          "Interest Period" shall mean, with respect to the Adjusted Libor Rate,
           ---------------

continuance of an Event of Default hereunder, including after maturity and upon
judgment, Borrower hereby agrees to pay to Banks interest (A) on any outstanding
Libor Portion, at the rate which is two percent (2%) per annum in excess of the

               (c) Procedure for Determining Interest Periods and Rates of
                   -------------------------------------------------------
Interest.
-------- 

          (i) If Borrower elects the rate based on the Base Rate to be
applicable to a Portion, Borrower must notify Agent of such election in writing
prior to eleven o'clock (11:00) a.m. Philadelphia time one (1) Business Day
prior to the proposed application of such rate.  If Borrower elects the rate
based on the Adjusted Libor Rate to be applicable to a Portion, Borrower must
notify Agent of such election and the Interest Period selected prior to eleven
o'clock (11:00) a.m. Philadelphia time at least three (3) London Business Days
prior to the commencement of the proposed Interest Period.  If Borrower does not
provide notice for the rate based on the Adjusted Libor Rate, then Borrower
shall be deemed to have requested that the rate based on the Base Rate shall
apply to any Portion as to which the Interest Period is expiring and to any new
Advance of the Loan until Borrower shall have given proper notice of a change in
or determination of the rate of interest in accordance with this Paragraph
2.6(c).

                                      -23-
<PAGE>
 
          (ii) Borrower shall not elect more than eight (8) different Libor
Portions to be applicable to the Loan at one time, and any Libor Portion shall
be in an amount equal to One Million Dollars ($1,000,000) or an even multiple of
Two Hundred Fifty Thousand Dollars ($250,000) in excess thereof.

          (d) Payment and Calculation of Interest.  With respect to Portions
              -----------------------------------                           
which bear interest at the rate based on the Adjusted Libor Rate, interest shall
be due and payable on the last day of each Interest Period for each such
Portion, and, in the case of a Libor Portion with an Interest Period of six (6)
months, on the ninetieth (90) day after the commencement of such Interest Period
and on the last day of the Interest Period.  With respect to Portions which bear
interest at the rate based on the Base Rate, interest shall be due and payable
on the last Business Day of each month commencing on the first such date after
the first Advance which bears interest at the rate based on the Base Rate.
Interest shall be calculated in accordance with the provisions of Paragraph
2.6(b) hereof; all interest shall be calculated on the basis of the actual
number of days elapsed over a year of three hundred sixty (360) days.

          (e) Reserves.  If at any time when a Portion is subject to the rate
              --------                                                       
based on the Adjusted Libor Rate, a Bank (or a bank Affiliate of such Bank) is
subject to and incurs a Reserve, other than a Reserve Percentage provided in the
calculation of the applicable Adjusted Libor Rate, Borrower hereby agrees to pay
within five (5) Business Days of demand thereof from time to time, as billed by
Agent on behalf of itself or any other Bank, such additional amount as is
necessary to reimburse such Bank (or such Bank's bank Affiliate) for its costs
in maintaining such Reserve.  Such amount shall be computed by taking into
account the cost incurred by such Bank (or such Bank's bank Affiliate) in
maintaining such Reserve in an amount equal to such Bank's ratable share of the
Portion on which such Reserve is incurred, which computation shall be set forth
in any such demand by Agent on behalf of itself or any other Bank.  The
determination by Agent or any Bank of such costs incurred and the allocation of
such costs among Borrower and other customers which have similar arrangements
with such Bank (or such Bank's bank Affiliate) shall be prima facie evidence of
the correctness of the fact and the amount of such additional costs, if
calculated in a manner consistent with similar charges made by such Bank (or
such Bank's Affiliates) to its other customers having similar arrangements with
such Bank.  Each Bank acknowledges that on the date of this Agreement it is not
subject to any Reserve.  Upon notification to Borrower of any payment required
pursuant to this Paragraph 2.6(e), Borrower (A) shall make such payment in
accordance with the provisions hereof and (B) may repay the Portion of the Loan
with respect to which such payment is 

                                      -24-
<PAGE>
 
required, subject to the requirements of Paragraph 2.9 and 2.6(g) hereof.

          (f) Special Provisions Applicable to Adjusted Libor Rate.  The
              ----------------------------------------------------      
following special provisions shall apply to the Adjusted Libor Rate:

          (i) Change of Adjusted Libor Rate.  The Adjusted Libor Rate may be
              -----------------------------                                 
automatically adjusted by Agent on a prospective basis to take into account the
additional or increased cost of maintaining any necessary reserves for
Eurodollar deposits or increased costs due to changes in applicable law or
regulation or the interpretation thereof occurring subsequent to the
commencement of the then applicable Interest Period, including but not limited
to changes in tax laws (except changes of general applicability in corporate
income tax laws) and changes in the reserve requirements imposed by the Board of
Governors of the Federal Reserve System (or any successor), excluding the
Reserve Percentage and any Reserve which has resulted in a payment pursuant to
subparagraph (e) above, that increase the cost to Banks of funding the Loan or a
portion thereof bearing interest based on the Adjusted Libor Rate.  Agent shall
give Borrower notice of such a determination and adjustment, which determination
shall be prima facie evidence of the correctness of the fact and the amount of
such adjustment.  Borrower may, by notice to Agent, (A) request Agent to furnish
to Borrower a statement setting forth the basis for adjusting such Adjusted
Libor Rate and the method for determining the amount of such adjustment; and/or
(B) repay the Portion of the Loan with respect to which such adjustment is made,
subject to the requirements of Paragraph 2.9 and 2.6(g) hereof.

          (ii) Unavailability of Eurodollar Funds.  In the event that Borrower
               ----------------------------------                             
shall have requested the rate based on the Adjusted Libor Rate in accordance
with Paragraph 2.6(c) and any Bank (or such Bank's bank Affiliate) shall have
reasonably determined that Eurodollar deposits equal to the amount of the
principal of the Portion and for the Interest Period specified are unavailable,
or that the rate based on the Adjusted Libor Rate will not adequately and fairly
reflect the cost of making or maintaining the principal amount of the Portion
specified by Borrower during the Interest Period specified, or that by reason of
circumstances affecting Eurodollar markets, adequate and reasonable means do not
exist for ascertaining the rate based on the Adjusted Libor Rate applicable to
the specified Interest Period, such Bank shall give notice to Agent and Agent
shall promptly give notice of such determination to Borrower that the rate based
on the Adjusted Libor Rate is not available.  A determination by such Bank (or
such Bank's bank Affiliate) hereunder shall be prima facie evidence of the
correctness of the fact and amount of such additional costs or unavailability.
Upon 

                                      -25-
<PAGE>
 
such a determination, (i) the obligation to advance or maintain Portions at the
rate based on the Adjusted Libor Rate shall be suspended until Agent shall have
notified Borrower and Banks that such conditions shall have ceased to exist, and
(ii) the rate based on the Base Rate shall be applicable to all such Portions.

          (iii)  Illegality.  In the event that it becomes unlawful for a Bank
                 ----------                                                   
(or such Bank's bank Affiliate) to maintain Eurodollar liabilities sufficient to
fund any Portion of the Loan subject to the rate based on the Adjusted Libor
Rate, then such Bank shall immediately notify Borrower thereof (with a copy to
Agent) and such Bank's obligations hereunder to advance or maintain advances at
the rate based on the Adjusted Libor Rate shall be suspended until such time as
such Bank (or such Bank's bank Affiliate) may again cause the rate based on the
Adjusted Libor Rate to be applicable to any Portion of the outstanding principal
balance of the Loan and any such Bank's share of any Portion shall then be
subject to the rate based on the Base Rate.

          (g) Funding Costs and Loss of Earnings.  In the event that Borrower
              ----------------------------------                             
shall have requested the Adjusted Libor Rate to be applicable to a Portion to be
Advanced and Borrower shall revoke the request for such Advance or shall fail to
meet the conditions to such Advance as set forth in Section Four hereof, and in
connection with any prepayment or repayment of a Portion bearing interest at the
rate based on the Adjusted Libor Rate made on other than the last day of the
applicable Interest Period, whether such prepayment or repayment is voluntary,
mandatory, by demand, acceleration or otherwise, Borrower shall pay to Banks all
reasonable funding costs and loss of earnings which may arise in connection with
such revocation of request for or failure to meet the conditions to such Advance
or such prepayment or repayment, as calculated by Agent in accordance with
Exhibit G hereto.

subparagraph (a) or (b) above, Agent shall request by prompt notice to Banks
that each Bank advance funds to Agent so that each Bank participates in the
requested Advance in the same percentage as it participates in the applicable
Commitment.  In the case of a request for an Advance under the Acquisition
Commitment, Agent shall promptly provide copies of the Advance Request Form and
all attachments and information provided therewith to the Banks.  Each Bank
shall advance its applicable percentage of the requested Advance to Agent by
delivering federal funds immediately available at Agent's offices prior to
twelve o'clock (12:00) noon on the date of the Advance.  Subject to the
satisfaction of the terms and conditions hereof, Agent shall make the requested
Advance available to Borrower by crediting such amount to Borrower's deposit
account with Agent not later than two o'clock (2:00) p.m. on the day of the
requested Advance; provided, however, that in the event Agent does not receive a
Bank's share of the requested Advance by such time as provided above, Agent
shall not be obligated to advance such Bank's share.

          (ii) Unless Agent shall have been notified by a Bank prior to the date
such Bank's share of any such Advance is to be made by such Bank that such Bank
does not intend to make its share of such requested Advance available to Agent,
Agent may assume that such Bank has made such proceeds available to Agent on
such date, and Agent may, in reliance upon such assumption (but shall not be
obligated to), make available to Borrower a corresponding amount.  If such
corresponding amount is not in fact made available to Agent by such Bank on the
date the Advance is made, Agent shall be entitled to recover such amount on
demand from such Bank (or, if such Bank fails to pay such amount forthwith upon
such demand, from Borrower) together with interest thereon in respect of each
day during the period commencing on the date such amount was made available to
Borrower and ending on (but excluding) the date Agent recovers such amount, from
such Bank, at a rate per annum equal to the effective rate for overnight federal
funds in New York as reported by the Federal Reserve Bank of New York for such
day (or, if such day is not a Business Day, for the next preceding Business Day)
and from Borrower, at a rate per annum as provided in Paragraph 2.6(b)(i)(A)
hereof.

          (d) Requests Irrevocable.  Each request for an Advance pursuant to
              --------------------                                          
this Paragraph 2.7 shall be irrevocable and 

                                      -28-
<PAGE>
 
binding on Borrower. In the case of any Advance bearing interest at the rate
based upon the Adjusted Libor Rate, Borrower shall indemnify Banks against any
loss, cost or expense incurred by Bank as a result of not borrowing such funds
on the requested Advance date, including as a result of any failure to fulfill
on or before the date specified in such request for an Advance the applicable
conditions set forth in Section Four hereof, including, without limitation, any
loss, cost or expense incurred by reason of the liquidation or redeployment of
deposits or other funds acquired by Banks to fund the Advance to be made by
Banks when such Advance, as a result of such failure, is not made on such date,
as calculated by Agent in accordance with Exhibit G attached hereto.

          2.8.  Reduction and Termination of Commitment.
                --------------------------------------- 

          (a)  Borrower.  Borrower shall have the right at any time and from
               --------

reduce the Revolving Commitment, the Acquisition Commitment, the RSD Commitment
and/or the LHS Commitment in whole or in part in increments aggregating
$1,000,000 or multiples thereof without penalty or premium, provided that on the
effective date of such reduction Borrower shall make a prepayment of the
Revolving Loan, the Acquisition Loan or both in an amount, if any, by which the
aggregate outstanding principal balance of the applicable Loan exceeds the
amount of the applicable Commitment as then so reduced, together with accrued
interest on the amount so prepaid and any amounts due pursuant to Paragraph
2.6(g) hereof.

          (b)  Banks.  Required Banks shall have the right to terminate the
               -----                                                       
Revolving Commitment, the Acquisition Commitment, the RSD Commitment, the LHS
Commitment, or any of them at any time, in their discretion and upon notice to
Borrower, upon the occurrence of any Event of Default hereunder (except if an
Event of Default described in Paragraph 8.1(i) shall occur, in which case
termination of the Commitment shall occur automatically).

          (c) Restoration Only With Consent.  Except as provided in Paragraph
              -----------------------------                                  
2.1(e) hereof, any termination or reduction of the Revolving Commitment, the
Acquisition Commitment, the RSD Commitment, the LHS Commitment or any of them
pursuant to subparagraphs 2.8(a) and (b) shall be permanent, and such Commitment
cannot thereafter be restored or increased without the written consent of Banks.

          2.9.  Prepayment.
                ---------- 

          (a) Upon one (1) Business Day's prior written notice by Borrower to
Agent, Borrower may repay all or any 

                                      -29-
<PAGE>
 
portion of the outstanding principal balance under the Revolving Loan, the
Acquisition Loan, the RSD Loan or the LHS Loan without premium or penalty,
provided that any such payment shall include all accrued interest on the amount
prepaid plus any amounts which may be due pursuant to Paragraph 2.6(g) hereof.

          (b) Upon any sale of assets pursuant to the proviso to Paragraph
6.7(a), Borrower shall pay to Agent, for application to the Loan in accordance
herewith an amount equal to the full amount of cash proceeds received in
connection with such sale of assets, together with accrued and unpaid interest
on the amount so repaid and all amounts due pursuant to Paragraph 2.6(g) hereof.
Any such payment shall be applied to the Loan as follows: first, if the assets
sold relate to the business financed thereby, to the LHS Loan or RSD Loan, as
applicable; then, if applicable, to the principal balance of the Acquisition
Loan; then, if applicable, to the Revolving Loan; and then, if applicable, to
the RSD Loan and LHS Loan on a pro rata basis.

          (c) Payments made pursuant to Paragraph 2.9(a) or (b) prior to the
Revolving Commitment Termination Date or Acquisition Termination Date, as the
case may be, shall not reduce the Commitment and may be reborrowed in accordance
with this Agreement.

          2.10.  Payments.  All payments of principal, interest, fees and other
                 --------                                                      
amounts due hereunder, including any prepayments thereof, shall be made by
Borrower to Agent for the account of Banks in immediately available funds before
twelve o'clock (12:00) noon, Philadelphia time, on any Business Day at the
office of Agent set forth on Schedule 1 hereto.  Borrower hereby authorizes
Agent to charge Borrower's account with Agent for all payments of principal,
interest and fees when due hereunder.

          2.11.  Commitment Fee.  Borrower shall pay to Agent, for the benefit
                 --------------                                               
of Banks in accordance with their Pro Rata Shares, a non-refundable commitment
fee at the rate of three-eighths of one percent (3/8%) per annum on the
unborrowed portion of the Revolving Commitment, Acquisition Commitment, RSD
Commitment and LHS Commitment from the date hereof through the Revolving
Commitment Termination Date, the Acquisition Commitment Termination Date, the
RSD Commitment Termination Date or the LHS Commitment Termination Date,
respectively, which fees shall be payable at the offices of Agent quarterly in
arrears on the first day of each June, September, December and March and on the
applicable Termination Date. The commitment fee shall be calculated on the basis
of the actual number of days elapsed over a year of three hundred sixty (360)
days.

          Borrower and Banks hereby agree that for purposes of calculating the
commitment fee to be paid from time to time under 

                                      -30-
<PAGE>
 
this Paragraph 2.11, the unborrowed portion of the Revolving Commitment (on
which such fee is calculated) shall be reduced by the amount available to be
drawn under outstanding Letters of Credit and the amount of any unreimbursed
draws on any Letters of Credit.

          The commitment fees provided in this Paragraph 2.11 shall apply from
and after the Effective Date, and Borrower shall pay to CoreStates on the
Effective Date all accrued and unpaid commitment fees to and including the
Effective Date in accordance with the Existing Credit Agreement.

          2.12.  Closing Fee.  On the date of execution of this Agreement,
                 -----------                                              
Borrower shall pay (i) to each Existing Bank, a fee equal to (A) one-eighth of
one percent (1/8%) of such Bank's aggregate Maximum Principal Amount up to such
Bank's aggregate Maximum Principal Amount under the Existing Agreement (which
shall not include, in the case of CoreStates, the Bridge Commitment established
pursuant to Amendment No. 2 to the Existing Agreement), plus (B) one-quarter of
one percent (1/4%) of the amount of such Bank's aggregate Maximum Principal
Amount in excess of such Bank's Maximum Principal Amount under the Existing
Agreement, and (ii) to each Bank that is not an Existing Bank, a fee equal to
one-quarter of one percent (1/4%) of such Bank's aggregate Maximum Principal
Amount.

          2.13.  Agent's Fees.  Borrower shall pay to Agent fees as agreed
                 ------------                                             
between Borrower and Agent pursuant to the Summary Terms and Conditions dated
February 5, 1997.

          2.14.  Regulatory Changes in Capital Requirements.  If any Bank shall
                 ------------------------------------------                    
have determined that the adoption or the effectiveness after the date hereof of
any law, rule, regulation or guideline regarding capital adequacy, or any change
in any of the foregoing or in the interpretation or administration of any of the
foregoing by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by such
Bank (or any lending office of such Bank) or such Bank's holding company with
any request or directive regarding capital adequacy (whether or not having the
force of law) of any such authority, central bank or comparable agency, has or
would have the effect of reducing the rate of return on such Bank's capital or
on the capital of such Bank's holding company, as a consequence of this
Agreement, the Commitment, Advances or the Loan made by such Bank pursuant
hereto to a level below that which such Bank or its holding company could have
achieved but for such adoption, change or compliance (taking into consideration
such Bank's policies and the policies of such Bank's holding company with
respect to capital adequacy) by an amount deemed by such Bank to be material,
then from time to time Borrower shall pay to such Bank 

                                      -31-
<PAGE>
 
such additional amount or amounts as will compensate such Bank or its holding
company for any such reduction suffered together with interest on each such
amount from the date demanded until payment in full thereof at the rate provided
in Paragraph 2.6(b)(ii) hereof with respect to amounts not paid when due. Such
Bank will notify Borrower of any event occurring after the date of this
Agreement that will entitle such Bank to compensation pursuant to this Paragraph
2.14 as promptly as practicable after it obtains knowledge thereof and
determines to request such compensation, and such compensation shall not be
charged for any period more than three (3) months prior to the date of such
notice.

          A certificate of such Bank setting forth such amount or amounts as
shall be necessary to compensate such Bank or its holding company as specified
above shall be delivered to Borrower and shall be conclusive absent manifest
error, if calculated and charged in a manner consistent with similar charges
made by such Bank to its other customers having similar arrangements with such
Bank.  Borrower shall pay such Bank the amount shown as due on any such
certificate delivered by such Bank within ten (10) days after its receipt of the
same.

          Failure on the part of any Bank to demand compensation for increased
costs or reduction in amounts received or receivable or reductions in return on
capital with respect to any period shall not constitute a waiver of such Bank's
right to demand compensation with respect to any other period except as
otherwise limited by the terms of this Paragraph 2.14.

                                  SECTION 2A

                               LETTERS OF CREDIT
                               -----------------

          2A.1.  Availability of Credits.  Subject to the terms and conditions
                 -----------------------                                      
set forth herein, Banks shall from time to time prior to the Revolving
Commitment Termination Date participate in the issuance by Agent of Letters of
Credit for the account of Borrower on the following terms and conditions:

          (a) at the time of issuance of the Letter of 

                                      -32-
<PAGE>
 
Credit, the unborrowed portion of the Revolving Commitment shall equal or exceed
the sum of the amount available to be drawn under such Letter of Credit and all
other Letters of Credit then outstanding hereunder plus any unreimbursed draws
under Letters of Credit;

          (b) at the time of issuance of the Letter of Credit, the amount
available to be drawn under such Letter of Credit and all other Letters of
Credit then outstanding hereunder plus any unreimbursed draws under Letters of
Credit shall not exceed, in the aggregate, the Letter of Credit Sublimit;

          (c) the final expiration date of each Letter of Credit shall be on or
before the earlier of (i) one year from the date of issuance thereof or (ii) the
Revolving Commitment Termination Date;

          (d) there shall not exist at the time of issuance of the Letter of
Credit, and as a result thereof, any Default or Event of Default; and

          (e) each Letter of Credit issued under this Section 2A shall be
utilized by a Company in the ordinary course of its business or in connection
with a Permitted Acquisition.

          Upon issuance of each Letter of Credit, each Bank shall have a
participation interest therein based on its percentage share of the Revolving
Commitment as set forth in Schedule 1 attached to the Credit Agreement.

          2A.2.  Commitment Availability.  The amount available under the
                 -----------------------                                 
Revolving Commitment as from time to time in effect shall be reduced by the
amount available to be drawn under all outstanding Letters of Credit and
unreimbursed amounts of any draws under Letters of Credit.  The amount by which
the Revolving  Commitment is so reduced shall not be available for advances
under Paragraph 2.7 hereof, except advances thereunder which are made to
reimburse Agent for draws under the Letters of Credit as permitted pursuant to
Paragraph 2A.4(b) hereof.

          2A.3.  Approval and Issuance.
                 --------------------- 

          (a) Borrower shall provide Agent not less than three (3) Business
Days' prior written notice of each request for the issuance of a Letter of
Credit by delivery of a Letter of Credit Request Form and Agent's Letter of
Credit Application in the form attached as Exhibit B-2 hereto.  Each Letter of
Credit Request Form submitted by Borrower to Agent requesting the issuance of a
Letter of Credit shall be certified by the chief financial officer or chief
executive officer of Borrower, on behalf of Borrower and the applicable Company
for whose benefit 

                                      -33-
<PAGE>
 
the Letter of Credit is to be issued, and shall, in addition to the matters
described in Paragraph 2.7(a) hereof, list all Letters of Credit outstanding for
the account of Borrower at that time and, for each Letter of Credit so listed,
its face amount, outstanding undrawn balance and expiration date. It shall be a
condition to the issuance of any Letter of Credit that Agent shall have received
a Letter of Credit Request Form as described above and that the conditions set
forth in Paragraph 4.2 shall be satisfied.

          (b) Agent will promptly provide to Banks written or telephonic
notification of Agent's receipt of the Letter of Credit Request Form and the
Letter of Credit Application which shall state (i) the amount of the Letter of
Credit requested and (ii) the expiration date of the requested Letter of Credit.

          2A.4.  Obligations of the Borrower.
                 --------------------------- 

          (a) Borrower agrees to pay to Agent in connection with each Letter of
Credit issued hereunder:  (i) immediately upon the demand of Agent on behalf of
all Banks, the amount paid by Agent or any Bank with respect to such Letter of
Credit; (ii) immediately upon demand of Agent, the amount of any draft presented
purporting to be drawn under such Letter of Credit provided that the draft and
accompanying documents conform to the terms of the Letter of Credit but subject
to the terms of Paragraph 2A.7 (whether or not Agent has at such time honored
such draft) and any other amounts paid thereunder (it being understood that
Agent is not required to make demand upon or proceed against any Bank or other
party or to resort to any Collateral before obtaining payment from Borrower);
(iii) quarterly in arrears on the first day of each June, September, December
and March, a fee for the benefit of Banks in accordance with each Bank's Pro
Rata Share of the Revolving Commitment, calculated on the outstanding face
amount and term of such Letter of Credit at a rate per annum equal to the
Applicable Margin for a Portion bearing interest based on the Adjusted Libor
Rate, as set forth in Paragraph 2.6 hereof, as in effect upon the issuance or
renewal of the Letter of Credit, as applicable; (iv) on the date of issuance of
each Letter of Credit and on the effective date of any renewal or extension of
any Letter of Credit a fee of one-eighth of one percent (0.125%) per annum on
the outstanding face amount of such Letter of Credit, payable to Agent for its
own account, and (v) interest on any indebtedness outstanding with respect to
such Letter of Credit, whether for funds paid on drafts on such Letter of
Credit, or otherwise (but such indebtedness shall not include undrawn balances
of such Letter of Credit issued hereunder) at the rate set forth in Paragraph
2.6(b)(i)(A) hereof from the date of payment by Agent (if not reimbursed by
Borrower on the same day) to the date one (1) Business Day after notice to
Borrower of such payment, and 

                                      -34-
<PAGE>
 
thereafter at the rate applicable to Portions bearing interest based on the Base
Rate under Paragraph 2.6(b)(ii) hereof. Interest under the preceding clause (v)
shall be paid at the times and in the manner set forth in Paragraph 2.6 hereof,
and shall accrue on amounts paid on a Letter of Credit (if not reimbursed by
Borrower on the same day) from the date of payment by Agent, whether or not
demand is made, until such amounts are reimbursed by Borrower whether before, at
or after demand.

          (b) On or before the Revolving Commitment Termination Date, in the
absence of a Default or Event of Default at such time, and subject to the
provisions of Paragraph 2.7 hereof, Banks severally hereby agree to advance
funds to Borrower under the Revolving Loan to make the payments required under
Paragraphs 2A.4(a)(i) and (ii) hereof.  If any payment by the Agent of a draft
drawn under a Letter of Credit is for any reason (including without limitation
the occurrence or continuation of a Default or Event of Default hereunder) not
reimbursed prior to or on the date of such payment, the amount of such payment
shall thereupon be deemed for purposes hereof an advance under Paragraph 2.7
hereof.  Such reimbursement obligation shall be repayable, prepayable, and
otherwise subject to all the terms and conditions thereof as if advanced by
Banks pursuant to Paragraph 2.7 hereof (but without duplication).

          2A.5.  Payment by Banks on Letters of Credit.
                 ------------------------------------- 

          (a) With respect to each Letter of Credit issued hereunder, each Bank
agrees that it is irrevocably obligated to pay to Agent, for each such Letter of
Credit, such Bank's Pro Rata Share of each and every payment made or to be made
by Agent under such Letter of Credit (each such payment to be made, a "LOC
Contribution").  Each Bank's LOC Contribution shall be due from such Bank
immediately upon, and in any event no later than the same day as, receipt of
written notice (which may be sent by telex or telecopier) from Agent (except
that if such notice is received after 3:00 p.m. on any Business Day, payment may
be made on the following Business Day, together with interest equal to the
effective rate for overnight funds in New York as reported by the Federal
Reserve Bank of New York for such day (or, if such day is not a Business Day,
for the next preceding Business Day))  that (i) it has made a payment or (ii) a
draft has been presented purporting to be drawn on a Letter of Credit issued
hereunder.  Such payment shall be made at Agent's offices in immediately
available federal funds.

          (b) The obligation of each Bank to make its LOC Contribution hereunder
is absolute, continuing and unconditional, and Agent shall not be required first
to make demand upon or proceed against Borrower or any guarantor or surety, or
any others liable with respect to the applicable Letter of Credit and 

                                      -35-
<PAGE>
 
shall not be required first to resort to any Collateral. LOC Contributions shall
be made without regard to termination of this Agreement or the Commitments, the
existence of an Event of Default or Default hereunder, the acceleration of
indebtedness hereunder or any other event or circumstance.

          2A.6.  Collateral Security.
                 ------------------- 

          (a) The indebtedness, liabilities and obligations of Borrower under
this Section 2A, however created or incurred, whether now existing or hereafter
arising, due or to become due, absolute or contingent, direct or indirect,
secured or unsecured, are among the obligations secured by the security
interests, liens and encumbrances created by the Collateral, and Agent and the
Banks are entitled to the benefit of the Collateral granted thereunder with
respect to such indebtedness.

          (b) Notwithstanding the payment in full of the Loan, the termination
of the Commitments or the occurrence of the Termination Date, the Collateral
shall continue to secure the indebtedness, liabilities and obligations of
Borrower under this Section 2A until all Letters of Credit shall have expired
and all indebtedness, liabilities and obligations under this Section 2A shall
have been paid in full.

          (c) On the termination of the Revolving Commitment or the occurrence
of an Event of Default, Required Banks may require (and in the case of an Event
of Default occurring under Paragraph 8.1(i) it shall be required automatically)
that Borrower deliver to Agent cash or U.S. Treasury Bills with maturities of
not more than 90 days from the date of delivery (discounted in accordance with
customary banking practice to present value to determine amount) in an amount
equal at all times to one hundred ten percent (110%) of the outstanding undrawn
amount of all Letters of Credit, such cash or U.S. Treasury Bills and all
interest earned thereon to constitute cash collateral for all such Letters of
Credit.  At such time as such collateral is required to be and has not been
deposited, Agent on behalf of Banks shall be entitled to liquidate such of the
other collateral for the Loan (if any) as is necessary or appropriate in its
sole judgment so as to create such cash collateral.

          (d) Any cash collateral deposited under subparagraph (c) above, and
all interest earned thereon, shall be held by Agent and invested and reinvested
at the expense and the written direction of Borrower, in U.S. Treasury Bills
with maturities of no more than ninety (90) days from the date of investment.

          2A.7.  General Terms of Credits.  The following terms and conditions
                 ------------------------                                     
apply with respect to each Letter of Credit (a 

                                      -36-
<PAGE>
 
"Credit") notwithstanding anything to the contrary contained herein:

          (a) Borrower assumes all risks of the acts or omissions of the
beneficiary of each Credit with respect to the use of the Credit or with respect
to the beneficiary's obligations to Borrower.  None of the Banks nor any of
their officers or directors shall be liable or responsible for, and the Banks
hereby agree to indemnify and hold Agent and any issuer of a Credit harmless
(except for the issuer's gross negligence or willful misconduct) with respect
to:  (i) the use which may be made of the Credit or for any acts or omissions of
the beneficiary in connection therewith; (ii) the accuracy, truth, validity,
sufficiency or genuineness of documents, or of any endorsement thereon, even if
such documents should in fact prove to be in any or all respects false,
misleading, inaccurate, invalid, insufficient, fraudulent, or forged; (iii) the
payment by Agent against presentation of documents which do not comply with the
terms of the Credit, including failure of any documents to bear any reference or
adequate reference to a Credit; (iv) any other circumstances whatsoever in
making or failing to make payment under a Credit; or (v) any inaccuracy,
interruption, error or delay in transmission or delivery of correspondence or
documents by post, telegraph or otherwise.  In furtherance and not in limitation
of the foregoing, Agent may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary.

          (b) Notwithstanding the foregoing, with respect to any Credit,
Borrower shall have a claim against Agent, and Agent shall be liable to
Borrower, to the extent, but only to the extent, of any direct, as opposed to
indirect or consequential, damages suffered by Borrower caused by the Agent's
willful misconduct or gross negligence.

          (c) To the extent not inconsistent with this Agreement, the Uniform
Customs and Practices for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500, are hereby made a part of this
Agreement with respect to obligations in connection with each Credit.

                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

          Borrower represents and warrants to Banks as follows:

          3.1.  Organization and Good Standing.  Each of the Companies is a

corporation or limited partnership, duly formed and validly existing under the
laws of its state of formation, and has the power and authority to carry on its

otherwise set forth on Exhibit F attached hereto:

Effect, each Company (i) has received all permits and filed all notifications
required by the Environmental Control Statutes to carry on its respective
business(es); and (ii) is in compliance with all Environmental Control Statutes.

          (b) Each Company has given any written or oral notice to the EPA or
any state or local agency with regard to any actual or imminently threatened
Release of Hazardous Substances on properties owned, leased or operated by such
Company or used in connection with the conduct of its business and operations
which is reasonably likely to have a Material Adverse Effect.

          (c) No Company has received notice that it is potentially responsible
for clean-up, remediation, costs of clean-up or remediation, fines or penalties
with respect to any actual or imminently threatened Release of Hazardous
Substances pursuant to any Environmental Control Statute which is reasonably

                 --------                                                     
intercompany indebtedness, each Company is, and after receipt and application of
the first Advance under this Agreement will be, solvent such that (i) the fair
value of its assets (including without limitation the fair salable value of the
goodwill and other intangible property of such Company) is greater than the
total amount of its liabilities, including 

                                      -42-
<PAGE>
 
without limitation, contingent liabilities, (ii) the present fair salable value
of its assets (including without limitation the fair salable value of the
goodwill and other intangible property of such Company) is not less than the
amount that will be required to pay the probable liability on their debts as
they become absolute and matured, and (iii) they are able to realize upon their
assets and pay their debts and other liabilities, contingent obligations and
other commitments as they mature in the normal course of business. No Company
intends to, nor believes that it will, incur debts or liabilities beyond its
ability to pay as such debts and liabilities mature, and no Company is engaged
in a business or transaction, or about to engage in a business or transaction,
for which its property would constitute unreasonably small capital after giving
due consideration to the prevailing practice and industry in which it is
engaged. For purposes of this Paragraph 3.18, in computing the amount of
contingent liabilities at any time, it is intended that such liabilities will be
computed at the amount which, in light of all the facts and circumstances
existing at such time, represents the amount that reasonably can be expected to
become an actual matured liability of the applicable Company.

          Each Company hereby agrees that to the extent a Company shall have
paid more than its proportionate share of any payment made hereunder or under
the Guaranty, such Company shall be entitled to seek and receive contribution
from and against any other Company who has not paid its proportionate share of
such payment; provided however such Company shall not seek any such contribution
from any other Company until the Loans have been paid in full and all
Commitments of the Banks hereunder have been terminated.  The provisions of this
paragraph shall in no respect limit the obligations and liabilities of any
Company to the Agent and the Banks and each Company shall remain liable to the
Agent and the Banks for the full amount of its obligations hereunder and under
the Guaranty.

          3.19.  Employee Controversies.  There are no material controversies
                 ----------------------                                      
pending or, to the knowledge of the Companies, threatened or anticipated between
any Company and any of its respective employees, and there are no labor
disputes, grievances, arbitration proceedings or any strikes, work stoppages or
slowdowns pending, or to the Companies' knowledge, threatened between any
Company and its respective employees and representatives, which in either event
could impair the ability of the Company to perform their obligations under the
Loan Documents, or which might reasonably be expected to have a Material Adverse
Effect.

          3.20.  Inactive Subsidiaries.  There does not exist, by virtue of
                 ---------------------                                     
statute, common law, contract or otherwise, any liability of, or any activity or
condition relating to, any 

                                      -43-

Inactive Subsidiary, including, without limitation, with respect to any
environmental condition, taxes, employee benefit plan, program or statutory
obligation, tort claim or contract dispute, which may survive the liquidation of
any such Inactive Subsidiary (whether by operation of law, express assumption or
otherwise), except for those liabilities which (a) are reserved for or otherwise
reflected in the financial statements of Parent and its consolidated
Subsidiaries or (b) do not in the aggregate as to all Inactive Subsidiaries

of any and all of Borrower's indebtedness and obligations to Banks, whether
matured or unmatured, now existing or hereafter incurred or created hereunder or
otherwise, Borrower hereby grants to Banks a security interest in and lien upon

          This Section sets forth the relative rights and duties of Agent and
Banks respecting the Loan and, with the exception of Paragraphs 9.3 and 9.15
hereof, does not confer any enforceable rights on Borrower against Banks or
create on the part of Banks any duties or obligations to Borrower.

          9.1.  Application of Payments.  Agent shall apply all payments of
                -----------------------

or on behalf of Borrower with respect to the Revolving Loan, RSD Loan, LHS Loan,

payments shall be made promptly in federal funds immediately available at the
office of each Bank set forth above.

          9.2.  Set-Off.  In the event a Bank, by exercise of its right of set-
                -------                                                       
off, or otherwise, receives any payment of principal or interest, in an amount
greater than its Pro Rata Share of such payment based upon the Banks' respective
shares of principal Indebtedness outstanding hereunder immediately before such
payment, such Bank shall purchase a portion of the Indebtedness hereunder owing
to each other Bank so that after such purchase each Bank shall hold its Pro Rata
Share of all the Indebtedness then outstanding hereunder, provided that if all
or any portion of such excess payment is thereafter recovered from such Bank,
such purchase shall be rescinded and the purchase price restored to the extent
of any such recovery, but without interest.

          9.3.  Modifications and Waivers.  No modification or amendment hereof,
                -------------------------                                       
consent hereunder or waiver of any Event of Default shall be effective except by

consent of all Banks shall be required to (i) modify, amend, waive, discharge,
terminate or suspend compliance with (A) any rate of interest applicable to the
Revolving Loan, RSD Loan, LHS Loan,  or Acquisition Loan, to the extent it is

          9.4.  Obligations Several.  The obligations of the Banks hereunder are
                -------------------                                             
several, and each Bank hereunder shall not be responsible for the obligations of
the other Banks hereunder, nor will the failure of one Bank to perform any of
its obligations hereunder relieve the other Banks from the performance of their
respective obligations hereunder.

          9.5.  Banks' Representations.  Each Bank represents and warrants to
                ----------------------                                       
the other Banks that (i) it has been furnished all information it has requested
for the purpose of evaluating its proposed participation under this Agreement;
and (ii) it has decided to enter into this Agreement on the basis of its
independent review and credit analysis of Borrower, this Agreement and the
documentation in connection therewith and has not relied for such analysis on
any information or analysis provided by any other Bank.

          9.6.  Investigation.  No Bank shall have any obligation to the others
                -------------                                                  
to investigate the condition of Borrower or any of the Collateral or any other
matter concerning the Loan.

          9.7.  Powers of Agent.  Agent shall have and may exercise those powers
                ---------------                                                 
specifically delegated to Agent herein, together with such powers as are
reasonably incidental thereto.

          9.8.  General Duties of Agent, Immunity and Indemnity.  Upon receipt
                -----------------------------------------------               
of notices and reports delivered by Borrower to the Agent under this Agreement,
the Agent shall promptly deliver the same in the form received to the Banks.
Required Banks shall also have the right to request Agent to inspect Borrower's
books and records and take the other steps provided in Paragraph 5.8 hereof.  In
performing its duties as Agent hereunder, Agent will take the same care as it
takes in connection with loans in which it alone is interested, subject to the
limitations on liabilities contained herein; provided that Agent shall not be
obligated to ascertain or inquire as to the performance of any of the terms,
covenants or conditions hereof by Borrower.  Neither Agent nor any of its
directors, officers, agents or employees shall be liable for any action or
omission by any of them hereunder or in connection herewith except for gross
negligence or willful misconduct.  Subject to such exception, each of the Banks
hereby indemnifies Agent (in its capacity as Agent) on the basis of such Bank's
Pro Rata Share, against any liability, claim, loss or expense arising from or
relating to any action taken or omitted to be taken with respect to this
Agreement, any other Loan Document or the transactions contemplated thereby or
Borrower, to the extent that the Agent has not been reimbursed therefor by
Borrower, without affecting any obligation of Borrower to reimburse.

<PAGE>
 
          9.9.  No Responsibility for Representations or Validity, etc.  Each
                ------------------------------------------------------       
Bank agrees that Agent shall not be responsible to any Bank for any
representations, statements, or warranties of Borrower herein.  Neither Agent
nor any of its directors, officers, employees or agents shall be responsible for
the validity, effectiveness, sufficiency, perfection or enforceability of this
Agreement and any Collateral, or any documents relating thereto or for the
priority of any of Banks' security interests in any such Collateral.

          9.10.  Action on Instruction of Banks; Right to Indemnity.  Agent
                 --------------------------------------------------        
shall act upon written instruction of Banks or Required Banks, as appropriate,
and in all cases Agent shall be fully protected in acting or refraining from
acting hereunder in accordance with such written instructions to it signed by
Required Banks unless the consent of all the Banks is expressly required
hereunder in which case Agent shall be so protected when acting in accordance
with such instructions from all the Banks.  Such instructions and any action
taken or failure to act pursuant thereto shall be binding on all the Banks,
provided that except as otherwise provided herein, Agent may act hereunder in
its own discretion without requesting such instructions.

          9.11.  Employment of Agents.  In connection with its activities
                 --------------------                                    
hereunder, Agent may employ agents and attorneys-in-fact and shall not be
answerable, except as to money or securities received by it or its authorized
agents, for the default or misconduct of agents or attorneys-in-fact selected
with reasonable care.

          9.12.  Reliance on Documents.  Agent shall be entitled to rely upon
                 ---------------------                                       
(a) any paper or document believed by it to be genuine and correct and to have
been signed or sent by the proper person or persons and (b) upon the opinion of
its counsel with respect to legal matters.

          9.13.  Agent's Rights as a Bank.  With respect to its share of the
                 ------------------------                                   
indebtedness hereunder, Agent shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not Agent.  Each of
the Banks may accept deposits from and generally engage in other banking or
trust business with Borrower as if it were not Agent or a Bank hereunder.

          9.14.  Expenses.  Each of the Banks shall reimburse Agent, from time
                 --------                                                     
to time at the request of Agent, for its Pro Rata Share of any expenses incurred
by Agent in connection with the performance of its functions hereunder without
affecting any obligation of Borrower to reimburse, provided however that in the
event Banks shall reimburse Agent for expenses for which Borrower subsequently
reimburses Agent, Agent shall remit to each Bank the 

                                      -65-
<PAGE>
 
respective amount received from such Bank against such expenses.

          9.15.  Resignation of Agent.  Agent may at any time resign its
                 --------------------                                   
position as Agent, without affecting its position as a Bank, by giving written
notice to Banks and Borrower.  Such resignation shall take effect upon the
appointment of a successor agent in accordance with this Paragraph 9.15.  In the
event Agent shall resign, Required Banks with the consent of Borrower, which
consent will not be unreasonably withheld, shall appoint a Bank as successor
agent.  If within thirty (30) days of the Agent's notice of resignation no
successor agent shall have been appointed by Banks and accepted such
appointment, then Agent, in its discretion may appoint any other Bank with
banking powers as a successor agent.

          9.16.  Successor Agent.  The successor Agent appointed pursuant to
                 ---------------                                            
Paragraph 9.15 shall execute and deliver to its predecessor and Banks an
instrument in writing accepting such appointment, and thereupon such successor,
without any further act, deed or conveyance, shall become fully vested with all

          10.1.  Indemnification and Release Provisions.  Borrower hereby agrees
                 --------------------------------------

and counsel from, and hold each of them harmless against, any and all losses,
liabilities (including without limitation settlement costs and amounts, transfer
taxes, documentary taxes, or assessments or charges made by any governmental
authority), claims, damages, interest judgments, costs, or expenses, including
without limitation reasonable fees and disbursements of counsel, incurred by any
of them arising out of or in connection with or by reason of this Agreement, the
Commitment, the making of the Loan or any Collateral therefor, other than those

any and all claims for loss, damages, costs or expenses caused or alleged to be
caused by any act or omission on the part of any of them other than those
resulting primarily from any such party's own wilful misconduct or gross
negligence.  All obligations provided for in this Paragraph 10.1 shall survive
any termination of this Agreement or the Commitment and the repayment of the
Loan.

          10.2.  Participations and Assignments.  Borrower hereby acknowledges
                 ------------------------------                               
and agrees that a Bank may at any time:  (a) grant participations in all or any
portion of its Maximum Principal Amount of the Loan or of its right, title and
interest therein or in or to this Agreement (collectively, "Participations") to
any other lending office or to any other bank or lending institution
("Participants"); provided, however, that:  (i) all amounts payable by Borrower
hereunder shall be determined as if such Bank had not granted such
Participation; and (ii) any agreement pursuant to which any Bank may grant a
Participation:  (x) shall provide that such Bank shall retain the sole right and
responsibility to enforce the obligations of Borrower hereunder including,
without limitation, the right to approve any amendment, modification or waiver
of any provisions of this 

                                      -67-
<PAGE>
 
Agreement; (y) may provide that such Bank will not agree to any modification,
amendment or waiver of this Agreement without the consent of the Participant if
such modification, amendment or waiver would require approval of all Banks
pursuant to Paragraph 9.3 hereof; and (z) shall not relieve such Bank from its
obligations, which shall remain absolute, to make Advances hereunder; and (b)
assign its rights and obligations under the Commitment and the Loan with notice
to Borrower and Agent together with the payment to Agent of a $2,500 transfer
fee, provided, that in the absence of an Event of Default hereunder no Bank
shall assign more than fifty percent (50%) of its rights and obligations
hereunder. Any grant of a participation or assignment pursuant to this Paragraph
10.2 shall be pro rata as to the Acquisition Loan and the Revolving Loan.
Borrower may not assign or otherwise its rights or obligation under this
Agreement without the prior written consent of Banks.

          10.3.  Binding and Governing Law.  This Agreement and all documents
                 -------------------------                                   
executed hereunder shall be binding upon and shall inure to the benefit of the
parties hereto and their respective successors and assigns and, except as may be
required by mandatory provisions of applicable law, shall be governed as to
their validity, interpretation and effect by the laws of the Commonwealth of
Pennsylvania.

          10.4.  Survival.  All agreements, representations, warranties and
                 --------                                                  
covenants of Borrower contained herein or in any documentation required
hereunder shall survive the execution of this Agreement and the making of the
Loan hereunder, and except for Paragraphs 5.12 and 10.1 which provide otherwise
will continue in full force and effect as long as any indebtedness or other
obligation of Borrower to Banks remains outstanding.

          10.5.  No Waiver; Delay.  If Banks shall waive any power, right or
                 ----------------                                           
remedy arising hereunder or under any applicable law, such waiver shall not be
deemed to be a waiver upon the later occurrence or recurrence of any of said
events with respect to Banks.  No delay by Banks in the exercise of any power,
right or remedy shall, under any circumstances, constitute or be deemed to be a
waiver, express or implied, of the same and no course of dealing between the
parties hereto shall constitute a waiver of Banks' powers, rights or remedies.
The remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

          10.6.  Modification; Waiver.  Except as otherwise provided in this
                 --------------------
