   2.1.   THE REVOLVING LOANS.

     (a)  REVOLVING LOANS; REVOLVING LOAN COMMITMENT.  Subject to the terms
and conditions herein set forth and in reliance upon the representations,
warranties and covenants contained herein, each Bank agrees, severally and
not jointly, to make revolving credit loans (collectively, the "REVOLVING
LOANS" and individually a "REVOLVING LOAN") to the Borrowers during the
period beginning on the date hereof and ending on September 30, 2000 or on
the earlier date of termination in full, pursuant to Section 2.6, Section 2.7
or Section 8.1 hereof, of the obligations of such Bank under this Section 2.1
(September 30, 2000 or such earlier date of termination being herein called
the "REVOLVING LOAN TERMINATION DATE") in amounts not to exceed at any time
outstanding, in the aggregate, the commitment amount set forth opposite the
name of such Bank on Exhibit A hereto (each such amount, as the same may be
reduced pursuant to Section 2.6 hereof being hereinafter called such Bank's
"REVOLVING LOAN COMMITMENT").  The Banks' collective commitment to make
Revolving Loans under this Credit Facility shall be the "AGGREGATE REVOLVING
LOAN COMMITMENT," and shall include a $3,000,000 sublimit for Standby Letters
of Credit.  All Revolving Loans shall be made by the Banks simultaneously and
PRO RATA in accordance with their respective Revolving Loan Commitments. All
Revolving Loans shall be


                                      21
<PAGE>

made to the Borrowers at the primary office of the Administrative Agent in
Philadelphia located at Broad and Chestnut Streets, Philadelphia,
Pennsylvania 19101.  The Revolving Loan Commitment may be renewed annually at
the Borrowers' request and the sole discretion of the Banks.

     (b)  INTEREST RATE OPTIONS.  Revolving Loans shall bear interest at (i)
the Base Rate plus the Applicable Margin for Revolving Loans, or (ii)
Adjusted LIBO Rate plus the Applicable Margin for Revolving Loans, provided
that, in the case of LIBO Rate Loans, (a) not more than five such Loans may
be outstanding at any one time, and (b) no LIBO Rate Loan may have an
Interest Period extending beyond the Revolving Loan Termination Date unless
it is converted to a Term Loan pursuant to the provisions of this Agreement.

     (c)  MAXIMUM LOANS OUTSTANDING.  The Borrowers shall not be entitled to
any new Revolving Loan if, after giving effect to such Loan, the unpaid
amount of the then outstanding Loans would exceed the lesser of (i) the
Aggregate Revolving Loan Commitment or (ii) the then current Borrowing Base,
as stated in the most recent Borrowing Base Certificate furnished to the
Banks as provided herein.  For purposes of determining the amount of
Revolving Loans outstanding, the Standby Letters of Credit issued pursuant to
Section 2.3 hereof shall be deemed Revolving Loans and shall be added to the
Revolving Loans outstanding to determine the aggregate Revolving Loans
outstanding.

     (d)  MINIMUM LOAN AMOUNT.  Except for Loans which exhaust the full
remaining amount of the Aggregate Revolving Loan Commitment and conversions
which result in the conversion of all Loans subject to a particular interest
rate option, each of which may be in lesser amounts, (i) each LIBO Rate Loan
when made (and each conversion of Base Rate Loans into LIBO Rate Loans) shall
be in an amount at least equal to $3,000,000 or, if greater, then in such
minimum amount plus $100,000 multiples, and (ii) each Base Rate Loan when
made (and each conversion of LIBO Rate Loans into Base Rate Loans) shall be
in an amount at least equal to $150,000.

     (e)  PREPAYMENT AND REBORROWING.  Prior to the Revolving Loan
Termination Date and within the limits of the Aggregate Revolving Loan
Commitment and the Borrowing Base, the Borrowers may borrow, prepay and
reborrow Revolving Loans.  All Revolving Loans shall mature and be due and
payable on the Revolving Loan Termination Date unless they are converted to
Term Loans pursuant to Section 2.8.

     (f)  REVOLVING LOAN COMMITMENT PERCENTAGES.  The obligation of each Bank
to make a Revolving Loan to any Borrower at any time shall be limited to its
percentage (the "REVOLVING LOAN COMMITMENT PERCENTAGE") as set forth opposite
its name on Exhibit A hereto multiplied by the aggregate principal amount of
the Revolving Loan requested.  The principal amounts of the respective
Revolving Loans made by the Banks on the occasion of each Borrowing shall be
pro rata in accordance with their respective Revolving Loan Commitment
Percentages. No Bank shall be required or permitted to make any Loan if,
immediately after giving effect to such Loan, and the application of the
proceeds of a Loan to the extent applied to


                                      22
<PAGE>

the repayment of the Loans, the sum of such Bank's Loans outstanding would
exceed such Bank's Revolving Loan Commitment.

     (g)  SEVERAL OBLIGATIONS.  The failure of any one or more Banks to make
Revolving Loans in accordance with its or their obligations shall not relieve
the other Banks of their several obligations hereunder, but in no event shall
the aggregate amount at any one time outstanding which any Bank shall be
required to lend hereunder exceed its Revolving Loan Commitment.

   2.2.   THE REVOLVING NOTES.  The Revolving Loans made by each Bank shall
be evidenced by a single promissory note of the Borrowers under which they
shall be jointly and severally liable (each such promissory note as it may be
amended, extended, modified or renewed a "REVOLVING CREDIT NOTE" and together
the "REVOLVING CREDIT NOTES") in principal face amount equal to such Bank's
Revolving Loan Commitment, payable to the order of such Bank and otherwise in
the form attached hereto as Exhibit C.  The Revolving Credit Notes shall be
dated the date of issuance, shall bear interest at the rate per annum and be
payable as to principal and interest in accordance with the terms hereof.
Each outstanding Revolving Loan shall be due and payable as set forth in
Section hereof unless the maturity of said Loans is accelerated as provided
in Section 2.6 or Section 8.1 hereof or converted as provided in Sections 2.8
or 2.7 hereof.  Notwithstanding the stated amount of any Revolving Credit
Note, the liability of the Borrowers under each Revolving Credit Note shall
be limited at all times to the outstanding principal amount of the Revolving
Loans by each Bank evidenced thereby, plus all interest accrued thereon and
the amount of all costs and expenses then payable hereunder, as established
by each such Bank's books and records, which books and records shall be
conclusive absent manifest error.

   2.3.   STANDBY LETTERS OF CREDIT.  The Administrative Agent, under the
terms and subject to the conditions of this Agreement, on behalf of itself
and each other Bank in the same proportions as each Bank's Revolving Loan
Commitment bears to the Aggregate Revolving Loan Commitment, shall provide
Standby Letters of Credit to the Borrowers, from time to time prior to the
Revolving Loan Termination Date, as requested by the Borrowers, provided that
(i) the aggregate amount of Standby Letters of Credit outstanding at any one
time shall not exceed $3,000,000 or such lesser amount, if any, as will, when
added to the amount of the Revolving Loans then outstanding, aggregate more
than the Aggregate Revolving Loan Commitment (or such lesser amount as the
Borrowers are entitled to borrow hereunder at such time by reason of the
limitation of the Borrowing Base or otherwise); (ii) no Standby Letter of
Credit shall be for a term longer than one year; and (iii) no Standby Letters
of Credit shall be required to be issued when any Event of Default or
Potential Default exists.

     The Borrowers shall request a Standby Letter of Credit by delivering a
completed letter of credit application to the Administrative Agent on such
form as may be specified by the Administrative Agent not less than three
Business Days prior to the date specified by the Borrowers as the date the
Standby Letter of Credit is to be issued.  The standard form of the
Administrative Agent's letter of credit application as currently in effect
shall be used.  The Administrative Agent shall notify the Banks promptly
after the issuance of any Standby Letter of Credit and will provide the Banks
copies of the periodic Borrowing Base Certificates showing


                                      23
<PAGE>

the current balance of outstanding Standby Letters of Credit, as delivered by
the Borrowers to the Administrative Agent.

     Standby Letters of Credit fees will be equal to the Applicable Margin
for LIBO Rate Loans on an annual basis, calculated on the basis of the days
actually elapsed in a year of 360 days (paid to the Administrative Agent for
distribution to the Banks) plus a Fronting Fee of 0.125% per year to be paid
to the Fronting Bank for its own account.  Such Fees will be calculated based
on the aggregate stated amount for each Letter of Credit, and will be due
quarterly in arrears, commencing on the last Business Day of the calendar
quarter in which the Standby Letter of Credit is issued.

     If any obligation of the Borrowers to pay money in connection with any
Standby Letter of Credit is not met when requested by the Administrative
Agent as permitted by the applicable letter of credit application and the
reimbursement agreement contained therein, the amount due shall be funded
automatically by a Revolving Loan which Loan shall be made without regard to
any minimum borrowing requirement, condition precedent herein, or Event of
Default hereunder which would otherwise entitle any Bank or the Banks not to
provide such Revolving Loan, and each Bank shall make its proportionate share
of such Revolving Loan.  Any obligation of the Borrowers to pay money in
connection with any Standby Letter of Credit or the application therefor
shall be deemed secured as if made as a Loan hereunder.  In the event the
Borrowers shall terminate the Aggregate Revolving Loan Commitment as provided
in Section  and shall pay the outstanding principal amount of the Revolving
Loans in full and with interest or the Revolving Loan Termination Date shall
occur at a time when one or more Standby Letters of Credit remain
outstanding, then the Borrowers shall furnish to the Administrative Agent
within two Business Days such amount of cash, to be held as cash collateral
and invested in certificates of deposit of the Administrative Agent with
interest payable to the Borrowers, as will pay the maximum amount which may
be drawn by beneficiaries of Standby Letters of Credit outstanding at the
date of such termination or the Revolving Loan Termination Date, as
applicable.

   2.4.   FUNDING PROCEDURES.

     (a)  REQUEST FOR ADVANCE.  Each request for a Revolving Loan or the
conversion or renewal of an interest rate with respect to a Loan shall be
made not later than 2:00 p.m. eastern prevailing time on a Business Day by

Borrowers or, in the alternative, a telephone request followed promptly by

shall be that form provided to the Borrowers by the Administrative Agent.
Each request shall be received not less than one Business Day prior to the
date of the proposed borrowing, conversion or renewal in the case of Base
Rate Loans, and three London Business Days prior to the date of the proposed
borrowing, conversion or renewal in the case of LIBO Rate Loans.  No request
shall be effective until actually received in writing by the Administrative
Agent.  The Borrowers


                                      24
<PAGE>

may not request more than three advances per week.  Each request for advance
shall be for Loans at a single interest rate option.

     (b)  ACTIONS BY THE ADMINISTRATIVE AGENT.  Upon receipt of a Request for
Advance and if the conditions precedent provided herein shall be satisfied at
the time of such request, the Administrative Agent promptly shall notify each
Bank of such request and of such Bank's ratable share of such Loan.  Upon
receipt by the Administrative Agent of a Request for Advance, the request
shall not be revocable by the Borrowers.

     (c)  AVAILABILITY OF FUNDS. Not later than 1:00 p.m. eastern prevailing
time on the date of each Loan, each Bank shall make available (except as
provided in clause (d) below) its ratable share of such Loan, in immediately
available funds, to the Administrative Agent at the address set forth
opposite its name on the signature page hereof or at such account in London
as the Administrative Agent shall specify to the Borrowers and the Banks.
Unless the Administrative Agent knows that any applicable condition specified
herein has not been satisfied, it will make the funds so received from the
Banks immediately available to the Borrowers on the date of each Loan by a
credit to the account of the Borrowers at the Administrative Agent's
aforesaid address.

     (d)  FUNDING ASSUMPTIONS.  Unless the Administrative Agent shall have
been notified by any Bank at least one Business Day prior to the date of the
making, conversion or renewal of any LIBO Rate Loan, or by 3:00 p.m. eastern
prevailing time on the date a Base Rate Loan is requested, that such Bank
does not intend to make available to the Administrative Agent, such Bank's
portion of the total amount of the Loan to be made, converted or renewed on
such date, the Administrative Agent may assume that such Bank has made such
amount available to the Administrative Agent on the date of the Loan and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrowers a corresponding amount.  If and to the extent such Bank shall
not have so made such funds available to the Administrative Agent, such Bank
agrees to repay the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the
date such amount is made available to the Borrowers until the date such
amount is repaid to the Administrative Agent, at the Federal Funds Rate plus
50 basis points for three Business Days, and thereafter at the Base Rate.  If
such Bank shall repay to the Administrative Agent such corresponding amount,
such amounts so repaid shall constitute such Bank's Loan for purposes of this
Agreement.  If such Bank does not repay such corresponding amount forthwith
upon the Administrative Agent's demand therefor, the Administrative Agent
shall promptly notify the Borrowers, and the Borrowers shall immediately pay
such corresponding amount to the Administrative Agent, without any prepayment
penalty or premium, but with interest on the amount repaid, for each day from
the date such amount is made available to the Borrowers until the date such
amount is repaid to the Administrative Agent, at the rate of interest
applicable at the time to such Loan.  Nothing herein shall be deemed to
relieve any Bank of its obligation to fulfill its Revolving Loan Commitment
hereunder or to prejudice any rights which the Borrowers may have against any
Bank as a result of any default by such Bank hereunder.


                                      25
<PAGE>

     (e)  PROCEEDS OF LOAN BEING REPAID.  If the Banks make a Loan on a day
on which all or any part of an outstanding Loan from the Banks is to be
repaid, each Bank shall apply the proceeds of its new Loan to make such
repayment and only an amount equal to the difference (if any) between the
amount being borrowed and the amount being repaid shall be made available by
such Bank to the Administrative Agent as provided in clause (c).

   2.5.   REVOLVING LOAN COMMITMENT FEE.  The Borrowers agree to pay to the
Administrative Agent for the account of each Bank as compensation for the
Aggregate Revolving Loan Commitment, a fee based on the average daily unused
committed amount of the Revolving Credit Facility (the "REVOLVING LOAN
COMMITMENT FEE") computed as indicated on the chart set forth on Exhibit D
hereto, based on the then applicable Leverage Ratio of the Borrowers. The
Revolving Loan Commitment Fee shall be payable quarterly in arrears on the
first day of each January, April, July and October, commencing October 1,
1998 (for the three month period or portion thereof ended on the preceding
day), and on the Revolving Loan Termination Date.  The Revolving Loan
Commitment Fee shall be calculated on the basis of the actual number of days
elapsed in a 360-day year.

   2.6.   REDUCTION OR TERMINATION OF REVOLVING LOAN COMMITMENTS.

          (a)  VOLUNTARY.  The Borrowers may at any time, on not less than
one Business Days' written notice, terminate or permanently reduce the
Aggregate Revolving Loan Commitment pro rata among the Banks, provided that
any reduction shall be in the minimum amount of $1,000,000 or a multiple
thereof and that no such reduction shall cause the principal amount of Loans
and Standby Letters of Credit outstanding to exceed the reduced Aggregate
Revolving Loan Commitment or the Borrowing Base, whichever is less.

          (b)  REVOLVING LOAN COMMITMENT TERMINATION.  In the event the
Aggregate Revolving Loan Commitment is terminated, the Revolving Loan
Termination Date shall be accelerated to the date of such termination and
Borrowers shall, simultaneously with such termination, repay the Revolving
Loans in accordance with Section 2.12.

   2.7.   MANDATORY PREPAYMENTS; CONVERSION TO TERM LOANS.  If the aggregate
principal amount of advances and the face amount of Standby Letters of Credit
outstanding under this Credit Facility at any time exceeds the total
Borrowing Base, the Borrowers shall make immediate prepayments to reduce such
outstanding advances under the Loans, plus the face amount of such Standby
Letters of Credit to an amount not to exceed the Borrowing Base; provided,
however, that if (i) this mandatory prepayment is required by a reduction to
the Borrowing Base necessitated by the results of an appraisal of the
Equipment, and (ii) the amount of the required mandatory prepayment would not
exceed 15% of all advances then outstanding under the Credit Facility, the
Borrowers may elect to convert all outstanding advances under the Credit
Facility to Term Loans pursuant to Section 2.8(b).  Such conversion will
immediately cause the Revolving Loan Termination Date to accelerate and the
Banks will have no further obligation to make any Revolving Credit Loans
under this Agreement.

   2.8.   TERM LOANS.


                                      26
<PAGE>

     (a)  CONVERSION ON REVOLVING LOAN TERMINATION DATE.  On the Revolving
Loan Termination Date, all or a portion of the Revolving Loans then
outstanding may at Borrowers' option be converted to term loans in accordance
with the provisions of this Section 2.8 (individually, a "TERM LOAN" and
collectively, the "TERM LOANS").  All Term Loans so created shall mature on
the applicable Term Loan Maturity Date. Any and all amounts not so converted
shall be due and payable on the Revolving Loan Termination Date.

     (b)  CONVERSION PRIOR TO REVOLVING LOAN TERMINATION DATE; TERMINATION OF
REVOLVING CREDIT FACILITY.  If the Borrowers have the option of converting
their Revolving Loans to Term Loans pursuant to Section 2.7, such conversion
will immediately terminate the Revolving Credit Facility.

     (c)  INTEREST RATE OPTIONS.  Term Loans shall bear interest at (i) the
Base Rate plus the Applicable Margin for Term Loans, or (ii) the Adjusted
LIBO Rate plus the Applicable Margin for Term Loans, provided that in the
case of LIBO Rate Term Loans, (a) not more than five such Loans may be
outstanding at any one time, (b) any Term Loan may, at the Borrowers' option,
continue the Interest Period assigned to the Revolving Loan from which it was
converted, if such Interest Period would expire after the Conversion Date,
and (c) no LIBO Rate Term Loan may have an Interest Period extending beyond
the Term Loan Maturity Date.

     (d)  THE TERM NOTES.  Each Term Loan created at the Revolving Facility
Termination Date or any Conversion Date shall be evidenced by a separate
promissory note of the Borrowers, under which they shall be jointly and
severally liable, substantially in the form of Exhibit I hereto (each such
promissory note as it may be amended, extended, modified or renewed a "TERM
NOTE" and together the "TERM NOTES.")

     (e)  AMORTIZATION OF TERM LOANS.  Each Term Loan shall require quarterly
principal payments every three months (commencing three months from the
Conversion Date) based upon the amortization schedules set forth in
Subsections 2.8(e)(i) and (ii) below, with the final payment of all amounts
outstanding, plus accrued interest, coming due four years from such Term
Loan's Conversion Date (such date with respect to a Term Loan being the "TERM
LOAN MATURITY DATE").

           (i) To the extent the aggregate outstanding balance of the
Revolving Loans on the Conversion Date is equal to or less than the Engine
and Aircraft Advance Amount calculated as of the Conversion Date, such
principal balance, when converted into Term Loans, shall be amortized as
follows:  During the period from the Conversion Date to the day before the
first anniversary of the Conversion Date, 14.4% of the aggregate principal
balance existing on the Conversion Date shall be repaid in four equal
quarterly installments; during the period from the first anniversary of the
Conversion Date to the day before the second anniversary of the Conversion
Date, 15.6% of the aggregate principal balance existing on the Conversion
Date shall be repaid in four equal quarterly installments; during the period
from the second anniversary of the Conversion Date to the day before the
third anniversary of the Conversion Date, 16.8% of the aggregate principal
balance existing on the Conversion Date shall be repaid in four equal
quarterly installments; during the period from the third anniversary of the
Conversion Date to the


                                      28
<PAGE>

day before the fourth anniversary of the Conversion Date, 18.0% of the
aggregate principal balance existing on the Conversion Date shall be repaid
in four equal quarterly installments; and on the fourth anniversary of the
Conversion Date, the entire remaining principal balance (35.2% of the
aggregate principal balance existing on the Conversion Date) shall be repaid
in full.

           (ii)     To the extent that the aggregate outstanding balance of
the Revolving Loans on the Conversion Date exceeds the Engine and Aircraft
Advance Amount calculated as of the Conversion Date, such excess principal
balance, when converted into Term Loans, shall be amortized as follows:
during each successive one-year period following the Conversion Date, 25.0%
of the aggregate excess principal balance existing on the Conversion Date
shall be repaid in four equal quarterly installments.

   2.9.   PAYMENT OF ADDITIONAL AMOUNT.  If any principal of a LIBO Rate Loan
shall be repaid (whether upon mandatory or voluntary prepayment, reduction of
the Aggregate Revolving Loan Commitment after acceleration or for any other
reason) or converted to a Base Rate Loan prior to the last day of the
Interest Period applicable to such LIBO Rate Loan or if the Borrowers fail
for any reason to borrow a LIBO Rate Loan after giving irrevocable notice
pursuant to Section 2.4, they shall pay to each Bank, in addition to the
principal and interest then to be paid, such additional amounts as may be
necessary to compensate each Bank for all direct and indirect costs and
losses (including losses resulting from redeployment of prepaid or unborrowed
funds at rates lower than the cost of such funds to such Bank, and including
lost profits incurred or sustained by such Bank) as a result of such
repayment or failure to borrow (the "ADDITIONAL AMOUNT").  The Additional
Amount (which each Bank shall take reasonable measures to minimize) shall be
specified in a written notice or certificate delivered to the Borrowers by
the Administrative Agent in the form provided by each Bank sustaining such
costs or losses.  Such notice or certificate shall contain a calculation in
reasonable detail of the Additional Amount to be compensated and shall be
conclusive as to the facts and the amounts stated therein, absent manifest
error.

   2.10.  INTEREST.

     (a)  BASE RATE LOANS.  Each Base Rate Loan shall bear interest on the
unpaid principal balance thereof from day to day at a rate per annum which at
all times shall be equal to the Base Rate plus the Applicable Margin.
Interest on Base Rate Loans shall be computed on the basis of a year of 365
or 366 days, as applicable, for the actual days elapsed, if the Base Rate is
equal to the prime rate of the Administrative Agent.  Interest on Base Rate
Loans shall be computed on the basis of a year of 360 days, for the actual
days elapsed, if the Base Rate is equal to the Federal Funds Rate plus 1/2 of
1% per annum.

     (b)  LIBO RATE LOANS.  Each LIBO Rate Loan shall bear interest from its
effective date on the unpaid principal amount thereof at Adjusted LIBO Rate
plus the Applicable Margin.  Interest on LIBO Rate Loans shall be computed on
the basis of a year of 360 days, for the actual days elapsed, and shall be
payable on the last day of the applicable Interest Period, or quarterly,
whichever is earlier.  If a LIBO Rate Loan is for a period of three months or
more, it shall be payable quarterly.


                                      28
<PAGE>

     (c)  CONVERSION TO BASE RATE.  Unless the Borrowers shall have elected
in accordance with the provisions of Section 2.4 or this Section 2.10 that
LIBO Rate apply to the one, two, three or six-month period immediately
succeeding a particular Interest Period, upon the termination of such
Interest Period the applicable Loan shall bear interest at the Base Rate plus
the Applicable Margin until such time as the Borrowers elect to request a new
LIBO Rate Loan for a subsequent Interest Period.

     (d)  RENEWALS AND CONVERSIONS.  The Borrowers shall have the right to
convert Base Rate Loans into LIBO Rate Loans, and vice versa, and to renew
LIBO Rate Loans from time to time, provided that:  (i) the Borrowers shall
give the Administrative Agent notice of each permitted conversion or renewal;
(ii) LIBO Rate Loans may be converted or renewed only as of the last day of
the applicable Interest Period for such Loans; (iii) without the consent of
the Majority Banks, no Base Rate Loan may be converted into a LIBO Rate Loan,
and no Interest Period may be renewed if on the proposed date of conversion
an Event of Default, or Potential Default exists or would thereby occur.  The
Administrative Agent shall use its best efforts to notify the Borrowers and
the Banks of the effectiveness of such conversion or renewal, and the new
interest rate to which the converted or renewed Loan is subject, as soon as
practicable after the conversion; provided, however, that any failure to give
such notice shall not affect the Borrowers' obligations or the Banks' rights
and remedies hereunder in any way whatsoever.

     (e)  INTERIM PAYMENTS AT BASE RATE.  If at any time the Borrowers
request that Adjusted LIBO Rate plus the Applicable Margin be applicable to a
Loan for a particular Interest Period and a payment of principal is due
within such period (other than on the last day of such Interest Period), only
that portion of that Loan equal to the outstanding principal amount of the
Loan less the principal installment due during such period shall bear
interest at Adjusted LIBO Rate plus the Applicable Margin for such Interest
Period.  The portion of that Loan equal to the principal installment due
during such period shall bear interest at the Base Rate plus the Applicable
Margin.

     (f)  REINSTATEMENTS.  The liability of the Borrowers under this Section
2.10 shall continue to be effective or be automatically reinstated, as the
case may be, if at any time payment, in whole or in part, of any of the
payments to the Banks is rescinded or must otherwise be restored or returned
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization
of the Borrowers or any other Person, or upon or as a result of the
appointment of a custodian, receiver, trustee or other officer with similar
powers with respect to the Borrowers or any other Person or any substantial
part of its property, or otherwise, all as though such payment had not been
made.

   2.11.  VOLUNTARY PREPAYMENTS.

     (a)  BASE RATE LOANS.  On one Business Day's notice to the
Administrative Agent, the Borrowers may, without penalty, at their option,
prepay any Base Rate Loan in whole at any time or in part from time to time,
provided that each partial prepayment shall be in the minimum principal
amount of $150,000 or, if greater, then in multiples thereof and, if less
than $150,000 shall be outstanding, in principal amount equal to amount
remaining outstanding. Notwithstanding the foregoing, prepayments may be made
in connection with the release of


                                      29
<PAGE>

collateral as provided in Section 9.3, which prepayments shall not be subject
to the requirements of the previous sentence.

     (b)  LIBO RATE LOANS.  On three London Business Days' notice to the
Administrative Agent, the Borrowers may, without penalty, at their option,
prepay any LIBO Rate Loan in whole at any time or in part from time to time,
provided that each partial prepayment shall be in the minimum principal
amount of $1,000,000 or, if greater, then in multiples of $100,000 and, if
less than $1,000,000 shall be outstanding, in principal amount equal to the
amount remaining outstanding provided that if they shall prepay a LIBO Rate
Loan prior to the last day of the applicable Interest Period, or shall fail
to borrow any LIBO Rate Loan on the date such Loan is to be made, they shall
pay to each Bank, in addition to the principal and interest then to be paid
in the case of a prepayment, on such date of prepayment, the Additional
Amount incurred or sustained by such Bank as a result of such prepayment or
failure to borrow as provided in Section 2.9.

   2.12.  PAYMENTS.

     (a)  ACCRUED INTEREST.  Accrued interest on all Base Rate Loans shall be
due and payable in arrears on the first Business Day of each calendar month.
Interest on LIBO Rate Loans shall be payable in arrears on the last day of
the applicable Interest Period or quarterly, whichever is earlier. Each
Revolving Loan shall mature as provided in Section 2.1.

     (b)  FORM OF PAYMENTS, APPLICATION OF PAYMENTS, PAYMENT ADMINISTRATION,
ETC.  Subject to the provisions of Section Section 11.7(b) hereto, all
payments of principal, interest, fees, or other amounts payable by the
Borrowers hereunder shall be applied to the Loans in such order and to such
extent as shall be specified by the Borrowers by written notice to the
Administrative Agent at the time of such payment or prepayment.  Such
payments shall be remitted in United States dollars to the Administrative
Agent on behalf of the Banks at the address set forth opposite its name on
the signature page hereof or at such office or account as the Administrative
Agent shall specify to the Borrowers, in immediately available funds not
later than 2:00 p.m. eastern prevailing time on the day when due.  Whenever
any payment is stated as due on a day which is not a Business Day, the
maturity of such payment shall, except as otherwise provided in the
definition of "Interest Period," be extended to the next succeeding Business
Day and interest and commitment fees shall continue to accrue during such
extension.  The Borrowers authorize the Administrative Agent to deduct from
any account of the Borrowers maintained at the Administrative Agent or over
which the Administrative Agent has control any amount payable under this
Agreement, the Notes or any other Loan Document which is not paid in a timely
manner.  The Administrative Agent's failure to deliver any bill, statement or
invoice with respect to amounts due under this Section or under any Loan
Document shall not affect the Borrowers' joint and several obligation to pay
any installment of principal, interest or any other amount under this
Agreement when due and payable.

     (c)  DEMAND DEPOSIT ACCOUNT.  The Borrowers shall maintain at least one
demand deposit account with the Administrative Agent for purposes of this
Agreement.  The Borrowers authorize the Administrative Agent to deposit into
said account all amounts to be advanced to the


                                      30
<PAGE>

Borrowers hereunder.  Further, the Borrowers authorize the Administrative
Agent (but the Administrative Agent shall not be obligated) to deduct from
said account, or any other account maintained by the Borrowers at the
Administrative Agent, any amount payable hereunder on or after the date upon
which it is due and payable.  Such authorization shall include but not be
limited to amounts payable with respect to principal, interest, fees and
expenses.

     (d)  NET PAYMENTS.  All payments made to the Banks by the Borrowers
hereunder, under any Note or under any other Loan Document will be made
without set off, counterclaim or other defense.

   2.13.  CHANGE IN CIRCUMSTANCES, YIELD PROTECTION.

     (a)  CERTAIN REGULATORY CHANGES.  If any Regulatory Change or compliance
by any Bank with any request made after the date of this Agreement by the
Board of Governors of the Federal Reserve System or by any Federal Reserve
Bank or other central bank or fiscal, monetary or similar authority (in each
case whether or not having the force of law) shall (i) impose, modify or make
applicable any reserve, special deposit, Federal Deposit Insurance
Corporation premium or similar requirement or imposition against assets held
by, or deposits in or for the account of, or loans made by, or any other
acquisition of funds for loans or advances by, any Bank; (ii) impose on any
Bank any other condition regarding the Notes; (iii) subject any Bank to, or
cause the withdrawal or termination of any previously granted exemption with
respect to, any tax (including any withholding tax but not including any
income tax not currently causing any Bank to be subject to withholding) or
any other levy, impost, duty, charge, fee or deduction on or from any
payments due from the Borrowers; or (iv) change the basis of taxation of
payments from the Borrowers to any Bank (other than by reason of a change in
the method of taxation of any Bank's net income); and the result of any of
the foregoing events is to increase the cost to any Bank of making or
maintaining any Loan or to reduce the amount of principal, interest or fees
to be received by any Bank hereunder in respect of any Loan, the
Administrative Agent will immediately so notify the Borrowers.  If any Bank
determines in good faith that the effects of the change resulting in such
increased cost or reduced amount cannot reasonably be avoided or the cost
thereof mitigated, then upon notice by the Administrative Agent to the
Borrowers, the Borrowers shall pay to such Bank on each interest payment date
of the Loan, such additional amount as shall be necessary to compensate that
Bank for such increased cost or reduced amount.

     (b)  CAPITAL ADEQUACY.  If any Bank shall determine that any Regulation
regarding capital adequacy or the adoption of any Regulation regarding
capital adequacy, which Regulation is applicable to banks (or their holding
companies) generally and not such Bank (or its holding company) specifically,
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by
such Bank (or its holding company) with any such request or directive
regarding capital adequacy (whether or not having the force of law) of any
such authority, central bank or comparable agency, has the effect of reducing
the rate of return on such Bank's capital as a consequence of its obligations
hereunder to a level below that which such Bank could have achieved but for
such adoption,


                                      31
<PAGE>

change or compliance (taking into consideration such Bank's policies with
respect to capital adequacy) by an amount deemed by such Bank to be material,
the Borrowers shall promptly pay to the Administrative Agent for the account
of such Bank, upon the demand of such Bank, such additional amount or amounts
as will compensate such Bank for such reduction.

     (c)  ABILITY TO DETERMINE LIBO RATE.  If the Administrative Agent shall
determine (which determination will be made after consultation with any Bank
requesting same and shall be, in the absence of fraud or manifest error,
conclusive and binding upon all parties hereto) that by reason of abnormal
circumstances affecting the interbank eurodollar or applicable eurocurrency
market adequate and reasonable means do not exist for ascertaining the LIBO
Rate to be applicable to the requested LIBO Rate Loan or that eurodollar or
eurocurrency funds in amounts sufficient to fund all the LIBO Rate Loans are
not obtainable on reasonable terms, the Administrative Agent shall give
notice of such inability or determination by telephone to the Borrowers and
to each Bank at least two Business Days prior to the date of the proposed
Loan and thereupon the obligations of the Banks to make, convert other Loans
to, or renew such LIBO Rate Loan shall be excused, subject, however, to the
right of the Borrowers at any time thereafter to submit another request.

     (d)  YIELD PROTECTION.  Determination by a Bank for purposes hereof of
the effect of any Regulatory Change or other change or circumstance referred
to in this Section 2.13 on its costs of making or maintaining Loans or on
amounts receivable by it in respect of the Loans and of the additional
amounts required to compensate such Bank in respect of any additional costs,
shall be made in good faith and shall be evidenced by a certificate, signed
by an officer of such Bank and delivered to the Borrowers, as to the fact and
amount of the increased cost incurred by or the reduced amount accruing to
such Bank owing to such event or events.  Such certificate shall be prepared
in reasonable detail and shall be conclusive as to the facts and amounts
stated therein, absent manifest error. The Borrowers shall pay such Bank the
amount shown as due at the times required herein.

     (e)  SYNDICATION COSTS.  If, within 180 days from the Closing Date, any
Agent incurs any breakage costs, charges or fees with respect to LIBO Rate
Loans on account of the syndication of this Credit Facility, the Borrowers
shall immediately reimburse such Agent for any such costs, charges or fees.
Such right of reimbursement is in addition to, and not in limitation of, any
other provisions of this Agreement.  The Borrowers shall pay such Agent the
amount shown as due on such notice within 10 days after its receipt of the
same.

     (f)  NOTICE OF EVENTS.  The affected Bank will notify the Borrowers of
any event occurring after the date of this Agreement that will entitle such
Bank to compensation pursuant to this Section as promptly as practicable
after it obtains knowledge thereof and determines to request such
compensation.  Said notice shall be in writing, shall specify the applicable
Section or Sections of this Agreement to which it relates and shall set forth
the amount or amounts then payable pursuant to this Section.

   2.14.  ILLEGALITY.  Notwithstanding any other provision in this Agreement,
if the adoption of any applicable Regulation, or any change therein, or any
change in the interpretation or


                                      32
<PAGE>

administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation or administration thereof,
or compliance by any Bank with any request or directive (whether or not
having the force of law) of any such authority, central bank, or comparable
agency shall make it unlawful or impossible for any Bank to (a) maintain its
Revolving Loan Commitment, then upon notice to the Borrowers by the
Administrative Agent, its Revolving Loan Commitment shall terminate; or (b)
maintain or fund its LIBO Rate Loans, then upon notice to the Borrowers of
such event, the Borrowers' outstanding LIBO Rate Loans shall be converted
into Base Rate Loans.

   2.15.  DISCRETION OF EACH BANK AS TO MANNER OF FUNDING.  Notwithstanding
any provision of this Agreement to the contrary, each Bank shall be entitled
to fund and maintain its funding of all or any part of its Loans in any
manner it sees fit, it being understood, however, that for the purposes of
this Agreement all determinations hereunder shall be made as if each Bank had
actually funded and maintained each LIBO Rate Loan during each Interest
Period for such Loan through the purchase of deposits in the relevant
interbank market having a maturity corresponding to such Interest Period and
bearing an interest rate equal to the LIBO Rate, for such Interest Period.

   2.16.  APPRAISALS.  Within 20 days following the receipt by the Banks of
the Borrowing Base Certificate covering the last month of a Fiscal Quarter,
the Majority Banks may request that an appraisal be conducted with respect to
Eligible Engines added to the Borrowing Base during the Fiscal Quarter just
ended.  The appraisal shall be a "desktop appraisal" (unless a Potential
Default or an Event of Default then exists) and shall be conducted by an
appraiser retained by the Appraisal Agent on behalf of the Banks, and the
cost of each such appraisal will be paid by the Borrowers. In addition to
paying the costs of the appraisals as aforesaid, for each year (measured from
the Closing Date), or part thereof, that this Agreement remains in effect or
that this Credit Facility remains available to the Borrowers, the Borrowers
shall also pay the Appraisal Agent an Appraisal Agent fee in consideration
for the Appraisal Agent's services under this Agreement.  The Appraisal Agent
fee shall be paid in advance on the first day of each such year, with the
initial Appraisal Agent fee payable on the Closing Date.

                3.  REPRESENTATIONS AND WARRANTIES

     Each of the Borrowers represents and warrants to the Banks that:

   3.1.   ORGANIZATION, STANDING.  It (a) is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of
its incorporation, (b) has the corporate power and authority necessary to own
its assets, carry on its business and enter into and perform its obligations
hereunder, and under each Loan Document to which it is a party, and (c) is
qualified to do business and is in good standing in each jurisdiction where
the nature of its business or the ownership of its properties requires such
qualification, except where the failure to be so qualified would not have a
Material Adverse Effect.

   3.2.   CORPORATE AUTHORITY, VALIDITY, ETC. The making and performance of
the Loan Documents to which it is a party are within its power and authority
and have been duly authorized by all necessary corporate action.  The making
and performance of the Loan


                                      33
<PAGE>

Documents do not and under present law will not require any consent or
approval not obtained of any of its shareholders, or any other person, do not
and under present law will not violate any law, rule, regulation order, writ,
judgment, injunction, decree, determination or award, do not violate any
provision of its charter or by-laws, do not and will not result in any breach

thereof are accurately set forth on Schedule 1 attached hereto; all such
shares are validly issued, fully paid and non-assessable, and the issuance
and sale thereof are in compliance with all applicable federal and state
securities and other applicable laws. Further, neither Borrower is in default
under any such agreement, lease or instrument except to the extent such
default reasonably could not have a Material Adverse Effect.  No
authorizations, approvals or consents of, and no filings or registrations
with, any governmental or regulatory authority or agency are necessary for
the execution, delivery or performance by the Borrowers of any Loan Document
to which it is a party or for the validity or enforceability thereof, except
any filings or registrations expressly contemplated by the Loan Documents.

reasonably could have a Material Adverse Effect.  If there is any disclosure
on Schedule 1, the status (including the tribunal, the nature of the claim
and the amount in controversy) of each such litigation matter as of the date
of this Agreement is set forth in Schedule 1.

   3.5.   ERISA.  (a) The Borrowers and each ERISA Affiliate are in
compliance in all material respects with all applicable provisions of ERISA
and the regulations promulgated thereunder; and, neither either Borrower, nor
any ERISA Affiliate maintains or contributes to or has maintained or
contributed to any multiemployer plan (as defined in Section  4001 of ERISA)
under which the Borrowers or any ERISA Affiliate could have any withdrawal
liability; (b) neither the Borrowers nor any ERISA Affiliate, sponsors or
maintains any Plan under which there is an accumulated funding deficiency
within the meaning of Section 412 of the Code, whether or not waived; (c) the
aggregate liability for accrued benefits and other ancillary benefits under
each Plan that is or will be sponsored or maintained by the Borrowers or any

prescribed for valuing benefits under terminating single-employer defined
benefit plans under Title IV of ERISA) does not exceed the aggregate fair
market value of the assets under each such defined benefit pension Plan; (d)
the aggregate liability of the Borrowers and each ERISA Affiliate arising out
of or relating to a failure of any Plan to comply with the provisions of
ERISA or the Code, will not have a Material Adverse Effect; and (e) there

herewith, present fairly, in all material respects, the financial position,
results of operations and operating statistics of the Borrowers as of the
dates and for the periods referred to, in conformity with GAAP.  Except as

contingent, which are not reflected in such financial statements, other than
liabilities which are not required to be reflected in such balance sheets.

   3.7.   NO MATERIAL ADVERSE CHANGE.  Since December 31, 1997, there has
been no Material Adverse Change.

   3.8.   NOT IN DEFAULT, JUDGMENTS, ETC.  No Event of Default or Potential
Default under any Loan Document has occurred and is continuing.  The
Borrowers have satisfied all judgments (other than judgments which do not

under any order, writ, injunction, or decree of any court, arbitrator, or
federal, state, municipal, or other governmental authority, commission, board
bureau, agency, or instrumentality, domestic or foreign.

   3.9.   TAXES.  The Borrowers have filed all federal, state, local and
foreign tax returns and reports which they are required by law to file and as
to which their failure to file would have a Material Adverse Effect, and have
paid all taxes, including wage taxes, assessments, withholdings and other
governmental charges which are presently due and payable, other than those
being contested in good faith by appropriate proceedings, if any, and

of the Borrowers are adequate to pay all such taxes that have accrued but are
not presently due and payable.

   3.10.  PERMITS, LICENSES, ETC.  The Borrowers possess all permits,
licenses, franchises, trademarks, trade names, copyrights and patents

   3.11.  NO MATERIALLY ADVERSE CONTRACTS, ETC. To the best of their
knowledge, the Borrowers are not subject to any charter, corporate or other
legal restriction, or any judgment, decree, order, rule or regulation which
in the judgment of their directors or officers has or is expected in the
future to have a Material Adverse Effect.  The Borrowers are not a party to
any contract or agreement which in the judgment of their directors or
officers has or is expected to have any Material Adverse Effect, except as
otherwise reflected in adequate reserves.

     (a)  COMPLIANCE GENERALLY.  The Borrowers are in compliance in all
material respects with all Regulations applicable to their business
(including obtaining all authorizations, consents, approvals, orders,
licenses, exemptions from, and making all filings or registrations or
qualifications with, any court or governmental department, public body or
authority, commission, board, bureau, agency, or instrumentality), the
noncompliance with which reasonably would likely have a Material Adverse

received all permits and filed all notifications necessary to carry on their
business; and are in compliance in all material respects with all
Environmental Control Statutes.  The Borrowers have not given any written or

Environmental Protection Agency ("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 them or used in connection with
the conduct of their business and operations.  The Borrowers have not
received notice that they are potentially responsible for costs of clean-up
or remediation of any actual or imminently threatened Release of Hazardous
Substances pursuant to any Environmental Control Statute.  To the best of the
Borrowers' knowledge, no real property owned or leased by them is in
violation of any Environmental Laws and no Hazardous Substances are present
on said real property in violation of applicable law.  The Borrowers have not
received any notice to the effect that they have been identified in any
litigation, administrative proceedings or investigation as a potentially
responsible party for any liability under any Environmental Laws.  In the
event that any Borrower becomes aware of any information indicating that
either (i) any real property owned or leased by any Borrower is in violation
of any Environmental Laws or any Hazardous Substances are present on said
real property in violation of applicable law, or (ii) any Borrower has been
identified in any litigation, administrative proceedings or investigation as
a potentially responsible party for liability under any Environmental Laws,
then the Borrowers shall update their representations, in accordance with the
requirements of Section 3.20, and the Banks shall not be required to make
further Loans or Standby Letters of Credit under this Credit Facility until
the Borrowers establish adequate reserves (in the reasonable judgment of the
Majority Banks) for any liability (including cleanup costs) and deliver
revised financial statements to the Banks showing such reserves; provided,
however, that no reserve shall be required for any such liabilities to the
extent that they aggregate to less than $1,000,000.

   3.13.  SOLVENCY.  The Borrowers are, and after giving effect to the
transactions contemplated hereby, will be, Solvent.

   3.14.  SUBSIDIARIES, ETC.  The Borrowers do not have any Subsidiaries,

Investments held by the Borrowers in any joint venture or other Person.

   3.15.  TITLE TO PROPERTIES, LEASES.  The Borrowers have good and
marketable title to all assets and properties reflected as being owned by
them in their financial statements as well as to all assets and properties
acquired since said date (except property disposed of since said date in the
ordinary course of business).  Except for the Liens set forth in Schedule 1
hereto and any


                                      36
<PAGE>

other Permitted Liens, there are no Liens on any of such assets or
properties.  They have the right to, and do, enjoy peaceful and undisturbed
possession under all material leases under which they are leasing property as
a lessee.  All such leases are valid, subsisting and in full force and
effect, and none of such leases is in default, except where such default,
either individually or in the aggregate, could not have a Material Adverse
Effect.

   3.16.  PUBLIC UTILITY HOLDING COMPANY; INVESTMENT COMPANY.  Neither Willis
nor WASI is a "public utility company" or a "holding company," or a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," as such terms
are defined in the Public Utility Holding Company Act of 1935, as amended; or
a "public utility" within the meaning of the Federal Power Act, as amended.
Further, neither Willis nor WASI is an "investment company" or an "affiliated
person" of an "investment company" or a company "controlled" by an
"investment company" as such terms are defined in the Investment Company Act
of 1940, as amended.

   3.17.  MARGIN STOCK.  The Borrowers are not and will not be engaged
principally or as one of their important activities in the business of
extending credit for the purpose of purchasing or carrying or trading in any
margin stocks or margin securities (within the meaning of Regulation U of the
Board of Governors of the Federal Reserve System as amended from time to
time).  Neither will they use or permit any proceeds of the Loans or Standby
Letters of Credit to be used, either directly or indirectly, for the purpose,
whether immediate, incidental or ultimate, of buying or carrying margin
stocks or margin securities.

   3.18.  USE OF PROCEEDS.  The Borrowers will use the proceeds of any Loan
or Standby Letter of Credit to be made pursuant hereto for the purchase and
refinancing of Equipment as contemplated herein, as well as for working
capital and general corporate purposes.

   3.19.  DEPRECIATION POLICIES.  The Borrowers' depreciation policies with
respect to the Equipment are as set forth on Exhibit H.  These policies have
been in effect substantially without change since January 1, 1997.

   3.20.  DISCLOSURE GENERALLY.  The representations and statements made by
the Borrowers or on their behalf in connection with this Credit Facility and
the Loans, including representations and statements in each of the Loan
Documents, do not and will not contain any untrue statement of a material
fact or omit to state a material fact or any fact necessary to make the
representations made not materially misleading.  No written information,
exhibit, report, brochure or financial statement furnished by the Borrowers
to the Banks in connection with this Credit Facility, the Loans, or any Loan
Document contains or will contain any material misstatement of fact or omit
to state a material fact or any fact necessary to make the statements
contained therein not misleading. Notwithstanding anything to the contrary in
this Agreement, the Disclosure Schedule (Schedule 1) to this Agreement shall
be promptly updated by the Borrowers whenever necessary to reflect events
that have occurred which would make the latest Disclosure Schedule delivered
by the Borrowers to the Banks inaccurate or misleading; provided, however,
that no updating of the Disclosure Schedule shall operate to:  (i) cure a
breach of a representation or warranty previously made by any Borrower or
Guarantor; (ii) modify any of the covenants or


                                      37
<PAGE>

obligations of any Borrower or Guarantor under this Agreement or any other
Loan Document (including any affirmative covenants, negative covenants or
financial covenants); (iii) prevent the occurrence of the disclosed event
from constituting a Potential Default or Event of Default if the occurrence
of such event otherwise constitutes a Potential Default or Event of Default
under this Agreement or any other Loan Document; or (iv) expand the
definitions of "Existing Debt" or "Permitted Liens" allowed under this
Agreement.

   3.21.  YEAR 2000.  The Borrowers have taken all action reasonably
necessary to assess the risk that the computer applications they use in their
business may be unable to properly perform date sensitive functions on or

                                       43
<PAGE>

long as the Borrowers first notify the Administrative Agent of their
intention to do so, they shall not be required to pay and discharge any such
Debt, tax, assessment, charge, levy or claim so long as the failure to so pay
or discharge does not constitute or result in an Event of Default or a
Potential Default hereunder and so long as no foreclosure or other similar
proceedings shall have been commenced against such property or any part
thereof and so long as the validity thereof shall be contested in good faith
by appropriate proceedings diligently pursued and they shall have set aside
on their books adequate reserves with respect thereto.

   5.9.   NOTICE OF EVENTS.  Promptly upon discovery of any of the following
events, the Borrowers shall provide telephone notice to the Administrative

declared by any party to such agreement or any event which, upon the lapse of
time or the giving of notice or both, would become an event of default under
any such agreement or instrument or would permit any party to any such
instrument or agreement to terminate or suspend any commitment to lend to the
Borrowers or to declare or to cause any such indebtedness to be accelerated
or payable before it would otherwise be due;

     (d)  the institution of, any material adverse determination in, or the
entry of any default judgment or order or stipulated judgment or order in,

out-of-pocket expense of such inspection; otherwise, such expenses shall be
chargeable pro rata to each Bank, in accordance with its  respective
Revolving Loan Commitment. At all times, it is understood and agreed by the

without the prior written consent of the Majority Banks, from and after the
date hereof and so long as any Revolving Loan Commitments or Term Loans are
in effect or any Obligation remains unpaid or outstanding, that:

existence of such excess, a prepayment of Loans (and, if necessary, a cash
collateralization of outstanding Standby Letters of Credit) shall be

                                       48

<PAGE>

made.  The Borrowers shall not be entitled to utilize this mechanism to avoid
a breach of this covenant more than two (2) times during any twelve-month

                                 8.  DEFAULT

     (c)  REPRESENTATIONS, WARRANTIES.  Any representation or warranty made
or deemed to be made by the Borrowers, as applicable, herein or in any Loan

     (e)  CERTAIN OTHER DEFAULTS.  The Borrowers shall fail to pay when due
any Indebtedness for Borrowed Money which singularly or in the aggregate
exceeds $1,000,000, and such failure shall continue beyond any applicable
cure period, or either Borrower shall suffer to exist any default or event of
default in the performance or observance, subject to any applicable grace
period, of any agreement, term, condition or covenant with respect to any
agreement or document relating to Indebtedness for Borrowed Money if the
effect of such default is to permit, with the giving of notice or passage of
time or both, the holders thereof, or any trustee or agent for said holders,
to terminate or suspend any commitment (which is equal to or in excess of
$1,000,000) to lend money or to cause or declare any portion of any
borrowings thereunder to

                                      49

     (h)  CHANGE IN CONTROL OF EITHER BORROWER. Any Change of Control of
either Borrower should occur.

     (i)  SECURITY INTERESTS.  Except for security interests (a) in
Collateral listed on Schedule 2 hereto; (b) in Equipment which the
Administrative Agent determines to include in the Borrowing Base as part of
the $10,000,000 basket for unperfected Collateral or which is specifically
approved in writing by the Majority Banks notwithstanding that the
Administrative Agent will not receive a perfected first priority security
interest therein; (c) in Collateral as to which the Administrative Agent
fails to file a UCC continuation statement; and (d) in Collateral (other than
Equipment) as to which perfection is effected by any means other than by
filing a UCC-1 financing statement (the Collateral described in (a), (b), and
(d) above is hereinafter referred to as the "Excepted Collateral"), any
security interest created pursuant to any Loan Document shall cease to be in
full force and effect, or shall cease in any material respect to give the
Administrative Agent the Liens, rights, powers and privileges purported to be
created thereby (including, without limitation, a perfected security interest
in, and Lien on, all of the Collateral), superior to and prior to the rights
of all third Persons, and subject to no other Liens (except as permitted by
Section 6.2).

THEN and in every such event other than that specified in Section 8.1(d),

amount of all outstanding Standby Letters of Credit shall be paid in cash to
the Administrative Agent as additional Collateral for the Obligations, and
the Notes, including without limitation accrued interest, shall immediately
be due and payable without presentment, demand, protest or other notice of
any kind, all of which are hereby expressly waived by the Borrowers.  Any
date on which the Notes and such other Obligations are declared due and
payable pursuant to this Section 8.1, shall be the Facility Termination Date
for purposes of this

                                      50
<PAGE>

Agreement.  From and after the date an Event of Default shall have occurred

   9.1.   COLLATERAL.  Except as otherwise specifically set forth herein
(including but not limited to the exceptions contained in Section 8.1(i)) or
in any other Loan Document, any Obligations made and outstanding and their
repayment at all times shall (a) in the case of Collateral (as defined in the
Security Agreement, hereinafter referred to as the "COLLATERAL") located in
the United States, be secured by a first priority perfected security
interest; and (b) in the case of Collateral located in jurisdictions outside
the United States, be secured by a security interest which adequately
protects the first priority security interest in favor of the Administrative
Agent.

   9.2.   SECURITY DOCUMENTS.  As security for the punctual payment in full
of all Notes (including all payments of principal, and interest and other
costs contemplated hereby) and Standby Letters of Credit, the Borrowers shall

Amendment No. 3 to Mortgage and such other documents as may be necessary to
constitute and evidence and perfect a security interest in the Collateral
(other than the Excepted Collateral); PROVIDED, however, that if a Potential
Default or Event of Default exists, the Administrative Agent may require the
Borrowers to take all action possible to further legally perfect the security
interest in all assets of the Borrowers, except as otherwise provided in the
Loan Documents, but INCLUDING Excepted Collateral.

   9.3.   RELEASE OF COLLATERAL. The Borrowers shall be entitled to remove
and request the Administrative Agent to release certain items of Collateral
in accordance with the provisions of Section 5(a) of the Security Agreement.
The Administrative Agent will cooperate with the Borrowers in effecting any
such release.

                                10.  THE AGENTS

   10.1.  APPOINTMENT AND AUTHORIZATION.  Each Bank hereby irrevocably
appoints and authorizes First Union as the Administrative Agent, NMS as the
Syndication Agent and NationsBank as the Appraisal Agent to take such action
on each Bank's behalf and to exercise such powers under this Agreement and
the Loan Documents as are specifically delegated to the Agents by the terms
hereof or thereof, together with such other powers as are reasonably
incidental thereto. No other agents or co-agents of the Banks under this
Credit Facility may be appointed without the prior written consent of First
Union and NationsBank.  The relationship between each Agent and each Bank has
no fiduciary aspects, and each Agent's duties hereunder are acknowledged to
be only ministerial and not involving the exercise of discretion on its part.
Nothing in this Agreement or any Loan Document shall be construed to impose
on any Agent any duties or responsibilities other than those for which
express provision is made herein or therein.  In performing their duties and
functions under this Article 10, the Agents do not assume and shall not be
deemed to have assumed, and hereby expressly disclaim, any obligation with or
for the Borrowers.  As to matters not expressly provided for in this
Agreement or any Loan Document, the Agents shall not be required to exercise
any discretion or to take any action or communicate any notice, but shall be
fully protected in so acting or refraining from acting upon

                                       51
<PAGE>

the instructions of the Majority Banks and their respective successors and
assigns; provided, however, that in no event shall any Agent be required to
take any action which exposes it to personal liability or which is contrary
to this Agreement, any Loan Document or applicable law, and each Agent shall
be fully justified in failing or refusing to take any action hereunder unless
it shall first be specifically indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by
reason of taking or omitting to take any such action.  If an indemnity
furnished to any Agents for any purpose shall, in its reasonable opinion, be
insufficient or become impaired, such Agent may call for additional indemnity
from the Banks and not commence or cease to do the acts for which such
indemnity is requested until such additional indemnity is furnished.

   10.2.  DUTIES AND OBLIGATIONS.  In performing its functions and duties
hereunder on behalf of the Banks, each Agent shall exercise the same care and
skill as it would exercise in dealing with loans for its own account.
Neither Agent, nor any of its directors, officers, employees or other agents
shall be liable for any action taken or omitted to be taken by it or them
under or in connection with this Agreement or any Loan Document except for
its or their own gross negligence or willful misconduct.  Without limiting
the generality of the foregoing, each Agent (a) may consult with legal
counsel and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith and in accordance
with the advice of such experts; (b) makes no representation or warranty to
any Bank as to, and shall not be responsible to any Bank for, any recital,
statement, representation or warranty made in or in connection with this
Agreement, any Loan Document or in any written or oral statement (including a
financial or other such statement), instrument or other document delivered in
connection herewith or therewith or furnished to any Bank by or on behalf of
the Borrowers; (c) shall have no duty to ascertain or inquire into the
Borrowers' performance or observance of any of the covenants or conditions
contained herein or to inspect any of the property (including the books and
records) of the Borrowers or inquire into the use of the proceeds of the
Revolving Loans or Term Loans or (unless the officers of the Agent active in
their capacity as officers of such Agent on the Borrowers' account have
actual knowledge thereof or have been notified in writing thereof) to inquire
into the existence or possible existence of any Event of Default or Potential
Default; (d) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, effectiveness, genuineness, sufficiency,
collectibility or value of this Agreement or any other Loan Document or any
instrument or document executed or issued pursuant hereto or in connection
herewith, except to the extent that such may be dependent on the due
authorization and execution by the Agent itself; (e) except as expressly
provided herein in respect of information and data furnished to any Agent for
distribution to the Banks, shall have no duty or responsibility, either
initially or on a continuing basis, to provide to any Bank any credit or
other information with respect to the Borrowers, whether coming into its
possession before the making of the Loans or at any time or times thereafter;
and (f) shall incur no liability under or in respect of this Agreement or any
other Loan Document for, and shall be entitled to rely and act upon, any
notice, consent, certificate or other instrument or writing (which may be by
facsimile (telecopier), telegram, cable, or other electronic means) believed
by it to be genuine and correct and to have been signed or sent by the proper
party or parties.

   10.3.  THE AGENTS AS BANKS.  With respect to its Revolving Loan Commitment
and the Loans made and to be made by it, each Agent shall have the same
rights and powers under this Agreement and all other Loan Documents as the
other Banks and may exercise the same as if it were not an Agent.  The terms
"Bank" and "Banks" as used herein shall, unless otherwise expressly
indicated, include First Union and NationsBank in their individual capacity.
First Union and any successor Administrative Agent, and NationsBank and any
successor Appraisal Agent, which is a commercial bank, and their respective
affiliates, may accept deposits from, lend money to, act as trustee under
indentures of and generally engage in any kind of business with, the
Borrowers and their affiliates from time to time, all as if such entity were
not the Administrative Agent or Appraisal Agent hereunder and without any
duty to account therefor to any Bank.

   10.4.  INDEPENDENT CREDIT DECISIONS.  Each Bank acknowledges to the Agents
that it has, independently and without reliance upon the Agents or any other
Bank, and based upon such documents and information as it has deemed
appropriate, made its own independent credit analysis and decision to enter
into this Agreement.  Each Bank also acknowledges that it will, independently
or through other advisers and representatives but without reliance upon the
Agents or any other Bank, and based upon such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions
in taking or refraining from taking any action under this Agreement or any
Loan Document.

   10.5.  INDEMNIFICATION.  The Banks agree to indemnify each Agent (to the
extent not previously reimbursed by the Borrowers), ratably in proportion to
each Bank's Revolving Loan Commitment Percentage, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses and disbursements of any kind or nature whatsoever
which may be imposed on, incurred by or asserted against First Union in its
capacity as Administrative Agent, or against NationsBank in its capacity as
Appraisal Agent, in any way relating to or arising out of this Agreement or
any Loan Document or any action taken or omitted to be taken by First Union
in its capacity as Administrative Agent, or NationsBank in its capacity as
Appraisal Agent, hereunder or under any Loan Document; provided that none of
the Banks shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from any Agent's gross negligence or willful
misconduct.  Without limiting the generality of the foregoing, each Bank
agrees to reimburse the Agents, promptly on demand, for such Bank's ratable
share (based upon the aforesaid apportionment) of any out-of-pocket expenses
(including counsel fees and disbursements) incurred by such Agent in
connection with the preparation, execution, administration or enforcement of,
or the preservation of any rights under, this Agreement and the Loan
Documents to the extent that such Agent is not reimbursed for such expenses
by the Borrowers.

   10.6.  SUCCESSOR AGENTS. The Syndication Agent or the Appraisal Agent may
resign upon 30 days written notice to the Borrowers and the Administrative
Agent.  Any Agent may resign at any time by giving written notice of such
resignation to the Banks and the Borrowers, such resignation to be effective
only upon the appointment of a successor Agent as hereinafter provided.  Upon
any such notice of resignation, the Banks shall jointly appoint a successor
Agent

                                      53
<PAGE>

upon written notice to the Borrowers and the withdrawing Agent, and provided
that no Potential Default or Event of Default exists, the Borrowers shall
have the right to consent to such appointment (which consent shall not be
unreasonably withheld or delayed).  If no successor Agent shall have been
jointly appointed by such Banks (and, if required, consented to by the
Borrowers) and shall have accepted such appointment within thirty (30) days
after the withdrawing Agent shall have given notice of resignation, the
Administrative Agent may, upon notice to the Borrowers and the Banks, appoint
a successor Agent.  Upon its acceptance of any appointment as Agent
hereunder, the successor Agent shall succeed to and become vested with all
the rights, powers, privileges and duties of its predecessor, and the
withdrawing Agent shall be discharged from its duties and obligations as
Agent under this Agreement and the Loan Documents.  After an Agent's
resignation hereunder, the provisions hereof shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was the Agent under
this Agreement and the Loan Documents.

   10.7.  ALLOCATIONS MADE BY THE ADMINISTRATIVE AGENT.  As between the
Administrative Agent and the Banks, unless a Bank objecting to a
determination or allocation made by the Administrative Agent pursuant to this
Agreement delivers to the Administrative Agent written notice of such
objection within one hundred twenty (120) days after the date any
distribution was made by the Administrative Agent, such determination or
allocation shall be conclusive on such one hundred twentieth day and only
those items expressly objected to in such notice shall be deemed disputed by
such Bank.  The Administrative Agent shall not have any duty to inquire as to
the application by the Banks of any amounts distributed to them.

                              11.  MISCELLANEOUS

   11.1.  WAIVER.  No failure or delay on the part of any Agent or any Bank
or any holder of any Note in exercising any right, power or remedy under any
Loan Document shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right, power or remedy preclude any other or
further exercise thereof or the exercise of any other right, power or remedy
under any Loan Document.  The remedies provided under the Loan Documents are
cumulative and not exclusive of any remedies provided by law.

   11.2.  AMENDMENTS.  No amendment, modification, termination, renewal or
waiver of any Loan Document or any provision thereof nor any consent to any
departure by the Borrowers therefrom shall be effective unless the same shall
have been approved by the Majority Banks, be in writing and be signed by
First Union, as Administrative Agent on behalf of the Banks, and then any
such waiver or consent shall be effective only in the instance and for the
specific purpose for which given, provided, however, that unanimous written
consent of all of the Banks shall be required for:  (a) any increase in the
amount of the Aggregate Revolving Loan Commitment; (b) any reduction in
principal, interest, or fees payable by Borrowers under this Credit Facility;
(c) any extension of the Revolving Loan Termination Date or the maturity
dates of any Term Loans; (d) any extension of the due date for payment of any
principal, interest or fees to be collected on behalf of the Banks; (e) any
release of all or substantially all of the Collateral (PROVIDED, however,
that the Administrative Agent, acting alone, shall be entitled to release
less than all or substantially all of the Collateral pursuant to Section
9.3); or (f) the release of

                                      54

<PAGE>

any Guarantor.  In addition to the foregoing, no modification to the
definition of "Borrowing Base" shall be made without the written consent of
the Required Banks, and none of the voting rights established under this
Section 11.2 shall be modified without the written consent of that number of
Banks which would have been required to take the action to which such voting
rights apply.  No notice to or demand on the Borrowers shall entitle the
Borrowers to any other or further notice or demand in similar or other
circumstances.  No amendment or modification affecting the role of any Agent
or Agents shall be effective unless it has been approved in writing by such
Agent or Agents, as applicable.

   11.3.  GOVERNING LAW.  The Loan Documents and all rights and obligations
of the parties thereunder shall be governed by and be construed and enforced
in accordance with the laws of the State of California without regard to
California or federal principles of conflict of laws.

   11.4.  PARTICIPATIONS AND ASSIGNMENTS. The Borrowers hereby acknowledge
and agree that so long as a Bank is not in default of its obligations under
this Agreement, such Bank may at any time, with the consent (which consent
shall not be unreasonably withheld) of the Borrowers and the Administrative
Agent and the Appraisal Agent: (a) grant participations in all or any portion
of its Revolving Loan Commitment or any portion of its Note(s) or of its
right, title and interest therein or in or to this Agreement (collectively,
"PARTICIPATIONS") to any other lending office of such Bank or to any other
bank, lending institution or other entity which has the requisite
sophistication to evaluate the merits and risks of investments in
Participations ("PARTICIPANTS"); provided, however, that:  (i) all amounts
payable by the Borrowers hereunder shall be determined as if such Bank had
not granted such Participation; (ii) such Bank shall act as agent for all
Participants; and (iii) any agreement pursuant to which such Bank may grant a
Participation: (x) shall provide that such Bank shall retain the sole right
and responsibility to enforce the obligations of the Borrowers hereunder
including, without limitation, the right to approve any amendment,
modification or waiver of any provisions of this Agreement; (y) such
participation agreement 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 reduce the
principal of or rate of interest on any Loan or postpone the date fixed for
any payment of principal of or interest on any Loan; and (z) shall not
relieve such Bank from its obligations, which shall remain absolute, to make
Loans hereunder; and (b) assign any of its Loans and its Revolving Loan
Commitment. Upon execution and delivery by the assignee to the Borrowers of
an instrument in writing pursuant to which such assignee agrees to become a
"Bank" hereunder having the Revolving Loan Commitment and Loans specified in
such instrument, and upon consent thereto by the Borrowers and the
Administrative Agent and the Appraisal Agent, to the extent required above,
the assignee shall have, to the extent of such assignment (unless otherwise
provided in such assignment with the consent of the Borrowers), the
obligations, rights and benefits of a Bank hereunder holding the Revolving
Loan Commitment and Loans (or portions thereof) assigned to it, and such Bank
shall, to the extent of such assignment, be released from the Revolving Loan
Commitment (or portion(s) thereof) so assigned.  An Assignment Fee of $3,500
shall be paid by the assigning Bank to the Administrative Agent upon
consummation of any assignment, including an assignment from one Bank to
anothe Bank.  No assignments will be permitted by a Bank at a time when such
Bank is in default of its obligations under this Agreement.  Notwithstanding
anything to the contrary in


                                      55
<PAGE>

this Section 11.4, the Borrowers shall not have the right to approve any
assignment or Participation by a Bank if a Potential Default or an Event of
Default then exists.

   11.5.  CAPTIONS.  Captions in the Loan Documents are included for
convenience of reference only and shall not constitute a part of any Loan
Document for any other purpose.

   11.6.  NOTICES.  All notices, requests, demands, directions, declarations
and other communications between the Banks and the Borrowers provided for in
any Loan Document shall, except as otherwise expressly provided, be mailed by
registered or certified mail, return receipt requested, or telegraphed, or
faxed, or delivered in hand or by a nationally recognized overnight courier
to the applicable party at its address indicated opposite its name on the
signature pages hereto.  The foregoing shall be effective and deemed received
three days after being deposited in the mails, postage prepaid, addressed as
aforesaid and shall whenever sent by telegram, telegraph or facsimile
(provided the transmitting facsimile machine provides written confirmation
that the transmission was successfully completed) or delivered in hand or by
a nationally recognized overnight courier be effective when received.  Any
party may change its address by a communication in accordance herewith.

   11.7.  SHARING OF COLLECTIONS, PROCEEDS AND SET-OFFS: APPLICATION OF
PAYMENTS.

     (a)  If any Bank, by exercising any right of set-off, counterclaim or
foreclosure, receives payment of principal or interest or other amount due on
any Note which is greater than the percentage share of such Bank (determined
as set forth below), the Bank receiving such proportionately greater payment
shall purchase such participations in the Loans held by the other Banks, and
such other adjustments shall be made as may be required, so that all such
payments shall be shared by the Banks on the basis of their percentage
shares; provided that if all or any portion of such proportionately greater
payment of such indebtedness is thereafter recovered from, or must otherwise
be restored by, such purchasing Bank, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest
being paid by such purchasing Bank.  The percentage share of each Bank shall
be based on the portion of the outstanding Loans of such Bank (prior to
receiving any payment for which an adjustment must be made under this
Section) in relation to the aggregate outstanding Loans of all the Banks.
The Borrowers agree, to the fullest extent they may effectively do so under
applicable law, that any holder of a participation in a Loan or reimbursement
obligation, whether or not acquired pursuant to the foregoing arrangements,
may exercise rights of set-off or counterclaim and other rights with respect
to such participation as fully as if such holder of a participation were a
direct creditor of the Borrowers in the amount of such participation.  If
under any applicable bankruptcy, insolvency or other similar law, any Bank
receives a secured claim in lieu of a set-off to which this Section would
apply, such Bank shall, to the extent practicable, exercise its rights in
respect of such secured claim in a manner consistent with the rights of the
Banks entitled under this Section to share in the benefits of any recovery on
such secured claim.

     (b)  If an Event of Default or Potential Default shall have occurred and
be continuing the Agents, each Bank and the Borrowers agree that all payments
on account of the Obligations shall be applied by the Administrative Agent
and the Banks as follows:


                                      56
<PAGE>

     FIRST, to First Union, as Administrative Agent, for any Administrative
Agent fees then due and payable under this Agreement until such fees are paid
in full;

     SECOND, to any Agent, for any fees, costs or expenses (including
expenses described in Section 11.8) incurred by such Agent, under any of the
Loan Documents or this Agreement, then due and payable and not reimbursed by
the Borrowers or the Banks until such fees, costs and expenses are paid in
full;

     THIRD, to the Banks for their percentage shares of the Revolving Loan
Commitment Fee then due and payable under this Agreement until such fee is
paid in full;

     FOURTH, to the Banks for their respective shares of all costs, expenses
and fees, including Standby Letter of Credit fees, then due and payable from
the Borrowers until such costs, expenses and fees are paid in full;

     FIFTH, to the Banks for their percentage shares of all interest then due
and payable from the Borrowers until such interest is paid in full, which
percentage shares shall be calculated by determining each Bank's percentage
share of the amounts allocated in (a) above determined as set forth in said
clause (a); and

     SIXTH, to the Banks for their percentage shares of the principal amount
of the Obligations then due and payable from the Borrowers until such
principal is paid in full, which percentage shares shall be calculated by
determining each Bank's percentage share of the amounts allocated in (a)
above determined as set forth in said clause (a).

   11.8.  EXPENSES; INDEMNIFICATION.  The Borrowers will from time to time
reimburse the Agents promptly following demand for all reasonable
out-of-pocket expenses (including the reasonable fees and expenses of their
legal counsel) in connection with (a) the preparation of the Loan Documents,
(b) the making of any Loans, (c) the administration of the Loan Documents,
and (d) the syndication of this Credit Facility.  The Borrowers also will
from to time reimburse the Agents and each Bank for all out-of-pocket
expenses (including reasonable fees and expenses of their legal counsel) in
connection with the enforcement of the Loan Documents.  In addition to the
payment of the foregoing expenses, the Borrowers hereby agree to indemnify,
defend, protect and hold First Union, as Administrative Agent, NationsBank,
as Appraisal Agent, and NMS, as Syndication Agent, each Bank and any holder
of any Note and the officers, directors, employees, agents, affiliates and
attorneys of the Agents, each Bank and such holder (collectively, the
"INDEMNITEES") harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses and disbursements of any kind or nature, including reasonable fees
and expenses of legal counsel, which may be imposed on, incurred by, or
asserted against such Indemnitee by the Borrowers or other third parties and
arise out of or relate to this Agreement or the other Loan Documents or any
other matter whatsoever related to the transactions contemplated by or
referred to in this Agreement or the other Loan Documents; provided, however,
that the Borrowers shall have no obligation to an Indemnitee hereunder to the
extent that the liability incurred by such Indemnitee has been determined by
a court of competent jurisdiction to be the result of gross negligence or
willful misconduct of such Indemnitee.


                                      57

   11.9.  SURVIVAL OF WARRANTIES AND CERTAIN AGREEMENTS.  All agreements,
representations and warranties expressly made herein shall survive the
execution and delivery of this Agreement, the making of the Loans hereunder
and the execution and delivery of the Notes.  Notwithstanding anything in
this Agreement or implied by law to the contrary, the agreements of the
Borrowers set forth in Section 11.8 shall survive the payment of the Loans
and the termination of this Agreement.  This Agreement shall remain in full
force and effect until the repayment in full of all amounts owed by the
Borrowers under the Notes or any other Loan Document.

   11.10. SEVERABILITY.  The invalidity, illegality or unenforceability in
any jurisdiction of any provision in or obligation under this Agreement, any
Note or other Loan Document shall not affect or impair the validity, legality
or enforceability of the remaining provisions or obligations under this
Agreement, the Notes or other Loan Documents or of such provision or
obligation in any other jurisdiction.

   11.11. BANKS' OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF BANKS' RIGHTS.
The obligation of each Bank hereunder is several and not joint and no Bank
shall be the agent of any other (except to the extent any Agent is authorized
to act as such hereunder).  No Bank shall be responsible for the obligation
or commitment of any other Bank hereunder.  In the event that any Bank at any
time should fail to make a Loan as herein provided, the other Banks, or any
of them as may then be agreed upon, at their sole option, may make the Loan
that was to have been made by the Bank so failing to make such Loan.  Nothing
contained in any Loan Document and no action taken by any Agent or any Bank
pursuant hereto or thereto shall be deemed to constitute the Banks to be a
partnership, an association, a joint venture or any other kind of entity.
The amounts payable at any time hereunder to each Bank shall be a separate
and independent debt, and, subject to the terms of this Agreement, each Bank
shall be entitled to protect and enforce its rights arising out of this
Agreement and it shall not be necessary for any other Bank to be joined as an
additional party in any proceeding for such purpose.

   11.12. NO FIDUCIARY RELATIONSHIP.  No provision in this Agreement or in
any of the other Loan Documents and no course of dealing between the parties
shall be deemed to create any fiduciary duty by any Bank to the Borrowers.

   11.13. CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  THE BORROWERS, THE
AGENTS, AND THE BANKS, EACH HEREBY CONSENT TO THE JURISDICTION OF ANY STATE
OR FEDERAL COURT LOCATED WITHIN THE EASTERN DISTRICT OF PENNSYLVANIA AND
IRREVOCABLY AGREES THAT, ANY ACTIONS OR PROCEEDINGS ARISING OUT OF OR
RELATING TO THE NOTE, THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS MAY BE
LITIGATED IN SUCH COURTS.  EACH PARTY TO THIS AGREEMENT ACCEPTS FOR ITSELF
AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE
NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF
FORUM NON CONVENIENT, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
RENDERED THEREBY IN CONNECTION WITH THIS AGREEMENT, ANY NOTE, OR SUCH OTHER
LOAN DOCUMENT.


                                      58
<PAGE>

   11.14. WAIVER OF JURY TRIAL.  THE BORROWERS, THE AGENTS, AND THE BANKS,
EACH HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE LOAN
DOCUMENTS, OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF
THIS AGREEMENT AND THE LENDER/BORROWER RELATIONSHIP ESTABLISHED HEREBY.  THE
SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL
DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER
OF THIS TRANSACTION, INCLUDING WITHOUT LIMITATION, CONTRACT CLAIMS, TORT
CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.
 THE BORROWERS, THE AGENTS, AND THE BANKS, EACH ACKNOWLEDGES THAT THIS WAIVER
IS A MATERIAL INDUCEMENT TO THE TRANSACTION, THAT EACH HAS ALREADY RELIED ON
THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH WILL CONTINUE TO
RELY ON THE WAIVER IN THEIR RELATED FUTURE DEALINGS.  THE BORROWERS, THE
AGENTS, AND THE BANKS EACH FURTHER WARRANTS AND REPRESENTS THAT EACH HAS
REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND
VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL
COUNSEL.  THIS WAIVER IS IRREVOCABLE, AND THE WAIVER SHALL APPLY TO ANY
SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS, MODIFICATIONS, REPLACEMENTS OR
RESTATEMENTS TO THIS AGREEMENT, THE LOAN DOCUMENTS, OR TO ANY OTHER DOCUMENTS
OR AGREEMENTS RELATING TO THE LOANS.  IN THE EVENT OF LITIGATION, THIS
AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

   11.15. COUNTERPARTS; EFFECTIVENESS.  This Agreement and any amendment
hereto or waiver hereof may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument.  This Agreement and any amendments
hereto or waivers hereof shall become effective when the Administrative Agent
shall have received signed counterparts or notice by fax of the signature
page that the counterpart has been signed and is being delivered to it or
facsimile that such counterparts have been signed by all the parties hereto
or thereto.

   11.16. USE OF DEFINED TERMS.  All words used herein in the singular or
plural shall be deemed to have been used in the plural or singular where the
context or construction so requires.  Any defined term used in the singular
preceded by "any" shall be taken to indicate any number of the members of the
relevant class.

   11.17. OFFSETS.  Nothing in this Agreement shall be deemed a waiver or
prohibition of any Bank's right of banker's lien or offset.

   11.18. ENTIRE AGREEMENT.  This Agreement, the Notes issued hereunder and
the other Loan Documents constitute the entire understanding of the parties
hereto as of the date hereof with


                                      59
<PAGE>

respect to the subject matter hereof and thereof and supersede any prior
agreements, written or oral, with respect hereto or thereto.

   11.19. CONFIDENTIALITY.  In handling any written information specifically
marked "confidential" prior to its delivery to any Bank by the Borrowers,
each of the Agents and the Banks shall exercise the same degree of care that
it exercises with respect to its own proprietary information of the same type
to maintain the confidentiality of any non-public information thereby
received or received pursuant to this Agreement or any other Loan Documents
except that disclosure of such information may be made (a) to the agents,
employees, subsidiaries or affiliates of such Person in connection with this
Agreement or any other Loan Document, (b) to prospective participants or
assignees of the Loans, provided that they have agreed to be bound by the
provisions of this Section 11.19, (c) as required by law, regulation, rule or
order, subpoena, judicial order or similar order, and (d) as may be required
in connection with the examination, audit or similar investigation of such
Person.  Confidential information shall not include information that either
(x) is in the public domain, or becomes a part of the public domain after
disclosure to such Person through no fault of such Person or (y) is disclosed
to such Person by a third party, provided such Person does not have knowledge
that such third party is prohibited from disclosing such information.


                                      60

     IN WITNESS WHEREOF, the parties hereto have each caused this Agreement to
