                  (g) References to "including" means including without limiting
         the generality of any description preceding such term, and for purposes
         hereof the rule of ejusdem generis shall not be applicable to limit a

         arithmetic expression shall be interpreted in accordance with the
         convention that 1% = 100 basis points.

                                   ARTICLE II

                              The Credit Facilities

         2.1. Revolving Loans.

                  (a) Commitment. Subject to the terms and conditions of this
Agreement, each Lender severally agrees to make Advances to the applicable
Borrower or Borrowers under the Revolving Credit Facility from time to time from
the Closing Date until the Revolving Credit Termination Date on a pro rata basis
as to the total borrowing requested by the applicable Borrower or Borrowers on
any day determined by such Lender's Applicable Commitment Percentage up to but
not exceeding the Revolving Credit Commitment of such Lender, provided, however,
that the Lenders will not be required and shall have no obligation to make any
such Advance (i) so long as a Default or an Event of Default has occurred and is
continuing or (ii) if the Agent has accelerated

                                       38
<PAGE>   39
the maturity of any of the Notes as a result of an Event of Default.
Notwithstanding anything to the contrary herein, however, immediately after
giving effect to each such Advance:

                  (i) the amount of Revolving Credit Outstandings shall not
         exceed the lesser of (A) the Total Revolving Credit Commitment and (B)
         the Maximum Available Amount; and

                  (ii) the amount of Revolving Credit Outstandings shall not
         exceed the Borrowing Base.

Within such limits, the Borrowers may borrow, repay and reborrow under the
Revolving Credit Facility on a Business Day from the Closing Date until, but (as
to borrowings and reborrowings) not including, the Revolving Credit Termination
Date; provided, however, that (A) no Revolving Loan that is a LIBOR Rate Loan
shall be made which has an Interest Period that extends beyond the Stated
Termination Date, and (B) each Revolving Loan that is a LIBOR Rate Loan may be
repaid only on the last day of the Interest Period with respect thereto unless
such payment is accompanied by the additional payment, if any, required by
Section 5.5.

                  (b) Amounts. Except as otherwise permitted by the Agent and
the Lenders from time to time, the amount of Revolving Credit Outstandings shall
not exceed at any time the limitations set in Sections 2.1(a)(i) and (ii), and,
in the event there shall be outstanding any such excess, the Borrowers shall
immediately make such payments and prepayments as shall be necessary to comply
with this restriction.

                  (c) Advances. (i) (A) An Authorized Representative shall give
the Agent (1) at least three (3) Business Days' irrevocable written notice by
telefacsimile transmission of a Borrowing Notice or Interest Rate Selection
Notice (as applicable) with appropriate insertions, effective upon receipt, of
each Loan that is a LIBOR Rate Loan (whether representing an additional
borrowing or the Continuation of a borrowing hereunder or the Conversion of a
borrowing hereunder from a Prime Rate Loan to a LIBOR Rate Loan) prior to 10:30
A.M. and (2) irrevocable written notice by telefacsimile transmission of a
Borrowing Notice or Interest Rate Selection Notice (as applicable) with
appropriate insertions, effective upon receipt, of each Loan that is a Prime
Rate Loan (whether representing an additional borrowing hereunder or the
Conversion of borrowing hereunder from a LIBOR Rate Loan to a Prime Rate Loan)
prior to 10:30 A.M. on the day of such proposed Loan. Each such notice shall be
effective upon receipt by the Agent, shall specify the amount of the borrowing,
the Type of Loan (Prime Rate or LIBOR Rate), and the date of borrowing. Notice
of receipt of such Borrowing Notice or Interest Rate Selection Notice, as the
case may be, together with the amount of each Lender's portion of an Advance
requested thereunder, shall be provided by the Agent to each Lender by
telefacsimile transmission with reasonable promptness, but (provided the Agent
shall have received such notice by 10:30 A.M.) not later than 1:00 P.M. on the
same day as the Agent's receipt of such notice.

                  (B) An Authorized Representative shall, simultaneously with
the delivery of a Borrowing Notice or Interest Rate Selection Notice (as
applicable) in accordance with Section 2.1(c)(i)(A), deliver to the Agent a
Borrowing Base Certificate dated as of such date, with

                                       39
<PAGE>   40
appropriate insertions, certifications and other attachments, which Borrowing
Base Certificate and all certifications and attachments shall be in form and
substance satisfactory to the Agent.

         (ii) Not later than 2:00 P.M. on the date specified for each borrowing
under this Section 2.1, each Lender shall, pursuant to the terms and subject to
the conditions of this Agreement, make the amount of the Advance or Advances to
be made by it on such day available by wire transfer to the Agent in the amount
of its pro rata share, determined according to such Lender's Applicable
Commitment Percentage of the Loan or Loans to be made on such day. Such wire
transfer shall be directed to the Agent at the Principal Office and shall be in
the form of Dollars constituting immediately available funds. The amount so
received by the Agent shall, subject to the terms and conditions of this
Agreement, be made available to the applicable Borrower or Borrowers by delivery
of the proceeds thereof to the applicable Borrower or Borrowers' Account(s) or
otherwise as shall be directed in the applicable Borrowing Notice by the
Authorized Representative and reasonably acceptable to the Agent.

                  (d) Repayment of Loans The principal amount of each Loan shall
be due and payable to the Agent for the benefit of each Lender in full on the
Revolving Credit Termination Date, or earlier as specifically provided herein.
The principal amount of any Loan may be prepaid in whole or in part on any
Business Day, upon (A) at least three (3) Business Days' irrevocable telephonic
notice in the case of each Loan that is a LIBOR Rate Loan from an Authorized
Representative (effective upon receipt) to the Agent prior to 10:30 A.M. and (B)
irrevocable telephonic notice in the case of each Loan that is a Prime Rate Loan
from an Authorized Representative (effective upon receipt) to the Agent prior to
10:30 A.M. on the day of such proposed repayment. The Authorized Representative
shall provide the Agent written confirmation of each such telephonic notice but
failure to provide such confirmation shall not effect the validity of such
telephonic notice. All prepayments of Loans made by the Borrower shall be in the
amount of $1,000,000 or such greater amount which is an integral multiple of
$1,000,000, or the amount equal to all Revolving Credit Outstandings, or such
other amount as necessary to comply with Section 2.1(b).

                  (e) Disposition of Property Prepayments. If any of the
Borrowers shall at any time agree to a Disposition, the Borrowers shall (i)
promptly notify the Agent of such Disposition, (ii) without limitation of the
requirements of Section 2.1(b), immediately upon such Disposition either (A)
place an Eligible Project of equivalent value in the Borrowing Base in
substitution of such disposed Project, or (B) repay the Loans in an amount equal
to the aggregate Disposition Net Proceeds of such Disposition, immediately upon
receipt thereof, and (iii) deliver a Borrowing Base Certificate reflecting the
removal of such Project.

                  (f) Reductions. The Borrowers shall, by notice from an
Authorized Representative, have the right from time to time but not more
frequently than once each calendar month, upon not less than three (3) Business
Days' written notice to the Agent, effective upon receipt, to reduce the Total
Revolving Credit Commitment. The Agent shall give each Lender, within one (1)
Business Day of receipt of such notice, telefacsimile notice, or telephonic
notice (confirmed in writing), of such reduction. Each such reduction shall be
in the aggregate amount of $1,000,000 or such greater amount which is in an
integral multiple of $1,000,000, or the entire remaining Total Revolving Credit
Commitment, and shall permanently reduce the Total Revolving Credit Commitment.
Each such reduction of the Total Revolving Credit Commitment shall reduce the
Maximum Available Amount by the same amount. Each reduction of the Total
Revolving Credit

                                       40
<PAGE>   41
Commitment shall be accompanied by payment of the Loans to the extent that the
principal amount of Revolving Credit Outstandings exceeds the lesser of (i) the
Total Revolving Credit Commitment and (ii) the Maximum Available Amount, after
giving effect to such reduction, together with accrued and unpaid interest on
the amounts prepaid.

                  (g) Notwithstanding any other provision of this Agreement,
except as hereinafter provided, each Borrower shall be jointly and severally
liable as primary obligor and not merely as surety for repayment of all
Obligations arising under the Loan Documents. Such joint and several liability
shall apply to each Borrower regardless of whether (i) any Loan was only
requested on behalf of or made to another Borrower or the proceeds of any Loan
were used only by another Borrower, (ii) any interest rate election was made
only on behalf of another Borrower, or (iii) any indemnification obligation or
any other obligation arose only as a result of the actions of another Borrower;
provided the liability of each of the Borrowers other than HCN under this
Agreement, the Notes and the other Loan Documents shall be limited to the
maximum amount of the Obligations under the Revolving Credit Facility for which
such other Borrower may be liable without violating any applicable fraudulent
conveyance, fraudulent transfer or comparable laws. Each Borrower shall retain
any right of contribution arising under applicable law against the other
Borrowers as the result of the satisfaction of any Obligations; provided, such
rights are hereby fully subordinated in all respects to the payment in full of
the Obligations, no Borrower shall assert such right of contribution against any
other Borrower until the Obligations shall have been paid in full, and each
Borrower shall hold in trust and separate from its other property any funds or
other property received on account of any such right of contribution and pay the
same over to the Agent for application to the Obligations until payment in full
of the Obligations.

         Without limiting the foregoing provisions of this Section 2.1(g), HCN
hereby irrevocably, absolutely and unconditionally guarantees the full and
punctual payment or performance when due, whether at stated maturity, by
required prepayment, declaration, acceleration, demand or otherwise, of all
Obligations of each other Borrower whether owing to the Agent or any Lender.
This guarantee constitutes a guaranty of payment and not of collection.

         It is the intention of the parties that with respect to each Borrower
its obligations under the immediately preceding two paragraphs shall be
absolute, unconditional and irrevocable irrespective of:

                           (i) any lack of validity, legality or enforceability
                  of this Agreement, any Note, or any other Loan Document as to
                  any other Borrowers;

                           (ii) the failure of the Agent or any Lender:

                                    (A) to enforce any right or remedy against
                           any other Borrower or any other Person under the
                           provisions of this Agreement, any Note, any other
                           Loan Document or otherwise, or

                                       41
<PAGE>   42
                                    (B) to exercise any right or remedy against
                           any guarantor of, or Collateral securing, any
                           Obligations;

                           (iii) any change in the time, manner or place of
                  payment of, or in any other term of, all or any of the
                  Obligations, or any other extension, compromise or renewal of
                  any Obligations with respect to any other Borrower;

                           (iv) any reduction, limitation, impairment or
                  termination of any Obligations with respect to any other
                  Borrower or any other Person for any reason including any
                  claim of waiver, release, surrender, alteration or compromise,
                  and shall not be subject to (and each Borrower hereby waives
                  any right to or claim of) any defense or setoff, counterclaim,
                  recoupment or termination whatsoever by reason of the
                  invalidity, illegality, nongenuineness, irregularity,
                  compromise or unenforceability of, or any other event or
                  occurrence affecting, any Obligations with respect to any
                  other Borrower;

                           (v) any addition, exchange, release, surrender or
                  nonperfection of any collateral, or any amendment to or waiver
                  or release or addition of, or consent to departure from , any
                  guaranty, held by the Agent, any Lender or any holder of any
                  Note securing any of the Obligations; or

                           (vi) any other circumstance which might otherwise
                  constitute a defense available to, or a legal or equitable
                  discharge of, any other Borrower, any surety or any guarantor.

         Each Borrower agrees that its joint and several liability hereunder
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment (in whole or in part) of any of the Obligations is rescinded or
must be restored by the Agent, any Lender or any holder of any Note, upon the
insolvency, bankruptcy or reorganization of any other Borrower as though such
payment had not been made.

         Each Borrower hereby expressly waives: (a) notice of the Lenders'
acceptance of this Agreement; (b) notice of the existence or creation or
non-payment of all or any of the Obligations; (c) notice of the addition of
Borrowing Subsidiaries or the release of any Borrower, (d) presentment, demand,
notice of dishonor, protest, and all other notices whatsoever other than notices
expressly provided for in this Agreement or by applicable law and (e) all
diligence in collection or protection of or realization upon the Obligations or
any thereof, any obligation hereunder, or any security for or guaranty of any of
the foregoing.

         No delay on any of the Lenders' or the Agent's part in the exercise of
any right or remedy shall operate as a waiver thereof, and no single or partial
exercise by any of the Lenders or the Agent of any right or remedy shall
preclude any other or further exercise thereof or the exercise of any other
right or remedy. No action of the Agent or any of the Lenders permitted
hereunder shall in any way affect or impair any of their rights or any of their
obligations to any of the Borrowers under this Agreement (except as otherwise
waived, modified, or amended).

                                       42
<PAGE>   43
         2.2. Use of Proceeds. The proceeds of the Loans hereunder shall be used
by the Borrowers for funding advances with respect to Eligible Projects, for
general working capital needs, and for other corporate purposes.

         2.3. Notes. Loans made by each Lender shall be evidenced by the Note or
Notes payable to the order of such Lender in the respective amount of its
Applicable Commitment Percentage of the lesser of (i) the Total Revolving Credit
Commitment and (ii) the Maximum Available Amount, which Note or Notes shall be
dated the Closing Date or a later date pursuant to either an Assignment and
Acceptance or the addition of a Borrowing Subsidiary, and shall be duly
completed, executed and delivered by the Borrowers as of the date of execution
thereof; provided, however, that at all times during which the Total Revolving
Credit Commitment shall exceed the Maximum Available Amount, the Note or Notes
payable to Bank United shall include such excess amount.

         2.4. Designation of Borrowing Subsidiaries. With the consent of the
Agent, HCN may from time to time designate any wholly-owned direct or indirect
Subsidiary of HCN which has not joined in the execution of this Agreement as a
"Borrowing Subsidiary" and a "Borrower" hereunder under the Revolving Credit
Facility by causing such Subsidiary to execute and deliver a duly completed
Assumption Letter in the form attached hereto as Exhibit J to the Agent, with
the written consent of HCN and the Agent at the foot thereof. Upon such
execution, delivery and consent such Subsidiary shall for all purposes be a
party hereto as a Borrowing Subsidiary and a Borrower as fully as if it had
executed and delivered this Agreement and the Notes. So long as all Obligations
supported by the Project Borrowing Bases of Projects as to which such Borrowing
Subsidiary is the owner or mortgagee under this Agreement shall have been paid
in full and all other obligations of the Subsidiary under the Credit Agreement
shall have been fully performed, and there shall not then have occurred and be
continuing a Default or Event of Default, such Borrowing Subsidiary may, by not
less than five (5) Business Days' prior notice to the Agent (which shall
promptly notify the Lenders thereof), terminate its status as a "Borrowing
Subsidiary" and a "Borrower" hereunder; subject to continuing liability under
Sections 8.13 and 12.9 to the extent applicable.

                                   ARTICLE III

                  LIBOR Funding, Fees, and Payment Conventions

         3.1. Interest Rate Options. LIBOR Rate Loans and Prime Rate Loans may
be outstanding at the same time and, so long as no Default or Event of Default
shall have occurred and be continuing, the Borrowers, through an Authorized
Representative, shall have the option to elect the Type of Loan and to Convert
Loans in accordance with Sections 2.1(c)(i) and 3.2, as applicable; provided,
however, (a) there shall not be outstanding at any one time LIBOR Rate Loans
having more than three (3) different Interest Periods, (b) each LIBOR Rate Loan
(including each Conversion into and each Continuation as a LIBOR Rate Loan)
shall be in an amount of $3,000,000 or, if greater than $3,000,000, an integral
multiple of $500,000, and (c) no LIBOR Rate Loan shall have an Interest Period
that extends beyond the Stated Termination Date. If the Agent does not receive a
Borrowing Notice or an Interest Rate Selection Notice giving notice of a LIBOR
Rate Loan or of Conversion of any Loan to or Continuation of a Loan as a LIBOR
Rate Loan by the time prescribed by Sections 2.1(c)(i) and 3.2, as applicable,
the Borrowers shall be deemed to have elected to obtain

                                       43
<PAGE>   44
or Convert such Loan to (or Continue such Loan as) a Prime Rate Loan until the
Borrowers notify the Agent in accordance with Section 3.2. The Borrowers shall
not be entitled to elect to Continue any Loan as or Convert any Loan into a
LIBOR Rate Loan if a Default or Event of Default shall have occurred and be
continuing.

         3.2. Conversions and Elections of Subsequent Interest Periods. Subject
to the limitations set forth in the definition of "Interest Period," in Section
3.1 and in Article V, the applicable Borrower or Borrowers may:

         (a) upon delivery, effective upon receipt, of a properly completed
Interest Rate Selection Notice to the Agent (which shall be irrevocable) on or
before 10:30 A.M. on any Business Day, Convert any LIBOR Rate Loan to a Prime
Rate Loan on the last day of the Interest Period for such LIBOR Rate Loan; and

         (b) provided that no Default or Event of Default shall have occurred
and be continuing, upon delivery, effective upon receipt, of a properly
completed Interest Rate Selection Notice to the Agent (which shall be
irrevocable) on or before 10:30 A.M. three (3) Business Days' prior to the date
of such Conversion or Continuation:

                  (i) elect a subsequent Interest Period for any LIBOR Rate Loan
         to begin on the last day of the then current Interest Period for such
         LIBOR Rate Loan; or

                  (ii) Convert any Prime Rate Loan to a LIBOR Rate Loan on any
         Business Day.

Each such notice shall be effective upon receipt by the Agent, shall specify the
amount of the LIBOR Rate Loan affected. Notice of receipt of such Interest Rate
Selection Notice shall be provided by the Agent to each Lender by telefacsimile
transmission with reasonable promptness, but (provided the Agent shall have
received such notice by 10:30 A.M.) not later than 3:00 P.M. on the same day as
the Agent's receipt of such notice. All such Continuations or Conversions of
Loans shall be effected pro rata based on the Applicable Commitment Percentages
of the Lenders.

         3.3. Payment of Interest. The Borrowers shall pay interest on the
outstanding and unpaid principal amount of each Loan, commencing on the first
date of such Loan until such Loan shall be repaid, at the applicable Prime Rate
or LIBOR Rate as designated by the Borrowers in the related Borrowing Notice or
Interest Rate Selection Notice or as otherwise provided hereunder. Interest on
each Loan shall be paid on the earlier of (a) in the case of any Prime Rate
Loan, monthly in arrears of the last Business Day of each month, commencing on
March 31, 1999, until the Revolving Credit Termination Date, at which date as
applicable the entire principal amount of and all accrued interest on the Loans
shall be paid in full, (b) in the case of any LIBOR Rate Loan, on last day of
the applicable Interest Period for such LIBOR Rate Loan, and (c) upon payment in
full of the related Loan; provided, however, that if any Event of Default shall
occur and be continuing, all amounts outstanding hereunder shall bear interest
thereafter until paid in full at the Default Rate.

         3.4. Prepayments of LIBOR Rate Loans. Whenever any payment of principal
shall be made in respect of any Loan hereunder, whether at maturity, on
acceleration, by optional or

                                       44
<PAGE>   45
mandatory prepayment or as otherwise required or permitted hereunder, with the
effect that any LIBOR Rate Loan shall be prepaid in whole or in part prior to
the last day of the Interest Period applicable to such LIBOR Rate Loan, such
payment of principal shall be accompanied by the additional payment, if any,
required by Section 5.5.

         3.5. Manner of Payment. (a) Each payment of principal (including any
prepayment) and payment of interest and fees, and any other amount required to
be paid by or on behalf of the Borrower to the Lenders or the Agent with respect
to any Loan shall be made to the Agent at the Principal Office in Dollars in
immediately available funds without setoff, deduction or counterclaim on or
before 12:30 P.M. on the date such payment is due. The Agent may, but shall not
be obligated to, debit the amount of such payment from any one or more ordinary
deposit accounts of any Borrower with the Agent.

         (b) Any payment made by or on behalf of any Borrower that is not made
both in Dollars in immediately available funds and prior to 12:30 P.M. on the
date such payment is to be made shall constitute a non-conforming payment. Any
such non-conforming payment shall not be deemed to be received until the later
of (i) the time such funds become available funds and (ii) the next Business
Day. Any non-conforming payment may constitute or become a Default or Event of
Default as otherwise provided herein. Interest shall continue to accrue at the
Default Rate on any principal or fees as to which no payment or a non-conforming
payment is made from the date such amount was due and payable until the later of
(i) the date such funds become available funds or (ii) the next Business Day.

         (c) In the event that any payment hereunder or under any of the Notes
becomes due and payable on a day other than a Business Day, then such due date
shall be extended to the next succeeding Business Day unless provided otherwise
under the definition of "Interest Period"; provided, however, that interest
shall continue to accrue during the period of any such extension; and provided
further, however, that in no event shall any such due date be extended beyond
the Revolving Credit Termination Date.

         3.6. Fees. (a) Unused Fee. For the period beginning on April 10, 1999
and ending on the Revolving Credit Termination Date, the Borrowers agree to pay
to the Agent, for the pro rata benefit of the Lenders based on their Applicable
Commitment Percentages, an unused fee equal to the Unused Fee multiplied by the
average daily amount by which the lesser of (i) the Total Revolving Credit
Commitment and (ii) the Maximum Available Amount exceeds the Revolving Credit
Outstandings. Such fees shall be due in arrears on the last Business Day of each
fiscal quarter commencing April 30, 1999 to and on the Revolving Credit
Termination Date. Notwithstanding the foregoing, so long as any Lender fails to
make available any portion of its Revolving Credit Commitment when requested,
such Lender shall not be entitled to receive payment of its pro rata share of
such fee until such Lender shall make available such portion.

         (b) Borrowing Base Administration Fee. The Borrowers agree to pay to
the Agent, for its own account, a one-time fee for each Project for which the
Borrowers seek inclusion as an Eligible Project in the Borrowing Base, in the
amount of $5,000. This fee shall be paid to the Agent simultaneously with the
delivery by the applicable Borrower or Borrowers of the initial Eligible

                                       45
<PAGE>   46
Project Certificate with respect to such Project. No refund of this fee shall be
made in the event of the removal of any Project from the Borrowing Base, without
regard to the reason for such removal.

         (c) Other Fees. The Borrower agree to pay to the Agent or any Lender
all other fees due and owing pursuant to any written agreement from time to
between any Borrower, the Agent or any Lender, or any of them.

         3.7. Pro Rata Payments. Except as otherwise specified herein, (a) each
payment on account of the principal of and interest on Loans and the fees
described in Section 3.6(a), shall be made to the Agent for the account of the
Lenders pro rata based on their Applicable Commitment Percentages, and (b) the
Agent will promptly distribute to the Lenders in immediately available funds
payments received in fully collected, immediately available funds from the
Borrowers.

         3.8. Computation of Rates and Fees. Except as may be otherwise
expressly provided, all interest rates (including the Prime Rate, each LIBOR
Rate, and the Default Rate) and fees shall be computed on the basis of a year of
360 days and calculated for actual days elapsed.

         3.9. Deficiency Advances; Failure to Purchase Participations. No Lender
shall be responsible for any default of any other Lender in respect to such
other Lender's obligation to make any Loan or Advance hereunder nor shall the
Revolving Credit Commitment of any Lender hereunder be increased as a result of
such default of any other Lender. Without limiting the generality of the
foregoing, in the event any Lender shall fail to advance funds to the Borrowers
as herein provided, the Agent may in its discretion, but shall not be obligated
to, advance under the applicable Note in its favor as a Lender all or any
portion of such amount or amounts (each, a "deficiency advance") and shall
thereafter be entitled to payments of principal of and interest on such
deficiency advance in the same manner and at the same interest rate or rates to
which such other Lender would have been entitled had it made such Advance under
its Note; provided that, (i) such defaulting Lender shall not be entitled to
receive payments of principal, interest or fees with respect to such deficiency
advance until such deficiency advance shall be paid by such Lender and (ii) upon
payment to the Agent from such other Lender of the entire outstanding amount of
each such deficiency advance, together with accrued and unpaid interest thereon,
from the most recent date or dates interest was paid to the Agent by the
Borrowers on each Loan comprising the deficiency advance at the interest rate
per annum for overnight borrowing by the Agent from the Federal Reserve Bank,
then such payment shall be credited against the applicable Note of the Agent in
full payment of such deficiency advance and the Borrowers shall be deemed to
have borrowed the amount of such deficiency advance from such other Lender as of
the most recent date or dates, as the case may be, upon which any payments of
interest were made by the Borrowers thereon.

                                   ARTICLE IV

                                    Security

         4.1. Security. As security for the full and timely payment and
performance of all Obligations, the Credit Parties shall on or before the
Closing Date do or cause to be done all things necessary in the opinion of the
Agent and its counsel to grant to the Agent for the benefit of the

                                       46
<PAGE>   47
Lenders a duly perfected first priority security interest in all property which
as at the Closing Date is required to be Collateral subject to no prior Lien or
other encumbrance or restriction on transfer.

         4.2. Further Assurances. At the request of the Agent, each of the
Borrowers will or will cause its Subsidiaries, as the case may be, to execute,
by its duly authorized officers, alone or with the Agent, any certificate,
instrument, statement or document, or to procure any such certificate,
instrument, statement or document, or to take such other action (and pay all
connected costs) which the Agent reasonably deems necessary from time to time to
create, continue or preserve the liens and security interests in Collateral (and
the perfection and priority thereof) of the Agent contemplated hereby and by the
other Loan Documents and specifically including all Collateral acquired by any
Borrower after the Closing Date.

         4.3. Information Regarding Collateral. Each of the Borrowers
represents, warrants and covenants that (i) the chief executive office of such
Borrower and each other Person providing Collateral pursuant to a Security
Instrument (each, a "Grantor") at the Closing Date is located at the address or
addresses specified on Schedule 4.3, and (ii) Schedule 4.3 contains a true and
complete list of (a) the name and address of each Grantor and of each other
Person that has effected any merger or consolidation with a Grantor or
contributed or transferred to a Grantor any property constituting Collateral at
any time since January 1, 1998 (excluding Persons making sales in the ordinary
course of their businesses to a Grantor of property constituting inventory in
the hands of such seller), (b) each location of the chief executive office of
each Grantor at any time since January 1, 1998, (c) each location in which goods
constituting Collateral are or have been located since January 1, 1998 (together
with the name of each owner of the property located at such address if not the
applicable Grantor, and a summary description of the relationship between the
applicable Grantor and such Person), (d) the location of each Project included
in the Borrowing Base, and (e) each trade style used by any Grantor since
January 1, 1998 and the purposes for which it was used. No Borrower shall
change, or permit any other Grantor to change, the location of its chief
executive office, its jurisdiction of formation or any location specified in
clause (c) or (d) of the immediately preceding sentence, or use or permit any
other Grantor to use any additional trade style, except upon giving not less
than thirty (30) days' prior written notice to the Agent and taking or causing
to be taken all such action at such Borrower's or such other Grantor's expense
as may be reasonably requested by the Agent to perfect or maintain the
perfection of the Lien of the Agent in Collateral.

         4.4. Security Agreements and Assignment Agreements. As security for the
full and timely payment and performance of all Obligations now existing or
hereafter arising, each Borrower agrees to deliver to the Agent, with respect to
each Project included in the Borrowing Base, prior to such inclusion, a Security
Agreement, an Assignment Agreement, the Uniform Commercial Code financing
statements, all documents referred to in the applicable Schedules to the initial
Eligible Project Certificate with respect to such Project, and each other
Security Instrument sufficient to grant to the Agent a valid, duly perfected
security interest in the Collateral described therein, including without
limitation the Project Collateral, subject to no prior Liens other than
Permitted Liens, and with respect to the Mortgages, no prior Liens other than
the Permitted Encumbrances as defined therein. Each of the Borrowers further
agrees, with respect to each Project to be included in the Borrowing Base, prior
to such inclusion, to cause each document described in the first sentence of
this Section 4.4 to be delivered to the Agent by any Subsidiary that becomes a
Borrowing Subsidiary

                                       47
<PAGE>   48
pursuant to Section 2.4 hereof. Further, with respect to each Project to be
included in the Borrowing Base after the Closing Date, prior to such inclusion,
to cause each document described in the first sentence of this Section 4.4, or
any supplement to any such document previously delivered, as applicable, to be
delivered to the Agent.

         4.5. Mortgages. As security for the full and timely payment and
performance of all Obligations now existing or hereafter arising, each Borrower
(as applicable) has heretofore delivered to the Agent, Mortgages with respect to
the real property of each Eligible Project included in the Borrowing Base as of
the Closing Date. Mortgages relating to real property in connection with any
Eligible Project that is included in the Borrowing Base after the date hereof
shall be delivered by the applicable Borrower simultaneously with the delivery
of the Eligible Project Certificate pursuant to which such Eligible Project is
permitted to be included in the Borrowing Base.

         4.6. Release of Liens. In the event that a Project is at any time
permanently removed from the Borrowing Base, so long as the Agent has received a
Borrowing Base Certificate reflecting the removal of such Project and
demonstrating that the amount of Revolving Credit Outstandings at such time
shall not exceed either (A) the Borrowing Base (as calculated following removal
of such Project from the Borrowing Base), or (B) the lesser of the Maximum
Available Amount and the Total Revolving Credit Commitment, then the Agent and
the Lenders shall release any Lien on any Collateral pertaining solely to such
Project, and shall execute such documents and take such other actions that, in
the reasonable judgment of the Borrowers and the Agent, are necessary to
effectuate such release, all at the sole reasonable request of an Authorized
Representative and at the expense of the Borrowers.

                                    ARTICLE V

                             Change in Circumstances

         5.1. Additional Costs; Capital Requirements.

         (a) In the event that any existing or future law or regulation,
guideline, or interpretation thereof, by any Governmental Authority charged with
the administration thereof, or compliance by any Lender with any request or
directive (whether or not having the force of law) of any such authority shall
impose, modify or deem applicable or result in the application of, any capital
maintenance, capital ratio or similar requirement against loan commitments made
by any Lender hereunder, and the result of any event referred to above is to
impose upon any Lender or increase any capital requirement applicable as a
result of the making or maintenance of such Lender's Revolving Credit Commitment
or the obligation of the Borrowers hereunder with respect to such Revolving
Credit Commitment (which imposition of capital requirements may be determined by
each Lender's reasonable allocation of the aggregate of such capital increases
or impositions), then, within ten (10) Business Days of demand made by such
Lender as promptly as practicable after it obtains knowledged that such law,
regulation, guideline, interpretation, requires or directive exists and
determines to make such demand, the Borrowers shall pay to such Lender from time
to time as specified by such Lender additional amounts which shall be sufficient
to compensate such Lender for such imposition of or increase in capital
requirements together with interest on each such amount

                                       48
<PAGE>   49
from the date demanded until payment in full thereof at the Default Rate. A
certificate setting forth in reasonable detail the amount necessary to
compensate such Lender as a result of an imposition of or increase in capital
requirements submitted by such Lender to the Borrowers shall be conclusive,
absent manifest error, as to the amount thereof. All references to any Lender
shall be deemed to include any participant in such Lender's Revolving Credit
Commitment.

         (b) In the event that any Regulatory Change shall: (i) change the basis
of taxation of any amounts payable to any Lender under this Agreement or the
Notes in respect of any Loans including, without limitation, LIBOR Rate Loans
(other than taxes imposed on the overall net income of such Lender for any such
Loans by the United States of America or the jurisdiction in which such Lender
has its principal office); or (ii) impose or modify any reserve, Federal Deposit
Insurance Corporation premium or assessment, special deposit or similar
requirements relating to any extensions of credit or other assets of, or any
deposits with or liabilities of, such Lender (including any of such Loans or any
deposits referred to in the definition of "LIBOR Base Rate"); or (iii) impose
any other conditions affecting this Agreement in respect of Loans, including,
without limitation, LIBOR Rate Loans (or any of such extensions of credit,
assets, deposits or liabilities); and the result of any event referred to in
clause (i), (ii) or (iii) above shall be to increase such Lender's costs of
making or maintaining any Loans including, without limitation, LIBOR Rate Loans,
or its Revolving Credit Commitment, or to reduce any amount receivable by such
Lender hereunder in respect of its Revolving Credit Commitment (such increases
in costs and reductions in amounts receivable are hereinafter referred to as
"Additional Costs") in each case, only to the extent, with respect to LIBOR Rate
Loans, that such Additional Costs are not included in the LIBOR Rate applicable
to LIBOR Rate Loans, then, within ten (10) Business Days of demand made by such
Lender as promptly as practicable after it obtains knowledge that such a
Regulatory Change exists and determines to make such demand (a copy of which
demand shall be delivered to the Agent), the Borrowers shall pay to such Lender
from time to time as specified by such Lender, additional amounts which shall be
sufficient to compensate such Lender for such increased cost or reduction in
amounts receivable by such Lender from the date of such change, together with
interest on each such amount from the date demanded until payment in full
thereof at the Default Rate. All references to any Lender shall be deemed to
include any participant in such Lender Revolving Credit Commitment.

         (c) Without limiting the effect of the foregoing provisions of this
Section 5.1, in the event that, by reason of any Regulatory Change, any Lender
either: (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
LIBOR Rate Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes LIBOR Rate
Loans, or (ii) becomes subject to restrictions on the amount of such a category
of liabilities or assets that it may hold, then, if such Lender so elects by
notice to the Borrowers (with a copy to the Agent), the obligation of such
Lender to make, and to convert Loans of any other Type into, Loans of such Type
hereunder shall be suspended until the date such Regulatory Change ceases to be
in effect (and all Loans of such Type then outstanding shall be Converted into
Prime Rate Loans).

         (d) Determinations by any Lender for purposes of this Section 5.1 of
the effect of any Regulatory Change on its costs of making or maintaining Loans
or on amounts receivable by it in

                                       49
<PAGE>   50
respect of Loans, and of the additional amounts required to compensate such
Lender in respect of any Additional Costs, shall be set forth in writing in
reasonable detail describing the Additional Costs together with a calculation
demonstrating the allocation to the Borrowers of such Additional Costs which
shall be conclusive, absent manifest error.

         5.2. Limitation on Types of Loans. Anything herein to the contrary
notwithstanding, if, on or prior to the determination of an interest rate for
any LIBOR Rate Loans for any Interest Period therefor, the Required Lenders
determine (which determination shall be conclusive):

         (a) by reason of any event affecting the money markets in the United
States of America or the London interbank market, quotations of interest rates
for the relevant deposits are not being provided in the relevant amounts or for
the relevant maturities for purposes of determining the rate of interest for
such Loans under this Agreement; or

         (b) the rates of interest referred to in the definition of "LIBOR Base
Rate" in Section 1.1 hereof upon the basis of which the rate of interest on any
LIBOR Rate Loans for such period is determined, do not accurately reflect the
cost to the Lenders of making or maintaining such Loans for such period; then
the Agent shall give the Borrowers and each Lender prompt notice thereof (and
shall thereafter give the Borrowers and each Lender prompt notice of the
cessation, if any, of such condition), and so long as such condition remains in
effect, the Lenders shall be under no obligation to make Loans of such Type or
to Convert Loans of any other Type into Loans of such Type and the Borrowers
shall, on the last day(s) of the then current Interest Period(s) for the
outstanding Loans of the affected Type either prepay such Loans or Convert such
Loans into another Type of Loan in accordance with the terms of this Agreement.

         5.3. Illegality. Notwithstanding any other provision in this Agreement,
in the event that it becomes unlawful for any Lender or its applicable Lending
Office to: (a) honor its obligation to make LIBOR Rate Loans hereunder, or (b)
maintain LIBOR Rate Loans hereunder, then such Lender shall promptly notify the
Borrowers thereof (with a copy to the Agent), describing such illegality in
reasonable detail (and shall thereafter promptly notify the Borrowers and the
Agent of the cessation, if any, of such illegality), and such Lender's
obligation to make LIBOR Rate Loans, to Continue LIBOR Rate Loans and to Convert
Prime Rate Loans into LIBOR Rate Loans hereunder shall, upon written notice
given by such Lender to the Borrowers, be suspended until such time as such
Lender may again make and maintain LIBOR Rate Loans and such Lender's
outstanding LIBOR Rate Loans shall be prepaid or Converted into another Type of
Loan in accordance with the terms of this Agreement.

         5.4. Certain Conversions. If the Loans of any Lender of a particular
Type (Loans of such Type are hereinafter referred to as "Affected Loans" and
such Type is hereinafter referred to as the "Affected Type") are to be
Converted, such Lender's Affected Loans shall automatically be Converted into
Prime Rate Loans on the last day(s) of the then current Interest Period(s) for
the Affected Loans (or, in the case of a Conversion required by Section 5.1(b)
or Section 5.3 hereof, on such earlier date as such Lender may specify to the
Borrowers with a copy to the Agent) and, unless and until such Lender gives
notice as provided below that the circumstances specified in Section 5.1(b) or
Section 5.3 that gave rise to such Conversion no longer exist:

                                       50
<PAGE>   51
         (a) to the extent that such Lender's Affected Loans have been so
Converted, all payments and prepayments of principal that would otherwise be
applied to such Lender's Affected Loans shall be applied instead to its Prime
Rate Loans; and

         (b) all Loans which would otherwise be made or Continued by such Lender
as Loans of the Affected Type shall be made or Converted instead as Prime Rate
Loans, and all Loans of such Lender that would otherwise be Converted into Loans
of the Affected Type shall be Converted instead into (or shall remain as) Prime
Rate Loans.

         5.5. Compensation. The Borrowers shall pay to the Agent for the account
of each Lender, upon the request of such Lender through the Agent, such amount
or amounts as shall compensate such Lender for any loss (including loss of
profit), cost or expense incurred by such Lender (as reasonably determined by
such Lender) as a result of:

         (a) any payment or repayment or conversion of a LIBOR Rate Loan held by
such Lender on a date other than the last day of an Interest Period for such
LIBOR Rate Loan except pursuant to Sections 5.1 or 5.3 hereof; or

         (b) any failure by the Borrowers to borrow a LIBOR Rate Loan on the
date for such borrowing specified in the relevant Borrowing Notice; such
compensation to include, without limitation, an amount equal to: (i) any loss or
expense suffered by such Lender during the period from the date of receipt of
such early payment or repayment or the date of such conversion to the last day
of such Interest Period if the rate of interest obtainable by such Lender upon
the redeployment of an amount of funds equal to such Lender's pro rata share of
such payment, repayment or Conversion or failure to borrow or Convert is less
than the rate of interest applicable to such LIBOR Rate Loan for such Interest
Period, or (ii) any loss or expense suffered by such Lender in liquidating LIBOR
deposits prior to maturity which correspond to such Lender's pro rata share of
such payment, repayment, Conversion, failure to borrow or failure to Convert.
The determination by each such Lender of the amount of any such loss or expense,
when set forth in a written notice to the Borrowers, containing such Lender's
calculation thereof in reasonable detail, shall be presumed correct, in the
absence of manifest error.

         5.6. Taxes. If, under any law in effect on the date of the closing of
any Loan hereunder, or under any retroactive provision of any law subsequently
enacted, it shall be determined that any Federal, state or local tax is payable
in respect of the issuance of any Note, or in connection with the filing or
recording of any assignments, mortgages, financing statements, or other
documents (whether measured by the amount of Indebtedness secured or otherwise)
as contemplated by this Agreement, then the Borrowers will pay any such tax and
all interest and penalties, if any, and will indemnify the Lenders and the Agent
against and save each of them harmless from any loss or damage resulting from or
arising out of the nonpayment or delay in payment of any such tax. If any such
tax or taxes shall be assessed or levied against any Lender or any other holder
of a Note, such Lender, or such other holder, as the case may be, may notify
each Borrower and make immediate payment thereof, together with interest or
penalties in connection therewith, and shall thereupon be entitled to and shall
receive immediate reimbursement therefor from each Borrower.

                                       51
<PAGE>   52
Notwithstanding any other provision contained in this Agreement, the covenants
and agreements of the Borrowers in this Section 5.6 shall survive payment of the
Obligations and the occurrence of the Facility Termination Date.

         5.7. Delivery of Tax Forms. Each Lender not organized under the laws of
the United States or a state thereof shall:

         (a) deliver to the Borrowers and the Agent, on or prior to the date of
its execution and delivery of this Agreement in the case of each Lender listed
on the signature pages hereof and on or prior to the date on which it becomes a
Lender in the case of each other Lender, (i) two accurate and duly completed
executed copies of Internal Revenue Service Form 1001 or 4224, as appropriate,
or any successor form prescribed by the Internal Revenue Service, and (ii) an
accurate and complete Internal Revenue Service Form W-8 or W-9, as appropriate,
or any successor form prescribed by the Internal Revenue Service, as the case
may be; and

         (b) deliver to the Borrowers and to the Agent two further accurate and
complete executed copies of any such form or certification on or before the date
that any such form or certification expires or becomes obsolete and after the
occurrence of any event requiring a change in the most recent form previously
delivered by it to the Borrowers; and

         (c) obtain such extensions of time for filing and completing such forms
or certifications as may reasonably be requested by the Borrowers or the Agent;
unless in any such case under clause (b) above an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form with respect to it and such Lender so advises the
Borrowers and the Agent. Such Lender shall certify (i) in the case of Internal
Revenue Service Form 1001 or 4224 that is provided pursuant to clause (a) above,
that it is entitled to receive payments under this Agreement without deduction
or withholding of any United States Federal income taxes; (ii) in the case of
any Internal Revenue Service Form 1001 or 4224 that is provided pursuant to
clause (b) above, to the extent legally entitled to do so, that it is entitled
to receive payments under this Agreement without, or at a reduced rate of,
deduction or withholding of any United States Federal income taxes; and (iii) in
the case of an Internal Revenue Service Form W-8 or W-9, that it is entitled to
an exemption from United States backup withholding tax. Each Person not
organized under the laws of the United States or a state thereof that is an
assignee hereunder shall, prior to the effectiveness of the related transfer, be
required to provide all of the forms and statements required pursuant to this
Section 5.7.

                         Representations and Warranties

         Each of the Borrowers represents and warrants with respect to itself
and to its Subsidiaries (which representations and warranties shall survive the

presently engaged and in which it proposes to be engaged.

         (b) Each Borrower is in good standing in its state of organization and
in each state in which it is qualified to do business. There are no
jurisdictions other than as set forth on Schedule 7.1 hereto in which the
character of the properties owned or proposed to be owned by each Borrower or in
which the transaction of the business of each Borrower as now conducted or as
proposed to be conducted requires or will require such Borrower to qualify to do
business and as to which failure so to qualify could have a Material Adverse
Effect on such Borrower.

         7.2. Power, Authority, Consents. Each Borrower has the power to
execute, deliver and perform the Loan Documents to be executed by it. Each
Borrower has the power to borrow hereunder and has taken all necessary corporate
action to authorize the borrowing hereunder on the terms and conditions of this
Agreement. Each Borrower has taken all necessary action, corporate or otherwise,
to authorize the execution, delivery and performance of the Loan Documents to be
executed by it. No consent or approval of any Person (including, without
limitation, any stockholder of any Borrower), no consent or approval of any
landlord or mortgagee, no waiver of any Lien or right of distraint or other
similar right and no consent, license, certificate of need, approval,

obtained on or prior to the date hereof and is now in full force and effect, or
is designated on Schedule 7.2 as waived by the Required Lenders.

         7.3. No Violation of Law or Agreements. The execution and delivery by
each Borrower of each Loan Document to which it is a party and performance by it
hereunder and thereunder, will not violate any provision of law and will not
conflict with or result in a breach of any order, writ, injunction, ordinance,
resolution, decree, or other similar document or instrument of any court or
governmental authority, bureau or agency, domestic or foreign, or any
certificate of incorporation or by-laws of each Borrower, or create (with or
without the giving of notice or lapse of time, or both) a default under or
breach of any agreement, bond, note or indenture to which any Borrower is a
party, or by which any Borrower is bound or any of their respective properties
or assets is affected, except for such defaults and breaches which in the
aggregate could not have a Material Adverse Effect on

                                       57
<PAGE>   58
the Borrowers, or result in the imposition of any Lien of any nature whatsoever
upon any of the properties or assets owned by or used in connection with the
business of each Borrower.

         7.4. Due Execution, Validity and Enforceability. This Agreement and
each other Loan Document to which each Borrower is a party has been duly
executed and delivered by each Borrower that is a party thereto and each
constitutes the valid and legally binding obligation of each Borrower,
enforceable in accordance with its terms, except as such enforcement may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium, or
other similar laws, now or hereafter in effect, relating to or affecting the
enforcement of creditors' rights generally and except that the remedy of
specific performance and other equitable remedies are subject to judicial
discretion.

Adverse Effect.

7.8 hereto, there are no outstanding judgments, investigations, actions or
proceedings, including, without limitation, any Environmental Proceeding,

proceeding, a claim in excess of Two Hundred Fifty Thousand ($250,000) Dollars,
nor, to the best of each Borrower's knowledge, is there any reasonable basis for
the institution of any such action or proceeding that is probable of assertion,
nor are there any such actions or proceedings in which any Borrower is a
plaintiff or complainant.

         7.9. No Defaults; Compliance With Laws. Except as set forth on Schedule
7.9 hereto, none of the Borrowers is in default under any agreement, ordinance,
resolution, decree, bond, note, indenture, order or judgment to which it is a

such Borrower. Each Borrower has complied and is in compliance in all respects
with all applicable laws, ordinances and regulations, resolutions, ordinances,
decrees and other similar documents and instruments of all courts and
governmental authorities, bureaus and agencies, domestic and foreign, including,
without limitation, all applicable provisions of the Americans with Disabilities
Act (42 U.S.C. 12101-12213) and the regulations issued thereunder and all

         to the Agent, in its sole discretion, shall have become and shall have
         commenced to perform the duties of such executive officer of HCN and
         serve as a member of HCN's Board of Directors within thirty (30) days
         after such cessation; provided, however, that if any satisfactory
         successor shall have been so elected and shall have commenced
         performance of such duties within such period, the name of such
         successor or successors shall be deemed to have been inserted in place
         of George L. Chapman in this Section 10.1(o); or

                  (q) any of the Borrowers or any of their respective Projects
         shall become subject to one or more Liens for costs or damages in
         excess of One Million ($1,000,000) Dollars individually or in the
         aggregate under any Environmental Laws and Regulations, such Liens
         shall remain in place for thirty (30) days after the creation thereof
         and such Liens are reasonably likely to cause a Material Adverse
         Effect; or

                                       78
<PAGE>   79
                  (r) thirty (30) days after the acceleration by any Borrower of
         the obligations of an Operator as a result of any default in the
         payment of amounts which are due and owing under any lease, note,
         mortgage or related security documents in connection with any Project
         of such Operator (such Project, herein referred to as the "Defaulted
         Project"), in the event the sum of Lease Rental Expense and/or Mortgage
         Expense arising from (i) the Defaulted Project, and (ii) all Pooled
         Projects, if any, of which the Defaulted Project is a part, which have
         a Fixed Charge Coverage of less than 1.0 to 1.0, account for 12.50% or
         more of the aggregate amount of all Lease Rental Expense and/or
         Mortgage Expense owing to the Borrowers from all Operators during the
         immediately preceding four (4) calendar quarters; or

                  (s) if there shall occur and not be waived an Event of Default
         as defined in any of the other Loan Documents;

then, and in any such event and at any time thereafter, if such Event of Default
or any other Event of Default shall have not been waived,

                  (A) either or both of the following actions may be taken: (i)
         the Agent, with the consent of the Required Lenders, may, and at the
         direction of the Required Lenders shall, declare any obligation of the
         Lenders to make further Loans terminated, whereupon the obligation of
         each Lender to make further Loans hereunder shall terminate
         immediately, and (ii) the Agent shall at the direction of the Required
         Lenders, at their option, declare by notice to the Borrowers any or all
         of the Obligations to be immediately due and payable, and the same,
         including all interest accrued thereon and all other obligations of any
         Borrower to the Agent and the Lenders, shall forthwith become
         immediately due and payable without presentment, demand, protest,
         notice or other formality of any kind, all of which are hereby
         expressly waived, anything contained herein or in any instrument
         evidencing the Obligations to the contrary notwithstanding; provided,
         however, that notwithstanding the above, if there shall occur an Event
         of Default under clause (f), (g) or (h) above, then the obligation of
         the Lenders to make Loans hereunder shall automatically terminate and
         any and all of the Obligations shall be immediately due and payable
         without the necessity of any action by the Agent or the Required
         Lenders or notice to the Agent or the Lenders; and

                  (B) the Agent and each of the Lenders shall have all of the
         rights and remedies available under the Loan Documents or under any
         applicable law.

         10.2. Agent to Act. In case any one or more Events of Default shall
occur and not have been waived, the Agent may, and at the direction of the
Required Lenders shall, proceed to protect and enforce their rights or remedies
either by suit in equity or by action at law, or both, whether for the specific
performance of any covenant, agreement or other provision contained herein or in
any other Loan Document, or to enforce the payment of the Obligations or any
other legal or equitable right or remedy.

         10.3. Cumulative Rights. No right or remedy herein conferred upon the
Lenders or the Agent is intended to be exclusive of any other rights or remedies
contained herein or in any other

                                       79
<PAGE>   80
Loan Document, and every such right or remedy shall be cumulative and shall be
in addition to every other such right or remedy contained herein and therein or
now or hereafter existing at law or in equity or by statute, or otherwise.

                                       80
<PAGE>   81
         10.4. No Waiver. No course of dealing between any Borrower and any
Lender or the Agent or any failure or delay on the part of any Lender or the
Agent in exercising any rights or remedies under any Loan Document or otherwise
available to it shall operate as a waiver of any rights or remedies and no
single or partial exercise of any rights or remedies shall operate as a waiver
or preclude the exercise of any other rights or remedies hereunder or of the
same right or remedy on a future occasion.

         10.5. Allocation of Proceeds. If an Event of Default has occurred and
not been waived, and the maturity of the Notes has been accelerated pursuant to
Article X hereof, all payments received by the Agent hereunder, in respect of
any principal of or interest on the Obligations or any other amounts payable by
the Borrower hereunder, shall be applied by the Agent in the following order:

                  (a) the reasonable expenses incurred in connection with
         retaking, holding, preserving, processing, maintaining or preparing for
         sale, lease or other disposition of, any Collateral, including
         reasonable attorney's fees and legal expenses pertaining thereto;

                  (b) amounts due to the Lenders pursuant to Sections 3.6(a),
         3.6(b) and 12.5;

                  (c) amounts due to the Agent pursuant to Section 3.6(c);

                  (d) payments of interest on Loans, to be applied for the
         ratable benefit of the Lenders;

                  (e) payments of principal of Loans, to be applied for the
         ratable benefit of the Lenders;

                  (f) amounts due to the Agent and the Lenders pursuant to
         Sections 8.13 and 12.9;

                  (g) payments of all other amounts due under any of the Loan
         Documents, if any, to be applied for the ratable benefit of the
         Lenders;

                  (h) amounts due to any of the Lenders in respect of
         Obligations consisting of liabilities under any Swap Agreement with any
         of the Lenders on a pro rata basis according to the amounts owed; and

                  (i) any surplus remaining after application as provided for
         herein, to the Borrower or otherwise as may be required by applicable
         law.

                                   ARTICLE XI

                                    The Agent

         11.1. Appointment, Powers, and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Agent to act as its agent under this
Agreement and the other Loan Documents with such powers and discretion as are
specifically delegated to the Agent by the terms of this Agreement and the other
Loan Documents, together with such other powers as are reasonably incidental
thereto. The Agent (which term as used in this sentence and in Section 11.5 and
the first sentence of Section 11.6 hereof shall include its affiliates and its
own and its affiliates' officers, directors, employees, and agents):

                  (a) shall not have any duties or responsibilities except those
         expressly set forth in this Agreement and shall not be a trustee or
         fiduciary for any Lender;

                  (b) shall not be responsible to the Lenders for any recital,
         statement, representation, or warranty (whether written or oral) made
         in or in connection with any Loan Document or any certificate or other
         document referred to or provided for in, or received by any of them
         under, any Loan Document, or for the value, validity, effectiveness,
         genuineness, enforceability, or sufficiency of any Loan Document, or
         any other document referred to or provided for therein or for any
         failure by any Credit Party or any other Person to perform any of its
         obligations thereunder;

                  (c) shall not be responsible for or have any duty to
         ascertain, inquire into, or verify the performance or observance of any
         covenants or agreements by any Credit Party or the satisfaction of any
         condition or to inspect the property (including the books and records)
         of any Credit Party or any of its Subsidiaries or affiliates;

                  (d) shall not be required to initiate or conduct any
         litigation or collection proceedings under any Loan Document; and

                  (e) shall not be responsible for any action taken or omitted
         to be taken by it under or in connection with any Loan Document, except
         for its own gross negligence or willful misconduct.

The Agent may employ agents and attorneys-in-fact and shall not be responsible
for the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.

                                       82
<PAGE>   83
         11.2. Reliance by Agent. The Agent shall be entitled to rely upon any
certification, notice, instrument, writing, or other communication (including,
without limitation, any thereof by telephone or telefacsimile) believed by it to
be genuine and correct and to have been signed, sent or made by or on behalf of
the proper Person or Persons, and upon advice and statements of legal counsel
(including counsel for any Credit Party), independent accountants, and other
experts selected by the Agent. The Agent may deem and treat the payee of any
Note as the holder thereof for all purposes hereof unless and until the Agent
receives and accepts an Assignment and Acceptance executed in accordance with
Section 12.1 hereof. As to any matters not expressly provided for by this
Agreement, the Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the Required Lenders, and such instructions shall be binding on all of the
Lenders; provided, however, that the Agent shall not be required to take any
action that exposes the Agent to personal liability or that is contrary to any
Loan Document or applicable law or unless it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking any such action.

         11.3. Defaults. The Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default or Event of Default unless the Agent has
received written notice from a Lender or a Borrower specifying such Default or
Event of Default and stating that such notice is a "Notice of Default". In the
event that the Agent receives such a notice of the occurrence of a Default or
Event of Default, the Agent shall give prompt notice thereof to the Lenders. The
Agent shall (subject to Section 11.2 hereof) take such action with respect to
such Default or Event of Default as shall reasonably be directed by the Required
Lenders, provided that, unless and until the Agent shall have received such
directions, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lenders.

         11.4. Rights as Lender. With respect to its Revolving Credit Commitment
and the Loans made by it, Bank United (and any successor acting as Agent) in its
capacity as a Lender hereunder shall have the same rights and powers hereunder
as any other Lender and may exercise the same as though it were not acting as
the Agent, and the term "Lender" or "Lenders" shall, unless the context
otherwise indicates, include the Agent in its individual capacity. Bank United
(and any successor acting as Agent) and its affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, make
investments in, provide services to, and generally engage in any kind of
lending, trust, or other business with any Credit Party or any of its
Subsidiaries or affiliates as if it were not acting as Agent, and Bank United
(and any successor acting as Agent) and its affiliates may accept fees and other
consideration from any Credit Party or any of its Subsidiaries or affiliates for
services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

                                       83
<PAGE>   84
         11.5. Indemnification. The Lenders agree to indemnify the Agent (to the
extent not reimbursed under Section 8.13 or Section 12.9 hereof, but without
limiting the obligations of the Borrower under such Section) ratably in
accordance with their respective Revolving Credit Commitments, for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including attorneys' fees), or disbursements of any kind and
nature whatsoever that may be imposed on, incurred by or asserted against the
Agent (including by any Lender) in any way relating to or arising out of any
Loan Document or the transactions contemplated thereby or any action taken or
omitted by the Agent under any Loan Document (including any of the foregoing
arising from the negligence of the Agent); provided that no Lender shall be
liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified. Without
limitation of the foregoing, each Lender agrees to reimburse the Agent promptly
upon demand for its ratable share of any costs or expenses payable by the
Borrower under Section 12.5, to the extent that the Agent is not promptly
reimbursed for such costs and expenses by the Borrower. The agreements contained
in this Section 11.5 shall survive payment in full of the Loans and all other
amounts payable under this Agreement.

         11.6. Non-Reliance on Agent and Other Lenders. Each Lender agrees that
it has, independently and without reliance on the Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of the Credit Parties and their Subsidiaries and decision to
enter into this Agreement and that it will, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Loan Documents. Except for
notices, reports, and other documents and information expressly required to be
furnished to the Lenders by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition, or business of any
Credit Party or any of its Subsidiaries or affiliates that may come into the
possession of the Agent or any of its affiliates.

         11.7. Resignation of Agent. The Agent may resign at any time by giving
notice thereof to the Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Required Lenders 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 Lenders, appoint a successor Agent which shall be a commercial bank
organized under the laws of the United States of America having combined capital
and surplus of at least $500,000,000. Upon the acceptance of any appointment as
Agent hereunder by a successor, such successor shall thereupon succeed to and
become vested with all the rights, powers, discretion, privileges, and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations hereunder. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article XI 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.

                                       84
<PAGE>   85
         11.8. Sharing of Payments, etc. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, set-off, counterclaim or
otherwise, obtain payment with respect to its Obligations (other than pursuant
to Article V) which results in its receiving more than its pro rata share of the
aggregate payments with respect to all of the Obligations (other than any
payment expressly provided hereunder to be distributed on other than a pro rata
basis and payments pursuant to Article V), then (a) such Lender shall be deemed
to have simultaneously purchased from the other Lenders a share in their
Obligations so that the amount of the Obligations held by each of the Lenders
shall be pro rata and (b) such other adjustments shall be made from time to time
as shall be equitable to insure that the Lenders share such payments pro rata;
provided, however, that for purposes of this Section 11.8 the term "pro rata"
shall be determined with respect to the Revolving Credit Commitment of each
Lender and to the Total Revolving Credit Commitment after subtraction in each
case of amounts, if any, by which any such Lender has not funded its share of
the outstanding Loans and Obligations. If all or any portion of any such excess
payment is thereafter recovered from the Lender which received the same, the
purchase provided in this Section 11.8 shall be rescinded to the extent of such
recovery, without interest. Each Borrower expressly consents to the foregoing
arrangements and agrees that each Lender so purchasing a portion of the other
Lenders' Obligations may exercise all rights of payment (including, without
limitation, all rights of set-off, banker's lien or counterclaim) with respect
to such portion as fully as if such Lender were the direct holder of such
portion.

                                   ARTICLE XII

                                  Miscellaneous

         12.1. Assignments and Participations. (a) Each Lender may assign to one
or more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including, without limitation, all or a portion of its Loans,
its Note, and its Revolving Credit Commitment); provided, however, that

                  (i) each such assignment shall be to an Eligible Assignee;

                  (ii) except in the case of an assignment to another Lender or
an assignment of all of a Lender's rights and obligations under this Agreement,
any such partial assignment shall be in an amount at least equal to $5,000,000
or an integral multiple of $1,000,000 in excess thereof;

                  (iii) each such assignment by a Lender shall be of a constant,
and not varying, percentage of all of its rights and obligations under this
Agreement and the Note; and

                  (iv) the parties to such assignment shall execute and deliver
to the Agent for its acceptance an Assignment and Acceptance in the form of
Exhibit B hereto, together with any Note subject to such assignment and (except
in the case of assignments that increase the Maximum Available Amount) a
processing fee of $3,500.

Upon execution, delivery, and acceptance of such Assignment and Acceptance, the
assignee thereunder shall be a party hereto and, to the extent of such
assignment, have the obligations, rights, and benefits of a Lender hereunder and
the assigning Lender shall, to the extent of such assignment, relinquish its
rights and be released from its obligations under this Agreement. Upon the
consummation of any assignment pursuant to this Section, the assignor, the Agent
and the Borrowers shall make appropriate arrangements so that, if required, new
Notes are issued to the assignor and the assignee. If the assignee is not
incorporated under the laws of the United States of America or a state thereof,
it shall deliver to the Borrowers and the Agent certification as to exemption
from deduction or withholding of Taxes in accordance with Section 5.7.

         (b) The Agent shall maintain at its address referred to in Section 12.2
a copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the
Revolving Credit Commitment of, and principal amount of the Loans owing to, each
Lender from time to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Agent and the Lenders may treat each Person whose name is recorded
in the Register as a Lender hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                                       86
<PAGE>   87
         (c) Upon its receipt of an Assignment and Acceptance executed by the
parties thereto, together with any Note subject to such assignment and payment
of the processing fee (if required), the Agent shall, if such Assignment and
Acceptance has been completed and is in substantially the form of Exhibit B
hereto, (i) accept such Assignment and Acceptance, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
parties thereto.

         (d) Each Lender may sell participations to one or more Persons in all
or a portion of its rights, obligations or rights and obligations under this
Agreement (including all or a portion of its Revolving Credit Commitment or its
Loans); provided, however, that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) the participant shall be entitled to the benefit of the yield protection
provisions contained in Article V and the right of set-off contained in Section
12.3, and (iv) the Borrowers shall continue to deal solely and directly with
such Lender in connection with such Lender's rights and obligations under this
Agreement, and such Lender shall retain the sole right to enforce the
obligations of the Borrower relating to its Loans and its Note and to approve
any amendment, modification, or waiver of any provision of this Agreement (other
than amendments, modifications, or waivers decreasing the amount of principal of
or the rate at which interest is payable on such Loans or Note, extending any
scheduled principal payment date or date fixed for the payment of interest on
such Loans or Note, or extending its Revolving Credit Commitment).

         (e) Notwithstanding any other provision set forth in this Agreement,
any Lender may at any time assign and pledge all or any portion of its Loans and
its Note to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank. No
such assignment shall release the assigning Lender from its obligations
hereunder.

         (f) Any Lender may furnish any information concerning any Borrower or
any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants).

         (g) Whenever in this Agreement any of the parties hereto is referred
to, such reference shall be deemed to include the successors and permitted
assigns of such party and all covenants, provisions and agreements by or on
behalf of the Borrower which are contained in the Loan Documents shall inure to
the benefit of the successors and permitted assigns of the Agent, the Lenders,
or any of them. The Borrower may not assign or otherwise transfer to any other
Person any right, power, benefit, or privilege (or any interest therein)
conferred hereunder or under any of the other Loan Documents, or delegate (by
assumption or otherwise) to any other Person any duty, obligation, or liability
arising hereunder or under any of the other Loan Documents, and any such
purported assignment, delegation or other transfer shall be void.

         12.2. Notices. Any notice shall be conclusively deemed to have been
received by any party hereto and be effective (i) on the day on which delivered
(including hand delivery by commercial courier service) to such party (against
receipt therefor), (ii) on the date of transmission to such party, in the case
of notice by telegram, telefacsimile or telex (where the proper transmission of

                  (c)      if to the Lenders:

                           At the addresses set forth on the signature pages
                           hereof and on the signature page of each Assignment
                           and Acceptance.

         12.3. Right of Set-off; Adjustments. (a) Upon the occurrence and during
the continuance of any Event of Default, each Lender (and each of its
affiliates) is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender (or any of its affiliates)
to or for the credit or the account of any Borrower against any and all of the
obligations of such Borrower now or hereafter existing under this Agreement and
the Note held by such Lender, irrespective of whether such Lender shall have
made any demand under this Agreement or such Note and although such obligations
may be unmatured. Each Lender agrees promptly to notify such Borrower after any
such set-off and application made by such Lender; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 12.3 are in addition
to other rights and remedies (including, without limitation, other rights of
set-off) that such Lender may have.

         (b) If any Lender (a "benefitted Lender") shall at any time receive any
payment of all or part of the Loans owing to it, or interest thereon, or receive
any collateral in respect thereof (whether voluntarily or involuntarily, by
set-off, or otherwise), in a greater proportion than any such payment to or
collateral received by any other Lender, if any, in respect of such other
Lender's Loans owing to it, or interest thereon, such benefitted Lender shall
purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Loans owing to it, or shall provide such
other Lenders with the benefits of any such collateral, or the proceeds thereof,
as shall be necessary to cause such benefitted Lender to share the excess
payment or benefits of such collateral or proceeds ratably with each of the
Lenders; provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest. The Borrowers agrees that any Lender so
purchasing a participation from a Lender pursuant to this Section 12.3 may, to
the fullest extent permitted by law, exercise all of its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Person were the direct creditor of the Borrower in the amount of such
participation.

         12.4. Survival. All covenants, agreements, representations and
warranties made herein shall survive the making by the Lenders of the Loans and
the execution and delivery to the Lenders of this Agreement and the Notes and
shall continue in full force and effect so long as any of Obligations remain
outstanding or any Lender has any LIBOR Rate Loan hereunder or any Borrower has
continuing obligations hereunder unless otherwise provided herein.

                                       90
<PAGE>   91
         12.5. Expenses. The Borrowers agree to pay on demand all reasonable
costs and expenses of the Agent in connection with the syndication, preparation,
execution, delivery, administration, modification, and amendment of this
Agreement, the other Loan Documents, and the other documents to be delivered
hereunder, including, without limitation, the reasonable fees and expenses of
counsel for the Agent with respect thereto and with respect to advising the
Agent as to its rights and responsibilities under the Loan Documents. The
Borrowers further agree to pay on demand all reasonable costs and expenses of
the Agent and the Lenders, if any (including, without limitation, reasonable
attorneys' fees and expenses), in connection with the enforcement (whether
through negotiations, legal proceedings, or otherwise) of the Loan Documents and
the other documents to be delivered hereunder.

         12.6. Amendments and Waivers. Any provision of this Agreement or any
other Loan Document may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by the Borrowers (or, as to Loan Documents
other than the Credit Agreement, the Credit Party party to such Loan Document)
and the Required Lenders, or the Agent on behalf of the Required Lenders (and,
if Article XI or the rights or duties of the Agent are affected thereby, by the
Agent); provided that no such amendment or waiver shall, unless signed by all
the Lenders, (i) increase the Revolving Credit Commitment of the Lenders, (ii)
reduce the principal of or rate of interest on any Loan or any fees or other
amounts payable hereunder, (iii) postpone any date fixed for the payment of any
scheduled installment of principal of or interest on any Loan or any fees or
other amounts payable hereunder or for termination of any Revolving Credit
Commitment, or (iv) change the percentage of the Revolving Credit Commitment or
of the unpaid principal amount of the Notes, or the number of Lenders, which
shall be required for the Lenders or any of them to take any action under this
Section 12.6 or any other provision of this Agreement or (v) release all or
substantially all of the Collateral.

         No notice to or demand on any Borrower in any case shall entitle any
Borrower to any other or further notice or demand in similar or other
circumstances, except as otherwise expressly provided herein. No delay or
omission on any Lender's or the Agent's part in exercising any right, remedy or
option shall operate as a waiver of such or any other right, remedy or option or
of any Default or Event of Default.

         12.7. Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, and it shall not be necessary in making proof of this Agreement to
produce or account for more than one such fully-executed counterpart.

         12.8. Termination. The termination of this Agreement shall not affect
any rights of the Borrowers, the Lenders or the Agent or any obligation of the
Borrowers, the Lenders or the Agent, arising prior to the effective date of such
termination, and the provisions hereof shall continue to be fully operative
until all transactions entered into or rights created or obligations incurred
prior to such termination have been fully disposed of, concluded or liquidated
and the Obligations arising prior to or after such termination have been
irrevocably paid in full. The rights granted to the Agent for the benefit of the
Lenders under the Loan Documents shall continue in full force and effect,
notwithstanding the termination of this Agreement, until all of the Obligations
have been paid in full after the termination hereof (other than Obligations in
the nature of continuing indemnities or expense reimbursement obligations not
yet due and payable, which shall continue) or the Borrowers have furnished the
Lenders and the Agent with an indemnification satisfactory to the Agent and each
Lender with respect thereto. All representations, warranties, covenants, waivers
and agreements contained herein shall survive termination hereof until payment
in full of the Obligations unless otherwise provided herein. Notwithstanding the
foregoing, if after receipt of any payment of all or any part of the
Obligations, any Lender is for any reason compelled to surrender such payment to
any Person because such payment is determined to be void or voidable as a
preference, impermissible setoff, a diversion of trust funds or for any other
reason, this Agreement shall continue in full force and the Borrowers shall be
liable to, and shall indemnify and hold the Agent or such Lender harmless for,
the amount of such payment surrendered until the Agent or such Lender shall have
been finally and irrevocably paid in full. The provisions of the foregoing
sentence shall be and remain effective notwithstanding any contrary action which
may have been taken by the Agent or the Lenders in reliance upon such payment,
and any such contrary action so taken shall be without prejudice to the Agent or
the Lenders' rights under this Agreement and shall be deemed to have been
conditioned upon such payment having become final and irrevocable.

         12.9. INDEMNIFICATION; LIMITATION OF LIABILITY. (A) THE BORROWERS,
INDIVIDUALLY AND COLLECTIVELY, AGREE TO INDEMNIFY AND HOLD HARMLESS THE AGENT
AND EACH LENDER AND EACH OF THEIR AFFILIATES AND THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM
AND AGAINST ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES, COSTS, AND
EXPENSES (INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES) THAT MAY BE
INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE
ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF (INCLUDING, WITHOUT
LIMITATION, IN CONNECTION WITH ANY INVESTIGATION, LITIGATION, OR PROCEEDING OR
PREPARATION OF DEFENSE IN CONNECTION THEREWITH) THE LOAN DOCUMENTS, ANY OF THE
TRANSACTIONS CONTEMPLATED HEREIN, THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF
THE LOANS, ANY PROJECT, ANY OPERATOR, ANY PROJECT DOCUMENT OR ANY OTHER DOCUMENT
OR OCCURRENCE RELATING TO ANY PROJECT OR TO THE BUSINESS OF ANY BORROWER
(INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED
PARTY), EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR
EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT
JURISDICTION TO HAVE RESULTED FROM SUCH INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT. IN THE CASE OF AN INVESTIGATION, LITIGATION OR OTHER
PROCEEDING TO WHICH THE INDEMNITY IN THIS SECTION 12.9 APPLIES, SUCH INDEMNITY
SHALL BE EFFECTIVE WHETHER OR NOT SUCH INVESTIGATION, LITIGATION OR PROCEEDING
IS BROUGHT BY THE BORROWER, ITS DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN
INDEMNIFIED PARTY OR ANY OTHER PERSON OR ANY INDEMNIFIED PARTY IS OTHERWISE A
PARTY THERETO AND WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE
CONSUMMATED. EACH BORROWER AGREES THAT NO INDEMNIFIED PARTY SHALL HAVE ANY
LIABILITY (WHETHER DIRECT OR INDIRECT, IN CONTRACT OR TORT OR OTHERWISE) TO IT,
ANY OF ITS SUBSIDIARIES, OR ANY SECURITY HOLDERS OR CREDITORS THEREOF ARISING
OUT OF, RELATED TO OR IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREIN,
EXCEPT TO THE EXTENT THAT SUCH LIABILITY IS FOUND IN A FINAL NON-APPEALABLE
JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE DIRECTLY RESULTED FROM
SUCH INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. EACH BORROWER
AGREES NOT TO ASSERT ANY CLAIM AGAINST THE AGENT, ANY LENDER, ANY OF THEIR
AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES,
ATTORNEYS, AGENTS, AND ADVISERS, ON ANY THEORY OF LIABILITY, FOR SPECIAL,
INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE
RELATING TO THE LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR
THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE LOANS.

         (B) WITHOUT PREJUDICE TO THE SURVIVAL OF ANY OTHER AGREEMENT OF THE
BORROWER HEREUNDER, THE AGREEMENTS AND OBLIGATIONS OF THE BORROWER CONTAINED IN
THIS SECTION 12.9 SHALL SURVIVE THE PAYMENT IN

                                       93
<PAGE>   94
FULL OF THE LOANS AND ALL OTHER AMOUNTS PAYABLE UNDER THIS AGREEMENT.

         12.10. Severability. If any provision of this Agreement or the other
Loan Documents shall be determined to be illegal or invalid as to one or more of
the parties hereto, then such provision shall remain in effect with respect to
all parties, if any, as to whom such provision is neither illegal nor invalid,
and in any event all other provisions hereof shall remain effective and binding
on the parties hereto.

         12.11. ENTIRE AGREEMENT. THIS AGREEMENT, TOGETHER WITH THE OTHER LOAN
DOCUMENTS, CONSTITUTES THE ENTIRE AGREEMENT AMONG THE PARTIES WITH RESPECT TO
THE SUBJECT MATTER HEREOF AND SUPERSEDES ALL PREVIOUS PROPOSALS, NEGOTIATIONS,
REPRESENTATIONS, LIBOR RATE LOANS AND OTHER COMMUNICATIONS BETWEEN OR AMONG THE
PARTIES, BOTH ORAL AND WRITTEN, WITH RESPECT THERETO.

         12.12. Agreement Controls. In the event that any term of any of the
Loan Documents other than this Agreement conflicts with any express term of this
Agreement, the terms and provisions of this Agreement shall control to the
extent of such conflict.

                                       94
<PAGE>   95
         12.13. Usury Savings Clause. Notwithstanding any other provision
herein, the aggregate interest rate charged under any of the Notes, including
all charges or fees in connection therewith deemed in the nature of interest
under applicable law shall not exceed the Highest Lawful Rate (as such term is
defined below). If the rate of interest (determined without regard to the
preceding sentence) under this Agreement at any time exceeds the Highest Lawful
Rate (as defined below), the outstanding amount of the Loans made hereunder
shall bear interest at the Highest Lawful Rate until the total amount of
interest due hereunder equals the amount of interest which would have been due
hereunder if the stated rates of interest set forth in this Agreement had at all
times been in effect. In addition, if when the Loans made hereunder are repaid
in full the total interest due hereunder (taking into account the increase
provided for above) is less than the total amount of interest which would have
been due hereunder if the stated rates of interest set forth in this Agreement
had at all times been in effect, then to the extent permitted by law, the
Borrowers shall pay to the Agent an amount equal to the difference between the
amount of interest paid and the amount of interest which would have been paid if
the Highest Lawful Rate had at all times been in effect. Notwithstanding the
foregoing, it is the intention of the Lenders and the Borrowers to conform
strictly to any applicable usury laws. Accordingly, if any Lender contracts for,
charges, or receives any consideration which constitutes interest in excess of
the Highest Lawful Rate, then any such excess shall be cancelled automatically
and, if previously paid, shall at such Lender's option be applied to the
outstanding amount of the Loans made hereunder or be refunded to the Borrowers.
As used in this paragraph, the term "Highest Lawful Rate" means the maximum
lawful interest rate, if any, that at any time or from time to time may be
contracted for, charged, or received under the laws applicable to such Lender
which are presently in effect or, to the extent allowed by law, under such
applicable laws which may hereafter be in effect and which allow a higher
maximum nonusurious interest rate than applicable laws now allow.

         12.14. Payments. All principal, interest, and other amounts to be paid
by the Borrowers under this Agreement and the other Loan Documents shall be paid
to the Agent at the Principal Office in Dollars and in immediately available
funds, without setoff, deduction or counterclaim. Subject to the definition of
"Interest Period" herein, whenever any payment under this Agreement or any other
Loan Document shall be stated to be due on a day that is not a Business Day,
such payment may be made on the next succeeding Business Day, and such extension
of time in such case shall be included in the computation of interest and fees,
as applicable, and as the case may be.

         12.15. GOVERNING LAW; WAIVER OF JURY TRIAL.

                  (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN
         THOSE SECURITY INSTRUMENTS WHICH EXPRESSLY PROVIDE THAT THEY SHALL BE
         GOVERNED BY THE LAWS OF ANOTHER JURISDICTION) SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS APPLICABLE
         TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

                                       95
<PAGE>   96
                  (b) THE BORROWERS HEREBY EXPRESSLY AND IRREVOCABLY AGREE AND
         CONSENT THAT ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING
         TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREIN MAY BE
         INSTITUTED IN ANY STATE OR FEDERAL COURT SITTING IN THE COUNTY OF
         HARRIS, STATE OF TEXAS, UNITED STATES OF AMERICA AND, BY THE EXECUTION
         AND DELIVERY OF THIS AGREEMENT, EACH BORROWER EXPRESSLY WAIVES ANY
         OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE IN,
         OR TO THE EXERCISE OF JURISDICTION OVER IT AND ITS PROPERTY BY, ANY
         SUCH COURT IN ANY SUCH SUIT, ACTION OR PROCEEDING, AND EACH BORROWER
         HEREBY IRREVOCABLY SUBMITS GENERALLY AND UNCONDITIONALLY TO THE
         JURISDICTION OF ANY SUCH COURT IN ANY SUCH SUIT, ACTION OR PROCEEDING.

                  (c) THE BORROWERS AGREE THAT SERVICE OF PROCESS MAY BE MADE BY
         PERSONAL SERVICE OF A COPY OF THE SUMMONS AND COMPLAINT OR OTHER LEGAL
         PROCESS IN ANY SUCH SUIT, ACTION OR PROCEEDING, OR BY REGISTERED OR
         CERTIFIED MAIL (POSTAGE PREPAID) TO THE ADDRESS OF THE BORROWER
         PROVIDED IN SECTION 12.2, OR BY ANY OTHER METHOD OF SERVICE PROVIDED
         FOR UNDER THE APPLICABLE LAWS IN EFFECT IN THE STATE OF TEXAS.

                  (d) NOTHING CONTAINED IN SUBSECTIONS (a) OR (b) HEREOF SHALL
         PRECLUDE THE AGENT OR ANY LENDER FROM BRINGING ANY SUIT, ACTION OR
         PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT IN THE
         COURTS OF ANY JURISDICTION WHERE ANY BORROWER OR ANY BORROWER'S
         PROPERTY OR ASSETS MAY BE FOUND OR LOCATED. TO THE EXTENT PERMITTED BY
         THE APPLICABLE LAWS OF ANY SUCH JURISDICTION, EACH BORROWER HEREBY
         IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY SUCH COURT AND EXPRESSLY
         WAIVES, IN RESPECT OF ANY SUCH SUIT, ACTION OR PROCEEDING, OBJECTION TO
         THE EXERCISE OF JURISDICTION OVER IT AND ITS PROPERTY BY ANY SUCH OTHER
         COURT OR COURTS WHICH NOW OR HEREAFTER MAY BE AVAILABLE UNDER
         APPLICABLE LAW.

                  (e) IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY
         RIGHTS OR REMEDIES UNDER OR RELATED TO ANY LOAN DOCUMENT OR ANY
         AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR THAT MAY IN
         THE FUTURE BE DELIVERED IN CONNECTION THEREWITH, THE BORROWERS, THE
         AGENT AND THE LENDERS HEREBY AGREE, TO THE EXTENT PERMITTED BY
         APPLICABLE LAW, THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED
         BEFORE A COURT AND NOT BEFORE A JURY AND HEREBY IRREVOCABLY WAIVE, TO
         THE EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH

                                       96

     Section 2.1 The Original Loan Agreement is hereby amended as follows:

     (a) The definition of "Alternate Applicable Margin" appearing in Article 1
is deleted in its entirety and the following is substituted therefor:

          "Alternate Applicable Margin" - as at any date of determination, with
     respect to LIBOR Loans, the applicable percentage set forth below based
     upon the Ratings in effect on such date:

     Both of the following Ratings:

              Baa2 or higher by Moody's                            .875%

     At least two of the following Ratings:
              BBB- by S&P
              Baa3 by Moody's
              BBB- by D&P                                         1.000%

     Any one of the following Ratings:
              BBB- by S&P; or
              Baa3 by Moody's; or
              BBB- by D&P                                         1.125%

     by S&P or Moody's or D&P                                     1.500%

     If any Rating shall be changed (other than as a result of a change in the
     rating system of the applicable Rating Agency) , such change shall be
     effective as of the date on which it is first announced by the Rating
     Agency making such change. Each such change in the Alternate Applicable
     Margin shall apply to all outstanding LIBOR Loans during the period
     commencing on the effective date of such change and ending on the date
     immediately preceding the effective date of the next such change. If the
     rating system of any Rating Agency shall change, the parties hereto shall
     negotiate in good faith to amend the references to specific ratings in this
     definition to reflect such changed rating system."

     (b) The definition of "Commitment Fee Percentage" appearing in Article 1 is
amended by deleting the last paragraph thereof and substituting therefor the
following:

     Applicable Margin becomes effective and

                                       3

     continuing at all times thereafter, the Commitment Fee Percentage shall be
     based upon the Ratings in effect on such date, as follows:

     Both of the following Ratings:
              BBB or higher by S&P; and
              Baa2 or higher by Moody's                           .200%

     At least two of the following Ratings:

              Baa3 by Moody's
              BBB- by D&P                                         1.250%

     Any one of the following Ratings:
              BBB- by S&P; or
              Baa3 by Moody's; or
              BBB-by D&P                                          .300%

     by S&P or Moody's or D&P                                     .375%

     If any Rating shall be changed (other than as a result of a change in the
     rating system of the applicable Rating Agency), such change shall be
     effective as of the date on which it is first announced by the Rating
     Agency making such change. Each such change with respect to the Borrowers
     shall apply at any time during the period commencing on the effective date
     of such change and ending on the date immediately preceding the effective
     date of the next such change. If the rating system of any Rating Agency
     shall change, the parties hereto shall negotiate in good faith to amend the
     references to specific ratings in this definition to reflect such changed
     rating system."

     (c) The phrase "the aggregate amount set forth opposite such Bank's name on
the signature pages hereof" appearing in the definition of the term "Revolving
Credit Commitment" in Article 1 of the Original Loan Agreement shall be deemed
to refer to the amounts set forth opposite each Bank's name on the signature
pages hereto.

appearing in Article 1 is amended by deleting the date "March 28, 200011 and
substituting therefor the date "March 28, 2001".

deleted in its entirety and the following is substituted therefor:

     grid based on such Rating as set forth in the definition of Alternate
     Applicable Margin in Article 1 hereof with respect to LIBOR

     Loans. In order to elect the Alternate Applicable Margin, the Borrowers
     shall give prior written notice to the Agent of the receipt of the Ratings
     (together with written evidence thereof), which election may be made only
     one time during the Credit Period. The Alternate Applicable Margin shall
     become effective upon receipt of such notice by the Agent and shall
     continue in effect at all times thereafter."

     (f) Section 7.15 (Construction Investments) shall be redesignated as
Section 7.16 and shall be amended and restated in its entirety to read as
follows:

               "Section 7.16 Construction Investments.
