                                  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 each of the
Borrowers from time to time on any Business Day during the period from the
Closing Date to the Revolving Termination Date, in an aggregate amount for both
Borrowers not to exceed at any time outstanding the amount set forth on Schedule
2.1 (such amount as the same may be reduced or increased under Section 2.5 or as
a result of one or more assignments under Section 10.9, 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 combined Commitments. Within the limits of each Bank's Commitment,
and subject to the other terms and conditions hereof, each Borrower may borrow
under this Section 2.1, prepay under Section 2.6 and reborrow under this Section
2.1.

         2.2 Loan Accounts. (a) The Loans made by each Bank shall be evidenced
by one or more loan accounts or records maintained by such Bank in the ordinary
course of business. The loan accounts or records maintained by the Agent and
each Bank shall be presumptively correct absent manifest error of the amount of
the Loans made by the Banks to each Borrower and the interest and payments
thereon. Any failure so to record or any error in doing so shall not, however,
limit or otherwise affect the obligation of such Borrower hereunder to pay any
amount owing with respect to its Loans.

             (b) Upon the request of any Bank made through the Agent, the Loans
         made by such Bank may be evidenced by one or more Notes, instead of
         loan accounts. Each such Bank shall endorse on the schedules annexed to
         its Note(s) the date, amount and maturity of each Loan made by it and
         the amount of each payment of principal made by the applicable Borrower
         with respect thereto. Each such Bank is irrevocably authorized by each
         Borrower to endorse its Note(s) and each Bank's record shall be
         presumptively correct absent manifest error; 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 such Borrower hereunder or under any such Note to
         such Bank.

         2.3 Procedure for Borrowing. (a) Each Borrowing shall be made upon the
irrevocable written notice of a Borrower delivered to the Agent in the form of a
Notice of Borrowing (which notice must be received by the Agent prior to 11:00
a.m. (Charlotte time) (i) three Business Days prior to the requested Borrowing
Date, in the case of Offshore Rate Loans; and (ii) on the requested Borrowing
Date, in the case of Base Rate Loans and Federal Funds Rate Loans, specifying:

                    (A)  the applicable Borrower;

                    (B)  the amount of the Borrowing, which shall be in an
               aggregate minimum amount of $5,000,000 or any multiple of
               $1,000,000 in excess thereof;

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

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

                    (E) the duration of the Interest Period applicable to such
               Loans included in such notice. If the Notice of Borrowing fails
               to specify the duration of the Interest Period for any Borrowing
               comprised of Offshore Rate Loans, such Interest Period shall be
               three months.


               (b) The Agent will promptly notify each Bank of its receipt of
         any Notice of Borrowing 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 applicable
         Borrower at the Agent's Payment Office by 1:00 p.m. (Charlotte time) on
         the Borrowing Date requested by the applicable Borrower in funds
         immediately available to the Agent. The proceeds of all such Loans will
         then be made available to the applicable Borrower by the Agent by wire
         transfer in accordance with written instructions provided to the Agent
         by the applicable Borrower of like funds as received by the Agent.

               (d) After giving effect to any Borrowing, there may not be more
         than five different Interest Periods in effect.

         2.4 Conversion and Continuation Elections. (a) Each Borrower may, upon
irrevocable written notice to the Agent in accordance with Section 2.4(b):

                   (i) elect, as of any Business Day, in the case of Base Rate
         Loans or Federal Funds Rate Loans, or as of the last day of the
         applicable Interest Period, in the case of Offshore Rate Loans, to
         convert any such Loans (or any part thereof in an amount not less than
         $5,000,000, or that is in an integral multiple of $1,000,000 in excess
         thereof) into Loans of any other Type; or

                                       18
<PAGE>   26



                  (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 not less than $5,000,000, or that
         is in 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 $5,000,000, such Offshore Rate Loans shall
automatically convert into Base Rate Loans, and on and after such date the right
of the applicable Borrower to continue such Loans as, and convert such Loans
into, Offshore Rate Loans shall terminate.

               (b) The applicable Borrower shall deliver a Notice of Conversion/
         Continuation to be received by the Agent not later than 11:00 a.m.
         (Charlotte 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 converted into
         Base Rate Loans or Federal Funds Rate Loans, specifying:


                    (A)  the proposed Conversion/Continuation Date;

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

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

                    (D)  in the case of conversions into Offshore Rate Loans,
         the duration of the requested Interest Period.

               (c)  If upon the expiration of any Interest Period applicable to
         Offshore Rate Loans, a Borrower has failed to select timely a new
         Interest Period to be applicable to such Offshore Rate Loans, or if any
         Default or Event of Default then exists, the applicable Borrower shall
         be deemed to have elected to convert such Offshore Rate Loans into Base
         Rate Loans effective as of the expiration date of such Interest Period.

               (d)  The Agent will promptly notify each Bank of its  receipt of
         a Notice of Conversion/Continuation, or, if no timely notice is
         provided by the applicable Borrower, the Agent will promptly notify
         each Bank of the details of any automatic conversion. 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.

               (e)  Unless the Majority Banks otherwise agree, during the
         existence of a Default or Event of Default, the Borrowers may not elect
         to have Loans converted into or continued as an Offshore Rate Loan.

                                       19
<PAGE>   27



             (f) After giving effect to any conversion or continuation of
         Loans, there may not be more than five different Interest Periods in
         effect.

         2.5 Voluntary Termination or Reduction of Commitments; Increase of
Commitments.

             (a) Any Borrower may, upon not less than three (3) Business Days'
         prior 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 combined Commitments then in effect. Once
         reduced in accordance with this Section, the Commitments may not be
         increased. Any reduction of the Commitments 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 reduction or termination of
         Commitments, shall be paid on the effective date of such reduction or
         termination.

             (b) Increases in Commitments.

                 (i)   If no Default or Event of Default has occurred and is
             continuing, any Borrower may, at any time prior to the Revolving
             Termination Date, request an increase in the aggregate Commitments,
             by giving written notice to the Agent and each Bank (each such
             notice an "Increase Request"). Concurrently with delivering an
             Increase Request, such Borrower may seek additional commitments
             from other financial institutions ("New Bank(s)"). An Increase
             Request may request an increase in the aggregate Commitments of at
             least $5,000,000 but not more than $50,000,000; provided, that in
             no event shall the aggregate Commitments of the Banks (including
             New Banks) hereunder exceed $200,000,000 at any time. Each Bank
             may, in its sole and absolute discretion, commit to increase its
             Commitment by all or a part of the increase requested in the
             Increase Request by delivering to such Borrower and the Agent a
             commitment valid for a period of 30 days ("Commitment Increase
             Notice") to such effect, which Commitment Increase Notice shall
             refer to this Section 2.5(b)(i) and which shall be given no later
             than 10 Business Days after the date of the Increase Request (the
             period between the date of the Increase Request and the 10 Business
             Day deadline for response being referred to as the "Consent
             Period"). The existing Commitment of any Bank shall not be
             increased in connection with an Increase Request if such Bank (x)
             by notice ("Decline Notice") declines to increase its Commitment
             during the Consent Period or (y) fails to respond to the Borrower
             and the Agent within the Consent Period (each such Bank giving a
             Decline Notice or failing to respond on or before the expiration of
             the Consent Period being called a "Declining Bank" and each other
             Bank being called an "Increasing Bank").


                 (ii) Upon expiry of the Consent Period (or sooner if all
             existing Banks and New Banks respond sooner), if the commitments of
             the Increasing Banks
                                       20

<PAGE>   28



             specified in their respective Commitment Increase Notices and the
             New Bank(s) in their commitment letters equal or exceed the
             Increase Request, the Agent shall allocate such commitments up to
             the amount specified in the Increase Request to the Increasing
             Banks and New Bank(s) based on the ratio of each Increasing Bank's
             commitment specified in its Commitment Increase Notice (or New Bank
             in its commitment letter) to the aggregate of all commitments of
             the Increasing Banks specified in the Commitment Increase Notices
             and New Bank(s) in their commitment letters.

                 (iii) Upon expiry of the Consent Period, if the commitments of
             the Increasing Banks specified in their respective Commitment
             Increase Notices and the New Bank(s) in their commitment letters
             are less than the Increase Request, the Borrowers may agree to
             accept such commitments from the Increasing Banks and New Bank(s).
             Upon expiry of the Consent Period (or sooner if all existing Banks
             and New Banks respond sooner), the Borrowers may add New Bank(s)
             with commitments up to the amount specified in their commitment
             letters; provided, that (A) no Default shall have occurred and be
             continuing, (B) the aggregate amount of Commitments plus increases
             in Increasing Bank existing Commitments and New Bank commitments
             does not exceed $200,000,000, (C) any such New Bank assumes all the
             rights and obligations of a "Bank" hereunder pursuant to accession
             documentation as the Agent shall specify and described below and
             (D) such New Bank is reasonably satisfactory to the Agent. If the
             Borrowers do accept such commitments, the Agent shall allocate such
             commitments to each of the Increasing Banks and New Bank(s) based
             on the ratio of its commitment specified in its Commitment Increase
             Notice or commitment letter to the aggregate of all commitments of
             the Increasing Banks and New Bank(s) specified in their Commitment
             Increase Notices and commitment letters.

                 (iv) Upon allocation of the increased commitments to the
             Increasing Banks and/or New Bank(s), the Borrowers shall deliver
             such documentation as the Agent may reasonably require to evidence
             the Borrowers' authority to incur the increased obligations
             hereunder, and if requested by the Increasing Banks and/or New
             Banks, replacement Notes to the Increasing Banks and/or new notes
             to the New Bank(s) reflecting the Commitment of each Increasing
             Bank and New Bank. Such new and replacement notes, if any, shall be
             deemed to constitute a "Note" or "Notes" hereunder for all purposes
             and such new and increased commitments shall constitute a
             "Commitment" or "Commitments" hereunder for all purposes. The Agent
             shall promptly provide each of the Banks a revised Schedule 1.1
             reflecting the Commitments of the Banks.

                 (v) Any New Bank may become a "Bank" under this Agreement by
             executing and delivering to the Borrowers and the Agent an
             Accession Agreement (an "Accession Agreement") in substantially the
             form of Exhibit G hereto and such related documentation as shall be
             reasonably satisfactory in form and substance to

                                       21
<PAGE>   29


             the Agent, pursuant to which such New Bank shall assume the rights,
             privileges, duties and obligations of a "Bank" hereunder. Upon the
             effectiveness of any such Accession Agreement and related
             documentation, the New Bank shall become a "Bank" for all purposes
             of this Agreement having the Commitments specified in such
             Accession Agreement. The Agent shall promptly provide a copy of
             each Accession Agreement to each of the Banks.

                 (vi) Upon the effectiveness of any increase pursuant to this
             Section 2.5(b) of the aggregate Commitments and any resulting
             adjustment in a Pro Rata Share, the Banks and the New Banks will
             purchase from each other and sell to each other outstanding Loans
             sufficient to cause the outstanding Loans of each Bank and New Bank
             to equal its Pro Rata Share (as so adjusted) of the aggregate
             outstanding Loans. If any Bank shall suffer a loss or incur an
             expense as a result of the effectiveness of such purchase or sale
             being during an Interest Period, the applicable Borrower shall
             reimburse such Bank the amount of such loss or expense. Each such
             Bank shall furnish such Borrower with a certificate setting forth
             the basis for determining the amount to be paid to it hereunder.

         2.6 Optional Prepayments. Subject to Section 3.4, each Borrower
may, at any time or from time to time, upon not less than one Business Day's
irrevocable notice to the Agent, ratably prepay Loans in whole or in part, in
minimum amounts of $5,000,000 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. 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. If such notice is given by a Borrower, such Borrower shall make such
prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein, together with accrued interest to each
such date on the amount prepaid and any amounts required pursuant to Section
3.4.

         2.7 Repayment. Each Borrower shall repay to the Banks on the Revolving
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 Offshore Rate, the Federal Funds Rate or the Base Rate, as the case
may be (and subject to each Borrower's right to convert to other Types of Loans
under Section 2.4), plus, in the case of Offshore Rate Loans and Federal Funds
Rate Loans, the Applicable Margin.

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

                                       22

             (c) Notwithstanding subsection (a) of this Section, while any
         Event of Default exists or after acceleration, the defaulting Borrower
         shall pay interest (after as well as before entry of judgment thereon
         to the extent permitted by law) on the principal amount of all its
         outstanding Loans, at a rate per annum which is determined by adding 2%
         per annum to the rate of interest then in effect for such Loans;
         provided, however, that, on and after the expiration of any Interest
         Period applicable to any Offshore Rate Loan outstanding on the date of
         occurrence of such Event of Default or acceleration, the principal
         amount of such Loan shall, during the continuation of such Event of
         Default or after acceleration, bear interest at a rate per annum equal
         to the Base Rate plus 2%.

             (d) Anything herein to the contrary notwithstanding, the
         obligations of the Borrowers to any Bank hereunder shall be subject to
         the limitation that payments of 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
         Borrowers shall pay such Bank interest at the highest rate permitted by
         applicable law.

         2.9 Fees. (a) Arrangement, Agency Fees. The Borrowers shall pay an
arrangement fee to the Arranger for the Arranger's own account, and shall pay an
agency fee to the Agent for the Agent's own account, as required by the letter
agreement ("Fee Letter") among the Borrowers, the Arranger and Agent dated July
12, 2000.

             (b) Facility Fees. The Borrowers jointly and severally agree to
         pay to the Agent for the account of each Bank a facility fee on the
         average daily amount of such Bank's Commitment, computed on a quarterly
         basis in arrears on the last Business Day of each calendar quarter for
         that quarter as calculated by the Agent, equal to the Applicable
         Facility Fee Rate per annum. Such facility fee shall accrue from the
         date hereof to the Revolving Termination Date and shall be due and
         payable quarterly in arrears on the last Business Day of each calendar
         quarter commencing on September 30, 2000 through the Revolving
         Termination Date (or, if later, the date of repayment of all the
         Loans), with the final payment to be made on the Revolving Termination
         Date (or, if later, the date of repayment of all the Loans); provided
         that, in connection with any reduction or termination of Commitments
         under Section 2.5, the accrued facility fee calculated for the period
         ending on such date shall also be paid on the date of such reduction or
         termination, with the following quarterly payment being calculated on
         the basis of the period from such reduction or termination date to such
         quarterly payment date. The facility 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. It is acknowledged and agreed that if the Loans and
         facility fees are not paid on the Revolving Termination Date, facility
         fees after the Revolving Termination Date shall accrue on the amount of
         outstanding Loans (as opposed to Commitments) and shall be paid
         concurrently with the repayment of the Loans.

                                       23
<PAGE>   31


             (c) Utilization Fees. The Borrowers jointly and severally agree to
         pay to the Agent for the account of each Bank a utilization fee on the
         average daily amount of such Bank's Loans, computed on a quarterly
         basis in arrears on the last Business Day of each calendar quarter for
         that quarter as calculated by the Agent for each day on which the
         outstanding principal amount of the Loans plus the "Loans" under the
         Other Credit Agreement exceeds 50% of the then applicable Commitments
         plus the "Commitments" under the Other Credit Agreement, equal to the
         Applicable Utilization Fee Rate per annum. Such utilization fee shall
         accrue from the date hereof to the Revolving Termination Date and shall
         be due and payable quarterly in arrears on the last Business Day of
         each calendar quarter commencing on September 30, 2000 through the
         Revolving Termination Date (or, if later, the date of repayment of all
         the Loans), with the final payment to be made on the Revolving
         Termination Date (or, if later, the date of repayment of all the
         Loans); provided that, in connection with any reduction or termination
         of Commitments under Section 2.5, the accrued utilization fee
         calculated for the period ending on such date shall also be paid on the
         date of such reduction or termination, with the following quarterly
         payment being calculated on the basis of the period from such reduction
         or termination date to such quarterly payment date. The utilization
         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
for Base Rate Loans when the Base Rate is determined by Bank of America's "prime
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 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-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 Borrowers and the Banks in the absence of
         manifest error. The Agent will, at the request of either Borrower or
         any Bank, deliver to such Borrower or the 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 by the Borrowers. (a) All payments to be made by the
Borrowers shall be made without set-off, recoupment or counterclaim. Except as
otherwise expressly provided herein, all payments by the Borrowers 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 3:00
p.m. (Charlotte 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 3:00 p.m. (Charlotte time) shall be
deemed to have been received on the following Business Day and any applicable
interest or fee shall continue to accrue.

                                       24
<PAGE>   32


              (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 the applicable Borrower
         prior to the date on which any payment is due to the Banks that the
         applicable Borrower will not make such payment in full as and when
         required, the Agent may assume that the applicable 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 the
         applicable 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 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 applicable 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 applicable 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
applicable Borrower of such failure to fund and, upon demand by the Agent, the
applicable Borrower shall pay such amount to the Agent for the Agent's account
within two Business Days, 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.

                                       25
<PAGE>   33



         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 (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 Borrowers agree
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, but subject to Section 10.11) with respect to such
participation as fully as if such Bank were the direct creditor of the Borrowers
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 Extension of Scheduled Revolving Termination Date. The Scheduled
Revolving Termination Date shall be subject to extension, as set forth in this
Section.

              (a) No earlier than 60 days nor later than 45 days prior to the
         then Scheduled Revolving Termination Date, the Borrowers may, by
         delivery of a written request to the Agent, irrevocably request that
         each Bank extend for an additional 364 day period (such period to
         commence on the day immediately following the then Scheduled Revolving
         Termination Date) the Scheduled Revolving Termination Date.

              (b) The Agent shall, promptly after receipt of any such extension
         request notify each Bank thereof.

              (c) Each Bank shall, within 15 days of receipt of the notice
         described in clause (b), notify the Agent whether or not it consents to
         the request of the Borrowers set forth in such extension request, such
         consent to be in the sole discretion of such Bank. If any Bank does not
         so notify the Agent of its decision within such 15 day period (such 15
         day period, herein the "Consent Period."), such Bank shall be deemed
         not to have consented to such request of the Borrowers.

              (d) The Agent shall promptly notify the Borrowers whether the
         Banks have consented to such request, but in any event by the last day
         of the Consent Period. If the Agent does not so notify the Borrowers
         within 5 days prior to the then existing Scheduled Revolving
         Termination Date, the Agent shall be deemed to have notified the
         Borrowers that the Banks have not consented to the Borrowers' request.

                                       26
<PAGE>   34


              (e) Each Bank that elects not to extend the Scheduled Revolving
         Termination Date relating to such Bank's Commitment upon the expiration
         of the then effective Scheduled Revolving Termination Date or that
         fails to so notify the Agent of such consent (a "Non-Consenting Bank")
         hereby agrees that if, on or prior to the then effective Scheduled
         Revolving Commitment Date, any other Bank or other financial
         institution acceptable to the Borrowers and the Agent offers to
         purchase such Non-Consenting Bank's Pro Rata Share of the Commitments
         for a purchase price equal to the sum of all amounts then owing with
         respect to the Loans and all other amounts accrued for the account of
         such Non-Consenting Bank, such Non-Consenting Bank will assign, sell
         and transfer on the then effective Scheduled Revolving Termination Date
         all of its right, title, interest and obligations with respect to the
         foregoing to such other Bank or financial institution pursuant to the
         terms of Section 10.9 and the fee payable pursuant to Section 10.9
         shall be payable by such assignee.

              (f) On the date that would have been the Scheduled Revolving
         Termination Date had the Scheduled Revolving Termination Date not been
         extended pursuant to the terms of this Section, the Loans of any
         Non-Consenting Bank that were not purchased pursuant to clause (e) will
         mature and be due and payable on the then Scheduled Revolving
         Termination Date, and the Commitment of such Non-Consenting Bank will
         thereupon terminate. On such Scheduled Revolving Termination Date, the
         aggregate Commitments will be automatically reduced by an amount equal
         to the Commitments of the Non-Consenting Banks that were not purchased
         pursuant to clause (e). The Pro Rata Shares of the remaining Banks
         which have consented to an extension of their Commitments hereunder
         shall be adjusted accordingly by the Agent.

         Notwithstanding anything to the contrary contained in this Section, the
Scheduled Revolving Termination Date of those Banks consenting to such an
extension shall not be extended for an additional 364 day period unless Banks
whose Commitments exceed a majority of the Commitments, agree to such an
extension.

                                  ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.1 Taxes. (a) Any and all payments by the Borrowers to each Bank or
the Agent under this Agreement and any other Loan Document shall be made free
and clear of, and without deduction or withholding for any Taxes. In addition,
the Borrowers shall pay all Other Taxes.

             (b) The Borrowers agree to indemnify and hold harmless the
         applicable Bank and the Agent for the full amount of Taxes or Other
         Taxes (including any Taxes or Other Taxes imposed by any jurisdiction
         on amounts payable under this Section) paid by such Bank or the Agent
         and any liability (including penalties, interest, additions to tax and
         expenses) arising therefrom or with respect thereto, whether or not
         such Taxes or Other Taxes were correctly or legally asserted; provided,
         however, that any claim under this Section 3.1 must

                                       27
<PAGE>   35



         be reasonable. Payment under this indemnification shall be made within
         30 days after the date the Bank or the Agent makes written demand
         therefor, stating in reasonable detail the basis for its
         indemnification claim.

              (c) If a Borrower shall be required by law to deduct or withhold
         any 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 had no such deductions
         or withholdings been made;

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

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

             (d) Within 30 days after the date of any payment by a Borrower of
         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 reasonably satisfactory to the Agent.

             (e) If a Borrower is required to pay additional amounts to any
         Bank or the Agent pursuant to subsection (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.

         3.2 Illegality. (a) If any Bank 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 such Bank or its applicable Lending Office to make
Offshore Rate Loans, then, on notice thereof by such Bank to the Borrowers
through the Agent, any obligation of that Bank to make Offshore Rate Loans shall
be suspended until such Bank notifies the Agent and the Borrowers that the
circumstances giving rise to such determination no longer exist.

            (b) If a Bank determines that it is unlawful to maintain any
         Offshore Rate Loan, the Borrowers shall, upon its receipt of notice of
         such fact and demand from such Bank (with a copy to the Agent), prepay
         in full such Offshore Rate Loans of that Bank then outstanding,

                                       28
<PAGE>   36


         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. If a Borrower is required to so
         prepay any Offshore Rate Loan, then concurrently with such prepayment,
         such Borrower may borrow from the affected Bank, in the amount of such
         repayment, a Base Rate Loan or a Federal Funds Rate Loan.

            (c)  If a Bank makes a determination under this Section 3.2, 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 illegality, if such change in the
         judgment of such Bank is not otherwise disadvantageous to such Bank.


         3.3 Increased Costs and Reduction of Return. (a) If any Bank determines
that, due to either (i) the introduction of or any change (other than any change
by way of imposition of or increase in reserve requirements included in the
calculation of the Offshore Rate or in the interpretation of any law or
regulation or (ii) the compliance by that Bank with any guideline or request
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 of agreeing
to make or making, funding or maintaining any Offshore Rate Loans, then the
Borrowers shall be liable for, and shall from time to time, upon 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; provided, however, the Borrowers shall not be required to
pay any such expense if the applicable Bank shall not notify the Borrowers of
such expense within 180 days of such Bank being aware of its incurrence.

             (b)  If any Bank shall have 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 the Bank (or its Lending
         Office) or any corporation controlling the Bank with any Capital
         Adequacy Regulation, affects or would affect the amount of capital
         required or expected to be maintained by the Bank or any corporation
         controlling the 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) determines that the amount of such capital
         is increased as a consequence of its Commitment[s], loans, credits or
         obligations under this Agreement, then, upon demand of such Bank to the
         Borrowers through the Agent, the Borrowers shall pay to the Bank, from
         time to time as specified by the Bank, additional amounts sufficient to
         compensate the Bank for such increase; provided, however, the Borrowers
         shall not be required to pay any such expense if the applicable Bank
         shall not notify the Borrowers of such expense within 180 days of such
         Bank being aware of its incurrence.

                                       29
<PAGE>   37


             (c)  If a Borrower is required to pay additional amounts to any
         Bank or the Agent pursuant to this Section 3.3, 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 Borrowers which may
         thereafter accrue, if such change in the judgment of such Bank is not
         otherwise disadvantageous to such Bank.

         3.4 Funding Losses. Each Borrower shall reimburse each Bank and hold
each Bank harmless from any loss or expense which the Bank may 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
         Notice of Borrowing or a Notice of Conversion/ Continuation;

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

             (d)  the prepayment or other payment (including after acceleration
         thereof) of an Offshore Rate Loan on a day that is not the last day of
         the relevant Interest Period; or

             (e)  the automatic conversion under Section 2.4 of any Offshore
         Rate Loan to a Base Rate Loan on a day that is not the last day of the
         relevant Interest Period; 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 the Borrowers to the Banks under this
         Section and under Section 3.3(a), each 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 Offshore Base
         Rate 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 the 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 the Banks of funding such Loan, the
Agent will promptly so notify the Borrowers and each Bank. Thereafter, the
obligation of the Banks to make or maintain Offshore Rate Loans hereunder shall
be suspended until the Agent revokes such notice in writing. Upon receipt of
such notice, each Borrower may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it. If such Borrower does not revoke
such Notice, the Banks shall make, convert or continue the Loans, as proposed by
such Borrower, in the

                                       30
<PAGE>   38


amount specified in the applicable notice submitted by such Borrower, but such
Loans shall be made, converted or continued as Base Rate Loans.

         3.6 Certificates of Banks. Any Bank claiming reimbursement or
compensation under this Article III shall deliver to the Borrowers (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 presumptively
correct and binding on the Borrowers in the absence of manifest error.

         3.7 Substitution of Banks. Upon the receipt by the Borrowers from any
Bank (an "Affected Bank") of a claim for compensation under Section 3.1 or 3.3,
or any determination of illegality under Section 3.2, the Borrowers may: (i)
request the Affected Bank to use its best efforts to obtain a replacement bank
or financial institution satisfactory to the Borrowers to acquire and assume all
or a ratable part of all of such Affected Bank's Loans and Commitment (a
"Replacement Bank"); (ii) request one more of the other Banks to acquire and
assume all or part of such Affected Bank's Loans and Commitment; or (iii)
designate a Replacement Bank. Any such designation of a Replacement Bank under
clause (i) or (iii) shall be subject to the prior written consent of the Agent
(which consent shall not be unreasonably withheld).

         3.8 Survival. The agreements and obligations of the Borrowers in this
Article III shall survive the payment of all other Obligations.

                                   ARTICLE IV

                 (ii) A certificate of the Secretary or Assistant Secretary of
         each Borrower certifying the names and true signatures of the officers

<PAGE>   40



         4.2 Conditions to All Borrowings. The obligation of each Bank to make
any Loan to be made by it (including its initial Loan) is subject to the
satisfaction of the following conditions precedent on the relevant Borrowing
Date:

             (a) Notice of Borrowing. The Agent shall have received a Notice of
         Borrowing;

             (b)  Continuation of Representations and Warranties. The
         representations and warranties in Article V shall be true and correct
         on and as of such Borrowing Date with the same effect as if made on and
         as of such Borrowing Date (except to the extent such representations
         and warranties expressly refer to an earlier date, in which case they
         shall be true and correct as of such earlier date); and

             (c)  No Existing Default. No Default or Event of Default shall
         exist or shall result from such Borrowing. Each Notice of Borrowing
         submitted by a Borrower hereunder shall constitute a representation and
         warranty by such Borrower hereunder, as of the date of each such notice
         and as of each Borrowing Date, that the conditions in Section 4.2 are
         satisfied.

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

         Each Borrower represents and warrants to the Agent and each Bank that:

         5.1 Corporate Existence; Conduct of Business. Such Borrower and its
Subsidiaries (a) are corporations duly incorporated, validly existing and in
good standing under the laws of their respective jurisdictions of incorporation,
(b) are duly qualified and in good standing as foreign corporations in each
jurisdiction in which its ownership or lease of property or the conduct of its
business requires such qualification, except where failure to be so qualified
will not have a Material Adverse Effect, and (c) possess all licenses,
registrations and authorizations from and with any Governmental Authority,
self-regulatory organization or securities exchange necessary or material to the
conduct of its business as presently conducted. The Subsidiary Borrower is (a) a
broker- dealer duly registered under the Exchange Act, (b) a member in good
standing of the NASD, (c) not in arrears in regard to any assessment of the
SIPC, and (d) has received no notice from the SEC, MSRB, NASD or any other
Governmental Authority, self-regulatory organization or securities exchange of
any alleged rule violation or other circumstance which could reasonably be
expected to have a Material Adverse Effect.

         5.2 Authorization and Validity. Such Borrower has all requisite power
and authority (corporate and otherwise) to execute and deliver each of the Loan
Documents to which it is a party and to perform its obligations thereunder. The
execution and delivery by such Borrower of the Loan Documents to which it is a
party and the performance of its obligations thereunder have been duly

                                       33
<PAGE>   41


authorized by proper corporate proceedings and such Loan Documents constitute
legal, valid and binding obligations of such Borrower, enforceable against such
Borrower in accordance with their terms, except as enforceability may be limited
by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' right generally or by general principles of equity limiting the
availability of equitable remedies.

         5.3 Compliance with Laws and Contracts. Such Borrower and its
Subsidiaries have complied in all material respects with all applicable laws,
statutes, rules, regulations, orders and restrictions of any Governmental
Authority, self-regulatory organization or securities exchange having
jurisdiction over the conduct of their respective businesses or the ownership of
their respective properties (including, without limitation the Exchange Act, the
Advisers Act, the Investment Company Act and the applicable rules and
regulations of the SEC, NASD, NYSE, MSRB and CFTC), except where the failure to
so comply could not reasonably be expected to have a Material Adverse Effect.
Neither the execution and delivery by such Borrower of the Loan Documents, the
application of the proceeds of its Loans, the consummation of any transaction
contemplated by the Loan Documents, nor compliance with the provisions of the
Loan Documents will, or at the relevant time did, (a) violate any law, rule,
regulation (including Regulations T, U and X), order, writ, judgment,
injunction, decree or award binding on such Borrower or any Subsidiary thereof
or such Borrower's or any such Subsidiary's charter, articles or certificate of
incorporation or by-laws, (b) violate the provisions of or require the approval
or consent of any party to any indenture, instrument or agreement to which such
Borrower or any such Subsidiary is a party or is subject, or by which it, or its
property, is bound or conflict with or constitute a default thereunder, or
result in the creation or imposition of any Lien (other than Liens permitted by
Section 6.17) in, of or on the property of such Borrower or any such Subsidiary
pursuant to the terms of any such indenture, instrument or agreement, or (c)
require the consent or approval of any Person, except for any violation of, or
failure to obtain an approval or consent required under, any such indenture,
instrument or agreement that could not have a Material Adverse Effect.

         5.4 Governmental Consents. No order, consent, approval, qualification,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, or other action in respect of, any Governmental
Authority, self-regulatory organization or securities exchange is necessary or
required in connection with the execution, delivery, consummation performance
of, or the legality, validity, binding effect or enforceability of, any of the
Loan Documents, the application of the proceeds of the Loans, or the
consummation of any other transaction contemplated by the Loan Documents.
Neither such Borrower nor any Subsidiary thereof is in default under or in
violation of any foreign, federal, state or local law, rule, regulation, order,
writ, judgment, injunction, decree or award binding upon or applicable to such
Borrower or such Subsidiary, in each case the consequence of which default or
violation could reasonably be expected to have a Material Adverse Effect.

         5.5 Financial Statements. The Parent has heretofore furnished to each
of the Banks (a) the December 31, 1999 audited consolidated financial statements
of the Parent and its Subsidiaries, (b) the March 31, 2000 unaudited
consolidated financial statements of the Parent and its Subsidiaries, and (c)
the December 31, 1999 audited financial statements for the Subsidiary

                                       34
<PAGE>   42


Borrower (collectively, the "Financial Statements"). The Parent has also
heretofore furnished to each of the Banks the December 31, 1999, March 31, 2000
and June 30, 2000 quarterly Financial and Operational Combined Uniform Single
(FOCUS) Reports of the Subsidiary Borrower (the "FOCUS Reports"). Each of the
Financial Statements was prepared in accordance with GAAP and fairly presents
the consolidated financial condition, results of operations, changes in
stockholders' equity and cash flows of the Parent and its Subsidiaries (or of
the applicable Subsidiary, as the case may be) at such dates and for the
respective periods then ended (except, in the case of such unaudited statements,
for normal year-end audit adjustments). The FOCUS Reports are correct and
complete in all material respects and conform in all material respects to
Exchange Act requirements and applicable SEC rules and regulations.

         5.6 Material Adverse Change. No material adverse change in the
business, Property, condition (financial or otherwise), performance, or results
of operations of the Parent and its Subsidiaries taken as a whole has occurred
since December 31, 1999.

         5.7 Taxes. The Parent and its Subsidiaries have filed or caused to be
filed on a timely basis and in correct form all United States federal and
applicable state tax returns and other material tax returns which are required
to be filed and have paid all material taxes due pursuant to said returns or
pursuant to any assessment received by the Parent or any Subsidiary, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided in accordance with GAAP. As of the date hereof, the
United States income tax returns of the Parent on a consolidated basis have been
audited by the Internal Revenue Service through its Fiscal Year ending December
31, 1995 and, to the Parent's knowledge, there are no pending audits or
investigations regarding the Parent's or its Subsidiaries' federal, state or
local tax returns which could reasonably be expected to have a Material Adverse
Effect. No tax liens have been filed and no claims are being asserted with
respect to any such taxes which could reasonably be expected to have a Material
Adverse Effect. The charges, accruals and reserves on the books of the Parent
and its Subsidiaries in respect of any taxes or other governmental charges are
in accordance with GAAP.

         5.8 Litigation and Contingent Obligations. There is no litigation,
arbitration, proceeding, inquiry or investigation by any Governmental Authority,
self-regulatory organization or securities exchange pending or, to the knowledge
of any of such Borrower's officers, threatened against or affecting such
Borrower or any Subsidiary thereof or any of their respective Properties which
could reasonably be expected to have a Material Adverse Effect or to prevent,
enjoin or unduly delay the making of the Loans or the consummation of the
transactions contemplated by this Agreement. Neither such Borrower nor any
Subsidiary thereof has any material contingent obligations not provided for or
disclosed in the Financial Statements.

         5.9 Subsidiaries. Schedule 5.9 hereto contains an accurate list of all
of the Parent's existing Subsidiaries as of the date of this Agreement, setting
forth their respective jurisdictions of incorporation and the percentage of
their capital stock owned by the Parent or other Subsidiaries. Except as set
forth on Schedule 5.9 and except for Seed Money, as of the date hereof, the
Parent does not own or hold, directly or indirectly, any capital stock or equity
security of, or any equity partnership interest in, any Person other than such
Subsidiaries.

                                       35
<PAGE>   43



         5.10 ERISA. Except as disclosed on Schedule 5.10, neither the Parent
nor any other member of the Controlled Group maintains any Single Employer
Plans, and no Single Employer Plan has any Unfunded Liability. Neither the
Parent nor any other member of the Controlled Group maintains, or is obligated
to contribute to, any Multiemployer Plan or has incurred, or is reasonably
expected to incur, any withdrawal liability to any Multiemployer Plan. Each Plan
complies in all material respects with all applicable requirements of law and
regulations. Neither the Parent nor any member of the Controlled Group has, with
respect to any Plan, failed to make any contribution or pay any amount required
under Section 412 of the Code or Section 302 of ERISA or the terms of such Plan
which could reasonably be expected to be in excess of $5,000,000. There are no
pending or, to the knowledge of the Parent, threatened claims, actions,
investigations or lawsuits against any Plan, any fiduciary thereof, or the
Parent or any member of the Controlled Group with respect to a Plan which could
reasonably be expected to have a Material Adverse Effect. Neither the Parent nor
any member of the Controlled Group has engaged in any prohibited transaction (as
defined in Section 4975 of the Code or Section 406 of ERISA) in connection with
any Plan which would subject such Person to any material liability. Within the
last five years neither the Parent nor any member of the Controlled Group has
engaged in a transaction which resulted in a Single Employer Plan with an
Unfunded Liability being transferred out of the Controlled Group. No Termination
Event has occurred or is reasonably expected to occur with respect to any Plan
which is subject to Title IV of ERISA.

         5.11 Defaults. No Event of Default or Default has occurred and is
continuing.

         5.12 Federal Reserve Regulations. Neither such Borrower nor any
Subsidiary thereof is engaged, directly or indirectly, principally, or as one of
its important activities, in the business of extending or arranging for the
extension of, credit for the purpose of purchasing or carrying Margin Stock. No
part of the proceeds of any Loan will be used in a manner which would violate,
or result in any violation of, Regulation T, Regulation U or Regulation X.
Neither the making of a Loan hereunder or the use of the proceeds thereof will
violate or be inconsistent with the provisions of, Regulation T, Regulation U or
Regulation X. Following the application of the proceeds of the Loans, less than
25% of the value (as determined by any reasonable method) of the assets of the
Borrowers and their Subsidiaries which are subject to any limitation on sale,
pledge, or other restriction hereunder taken as a whole have been, and will
continue to be, represented Margin Stock.

         5.13 Investment Company; Public Utility Holding Company. Neither such
Borrower nor any Subsidiary thereof is, or after giving effect to any Loan will
be, an "investment company" or a company "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended. Neither
such Borrower nor any Subsidiary thereof is subject to regulation under the
Public Utility Holding Company Act of 1935, as amended.

         5.14 Certain Fees. No broker's or finder's fee or commission was, is or
will be payable by such Borrower or any Subsidiary thereof with respect to any
of the transactions contemplated by this Agreement. Borrowers hereby jointly and
severally agree to indemnify the Agent and the Banks against and agree that they
will hold each of them harmless from any claim, demand or liability for any
broker's finder's fees or commissions alleged to have been incurred by the
Borrowers in

                                       36
<PAGE>   44


connection with any of the transactions contemplated by this Agreement and any
expenses (including, without limitation, attorneys' fees and time charges of
attorneys for the Agent or any Bank, which attorneys may be employees of the
Agent or any Lender) arising in connection with any such claim, demand or
liability. No other similar fee or commissions will be payable by such Borrower
or any Subsidiary thereof for any other services rendered to such Borrower or
such Subsidiary thereof ancillary to any of the transactions contemplated by
this Agreement.

         5.15 Ownership of Properties. Such Borrower and its Subsidiaries have a
subsisting leasehold interest in, or good and marketable title, free of all
Liens, other than those permitted by Section 6.17, to all of the properties and
assets reflected in the Financial Statements as being owned by it, except for
assets sold, transferred or otherwise disposed of in the ordinary course of
business since the date thereof and such defects of title and Liens as could
not, individually or in the aggregate, have a Material Adverse Effect. To the
knowledge of such Borrower, there are no actual, threatened or alleged defaults
with respect to any leases of real property under which such Borrower or any
Subsidiary thereof is lessee or lessor which could reasonably be expected to
have a Material Adverse Effect.

         5.16 Material Agreements. Neither such Borrower nor any Subsidiary
thereof is a party to any agreement or instrument or subject to any charter or
other corporate restriction which could reasonably be expected to have a
Material Adverse Effect or which restricts or imposes conditions upon the
ability of any Subsidiary thereof to (a) pay dividends or make other
distributions on its capital stock, (b) make loans or advances to such Borrower,
(c) repay loans or advances from such Borrower, or (d) grant Liens to the Agent
to secure the Obligations. Neither such Borrower nor any Subsidiary thereof is
in default in the performance, observance or fulfilment of any of the
obligations, covenants or conditions contained in any agreement to which it is a
party, which default could reasonably be expected to have a Material Adverse
Effect.

         5.17 Insurance. Such Borrower and its Subsidiaries maintain with
financially sound and reputable insurance companies insurance on their Property
in such amounts and covering such risk as is consistent with sound business
practice.

         5.18 Disclosure. None of the (a) information, exhibits or reports
furnished or to be furnished by such Borrower or any Subsidiary thereof to the
Agent or to any Bank in connection with the negotiation of the Loan Documents,
taken as a whole, or (b) representations or warranties of such Borrower or any
Subsidiary thereof contained in this Agreement, the other Loan Documents or any
other document, certificate or written statement furnished to the Agent or the
Banks by or on behalf such Borrower or any Subsidiary thereof pursuant to this
Agreement contained, contains or will contain any untrue statement of a material
fact or omitted, omits or will omit to state a material fact necessary in order
to make the statements contained herein or therein not misleading in light of
the circumstances in which they were made. There is no fact known to such
Borrower (other than matters of a general economic nature) that has had or could
reasonably be expected to have a Material Adverse Effect and that has not been
disclosed herein or in such other documents, certificates and statements
furnished to the Banks for use in connection with the transactions contemplated
by this Agreement.

                                   COVENANTS

         During the term of this Agreement, unless the Majority Banks shall
otherwise consent in writing:

     6.1 Financial Reporting. The Parent will maintain, for itself and
each Subsidiary, a system of accounting established and administered in
accordance with GAAP, consistently applied, and will furnish to the Agent, with
sufficient copies for the Banks:

          (a) As soon as practicable and in any event within 90 days after the
     close of each of its fiscal years, an unqualified audit report certified by
     KPMG or other independent certified public accountants, acceptable to the
     Banks, prepared in accordance with GAAP on a consolidated and consolidating
     basis (consolidating statements need not be certified by such accountants)
     for itself and its Subsidiaries and for the Subsidiary Borrower (other than
     consolidating financial statements), and to the extent available, for
     Nuveen Advisory, Nuveen Institutional, Nuveen Asset Management and
     Rittenhouse, including balance sheets as of the end of such period and
     related statements of income, and changes in stockholders' equity (to the
     extent available for entities other than the Parent) and cash flows
     (provided that so long as the common stock of the Parent is listed for
     trading on the NYSE, the foregoing requirement as to the Parent's
     consolidated financial statements may be satisfied by the delivery of the
     Parent's Annual Report to Stockholders and its Annual Report on Form 10-K
     filed with the SEC containing such information) and accompanied by (i) any
     management letter prepared by said accountants and (ii) a certificate of
     said accountants that, in the course of the examination necessary for their
     certification of the foregoing, they have obtained no knowledge of any
     Event of Default or Default, or if, in the opinion of such accountants, any
     Event of Default or Default shall exist, stating the nature and status
     thereof.

          (b) As soon as practicable and in any event within 45 days after the
     close of the first three fiscal quarters of each of its fiscal years, for
     itself and its Subsidiaries, and for each of the Subsidiary Borrower,

     Rittenhouse consolidated unaudited balance sheets as at the close of each
     such period and consolidated statements of income, changes in stockholders'
     equity and cash flows for the period from the beginning of such fiscal year

                                  ARTICLE VIII

                                   GUARANTEE

     8.1 Guarantee. The Parent hereby absolutely, unconditionally and
irrevocably (all of the following guaranteed and indemnified obligations being
collectively called the "Guaranteed Indebtedness"):

          (a) guarantees the full and punctual payment when due, whether at
     stated maturity, by required prepayment, declaration, acceleration, demand
     or otherwise, of all Obligations of the Subsidiary Borrower, now or
     hereafter existing whether for principal, interest, fees, expenses or
     otherwise, whether direct or indirect, absolute or contingent or now or
     hereafter existing or due or to become due (including in all cases all such
     amounts which would become due but for the operation of the automatic stay
     under Section 362(a) of the United States Bankruptcy Code, 11 U.S.C.
     Section 362(a), and the operation of Sections 502(b) and 506(b) of the
     United States Bankruptcy Code, 11 U.S.C. Section 502(b) and Section
     506(b)), and

          (b) indemnifies and holds harmless each Bank and the Agent for any and
     all costs and expenses (including reasonable attorneys' fees and expenses)
     incurred by such Bank in enforcing any rights under this Article VIII.

     8.2 Expenses. The Parent, irrevocably and unconditionally agrees to pay any
and all expenses, including reasonable attorneys' fees and disbursements
(including the allocated cost of internal counsel), incurred by any of the Banks
or the Agent in enforcing its rights under or in connection with this Article
VIII.

     8.3 Waivers. The Parent agrees that the Guaranteed Indebtedness may be
extended or renewed, in whole or in part, without notice to or further assent
from it and without impairing its obligations under this Article VIII. The
Parent hereby waives (a) presentation to, demand of payment from, and protest
and notice of protest concerning the Guaranteed Indebtedness, (b) protest for
nonpayment of principal of or interest on the Guaranteed Indebtedness and (c)
all other notices to which it might otherwise be entitled as guarantor of the
Guaranteed Indebtedness.

     8.4 No Impairment. The obligations of the Parent under this Article VIII
shall not be impaired by reason of any claim or waiver, release, surrender or
compromise with respect to the Subsidiary Borrower, and shall not be subject to
any defense or set-off by reason of the unenforceability, in whole or in part,
of the Guaranteed Indebtedness or any provision of this Agreement with respect
to the Subsidiary Borrower. The obligations of the Parent hereunder with respect
to its guaranty of the obligations of the Subsidiary Borrower hereunder shall
not be impaired by (a) any lack of validity or enforceability of this Agreement
or any other Loan Document with respect to the Subsidiary Borrower, (b) the
failure of any of the Banks or the Agent to assert any claim or demand or to
enforce any right or remedy against the Subsidiary Borrower or any other Person
hereunder or under the other Loan Documents or with respect to this Agreement or
the other


                                       48

<PAGE>   56


Loan Documents, (c) any extension or renewal, in whole or in part, of this
Agreement or any other Loan Documents, (d) any rescission, waiver, release,
compromise, amendment or modification of, or any consent to departure from, any
of the terms or provisions of this Agreement or the other Loan Documents or any
agreement, (e) any failure by any Person in the performance of any obligation
with respect to this Agreement or any other Loan Documents, (f) any act by the
Agent or any Bank to obtain or retain a Lien upon or a security interest in any
property to secure any Guaranteed Indebtedness, or to release any security for
any of the Guaranteed Indebtedness, (g) any exchange, release or nonperfection
of any Lien, (h) any bankruptcy of the Subsidiary Borrower or any other Person,
or (i) any other act or omission which may or might in any manner vary the risk
of the Subsidiary Borrower, or which would otherwise operate as a discharge of
or other defense available to the Subsidiary Borrower, as a matter of law.

     8.5 Waiver of Resort. The Parent agrees that this Article VIII constitutes
a guaranty of payment and not merely of collection and waives any right to
require that any resort be had by the Agent or any of the Banks to any security
held by it for the payment of the Guaranteed Indebtedness or to any balance or
any deposit account or credit on the books of the Agent or any Bank in favor of
the Subsidiary Borrower.

     8.6 Reinstatement. The Parent agrees that this Article VIII shall continue
to be effective or be reinstated, as the case may be, if at any time any part of
any payment of principal of, or interest on, the Guaranteed Indebtedness is
stayed, rescinded or must otherwise be returned by any Bank or the Agent upon
the bankruptcy or reorganization of the Subsidiary Borrower or any other Person.

     8.7 Payment. Upon the failure of the Subsidiary Borrower to pay any of the
Guaranteed Indebtedness when and as the same shall become due, whether at
maturity, by acceleration or otherwise, the Parent hereby promises to, and will,
immediately on demand by any Bank or the Agent, pay or cause to be paid to the
Banks or the Agent, as the case may be, an amount equal to the full amount of
the Guaranteed Indebtedness then due. All such payments shall be in the currency
in which the Guaranteed Indebtedness is denominated.

     8.8 Subrogation, Waivers, etc. The Parent hereby agrees that, until such
time as all of the Guaranteed Obligations shall have been finally paid in full
in cash and performed in full, all Commitments shall have terminated, and this
guaranty shall have been discontinued, no payment made by or on account of the
Subsidiary Borrower pursuant to this Article VIII shall entitle the Parent, by
subrogation or otherwise, to any payment by the Subsidiary Borrower or from or
out of any property of the Subsidiary Borrower, and the Parent shall not
exercise any right or remedy against the Subsidiary Borrower or any property of
the Subsidiary Borrower by reason of any performance by the Parent of its
obligations under this Article VIII, including any claim or other rights which
it may now or hereafter acquire against the Subsidiary Borrower that arise from
the existence, payment, performance or enforcement of the guaranty under this
Article VIII, including any right of subrogation, reimbursement, exoneration,
contribution, indemnification, any right to participate in any claim or remedy
of the Banks or the Agent, as the case may be, against the Subsidiary Borrower
or any collateral now or hereafter pledged to the Banks, the Agent or any other
Person acting on behalf of the Banks by the Subsidiary Borrower, whether or not
such claim, remedy


                                       49

<PAGE>   57


or right arises in equity, at law or under contract, directly or indirectly, is
for cash or other property or arises by set-off or in any other manner (as
payment or security on account of such claim or other rights). If any amount
shall be paid to the Parent in violation of the preceding sentence and the
Obligations shall not then have been paid in full, all Commitments shall not
have terminated, such amount shall be deemed to have been paid to the Parent for
the benefit of, and held in trust for the benefit of, the Banks or the Agent, as
applicable, and shall forthwith be paid to the Banks or the Agent, as
applicable. The Parent acknowledges that it has received and will receive direct
and indirect benefits from the financing arrangements contemplated by this
Agreement and the other Loan Documents and that the forbearance set forth in
this Section 8.8 is knowingly granted in contemplation of such benefits.

     8.9 Delay, etc. No delay on the part of any of the Banks or the Agent in
exercising any rights under this Article VIII or failure to exercise the same
shall operate as a waiver of such rights. No notice to or demand on the Parent
shall be deemed to be a waiver of any obligation of the Subsidiary Borrower or
the right of the Banks or the Agent to take further action without notice or
demand as provided herein.

                                   ARTICLE IX

                                   THE AGENT

     9.1 Appointment and Authorization. Each Bank hereby irrevocably (subject to
Section 9.9) appoints, designates and authorizes the Agent to take such action
on its behalf under the provisions of this Agreement and each other Loan
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 Loan 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 Loan 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 Loan Document or otherwise exist against the
Agent.

     9.2 Delegation of Duties. The Agent may execute any of its duties under
this Agreement or any other Loan 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.

     9.3 Liability of Agent. None of the Agent-Related Persons shall (i) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan 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 Subsidiary
or Affiliate


                                       50
<PAGE>   58


of any Borrower, or any officer thereof, contained in this Agreement or in any
other Loan 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 Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of either Borrower or any other party to any Loan
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 the agreements contained in, or
conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of the Borrower or any of the Borrower's
Subsidiaries or Affiliates.

     9.4 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 the
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 Loan 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 Loan 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.

     9.5 Notice of Default. The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of 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 Borrower referring to this Agreement, describing
such Default or Event of 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 or Event of Default as
may be requested by the Majority Banks in accordance with Article VIII;
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 or Event of
Default as it shall deem advisable or in the best interest of the Banks.

     9.6 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 Parent and
its Subsidiaries, 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


                                       51
<PAGE>   59



and investigation into the business, prospects, operations, property, financial
and other condition and creditworthiness of the Parent and its Subsidiaries, 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 Loan 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, 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.

     9.7 Indemnification. 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 liabilities indemnified by the Borrowers pursuant to Section 10.5;
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 Loan
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.

     9.8 Agent in Individual Capacity. Bank of America 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 Parent and its
Subsidiaries and Affiliates as though Bank of America were not the Agent
hereunder and without notice to or consent of the Banks. The Banks acknowledge
that, pursuant to such activities, Bank of America 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 or
such Subsidiary) and acknowledge that the Agent shall be under no obligation to
provide such information to them. With respect to its Loans, Bank of America
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 Bank of America in its individual capacity.

     9.9 Successor Agent. The Agent may, and at the request of the Majority
Banks shall, resign as Agent upon 30 days' notice to the Banks. 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 approved by
the Parent. 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 Parent, 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 IX and
Sections 10.4 and 10.5 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.

     9.10. Withholding Tax. (a) If any Bank is a "foreign corporation,
partnership or trust" within the meaning of the Code and such Bank claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the Code, such Bank agrees with and in favor of the Agent, to deliver to
the Agent:

               (i) if such Bank claims an exemption from, or a reduction of,
          withholding tax under a United States tax treaty, two properly
          completed copies of IRS Form W-8 BEN on or before the payment of any
          interest in the first calendar year and before the payment of any
          interest in each third succeeding calendar year during which interest
          may be paid under this Agreement;

               (ii) if such Bank claims that interest paid under this Agreement
          is exempt from United States withholding tax because it is effectively
          connected with a United States trade or business of such Bank, two
          properly completed and executed copies of IRS Form W-8ECI before the
          payment of any interest is due in the first taxable year of such Bank
          and in each succeeding taxable year of such Bank during which interest
          may be paid under this Agreement,

               (iii) if such Bank is a foreign partnership or other intermediary
          and its partners claim an exemption from, or a reduction of,
          withholding tax under a United States tax treaty or if its partners
          claim that interest paid under this Agreement is exempt from United
          States withholding tax because it is effectively connected with the
          conduct with a United States trade or business, two properly completed
          and executed copies of IRS Form W-8MY on or before the payment of any
          interest in the first calendar year and before the payment of any
          interest in each third succeeding calendar year during which interest
          may be paid under this Agreement; and


                                       53
<PAGE>   61


               (iv) such other 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.

               Such Bank agrees to promptly notify the Agent of any change in
          circumstances which would modify or render invalid any claimed
          exemption or reduction.

          (b) If any Bank claims exemption from, or reduction of, withholding
     tax under a United States tax treaty by providing IRS Form W-8BEN and such
     Bank sells, assigns, grants a participation in, or otherwise transfers all
     or part of the Obligations of the Borrowers to such Bank, such Bank agrees
     to notify the Agent of the percentage amount in which it is no longer the
     beneficial owner of Obligations of the Borrowers to such Bank. To the
     extent of such percentage amount, the Agent will treat such Bank's IRS Form
     W-8BEN as no longer valid.

          (c) If any Bank claiming exemption from United States withholding tax
     by filing IRS Form W-8ECI with the Agent sells, assigns, grants a
     participation in, or otherwise transfers all or part of the Obligations of
     the Borrowers 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 any Bank is a foreign partnership or other intermediary and its
     partners claim exemption from, or reduction of, withholding tax under a
     United States tax treaty by providing IRS Form W-8BEN or its partners claim
     exemption from United States withholding tax by filing IRS Form W-8ECI, and
     any of its partners sell, assign, grant a participation in, or otherwise
     transfer all or part of the Obligations of any Borrower to such Bank, such
     Bank agrees to notify the Agent of the percentage amount in which the
     partners is no longer the beneficial owner of Obligations of any Borrower
     to such Bank. To the extent of such percentage amount, the Agent will treat
     such partner's IRS Form W-8BEN or W-8ECI as no longer valid.

          (e) If any Bank is entitled to a reduction in the applicable
     withholding tax, the Agent may withhold from any interest payment to such
     Bank an amount equivalent to the applicable withholding tax after taking
     into account such reduction. If the forms or other documentation required
     by subsection (a) of this Section are not delivered to the Agent, then the
     Agent may withhold from any interest payment to such Bank not providing
     such forms or other documentation an amount equivalent to the applicable
     withholding tax.

          (f) If the IRS or any other Governmental Authority of the United
     States or other jurisdiction asserts a claim that the Agent 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 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 fully for all


                                       54
<PAGE>   62


     amounts paid, directly or indirectly, by the Agent as tax or
     otherwise, including penalties and interest, and including any taxes
     imposed by any jurisdiction on the amounts payable to the Agent 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.

     9.11 Documentation Agent; Syndication Agent. None of the Banks identified
on the facing page or signature pages of this Agreement as a "documentation
agent" or "syndication agent" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement other than those
applicable to all Banks as such. Without limiting the foregoing, none of the
Banks so identified as a "documentation agent" or "syndication agent" shall have
or be deemed to have any fiduciary relationship with any Bank. Each Bank
acknowledges that it has not relied, and will not rely, on any of the Banks so
identified in deciding to enter into this Agreement or in taking or not taking
action hereunder.

          (c) Any agreement of the Agent and the Banks herein to receive certain

     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 the Borrowers 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 the Borrowers 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.

     10.3 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


                                       56
<PAGE>   64



hereunder preclude any other or further exercise thereof or the exercise of
any other right, remedy, power or privilege.

     10.4 Costs and Expenses. The Borrowers shall jointly and severally:

          (a) whether or not the transactions contemplated hereby are
     consummated, pay or reimburse Bank of America (including in its capacity as
     Agent) within five Business Days after demand for all costs and expenses
     incurred by Bank of America (including in its capacity as Agent) in
     connection with the development, preparation, delivery, administration and
     execution of, and any amendment, supplement, waiver or modification to (in
     each case, whether or not consummated), this Agreement, any Loan 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 Bank of America (including
     in its capacity as Agent) with respect thereto; and

          (b) 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 Loan 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).

     10.5 Indemnity. Whether or not the transactions contemplated hereby
are consummated, the Borrowers shall jointly and severally indemnify and hold
harmless the Agent, the Arranger, each Bank and each of their Affiliates and
their directors, officers, employees, advisors and agents (each, an "Indemnified
Party") from and against (and will reimburse each Indemnified Party as the same
are incurred) any and all losses, claims, damages, liabilities, and expenses
(including, without limitation, the reasonable fees and expenses of counsel and
the allocated cost of internal counsel) that may be incurred by or asserted or
awarded against any Indemnified Party, in each case arising out of or in
connection with or by reason of (including, without limitation, in connection
with any investigation, litigation or proceeding or preparation of a defense in
connection therewith) any matters contemplated by this Agreement, any related
transaction or any use made or proposed to be made with the proceeds thereof
unless and only to the extent that, as to any Indemnified Party, it shall be
determined in a final nonappealable judgment by a court of competent
jurisdiction that such losses, claims, damages, liabilities or expenses resulted
primarily from the gross negligence or willful misconduct of such Indemnified
Party. Notwithstanding the foregoing, the Borrowers shall have no obligation to
any Indemnified Party in respect of losses, claims, damages, liabilities or
expenses arising from (a) disputes between Banks, the Agent and/or the Arranger
or (b) disputes between any Borrower and an Indemnified Party, with respect to
which such Borrower is the prevailing party unless such losses, claims, damages,
liabilities or expenses under this clause (b) arise from the negligence (but not
gross negligence or willful misconduct) of such Indemnified Party.


                                       57
<PAGE>   65



     10.6 Collateral. The Borrowers, or either Borrower, may at their
option provide collateral to secure the Obligations in whole or in part in form
and with collateral reasonably satisfactory to the Majority Banks. The Banks
acknowledge and agree that the Collateral listed on Schedule 10.6 is
satisfactory. Any collateral agent shall be deemed included in the definition of
"Agent" and have the benefit of Article IX.

     10.7 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.

     10.8 Successors and Assigns. The provisions of this Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Borrowers may not assign or
transfer any of their rights or obligations under this Agreement without the
prior written consent of the Agent and each Bank.

     10.9 Assignments, Participations, etc. (a) Any Bank may, with the
written consent of the Borrowers at all times other than during the existence of
an Event of Default and the Agent, which consent of the Borrowers shall not be
unreasonably withheld, at any time assign and delegate to one or more Eligible
Assignees (provided that no written consent of the Borrowers or the Agent shall
be required in connection with any assignment and delegation by a Bank to an
Eligible Assignee that is an Affiliate of such Bank) (each an "Assignee") all,
or any ratable part of all, of the Loans, the Commitments and the other rights
and obligations of such Bank hereunder, in a minimum amount of $5,000,000;
provided, however, that the Borrowers and the Agent may continue to deal solely
and directly with such Bank in connection with the interest so assigned to an
Assignee until (i) written notice of such assignment, together with payment
instructions, addresses and related information with respect to the Assignee,
shall have been given to the Borrowers and the Agent by such Bank and the
Assignee; (ii) such Bank and its Assignee shall have delivered to the Borrower
and the Agent an Assignment and Acceptance in the form of Exhibit E ("Assignment
and Acceptance") together with any Note or Notes subject to such assignment and
(iii) the assignor Bank or Assignee has paid to the Agent a processing fee in
the amount of $3,500.

          (b) From and after the date that the Agent notifies the assignor Bank
     that it has received (and provided its and the Borrowers', if applicable,
     consent with respect to) an executed Assignment and Acceptance and payment
     of the above-referenced processing fee, (i) the Assignee thereunder shall
     be a party hereto and, to the extent that rights and obligations hereunder
     have been assigned to it pursuant to such Assignment and Acceptance, shall
     have the rights and obligations of a Bank under the Loan Documents, and
     (ii) the


                                       58
<PAGE>   66



     assignor Bank shall, to the extent that rights and obligations hereunder
     and under the other Loan Documents have been assigned by it pursuant to
     such Assignment and Acceptance, relinquish its rights and be released from
     its obligations under the Loan Documents.

          (c) Within five Business Days after its receipt of notice by the Agent
     that it has received an executed Assignment and Acceptance and payment of
     the processing fee, (and provided that it and the Borrowers, if applicable,
     consent to such assignment in accordance with Section 10.9(a)), the
     Borrowers shall execute and deliver to the Agent, new Notes evidencing such
     Assignee's assigned Loans and Commitment and, if the assignor Bank has
     retained a portion of its Loans and its Commitment, replacement Notes in
     the principal amount of the Loans retained by the assignor Bank (such Notes
     to be in exchange for, but not in payment of, the Notes held by such Bank).
     Immediately upon each Assignee's making its processing fee payment under
     the Assignment and Acceptance, this Agreement shall be deemed to be amended
     to the extent, but only to the extent, necessary to reflect the addition of
     the Assignee and the resulting adjustment of the Commitments arising
     therefrom. The Commitment allocated to each Assignee shall reduce such
     Commitments of the assigning Bank pro tanto.

          (d) Any Bank, with notice to the Borrowers, may at any time sell to
     one or more commercial banks or other Persons not Affiliates of the
     Borrower (a "Participant") participating interests in any Loans, the
     Commitment of that Bank and the other interests of that Bank (the
     "originating Bank") hereunder and under the other Loan Documents; provided,
     however, that (i) the originating Bank's obligations under this Agreement
     shall remain unchanged, (ii) the originating Bank shall remain solely
     responsible for the performance of such obligations, (iii) the Borrowers
     and the Agent shall continue to deal solely and directly with the
     originating Bank in connection with the originating Bank's rights and
     obligations under this Agreement and the other Loan Documents, and (iv) no
     Bank shall transfer or grant any participating interest under which the
     Participant has rights to approve any amendment to, or any consent or
     waiver with respect to, this Agreement or any other Loan Document, except
     to the extent such amendment, consent or waiver would require unanimous
     consent of the Banks as described in the first proviso to Section 10.1. In
     the case of any such participation, the Participant shall be entitled to
     the benefit of Sections 3.1, 3.3 and 10.5 as though it were also a Bank
     hereunder, and not have any rights under this Agreement, or any of the
     other Loan Documents, and all amounts payable by the Borrowers hereunder
     shall be determined as if such Bank had not sold such participation; except
     that, if amounts outstanding under this Agreement are due and unpaid, or
     shall have been declared or shall have become due and payable upon the
     occurrence of an Event of Default, each Participant shall be deemed to have
     the right of set-off in respect of its participating interest in amounts
     owing under this Agreement to the same extent as if the amount of its
     participating interest were owing directly to it as a Bank under this
     Agreement.

          (e) Notwithstanding any other provision in this Agreement, any Bank
     may at any time create a security interest in, or pledge, all or any
     portion of its rights under and interest in this Agreement and the Note
     held by it in favor of any Federal Reserve Bank in


                                       59
<PAGE>   67



     accordance with Regulation A of the FRB or U.S. Treasury Regulation 31 CFR
     Section 203.14, and such Federal Reserve Bank may enforce such pledge or
     security interest in any manner permitted under applicable law.

     10.10 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 information identified as "confidential" or
"secret" by the Borrowers and provided to it by the Borrowers or any Subsidiary,
or by the Agent on such Borrower's or Subsidiary's behalf, under this Agreement
or any other Loan 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 Loan Documents or in connection with other business now
or hereafter existing or contemplated with any Borrower or any Subsidiary;
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 any
Borrower, provided that such source is not bound by a confidentiality agreement
with any 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 court 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 Loan Document; (F) 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 required of 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 any Borrower or any
Subsidiary is party or is deemed party with such Bank or such Affiliate; and (I)
to its Affiliates which shall be bound by the terms of this Section 10.10.

     10.11 Set-off. In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Borrowers, any such notice being waived by the Borrowers 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 the Borrowers against any and all Obligations 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 Loan Document and although
such Obligations may be contingent or unmatured. Each Bank agrees promptly to
notify the Borrowers 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.

     10.12 Automatic Debits of Fees.  With respect to any  fee, or any other
cost or expense (including Attorney Costs) due and payable to the Agent,
Bank of America or the Arranger under


                                       60
<PAGE>   68



the Loan Documents, the Borrowers hereby irrevocably authorize Bank of America
to debit any deposit account of the applicable Borrower with Bank of America in
an amount such that the aggregate amount debited from all such deposit accounts
does not exceed such fee or other cost or expense. If there are insufficient
funds in such deposit accounts to cover the amount of the fee or other cost or
expense then due, such debits will be reversed (in whole or in part, in Bank of
America's sole discretion) and such amount not debited shall be deemed to be
unpaid. No such debit under this Section shall be deemed a set-off.

     10.13 Notification of Addresses, Lending Offices, Etc. Each Bank shall
notify the Agent in writing of any changes in the address to which notices to
the Bank should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

     10.14 Counterparts. This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

     10.15 Severability. The illegality or unenforceability of any provision of
this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

     10.16 No Third Parties Benefitted. This Agreement is made and entered into
for the sole protection and legal benefit of the Borrowers, the Banks, the Agent
and the Agent-Related Persons, and their permitted successors and assigns, and
no other Person shall be a direct or indirect legal beneficiary of, or have any
direct or indirect cause of action or claim in connection with, this Agreement
or any of the other Loan Documents.

     10.17 Governing Law and Jurisdiction. (a) THIS AGREEMENT AND THE NOTES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF
ILLINOIS; PROVIDED THAT THE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING
UNDER FEDERAL LAW.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
     ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF
     ILLINOIS OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF ILLINOIS, AND
     BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE BORROWERS, THE
     AGENT AND THE BANKS CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO
     THE NON- EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH OF THE BORROWERS, THE
     AGENT AND THE BANKS IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY
     OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
     CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY
     ACTION OR PROCEEDING IN SUCH


                                       61
<PAGE>   69



     JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED
     HERETO. THE BORROWERS, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE
     OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER
     MEANS PERMITTED BY ILLINOIS LAW.

     10.18 Waiver of Jury Trial. THE BORROWERS, THE BANKS AND THE AGENT EACH
WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN
DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION,
PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST
ANY OTHER PARTY OR ANY AGENT-RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER
WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE. THE BORROWERS, THE
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
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED
BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

     10.19 Entire Agreement. This Agreement, together with the other Loan
Documents, embodies the entire agreement and understanding among the Borrowers,
the Banks and the Agent, and supersedes all prior or contemporaneous agreements
and understandings of such Persons, verbal or written, relating to the subject
matter hereof and thereof.

     Re:  Three Year Revolving Credit Agreement (the "3 Year Credit Agreement")
          and 364 Day Revolving Credit Agreement (the "364 Day Credit
          Agreement"), both dated as of August 10, 2000 (collectively, the
          "Credit Agreements") and entered into among The John Nuveen Company, a
          Delaware corporation, ("Nuveen"), Nuveen Investments, a Delaware
          corporation ("Nuveen Investments"; together with Nuveen, the
          "Borrowers" or "Borrower"), the banks party thereto (the "Lenders"),
          Citicorp USA, Inc., as Syndication Agent, The Chase Manhattan Bank, as
          Documentation Agent and Bank of America, N.A., as Administrative
          Agent.

Ladies and Gentlemen:

         We have acted as special counsel to the Borrowers in connection with
the Credit Agreements. This opinion is delivered to you responsive to Section
4.1(d) of the Credit Agreements. Capitalized terms used herein and not otherwise
defined have the meanings ascribed in the Credit Agreements. The Credit
Agreements and the Notes of the Borrowers delivered in connection therewith are
referred to herein as the "Loan Documents".

         We have examined executed counterparts of the Credit Agreements and
originals of the Notes, if any. We also have examined originals, or copies
certified or otherwise identified to our satisfaction, of such agreements,
corporate records, instruments, certificates of public officials and corporate
officers and such matters of law as we deemed necessary for purposes of this
opinion. We have relied, without independent investigation, upon statements of
officers of the Borrowers and the representations and warranties of the
Borrowers set forth in the Credit Agreements as to the nature of each Borrower's
business, its intended use of the proceeds of Borrowings under the Credit


                              Exhibit D-1, Page 1


<PAGE>   89


Agreements, the existence of any order, writ, judgment, decree, determination or
award that is binding upon the Borrowers, and as to pending or threatened
actions, suits, proceedings, governmental investigations or arbitrations. For
purposes of our opinions in paragraph 1, we have relied exclusively upon
certificates issued by a governmental authority in each relevant jurisdiction
and such opinions are not intended to provide any conclusion or assurance beyond
that conveyed by those certificates.

     We have assumed the genuineness of all signatures, the legal capacity of
all individuals who have executed the Loan Documents and all other documents we
have reviewed, the authenticity of all documents submitted to us as originals
and the conformity to original documents of all documents submitted to us as
copies. We also have assumed that the Credit Agreements have been duly
authorized, executed and delivered by each of the parties thereto (other than
the Borrowers) and are enforceable against such parties in accordance with their
terms. The term "actual knowledge" whenever it is used in this letter with
respect to our firm means conscious awareness on the date of this letter of
Dewey B. Crawford, Edward J. Tabaczyk and Charles J. Kolin, who are all of the
Gardner, Carton & Douglas attorneys who have given substantial attention to this
matter on behalf of the Borrowers.

     Based upon the foregoing, and subject to the qualifications stated herein,
we are of the opinion that:

     1. Each Borrower is a corporation validly existing and in good standing
under the laws of the State of Delaware. Nuveen is duly qualified, in good
standing and authorized to conduct business as a foreign corporation in the
State of Illinois. Nuveen Investments is duly qualified, in good standing and
authorized to conduct business as a foreign corporation under the name John
Nuveen and Co. Incorporated in Illinois and is in the process of changing its
name to Nuveen Investments in accordance with applicable Illinois law.

     2. Each Borrower has all requisite corporate power and authority to
execute, deliver and perform its obligations under each of the Loan Documents,
to own its assets and to carry on its business as presently conducted.

     3. The execution, delivery and performance by each Borrower of the Loan
Documents to which it is a party do not (a) violate any law, rule or regulation
(including Regulations T, U and X of the Board of Governors of the Federal
Reserve System) which, in our experience, is normally applicable both to general
business corporations (giving due regard to the regulated business activities of
Nuveen Investments and to the unregulated nature of the business activities of
Nuveen) and to transactions of the type contemplated by the Loan Documents, or,
to our actual knowledge, any order, writ, judgment, decree, determination or
award that is presently in effect and binding on such Borrower or (b) conflict
with or result in a breach of, or constitute a default under, the certificate of
incorporation or by-laws of such Borrower.

     4. Each of the Loan Documents to which it is a party has been duly
authorized, executed and delivered by such Borrower and constitutes the valid
and binding obligation of such Borrower,


                              Exhibit D-1, Page 2


<PAGE>   90


enforceable against such Borrower in accordance with its terms, except to the
extent that enforcement thereof may be limited by applicable bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or similar laws of
general application relating to or affecting the enforcement of the rights of
creditors or by equitable principles, regardless of whether enforcement is
sought in a proceeding in equity or at law.

     5. No authorization, consent, approval, license, qualification or formal
exemption from, or filing, declaration or registration with, any Federal or
Illinois State governmental agency or authority is required in connection with
the execution or delivery by the Borrowers of the Loan Documents or the
borrowings by the Borrowers thereunder.

     6. To our actual knowledge, there is no action, suit, proceeding,
governmental investigation or arbitration pending or threatened against the
Borrowers before any court or arbitrator, any governmental or administrative
body, agency or official, or any self-regulatory organization which (a)
challenges the validity, or seeks to enjoin the performance of, any Loan
Document or (b) could reasonably be expected to have a Material Adverse Effect.

     7. Neither Borrower is an "investment company" or a company "controlled" by
an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

     8. Neither Borrower is a "holding company" or a "subsidiary company" of a
"holding company" or an "affiliate" of a "holding company" within the meaning of
the Public Utility Holding Company Act of 1935, as amended.

     9. The rates of interest provided in the Credit Agreements do not violate
any laws of the State of Illinois relating to interest or usury.

     This opinion is limited to the laws of the State of Illinois, the General
Corporation Law of the State of Delaware and the federal laws of the United
States of America.

     The foregoing opinions are subject to and qualified by the effect of any
requirement that the Agent or the Lenders take certain actions or make certain
determinations in a commercially reasonable manner and in good faith. Moreover,
we express no opinion as to the enforceability of (a) any waiver of the right to
a jury trial, (b) any provision requiring the payment of interest on interest,
(c) express or implicit waivers of broad or vaguely stated rights, unknown
future rights, defenses to obligations or rights granted by law, where such
waivers are against public policy or prohibited by law, or (d) indemnity and
contribution rights that may be against public policy.

     This opinion speaks as of the time of its delivery on the date it bears. We
do not assume any obligation to provide you with any subsequent opinion or
advice by reason of any fact about which we did not have actual knowledge at
that time, by reason of any change subsequent to that time in any law covered by
any of our opinions, or for any other reason.

     This opinion is for the benefit of the Agent and the Lenders and their
permitted assignees in connection with the transactions contemplated by the Loan
Documents and may not be relied


                              Exhibit D-1, Page 3

upon by any other Person or for any other purpose, or delivered to any other
Person for any purpose, without our prior written consent.

                               Very truly yours,

Ladies and Gentlemen:

     I am Senior Vice President and General Counsel of each of the Borrowers,
and have represented the Borrowers in connection with the Credit Agreements.
This opinion is delivered to you responsive to Section 4.1(d) of the Credit
Agreements. Capitalized terms used herein and not otherwise defined have the
meanings ascribed in the Credit Agreements. The Credit Agreements and the Notes
of the Borrowers delivered in connection therewith are referred to herein as the
"Loan Documents." The following subsidiaries of Nuveen are hereinafter
collectively referred to as the "Subsidiaries," with each referred to as a
"Subsidiary": Nuveen Investments; Nuveen/Flagship Acquisition Corporation, a
Delaware corporation; Nuveen Senior Loan Asset Management, Inc., a Delaware
corporation; Rittenhouse Financial Services, Inc., a Delaware corporation;
Nuveen Advisory Corp., a Delaware corporation; Nuveen Institutional Advisory
Corp., a Delaware corporation; and Nuveen Asset Management Inc., a Delaware
corporation.


                              Exhibit D-2, Page 1


<PAGE>   94


     I have examined executed counterparts of the Credit Agreements and
originals of the Notes, if any. I also have examined originals, or copies
certified or otherwise identified to my satisfaction, of such agreements,
corporate records, instruments, certificates of public officials and corporate
officers and such matters of law as I deemed necessary for purposes of this
opinion. For purposes of my opinions as to corporate existence, good standing
and qualification as a foreign corporation in paragraph 1, I have relied
exclusively upon certificates issued by a governmental authority in each
relevant jurisdiction and such opinions are not intended to provide any
conclusion or assurance beyond that conveyed by those certificates.

     I have assumed the genuineness of all signatures, the legal capacity of all
individuals who have executed the Loan Documents and all other documents I have
reviewed, the authenticity of all documents submitted to me as originals and the
conformity to original documents of all documents submitted to me as copies.

     Based upon the foregoing, and subject to the qualifications stated herein,
I am of the opinion that:

     1. Each of the Borrowers and each Subsidiary is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. Nuveen is duly qualified, in good standing and authorized to conduct
business as a foreign corporation in the jurisdictions specified in the attached
Schedule II. Nuveen Investments is duly qualified, in good standing and
authorized to conduct business as a foreign corporation under the name John
Nuveen & Co. Incorporated in the jurisdictions specified in the attached
Schedule II and is in the process of changing its name to Nuveen Investments in
accordance with applicable corporations law. Nuveen Investments is registered
with the SEC as a broker-dealer under the Securities Exchange Act of 1934, as
amended, and is a member of the NASD. Each Subsidiary other than Nuveen
Investments and Nuveen/Flagship Acquisition Corporation is registered with the
SEC as an investment adviser under the Advisers Act.

     2. The execution, delivery and performance by each Borrower of the Loan
Documents to which is a party do not (a) violate any law, rule or regulation
(including Regulations T, U and X of the Board of Governors of the Federal
Reserve System) applicable to such Borrower or any Subsidiary or any order,
writ, judgment, decree, determination or award known to me that is presently in
effect and binding on such Borrower or any Subsidiary, (b) conflict with or
result in a breach of, or constitute a default under, the certificate of
incorporation or by-laws of such Borrower or any Subsidiary, (c) conflict with
or result in a breach of, or constitute a default under, or result in or require
the creation or imposition of any Lien on any of the properties now owned by
such Borrower or any Subsidiary, under any indenture, credit agreement, material
lease or other material agreement or instrument to which such Borrower or any
Subsidiary is a party or by which they or any or their property is bound.


                              Exhibit D-2, Page 2


<PAGE>   95



     3. No authorization, consent, approval, license, qualification or formal
exemption from, or filing, declaration or registration with, any Governmental
Authority, self-regulatory organization or securities exchange is required in
connection with the execution, delivery or performance by the Borrowers of the
Loan Documents.

     4. There is no action, suit, proceeding, governmental investigation or
arbitration pending or, to my knowledge, overtly threatened against the
Borrowers or any Subsidiary or any of their respective material properties
before any court or arbitrator, any governmental or administrative body, agency
or official, or any self-regulatory organization which (a) challenges the
validity, or seeks to enjoin the performance of, any Loan Document or (b) could
reasonably be expected to have a Material Adverse Effect.

     This opinion is limited to the laws of the State of Illinois, the General
Corporation Law of the State of Delaware and the federal laws of the United
States of America.

     This opinion speaks as of the time of its delivery on the date it bears. I
do not assume any obligation to provide you with any subsequent opinion or
advice by reason of any fact about which I did not have actual knowledge at that
time, by reason of any change subsequent to that time in any law covered by any
of my opinions, or for any other reason.

     This opinion is for the benefit of the Agent, the Lenders and their
permitted assignees in connection with the transactions contemplated by the Loan
Documents and may not be relied upon by any other Person, other than Gardner,
Carton & Douglas, or for any other purpose, or delivered to any other Person for
any purpose, without my prior written consent.
