     1.2   Calculations and Financial Data.
           -------------------------------

                  Except as otherwise provided in this Agreement, calculations
under this Agreement shall be subject to the following:

           1.2.1  Calculations made pursuant to this Agreement and financial
data delivered hereunder and terms referred to herein shall be prepared and
interpreted both as to classification of items and as to amounts in accordance
with GAAP.

           1.2.2  It shall be assumed that any Indebtedness constituting
Guaranties will require payments of principal in the amounts as called for in
the underlying obligation which is the subject of such Guaranty subject to any
express limitations set forth in such Guaranty (it being understood that neither

     2.1   Borrowings
           ----------

           2.1.1  Commitment to Lend.
                  ------------------

                  (a)  Subject to and upon the terms and conditions set forth in
this Agreement, the Lenders shall make advances ("RC Loans") to the Borrower
                                                  --------
until the Maturity Date in an aggregate principal amount not to exceed at any
time outstanding Fifty Million Dollars ($50,000,000) (as the same may be reduced
pursuant to the terms of this Agreement, the "Commitment"); provided however,
                                              ----------    -------- -------
that (a) the aggregate amount of the Commitment available

                                     -18-
<PAGE>
 
for borrowing at any time shall not exceed the amount of the Available RC
Commitment; and (b) the amount and percentage of the Commitment which each
Lender is obligated to lend in respect of RC Loans shall not exceed at any time
the amount or percentage set forth opposite the name of such Lender on Schedule
                                                                       --------
2.1 attached hereto (as supplemented and amended by giving effect to the
- ---
assignments contemplated in Section 12.5). (Any Lender's share of the Commitment
is sometimes referred to in this Agreement as such Lender's Commitment). Within
the foregoing limits, and subject to the terms and conditions set forth in this
Agreement until the Maturity Date, the Borrower may borrow under this Subsection
2.1.1, repay or prepay such advances, and reborrow under this Subsection 2.1.1.

                  (b) Swing Loans. Subject to and upon the terms and conditions
set forth in this Agreement, the Swing Loan Lender shall make advances ("Swing
                                                                         -----
Loans")to the Borrower until the Maturity Date, in an aggregate unpaid principal
- -----
amount not exceeding at any time $4,000,000.00 provided, however, that no Swing
                                               --------
Loan shall be made at any time in an amount in excess of the Available
Commitment at such time and provided further, that the Swing Loan Lender shall
                            --------
not be obligated to lend if the conditions set forth in Section 4.2 are not
satisfied or if any lender provides the Swing Loan Lender with a notice referred
to in clause (B) of Section 2.4(e) below. (The foregoing proviso is not intended
to limit the generality of the provisions of Section 4.2). Each Swing Loan shall
be in such amount (not to exceed the Available Commitment) and at such rate as
is agreed upon by the Swing Loan Lender and the Borrower. All Swing Loans shall
be disbursed by the Swing Loan Lender in Dollars in funds immediately available
to the Borrower by crediting such account of the Borrower as may have been
agreed to by the Borrower and the Swing Loan Lender.

           2.1.2  Reduction of Commitment.
                  -----------------------

                  (a) Mandatory Reductions In Connection With Dispositions. In
the event that any of the Net Proceeds of any sale or disposition of assets
(including, without limitation, capital stock other than an issuance of capital
stock of the Borrower that is not prohibited by the terms of this Agreement) by
the Borrower or any of its Subsidiaries other than in the ordinary course of
business made pursuant to Section 9.6 have not been reinvested, pursuant to
Acquisitions described in Section 9.3 in Permitted Businesses in a manner not
prohibited by the terms of this Agreement within the one-year period following
such sale or disposition, the Borrower shall, within 30 days following the end
of such one-year period, reduce the amount of the Commitment by an amount equal
to such excess. At least five (5) Business Days prior to the date that a
Commitment reduction pursuant to this Subsection 2.1.2(a) is to occur, the
Borrower shall give the Lenders prior written notice thereof, indicating whether
such reduction shall be accompanied by a prepayment of Loans pursuant to
Subsection 2.4.2 below.

                  (b) Reductions in Connection with Certain Insurance Proceeds.
At any time that the Borrower and/or its Subsidiaries receive insurance proceeds
in one transaction or in a series of related transactions in excess of One
Million Dollars, the Borrower shall reduce the amount of the Commitment by an
amount equal to such excess unless the Borrower is able to demonstrate to the
Lenders that it shall apply such proceeds to the intended use to continue the
operations of the business. The Borrower shall promptly notify the Lenders at
any time that it

                                     -19-
<PAGE>
 
has received insurance proceeds in excess of One Million Dollars during a six
month period. The notice shall specify whether the Borrower intends to reduce
the Commitment or apply the proceeds as aforesaid and, if the latter, shall
describe the intended use with specificity. If no Lender objects to the intended
application within five (5) Business Days of receipt of such notice, the
Borrower shall apply the proceeds as specified in the notice. If any Lender
objects to such application, then all of the Lenders shall be asked to consent
in writing to such intended application and, if the Requisite Lenders so consent
within ten (10) Business Days of the date that they are so asked, the Borrower
shall apply the proceeds as specified in the notice and, if the Requisite
Lenders do not so consent within that period, then the Commitment shall be
reduced.

                  (c) Voluntary Reductions. The Borrower shall have the right at
any time and from time to time upon five (5) Business Days' prior written notice
to the Agent to permanently reduce in amounts equal to One Million Dollars
($1,000,000) or integral multiples of Five Hundred Thousand Dollars ($500,000)
in excess thereof, or terminate, the Commitment, without penalty or premium
(except that if any such voluntary reduction in the Commitment would require the
prepayment of any LIBOR Loan (pursuant to Subsection 2.4.2) prior to the last
day of the applicable Interest Period, it shall be accompanied by all amounts
due under Subsection 2.6.4 below).

                  (d) Termination of Commitment. Unless terminated earlier
pursuant to the terms of this Agreement, the Commitment shall terminate on the
Maturity Date.

     2.2   The Notes.
           ---------

           The aggregate amount of each Lender's share of the Commitment and
Loans shall be evidenced by a promissory note to be issued by the Borrower to
such Lender in substantially the form attached hereto as Exhibit A and the
                                                         ---------
aggregate amount of the Swing Loans shall be evidenced by a promissory note in
such form as the Swing Loan Lender and Borrower shall agree upon (collectively,
as the same may be amended, modified or supplemented from time to time in
accordance with the terms hereof and together with each replacement thereof,
"Notes" or individually a "Note"), the principal and unpaid interest of which,
 -----                     ----
and all unpaid fees and other sums of any nature due under or in connection with
which, (to the extent not due and payable before) shall be due and payable on
the Maturity Date.

     2.3   Manner of Effecting an RC Borrowing. The provisions of this
           -----------------------------------
Section 2.3 shall apply only to RC Loans.

           2.3.1  Borrowing Notice. Each borrowing of a Base Rate Loan shall be
                  ----------------
in the minimum amount of One Million Dollars ($1,000,000) and integral multiples
of Five Hundred Thousand Dollars ($500,000) in excess of such minimum amount.
Each borrowing of a LIBOR Loan shall be in a minimum amount of Two Million
Dollars ($2,000,000) and integral multiples of Five Hundred Thousand Dollars
($500,000) in excess of such minimum amount. To effect a borrowing, the Borrower
shall give the Agent written notice in the form annexed to this Agreement as
Exhibit B or in such other form as the Agent and the Borrower may agree upon,
- ---------
specifying the amount and date of each intended borrowing, the manner in which
the same shall

                                     -20-
<PAGE>
 
be disbursed, which notice (a) in the case of any Base Rate Loan, shall be given
no later than 10:00 a.m. (Philadelphia, Pennsylvania time) on the date of such
borrowing, and (b) in the case of any LIBOR Loan, shall be given no later than
11:00 a.m. (Philadelphia, Pennsylvania time) three (3) Business Days prior to
the date of such borrowing and shall be accompanied by an Election for LIBOR
Loan pursuant to Subsection 2.5.4 below. Each such notice of borrowing (i) shall
contain a certification by the Borrower that, both before and after giving
effect to the proposed borrowing, the Borrower is in compliance with the
covenants set forth in Article 7 below and that no other Default or Event of
Default exists or would be created thereby and (ii) shall certify as to the
outstanding amount of Swing Loans. The Agent shall be entitled to (but not
required to) rely on the information set forth in the Borrowing Notice provided
by the Borrower even if it has received contrary information from some other
source including, without limitation, from the Swing Loan Lender.

           2.3.2  Funding Procedure. The Agent in turn shall give prompt written
                  -----------------
or telephonic notice (confirmed in writing) to each Lender of its pro rata share
of the requested Loan, the interest rate and the scheduled date of the funding.
After receipt of such notice, each Lender shall make such arrangements as are
necessary to assure that its pro rata share of the funding shall be immediately
available (in U.S. Dollars) to the Agent no later than 2:00 p.m. Philadelphia,
Pennsylvania time, on the date on which the funding is to occur. After receipt
of the funds, subject to the satisfaction of the conditions precedent set forth
in Sections 4.2 (with respect to all fundings) and 4.1 (with respect to the
initial funding), and subject to the other conditions set forth herein, the
Agent shall disburse the amount of such borrowing in accordance with
instructions in the Borrower's borrowing notice.

           2.3.3  Permitted Assumptions by Agent.
                  ------------------------------

                  (a) Unless the Agent shall have received notice from a Lender
prior to 12:00 noon (Philadelphia time) on the date of any RC Loan that such
Lender will not make available to the Agent such Lender's ratable portion of
such Loan, the Agent may assume that such Lender has made or will make such
portion available to the Agent on the date of such Loan. The Agent may in its
sole discretion and in reliance upon such assumption make available to the
Borrower on such date a corresponding amount. If a Lender has not or does not
make available to the Agent the full amount on the day of the advance, the Agent
may advance such corresponding amount and such Lender agrees to repay to the
Agent on demand such corresponding amount together with interest thereon, for
each day from the date such amount is made available to the Borrower until the
date such amount is repaid by such Lender to the Agent at the Federal Funds Rate
provided, however, that if such Lender shall fail to make available to the Agent
- --------
the full amount of such Lender's share of the advance within two (2) Business
Days of the date it shall have received notice from the Agent that its share of
the advance has not been received, interest shall accrue (from such second
Business Day after notice is received) at a rate equal to the rate payable by
the Borrower on the corresponding Loan.

                  (b) If such Lender shall reimburse the Agent for an amount
advanced by the Agent pursuant to the preceding paragraph (a), such amount shall
constitute such Lender's portion of the applicable Loans for purposes of this
Agreement. If such Lender does not

                                     -21-
<PAGE>
 
reimburse such corresponding amount immediately upon the Agent's demand
therefor, interest shall be payable as set forth in paragraph (a). The failure
of any Lender to fund its portion of any Loans shall not relieve any other
Lender of its obligation, if any, hereunder to fund its respective portion of
the Loans on the funding date, but no Lender shall be responsible for any such
failure of any other Lender.

           (c) If the Agent advances any funds pursuant to this Subsection 2.3.5
in respect of another Lender's Commitment and whether or not the relevant Lender
thereafter reimburses the Agent, any contractual interest payable on such amount
by the Borrower hereunder for the period commencing on the date such amount was
made available by the Agent until the date the relevant Lender reimbursed the
Agent shall be payable to the Agent and not such Lender and, in addition, such
Lender shall pay the Agent the amounts referred to in paragraph (a) above and
shall reimburse the Agent for any costs, losses or expenses incurred therewith
as well as a $250 fee to compensate the Agent for its efforts in connection
therewith.

           (d) In the event that, at any time (other than during a period when a
Default or Event of Default has occurred and is continuing) a Lender for any
reason fails or refuses to fund its portion of a Loan, then, until such time as
such Lender has funded its portion of such Loan (which late funding shall not
absolve such Lender from any liability it may have), such non-funding Lender
shall not have the right to vote regarding any issue on which voting is required
or advisable under this Agreement or any other Loan Document, and the amount of
the Commitment or Loans of such Lender shall not be counted as outstanding for
purposes of determining "Requisite Lender" hereunder.

           (e) Without prejudice to the survival of any other remedies
hereunder, if any Lender fails to make available to the Agent the full amount of
such Lender's share of the advance within two (2) Business Days of the date it
shall have received notice from the Agent that its share of the advance has not
been received, the Borrower or the Agent may require that such Lender transfer
all of its right, title and interest under this Agreement, such Lender's Note
and each other Loan Document to any Eligible Institution identified by the
Borrower (with the consent of the Agent (which consent shall not be unreasonably
withheld)) or by the Agent, subject to the following: (i) such proposed
transferee shall agree to assume all of the obligations of the transferor Lender
for consideration equal to the outstanding principal amount of such transferor
Lender's Loans, together with interest thereon to the date of such transfer, and
(ii) satisfactory arrangements shall be made for payment to such transferor
Lender of all other amounts payable hereunder to such Lender on or prior to the
date of such transfer (including any fees accrued hereunder, except any amounts
that would be payable under Subsection 2.6.4 as a result of assigning rights and
obligations in respect of any LIBOR Loans on a day other than the last day of
the applicable Interest Period, which amounts shall be forfeited by the
transferor). In the event that any transfer is made pursuant to this paragraph
(e), the Agent shall be entitled to a processing and recording fee of $3,500
payable in equal share by the transferor and the transferee.

                                     -22-
<PAGE>
 
           (f) The provisions of this Subsection 2.4.5 shall in no way serve to
limit or modify a Lender's obligation to fund Loans to the Borrower as otherwise
provided in this Agreement.

     2.3A  Obligations Suspended During Default; Obligations Several.
           ---------------------------------------------------------

           2.3A.1 Obligations Suspended During Default. The Lenders shall not be
                  ------------------------------------
obligated to comply with a borrowing notice if there shall then exist an Event
of Default or a Default.

           2.3A.2 Several Obligations to Lend. Each Lender is severally bound by
                  ---------------------------
this Agreement, but there shall be no joint obligation under this Agreement. The
failure of any Lender to make any Loan to be made by it on the date specified
for the Loans shall not relieve any other Lender of its obligation to make its
Loan on such date.

     2.4   Prepayments and Repayments.
           --------------------------

           2.4.1 Voluntary Prepayments of Loans. Except as specifically set
                 ------------------------------
forth in Section 2.6.4 (Breakage) or elsewhere in this Agreement, the Borrower
shall be permitted to prepay the RC Loans at any time without penalty or premium
subject to the following:

                 (a) The Borrower shall provide the Agent with written notice
(or telephonic notice confirmed in writing) no later than 10:00 a.m.
(Philadelphia, Pennsylvania time) on the Business Day of a proposed prepayment
of any Base Rate Loan and at least three (3) Business Days prior written notice
(or telephonic notice confirmed in writing) of its intention to prepay any LIBOR
Loan, in each case specifying the amount and date of such prepayment.

                 (b) Each prepayment of some, but not all, of the Base Rate
Loans shall be in a minimum amount equal to One Million Dollars ($1,000,000.00)
and integral multiples of Five Hundred Thousand Dollars ($500,000.00) in excess
of such minimum amount and each prepayment of some, but not all, of the LIBOR
Loans shall be in a minimum amount equal to Two Million Dollars ($2,000,000.00)
and integral multiples of Five Hundred Thousand Dollars ($500,000.00) in excess
of such minimum amount.

           Swing Loans may be prepaid at any time on such terms and conditions
as shall be specified by the Swing Loan Lender.

           2.4.2 Prepayments of Loans In Connection With Commitment Reductions.
                 -------------------------------------------------------------
The amount of the outstanding principal amount of the Loans may not, at any
time, exceed the amount of the Commitment. Therefore, upon the effective date of
each reduction in the Commitment (whether scheduled, mandatory or voluntary),
the Borrower shall pay to the Agent for the benefit of the Lenders the principal
amount of the RC Loans to the extent, if any, that the aggregate principal
amount of the Loans then outstanding exceeds the amount of the Commitment as so
reduced. If after the RC Loans are repaid in full, the outstanding amount of the
Loans still would exceed the amount of the Commitment, then the Borrower shall
repay such 

                                     -23-
<PAGE>
 
amount of the Swing Loans as is necessary to cause the outstanding amount of the
Loans to be no greater than the amount of the Commitment.

           2.4.3 Payments of Loans on Maturity Date. Notwithstanding anything
                 ----------------------------------
else provided herein, all outstanding amounts of principal on the Loans,
together with all interest and fees related thereto and all other amounts
payable under the Loan Documents, if not due and payable before, shall be due
and payable on the Maturity Date.

           2.4.4 Application of Prepayments and Repayments. Unless otherwise
                 -----------------------------------------
provided in this Agreement, repayments and prepayments shall be applied first to
costs, indemnities and fees (to the extent then payable) then to interest (to
the extent then payable) and then to principal with respect to Base Rate Loans,
and then to principal with respect to LIBOR Loans and among such LIBOR Loans
first to such Loans with the earliest expiring Interest Periods and thereafter
to such LIBOR Loans in chronological order of the expiration of their Interest
Periods.

           2.4.5 Interest and Breakage Costs on LIBOR Loans. The Borrower shall,
                 ------------------------------------------
concurrently with any prepayment of any LIBOR Loans, pay the full amount of all
interest accrued on such Loans and, if on a day other than the last day of the
applicable Interest Period, pay such amounts as are required by Subsection 2.6.4
below (Breakage).

           2.4.6 Special Provisions Respecting Swing Loans.
                 -----------------------------------------

                 (a) Administration. The Swing Loan Lender shall be solely
responsible for the administration of the Swing Loans. The Agent shall not be
responsible for the administration of such Loans unless and until they are
converted to RC Loans.

                 (b) Request for Borrowing. The Borrower shall give the Swing
Loan Lender notice of a request for a Swing Loan in such time, place and manner
as is agreed upon by the Swing Loan Lender and the Borrower. The Swing Loan
Lender shall provide notice to the Agent of the making of any Swing Loans on a
weekly basis or as shall otherwise agreed between the Swing Loan Lender and
Agent.

                 (c) Participation by Lenders. Upon demand made to all of the
Lenders by the Swing Loan Lender, which demand may be made before or after a
Default or Event of Default and before or after the maturity date of the subject
Swing Loans, but subject to the provisions of paragraph (e) below, each Lender
(other than the Swing Loan Lender) shall promptly, irrevocably and
unconditionally purchase from the Swing Loan Lender, without recourse or
warranty, an undivided interest and participation in the Swing Loans then
outstanding. (A copy of any such demand shall be given by the Swing Loan Lender
to the Agent.) Each Lender shall effect such purchase by paying to the Swing
Loan Lender, without reduction or deduction of any kind, including reductions or
deductions for set-off, recoupment or counterclaim, in Dollars immediately
available to the Swing Loan Lender, an amount equal to such Lender's pro rata
share of the principal amount of all Swing Loans then outstanding. Each Lender's
pro rata share of the Swing Loans shall be based on the amount of such Lender's
pro

                                     -24-
<PAGE>
 
rata share of the total Commitment. Thereafter, the Lenders' respective
interests in such Swing Loans, and the remaining interest of the Swing Loan
Lender in such Swing Loans, shall in all respects be treated as RC Loans under
this Agreement, and subject to Section 2.5.6 (Default Rate) such Swing Loans
shall, after conversion, bear interest at the Base Rate plus Applicable Margin.
If any Lender does not pay any amount which it is required to pay promptly upon
the Swing Loan Lender's demand therefor, (i) the Swing Loan Lender shall be
entitled to recover such amount on demand from such Lender, together with
interest thereon, at the Federal Funds Rate for the first three Business Days,
and thereafter at the Base Rate, for each day from the date of such demand, if
made prior to 2: 00 p.m. (Philadelphia, Pennsylvania time) on any Business Day,
or, if made at any later time, from the next Business Day following the date of
such demand, until the date such amount is paid in full to the Swing Loan Lender
by such Lender and (ii) the Swing Loan Lender shall be entitled to all interest
payable by the Borrower on such amount until the date on which such amount is
received by the Swing Loan Lender from such Lender. Without limiting any
obligations of any Lender pursuant to this paragraph (c), if such Lender does
not pay such corresponding amount promptly upon the Swing Loan Lender's demand
therefor, the Swing Loan Lender shall notify the Borrower, who shall promptly
repay such corresponding amount to the Swing Loan Lender together with accrued
interest thereon at the applicable rate on such Swing Loans.

                 (d) No Set-off, Etc. Subject only to the limitations set forth
in the following paragraph (e), the obligations of each Lender to make available
to the Swing Loan Lender the amounts set forth in the preceding paragraph (c)
shall be absolute, unconditional and irrevocable under any and all circumstances
without reduction for any set-off or counterclaim of any nature whatsoever and
may not be terminated, suspended or delayed for any reason whatsoever, shall not
be subject to qualification or exception and shall be made in accordance with
the terms of this Agreement.

                 (e) Certain Limitations. No Lender shall be obligated to
purchase a participation in any Swing Loan if (A) the Swing Loan Lender did not
in good faith believe that the conditions specified in Section 4.2 were
satisfied at the time such Swing Loan was made (unless such condition was waived
in accordance with the terms of this Agreement) or (B) such Lender had notified
the Swing Loan Lender in a writing received by the Swing Loan Lender at least
one Business Day prior to the time that it made such Swing Loan that the Swing
Loan Lender was not authorized to make such Swing Loan and stating with
specificity the reason therefor. Further, no Lender shall be obligated to
purchase any principal amount of the Swing Loan which, when added to the
outstanding principal amount of the RC Loans made by such Lender, would exceed
such Lender's Commitment.

                 (f) Relationship with Cash Management. The Swing Loan Lender
may terminate its commitment to make Swing Loans at any time that such Swing
Loan Lender no longer provides cash management services to the Borrower by
providing 15 Business Days prior written notice to the Agent and the Borrower.
Upon receipt of such notice the Agent and Borrower may designate an other
consenting Lender (which may but need not be the Agent) to be the replacement
Swing Loan Lender. If no such replacement Swing Loan Lender is so designated
(with its consent) the provisions of Section 2.1.1(b) above (Swing Loans) and
related

                                     -25-
<PAGE>
 
provisions, as applicable, shall terminate and no Lender shall be obligated to
provide Swing Loans to the Borrower. If a replacement Swing Loan Lender is
designated as set forth above and consents to such appointment, such Lender
shall thereafter be the Swing Loan Lender for all purposes hereunder.

     2.5   Interest
           --------

           2.5.1 Interest Rate Options. The RC Loans shall bear interest, at the
                 ---------------------
Borrower's option (subject to the limitations and conditions set forth herein),
at (a) the Base Rate plus Applicable Margin or (b) the LIBOR Rate plus
Applicable Margin.

           2.5.2 Calculation and Payment of Interest. Interest on Base Rate
                 -----------------------------------
Loans (other than Swing Loans) shall be payable quarterly on each Quarterly
Payment Date, beginning with the first Quarterly Payment Date after the Closing
Date. Interest on LIBOR Loans shall be payable on the last day of each Interest
Period, provided that if the applicable Interest Period is six (6) months,
        --------
interest shall be payable on the ninetieth (90th) day of the Interest Period and
on the last day of the Interest Period. In addition to the foregoing, interest
on all LIBOR Loans shall be due and payable upon repayment or prepayment of such
Loans. Interest on all LIBOR Loans shall be computed on the basis of a 360 day
year, and interest on all Base Rate Loans shall be computed on the basis of a
365/366 day year unless the Base Rate is based on the Federal Funds Rate, in
which case it shall be computed on the basis of a 360 day year.

           2.5.3 Applicable Margin. The term "Applicable Margin" when used
                 -----------------            -----------------
herein with respect to the rate of interest to be charged on Loans shall mean,
at any time, the respective percentage set forth below under the caption for the
specified kind of Loan opposite the applicable Total Funded Debt/EBITDA Ratio
and the rate used to determine the amount of the Commitment Fees (the
"Commitment Fee Rate") shall be the rate set forth below under the caption
 -------------------
Commitment Fee Rate opposite the applicable Total Funded Debt/EBITDA Ratio:

     less than 2.25 to 1                0.000%            0.775%   0.150%

For purposes of determining the Applicable Margin or the amount of the
Commitment Fee Rate, the Total Funded Debt/EBITDA Ratio shall be determined
initially on the basis of the certificate provided for in Subsection 4.1.5 and
subsequently on the basis of the most recent Officer's Compliance Certificate
delivered pursuant to Subsection 6.1.4 below or pursuant to the following
paragraph of this Subsection 2.5.3. Any change in the Applicable Margin or
Commitment Fee Rate as a result of a change in the Total Funded Debt/EBITDA
Ratio shall be effective as of the first Business Day of the calendar month
following the date on which the Officer's Compliance Certificate delivered
pursuant to Subsection 6.1.4 below or the following paragraph of this Subsection
2.5.3 that indicates such change in the Total Funded Debt/EBITDA Ratio is
delivered to the Agent provided, however, if the financial statements or such
                       --------
Officer's Compliance Certificate are not delivered at the time specified in
Section 6.1 below or in the following paragraph, then the Applicable Margin for
any given kind of Loan and the Commitment Fee Rate shall, in the event that said
statements and Officer's Compliance Certificate are not delivered by the first
day of the calendar month following the date on which such statements or
Certificate is due, be the highest rate set forth above for such kind of Loan or
for the Commitment Fee Rate during any period that the Borrower is delinquent in
the delivery of such financial statements.

           On any date that the Borrower incurs Indebtedness to make any
Acquisitions (an "Acquisition-Margin Adjustment Date") the Borrower shall
                  ----------------------------------
deliver to the Agent an Officer's Compliance Certificate setting forth the pro
forma Total Funded Debt/EBITDA Ratio as of such date after giving effect to such
Indebtedness for Acquisitions. For purposes of such Officer's Compliance
Certificate, the amount of the EBITDA shall be the amount of EBITDA set forth on
the most recent Officer's Compliance Certificate (adjusted to give pro forma
effect to the Acquisition in the manner permitted by Section 1.2.3) and the
amount of Total Funded Debt shall be the amount of Total Funded Debt as at the
date of the incurrence of such Indebtedness for Acquisitions after giving effect
thereto.

           2.5.4 Manner of Election of Interest Rate and Interest Period. Unless
                 -------------------------------------------------------
otherwise elected by the Borrower, the Loans shall bear interest at the Base
Rate plus Applicable Margin. The Borrower may, upon three (3) Business Days'
prior written notice to the Agent in substantially the form of Exhibit C to this
                                                               ---------
Agreement (or such other form as the Agent and the Borrower may agree upon), and
subject to and upon the terms and conditions set forth in this Agreement, elect
to borrow money as, or convert outstanding RC Loans to, LIBOR Loans. Any such
election may be made with respect to a principal amount designated in such
notice equal to at least Two Million Dollars ($2,000,000.00) and integral
multiples of Five Hundred Thousand Dollars ($500,000.00) in excess of such
minimum, for an Interest Period designated by the Borrower in its notice.

           2.5.5 Certain Limitations. The right of the Borrower to elect a
                 -------------------
certain Type of Loan shall be limited as follows:

                 (a) The Borrower may not convert any Loan to a LIBOR Loan if at
the time of such conversion or election there shall exist a Default or an Event
of Default.

                 (b) If a LIBOR Rate is elected, such interest rate shall remain
in effect for the Interest Period selected and such interest rate shall not
otherwise be converted to another interest rate prior to the expiration of the
Interest Period except as otherwise required by this Agreement.

                 (c) LIBOR Loans shall, commencing on the last day of the
applicable Interest Period, bear interest at the Base Rate plus the Applicable
Margin unless prior thereto the Agent shall have received a timely notice
pursuant to this Section 2.5 that an elective rate based on the LIBOR Rate plus
Applicable Margin shall be effective commencing on such date with respect to any
or all of such principal.

                 (d) The Borrower may not elect a LIBOR Rate for any Interest
Period if the effect of such election, (as could reasonably be determined by the
Borrower at the time of such election) would be to require the Borrower to make
a repayment or prepayment of a LIBOR Loan prior to the end of the relevant
Interest Period. Without limiting the generality of the foregoing, no Interest
Period may be elected for Loans that would end later than the Maturity Date.

                 (e) The Borrower may not elect a LIBOR Rate if such election
would require the Agent to administer concurrently more than five (5) Types of
LIBOR Loans.

           2.5.6 Default Rate. Anything in this Agreement to the contrary
                 ------------
notwithstanding, during the existence of any Event of Default hereunder, the
Loans shall bear interest at a rate equal to the sum of two percent (2%) per
annum plus the interest rate(s) otherwise in effect hereunder (the "Default
      ----                                                          -------

           2.6.1 Mandatory Suspension and Conversion of LIBOR Loans. Each
                 --------------------------------------------------
Lender's obligations to make, continue or convert into LIBOR Loans (or, as
applicable, LIBOR Loans with a certain Interest Period) shall be suspended, and
all such Lender's outstanding Loans of such Type shall be converted into Base
Rate Loans on the last day of their applicable Interest Periods (or, if earlier,
in the case of clause (c) below, on the last day such Lender may lawfully
continue to maintain Loans of such Type or, in the case of clause (d) below, on
the day determined by such Lender to be the last Business Day before the
effective date of the applicable restriction), and all pending requests for the
making or continuation of or conversion into Loans of such Type by such Lender
shall be deemed requests for Base Rate Loans, if:

                 (a) on or prior to the determination of an interest rate for a
LIBOR Loan for any Interest Period, the Agent determines that for any reason
appropriate information is not available to it for purposes of determining the
LIBOR Rate for such Interest Period;

                 (b) such Lender determines that the LIBOR Rate as determined by
the Agent for such Interest Period would not accurately reflect the cost to any
Lender of making, continuing or converting into a LIBOR Loan for such Interest
Period;

                 (c) at any time, such Lender determines that any Regulatory
Change makes it unlawful or impracticable for any Lenders to make, continue or
convert into a LIBOR Loan or a LIBOR Loan of a certain Interest Period, or to
comply with its obligations hereunder in respect thereof; or

                 (d) such Lender determines that, by reason of any Regulatory
Change, such Lender is restricted, directly or indirectly, in the amount that it
may hold of (i) a category of liabilities that includes deposits by reference to
which, or on the basis of which, the interest rate applicable to LIBOR Loans of
such Type is directly or indirectly determined or (ii) the category of assets
that includes LIBOR Loans of such Type.

If, as a result of this Subsection 2.6.1, any Loan of any Lender that would
otherwise be made or maintained as or converted into a LIBOR Loan for any
Interest Period is instead made or maintained as or converted into a Base Rate
Loan, then, unless the corresponding Loan of each of the other Lenders is also
to be made or maintained as or converted into a Base Rate Loan, such Loan shall
be treated as being a LIBOR Loan for such Interest Period for all purposes of
this Agreement (including the timing, application and proration among the
Lenders of interest payments, conversions and prepayments) except for the
calculation of the interest rate borne by such Loan. The Agent shall promptly
notify the Borrower and each Lender of the existence or occurrence of any
condition or circumstance specified clause (a) above, and each Lender shall
promptly notify the Borrower and the Agent of the existence, occurrence or
termination of any condition or circumstance specified in clause (b), (c) or (d)
above applicable to such Lender's Loans, but the failure by the Agent or such
Lender to give any such notice shall not affect such Lender's rights hereunder.
The Agent and the Lenders shall only cause the suspension of LIBOR Rate lending
under this Subsection 2.6.1 if such suspension is made pursuant to a policy
adopted by the Agent or such Lender, as the case may be, to suspend such LIBOR
Rate lending generally from

                                     -29-
<PAGE>
 
customers similar to the Borrower and having similar provisions in agreements
with such Agent or Lender.

           2.6.2 Regulatory Changes; Increased Costs. If in the determination of
                 -----------------------------------
any Lender (a) any Regulatory Change shall directly or indirectly (i) reduce the
amount of any sum received or receivable by such Lender on any Loan, (ii) impose
a cost on such Lender or any Affiliate of such Lender that is attributable to
the making or maintaining of, or such Lender's commitment to make, any Loan,
(iii) require such Lender or any Affiliate of the Lender to make any payment on,
or calculated by reference to, the gross amount of any amount received by the
Lender under any Loan Document or (iv) reduce, or have the effect of reducing,
the rate of return on any capital of the Lender or any Affiliate of the Lender
that the Lender or such Affiliate is required to maintain on account of any Loan
or the Lender's commitment to make any Loan and (b) such reduction, increased
cost or payment shall not be fully compensated for by an adjustment in the
applicable rates of interest payable under the Loan Documents, then, upon
written request of such Lender, the Borrower shall pay to such Lender such
additional amounts as the Lender determines will, together with any adjustment
in the applicable rates of interest payable hereunder, fully compensate it for
such reduction, increased cost or payment. Such additional amounts shall be
payable, in the case of those applicable to prior periods, within 15 Business
Days after request by the Lender for such payment and, in the case of those
applicable to future periods, on the date specified in such request. The Lender
will promptly notify the Borrower of any determination made by it referred to
above, but the failure to give such notice shall not affect the Lender's right
to such compensation; provided, however, that the Borrower shall not be required
                      --------  -------
to pay such additional amounts for any period ending prior to the date that is
one year prior to the giving of such notice.

           2.6.3 Capital Requirements. If, in the determination of any Lender,
                 --------------------
such Lender or any Affiliate of such Lender is required, as a result of a
Regulatory Change, to maintain capital on account of any Loan or such Lender's
commitment to make any Loan, then, upon request by such Lender, the Borrower
shall from time to time thereafter pay to such Lender such additional amounts as
such Lender determines will fully compensate for any reduction in the rate of
return on the capital that such Lender or such Affiliate is so required to
maintain on account of such Loan or commitment suffered as a result of such
capital requirement. Such additional amounts shall be payable, in the case of
those applicable to prior periods, within 15 Business Days after request by such
Lender for such payment and, in the case of those relating to future periods, on
the dates specified in such request; provided, however, that the Borrower shall
                                     --------  -------
not be required to pay such additional amounts for any period ending prior to
the date that is one year prior to the giving of such notice.

           2.6.4 Breakage. The Borrower shall pay to each Lender, from time to
                 --------
time, upon request, the Breakage Amounts (as hereinafter defined) to compensate
it for any loss, cost or expense, including, without limitation, loss of the
Applicable Margin incurred by it as a result of (a) any payment, prepayment
(whether voluntary, mandatory or scheduled) or conversion of a LIBOR Loan on a
date other than the last day of an Interest Period for such LIBOR Loan or (b) a
LIBOR Loan for any reason not being made or converted, or any payment of
principal thereof or 

                                     -30-
<PAGE>
 
interest thereof not being made, on the date therefor determined in accordance
with the applicable provisions of this Agreement. "Breakage Amount" means, with
                                                   ---------------
respect to any LIBOR Loan, an amount equal to the difference between (A) and (B)
where


           (A)   is an amount equal to the outstanding principal amount of
                 the subject Loan multiplied by the LIBOR Rate plus
                                  ----------
                 Applicable Margin relating to such Loan for the period
                 commencing on the date that such LIBOR Loan is prepaid or
                 failed to be made (the "Breakage Determination Date") and
                                         ---------------------------
                 ending on the last day of the applicable Interest Period
                 and
                 
           (B)   is an amount equal to the outstanding principal amount of
                 the subject Loan multiplied by the quotient of (i) the
                                  ----------
                 rate of interest per annum (rounded upwards if necessary
                 to the nearest one-sixteenth of one percent) equal to the
                 rate at which dollar deposits for an interest period
                 commencing on the Breakage Determination Date and ending
                 on the last day of the Interest Period referred to in
                 clause (A) above are offered based on information
                 presented on Telerate Page 3750 (or any successor thereto)
                 at 11:00 a.m. (London time) two (2) Eurodollar Business
                 Days prior to the commencement of the relevant period, or
                 if such information is unavailable, then the rate of
                 interest per annum (rounded upwards if necessary to the
                 nearest one-sixteenth of one percent) at which deposits of
                 U.S. Dollars for periods equal to such period and in
                 amounts substantially similar to such amount are available
                 to the Agent or relevant Lender, as the case may be, from
                 prime banks in the London Interbank Eurocurrency Market on
                 or about 11:00 a.m. London time two (2) Eurodollar
                 Business Days prior to the first day of the relevant
                 Interest Period, divided by (ii) a number equal to 1.00
                                  ----------
                 minus the LIBOR Reserve Percentage for the relevant
                 period.

           2.6.5 Determinations. In making the determinations contemplated by
                 --------------
this Section 2.6, the relevant Lender may make such estimates, assumptions,
allocations and the like that such Lender in good faith determines to be
appropriate, and the Lender's selection thereof in accordance with this Section
2.6, and the determinations made by the Lender on the basis thereof, shall be
final, binding and conclusive upon the Borrower, absent manifest error. Each
Lender shall furnish to the Borrower, at the time of any request for
compensation under Subsections 2.6.2 or 2.6.3 upon request, a certificate
outlining in reasonable detail the computation of any amounts claimed by it
under said Subsection 2.6.2 or 2.6.3 and the assumptions underlying such
computations, which shall include a statement of an officer of such Lender
certifying that such request for compensation is being made pursuant to a policy
adopted by such Lender to seek such compensation generally from customers
similar to the Borrower and having similar provisions in agreements with such
Lender.

           2.6.6 Change of Lending Office. If an event occurs with respect to a
                 ------------------------
Lending Office of any Lender that makes operable the provisions of Subsection
2.6.1 or requires a 

                                     -31-
<PAGE>
 
payment under Subsection 2.6.2 or 2.6.3, such Lender shall, if requested by the
Borrower, use reasonable efforts to designate another Lending Office, the
designation of which will reduce the amount the Borrower is so obligated to pay,
eliminate such operability or reduce the amount such Lender is so entitled to
claim, provided, however, that such designation would not, in the sole and
       --------
absolute discretion of such Lender, be disadvantageous to such Lender in any
manner or contrary to such Lender's policies. Except as set forth in this
Subsection 2.6.6, any Lender may designate any lending office as its Lending
Office for each Type of Loan.

           2.6.7  Flexibility Respecting Source of Funds. Although each Lender
                  --------------------------------------
may elect to purchase in the London Inter-Bank Eurocurrency Market one or more
Eurodollar deposits in order to fund or maintain its funding of its pro rata
share of the principal amount of the LIBOR Loans during the Interest Period in
question, it is acknowledged that the provisions of this Agreement relating to
such funding are included only for the purpose of determining the rate of
interest to be paid and any other amounts owing under this Agreement in
connection with such election, and each Lender shall be entitled to fund and
maintain its funding of all or any part of that portion of the principal amount
of the Loans in any manner it sees fit, but all such determinations shall be
made as if each Lender had actually funded and maintained such LIBOR Loans
through the purchase of Eurodollar deposits in an amount equal to the principal
amount of such LIBOR Loans having a maturity corresponding to such Interest
Period.

           2.6.8  Replacement of Lender. If any Lender requests compensation
                  ---------------------
pursuant to Subsection 2.6.2 (Regulatory Changes; Increased Costs) or 2.6.3
(Capital Requirements), or such Lender's obligation to make or continue, or to
convert Loans into LIBOR Loan shall be suspended pursuant to Subsection 2.6.1
(Mandatory Suspension and Conversion of LIBOR Loans) (other than clause (a) of
Subsection 2.6.1), or such Lender requests compensation pursuant to Section 2.9
(Taxes), the Borrower, upon three Business Days' notice, may require that such
Lender transfer all of its right, title and interest under this Agreement, such
Lender's Notes and the other Loan Documents to any Eligible Institution
identified by the Borrower with the consent of the Agent, subject to the
following: (a) such proposed transferee shall agree to assume all of the
obligations of such Lender for consideration equal to the outstanding principal
amount of such Lender's Loans, together with interest thereon to the date of
such transfer, and satisfactory arrangements are made for payment to such Lender
of all other amounts payable hereunder to such Lender on or prior to the date of
such transfer (including any fees accrued hereunder and any amounts that would
be payable under Section 2.6.4 (Breakage)as if all of such Lender's Loans were
being prepaid in full on such date) and (b) if such Lender being replaced has
requested compensation pursuant to Subsection 2.6.2 or 2.6.3 or Section 2.9,
such proposed transferee's aggregate requested compensation, if any, pursuant to
Subsection 2.6.2 or 2.6.3 or Section 2.9 with respect to such replaced Lender's
Loans is lower than that of the Lender replaced. Without prejudice to the
survival of any other agreement of the Borrower hereunder, the agreements of the
Borrower contained in this Section 2.6 and in Section 12.14 (Payment and
Reimbursement of Costs and Expenses; Indemnification)(without duplication of any
payments made to such Lender by the Borrower or the proposed transferee) shall
survive for the benefit of any Lender replaced under this Subsection 2.6.8 with
respect to the time prior to such replacement.

     2.7   Commitment Fees. The Borrower shall pay to the Agent for the
           ---------------
account of the Lenders (based on their proportionate share of the Commitment)
quarterly on each Quarterly Payment Date and at any time there shall be a
reduction in the amount of the Commitment and on the Maturity Date, a
non-refundable commitment fee (the "Commitment Fee") (calculated on the basis of
                                    --------------
a 365/366 day year for the actual days elapsed) equal to the product of the
Commitment Fee Rate times the Commitment Fee Base during the period ended on
such Quarterly Payment Date or such Commitment reduction date or Maturity Date,
as the case may be.

     2.8   Payments to the Agent.
           ---------------------

           2.8.1  Method of Payment. All payments on account of principal and
                  -----------------
interest on the RC Loans, the Commitment Fees, and all other amounts otherwise
payable by the Borrower to the Agent or to the Lenders under this Agreement
(other than payments in respect of Swing Loans), shall be made to the Agent in
U.S. Dollars which are immediately available by noon, (Philadelphia,
Pennsylvania time), on the due date for such payment, at Agent's principal
office (which as of the date hereof is at 1339 Chestnut Street, Philadelphia, PA
19101) specifying amount and date of payment, re: Specialty Products &
Insulation Co. (and if by wire transfer, in accordance with the instructions on
the signature page to this Agreement executed by First Union National Bank), or
to such other accounts or Persons or at such other place as the Agent may direct
in writing. Payments made by the Borrower to the Agent for the benefit of any
Lender (other than the Swing Loan Lender) shall fulfill Borrower's obligations
to make such payments to the Lender hereunder. The Borrower hereby authorizes
the Lenders (after receipt of notice from the Agent to do so) to (i) apply to
the aforesaid payments, up to the amount of such payments, any portion of the
balance of any account maintained by the Borrower for the purpose of
facilitating said payments, and/or (ii) cause the aforesaid payments to be made,
if not paid by the Borrower when due, by drawing under the loan facilities
provided under this Agreement if available; notwithstanding the foregoing, any
amounts not paid when due shall bear interest at the Default Rate, subject to
the following sentence. The failure by the Borrower to make a payment by noon
shall not constitute an Event of Default if such payment is made on the due
date; however, any payment made after such time on such due date shall be deemed
made on the next Business Day for the purpose of interest and reimbursement
calculations.

           2.8.2  Pro Rata Application. Except with respect to Swing Loans and 
                  --------------------
as otherwise set forth in this Agreement, payments made to the Agent for the
account of the Lenders shall be deemed to be made to the Lenders in proportion
to their respective shares of the applicable amount due. The Agent shall
promptly remit to each Lender its pro rata share of such payment in immediately
available funds, except that all reimbursement payments in respect of losses,
out-of-pocket expenses, funding losses or like matters shall be retained by the
Agent or remitted to the Lenders according to their respective appropriate
entitlement to such reimbursement and all amounts payable to the Agent as
reimbursement of costs or expenses or otherwise payable hereunder may be
deducted before making any payments to the Lenders. The Agent shall incur no
liability for allocations which it reasonably determines to be made in
accordance with the terms of this Agreement, absent gross negligence or willful
misconduct as determined by a court of competent jurisdiction.

           2.8.3  Permitted Assumptions by Agent. Unless the Agent shall have
                  ------------------------------
been notified by the Borrower in writing prior to the date on which the Borrower
is scheduled to make a payment to the Agent for the account of one or more of
the Lenders (such payment being the "Borrower Required Payment"), which notice
                                     -------------------------
shall be effective upon receipt, that the Borrower does not intend to make the
Borrower Required Payment to the Agent, the Agent may assume that the Borrower
Required Payment has been made and may, in reliance upon such assumption (but
shall not be required to), make such amount available to the Lenders entitled
thereto on such date. If the Borrower has not in fact made the Borrower Required
Payment to the Agent, the recipient(s) of such payment shall, on demand, repay
to the Agent the amount so made available together with interest in respect of
each day during 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 day (as determined by the
Agent) provided, however, that if such Lender shall fail to repay to the Agent
       --------
the amount so made available within two (2) Business Days after the date it
shall have received notice from the Agent that the original demand for payment
was not satisfied, interest shall accrue (from such second Business Day after
notice is received) at a rate equal to the rate payable by the Borrower on the
corresponding Loan (but not the Default Rate).

     2.9   Taxes.
           -----

           2.9.1  Taxes Payable by the Borrower. If any Tax is required to be
                  -----------------------------
withheld or deducted from, or is otherwise payable by the Borrower in connection
with, any payment due hereunder to any Lender or the Agent that is not a "United
                                                                          ------
States Person" (as such term is defined in Section 7701(a)(30) of the Code) the
- -------------
Borrower (i) shall, if required, withhold or deduct the amount of such Tax from
such payment and, in any case, pay such Tax to the appropriate taxing authority
in accordance with applicable law and (ii) except in the case of any Bank Tax,
shall pay to such Lender or the Agent such additional amounts as may be
necessary so that the net amount received by such Lender or the Agent with
respect to such payment, after withholding or deducting all Taxes (other than
Bank Taxes) required to be withheld or deducted, is equal to the full amount
payable hereunder. If any Tax is withheld or deducted from, or is otherwise
payable by the Borrower in connection with, any payment due to any such Lender
or the Agent hereunder, the Borrower shall furnish to such Lender or the Agent
the original or a certified copy of a receipt for such Tax from the applicable
taxing authority within 30 days after the date of such payment (or, if such
receipt shall not have been made available by such taxing authority within such
time, the Borrower shall use reasonable efforts to promptly obtain and furnish
such receipt). If the Borrower fails to pay any Taxes, other than Bank Taxes,
when due to the appropriate taxing authority or fails to remit to any such
Lender or the Agent the required receipts, the Borrower shall indemnify such
Lender or the Agent for any such Taxes, interest, penalties or additions to such
Tax that may become payable by such Lender or the Agent as a result of any such
failure.

           2.9.2  Reimbursement of Taxes Payable by any Lender or the Agent. The
                  ---------------------------------------------------------
Borrower shall, promptly upon request by any Lender or the Agent for the payment
thereof, pay to any such Lender or the Agent an amount equal to (a) all Taxes
(other than Bank Taxes and without duplication of amounts paid pursuant to the
preceding Subsection 2.9.1) payable by such 


                                     -34-
<PAGE>
 
Lender or the Agent with respect to any payment due to such Lender or the Agent
hereunder and (b) all Taxes (other than Bank Taxes) payable by such Lender or
the Agent as a result of payments made by the Borrower (whether made to a taxing
authority or to such Lender or the Agent) pursuant to Subsection 2.9.1 or this
Subsection 2.9.2. The Agent and the Lenders shall only require payment under
this Subsection 2.9.2 if such request for payment is made pursuant to a policy
adopted by the Agent or such Lender, as the case may be, to seek such payments
generally from customers similar to the Borrower and having similar provisions
in agreements with such Agent or Lender.

           2.9.3  Exemption from U.S. Withholding Taxes.
                  -------------------------------------

                  (a) Each Lender that is not a United States Person shall
submit to the Borrower and the Agent, on or before the fifth day prior to the
first Quarterly Payment Date occurring after the Closing Date (or, in the case
of a Person that is not a United States Person and that became a Lender by
assignment, promptly upon such assignment), two duly completed and signed copies
of either (i) a Form 1001 of the United States Internal Revenue Service
entitling such Lender to a complete exemption from withholding on all amounts to
be received by such Lender pursuant to this Agreement and the Loans or a Form
4224 of the United States Internal Revenue Service relating to all amounts to be
received by such Lender pursuant to this Agreement and the Loans or (ii) in the
case of any Lender (or Person that becomes a Lender by assignment) that is
exempt from United States Federal withholding tax pursuant to Sections 871(b) or
881(c) of the Code, Form W-8 of the United States Internal Revenue Service. Each
such Lender shall, from time to time after submitting any such Form, submit to
the Borrower and the Agent such additional duly completed and signed copies of
one or another such Forms (or any successor forms as shall be adopted from time
to time by the relevant United States taxing authorities) as may be (x)
requested in writing by the Borrower or the Agent and (y) appropriate under the
circumstances and under then current United States law or regulations to avoid
or reduce United States withholding taxes on payments in respect of all amounts
to be received by such Lender pursuant to this Agreement or the Loans. Upon the
request of the Borrower or the Agent, each Lender that is a United States Person
shall submit to the Borrower and the Agent a certificate to the effect that it
is a United States Person.

                  (b) If any Lender determines that it is unable to submit to
the Borrower or the Agent any form or certificate that such Lender is obligated
to submit pursuant to the preceding paragraph, or that it is required to
withdraw or cancel any such form or certificate, or that any such form or
certificate previously submitted has otherwise become ineffective or inaccurate,
such Lender shall promptly notify the Borrower and the Agent of such fact.

                  (c) Notwithstanding anything to the contrary contained herein,
the Borrower shall not be required to pay any additional amount in respect of
United States withholding taxes pursuant to Subsection 2.9.1 above to any Lender
that (i) is not, on the date this Agreement is first executed by such Lender
(or, in the case of a Person that became a Lender by assignment, on the date of
such assignment), either (x) entitled to submit Form W-8 or Form 1001 of the
United States Internal Revenue Service (or any successor form as shall be
adopted from time to time by the relevant United States taxing authorities)
entitling such Lender to a


                                     -35-
<PAGE>
 
complete exemption from withholding on all amounts to be received by such Lender
pursuant to this Agreement and the Loans or Form 4224 of the United States
Internal Revenue Service (or any successor form as shall be adopted from time to
time by the relevant United States taxing authorities) relating to all amounts
to be received by such Lender pursuant to this Agreement and the Loans or (y) a
United States Person, (ii) is no longer entitled or, in the case of a Lender
that is no longer a United States Person, is not entitled, to submit either such
Form (or any successor form as shall be adopted from time to time by the
relevant United States taxing authorities) as a result of any change in
circumstances or other event other than a Regulatory Change or (iii) with
respect to any affected interest payments, fails to fulfill its requirements set
forth in this Section 2.9 (other than as a result of a Regulatory Change).

accelerated maturity thereof or upon any mandatory or prepayment or otherwise)
any of the Obligations, the Subsidiary Guarantors will promptly pay the same,
without any demand or notice whatsoever. This guaranty is a guaranty of payment

Code of 1978, as amended, minus (y) $1.00 (one U.S. Dollar).

or any change in the time, manner or place of payment of the Obligations;

                  (c) any amendment or modification of or supplement to any Loan
Document, or any furnishing or acceptance of any security, or any release of any
security or the release of any Person's obligations (including without
limitation, any Subsidiary Guarantor or the Borrower) with respect to the

                  (i) any other occurrence whatsoever, whether similar or
dissimilar to the foregoing.

     3.3   Continuing Guaranty. This guaranty and suretyship is an absolute,
           -------------------
unconditional, present and continuing guaranty and suretyship of payment and is
in no way conditional or contingent; it shall remain in full force and effect
until terminated pursuant to Section 3.7 below.

     3.4   Joint and Several Liability. Each and every representation, warranty,
           ---------------------------
covenant and agreement made by the Subsidiary Guarantors, or any of them, under

the Subsidiary Guarantors, whether or not so expressly stated herein.

     3.5   Waivers.
           -------

           3.5.1  In General. Each Subsidiary Guarantor hereby waives, to the

its liability under this Agreement. Without limiting the foregoing, neither the
Lenders nor the Agent shall be required to make any demand upon, or to pursue or
exhaust any rights or remedies against the Borrower, any other Subsidiary
Guarantor or any other Person. No failure on the part of the Agent or any Lender
to exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder
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.

           3.5.2  Subrogation. Each Subsidiary Guarantor hereby agrees that it
                  -----------
will not enforce or otherwise exercise or claim or assert any rights of
subrogation or contribution against any Person with respect to the Obligations
or any security therefor unless and until all the Obligations are indefeasibly
paid in full.

     3.6   Additional Subsidiary Guarantors. Subsidiary Guarantors shall at all

           3.7.1  Termination of Guaranty In General. At such time as (a) the
                  ----------------------------------
Lenders have no obligations to make further fundings to the Borrower under the
terms of this Agreement and (b) all the Obligations have been indefeasibly paid

terminate, provided, however, that (i) all indemnities of the Subsidiary
           --------
Guarantors or the Borrower contained in this Agreement or any Loan Document
shall survive and remain operative and in full force and effect regardless of
the termination of any other provisions of this Agreement and (ii) the guaranty
provided for in this Article 3 shall be reinstated if at any time any payment of
any of the Obligations is rescinded or must otherwise be returned by the Agent
or any Lender upon the insolvency, bankruptcy or reorganization of the Borrower
or any Subsidiary Guarantor or otherwise, all as though such payment had not
been made.

obligations of that Sold Subsidiary Guarantor hereunder shall terminate.
However, all the obligations of the other Subsidiary Guarantors hereunder shall
remain in full force and effect. Each Lender hereby authorizes and directs the
Agent to execute such release agreements and other documents and take such other
action as shall be necessary or desirable in the opinion of the Agent to carry
out the purposes of this Subsection 3.7.2.

provisions set forth in Article 10 below, the Agent (acting for the benefit of
itself and/or the Lenders) shall have the right to seek recourse against any one
or more of the Subsidiary Guarantors to the fullest extent provided herein. No
election to proceed in one form of action or proceeding or against any party, or
on any obligation, shall constitute a waiver of the Agent's right to proceed in
any other form of action or proceeding or against other parties. The Agent may
proceed to protect and enforce the guaranty provided in this Article 3 by suit
or suits or proceedings in equity, at law or in bankruptcy against any or all of
the Subsidiary Guarantors in one action or in as many different actions or
forums as the Agent shall determine.

           5.1.12 Compliance with Law. The Borrower, each of its Subsidiaries
                  -------------------
and all officers, directors and other agents acting on behalf of such Persons

           5.1.13 Absence of Default. There exists no Default or Event of
                  ------------------
Default.

           5.1.14 Financial Statements; Projections; Material Adverse Change.
                  -----------------------------------------------------------  

                  (a) All financial statements delivered pursuant to Subsection
4.1.11 above (Conditions/Financial Statements; Projections) have been prepared
in accordance with GAAP applied on a consistent basis throughout the period
specified and present fairly in all material respects the financial position of
the subject Persons. None of the Borrower or any of its Subsidiaries has on the
date hereof any material non-ordinary course of business, contingent
liabilities, liabilities for taxes (other than those not yet due and payable),
unusual forward or long-term commitments or unrealized or anticipated losses
from any unfavorable commitments, except as referred to or reflected or provided
for in said balance sheets (including the footnotes thereof) as at said dates.
Since the date of such financial statements no event or condition has occurred
which could result in a Material Adverse Effect. In any certificates delivered
to the Lenders or the Agent after the date of this Agreement which certify the
truth and accuracy of the representations, or at any time that these
representations shall be deemed restated, this representation shall be deemed to
apply to financial statements which the Borrower has most recently delivered to
the Lenders either pursuant to Subsection 6.1.2 (Quarterly Financial Statements)
or Subsection 6.1.3 (Annual Financial Statements), as the case may be, as of the
time of such certification.

                  (b) The operating models delivered pursuant to Subsection
4.1.11 (Conditions/Financial Statements; Models) above present fairly the
Borrower's reasonable assessment of the financial prospects of the Borrower and
its Subsidiaries for the periods covered thereby. To the knowledge of the
Borrower, the assumptions used in such models are reasonable. Given the
uncertainties inherent in the preparation of projections generally, the actual
financial results of the Borrower and its Subsidiaries for the period covered
thereby may be different than those set forth in the models.

           5.1.15 Taxes; Tax-Free Nature of Spin-Off. (a) The Borrower and its
                  ----------------------------------
Subsidiaries have filed all United States Federal income tax returns and all
other material Tax returns which are required to be filed by them and have paid
all Taxes due as set forth on such returns or pursuant to any assessment
received by the Borrower or any of its Affiliates and 



                                     -46-
<PAGE>
 
relating to the Borrower or its Subsidiaries, except such Taxes, if any, as are
being contested in good faith by appropriate proceedings, if any, and as to
which adequate reserves have been provided. The charges, accruals and reserves
on the books of the Borrower and its Subsidiaries in respect of Taxes and other
governmental charges are, in the opinion of the Borrower, adequate. There is
currently in effect no tax sharing, tax allocation or similar agreement to which
the Borrower or any of its Subsidiaries is a party other than the Tax Sharing
Agreement.

                  (b) As of the Closing Date, the assumptions and conditions set
forth in the Tax Opinion that supported the conclusion that the Spin-Off was tax
- -free are all true or have all been satisfied, as the case may be, (except such
conditions, if any, that are by the terms of the Tax Opinion, to occur after the
Closing Date). The Spin-Off was consummated without any tax liability resulting
therefrom. To the knowledge of the Borrower, (i) no action has been proposed by
the Internal Revenue Service that would result in, or threaten to result in, the
Spin-Off or any related transaction being treated other than as described in the
Tax Opinion and (ii) no facts or circumstances exist that would constitute
grounds for an amendment or modification of the conclusions set forth in such
Tax Opinion, including, without limitation, any such grounds described in 26 CFR
(S) 601.201(1) or Rev. Proc. 92-1, sec. 11 (or any superseding Revenue Procedure
or other Internal Revenue Service pronouncement).

           5.1.16 Indebtedness. Schedule 5.1.16 correctly describes as of the
                  ------------  ---------------
Closing Date all Indebtedness of the Borrower and its Subsidiaries outstanding
or for which any such Person has commitments specifying which such Indebtedness
is being repaid concurrent with the closing and which shall remain outstanding
after the closing. Neither the Borrower nor any of its Subsidiaries is in
default beyond any applicable grace period with respect to any Indebtedness or
any instrument or agreement relating to such Indebtedness.

           5.1.17 Federal Reserve Regulations. No Indebtedness that is required
                  ---------------------------

incurred for the purpose of purchasing or carrying any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System
(12 C.F.R. 221, as amended), and no proceeds of the Loans will be used to
purchase or acquire any such margin stock.

           5.1.18 Investment Company Act. Neither the Borrower nor any
                  ----------------------
Subsidiary thereof is an "investment company," or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

           5.1.19 Public Utility Holding Company Act. Neither the Borrower nor
                  ----------------------------------

"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," as such terms are defined in the Public Utility
Holding Company Act of 1935, as amended.

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

           Joinder of Additional Subsidiary Guarantors. Subject to Section 9.7
           -------------------------------------------
(respecting dispositions), the Borrower will take such action, and will cause

necessary to ensure that all 

                                     -57-
<PAGE>
 
Subsidiaries of the Borrower on the Closing Date are, and all entities that
become Subsidiaries of the Borrower after the Closing Date become, "Subsidiary
Guarantors" hereunder. Without limiting the generality of the foregoing, in the
event that the Borrower or any Subsidiary thereof shall form or acquire any new
Subsidiary after the date hereof, the Borrower or such Subsidiary, as the case
may be, will cause such new Subsidiary to become a "Subsidiary Guarantor"
hereunder pursuant to a Joinder substantially in the form of Exhibit N hereto
                                                             ---------

accordance with the provisions hereof and thereof, a "Joinder") pursuant to
                                                      -------
which such new Subsidiary shall agree to be bound by all provisions of this
Agreement and the other Loan Documents to the extent that such agreements
provide for rights and obligations of Persons designated as "Subsidiaries of the
Borrower", "Subsidiary Guarantors" or any similar term. Together with the
Joinder for each new Subsidiary, the Borrower or applicable Subsidiary shall
deliver such proof of corporate action, incumbency of officers, opinions of
counsel and other documents as the Agent shall reasonably request.

     8.10  Subsidiaries to be Wholly-Owned. Each of the Borrower and the
           -------------------------------
Subsidiaries thereof will take such action from time to time as shall be
necessary to ensure that each of its Subsidiaries is, directly or indirectly, a
wholly-owned Subsidiary of the Borrower. Without limiting the generality of the
foregoing, neither of the Borrower nor any of its Subsidiaries shall sell,
transfer or otherwise dispose of any shares of stock of any Subsidiary owned by
it, nor permit any such Subsidiary to issue any shares of stock of any class
whatsoever to any Person (other than to the Borrower or another Subsidiary of
the Borrower) if any of the foregoing actions would result in there being
Subsidiaries of the Borrower that are not wholly-owned by the Borrower.

     8.11  Maintenance of Certain Contracts and Other Rights. The Borrower
           -------------------------------------------------
and each Subsidiary thereof shall maintain, preserve, protect and, when

rights held by any of them and all agreements to which any of them are parties
including, without limitation, agreements with suppliers and with customers,
which are necessary or useful to conduct the Permitted Businesses except where
the failure to do so could not result in a Material Adverse Effect. The Borrower
shall maintain in full force and effect, subject to no modification or amendment
except as may be approved by the Requisite Lenders, the Irex Servicing Agreement
for at least two years and thereafter until Borrower can demonstrate to the
satisfaction of the Agent its ability to perform on its own behalf the services
provided by Irex pursuant to the Irex Servicing Agreement. The Borrower and its
Subsidiaries shall maintain in full force and effect, subject to no modification
or amendment except as may be approved by the Requisite Lenders (and except,
with respect to the Tax Sharing Agreement, modifications or amendments required
to add additional Subsidiaries acquired or created in compliance with the terms
of this Agreement, from time to time), the Spin-Off Documents, the Tax Sharing
Agreement and the Subordinated Debt Documents.

     8.12  Conduct of Business. The Borrower and each of its Subsidiaries
           -------------------
shall continue to operate, without interruption, Permitted Businesses. They
shall conduct no business other than Permitted Business.

unpaid principal balance of the Notes, and interest accrued and premium, if any,
thereon, and any unpaid accrued Commitment Fees and all other amounts payable
hereunder and under the other Loan Documents, shall be immediately due and
payable by the Borrower and the Commitment shall terminate. Such principal and
interest, premium and fees shall thereupon become and be immediately due and
payable without presentation, demand, protest, notice of protest or other notice
of dishonor of any kind, all of which are hereby expressly waived by the
Borrower. Upon the occurrence of any other Event of Default, or at any time
thereafter, if any Event of Default shall then be continuing, the Agent may (and
shall if directed by the Requisite Lenders pursuant to Section 11.6) by written
notice to the Borrower, declare the entire unpaid principal balance of the
Notes, and interest accrued and premium, if any, thereon and any unpaid accrued
Commitment Fees and all other amounts payable hereunder and under the other Loan
Documents, to be immediately due and payable by the Borrower and/or may
terminate the Commitment. Such principal and interest, premium, fees and other
amounts shall thereupon become and be immediately due and payable, without
presentation, demand, protest, notice of protest or other notice of dishonor or
other notice of any kind, all of which are hereby expressly waived by the
Borrower. In the event of any such acceleration, the Agent (acting directly or
through the appointment of one or more trustees or agents of Agent's choosing)
may proceed to protect and enforce its rights and those of the Lenders under the
Loan Documents in any manner or order it or they deem expedient without regard
to any equitable principles of marshalling or otherwise.

           10.2.2 Equitable Remedies. It is agreed that, in addition to all
                  ------------------
other rights hereunder or under law, the Agent shall have the right to institute
proceedings in equity for the

<PAGE>
 
specific performance of any covenant or agreement made in any of the Loan
Documents or for an injunction against the violation of any of the terms of any
of the Loan Documents or in aid of the exercise of any power granted in any of
the Loan Documents or by law or otherwise.

           10.2.3 Remedies Cumulative. All rights and remedies given by this
                  -------------------
Agreement, the Notes and the other Loan Documents are cumulative and not
exclusive of any of such rights or remedies or of any other rights or remedies
available to the Agent or any Lender, and no course of dealing between the
Borrower and/or any Subsidiary thereof, on the one hand, and the Agent or any
Lender, on the other hand, or any delay or omission in exercising any right or
remedy shall operate as a waiver of any right or remedy, and every right and
remedy may be exercised from time to time and as often as shall be deemed
appropriate by the Agent or any Lender.

     11.1  Authority.
           ---------

           The Lenders hereby irrevocably appoint First Union National Bank to
act as Agent as specified in the Loan Documents, and each of the Lenders hereby
irrevocably authorizes, and each of the holders of any Note by the acceptance of
such Note shall be deemed irrevocably to authorize First Union National Bank,
for such Lender and such holder, to execute and take such action on its behalf
under the provisions of this Agreement, the Notes, and the other Loan Documents
and to exercise such powers under the Loan Documents as are specifically
delegated to the Agent by the terms of the Loan Documents and such powers as are
reasonably incidental thereto. The Agent's duties shall be purely ministerial
and it shall have no duties or responsibilities except those expressly set forth
in the Loan Documents. The Agent shall not be required under any circumstances
to take any action that, in its judgment, (a) is contrary to any provision of
the Loan Documents or Applicable Law or (b) would expose it to any Liability or
expense against which it has not been indemnified to its satisfaction. The Agent
shall not, by reason of its serving as Agent, be a trustee or other fiduciary
for any Lender.

           Nothing in this Article 11 shall require the Agent to administer the
Swing Loans. The Swing Loan Lender shall have exclusive authority and
responsibility to administer the Swing Loans.

     11.2  Expenses; Indemnification.
           -------------------------

           In default of reimbursement or indemnification by the Borrower, the
Lenders will, in proportion to their respective portions of the Commitment or,
if none, the outstanding Loans, reimburse or indemnify, as the case may be, the
Agent for and against all expense, liability, penalty and damage of any nature
whatsoever (including but not limited to reasonable attorneys' fees) which may
be incurred or sustained by the Agent in any way in connection with the Loan
Documents or its duties under the Loan Documents provided that (i) no Lender
shall be liable for any portion of the foregoing items resulting from the gross
negligence or willful misconduct of the Agent and (ii) unless a Default or an
Event of Default has occurred and is continuing (or is believed by the Agent to
have occurred and be continuing), no Lender shall be liable for the normal
administrative costs and expenses of the Agent incidental to the performance of
its duties as Agent under the Loan Documents, but the Lenders shall be liable
for all out of pocket costs and expenses of the Agent (including out-of-pocket
administrative costs) during the existence of a Default or an Event of Default
(including one believed to exist by Agent). The Agent shall not have any
obligation to take any action in connection with the performance of its duties
as Agent under the Loan Documents which, in its opinion, requires the payment of
expenses or the incurrence of liability, if there is a reasonable ground for
belief that reimbursement of such expenses or liability is not reasonably
assured to it.


                                     -71-
<PAGE>
 
      11.3 Exculpatory Provisions.
           ----------------------

           Neither the Agent, nor any Lender constituting the Agent, nor any of
its respective officers, directors, employees or agents, shall be liable for any
action taken or omitted under the Loan Documents or in connection with the Loan
Documents unless caused by its or their gross negligence or willful misconduct.
The Agent shall not be responsible for any recitals, warranties or
representations in the Loan Documents or for the validity, enforceability,
collectibility or due execution of this Agreement or any of the other Loan
Documents. The Lenders hereby acknowledge that they have reviewed this Agreement
and the other Loan Documents and are fully aware of the terms thereof. The Agent
may execute any of its duties by or through agents or employees and shall be
entitled to advice of counsel, accountants or other professionals of its
selection concerning all matters pertaining to the Loan Documents and its duties
under the Loan Documents. The Agent shall be entitled to rely upon any writing
or other document, telegram or telephone conversation believed by it to have
been signed, sent or made by the proper person or persons and, in respect of
legal matters, upon the advice of counsel selected by the Agent whether or not
such advice is correct. With respect to the portion of the Loans made by it and
Notes issued to it, the Agent shall have the same rights and powers under the
Loan Documents as any other Lender or holder of a Note and may exercise the same
as though it were not the Agent, and the term "Lenders" or "holders of Notes" or
any similar term shall, unless the context otherwise indicates, include the
Agent in its capacity as a Lender or noteholder.

      11.4 Investigation by Lenders.
           ------------------------

           Each Lender expressly acknowledges that the Agent has not made any
representation or warranty to it and that no act taken by the Agent shall be
deemed to constitute a representation or warranty by the Agent to the Lenders.
Each Lender further acknowledges that it has taken and will continue to take
such action and to make such investigation as it deems necessary to inform
itself of the affairs of the Borrower and other Loan Parties and that it has
made and will continue to make its own independent investigation of the
creditworthiness and the business and operations of the Borrower and other Loan
Parties. In entering into this Agreement, and in making an advance under this
Agreement, each Lender represents that it has not relied and will not rely upon
any information or representations furnished or given by the Agent or by any
other Lender. The Agent shall be under no duty or responsibility to the Lenders
to ascertain or to inquire into the performance or observance by the Borrower or
any other Loan Party of any of the provisions of this Agreement or any document
or instrument now or hereafter executed in connection with this Agreement. For
all purposes under the Loan Documents, the Agent shall not be deemed to have
knowledge of the occurrence of a Default (other than the non-payment to it of
fees or principal of or interest on Loans) unless the Agent has received a
written notice from a Lender or the Borrower specifying such Default and stating
that such notice is a "Notice of Default."

<PAGE>
 
      11.5 Amendments, Waivers and Consents.
           --------------------------------

           With the written consent of the Requisite Lenders, or all the Lenders
as required by Subsection 12.4.2, or as otherwise specified in said Subsection
12.4.2, the Agent may, on behalf of the Lenders, enter into agreements which
change, amend or supplement this Agreement or any other Loan Document, and may
waive compliance with any provision of any of the Loan Documents.

      11.6 Action Upon Defaults.
           ---------------------  

           11.6.1 Acceleration. Upon the occurrence and during the continuation
                  ------------
of an Event of Default, the Agent may (if in its sole discretion it determines
that it shall not be exposed to liability and that the exigencies so require)
and upon the request of the Requisite Lenders shall declare the Notes to be due
and payable and proceed to enforce the rights of the holders of the Notes by
such proceedings as the Agent may deem appropriate, whether at law or in equity.
Upon any request as aforesaid, the Agent shall declare the Notes to be due and
payable, but the Agent shall be justified in failing or refusing to take any
further action unless it shall be indemnified to its satisfaction or if it shall
reasonably determine that such action may expose the Agent to liability. It is
agreed that if the Agent, having been so indemnified to its satisfaction as
aforesaid, or not having been so indemnified, shall fail to so proceed, the
Requisite Lenders (acting through any Lender) shall be entitled to take such
action as they shall deem appropriate to enforce their rights.

      11.7 Instructions
           ------------

           The Agent shall in all cases be fully protected in acting, or in
refraining from acting, under the Loan Documents (i) in accordance with written
instructions of the Requisite Lenders or all Lenders, as applicable, or (ii) in
accordance with the advise of legal counsel whether or not such advice shall
ultimately be determined to be correct or (iii) as a court of competent
jurisdiction may direct.

      11.8 Resignation; Termination.
           -------------------------     

           The Agent may resign at any time by giving prior written notice to
the Borrower and the Lenders. The Agent may be removed at any time with cause by
the Requisite Lenders. Such resignation or removal shall take effect at the end
of the sixty (60) day period after such notice of resignation or removal has
been given or upon the earlier appointment of a successor agent by the Requisite
Lenders. The Lenders shall, upon receipt of such notice, appoint a successor
agent from among the Lenders (subject if no Default or Event of Default shall
have then occurred and be continuing to the consent of the Borrower, which
consent shall not be unreasonably withheld), and the Lenders and the Borrower
shall execute such documents as shall be necessary to effect such appointment.
If no successor Agent shall have been so appointed by the Requisite Lenders and
shall have accepted such appointment within 30 days after the retiring Agent's
giving of notice of resignation, then the retiring Agent may, on behalf of the
Lenders and if no Default or Event of Default shall have then occurred and be
continuing with the consent of 

                                     -73-
<PAGE>
 
the Borrower (which consent shall not be unreasonably withheld), appoint any
bank or financial institution as the successor Agent. Upon the acceptance by any
Person of its appointment as a successor Agent, such Person shall thereupon
succeed to and become vested with all the rights, powers, privileges, duties and
obligations of the retiring Agent and the retiring Agent shall be discharged
from its duties and obligations as Agent under the Loan Documents. After any
retiring Agent's resignation as Agent, the provisions of this Article 11 and all
indemnification and expense provisions 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.

           Nothing in this Section 11.9 is intended to limit the right of the
Swing Loan Lender to accept and retain payments in respect of any Swing Loan in
the ordinary course of business so long as no Default or Event of Default has
occurred and is continuing.

      11.9 Sharing.
           -------

           If any Lender shall at any time receive payment of or on account of
all or a part of any Note held by it, whether by set-off or otherwise, in a
greater proportion than the payments made on the Notes held by the other
Lenders, such Lender shall purchase, without recourse, for cash, ratably from
each of the other Lenders, such portion of the Notes held by such other Lenders
so that, after such purchase, each Lender will hold an unpaid principal amount
of Notes in the same proportion that the outstanding principal balance due to
such Lender immediately prior to such payment bore to the aggregate outstanding
principal balance due to all Lenders immediately prior to such payment. In the
event that, at any time, any Lender shall be required to refund any amount which
has been paid to or received by it on account of any Note held by it, and which
has been applied to the purchase of a portion of the Notes held by other Lenders
pursuant to this Section, then, upon notice from such Lender, each of the other
Lenders shall purchase, without recourse, its portion for cash, to the extent of
its ratable share thereof, of the Notes held by the Lender required to make such
refund.

     11.10 Other Relationships.
           -------------------           

           It is acknowledged that the Agent and the Lenders may now or
hereafter have lending or other relationships with the Borrower or other Loan
Parties and with Affiliates of such Persons, and it is agreed that the Agent and
the Lenders are free to act with respect thereto without consulting with one
another and without regard to the effect of any such action or relationship upon
the Loans, or any rights or obligations under the Loan Documents.

the Agent shall not be effective until received. Any Lender giving any notice to
the Borrower shall simultaneously send a copy of such notice to the Agent, and
the Agent shall promptly notify the other Lenders of the receipt by it of any
such notice. Except as otherwise provided in this Agreement, in the event of a
discrepancy between any telephonic or written notice, the written notice shall

      12.2 Duration; Survival.
           ------------------     

           All representations and warranties of the Borrower and other Loan
Parties contained in the Loan Documents shall survive the making of the Loans
and shall not be waived by the execution and delivery of this Agreement, any
investigation by the Agent or the Lenders, the making of the Loans, or payment
in full of the Loans.

      12.3 No Implied Waiver.
           -----------------     

           No failure or delay on the part of the Agent or any Lender in
exercising any right, power or privilege under any or all of the Loan Documents
and no course of dealing between the Borrower and/or and the Agent or any Lender
shall operate as a waiver of any such right, power or privilege; nor shall any
single or partial exercise of any right, power or privilege under the Loan
Documents preclude any other or further exercise of any such right, power or
privilege or the exercise of any other right, power or privilege. The rights and
remedies expressly provided in the Loan Documents are cumulative and not
exclusive of any rights or remedies which Agent or any Lender would otherwise
have. No notice to or demand on the Borrower or any other Loan Party in any case
shall entitle the Borrower or any other Loan Party to any other or further
notice or demand in similar or other circumstances or shall constitute a waiver
of the right of the Agent or any Lender to take any other or further action in
any circumstances without notice or demand.

      12.4 Entire Agreement and Amendments
           -------------------------------     

           12.4.1 Entire Agreement. This Agreement and the other Loan Documents

represent the entire agreement between the parties to this Agreement with
respect to the Commitment, the Loans and the transactions contemplated under the
Loan Documents and, 


                                     -75-
<PAGE>
 
except as expressly provided in the Loan Documents, shall not be affected by
reference to any other documents.

           12.4.2 Amendments; Waivers. Any term, covenant, agreement or
                  -------------------
condition of any Loan Document to which the Lenders (or the Agent) are party may
be amended, and any right under the Loan Documents may be waived, if, but only
if, such amendment or waiver is in writing and is signed by the Requisite
Lenders (or by the Agent at the direction of the Requisite Lenders) provided,
however, if the rights and duties of the Agent are affected thereby such
amendment or waiver must be executed, by the Agent; provided further, that no
                                                    ----------------
such amendment or waiver shall be effective unless in writing and signed by all
Lenders if it shall

           (a) increase the maximum amount of the Loans or the Commitment; or

           (b) extend the maturity of any Note or decrease the rate of interest
or amount of fees or decrease the principal amount of any Note or extend the
time of payment of interest or fees, provided that the written consent of the
Requisite Lenders, rather than the consent of all Lenders, shall be sufficient
to waive imposition of the Default Rate, or

           (c) amend the definition of "Requisite Lenders," or

           (d) change the number of Lenders which are required to consent to any
proposed action under this Agreement before such action may be taken under this
Agreement, or

           (e) release any guaranty granted pursuant to the Loan Documents;
provided, however, the Agent may without the consent of any Person release any
guarantor (i) as a court of competent jurisdiction may direct, or (ii) in
connection with a disposition permitted under Section 9.6, above (other than a
disposition to the Borrower or a Subsidiary of the Borrower) or as may be
otherwise provided under the Loan Documents.

It is understood and agreed that, (x) except for Section 11.8 hereof, the Agent
and the Lenders may amend or modify the provisions of Article 11 hereof without
the need for any consent or approval from the Borrower, it being acknowledged
that the Borrower is not a third party beneficiary of the provisions of said
Article 11 except for said Section 11.8 and (y) without the consent of any
Lenders, the Agent may enter into amendments and modifications to this Agreement
and the other Loan Documents as necessary or desirable to add additional
Subsidiary Guarantors and (2) the Borrower and Swing Loan Lender may without the
consent of any other party hereto amend the terms of any agreement or instrument
relating to the Swing Loans (other than the terms of this Agreement) to the
extent that such terms relate to the time, place or manner of making or repaying
Swing Loans or relate to interest rate provisions or similar matters so long as
such terms are not inconsistent with the terms of this Agreement.

           12.5.1 Assignments by the Borrower. Without the prior written consent
                  ---------------------------                
of all of the Lenders, the Borrower may not assign any of its rights or delegate
any of its duties or obligations under this Agreement or the other Loan
Documents.

           12.5.2 Participation. Each Lender may sell participations to one or
                  -------------
more Eligible Institutions of all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment); provided, however, that (i) such Lender's obligations under this
             --------- -------   
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties to this Agreement for the performance of such
obligations, (iii) all amounts payable by the Borrower under this Agreement
shall be determined as if such transferor Lender had not sold such participation
and no participant shall be entitled to receive any greater amount pursuant to
this Agreement than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred by such transferor Lender
to such participant had no such transfer occurred, (iv) each such participation
shall be of a constant, and not a varying percentage of all the transferor
Lender's interests, rights and obligations under this Agreement, (v) such
participant shall agree to be bound by the provisions of this Agreement and the
other Loan Documents, (vi) the interest subject to such participation shall be
at least Five Million Dollars ($5,000,000.00), and (vii) the Borrower, the Agent
and the other Lenders shall continue to deal solely and directly with such
transferor Lender in connection with such Lender's rights and obligations under
this Agreement, and such Lender shall retain the sole right and responsibility
vis-a-vis the Borrower to enforce the obligations of the Borrower relating to
the Loans including, without limitation, the right to approve any amendment,
modification or waiver of any provision of this Agreement (subject to the rights
of the participants to approve amendments, modifications or waivers which would
reduce the interest or fees payable to them under this Agreement or increase the
amount of the Commitment, or extend the maturity date of the Loans).

           12.5.3 Assignments by Lenders. Each Lender may assign to one or more
                  ----------------------     
Eligible Institutions all or a portion of its interest, rights and obligations
under this Agreement (including without limitation all or a portion of its
Commitment) and the other Loan Documents; provided, however, that each of the
                                          --------- --------      
following conditions must be satisfied:

           (i) unless the assignee is (prior to the effective time of the
assignment) an existing Lender or an Affiliate of an existing Lender, the Agent
and, if no Event of Default has occurred and is continuing, the Borrower must
give their prior written consent to such assignment (which consents shall not be
unreasonably withheld or delayed),

           (ii) each such assignment shall be of a constant, and not a varying
percentage of all the assigning Lender's interests, rights and obligations under
this Agreement,

           (iii) the parties to each such assignment shall execute and deliver
to the Agent, for its acceptance and the Borrower's acceptance, an Assignment
and Acceptance Agreement in form and content satisfactory to the Agent (the
"Assignment and Acceptance"), together with (A) any Note subject to such
- --------------------------
assignment, and, (B) unless the 

                                     -77-
<PAGE>
 
assignee is at the time of such assignment also a Lender hereunder, a processing
and recordation fee of $3,500, and (C) reimbursement for fees of Agent's counsel
in connection with services rendered and other costs and expenses in respect of
such assignment (which amounts are payable by the applicable assignee and
assignor) and

           (iv) no Lender may make a partial assignment if the aggregate amount
of the Commitment assigned is less than Five Million Dollars ($5,000,000).

The Agent (in its capacity as a Lender), without the consent of the Borrower,
shall not make any partial assignment if its portion of the Commitment is, or
after giving effect to the assignment would be, less than 49% of the amount of
the Agent's Commitment on the Closing Date. "Partial assignment" as used in
clause (iv) above means any assignment of a Lender's rights and obligations
hereunder except an assignment of all of such Lender's rights and obligations
such that after the assignment such Lender shall have no Commitment and no
interest in any Loans hereunder. Upon compliance with clauses (i) through (iv)
above from and after the effective date specified in the relevant Assignment and
Acceptance, (x) the assignee shall be a party to this Agreement and the other
Loan Documents to which the assignor was a party, and to the extent provided in
such Assignment and Acceptance have the rights and obligations of a Lender under
this Agreement and under the other Loan Documents and (y) the assigning Lender
shall, to the extent provided in such Assignment and Acceptance, be released
from its obligations under this Agreement and the other Loan Documents.

           12.5.4 Procedures Respecting Assignment. Upon their receipt of an
                  --------------------------------      
Assignment and Acceptance executed by the assignor and the assignee, subject to
the conditions set forth in Subsection 12.5.3, the Agent and the Borrower shall
accept such Assignment and Acceptance. Within five (5) Business Days after such
Assignment and Acceptance is signed and accepted by all parties, the Borrower
shall execute and deliver to the Agent new Notes in exchange for the surrendered
Notes, each to the order of such assignee in an amount equal to its portion of
the Commitment and Loans assigned to it pursuant to such Assignment and
Acceptance and new Notes to the order of the assigning Lender in an amount equal
to the Commitment and Loans retained by it. Such Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Notes, shall be dated the date of such surrendered Notes (each assignee shall
confirm in the Assignment and Acceptance that, notwithstanding the date of the
new Notes made in favor of such assignee, such assignee shall have no right to,
or interest in, any fees or interest which shall have accrued on the Loans prior
to the effective date of the Assignment and Acceptance). Cancelled Notes shall
be returned to the Borrower upon the execution of such new Notes.

           12.5.5 Assignments to Federal Reserve Bank. Notwithstanding any of
                  -----------------------------------
the terms of this Section 12.5, any Lender may assign all or any portion of its
rights to payments in connection with this Agreement to a Federal Reserve Bank
as collateral in accordance with Regulation A of the Board of Governors of the
Federal Reserve System. Such assignment shall not affect any other rights or any
obligations of the assigning Lender.

shall be governed by the laws of the Commonwealth of Pennsylvania.

    12.8   Holidays
           --------

           Except as otherwise provided herein, whenever any payment to be made
under the Loan Documents shall become due and payable on a day which is not a
Business Day, such payment may be made on the next succeeding Business Day and
such extension of time shall in such case be included in computing interest on
such payment.

    12.9   Counterparts.
           ------------

           The Loan Documents and any notice or communication under the Loan
Documents may be executed in one or more counterparts, each of which shall
constitute an original, but all of which together shall constitute one and the
same instrument. Delivery of a photocopy or telecopy of an executed counterpart
of a signature page to any Loan Document shall be effective as delivery of a
manually executed counterpart of such Loan Document.

    12.10  Maximum Lawful Interest Rate.
           ----------------------------

           Notwithstanding any provision contained in this Agreement or
the Notes, the total liability of the Borrower for payment of interest pursuant
to this Agreement and the Notes shall not exceed the maximum amount of such
interest permitted by law to be charged, collected, or received from the
Borrower, and if any payments by the Borrower include interest in excess of such
a maximum amount, each Lender shall apply such excess to the reduction of the
unpaid principal amount due pursuant to this Agreement and the Notes, or if none
is due, such excess shall be refunded to the Borrower.

           The Borrower and each Subsidiary thereof hereby pledges and gives to
each Lender a lien and security interest for the amount of the Obligations owing
to such Lender under the Loan Documents upon and in the balance of any account
maintained by the Borrower or any such Subsidiary with such Lender or any other
liability of Lender to such Subsidiary or the Borrower. Upon the occurrence of
and throughout the period in which there is continuing an Event of Default, in
such Lender's sole option, at any time and from time to time, the Borrower and
each Subsidiary thereof hereby authorizes such Lender to apply any such deposit
balances now or hereafter in the possession of such Lender and/or a credit in
the amount of any such other liability to the payment of the Obligations owing
to such Lender under the Loan Documents. The provisions of this Section 12.11
shall not be deemed or construed to limit rights of set-off or liens or similar
rights which any Lender may otherwise have by reason of applicable law or
otherwise.

     12.12 Severability.
           ------------             

           Every provision of this Agreement and each of the other Loan
Documents is intended to be severable, and if any term or provision of this
Agreement or any of the other Loan Documents shall be invalid, illegal or
unenforceable for any reason, the validity, legality and enforceability of the
remaining provisions shall not be affected or impaired thereby, and any
invalidity, illegality or unenforceability in any jurisdiction shall not affect
the validity, legality or enforceability of any such term or provision in any
other jurisdiction.

     12.13 Non-Merger of Remedies.
           ----------------------             

           It is the intention of the parties hereto that the covenants and
obligations of the Borrower and its Subsidiaries and the rights and remedies of
the Agent and Lenders hereunder and under the other Loan Documents shall not
merge with or be extinguished by the entry of judgment hereunder or thereunder,
and such covenants, obligations, rights and remedies shall survive any entry of
judgment until payment in full of the Loans. All obligations under the Loan
Documents shall continue to apply with respect to and during the collection of
amounts due under the Loan Documents or the proof and allowability of any claim
arising under this Agreement or any other Loan Document, whether in bankruptcy
or receivership proceedings or otherwise, and in any workout, restructuring or
in connection with the protection, preservation, exercise or enforcement of any
of the terms of this Agreement or of any rights under this Agreement or under
any other Loan Document or in connection with any foreclosure, collection or
bankruptcy proceedings. Without limiting the generality of the foregoing,
post-judgment interest rate shall be the interest rate provided herein.

     12.14 Payment and Reimbursement of Costs and Expenses; Indemnification.
           ----------------------------------------------------------------

           Whether or not any fundings are made under this Agreement, the

Affiliates, officers, directors, employees, agents, attorneys, shareholders and
consultants (collectively, "Indemnitees") harmless against, any and all

<PAGE>
 
limitation, fees and disbursements of legal counsel, accountants, investigators
and other experts, whether or not they are employees of the Agent) imposed on,
incurred by or asserted against such Indemnitees and arising out of, relating to
or connected with: (a) the negotiation, preparation, execution and delivery of
the Loan Documents and any waiver, amendment or consent under or with respect to
any of the Loan Documents whether or not executed, (b) consulting with respect
to any matter in any way arising out of, related to, or connected with, the Loan
Documents, including (i) the protection, preservation, exercise or enforcement

by the Lenders provided, however, with respect to liabilities, losses, costs,
               --------
expenses, claims and/or charges referred to in clauses (a) through (d) above to
the extent that they are imposed on, incurred by or asserted against a Lender
(as compared to the Agent or someone acting on behalf of the Agent), the
indemnification of such Lender pursuant to this Section 12.14 shall be limited
to amounts that accrue after the occurrence of an Event of Default and provided,
                                                                       -------- 
further, that, unless an Event of Default shall have occurred and be continuing,
the Borrower shall not be responsible for any costs or expenses (including legal
fees) in connection with the assignment or participation of any interests by any
Lender hereunder. Notwithstanding the limitations set forth in the provisos in
the preceding sentence, the Swing Loan Lender shall be entitled to the
indemnifications set forth in this Section 12.14 for all losses, costs,
expenses, claims and/or charges relating to Swing Loans whether or not a Default
or Event of Default shall have occurred.

           Without limiting the generality of the foregoing, the Borrower hereby
indemnifies and agrees to defend and hold harmless each Indemnitee, from and
against any and all claims, actions, causes of action, liabilities, penalties,
fines, damages, judgments, losses, suits, expenses, legal or administrative
proceedings, interest, costs and expenses (including court costs and attorneys',
consultants' and experts' fees) arising out of or in any way relating to: (i)
the use, handling, management, production, treatment, processing, storage,
transfer, transportation, disposal, Release or threat of Release of any
Hazardous Substance by or on behalf of, Borrower or any Subsidiary thereof; (ii)
the presence of Hazardous Substances on, about, beneath or arising from any
premises owned or occupied by the Borrower or any Subsidiary thereof (herein
collectively, the "Premises"); (iii) the failure of Borrower or any of its
                   --------     
Subsidiaries or Affiliates or any occupant of any Premises to comply with the
Environmental Laws; (iv) Borrower's breach of any of the representations,
warranties and covenants contained herein or in any Loan Documents; (v)
Regulatory Actions (as hereinafter defined) and Third Party Claims (as
hereinafter defined); or (vi) the imposition or recording of a Lien against any
Premises in connection with any Release at, on or from any Premises or any
activities undertaken on or occurring at any Premises, or arising from such
Premises or pursuant to any Environmental Law. Borrower's indemnity and defense
obligations under this section shall include, without limitation 

                                     -81-
<PAGE>
 
and whether foreseeable or unforeseeable, any and all costs related to any
Remedial Action. "Regulatory Action" means any notice of violation, citation,
                  -----------------
complaint, request for information, order, directive, compliance schedule,
notice of claim, consent decree, action, litigation or proceeding brought or
instituted by any governmental authority under or in connection with any
Environmental Law involving the Borrower any Subsidiary of the Borrower, or any
occupant of any of the Premises or involving any of the Premises or any
activities undertaken on or occurring at any Premises. "Third Party Claims"
                                                        ------------------
means claims by a party (other than a party to this Agreement and other than
Regulatory Actions) based on negligence, trespass, strict liability, nuisance,
toxic tort or detriment to human health or welfare due to Hazardous Substances
on, about, beneath or arising from any Premises or in any way related to any
alleged violation of any Environmental Laws or any activities undertaken on or
occurring at any Premises.

           The indemnities contained herein shall survive repayment of the Loans
and satisfaction, release, and discharge of the Loan Documents, whether through
full payment of the Loans, foreclosure, deed in lieu of foreclosure or
otherwise.

           The foregoing amounts are in addition to any other amounts which may
be due and payable to the Agent and/or the Lenders under this Agreement. A
certification by the Agent or a Lender hereunder of the amount of liabilities,
losses, costs, expenses, claims and/or charges shall be conclusive, absent
manifest error. Notwithstanding the foregoing, the Borrower shall not be
required to indemnify any Indemnitee with respect to a claim or liability that
arises as the result of the gross negligence or willful misconduct of such
Indemnitee.

     12.15 Arbitration
           -----------

              (a)  Upon demand of any party hereto, whether made before or after
institution of any judicial proceeding, any claim or controversy arising out of,
or relating to the Loan Documents between the parties (a "Dispute") hereto shall
be resolved by binding arbitration conducted under and governed by the
Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules") of the
American Arbitration Association (the "AAA") and the Federal Arbitration Act.
Disputes may include, without limitation, tort claims, counterclaims, a dispute
as to whether a matter is subject to arbitration, claims brought as class
actions, or claims arising from documents executed in the future. A judgment
upon the award may be entered in any court having jurisdiction. Notwithstanding
the foregoing, this arbitration provision does not apply to disputes under
related to swap agreements.

              (b)  All arbitration hearings shall be conducted in the city of
Philadelphia, State of Pennsylvania unless otherwise agreed by all parties to
such arbitration. A hearing shall begin within 90 days of demand for arbitration
and all hearings shall conclude within 120 days of demand for arbitration. These
time limitations may not be extended unless a party shows cause for extension
and then for no more than a total of 60 days. The expedited procedures set forth
in Rule 51 et seq. of the Arbitration rules shall be applicable to claims of
           ------
less than $1,000,000.00. Arbitrators shall be licensed attorneys selected from
the Commercial 

                                     -82-
<PAGE>
 
Financial Dispute Arbitration Panel of the AAA. The parties do not waive
applicable Federal or state substantive law except as provided herein.

              (c)  Notwithstanding the preceding binding arbitration provisions,
the parties agree to preserve, without diminution, certain remedies that any
party may exercise before or after an arbitration proceeding is brought. The
parties shall have the right to proceed in any court of proper jurisdiction or
by self-help to exercise or prosecute the following remedies, as applicable: (i)
all rights to foreclose against any real or personal property or other security
by exercising a power of sale or under applicable law by judicial foreclosure
including a proceeding to confirm the sales; (ii) all rights of self-help
including peaceful occupation of real property and collection of rents, set-off,
and peaceful possession of personal property; (iii) obtaining provisional or
ancillary remedies including injunctive relief, sequestration, garnishment,
attachment, appointment of receiver and filing of involuntary bankruptcy
proceedings; and (iv) when applicable, a judgment by confession of judgment. Any
claim or controversy with regard to any party's entitlement to such remedies is
a Dispute.

              (d)  The parties agree that they shall not have a remedy of
punitive or exemplary damages against other parties in any Dispute and hereby
waive any right or claim to punitive or exemplary damages they have now or which
may arise in the future in connection with any Dispute whether the Dispute is
resolved by arbitration or judicially.

     12.16 Consent to Jurisdiction, Service and Venue; Waiver of Jury Trial
