SECTION 2.  THE LOANS

     2.1  Revolving Credit - Description:
          ------------------------------ 

          (a)  (i)  Subject to the terms and conditions of this Agreement,
Lenders hereby establish for the benefit of Borrowers a revolving credit
facility (collectively, the "Revolving Credit") which shall include Advances
extended by Lenders to or for the benefit of Borrowers from time to time
hereunder.  The 

                                      -16-
<PAGE>
 
aggregate principal amount of all Loans shall not at any time exceed the
Revolving Credit Limit. Subject to such limitation, the outstanding balance of
Loans under the Revolving Credit may fluctuate from time to time, to be reduced
by repayments made by Borrower, to be increased by future Advances which may be
made by Lenders and, subject to the provisions of Section 8 below, shall be due
and payable on the Revolving Credit Maturity Date. Borrowers shall immediately
repay any Overadvance to Agent in immediately available funds. Any Advance
requested by and made to any Borrower shall automatically be deemed requested by
and made to and for the benefit of all Borrowers regardless of which Borrower
may request a particular Advance.

              (ii) Subject to Section 8.3(a) below and the terms of this
Agreement, each Lender agrees to lend to Borrowers an amount equal to such
Lender's respective percentage (as to each Lender, the percentage of the
Revolving Credit set forth opposite its name on Schedule "A" attached hereto and
made a part hereof and referred to as its "Revolving Credit Pro Rata
Percentage") of the Advance requested by Borrowers. The outstanding Loans of
each Lender shall not exceed the respective maximum amount ("Revolving Credit
Pro Rata Share") set forth opposite its name on Schedule "A".

          (b) At Closing, Borrowers shall jointly and severally execute and
deliver a promissory note to each Lender for the total principal amount of such
Lender's Revolving Credit Pro Rata Share (collectively, as amended, modified or
replaced from time to time, the "Revolving Credit Notes").  Each Revolving
Credit Note shall evidence Borrowers' unconditional obligation to repay such
Lender for all outstanding Loans owed to such Lender under the Revolving Credit,
with interest as herein and therein provided.  Each and every Advance under the
Revolving Credit shall be deemed evidenced by the Revolving Credit Notes, which
are deemed incorporated herein by reference and made a part hereof.  Each
obligation, covenant and undertaking under this Agreement are made by Borrowers
on a joint and several basis.

          (c) The term ("Revolving Credit Term") of the Revolv ing Credit shall
expire on the Revolving Credit Maturity Date. On such date, unless having been
sooner accelerated by Agent or 

                                      -17-
<PAGE>
 
sooner terminated by Borrowers pursuant to Section 2.1(d) hereof, all
Obligations shall be due and payable in full, and after such date no further
Advances shall be available from Lenders.

          (d) Reduction or Termination.  In the event Borrowers desire to reduce
              ------------------------                                          
the Revolving Credit Limit or terminate the Revolving Credit prior to the
Revolving Credit Maturity Date, Borrowers may only effect such reduction or
termination (i) on at least 60 days prior written notice to Agent and (ii) with
full and unconditional payment of (1) in the case of a reduction, the amount of
all outstanding Obligations which exceed the amount of the Revolving Credit
Limit as reduced (in which case any and all commitments of Lenders shall be
proportionately reduced) and (2) in the case of a termination, the amount of all
outstanding Obligations, in which case any and all commitments of Lenders and
Agent hereunder shall cease.

     2.2  Letters of Credit:
          ----------------- 

          (a) As a part of the Revolving Credit and subject to its terms and
conditions Mellon in its capacity as a Lender (in such capacity, the "Issuing
Bank"), shall, on behalf of and for the benefit of all Lenders, make available
to Borrowers standby and/or merchandise letters of credit ("Letters of Credit"),
the outstanding undrawn amount of which shall not exceed, in the aggregate at
any one time, the L/C Sublimit.  Notwithstanding the foregoing, all Letters of
Credit shall be in form and substance satisfactory to Issuing Bank and Agent.
Except for Existing Letters of Credit, no Letter of Credit shall be issued with
an expiry date later than twelve (12) months from the date of issuance, but in
no event shall any Letter of Credit carry an expiry date later than the
Revolving Credit Maturity Date. Borrowers shall execute and deliver to Issuing
Bank all letter of credit agreements, including an agreement in the form
attached hereto as Exhibit 2.3, and other documents required by Issuing Bank for
such purposes, all such documents to be in form and substance satisfactory to
Issuing Bank in its sole discretion.

          (b) Immediately upon the issuance of any Letter of Credit, Issuing
Bank is deemed to have granted to each other Lender, and each other Lender is
hereby deemed to have acquired, 

                                      -18-
<PAGE>
 
an undivided participating interest (without recourse or warranty), in
accordance with each such other Lender's respective Revolving Credit Pro Rata
Percentage, in all of Issuing Bank's rights and liabilities with respect to such
Letter of Credit. Each Lender shall be directly and unconditionally obligated,
without deduction or setoff of any kind, to Issuing Bank, according to its
Revolving Credit Pro Rata Percentage, to reimburse Issuing Bank on demand for
any draws made at any time (including, without limitation, following the
commencement of any bankruptcy, reorganization, receivership, liquidation or
dissolution proceeding with respect to any Borrower) under any Letter of Credit.

          (c) Issuing Bank shall be immediately, absolutely and unconditionally
reimbursed, without offset or deduction of any kind, by Borrowers for draws made
under a Letter of Credit.  Such reimbursement shall be made, at the option of
Agent, by either a cash payment by Borrowers or by Lenders automatically making
or having deemed made (without further request or approval of Borrowers or
Lenders), a cash Advance under the Revolving Credit (regardless of whether or
not Agent has ceased making Loans to Borrowers under the Revolving Credit
following the occurrence of an Event of Default or otherwise under the terms
hereof).  All cash Advances made by Agent which constitute a reimbursement to
Issuing Bank for a draw under a Letter of Credit shall be repaid to Agent by
Lenders, without deduction or setoff of any kind, in accordance with their
respective Revolving Credit Pro Rata Percentages in accordance with Section 2.3.

          (d) Borrowers agree that all Existing Letters of Credit shall be
deemed to be Letters of Credit issued under this Agreement, shall be subject to
all of the terms and provisions of this Agreement applicable to Letters of
Credit except as otherwise expressly set forth herein to the contrary, and shall
be deemed have been issued under the L/C Sublimit and shall constitute an
Advance under Revolving Credit.

          (e) Issuing Bank shall have the right, in its absolute discretion and
whether or not an Event of Default has occurred or is continuing hereunder, to
provide the beneficiary of any of the 

                                      -19-
<PAGE>
 
Letters of Credit with notice of non-renewal in accordance with the provisions
of the Letters of Credit relating thereto.

          (f) In the event that any Letter of Credit remains outstanding on the
Revolving Loan Termination Date, Borrowers shall on said Revolving Loan
Termination Date provide Issuing Bank with cash or cash equivalents acceptable
to Issuing Bank in an amount equal to the aggregate face amount of all Letters
of Credit so outstanding, to be held by Issuing Bank as security for the
Obligations under such Letters of Credit.  This right to require cash collateral
is in addition to the right of Issuing Bank to require cash collateral upon the
occurrence of an Event of Default as set forth in Section 7 hereof.
 
     2.3  Advances, Conversions, Renewals and Payments:
          -------------------------------------------- 

          (a) Except to the extent otherwise set forth in this Agreement, all
payments of principal and of interest on the Revolving Credit, the Facility Fee,
the L/C Fees, the Expenses, the Commitment Fee, and all other charges and any
other Obligations hereunder, shall be made to Agent at its main Philadelphia
banking office, Mellon Bank Center, 1735 Market Street, Philadelphia,
Pennsylvania, in United States dollars, in immediately available funds.  Agent,
on behalf of all Lenders, shall have the unconditional right and discretion to
make a cash Advance under the Revolving Credit to pay, and/or to charge any
Borrower's operating account with Agent or any Lender for, all of the
Obligations as they become due from time to time under this Agreement including
without limitation, interest, principal, fees and reimbursement of Expenses.

          (b) (i)  Cash Advances which may be made by Lenders from time to time
under the Revolving Credit shall be made available for the use and benefit of
Borrower by crediting such proceeds to any Borrower's operating account with
Agent.

              (ii) All cash Advances subject to the Base Rate Option requested
by Borrowers under the Revolving Credit must be requested by 11:00 A.M.,
Philadelphia, Pennsylvania time, on the date such Advance is to be made, which
must be a Business Day. All cash Advances subject to the LIBOR Rate Option or
conversions 

                                      -20-
<PAGE>
 
from cash Advances subject to the Base Rate Option to the LIBOR Rate Option,
requested by Borrowers must be requested by 11:00 A.M. Philadelphia,
Pennsylvania time, three (3) Good Business Days prior to the date of such
requested cash Advance. If Borrowers do not have the required availability for
such requested Advance under the Revolving Facility on the date any such
requested Advance, then Lenders shall not be required to make such Advance. All
remittances at any time among Lenders and Agent under this Agreement shall be
made in immediately available funds by federal funds wire transfer. All requests
for a cash Advance may be made either by telephone or in writing, provided that
all telephonic requests are, upon Agent's request, to be confirmed by Borrowers
in writing on the same day, and further provided that such written confirmation
may be sent by telecopy or facsimile transmission. All written requests and
confirmations shall provide all of the information requested in the form of
Borrowing Authorization. Such requests and confirmations shall be irrevocable
and shall in each case specify: (i) whether the Loan(s) being requested are
LIBOR Based Rate Loans or Base Rate Loans; (ii) the date such Advance is to be
made; and (iii) if the Advance is a LIBOR Based Rate Loan, what Interest Period
shall apply. If no election of the LIBOR Based Option or the Base Rate Option is
made, the Advance shall be a Base Rate Loan. If no Interest Period is selected
for a LIBOR Based Rate Loan, then Borrowers shall be deemed to have selected a
one month LIBOR Interest Period. No Lender shall be obligated, for any reason
whatsoever, to advance or reimburse Agent for the share of any other Lender.

              (iii)  A.  Between each Settlement Date, Agent, in its capacity as
a Lender, shall have the discretion (without any duty or obligation regardless
of any prior practice or procedures) to make all cash Advances for the account
and on behalf of the Lenders in accordance with each Lender's Revolving Credit
Pro Rata Percentage. Periodically but not less frequently than once every week
on the same day of each week, unless such day is not a Business Day, in which
event such determination shall be made the next Business Day ("Settlement
Date"), Agent shall make a determination of the appropriate dollar amount of
each Lender's Loans based upon each such Lender's Revolving Credit Pro Rata
Percentage of all then outstanding Loans, which

                                      -21-
<PAGE>
 
amounts shall be calculated as of the close of the Business Day immediately
preceding each respective Settlement Date. Amounts of principal paid to Agent by
Borrowers from time to time, between Settlement Dates, shall be applied to the
outstanding balance of Loans made by Agent, as a Lender pursuant hereto, with
the outstanding balance of Loans made by each other Lender to be adjusted on the
next Settlement Date. Interest shall accrue and each Lender shall be entitled to
receive interest at the applicable rate only on the actual outstanding dollar
amount of its respective outstanding Loans without regard to a prospective
settlement. On each Settlement Date, Agent shall then issue to each Lender a
settlement schedule containing information with respect to the status of the
Loans and the relevant net positions of the Lenders and the outstanding balances
of their respective Loans as of the close of the Business Day preceding such
Settlement Date. Each settlement schedule shall show the net amount then owing
by each Lender to Agent or by Agent to each such Lender based upon the aggregate
cash Advances made and collections received since the most recent Settlement
Date and settlement among the Lenders and the Agent shall be made in accordance
with the direction of Agent no later than 11:00 A.M. Philadelphia, Pennsylvania
time, on each Settlement Date. To the extent Agent is not reimbursed by any
Lender on a Settlement Date in accordance with Agent's direction, Borrowers
shall immediately repay Agent on demand the amount of any reimbursement not so
made by any Lender.

                    B.  Each Lender is absolutely and unconditionally obligated
without setoff or deduction of any kind, to remit to Agent on the Settlement
Date any amount shown owing to Agent by such Lender on the settlement schedule
for such date. Agent shall also be entitled to recover any and all actual losses
and damages (including, without limitation, reasonable attorneys' fees) from any
party failing to remit payment on the Settlement Date in accordance with this
Agreement. Agent may set off the obligations of such party under this subsection
against any distributions or payments of the Obligations which such party would
otherwise make available at any time.

              (iv)  A.  In lieu of the procedure set forth in the preceding
subparagraph (iii), Agent may provide the Lenders with 

                                      -22-
<PAGE>
 
notice that Borrowers have requested a cash Advance, on the same Business Day as
such request, and request each Lender to provide Agent with such Lender's
Revolving Credit Pro Rata Percentage of such requested cash Advance prior to
Agent's making such cash Advance. Upon receipt of such notice from Agent prior
to 12:00 p.m., Philadelphia, Pennsylvania time, each Lender shall remit to Agent
its respective Revolving Credit Pro Rata Percentage of such requested cash
Advance, prior to 1:00 P.M. Philadelphia, Pennsylvania time, on the Business Day
that Agent is scheduled to make such cash Advance in accordance with Section
2.3(c)(ii) hereof. Neither Agent, Mellon nor any other Lender shall be
obligated, for any reason whatsoever, to remit or advance the share of any other
Lender. Agent shall not be required to make the full amount of the requested
cash Advance unless and until it receives funds representing each Lender's
Revolving Credit Pro Rata Percentage of such requested cash Advance, but Agent
shall advance to Borrowers that portion of the requested cash Advance equal to
the Revolving Credit Pro Rata Percentages of such requested cash Advance which
it has received from the Lenders unless such portion is not in excess of the
minimum increment for the Loan type.

                    B.   If Agent does not receive each Lender's Revolving
Credit Pro Rata Percentage of such requested cash Advance, and Agent elects,
which election may be made by Agent in its sole discretion, to make the
requested cash Advance on behalf of Lenders or any of them, Agent shall be
entitled to recover each Lender's Revolving Credit Pro Rata Percentage of each
cash Advance together with interest at a per annum rate equal to the Federal
Funds Rate during the period commencing on the date such cash Advance is made
and ending on (but excluding) the date Agent recovers such amount. Each Lender
is absolutely and unconditionally obligated, without deduction or setoff of any
kind, to forward to Agent its Revolving Credit Pro Rata Percentage of each cash
Advance made pursuant to the terms of this Agreement. To the extent Agent is not
reimbursed by such Lender, Borrowers shall repay Agent such amount immediately
on demand. Agent shall also be entitled to recover any and all actual losses and
damages (including, without limitation, reasonable attorneys' fees) from any
Lender failing to so advance upon demand of Agent. Agent may set off the
obligations of a 

                                      -23-
<PAGE>
 
Lender under this paragraph against any distributions or payments of the
Obligations which Agent would otherwise make available to such Lender at any
time.

          (v) To the extent and during the time period in which any Lender fails
to provide or delays providing its respective payment to Agent pursuant to
clause (iii) or (iv) above, such Lender's percentage of all payments of the
Obligations (but not its Revolving Credit Pro Rata Percentage of future Advances
required to be funded by such Lender) shall decrease to reflect the actual
percentage which its actual outstanding Loans bears to the total outstanding
Loans of all Lenders.

     2.4  Revolving Credit Interest:
          ------------------------- 

          (a) Base Rate Option - The unpaid principal balance of Loans under the
              ----------------                                                  
Revolving Credit, unless subject to the LIBOR Rate Option, shall bear interest,
subject to the terms hereof, at the per annum rate equal to the Base Rate ("Base
Rate Option"). Changes in the Base Rate shall become effective on the same day
as Agent announces a change in its Prime Rate.  Interest on Base Rate Loans
shall be due and payable in arrears on the first day of each calendar month
commencing the first day of the first full month following the Closing Date.
Base Rate Loans shall be in a minimum amount of Five Hundred Thousand Dollars
($500,000.00) and in $100,000 increments thereafter.
 
          (b)  LIBOR Rate Option:
               ----------------- 

               (i)  Borrowers shall have the option to have the unpaid principal
balance of Loans under the Revolving Credit bear interest at the LIBOR Based
Rate ("LIBOR Rate Option"), provided that (A) LIBOR Based Rate Loans shall be in
a minimum amount of Five Hundred Thousand Dollars ($500,000.00) and in $100,000
increments thereafter and (B) there shall be no more than ten (10) LIBOR Based
Rate Loans outstanding at any time.

               (ii) LIBOR Based Rate Loans shall be selected for a period of
either one (1), two (2), three (3) or six (6) month(s) duration, as Borrowers
may elect, during which the LIBOR 

                                      -24-
<PAGE>
 
Based Rate is applicable ("LIBOR Interest Period"); provided, however, that (a)
if the LIBOR Interest Period would otherwise end on a day which shall not be a
Good Business Day, such LIBOR Interest Period shall be extended to the next
succeeding Good Business Day, unless such Good Business Day falls in another
calendar month, in which case such LIBOR Interest Period shall end on the next
preceding Good Business Day subject to clause (c) below; (b) interest shall
accrue from and including the first day of each LIBOR Interest Period to, but
excluding the day on which any LIBOR Interest Period expires; and (c) with
respect to any LIBOR Interest Period which begins on the last Good Business Day
of a calendar month (or on a day for which there is no numerically corresponding
day in the calendar month at the end of such LIBOR Interest Period), the LIBOR
Interest Period shall end on the last Good Business Day of a calendar month.
Interest on a LIBOR Based Rate Loan shall be due and payable on the last day of
each LIBOR Interest Period (and also at the end of three (3) months with respect
to a LIBOR Interest Period of longer than three (3) months). No LIBOR Interest
Period may end after the Revolving Credit Maturity Date. Subject to all of the
terms and conditions applicable to a request that a new cash Advance be a LIBOR
Based Rate Loan, Borrowers may extend a LIBOR Based Rate Loan as of the last day
of the LIBOR Interest Period to a new LIBOR Based Rate Loan or may convert all
or a portion of the Loans subject to the Base Rate Option to a LIBOR Based Rate
Loan. If Borrowers fails to notify the Agent of the LIBOR Interest Period for a
subsequent LIBOR Based Rate Loan at least three (3) Good Business Days prior to
the last day of the then current LIBOR Interest Period of an outstanding LIBOR
Based Rate Loan, then such outstanding LIBOR Based Rate Loan shall become a loan
subject to the Base Rate Option at the end of the current LIBOR Interest Period
for such outstanding LIBOR Based Rate Loan.

               (iii) The LIBOR Rate may be automatically adjusted by Agent on a
prospective basis to take into account the additional or increased cost of
maintaining any necessary reserves for Eurodollar deposits or increased costs
due to changes in applicable law or regulation or the interpretation thereof
occurring subsequent to the commencement of the then applicable LIBOR Interest
Period, including but not limited to changes in tax laws (except changes of
general applicability in 

                                      -25-
<PAGE>
 
corporate income tax laws as they affect financial institutions) and changes in
the reserve requirements imposed by the Board of Governors of the Federal
Reserve System (or any successor), excluding any such changes that have resulted
in a payment pursuant to Section 2.9 hereof, that increase the cost to Lenders
of funding the LIBOR Based Rate Loan. Agent shall promptly give Borrowers and
each Lender notice of such a determination and adjustment, which determination
shall be conclusive as to the correctness of the fact and the amount of such
adjustment, absent manifest error. Borrowers may, by written notice to Agent,
(A) request Agent to furnish to Borrowers a statement setting forth the basis
for adjusting such LIBOR Based Rate Loans and the method for determining the
amount of such adjustment; and/or (B) prepay the LIBOR Based Rate Loans with
respect to which such adjustment is made, subject to the requirements of Section
2.9 below.

               (iv) In the event that Borrowers shall have requested the LIBOR
Rate Option in accordance with Section 2.4(b) and Agent shall have reasonably
determined that Eurodollar deposits equal to the amount of the principal of the
requested LIBOR Based Rate Loan and for the LIBOR Interest Period specified are
unavailable, impractical or unlawful, or that the rate based on the LIBOR Rate
will not adequately and fairly reflect the cost of funds of the LIBOR Based Rate
applicable to the specified LIBOR Interest Period, of making or maintaining the
principal amount of the requested LIBOR Based Rate Loan specified by Borrowers
during the LIBOR Interest Period specified, or that by reason of circumstances
affecting Eurodollar markets, adequate and reasonable means do not exist for
ascertaining the rate based on the LIBOR Rate applicable to the specified LIBOR
Interest Period, Agent shall promptly give notice of such determination to
Borrowers that the rate based on the LIBOR Rate is not available. A
determination by Agent hereunder shall be prima facie evidence of the
correctness of the fact and amount of such additional costs or unavailability.
Upon such a determination, (A) the right of Borrowers to select, convert to, or
maintain a LIBOR Based Rate Loan at the rate based on the LIBOR Rate shall be
suspended until Agent shall have notified Borrowers that such conditions shall
have ceased to exist, and (B) the Loans subject 

                                      -26-
<PAGE>
 
to the requested LIBOR Rate Option shall accrue interest in accordance with
Section 2.4(a) above.

               (v)  In the event that, as a result of any changes in applicable
law or regulation or the interpretation thereof, it becomes unlawful for a
Lender to make or to continue to fund or maintain LIBOR Based Rate Loans or to
maintain Eurodollar liabilities sufficient to fund any LIBOR Based Rate Loan
subject to the LIBOR Based Rate, then such Lender shall immediately notify Agent
who shall immediately notify the other Lenders and Borrowers thereof and such
Lender's obligations to make, convert to, or maintain a LIBOR Based Rate Loan at
the LIBOR Based Rate shall be suspended until such time as such Lender may again
cause the LIBOR Based Rate to be applicable to its share of any LIBOR Based Rate
Loans and such Lender's share of the Loans subject to the LIBOR Based Rate shall
accrue interest in accordance with Section 2.4(a) above. Immediately after
becoming aware that it is no longer unlawful for such Lender to maintain such
Eurodollar liabilities, such Lender shall notify Agent who will notify Borrower
thereof and such suspension shall cease to exist.

     2.5  Additional Interest Provisions.
          ------------------------------ 

          (a) Calculation of Interest:  Interest on the Loans, regardless of the
              -----------------------                                           
rate option, shall be based on a three hundred sixty (360) day year and charged
for the actual number of days elapsed.

          (b) Limitation on LIBOR Based Rate Loans:  Upon the occurrence and
              ------------------------------------                          
during the continuance of an Event of Default, Agent may in its sole discretion
eliminate the availability of new LIBOR Based Rate Loans.  Following the
occurrence of an Event of Default and written notice from Agent that the
Obligations have been accelerated, all existing LIBOR Based Rate Loans shall, at
Agent's option, convert to a Base Rate Loan, which conversion is independent of
Agent's rights under Section 2.5(c).

          (c) Default Rate:  After the occurrence and during the continuance of
              ------------                                                     
an Event of Default hereunder, Agent may, and shall at the direction of the
Majority Lenders, increase the per annum effective rate of interest on all Loans
outstanding under 

                                      -27-
<PAGE>
 
the Revolving Credit, including amounts drawn and not yet reimbursed by
Borrowers under Letters of Credit, regardless of the rate option, to a rate
equal to two (2%) percentage points in excess of the highest applicable interest
rate (the "Default Rate").

          (d) Continuation of Interest Charges:  All contractual rates of
              --------------------------------                           
interest chargeable on outstanding Loans, regardless of the rate option, shall
continue to accrue and be paid even after default, maturity, acceleration,
judgment, bankruptcy, insolvency proceedings of any kind or the happening of any
event or occurrence similar or dissimilar.

          (e) Applicable Interest Limitations:  In no contingency or event
              -------------------------------                             
whatsoever shall the aggregate of all amounts deemed interest hereunder and
charged or collected pursuant to the terms of this Agreement exceed the highest
rate permissible under any law which a court of competent jurisdiction shall, in
a final determination, deem applicable hereto.  In the event that such court
determines Lenders have charged or received interest hereunder in excess of the
highest applicable rate, Agent, on behalf of Lenders, shall in its sole
discretion, apply and set off such excess interest received by Lenders against
other Obligations due or to become due and such rate shall automatically be
reduced to the maximum rate permitted by such law.

          (f) Decrease in Interest Rates:  When the entire required earn-out
              --------------------------                                    
payment (approximately $31 million) to Morton Reich ("Reich Earn-Out") is either
(i) converted into or exchanged for shares of capital stock of TWI or (ii) paid
in full, in accordance with it terms, then at such time, provided no Event of
Default or Potential Default is continuing, the Base Rate and the Applicable
LIBOR Rate Margin shall each be decreased by one quarter of one percent per
annum (.25%).

     2.6  Fees:
          ---- 

          (a) Commitment Fee:  So long as the Revolving Credit is outstanding
              --------------                                                 
and has not been terminated pursuant to the terms hereof, Borrowers shall
unconditionally pay the Commitment Fee to 

                                      -28-

Agent, for the benefit of Lenders in accordance with their Revolving Credit Pro
Rata Percentage. The Commitment Fee shall be computed and paid on a monthly

first day of the first full month after the Closing Date.

          (b) Calculation of Fees:  All fees to be paid by Borrowers in

(360) day year and charged for the actual number of days elapsed.

              ---------------------                                        
benefit of Lenders in accordance with their Revolving Credit Pro Rata
Percentage, letter of credit fees, payable quarterly in advance, equal to one
percent (1%) per annum of the face amount of each Letter of Credit as a

of Issuing Bank's standard charges (including without limitation all cable and
wire transfer charges) for the account of Issuing Bank for the issuance,
amendment, negotiation/payment, extension and cancellation of each such Letter
of Credit.  All such fees are collectively, the "L/C Fees".

     2.7  Prepayments:
          ----------- 

          (a) LIBOR Based Rate Loans:  No portion of any LIBOR Based Rate Loan
              ----------------------

          (c) Proceeds of Collateral:  At Agent's request, Borrowers shall, upon

the receipt of proceeds of any Collateral following the occurrence of an Event
of Default, hold such proceeds in trust for Lenders and immediately remit in
                                                                          --
specie, all such proceeds to Agent, which funds shall, in Agent's discretion, be
------                                                                          
applied against the Obligations.

          (a) Borrowers shall indemnify, defend and hold harmless Agent and
Lenders against any and all loss, liability, cost or expense which Agent and any
Lender or Lenders may sustain or incur as a consequence of (i) any failure of
Borrowers to obtain, convert or extend any LIBOR Based Rate Loan after notice
thereof has been given to Agent; or (ii) any payment, prepayment, termination or
conversion of a LIBOR Based Rate Loan made for any reason on a date other than
the last day of the applicable LIBOR Interest Period, including, without
limitation, acceleration of the Obligations except if Agent exercises its option

thereof to Agent, for the ratable benefit of Lenders, on demand by Agent.

          (b) In the event that any modification to or change in interpretation
of any existing, or the enactment or passage of any future, law, rule,
regulation, treaty or official directive or the interpretation or application
thereof by any central bank, monetary authority or governmental authority, or
the compliance with any guideline or request of any central bank, monetary
authority or governmental authority (whether or not having the force of law)
imposes, modifies or deems applicable any deposit insurance, reserve, special
deposit, or other similar requirement with respect to deposits in or for the
account of, or loans or advances or commitment to make loans or advances by a
Lender or Letters of Credit issued or commitment to issue Letters of Credit by a
Lender and the result of any of the foregoing is to increase the costs of a
Lender, reduce the income receivable by or return on equity of Lender or impose
any expense upon Lender with respect to any advances or extensions of credit or
commitments to make advances or extensions of credit under this Agreement, such
Lender shall so notify Agent in writing.  Upon notice from Agent, 

                                      -30-
<PAGE>
 
Borrowers agree to pay such Lender the amount of such increase in cost,
reduction in income, reduced return on equity or capital, or additional expense
after presentation by such Lender of a statement concerning such increase in
cost, reduction in income, reduced return on equity or capital, or additional
expense. Such statement shall set forth a brief explanation of the amount and
such Lender's calculation of the amount (in determining such amount such Lender
may use any reasonable averaging and attribution methods), which statement shall
be conclusively deemed correct absent manifest error.

     2.10 Capital Adequacy:  If any modification to or change in
          ----------------                                      
interpretation of any existing, or the enactment or passage of any future, law,
governmental rule, regulation, policy, guideline, directive or similar
requirement (whether or not having the force of law) imposes, modifies, or deems
applicable any capital adequacy, capital maintenance or similar requirement
which affects the manner in which any Lender allocates capital resources to its
commitments (including any commitments hereunder), and as a result thereof, in
the opinion of such Lender, the rate of return on such Lender's capital with
regard to the Loans and/or its obligations hereunder is reduced to a level below
that which such Lender could have achieved but for such circumstances taking
into account such Lender's policies regarding capital adequacy, then in such
case and upon notice from Agent to Borrowers, from time to time, Borrowers shall
pay such Lender such additional amount or amounts as shall compensate such
Lender for such reduction in its rate of return.  Such notice shall contain the
statement of such Lender with regard to any such amount or amounts which shall,
in the absence of manifest error, be binding upon Borrowers.  In determining
such amount, such Lender may use any reasonable method of averaging and
attribution that it deems applicable.

where each Borrower is qualified to do business is attached hereto as Exhibit
"5.1" and made a part hereof.

          (b) The making and performance of this Agreement and the other Loan

or instrument to which any Borrower is or any Acquired Operating Company was a
party, or by which any Borrower is or any Acquired Operating Company was bound.

          ---------------------------- 

          (a) The use of the proceeds of and Borrowers' issuance of the

Regulations U, T, G and X of 

                                      -42-

the meaning of said Regulation U.

          (b) Borrowers have obtained all licenses, permits, franchises and
other governmental authorizations necessary for the ownership of their Property

SECTION 6.  AFFIRMATIVE COVENANTS

     Each Borrower covenants that until all of the Obligations to Lenders are
paid and satisfied in full and the Revolving Credit has been terminated:

     6.1  Payment of Taxes and Claims:  Each Borrower shall pay, before they
          ---------------------------                                       
become delinquent,

          (a)  all material taxes, assessments and governmental charges or
levies imposed upon it or its Property, and

          (b)  all material claims or demands of materialmen, mechanics,
carriers, warehousemen, landlords and other Persons entitled to the benefit of
statutory or common law Liens, which, if unpaid, would result in the imposition
of a Lien upon its Property; provided, however, that Borrowers shall not be
required to pay any such tax, assessment, charge, levy, claim or demand if the
amount, applicability or validity thereof shall at the time be contested in good
faith and by appropriate proceedings by Borrowers, and if Borrowers shall have
set aside on their books adequate reserves in respect thereof, in accordance
with GAAP; which deferment of payment is permissible so long as no Lien 

                                      -47-
<PAGE>
 
other than a Permitted Lien has been entered and such Borrower's title to, and
its right to use, its Property are not materially adversely affected thereby.

     6.2  Maintenance of Properties and Corporate Existence:
          ------------------------------------------------- 

          (a)  Property - Each Borrower shall (and each Borrower shall cause 
               --------    
each of its Subsidiaries to) maintain its Property in good condition and make
all renewals, replacements, additions, betterments and improvements thereto in
the ordinary course of business, as Borrowers deem reasonably necessary in good
faith in the exercise of its business judgment, and will pay and discharge when
due the cost of repairs and maintenance to its Property.

          (b)  Property Insurance - Each Borrower shall maintain insurance on 
               ------------------ 
all insurable tangible Property against fire, flood, casualty and such other
hazards (including, without limitation, extended coverage, workmen's
compensation, boiler and machinery) in such amounts, with such deductibles and
with such insurers as are customarily used by companies operating in the same
industry as Borrowers and reasonably acceptable to Agent. At or prior to
Closing, Borrowers shall furnish Agent with a schedule of all such insurance
prepared by its insurance broker, and certificates of insurance with respect
thereto (including the text of the Lender's Loss Payable Clause in favor of
Agent required below), or such other evidence of insurance as Agent may require.
Borrowers shall furnish Agent with a copy of such policy within thirty (30) days
after Closing. In the event Borrowers fail to procure or cause to be procured
any such insurance or to timely pay or cause to be paid the premium(s) on any
such insurance, Agent (on behalf of Lenders) may do so for Borrowers, but
Borrowers shall continue to be liable for the same. The policies of all casualty
insurance with respect to the Inventory and Equipment shall contain standard
Lender's Loss Payable Clauses issued in favor of Agent (on behalf of Lenders)
indicating that Agent is sole Lender Loss Payee, under which all losses
thereunder with respect to the Inventory and Equipment shall be paid to Agent
(on behalf of Lenders) as Agent's interest may appear. Such policies shall
expressly provide that the requisite insurance cannot be altered or canceled
without thirty (30) days prior written notice to Agent and shall insure Lenders

                                      -48-
<PAGE>
 
notwithstanding the act or neglect of any Borrower. Each Borrower hereby
appoints Agent as its attorney-in-fact, exercisable at Agent's option (without
any obligation to do so), to endorse any check which may be payable to such
Borrower, and to file proofs of loss with respect to any insurance claims, and,
after an Event of Default, to negotiate a settlement of any insurance claims, in
order to collect the proceeds of such insurance and any amount or amounts
collected by Agent pursuant to the provisions of this paragraph may be applied
by Agent to the Obligations. Each Borrower further covenants that all insurance
premiums due and owing under their current casualty policies have been paid.
Each Borrower also agrees to notify Agent, promptly, upon any receipt of a
notice of termination, cancellation, or non-renewal from its insurance company
of any such policy.

          (c)  Public and Products Liability Insurance - Borrowers shall 
               --------------------------------------- 
maintain, and shall deliver to Agent upon Agent's request evidence of, public
liability, products liability and business interruption insurance in such
amounts as are reasonably acceptable to Agent, but in any event not more than
are customary for companies in the same or similar businesses located in the
same or similar area.

          (d)  Financial Records - Consistent with the existing practice of TWI,
               -----------------                                                
each Borrower shall keep current and accurate books of records and accounts in
which full and correct entries will be made of all of its business transactions,
and will reflect in its financial statements adequate accruals and
appropriations to reserves, all in accordance with GAAP.  No Borrower shall
change its fiscal year end date without providing Agent thirty (30) days prior
written notice thereof, provided that Borrowers may make such change only once
prior to the Revolving Credit Maturity Date.

          (e)  Corporate Existence and Rights - Each Borrower shall do (or cause
               ------------------------------                                   
to be done) all things necessary to preserve and keep in full force and effect
its (and each of its Subsidiaries') existence, good standing in all
jurisdictions where its failure to be in good standing might result in a
Material Adverse Effect, and all of its rights, licenses and 

                                      -49-
<PAGE>
 
franchises, the absence of which might result in a Material Adverse Effect.

          (f)  Compliance with Laws - Each Borrower shall (and shall cause each
               --------------------                                            
of its Subsidiaries to) (i) be in compliance in all material respects with any
and all laws, ordinances, governmental rules and regulations, and court or
administrative orders or decrees to which it is subject, whether federal, state
or local, (including, without limitation, Environmental Laws); and (ii) obtain
and maintain any and all licenses, permits, franchises or other governmental
authorizations necessary to the ownership of its Property or to the conduct of
its business, which violation or failure to obtain or maintain causes or might
cause a Material Adverse Effect.  Each Borrower shall (and shall cause each of
its Subsidiaries to) timely satisfy all assessments, fines, costs and penalties
imposed by any governmental body against such Borrower or Subsidiary or any
Property of such Borrower or Subsidiary subject to the provisions of Section 6.1
above.

     6.3  Business Conducted:  Each Borrower shall (and shall cause each of its
          ------------------                                                   
Subsidiaries) continue in the Borrowers' (or Subsidiary's) Business using its
best efforts to maintain its customers and goodwill.  No Borrower or Subsidiary
shall engage, directly or indirectly, in any material respect, in any line of
business substantially different from the Borrowers' Business.

     6.4  Litigation:  Each Borrower, upon having knowledge thereof, shall give
          ----------                                                           
prompt notice to Agent of (a) the commencement against any Borrower or
Subsidiary of any litigation claiming from any Borrower or Subsidiary more than
$500,000 in excess of any available insurance coverage such Borrower or
Subsidiary may have for such claim for which coverage has been acknowledged by
such insurer, and (b) any other claims made against such Borrower or Subsidiary,
or investigations or proceedings commenced against such Borrower or Subsidiary
the existence of which or adverse disposition of which might have a Material
Adverse Effect.

     6.5  Taxes:
          ----- 

          (a)  Notwithstanding any other provision of this Agreement other than
6.5(f) and (g), any and all payments by Borrowers hereunder shall be made free
and clear of and without deduction for any and all present or future taxes,
levies, imposts or withholding taxes, and all liabilities with respect thereto,
excluding taxes imposed on Agent's or any Lender's net income and franchise
---------                                                                  
taxes imposed on Agent or any Lender by the United States or any jurisdiction
under the laws of which it is organized or in which an office is located or any
political subdivision thereof (all such non-excluded taxes, levies, imports,
withholding taxes and liabilities being hereinafter referred to as "Taxes"). If
Borrowers shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to any Lender or Agent (i) the sum payable shall be
increased by the amount necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
6.5) such Lender or Agent shall receive an amount equal to the sum it would have
received had no such deductions been made, (ii) Borrowers shall make such
deductions and (iii) Borrowers shall pay the full amount deducted to the
relevant taxing authority or other governmental authority in accordance with
applicable law.

          (b)  In addition, Borrowers agree to pay any present or future stamp
or documentary taxes or any other general intangible, excise or property taxes,
charges or similar levies which arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Document including, without limitation, taxes
associated with the financing statement filings in the State of Maryland
(hereinafter referred to as "Other Taxes").

          (c)  Borrowers will indemnify each Lender and Agent for the full
amount of Taxes and Other Taxes (including any Taxes or Other Taxes imposed by
any jurisdiction on amounts payable under this Section 6.5) paid by such Lender
or Agent in respect of any and all payments made by Borrowers hereunder, as the
case may be, and any liability (including penalties, interest and expenses 

                                      -51-
<PAGE>
 
other than those resulting from the failure of a Lender or Agent to pay any
Taxes or Other Taxes for which it shall have received an indemnity payment
hereunder) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted. Such indemnification shall be
made promptly after the date any Lender or Agent, as the case may be, makes
written demand therefor. If a Lender or Agent shall become aware that it is
entitled to receive a refund it shall notify Borrowers and shall, promptly after
receipt of a request by Borrowers, apply for and pursue such a refund at
Borrowers' expense. If any Lender or Agent receives a refund in respect of any
Taxes or Other Taxes for which such Lender or Agent has received payment from
Borrowers hereunder it shall promptly upon receipt repay such refund to Borrower
without interest, except to the extent interest shall have accompanied such
refund, provided that Borrowers, upon the request of such Lender or Agent,
agrees to return such refund (plus penalties, interest or other charges) to such
Lender or Agent in the event such Lender or Agent is required to repay such
refund.

          (d)  Within 45 days after the date of any payment of Taxes or Other
Taxes withheld by any Borrower in respect of any payment to any Lender or Agent,
Borrowers will furnish to the Agent, the original or a certified copy of a
receipt evidencing payment thereof.

          (e)  Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 6.5
shall survive the payment in full of principal and interest hereunder.

          (f)  On or prior to the date it becomes a party to this Agreement,
each Lender that is organized outside of the United States shall deliver to
Borrowers such certificates, documents or other evidence, as required by the
Code or Treasury Regulations issued pursuant thereto, including Internal Revenue
Service Form 4224 or 1001 and any other certificate or statement or exemption
required by Treasury Regulation Section 1.1441-4(a) or Section 1.1441-6(c) or
any subsequent version thereof, properly completed and duly executed by such
Lender establishing that such payment is (i) not subject to withholding under
the Code because such 

                                      -52-
<PAGE>
 
payment is effectively connected with the conduct by such Lender of a trade or
business in the United States or (ii) totally exempt from United States Federal
withholding tax under a provision of an applicable tax treaty. In addition, each
such Lender shall, if legally able to do so, thereafter deliver such
certificates, documents or other evidence from time to time, including, without
limitation, Internal Revenue Service Form W-8, establishing that payments
received hereunder are not subject to such withholding upon receipt of a written
request therefor from Borrowers or Agent. Unless Borrowers and Agent have
received forms or other documents satisfactory to them indicating that payments
hereunder or under the Revolving Credit Notes are not subject to United States
Federal withholding tax under an applicable tax treaty, Borrowers or Agent shall
withhold taxes from such payments at the applicable statutory rate.

          (g)  Borrowers shall not be required to pay any additional amounts to
any Lender in respect of United States Federal withholding tax pursuant to this
Section 6.5 if the obligation to pay such additional amounts would not have
arisen but for a failure by such Lender to deliver the certificate, documents or
other evidence specified in this Section 6.5 unless such failure is attributable
to (i) a change in applicable law, regulation or official interpretation thereof
or (ii) an amendment or modification to or a revocation of any applicable tax
treaty or a change in official position regarding the application or
interpretation thereof, in each case on or after the date such Lender becomes a
party to this Agreement, provided, however, that such Lender shall promptly
notify Borrowers of any such matter described in clause (i) or (ii) above upon
its learning of the same and shall thereafter take all reasonable actions
resulting from such matter including delivering certificates, documents or other
evidence as may be necessary to eliminate or reduce the amount of tax required
to be withheld.

          (h)  Any Lender claiming any additional amounts payable pursuant to
this Section 6.5 shall use reasonable efforts (consistent with legal and
regulatory restrictions) to file any certificate or document requested by
Borrowers or to change the jurisdiction of its applicable lending office if the
making of such filing or change would avoid the need for or reduce the 

                                      -53-
<PAGE>
 
amount of any such additional amounts which may thereafter accrue and would not
result in the incurrence by such Lender of any cost for which Borrowers do not
provide such security or indemnity as may be reasonably required by the Lender
to indemnify it in full for such cost and would not in the judgment of such
Lender be otherwise disadvantageous to it. Each Lender agrees with reasonable
promptness to notify Borrower of any determination which it shall make to make
any claim for additional amounts payable pursuant to this Section 6.5.

     6.6  Bank Accounts:  Each Borrower shall maintain its principal depository
          -------------                                                        
and disbursement account(s) with Agent.

     6.7  Employee Benefit Plans:  Each Borrower will (a) fund all of its
          ----------------------                                         
Pension Plans in a manner that will satisfy the minimum funding standards of
Section 302 of ERISA, or will promptly satisfy any accumulated funding
deficiency that arises under Section 302 of ERISA, (b) furnish Agent, promptly
upon Agent's request of the same, with copies of all reports or other statements
filed with the United States Department of Labor, the Pension Benefit Guaranty
Corporation ("PBGC") or the Internal Revenue Service ("IRS") with respect to all
Pension Plans, or which such Borrower, or any member of a Controlled Group (as
defined in Title IV of ERISA or the Internal Revenue Code) of which any Borrower
is also a member, may receive from the United States Department of Labor, the
IRS or the PBGC, with respect to all such Pension Plans, and (c) promptly upon
discovery advise Agent of the occurrence of any reportable event (as defined in
Section 4043 of ERISA, other than a reportable event for which the thirty (30)
day notice requirement has been waived by the PBGC) or prohibited transaction
(under Section 406 of ERISA or Section 4975 of the Internal Revenue Code) with
respect to any such Pension Plans and the action which such Borrower proposes to
take with respect thereto.  Each Borrower will make all contributions when due
with respect to any multiemployer pension plan to which it contributes and will
promptly advise Agent (i) upon its receipt of notice of the assertion against it
of a claim for withdrawal liability, (ii) upon discovery of the occurrence of
any event which, to the best of such Borrower's knowledge, would trigger the
assertion of a claim for withdrawal liability against any Borrower, and (iii)
upon the occurrence of any event 

                                      -54-
<PAGE>
 
which, to the best of such Borrower's knowledge upon its learning of the same,
would place Borrower in a Controlled Group, any member of which (including any
Borrower) may be subject to a claim for withdrawal liability, whether liquidated
or contingent, which could have a Material Adverse Effect.

     6.8  Warranties for Future Advances:  Each request by any Borrower for an
          ------------------------------                                      
Advance under the Revolving Credit in any form following the Closing Date shall
constitute an automatic representation and warranty, the truth and accuracy of
such representation and warranty of which shall be a further condition to the
funding of each Advance, by Borrowers to the effect that (without waiving,
impairing or limiting the rights of Agent and the Lenders under Section 8
below):

          (a)  There has not occurred any event or occurrence since the date of
delivery of Borrower's most recent financial statements which has resulted in,
or has had, a Material Adverse Effect.

          (b)  No Event of Default or Potential Default then exists;

          (c)  Each Advance is within and complies with the terms and conditions
of this Agreement including without limitation the notice provisions contained
in Section 2.3 hereof; and

          (d)  Each representation and warranty set forth in Section 5 of this
Agreement is then true and correct in all material respects; provided that
Borrowers may update all Exhibits and prepare additional Exhibits so that all
such Exhibits and the representations and warranties, taken together, accurately
reflect the state of any Borrower's affairs as of the date of a request for an
Advance by giving written notice thereof to Agent, and further provided that
such updated and additional Exhibits do not reflect events or conditions which
constitute violations of Section 6 or 7 hereof or otherwise reflect a Material
Adverse Effect.

     6.9  Financial Covenants:  Borrowers shall maintain and comply with the
          -------------------                                               
following financial covenants (calculated on the basis of GAAP):
 
          (a)  Net Worth:  Borrowers shall have and maintain a Net Worth, on a

Borrowers of not less than the ratio set forth below for the corresponding time
period:


Ratio                      Time Period
-----          -------------------------------------

0.3:1          As of and from the Closing Date and through the day before the

SECTION 9.  AGENT

holder of any of the Revolving Credit Notes by its acceptance thereof, hereby
irrevocably appoints and authorizes the Agent to take such action on its behalf
and to exercise such powers under this Agreement as are delegated to the Agent
by the terms hereof, together with such powers as are reasonably incidental
thereto.  Except as may be otherwise expressly provided herein, Borrowers are
hereby authorized by the Lenders to deal solely with the Agent in all
transactions which affect the Lenders under this Agreement and the Loan
Documents.  The rights, privileges and remedies accorded to the Agent hereunder
shall be exercised by the Agent on behalf of all of the Lenders.

     9.2    General Immunity.  Subject to the provisions of this Agreement, the

Obligations, including, without limitation, all transactions with respect to the
Letters of Credit, this Agreement, the Loan Documents and all related documents
in accordance with its usual banking practices.  In performing its duties as
Agent hereunder, the Agent will take the same care as it takes in connection
with loans in which it alone is interested.  However, neither the Agent nor any
of its directors, officers, agents or employees shall be liable for any action
taken or omitted to be taken by it or them hereunder or in connection herewith
except for its or their own gross negligence or willful misconduct.

                                      -74-

     9.3    Consultation with Counsel.  The Agent may consult with legal counsel
            -------------------------                                           
and any other professional advisors or consultants deemed necessary or
appropriate and selected by Agent and shall not be liable for any action taken
or suffered in good faith by it in accordance with the advice of such counsel.

     9.4    Documents.  The Agent shall not be under a duty to examine into or
            ---------                                                         
pass upon the effectiveness, genuineness or validity of this Agreement or any of
the Revolving Credit Notes or any other instrument or document furnished
pursuant hereto or in connection herewith, and the Agent shall be entitled to
assume that the same are valid, effective and genuine and what they purport to
be.  In addition the Agent shall not be liable for failing to make any inquiry
concerning the accuracy, performance or observance of any of the terms,
provisions or conditions of such instrument or document.

     9.5    Rights as a Lender.  With respect to its applicable Revolving Credit
            ------------------

rights and powers hereunder as any other Lender and may exercise the same as
though it were not the Agent, and the term "Lender" or "Lenders" shall, unless
the context otherwise indicates, include the Agent in its individual capacity.
Subject to the provisions of this Agreement, the Agent may accept deposits from,
lend money to and generally engage in any kind of banking or trust business with
Borrower and its Affiliates as if it were not the Agent.

     9.6    Responsibility of Agent.  It is expressly understood and agreed that
            -----------------------                                             
the obligations of the Agent hereunder are only those expressly set forth in
this Agreement and that the Agent shall be entitled to assume that no Event of
Default, and no event which with the passage of time, or the giving of notice,
would constitute an Event of Default, has occurred and is continuing, unless the
Agent has actual knowledge of such fact. Except to the extent Agent is required
by the Lenders pursuant to the express terms hereof to take a specific action,
the Agent shall be entitled to use its discretion with respect to exercising or
refraining from exercising any rights which may be vested in it by, or with
respect to taking or refraining from taking any action or actions that it may be
able to take under or in respect of, this Agreement and the Loan Documents.  The
Agent shall incur no liability under or in respect of this Agreement and the
Loan Documents by acting upon any notice, consent, certificate, warranty or
other paper or instrument believed by it 

                                      -75-
<PAGE>
 
to be genuine or authentic or to be signed by the proper party or parties, or
with respect to anything that it may do or refrain from doing in the reasonable
exercise of its judgment, or that may seem to it to be necessary or desirable
under the circumstances. The relationship between the Agent and each Lender is
and shall be that of agent and principal only and nothing herein shall be
construed to constitute the Agent a joint venturer with any Lender, a trustee or
fiduciary for any of the Lenders or for the holder of a participation therein
nor impose on the Agent duties and obligations other than those set forth
herein.

     9.7    Collections and Disbursements.
            ----------------------------- 

            (a) The Agent will have the right to collect and receive all 
payments of the Obligations and to collect and receive all reimbursements for
draws made under the Letters of Credit, together with all fees, charges or other
amounts due under this Agreement and the Loan Documents. On each Settlement
Date, Agent shall make a determination of the actual outstanding dollar amount
of each Lender's Loans based upon its Revolving Credit Pro Rata Percentage (or
such lesser percentage if such Lender has failed to remit a required payment to
Agent hereunder) of the outstanding principal amount of all Loans.

            (b) Agent shall pay to each Lender, on each Settlement Date, from
the interest actually received by Agent from Borrowers, a sum equal to the
interest calculated for the actual number of days elapsed on the basis of a year
of 360 days, on each Lender's outstanding balance of its Loans at the rate equal
to the applicable rate of interest chosen by Borrowers with respect to such
Lender's Revolving Credit Pro Rata Percentage of the Advances outstanding. If
Agent should for any reason receive less than the full amount of the interest or
other compensation due under the Loan Documents, each Lender's share of such
interest or compensation shall decrease in proportion to each Lender's Revolving
Credit Pro Rata Percentage.

            (c) If any such payment received by the Agent is rescinded,
determined to be unenforceable or invalid or is otherwise required to be
returned for any reason at any time, whether before or after termination of this
Agreement and the Loan Documents, each Lender will, upon written notice from the
Agent, promptly pay over to the Agent its Revolving Credit Pro Rata Percentage
of the amount so rescinded, held unenforceable or 

                                      -76-
<PAGE>
 
invalid or required to be returned, together with interest and other fees
thereon if also required to be rescinded or returned.

            (d) All payments by the Agent and the Lenders to each other
hereunder shall be in immediately available funds. The Agent will at all times
maintain proper books of account and records reflecting the interest of each
Lender in the Revolving Credit, including the Letters of Credit, in a manner
customary to the Agent's keeping of such records, which books and records shall
be available for inspection by each Lender at reasonable times during normal
business hours, at such Lender's sole expense. In the event that any Lender
shall receive any payments in reduction of the Obligations in an amount greater
than its applicable Revolving Credit Pro Rata Percentage in respect of
indebtedness to the Lenders evidenced hereby (including, without limitation
amounts obtained by reason of setoffs), such Lender shall hold such excess in
                                                                           -- 
trust (to the extent such Lender is lawfully able to do so) for Agent (on behalf
-----                                   
of all other Lenders) and shall promptly remit to the Agent such excess amount
so that the amounts received by each Lender hereunder shall at all times be in
accordance with its applicable Revolving Credit Pro Rata Percentage. To the
extent necessary for each Lender's actual percentage of all outstanding Loans to
equal its applicable Revolving Credit Pro Rata Percentage, the Lender having a
greater share of any payment(s) than its applicable Revolving Credit Pro Rata
Percentage shall acquire a participation in the applicable outstanding balances
of the Revolving Credit Pro Rata Shares of the other Lenders as determined by
Agent.

            (e) The proceeds from the sale or disposition of any Collateral
shall be applied first to Expenses incurred by Agent, then to accrued but unpaid
interest, then to unpaid fees owing to Lenders and/or Agent, then on the next
Settlement Date to the principal balance of Loans in accordance with percentage
which each Lender's respective outstanding Loans bears to the aggregate
outstanding Loans.

     9.8    Indemnification.  To the extent not promptly paid by Borrowers, the
            ---------------                                                    
Lenders hereby each indemnify the Agent ratably according to their respective
Revolving Credit Pro Rata Percentages, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed
on, incurred by or asserted against the Agent in any way relating to or arising
out of this 

                                      -77-
<PAGE>
 
Agreement or any other Loan Document or any action taken or omitted by the Agent
under or related to this Agreement or the other Loan Documents or the Loans,
provided that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting solely from the Agent's gross negligence or
wilful misconduct. Agent shall have the right to deduct, from any amounts to be
paid by Agent to any Lender hereunder, any amounts owing to Agent by such Lender
by virtue of this paragraph.

     9.9    Expenses.
            -------- 

            (a) All reasonable out-of-pocket costs and out-of-pocket expenses
incurred by Agent in connection with the creation, amendment, administration,
termination and enforcement of the Loans (including, without limitation, audit
expenses, counsel fees and expenditures to protect, preserve and defend Agent's
and each Lender's rights and interest under the Loan Documents) shall be shared
and paid on demand by Lenders pro rata based on their applicable Revolving
Credit Pro Rata Percentage.

            (b) Agent may deduct from payments or distributions to be made to
Lenders such funds as may be necessary to pay or reimburse Agent for such costs
or expenses.

            (c) In connection with reimbursement of expenses set forth in this
Section 9.9 and indemnification obligations set forth in Section 9.8, Agent
shall provide a written statement to Lenders describing such expenses or
indemnification obligations.

      9.10  No Reliance.  By execution of or joining in this Agreement, each
            -----------                                                     
Lender acknowledges that it has entered into this Agreement and the Loan
Documents solely upon its own independent investigation and is not relying upon
any information supplied by or any representations made by Agent.  Each Lender
shall continue to make its own analysis and evaluation of Borrowers.  Agent
makes no representation or warranty and assumes no responsibility with respect
to the financial condition or Property of Borrowers, any obligor or any Account
Debtor; the accuracy, sufficiency or currency of any information concerning the
financial condition, prospects or results of operations of Borrowers; or for
sufficiency, authenticity, legal effect, validity or enforceability of the Loan
Documents.  Agent assumes no responsibility or liability with respect to the
collectibility of 

                                      -78-
<PAGE>
 
the Obligations or the performance by Borrowers of any obligation under the Loan
Documents.

     9.11   Reporting.  During the term of this Agreement, Agent will promptly
            ---------                                                
furnish each Lender or make available to each Lender at Agent's office in
Philadelphia, Pennsylvania, such financial statements, reports and other
materials actually received by Agent, as any Lender may reasonably request.
Agent will notify Lenders within a reasonable period of time (not to exceed ten
(10) Business Days) after it receives actual knowledge of any Event of Default
under the Loan Documents.

     9.12   Removal of Agent.  The Agent may resign at any time upon thirty
            ----------------                                               
(30) days prior written notice thereof to Lenders and Borrowers and upon receipt
from Borrowers of written consent to such resignation, which consent shall not
be unreasonably withheld.  The Agent may be removed as Agent hereunder by the
written direction of all Lenders (exclusive of Mellon) upon the following: (i)
willful misconduct in the performance of Agent's duties or responsibilities
under this Agreement; or (ii) if a receiver, trustee or conservator is appointed
for Agent or any state or federal regulatory authority assumes management or
control of Agent or, if under applicable law, the administrative discretionary
duties and responsibilities of Agent hereunder become controlled by or subject
to the approval of any state or federal regulatory authority.  Upon any such
removal, the Majority Lenders shall have the right to appoint a successor Agent
subject to the written consent of Borrowers (not to be unreasonably withheld)
only if the successor Agent is not a Lender immediately preceding the removal of
the Agent.  Upon the acceptance of the appointment as a successor Agent
hereunder by such successor Agent, such successor Agent shall thereupon succeed
to and become vested with all rights, powers, obligations and duties of the
retiring Agent and the retiring Agent shall be discharged from its duties and
obligations hereunder.

     9.13   Action on Instructions of Lenders.  With respect to any provision
            ---------------------------------                                
of this Agreement, or any issue arising thereunder, concerning which the Agent
is authorized to act or withhold action by direction of Lenders (or as the case
may be under this Agreement, the Majority Lenders), the Agent shall in all cases
be fully protected in so acting, or in so refraining from acting, hereunder in
accordance with written instructions signed by Lenders.  Such instructions and
any action taken or failure to 

                                      -79-
<PAGE>
 
act pursuant thereto shall be binding on all Lenders and on all holders of the
Revolving Credit Notes.
 
     9.14   Several Obligations.  The obligation of each Lender is several,
            -------------------                                            
and neither the Agent nor any other Lender shall be responsible for any
obligation or commitment hereunder of any other Lender.

     9.15   Consent of Lenders to Agent's Rights.
            ------------------------------------ 

            (a) Agent shall have the sole and exclusive right to service,
administer and monitor the Loans and the Loan Documents, including without
limitation, the right to exercise all rights, remedies, privileges and options
under the Loan Documents, including without limitation the credit judgment with
respect to the making of Advances and the determination as to the basis on which
and extent to which Advances may be made and the determination as to whether
Letters of Credit should be issued, amended or extended or whether payments
should be made to the Issuing Bank for draws honored on Letters of Credit.

            (b) Notwithstanding anything to the contrary contained in
subparagraph (a) above, Agent shall not, without the prior written consent of
all Lenders: (i) extend the Revolving Credit Term or the Revolving Credit
Maturity Date, (ii) decrease any interest rate on the Revolving Credit or any
fee owing to Lenders, (iii) compromise or settle all or any material portion of
the Obligations, (iv) release any obligor from the Obligations except in
connection with termination of the Revolving Credit and full payment and
satisfaction of all Obligations, (v) modify this Section 9.15(b) or the
definition of Majority Lenders, (vi) release any material portion of the
Collateral except in connection with a sale in the ordinary course or other
permitted disposition or upon full payment of the Obligations; or (vii) increase
the Revolving Credit Limit or the Revolving Credit Pro Rata Share of any Lender;
and, except as expressly provided in this Section 9.15(b) Agent shall not,
without the prior written consent of the Majority Lenders, modify, amend or
waive any provision of this Agreement or the other Loan Documents unless
expressly permitted herein.

            (c) Notwithstanding anything to the contrary contained in
subparagraph (b) above, Agent may in its discretion waive a violation of any
provision of Section 6.9 above or withhold enforcement of action as a result of
a violation thereof, for an 

                                      -80-
<PAGE>
 
indefinite period without the consent of any Lenders if the then most recent
financial statements indicate that the deviation from the financial covenant
required to be maintained as of that date is less than five percent (5%) from
the required level.

            (d) After an acceleration of the Obligations, Agent shall have the
sole and exclusive right, with communication (to the extent reasonably
practicable under the circumstances) with all Lenders, to exercise or refrain
from exercising any and all right, remedies, privileges and options under the
Loan Documents and available at law or in equity to protect and enforce the
rights of the Lenders and collect the Obligations, including, without
limitation, instituting and pursuing all legal actions against Borrowers or to
collect the Obligations, or defending any and all actions brought by Borrowers
or other Person;  or incurring Expenses or otherwise making expenditures to
protect the Loans, the Collateral or Lenders' rights or remedies.

            (e) To the extent Agent is required to obtain or otherwise elects to
seek the consent of Lenders to an action Agent desires to take, if any Lender
fails to notify Agent, in writing, of its consent or dissent to any request of
Agent hereunder within five (5) Business Days of such Lender's receipt of such
request, such Lender shall be deemed to have given its consent thereto.

            (f) Any amendment to Section 9 of this Agreement shall not require
Borrowers' consent.

     9.16   Participations and Assignments:  Each Lender may at any time:
            ------------------------------                               

            (a) grant participations of its Revolving Credit Pro Rata Percentage
of Loans or in and to its interests under this Agreement (collectively,
"Participations") to any other lending office of such Lender or to any other
bank, lending institution or other entity which such Lender determines has the
requisite sophistication to evaluate the merits and risks of investments in
Participations ("Participants"); provided however that:  (i) all amounts payable
by Borrowers to such Lender hereunder and voting rights of such Lender hereunder
shall be determined as if such Lender had not granted such Participation; and
(ii) any agreement pursuant to which such Lender may grant a Participation (A)
shall provide that such Lender is not delegating and therefor shall retain the
sole right and responsibility to exercise its rights and privileges including,
without limitation, the right to 

                                      -81-
<PAGE>
 
approve any amendment, modification or waiver of any provisions of this
Agreement, provided, however that as between such Lender and its Participant
such Lender may agree to consult with and obtain the approval of its Participant
regarding any amendment, modification or waiver of any provision set forth in
Section 9.15(b); and (B) shall not release or discharge such Lender from its
duties and obligations, which shall remain absolute, to make Advances hereunder;
and

            (b) assign all or any portion of its Revolving Credit Pro Rata
Percentage of Loans and its right, title and interest therein or in and to this
Agreement (accompanied by an equivalent delegation of its duties and obligations
hereunder) to another Lender or any affiliate of a Lender, or to any other bank
or financial institution having capital of at least $500,000,000, in each case
with the prior written consent of the Agent, so long as (i) such assigning
Lender pays Agent a transfer and processing fee of $3,500, (ii) the assignor and
assignee execute an assignment in the form of Exhibit 9.16 attached hereto, and
(iii) following such assignment, each Lender hereto has a minimum Revolving
Credit Pro Rata Share of $5,000,000 (other than any assigning Lender which has
assigned its entire Revolving Credit Pro Rata Share).  Upon request of Agent,
Borrowers shall execute a replacement Revolving Credit Note (identical in form
to the notes being delivered to the Lenders on the Closing Date) to the assignee
Lender and the assignor Lender in the amount of their respective Revolving
Credit Pro Rata Shares.  Notwithstanding anything to the contrary contained
herein, each Lender may at any time collaterally assign all or any portion of
its rights under this Agreement and its Revolving Credit Note to any Federal
Reserve Bank to secure overnight deposits, provided that no such assignment
shall release the assignor Lender from its obligations hereunder.

SECTION 10.  MISCELLANEOUS

     10.1   GOVERNING LAW:  THIS AGREEMENT, AND ALL RELATED AGREEMENTS AND
            -------------                                                 
DOCUMENTS, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE SUBSTANTIVE
LAWS OF THE COMMONWEALTH OF PENNSYLVANIA.  THE PROVISIONS OF THIS AGREEMENT, THE
OTHER LOAN DOCUMENTS AND ALL OTHER AGREEMENTS AND DOCUMENTS REFERRED TO HEREIN
ARE TO BE DEEMED SEVERABLE, AND THE INVALIDITY OR UNENFORCEABILITY OF ANY
PROVISION SHALL NOT AFFECT OR IMPAIR THE 

                                      -82-
<PAGE>
 
REMAINING PROVISIONS WHICH SHALL CONTINUE IN FULL FORCE AND EFFECT.

     10.2   Integrated Agreement:  The Revolving Credit Notes, the other Loan
            --------------------                                             
Documents, all related agreements, and this Agreement shall be construed as
integrated and complementary of each other, and as augmenting and not
restricting Lenders' and Agent's rights and remedies.  If, after applying the
foregoing, an inconsistency still exists, the provisions of this Agreement shall
constitute an amendment thereto and shall control.

     10.3   Waivers, Release and Indemnification:
            ------------------------------------ 

            (a) No omission or delay by Agent or Lenders in exercising any
right or power under this Agreement or any related agreements and documents will
impair such right or power or be construed to be a waiver of any default, or
Event of Default or an acquiescence therein, and any single or partial exercise
of any such right or power will not preclude other or further exercise thereof
or the exercise of any other right, and as to Borrowers no waiver will be valid
unless in writing and signed by Agent and then only to the extent specified.

            (b) Each Borrower releases and shall indemnify, defend and hold
harmless Agent and Lenders, and their respective officers, employees and agents,
of and from any claims, demands, liabilities, obligations, judgments, injuries,
losses, damages and costs and expenses (including, without limitation,
reasonable legal fees) resulting from (i) acts or conduct of Borrower under,
pursuant or related to this Agreement and the other Loan Documents, (ii) any
Borrower's breach or violation of any representation, warranty, covenant or
undertaking contained in this Agreement or the other Loan Documents, and (iii)
any Borrower's failure to comply with any or all laws, statutes, ordinances,
governmental rules, regulations or standards, whether federal, state or local,
or court or administrative orders or decrees, (including without limitation
environmental laws, etc.) and all costs, expenses, fines, penalties or other
damages resulting therefrom, unless resulting from acts or conduct of Lenders
constituting wilful misconduct or gross negligence.  The obligations of
Borrowers under this Section 10.3(b) shall survive the occurrence of any and all
events whatsoever, including without limitation, payment of the Obligations or
investigation by or knowledge of Lenders.

                                      -83-
<PAGE>
 
            (c) Each Borrower expressly waives presentment for payment, demand,
notice of dishonor, protest, notice of protest, diligence of collection, and any
other notice of any kind, and hereby consents to any number of renewals and
extensions of time of payment hereof, which renewals and extensions shall not
affect the liability of any party hereto.  Borrowers further agree that Agent
may accept, by way of compromise or settlement, from any one or more of the
parties liable hereunder a sum or sums less than the amount of the Obligations,
and may give releases to such parties without affecting the liability of any
other party for the unpaid balance.  Any such renewals or extensions may be made
and any such partial payments accepted or releases given without notice to any
such party.

            (d) Each Borrower hereby waives and releases all errors, defects and
imperfections in any proceedings instituted by Agent under the terms of this
Agreement, or of any of the other Loan Documents, as well as all benefit that
might accrue to Borrower by virtue of any present or future laws exempting the
Property, or any other property, real, personal or mixed, or any part of the
proceeds arising from any sale of such property, from attachment, levy or sale
under execution, or providing for any stay of execution, exemption from civil
process, or extension of time for payment.  Borrowers agree that any real estate
that may be levied upon pursuant to a judgment obtained by virtue hereof, or
upon any writ of execution issued thereon, may be sold upon any such writ in
whole or in part in any order desired by Lender.

     10.4   Time:  Whenever Borrowers shall be required to make any payment,
            ----                                                            
or perform any act, on a day which is not a Business Day, such payment may be
made, or such act may be performed, on the next succeeding Business Day except
with respect to the repayment of LIBOR Based Rate Loans as set forth in Section
2.4(b)(ii).  Time is of the essence in the performance under all provisions of
this Agreement and all related agreements and documents.

     10.5   Expenses of Agent and Lenders:  At Closing and from time to time
            -----------------------------                                   
thereafter, Borrower will pay all reasonable expenses of Agent on demand
(including, without limitation, search costs, audit fees, and the reasonable
fees and expenses of legal counsel for Agent) relating to this Agreement, and
all related agreements and documents, including, without limitation, expenses
incurred in the analysis, negotiation, preparation, closing, administration,
enforcement of this Agreement and the 

                                      -84-

other Loan Documents, the enforcement, protection and defense of the rights of
Agent and Lenders in and to the Loans and Collateral or otherwise hereunder, and
any expenses relating to extensions, amendments, waivers or consents pursuant to
the provisions hereof, or any related agreements and documents or relating to
agreements with other creditors, or termination of this Agreement. Borrowers
further agree to pay, or reimburse Lenders for, all reasonable out-of-pocket
costs and expenses, including without limitation attorneys' fees, incurred in
connection with the enforcement, protection and defense of their rights in and
to the Loans and the Collateral or otherwise hereunder, following acceleration
of the Obligations after the occurrence of an Event of Default hereunder.
Collectively all of the foregoing are referred to as the "Expenses."

     10.6   Brokerage:  This transaction was brought about and entered into
            ---------                                                      
by Agent, Lenders and Borrowers acting as principals and without any brokers,
agents or finders being the effective procuring cause hereof.  Borrowers
represent that they have not committed Agent or any Lender to the payment of any
brokerage fee, commission or charge in connection with this transaction. If any
such claim is made on Agent or any Lender by any broker, finder or agent or
other person, each Borrower hereby indemnifies, defends and saves such party
harmless against such claim and further will defend, with counsel satisfactory
to Agent, any action or actions to recover on such claim, at Borrowers' own cost
and expense, including such party's reasonable counsel fees.  Borrowers further
agree that until any such claim or demand is adjudicated in such party's favor,
the amount demanded shall be deemed a liability of Borrowers under this
Agreement.

sole discretion, shall have the right at any time, and from time to time, if
Borrowers fail to timely perform, to: (a) pay for the performance of any of the
Obligations hereunder, and (b) discharge taxes or Liens, at any time levied or
placed on any of any Borrower's Property in violation of this Agreement unless
such entity is in good faith with due diligence by appropriate proceedings
contesting such taxes or Liens and maintaining proper reserves therefor in
accordance with GAAP. Expenses and advances shall be added to the Revolving
Credit, bear interest at the same rate applied to the Revolving Credit, until
reimbursed to Agent. Such payments and advances made by Agent shall not be
construed as a waiver by Agent or Lenders of an Event of Default under this
Agreement.

Agent, that they have properly deposited or paid, as required by law, all
withholding taxes and all federal, state, city, county or other taxes due up to
and including the date of the requested Advance. Copies of deposit slips showing
payment shall likewise constitute satisfactory evidence for such purpose. In the
event that any lien, assessment or tax liability against Borrowers shall arise
in favor of any taxing authority, whether or not notice thereof shall be filed
or recorded as may be required by law, Agent shall have the right (but shall not
be obligated, nor shall Agent or any Lender hereby assume the duty) to pay any
such lien, assess assessment or tax liability by virtue of which such charge
shall have arisen; provided, however, that Agent shall not pay any such tax,
assessment or lien if the amount, applicability or validity thereof is being
contested in good faith and by appropriate proceedings by such entity. In order
to pay any such lien, assessment or tax liability, Agent shall not be obliged to
wait until said lien, assessment or tax liability is filed before taking such
action as hereinabove set forth. Any sum or sums which Agent (shared ratably by
Lenders) shall have paid for the discharge of any such lien shall be added to
the Revolving Credit and shall be paid by Borrower to Agent with interest
thereon, upon demand, and Agent shall be subrogated to all rights of such taxing
authority against Borrower.
