     equal to the product of (i) the average, computed for the period referred
     to in clause (iii) below, of the Federal Funds Rate for each day included
     in such period, times (ii) the amount to have been paid by such Lender on
     such purchase date, times (iii) a fraction, the numerator of which is the
     number of days that elapse from and including the date scheduled for such
     purchase to the date on which the amount of such Lender's Commitment
     Percentage of such unpaid Swing Line Advance shall become immediately
     available to the Agent, and the denominator of which is 365. A statement of
     the Agent submitted to such Lender with respect to any amounts owing under
     this paragraph shall be prima facie evidence of the amount due and owing to
     Fleet by such Lender, absent manifest error. When such Lender shall pay
     such amount to the Agent for the account of Fleet, such amount so paid in
     respect of principal shall constitute a Revolving Credit Loan which is a
     Base Rate Loan made by such Lender on such date for purposes of this
     Agreement.

2.6  Letters of Credit.

(a)  The Borrower may use the Revolving Credit Commitment for Letters of Credit
     to be issued by the Issuing Bank, provided that in each case (a) the
     Borrower executes and delivers a letter of credit application and
     reimbursement agreement reasonably satisfactory to the Issuing Bank and
     complies with any conditions to the issuance of such Letter of Credit
     (including payment of any applicable fees); (b) the Issuing Bank has
     approved the form of such Letter of Credit; (c) the requested Letter of
     Credit is for a purpose permitted by Section 8.1 hereof; (d) such Letter of
     Credit bears an expiration date not later than one year from its date of
     issuance and not later than the Maturity Date; (e) the conditions set forth
     in Section 6.1 shall have been satisfied as of the date of the issuance of
     the Letter of Credit; and (f) both before the issuance of the requested
     Letter of Credit and after giving effect to the issuance thereof the sum of
     (i) all outstanding Revolving Credit Loans, Swing Line Advances and Letter
     of Credit Usage shall not exceed the Revolving Credit Commitment; and (ii)
     the Letter of Credit Usage shall not exceed $3,000,000.

(b)  Effective upon the issuance of each Letter of Credit and without any
     further action on the part of the Issuing Bank or the Lenders in respect
     thereof, the Issuing Bank hereby grants to each Lender, and each Lender
     hereby acquires from the Issuing Bank, a participating interest in such
     Letter of Credit to the extent of such Lender's Commitment Percentage
     thereof and each Lender severally agrees that it shall be absolutely
     liable, without regard to the occurrence of any Default or Event of
     Default, to the extent of such Lender's Commitment Percentage thereof, to
     reimburse the Issuing Bank on demand for the amount of each draft paid by
     the Issuing Bank under each Letter of Credit to the extent that such amount
     is not reimbursed by the Borrower.  Each Lender's obligation to make
     further Loans to the Borrower shall be reduced by such Lender's Percentage
     of Letter of Credit Usage.

(c)  In order to induce the Issuing Bank to issue, extend and renew each Letter
     of Credit, the Borrower hereby agrees to reimburse or pay to the Issuing
     Bank, for the account of the Issuing Bank or (as the case may be) the
     Lenders, with respect to each Letter of Credit issued, extended or renewed
     by the Issuing Bank hereunder, on each date that any draft presented under
     any Letter of Credit is honored by the Issuing Bank or the Issuing Bank
     otherwise makes payment with respect thereto, (i) the amount paid by the
     Issuing Bank under or with respect to

                                     -16-
<PAGE>

     such Letter of Credit, and (ii) the amount of any reasonable and customary
     fees, charges or other costs and expenses whatsoever incurred by the
     Issuing Bank or any Lender in connection with any payment made by the
     Issuing Bank under, or with respect to, such Letter of Credit.

(d)  If any draft shall be presented or other demand for payment shall be made
     under any Letter of Credit, the Issuing Bank shall notify the Borrower of
     the date and amount of the draft presented or demand for payment and of the
     date and time when it expects to pay such draft or honor such demand for
     payment. On the date that such draft is paid or other payment is made by
     the Issuing Bank, the Issuing Bank shall promptly notify the Lenders of the
     amount of any unpaid Reimbursement Obligation.  All such unpaid
     Reimbursement Obligations with respect to Letters of Credit shall be deemed
     to be Base Rate Loans.  No later than 12:00 noon (Boston time) on the
     Banking Day next following the receipt of such notice, each Lender shall
     make available to the Agent, at the Agent's head office, in immediately
     available funds, such Lender's Commitment Percentage of such unpaid
     Reimbursement Obligation, together with an amount equal to the product of
     (i) the average,  computed for the period referred to in clause (iii)
     below, of the weighted average interest rate paid by the Agent for federal
     funds acquired by the Agent during each day included in such period, times
     (ii) the amount equal to such Lender's Commitment Percentage of such unpaid
     Reimbursement Obligation, times (iii) a fraction, the numerator of which is
     the number of days that have elapsed from and including the date the
     Issuing Bank paid the draft presented for honor or otherwise made payment
     until the date on which such Lender's Commitment Percentage of such unpaid
     Reimbursement Obligation shall become immediately available to the Agent,
     and the denominator of which is 365.  The responsibility of the Issuing
     Bank to the Borrower shall be only to determine that the documents
     (including each draft) delivered under each Letter of Credit in connection
     with such presentment shall be in conformity in all material respects with
     such Letter of Credit.

(e)  The Borrower's Reimbursement Obligations shall be absolute and
     unconditional under any and all circumstances and irrespective of the
     occurrence of any Default or Event of Default or any condition precedent
     whatsoever or any set off, counterclaim or defense to payment which the
     Borrower may have or have had against the Issuing Bank, the Agent, the
     Lenders or any beneficiary of a Letter of Credit.  The Borrower further
     agrees that the Issuing Bank, the Agent and the Lenders shall not be
     responsible for, and the Borrower's Reimbursement Obligations shall not be
     affected by, among other things, the validity or genuineness of documents
     or of any endorsements thereon, even if such documents should in fact prove
     to be in any or all respects invalid, fraudulent or forged, or any dispute
     between or among the Borrower, the beneficiary of any Letter of Credit or
     any financing institution or other party to which any Letter of Credit may
     be transferred or any claims or defenses whatsoever of the Borrower,
     against the beneficiary of any Letter of Credit or any such transferee.

(f)  The Issuing Bank, the Agent and the Lenders shall not be liable for any
     error, omission, interruption or delay in transmission, dispatch or
     delivery of any message or advice, however transmitted, in connection with
     any Letter of Credit.  The Borrower agrees that any action taken or omitted
     by the Issuing Bank, the Agent or the Lenders under or in connection with
     each Letter of Credit and the related drafts and documents, if done in good
     faith, shall be binding upon the Borrower and shall not result in any
     liability on the part of the Issuing Bank, the Agent or the Lenders to the
     Borrower except, in the case of any such party, any such liability resulted
     from the gross negligence or willful misconduct of such party.

                                     -17-
<PAGE>

2.7  Maturity of Loans.  All Loans shall mature and the total unpaid principal
amount thereunder shall be due and payable on the Maturity Date, or such earlier
date on which the Loans and all other sums owing under this Agreement and the
other Loan Documents shall be due as a result of acceleration, at which time all
amounts advanced under this Section 2 shall be immediately due and payable.

2.8  Termination or Reduction of Commitment.

(a)  The Revolving Credit Commitment shall automatically terminate at 5:00 p.m.
     Boston time on the Maturity Date.  The Borrower, upon notice to the Agent
     and each Lender in accordance with Section 4.4 and the repayment in full of
     the outstanding principal balance of the Loans (and accrued interest
     thereon) and the payment in full of any expenses or other fees owed by the
     Borrower to the Agent or any Lender under or pursuant to this Agreement,
     may elect to terminate the Revolving Credit Commitment permanently,
     whereupon the Commitments of the Lenders shall be terminated entirely.  If
     any Letters of Credit would remain outstanding after the effective date of
     any such termination, in addition to the satisfaction of all other
     applicable terms and conditions of this Agreement, the Borrower shall
     either deposit with and pledge to the Agent cash in an amount equal to 100%
     of the Letter of Credit Usage at the effective date of such termination, or
     (ii) arrange for the termination of such Letters of Credit and the return
     thereof to the Issuing Bank. No such termination may be reinstated.

(b)  The Borrower may also, upon notice to the Agent and each Lender in
     accordance with Section 4.4, reduce the Revolving Credit Commitment in
     integral multiples of $500,000, whereupon the Commitments of the Lenders
     shall be reduced pro rata in accordance with their respective Commitment
     Percentages by the aggregate amount specified in such notice.  If, as a
     result of any such reduction, the aggregate outstanding balance of
     Revolving Credit Loans, Swing Line Advances plus the Letter of Credit Usage
     would exceed the Revolving Credit Commitment, the Borrower shall, as a
     condition precedent to any such reduction, deposit with and pledge to the
     Agent cash in an amount equal to 100% of such excess or to make repayments
     of outstanding Revolving Credit Loans and/or Swing Line Advances in an
     aggregate amount equal to such excess.  No such reduction may be
     reinstated.

2.9  Several Obligations.  The failure of any Lender to make any Loan to be made
by it on the date specified therefor shall not relieve any other Lender of its
obligation to make its Loan on such date, but neither the Agent nor any Lender
shall be responsible for the failure of any other Lender to make a Loan to be
made by such other Lender.

Section 3.  [Intentionally Omitted]

Section 4.  Interest Rates; Fees; Payments.

4.1  Interest Rates.

(a)  The Borrower agrees to pay to the Agent for the account of each Lender
     interest on the unpaid principal amount of each Loan for each day from and
     including the date such Loan is made to but excluding the date the
     principal of such Loan is paid in full at the following rates per annum:

                                     -18-
<PAGE>

     (i)  for Loans which are Base Rate Loans, at a rate per annum equal to the
          Alternate Base Rate plus the Applicable Margin; and

     (ii) for Loans which are LIBOR Loans, at a rate per annum equal to the
          LIBOR Rate plus the Applicable Margin.

(b)  Notwithstanding the foregoing, if an Event of Default shall occur, then at
     the option of the Agent or the Majority Lenders, the unpaid balance of
     Loans and any other amount payable hereunder which is not paid in full when
     due shall bear interest at a rate per annum equal to the Post-Default Rate,
     until such Event of Default is cured or waived.

(c)  Accrued interest on each Base Rate Loan shall be payable monthly in arrears
     on the first day of each month, accrued interest on LIBOR Loans shall be
     payable on the last day of each Interest Period and, if any such Interest
     Period is longer than three months, at intervals of three months after the
     first day thereof, and interest on all Loans shall be payable in any event
     upon the payment, prepayment or conversion thereof, but only on the
     principal so paid or prepaid or converted; provided that interest payable
     pursuant to Section 4.1(b) during the pendency of an Event of Default shall
     be payable from time to time on demand of the Agent.  Promptly after the
     determination of any interest rate provided for herein or any change
     therein, the Agent shall notify the Borrower and each of the Lenders
     thereof.

(d)  Notwithstanding the foregoing provisions of this Section 4.1, if at any
     time the rate of interest set forth in subparagraph (a) above (the "Stated
     Rate") exceeds the maximum non-usurious interest rate permissible for any
     Lender to charge a commercial borrower under applicable law (the "Maximum
     Rate"), the rate of interest charged on the Loans by such Lender hereunder
     shall be limited to the Maximum Rate.  As used herein, the term "applicable
     law" shall mean the law in effect as of the date hereof provided, however,
     in the event there is a change which results in a higher permissible rate
     of interest, then the rate of interest provided for herein shall be
     governed by such new law as of its effective date.  In the event the Stated
     Rate that has theretofore been subject to the preceding sentence at any
     time is less than the Maximum Rate in respect of the Loans hereunder by any
     Lender, the principal amount of the Loans shall bear interest at the
     Maximum Rate until the total amount of interest paid to such Lender or
     accrued on such Loans by such Lender hereunder equals the amount of
     interest which would have been paid to the Lenders or accrued on the Loans
     by the Lenders hereunder if the Stated Rate had at all times been in
     effect.  In the event that upon payment in full of all amounts payable
     hereunder, the total amount of interest paid to any Lender or accrued on
     such Lender's Loans under the terms of this Agreement is less than the
     total amount of interest which would have been paid to such Lender or
     accrued on such Lender's Loans if the Stated Rate had at all times been in
     effect, then the Borrower shall, to the extent permitted by applicable law,
     pay to such Lender an amount equal to the difference between (a) the lesser
     of (i) the amount of interest which would have accrued on the Loans if the
     Maximum Rate had at all times been in effect or (ii) the amount of interest
     which would have accrued on the Loans if the Stated Rate had at all times
     been in effect and (b) the amount of interest actually paid to the Lenders
     or accrued on the Loans under this Agreement.  In the event any Lender ever
     receives, collects or applies as interest any sum in excess of the Maximum
     Rate, such excess amount shall be applied to the reduction of the principal
     balance of such Lender's Loans or to other amounts (other than interest)
     payable hereunder, and if no such principal is then outstanding, such
     excess or part thereof remaining shall be paid to the Borrower.

                                     -19-

4.2 Commitment Fee. The Borrower shall pay to the Agent for the ratable account
of each Lender quarterly in arrears on the first day of each quarter a
commitment fee on the actual daily balance of the unutilized portion of the
Commitment for the preceding quarter at a rate per annum as set forth on
Schedule 1 attached hereto based on the actual number of days elapsed in the
period based on a year of 360 days.

4.3 Letter of Credit Fees. In connection with each Letter of Credit, the
Borrower shall pay to the Issuing Bank any applicable issuance, amendment,
transfer and similar fees in accordance with the Issuing Bank's customary
charges and in connection with the issuance or extension of any Standby Letter
of Credit shall also pay an annual standby commission equal to the then
effective Applicable Margin for LIBOR Loans of the total face amount of such
Standby Letter of Credit. In addition, the Borrower shall pay to the Issuing
Bank a fronting fee equal to 0.25% of the total face amount of each Letter of
Credit.

4.4 Certain Notices. Notices to the Agent of borrowings, conversions and
prepayments of Loans, of the duration of Interest Periods and of termination or
reduction of Commitments shall be irrevocable and shall be effective only if
received by the Lenders not later than the time specified below on the number of
Banking Days prior to the date of the borrowing, conversion, prepayment,
termination or reduction specified below:

</TABLE>

Each notice of borrowing, conversion or prepayment shall specify the amount, the
Type of the Loan to be borrowed, converted or prepaid, the date of borrowing,
conversion or prepayment (which shall be a Banking Day in the case of the
prepayment of a Base Rate Loan, or a Working Day in the case of the conversion
or prepayment of a LIBOR Loan) and, in the case of LIBOR Loans, the duration of
the Interest Period therefor (subject to the definition of Interest Period).
Each such notice of duration of an Interest Period shall specify the Loans to
which such Interest Period is to relate, provided, however, as long as an Event
of Default has occurred and is continuing, the Borrower's right to request new
LIBOR Loans shall cease.   In the event that the Borrower fails to select the
duration of any Interest Period for any LIBOR Loan within the time period and
otherwise as provided in this Section 4.4, such LIBOR Loan will be automatically

                                     -20-
<PAGE>

converted into a Base Rate Loan on the last day of the then current Interest
Period for such LIBOR Loan or (if outstanding as Base Rate Loans) will remain
as, or (if not then outstanding) will be made as Base Rate Loans. In the case of
a Swing Line Advance, the notice shall specify the maturity date thereof (which
maturity date shall be a Banking Day no later than fourteen (14) days after the
date such Swing Line Advance is requested to be made and a date prior to the
Maturity Date).

4.5  Non-Receipt of Funds by the Agent. Unless the Agent shall have been
notified by a Lender or the Borrower (the "Payor") prior to the date on which
such Lender is to make payment to the Agent of the proceeds of a Loan to be made
by it hereunder or the Borrower is to make a payment to the Agent for the
account of one or more of the Lenders, as the case may be (such payment being
herein called the "Required Payment"), which notice shall be effective upon
receipt, that the Payor does not intend to make the Required Payment to the
Agent, the Agent may assume that the Required Payment has been made and may, in
reliance upon such assumption (but shall not be required to), make the amount
thereof available to the intended recipient on such date and, if the Payor has
not in fact made the Required Payment to the Agent, the recipient of such
payment shall, on demand, pay to the Agent the amount made available to it
together with interest thereon in respect of the period commencing on the date
such amount was so made available by the Agent until the date the Agent recovers
such amount at a rate per annum equal to the Federal Funds Rate for such period.

4.6  Sharing of Payment; Waiver of Enforcement Without Consent, Etc.

(a)  The Borrower agrees that, in addition to (and without limitation of) any
     right of set-off, banker's lien or counterclaim any Lender may otherwise
     have, each Lender shall be entitled, at its option and without regard to
     the adequacy of any other Collateral or Subsidiary Collateral held by or
     for the benefit of such Lender, to offset balances (whether based on
     provisional or final credits or on collected or uncollected funds),
     credits, securities or other property of the Borrower or any Subsidiary
     held by such Lender, for the account of the Borrower at any of its offices,
     in Dollars or in any other currency (collectively, the "Deposited Funds"),
     against any principal of or interest on any Loans to the Borrower by any
     Lender hereunder, or any other Obligation of the Borrower hereunder, which
     is not paid when due, taking into account any applicable grace period,
     (regardless of whether such balances are then due to the Borrower), in
     which case it shall promptly notify the Borrower, the Agent and the other
     Lenders thereof, provided that such Lender's failure to give such notice
     shall not affect the validity thereof.  The Borrower further grants to the
     Agent for the benefit of the Agent and each Lender a lien, security
     interest and right of set-off in all such Deposited Funds, it being agreed
     that the possession of any such Deposited Funds by any Lender shall be for
     the benefit of the Agent and the Lenders, provided, however, that nothing
     herein shall restrict the Borrower from using such Deposited Funds unless
     and until a Default or Event of Default shall have occurred and be
     continuing.  The Borrower agrees, to the fullest extent it may effectively
     do so under applicable law, that any Person purchasing a participation in
     the Loans made, or other obligations held, by another Person, whether or
     not acquired pursuant to the foregoing arrangements, may exercise all
     rights of set-off, banker's lien, counterclaim or similar rights with
     respect to such participation as fully as if such Lender were a direct
     holder of Loans or other obligations in the amount of such participation.
     ANY AND ALL RIGHTS TO REQUIRE THE AGENT OR A LENDER TO EXERCISE ITS RIGHTS
     OR REMEDIES WITH RESPECT TO ANY OTHER

                                     -21-
<PAGE>

     COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF
     WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER OR
     ANY GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

(b)  The Lenders agree among themselves that no Lender shall, except with the
     written consent of the Majority Lenders, exercise any right pursuant to
     Section 4.6(a) or exercise, with respect to any Loans or other obligations
     hereunder, any other right of set-off, banker's Lien, counterclaim or
     similar right, so long as any Lender has any Commitment hereunder or any
     amounts due hereunder remain unpaid.

(c)  If a Lender shall obtain payment of any principal of or interest on any
     Loan made by it under this Agreement, or on any other obligation then due
     to such Lender hereunder, through the exercise of any right of set-off,
     banker's lien, counterclaim or similar right, or otherwise, it shall
     promptly notify the Agent and purchase from the other Lenders
     participations in the Loans made, or other obligations held, by the other
     Lenders in such amounts, and make such other adjustments from time to time
     as shall be equitable to the end that all the Lenders shall share the
     benefit of such payment (net of any expenses which may be incurred by such
     Lender in obtaining or preserving such benefit) pro rata in accordance with
     the unpaid principal and interest on the Loans or other obligations then
     due to each of them.  To such end, all the Lenders shall make appropriate
     adjustments among themselves (by the resale of participations sold or
     otherwise) if such payment is rescinded or must otherwise be restored
     (including the payment of interest to the extent that the Lender obligated
     to return such funds is obligated to return interest).

(d)  Each Lender waives all rights to enforce, and shall not attempt to enforce,
     any rights hereunder, under the Notes or under any other Loan Document
     without the prior written consent of the Majority Lenders.  Each Lender
     further agrees that all rights under the Security Instruments shall be
     exercised only through the Agent under the Security Instruments.

(e)  Nothing contained herein shall require any Lender to exercise any right of
     set-off, banker's Lien, counterclaim or similar right or shall affect the
     right of any Lender to exercise, and retain the benefits of exercising, any
     such right with respect to any other indebtedness or obligation of any
     Borrower.

(f)  This Section 4.6 is for the benefit of the Lenders only and does not
     constitute a waiver of any rights against the Borrower or any of its
     Subsidiaries or against any property held as security for any obligations
     hereunder or under any Loan Document.

4.7  Minimum and Maximum Amounts.  Each borrowing, conversion and prepayment of
principal of Revolving Credit Loans shall be in an aggregate principal amount
equal to (a) in the case of LIBOR Loans, $500,000 or a larger multiple of
$100,000, and (b) in the case of Base Rate Loans, $250,000 (or, in the case of
Swing Line Advances, $100,000) or a larger multiple of $50,000 (conversions or
prepayments of Revolving Credit Loans of different Types or, in the case of
LIBOR Loans, having different Interest Periods, at the same time hereunder shall
be deemed separate conversions and prepayments for purposes of the foregoing,
one for each Type or Interest Period); provided that any payment or prepayment
in full of the Loans may be in the aggregate outstanding principal amount
thereof.

                                     -22-
<PAGE>

4.8  Computations.  All interest on LIBOR Loans shall be computed on the basis
of a year of 360 days and actual days elapsed (including the first day but
excluding the last day) occurring in the period for which payable and all
interest on Base Rate Loans shall be computed on the basis of a year of 365 days
(or 366 days in the case of a leap year) and actual days elapsed (including the
first but excluding the last day) occurring in the period for which payable.

4.9  Manner and Place of Payment.  All payments under this Agreement shall be
made not later than 1:00 p.m. (Boston Time) on the date when due and shall be
made in lawful money of the United States in immediately available funds at the
Office of the Agent for the account of each Lender or by the Borrower's check
drawn on the depositary account(s) maintained by the Borrower with the Agent
payable to the Agent for the account of each Lender or its order.  All payments
shall be made without setoff, counterclaim, withholding or reduction of any kind
whatsoever.  The Agent (or any Lenders for whose account any such payment is
made) may (but shall not be obligated to) debit the amount of any such payment
on the date when due, taking into account any applicable grace period, to any
ordinary deposit account of the Borrower with the Agent, or such Lender, as the
case may be, without notice to the Borrower.  The Borrower shall, at the time of
making each payment hereunder or under any Note, specify to the Agent the Loans
or other amounts payable by the Borrower hereunder to which such payment is to
be applied (and in the event that they fail to so specify, or if an Event of
Default has occurred and is continuing, the Agent may apply such payment for the
benefit of the Lenders as it may elect in its sole discretion, but subject to
the other terms and conditions of this Agreement, including without limitation,
Section 4.10 hereof).  Each payment received by the Agent hereunder or under any
Note for the account of a Lender shall be paid promptly to such Lender, in
immediately available funds, for the account of such Lender's Applicable Lending
Office.

4.10  Pro Rata Treatment.  Except to the extent otherwise provided herein:  (a)
each borrowing from the Lenders under Section 2.1 hereof shall be made from the
Lenders and the payment of the commitment fee under Section 4.2 hereof shall be
made for the account of the Lenders pro rata according to the Lenders'
Commitment Percentage, (b) each payment by the Borrower of principal of or
interest on Loans of a particular Type shall be made to the Agent for the
account of the Lenders pro rata in accordance with the respective unpaid
principal amounts of such Loans held by the Lenders and (c) each conversion of
Loans of a particular Type shall be made pro rata among the Lenders in
accordance with the respective principal amounts of such Loans held by the
Lenders.

4.11  Payments Due on Days Other than Banking Days.  Subject to the definition
of "Interest Period" with respect to LIBOR Loans as set forth in Section 1.1,
whenever any payment to be made hereunder or under the Notes shall be due on a

Banking Day, and such extension of time shall be included in computing any
interest or fees due.

4.12  Additional Costs.

(a)  The Borrower shall pay to the Agent for the account of each Lender from
     time to time such amounts as such Lender may determine to be necessary to
     compensate it for any costs incurred by such Lender which such Lender
     determines are attributable to its making or maintaining of any LIBOR Loans
     hereunder or its obligation to make any of such Loans hereunder, or any
     reduction in any amount receivable by such Lender hereunder in respect of
     any LIBOR Loan or such obligation (such increases in costs and reductions
     in amounts receivable being herein called "Additional Costs"), in each case
     resulting from any Regulatory Change which:

     (i)  changes the basis of taxation of any amounts payable to such Lender
          under this Agreement or the Notes in respect of any LIBOR Loan; or

     (ii) imposes or modifies any reserve, special deposit or similar
          requirements (other than the Reserve Requirement, to the extent it is
          taken into consideration in determining the LIBOR Rate) relating to
          any extensions of credit or other assets of, or any deposits with or
          other liabilities of, such Lender (including any LIBOR Loan or any
          deposits referred to in the definition of "LIBOR Rate" below).

Each Lender will provide the Borrower notice of any event occurring after the
date of this Agreement which will entitle such Lender to compensation pursuant
to this Section as promptly as practicable after it obtains knowledge thereof
and determines to request such compensation.  Each Lender will furnish the
Borrower with a statement, in reasonable detail, setting forth the basis and
amount of each request by such Lender for compensation under this Section.
Within 30 days of the notice by such Lender, the Borrower shall pay the Agent
for the benefit of the affected Lender that portion of such increased costs
incurred or reduction in an amount received which is attributable to making,
funding and maintaining such affected Lender's Loans hereunder.  If such sum is
not paid within such 30 day period, it shall bear interest at the Post-Default
Rate until paid in full.  The Borrower shall not be required to make any such
payment for such increased costs arising prior to the date which is one hundred
twenty (120) days before the date of such notice (unless and only to the extent
such law, rule, regulation, policy, guideline, directive or interpretation
applies retroactively to a period prior to the date which is one hundred twenty
(120) days before the date of such notice, in which case, the Borrower shall not
be required to make any payment for increased costs resulting from such
retroactive application unless such Lender provides such notice within one
hundred twenty (120) days after such rule, regulation, policy, guideline,
directive or interpretation is published in final form and the Lender reasonably
should have been aware thereof.  If any affected Lender shall subsequently
recoup costs for which such Lender has heretofore been compensated by the
Borrower under this Section 4.12, such Lender shall remit to the Borrower the
amount of such recoupment.

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

                                     -24-
<PAGE>

     (i)  Determinations and allocations by any Lender for purposes of this
          Section of the effect of any Regulatory Change on its costs of
          maintaining its obligations to make LIBOR Loans or of making or
          maintaining LIBOR Loans or on amounts receivable by it in respect of
          LIBOR Loans, and of the additional amounts required to compensate such
          Lender in respect of any Additional Costs, shall be conclusive absent
          manifest error, provided that such determinations and allocations are
          made on a reasonable basis.

4.13  Limitation on Types of Loans.  Anything herein to the contrary
notwithstanding, if, with respect to any LIBOR Loans, the Majority Lenders
determine in good faith (which determination shall be conclusive) that the
relevant rates of interest referred to in the definition of "LIBOR Rate" upon
the basis of which the rates of interest for any LIBOR Loan are to be determined
do not accurately reflect the cost to such Lenders of making or maintaining such
LIBOR Loans for the Interest Period therefor, then the Agent shall promptly
notify the Borrower, and so long as such condition remains in effect, the
Lenders shall be under no obligation to make LIBOR Loans or to convert Base Rate
Loans into LIBOR Loans and the Borrower shall, on the last day(s) of the then
current Interest Period(s) for the outstanding LIBOR Loans, either prepay such
LIBOR Loans or convert such LIBOR Loans into Base Rate Loans.

4.14  Illegality.  Notwithstanding any other provision of this Agreement to the
contrary, in the event that it becomes unlawful for any Lender or its LIBOR
Lending Office to (a) honor its obligation to make LIBOR Loans hereunder, or (b)
maintain LIBOR Loans hereunder, then such Lender shall promptly notify the
Borrower thereof (identifying the illegality in question in reasonable detail)
and such Lenders' obligation to make LIBOR Loans hereunder shall be suspended
until such time as such Lender may again make and maintain LIBOR Loans.

4.15  Substitute Base Rate Loans.  If the obligation of any Lender to make LIBOR
Loans shall be suspended pursuant to Sections 4.12, 4.13 or 4.14 hereof, all
Loans which would otherwise be made by such Lender as LIBOR Loans shall be made
instead as Base Rate Loans (and, if an event referred to in Section 4.12(b) or
Section 4.14 has occurred and such Lender so requests, by notice to the
Borrower, each LIBOR Loan of such Lender then outstanding shall be automatically
converted into a Base Rate Loan on the date specified by such Lender in such
notice) and, to the extent that LIBOR Loans are so made as (or converted into)
Base Rate Loans, all payments of principal which would otherwise be applied to
such LIBOR Loans shall be applied instead to such Base Rate Loans.

4.16  LIBOR Indemnity.  If the Borrower for any reason (including, without
limitation, pursuant to Sections 2.7, 4.14 and 11.2 hereof) makes any payment of
principal with respect to any LIBOR Loan on any day other than the last day of
an Interest Period applicable to such LIBOR Loan, or fails to borrow or continue
or convert to a LIBOR Loan after giving a Notice of Borrowing or Conversion
thereof pursuant to Section 4.4, or fails to prepay a LIBOR Loan after having
given notice thereof, the Borrower shall pay to the Agent for the benefit of the
Lenders any amount required to compensate the Lenders for any additional losses,
costs or expenses which they may reasonably incur as a result of such payment or
failure, including, without limitation, any loss (including loss of anticipated
profits), costs or expense incurred by reason of

                                     -25-
<PAGE>

the liquidation or re-employment of deposits or other funds required by the
Lenders to fund or maintain such LIBOR Loan. Without limiting the foregoing, the
Borrower shall pay to the Agent a "yield maintenance fee" in an amount computed
as follows: the current rate for United States Treasury securities (bills on a
discounted basis shall be converted to a bond equivalent) with a maturity date
closest to the remaining balance of the Interest Period for the Loan with
respect to which the prepayment is made, shall be subtracted from the interest
rate applicable (pursuant to Section 4.1(a)(ii)) to each LIBOR Loan in effect at
the time of prepayment. If the result is zero or a negative number, there shall
be no yield maintenance fee. If the result is a positive number, then the
resulting percentage shall be multiplied by the amount of the principal balance
being prepaid. The resulting amount shall be divided by 360 and multiplied by
the number of days remaining in the Interest Period for the Loan with respect to
which the prepayment is made. Said amount shall be reduced to present value
calculated by using the above referenced United States Treasury securities rate
and the number of days remaining in the Interest Period for the Loan with
respect to which the prepayment is made. The resulting amount shall be the yield
maintenance fee due to the Lenders upon the payment of a LIBOR Loan under the
circumstances described in the first sentence of this Section. The Borrower
shall pay such amount upon presentation by the Agent of a statement setting
forth the amount and the Agent's (or the affected Lenders') calculation thereof
pursuant hereto, which statement shall be deemed true and correct absent
manifest error. If the Obligations are declared immediately due and payable
pursuant to Section 11.2, then any amount provided for in this Section shall be
due and payable in the same manner as though the Borrower had made a prepayment
of the LIBOR Loans.

4.17  Capital Adequacy.  If any Lender shall determine that the applicability of
any law, rule, regulation or guideline adopted pursuant to or arising out of the
July 1988 report of the Basle Committee on Banking Regulations and Supervisory
Practices entitled "International Convergence of Capital Measurement and Capital
Standards", or the adoption after the date hereof of any other applicable law,
rule, regulation or guideline regarding capital adequacy, or any change in the
foregoing or in the enforcement, interpretation or administration thereof by any
Governmental Authority charged with the enforcement, interpretation or
administration thereof, or compliance by such Lender or any Person controlling
such Lender (a "Parent") with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such Governmental
Authority, has or would have the effect of reducing the rate of return on
capital of such Lender or its Parent as a consequence of such Lender's
obligations hereunder to a level below that which such Lender (or its Parent)
could have achieved but for such applicability, adoption, change or compliance
(taking into consideration the policies of such Lender (or its Parent) with
respect to capital adequacy) by an amount reasonably deemed by such Lender to be
material, then such Lender shall provide the Borrower notice thereof.  A
statement of such Lender, in reasonable detail, claiming compensation under this
Section and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive absent manifest error; provided that the
determination thereof is made on a reasonable basis.  In determining such
amount, such Lender may use any reasonable averaging and attribution methods.
Within 30 days of the notification by such Lender, the Borrower shall pay the
Agent for the benefit of the affected Lender that portion of such increased
costs incurred (including any reduction in the rate of return on capital to an
amount below that which such Lender could have achieved but for such change in
regulation after taking into account the Lenders' policies as to capital
adequacy) or reduction in an amount received which is attributable to making,
funding and maintaining such

                                     -26-
<PAGE>

affected Lender's Loans hereunder. If such sum is not paid within such 30 day
period, it shall bear interest at the Post-Default Rate until paid in full. The
Borrower shall not be required to make any such payment for such increased costs
arising prior to the date which is one hundred twenty (120) days before the date
of such notice (unless and only to the extent such law, rule, regulation,
policy, guideline, directive or interpretation applies retroactively to a period
prior to the date which is one hundred twenty (120) days before the date of such
notice, in which case, the Borrower shall not be required to make any payment
for increased costs resulting from such retroactive application unless such
Lender provides such notice within one hundred twenty (120) days after such
rule, regulation, policy, guideline, directive or interpretation is published in
final form and the Lender reasonably should have been aware thereof). If any
affected Lender shall subsequently recoup costs for which such Lender has
heretofore been compensated under this Section 4.17 by the Borrower, such Lender
shall remit to the Borrower the amount of such recoupment.

4.18  Optional Prepayments.  The Borrower shall have the right to prepay the
Loans in whole or in part and to convert Loans of one Type into another Type,
without premium or penalty, at any time and from time to time, provided that (i)
at the time of the prepayment in full of all Extensions of Credit, the Borrower
shall pay all interest accrued on the amount prepaid; (ii) the Borrower shall
give the Agent notice of such prepayment as provided in Section 4.4; (iii) LIBOR
Loans may be converted into Base Rate Loans only on the last day of an Interest
Period thereof; and (iv) the Agent for the account of each Lender shall be paid,
at the time of any prepayment of a LIBOR Loan that is being prepaid on other
than the last day of an Interest Period therefor, the amount provided for in
Section 4.16.

4.19  Mandatory Prepayments.  In the event the Borrower after the date hereof
closes any public offering of its capital stock or makes a disposition of any of
its assets other than to the extent permitted by under clauses (i) and (ii) of
Section 9.3, the Borrower shall be required to prepay the Loans in an amount
equal to the net proceeds (after costs and expenses associated with such
offering or disposition of assets) received by the Borrower in such offering or
disposition of assets.

Section 5.  Security Interests.

(a)  In connection with the Prior Credit Agreement, the Borrower granted to the
     Agent for the benefit of the Lenders a security interest in, and a lien on,
     all right, title and interest of the Borrower in and to substantially all
     the assets of the Borrower (excluding Excluded Property) and by entering
     into a security agreement in favor of the Agent for the benefit of the
     Lenders dated as of December 4, 1998 (the "Security Agreement") in order to
     secure payment and performance of the Borrower's Obligations to the Agent
     and the Lenders under the Prior Credit Agreement and the Notes and the
     other Loan Documents as defined therein.

(b)  In connection with the Prior Credit Agreement, the Borrower caused each of
     its Subsidiaries to grant to the Agent for the benefit of the Lenders
     thereunder a security interest in, and a lien on, all right, title and
     interest of each such Subsidiary in and to substantially all the assets of
     each such Subsidiary (excluding Excluded Property) and by entering into a
     security agreement in favor of the Agent for the benefit of such Lenders
     (collectively, the "Subsidiary Security Agreements") in order to secure
     payment and performance of the Borrower's Obligations to the Agent and the
     Lenders under the Prior Credit Agreement and the Notes and the other Loan
     Documents as defined therein.  A list of the Subsidiary Security Agreements
     that are as of the date hereof in full force and effect is set forth on
     Schedule A.

                                     -27-
<PAGE>

(c)  In connection with the Prior Credit Agreement, the Borrower entered into a
     stock pledge agreement in favor of the Agent for the benefit of the Lenders
     dated as of December 4, 1998 (the "Stock Pledge Agreement") providing for
     the pledge to the Agent for the benefit of the Lenders of all outstanding
     capital stock of all present and future Subsidiaries of the Borrower and
     delivered to the Agent for the benefit of the Lenders certificates
     representing all such shares accompanied by undated stock powers or other
     appropriate instruments of transfer duly executed in blank.  A list of the
     Stock Pledge Agreements that are as of the date hereof in full force and
     effect are set forth on Schedule A.

(d)  The Borrower agrees that all references in the Security Agreement, the
     Subsidiary Security Agreements and the Stock Pledge Agreement, to the Prior
     Credit Agreement and the Notes issued in connection therewith shall mean
     and be a reference to this Agreement and the Notes issued hereunder and
     that the definition of "Secured Obligations" in such Security Instruments
     shall include all Obligations as defined herein.

Section 6.  Conditions Precedent.

6.1  Conditions to all Loans and Letters of Credit.  The Lenders shall not be
obligated to make any of the Loans to the Borrower and the Issuing Bank shall
not be obligated to issue any Letter of Credit hereunder until the following

     In order to induce the Agent and the Lenders to enter into this Agreement
and to make the contemplated Extensions of Credit, the Borrower hereby
represents and warrants as follows to the Agent and the Lenders  (except to the
extent qualified by supplemental disclosure set forth on Schedule A hereto) and
the following representations and warranties (to the extent so qualified, if
any) shall survive the execution and delivery of this Agreement and the Notes:

7.1  Corporate Status.  The Borrower and each Guarantor is a duly organized and
validly existing corporation in good standing under the laws of the state of its
organization and is duly qualified or licensed as a foreign corporation in good
standing in each jurisdiction in which the failure to do so would have a
Material Adverse Effect.

7.2  No Violation.  Neither the execution, delivery or performance of this
Agreement or any other Loan Document, nor consummation of the transactions
contemplated therein or thereby will (i) contravene any law, statute, rule or
regulation to which the Borrower or any Guarantor is subject or any judgment,
decree, franchise, order or permit applicable to the Borrower or any Guarantor
where such contravention has or could reasonably be anticipated to have a
Material Adverse Effect, or (ii) conflict or be inconsistent with or will result
in any breach of, or constitute a default under, or result in or require the
creation or imposition of any Lien (other than the liens created by the Security
Instruments) upon any of the property or assets of the Borrower or any Guarantor
pursuant to, any Contractual Obligation of the Borrower or any Guarantor, or
(iii) violate any provision of the corporate charters or by-laws of the Borrower
or any Guarantor.

                                     -30-
<PAGE>

7.3  Corporate Power and Authority.  The execution, delivery and performance of
this Agreement and the other Loan Documents to which it is a party are within
the corporate powers of the Borrower and each Guarantor and have been duly
authorized by all necessary corporate action.

7.4  Enforceability.  This Agreement and each other Loan Document to which it is
a party constitutes valid and binding obligations of the Borrower and each
Guarantor enforceable against the Borrower and each Guarantor in accordance with
its terms, except as be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors'
rights generally and subject to general principles of equity, whether applied in
a court of equity or at law.

7.5  Consents or Approvals.  No order, permission, consent, approval, license,
authorization, registration or validation of, or filing with, or exemption by,
any Governmental Authority or any other Person is required to authorize, or is
required in connection with, the execution, delivery and performance of this
Agreement or any other Loan Document by the Borrower or any Guarantor, or the
taking of any action contemplated hereby or thereby, except where the failure to
obtain such authorization could reasonably be anticipated to have a Material
Adverse Effect and except for the filing of UCC-1 financing statements in the
appropriate UCC filing offices listed on the Perfection Certificate (as defined
in the Security Agreement) and for routine filings under federal securities
laws.

7.6  Financial Statements.

(a)  The Borrower has furnished the Agent with the consolidated balance sheet of
     the Borrower and its Subsidiaries as of the Financial Statement Date, and
     the related consolidated statements of operations, stockholders' equity and
     cash flows for the year then ended, which have been audited by the
     Accountants.  Such financial statements, including the related schedules
     and notes, fairly present the consolidated financial position of the
     Borrower and its Subsidiaries as of the Financial Statement Date, and the
     results of their operations and their cash flows for the year then ended in
     conformity with GAAP.

(b)  During the period from the Financial Statement Date to the Closing Date:
     (i) except as permitted pursuant to Section 9.3 or identified in Schedule A
     or in the Borrower's Form 10-Q filed with the SEC for the first quarter of
     2000, copies of which have previously been delivered to Agent, there has
     been no sale, transfer or other disposition by the Borrower or any of its
     Subsidiaries of any material part of their business or property and, except
     as set forth in Schedule A, no purchase or other acquisition of any
     business or property (including any capital stock of any Person) material
     in relation to the consolidated financial condition of the Borrower and its
     Subsidiaries at the Financial Statement Date; and (ii) neither the Borrower
     nor any of its Subsidiaries have made a Restricted Payment, or agreed or
     committed to make a Restricted Payment, except as permitted pursuant to

(c)  The Borrower has and, after giving effect to the Loans to be made on the
     Closing Date, will have, assets (both tangible and intangible),  having a
     value in excess of the amount required to pay the probable liability on its
     then-existing debts (whether matured or unmatured, liquidated or
     unliquidated, fixed or contingent); the Borrower has and will have access
     to adequate capital for the conduct of its business and the discharge of
     its debts incurred in connection therewith as such debts mature; the
     Borrower was not insolvent immediately prior to the making of the Loans on
     the Closing Date and immediately after giving effect thereto, the Borrower
     will not be insolvent.

(d)  All the above-referenced financial statements (including the related
     schedules and notes) have been prepared in accordance with GAAP applied
     consistently throughout the periods involved (except as approved by the
     Accountants and disclosed therein and, in the case of interim financial
     statements, subject to normal year-end adjustments and the absence of
     footnotes and schedules).

7.7  No Material Change.  Since the Financial Statement Date there has been no
development or event, or to the best knowledge of the Borrower, any prospective
development or event, which has had or could reasonably be anticipated to have a
Material Adverse Effect.

7.8  Litigation.  There are no actions, suits or proceedings pending or
threatened against or affecting the Borrower or any of its Subsidiaries which
(i) are not set forth on the attached Schedule A or (ii) in any one case or in
the aggregate, if determined adversely to the interests of such party, could
reasonably be anticipated to have a Material Adverse Effect.

7.9  Compliance with Other Instruments; Compliance with Law.  Neither the
Borrower nor any of its Subsidiaries are (after taking into account applicable
cure periods) in default under any Contractual Obligation (including any
Contractual Obligation relating to any Indebtedness of the Borrower) where such
default could reasonably be anticipated to have a Material Adverse Effect.
Neither the Borrower nor any of its Subsidiaries are in default and/or in
violation of any applicable statute, rule, writ, injunction, decree, order or
regulation of any Governmental Authority having jurisdiction over the Borrower
or its Subsidiaries which default or violation (i) is not set forth on the
attached Schedule A or (ii) could reasonably be anticipated to have a Material
Adverse Effect.

7.10  Subsidiaries.  On the Closing Date, the Borrower does not have any
Subsidiaries except as set forth on attached Schedule A.

7.11  Investment Company Status; Limits on Ability to Incur Indebtedness.  The
Borrower is not an "investment company" or a company "controlled by" an
investment company within the meaning of the Investment Company Act of 1940, as
amended.  The Borrower is not subject to regulation under any Federal or State
statute or regulation which limits its ability to incur Indebtedness.

7.12  Title to Property.  The Borrower and each of its Subsidiaries has good and
marketable title to all of its properties and assets, including the properties
and assets reflected in the consolidated balance sheet of the Borrower as of the
Financial Statement Date, except such as have been disposed of since that date
in the ordinary course of business, and none of such

                                     -32-
<PAGE>

properties or assets is subject to any Lien except for (a) Permitted Liens, or
(b) a defect in title or other claim other than defects and claims that, in the
aggregate, would have no Material Adverse Effect. The Borrower and each of its
Subsidiaries enjoys peaceful and undisturbed possession under all leases
necessary in any material respect for the operation of their properties and
assets and no material default exists under such leases (after taking into
account applicable cure periods under said leases). All such leases are valid
and subsisting and are in full force and effect.

7.13  ERISA.  The Borrower and each member of the Funding Standard Controlled
Group have fulfilled their obligations under the minimum funding standards of
ERISA and the Code with respect to pension plans maintained by the Borrower or
any member of the Funding Standard Controlled Group or to which the Borrower or
any member of the Funding Standard Controlled Group is obligated to contribute,
except where the failure to fulfill such obligations would not result in the
aggregate of an "accumulated funding deficiency", within the meaning of Section
302 of ERISA, in excess of $250,000.  The Borrower and each member of the
Controlled Group are in compliance in all material respects with the presently
applicable provisions of ERISA and the Code, and have not incurred any liability
to the PBGC or a Plan under Title IV of ERISA (other than to make contributions
or premium payments in the ordinary course).

7.14  Taxes.  All tax returns of the Borrower and its Subsidiaries required to
be filed have been timely filed (after giving effect to any permitted
extensions) except for any tax returns which if not filed on a timely basis
would not have a Material Adverse Effect, all material taxes, fees and other
governmental charges (other than those being  contested in good faith by
appropriate proceedings diligently conducted and with respect to which adequate
accruals have been established and, in the case of ad valorem taxes or
betterment assessments, no proceedings to foreclose any lien with respect
thereto have been commenced and, in all other cases, no notice of lien has been
filed or other action taken to perfect or enforce such lien) shown thereon which
are payable have been paid.  The charges and reserves on the books of the
Borrower and its Subsidiaries for all income and other taxes are adequate, and
the Borrower knows of no additional assessment or any basis therefor.  The
Federal income tax returns of the Borrower and its Subsidiaries have not been
audited within the last three years, all prior audits have been closed, and
there are no unpaid assessments, penalties or other charges arising from such
prior audits, except as set forth on the attached Schedule A.

7.15  Environmental Matters.

(a)  The Borrower and each of its Subsidiaries have obtained all Governmental
     Approvals that are required for the operation of their business under any
     Environmental Law, except where the failure to so obtain a Governmental
     Approval would not have a Material Adverse Effect.

(b)  The Borrower and each of its Subsidiaries are in compliance with all terms
     and conditions of all required Governmental Approvals and are also in
     compliance with all terms and conditions of all applicable Environmental
     Laws, noncompliance with which would have a Material Adverse Effect.

                                     -33-
<PAGE>

(c)  There is no civil, criminal or administrative action, suit, demand, claim,
     hearing, notice of violation, investigation, proceeding, notice or demand
     letter pending or, to the best knowledge of the Borrower threatened against
     the Borrower or any of its Subsidiaries relating in any way to the
     Environmental Laws which could have a Material Adverse Effect, and there is
     no Lien of any private entity or Governmental Authority against any
     Borrower Group Property, which Lien could have a Material Adverse Effect.

(d)  There has been no claim, complaint, notice, or request for information
     received by the Borrower or any Subsidiary with respect to any site listed
     on the National Priority List promulgated pursuant to the Comprehensive
     Environmental Response, Compensation, and Liability Act ("CERCLA") 42 USC
     (S) 9601 et seq. or any state list of sites requiring investigation or
     cleanup with respect to contamination by Hazardous Substances, which claim,
     complaint, notice, or request for information could have a Material Adverse
     Effect.

(e)  To the best of the Borrower's knowledge, there has been no release or
     threat of release of any Hazardous Substance at any Borrower Group Property
     which would likely result in liability being imposed upon the Borrower or
     any Subsidiary thereof, which liability would have a Material Adverse
     Effect.

7.16  Intellectual Property.  The Borrower and each of its Subsidiaries owns or
licenses such copyrights, patents, trademarks and similar rights ("Intellectual
Property") as are necessary for the conduct of its respective businesses as now
conducted, without any known conflict with the rights of others which would have
a Material Adverse Effect.

7.17  Level of Borrowing.  After giving effect to any Extensions of Credit to be
made as of the date hereof under this Agreement, the sum of all outstanding
Revolving Credit Loans, Swing Line Advances and Letter of Credit Usage do not
exceed the Revolving Credit Commitment.

7.18  Malpractice Insurance.  The senior management of the Borrower, and each of
its Subsidiaries, has concluded, after the exercise of reasonable business
judgment, that such entities are not engaged in the practice of dentistry and
are not required to maintain malpractice insurance and that if such senior
management concludes after the Closing Date that such entities are required to
maintain malpractice insurance, the Borrower covenants and agrees to, and will
require each of its Subsidiaries to, obtain and maintain comprehensive
malpractice insurance against bodily injury and death with financially sound and
reputable insurance companies in such amounts and against such risks as are
usually carried by owners of similar businesses and properties in the same
general areas in which the Borrower and its Subsidiaries operate.

7.19  Management Services Agreements.  The Borrower and its Subsidiaries have
entered into management services agreements (the "Management Services
Agreement") substantially in the form previously delivered to the Agent (with
certain variations to the fee structure and the type of personnel employed by
the Subsidiaries) with the Persons set forth on attached Schedule A.  Subject to
any restrictions under applicable law, all such Management Services Agreements
are freely assignable to third parties and collaterally assignable to the Agent
without the consent of any party to such Management Services Agreements, except
as set forth on Schedule A.

7.20  Disclosure.  None of the representations or warranties made by the
Borrower in this Agreement, or  in any other document furnished to the Agent or
the Lenders by or on behalf of the Borrower in connection herewith contains (or
will contain on the Closing Date) any untrue statement of a material fact or
omits (or will omit on the Closing Date) to state any material fact necessary to
make the statements herein or therein, in light of the circumstances under which
they are made, not misleading.  There is no fact known to the Borrower on the
date of this Agreement which has any reasonable likelihood of having a Material
Adverse Effect which has not been set forth in or referred to in this Agreement.

Section 8.  Affirmative Covenants.

     The Borrower covenants and agrees that for so long as this Agreement is in
effect and until the Notes, together with all interest thereon and all other
Obligations of the Borrower and the Guarantors to the Lenders are paid or
satisfied in full, unless the Majority Lenders shall otherwise consent in
writing:

8.1  Use of Proceeds.  The Borrower shall use the proceeds of Revolving Credit
Loans for the working capital purposes of the Borrower and its Subsidiaries and
for Permitted Acquisitions, including for payments under Letters of Credit and
for the costs and expenses of the transactions contemplated hereby.  Without
limiting the foregoing, no part of such proceeds will be used for the purpose of
purchasing or carrying any "margin security" as such term is defined in
Regulation U of the Board of Governors of the Federal Reserve System.

8.2  Conduct of Business; Maintenance of Existence.  The Borrower will, and will
cause of each of its Subsidiaries to, continue to engage in the business in

corporation, licensed and in good standing in each jurisdiction where such
qualification or licensing is required by the nature of its business, the
character and location of its property, business, or the ownership or leasing of
its property, except where such noncompliance or failure to so qualify would not
have a Material Adverse Effect, and the Borrower will maintain its properties in
good operating condition, and continue to conduct its business as presently
conducted.

8.3  Compliance with Laws.  The Borrower will, and will cause each of its
Subsidiaries to, comply in all material respects with all applicable laws,
ordinances, rules, regulations and requirements of Governmental Authorities.

8.4  Insurance.

     insurance with financially sound and reputable insurance companies in such
     amounts and with such deductibles and against such risks as is usually
     carried by owners of similar businesses and properties in the same general
     areas in which the Borrower and its Subsidiaries operate, provided that in
     any event the Borrower and its Subsidiaries shall maintain or cause to be
     maintained (i) insurance against casualty, loss or damage covering all
     property and improvements of the Borrower and its Subsidiaries in amounts
     and in respect of perils usually carried by owners of similar businesses
     and properties in the same general areas in which Borrower and its

                                     -35-
<PAGE>

     Subsidiaries operate; (ii) comprehensive general liability insurance
     against claims for bodily injury, death or property damage; and (iii)
     workers' compensation insurance to the extent required by applicable law.
     Such policies may be blanket policies covering the Borrower and all its
     Subsidiaries.  In the case of policies referenced in clauses (i) and (ii)
     above, all such insurance shall (x) name the Borrower and the Agent, for
     the benefit of the Lenders, as loss payees for losses exceeding $500,000
     and additional insureds as their interests may appear; (y) provide that no
     termination, cancellation or material reduction in the amount or material
     modification to the extent of coverage shall be effective until at least 30
     days after receipt by the Agent of notice thereof; and (z) be reasonably
     satisfactory in all other respects to the Agent.  Notwithstanding the
     foregoing, the Borrower may upon a determination to such effect by its
     Board of Directors and notice to the Agent, self insure, in whole or in
     part, for risks and claims of the type described in clauses (i) and (ii) of
     the first sentence of this Section 8.4 to the extent that self insurance is
     normal and customary for similarly situated businesses.

(b)  The Borrower will not enter into any management service agreement or
     similar agreement with an affiliated dentist or professional corporation
     unless such dentist or professional corporation agrees to maintain
     comprehensive malpractice insurance against claims for bodily injury and
     death with financially sound and reputable insurance companies in such
     amounts and against such risks as is usually carried by dentists in the
     same general areas in which such dentists operate.

(c)  As long as no Default or Event of Default shall have occurred and be
     continuing, the Agent shall return to the Borrower any insurance proceeds
     it receives in payment of a claim filed by the Borrower or any of its
     Subsidiaries.

           Borrower Group Property, or any part thereof, to contain Hazardous
           Substances in violation of any Environmental Laws, or which does
           cause, or could cause, such Borrower Group Property to be subject to

or on its property, except liabilities being contested in good faith and by
proper proceedings, as to which adequate accruals are maintained on the books of
the Borrower or its Subsidiaries, in accordance with GAAP.

8.9  ERISA Information.  If and when the Borrower or any member of the
Controlled Group (a) gives or is required to give notice to the PBGC of any
"reportable event" (as defined in Section 4043 of ERISA) with respect to any
Plan which might constitute grounds for a termination of such Plan under Title

required to give notice of any such reportable event, (b) receives notice of
complete or partial withdrawal liability under Title IV of ERISA or (c) receives

times and places and as often as the Agent may reasonably request.

8.11  Certain Obligations Respecting Subsidiaries.

(a)  The Borrower will, and will cause each of its Subsidiaries to, take such
     action from time to time as shall be necessary to ensure that the Borrower
     at all times owns (subject only to the Lien of the Security Instruments)
     all of the issued and outstanding shares of each class of stock of each of
     its Subsidiaries.  Without limiting the generality of the foregoing, the
     Borrower shall not, and shall not permit any of its Subsidiaries to, sell,
     transfer or otherwise dispose of any shares of stock in any Subsidiary
     owned by it, or permit any of its Subsidiaries to issue any shares of stock
     of any class whatsoever to any Person other than the Borrower.  In the
     event that any such additional shares of stock shall be issued by any
     Subsidiary of the Borrower, the Borrower agrees forthwith to deliver to the
     Agent pursuant to the Security Instruments the certificates evidencing such
     shares of stock, accompanied by undated stock powers executed in blank and
     shall take such other action as the Agent shall request to perfect the
     security interest created therein pursuant to the Security Instruments.

(b)  Promptly (but in any event within thirty (30) days) following the creation
     of any Subsidiary (other than a shell acquisition subsidiary with little or
     no assets) of the Borrower following the Closing Date, or the acquisition
     of any Person by a Borrower or any Subsidiary thereof pursuant to which
     such Person becomes a direct or indirect Subsidiary of the Borrower, the
     Borrower (i) shall notify the Agent in writing of the creation or
     acquisition of such Subsidiary (and the Agent shall promptly thereafter
     notify the Lenders) and (ii) shall cause such Subsidiary to become a
     guarantor of the performance of the Obligations and to execute and deliver
     a Subsidiary Guaranty and a Subsidiary Security Agreement and such other
     documents, in form and substance satisfactory to the Agent, as the Agent
     shall reasonably require in order to confirm the authorization and
     enforceability of such guaranty.

(c)  Promptly (but in any event within thirty (30) days) following the creation
     of any Subsidiary (other than a shell acquisition subsidiary with little or
     no assets) of the Borrower following the Closing Date, or the acquisition
     of any Person by a Borrower or any Subsidiary thereof pursuant to which
     such Person becomes a direct or indirect Subsidiary of the Borrower, the
     Borrower shall (i) cause such Subsidiary to grant to the Agent for the
     benefit of the Lenders a

                                     -39-
<PAGE>

     security interest in, and a lien on, all right, title and interest of such
     Subsidiary in and to substantially all the assets of such Subsidiary
     (except for Excluded Property) and to enter into a Subsidiary Security
     Agreement in favor of the Agent for the benefit of the Lenders and such
     other documents, in form and substance satisfactory to the Agent, as the
     Agent shall reasonably require in order to confirm and perfect the
     authorization and enforceability of such security interest, and (ii)
     forthwith deliver to the Lenders pursuant to the Security Instruments the
     certificates evidencing all of the issued and outstanding shares of stock
     of such Subsidiary, accompanied by undated stock powers executed in blank
     and take such other action as the Agent shall request to perfect the
     security interest created therein pursuant to the Security Instruments. The
     Borrower shall, and shall cause the appropriate Subsidiaries of the
     Borrower to, promptly (x) execute and deliver to the Agent such number of
     copies as the Agent may specify of documents creating such Liens, (y) do
     all other things which may be necessary or which the Agent may reasonably
     request in order to confer upon and confirm to the Agent the benefits of
     such security, and (z) deliver such certificates, evidences of corporate
     action or other documents as the Agent may reasonably request, all in form
     and substance reasonably satisfactory to the Lenders, relating to the
     satisfaction of the Borrower's obligations under this Section.

8.12  Further Assurances.  The Borrower will, and will cause each of its
Subsidiaries to, execute and deliver to the Agent or any Lender any writings and
do all things necessary, effectual or reasonably requested by the Agent to carry
into effect the provisions and intent of this Agreement or any other Loan
Document.

Section 9.  Negative Covenants.

     The Borrower covenants and agrees that for so long as this Agreement is in
effect and until the Notes, together with all interest thereon and all other

     the Agent to act as its agent hereunder and under the other Loan Documents
     with such powers as are specifically delegated to the Agent by the terms
     hereof and thereof, together with such other powers as are reasonably
     incidental thereto.

                                     -48-

(b)  The Agent (which term as used in this Section 12 shall include reference to
     the Agent's Affiliates and the Agent's own and its Affiliates' officers,
     directors, employees and agents):  (a) shall have no duties or
     responsibilities except those expressly set forth in this Agreement and the
     other Loan Documents, and shall not by reason of this Agreement or any
     other Loan Document be a trustee for any Lender; (b) shall not be
     responsible to the Lenders for any recitals, statements, representations or
     warranties contained in this Agreement or any other Loan Document, or in
     any certificate or other document referred to or provided for in, or
     received by any of them under, this Agreement or any other Loan Document,
     or for the value, validity, effectiveness, genuineness, enforceability or
     sufficiency of this Agreement or any other Loan Document or any other
     document referred to or provided for herein or therein or for any failure
     by the Borrower or any other Person to perform any of its obligations
     hereunder or thereunder; (c) shall not be required to initiate or conduct
     any litigation or collection proceedings hereunder or under any other Loan
     Document except to the extent requested by the Majority Lenders, and (d)
     shall not be responsible for any action taken or omitted to be taken by
     them hereunder or under any other Loan Document or any other document or
     instrument referred to or provided for herein or therein or in connection
     herewith or therewith, except for their own gross negligence or willful
     misconduct.  The Agent may employ agents and attorneys-in-fact and shall
     not be responsible for the negligence or misconduct of any such agents or
     attorneys-in-fact selected by it with reasonable care.

(c)  Each Lender and the Issuing Bank hereby irrevocably appoints the
     Documentation Agent as documentation agent hereunder and under the other
     Loan Documents and authorizes the Documentation Agent to take such action
     on behalf of each of the Lenders and the Issuing Bank and to exercise all
     such powers on their behalf as are expressly delegated to the Documentation
     Agent by the Agent, together with such other powers as are reasonably
     incidental thereto.  The Documentation Agent shall not have any duties or
     responsibilities or any fiduciary relationship with any Lender or the
     Issuing Bank except those expressly set forth in this Agreement.

12.2  Reliance.  The Agents shall be entitled to rely upon any certification,
notice or other communication (including any thereof by telephone, telex,
telegram or cable) believed by them 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 the Agent.  As to any matters not expressly provided for by this
Agreement or any other Loan Document, each of the Agents shall in all cases be
fully protected in acting, or in refraining from acting, hereunder and
thereunder in accordance with instructions signed by the Majority Lenders (or if
required by Section 13.1 hereof, by all of the Lenders), and such instructions
of the Majority Lenders and any action taken or failure to act pursuant thereto
shall be binding on all of the Lenders.

12.3  Defaults.  The Agent shall not be deemed to have knowledge of the
occurrence of a Default (other than the non-payment of principal of or interest
on Loans) unless the Agent has received notice from a Lender or the Borrower
specifying such Default and stating that such notice is a "Notice of Default".
In the event that the Agent receives such a notice of the occurrence of a
Default, the Agent shall give prompt notice thereof to the Lenders (and shall
give each Lender prompt notice of each such non-payment).  The Agent shall
(subject to Section 12.7 hereof) take such action with respect to such Default
as shall be directed by the Majority Lenders

                                     -49-
<PAGE>

(or if required by Section 13.1 hereof, by all of the Lenders), provided that,
unless and until the Agent shall have received such directions, the Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default as it shall deem advisable in the best
interests of the Lenders.

12.4  Rights as a Lender.  Subject to the provisions of Section 4.6(b), with
respect to their Commitments and the Loans made by them, each of Fleet and
Sovereign, in their respective capacity as a Lender hereunder, shall have the
same rights and powers hereunder as any other Lender and may exercise the same
as though they were not acting as the Agent or the Documentation Agent, and the
term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include Fleet and Sovereign in their individual capacity.  The Agent and the
Documentation Agent may (without having to account therefor to any Lender)
accept deposits from, lend money to and generally engage in any kind of banking,
trust or other business with the Borrower (and any of their Affiliates) as if
they were not acting as the Agent or the Documentation Agent, and the Agent and
the Documentation Agent may accept fees and other consideration from the
Borrower (in addition to the agency fees and arrangement fees heretofore agreed
to between the Borrower and the Agent) for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

12.5  Events.  The Lenders agree to indemnify the Agents (to the extent not
reimbursed under Section 13.5 hereof), but without limiting the obligations of
the Borrower under said Section 13.5, ratably in accordance with their
respective Commitments, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against either of the Agents in any way relating to or arising out of
this Agreement or any other Loan Document or any other documents contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby (including, without limitation, the costs and expenses which the
Borrower is obligated to pay under Section 13.5 hereof but excluding, unless a
Default has occurred and is continuing, normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the enforcement
of any of the terms hereof or thereof or of any such other documents, provided
that no Lender shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the party to be indemnified
and provided further that nothing in this Section 12.5 shall require any Lender
to reimburse the Agent or the Documentation Agent for internal overhead.

12.6  Non-Reliance on Agent and Other Lenders.  Each Lender agrees that it has,
independently and without reliance on the Agents or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis of the Borrower and decision to enter into this Agreement and
that it will, independently and without reliance upon the Agents or any other
Lender, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own analysis and decisions in taking or not
taking action under this Agreement or any of the other Loan Documents.  The
Agents shall not be under any obligation to any Lender to ascertain or to
inquire as to the performance or observance by the Borrower of this Agreement or
any of the other Loan Documents or any other document referred to or provided
for herein or therein or to inspect the properties or books of the Borrower.
Except for notices, reports and other documents and information expressly
required

                                     -50-
<PAGE>

to be furnished to the Lenders by the Agents hereunder or the other Loan
Documents, the Agents shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Borrower (or any of its Affiliates) which may come
into the possession of the Agents.

12.7  Failure to Act.  Except for action expressly required of the Agent
hereunder and under the other Loan Documents, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder unless it
shall receive further assurances to its satisfaction by the Lenders of their
indemnification obligations under Section 12.5 hereof against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

12.8  Removal of Agents.  Subject to the appointment and acceptance of a
successor Agent or Documentation Agent as provided below, the Agent or
Documentation Agent may be removed at any time with or without cause by the
Majority Lenders.  Upon any such removal the Majority Lenders shall have the
right to appoint a successor Agent or Documentation Agent reasonably acceptable
to the Borrower.  If no successor Agent or Documentation Agent shall have been
so appointed by the Majority Lenders and shall have accepted such appointment
within 30 days after the Majority Lenders' removal of the retiring Agent or
Documentation Agent (the "Notice Date"), then the retiring Agent or
Documentation Agent may, on behalf of the Lenders, appoint a successor Agent or
Documentation Agent reasonably acceptable to the Borrower.  Any successor Agent
or Documentation Agent shall be (i) a Lender or (ii) if no Lender has accepted
such appointment within 30 days after the Notice Date, a bank which has an
office in Boston, Massachusetts with a combined capital and surplus of at least
$200,000,000.  Upon the acceptance of any appointment as Agent or Documentation
Agent hereunder by a successor Agent or Documentation Agent, such successor
Agent or Documentation Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Agent or
Documentation Agent, and the retiring Agent or Documentation Agent shall be
discharged from its duties and obligations hereunder.  After any retiring
Agent's or Documentation Agent's removal hereunder as Agent or Documentation
Agent, the provisions of this Section 12 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 the Agent or Documentation Agent.  The Agent or Documentation
Agent may upon notice thereof to the Borrower and the Lenders, but subject to
the prior written consent of the Borrower, resign,  in which case the procedures
for appointing a successor Agent or Documentation Agent set forth in this
Section 12.8 shall be followed as though the Agent or Documentation Agent had
been removed by the Majority Lenders.

12.9  Collateral Sub-Agents.  Each Lender by its execution and delivery of this
Agreement agrees, as contemplated by the Security Instruments, that, in the
event it shall hold any Liquid Investments referred to therein, such Liquid
Investments shall be held in the name and under the control of such Lender and
such Lender shall hold such Liquid Investments as a collateral sub-agent for the
Agent thereunder.

Section 13.  General.

13.1  Amendments, Etc.  No amendment or waiver of any provision of this
Agreement, the Notes, or any other Loan Document nor consent to any departure by
the Borrower therefrom,

                                     -51-
<PAGE>

shall in any event be effective unless the same shall be in writing and signed
by the Majority Lenders and the Borrower, and then such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given; provided that no amendment, waiver or consent shall, unless in
writing and signed by all the Lenders, do any of the following: (i) increase any
Commitment of any of the Lenders or subject the Lenders to any additional
obligations; (ii) reduce the principal of, or interest on, any Loan or fees
hereunder; (iii) postpone any date fixed for any payment of principal of, or
interest on, any Loan, or fee hereunder; (iv) change the percentage of any of
the Commitments or of the aggregate unpaid principal amount of any of the Loans,
or the number of Lenders, which shall be required for the Lenders or any of them
to take any action under this Agreement; (v) change any provision contained in
Sections 2.1, 4.12, through 4.19, 13.5 or this Section 13.1 hereof; (vi) release
any substantial portion of the security for the Obligations of the Borrower
under this Agreement or any Note, except for dispositions permitted under
Section 9.3 or release any Guarantor of any of its respective obligations under
the Guarantors' Documents; (vii) modify the definition of "Majority Lenders" as
set forth in Section 1.1; or (viii) in those provisions where consent or
approval by the Majority Lenders is required, eliminate the requirement of such
consent or approval. Notwithstanding anything in this Section 13.1 to the
contrary, no amendment, waiver or consent shall be made with respect to Section
12 without the consent of the Agent. Upon receipt of an affidavit of an officer
of Agent as to the loss, theft, destruction or mutilation of any Note or any
other security document which is not of public record and in the case of any
such loss, theft, destruction or mutilation, upon surrender and cancellation of
any such Note or other Loan Document, Borrower will issue, in lieu thereof, a
replacement Note or other Loan Document in the same principal amount thereof (to
the extent applicable) and otherwise of like tenor.

13.2  Notices, Etc.  Unless otherwise specified herein, all notices hereunder to
any party hereto shall be in writing and shall be deemed to have been given when
delivered by hand, or when sent by electronic facsimile transmission or by
telex, answer back received, or on the first Banking Day after delivery to any
overnight delivery service, freight pre-paid, or three days after being sent by
certified or registered mail, return receipt requested, postage pre-paid, and
addressed to such party at its address indicated on Schedule 2 hereto; or at any
other address specified by such party in writing except that notices to the
Agent pursuant to Section 4 shall not be effective until received by the Agent.

13.3  No Waiver; Remedies.  No failure on the part of the Agent or the Lenders
to exercise, and no delay in exercising, any right hereunder, under the Notes or
under any of the other Loan Documents shall operate as a waiver thereof; nor
shall any single or partial exercise of any right hereunder, under the Notes or
under any of the other Loan Documents preclude any other or further exercise
thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

13.4  Right of Set-off.

(a)  Upon the occurrence and during the continuance of any Event of Default,
     each Lender is hereby authorized at any time and from time to time, to the
     fullest extent permitted by law, to set off and apply any and all deposits
     (general or special, time or demand, provisional or final) at any time held
     and other indebtedness at any time owing by such Lender to or for the
     credit or the account of the Borrower against any and all of the
     obligations of the Borrower now or hereafter existing under this Agreement
     and the Notes, irrespective of whether or not such Lender shall have made
     any demand hereunder.


                                     -52-
<PAGE>

(b)  Each Lender agrees promptly to notify the Borrower, the Agent and the other
     Lenders after any such set-off and application, provided that the failure
     to give such notice shall not affect the validity of such set-off and
     application.  The rights of the Lenders under this Section 13.4 are in
     addition to other rights and remedies (including, without limitation, other
     rights of set-off) which the Lenders may have.

13.5  Expenses; Indemnification.

(a)  The Borrower shall pay on demand (i) any and all reasonable expenses
     incurred by the Agent in connection with the syndication of the Revolving
     Credit Loans; (ii) all out-of-pocket costs and expenses of the Agent in
     connection with the administration of this Agreement and the other Loan
     Documents, and any waiver or amendment of any provision hereof or thereof,
     including without limitation, the reasonable fees and disbursements of
     counsel for the Agent; and (iii) if any Default or Event of Default
     occurs, all reasonable costs and expenses incurred by the Agent and the
     Lenders, including the reasonable fees and disbursements of counsel to the
     Agent and the Lenders, and of any field examiners, auditors, appraisers,
     environmental engineers or consultants, or investment banking firms
     retained by the Agent and the Lenders in connection with such Event of
     Default or collection, bankruptcy, insolvency and other enforcement
     proceedings related thereto.  The Borrower agrees to pay, indemnify and
     hold the Agent and the Lenders harmless from, any and all recording and
     filing fees, and any and all liabilities with respect to, or resulting from
     any delay in paying, stamp, excise or other taxes, if any, which may be
     payable or determined to be payable in connection with the execution and
     delivery of or the consummation or administration of any of the
     transactions contemplated by, or any amendment, supplement or modification
     of, or any waiver or consent under or in respect of, this Agreement or the
     other Loan Documents, or any documents delivered pursuant hereto or
     thereto.

(b)  The Borrower agree to indemnify the Agent and the Lenders and their
     respective officers and directors and hold the Agent and the Lenders and
     their respective officers and directors harmless from and against any and
     all liabilities, losses, damages, reasonable costs and expenses of any kind
     (including, without limitation, the reasonable fees and disbursements of
     counsel for the Agent and each Lender in connection with any investigative,
     administrative or judicial proceeding initiated by a third party, whether
     or not the Agent or any Lender shall be designated a party thereto) which
     may be incurred by the Agent or any Lender, relating to or arising out of
     this Agreement or any other Loan Document, or the existence of any
     Hazardous Substance on, in, or under any Borrower Group Property, or any
     violation of any applicable Environmental Laws for which the Borrower or
     any Subsidiary thereof has any liability or which occurs upon any Borrower
     Group Property, or the imposition of any Lien under any Environmental Laws,
     provided that neither the Agent nor any Lender shall not have the right to
     be indemnified hereunder for its own bad faith, gross negligence or willful
     misconduct as finally determined by a court of competent jurisdiction.

(c)  The agreements in this Section 13.5 shall survive the repayment of the
     Notes, and all other amounts payable under this Agreement and the other
     Loan Documents.

                                     -53-

13.6  Successors and Assigns.

(a)  This Agreement shall be binding upon and inure to the benefit of the
     parties hereto and their respective successors and assigns except that the
     Borrower may not assign its rights or obligations hereunder or under the
     Notes without the prior written consent of all of the Lenders.

(b)  Each Lender shall have the right with the consent of the Agent and the
     Borrower (which consent in each case shall not be unreasonably withheld or
     delayed) to assign at any time any portion of its Commitment hereunder and
     its interests in the risk relating to any Revolving Credit Loans and Letter
     of Credit participations in an amount equal to or greater than $2,500,000
     to other Lenders or to banks or financial institutions acceptable to the
     Agent (each an "Assignee"), provided that any Lender which proposes to
     assign less than its total Commitment must retain a Commitment of at least
     $5,000,000.  Each Assignee shall execute and deliver to the Agent and the
     Borrower a counterpart joinder in the form of Exhibit C hereto and shall
     pay to the Agent, solely for the account of the Agent, an assignment fee of
     $3,500.  Upon the execution and delivery of such counterpart joinder, (a)
     such Assignee shall, on the date and to the extent provided in such
     counterpart joinder, become a "Lender" party to this Agreement and the
     other Loan Documents for all purposes of this Agreement and the other Loan
     Documents and shall have all rights and obligations of a "Lender" with a
     Commitment as set forth in such counterpart joinder, and the transferor
     Lender shall, on the date and to the extent provided in such counterpart
     joinder, be released prospectively from its obligations hereunder and under
     the other Loan Documents to a corresponding extent (and, in the case of an
     assignment covering all of the remaining portion of an assigning Lender's
     rights and obligations under this Agreement, such transferor shall cease to
     be a party hereto but shall continue to be entitled to the benefits of
     Section 13.5 and to any interest or fees accrued for its account hereunder
     and not yet paid); (b) the assigning Lender shall promptly surrender its
     Notes to the Agent for cancellation and delivery to the Borrower, provided
     that if the assigning Lender has retained any Commitment, the Borrower
     shall execute and deliver to the Agent for delivery to such assigning
     Lender new Notes in the aggregate amount of the assigning Lender's retained
     Commitment; (c) the Borrower shall issue to the Assignee such Notes in the
     aggregate amount of such Assignee's Commitment dated the Closing Date or
     such other date as may be specified by such Assignee; (d) this Agreement
     shall be deemed appropriately amended to reflect (i) the status of such
     Assignee as a party hereto and (ii) the status and rights of the Lenders
     hereunder; and (e) the Borrower shall take such action as the Agent may
     reasonably request to perfect or maintain the perfection of any security
     interests contemplated by this Agreement or any other Loan Document in
     favor of the Agent or Lenders, including any Assignee which becomes a party
     to this Agreement.

(c)  If the Assignee, or any Participant pursuant to Section 13.6(d)  hereof, is
     organized under the laws of a jurisdiction other than the United States or
     any state thereof, such Assignee shall execute and deliver to the Borrower,
     simultaneously with or prior to such Assignee's execution and delivery of
     the counterpart joinder described above in Section 13.6(b) and such
     Participant shall execute and deliver to the Lender granting the
     participation, a United States Internal Revenue Service Form 4224 or Form
     1001 (or any successor form), appropriately completed, wherein such
     Assignee or Participant claims entitlement to complete exemption from
     United States Federal Withholding Tax on all interest payments hereunder
     and all fees payable pursuant to any of the Loan Documents.  The Borrower
     shall not be required to pay any

                                     -54-
<PAGE>

     increased amount to any Assignee or other Lender on account of taxes to the
     extent such taxes would not have been payable if the Assignee or
     Participant had furnished the Forms referenced in this Section 13.6(b)
     unless the failure to furnish such a Form results from (i) any act of or
     failure to act by any of the Borrower or (ii) the adoption of or change in
     any law, rule, regulation or guideline affecting such Assignee or
     Participant occurring (y) after the date on which any such Assignee
     executes and delivers the counterpart joinder and complies with all other
     applicable provisions of Section 13.6(b) or (z) after the date a
     Participant is granted its participation.

(d)  Each Lender shall have the right, with the consent of the Agent (which
     consent shall not be unreasonably withheld or delayed), to grant
     participations, each in an amount equal to or greater than $2,500,000 to
     one or more banks or other financial institutions (each a "Participant") in
     all or any part of any Loans and Letter of Credit participations owing to
     such Lender and the Notes held by such Lender.  Notwithstanding the
     foregoing, any participation granted by a Lender to an Affiliate of the
     granting Lender shall not be subject to either the consent of the Agent or
     the minimum participation amount.  Each Lender shall retain the sole right
     to approve, without the consent of any Participant, any amendment,
     modification or waiver of any provision of the Loan Documents, provided
     that the documents evidencing any such participation may provide that,
     except with the consent of such Participant, such Lender will not consent
     to (a) the reduction in or forgiveness of the stated principal of or rate
     of interest on or commitment fee with respect to the portion of any
     Revolving Credit Loan subject to such participation, (b) the extension or
     postponement of any stated date fixed for payment of principal or interest
     or commitment fee with respect to the portion of any Revolving Credit Loan
     subject to such participation, or (c) the waiver or reduction of any right
     to indemnification of such Lender hereunder.  Notwithstanding the
     foregoing, no participation shall operate to increase the total Commitments
     hereunder or otherwise alter the substantive terms of this Agreement.  In
     the event of any such sale by a Lender of participating interests to a
     Participant, 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 such Notes for all purposes
     under this Agreement and the 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.  Notwithstanding anything to
     the contrary contained herein, the Borrower agrees that provisions of
     Sections 4.10 and 4.12 through 4.19 shall inure to the benefit of each
     Participant, and each Lender may enforce such provisions on behalf of any
     of its Participants; provided, however, in no event shall the Borrower be
     required to pay to the Participants of a Lender and such Lender, in the
     aggregate, any amounts in excess of the total amount they would otherwise
     be obligated to pay to such Lender under the applicable section referred
     above had such Lender not granted participations pursuant to this Section
     13.6(d).

(e)  Each Lender may furnish any information concerning the Borrower, its
     Subsidiaries and any other Loan Party in the possession of such Lender from
     time to time to assignees and participants (including prospective assignees
     and participants), provided, that such Lender shall require any such
     prospective or actual assignee or participant to maintain the
     confidentiality requirements of Section 13.15.  Notwithstanding any other
     provision of this Section 13.6, Fleet agrees for the benefit of the
     Borrower to retain for its own account a principal amount of the Loans and
     a portion of the Revolving Credit Commitment equal in the aggregate to at
     least 50% of the principal amount from time to time outstanding of the
     Loans and of the Revolving Credit Commitment.

                                     -55-
<PAGE>

(f)  Any other bank or financial institution selected by the Agent with the
     approval of the Borrower (such approval not to be unreasonably withheld or
     delayed), may, prior to the Maturity Date, become a "Lender" party to this
     Agreement for all purposes of this Agreement and the other Loan Documents
     with respect to a specified additional Commitment hereunder (each such
     Lender being referred to herein as a "New Lender"), provided that the sum
     of the aggregate Commitments of the existing Lenders and the aggregate
     Commitments of the New Lenders do not exceed $100,000,000.

     Each New Lender, the Agent and the Borrower shall execute and deliver to
the Agent an instrument of adherence in the form of Exhibit D hereto (the
"Instrument of Adherence"), which Instrument of Adherence shall specify the new
Commitment of each New Lender, and pursuant to which each New Lender, shall
agree to be bound as a Lender by the terms and conditions hereof and the other
Loan Documents. Upon the execution and delivery of such Instrument of Adherence,
(a) each New Lender shall, on the effective date thereof, become a "Lender"
party to this Agreement and the other Loan Documents and shall have all rights
and obligations of a "Lender" with a Commitment as set forth in such Instrument
of Adherence , (b) the total Revolving Credit Commitment shall be increased
accordingly, (c) each Lender shall be deemed to have consented to such increase
in the total Revolving Credit Commitment, and the addition of such New Lender or
Lenders as parties to this Agreement and the other Loan Documents with such new
Commitments, (d) this Agreement (including Schedule 2 hereto) shall be deemed
appropriately amended to reflect such changes in Commitments and the status and
rights of the Lenders hereunder, (e) the Agent shall notify the Lenders of such
increases and shall furnish the Lenders and the Borrower with a new Schedule 2
hereto, and (f) the Borrower shall issue new Notes to the New Lenders, in each
case in the amount of such New Lender's Commitment, dated the Closing Date or
such other date as may be specified by such Lender and otherwise completed in
substantially the form of Exhibit A hereto.

13.7  Severability.  Any provision of this Agreement which is prohibited,
unenforceable or not authorized in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition, unenforceability
or non-authorization without invalidating the remaining provisions hereof or
affecting the validity, enforceability or legality of such provision in any
other jurisdiction.

13.8  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
