          Revolving Loan Borrowing consisting of Base Rate Loans; or (B)
          $2,000,000 or an integral multiple of $1,000,000 in excess thereof in
          the case of a Revolving Loan Borrowing consisting of LIBOR Loans;

               (ii)  Type.  Whether the requested Revolving Loan Borrowing is to

                                       21
<PAGE>

     Revolving Loan Borrowing consisting of Base Rate Loans. Each Notice of
     Revolving Loan Borrowing shall be delivered by first-class mail or
     facsimile to Agent at the office or facsimile number and during the hours
     specified in Paragraph 8.01; provided, however, that Borrower shall
                  --------------  --------  -------
     promptly deliver to Agent the original of any Notice of Revolving Loan
     Borrowing initially delivered by facsimile. Agent shall promptly notify
     each Lender of the contents of each Notice of Revolving Loan Borrowing and
     of the amount and Type of (and, if applicable, the Interest Period for)
     each Revolving Loan to be made by such Lender as part of the requested
     Revolving Loan Borrowing.

          (c)  Revolving Loan Interest Rates.  Borrower shall pay interest on
     the unpaid principal amount of each Revolving Loan from the date of such
     Revolving Loan until the maturity thereof, at one of the following rates
     per annum:

               (i)   Base Rate Loans.  During such periods as such Revolving
                     ---------------
          Loan is a Base Rate Loan, at a rate per annum equal to the Base Rate
          plus the Applicable Margin therefor, such rate to change from time to
          ----
          time as the Applicable Margin or Base Rate shall change; and

               (ii)  LIBOR Loans.  During such periods as such Revolving Loan is
                     -----------
          a LIBOR Loan, at a rate per annum equal at all times during each
          Interest Period for such LIBOR Loan to the LIBO Rate for such Interest
          Period plus the Applicable Margin for such Revolving Loan (or in the
                 ----
          case of any LIBOR Loan having an Interest Period of less than one (1)
          month, the then applicable Rate for one (1) month LIBOR Loans
          available on such date plus the Applicable Margin for such Revolving
          Loan), such rate to change from time to time during such Interest
          Period as the Applicable Margin shall change.  (The Applicable Margins
          for LIBOR Loans shall be determined as provided in the Pricing Grid
          and may change for each Margin Period.)

     All Revolving Loans in each Revolving Loan Borrowing shall, at any given
     time prior to maturity, bear interest at one, and only one, of the above
     rates. The number of Revolving Loan Borrowings consisting of LIBOR Loans
     shall not exceed five (5) at any time.

          (d)  Conversion of Revolving Loans. Borrower may convert any
     Revolving Loan Borrowing from one Type of Revolving Loan Borrowing to the
     other Type; provided, however, that any conversion of a Revolving Loan
     Borrowing consisting of LIBOR Loans into a Revolving Loan Borrowing
     consisting of Base Rate Loans shall be made on, and only on, the last day
     of an Interest Period for such LIBOR Loans.  Borrower shall request such a
     conversion by an irrevocable written notice to Agent in the form of Exhibit
     B-1, appropriately completed (a "Notice of Revolving Loan Conversion"),
     which specifies, among other things:

               (i)   The Revolving Loan Borrowing which is to be converted;

                                       22
<PAGE>

               (ii)  The Type of Revolving Loan Borrowing into which such
          Revolving Loan Borrowing is to be converted;

               (iii) If such Revolving Loan Borrowing is to be converted into a
          Revolving Loan Borrowing consisting of LIBOR Loans, the initial
          Interest Period selected by Borrower for such LIBOR Loans in
          accordance with Subparagraph 2.01(e); and

               (iv)  The date of the requested conversion, which shall be a
          Business Day.

     Borrower shall give each Notice of Revolving Loan Conversion to Agent at
     least three (3) Business Days in the case of a conversion to a LIBOR Loan
     or one (1) Business Day in the case of a conversion to a Base Rate Loan
     before the date of the requested conversion.  Each Notice of Revolving Loan
     Conversion shall be delivered by first-class mail or facsimile to Agent at
     the office or to the facsimile number and during the hours specified in
     Paragraph 8.01; provided, however, that Borrower shall promptly deliver to
     Agent the original of any Notice of Revolving Loan Conversion initially
     delivered by facsimile.  Agent shall promptly notify each Lender of the
     contents of each Notice of Revolving Loan Conversion.

          (e)  LIBOR Loan Interest Periods.

               (i)   The initial and each subsequent Interest Period selected by
          Borrower for a LIBOR Loan shall be one (1), two (2), three (3) or six
          (6) months (or with the consent of each Lender from time to time, any
          period of days seven (7) or greater but less than one (1) month);
          provided, however, that (i) any Interest Period which would otherwise
          --------  -------
          end on a day which is not a Business Day shall be extended to the next
          succeeding Business Day unless such next Business Day falls in another
          calendar month, in which case such Interest Period shall end on the
          immediately preceding Business Day; (ii) any Interest Period (other
          than an Interest Period which is less than one (1) month) which begins
          on the last Business Day of a calendar month (or on a day for which
          there is no numerically corresponding day in the calendar month at the
          end of such Interest Period) shall end on the last Business Day of a
          calendar month; and (iii) no Interest Period shall end after the
          Revolving Loan Maturity Date.

               (ii)  Borrower shall notify Agent by an irrevocable written
          notice in the form of Exhibit C-1, appropriately completed (a "Notice
                                -----------
          of Revolving Loan Interest Period Selection"), at least three (3)
          Business Days prior to the last day of each Interest Period for a
          Revolving Loan Borrowing consisting of LIBOR Loans of the Interest
          Period selected by Borrower for the next succeeding Interest Period
          for such LIBOR Loans. Each Notice of Revolving Loan Interest Period
          Selection shall be given by first-class mail or facsimile to the
          office or the facsimile number and during the hours specified in
          Paragraph 8.01; provided, however, that Borrower shall promptly
          --------------  --------  -------

                                       23
<PAGE>

          deliver to Agent the original of any Notice of Revolving Loan Interest
          Period Selection initially delivered by facsimile. If Borrower fails
          to notify Agent of the next Interest Period for a Revolving Loan
          Borrowing consisting of LIBOR Loans in accordance with this
          Subparagraph 2.01(e), such LIBOR Loans shall automatically convert to
          Base Rate Loans on the last day of the current Interest Period
          therefor.

          (f)  Scheduled Revolving Loan Payments.  Borrower shall repay the
     principal amount of the Revolving Loans on the Revolving Loan Maturity
     Date; provided, however, that Borrower may repay the Revolving Loans from
     the proceeds of the Term Loans made to Borrower on the Revolving Loan
     Maturity Date.   Borrower shall pay accrued interest on the unpaid
     principal amount of each Revolving Loan in arrears (i) in the case of a
     Base Rate Loan, on the last day in each calendar quarter, (ii) in the case
     of a LIBOR Loan, on the last day of each Interest Period therefor (and, (A)
     if any such Interest Period is longer than three (3) months, every three
     (3) months, or (B) if any such Interest Period is shorter than one (1)
     month, every month); and (iii) in the case of all Revolving Loans, upon
     prepayment (to the extent thereof) and at maturity.

          (g)  Purpose.  Borrower shall use the proceeds of the Revolving Loans,
     first, to repay on the Closing Date all Indebtedness outstanding under the
     Credit Agreement dated as of March 28, 1997 among Borrower, the lending
     institutions party thereto and ABN AMRO Bank N.V. as agent for such lending
     institutions (as amended from time to time, the "Prior Credit Agreement")
                                                      ----------------------
     and, thereafter, for Borrower's general corporate needs.

          (h)  Revolving Loan Maturity Date Extensions.  On or before sixty (60)
     days prior to the Revolving Loan Maturity Date (or the first Business Day
     thereafter if such day is not a Business Day), Borrower may request the
     Lenders to extend the Revolving Loan Maturity Date then in effect for an
     additional 364-day period by delivering a written request to Agent (each
     such written request, an "Extension Request").  Agent shall promptly
     deliver to each Lender a copy of any such Extension Request received by
     Agent.  If a Lender, in its sole and absolute discretion, consents to any
     Extension Request, such Lender shall so notify Agent in writing not later
     than thirty-five (35) days prior to the Revolving Loan Maturity Date.  Any
     failure by any Lender so to notify Agent shall be deemed a denial thereof.
     (Borrower acknowledges and agrees that no Lender has promised, either
     expressly or impliedly, or has any obligation or commitment, to consent to
     such an Extension Request at any time.)  If all Lenders consent to an
     Extension Request, Agent shall so notify Borrower and the Lenders and shall
     prepare an amendment to reflect the requested extension.  If no Lender or
     less than all Lenders shall consent to an Extension Request, Agent shall so
     notify Borrower and the Lenders, and the Revolving Loan Maturity Date then
     in effect shall remain in effect.

     2.02.     Term Loan Facility.

          (a)  Term Loan Availability. Subject to the terms and conditions of
     this Agreement, each Lender severally agrees to advance to Borrower on the
     Revolving Loan Maturity Date a term loan in such amount as Borrower may
     request under this Paragraph 2.02 (individually, a "Term Loan"); provided,
     however, that the aggregate principal amount of the Term Loan made by such
     Lender shall not exceed the lesser of (i) such Lender's Commitment at such
     time and (ii) the aggregate principal amount of all Revolving Loans payable
     to such Lender on such date.  The Term Loans shall be made on a pro rata
     basis by the Lenders in accordance with their respective Proportionate
     Shares, with the Term Loan Borrowing to be comprised of a Term Loan by each
     Lender equal to such Lender's Proportionate Share of the Term Loan
     Borrowing.  Borrower may not reborrow the principal amount of a Term Loan
     after repayment or prepayment thereof.

          (b)  Notice of Term Loan Borrowing.  Borrower shall request the Term
     Loan Borrowing by delivering to Agent an irrevocable written notice in the
     form of Exhibit A-2, appropriately completed (a "Notice of Term Loan
     Borrowing"), which specifies, among other things:

               (i)   Amount.  The principal amount of the Term Loan Borrowing,
          which shall be in a minimum amount equal to all of the Revolving Loans
          outstanding on the Revolving Loan Maturity Date;

               (ii)  Type.  (A) The principal portion of the Term Loan Borrowing
          which is to be a Base Rate Portion and (B) the principal portion(s) of
          the Term Loan Borrowing which is (are) to be a LIBOR Portion(s); and

               (iii) Interest Period. If any Portion of the Term Loan Borrowing
          is initially to be a LIBOR Portion, the initial Interest Period
          selected by Borrower for each such Portion in accordance with
          Subparagraph 2.02(e).

     Borrower shall give the Notice of Term Loan Borrowing to Agent not later
     than the thirty (30) days prior to the Revolving Loan Maturity Date.  The
     Notice of Term Loan Borrowing shall be delivered by first-class mail or
     facsimile to Agent at the office or facsimile number and during the hours
     specified in Paragraph 8.01; provided, however, that Borrower shall
     promptly deliver to Agent the original of the Notice of Term Loan Borrowing
     if initially delivered by facsimile.  Agent shall promptly notify each
     Lender of the contents of the Notice of Term Loan Borrowing.

          (c)  Term Loan Interest Rates.  Borrower shall pay interest on the
     unpaid principal amount of each Term Loan from the date of such Term Loan
     until the maturity thereof, at the following rates per annum:

               (i) Base Rate Portions.  During such periods as any Portion of
          such Term Loan is a Base Rate Portion, at a rate per annum on such
          Portion

                                       25
<PAGE>

          equal to the Base Rate plus the Applicable Margin therefor, such rate
          to change from time to time as the Applicable Margin or Base Rate
          shall change; and

               (ii)  LIBOR Portions.  During such periods as any Portion of such
          Term Loan is a LIBOR Portion, at a rate per annum on such Portion
          equal at all times during each Interest Period for such Portion to the
          LIBO Rate for such Interest Period plus the Applicable Margin (or in
          the case of any LIBOR Portion having an Interest Period of less than
          one (1) month, the then applicable Rate for one (1) month LIBOR
          Portions available on such date plus the Applicable Margin for such
          Portion), such rate to change from time to time during such Interest
          Period as the Applicable Margin shall change.  (The Applicable Margins
          for LIBOR Portions shall be determined as provided in the Pricing Grid
          and may change for each Margin Period.)

     Each LIBOR Portion of the Term Loan Borrowing shall be in a minimum amount
     of $500,000 or an integral multiple of $250,000 in excess thereof.  The
     number of LIBOR Portions of the Term Loan Borrowing shall not exceed five
     (5) at any time.

          (d)  Conversion of Term Loan Portions.  Borrower may convert any
     Portion of the Term Loan Borrowing from one Type of Portion to another
     Type; provided, however, that any conversion of a LIBOR Portion into
     another LIBOR Portion or a Base Rate Portion shall be made on, and only on,
     the last day of an Interest Period for such LIBOR Portion.  Borrower shall
     request such a conversion by an irrevocable written notice to Agent in the
     form of Exhibit B-2, appropriately completed (a "Notice of Term Loan
     Conversion"), which specifies, among other things:

               (i)   The Portion of the Term Loan Borrowing which is to be
          converted;

               (ii)  The amount and Type of each Portion of the Term Loan
          Borrowing into which it is to be converted;

               (iii) If any Portion of the Term Loan Borrowing is to be
          converted into a LIBOR Portion, the initial Interest Period selected
          by Borrower for such Portion in accordance with Subparagraph 2.02(e);
          and

               (iv)  The date of the requested conversion, which shall be a
          Business Day.

     Borrower shall give each Notice of Term Loan Conversion to Agent at least
     three (3) Business Days in the case of a conversion to a LIBOR Portion and
     one (1) Business Day in the case of a conversion to a Base Rate Portion
     before the date of the requested conversion.  Each Notice of Term Loan
     Conversion shall be delivered by first-class mail or facsimile to Agent at
     the office or to the facsimile number and

                                       26
<PAGE>

     during the hours specified in Paragraph 8.01; provided, however, that
     Borrower shall promptly deliver to Agent the original of any Notice of Term
     Loan Conversion initially delivered by facsimile. Agent shall promptly
     notify each Lender of the contents of each Notice of Term Loan Conversion.

          (e)  LIBOR Portion Interest Periods.

               (i) The initial and each subsequent Interest Period selected by
          Borrower for a LIBOR Portion of the Term Loan Borrowing shall be one
          (1), two (2), three (3) or six (6) months (or with the consent of each
          Lender from time to time, any period of days seven (7) or greater but
          less than one (1) month); provided, however, that (A) any Interest
          Period which would otherwise end on a day which is not a Business Day
          shall be extended to the next succeeding Business Day unless such next
          Business Day falls in another calendar month, in which case such
          Interest Period shall end on the immediately preceding Business Day;
          (B) any Interest Period (other than an Interest Period which is less
          than one (1) month) which begins on the last Business Day of a
          calendar month (or on a day for which there is no numerically
          corresponding day in the calendar month at the end of such Interest
          Period) shall end on the last Business Day of a calendar month; (C) no
          Interest Period shall end after a Term Loan Installment Date unless,
          after giving effect to such Interest Period, the aggregate principal
          amount of all Base Rate Portions and all LIBOR Portions having
          Interest Periods ending on or prior to such Term Loan Installment Date
          equals or exceeds the principal payment due on such Term Loan
          Installment Date; and (D) no Interest Period shall end after the Term
          Loan Maturity Date.

               (ii) Borrower shall notify Agent by an irrevocable written notice
          in the form of Exhibit C-2, appropriately completed (a "Notice of Term
          Loan Interest Period Selection"), at least three (3) Business Days
          prior to the last day of each Interest Period for a LIBOR Portion of
          the Term Loan Borrowing of the Interest Period selected by Borrower
          for the next succeeding Interest Period for such Portion.  Each Notice
          of Term Loan Interest Period Selection shall be given by first-class
          mail or facsimile to the office or the facsimile number and during the
          hours specified in Paragraph 8.01; provided, however, that Borrower
          shall promptly deliver to Agent the original of any Notice of Term
          Loan Interest Period Selection initially delivered by facsimile.  If
          Borrower fails to notify Agent of the next Interest Period for a LIBOR
          Portion of the Term Loan Borrowing in accordance with this
          Subparagraph 2.03(e), such Portion shall automatically convert to a
          Base Rate Portion on the last day of the current Interest Period
          therefor.

          (f)  Scheduled Term Loan Payments.  Borrower shall repay the principal
     amount of the Term Loans in four equal quarterly installments, payable on
     the last Business Day of each March, June, September and December, as
     applicable (commencing on the first such day to occur after the Revolving
     Loan Maturity Date

                                       27
<PAGE>

     and ending on the Term Loan Maturity Date) (each such date to be referred
     to herein as a "Term Loan Installment Date"); provided, however, that the
     principal payment due on the Term Loan Maturity Date shall be in the amount
     necessary to pay all remaining unpaid principal on the Term Loans. Borrower
     shall pay accrued interest on the unpaid principal amount of each Term Loan
     in arrears (i) in the case of a Base Rate Portion, on the last Business Day
     in each quarter, as applicable, (ii) in the case of a LIBOR Portion, on the
     last day of each Interest Period (and (A) if any such Interest Period is
     equal to or longer than three (3) months, every three (3) months, or (B) if
     any such Interest Period is shorter than one (1) month, every month); and
     (iii) in the case of all Term Loans, upon prepayment (to the extent
     thereof) and at maturity.

          (g)  Purpose.  Borrower shall use the proceeds of the Term Loans first
     to repay the Revolving Loans and, thereafter, for Borrower's general
     corporate needs.

     2.03.     Commitment Reductions, Etc.
               --------------------------

          (a)  Reduction or Cancellation of Commitments.  Borrower may, upon
               ----------------------------------------
     three (3) Business Days written notice to Agent, permanently reduce the
     Total Commitment by the amount of five million Dollars ($5,000,000) or an
     integral multiple of one million Dollars ($1,000,000) in excess thereof or
     cancel the Total Commitment in its entirety; provided, however, that:
                                                  -------- --------

               (i) Borrower may not reduce the Total Commitment prior to the
          Revolving Loan Maturity Date, if, after giving effect to such
          reduction, the aggregate principal amount of all Loans then
          outstanding would exceed the Total Commitment; and

               (ii) Borrower may not cancel the Total Commitment prior to the
          Revolving Loan Maturity Date, if, after giving effect to such
          cancellation, any Loan would then remain outstanding.

          (b)  Effect of Commitment Reductions.  From the effective date of any
               -------------------------------
     reduction of the Total Commitment, the Commitment Fees payable pursuant to
     Subparagraph  2.04(c) shall be computed on the basis of the Total
     ---------------------
     Commitment as so reduced.  Once reduced or cancelled, the Total Commitment
     may not be increased or reinstated without the prior written consent of all
     Lenders.  Any reduction of the Total Commitment pursuant to Subparagraph
                                                                 -------------
     2.03(a) shall be applied ratably to reduce each Lender's Commitment in
     -------
     accordance with clause (i) of Subparagraph  2.09(a).
                     -----------------------------------

      2.04.    Fees.
               ----

          (b)  Participation Fees.  Borrower shall pay to Agent, for the ratable
               ------------------
     benefit of the Lenders as provided in this Subparagraph 2.04(b),
                                                --------------------
     nonrefundable participation fees (the "Participation Fees") in amounts
                                            ------------------
     equal to five one hundredths of one percent (.05%) of such Lender's
     Proportionate Share of the Total Commitment on the Closing Date.

          (c)  Commitment Fees.  Borrower shall pay to Agent, for the ratable
               ---------------
     benefit of the Lenders as provided in clause (iv) of Subparagraph  2.09(a),
     commitment fees (the "Commitment Fees") equal to the Commitment Fee
                           ---------------
     Percentage on the daily average Unused Commitment for the period beginning
     on the date of this Agreement and ending on the Revolving Loan Maturity
     Date. (The Commitment Fee Percentage shall be determined as provided in the
     Pricing Grid and may change for each Margin Period.) Borrower shall pay the
     Commitment Fees in arrears on the last day in each March, June, September
     and December (commencing June 30, 1999) and on the Revolving Loan Maturity
     Date (or if the Total Commitment is cancelled on a date prior to the
     Revolving Loan Maturity Date, on such prior date).

      2.05.    Prepayments.
               -----------

          (a)  Terms of all Prepayments.  Upon the prepayment of any Loan
               ------------------------
     (whether such prepayment is an optional prepayment under Subparagraph
     2.05(b), a mandatory prepayment required by Subparagraph  2.05(c) or a
     mandatory prepayment required by any other provision of this Agreement or
     the other Credit Documents, including, without limitation, a prepayment
     upon acceleration), Borrower shall pay to the Lender which made such Loan
     (i) all accrued interest to the date of such prepayment on the amount
     prepaid and (ii) if such prepayment is the prepayment of a LIBOR Loan or
     LIBOR Portion on a day other than the last day of an Interest Period for
     such LIBOR Loan or LIBOR Portion, all amounts payable to such Lender
     pursuant to Paragraph  2.12.

          (b)  Optional Prepayments.  At its option, Borrower may, upon three
               --------------------
     (3) Business Days notice to Agent, prepay the Loans in any Borrowing in
     part, in an aggregate principal amount of $2,000,000 or more, or in whole.

          (c)  Mandatory Prepayments. If, at any time, the aggregate principal
               ---------------------
     amount of all Loans then outstanding exceeds the Total Commitment at such
     time, Borrower shall immediately prepay Loans in an aggregate principal
     amount equal to such excess.

          (d)  Application of Term Loan Prepayments.  All prepayments which are
     applied to reduce the principal amount of the Term Loans shall reduce the
     aggregate principal amount payable by Borrower on the then remaining Term
     Loan Installment Dates in inverse order commencing with the Term Loan
     Maturity Date.  Without modifying the order of application of Term Loan
     prepayments set forth in the preceding sentence, all such prepayments
     shall, to the extent possible, be first

                                       29
<PAGE>

     applied to prepay Base Rate Portions and then if any funds remain, to
     prepay LIBOR Portions.

     2.06.     Other Payment Terms.
               -------------------

          (a)  Place and Manner.  Borrower shall make all payments due to each
               ----------------
     Lender or Agent hereunder by payments to Agent at Agent's office located at
     the address specified in Paragraph 8.01, with each payment due to a Lender
                              --------------
     to be for the account of such Lender and such Lender's Applicable Lending
     Office.  Borrower shall make all payments hereunder in lawful money of the
     United States and in same day or immediately available funds not later than
     2:00 p.m. on the date due.  Agent shall promptly disburse to each Lender
     each payment received by Agent for the account of such Lender.


          (b)  Date.  Whenever any payment due hereunder shall fall due on a day
               ----
     other than a Business Day, such payment shall be made on the next
     succeeding Business Day, and such extension of time shall be included in
     the computation of interest or fees, as the case may be.

          (c)  Late Payments.  If any amounts required to be paid by Borrower
               -------------
     under this Agreement or the other Credit Documents (including, without
     limitation, principal or interest payable on any Loan, any fees or other
     amounts) remain unpaid after such amounts are due, Borrower shall pay
     interest on the aggregate, outstanding balance of such amounts from the
     date due until those amounts are paid in full at a per annum rate equal to
     the Base Rate plus two percent (2.0%), such rate to change from time to
     time as the Base Rate shall change.

          (d)  Application of Payments.  All payments hereunder shall be applied
               -----------------------
     first to unpaid fees, costs and expenses then due and payable under this
     Agreement or the other Credit Documents, second to accrued interest then
     due and payable under this Agreement or the other Credit Documents and
     finally to reduce the principal amount of outstanding Loans.

          (e)  Failure to Pay Agent.  Unless Agent shall have received notice
               --------------------
     from Borrower at least one (1) Business Day prior to the date on which any
     payment is due to the Lenders hereunder that Borrower will not make such
     payment in full, Agent shall be entitled to assume that Borrower has made
     or will make such payment in full to Agent on such date and Agent may, in
     reliance upon such assumption, cause to be paid to the Lenders on such due
     date an amount equal to the amount then due such Lenders.  If and to the
     extent Borrower shall not have so made such payment in full to Agent, each
     such Lender shall repay to Agent forthwith on demand such amount
     distributed to such Lender together with interest thereon, for each day
     from the date such amount is distributed to such Lender until the date such
     Lender repays such amount to Agent, at (i) the Federal Funds Rate for the
     first three (3) days and (ii) the per annum rate applicable to Base Rate
     Loans thereafter.  A certificate of Agent submitted to any Lender with
     respect to any

                                       30
<PAGE>

     amounts owing by such Lender under this Subparagraph 2.10(e) shall be
                                             --------------------
     conclusive absent manifest error.

     2.07.  Notes and Interest Account.
            --------------------------

            (a)   Revolving Loan Notes.  The obligation of Borrower to repay the
                  --------------------
     Revolving Loans made by each Lender and to pay interest thereon at the
     rates provided herein shall be evidenced by a promissory note in the form
     of Exhibit D-1 (individually, a "Revolving Loan Note") which Revolving
        -----------                   -------------------
     Loan Note shall be (i) payable to the order of such Lender, (ii) in the
     amount of such Lender's Commitment, (iii) dated the Closing Date and (iv)
     otherwise appropriately completed. Borrower authorizes each Lender to
     record on the schedule annexed to such Lender's Revolving Loan Note the
     date and amount of each Revolving Loan made by such Lender and of each
     payment or prepayment of principal thereon made by Borrower, and agrees
     that all such notations shall constitute prima facie evidence of the
     matters noted; provided, however, that any failure by a Lender to make any
                    -------- --------
     such notation shall not affect the Obligations. Borrower further authorizes
     each Lender to attach to and make a part of such Lender's Revolving Loan
     Note continuations of the schedule attached thereto as necessary.

            (b)   Term Loan Notes. The obligation of Borrower to repay the Term
                  ---------------
     Loans shall be evidenced by a promissory note in the form of Exhibit D-2
                                                                  -----------
     (individually, a "Term Loan Note") which note shall be (i) payable to the
                       --------------
     order of such Lender, (ii) in the amount of such Lender's Term Loan, (iii)
     dated the date of the Term Loan Borrowing and (iv) otherwise appropriately
     completed.

            (c)   Interest Account. Borrower authorizes Agent to record in an
                  ----------------
     account or accounts maintained by Agent on its books (the "Interest
                                                                --------
     Account") (i) the interest rates applicable to all Loans and the effective
     -------
     dates of all changes thereto, (ii) the Interest Period for each LIBOR Loan,
     (iii) the date and amount of each principal and interest payment on each
     Loan and (iv) such other information as Agent may determine is necessary
     for the computation of interest payable by Borrower hereunder.

     2.08.  Loan Funding.
            ------------

            (a)   Lender Funding and Disbursement to Borrower. Each Lender
                  ------------------------------------------
     shall, before 2:00 p.m. on the date of each Borrowing, make available to
     Agent at Agent's office specified in Paragraph 8.01, in same day or
                                          --------------
     immediately available funds, such Lender's Proportionate Share of such
     Borrowing. After Agent's receipt of such funds and upon satisfaction of the
     applicable conditions set forth in Section III, Agent shall promptly
                                        -----------
     disburse such funds to Borrower in same day or immediately available funds.
     Unless otherwise directed by Borrower, Agent shall disburse the proceeds of
     each Borrowing by disbursement to the account or accounts specified in the
     applicable Notice of Borrowing. The proceeds of the Term Loan Borrowing
     shall be applied to repay the Revolving Loans and shall be disbursed
     directly to the Lenders.

                                       31
<PAGE>

            (b)   Lender Failure to Fund. Unless Agent shall have received
                  ----------------------
     notice from a Lender prior to the date of any Borrowing that such Lender
     will not make available to Agent such Lender's Proportionate Share of such
     Borrowing, Agent shall be entitled to assume that such Lender has made or
     will make such portion available to Agent on the date of such Borrowing in
     accordance with Subparagraph 2.08(a), and Agent may on such date, in
                     --------------------
     reliance upon such assumption, disburse or otherwise credit to Borrower a
     corresponding amount. If any Lender does not make the amount of its
     Proportionate Share of any Borrowing available to Agent on or prior to the
     date of such Borrowing, such Lender shall pay to Agent, on demand, interest
     which shall accrue on such amount from the date of such Borrowing until
     such amount is paid to Agent at rates equal to (i) the daily Federal Funds
     Rate during the period from the date of such Borrowing through the third
     Business Day thereafter and (ii) the rate applicable to Base Rate Loans
     thereafter. A certificate of Agent submitted to any Lender with respect to
     any amounts owing under this Subparagraph 2.08(b) shall be conclusive
                                  --------------------
     absent manifest error. If the amount of any Lender's Proportionate Share of
     any Borrowing is not paid to Agent by such Lender within three (3) Business
     Days after the date of such Borrowing, Borrower shall repay such amount to
     Agent, on demand, together with interest thereon, for each day from the
     date such amount was disbursed to Borrower until the date such amount is
     repaid to Agent, at the interest rate applicable at the time to the Loans
     comprising such Borrowing.

            (c)   Lenders' Obligations Several. The failure of any Lender to
                  ----------------------------
     make the Loan to be made by it as part of any Borrowing shall not relieve
     any other Lender of its obligation hereunder to make its Loan on the date
     of such Borrowing, but no Lender shall be obligated in any way to make any
     Loan which another Lender has failed or refused to make or otherwise be in
     any way responsible for the failure or refusal of any other Lender to make
     any Loan required to be made by such other Lender on the date of any
     Borrowing.

     2.09.  Pro Rata Treatment.
            ------------------

            (a)   Borrowings, Commitment Reductions, Etc. Except as otherwise
                  ---------------------------------------
     provided herein:

                  (i)    Each Borrowing and reduction of the Total Commitment
            shall be made or shared among the Lenders pro rata according to
            their respective Proportionate Shares;

                  (ii)   Each payment of principal of Loans in any Borrowing
            shall be shared among the Lenders which made or funded the Loans in
            such Borrowing pro rata according to the respective unpaid principal
            amounts of such Loans so made or funded by such Lenders;

                                       32
<PAGE>

                  (iii)  Each payment of interest on Loans in any Borrowing
            shall be shared among the Lenders which made or funded the Loans in
            such Borrowing pro rata according to (A) the respective unpaid
            principal amounts of such Loans so made or funded by such Lenders
            and (B) the dates on which such Lenders so made or funded such
            Loans;

                  (iv)   Each payment of Commitment Fees shall be shared among
            the Lenders (except for Defaulting Lenders) pro rata according to
            (A) their respective Proportionate Shares and (B) in the case of
            each Lender which becomes a Lender hereunder after the date hereof,
            the date upon which such Lender so became a Lender;

                  (v)    Each payment of interest (other than interest on Loans)
            shall be shared among the Lenders and Agent owed the amount upon
            which such interest accrues pro rata according to (A) the respective
            amounts so owed such Lenders and Agent and (B) the dates on which
            such amounts became owing to such Lenders and Agent; and

                  (vi)   All other payments under this Agreement and the other
            Credit Documents shall be for the benefit of the Person or Persons
            specified.

            (b)   Sharing of Payments, Etc. If any Lender shall obtain any
                  ------------------------
     payment (whether voluntary, involuntary, through the exercise of any right
     of setoff, or otherwise) on account of Loans owed to it in excess of its
     ratable share of payments on account of such Loans obtained by all Lenders
     entitled to such payments, such Lender shall forthwith purchase from the
     other Lenders such participations in the Loans as shall be necessary to
     cause such purchasing Lender to share the excess payment ratably with each
     of them; provided, however, that if all or any portion of such excess
              --------  -------
     payment is thereafter recovered from such purchasing Lender, such purchase
     shall be rescinded and each other Lender shall repay to the purchasing
     Lender the purchase price to the extent of such recovery together with an
     amount equal to such other Lender's ratable share (according to the
     proportion of (i) the amount of such other Lender's required repayment to
     (ii) the total amount so recovered from the purchasing Lender) of any
     interest or other amount paid or payable by the purchasing Lender in
     respect of the total amount so recovered. Borrower agrees that any Lender
     so purchasing a participation from another Lender pursuant to this
     Subparagraph 2.09(b) may, to the fullest extent permitted by law, exercise
     --------------------
     all its rights of payment (including the right of setoff) with respect to
     such participation as fully as if such Lender were the direct creditor of
     Borrower in the amount of such participation.

     2.10.  Change of Circumstances.
            -----------------------

            (a)   Inability to Determine Rates. If, on or before the first day
                  ----------------------------
     of any Interest Period for any LIBOR Loan or LIBOR Portion, Agent shall
     determine that (i) the LIBO Rate for such Interest Period cannot be
     adequately and reasonably determined due to the unavailability of funds in
     or other circumstances affecting the London interbank market

                                       33
<PAGE>

     or (ii) the rate of interest for such LIBOR Loan or LIBOR Portion, as the
     case may be, does not adequately and fairly reflect the cost to any Lender
     of making or maintaining such LIBOR Loan or LIBOR Portion, Agent shall
     immediately give notice of such condition to Borrower and the other
     Lenders. After the giving of any such notice and until Agent shall
     otherwise notify Borrower that the circumstances giving rise to such
     condition no longer exist, Borrower's right to request the making of,
     conversion to or a new Interest Period for LIBOR Loans or LIBOR Portions
     shall be suspended. Any LIBOR Loans or LIBOR Portions outstanding at the
     commencement of any such suspension shall be converted at the end of the
     then current Interest Period for such LIBOR Loans or LIBOR Portions into
     Base Rate Loans or Base Rate Portions, as the case may be, unless such
     suspension has then ended.

            (b)   Illegality. If, after the date of this Agreement, the adoption
                  ----------
     of any Governmental Rule, any change in any Governmental Rule or the
     application or requirements thereof (whether such change occurs in
     accordance with the terms of such Governmental Rule as enacted, as a result
     of amendment or otherwise), any change in the interpretation or
     administration of any Governmental Rule by any Governmental Authority, or
     compliance by any Lender with any request or directive (whether or not
     having the force of law) of any Governmental Authority (a "Change of Law")
                                                                -------------
     shall make it unlawful or impossible for any Lender to make or maintain any
     LIBOR Loan or LIBOR Portion, such Lender shall immediately notify Agent and
     Borrower of such Change of Law. Upon receipt of such notice, (i) Borrower's
     right to request the making of, conversion to or a new Interest Period for
     LIBOR Loans or LIBOR Portions shall be terminated, and (ii) Borrower shall,
     at the request of such Lender, either (A) repay any such then outstanding
     LIBOR Loans or LIBOR Portions at the end of the current Interest Period for
     such LIBOR Loans or LIBOR Portions or (B) immediately repay any such LIBOR
     Loans or LIBOR Portions if such Lender shall notify Borrower that such
     Lender may not lawfully continue to fund and maintain such LIBOR Loans or
     LIBOR Portions. Any prepayment of LIBOR Loans or LIBOR Portions made
     pursuant to the preceding sentence prior to the last day of an Interest
     Period for such LIBOR Loans or LIBOR Portions shall be deemed a prepayment
     thereof for purposes of Paragraph 2.12. After any Lender notifies Agent and
                             --------------
     Borrower of such a Change of Law and until such Lender notifies Agent and
     Borrower that it is no longer unlawful or impossible for such Lender to
     make or maintain a LIBOR Loan or LIBOR Portion, all Revolving Loans and all
     Portions of the Term Loan of such Lender shall be Base Rate Loans and Base
     Rate Portions, respectively.

            (c)   Increased Costs. If, after the date of this Agreement, any
                  ---------------
     Change of Law:

                  (i)    Shall subject any Lender to any tax, duty or other
            charge with respect to any LIBOR Loan or LIBOR Portion, or shall
            change the basis of taxation of payments by Borrower to any Lender
            on such a LIBOR Loan or LIBOR Portion or in respect to such a LIBOR
            Loan or LIBOR Portion under

                                       34
<PAGE>

            this Agreement (except for changes in the rate of taxation on the
            overall net income of any Lender imposed by its jurisdiction of
            incorporation or the jurisdiction in which its principal executive
            office is located); or

                  (ii)   Shall impose, modify or hold applicable any reserve
            (excluding any Reserve Requirement or other reserve to the extent
            included in the calculation of the LIBO Rate for any Loans or
            Portions), special deposit or similar requirement against assets
            held by, deposits or other liabilities in or for the account of,
            advances or loans by, or any other acquisition of funds by any
            Lender for any LIBOR Loan or LIBOR Portion; or

                  (iii)  Shall impose on any Lender any other condition related
            to any LIBOR Loan or LIBOR Portion or such Lender's Commitment;

     And the effect of any of the foregoing is to increase the cost to such
     Lender of making, renewing, or maintaining any such LIBOR Loan or LIBOR
     Portion or its Commitment or to reduce any amount receivable by such Lender
     hereunder; then Borrower shall from time to time, within five (5) Business
     Days after demand by such Lender, pay to such Lender additional amounts
     sufficient to reimburse such Lender for such increased costs or to
     compensate such Lender for such reduced amounts. A certificate as to the
     amount of such increased costs or reduced amounts, submitted by such Lender
     to Borrower shall, in the absence of manifest error, be conclusive and
     binding on Borrower for all purposes. The obligations of Borrower under
     this Subparagraph 2.10(c) shall survive the payment and performance of the
          --------------------
     Obligations and the termination of this Agreement.

            (d)   Capital Requirements. If, after the date of this Agreement,
                  --------------------
     any Lender determines that (i) any Change of Law affects the amount of
     capital required or expected to be maintained by such Lender or any Person
     controlling such Lender (a "Capital Adequacy Requirement") and (ii) the
                                 ----------------------------
     amount of capital maintained by such Lender or such Person which is
     attributable to or based upon the Loans, the Commitments or this Agreement
     must be increased as a result of such Capital Adequacy Requirement (taking
     into account such Lender's or such Person's policies with respect to
     capital adequacy), Borrower shall pay to such Lender or such Person, within
     five (5) Business Days after demand by such Lender, such amounts as such
     Lender or such Person shall determine are necessary to compensate such
     Lender or such Person for the increased costs to such Lender or such Person
     of such increased capital. A certificate of any Lender setting forth in
     reasonable detail the computation of any such increased costs, delivered by
     such Lender to Borrower shall, in the absence of manifest error, be
     conclusive and binding on Borrower for all purposes. The obligations of
     Borrower under this Subparagraph 2.10(d) shall survive the payment and
                         --------------------
     performance of the Obligations and the termination of this Agreement

            (e)   Mitigation. Any Lender which becomes aware of (i) any Change
                  ----------
     of Law which will make it unlawful or impossible for such Lender to make or
     maintain any LIBOR Loan or LIBOR Portion or (ii) any Change of Law or other
     event or condition

                                       35
<PAGE>

     which will obligate Borrower to pay any amount pursuant to Subparagraph
                                                                ------------
     2.10(c) or Subparagraph 2.10(d) shall notify Borrower and Agent thereof as
     -------    --------------------
     promptly as practical. If any Lender has given notice of any such Change of
     Law or other event or condition and thereafter becomes aware that such
     Change of Law or other event or condition has ceased to exist, such Lender
     shall notify Borrower and Agent thereof as promptly as practical. Each
     Lender affected by any Change of Law which makes it unlawful or impossible
     for such Lender to make or maintain any LIBOR Loan or LIBOR Portion or to
     which Borrower is obligated to pay any amount pursuant to Subparagraph
                                                               ------------
     2.10(c) or Subparagraph 2.10(d) shall use reasonable commercial efforts
     -------    --------------------
     (including changing the jurisdiction of its Applicable Lending Office) to
     avoid the effect of such Change of Law or to avoid or materially reduce any
     amounts which Borrower is obligated to pay pursuant to Subparagraph 2.10(c)
                                                            --------------------
     or Subparagraph 2.10(d) if, in the
        --------------------
     reasonable opinion of such Lender, such efforts would not be
     disadvantageous to such Lender or contrary to such Lender's normal banking
     practices.

     2.11.  Taxes on Payments.
            -----------------

            (a)   Payments Free of Taxes. All payments made by Borrower under
                  ----------------------
     this Agreement and the other Credit Documents shall be made free and clear
     of, and without deduction or withholding for or on account of, any present
     or future income, stamp or other taxes, levies, imposts, duties, charges,
     fees, deductions or withholdings, now or hereafter imposed, levied,
     collected, withheld or assessed by any Governmental Authority (except net
     income taxes and franchise taxes in lieu of net income taxes imposed on
     Agent or any Lender by its jurisdiction of incorporation or the
     jurisdiction in which its Applicable Lending Office is located) (all such
     non-excluded taxes, levies, imposts, duties, charges, fees, deductions and
     withholdings being hereinafter called "Taxes"). Subject to Subparagraphs
                                                                -------------
     2.11(c) and 2.11(d), if any Taxes are required to be withheld from any
     -------------------
     amounts payable to Agent or any Lender hereunder or under the other Credit
     Documents, the amounts so payable to Agent or such Lender shall be
     increased to the extent necessary to yield to Agent or such Lender (after
     payment of all Taxes) interest or any such other amounts payable hereunder
     at the rates or in the amounts specified in this Agreement and the other
     Credit Documents. Whenever any Taxes are payable by Borrower, as promptly
     as possible thereafter, Borrower shall send to Agent for its own account or
     for the account of such Lender, as the case may be, a certified copy of an
     original official receipt received by Borrower showing payment thereof. If
     Borrower fails to pay any Taxes when due to the appropriate taxing
     authority or fails to remit to Agent the required receipts or other
     required documentary evidence, Borrower shall indemnify Agent and the
     Lenders for any incremental taxes, interest or penalties that may become
     payable by Agent or any Lender as a result of any such failure. The
     obligations of Borrower under this Subparagraph 2.11(a) shall survive the
                                        --------------------
     payment and performance of the Obligations and the termination of this
     Agreement.

            (b)   Withholding Exemption Certificates, Etc. If Agent or any
                  ---------------------------------------
     Lender is not organized under the laws of the United States of America or a
     state thereof, such Person agrees as set forth below in this Subparagraph
                                                                  ------------
     2.11(b).

                  (i)    If any such Person is a "bank" within the meaning of
            Section 881(c)(3)(A) of the IRC, it shall, no later than the Closing
            Date (or, in the case of a Lender which becomes a Lender hereunder
            pursuant to Subparagraph 8.05(c) after the Closing Date, the date
                        --------------------
            upon which such Lender so becomes a Lender hereunder) deliver to
            Borrower and Agent two (2) accurate and complete signed originals of
            IRS Form 4224 or any successor thereto ("Form 4224"), or two
            accurate and complete signed originals of IRS Form 1001 or any
            successor thereto ("Form 1001"), as appropriate, in each case
            indicating that such Person is, on the date of delivery thereof,
            entitled to receive payments of principal, interest and fees under
            this Agreement free from withholding of United States Federal income
            tax. If at any time such Person makes any changes necessitating a
            new Form 4224 or Form 1001, it shall, within thirty (30) days after
            such change becomes effective, deliver to Borrower and Agent in
            replacement for, or in addition to, the forms previously delivered
            by it hereunder, two accurate and complete signed originals of Form
            4224, or two accurate and complete signed originals of Form 1001, as
            appropriate, in each case indicating that such Person is, on the
            date of delivery thereof, entitled to receive payments of principal,
            interest and fees under this Agreement free from withholding of
            United States Federal income tax.

                  (ii)   If any such Person is not a "bank" within the meaning
            of Section 881(c)(3)(A) of the IRC, it shall, no later than the

            hereunder pursuant to Subparagraph 8.05(c) after the Closing Date,
                                  --------------------
            the date upon which such Lender so becomes a Lender hereunder)
            deliver to Borrower and Agent two (2) accurate and complete signed
            originals of IRS Form W-8 or any successor thereto ("Form W-8")
            certifying to such Person's legal entitlement (assuming compliance
            by Borrower with the terms of this Agreement) to an exemption
            whereby such Person is on the date of delivery thereof entitled to
            receive payments of principal, interest and fees under this
            Agreement free from withholding of United States Federal income tax.
            If at any time any such Person makes any changes necessitating a new
            Form W-8, it shall, within thirty (30) days after such change
            becomes effective, deliver to Borrower and Agent in replacement for,
            or in addition to, the forms previously delivered by it hereunder,
            two accurate and complete signed originals of Form W-8 certifying to
            such Person's legal entitlement (assuming compliance by Borrower
            with the terms of this Agreement) to an exemption whereby such
            Person is on the date of delivery thereof entitled to receive
            payments of principal, interest and fees under this Agreement free
            from withholding of United States Federal income tax.

                  (iii)  Each such Person shall, before or within thirty (30)
            days after the occurrence of any event (including the passing of
            time but excluding any event mentioned in clause (i) or (ii) above)
            requiring a change in or renewal of the most recent Form 4224, Form
            1001 or Form W-8 previously delivered by such Person, deliver to
            Borrower and Agent two accurate and complete original signed copies

                                       37
<PAGE>

            of Form 4224, Form 1001 or Form W-8 in replacement for the forms
            previously delivered by such Person.

                  (iv)   Each such Person shall, promptly upon the reasonable
            request of Agent, deliver to Agent such other forms or similar
            documentation as may be required from time to time by any applicable
            Governmental Rule in order to establish such Lender's tax status for
            withholding purposes.

            (c)   Non-Compliance, Etc. Borrower will not be required to pay any
                  -------------------
     additional amounts in respect of United States Federal income tax pursuant
     to Subparagraph 2.11(a) to Agent or any Lender subject to Subparagraph
        --------------------                                   ------------
     2.11(b) if:
     -------

                  (i)    The obligation to pay such additional amounts would not
            have arisen but for a failure by such Person to comply with its
            obligations under Subparagraph 2.11(b); or
                              --------------------

                  (ii)   Such Person is not entitled to exemption from deduction
            or withholding of United States Federal income tax for payments by
            Borrower to such Person hereunder for the account of its Applicable
            Lending Office for any reason other than a Change of Law after the
            date of delivery by such Person of Form 4224, Form 1001 or Form W-8,
            as the case may be.

            (d)   Mitigation. If Agent or any Lender claims any additional
                  ----------
     amounts to be payable to it pursuant to this Paragraph 2.11, such Person
                                                  --------------
     shall use reasonable commercial efforts to file any certificate or document
     requested in writing by Borrower (including without limitation copies of
     Internal Revenue Service Form 1001 (or successor forms) reflecting a
     reduced rate of withholding) or to change the jurisdiction of its
     Applicable Lending Office if the making of such a filing or such change in
     the jurisdiction of its Applicable Lending Office would avoid the need for
     or materially reduce the amount of any such additional amounts which may
     thereafter accrue and if, in the reasonable opinion of such Person, in the
     case of a change in the jurisdiction of its Applicable Lending Office, such
     change would not be disadvantageous to such Person or contrary to such
     Person's normal banking practices.

            (e)   Tax Returns. Nothing contained in this Paragraph 2.11 shall
                  -----------                            --------------
     require Agent or any Lender to make available any of its tax returns (or
     any other information relating to its taxes which it deems to be
     confidential).

     2.12.  Funding Loss Indemnification. If Borrower shall (a) repay, prepay or
            ----------------------------
convert any LIBOR Loan or LIBOR Portion on any day other than the last day of an
Interest Period therefor (whether a scheduled payment, an optional prepayment or
conversion, a mandatory prepayment or a payment upon acceleration or otherwise);
(b) fail to borrow any LIBOR Loan or LIBOR Portion for which a Notice of
Borrowing has been delivered to Agent (whether as a result of the failure to
satisfy any applicable conditions or otherwise); or (c) fail to convert any
Revolving Loans into LIBOR Loans or any Portion of the Term Loan

                                       38
<PAGE>

Borrowing into a LIBOR Portion in accordance with a Notice of Conversion
delivered to Agent (whether as a result of the failure to satisfy any applicable
conditions or otherwise), Borrower shall, upon demand by any Lender, reimburse
such Lender for and hold such Lender harmless from all costs and losses incurred
by such Lender as a result of such repayment, prepayment, conversion or failure.
Borrower understands that such costs and losses may include losses incurred by a
Lender as a result of funding and other contracts entered into by such Lender to
fund a LIBOR Loan or LIBOR Portion. Each Lender demanding payment under this
Paragraph 2.12 shall deliver to Borrower, with a copy to Agent, a certificate
--------------
setting forth the amount of costs and losses for which demand is made, which
certificate shall set forth in reasonable detail the calculation of the amount
demanded. Such a certificate so delivered to Borrower shall constitute prima
facie evidence of such costs and losses. The obligations of Borrower under this
Paragraph 2.12 shall survive the payment and performance of the Obligations and
--------------
the termination of this Agreement.

     2.13.  Replacement of Lenders. If any Lender shall (a) become a Defaulting
            ----------------------
Lender, (b) suspend its obligation to make or maintain LIBOR Loans or LIBOR
Portions pursuant to Subparagraph 2.10(b) for a reason which is not applicable
                     --------------------
to any other Lender or (c) demand any payment under Subparagraph 2.10(c),
                                                    --------------------
2.10(d) or 2.11(a) for a reason which is not applicable to any other Lender,
------------------
then Agent may (or shall, upon the written request of Borrower if no Event of
Default has occurred and is continuing) replace such Lender (the "affected
Lender"), or cause such affected Lender to be replaced, with another lender (the
"replacement Lender") satisfying the requirements of an Assignee Lender under
Subparagraph 8.05(c), by having the affected Lender sell and assign all of its
--------------------
rights and obligations under this Agreement and the other Credit Documents to
the replacement Lender pursuant to Subparagraph 8.05(c); provided, however, that
                                   --------------------  --------  -------
if Borrower seeks to exercise such right, it must give Agent written notice of
its intent to do so within thirty (30) days after it first knows or should have
known of the occurrence of the event or events giving rise to such right and
must effect such replacement within sixty (60) days of giving such notice.
Neither Agent nor any Lender shall have any obligation to identify or locate a
replacement Lender for Borrower. Upon receipt by any affected Lender of a
written notice from Agent stating that Agent is exercising the replacement right
set forth in this Paragraph 2.13, such affected Lender shall sell and assign all
                  --------------
of its rights and obligations under this Agreement and the other Credit
Documents to the replacement Lender pursuant to an Assignment Agreement and
Subparagraph 8.05(c) for a purchase price equal to the sum of the principal
--------------------
amount of the affected Lender's Loans so sold and assigned, all accrued and
unpaid interest thereon and its ratable share of all fees to which it is
entitled.

     Subsidiaries is in violation of or in default with respect to (i) any
     Requirement of Law applicable to such Person; (ii) any Contractual
     Obligation of such Person (nor is there any waiver in effect which, if not
     in effect, would result in such a violation or default), where, in each
     case, such violation or default is reasonably likely to have a Material
     Adverse Effect.  Without limiting the generality of the foregoing, except
     as set forth in the Disclosure Letter, neither Borrower nor any of its
     Subsidiaries (A) has violated any Environmental Laws, (B) has any liability
     under any Environmental Laws or (C) has received notice or other
     communication of an investigation or is under investigation by any
     Governmental Authority having authority to enforce Environmental Laws,
     where such violation, liability or investigation is reasonably likely to
     have a Material Adverse Effect.  No Default has occurred and is continuing.

          (g)  Litigation.  Except as set forth in the Disclosure Letter, no
               ----------
     actions (including, without limitation, derivative actions), suits,
     proceedings or investigations are pending or, to the knowledge of Borrower,
     threatened against Borrower or any of its Subsidiaries at law or in equity
     in any court or before any other Governmental Authority which (i) is
     reasonably likely (alone or in the aggregate) to have a Material Adverse
     Effect or (ii) seeks to enjoin, either directly or indirectly, the
     execution, delivery or performance by Borrower of the Credit Documents or
     the transactions contemplated thereby.

          (h)  Title, Possession under Leases.  Borrower and its Subsidiaries
               ------------------------------
     own and have good and marketable title, or a valid leasehold interest in,
     all their respective properties and assets as reflected in the most recent
     Financial Statements delivered to Agent (except those assets and properties
     disposed of in the ordinary course of business or otherwise in compliance
     with this Agreement since the date of such Financial Statements) and all
     respective assets and properties acquired by Borrower and its Subsidiaries
     since such date (except those disposed of in the ordinary course of
     business or otherwise in compliance with this Agreement). Such assets and
     properties are subject to no Lien, except for Permitted Liens. Each of
     Borrower and its Subsidiaries has complied with all material obligations
     under all material leases to which it is a party and all such leases are in
     full force and effect. Each of Borrower and its Subsidiaries enjoys
     peaceful and undisturbed possession under such leases, except where any
     failure to enjoy such possession (alone or in the aggregate with other such
     failures) is not reasonably likely to have a Material Adverse Effect.

          (i)  Financial Statements.  The Financial Statements of Borrower and
               --------------------
     its Subsidiaries which have been delivered to Agent, (i) are in accordance
     with the books and

                                       42
<PAGE>

     records of Borrower and its Subsidiaries, which have been maintained in
     accordance with good business practice; (ii) have been prepared in
     conformity with GAAP; and (iii) fairly present the financial conditions and
     results of operations of Borrower and its Subsidiaries as of the date
     thereof and for the period covered thereby. As of the date of, and except
     as disclosed in the audited Financial Statements dated December 31, 1998
     furnished by Borrower to Agent prior to the date hereof and in the
     Financial Statements delivered to Agent pursuant to clause (i) or (ii) of
                                                         ---------------------
     Subparagraph 5.01(a), neither Borrower nor any of its Subsidiaries has any
     --------------------
     Contingent Obligations, liability for taxes or other outstanding
     obligations which are material in the aggregate.

          (j)  No Agreements to Sell Assets.  Neither Borrower nor any of its
               ----------------------------
     Subsidiaries has any legal obligation, absolute or contingent, to any
     Person to sell the assets of Borrower or any of its Subsidiaries (other
     than sales in the ordinary course of business), or to effect any merger,
     consolidation or other reorganization of Borrower or any of its
     Subsidiaries or to enter into any agreement with respect thereto.

          (k)  Employee Benefit Plans.
               ----------------------

               (i)   Based on the latest valuation of each Employee Benefit Plan
          that either Borrower or any ERISA Affiliate maintains or contributes
          to, or has any obligation under (which valuation occurred within
          twelve months of the date of this representation), the aggregate
          benefit liabilities of such plan within the meaning of (S) 4001 of
          ERISA did not exceed the aggregate value of the assets of such plan.
          Neither Borrower nor any ERISA Affiliate has any liability with
          respect to any post-retirement benefit under any Employee Benefit Plan
          which is a welfare plan (as defined in section 3(1) of ERISA), other
          than liability for health plan continuation coverage described in Part
          6 of Title I(B) of ERISA, which liability for health plan contribution
          coverage is not reasonably likely to have a Material Adverse Effect.

               (ii)  Each Employee Benefit Plan complies, in both form and
          operation, in all material respects, with its terms, ERISA and the
          IRC, and no condition exists or event has occurred with respect to any
          such plan which, individually or in the aggregate, is reasonably
          likely to have a Material Adverse Effect.  Each Employee Benefit Plan,
          related trust agreement, arrangement and commitment of Borrower or any
          ERISA Affiliate is legally valid and binding and in full force and
          effect.  No Employee Benefit Plan is being audited or investigated by
          any government agency or is subject to any pending or threatened claim
          or suit (other than routine benefits claims).  Neither Borrower nor
          any ERISA Affiliate nor any fiduciary of any Employee Benefit Plan has
          engaged in a prohibited transaction under section 406 of ERISA or
          section 4975 of the IRC which, individually or in the aggregate, is
          reasonably likely to have a Material Adverse Effect.

               (iii)  Neither Borrower nor any ERISA Affiliate contributes to or
          has any material contingent obligations to any Multiemployer Plan.
          Neither Borrower

                                       43
<PAGE>

          nor any ERISA Affiliate has incurred any material liability (including
          secondary liability) to any Multiemployer Plan as a result of a
          complete or partial withdrawal from such Multiemployer Plan under
          Section 4201 of ERISA or as a result of a sale of assets described in
          Section 4204 of ERISA. Neither Borrower nor any ERISA Affiliate has
          been notified that any Multiemployer Plan is in reorganization or
          insolvent under and within the meaning of Section 4241 or Section 4245
          of ERISA or that any Multiemployer Plan intends to terminate or has
          been terminated under Section 4041A of ERISA.

          (l) Other Regulations.  Borrower is not subject to regulation under
              -----------------
     the Investment Company Act of 1940, the Public Utility Holding Company Act
     of 1935, the Federal Power Act, any state public utilities code or to any
     other Governmental Rule limiting its ability to incur indebtedness.

          (m) Patent and Other Rights.  Except as set forth in the Disclosure
              -----------------------
     Letter, Borrower and its Subsidiaries own or license under validly existing
     agreements, and have the full right to license without the consent of any
     other Person, all patents, licenses, trademarks, trade names, trade
     secrets, service marks, copyrights and all rights with respect thereto,
     which are required to conduct their businesses as now conducted, except
     where any failure so to own, license or have the right to license without
     consent (alone or in the aggregate with other such failures) is not
     reasonably likely to have a Material Adverse Effect.

          (n) Governmental Charges.  Borrower and its Subsidiaries have filed or
              --------------------
     caused to be filed all tax returns which are required to be filed by them.
     Borrower and its Subsidiaries have paid, or made provision for the payment
     of, all taxes and other Governmental Charges which have or may have become
     due pursuant to said returns or otherwise and all other indebtedness,
     except such Governmental Charges or indebtedness, if any, which are being
     contested in good faith and as to which adequate reserves (determined in
     accordance with GAAP) have been provided or which are not reasonably likely
     to have a Material Adverse Effect if unpaid.

          (o) Margin Stock.  Borrower owns no Margin Stock which, in the
              ------------
     aggregate, would constitute a substantial part of the assets of Borrower,
     and no proceeds of any Loan will be used to purchase or carry, directly or
     indirectly, any Margin Stock or to extend credit, directly or indirectly,
     to any Person for the purpose of purchasing or carrying any Margin Stock.

          (p) Subsidiaries, etc.  Set forth in Schedule 4.01(p) (as supplemented
              -----------------                ----------------
     by Borrower from time to time in a written notice to Agent) is a complete
     list of all of Borrower's Subsidiaries, the jurisdiction of incorporation
     of each, the classes of Equity Securities of each and the percentages of
     shares of each such class owned directly or indirectly by Borrower.  Except
     for such Subsidiaries, Borrower has no other Subsidiaries, is not a partner
     in any partnership or a joint venturer in any joint venture.

                                       44
<PAGE>

          (q) Solvency, Etc.  Borrower is Solvent and, after the execution and
              -------------
     delivery of the Credit Documents and the consummation of the transactions
     contemplated thereby, will be Solvent.

          (r) Catastrophic Events.  Neither Borrower nor any of its Subsidiaries
              -------------------
     and none of their respective properties is affected by any fire, explosion,
     accident, strike, lockout or other labor dispute, drought, storm, hail,
     earthquake, embargo, act of God or other casualty that is reasonably likely
     to have a Material Adverse Effect.  There are no disputes presently subject
     to grievance procedure, arbitration or litigation under any of the
     collective bargaining agreements, employment contracts or employee welfare
     or incentive plans to which Borrower or any of its Subsidiaries is a party,
     and there are no strikes, lockouts, work stoppages or slowdowns, or, to the
     best knowledge of Borrower, jurisdictional disputes or organizing
     activities occurring or threatened which alone or in the aggregate are
     reasonably likely to have a Material Adverse Effect.

          (s) No Material Adverse Effect.  No event has occurred and no
              --------------------------
     condition exists which is reasonably likely to have a Material Adverse
     Effect.

          (t) Accuracy of Information Furnished.  None of the Credit Documents
              ---------------------------------
     and none of the other certificates, statements or information furnished to
     Agent or any Lender by or on behalf of Borrower or any of its Subsidiaries
     in connection with the Credit Documents or the transactions contemplated
     thereby contains or will contain any untrue statement of a material fact or
     omits or will omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading.

     4.02.     Reaffirmation.  Borrower shall be deemed to have reaffirmed, for
               -------------
the benefit of the Lenders and Agent, each representation and warranty contained
in Paragraph 4.01 on and as of the date of each Credit Event (except for
representations and warranties expressly made as of a specified date, which
shall be true as of such date).

SECTION V.     COVENANTS.

SECTION VII.   THE AGENT AND RELATIONS AMONG LENDERS.
               -------------------------------------

     7.01.     Appointment, Powers and Immunities.  Each Lender hereby appoints
               ----------------------------------
and authorizes Agent to act as its agent hereunder and under the other Credit
Documents with such powers as are expressly delegated to Agent by the terms of
this Agreement and the other Credit Documents, together with such other powers
as are reasonably incidental thereto.  Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in any
other Credit Document, be a trustee for any Lender or have any fiduciary duty to
any Lender.  Notwithstanding anything to the contrary contained herein Agent
shall not be required to take any action which is contrary to this Agreement or
any other Credit Document or any applicable Governmental Rule.  Neither Agent
nor any Lender shall be responsible to any other Lender for any recitals,
statements, representations or warranties made by Borrower or any of its
Subsidiaries contained in this Agreement or in any other Credit Document, for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Credit Document or for any failure by Borrower or
any of its Subsidiaries to perform their respective obligations hereunder or
thereunder.  Agent may employ agents and attorneys-in-fact and shall not be
responsible to any Lender for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.  Neither Agent nor any of
its directors, officers, employees, agents or advisors shall be responsible to
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Credit Document or in connection herewith or therewith,
except for its or their own gross negligence or willful misconduct.  Except

                                       59
<PAGE>

as otherwise provided under this Agreement, Agent shall take such action with
respect to the Credit Documents as shall be directed by the Required Lenders.

     7.02.     Reliance by Agent.  Agent shall be entitled to rely upon any
               -----------------
certificate, notice or other document (including any cable, telegram, facsimile
or telex) believed by it in good faith to be genuine and correct and to have
been signed or sent by or on behalf of the proper Person or Persons, and upon
advice and statements of legal counsel, independent accountants and other
experts selected by Agent with reasonable care.  As to any other matters not
expressly provided for by this Agreement, Agent shall not be required to take
any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Lenders and shall in all
cases be fully protected by the Lenders in acting, or in refraining from acting,
hereunder or under any other Credit Document in accordance with the instructions
of the Required Lenders, and such instructions of the Required Lenders and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders.

     7.03.     Defaults.  Agent shall not be deemed to have knowledge or notice
               --------
of the occurrence of any Default unless Agent has received a written notice from
a Lender or Borrower, referring to this Agreement, describing such Default and
stating that such notice is a "Notice of Default". If Agent receives such a
notice of the occurrence of a Default, Agent shall give prompt notice thereof to
the Lenders. Agent shall take such action with respect to such Default as shall
be reasonably directed by the Required Lenders; provided, however, that until
                                                --------  -------
Agent shall have received such directions, Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable in the best interest of the Lenders.

     7.04.     Indemnification.  Without limiting the Obligations of Borrower
               ---------------
hereunder, each Lender agrees to indemnify Agent, ratably in accordance with
their Proportionate Shares, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may at any time be imposed on, incurred
by or asserted against Agent in any way relating to or arising out of this
Agreement or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or the enforcement of any of the
terms hereof or thereof; provided, however, that no Lender shall be liable for
                         --------  -------
any of the foregoing to the extent they arise from Agent's gross negligence or
willful misconduct.  Agent shall be fully justified in refusing to take or in
continuing to take any action hereunder unless it shall first be indemnified to
its satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The obligations of each Lender under this Paragraph 7.04 shall survive the
                                          --------------
payment and performance of the Obligations, the termination of this Agreement
and any Lender ceasing to be a party to this Agreement (with respect to events
which occurred prior to the time such Lender ceased to be a Lender hereunder).

     7.05.     Non-Reliance.  Each Lender represents that it has, independently
               ------------
and without reliance on Agent, or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own appraisal of the
business, prospects, management, financial condition and affairs of Borrower and
the Subsidiaries and its own decision to enter into this Agreement and agrees
that it will, independently and without reliance upon Agent or any

                                       60
<PAGE>

other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own appraisals and decisions in
taking or not taking action under this Agreement. Neither Agent nor any of its
affiliates nor any of their respective directors, officers, employees, agents or
advisors shall (a) be required to keep any Lender informed as to the performance
or observance by Borrower or any of its Subsidiaries of the obligations under
this Agreement or any other document referred to or provided for herein or to
make inquiry of, or to inspect the properties or books of Borrower or any of its
Subsidiaries; (b) have any duty or responsibility to provide any Lender with any
credit or other information concerning Borrower or any of its Subsidiaries which
may come into the possession of Agent, except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
Agent hereunder; or (c) be responsible to any Lender for (i) any recital,
statement, representation or warranty made by Borrower or any officer, employee
or agent of Borrower in this Agreement or in any of the other Credit Documents,
(ii) the value, validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any Credit Document, (iii) the value or
sufficiency of any collateral or the validity or perfection of any of the liens
or security interests intended to be created by the Credit Documents, or (iv)
any failure by Borrower to perform its obligations under this Agreement or any
other Credit Document.

     7.06.     Resignation or Removal of Agent.  Agent may resign at any time by
               -------------------------------
giving thirty (30) days prior written notice thereof to Borrower and the
Lenders, and Agent may be removed at any time with or without cause by the
Required Lenders.  Upon any such resignation or removal, the Required Lenders
shall have the right to appoint a successor Agent, which Agent, if not a Lender,
shall be reasonably acceptable to Borrower; provided, however, that Borrower
                                            --------  -------
shall have no right to approve a successor Agent if a Default has occurred and
is continuing.  Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from the duties and obligations
thereafter arising hereunder.  After any retiring Agent's resignation or removal
hereunder as Agent, the provisions of this Section VII shall continue in effect
                                           -----------
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as Agent.

     7.07.     Authorization.  Agent is hereby authorized by the Lenders to
               -------------
execute, deliver and perform, each of the Credit Documents to which Agent is or
is intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

     7.08.     Agent in its Individual Capacity.  Agent and its affiliates may
               --------------------------------
make loans to, accept deposits from and generally engage in any kind of banking
or other business with Borrower and its Subsidiaries and affiliates as though
Agent were not Agent hereunder.  With respect to Loans, if any, made by Agent in
its capacity as a Lender, Agent in its capacity as a Lender shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" or "Lenders" shall include Agent in its capacity as a Lender.

     8.02.     Expenses.  Borrower shall pay on demand, whether or not any Loan
               --------
is made hereunder, (a) all reasonable out-of-

                                       63
<PAGE>

pocket fees and expenses, including reasonable out-of-pocket attorneys' fees and
expenses, incurred by Agent in connection with the preparation, negotiation,
execution and delivery of, and the exercise of its duties under, this Agreement
and the other Credit Documents, and the preparation, negotiation, execution and
delivery of amendments and waivers hereunder and thereunder and (b) all
reasonable out-of-pocket fees and expenses, including reasonable out-of-pocket
attorneys' fees and expenses, incurred by Agent and the Lenders in the
enforcement or attempted enforcement of any of the Obligations or in preserving
any of Agent's or the Lenders' rights and remedies (including, without
limitation, all such fees and expenses incurred in connection with any "workout"
or restructuring affecting the Credit Documents or the Obligations or any
bankruptcy or similar proceeding involving Borrower or any of its Subsidiaries).
The obligations of Borrower under this Paragraph 8.02 shall survive the payment
                                       --------------
and performance of the Obligations and the termination of this Agreement.

     8.03.     Indemnification.  To the fullest extent permitted by law,
               ---------------
Borrower agrees to protect, indemnify, defend and hold harmless Agent, the
Lenders and their Affiliates and their respective directors, officers,
employees, agents and advisors ("Indemnitee") from and against any and all
                                 ----------
liabilities, losses, damages or expenses of any kind or nature and from any
suits, claims or demands (including in respect of or for reasonable attorney's
fees and other expenses) arising on account of or in connection with any matter
or thing or action or failure to act by Indemnitee, or any of them, arising out
of or relating to the Credit Documents or any transaction contemplated thereby,
including without limitation any use by Borrower of any proceeds of the Loans,
except to the extent such liability arises from the willful misconduct or gross
negligence of such Indemnitee.  Upon receiving knowledge of any suit, claim or
demand asserted by a third party that Agent or any Lender believes is covered by
this indemnity, Agent or such Lender shall give Borrower notice of the matter
and an opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel satisfactory to Agent or such Lender, as the case may be.  Agent or such
Lender may also require Borrower to defend the matter.  Any failure or delay of
Agent or any Lender to notify Borrower of any such suit, claim or demand shall
not relieve Borrower of its obligations under this Paragraph 8.03 but shall
                                                   --------------
reduce such obligations to the extent of any increase in those obligations
caused solely by any such failure or delay which is unreasonable.  The
obligations of Borrower under this Paragraph 8.03 shall survive the payment and
                                   --------------
performance of the Obligations and the termination of this Agreement.

     8.04.     Waivers; Amendments.  Any term, covenant, agreement or condition
               -------------------
of this Agreement or any other Credit Document may be amended or waived, and any
consent under this Agreement or any other Credit Document may be given, if such
amendment, waiver or consent is in writing and is signed by Borrower and the
Required Lenders (or Agent on behalf of the Required Lenders with the written
approval of the Required Lenders); provided, however that:
                                   --------  -------

          (a) Any amendment, waiver or consent which would (i) increase the
     Total Commitment, (ii) extend the Revolving Loan Maturity Date (other than
     as provided in Subparagraph 2.01(h)) or the Term Loan Maturity Date, (iii)
     reduce the principal of or interest on any Loan or any fees or other
     amounts payable for the account of the Lenders hereunder, (iv) extend any
     scheduled principal, interest or fee payment date, (v)

                                       64
<PAGE>

     amend this Paragraph 8.04, or (vi) amend the definition of Required
                --------------
     Lenders, must be in writing and signed or approved in writing by all
     Lenders;

          (b) Any amendment, waiver or consent which increases or decreases the
     Proportionate Share of any Lender must be in writing and signed by such
     Lender; and

          (c) Any amendment, waiver or consent which affects the rights or
     obligations of Agent must be in writing and signed by Agent.

No failure or delay by Agent or any Lender in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or of
any other right hereunder or thereunder nor shall any single or partial exercise
of any such right preclude any other further exercise thereof or of any other
right hereunder or thereunder.  Unless otherwise specified in such waiver or
consent, a waiver or consent given hereunder shall be effective only in the
specific instance and for the specific purpose for which given.

     8.05.     Successors and Assigns.
               ----------------------

          (a) Binding Effect.  This Agreement and the other Credit Documents
              --------------
     shall be binding upon and inure to the benefit of Borrower, the Lenders,
     Agent, all future holders of the Notes and their respective successors and
     permitted assigns, except that Borrower may not assign or transfer any of
     its rights or obligations under any Credit Document without the prior
     written consent of Agent and each Lender.  All references in this Agreement
     to any Person shall be deemed to include all successors and assigns of such
     Person.

          (b) Participations.  Any Lender may at any time sell to one or more
              --------------
     banks or other financial institutions ("Participants") participating
                                             ------------
     interests in any Loan owing to such Lender, any Note held by such Lender,
     any Commitment of such Lender or any other interest of such Lender under
     this Agreement and the other Credit Documents.  In the event of any such
     sale by a Lender of participating interests, such Lender's obligations
     under this Agreement shall remain unchanged, such Lender shall remain
     solely responsible for the performance thereof, such Lender shall remain
     the holder of its Notes for all purposes under this Agreement and Borrower
     and Agent shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Agreement.
     Any agreement pursuant to which any such sale is effected may require the
     selling Lender to obtain the consent of the Participant in order for such
     Lender to agree in writing to any amendment, waiver or consent of a type
     specified in clause (i), (ii), (iii) or (iv) of Subparagraph 8.04(a) but
                  -------------------------------------------------------
     may not otherwise require the selling Lender to obtain the consent of such
     Participant to any other amendment, waiver or consent hereunder.  Borrower
     agrees that if amounts outstanding under this Agreement and the other
     Credit Documents are not paid when due (whether upon acceleration or
     otherwise), each Participant shall, to the fullest extent permitted by law,
     be deemed to have the right of setoff in respect of its participating
     interest in amounts owing under this Agreement and any other Credit
     Documents to the same extent

                                       65
<PAGE>

     as if the amount of its participating interest were owing directly to it as
     a Lender under this Agreement or any other Credit Documents; provided,
                                                                  --------
     however, that (i) no Participant shall exercise any rights under this
     -------
     sentence without the consent of Agent, (ii) no Participant shall have any
     rights under this sentence which are greater than those of the selling
     Lender and (iii) such rights of setoff shall be subject to the obligation
     of such Participant to share the payment so obtained with all of the
     Lenders as provided in Subparagraph 2.09(b). Borrower also agrees that any
                            --------------------
     Lender which has transferred any participating interest in its Commitment
     or Loans shall, notwithstanding any such transfer, be entitled to the full
     benefits accorded such Lender under Paragraph 2.10, Paragraph 2.11, and
                                         -----------------------------------
     Paragraph 2.12, as if such Lender had not made such transfer.
     --------------

          (c) Assignments.  Any Lender may, at any time, sell and assign to any
              -----------
     Lender or any Eligible Assignee (individually, an "Assignee Lender") all or
                                                        ---------------
     a portion of its rights and obligations under this Agreement and the other
     Credit Documents (such a sale and assignment to be referred to herein as an
     "Assignment") pursuant to an assignment agreement in the form of Exhibit E
      ----------                                                      ---------
     (an "Assignment Agreement"), executed by each Assignee Lender and such
          --------------------
     assignor Lender (an "Assignor Lender") and delivered to Agent for its
                          ---------------
     acceptance and recording in the Register; provided, however, that:
                                               --------  -------

          (i)   Without the written consent of Agent and, if no Default has
     occurred and is continuing, Borrower (which consent of Agent and Borrower
     shall not be unreasonably withheld), no Lender may make any Assignment to
     any Assignee Lender which is not, immediately prior to such Assignment, a
     Lender hereunder or an Affiliate thereof; or

          (ii)  Without the written consent of Agent and, if no Default has
     occurred and is continuing, Borrower (which consent of Agent and Borrower
     shall not be unreasonably withheld), no Lender may make any Assignment to
     any Assignee Lender if, after giving effect to such Assignment, the
     Commitment of such Lender or such Assignee Lender would be less than Ten
     Million Dollars ($10,000,000) (except that a Lender may make an Assignment
     which reduces its Commitment to zero without the written consent of
     Borrower and Agent); or

          (iii) Without the written consent of Agent and, if no Default has
     occurred and is continuing, Borrower (which consent of Agent and Borrower
     shall not be unreasonably withheld), no Lender may make any Assignment
     which does not assign and delegate an equal pro rata interest in such
     Lender's Revolving Loans, Term Loan, Commitment and all other rights,
     duties and obligations of such Lender under this Agreement and the other
     Credit Documents.

     Upon such execution, delivery, acceptance and recording of each Assignment
     Agreement, from and after the Assignment Effective Date determined pursuant
     to such Assignment Agreement, (A) each  Assignee Lender thereunder shall be
     a Lender hereunder with a Proportionate Share as set forth on Attachment 1
                                                                   ------------
     to such Assignment Agreement (under
     ----------------------------

                                       66
<PAGE>

     the caption "Proportionate Share After Assignment") and shall have the
     rights, duties and obligations of such a Lender under this Agreement and
     the other Credit Documents, and (B) the Assignor Lender thereunder shall be
     a Lender with a Proportionate Share as set forth on Attachment 1 to such
                                                         --------------------
     Assignment Agreement (under the caption "Proportionate Share After
     --------------------
     Assignment"), or, if the Proportionate Share of the Assignor Lender has
     been reduced to 0%, the Assignor Lender shall cease to be a Lender and to
     have any obligation to make any Loan; provided, however, that any such
                                           --------  -------
     Assignor Lender which ceases to be a Lender shall continue to be entitled
     to the benefits of any provision of this Agreement which by its terms
     survives the termination of this Agreement. Each Assignment Agreement shall
     be deemed to amend Schedule I to the extent, and only to the extent,
                        ----------
     necessary to reflect the addition of each Assignee Lender, the deletion of
     each Assignor Lender which reduces its Proportionate Share to 0% and the
     resulting adjustment of Proportionate Shares arising from the purchase by
     each Assignee Lender of all or a portion of the rights and obligations of
     an Assignor Lender under this Agreement and the other Credit Documents. On
     or prior to the Assignment Effective Date determined pursuant to each
     Assignment Agreement, Borrower, at its own expense, shall execute and
     deliver to Agent, in exchange for the surrendered Revolving Loan Note or
     Term Loan Note of the Assignor Lender thereunder, a new Revolving Loan Note
     or Term Loan Note to the order of each Assignee Lender thereunder (with
     each new Revolving Loan Note or Term Loan Note to be in an amount equal to
     the Commitment assumed by such Assignee Lender) and, if the Assignor Lender
     is continuing as a Lender hereunder, a new Revolving Loan Note or Term Loan
     Note to the order of the Assignor Lender (with the new Revolving Loan Note
     or Term Loan Note to be in an amount equal to the Commitment retained by
     it). Each such new Revolving Loan Note or Term Loan Note shall be dated the
     Closing Date or the date of the Term Loan Borrowing (as applicable), and
     each such new Note shall otherwise be in the form of the Note replaced
     thereby. The Notes surrendered by the Assignor Lender shall be returned by
     Agent to Borrower marked "replaced". Each Assignee Lender which was not
     previously a Lender hereunder and which is not incorporated under the laws
     of the United States of America or a state thereof shall, within three (3)
     Business Days of becoming a Lender, deliver to Borrower and Agent two duly
     completed copies of United States Internal Revenue Service Form 1001 or
     4224 (or successor applicable form), as the case may be, certifying in each
     case that such Lender is entitled to receive payments under this Agreement
     without deduction or withholding of any United States federal income taxes.

          (d) Register.  Agent shall maintain at its address referred to in
              --------
     Paragraph 8.01 a copy of each Assignment Agreement delivered to it and a
     --------------
     register (the "Register") for the recordation of the names and addresses of
                    --------
     the Lenders and the Proportionate Shares of each Lender from time to time.
     The entries in the Register shall be conclusive in the absence of manifest
     error, and Borrower, Agent and the Lenders may treat each Person whose name
     is recorded in the Register as the owner of the Loans recorded therein for
     all proposes of this Agreement.  The Register shall be available for
     inspection by Borrower or any Lender at any reasonable time and from time
     to time upon reasonable prior notice.

                                       67
<PAGE>

          (e) Registration.  Upon its receipt of an Assignment Agreement
              ------------
     executed by an Assignor Lender and an Assignee Lender (and, to the extent
     required by Subparagraph 8.05(c), by Borrower and Agent) together with
                 --------------------
     payment to Agent by Assignor Lender of a registration and processing fee of
     $4,000, Agent shall (i) promptly accept such Assignment Agreement and (ii)
     on the "Assignment Effective Date" determined pursuant thereto record the
     information contained therein in the Register and give notice of such
     acceptance and recordation to the Lenders and Borrower.  Agent may, from
     time to time at its election, prepare and deliver to the Lenders and
     Borrower a revised Schedule I
                        ----------
     reflecting the names, addresses and respective Proportionate Shares of all
     Lenders then parties hereto.

          (f)  Confidentiality.  Agent and the Lenders may disclose the Credit
               ---------------
     Documents and any financial or other information relating to Borrower or
     any Subsidiary to each other or to any potential Participant or Assignee
     Lender that has executed a confidentiality letter in the form of Exhibit F.
                                                                      ---------

     8.06.     Setoff; Security Interest.
               -------------------------

          (a)  Setoff.  In addition to any rights and remedies of the Lenders
               ------
     provided by law, each Lender shall have the right, with the prior consent
     of Agent but without prior notice to or consent of Borrower, any such
     notice and consent being expressly waived by Borrower to the extent
     permitted by applicable law, upon the occurrence and during the continuance
     of an Event of Default, to setoff and apply against the Obligations any
     amount owing from such Lender to Borrower.  The aforesaid right of set-off
     may be exercised by such Lender against Borrower or against any trustee in
     bankruptcy, debtor in possession, assignee for the benefit of creditors,
     receiver or execution, judgment or attachment creditor of Borrower or
     against anyone else claiming through or against Borrower or such trustee in
     bankruptcy, debtor in possession, assignee for the benefit of creditors,
     receiver, or execution, judgment or attachment creditor, notwithstanding
     the fact that such right of set-off may not have been exercised by such
     Lender at any prior time.  Each Lender agrees promptly to notify Borrower
     after any such set-off and application made by such Lender, provided that
                                                                 --------
     the failure to give such notice shall not affect the validity of such set-
     off and application.

          (b)  Security Interest.  As security for the Obligations, Borrower
               -----------------
     hereby grants to Agent and each Lender, for the benefit of all Lenders, a
     continuing security interest in any and all deposit accounts or moneys of
     Borrower now or hereafter maintained with such Lender.  Each Lender shall
     have all of the rights of a secured party with respect to such security
     interest.

     8.07.     No Third Party Rights.  Nothing expressed in or to be implied
               ---------------------
from this Agreement is intended to give, or shall be construed to give, any
Person, other than the parties hereto and their permitted successors and assigns
hereunder, any benefit or legal or equitable right, remedy or claim under or by
virtue of this Agreement or under or by virtue of any provision herein.

                                       68
<PAGE>

     8.08.     Partial Invalidity.  If at any time any provision of this
               ------------------
Agreement is or becomes illegal, invalid or unenforceable in any respect under
the law or any jurisdiction, neither the legality, validity or enforceability of
the remaining provisions of this Agreement nor the legality, validity or
enforceability of such provision under the law of any other jurisdiction shall
in any way be affected or impaired thereby.

     8.09.     Jury Trial.  EACH OF BORROWER, THE LENDERS AND AGENT, TO THE
               ----------
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT
TO TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT.

     8.10.     Counterparts.  This Agreement may be executed in any number of
               ------------
identical counterparts, any set of which signed by all the parties hereto shall
be deemed to constitute a complete, executed original for all proposes.

     8.11.     Confidentiality.  Each Lender shall, at or prior to the time it
               ---------------
becomes a party to this Agreement, execute and deliver to Agent and Borrower a
confidentiality letter in the form of Exhibit F.  Any disclosure made by any
                                      ---------
Lender in violation of any such confidentiality letter may entitle Borrower to
damages or injunctive relief but shall not affect the obligations of Borrower
and its Subsidiaries under this Agreement and the other Credit Documents.

                      [The first signature page follows.]

payment is made, with weights proportional to the present value of the payment.

A maturity, by definition, shall include puts, announced calls, auctions, or

at a quantifiable price prior to the stated final maturity consistent with
preservation of capital and liquidity requirements.

Marketability
-------------

All holdings in the portfolio, except for those instruments which can be
classified as cash and cash equivalent, should be of sufficient size and in
issues that are actively trades to minimize transaction costs and to facilitate
accurate market valuation. When the total portfolio falls below $25 million the
above diversification limits may be exceeded upon approval by the Chief
Financial Officer in order to avoid having several small investments that are
not really marketable or that have yields below market rates.

Credit Downgrade
----------------

The Chief Financial Officer shall be notified immediately if any investment that
met the criteria of this policy at the time of purchase is subsequently
downgraded by Standard & Poor's, Moody's or an equivalent rating agency. After

functional currencies of the Company and its subsidiaries.  No security
purchased can have currency exposure.

provide required liquidity.

context of maximizing after-tax return, but this is not the primary goal or
function of the policy.

be solicited for every security offered for sale.

All purchases and sales will be done in the name of the Company with the
approved brokers, dealers, and banks.

No. 115, "Accounting for Certain Investments in Debt and Equity Securities."

                              [Lender letterhead]

                                     [Date]

Acuson Corporation
1220 Charleston Road
Mountain View, CA  94043
Attn:  Treasurer

     Re:  Credit Agreement dated as of April 9, 1999 (the "Credit Agreement")
          among Acuson Corporation ("Borrower"), the financial institutions
          parties thereto (the "Lenders") and ABN AMRO Bank N.V., as agent for
          the Lenders ("Agent") - Confidentiality Agreement

Ladies and Gentlemen:

     In order to permit ____________________ ("Lender") to evaluate the business
                                               ------
and financial prospects and condition of Borrower in connection with Lender's
[proposed] participation as a [Lender][participant] in the Credit Agreement,
Borrower, Agent or another Lender may have made or may hereafter make available
to Lender certain confidential financial information and other non-public
information relating to Borrower (the "Confidential Information").  This letter
                                       ------------------------
agreement sets out the understandings between Lender and Borrower with respect
Lender's treatment and control of the Confidential Information.

     Lender will use the Confidential Information solely in connection with the
Credit Agreement, including Lender's determination of whether to become a [party
to][participant under] the Credit Agreement.  Lender will endeavor in good faith
to maintain the confidentiality of the Confidential Information and, except as
provided below, will exercise reasonable efforts to prevent the disclosure of
the Confidential Information to third parties or to Lender's officers, employees
and agents except those officers, employees and agents who need to know in
connection with the purpose set forth in the first sentence of this paragraph.
If Lender elects not to participate in the Credit Agreement, Lender will
promptly return or destroy all Confidential Information (including any copies,
extracts, or summaries) if requested to do so by Borrower at any time after
discussions have been terminated and before Lender has become obligated to
participate in the Credit Agreement, provided that Lender may retain such
Confidential Information (subject to the obligations contained herein) as it
deems necessary in order to comply with ordinary and customary retention
requirements of financial institutions, sound banking practices and audit and
examination requirements.

     Notwithstanding anything in this letter agreement to the contrary,
Confidential Information shall not include information that either (a) is in the
public domain or the knowledge or possession of Lender on a non-confidential
basis when disclosed to Lender or becomes part of

                                      G-1
<PAGE>

the public domain after disclosure to Lender through no fault of Lender, or (b)
is disclosed to Lender by a third party, provided Lender does not have actual
knowledge that such third party is prohibited from disclosing such information.

     The terms of this letter agreement shall not apply to disclosure of
Confidential Information that is, in the good faith opinion of Lender, compelled
by laws, regulations, rules, orders, or legal process or proceedings, provided
that Lender uses reasonable efforts to give Borrower sufficient notice to permit
Borrower to seek an order restraining such disclosure, or is disclosed to (a)
any party, including a prospective assignee or participant, that has signed a
confidentiality agreement containing terms substantially similar to those
contained herein, (b) legal counsel, examiners, auditors, and directors of
Lender and examiners, auditors, and investigators having regulatory authority
over Lender, or (c) any party in connection with the excise of remedies by
Lender (or Agent on behalf of Lenders) after the occurrence of any "Event of
Default" as defined in the Credit Agreement.

     It is agreed that money damages would not be a sufficient remedy for breach
of this letter agreement by Lender and that Borrower shall be entitled to
specific performance or other equitable relief as a remedy for any such breach.
Such remedy shall not be deemed to be the exclusive remedy for Lender's breach
of this letter agreement but shall be in addition to all other remedies
available at law or equity to Borrower.  Lender agrees that the provisions of
this letter agreement shall be deemed to apply, with equal force and effect, to
any of Lender's representatives, affiliates, or associates and that Lender shall
be responsible for any breach of the provisions of this letter agreement by any
of its directors, officers, employees, affiliates, or associates.

     This letter agreement shall be governed by and be construed in accordance
with the laws of the State of California (excluding the choice of law rules
thereof) and is binding upon the successors and assigns of Lender and Borrower.
This letter agreement supersedes any prior agreements between Borrower and
Lender regarding confidential information furnished to Lender in connection with
the Credit Agreement.

                                               Very truly yours,
