         WHEREAS, the Borrowers, the Banks and Bank of America, N.A., as agent
for the Banks, are parties to the Existing Credit Agreement, which provided for

         WHEREAS, by means of a letter agreement dated August 24, 2001, each of

                                   THE CREDITS

         2.1 Amounts and Terms of Commitments. Each Bank severally agrees, on
the terms and conditions set forth herein, to make Loans to the Borrowers from
time to time on any Business Day during the period from the Refinancing Date to
the Commitment Termination Date equal to its Pro Rata Share of the aggregate
amount of the Borrowing requested by a Borrower to


                                       2


be made on such day. The Commitment of each Bank and the outstanding principal
amount of Loans made by each Bank hereunder shall not exceed at any time the
aggregate amount set forth on Schedule II (such amount as the same may be
reduced under Section 2.5 or as a result of one or more assignments as permitted
herein pursuant to Section 3.7 and Section 9.7, the Bank's "Commitment");
provided, however, that, after giving effect to any Borrowing, the aggregate
principal amount of all outstanding Loans shall not at any time exceed the
Commitment Amount; and provided, further, that the aggregate principal amount of
all Loans outstanding from time to time to a Borrower shall not exceed the
Borrowing Base for the relevant Borrower. Within the limits of each Bank's
Commitment, and subject to the other terms and conditions hereof, a Borrower may
borrow under this Section 2.1, repay under the terms hereof and reborrow under
this Section 2.1.

         2.2 Notes. The Loans made by each Bank under its Commitment to a
Borrower shall be evidenced by a Note in the form of Exhibit 2.2. Each such Bank
shall record on the schedules annexed to its Note the date, amount and maturity
of each Loan made by it and the amount of each payment of principal made by the
relevant Borrower with respect thereto. Each such Bank is irrevocably authorized
by each Borrower to so record such information on such schedules to its Note,
and each Bank's record shall be rebuttable presumptive evidence; provided,
however, that the failure of a Bank to make, or an error in making, a notation
thereon with respect to any Loan shall not limit or otherwise affect the
obligations of the relevant Borrower hereunder or under any such Note to such
Bank.

         2.3 Procedure for Borrowing.

                  (a) Each Borrowing shall be made upon a Borrower's irrevocable
         written notice or telephonic notice confirmed in writing within 24
         hours delivered to the Agent in the form of a loan request ("Loan
         Request") substantially in the form of Exhibit 2.3 hereto (which notice
         must be received on a Business Day by the Agent prior to 12:00 noon
         (Eastern time)) (i) three Business Days prior to the requested
         Borrowing Date, in the case of Offshore Rate Loans, and (ii) on the
         Borrowing Date for which a Loan is requested, in the case of Federal
         Funds Rate Loans, specifying:

                           (A) the amount of the Borrowing, which shall be in an
                  aggregate minimum amount of $1,000,000 or any multiple of
                  $1,000,000 in excess thereof;

                           (B) the requested Borrowing Date, which shall be a
                  Business Day;

                           (C) the Type of Loans comprising the Borrowing; and

                           (D) the duration of the Interest Period applicable to
                  such Loans included in such notice. If the Loan Request fails
                  to specify the duration of the Interest Period for any
                  Borrowing comprised of Offshore Rate Loans, such Interest
                  Period shall be two weeks.

         In the event that more than one Loan Request is delivered on any
Business Day, the Agent shall, for purposes of ensuring that the aggregate of
the then-outstanding Loans and the


                                       3

Loans which are the subject of the Loan Requests will not exceed the Commitment
Amount, process the Loan Requests in the order of receipt.

                  (b) The Agent will promptly notify each Bank of its receipt of
         any Loan Request and of the amount of such Bank's Pro Rata Share of
         that Borrowing.

                  (c) Each Bank will make the amount of its Pro Rata Share of
         each Borrowing available to the Agent for the account of the Borrower
         at the Agent's Payment Office by 2:00 p.m. (Eastern time) on the
         Borrowing Date requested by a Borrower in funds immediately available
         to the Agent for deposit to the account which the Agent shall from time
         to time specify by notice to the Banks. The proceeds of all such Loans
         will then be made available promptly to the relevant Borrower by the
         Agent in accordance with written instructions provided to the Agent by
         the Borrower in like funds as received by the Agent. No Bank's
         obligation to make any Loan shall be affected by any other Bank's
         failure to make any Loan.

                  (d) After giving effect to any Borrowing, there may not be
         more than three (3) different Interest Periods in effect with respect
         to each Borrower.

         2.4 Conversion and Continuation Elections.

                  (a) A Borrower may, as to its Loans, upon irrevocable written
         notice or telephonic notice confirmed in writing within 24 hours to the
         Agent in accordance with Section 2.4(b):

                           (i) elect, as of any Business Day, in the case of
                  Federal Funds Rate Loans, or as of the last day of the
                  applicable Interest Period, in the case of any other Type of
                  Loans (other than a Swing Loan), to convert any such Loans (or
                  any part thereof in an amount that is not less than $1,000,000
                  or an integral multiple of $1,000,000 in excess thereof) into
                  Loans of any other Type; or

                           (ii) elect, as of the last day of the applicable
                  Interest Period, to continue any Loans having Interest Periods
                  expiring on such day (or any part thereof in an amount that is
                  not less than $1,000,000 or an integral multiple of $1,000,000
                  in excess thereof);

         provided that, if at any time the aggregate amount of Offshore Rate
         Loans in respect of any Borrowing is reduced by payment, prepayment or
         conversion of part thereof to be less than $1,000,000, such Offshore
         Rate Loans shall automatically convert into Federal Funds Rate Loans,
         and on and after such date, the right of the Borrower to continue such
         Loans as, and convert such Loans into, Offshore Rate Loans shall
         terminate.

         Notwithstanding anything to the contrary, no Loan shall be outstanding
         for a period of more than sixty (60) days (including, in the case of a
         Loan that was initially made as a Swing Loan, the days during which
         such Loan was a Swing Loan) and there shall be no more than three
         Interest Periods in respect of an Offshore Rate Loan with respect to
         each Borrower.


                                       4

                  (b) The relevant Borrower shall deliver a
         Conversion/Continuation Notice as to its Loans to be received by the
         Agent not later than 12:00 noon (Eastern time) at least (i) three
         Business Days in advance of the Conversion/Continuation Date, if the
         Loans are to be converted into or continued as Offshore Rate Loans, and
         (ii) on the Conversion/Continuation Date, if the Loans are to be
         continued or converted into Federal Funds Rate Loans, specifying:

                           (A) the proposed Conversion/Continuation Date;

                           (B) the aggregate amount of Loans to be converted or
                  continued;

                           (C) the Type of Loans resulting from the proposed
                  conversion or continuation; and

                           (D) other than in the case of conversions into
                  Federal Funds Rate Loans, the duration of the requested
                  Interest Period.

                  (c) The Agent will promptly notify each Bank of its receipt of
         a Conversion/Continuation Notice. All conversions and continuations
         shall be made ratably according to the respective outstanding principal
         amounts of the Loans with respect to which the notice was given held by
         each Bank.

                  (d) Unless the Majority Banks otherwise agree, during the
         existence of a Default with respect to a Borrower, such Borrower may
         not elect to have a Loan converted into or continued as an Offshore
         Rate Loan.

         2.5 Voluntary Termination or Reduction of Commitments. The Borrowers
may, upon not less than five Business Days' prior written or telephonic notice
to the Agent, terminate the Commitments, or permanently reduce the Commitments
by an aggregate minimum amount of $5,000,000 or any multiple of $1,000,000 in
excess thereof; unless, after giving effect thereto and to any prepayments of
Loans made on the effective date thereof, the then-outstanding principal amount
of the Loans would exceed the amount of the Commitment Amount then in effect.
Once reduced in accordance with this Section, the Commitment Amount may not be
increased. Any reduction of the Commitment Amount shall be applied to each Bank
according to its Pro Rata Share. All accrued commitment fees to but not
including the effective date of any termination of Commitments shall be paid on
the effective date of such termination. All accrued commitment fees to but not
including the effective date of any reduction of Commitments shall be paid on
the last Business Day of the then-current calendar quarter.

         2.6 Prepayments.

                  (a) If at any time the outstanding balance of a Borrower's
         Indebtedness shall exceed the then-current Borrowing Base of such
         Borrower and at such time as there are Loans outstanding to such
         Borrower, such Borrower shall immediately prepay the outstanding
         principal amount of its Loans in an amount equal to such excess,
         together with interest accrued thereon and amounts required under
         Section 3.4.


                                       5


                  (b) Subject to Section 3.4, a Borrower may, at any time or
         from time to time, upon not less than three Business Days' irrevocable
         written or telephonic notice to the Agent, ratably prepay its Loans, in
         whole or in part, in minimum amounts of $1,000,000 or any multiple of
         $1,000,000 in excess thereof. Such notice of prepayment shall specify
         the date and amount of such prepayment and the Type(s) of Loans to be
         prepaid. If such notice is given, the relevant Borrower shall make such
         prepayment to the Agent, and the payment amount specified in such
         notice shall be due and payable on the date specified therein, together
         with, in the case of the prepayment of Offshore Rate Loans, accrued
         interest to each such date on the amount prepaid and any amounts
         required pursuant to Section 3.4.

                  (c) The Agent will promptly notify each Bank of its receipt of
         any such notice and of such Bank's Pro Rata Share of such prepayment.

                  (d) Each prepayment of any Loans pursuant to this Section
         shall be without premium or penalty, except as may be required by
         Section 3.4. No voluntary prepayment of principal of any Loans shall
         cause a reduction in the Commitment Amount.

         2.7 Repayment. Each Borrower shall repay to the Agent for the benefit
of the Banks on the Commitment Termination Date the aggregate principal amount
of its Loans outstanding on such date.

         2.8 Interest.

                  (a) Each Loan shall bear interest on the outstanding principal
         amount thereof from the applicable Borrowing Date at a rate per annum
         equal to the Federal Funds Rate or the Offshore Rate, as the case may
         be (and subject to a Borrower's right to convert to another Type of
         Loans under Section 2.4), plus the Applicable Margin.

                  (b) Interest on each Loan shall be paid by the relevant
         Borrower on its Loans in arrears on each Interest Payment Date.
         Interest shall also be paid by the relevant Borrower on its Loans on
         the date of any prepayment of Offshore Rate Loans under Section 2.6 for
         the portion of such Loans so prepaid and upon payment (including
         prepayment) in full thereof, and during the existence of any Event of
         Default, interest from the Borrower subject to such Event of Default
         shall be paid by such Borrower on demand of the Agent at the request or
         with the consent of the Majority Banks.

         Notwithstanding subsection (a) of this Section, if any amount of
         principal of or interest on any Loan, or any other amount payable
         hereunder or under any other Credit Document, is not paid in full when
         due by the relevant Borrower on its Loans (whether at stated maturity
         or by acceleration, demand or otherwise), the relevant Borrower agrees,
         to the extent permitted by law, to pay interest on such unpaid
         principal or other amount from the date such amount becomes due until
         the date such amount is paid in full, and after as well as before any
         entry of judgment thereon, payable on demand at a fluctuating rate per
         annum equal to the Base Rate plus 2%.

                  (c) Anything herein to the contrary notwithstanding, the
         obligations of each Borrower to any Bank hereunder shall be subject to
         the limitation that payments of


                                       6

         interest shall not be required for any period for which interest is
         computed hereunder, to the extent (but only to the extent) that
         contracting for or receiving such payment by such Bank would be
         contrary to the provisions of any law applicable to such Bank limiting
         the highest rate of interest that may be lawfully contracted for,
         charged or received by such Bank, and in such event the relevant
         Borrower shall pay such Bank interest at the highest rate permitted by
         applicable law.

         2.9 Fees.

                  (a) Arrangement, Agency Fees. The Borrowers shall pay on a
         several, and not on a joint, basis an arrangement fee to the Arranger
         for the Arranger's own account, and shall pay agency fees to the Agent
         for the Agent's own account, as required by the letter agreement ("Fee
         Letter") among the Borrowers, the Arranger and the Agent dated August
         16, 2000. Van Kampen Prime Rate Income Trust shall be responsible for
         its pro rata portion of such fees and Van Kampen Senior Floating Rate
         Fund shall be responsible for its pro rata portion of such fees based
         upon the relative net asset value of each Borrower on any date of
         determination thereof.

                  (b) Commitment Fees. The Borrowers shall pay on a several, and
         not on a joint, basis to the Agent for the account of each Bank a
         commitment fee on the daily unused portion of such Bank's Commitment,
         computed on a quarterly basis in arrears on the last Business Day of
         each calendar quarter based upon the daily utilization for that quarter
         as calculated by the Agent, equal to 0.11% per annum. For the avoidance
         of doubt, the contingent obligation of a Bank to pay funds to BofA in
         respect of a Swing Loan that may convert to a Federal Funds Rate Loan
         as provided in Section 2.16 shall not be considered use of such
         Borrower's Commitment. Van Kampen Prime Rate Income Trust shall be
         responsible for its pro rata portion of the commitment fee and Van
         Kampen Senior Floating Rate Fund shall be responsible for its pro rata
         portion of the commitment fee based upon the relative net asset value
         of each Borrower on any date of determination thereof. Such commitment
         fee shall accrue from the date of this fourth amended and restated
         Agreement to the Commitment Termination Date and shall be due and
         payable quarterly in arrears on the last Business Day of each March,
         June, September and December commencing on November 9, 2001 through the
         Commitment Termination Date, with the final payment to be made on the
         Commitment Termination Date. All accrued commitment fees to but not
         including the effective date of any termination of Commitments shall be
         paid on the effective date of such termination. All accrued commitment
         fees to but not including the effective date of any reduction of
         Commitments shall be paid on the last Business Day of the then-current
         calendar quarter, with such quarterly payment being calculated on the
         basis of the period from such reduction date to such quarterly payment
         date. The commitment fees provided in this subsection shall accrue at
         all times after the above-mentioned commencement date, including at any
         time during which one or more conditions in Article IV are not met.

         2.10 Computation of Fees and Interest.

                  (a) All computations of interest on the basis of the Base Rate
         shall be made on the basis of a year of 365 or 366 days, as the case
         may be, and actual days elapsed. All


                                       7

         other computations of fees and interest shall be made on the basis of a
         360-day year and actual days elapsed (which results in more interest
         being paid than if computed on the basis of a 365- or 366-day year).
         Interest and fees shall accrue during each period during which interest
         or such fees are computed from the first day thereof to the last day
         thereof.

                  (b) Each determination of an interest rate by the Agent shall
         be conclusive and binding on the Borrower and the Banks in the absence
         of manifest error. The Agent will, at the request of a Borrower or any
         Bank, deliver to such Borrower or Bank, as the case may be, a statement
         showing the quotations used by the Agent in determining any interest
         rate and the resulting interest rate.

         2.11 Payments.

                  (a) All payments to be made by a Borrower shall be made
         without set-off, recoupment or counterclaim, subject to Section 3.1.
         Except as otherwise expressly provided herein, all such payments shall
         be made to the Agent for the account of the Banks at the Agent's
         Payment Office and shall be made in Dollars and in immediately
         available funds no later than 2:00 p.m. (Eastern time) on the date
         specified herein. The Agent will promptly distribute to each Bank its
         Pro Rata Share (or other applicable share as expressly provided herein)
         of such payment in like funds as received. Any payment received by the
         Agent later than 2:00 p.m. (Eastern time) shall be deemed to have been
         received on the following Business Day, and any applicable interest or
         fee shall continue to accrue.

                  (b) Subject to the provisions set forth in the definition of
         "Interest Period" herein, whenever any payment is due on a day other
         than a Business Day, such payment shall be made on the following
         Business Day, and such extension of time shall in such case be included
         in the computation of interest or fees, as the case may be.

                  (c) Unless the Agent receives notice from a Borrower prior to
         the date on which any payment is due to the Banks that such Borrower
         will not make such payment in full as and when required, the Agent may
         assume that such Borrower has made such payment in full to the Agent on
         such date in immediately available funds, and the Agent may (but shall
         not be so required), in reliance upon such assumption, distribute to
         each Bank on such due date an amount equal to the amount then due such
         Bank. If and to the extent a Borrower has not made such payment in full
         to the Agent, each Bank shall repay to the Agent on demand such amount
         distributed to such Bank, together with interest thereon at the Federal
         Funds Rate for each day from the date such amount is distributed to
         such Bank until the date repaid.

         2.12 Payments by the Banks to the Agent.

                  (a) Unless the Agent receives notice from a Bank on or prior
         to the Closing Date or, with respect to any Borrowing after the Closing
         Date, at least one Business Day prior to the date of such Borrowing,
         that such Bank will not make available as and when required hereunder
         to the Agent for the account of a Borrower the amount of that Bank's
         Pro Rata Share of the Borrowing, the Agent may assume that each Bank
         has made such


                                       8

         amount available to the Agent in immediately available funds on the
         Borrowing Date and the Agent may (but shall not be so required), in
         reliance upon such assumption, make available to the relevant Borrower
         on such date a corresponding amount. If and to the extent any Bank
         shall not have made its full amount available to the Agent in
         immediately available funds and the Agent in such circumstances has
         made available to the relevant Borrower such amount, that Bank shall on
         the Business Day following such Borrowing Date make such amount
         available to the Agent, together with interest at the Federal Funds
         Rate for each day during such period. A notice of the Agent submitted
         to any Bank with respect to amounts owing under this subsection (a)
         shall be conclusive, absent manifest error. If such amount is so made
         available, such payment to the Agent shall constitute such Bank's Loan
         on the date of Borrowing for all purposes of this Agreement. If such
         amount is not made available to the Agent on the Business Day following
         the Borrowing Date, the Agent will notify the relevant Borrower of such
         failure to fund, and upon demand by the Agent, such Borrower shall pay
         such amount to the Agent for the Agent's account, together with
         interest thereon for each day elapsed since the date of such Borrowing,
         at a rate per annum equal to the interest rate applicable at the time
         to the Loans comprising such Borrowing.

                  (b) The failure of any Bank to make any Loan on any Borrowing
         Date shall not relieve any other Bank of any obligation hereunder to
         make a Loan on such Borrowing Date, but no Bank shall be responsible
         for the failure of any other Bank to make the Loan to be made by such
         other Bank on any Borrowing Date.

         2.13 Sharing of Payments, etc. If, other than as expressly provided
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off or otherwise) in excess of its Pro Rata Share, such Bank shall
immediately (a) notify the Agent of such fact and (b) purchase from the other
Banks such participations in the Loans made by them as shall be necessary to
cause such purchasing Bank to share the excess payment pro rata with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Bank, such purchase shall to that
extent be rescinded and each other Bank shall repay to the purchasing Bank the
purchase price paid therefor, together with an amount equal to such paying
Bank's ratable share (according to the proportion of (i) the amount of such
paying Bank's required repayment to the purchasing Bank to (ii) the total amount
so recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect of the total amount so recovered. The
relevant Borrower agrees that any Bank so purchasing a participation from
another Bank may, to the fullest extent permitted by law, exercise all its
rights of payment (including the right of set-off with respect to such
participation) as fully as if such Bank were the direct creditor of such
Borrower in the amount of such participation. The Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.

         2.14 Non-Allocated Payments. Notwithstanding any other provision of
this Agreement, the parties agree that (a) the obligations of each Borrower
hereunder are, and at all times shall continue to be, several and not joint, (b)
the assets and liabilities of each Borrower are separate and distinct from the
assets and liabilities of the other Borrower and (c) a Borrower shall


                                       9


not be liable or charged for any debt, obligation, liability, fee or expense
arising under this Agreement or the Notes of the other Borrower. The Borrowers
shall (i) as provided in Section 4.1(h), (ii) to the extent feasible, at least
five (5) Business Days in advance of a date on which a payment in respect of a
debt, obligation, liability, fee or expense arising hereunder (other than
commitment fees, principal of or interest on a Loan, expenses allocable
specifically to one Borrower hereunder, indemnities allocable to one Borrower in
accordance with the terms and conditions hereof or Taxes or Other Taxes
allocated to a particular Borrower and arrangement and agency fees) shall be due
and payable and (iii) upon request of the Agent, cause to be provided to the
Agent an Allocation Notice; provided, however, should the Borrowers fail to
deliver to the Agent an Allocation Notice with respect to such amounts within
five Business Days following a request for the same by the Agent, the Borrowers
shall be liable therefor to the Agent and/or the Banks on a pro rata basis in
the proportion of the respective net asset value of each Borrower on any date of
determination thereof.

         2.15 [Reserved].

         2.16 Swing Loans. BofA may elect in its sole discretion to make loans
that shall bear interest at the Federal Funds Rate plus 0.50% per annum (each, a
"Swing Loan") to a Borrower solely for BofA's own account from time to time on
or after the Refinancing Date and prior to the Commitment Termination Date up to
an aggregate principal amount at any one time outstanding to both of the
Borrowers not to exceed $25,000,000; provided, however, that after giving effect
to any Swing Loan, the aggregate principal amount of all outstanding Loans shall
not exceed the least of (a) the Commitment of BofA; (b) the combined Commitments
of all the Banks; and (c) the Borrowing Base. BofA may make Swing Loans (subject
to the conditions precedent set forth in Section 4.2), provided that BofA
receives notice no later than 2:00 p.m. (Eastern time) either (i) by facsimile
transmission of a Loan Request or (ii) by telephone notice from an Authorized
Officer of the relevant Borrower for funding of a Swing Loan on the Business Day
on which such Swing Loan is requested to be made. BofA shall not make any Swing
Loan after BofA becomes aware that one or more of the conditions precedent
contained in Section 4.2 is not satisfied until such conditions have been
satisfied or waived.

         If a Borrower shall request by telephonic notice and obtain a Swing
Loan, it shall deliver promptly by facsimile transmission to BofA a Loan Request
signed by an Authorized Officer of the Borrower confirming such telephonic
notice for a Swing Loan. If the information contained in any such Loan Request
differs in any material respect from the action taken by BofA, the records of
BofA shall govern, absent manifest error.

         Each outstanding Swing Loan shall be payable no later than the seventh
Business Day next following the day the Swing Loan was made, with interest at
the Federal Funds Rate plus 0.50% per annum, and shall be subject to all the
terms and conditions applicable to Loans, except that all interest thereon shall
be payable to BofA solely for its own account. On the due date for such Swing
Loan, unless the relevant Borrower delivers or has previously delivered to BofA
a notice of its intention to repay and does repay the Swing Loan prior to 12:00
noon (Eastern time), such Swing Loan shall automatically convert to a Federal
Funds Rate Loan under this Agreement, and each Bank (other than BofA) shall
irrevocably and unconditionally purchase from BofA, without recourse or
warranty, an undivided interest and participation in such Swing Loan in an
amount equal to such Bank's Pro Rata Share and promptly pay such amount to BofA


                                       10

in immediately available funds (which payment shall be due by 2:00 p.m. (Eastern
time) on such day if BofA requests payment therefor prior to 12:00 noon (Eastern
time) on such day; otherwise such payment shall be due by 2:00 p.m. (Eastern
time) on the first Business Day after BofA requests the same). Such payment
shall be made by the other Banks whether or not an Event of Default or a Default
is then continuing or any other condition precedent set forth in Section 4.2 is
then met and whether or not the relevant Borrower has then requested a Loan in
such amount. If such amount is not in fact paid to BofA by any Bank, BofA shall
be entitled to recover such amount on demand from such Bank, together with
accrued interest thereon from the due date therefor (if made prior to 2:00 p.m.,
Eastern time) on any Business Day until the date such amount is paid to BofA by
such Bank, at the Federal Funds Rate. The failure of any Bank to pay such amount
to BofA shall not relieve any other Bank of its obligation to BofA hereunder.

         2.17 Extension of Commitment Termination Date. Between 60 and 45 days
prior to the Commitment Termination Date, the Borrowers may, by notice to the
Agent, request that all Banks extend for an additional 364 days the Commitment
Termination Date. Such extension so requested shall become effective if (and
only if) on or prior to 30 days after such notice each Bank shall have consented
to such extension in writing by notice to the Agent. If a Bank shall not respond
to any such request, it shall be deemed to have refused to extend. If any Bank
(a "Non-Extending Bank") shall not agree to such extension, but Banks holding at
least 80% of the Commitments shall agree to such extension, the Borrowers may
request one or more of the other Banks to purchase the Commitment of the
Non-Extending Bank or, with the consent of the Agent, the Borrowers may request
an Assignee to purchase the Commitment of the Non-Extending Bank. Such purchase
shall be subject to the payment to the Non-Extending Bank of all accrued and
unpaid interest, principal, fees and other amounts due and owing hereunder. Any
such purchase by such other Bank(s) or Assignee shall be subject to the terms of
Section 9.7, except that the assignment fee contemplated by Section 9.7(b) shall
not be payable. The respective obligations of the Borrowers to any Non-Extending
Bank under Sections 2.9, 3.1, 3.3, 3.4, 9.4 and 9.5, and the obligations of such
Non-Extending Bank under Sections 8.7 and 9.8, shall in each case survive and
continue in full force and effect after the date on which such Non-Extending
Bank shall cease to be a Bank hereunder.

                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.1 Taxes.

                  (a) Any and all payments by a Borrower to each Bank or the
         Agent under this Agreement and any other Credit Document shall be made
         free and clear of, and without deduction or withholding for, any Taxes
         with respect to such Borrower's payments. In addition, the relevant
         Borrower shall pay all of its Other Taxes which have been reasonably
         allocated to it.

                  (b) The relevant Borrower agrees to indemnify and hold
         harmless each Bank and the Agent for the full amount of its Taxes or
         its Other Taxes in connection with a payment by it (including any of
         its Taxes or its Other Taxes imposed by any jurisdiction on amounts
         payable by it under this Section) paid by the Bank or the Agent and any


                                       11

         liability (including penalties, interest, additions to tax and expenses
         other than penalties, additions to tax, interest and expenses arising
         solely as a result of the willful misconduct or gross negligence of
         such Bank or Agent) arising therefrom or with respect thereto, whether
         or not such Taxes or Other Taxes were correctly or legally asserted.
         Payment under this indemnification shall be made within 30 days after
         the date the Bank or the Agent makes written demand therefor to the
         relevant Borrower including with such demand an identification of the
         Taxes or Other Taxes (and amounts thereof) with respect to which such
         demand for indemnification is being sought.

                  (c) If the relevant Borrower shall be required by law to
         deduct or withhold any of its Taxes or Other Taxes from or in respect
         of any sum payable hereunder to any Bank or the Agent, then:

                           (i) the sum payable shall be increased as necessary
                  so that after making all required deductions and withholdings
                  (including deductions and withholdings applicable to
                  additional sums payable under this Section), such Bank or the
                  Agent, as the case may be, receives an amount equal to the sum
                  it would have received from such Borrower had no such
                  deductions or withholdings been made;

                           (ii) such Borrower shall make such deductions and
                  withholdings;

                           (iii) such Borrower shall pay the full amount
                  deducted or withheld to the relevant taxing authority or other
                  authority in accordance with applicable law; and

                           (iv) such Borrower shall also pay to the Agent for
                  the account of such Bank, at the time interest is paid, all
                  additional amounts which the respective Bank specifies as
                  necessary to preserve the after-tax yield the Bank would have
                  received if such Taxes or Other Taxes had not been imposed.

                  (d) Within 30 days after the date of any payment by the
         relevant Borrower of its Taxes or Other Taxes, such Borrower shall
         furnish the Agent the original or a certified copy of a receipt
         evidencing payment thereof or other evidence of payment satisfactory to
         the Agent.

                  (e) If the relevant Borrower is required to pay additional
         amounts to any Bank or the Agent pursuant to subsections (b) or (c) of
         this Section, then such Bank shall use reasonable efforts (consistent
         with legal and regulatory restrictions) to change the jurisdiction of
         its Lending Office so as to eliminate any such additional payment by
         such Borrower which may thereafter accrue, if such change in the
         judgment of such Bank is not otherwise disadvantageous to such Bank. A
         Borrower shall have no obligation to pay any amounts or increase any
         amounts payable to any Bank pursuant to this Section 3.1 which are
         owing on account of such Bank's failure to comply with its obligations
         under Section 8.10.

                  (f) Within 30 days after the written request of a Borrower,
         each Bank or Agent shall execute and deliver to such Borrower such
         certificates or forms as are


                                       12

         reasonably requested by such Borrower in such request, that can be
         furnished consistent with the facts and that are necessary to assist
         such Borrower in applying for refunds of its Taxes or its Other Taxes
         paid or indemnified by such Borrower hereunder. If a Bank or Agent
         receives a refund of any Taxes or Other Taxes with respect to which a
         Borrower has made a payment of additional amounts, such Bank or Agent
         shall pay over such refund to such Borrower within 30 days of receipt
         in an amount not in excess of the payments made by such Borrower with
         respect thereto.

         3.2 Illegality.

                  (a) If any Bank reasonably determines that the introduction of
         any Requirement of Law, or any change in any Requirement of Law, or in
         the interpretation or administration of any Requirement of Law, has
         made it unlawful, or that any central bank or other Governmental
         Authority has asserted that it is unlawful, for any Bank or its
         applicable Lending Office to make Offshore Rate Loans, then, on notice
         thereof by the Bank to the Borrowers through the Agent, any obligation
         of that Bank to make Offshore Rate Loans shall be suspended until the
         Bank gives notice, and the Bank agrees promptly to give such notice, to
         the Agent and the Borrowers when the circumstances giving rise to such
         determination no longer exist.

                  (b) If a Bank reasonably determines that it is unlawful to
         maintain any Offshore Rate Loan, each Borrower shall, upon its receipt
         of notice of such fact and demand from such Bank (with a copy to the
         Agent), prepay in full its respective Offshore Rate Loans of that Bank
         then outstanding, together with interest accrued thereon and amounts
         required under Section 3.4, either on the last day of the Interest
         Period thereof, if the Bank may lawfully continue to maintain such
         Offshore Rate Loans to such day, or immediately, if the Bank may not
         lawfully continue to maintain such Offshore Rate Loan, as provided in a
         notice from the Bank to each respective Borrower. If a Borrower is
         required to so prepay any of its Offshore Rate Loan, then concurrently
         with such prepayment, the Borrower may borrow from the affected Bank,
         in the amount of such repayment, a Federal Funds Rate Loan.

                  (c) If the obligation of any Bank to make or maintain Offshore
         Rate Loans has been so terminated or suspended, a Borrower may elect,
         by giving notice to the Bank through the Agent, that all of its Loans
         that would otherwise be made by the Bank as Offshore Rate Loans shall
         be instead Federal Funds Rate Loans.

                  (d) Before giving any notice to the Agent under this Section,
         the affected Bank shall designate a different Lending Office with
         respect to its Offshore Rate Loans if such designation will avoid the
         need for giving such notice or making such demand and will not, in the
         judgment of the Bank, be illegal or otherwise materially
         disadvantageous to the Bank.

         3.3 Increased Costs and Reduction of Return.

                  (a) If any Bank reasonably determines that, due to the
         introduction of or any change in or in the interpretation of any law or
         regulation or the compliance by that Bank


                                       13

         with any guideline or request made subsequent to the date of this
         Agreement from any central bank or other Governmental Authority
         (whether or not having the force of law), there shall be any increase
         in the cost to such Bank (not included in the calculation of the
         Eurodollar Reserve Percentage) of agreeing to make or making, funding
         or maintaining any Offshore Rate Loans to a Borrower, then such
         Borrower shall be liable for, and shall from time to time within 30
         days after demand (with a copy of such demand to be sent to the Agent)
         pay to the Agent, for the account of such Bank, additional amounts as
         are sufficient to compensate such Bank for such increased costs with
         respect to such Borrower.

                  (b) If any Bank shall have reasonably determined that (i) the
         introduction of any Capital Adequacy Regulation, (ii) any change in any
         Capital Adequacy Regulation, (iii) any change in the interpretation or
         administration of any Capital Adequacy Regulation by any central bank
         or other Governmental Authority charged with the interpretation or
         administration thereof or (iv) compliance by such Bank (or its Lending
         Office) or any corporation controlling such Bank with any guideline or
         request made subsequent to the date hereof with respect to any Capital
         Adequacy Regulation affects or would affect the amount of capital
         required or expected to be maintained by such Bank or any corporation
         controlling such Bank and (taking into consideration such Bank's or
         such corporation's policies with respect to capital adequacy and such
         Bank's desired return on capital) and such Bank determines that, as a
         result of any of the foregoing, the amount of such capital is increased
         as a consequence of its Commitment, Loans, credits or other obligations
         under this Agreement, then, within 30 days after demand therefor
         accompanied by the certificate contemplated by Section 3.6 of such Bank
         to each affected Borrower through the Agent, the relevant Borrower
         shall pay to the Bank, from time to time as specified by the Bank,
         additional amounts sufficient to compensate the Bank for any reduced
         return on such capital reasonably allocated to the relevant Borrower as
         a result of such increase.

         3.4 Funding Losses. The relevant Borrower will reimburse each Bank and
hold each Bank harmless from any loss or expense which the Bank may reasonably
sustain or incur as a consequence of:

                  (a) the failure of such Borrower to make on a timely basis any
         payment of principal of any Offshore Rate Loan;

                  (b) the failure of such Borrower to borrow, continue or
         convert a Loan after such Borrower has given (or is deemed to have
         given) a Loan Request or a Conversion/Continuation Notice;

                  (c) the failure of such Borrower to make any prepayment in
         accordance with any notice delivered under Section 2.6; or

                  (d) the prepayment or other payment (including after
         acceleration thereof) of any of such Borrower's Offshore Rate Loans on
         a day that is not the last day of the relevant Interest Period,


                                       14


including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained. For purposes of
calculating amounts payable by a Borrower to the Banks under this Section and
under Section 3.3(b), each of such Borrower's Offshore Rate Loan made by a Bank
(and each related reserve, special deposit or similar requirement) shall be
conclusively deemed to have been funded at the IBOR used in determining the
Offshore Rate for such Offshore Rate Loan by a matching deposit or other
borrowing in the interbank eurodollar market for a comparable amount and for a
comparable period, whether or not such Offshore Rate Loan is in fact so funded.

         3.5 Inability to Determine Rates. If the Agent determines that for any
reason adequate and reasonable means do not exist for determining a relevant
Borrower's Offshore Rate for any requested Interest Period with respect to a
proposed Offshore Rate Loan or that the Offshore Rate applicable pursuant to
Section 2.8(a) for any requested Interest Period with respect to a proposed
Offshore Rate Loan does not adequately and fairly reflect the cost to any Bank
of funding such Loan, the Agent will promptly so notify the relevant Borrower
and each Bank. Thereafter, the obligation of the Banks to make or maintain such
Offshore Rate Loans hereunder shall be suspended until the Agent gives notice
(and, if appropriate, the Agent shall give such notice) to the relevant Borrower
that adequate and reasonable means do exist for determining such Offshore Rate
or such Offshore Rate does adequately and fairly reflect the costs to the Banks
of funding such Loans. Upon receipt of such notice, such Borrower may revoke any
Loan Request or Conversion/Continuation Notice then submitted by it. If such
Borrower does not revoke such Notice, the Banks shall make, convert or continue
such Loans at the end of the applicable Interest Period, as proposed by such
Borrower, in the amount specified in the applicable notice submitted by such
Borrower, but such Loans shall be made, converted or continued as Federal Funds
Rate Loans instead of Offshore Rate Loans until the Agent revokes such notice.

         3.6 Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the relevant Borrower (with
a copy to the Agent) a certificate setting forth in reasonable detail the amount
payable to the Bank hereunder, and such certificate shall be conclusive and
binding on the Borrower in the absence of manifest error.

         3.7 Substitution of Banks. Upon the receipt by a Borrower from any Bank
(an "Affected Bank") of a claim for compensation against such Borrower under
Section 3.1 or Section 3.3 or any circumstances exist with respect to such Bank
described in Section 3.2, such Borrower may: (a) request the Affected Bank to
use its best efforts to obtain a replacement bank or financial institution
satisfactory to such Borrower to acquire and assume all or a ratable part of all
of such Affected Bank's Loans and Commitment (a "Replacement Bank"); (b) request
one or more of the other Banks to acquire and assume all or part of such
Affected Bank's Loans and Commitment (it being understood that no such other
Bank shall in any way be required to effect any such acquisition and
assumption); or (c) designate a Replacement Bank. Any such designation of a
Replacement Bank under clause (a) or (c) shall be subject to the prior written
consent of the Agent (which consent shall not be unreasonably withheld) and
payment in full of all amounts due and owing hereunder to the Replacement Bank.
Each Bank which is an Affected Bank agrees to execute the necessary
documentation to assign its interest to a


                                       15

Replacement Bank upon five (5) days' written notice from such Borrower after a
Replacement Bank is identified.

         3.8 Survival. The agreements and obligations of the respective
Borrowers in Sections 3.1, 3.3 and 3.4 shall survive the payment of all other
Obligations.

                                   ARTICLE IV

                     CONDITIONS TO AMENDMENTS AND BORROWING

         4.1 Conditions to Amendment and Restatement. This amended and restated
Agreement shall take effect from the first day that the Agent shall have
received counterparts hereof signed by the Borrowers, the Agent and the Banks,
and each of the following conditions set forth in this Section 4.1 has been
waived by the Agent and each Bank or met (the "Refinancing Date").

                  (a) The Agent shall have received from each Borrower a
         certificate, dated the Refinancing Date, of its Secretary or Assistant
         Secretary as to

                           (i) resolutions of its board of trustees then in full
                  force and effect authorizing the execution, delivery and
                  performance of this amended and restated Agreement, the Notes
                  and each other Credit Document to be executed by it and the
                  Borrower's Declaration of Trust as amended or amended and
                  restated to the date hereof and By-Laws;

                           (ii) the incumbency and signatures of those of its
                  officers or agents authorized to act with respect to this
                  amended and restated Agreement, the Notes and each other
                  Credit Document executed by it;

                           (iii) such Borrower's valid existence as evidenced by
                  a certificate issued by the Secretary of State of the
                  Commonwealth of Massachusetts and appended to the relevant
                  certificate of its Secretary or Assistant Secretary; and

                           (iv) the fact that the agreements delivered by such
                  Borrower pursuant to Section 4.1(e) constitute all such
                  agreements between the Borrower and the Adviser as of such
                  date;

         upon which certificate the Agent and each Bank may conclusively rely as
         to the matters described in clauses (i) and (ii) until they shall have
         received a further certificate from such Borrower canceling or amending
         such prior certificate.

                  (b) The Agent shall have received for the account of each Bank
         other than Harris Trust and Savings Bank and BNP Paribas a Note from
         each Borrower duly executed and delivered by such Borrower and made
         payable to the order of such Bank in the principal amount of such
         Bank's Commitment.

                  (c) The Agent shall have received (i) an opinion, dated the
         Refinancing Date and addressed to the Agent and all Banks, from

         Exhibit 4.1(c)-1 and (ii) an opinion, dated the Refinancing Date and
         addressed to the Agent and all Banks, from Mayer, Brown & Platt,
         counsel to the Agent, substantially in the form of Exhibit 4.1(c)-2.

                  (d) The Agent shall have received evidence of payment of all
         accrued and unpaid fees, costs and expenses to the extent then due and
         payable on the Refinancing Date, together with Attorney Costs of the
         Agent to the extent invoiced prior to or on the Refinancing Date, plus
         such additional amounts of Attorney Costs as shall constitute the
         Agent's reasonable estimate of Attorney Costs incurred or to be
         incurred by it through the closing proceedings (provided that such
         estimate shall not thereafter preclude final settling of accounts
         between the Borrowers and the Agent), including any such costs, fees
         and expenses then due and payable arising under or referenced in
         Section 2.9(a) and those then due and payable pursuant to Section 9.4.

                  (e) The Agent shall have received copies of each investment

         Date.

                  (f) The Agent shall have received copies of the most recent
         prospectus and statement of additional information for the Borrowers in
         effect as of the Refinancing Date.

                  (g) The Agent shall have received from the Borrowers an
         Allocation Notice.

         4.2 All Borrowings. The obligation of (i) each Bank to fund any Loan
(other than the reimbursement of the Swing Loan pursuant to Section 2.16) on the
occasion of any Borrowing (including the initial Borrowing) by a Borrower and
(ii) BofA to make any Swing Loan to a Borrower shall be subject to the
satisfaction of each of the conditions precedent set forth in this Section 4.2.

                  (a) No Default shall have occurred and be continuing with
         respect to the Borrower on such date.

                  (b) The representations and warranties of the relevant
         Borrower contained in Article V (except to the extent such
         representations and warranties relate solely to an earlier date, in
         which case they shall be true and correct as of such earlier date)
         shall be true and correct in all material respects on and as of the

         to such Borrowing, as if then made.

                  (c) In the case of a Borrowing, the Agent shall have received
         a Loan Request for such Borrowing. Each of the delivery of a Loan
         Request and the acceptance by the relevant Borrower of the proceeds of
         such Borrowing shall constitute a representation and warranty by the
         relevant Borrower that on the date of such Borrowing (both immediately
         before and after giving effect to such Borrowing and the application of
         the proceeds thereof), the statements made in Sections 4.2(a), (b), (d)
         and (e) are true and correct with respect to such Borrower.


                                       17


                  (d) Both before and after the Loan in question, such
         Borrower's Asset Coverage Ratio shall be at least 4 to 1.

                  (e) There shall not have been outstanding to such Borrower as
         of the close of business (Eastern time) on the day preceding the
         proposed Borrowing Date for the requested Loan a Loan that had been
         outstanding for more than sixty (60) days.

         Any instrument, agreement or other document to be received by the Agent
pursuant to this Article IV, and any other condition precedent required to be
met or satisfied under this Article IV, shall be in form and substance
reasonably satisfactory to the Agent and each Bank and in sufficient copies for
each Bank.

         4.3 Consequences of Effectiveness, etc. On the Refinancing Date the

of the parties hereto shall be governed by this amended and restated Agreement;
provided that rights and obligations of the parties hereto with respect to the
period prior to the Refinancing Date shall continue to be governed by the
provisions of the Existing Credit Agreement. On the Refinancing Date, the Pro
Rata Share of each Bank shall immediately become the percentage set forth
opposite the name of such Bank on Schedule II. With effect from and including

         In order to induce the Banks and the Agent to enter into this Agreement
and to make Loans hereunder, each Borrower represents and warrants unto the
Agent and each Bank with respect to itself as set forth in this Article V. The

1933, as amended, pursuant to one or more registration statements, including any
related prospectus, that is or are currently effective. The Borrower is in good
standing and is duly qualified to do business in each state where, because of
the nature of its activities or properties, such qualification is required,
except where the failure to be so qualified could not reasonably be expected to
have a material adverse effect on the business or operations of the Borrower.

         5.2 Authorization. The Borrower is duly authorized to execute and
deliver this Agreement and the Notes and, so long as this Agreement shall remain
in effect, the Borrower will continue to be duly authorized to borrow monies

         5.3 No Conflicts. The execution, delivery and performance by the
Borrower of this Agreement and the Notes do not and, so long as this Agreement
shall remain in effect with respect to them, will not (a) conflict with any
provision of law, (b) conflict with the Trust Agreement or its by-laws, (c)
conflict with any material agreement or instrument binding upon it, (d) conflict
with the Borrower's most recent prospectus or its most recent statement of
additional information, (e) conflict with any court or administrative order or
decree applicable to it or (f) require or result in the creation or imposition
of any Lien on any of its assets.

         5.4 Validity and Binding Effect. This Agreement is, and the Notes when
duly executed and delivered will be, the legal, valid and binding obligation of
the Borrower, enforceable against it in accordance with their terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
receivership, fraudulent conveyance, fraudulent transfer, moratorium or other
similar laws of general application affecting the enforcement of creditors'
rights or by general principles of equity limiting the availability of equitable
remedies.

         5.5 No Default. The Borrower is not in default under any agreement or
instrument to which it is a party or by which any of its respective properties
or assets is bound or affected, other than defaults that could not reasonably be
expected to result in a Material Adverse Change with respect to such Borrower.
To the best of its knowledge, no Default with respect to it has occurred and is
continuing.

         5.6 Financial Statements. The Borrower's most recent audited Statement
of Assets and Liabilities and its most recent semi-annual asset statement,
copies of which have been or will be furnished to the Banks, have been prepared
in conformity with GAAP applied on a basis consistent with that of the preceding
Fiscal Year or period and present fairly its financial condition as at such
dates and the results of its operations for the periods then ended, subject (in
the case of the interim financial statement) to year-end audit adjustments.
Since the date of its most recent Statement of Assets and Liabilities and such
semi-annual asset statement, there has been no Material Adverse Change with
respect to such Borrower.

         5.7 Litigation. No claims, litigation, arbitration proceedings or
governmental proceedings that could reasonably be expected to result in a
Material Adverse Change with respect to such Borrower are pending or, to the
best of its knowledge, threatened against or affecting such Borrower, except
those referred to in Exhibit 5.7-1. Other than any liability incident to such
claims, litigation or proceedings or provided for or disclosed in the financial
statements referred to in Section 5.6 or listed on Exhibit 5.7-2, to the best of
its knowledge, it has no contingent liabilities which are material to it other
than those incurred in the ordinary course of business.

         5.8 Liens. None of the Borrower's property, revenues or assets is
subject to any Lien, except (a) Liens in favor of the Banks, if any, (b) Liens

appropriate proceedings and as to which such reserves or other appropriate
provisions as may be required by GAAP are being maintained, (c) Liens as are
necessary in connection with a secured letter of credit opened by or for it in

other authorized investments, (e) Liens arising under any custodian agreement to
which it is a party, (f) other Liens on assets with a value no greater than
$2,000,000 and (g) Liens in connection with reverse repurchase transactions.

venturer in any partnership or joint venture.

         5.10 Purpose. The proceeds of the Loans will be used by it for
short-term liquidity and other temporary emergency purposes, which purposes are
permitted under the Act and by its prospectus and statement of additional
information. Neither the making of any Loan nor the use of the proceeds thereof
will violate or be inconsistent with the provisions of FRB Regulation T, U or X.
It acknowledges that Loans made to it may be deemed by the FRB to be "purpose
loans" under Regulation U because of its status as an investment company (or the
functional equivalent thereof).

         5.11 Compliance and Government Approvals. The Borrower is in compliance
with all statutes and governmental rules and regulations applicable to it,
including, without limitation, the Act, other than incidents of non-compliance
that could not reasonably be expected to result in a Material Adverse Change
with respect to such Borrower. No authorization or approval or other action by,
and no notice to or filing with, any governmental authority or regulatory body
or other person is required for the due execution, delivery or performance by
the Borrower of this Agreement, the Notes or any of the other Credit Documents
and the Borrowings, other than those that have been obtained or made.

maintained, nor is it liable under, any Plan.

         5.13 Taxes. The Borrower has filed all tax returns that are required to
have been filed and has paid, or made adequate provisions for the payment of,
all of its Taxes that are due and payable, except such Taxes, if any, as are
being contested in good faith and by appropriate proceedings and as to which
such reserves or other appropriate provisions as may be required by GAAP have
been maintained. The Borrower is not aware of any proposed assessment against it
for such additional Taxes (or any basis for any such assessment) which might be
material in amount to it. The Borrower has substantially complied with all
requirements of the Code applicable to regulated investment companies so as to
be relieved of federal income tax on net investment income and net capital gains
distributed to its shareholders.

         5.14 Subsidiaries; Investments. The Borrower has no Subsidiaries or
equity investments or any interest in any other Person other than portfolio
securities (including investment company securities) which may have been
acquired in the ordinary course of business.

Borrower to the Banks in connection herewith contains any untrue statement of
any material fact as of the date


                                       20

when made or omits to state any material fact necessary to make the statements
herein or therein taken as a whole not misleading as of the date when made in
light of the circumstances in which the same were made.

         5.16 Investment Policies. The Borrower's assets are being invested
substantially in accordance with the investment policies and restrictions set
forth in its most recent prospectus and its most recent statement of additional
information other than any de minimis violation of such policies arising in the
ordinary course of business which the Borrower is in the process of correcting.

         5.17 Regulations T, U and X. The Borrower is not engaged in the
business of extending credit for the purpose of purchasing or carrying margin
stock.

         5.18 Status of Loans. The Borrower's obligation in connection with the
repayment of any Loans made to it hereunder shall at all times rank at least
pari passu in priority of payment with all of its other present and future
unsecured and unsubordinated Indebtedness.

         5.19 Prospectus. The asset coverage restrictions on the Borrower in its
prospectus are not more restrictive than the provisions of Section 6.12 hereof.

         5.20 Affiliated Person. To the best of the knowledge of the Borrower as
of the date hereof, it is not an "Affiliated Person" or an "Affiliated Person"
of such an "Affiliated Person", as defined in the Act, of any Bank party to the
Agreement as of the date hereof.

                                   ARTICLE VI

                                    COVENANTS

         From the date of this Agreement (or, in the case of Van Kampen Senior
Floating Rate Fund, the date of the second amendment and restatement of this
Agreement) and thereafter until the expiration or termination of the Commitments
and until all Obligations other than those expressly stated to survive
expiration or termination of this Agreement have been paid or performed in full,
each Borrower, as to itself, shall perform the obligations made applicable to it
in this Article VI.

         conformity with GAAP and certified by Deloitte & Touche LLP or such

         such calendar quarter and (ii) a certificate signed by an Authorized
         Officer certifying that, to the best of such Person's knowledge, no

                  (d) (i) Within 15 days following the filing thereof, any

                  (e) Promptly from time to time such other reports or
         information as any of the Banks may reasonably request.

         6.2 Notices. The Borrower shall notify the Agent in writing of any of
the following immediately upon learning of the occurrence thereof, describing
the same and, if applicable, stating the steps being taken by the Person(s)
affected with respect thereto:

                  (a) the occurrence of a Default;

                  (b) the institution of any litigation, arbitration proceeding
         or governmental proceeding which is likely to result in a Material
         Adverse Change with respect to such Borrower;

                  (c) the entry of any judgment or decree against it if the
         aggregate amount of all judgments and decrees then outstanding against
         it exceeds the lesser of 5% of its Net Asset Value or $5,000,000 after

         respect to which the insurer has assumed responsibility in writing and
         (ii) the amount for which it is otherwise indemnified if the terms of
         such indemnification and the Person providing such indemnification are
         satisfactory to the Majority Banks;


                                       22


                  (d) the occurrence of a change of its name (whether of its
         legal name or a "d/b/a" designation). The Borrower shall promptly
         execute and deliver to each Bank a new Note for execution in its new
         name, together with such other documents in connection therewith as the
         Banks shall reasonably request; and

                  (e) the scheduling of consideration by the board of trustees
         of the Borrower of a change in the Borrower's Adviser (except as
         contemplated hereby), distributor, administrator, custodian (unless
         such custodian is a Bank) or independent accountant, or the appointment
         of any sub-adviser or any Person acting in a similar capacity to an
         Adviser (except as contemplated hereby); provided that a mailing to
         shareholders with respect to any of the foregoing shall not be deemed
         to be sufficient notice hereunder.

         Notwithstanding anything to the contrary in the foregoing, in the case
         of the matters described in subparagraph (e), the notice contemplated
         by this Section 6.2 shall be given not later than 30 days prior to the
         time (i) the board of trustees of the Borrower is to consider approval
         of such change or appointment or otherwise determines to recommend such
         change or appointment (if necessary) to the Borrower's shareholders for
         their approval and (ii) of any change of the Borrower's custodian;
         provided, however, if in the case of the matters contemplated by
         subparagraph (e) the Borrower could not in good faith have provided the
         specified advance notice, such notice shall be given by the Borrower
         immediately following the earliest feasible time the notice could have
         been provided.

         6.3 Existence. The Borrower, except as specified in Section 6.11(a),
shall maintain and preserve its existence as a registered investment company,
and maintain and preserve all rights, privileges, licenses, copyrights,
trademarks, trade names, franchises and other authority to the extent material
and necessary for the conduct of its business in the ordinary course as
conducted from time to time, unless the Borrower has no Loans outstanding and
the Borrower has irrevocably notified the Agent (which shall thereupon promptly
notify the Banks) that it shall not request any Loans hereunder.

         6.4 Nature of Business. The Borrower shall continue in, and limit its
operations to, the business of a closed-end management investment company,
within the meaning of the Act, and maintain in full force and effect at all
times all governmental licenses, registrations, permits and approvals necessary
for the continued conduct of its business, including, without limitation, its
registration with the Securities and Exchange Commission under the Act as a
closed-end investment company, except where the failure to so maintain such
licenses, registrations, permits and approvals would not result in a Material
Adverse Change with respect to such Borrower.

         6.5 Books, Records and Access. The Borrower shall maintain complete and
accurate books and records in which full and correct entries in conformity with
GAAP shall be made of all transactions in relation to its business and
activities; upon reasonable notice, the Borrower shall at the expense of the
Banks prior to Default or at the expense of the Borrower after Default permit
access by the Banks to its books and records during normal business hours and
permit the Banks to make copies of such books and records; provided that the
Banks agree that Borrower shall not be required to provide the Banks with access
to such of its books and records that are


                                       23

subject to confidentiality agreements which prohibit such access or which are
proprietary in nature.

         6.6 Insurance. The Borrower shall maintain in full force and effect
insurance to such extent and against such liabilities as is commonly maintained
by companies similarly situated, including but not limited to (i) such fidelity
bond coverage as shall be required by Rule 17g-1 promulgated under the Act or
any similar or successor provision and (ii) errors and omissions, director and
officer liability and other insurance against such risks and in such amounts
(and with such co-insurance and deductibles) as is usually carried by other
companies of comparable size and financial strength engaged in the same or
similar businesses and similarly situated and will, upon the reasonable request
of the Agent, furnish to the Banks a certificate of an Authorized Officer
setting forth the nature and extent of all insurance maintained by the Borrower
in accordance with this Section.

         6.7 Investment Policies and Restrictions.

                  (a) The Borrower, without prior written notice to the Agent of
         at least 30 days, shall not rescind, amend or modify any investment
         policy described as "fundamental" in any prospectus or any registration
         statement(s) that may be on file with the Securities and Exchange
         Commission with respect thereto (collectively herein, a "proposed
         change"). If, in the reasonable judgment of the Majority Banks, such
         proposed change will result in a change in the Banks' analysis of the
         creditworthiness of the Borrower, the Agent shall notify the Borrower
         of such decision; thereafter, if such proposed change is implemented,
         the Banks may terminate their Commitments to lend to the Borrower, and
         all Loans outstanding to the Borrower shall become immediately due and
         payable.

                  (b) The Borrower's investment in any assets shall be made in
         accordance with its investment policies and restrictions set forth in
         its most recent prospectus and statement of additional information
         other than any investment which shall constitute a de minimis violation
         of such policies arising in the ordinary course of business which the
         Borrower is in the process of correcting.

         6.8 Taxes. The Borrower shall pay when due all of its Taxes, unless and
only to the extent that such Taxes are being contested in good faith and by
appropriate proceedings and it shall have set aside on its books such reserves
or other appropriate provisions therefor as may be required by GAAP. The
Borrower shall at all times comply with all requirements of the Code applicable
to regulated investment companies, to such effect as not to be subject to
federal income taxes on net investment income and net capital gains distributed
to its shareholders.

         6.9 Compliance. The Borrower shall comply in all material respects with
all statutes and governmental rules and regulations applicable to it, including,
without limitation, the Act.

         6.10 Pension Plans. The Borrower shall not enter into, or incur any
liability relating to, any Plan.

         6.11 Merger, Purchase and Sale. The Borrower shall not:


                                       24


                  (a) be a party to any merger or consolidation; provided,
         however, that the Borrower may merge or consolidate with any other
         Person in accordance with 17 C.F.R. Section 270.17a-8 if (i) such
         merger or consolidation complies in all material respects with the
         requirements of 17 C.F.R. Section 270.17a-8 and all rules promulgated
         in connection therewith, (ii) the surviving entity assumes all of the
         obligations to the Banks of the Borrower prior to such merger or
         consolidation and (iii) in the good faith judgment of the Majority
         Banks, the financial condition and investment policies and restrictions
         of the surviving entity are not fundamentally different from those of
         the Borrower prior to such merger or consolidation, unless the Majority
         Banks otherwise consent;

                  (b) except as permitted by Section 6.11(a) and except for
         sales or other dispositions of assets in the ordinary course of its
         business or to meet shareholder redemption requests, sell, transfer,
         convey, lease or otherwise dispose of all or any substantial part of
         its assets; provided, however, that the Borrower may sell substantially
         all of its assets to another Person in accordance with 17 C.F.R.
         Section 270.17a-8 if (i) such sale complies in all material respects
         with the requirements of 17 C.F.R. Section 270.17a-8 and all rules
         promulgated in connection therewith, (ii) the purchasing entity assumes
         all obligations to the Banks of the Borrower prior to such sale and
         (iii) in the good faith judgment of the Majority Banks, the financial
         condition and investment policies and restrictions of the purchasing
         entity are not fundamentally different from those of the Borrower prior
         to the asset sale; or

                  (c) except as permitted by Section 6.11(a), purchase or
         otherwise acquire all or substantially all the assets of any Person
         without the review and consent thereto of the Majority Banks, which
         consent shall not be unreasonably withheld.

         For purposes of this Section 6.11 only, a sale, transfer, conveyance,
         lease or other disposition of assets shall be deemed to be a
         "substantial part" of the assets of the Borrower only if the value of
         such assets, when added to the value of all other assets sold,
         transferred, conveyed, leased or otherwise disposed of by the Borrower
         (other than in the normal course of business or in a manner otherwise
         consistent with the Borrower's investment policies and other than
         payments or transfers made to satisfy quarterly tenders of shares of
         the Borrower) during the same Fiscal Year, exceeds 15% of the
         Borrower's Total Assets determined as of the end of the immediately
         preceding Fiscal Year.

         6.12 Asset Coverage Ratio. The Borrower shall not at any time permit

Taxes not delinquent or Taxes being contested in good faith and by appropriate
proceedings and as to which such reserves or other appropriate provisions as may
be required by GAAP are being maintained, (iii) Liens as are necessary in

shall be excluded from calculation of its Borrowing Base. The Borrower shall not
permit "margin stock" as defined in FRB Regulation U (not including shares of
the Borrower itself) to constitute 25% or more of the value (as determined by
any reasonable method) of the assets of the Borrower.

         6.14 Guaranties. The Borrower shall not become or be a guarantor or
surety of, or otherwise become or be responsible in any manner (whether by
agreement to purchase any obligations, stock, assets, goods or services, or to
supply or advance any funds, assets, goods or services or as an account party
under any letter of credit issued in favor of a third party, or otherwise) with
respect to, any undertaking of any other Person, except for the endorsement, in
the ordinary course of collection, of instruments payable to it or its order.

         6.15 Other Agreements. The Borrower shall not enter into any agreement

its obligations hereunder or under any instrument or document delivered or to be
delivered by it hereunder or in connection herewith.

into or be a party to any transaction or arrangement, including, without
limitation, the purchase, sale, loan, lease or exchange of property or the
rendering of any service, with any Related Party, except in the ordinary course
of and pursuant to the reasonable requirements of its business and upon fair and
reasonable terms no less favorable to it than would be obtainable in a
comparable arm's-length transaction with a Person not a Related Party; provided
that any such transaction must be made in substantial compliance with Section 17
of the Act or an exemption therefrom.

         6.17 Other Indebtedness. The Borrower shall not incur or permit to

                                   ARTICLE VII

                                EVENTS OF DEFAULT

         7.1 Events of Default. Each of the following shall constitute an Event
of Default with respect to each Borrower under this Agreement (it being
understood that an Event of Default with respect to one Borrower shall not
constitute an Event of Default with respect to the other Borrower):

                  (a) Default in payment by the Borrower (i) when and as
         required to be paid herein of any amount of principal of any Loan or
         (ii) within five days after the same becomes due of any interest, fee
         or any other amount payable hereunder or under any other Credit
         Document; provided that conversion of a Swing Loan to a Federal Funds
         Rate Loan as contemplated by the second sentence of the third paragraph
         of Section 2.16 shall not constitute an Event of Default under this
         Section 7.1(a).

                  (b) Default by the Borrower in the payment when due, whether
         by acceleration or otherwise (subject to any applicable grace period),
         of any Indebtedness of, or guaranteed by, the Borrower in excess of
         $5,000,000 (other than the Indebtedness evidenced by the Notes).

                  (c) Any event or condition shall occur that results in the
         acceleration of the maturity of any Indebtedness of, or guaranteed by,
         the Borrower in excess of $5,000,000 or enables the holder or holders
         of such other Indebtedness or any trustee or agent for such holders
         (any required notice of default having been given and any applicable
         grace period having expired) to accelerate the maturity of such other
         Indebtedness.

                  (d) The Borrower (i) becomes insolvent, or generally fails to
         pay, or admits in writing its inability to pay, its debts as they
         become due, subject to applicable grace periods, if any, whether at
         stated maturity or otherwise; (ii) voluntarily ceases to conduct its
         business in the ordinary course; (iii) commences any Insolvency
         Proceeding with respect to itself; or (iv) takes any action to
         effectuate or authorize any of the foregoing.

                  (e) (i) Any involuntary Insolvency Proceeding is commenced or
         filed against the Borrower, or any writ, judgment, warrant of
         attachment, execution or similar process is issued or levied against a
         substantial part of its assets, and any such proceeding or petition
         shall not be dismissed, or such writ, judgment, warrant of attachment,
         execution or similar process shall not be released, vacated or fully
         bonded, within 60 days after commencement, filing or levy; (ii) the
         Borrower admits the material allegations of a petition against it in
         any Insolvency Proceeding, or an order for relief (or similar order
         under non-U.S. law) is ordered in any Insolvency Proceeding; or (iii)
         it acquiesces in the appointment of a receiver, trustee, custodian,
         liquidator, mortgagee in possession (or agent therefor) or other
         similar Person for itself or a substantial part of its property or
         business.

                  (f) The Borrower shall default in the performance of its
         agreement under Section 6.4, 6.11 or 6.12.



                                       27




                  (g) The Borrower shall default in the performance of its other
         agreements herein set forth (and not constituting an Event of Default
         under any of the other subsections of this Section 7.1), and such
         default shall continue for 30 days (or five Business Days in the case
         of the agreement contained in the last sentence of the definition of
         "Total Assets") after notice thereof to the Borrower from the Agent.

                  (h) Any representation or warranty made by the Borrower
         herein, or in any schedule, statement, report, notice, certificate or
         other writing furnished by it on or as of the date as of which the
         facts set forth therein are stated or certified, is untrue or
         misleading in any material respect when made or deemed made or any
         certification made or deemed made by it to the Banks is untrue or
         misleading in any material respect on or as of the date made or deemed
         made.

                  (i) There shall be entered against the Borrower one or more
         judgments or decrees which, when taken together, will exceed $5,000,000
         at any one time outstanding, excluding those judgments or decrees (i)
         that shall have been stayed or discharged within 30 calendar days from
         the entry thereof and (ii) those judgments and decrees for and to the
         extent which the Borrower is insured and with respect to which the
         insurer has assumed responsibility in writing or for and to the extent
         which the Borrower is otherwise indemnified if the terms of such
         indemnification and the Person providing such indemnification are
         satisfactory to the Majority Banks.

                  (j) The Borrower shall no longer be in compliance in all
         material respects with all material provisions of the Act after giving
         effect to all notice, cure and contest periods thereunder.

                  (k) The Borrower shall violate or take any action that would
         result in a violation of any of its investment restrictions or
         fundamental investment policies as from time to time in effect, except
         for violations or the taking of such actions that could not reasonably
         be expected to result in a Material Adverse Change with respect to such
         Borrower.

                  (l) There occurs a Change in Control of the Borrower's
         Adviser.

                  (m) The Borrower shall have failed to maintain Van Kampen
         Investment Advisory Corp. or one of its Affiliates as Adviser to it and
         the Majority Banks shall not have consented to such failure.

                  (n) The Borrower shall have changed its distributor,
         custodian, accountant or administrator and the Majority Banks shall not
         have provided their prior written consent to such change; provided,
         however, that the Majority Banks shall not withhold such consent
         unless, based upon their reasonable judgment, the Majority Banks in
         good faith conclude that such change would result in a change in the
         creditworthiness of the Borrower.

         7.2 Remedies. If any Event of Default described in Section 7.1 shall
have occurred and be continuing, the Agent, upon the direction of the Majority
Banks, shall declare the Commitments to be terminated with respect to the
relevant Borrower and such Borrower's



                                       28




obligations under its Notes to be due and payable, whereupon such Commitments
shall immediately terminate with respect to such Borrower and such Borrower's
Notes shall become immediately due and payable, all without advance notice of
any kind (except that if an event described in Section 7.1(d) or Section 7.1(e)
occurs, the Commitments shall immediately terminate with respect to such
Borrower and the obligations under the Notes with respect to such Borrower shall
become immediately due and payable without declaration or advance notice of any
kind). The Agent shall promptly advise the relevant Borrower of any such
declaration, but failure to do so shall not impair the effect of such
declaration. If an Event of Default shall have occurred, the Agent may exercise
on behalf of itself and the Banks all rights and remedies available to it and
the Banks against the relevant Borrower under the Credit Documents or applicable
law.

                                  ARTICLE VIII

                                    THE AGENT

         8.1 Appointment and Authorization. Each Bank hereby irrevocably
(subject to Section 8.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Credit Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Credit
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Credit Document, the Agent shall not have any duties
or responsibilities, except those expressly set forth herein, nor shall the
Agent have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Credit Document or
otherwise exist against the Agent.

         8.2 Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Credit Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

         8.3 Liability of Agent. None of the Agent-Related Persons shall (i) be
liable to any of the Banks for any action taken or omitted to be taken by any of
them under or in connection with this Agreement or any other Credit Document or
the transactions contemplated hereby (except for its own gross negligence or
willful misconduct) or (ii) be responsible in any manner to any of the Banks for
any recital, statement, representation or warranty made by either Borrower or
any officer or agent thereof contained in this Agreement or in any other Credit
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement or any other Credit Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Credit
Document, or for any failure of a Borrower or any other party to any Credit
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Bank to ascertain or to inquire as
to the observance or performance of any of



                                       29




the agreements contained in or conditions of this Agreement or any other Credit
Document or to inspect the properties, books or records of a Borrower.

         8.4 Reliance by Agent. The Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel (including counsel to a
Borrower), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Credit Document unless it shall first receive such
advice or concurrence of the Majority Banks as it deems appropriate, and if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement or
any other Credit Document in accordance with a request or consent of the
Majority Banks and such request, and any action taken or failure to act pursuant
thereto shall be binding upon all of the Banks.

         8.5 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default, except with respect to defaults in
the payment of principal, interest and fees required to be paid to the Agent for
the account of the Banks, unless the Agent shall have received written notice
from a Bank or a Borrower referring to this Agreement, describing such Default
and stating that such notice is a "notice of default". The Agent will notify the
Banks of its receipt of any such notice. The Agent shall take such action with
respect to such Default as may be requested by the Majority Banks in accordance
with Article VII; provided, however, that unless and until the Agent has
received any such request, the Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default as
it shall deem advisable or in the best interest of the Banks.

         8.6 Credit Decision. Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it and that no
act by the Agent hereinafter taken, including any review of the affairs of the
Borrowers, shall be deemed to constitute any representation or warranty by any
Agent-Related Person to any Bank. Each Bank represents to the Agent that it has,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Borrowers,
and all applicable bank regulatory laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrowers hereunder. Each Bank also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Credit Documents and to
make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrowers. Except for notices, reports and other
documents expressly herein required to be furnished to the Banks by the Agent,
the Agent shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning the business,



                                       30




prospects, operations, property, financial and other condition or
creditworthiness of the Borrowers which may come into the possession of any of
the Agent-Related Persons.

         8.7 Indemnification of Agent. Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrowers and without limiting the obligation of the Borrowers to do so), pro
rata, from and against any and all Indemnified Liabilities; provided, however,
that no Bank shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified Liabilities resulting solely from such Person's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Bank shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Credit Document or any
document contemplated by or referred to herein, to the extent that the Agent is
not reimbursed for such expenses by or on behalf of the Borrowers. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Agent.

         8.8 Agent in Individual Capacity. BofA and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Borrowers and their
Affiliates as though BofA were not the Agent hereunder and without notice to or
consent of the Banks. The Banks acknowledge that, pursuant to such activities,
BofA or its Affiliates may receive information regarding the Borrowers or their
Affiliates (including information that may be subject to confidentiality
obligations in favor of the Borrowers) and acknowledge that the Agent shall be
under no obligation to provide such information to them. With respect to its
Loans, BofA shall have the same rights and powers under this Agreement as any
other Bank and may exercise the same as though it were not the Agent, and the
terms "Bank" and "Banks" include BofA in its individual capacity.

         8.9 Successor Agent. The Agent may, and at the request of the Majority
Banks shall, resign as Agent upon 30 days' notice to the Banks and the
Borrowers. If the Agent resigns under this Agreement, the Majority Banks shall
appoint from among the Banks a successor agent for the Banks, which successor
agent shall be subject to approval by the Borrowers. If no successor agent is
appointed prior to the effective date of the resignation of the Agent, the Agent
may appoint, after consulting with the Banks and the Borrowers, a successor
agent from among the Banks. Upon the acceptance of its appointment as successor
agent hereunder, such successor agent shall succeed to all the rights, powers
and duties of the retiring Agent and the term "Agent" shall mean such successor
agent, and the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article VIII and Sections 9.4 and 9.5 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement. If no successor agent has accepted appointment as Agent by
the date which is 30 days following a retiring Agent's notice of resignation,
the retiring Agent's resignation shall nevertheless thereupon become effective,
and the Banks shall perform all of the duties of the Agent hereunder until such
time, if any, as the Majority Banks appoint a successor agent as provided for
above.



                                       31




         8.10 Withholding Tax.

                  (a) On or prior to the date of execution and delivery of this
         Agreement in the case of each initial Bank, and on or prior to the date
         of the assignment pursuant to which it becomes a party to this
         Agreement in the case of an assignee Bank, and from time to time
         thereafter if requested by the Agent or either Borrower, any Bank that
         is a "foreign corporation, partnership or trust" within the meaning of
         the Code agrees with and in favor of the Agent and the Borrowers to
         deliver to the Agent and the Borrowers IRS Form 1001 and IRS Form W-8,
         two copies of IRS Form 4224, as appropriate, or any successor form or
         forms as may be required under the Code or other laws of the United
         States as a condition to exemption from, or reduction of, United States
         withholding tax.

         A Bank providing IRS Forms 1001 and W-8 shall also provide to the Agent
         and Borrowers properly completed IRS Forms 1001 and W-8 in each third
         succeeding calendar year during which interest may be paid under this
         Agreement. A Bank providing IRS Form 4224 shall also provide to the
         Agent and Borrowers two properly completed IRS Forms 4224 before the
         payment of interest is due in each succeeding taxable year of such Bank
         during which interest may be paid under this Agreement.

         Such Bank agrees to promptly notify the Agent and the Borrowers of any
         change in circumstances that would modify or render invalid any claimed
         exemption or reduction. If the IRS form provided by a Bank at the time
         such Bank first becomes a party to this Agreement indicates a United
         States withholding tax in excess of zero, withholding tax at such rate
         shall be considered excluded from Taxes and Other Taxes unless and
         until such Bank provides the appropriate form certifying that a lesser
         rate applies, whereupon withholding tax at such lesser rate only shall
         be considered excluded from Taxes and Other Taxes for the period
         governed by such form; provided, however, that, if at the date of an
         assignment pursuant to which an assignee becomes a party to this
         Agreement, the Bank assignor was entitled to payments under Section 3.1
         in respect of United States withholding tax with respect to interest
         paid at such date, then, to such extent, the term Taxes shall include
         United States withholding tax, if any, applicable with respect to the
         Bank assignee on such date. For any period with respect to which a Bank
         that is a "foreign corporation, partnership or trust" within the
         meaning of the Code has failed to provide the Agent and Borrowers with
         the appropriate IRS forms described above (other than if such failure
         is due to a change in law occurring subsequent to the date on which a
         Bank, or an assignee thereof, becomes a party to this Agreement), such
         Bank shall not be entitled to indemnification under Section 3.1 with
         respect to withholding taxes imposed by the United States; provided,
         however, that should a Bank become subject to withholding taxes because
         of its failure to deliver a form required hereunder, the Borrowers
         shall take such steps as the Bank shall reasonably request to assist
         the Bank to recover such Taxes.

                  (b) If any Bank claims exemption from or reduction of
         withholding tax under a United States tax treaty by providing IRS Form
         1001 and such Bank sells, assigns, grants a participation in or
         otherwise transfers all or part of the Obligations of a Borrower to
         such Bank, such Bank agrees to notify the Agent and such Borrower of
         the percentage amount in which it is no longer the beneficial owner of
         Obligations of such Borrower to



                                       32




         such Bank. To the extent of such percentage amount, the Agent and the
         relevant Borrower will treat such Bank's IRS Form 1001 as no longer
         valid.

                  (c) If any Bank claiming exemption from United States
         withholding tax by filing IRS Form 4224 with the Agent sells, assigns,
         grants a participation in or otherwise transfers all or part of the
         Obligations of a Borrower to such Bank, such Bank agrees to undertake
         sole responsibility for complying with the withholding tax requirements
         imposed by Sections 1441 and 1442 of the Code.

                  (d) If the IRS or any other Governmental Authority of the
         United States or other jurisdiction asserts a claim that the Agent or a
         Borrower did not properly withhold tax from amounts paid to or for the
         account of any Bank (because the appropriate form was not delivered,
         was not properly executed, or because such Bank failed to notify the
         Agent or the relevant Borrower of a change in circumstances which
         rendered the exemption from, or reduction of, withholding tax
         ineffective, or for any other reason), such Bank shall indemnify the
         Agent and the relevant Borrower fully for all amounts paid, directly or
         indirectly, by the Agent or the Borrower as tax or otherwise, including
         penalties and interest, and including any taxes imposed by any
         jurisdiction on the amounts payable to the Agent or the Borrower under
         this Section, together with all costs and expenses (including Attorney
         Costs). The obligation of the Banks under this subsection shall survive
         the payment of all Obligations and the resignation or replacement of
         the Agent.

                                   ARTICLE IX

                            MISCELLANEOUS PROVISIONS

         9.1 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Credit Document, and no consent with respect to any
departure by the Borrower therefrom, shall be effective unless the same shall be
in writing and signed by the Majority Banks (or by the Agent at the written
request of the Majority Banks) and the Borrowers and acknowledged by the Agent,
and then any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no such waiver, amendment or consent shall, unless in writing and signed by all
the Banks and the Borrowers and acknowledged by the Agent, do any of the
following:

                  (a) increase or extend the Commitments of any Bank (or
         reinstate any Commitment(s) terminated pursuant to Section 7.1);

         other Credit Document;

                  (c) reduce the principal of, or the rate of interest specified

                  (d) change the percentage of the Commitments or of the
         aggregate unpaid principal amount of the Loans which is required for
         the Banks or any of them to take any action hereunder; or

                  (e) amend this Section, Section 2.13, Section 6.12, the
         definition of "Asset Coverage Ratio" (or any defined term as it is used
         in such definition) or any provision herein providing for consent or
         other action by all Banks;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Majority Banks or all the
Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Credit Document and (ii) the Fee Letter may be amended,
or rights or privileges thereunder waived, in a writing executed by the parties
thereto.

         9.2 Notices.

                  (a) All notices, requests and other communications shall be in
         writing (including, unless the context expressly otherwise provides, by
         facsimile transmission, provided that any matter transmitted by a
         Borrower by facsimile (i) shall be immediately confirmed by a telephone
         call to the recipient at the number specified on Schedule III and (ii)
         shall be followed promptly by delivery of a hard copy original thereof)
         and mailed by certified mail return receipt requested postage prepaid,
         faxed or delivered to the address or facsimile number specified for
         notices on Schedule III, or, as directed to the Borrowers or the Agent,
         to such other address as shall be designated by such party in a written
         notice to the other parties, and as directed to any other party, at
         such other address as shall be designated by such party in a written
         notice to the Borrower and the Agent.

                  (b) All such notices, requests and communications shall, when
         transmitted by overnight delivery or faxed, be effective when delivered
         for overnight (next-day) delivery or transmitted in legible form by
         facsimile machine, respectively, or if mailed, upon the third Business
         Day after the date deposited into the U.S. mail by certified mail
         return receipt requested, or if delivered, upon delivery; provided that
         notices pursuant to Article II or VIII shall not be effective until
         actually received by the Agent.

                  (c) Any agreement of the Agent and the Banks herein to receive
         certain notices by telephone or facsimile is solely for the convenience
         and at the request of the Borrowers. The Agent and the Banks shall be
         entitled to rely on the authority of any Person purporting to be a
         Person authorized by a Borrower to give such notice, and the Agent and
         the Banks shall not have any liability to such Borrower or other Person
         on account of any action taken or not taken by the Agent or the Banks
         in reliance upon such telephonic or facsimile notice. The obligation of
         a Borrower to repay the Loans shall not be affected in any way or to
         any extent by any failure by the Agent and the Banks to receive written
         confirmation of any telephonic or facsimile notice or the receipt by
         the Agent and the Banks of a confirmation which is at variance with the
         terms understood by the Agent and the Banks to be contained in the
         telephonic or facsimile notice.



                                       34




         9.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay
in exercising, on the part of the Agent or any Bank, any right, remedy, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.

         9.4 Costs and Expenses. The relevant Borrower shall:

                  (a) whether or not the transactions contemplated hereby are
         consummated, pay or reimburse BofA (so long as it is the Agent, or if
         BofA is not the Agent, the Bank acting as successor Agent) (including
         in its capacity as Agent) within five Business Days after demand (i)
         each Borrower shall pay its pro rata portion of reasonable costs and
         expenses (based upon its respective net asset value as of the date of
         determination of any payment) in connection with the preparation,
         delivery, administration and execution of this Amended and Restated
         Credit Agreement, any Credit Document and any other documents prepared
         in connection herewith or therewith, and the consummation of the
         transactions contemplated hereby and thereby, including reasonable
         Attorney Costs incurred by BofA (so long as it is the Agent, or if BofA
         is not the Agent, the Bank acting as successor Agent) (including in its
         capacity as Agent) with respect thereto; and (ii) the Borrower
         responsible for a required amendment, supplement, waiver or
         modification (in each case whether or not consummated) of this
         Agreement, any Credit Document and any other document prepared in
         connection herewith or therewith shall pay all reasonable costs and
         expenses in connection therewith; provided, however, notwithstanding
         anything to the contrary in the foregoing, the responsibility of the
         relevant Borrower to reimburse BofA (so long as it is the Agent, or if
         BofA is not the Agent, the Bank acting as successor Agent) for Attorney
         Costs in connection with the development, preparation, delivery and
         execution of this amended and restated Agreement and such other
         documents and the consummation of such transactions shall be limited to
         the reasonable fees and disbursements of outside counsel to BofA (so
         long as it is the Agent, or if BofA is not the Agent, the Bank acting
         as successor Agent); and

                  (b) the Borrower responsible for a breach or violation of this
         Agreement or any Credit Document shall pay or reimburse the Agent, the
         Arranger and each Bank within five Business Days after demand for all
         costs and expenses (including Attorney Costs) incurred by them in
         connection with the enforcement, attempted enforcement or preservation
         of any rights or remedies under this Agreement or any other Credit
         Document during the existence of an Event of Default or after
         acceleration of the Loans (including in connection with any "workout"
         or restructuring regarding the Loans and including in any Insolvency
         Proceeding or appellate proceeding).

         9.5 Borrower Indemnification.

                  (a) Whether or not the transactions contemplated hereby are
         consummated, Van Kampen Prime Rate Income Trust shall indemnify and
         hold the Agent-Related Persons, and each Bank and each of its
         respective officers, directors, employees, counsel, agents and
         attorneys-in-fact (each, an "Indemnified Person"), harmless from and
         against any and all liabilities, obligations, losses, damages,
         penalties, settlement costs, actions,



                                       35




         judgments, suits, costs, charges, expenses and disbursements (including
         reasonable Attorney Costs) of any kind or nature whatsoever which may
         at any time (including at any time following repayment of the Loans and
         the termination, resignation or replacement of the Agent or replacement
         of any Bank) be imposed on, incurred by or asserted against any such
         Person in any way relating to or arising out of this Agreement or any
         Credit Document as a result of the activities of Van Kampen Prime Rate
         Income Trust, or the transactions contemplated hereby, the use of
         proceeds of any Loan or the Commitments or any action taken or omitted
         by any such Person under or in connection with any of the foregoing,
         including with respect to any investigation, litigation or proceeding
         (including any Insolvency Proceeding or appellate proceeding) related
         to or arising out of this Agreement or the Loans to Van Kampen Prime
         Rate Income Trust or the use of the proceeds thereof, whether or not
         any Indemnified Person is a party thereto (all the foregoing,
         collectively, the "Indemnified Liabilities"); provided that Van Kampen
         Prime Rate Income Trust shall not have an obligation hereunder to any
         Indemnified Person with respect to Indemnified Liabilities resulting
         from the gross negligence or willful misconduct of such Indemnified
         Person. The agreements in this Section shall survive payment of all
         other Obligations.

                  (b) Whether or not the transactions contemplated hereby are
         consummated, Van Kampen Senior Floating Rate Fund shall indemnify and
         hold the Agent-Related Persons, and each Bank and each of its
         respective officers, directors, employees, counsel, agents and
         attorneys-in-fact (each, an "Indemnified Person"), harmless from and
         against any and all liabilities, obligations, losses, damages,
         penalties, actions, judgments, suits, costs, charges, expenses and
         disbursements (including reasonable Attorney Costs) of any kind or
         nature whatsoever which may at any time (including at any time
         following repayment of the Loans and the termination, resignation or
         replacement of the Agent or replacement of any Bank) be imposed on,
         incurred by or asserted against any such Person in any way relating to
         or arising out of this Agreement or any Credit Document as a result of
         the activities of Van Kampen Senior Floating Rate Fund, or the
         transactions contemplated hereby, or any action taken or omitted by any
         such Person under or in connection with any of the foregoing, including
         with respect to any investigation, litigation or proceeding (including
         any Insolvency Proceeding or appellate proceeding) related to or
         arising out of this Agreement or the Loans to Van Kampen Senior
         Floating Rate Fund or the use of the proceeds thereof, whether or not
         any Indemnified Person is a party thereto (all the foregoing,
         collectively, the "Indemnified Liabilities"); provided that Van Kampen
         Senior Floating Rate Fund shall not have an obligation hereunder to any
         Indemnified Person with respect to Indemnified Liabilities resulting
         from the gross negligence or willful misconduct of such Indemnified
         Person. The agreements in this Section shall survive payment of all
         other Obligations.

                  (c) Promptly after receipt by an Indemnified Person under
         subsections (a) or (b) above of notice of the commencement of any
         action, such Indemnified Person shall, if a claim in respect thereof is
         to be made against the respective Borrower under such subsection,
         notify such Borrower in writing of the commencement thereof, but the
         omission so to notify such Borrower shall not relieve it from any
         liability which it may have to any Indemnified Person otherwise than
         under such subsection. In case any such action shall be brought against
         any Indemnified Person and it shall notify the respective



                                       36




         Borrower of the commencement thereof, the relevant Borrower or
         Borrowers, as applicable, shall be entitled to participate therein and,
         to assume the defense thereof, with counsel reasonably satisfactory to
         such Indemnified Person (who shall not, except with the consent of the
         Indemnified Person, be counsel to the relevant Borrower or Borrowers),
         and after notice from the relevant Borrower or Borrowers to such
         Indemnified Person of its election so to assume the defense thereof;
         provided that in no event shall any settlement or compromise of any
         such claims, actions or demands be made without the consent of the
         Indemnified Person, the consent of which shall not be unreasonably
         withheld; and provided, further, that the relevant Borrower or
         Borrowers shall not be required to reimburse the expenses of more than
         one counsel in any jurisdiction unless the Indemnified Parties shall
         determine in their sole discretion that their interests may differ.

                  (d) The agreements in this Section 9.5 shall survive payment
         of all other Obligations. The obligations under 9.5(a) and 9.5(b)
         hereof shall be without duplication.

         9.6 Payments Set Aside. To the extent that a Borrower makes a payment
to the Agent or the Banks, or the Agent or the Banks exercise their right of
set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

         9.7 Successors and Assigns.

                  (a) The provisions of this Agreement shall be binding upon and
         shall inure to the benefit of the Borrowers, the Agent and the Banks
         and their respective successors and assigns, except that a Borrower may
         not assign or otherwise transfer any of its rights under this Agreement
         without the prior written consent of the Banks; provided that the Banks
         hereby agree that (i) they each consent to any transfer or assignment
         made to another Person pursuant to Section 6.11(b) so long as all of
         the conditions in the proviso in Section 6.11(b) are met; (ii) the
         Banks further agree that any transfer or assignment made pursuant to
         Section 6.11(b) shall not itself be deemed to be a rescission,
         amendment or modification of any "fundamental" investment policy under
         Section 6.7(a) or a violation of Section 6.7(b); and (iii) the Banks
         agree to release the relevant original Borrower from all liability
         hereunder.

                  (b) The Loans are being made by the Banks in the ordinary
         course of their business and not with a view toward distribution, it
         being understood that each Bank may sell participations and assignments
         in its Commitments and the Loans (other than Swing Loans) as provided
         herein. Any Bank may, upon payment by such Bank to the Agent of an
         assignment fee of $3,500, at any time assign, subject to the relevant
         Borrower's consent, which consent shall not be unreasonably withheld,
         to one or more banks (as



                                       37




         defined in Section 2(a)(5) of the Act) (each of which shall have a net
         worth of at least $500,000,000 (or the equivalent thereof in another
         currency)) not an affiliate (as defined in the Act) of or an affiliate
         (as defined in the Act) of such an affiliate of either of the Borrowers
         or Van Kampen Investment Advisory Corp. (each an "Assignee") all, or a
         proportionate part of all, of its rights under this Agreement and the
         relevant Borrower's Notes in a minimum amount of $25,000,000; provided
         that the relevant Borrower may continue to deal solely and directly
         with the Bank in connection with any interest assigned until such
         Borrower receives written notice of assignment, the address of the
         assignee and such Borrower consents. Any Bank may at any time grant to
         one or more financial institutions (each of which shall have a net
         worth of at least $500,000,000 (or the equivalent thereof in another
         currency)) not an affiliate (as defined in the Act) of either of the
         Borrowers or Van Kampen Investment Advisory Corp. (each a
         "Participant") participating interests in its Commitments or any or all
         of its Loans. In the event of any such grant by a Bank of a
         participating interest to a Participant, whether or not upon notice to
         the relevant Borrower, such Bank shall remain responsible for the
         performance of its obligations hereunder, and such Borrower shall
         continue to deal solely and directly with such Bank in connection with
         the Bank's rights and obligations under this Agreement. Any agreement
         pursuant to which such Bank may grant such a participating interest
         shall provide that the Bank shall retain the sole right and
         responsibility to enforce the obligations of the relevant Borrower
         hereunder, including, without limitation, the right to approve any
         amendment, modification or waiver of any provision of this Agreement;
         provided that such participation agreement may provide that such Bank
         will not agree to any modification, amendment or waiver of this
         Agreement (i) which increases or decreases the Commitments of the Bank,
         (ii) reduces the principal of or rate of interest on any Loan or fees
         hereunder or (iii) postpones the date fixed for any payment of
         principal of or interest on any Loan or any fees hereunder without the
         consent of the Participant. The relevant Borrower agrees that each
         Participant shall, to the extent provided in its participation
         agreement, be entitled to the benefits of Article III hereof with
         respect to its participating interest subject to clause (d) below and
         subject to compliance with Section 8.10 by the participant as if it
         were a Bank.

                  (c) Any Bank may at any time assign all or any portion of its
         rights under this Agreement and the Notes to a Federal Reserve Bank. No
         such assignment shall release such Bank from its obligations hereunder.

                  (d) No Assignee, Participant or other transferee of a Bank's
         rights shall be entitled to receive any greater payment under Section
         3.1 and Section 3.3 hereof than such Bank would have been entitled to
         receive with respect to the rights transferred, unless such transfer is
         made with the relevant Borrower's prior written consent or at a time
         when the circumstances giving rise to such greater payment did not
         exist.

         9.8 Confidentiality. Each Bank agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all written information identified as
"confidential" or "secret" by any Borrower and provided to it by or on behalf of
such Borrower, or by the Agent on a Borrower's behalf, under this Agreement or
any other Credit Document, and neither it nor any of its Affiliates shall use
any such information other than in connection with or in enforcement of this
Agreement and the other



                                       38




Credit Documents, except to the extent such information (i) was or becomes
generally available to the public other than as a result of disclosure by the
Bank or (ii) was or becomes available on a non-confidential basis from a source
other than a Borrower; provided that such source is not bound by a
confidentiality agreement with a Borrower known to the Bank; provided, however,
that any Bank may disclose such information (A) at the request or pursuant to
any requirement of any Governmental Authority to which the Bank is subject or in
connection with an examination of such Bank by any such authority; (B) pursuant
to subpoena or other legal process; (C) when required to do so in accordance
with the provisions of any applicable Requirement of Law; (D) to the extent
reasonably required in connection with any litigation or proceeding to which the
Agent, any Bank or their respective Affiliates may be party; (E) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Credit Document; (F) to persons (including Affiliates) that
perform credit administration and review processes for such Bank and to such
Bank's independent auditors and other professional advisors; (G) to any
Participant or Assignee, actual or potential; provided that such Person agrees
in writing to keep such information confidential to the same extent as required
by the Banks hereunder; (H) as to any Bank or its Affiliate, as expressly
permitted under the terms of any other document or agreement regarding
confidentiality to which a Borrower is party or is deemed party with such Bank
or such Affiliate; and (I) to its Affiliates; provided that each Bank shall
require its Affiliates to agree to comply with the provisions of Section 9.9;
and provided further that in the case of clauses (B), (C) and (D), such Bank
shall use reasonable efforts to notify the relevant Borrower promptly of any
requests to disclose such information so that the Borrower may seek a protective
order or other appropriate remedy.

         9.9 Set-off.

                  (a) In addition to any rights and remedies of the Banks
         provided by law, but subject to Section 9.9(b), if, as to a Borrower,
         an Event of Default exists and is continuing or the Loans have been
         accelerated, each Bank is authorized at any time and from time to time,
         without prior notice to such Borrower (any such notice being waived by
         such Borrower 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 by, and other indebtedness at
         any time owing by, such Bank to or for the credit or the account of
         such Borrower against any and all Obligations of such Borrower owing to
         such Bank, now or hereafter existing, irrespective of whether or not
         the Agent or such Bank shall have made demand under this Agreement or
         any Credit Document and although such Obligations may be contingent or
         unmatured; provided that any such appropriation and application shall
         be subject to the provisions of Section 2.13. Each Bank agrees promptly
         to notify the relevant Borrower and the Agent after any such set-off
         and application made by such Bank; provided, however, that the failure
         to give such notice shall not affect the validity of such set-off and
         application.

                  (b) Notwithstanding the foregoing, in no event shall any Bank
         have any right to set off or otherwise apply any deposits of any kind
         at any time held by any such Bank to the extent that such Bank holds
         such deposits as a Borrower's custodian or agent. Without limiting the
         foregoing, in no event shall State Street Bank and Trust Company set
         off or otherwise apply any deposits of any kind at any time held by
         State Street Bank and Trust Company pursuant to any Custodian Contract

BANKS AND THE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE
TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE

references in the Credit Documents or other similar documents to "Credit
Agreement" or words of like import shall refer to this Agreement. The execution,
delivery and effectiveness of this Agreement shall not, except as expressly
provided herein, operate as a waiver of any right, power or remedy of the Banks

provision of the Credit Documents.

         9.21 Facsimile Execution. One or more executed counterparts of this
Agreement or any document or instrument related hereto may be delivered by
facsimile, with the intention that



                                       41




such counterparts have the same effect as an original executed counterpart
hereof or thereof. Any party hereto delivering an executed counterpart of this
Agreement or any related document or instrument by facsimile shall promptly
provide an original of such executed counterpart to the Agent.

         9.22 Syndication Agent; Documentation Agent. The parties hereto
acknowledge that each of the Syndication Agent and the Documentation Agent has
been designated as such for purposes of convenience only and that neither the
Syndication Agent nor the Documentation Agent shall have any duties or
responsibilities, except those that may be expressly set forth in a separate
written instrument signed by the Syndication Agent or Documentation Agent, as
the case may be, or any fiduciary relationship with any Bank and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or otherwise exist against the Syndication Agent or
the Documentation Agent, as the case may be.
