the
Non-Competition Agreements, the Borrower shall cause each of Richard E.
Rainwater, Gerald W. Haddock and John C. Goff to offer to the Borrower all real
estate investment opportunities that are presented to any of such individuals,
and if the Borrower elects not to participate in such opportunity, the Borrower
shall not permit any of such individuals, or any Person controlling, controlled
by or under common control with any of such individuals, to participate in such
investment, unless such transaction is approved by a majority of the

scheduled maturity date which is earlier than the maturity date with respect to
the portion of the Existing Fixed Rate Indebtedness that is being refinanced or

(such as a REMIC), as determined by the Agent in its reasonable discretion,
other than in connection with the acquisition of the Behavioral Healthcare
Facilities (provided that its debt shall not exceed $350,000,000.00).

period.

portion of the period for which data is needed to test compliance with this

payment;

                 (b)      the Borrower shall fail to pay any interest on the

provided, however, that no Event of Default shall exist hereunder upon the
breach of either of the covenants described in Section 9.12(iii) or (iv) in the
event that the Borrower cures such default within one hundred eighty (180) days
following receipt of written notice of such default;

this Agreement, any advance of a Loan or any of the other Loan Documents shall
prove to have been false in any material respect upon the date when made or
deemed to have been made or repeated;

                 (g)      the Borrower, any of its general partners, the
Guarantor or any of the Borrower's Subsidiaries shall fail to pay at maturity,
or within any applicable period of grace, any obligation for borrowed money or
credit received, or fail to observe or perform any material term,

covenant or agreement contained in any agreement by which it is bound,

period of time as would permit (assuming the giving of appropriate notice if
required) the holder or holders thereof or of any obligations issued thereunder
to accelerate the maturity thereof;

                 (h)      the Borrower, any of its general partners, the

or generally fail to pay its debts as they mature or become due, or shall

the assets of any thereof, (2) shall commence any case or other proceeding
relating to the Borrower, any of its general partners, the Guarantor or any of
the Borrower's Subsidiaries under any bankruptcy, reorganization, arrangement,
insolvency, readjustment of debt, dissolution or liquidation or similar law of
any jurisdiction, now or hereafter in effect, or (3) shall take any action to
authorize or in furtherance of any of the foregoing;

                 (i)      a petition or application shall be filed for the
appointment of a trustee or other custodian, liquidator or receiver of the
Borrower, any of its general partners, the Guarantor  or any of the Borrower's
Subsidiaries or any substantial part of the assets of any thereof, or a case or
other proceeding shall be commenced against the Borrower, any of its general
partners, the Guarantor or any of the Borrower's Subsidiaries under any
bankruptcy, reorganization, arrangement, insolvency, readjustment of debt,
dissolution or liquidation or similar law of any jurisdiction, now or hereafter

proceeding shall not have been dismissed within 90 days following the filing or

                 (j)      a decree or order is entered appointing any such

<PAGE>   68
proceeding to cancel, revoke or rescind any of the Loan Documents shall be
commenced by or on behalf of the Borrower, any of its general partners, the
Guarantor, any of the Borrower's Subsidiaries or Investment Partnerships or any
of their respective stockholders, partners or beneficiaries, or any court or
any other governmental or regulatory authority or agency of competent
jurisdiction shall make a determination that, or issue a judgment, order,
decree or ruling to the effect that, any one or more of the Loan Documents is

                 (m)      any dissolution, termination, partial or complete
liquidation, merger or consolidation of the Borrower, any of its general
partners or the Guarantor, or any sale, transfer or other disposition of the
assets of the Borrower, any of its general partners or the Guarantor, other
than as permitted under the terms of this Agreement or the other Loan
Documents;

                 (n)      any suit or proceeding shall be filed against the
Borrower, the Guarantor or any of their respective assets, which in the good
faith business judgment of the Majority Banks after giving consideration to the
likelihood of success of such suit or proceeding and the availability of
insurance to cover any judgment with respect thereto and based on the
information available to them, if adversely determined, would have a materially
adverse affect on the ability of the Borrower or the Guarantor to perform each
and every one of its respective obligations under and by virtue of the Loan
Documents;

                 (o)      the Borrower, any of its general partners, the

forfeiture of any assets of such Person;

                 (p)      with respect to any Guaranteed Pension Plan, an ERISA
Reportable Event shall have occurred and the Majority Banks shall have
determined in their reasonable discretion that such event reasonably could be
expected to result in liability of the Borrower, any of its general partners,
the Guarantor or any of the Borrower's Subsidiaries to the PBGC or such
Guaranteed Pension Plan in an aggregate amount exceeding $1,000,000 and such
event in the circumstances occurring reasonably could constitute grounds for
the termination of such Guaranteed Pension Plan by the PBGC or for the
appointment by the appropriate United States District Court of a trustee to
administer such Guaranteed Pension Plan; or a trustee shall have been appointed
by the United States District Court to administer such Plan; or the PBGC shall
have instituted proceedings to terminate such Guaranteed Pension Plan;

                 (q)      the Guarantor denies that it has any liability or
obligation under the Guaranty, or shall notify the Agent or any of the Banks of
the Guarantor's intention to attempt to cancel or terminate the Guaranty, or
shall fail to observe or comply with any term, covenant, condition or agreement
under the Guaranty;

                 (r)      (1) at least two of Richard Rainwater, John C. Goff
and Gerald Haddock shall not collectively occupy two of the following
positions: Chairman of the Board, Chief Executive Officer, Vice-Chairman and
President of Crescent Guarantor, or (2) Richard





                                      -62-
<PAGE>   69
Rainwater, John C. Goff and Gerald Haddock in the aggregate shall no longer own
units in the Borrower or shares in Crescent Guarantor which, on a combined
basis, equal to at least a ten percent (10%) economic interest in the Borrower
(provided, however, in the event that the circumstances described in (1) or (2)
have occurred as a result of the death or mental incapacity of any of such
Persons, the same shall not constitute an Event of Default hereunder so long as
within six (6) months from the date of such death or mental incapacitation the
Majority Banks shall have approved the individual or individuals who shall
replace such Person as the Chairman of the Board, Chief Executive Officer,
Vice- Chairman or President, as applicable, of Crescent Guarantor and who shall
own such interests in the Borrower and Crescent Guarantor), or (3) without the
prior written approval of the Majority Banks there shall be any other material
change in the management of Crescent Guarantor or the Borrower; or

                 (s)      any default or Event of Default, as defined in any of
the other Loan Documents, shall occur;

then, and in any such event, the Agent may, and upon the request of the
Majority Banks shall, by notice in writing to the Borrower declare all amounts
owing with respect to this Agreement, the Notes and the other Loan Documents to
be, and they shall thereupon forthwith become, immediately due and payable
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by the Borrower; provided that in the event of any
Event of Default specified in Section 12.1(h), Section 12.1(i) or Section
12.1(j), all such amounts shall become immediately due and payable
automatically and without any requirement of notice from any of the Banks or
the Agent.

         Section 12.2.  Limitation of Cure Periods.

                 (a)      Notwithstanding anything contained in Section 12.1 to
the contrary, (i) no Event of Default shall exist hereunder upon the occurrence
of any failure described in Section 12.1(a) or Section 12.1(b) in the event
that the Borrower cures such default within five (5) days following receipt of
written notice of such default, provided, however, that Borrower shall not be
entitled to receive more than two (2) notices in the aggregate pursuant to this
clause (i) in any period of 365 days ending on the date of any such occurrence
of default, and provided further that no such cure period shall apply to any
payments due upon the maturity of the Notes, and (ii) no Event of Default shall
exist hereunder upon the occurrence of any failure described in Section 12.1(e)
in the event that the Borrower cures such default with thirty (30) days
following receipt of written notice of such default, provided that the
provisions of this clause shall not pertain to defaults consisting of a failure
to comply with Section 7.4(d) or to any default excluded from any provision of
cure of defaults contained in any other of the Loan Documents.

                 (b)      Notwithstanding the provisions of Section 12.1(d),
the cure period provided therein shall not be allowed and the occurrence of a
Default thereunder immediately shall constitute an Event of Default for all
purposes of this Agreement and the other Loan Documents if, within the period
of twelve months immediately preceding the occurrence of such Default, there
shall have occurred two periods of cure or portions thereof under said
subsection.

<PAGE>   70
         Section 12.3.  Termination of Commitments.  If any one or more Events
of Default specified in Section 12.1(h), Section 12.1(i) or Section 12.1(j)
shall occur, then immediately and without any action on the part of the Agent
or any Bank any unused portion of the credit hereunder shall terminate and the
Banks shall be relieved of all obligations to make Loans to the Borrower.  If
any other Event of Default shall have occurred, the Agent, upon the election of
the Majority Banks, may by notice to the Borrower terminate the obligation to
make Loans to the Borrower.  No termination under this Section 12.3 shall
relieve the Borrower of its obligations to the Banks arising under this
Agreement or the other Loan Documents.  Nothing in this Section 12.3 shall
limit or impair the terms of this Agreement (including Section 2.1) which
provide that the Banks shall have no obligation to make Loans upon the
occurrence of a Default or Event of Default.

         Section 12.4.  Remedies. In case any one or more of the Events of
Default shall have occurred and be continuing, and whether or not the Banks
shall have accelerated the maturity of the Loans pursuant to Section 12.1, the
Agent on behalf of the Banks, may, with the consent of the Majority Banks but
not otherwise, proceed to protect and enforce their rights and remedies under
this Agreement, the Notes or any of the other Loan Documents by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement and the
other Loan Documents or any instrument pursuant to which the Obligations are
evidenced, including to the full extent permitted by applicable law the
obtaining of the ex parte appointment of a receiver, and, if such amount shall
have become due, by declaration or otherwise, proceed to enforce the payment
thereof or any other legal or equitable right.  No remedy herein conferred upon
the Agent or the holder of any Note is intended to be exclusive of any other
remedy and each and every remedy shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or any other provision of law.  In the event that all or
any portion of the Obligations is collected by or through an attorney-at-law,
the Borrower shall pay all reasonable costs of collection including, but not
limited to, reasonable attorney's fees.

         Section 12.5.  Distribution of Proceeds.  In the event that, following
the occurrence or during the continuance of any Event of Default, any monies
are received in connection with the enforcement of any of the Loan Documents,
or otherwise with respect to the realization upon any of the assets of the
Borrower or the Guarantor, such monies shall be distributed for application as
follows:

                 (a)      First, to the payment of, or (as the case may be) the
reimbursement of, the Agent for or in respect of all reasonable costs,
expenses, disbursements and losses which shall have been incurred or sustained
by the Agent to protect or preserve any collateral or in connection with the
collection of such monies by the Agent, for the exercise, protection or
enforcement by the Agent of all or any of the rights, remedies, powers and
privileges of the Agent under this Agreement or any of the other Loan Documents
or in support of any provision of adequate indemnity to the Agent against any
taxes or liens which by law shall have, or may have, priority over the rights
of the Agent to such monies;





                                      -64-
<PAGE>   71
                 (b)      Second, to all other Obligations in such order or
preference as the Majority Banks shall determine; provided, however, that (i)
distributions in respect of such other Obligations shall be made pari passu
among Obligations with respect to the Agent's fee payable pursuant to Section
4.3 and all other Obligations, (ii) in the event that any Bank shall have
wrongfully failed or refused to make an advance under Section 2.7 and such
failure or refusal shall be continuing, advances made by other Banks during the
pendency of such failure or refusal shall be entitled to be repaid as to
principal and accrued interest in priority to the other Obligations described
in this subsection (b), and (iii) Obligations owing to the Banks with respect
to each type of Obligation such as interest, principal, fees and expenses,
shall be made among the Banks pro rata; and provided further that the Majority
Banks may in their discretion make proper allowance to take into account any
Obligations not then due and payable; and

                 (c)      Third, the excess, if any, shall be returned to the
Borrower or to such other Persons as are entitled thereto.

         SECTION 13.  SETOFF.

     Regardless of the adequacy of any collateral, during the continuance of
any Event of Default, any deposits (general or specific, time or demand,
provisional or final, regardless of currency, maturity, or the branch of where
such deposits are held) or other sums credited by or due from any of the Banks
to the Borrower or the Guarantor and any securities or other property of the
Borrower or the Guarantor in the possession of such Bank may be applied to or
set off against the payment of Obligations and any and all other liabilities,
direct, or indirect, absolute or contingent, due or to become due, now existing
or hereafter arising, of the Borrower to such Bank.  Each of the Banks agrees
with each other Bank that if such Bank shall receive from the Borrower or the
Guarantor, whether by voluntary payment, exercise of the right of setoff, or
otherwise, and shall retain and apply to the payment of the Note or Notes held
by such Bank any amount in excess of its ratable portion of the payments
received by all of the Banks with respect to the Notes held by all of the
Banks, such Bank will make such disposition and arrangements with the other
Banks with respect to such excess, either by way of distribution, pro tanto
assignment of claims, subrogation or otherwise as shall result in each Bank
receiving in respect of the Notes held by it its proportionate payment as
contemplated by this Agreement; provided that if all or any part of such excess
payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.

         SECTION 14.  THE AGENT.

         Section 14.1.  Authorization.  The Agent is authorized to take such
action on behalf of each of the Banks and to exercise all such powers as are
hereunder and under any of the other Loan Documents and any related documents
delegated to the Agent, together with such powers as are reasonably incident
thereto, provided that no duties or responsibilities not expressly assumed
herein or therein shall be implied to have been assumed by the Agent.  The
obligations of Agent hereunder are primarily administrative in nature, and
nothing contained in this Agreement, or any of the other Loan Documents shall
be construed to constitute the Agent as a trustee for any Bank





                                      -65-
<PAGE>   72
or to create an agency or fiduciary relationship.  The Borrower and any other
Person shall be entitled to conclusively rely on a statement from the Agent
that it has the authority to act for and bind the Banks pursuant to this
Agreement and the other Loan Documents.

         Section 14.2.  Employees and Agents.  The Agent may exercise its
powers and execute its duties by or through employees or agents and shall be
entitled to take, and to rely on, advice of counsel concerning all matters
pertaining to its rights and duties under this Agreement and the other Loan
Documents. The Agent may utilize the services of such Persons as the Agent may
reasonably determine, and all reasonable fees and expenses of any such Persons
shall be paid by the Borrower.

         Section 14.3.  No Liability.  Neither the Agent nor any of its
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent, or employee thereof, shall be liable for
any waiver, consent or approval given or any action taken, or omitted to be
taken, in good faith by it or them hereunder or under any of the other Loan
Documents, or in connection herewith or therewith, or be responsible for the
consequences of any oversight or error of judgment whatsoever, except that the
Agent or such other Person, as the case may be, shall be liable for losses due
to its willful misconduct or gross negligence.

         Section 14.4.  No Representations.  The Agent shall not be responsible
for the execution or validity or enforceability of this Agreement, the Notes,
any of the other Loan Documents or any instrument at any time constituting, or
intended to constitute, collateral security for the Notes, or for the value of
any such collateral security or for the validity, enforceability or
collectability of any such amounts owing with respect to the Notes, or for any
recitals or statements, warranties or representations made herein, or any
agreement, instrument or certificate delivered in connection therewith or in
any of the other Loan Documents or in any certificate or instrument hereafter
furnished to it by or on behalf of the Borrower or any of its Subsidiaries or
Investment Partnerships or the Guarantor, or be bound to ascertain or inquire
as to the performance or observance of any of the terms, conditions, covenants
or agreements herein or in any other of the Loan Documents.  The Agent shall
not be bound to ascertain whether any notice, consent, waiver or request
delivered to it by the Borrower or the Guarantor or any of their respective
Subsidiaries or Investment Partnerships or any holder of any of the Notes shall
have been duly authorized or is true, accurate and complete.  The Agent has not
made nor does it now make any representations or warranties, express or
implied, nor does it assume any liability to the Banks, with respect to the
creditworthiness or financial condition of the Borrower or any of its
Subsidiaries or Investment Partnerships or the Guarantor.  Each Bank
acknowledges that it has, independently and without reliance upon the Agent or
any other Bank, and based upon such information and documents as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.  Each Bank also acknowledges that it will, independently and without
reliance upon the Agent or any other Bank, based upon such information and
documents as it deems appropriate at the time, continue to make its own credit
analysis and decisions in taking or not taking action under this Agreement and
the other Loan Documents.

<PAGE>   73
         Section 14.5.  Payments.

                 (a)      A payment by the Borrower or the Guarantor to the
Agent hereunder or under any of the other Loan Documents for the account of any
Bank shall constitute a payment to such Bank.  The Agent agrees to distribute
to each Bank not later than one Business Day after the Agent's receipt of good
funds, determined in accordance with the Agent's customary practices, such
Bank's pro rata share of payments received by the Agent for the account of the
Banks except as otherwise expressly provided herein or in any of the other Loan
Documents.  In the event that the Agent fails to distribute such amounts within
one Business Day as provided above, the Agent shall pay interest on such amount
at a rate per annum equal to the Federal Funds Effective Rate from time to time
in effect.

                 (b)      If in the opinion of the Agent the distribution of
any amount received by it in such capacity hereunder, under the Notes or under
any of the other Loan Documents might involve it in liability, it may refrain
from making distribution until its right to make distribution shall have been
adjudicated by a court of competent jurisdiction.  If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the
Agent is to be repaid, each Person to whom any such distribution shall have
been made shall either repay to the Agent its proportionate share of the amount
so adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such court.

                 (c)      Notwithstanding anything to the contrary contained in
this Agreement or any of the other Loan Documents, any Bank that fails (i) to
make available to the Agent its pro rata share of any Loan or (ii) to comply
with the provisions of Section 13 with respect to making dispositions and
arrangements with the other Banks, where such Bank's share of any payment
received, whether by setoff or otherwise, is in excess of its pro rata share of
such payments due and payable to all of the Banks, in each case as, when and to
the full extent required by the provisions of this Agreement, shall be deemed
delinquent (a "Delinquent Bank") and shall be deemed a Delinquent Bank until
such time as such delinquency is satisfied.  A Delinquent Bank shall be deemed
to have assigned any and all payments due to it from the Borrower and the
Guarantor, whether on account of outstanding Loans, interest, fees or
otherwise, to the remaining nondelinquent Banks for application to, and
reduction of, their respective pro rata shares of all outstanding Loans.  The
Delinquent Bank hereby authorizes the Agent to distribute such payments to the
nondelinquent Banks in proportion to their respective pro rata shares of all
outstanding Loans.  A Delinquent Bank shall be deemed to have satisfied in full
a delinquency when and if, as a result of application of the assigned payments
to all outstanding Loans of the nondelinquent Banks or as a result of other
payments by the Delinquent Banks to the nondelinquent Banks, the Banks'
respective pro rata shares of all outstanding Loans have returned to those in
effect immediately prior to such delinquency and without giving effect to the
nonpayment causing such delinquency.

<PAGE>   74
         Section 14.6.  Holders of Notes.  Subject to the terms of Article 18,
the Agent may deem and treat the payee of any Note as the absolute owner or
purchaser thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder, assignee
or transferee.

         Section 14.7.  Indemnity.  The Banks ratably agree hereby to indemnify
and hold harmless the Agent from and against any and all claims, actions and
suits (whether groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Agent has not been reimbursed by the
Borrower as required by Section 15), and liabilities of every nature and
character arising out of or related to this Agreement, the Notes or any of the
other Loan Documents or the transactions contemplated or evidenced hereby or
thereby, or the Agent's actions taken hereunder or thereunder, except to the
extent that any of the same shall be directly caused by the Agent's willful
misconduct or gross negligence.

         Section 14.8.  Agent as Bank.  In its individual capacity, BankBoston
shall have the same obligations and the same rights, powers and privileges in
respect to its Commitment and the Loans made by it, and as the holder of any of
the Notes as it would have were it not also the Agent.

         Section 14.9.  Resignation.  Subject to the terms of Section 18.1, the
Agent may resign at any time by giving 30 calendar days' prior written notice
thereof to the Banks and the Borrower.  Upon any such resignation, the Majority
Banks, subject to the terms of Section 18.1, shall have the right to appoint as
a successor Agent any Bank or any bank whose senior debt obligations are rated
not less than "A" or its equivalent by Moody's Investors Service, Inc. or not
less than "A" or its equivalent by Standard & Poor's corporation and which has
a net worth of not less than $500,000,000.  Unless a Default or Event of
Default shall have occurred and be continuing, such successor Agent shall be
reasonably acceptable to the Borrower.  If no successor Agent shall have been
appointed and shall have accepted such appointment within thirty (30) days
after the retiring Agent's giving of notice of resignation, then the retiring
Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a
bank whose debt obligations are rated not less than "A" or its equivalent by
Moody's Investors Service, Inc. or not less than "A" or its equivalent by
Standard & Poor's Corporation and which has a net worth of not less than
$500,000,000.  Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring or
removed Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder as Agent.  After any retiring Agent's resignation, the
provisions of this Agreement and the other Loan Documents shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken
by it while it was acting as Agent.  Upon any change in the Agent under this
Agreement, the resigning Agent shall execute such assignments of and amendments
to the Loan Documents as may be necessary to substitute the successor Agent for
the resigning Agent.

         Section 14.10.  Duties in the Case of Enforcement.  In case one or
more Events of Default have occurred and shall be continuing, and whether or
not acceleration of the Obligations shall have occurred, the Agent shall, if
(a) so requested by the Majority Banks and (b) the Banks have





                                      -68-
<PAGE>   75
provided to the Agent such additional indemnities and assurances against
expenses and liabilities as the Agent may reasonably request, proceed to
exercise all or any legal and equitable and other rights or remedies as it may
have.  The Majority Banks may direct the Agent in writing as to the method and
the extent of any such exercise, the Banks hereby agreeing to indemnify and
hold the Agent harmless from all liabilities incurred in respect of all actions
taken or omitted in accordance with such directions, provided that the Agent
need not comply with any such direction to the extent that the Agent reasonably
believes the Agent's compliance with such direction to be unlawful or
commercially unreasonable in any applicable jurisdiction.

         SECTION 18.  ASSIGNMENT AND PARTICIPATION.

         Section 18.1.  Conditions to Assignment by Banks.  Except as provided
herein, each Bank may assign to one or more banks or other entities all or a
portion of its interests, rights and obligations under this Agreement
(including all or a portion of its Commitment Percentage and Commitment and the
same portion of the Loans at the time owing to it, and the Notes held by it);
provided that (a) the Agent shall have given its prior written consent to such
assignment, which consent shall not be unreasonably withheld (provided that
such consent shall not be required for any assignment to another Bank or to a
wholly-owned subsidiary of such Bank provided that such assignee shall remain a
wholly-owned subsidiary of such Bank), (b) each such assignment shall be of a
constant, and not a varying, percentage of all the assigning Bank's rights and
obligations under this Agreement, (c) the parties to such assignment shall
execute and deliver to the Agent, for recording in the Register (as hereinafter
defined), a notice of such assignment, together with any Notes subject to such
assignment, (d) in no event shall any voting, consent or approval rights of a
Bank be assigned to any Person controlling, controlled by or under common
control with, or which is not otherwise free from influence or control by, the
Borrower, any of its general partners, the Guarantor or their respective
Subsidiaries or Investment Partnerships, which rights shall instead be
allocated pro rata among the other remaining Banks, (e) such assignee shall
have a net worth as of the date of such assignment of not less than
$500,000,000 unless such requirement is waived in writing by the Borrower and
the Agent, (f) such assignment is subject to the terms of any intercreditor
agreement among the Banks and the Agent, and (g) such assignee shall acquire an
interest in the Loans of not less than $10,000,000.00.  Upon such execution,
delivery, acceptance and recording, of such notice of assignment, (i) the
assignee thereunder shall be a party hereto and all other Loan Documents
executed by the Banks and, to the extent provided in such assignment, have the
rights and obligations of a Bank hereunder, (ii) the





                                      -71-
<PAGE>   78
assigning Bank shall, to the extent provided in such assignment and upon
payment to the Agent of the registration fee referred to in Section 18.2, be
released from its obligations under this Agreement, and (iii) the Agent may
unilaterally amend Schedule 1 to reflect such assignment.  In connection with
each assignment, the assignee shall represent and warrant to the Agent, the
assignor and each other Bank as to whether such assignee is controlling,
controlled by, under common control with or is not otherwise free from
influence or control by, the Borrower, its general partners, and the Guarantor
or their respective Subsidiaries or Investment Partnerships. Notwithstanding
anything herein to the contrary, in the event that BankBoston shall at any time
hold a Commitment equal to or less than $40,000,000.00 then BankBoston shall
first provide written notice thereof to the Banks and shall offer to resign as
Agent, which offer must be accepted in writing by the Majority Banks within
fifteen (15) days of delivery of such notice by Agent (for the purposes of this
sentence only BankBoston shall be deemed to have accepted its own offer to
resign).  A failure to accept such offer within such period shall be deemed a
rejection of such offer.  NationsBank shall have a period of fifteen (15)
calendar days following the acceptance by the Majority Banks of BankBoston's
offer to resign within which to elect to replace BankBoston as Agent (provided,
however, that the option of NationsBank to replace BankBoston as Agent shall be
null and void in the event that NationsBank has at such time, without regard to
any assignment to be made by BankBoston, a Commitment which is not greater than
or equal to the Commitment of each other Bank other than BankBoston or in the
event that within such thirty (30) calendar day period the Majority Banks do
not approve NationsBank so acting as Agent).  In the event that the Majority
Banks have accepted BankBoston's offer to resign and NationsBank declines to
replace BankBoston as Agent, is not eligible to replace BankBoston as Agent or
is not approved by the Majority Banks as the successor Agent as provided above,
BankBoston shall thereafter resign as Agent as provided in this Agreement in
the event that a successor Agent from among the Banks is not selected by the
Majority Banks or does not accept such appointment within fifteen (15) calendar
days following receipt of notice from Agent that NationsBank has declined to
replace BankBoston as Agent or a determination or vote that NationsBank is
ineligible or not approved.  Except with respect to the rights of NationsBank
as provided above to succeed BankBoston as Agent, each Agent, as a condition to
any resignation of its position as Agent shall be required to provide written
notice thereof to the other Banks and provide the Majority Banks an opportunity
to designate a successor Agent within thirty (30) calendar days following
receipt of such notice in the same manner as provided above.  Upon any change
in the Agent under this Agreement, the resigning or removed Agent shall execute
such assignments of and amendments to the Loan Documents as may be necessary to
substitute the successor Agent for the resigning or removed Agent.

         Section 18.2.  Register.  The Agent shall maintain a copy of each
assignment delivered to it and a register or similar list (the "Register") for
the recordation of the names and addresses of the Banks and the Commitment
Percentages of, and principal amount of the Loans owing to the Banks from time
to time.  The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, the Agent and the Banks may treat each Person
whose name is recorded in the Register as a Bank hereunder for all purposes of
this Agreement.  The Register shall be available for inspection by the Borrower
and the Banks at any reasonable time and from time to time upon





                                      -72-
<PAGE>   79
reasonable prior notice.  Upon each such recordation, the assigning Bank agrees
to pay to the Agent a registration fee in the sum of $5,000.

         Section 18.3.  New Notes.  Upon its receipt of an assignment executed
by the parties to such assignment, together with each Note subject to such
assignment, the Agent shall (a) record the information contained therein in the
Register, and (b) give prompt notice thereof to the Borrower and the Banks
(other than the assigning Bank).  Within five Business Days after receipt of
such notice, the Borrower, at its own expense, shall execute and deliver to the
Agent, in exchange for each surrendered Note, a new Note to the order of such
assignee in an amount equal to the amount assumed by such assignee pursuant to
such assignment and, if the assigning Bank has retained some portion of its
obligations hereunder, a new Note to the order of the assigning Bank in an
amount equal to the amount retained by it hereunder, and shall cause the
Guarantor to deliver to the Agent an acknowledgment in form and substance
reasonably satisfactory to the Agent to the effect that the Guaranty extends to
and is applicable to each new Note.  Such new Notes shall provide that they are
replacements for the surrendered Notes, shall be in an aggregate principal
amount equal to the aggregate principal amount of the surrendered Notes, shall
be dated the effective date of such assignment and shall otherwise be in
substantially the form of the assigned Notes.  The surrendered Notes shall be
canceled and returned to the Borrower.

         Section 18.4.  Participations.  Each Bank may sell participations to
one or more banks or other entities in all or a portion of such Bank's rights
and obligations under this Agreement and the other Loan Documents; provided
that (a) any such sale or participation shall not affect the rights and duties
of the selling Bank hereunder to the Borrower, (b) such participation shall not
entitle such participant to any rights or privileges under this Agreement or
the Loan Documents, including, without limitation, the right to approve
waivers, amendments or modifications, (c) such participant shall have no direct
rights against the Borrower, any of its general partners, the Guarantor or any
of their respective Subsidiaries or Investment Partnerships except the rights
granted to the Banks pursuant to Section 13, (d) such sale is effected in
accordance with all applicable laws, and (e) such participant shall not be a
Person controlling, controlled by or under common control with, or which is not
otherwise free from influence or control by, the Borrower, any of its general
partners, the Guarantor or any of their respective Subsidiaries or Investment
Partnerships.

         Section 18.5.  Pledge by Bank.  Any Bank may at any time pledge all or
any portion of its interest and rights under this Agreement (including all or
any portion of its Note) to any of the twelve Federal Reserve Banks organized
under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341.  No such
pledge or the enforcement thereof shall release the pledgor Bank from its
obligations hereunder or under any of the other Loan Documents.

         Section 18.6.  No Assignment by Borrower.  The Borrower shall not
assign or transfer any of its rights or obligations under any of the Loan
Documents without the prior written consent of each of the Banks.

<PAGE>   80
         Section 18.7.  Disclosure.  The Borrower agrees that in addition to
disclosures made in accordance with standard banking practices any Bank may
disclose information obtained by such Bank pursuant to this Agreement to
assignees or participants and potential assignees or participants hereunder.

         Section 18.8.  Restrictions on Assignment.  Notwithstanding anything
in this Agreement to the contrary, no Bank other than BankBoston shall be
permitted to assign all or any portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitment Percentage
and Commitment and the same portion of the Loans at the time owing to it, and
the Notes held by it) or the other Loan Documents prior to the date that is one
hundred eighty days (180) following the Closing Date without the prior written
consent of BankBoston, which consent maybe withheld by BankBoston in its sole
and absolute discretion.  Nothing herein shall prevent the sale by a Bank of a
participation pursuant to Section 18.4 of this Agreement during such period.

         SECTION 19.  NOTICES.

         Each notice, demand, election or request provided for or permitted to

time during the term of this Agreement to change their respective addresses and
each shall have the right to specify as its address any other address within

between each Bank and the Borrower is solely that of a lender and borrower, and
nothing contained herein or in any of the other Loan Documents shall in any

TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH THEY ARE
PARTIES BY, AMONG OTHER THINGS, THE WAIVERS AND CERTIFICATIONS CONTAINED IN
THIS SECTION 25.

         SECTION 26.  DEALINGS WITH THE BORROWER.

         The Banks and their affiliates may accept deposits from, extend credit

of this Agreement or such other instrument or the continuance of any Default or
Event of Default may be waived (either generally or in a particular instance
and either retroactively or prospectively) with, but only with, the written
consent of the Majority Banks.  Notwithstanding the foregoing, none of the
following may occur without the written consent of each Bank:  a change in the
rate of interest on and the term of the Notes; except as provided in Section

waiver of the principal of any unpaid Loan or any interest thereon; a change in
the amount of any fee payable to a Bank hereunder; an extension of Maturity

any payment of principal of or interest on the Loan; any change in the manner
of distribution of any payments to the Banks or Agent; a change to the
provisions of Section 2.1 which provide that the Banks shall not be required to

to waive a Default or Event of Default or agree to make an advance
notwithstanding such Default of Event of Default); or an amendment of the

this Agreement or the other Loan Documents as reasonably may be requested by
BankBoston in connection with the syndication by BankBoston of its Commitment,
provided that no such amendment or modification materially affects or increases
any of the obligations of the Borrower hereunder.  No waiver shall extend to or
affect any obligation not expressly waived or impair any right consequent
thereon.  No course of dealing or delay or omission on the part of the Agent or
any Bank in exercising any right shall operate as a waiver thereof or otherwise
be prejudicial thereto.  No notice to or demand upon the Borrower shall entitle
the Borrower to other or further notice or demand in similar or other
circumstances.

         FOR VALUE RECEIVED, the undersigned CRESCENT REAL ESTATE EQUITIES
LIMITED PARTNERSHIP, a Delaware limited partnership, hereby promises to pay to
_______________________________________ or order, in accordance with the terms
of that certain Fifth Amended and Restated Revolving Credit Agreement dated
June 30, 1998 (the "Credit Agreement"), as from time to time in effect, among
the undersigned, BankBoston, N.A., for itself and as Agent, and such other
Banks as may be from time to time named therein, to the extent not sooner paid,
on or before the Maturity Date, the principal sum of __________________________
DOLLARS ($______________), or such amount as may be advanced by the payee
hereof under the Credit Agreement with daily interest from the date hereof,
computed as provided in the Credit Agreement, on the principal amount hereof
from time to time unpaid, at a rate per annum on each portion of the principal
amount which shall at all times be equal to the rate of interest applicable to
such portion in accordance with the Credit Agreement, and with interest on
overdue principal and, to the extent permitted by applicable law, on overdue
installments of interest and late charges at the rates provided in the Credit
Agreement.  Interest shall be payable on the dates specified in the Credit
Agreement, except that all accrued interest shall be paid at the stated or
accelerated maturity hereof or upon the prepayment in full hereof.  Capitalized
terms used herein and not otherwise defined herein shall have the meanings set
forth in the Credit Agreement.

         Payments hereunder shall be made to BankBoston, N.A., as Agent for the
payee hereof, 100 Federal Street, Boston, Massachusetts 02110.

         This Note is one of one or more Notes evidencing borrowings under and
is entitled to the benefits and subject to the provisions of the Credit
Agreement.  The principal of this Note may be due and payable in whole or in
part prior to the maturity date stated above and is subject to mandatory
prepayment in the amounts and under the circumstances set forth in the Credit
Agreement, and may be prepaid in whole or from time to time in part, all as set
forth in the Credit Agreement.

         Notwithstanding anything in this Note to the contrary, all agreements
between the Borrower and the Banks and the Agent, whether now existing or
hereafter arising and whether written or oral, are hereby limited so that in no
contingency, whether by reason of acceleration of the maturity of any of the
Obligations or otherwise, shall the interest contracted for, charged or
received by the Banks exceed the maximum amount permissible under applicable
law.  If, from any circumstance whatsoever, interest would otherwise be payable
to the Banks in excess of the maximum lawful amount, the interest payable to
the Banks shall be reduced to the maximum amount permitted under applicable
law; and if from any circumstance the Banks shall ever receive
<PAGE>   102
anything of value deemed interest by applicable law in excess of the maximum
lawful amount, an amount equal to any excessive interest shall be applied to
the reduction of the principal balance of the Obligations and to the payment of
interest or, if such excessive interest exceeds the unpaid balance of principal
of the Obligations, such excess shall be refunded to the Borrower.  All
interest paid or agreed to be paid to the Banks shall, to the extent permitted
by applicable law, be amortized, prorated, allocated and spread throughout the
full period until payment in full of the principal of the Obligations
(including the period of any renewal or extension thereof) so that the interest
thereon for such full period shall not exceed the maximum amount permitted by
applicable law.  This paragraph shall control all agreements between the
Borrower and the Banks and the Agent.

         In case an Event of Default shall occur, the entire principal amount
of this Note may become or be declared due and payable in the manner and with
the effect provided in said Credit Agreement.

         This Note shall be governed by and construed in accordance with the
laws of the Commonwealth of Massachusetts (without giving effect to the
conflict of laws rules of any jurisdiction).

         The undersigned maker and all guarantors and endorsers, hereby waive
presentment, demand, notice, protest, notice of intention to accelerate the
indebtedness evidenced hereby, notice of acceleration of the indebtedness
evidenced hereby and all other demands and notices in connection with the
delivery, acceptance, performance and enforcement of this Note, except as
specifically otherwise provided in the Credit Agreement, and assent to
extensions of time of payment or forbearance or other indulgence without
notice.

         This Note is a note executed in amendment and restatement in part of
the "Notes" as defined in the Amended Credit Agreement.

         IN WITNESS WHEREOF the undersigned has by its duly authorized
officers, executed this Note under seal as of the day and year first above
written.
