$15,000,000.00     April 8, 1997


For value received, and intending to be legally bound, Undersigned, as defined
below, promises to pay to Mellon Bank, N.A. ("Bank") or its order at 8 West
Market Street, Wilkes-Barre, PA 18711 the sum of Fifteen Million Dollars
($15,000,000.00), or such lesser or greater principal amount as may be
outstanding from time to time under a discretionary line of credit established
by Bank for the benefit of Undersigned, with interest on the outstanding balance
from the date of this Promissory Note ("Note") at the rate(s) ("Contractual
Rate[s]") specified herein.

Payment. Principal on the Note shall be due and payable on July 31, 1998.
Accrued interest on the Prime Rate Portion shall be due and payable on the last
Business Day of each calendar month beginning on April 30, 1997. Interest on
each Rate Segment of the As-Offered Rate Portion and the Libor Rate Portion
shall be due and payable on the last day of the corresponding Rate Period. After
maturity of any part of the Note (by acceleration or otherwise), interest on
such part of the Note shall be due and payable ON DEMAND.

Interest Rate Options. The unpaid principal amount of the Note shall bear
interest for each day until due on one or more bases selected by Undersigned
from among the three interest rate options set forth below (each an "Interest
Rate Option" and, collectively, the "Interest Rate Options"). Undersigned
understands and agrees: (a) that Bank may in its sole discretion from time to
time determine that the right of Undersigned to select, convert to or renew a
Prime Rate Option, an As-Offered Rate Option, or a Libor Rate Option is not
available to Bank and (b) that subject to the provisions of this Note
Undersigned may select any number of such Interest Rate Options to apply
simultaneously to different parts of the unpaid principal amount of the Note and
may select any number of Rate Segments to apply simultaneously to different
parts of the As-Offered Rate Option, or Libor Rate Portion.

Available Interest Rate Options.

    Prime Rate Option: A rate per annum (computed on the basis of a year of 365
or 366 days, as the case may be) for each day equal to the Prime Rate, such
interest rate to change automatically from time to time effective as of the
effective date of each change in the Prime Rate.

    Libor Rate Option: For each Rate Segment of the Libor Rate Portion, a rate
per annum (computed on the basis of a year of 360 days and actual days elapsed)
for each day equal to the Libor Rate for such Rate Segment plus four tenths of
one percent (.40%).

    As-Offered Rate Option: For each Rate Segment of the As-Offered Rate
Portion, a rate per annum for such Rate Segment for each day equal to the
As-Offered Rate offered by the Bank in its sole discretion.


Rate Periods. At any time when Undersigned selects, converts to or renews the
As-Offered Rate Option or Libor Rate Option, Undersigned shall fix one or more
periods (the "Rate Periods") during which such Interest Rate Option shall apply,
such periods being set forth below:

As-Offered Rate Option--Periods of 7, 14, 21, 30, 60 or 90 days or other period
as agreed to between the Undersigned and the Bank ("As-Offered Rate Period")

Libor Rate Option--1, 2 or 3 months or other period as agreed to between the
Undersigned and the Bank ("Libor Rate Period")

Bank's right to payment of principal and interest under the Note shall in no way
be affected by the fact that one or more Rate Periods may be in effect.

Amounts. Every selection of, conversion to or renewal of any Interest Rate
Option shall be in a principal amount of at least $100,000.00 selected by
Undersigned and acceptable to Bank.

Interest After Maturity. After the principal amount of any part of the Prime
Rate Portion shall have become due and payable, whether by acceleration or
otherwise, such amount shall bear interest for each day until paid (before and
after judgment) at a rate per annum (based on a year of 365 or 366 days, as the
case may be) which for each day shall be the greater of (a) 2% above the Prime
Rate Option on the day such amount became due and (b) 2% above the Prime Rate
Option, such interest rate to change automatically from time to time effective
as of the effective date of each change in the Prime Rate. After the principal
amount of any part of the As-Offered Rate Portion or the Libor Rate Portion
shall have become due and payable, whether by acceleration or otherwise, such
amount shall bear interest for each day until paid (before and after judgment)
(c) until the end of the applicable then-current Rate Period as a rate per annum
2% above such Interest Rate Option otherwise applicable to such part and (d)
thereafter in accordance with the previous sentence.

Selection, Conversion or Renewal of Rate Options. Subject to the other
provisions of this Supplement, Undersigned may select any Interest Rate Option
to apply to any borrowing evidenced by the Note. Subject to the other provisions
of this Supplement, Undersigned may convert any part of the unpaid principal
amount of the Note from any Interest Rate Option to



any other Interest Rate Option: (a) at any time with respect to conversion from
the Prime Rate Option to any other Interest Rate Option, and (b) at the
expiration of any Rate Period with respect to conversion from or renewals of the
As-Offered Rate Option or the Libor Rate Option as to the Rate Segment
corresponding to such expiring Rate Period. Whenever Undersigned desires to
select, convert or renew any Interest Rate Option, Undersigned shall give Bank
Standard Notice thereof (which shall be irrevocable), specifying the date,
amount and type of the proposed new Rate Option. If such notice has been duly
given, and if Bank in its sole discretion approves the proposed selection,
conversion or renewal, on and after the date specified in such notice interest
shall be calculated upon the unpaid principal  amount of the Note taking into
account such selection, conversion or renewal.


Prime Rate Fallback. If any Rate Period expires, any part of the Rate Segment
corresponding to such Rate Period which has not been converted or renewed in
accordance with Section 6 hereof automatically shall be converted to the Prime
Rate Option. If Undersigned fails to select, or if Bank fails to approve, an
Interest Rate Option to apply to any borrowing evidenced by the Note, such
borrowing shall be deemed to be at the Prime Rate Option. If any time the Bank
shall have determined in good faith (which determination shall be conclusive)
that the accrual of interest at the As-Offered Rate Option or the Libor Rate
Option has been made unascertainable, impractical or unlawful by compliance with
the Bank in good faith with any law (including common law), constitution,
statute, treaty, regulation, rule, ordinance, order, injunction, writ, decree or
award of any government or political subdivision or any agency, authority,
bureau, central bank, commission, department or instrumentality of either, or
any court, tribunal, grand jury or arbitrator, in each case whether foreign or
domestic, or adminsitration thereof by any official body charged with the
interpretation or administration thereof or with any request or directive of any
such official body (whether or not having the force of law), then, and in any
such event, the outstanding principal amount of this Note subject to such
Interest Rate Options shall accrue interest at the Prime Rate Option and the
Undersigned shall not have the right to select such Interest Rate Option.

Prepayments. Undersigned shall have the right at its option from time to time to
prepay the Prime Rate Portion in whole or in part. Undersigned shall have no
right to prepay any part of the As-Offered Rate Portion or the Libor Rate
Portion at any time without the prior written consent of Bank except that
Undersigned may prepay any part of any Rate Segment at the expiration of the
Rate Period corresponding to such Rate Segment. Prepayments shall be made by
giving the Bank Standard Notice thereof (which shall be irrevocable), specifying
the date, and amount and type of prepayment, and upon such date the amount so
specified and accrued interest thereon shall be due and payable.

Indemnity.  Undersigned shall indemnify Bank against any loss or expense
(including loss of margin) which Bank has sustained or incurred as a consequence
of:

     (i)  payment, prepayment or conversion of any part of any Rate Segment of
the As-Offered Rate Portion or the Libor Rate Portion on a day other than the
last day of the corresponding Rate Period (whether or not any such payment is
pursuant to demand by Bank under the Note and whether or not any such payment,
prepayment or conversion is consented to by Bank, unless Bank shall have
expressly waived such indemnity in writing);

     (ii)  attempt by Undersigned to revoke in whole or part any irrevocable
notice given pursuant to Section 6 of this Supplement; or

     (iii)  breach of or default by any Obligor in the performance or observance
of any covenant or condition contained in the Loan Agreement, the Note or any
separate security, guarantee or suretyship agreement between Bank and any
Obligor.

     If Bank sustains any such loss or expense it shall from time to time notify
Undersigned of the amount determined in good faith by Bank (which determination
shall be conclusive) to be necessary to indemnify Bank for such loss or expense.
Such amount shall be due and payable by Undersigned on demand.


Records.  The unpaid principal amount of the Note, the unpaid interest accrued
thereon, the interest rate or rates applicable to such unpaid principal amount,
the duration of such applicability and the date and amount of each payment or
demand shall at all times be ascertained from the books and records created
by Bank, which shall be conclusive absent manifest error.

Notices.  All notices under this Note shall be in writing or by telephone
promptly confirmed in writing, and all such writings shall be sent by
first-class, first-class express or certified mail, telecopier or by hand
delivery, in all cases with charges prepaid. All notices shall be sent to the
applicable party at the address stated on the signature page hereof or in
accordance with the last unrevoked written direction from such party to the
other parties hereto. All notices by Undersigned shall be effective when
received by Bank and all notices by Bank shall be effective when telephoned,
deposited in the mail or hand delivered. Written notices or confirmations by
Undersigned shall not be deemed records of Bank whether or not received by Bank.

purporting to be from or authorized by Undersigned.

procedures (which determination shall be conclusive) to be the average of the
rates per annum for deposits in United States dollars offered to major money
center banks in the London interbank market at approximately 11:00 a.m., London

Segment (or, if there are no such comparable amounts actively traded, the
smallest amounts actively traded) and having maturities comparable to such Rate
Period by (B) a number equal to 1.00 minus the Libor Rate Reserve Percentage for
such day. The "Libor Rate" may also be expressed by the following formula:

(j) "Libor Rate Reserve Percentage" for any day shall mean the percentage

Percentage. (k) "London Business Day" shall mean a day for dealing in deposits
in United States dollars by and among banks in the London interbank market. (l)

whole, of the unpaid principal amount of the Note bearing interest at such time
under the Prime Rate Option or in accordance with the first sentence of Section

time equals the principal amount of such Portion at such time). (o) "Standard

    (ii)   at least three London Business Days in advance in the case of
selection of, conversion to or renewal of the Libor Rate Option or prepayment of
any Libor Rate Portion.

Standard Notice must be provided no later than 1:00 o'clock p.m., Wilkes-Barre
time, on the last day permitted for such notice.


7.   Confession of Judgment. Undersigned hereby empowers the prothonotary or any
attorney of any court of record to appear for Undersigned and to confess
judgment as often as necessary against Undersigned in favor of the holder
hereof, as of any term, for the above sum plus interest due under the terms
hereof, together with costs of legal proceedings and an attorney's commission

personal property from execution.
