conditions hereof and relying upon the representations and warranties herein set
forth, that the Borrower shall have the right to borrow, repay and reborrow,
from the date hereof until the Revolving Credit Termination Date, a principal
amount not to exceed Thirteen Million Dollars ($13,000,000) in the aggregate at
any one time outstanding.

2.1b      Voluntary Reductions of Revolving Credit Commitment; Voluntary

              --------------------                                            
the Bank, the Borrower may from time to time voluntarily permanently reduce the
Revolving Credit Commitment.  Each voluntary reduction shall be in a minimum
amount of $500,000 or, if greater than $500,000, in integral multiples of
$100,000.

          (ii) Effect of Reductions.  Simultaneously with each voluntary
               --------------------                                     
permanent reduction, the Borrower shall make a payment of the outstanding
Revolving Credit Loans equal to the excess, if any, of (A) the aggregate
principal amount of the outstanding Revolving Credit Loans over (B) the
Revolving Credit Commitment, as so reduced.  Notice of a reduction, once given,
shall be irrevocable.  All such reductions shall be without penalty or premium
(except for amounts owing pursuant to Section 2.2e(iv), if any).

          (iii)  Application of Reductions and Payments.  Any principal payments
                 --------------------------------------                         
shall be accompanied by all accrued and unpaid interest thereon, all amounts due
pursuant to Section 2.2, if any, and, in the case of a permanent reduction of
the Revolving Credit Commitment to zero, any other outstanding Obligations which
are then due and payable.  All such payments shall be applied by the Bank to

$500,000, or if in excess of $500,000, in integral multiples of $100,000.



                                     -12-

 
2.1d      Repayment On Revolving Credit Termination Date.  On the Revolving

2.1e      Revolving Credit Note.  The obligation of the Borrower to repay, on or
          ---------------------

amount of the Revolving Credit Loans shall be evidenced by a Revolving Credit
Note, substantially in the form of Exhibit "A", (i) drawn by the Borrower to the
                                   -----------                                  
order of the Bank in the maximum amount of the Revolving Credit Commitment, (ii)
duly executed by the Borrower and (iii) delivered to the Bank.  The principal
amount actually due and owing the Bank under the Revolving Credit Note shall be

Bank, all as shown on the Loan Accounts established pursuant to Section 2.6.

2.2       Interest.
          -------- 

2.2a      Interest Rates.
          -------------- 

          Revolving Credit Loans.  During the term hereof the Borrower, in
          ----------------------                                          
accordance with the provisions of this Section 2.2, shall have the option of
electing from time to time one or more of the Interest Rate Options to be
applied by the Bank to outstanding Revolving Credit Loans, as follows:  interest
(i) under the Base Rate Option shall accrue at a rate per annum equal to the
Base Rate, and (ii) under the Euro-Rate Option shall accrue at a rate per annum
equal to the sum of (A) the Euro-Rate plus (B) one-half of one percent (50 basis
points).

2.2b      Adjustments to Interest Rates.
          ----------------------------- 

          (i) Changes in Base Rate.  The Base Rate Option shall be adjusted from
              --------------------                                              
time to time, without notice to the Borrower, as necessary to reflect any
changes in the Base Rate, which adjustments shall be automatically effective on
the day of any such change.

          (ii) Changes in Euro-Rate Reserve Percentage.  The Euro-Rate shall be
               ---------------------------------------                         
adjusted from time to time, with respect to Revolving Credit Loans, without
notice to the Borrower, as necessary to reflect any changes in the Euro-Rate
Reserve Percentage, which adjustments shall be automatically effective on the
day of such change.

          (iii)  Event of Default.  Upon the occurrence of and during the
                 ----------------                                        
continuance of an Event of Default, (A) the outstanding principal amount of all
Revolving Credit Loans shall bear interest from the date of such occurrence at a
rate per annum which is equal to the sum of the Base Rate plus one percent (1%).



                                     -13-

 
          (iv) Notice of Changes.  The Bank, consistent with its then current
               -----------------                                             
business practices, will notify the Borrower of any changes of rates set forth
in items (i), (ii) and (iii) above which notice, in all cases, will be after
such changes become effective.  Failure of the Bank to notify the Borrower of
any such change shall not impair the validity of any such rate change.

2.2c      Interest Rate Option Elections, Renewals and Conversions.  Subject to
          --------------------------------------------------------             
the remaining provisions of this Agreement, the Borrower shall have the option
to elect to have all or any Revolving Credit Loans bear interest at either of
the Interest Rate Options and shall have the right to renew elections of
Interest Rate Options and convert Revolving Credit Loans to other Interest Rate
Options.  Notice of the Borrower's election shall be made in accordance with
Section 2.4.  Elections of, conversions to or renewals of the Base Rate Option
shall continue in effect until converted to the Euro-Rate Option.  Elections of,
conversions to or renewals of the Euro-Rate Option shall expire as to each such
Euro-Rate Option at the expiration of the applicable Euro-Rate Interest Period.
Any Revolving Credit Loans outstanding for which no elections have been made
shall bear interest under the Base Rate Option.

2.2d      Limitation on Election of Euro-Rate Options.  Each election of the
          -------------------------------------------                       
Euro-Rate Option or the prepayment of all or any Euro-Rate Loans shall be in the
minimum principal amount of $500,000 or, if in excess of $500,000, in integral
multiples of $100,000.  At no time during the term hereof may there be more than
a total of five (5) separate Euro-Rate Interest Periods in effect; provided,
                                                                   -------- 
however, if the Borrower is borrowing under the Base Rate Option there may be no
- -------                                                                         
more than a total of four (4) separate Euro-Rate Options in effect.  Upon the
occurrence and during the continuance of an Event of Default, the Borrower's
right to elect, renew or convert to Euro-Rate Loans shall be suspended.

2.2e      Special Provisions Relating to Euro-Rate Option.
          ----------------------------------------------- 

          (i) Euro-Rate Unascertainable.  In the event that on any date on which
              -------------------------                                         
a Euro-Rate would otherwise be set the Bank shall have determined in good faith
(which determination shall be final and conclusive) that, by reason of
circumstances affecting the London interbank market, adequate and reasonable
means do not exist for ascertaining the Euro-Rate, the Bank shall give prompt
notice of such determination to the Borrower and until the Bank notifies the
Borrower that the circumstances giving rise to such determination no longer
exist, the right of the Borrower to borrow under, renew or convert to the Euro-
Rate Option shall be treated as a request to borrow under, renew or convert to
the Base Rate Option.

          (ii) Illegality of Offering Euro-Rate.  If the Bank shall determine in
               --------------------------------                                 
good faith, which determination shall be final and conclusive, that compliance
by the Bank with any applicable Governmental Rule (whether or not having the
force of law), or the interpretation or application thereof by any Governmental
Authority has made it unlawful for the Bank to make or maintain Euro-Rate Loans,
the Bank shall give notice of such determination to the Borrower.
Notwithstanding any provision of this Agreement to the



                                     -14-

 
contrary, unless and until the Bank shall give notice to the Borrower that the
circumstances giving rise to such determination no longer apply:

          (A) with respect to any Euro-Rate Interest Periods thereafter
commencing, interest on the corresponding Euro-Rate Loans shall be computed and
payable under the Base Rate Option; and

          (B) on such date, if any, as shall be required by law, any Euro-Rate
Loans then outstanding shall be automatically renewed at the Base Rate Option;
and the Borrower shall pay to the Bank the accrued and unpaid interest on such
Euro-Rate Loans to (but not including) such renewal date.

The Borrower shall pay the Bank any additional amounts reasonably necessary to
compensate the Bank (on an after-tax basis) for any out-of-pocket costs incurred
by the Bank as a result of any renewal pursuant to item (B) above on a day other
than the last day of the relevant Euro-Rate Interest Period, including, but not
limited to, any interest or fees payable by the Bank to lenders of funds
obtained by them to loan or maintain the Revolving Credit Loans so converted.
The Bank shall furnish to the Borrower a certificate showing the calculation of
the amount necessary to compensate the Bank (on an after-tax basis) for such
costs (which certificate, in the absence of manifest error, shall be
conclusive), and the Borrower shall pay such amount to the Bank, as additional
consideration hereunder, within ten (10) days of the Borrower's receipt of such
certificate.

          (iii)  Inability to Offer Euro-Rate.  In the event that the Bank shall
                 ----------------------------                                   
determine, in its sole discretion, that it is unable to obtain deposits in the
London interbank market in sufficient amounts and with maturities related to the
Euro-Rate Loans which would enable the Bank to fund such Euro-Rate Loans, then
the Bank shall immediately notify the Borrower that the right of the Borrower to
borrow under, convert to or renew the Euro-Rate Option shall be suspended.
Following notification of the suspension of the Euro-Rate Option, the Borrower
shall negotiate with the Bank for a modified Euro-Rate which will allow the Bank
to realize its anticipated and bargained-for yield.  In the event that the
Borrower and the Bank cannot agree on a modified Euro-Rate, any notice of
borrowing under, conversion to or renewal of the Euro-Rate Option which was to
become effective during the period of suspension shall be treated as a request
to borrow under, convert to or renew the Base Rate Option with respect to the
principal amount specified therein.

          (iv) Indemnity.  In addition to the other provisions of this Section
               ---------                                                      
2.2e, the Borrower hereby agrees to indemnify the Bank against any loss or
expense which the Bank may sustain or incur as a consequence of any default by
the Borrower in failing to make any borrowing, conversion or renewal hereunder
to bear interest at the Euro-Rate Option on the scheduled date, in failing to
make when due (whether by declaration, acceleration or otherwise) any payment of
any Euro-Rate Loan or in making any payment or prepayment of any Euro-Rate Loan
or any part thereof on any day other than the last day of the relevant Euro-Rate
Interest Period, including but not limited to any loss of profit, premium or
penalty incurred by the Bank in respect of funds borrowed by it for the purpose
of making or


                                     -15-

 
maintaining any Euro-Rate Loan as determined in good faith by the Bank in the
exercise of its sole but reasonable discretion.  The Bank shall furnish to the
Borrower a certificate showing the calculation of the amount of any such loss or
expense (which certificate, absent manifest error, shall be conclusive), and the
Borrower shall pay such amount to the Bank within ten (10) days of the
Borrower's receipt of such certificate.

2.2f      Yield Protection.  If any Governmental Rule or the interpretation or
          ----------------                                                    
application thereof by any court, any Governmental Authority charged with the
administration thereof or the compliance with any guideline or request from any
central bank or other Governmental Authority, whether or not having the force of
law:

          (i) subjects the Bank to any tax, levy, impost, charge, fee, duty,
deduction or withholding of any kind hereunder (other than any tax imposed or
based upon the income of the Bank and payable to any Governmental Authority or
taxing authority of the United States of America or any state thereof) or
changes the basis of taxation of the Bank with respect to payments by the
Borrower or principal, interest or other amounts due from the Borrower hereunder
(other than any change which affects, and to the extent that it affects, the
taxation by the United States of America or any state thereof of the total net
income of the Bank); or

          (ii) imposes, modifies or deems applicable any reserve, special
deposit, special assessment or similar requirements against assets held by,
deposits with or for the account of or credit extended by the Bank with respect
to loans to the Borrower (other than such requirements which are included in the
determination of the Euro-Rate hereunder); or

          (iii)  imposes upon the Bank any other condition with respect to this
Agreement;

and the result of any of the foregoing is to increase the cost to the Bank,
reduce the income receivable by the Bank, reduce the rate of return on the
Bank's capital or impose any expense upon the Bank by an amount which the Bank
in its sole but reasonable discretion deems to be material, the Bank shall from
time to time notify the Borrower of the amount determined by the Bank (which
determination, absent manifest error, shall be conclusive) to be reasonably
necessary to compensate the Bank (on an after-tax basis) for such increase in
cost, reduction in income, reduction in rate of return or additional expense,
and setting forth the calculations therefor.  The Borrower shall pay such amount
to the Bank, as additional consideration hereunder, within ten (10) days of the
Borrower' receipt of such notice from the Bank.

2.2g      Method of Calculation.  In determining the amount due the Bank
          ---------------------                                         
hereunder by reason of the application of this Section 2.2, the Bank may use any
reasonable averaging or attribution method; provided, however, that the Bank
                                            --------  -------               
must use reasonable efforts to minimize such losses and costs.



                                     -16-

 
2.2h      Interest Payment Dates.  Interest due on all outstanding Base Rate
          ----------------------                                            
Loans shall be payable quarterly in arrears on the last day of each calendar
quarter for the calendar quarter just ended, beginning on March 31, 1997.
Interest due on all outstanding Euro-Rate Loans and Base Rate Loans shall be
payable on the last day of each Euro-Rate Interest Period and, for Euro-Rate
Interest Periods of six months, also on the day which is three months after the
first day of such Euro-Rate Interest Period.  All accrued and unpaid interest on
the Revolving Credit Loans shall be due and payable on the Revolving Credit
Termination Date.  In addition, all accrued and unpaid interest on all of the
Obligations shall be due and payable after any maturity of the Note or the
Obligations, whether by acceleration or otherwise, on demand until all amounts
due hereunder are paid in full.

2.2i      Calculation of Interest.  Interest under the Base Rate Option shall be
          -----------------------                                               
calculated on the basis of the actual number of days elapsed, using a year of
365 or 366 days, as the case may be.  Interest under the Euro-Rate Option shall
be calculated on the basis of the actual number of days elapsed, using a year of
360 days.  Interest for any period shall be calculated from and including the
first day thereof to but not including the last day thereof.

2.3       Letter of Credit Commitment.
          --------------------------- 

2.3a      Issuance of Letters of Credit.  Subject to the further terms and
          -----------------------------                                   
conditions of this Agreement and in reliance upon the representations and
warranties set forth herein, the Bank agrees to issue upon the request of the
Borrower to the Bank, Letters of Credit for the account of the Borrower in an
aggregate Stated Amount not to exceed TWO MILLION FIVE HUNDRED THOUSAND AND
NO/100 DOLLARS ($2,500,000) at any one time outstanding (as may be increased or
reduced and reinstated from time to time in accordance with the terms and
provisions hereof).  The Stated Amount of each Letter of Credit, while the same
is issued and outstanding, shall be deducted from the maximum amount otherwise
available under the Revolving Credit Commitment.  By way of illustration, if
there are outstanding at any one time Letters of Credit having an aggregate
Stated Amount of $500,000, the maximum availability under the Revolving Credit
Commitment, without accounting for reductions which are a function of voluntary
permanent reductions, would be $12,500,000.  No Letters of Credit may be issued
hereunder to the extent the Stated Amount thereof would exceed the maximum
availability under the Revolving Credit Commitment (as may be reduced pursuant
to the terms of this Subsection 2.3a or Subsection 2.1b hereof).  No Letter of
Credit issued pursuant hereto shall have an initial term which exceeds twelve
(12) months from the date of issuance (except the Wouterson Letter of Credit)
nor have an expiry date later than fifteen (15) days prior to the Revolving
Credit Termination Date.  Prior to the issuance of any Letter of Credit
hereunder the Borrower shall complete and deliver to the Bank the Bank's then
current form of Application for Letter of Credit.  The issuance of each Letter
of Credit in accordance with the provisions of this Subsection 2.3a shall
require the satisfaction of each condition set forth in Sections 6.1 and 6.2
hereof.

2.3b      Limitation on Letters of Credit Commitment.    In the event any
          ------------------------------------------                     
restrictions are imposed upon the Bank by any Governmental Rule of any
Governmental


                                     -17-

 
Authority having jurisdiction over the banking activities of the Bank, which
would prevent the Bank from issuing a Letter of Credit or amending a Letter of
Credit the commitment of the Bank to issue the Letters of Credit or enter into
any amendment with respect thereto shall be immediately suspended.  The Bank
shall promptly notify the Borrower of the existence and nature of any
restriction which would cause the suspension of the commitment of the Bank to
issue any Letter of Credit or to enter into amendments with respect thereto. The
Borrower will thereupon undertake reasonable efforts to obtain the cancellation
of the Letters of Credit; provided, however, that the refusal of any beneficiary
                          --------  -------                                     
of the Letters of Credit to surrender such Letters of Credit will not be an
Event of Default hereunder and the Borrower shall undertake good faith efforts
to obtain a substitute letter of credit or letters of credit for the Letters of
Credit.  Nothing contained in this Subsection 2.3b shall be deemed a termination
of the Revolving Credit Commitment and, in the event of a suspension of the
commitment of the Bank to issue Letters of Credit as set forth above, the
Borrower may continue to borrow under the Revolving Credit Commitment provided
the requirements of Article VI hereof are complied with.

2.3c      Request for Amendments to Letters of Credit.  Whenever the Borrower
          -------------------------------------------                        
desires that the Bank enter into an amendment to a Letter of Credit, it shall
deliver to the Bank a written request no later than 11:00 A.M. (Pittsburgh,
Pennsylvania time) at least three (3) Business Days in advance of the proposed
date of such amendment.  The Bank shall have no obligation to consent to any
amendment to a Letter of Credit.  Any such amendment which may be so consented
to shall be effective only upon the satisfaction of the conditions set forth in
Article VI hereof.

2.3d      Payment of Amounts Drawn Under Letters of Credit.  Upon each request
          ------------------------------------------------                    
for a draw under a Letter of Credit by the beneficiary thereof, the Bank shall
immediately notify the Borrower and the Borrower shall reimburse, or cause the
reimbursement of, the Bank on demand in an amount in same day funds equal to the
amount of such draw; provided, however, that any failure of the Bank to notify
                     --------  -------                                        
the Borrower prior to honoring any such draw shall not affect the Borrower's
obligation to reimburse the Bank.  Unless the Borrower shall have notified the
Bank prior to such time that the Borrower intends to reimburse the Bank for all
or a portion of the amount of such draw with funds other than the proceeds of
Revolving Credit Loans, the Borrower shall conclusively be deemed to have given
a request for a Revolving Credit Loan under Section 2.4 hereof to the Bank
requesting the Bank to make Revolving Credit Loans at the Base Rate Option on
the first Business Day immediately following the date on which such draw is
honored in an aggregate amount equal to the excess of the amount of such draw
over the amount theretofore received by the Bank in reimbursement thereof (the
"Unreimbursed Amount"), plus accrued interest on such amount at the rate set
                        ----                                                
forth in Subsection 2.3e hereof.  If the Borrower shall be deemed to have given
a request for a Revolving Credit Loan under Section 2.4 hereof to the Bank
pursuant to this Subsection 2.3d, then, subject to satisfaction or waiver of the
conditions specified in Section 6.1 hereof, the Bank shall, on the first
Business Day immediately following the date of such draw, make Revolving Credit
Loans at the Base Rate Option in the aggregate amount of the Unreimbursed
Amount, plus accrued interest on such amount at the rate set forth in Subsection
        ----                                                                    
2.3e hereof.  The proceeds of any such Revolving Credit


                                     -18-

 
Loans shall be applied directly by the Bank, to reimburse the Bank for the
Unreimbursed Amount, plus accrued interest on such amount. The foregoing shall
                     ----                                                     
not limit or impair the obligation of the Borrower to reimburse the Bank on
demand for any Unreimbursed Amount.

          As to drafts or demands for payment under, or purporting to be under,
a Letter of Credit which are payable in currency other than Dollars, (i) on each
such draft, the equivalent of the amount paid at the rate of exchange then
current in New York, New York for wire transfers to the place of payment in the
currency in which such draft is drawn; and (ii) on each such demand for payment,
the equivalent of the demand for payment at the rate of exchange then current in
New York, New York for wire transfers to the place of payment in the currency in
which the demand for payment is payable, on demand and in any event not later
than the date for payment.  If for any reason whatsoever, there exists at the
time in question no rate of exchange generally current in New York, New York for
wire transfers of such currency, the Borrower agrees to pay the Bank on demand
in Dollars an amount equal to the actual cost of settlement of the Bank's
obligation to the payor of the draft or demands for payment or any holder
thereof, as the case may be, and however and whenever such settlement may be
made by the Bank, including interest on the amount of United States of America
currency payable by the Borrower at the rate provided in item (iii) of
Subsection 2.3e from the date of payment of such draft or drawing to the date of
the Borrower's payment to the Bank.

2.3e      Letter of Credit Fee and Related Charges.
          ---------------------------------------- 

          (i) Letter of Credit Fees.  The Borrower agrees to pay, in arrears to
              ---------------------                                            
the Bank, a Letter of Credit Fee per annum equal to one half of one percent
(1/2%) on the Stated Amount (or of any increase or decrease thereof) of each
Letter of Credit, at the end of the first Fiscal Quarter after the issuance of
each Letter of Credit and continuing quarterly thereafter during the term of
each Letter of Credit or any subsequent amendment, renewal or extension thereof
and at the expiration, surrender or final payment thereof.  The foregoing
notwithstanding, if any Event of Default shall have occurred and be continuing
at the time of such issuance of any Letter of Credit or subsequent amendment,
renewal or extension thereof, each Letter of Credit Fee payable thereafter
during the continuation of such Event of Default shall be one hundred (100)
basis points (1%) per annum above the fee otherwise in effect on the scheduled
payment date.

          (ii) Other Fees.  With respect to the amendment or transfer of any
               ----------                                                   
Letter of Credit and each draw made thereunder, the Borrower shall pay
documentary and processing charges in accordance with the Bank's standard
schedule for such charges in effect at the time of such amendment, transfer or
draw, as the case may be.  The first and last of such payments shall be pro
rated to reflect the number of days in the applicable Fiscal Quarter that the
Letter of Credit will be outstanding.  Without limitation the foregoing shall
include all charges and expenses paid or incurred by the Bank in connection with
any Letter of Credit, together with interest thereon at the rate provided in
item (iii) immediately below, including without limitation:  (A) correspondents'
charges, if any, (B) any and all reasonable out-of-pocket expenses and charges
of the Bank in connection with the performance,



                                     -19-

 
administration, interpretation, collection and enforcement of this Agreement and
any Letter of Credit, including all reasonable legal fees and expenses, and (C)
any and all applicable reserve or similar requirements and any and all premiums,
assessments, or levies imposed upon the Bank or any agency or instrumentality of
any government, including without limitation, assessments or charges of any
Governmental Authority; and

          (iii)  Interest.  With respect to draws made under any Letter of
                 --------                                                 
Credit, the Borrower shall pay interest, payable on demand, on the amount paid
by the Bank in respect of each such draw from the Business Day of the draw
through the date such amount is reimbursed by the Borrower (including any such
reimbursement out of the proceeds of Revolving Credit Loans pursuant to
Subsection 2.3d hereof) at a rate which is at all times equal to two percent
(2.00%) per annum in excess of the interest rate applicable under the Base Rate
Option for Revolving Credit Loans.

2.3f      Duty to Review Demands; Obligation Absolute.  The obligation of the
          -------------------------------------------                        
Borrower to reimburse the Bank for draws made under the Letters of Credit shall
be absolute, unconditional and irrevocable and shall be paid directly in
accordance with the terms of this Agreement under all circumstances, including,
without limitation, the following circumstances:

          (i) any lack of validity or enforceability of the Letters of Credit;

          (ii) the existence of any claim, set-off, defense or other right which
the Borrower may have at any time against a beneficiary or any transferee of the
Letters of Credit (or any Persons for whom any such transferee may be acting),
the Bank or any other Person, whether in connection with this Agreement, the
transactions contemplated herein or any unrelated transaction (including any
underlying transaction between the Borrower and the beneficiaries of the Letters
of Credit);

          (iii)  any draft, demand, certificate or any other document presented
under the Letters of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

          (iv) payment by the Bank under a Letter of Credit against presentation
of a demand, draft or certificate or other document which does not comply with
the terms of such Letter of Credit except as the result of gross negligence or
wilful misconduct of the Bank;

          (v) any other circumstance or happening whatsoever, which is similar
to any of the foregoing; and

          (vi) the fact that an Event of Default shall have occurred and be
continuing.

2.3g      Additional Payments.  If by reason of (i) any change in any
          -------------------                                        
Governmental Rule or any change in the interpretation or application by any
judicial or regulatory authority



                                     -20-

 
of any Governmental Rule or (ii) compliance by the Bank with any direction,
request or requirement (whether or not having the force of law) of any
Governmental Authority:

          (i) the Bank shall be subject to any tax, levy, charge or withholding
of any nature or to any variation thereof or to any penalty with respect to the
maintenance or fulfillment of its obligations under this Section 2.3, whether
directly or by such being imposed on or suffered by the Bank;

          (ii) any reserve, deposit or similar requirement is or shall be
applicable, imposed or modified in respect of the Letters of Credit;

          (iii)  there shall be imposed on the Bank any other condition
regarding this Section 2.3 or the Letters of Credit;

and if the result of any of the foregoing is to directly or indirectly increase
the cost to the Bank of issuing, making or maintaining any participation
therein, or to reduce the amount receivable in respect thereof by, the Bank,
then and in any such case the Bank may, at any time after the additional cost is
incurred or the amount receivable is reduced, notify the Borrower, and the
Borrower shall pay on demand such amounts as the Bank may specify to be
necessary to compensate the Bank for such additional cost or reduced receipt,
together with interest on such amount from the date of the notice of such event
which results in such increased cost or reduction in amount receivable until
payment in full thereof at a rate equal at all times to the Base Rate.  The
determination by the Bank, as the case may be, of any amount due pursuant to
this Subsection 2.3g, as set forth in a certificate setting forth the
calculation thereof, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.

2.3h      Indemnification; Nature of an Bank's Duties.  In addition to amounts
          -------------------------------------------                         
payable as elsewhere provided in this Section 2.3, the Borrower hereby agrees to
protect, indemnify, pay and save the Bank harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) which the Bank may incur or be subject to
as a consequence, direct or indirect, of (i) the issuance of the Letters of
Credit or any amendment thereto, other than as a result of the gross negligence
or willful misconduct of the Bank as determined by a court of competent
jurisdiction, (ii) the failure of the Bank to honor a draw under any Letter of
Credit if the Bank in good faith and upon advice of counsel believes that it is
prohibited from making such payment as a result of any act or omission, any
Governmental Authority, or (iii) any material breach by the Borrower of any
representation, warranty, covenant, term or condition in, or the occurrence of
any default under, any document related to the issuance or any amendment of the
Letters of Credit.  If any proceeding shall be brought or threatened against the
Bank by reason of or in connection with any event described in clauses (i)
through (iii) above, the Bank shall promptly notify the Borrower in writing, and
the Borrower shall assume the defense thereof, including the employment of
counsel and payment of all costs of litigation.  Notwithstanding the preceding
sentence, the Bank shall have the right to employ its own counsel and to
determine its own defense of such action in any such case, but the


                                     -21-

 
fees and expenses of such counsel shall be at the expense of the Bank unless (x)
the employment of such counsel shall have been authorized in writing by the
Borrower, (y) the Borrower, after the aforementioned notice of the action, shall
not have employed counsel to have charge of such defense or (z) if the position
of the Borrower is adverse or contrary to the position advocated by the Bank.
In each case described in clauses (x), (y) and (z) immediately above the
reasonable fees and expenses of counsel for the Bank shall be borne by the
Borrower.  The Borrower shall not be liable for any settlement of any such
action affected without its consent.

          The Bank is hereby expressly authorized and directed to honor any
request for payment which is made under and in compliance with the terms of any
Letter of Credit without regard to, and without any duty on the Bank's part to
inquire into, the existence of any disputes or controversies between the
Borrower, the beneficiary of any Letter of Credit or any other Person, or the
respective rights, duties or liabilities of any of them or whether any facts or
occurrences represented in any of the documents presented under any Letter of
Credit are true or correct.  Furthermore, the Borrower fully understands and
agrees that the Bank's sole obligation to the Borrower shall be limited to
honoring requests for payment made under and in compliance with the terms of any
Letter of Credit, the Application therefor and this Agreement and the Bank's
obligation remains so limited even if the Bank may have assisted the Borrower in
the preparation of the wording of any Letter of Credit or any documents required
to be presented thereunder or that the Bank may otherwise be aware of the
underlying transaction giving rise to any Letter of Credit and this Agreement.

          As between the Borrower and the Bank, the Borrower assumes all risks
of the acts and omissions of, or misuse of the Letters of Credit by, the
beneficiaries of the Letters of Credit.  In furtherance and not in limitation of
the foregoing, the Bank shall not be responsible: (i) for the form, validity,
sufficiency, accuracy, genuineness or legal effect of any document submitted by
any party in connection with the application for or the issuance or amendment of
the Letters of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign the Letters of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) for failure of a beneficiary of a
Letter of Credit to comply fully with conditions required in order to draw upon
such Letter of Credit; (iv) for errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telecopy,
telex or otherwise, whether or not they be in cipher; (v) for errors in
interpretation of technical terms; (vi) for any loss or delay in the
transmission or otherwise of any document required in order to make a draw under
the Letters of Credit or of the proceeds thereof; (vii) for the misapplication
by a beneficiary of any Letter of Credit of the proceeds of any drawing under
such Letter of Credit; (viii) for any consequences arising from causes beyond
the control of the Bank, including, without limitation, any Government Rules;
and (ix) for any other circumstances whatsoever in making or failing to make
payment under a Letter of Credit; except that the Borrower shall have a claim
against the Bank, and the Bank shall be liable to the Borrower, to the extent,
but only to the extent, of any direct, as opposed to consequential, damages



                                     -22-

 
suffered by the Borrower, as determined by a court of competent jurisdiction to
be the result of (i) the Bank's willful misconduct or gross negligence in
determining whether documents presented under a Letter of Credit comply with the
terms of the Letter of Credit, (ii) the Bank's willful misconduct or gross
negligence in paying a draw under a Letter of Credit to any Person other than
the beneficiary of such Letter of Credit or its lawful successor, representative
or assign (or as otherwise directed in writing by the beneficiary of such Letter
of Credit) or (iii) the Bank's willful failure to pay under a Letter of Credit
after the presentation to it by the beneficiary of such Letter of Credit or its
lawful successor, representative or assign of a sight draft and certificate or
other documents strictly complying with the terms and conditions of such Letter
of Credit, unless the Bank in good faith and upon advice of counsel believes
that it is prohibited by law or other legal authority from making such payment.
None of the above shall affect, impair, or prevent the vesting of any of the
Bank's rights or powers hereunder.

          Except for the Bank's obligations under a Letter of Credit, the Bank
shall have no liability to the Borrower from a reduction of the Bank's credit
rating or any deterioration in its financial condition.

          The Borrower shall bear and pay all reasonable expenses of every kind
(including all charges for legal services) of the enforcement of any of the
Bank's rights, or of any claim or demand by the Bank against the Borrower, or of
any actual or attempted sale, exchange, enforcement, collection, maintenance,
retention, insurance, compromise, settlement, release, delivery on trust
receipt, or other security agreement, or delivery of any such security, and of
the receipt of proceeds thereof, and will repay to the Bank any such expenses
incurred by the Bank.

          In furtherance and extension and not in limitation of the specific
provisions hereinabove set forth, any action taken or omitted by the Bank under
or in connection with the Letters of Credit or the related sight drafts or
certificates or documents, if taken or omitted in good faith, shall not put the
Bank under any resulting liability to the Borrower.

          Whenever appropriate to prevent unjust enrichment and to the end that
the Borrower shall bear substantially all of the risks relative to any Letter of
Credit and the underlying transactions, the Bank shall be subrogated (for
purposes of defending against the Borrower's claims and proceeding against
others to the extent of the Bank's liability to the Borrower) to the Borrower's
rights against any person, firm or entity who may be liable to the Borrower on
any underlying transaction, to the rights of any holder in due course or person
with similar status against the Borrower, and to the rights of the beneficiary
or its assignee or person with similar status against the Borrower.

2.3i      Construction of Applications and Agreement for Letter of Credit.  This
          ---------------------------------------------------------------       
Agreement is intended to supplement the Applications for Letter of Credit,
executed by the Borrower and delivered to the Bank.  Whenever possible, this
Agreement is to be construed as consistent with said Applications for Letter of
Credit and to the extent that the provisions



                                     -23-

 
of this Agreement and said Applications for Letter of Credit conflict the terms
of this Agreement shall control.

2.3j      Uniform Customs.  Except and to the extent inconsistent with the
          ---------------                                                 
specific provisions hereof, this Agreement, each Letter of Credit hereunder and
all transactions in connection therewith shall be interpreted, construed and
enforced according to:  (i) the "Uniform Customs and Practice for Documentary
Credits" (1993 Revision), International Chamber of Commerce Publication No. 500
and subsequent revisions thereof which shall supersede inconsistent provisions
of applicable law to the extent not prohibited by applicable law and (ii) the
laws of the Commonwealth of Pennsylvania, including, without limitation, the
Uniform Commercial Code, and excluding conflict of laws rules.

2.4       Requests for Revolving Credit Loans, Interest Rate Options and
          --------------------------------------------------------------
Conversions.  Each request for a Revolving Credit Loan and for the election or
- -----------

time) (i) at least one (1) Business Day prior thereto, with respect to Base Rate
Loans and (ii) at least three (3) Business Days prior thereto, with respect to
Euro-Rate Loans.  Any oral request for a Revolving Credit Loan shall be followed
immediately by the Borrower's written confirmation of such request, executed by
an Authorized Officer, which confirmation must set forth the amount and date of
the Revolving Credit Loan, the Interest Rate Option selected and, if applicable,
the Euro-Rate Interest Period being selected and which shall be substantially in
the form of Exhibit "B".  A request from the Borrower pursuant to this Section
            -----------                                                       
2.4 with respect to a Euro-Rate Loan shall irrevocably commit the Borrower to
accept such Euro-Rate Loan on the date specified in such request.

2.5       Method of Disbursements and Payments.  The Bank shall make each
          ------------------------------------                           
Revolving Credit Loan available to the Borrower at the principal office of the
Bank prior to 12:00 noon (Eastern time) on the date such Revolving Credit Loan
is to be made, by the Bank making a deposit into Borrower's demand deposit
account maintained with the Bank.  All payments of principal, interest, Fees,
costs and other amounts due hereunder and under the other Loan Documents shall
be made by the Borrower to the Bank at the Bank's principal office at One PNC
Plaza, 249 Fifth Avenue, Pittsburgh Pennsylvania 15222 not later than 2:00 p.m.
(Eastern time) on the due date.  All such Revolving Credit Loans and payments
shall be made in immediately available funds when either transferred by the Bank
into the Borrower's account with the Bank, or when delivered by the Borrower to
the Bank, as the case may be.

2.6       Loan Account.  The Bank shall open and maintain on its books a Loan
          ------------                                                       
Account in the Borrower's name with respect to Revolving Credit Loans made,
repayments, prepayments, the computation and payment of interest and other
amounts due and sums paid to the Bank hereunder and under the other Loan
Documents.  Except in the case of manifest error in computation, such records
shall be conclusive and binding on the Borrower as to the amount at any time due
to the Bank by the Borrower.


                                     -24-

 
2.7       Payment From Accounts Maintained by Borrower.  For ease of
          --------------------------------------------              
administration, in the event that any payment of principal, interest, Fees,
other expenses or amounts due the Bank under any of the Loan Documents is not
paid when due, the Bank is hereby authorized to effect such payment by debiting
any demand deposit account of the Borrower now or in the future maintained with
the Bank other than accounts maintained in trust for the benefit of third
parties.  This right to debit accounts of the Borrower is in addition to any
right of setoff accorded the Bank hereunder or by operation of law.

2.8       Commitment Fee.  Beginning on March 31, 1997, and continuing on the
          --------------                                                     
last day of each calendar quarter thereafter until the Revolving Credit
Termination Date and on the Revolving Credit Termination Date, the Borrower
shall pay a Commitment Fee to the Bank, in arrears, at the rate of 0.20% (20
basis points) per annum on the average daily unused portion of the Revolving
Credit Commitment during the calendar quarter or period then ended.  The
Commitment Fee shall be computed on the basis of the year of 365 or 366 days, as
the case may be, and paid on the actual number of days elapsed.  The Commitment
Fee shall be calculated from the Closing Date.

2.9       Capital Adequacy.  If (i) any adoption of, change in or interpretation
          ----------------                                                      
of any Governmental Rule, or (ii) compliance with any guideline, request or
directive of any central bank or other Governmental Authority exercising control
over banks or financial institutions generally, including but not limited to
regulations set forth at 12 C.F.R. Part 3 (Appendix A), 12 C.F.R. Part 208
(Appendix A), 12 C.F.R. Part 225 (Appendix A) and 12 C.F.R. Part 325 (Appendix
A), or any court requires that the Revolving Credit Commitment or the Letter of
Credit Commitment hereunder be treated as an asset or otherwise be included for
purposes of calculating the appropriate amount of capital to be maintained by
the Bank or any corporation controlling the Bank (a "Capital Adequacy Event"),
the result of which is to reduce the rate of return on the Bank's capital as a
consequence of the Revolving Credit Commitment or the Letter of Credit
Commitment to a level below that which the Bank could have achieved but for such
Capital Adequacy Event, taking into consideration the Bank's policies with
respect to capital adequacy, by an amount which the Bank deems to be material,
the Bank shall promptly deliver to the Borrower a certificate of the amount
necessary to compensate the Bank for the reduction in the rate of return on its
capital attributable to the Revolving Credit Commitment or the Letter of Credit
Commitment (the "Capital Compensation Amount"), calculated in good faith, using
reasonable attribution and averaging methods, which certificate, absent manifest
error, shall be presumed to be correct.  Such amount shall be due and payable by

Indebtedness owed by



                                     -28-

 
the Borrower from time to time, except other Indebtedness to the extent secured

Environmental Laws.  There are no past, pending or, to the best of the
Borrower's knowledge, threatened Environmental Claims against the Borrower or
its Subsidiaries or any of the property of the Borrower or any of its
Subsidiaries, and, to the best of Borrower's knowledge, there is no condition or
occurrence on any property owned or leased by the Borrower or any of its
Subsidiaries that could reasonably be anticipated (i) to form the basis of a
material Environmental Claim against the Borrower, such Subsidiary or its
properties or (ii) to cause any property owned or leased by the Borrower or any
Subsidiary to be subject to any material restrictions on its ownership,
occupancy or transferability under any Environmental Law.

used, immediately, incidentally or ultimately, to purchase or carry any margin
stock or to extend credit to others for the purpose of purchasing or carrying
margin stock, or for any other purpose which would violate or be inconsistent
with any of the regulations of the Board of Governors of the Federal Reserve
System.

certificate or statement furnished to the Bank by or on behalf of the Borrower
or any Subsidiary pursuant to this Agreement contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the

affected Subsidiary shall have set aside on its books reserves for such claim as
are determined to be adequate by the application of GAAP consistently applied,
but only to the extent that failure to discharge any such liabilities would not
result in any additional liability which would have a Material Adverse Effect;
