Note D - Acquisition of Net Assets of Nuclear Cooling, Inc.

      Effective February 1, 1998, Engineered Coil Company, a wholly-owned
subsidiary of Engineered Support Systems, Inc., acquired substantially all of
the net assets of Nuclear Cooling, Inc., d/b/a Marlo Coil, a manufacturer of
heat transfer and air movement equipment, from an investor group for
approximately $25.3 million.  The fair value of assets acquired, including
goodwill of $16.9 million, was $31.0 million and liabilities assumed totaled

Note E - Subsequent Event (Acquisition of Keco Industries, Inc.)

      On May 15, 1998, the Company agreed to acquire the common stock of Keco
Industries, Inc. (Keco), a manufacturer of military ground support equipment.
This transaction is contingent upon receiving government approval under the
Hart Scott Rodino Act.

      For the fiscal year ended December 31, 1997, sales of Keco were
approximately $42 million and assets, which consist primarily of
manufacturing facilities and working capital, were $18.4 million.  The
purchase price was $25.0 million.  (The Stock Purchase Agreement also
provides for an additional payment by the Company if it elects treatment of
the transaction pursuant to Section 338(h)(10) of the Internal Revenue Code).
The purchase price will be financed with bank borrowings of $22.5 million and
available cash resources.  Further details of the transaction will be
provided in Form 8-K to be filed with the Securities and Exchange Commission.

Note F - Subsequent Event (Stock Split)

      On May 21, 1998, the Company's Board of Directors approved a
three-for-two stock split, which will be effected in the form of a 50% stock
dividend. The new shares will be distributed on June 26, 1998 to shareholders of
record as of the close of business on June 12, 1998.

                       ENGINEERED SUPPORT SYSTEMS, INC.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

      Revenues increased 1% in the second quarter of 1998 to $23.0 million
from $22.9 million in the second quarter of 1997, and decreased 10% to $39.2
million in the first six months of 1998 from $43.6 million in the first half
of 1997.  Revenues for the second quarter of 1998 were favorably impacted by
the Marlo Coil acquisition (see Note D) which was effective February 1, 1998.
Revenues for Engineered Air Systems, Inc. (Engineered Air) decreased 47% and
35%, respectively, for the three and six month periods ended April 30, 1998.
This decrease was a result of lower shipments of production items as several
major contracts, primarily the Chemical/Biological Protected Shelter System
(CBPSS) and the Chemically/Biologically Hardened Air Management Plan (CHAMP),
are in the engineering and development phase.  Engineered Specialty Plastics,
Inc. (ESP) posted its highest quarterly revenues ever in the three months
ended April 30, 1998, up 6% from the second quarter of 1997.  For the
year-to-date, however, ESP's revenues were 6% lower than those generated in
1997 due to a reduction in shipments of houseware products in November and
December 1997.

      Gross profit for the second quarter of 1998 increased $2.0 million, or
54%, over the amount for the comparable 1997 period.  This increase is
primarily the result of significant margin expansion at ESP (due to increased
volume) and at Engineered Air (due to a more profitable mix of contracts), as
well as the addition of Marlo Coil which generates gross margins
significantly above those provided by the other two subsidiaries.  The gross
margin for the second quarter was 24.5% and 16.1% in 1998 and 1997,
respectively.  The gross margin for the first six months of the year was
22.8% and 15.6% in 1998 and 1997, respectively.

      Selling, general and administrative expense was $3.1 million and $1.9
million in the second quarter of 1998 and 1997, respectively.  This increase
was due to the addition of Marlo Coil.  As a percentage of net revenues,
selling, general and administrative expense increased from 8.1% in the second
quarter of 1997 to 13.3% in 1998.  For the six months ended April 30, 1998,
this percentage was 12.5% compared to 8.3% for the first half of 1997.

      Interest expense increased $390,000 in the second quarter of 1998 as
compared with the second quarter of 1997.  This increase was a result of the
$25.3 million Marlo Coil acquisition, which was financed with $22.5 million
of bank term debt and $2.8 million of available cash resources.  However,
strong operational cash flow at all three subsidiaries partially offset the
impact of the acquisition on interest expense.

Liquidity and Capital Resources

      At April 30, 1998, the Company's working capital and ratio of current
assets to current liabilities were $12.5 million and 1.83 to 1 as compared to
$11.6 million and 2.34 to 1 at October 31, 1997.  As of April 30, 1998, the
Company had cash and cash equivalents of $6.1 million and unused credit
related to its loan agreement of $5.0 million.

                                    9
<PAGE> 10

      As discussed in Note E, the Company has agreed to acquire Keco
Industries, Inc. (Keco), a manufacturer of military ground support equipment.
The purchase price will be financed with $22.5 million of bank term debt and
available cash resources.  The Company believes that cash flow generated from
operations will provide the necessary resources to meet the needs of the
Company in the foreseeable future, including debt service on bank borrowings
associated with the Marlo Coil and Keco acquisitions.

Business and Market Considerations

      Approximately 55% of consolidated net revenues for the six months ended
April 30, 1998 were derived from defense orders by the U.S. government and
its agencies.  (This percentage will increase following the completion of the
Keco acquisition.)  As of April 30, 1998, the Company's combined backlog of
defense orders at Engineered Air and Marlo Coil totaled $61.3 million, with
related government options of an additional $139.4 million.

      Management continues to pursue potential acquisitions, primarily of
those companies providing strategic consolidation within the defense
industry.

related reimbursement obligations.  The Borrower promises to reimburse the
Issuing Lender on the day of drawing under any Letter of Credit (either with
the proceeds of a Revolving Loan obtained hereunder or otherwise) in same day
funds.  If the Borrower shall fail to reimburse the Issuing Lender as
provided hereinabove, the unreimbursed amount of such drawing shall bear
interest at a per annum rate equal to the Adjusted Base Rate plus 2%.  The
Borrower's reimbursement obligations hereunder shall be absolute and
unconditional under all circumstances irrespective of any rights of setoff,
counterclaim or defense to payment the Borrower may claim or have against the
Issuing Lender, the Agent, the Lenders, the beneficiary of the Letter of
Credit drawn upon or any other Person, including without limitation any
defense based on any failure of the Borrower or any other Credit Party to
receive consideration or the legality, validity, regularity or
unenforceability of the Letter of Credit.  The Issuing Lender will promptly
notify the other Lenders of the amount of any unreimbursed drawing and each
Lender shall promptly pay to the Agent for the account of the Issuing Lender
in Dollars and in immediately available funds, the amount of such Lender's
pro rata share of such unreimbursed drawing.  Such payment shall be made on
the day such notice is received by such Lender from the Issuing Lender if
such notice is received at or before 1:00 P.M. Central time otherwise such
payment shall be made at or before 12:00 Noon Central time on the Business
Day next succeeding the day such notice is received.  If such Lender does not
pay such amount to the Issuing Lender in full upon such request, such Lender
shall, on demand, pay to the Agent for the account of the Issuing Lender
interest on the unpaid amount during the period from the date of such drawing
until such Lender pays such amount to the Issuing Lender in full at a rate
per annum equal to the Base Rate.  Each Lender's obligation to make such
payment to the Issuing Lender, and the right of the Issuing Lender to receive
the same, shall be absolute and unconditional, shall not be affected by any
circumstance whatsoever and without regard to the termination of this Credit
Agreement or the Commitments hereunder, the existence of a Default or Event
of Default or the acceleration of the obligations of the Borrower hereunder
and shall be made without any offset, abatement, withholding or reduction
whatsoever.  Simultaneously with the making of each such payment by a Lender
to the Issuing Lender, such Lender shall, automatically and without any
further action on the part of the Issuing Lender or such Lender, acquire a
Participation Interest in an amount equal to such payment (excluding the
portion of such payment constituting interest owing to the Issuing Lender) in
the related unreimbursed drawing portion of the LOC Obligation and in the
interest thereon and in the related LOC Documents, and shall have a claim
against the Borrower with respect thereto.

      (e)   Repayment with Revolving Loans.  On any day on which the Borrower
            ------------------------------
shall have requested, or been deemed to have requested, a Revolving Loan
advance to reimburse a drawing under a Letter of Credit, the Agent shall give
notice to the Lenders that a Revolving Loan has been requested or deemed
requested by the Borrower to be made in connection with a drawing under a
Letter of Credit, in which case a Revolving Loan advance comprised of Base
Rate Loans (or Eurodollar Loans to the extent the Borrower has complied with
the procedures of Section 2.1(b)(i) with respect thereto) shall be
immediately made to the Borrower by all Lenders (notwithstanding any
termination of the Commitments pursuant to Section 9.2) pro rata based on the
                                                        --- ----
respective Revolving Commitment Percentages of the Lenders (determined before
giving effect to any termination of the Commitments pursuant to Section 9.2)
and the proceeds thereof shall be paid directly to the Issuing Lender for
application to the respective LOC Obligations.  Each such Lender hereby
irrevocably agrees to make its pro rata share of each such Revolving Loan
immediately upon any such request or deemed request in the amount, in the
manner and on the date specified in the preceding sentence notwithstanding
                                                           ---------------
(i) the amount of such borrowing may not comply with


                                    21
<PAGE> 28

the minimum amount for advances of Revolving Loans otherwise required
hereunder, (ii) whether any conditions specified in Section 5.2 are then
satisfied, (iii) whether a Default or an Event of Default then exists, (iv)
failure for any such request or deemed request for Revolving Loan to be made
by the time otherwise required hereunder, (v) whether the date of such
borrowing is a date on which Revolving Loans are otherwise permitted to be
made hereunder or (vi) any termination of the Commitments relating thereto
immediately prior to or contemporaneously with such borrowing.  In the event
that any Revolving Loan cannot for any reason be made on the date otherwise
required above (including, without limitation, as a result of the
commencement of a proceeding under the Bankruptcy Code with respect to a
Borrower or any Credit Party), then each such Lender hereby agrees that it
shall forthwith purchase (as of the date such borrowing would otherwise have
occurred, but adjusted for any payments received from the Borrower on or
after such date and prior to such purchase) from the Issuing Lender such
Participation Interests in the outstanding LOC Obligations as shall be
necessary to cause each such Lender to share in such LOC Obligations ratably
(based upon the respective Revolving Commitment Percentages of the Lenders
(determined before giving effect to any termination of the Commitments
pursuant to Section 9.2)), provided that at the time any purchase of
                           --------
Participation Interests pursuant to this sentence is actually made, the
purchasing Lender shall be required to pay to the Issuing Lender, to the
extent not paid to the Issuer by the Borrower in accordance with the terms of
subsection (d) above, interest on the principal amount of Participation
Interests purchased for each day from and including the day upon which such
borrowing would otherwise have occurred to but excluding the date of payment
for such Participation Interests, at the rate equal to the Base Rate.

      (f)   Designation of Consolidated Parties as Account Parties.
            ------------------------------------------------------
Notwithstanding anything to the contrary set forth in this Credit Agreement,
including without limitation Section 2.2(a), a Letter of Credit issued
hereunder may contain a statement to the effect that such Letter of Credit is
issued for the account of one Consolidated Party, provided that
notwithstanding such statement, all of the Credit Parties shall be the actual
account party for all purposes of this Credit Agreement for such Letter of
Credit and such statement shall not affect the Credit Parties' reimbursement
obligations hereunder with respect to such Letter of Credit.

      (g)   Renewal, Extension.  The renewal or extension of any Letter of
            ------------------
Credit shall, for purposes hereof, be treated in all respects the same as the
issuance of a new Letter of Credit hereunder.

      (h)   Uniform Customs and Practices.  The Issuing Lender may have the
            -----------------------------
Letters of Credit be subject to The Uniform Customs and Practice for
Documentary Credits, as published as of the date of issue by the
International Chamber of Commerce (the "UCP"), in which case the UCP may be
                                        ---
incorporated therein and deemed in all respects to be a part thereof.

      (i)   Indemnification; Nature of Issuing Lender's Duties.
            --------------------------------------------------

            (i)    In addition to its other obligations under this Section
      2.2, Borrower hereby agrees to pay, and protect, indemnify and save
      each Lender harmless from and against, any and all claims, demands,
      liabilities, damages, losses, costs, charges and expenses (including
      reasonable attorneys' fees) that such Lender may incur or be subject to
      as a consequence, direct or indirect, of (A) the issuance of any Letter
      of Credit or (B) the failure of such Lender to honor a drawing under a
      Letter of Credit as a result of any act or omission, whether rightful
      or wrongful, of any present or future de jure or de facto government or
      Governmental Authority (all such acts or omissions, herein called
      "Government Acts").

            (ii)   As between Borrower and the Lenders (including the Issuing
      Lender), Borrower shall assume all risks of the acts, omissions or
      misuse of any Letter of Credit by the beneficiary thereof.  No Lender
      (including the Issuing Lender) shall be responsible:  (A) for the form,
      validity, sufficiency, accuracy, genuineness or legal effect of any
      document submitted by any party in connection with the application for
      and issuance of any Letter of Credit, even if it should in fact prove
      to be in any or all respects invalid, insufficient, inaccurate,
      fraudulent or forged; (B) for the validity or sufficiency of any
      instrument transferring or assigning or purporting to transfer or
      assign any Letter of Credit or the rights or benefits thereunder or
      proceeds thereof, in whole or in


                                    22
<PAGE> 29

      part, that may prove to be invalid or ineffective for any reason; (C)
      for errors, omissions, interruptions or delays in transmission or
      delivery of any messages, by mail, cable, telegraph, telex or
      otherwise, whether or not they be in cipher; (D) for any loss or delay
      in the transmission or otherwise of any document required in order to
      make a drawing under a Letter of Credit or of the proceeds thereof; and
      (E) for any consequences arising from causes beyond the control of such
      Lender, including, without limitation, any Government Acts.  None of
      the above shall affect, impair, or prevent the vesting of the Issuing
      Lender's rights or powers hereunder.

            (iii)  In furtherance and extension and not in limitation of the
      specific provisions hereinabove set forth, any action taken or omitted
      by any Lender (including the Issuing Lender), under or in connection
      with any Letter of Credit or the related certificates, if taken or
      omitted in good faith, shall not put such Lender under any resulting
      liability to Borrower or any other Credit Party.  It is the intention
      of the parties that this Credit Agreement shall be construed and
      applied to protect and indemnify each Lender (including the Issuing
      Lender) against any and all risks involved in the issuance of the
      Letters of Credit, all of which risks are hereby assumed by the
      Borrower (on behalf of itself and each of the other Credit Parties),
      including, without limitation, any and all Government Acts.  No Lender
      (including the Issuing Lender) shall, in any way, be liable for any
      failure by such Lender or anyone else to pay any drawing under any
      Letter of Credit as a result of any Government Acts or any other cause
      beyond the control of such Lender.

            (iv)   Nothing in this subsection (i) is intended to limit the
      reimbursement obligations of the Borrower contained in subsection (d)
      above.  The obligations of the Borrower under this subsection (ii)
      shall survive the termination of this Credit Agreement.  No act or
      omissions of any current or prior beneficiary of a Letter of Credit
      shall in any way affect or impair the rights of the Lenders (including
      the Issuing Lender) to enforce any right, power or benefit under this
      Credit Agreement.

            (v)    Notwithstanding anything to the contrary contained in this
      subsection (i), Borrower shall have no obligation to indemnify any
      Lender (including the Issuing Lender) in respect of any liability
      incurred by such Lender (A) arising solely out of the gross negligence
      or willful misconduct of such Lender, as determined by a court of
      competent jurisdiction, or (B) caused by such Lender's failure to pay
      under any Letter of Credit after presentation to it of a request
      strictly complying with the terms and conditions of such Letter of
      Credit, as determined by a court of competent jurisdiction, unless such
      payment is prohibited by any law, regulation, court order or decree.

      (j)   Responsibility of Issuing Lender. It is expressly understood and
            --------------------------------
agreed that the obligations of the Issuing Lender hereunder to the Lenders
are only those expressly set forth in this Credit Agreement and that the
Issuing Lender shall be entitled to assume that the conditions precedent set
forth in Section 5.2 have been satisfied unless it shall have acquired actual
knowledge that any such condition precedent has not been satisfied; provided,
                                                                    --------
however, that nothing set forth in this Section 2.2 shall be deemed to
- -------
prejudice the right of any Lender to recover from the Issuing Lender any
amounts made available by such Lender to the Issuing Lender pursuant to this
Section 2.2 in the event that it is determined by a court of competent
jurisdiction that the payment with respect to a Letter of Credit constituted
gross negligence or willful misconduct on the part of the Issuing Lender.

      (k)   Conflict with LOC Documents.  In the event of any conflict
            ---------------------------
between this Credit Agreement and any LOC Document (including any letter of
credit application), this Credit Agreement shall control.

more than five (5) Eurodollar Loans shall be outstanding hereunder at any

shall be considered as separate Eurodollar Loans, even if they begin on the

Periods to constitute a new Eurodollar Loan with a single Interest Period.

            (ii)   Eurodollar Loans. During such periods as the Tranche B
                   ----------------
      Term Loan shall be comprised in whole or in part of Eurodollar Loans,
      such Eurodollar Loans shall bear interest at a per annum rate equal to
      the Adjusted Eurodollar Rate.

Interest on the Tranche B Term Loan shall be payable in arrears on each
applicable Interest Payment Date (or at such other times as may be specified
herein).

      (f)   Tranche B Term Notes.  The portion of the Tranche B Term Loan
made by each Lender shall be evidenced by a duly executed promissory note of
the Borrower to such Lender in an original principal amount equal to such
Lender's Tranche B Term Loan Commitment Percentage of the Tranche B Term Loan
and substantially in the form of Exhibit 2.4(f).
                                 --------------

2.5   Consolidation of Tranche A Term Notes and Tranche B Term Notes.
      --------------------------------------------------------------

      Upon and after the funding of the Tranche B Term Loan, and upon the
request of Borrower or Agent, the Tranche A Term Loan and Tranche B Term Loan
shall be consolidated into one term loan indebtedness ("Term Loan").  Upon
such a consolidation, the Tranche A and Tranche B Term Loan Notes shall be
cancelled and new Term Loan Notes issued to each Lender to reflect the then
outstanding balances of consolidated principal and each Lender's consolidated
Term Loan Commitment.  The form of the new Term Loan Note shall be identical
to the Tranche A Term Loan Note and Tranche B Term Loan Note.  Upon and after
such a consolidation, all references to the Tranche A Term Loan and Note and
the Tranche B Term Loan and Note shall mean the Term Loan and the Term Loan
Note, respectively.  The amortization schedule for the consolidated Term Loan
shall be the sum of the payments shown on Sections 2.3(d) and 2.4(d).

                OTHER PROVISIONS RELATING TO CREDIT FACILITIES
                ----------------------------------------------

      3.1   Default Rate.
            ------------

      Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on
the Loans and any other amounts owing hereunder or under the other Credit
Documents shall bear interest, payable on demand, at a per annum rate 2%
greater than the rate which would otherwise be applicable (or if no rate is
applicable, whether in respect of interest, fees or other amounts, then the
Adjusted Base Rate plus 2%).

      3.2   Extension and Conversion.
            ------------------------

      Subject to the terms of Section 5.2, the Borrower shall have the
option, on any Business Day, to extend existing Loans into a subsequent
permissible Interest Period or to convert Loans into Loans of another
interest rate type; provided, however, that (i) except as provided in Section
                    --------  -------
3.8, Eurodollar Loans may be converted into Base Rate Loans only on the last
day of the Interest Period applicable thereto, (ii) Eurodollar Loans may be
extended, and Base Rate Loans may be converted into Eurodollar Loans, only if
no Default or Event of Default is in existence on the date of extension or
conversion, (iii) Loans extended as, or converted into, Eurodollar Loans
shall be subject to the terms of the definition of "Interest Period" set
                                                    ---------------
forth in Section 1.1 and shall be in such minimum amounts as provided in,
with respect to Revolving Loans, Section 2.1(b)(ii), with respect to the
Tranche A Term Loan, Section 2.3(c), or, with respect to the Tranche B Term
Loan, Section 2.4(c), (iv) no more than fifteen (15) Eurodollar Loans (and,
upon and after a consolidation of Tranche A Term Loan and Tranche B Term Loan
as provided in Section 2.5, no more than ten (10) Eurodollar Loans) shall be
outstanding hereunder at any time (it being understood that, for purposes
hereof, Eurodollar Loans with different Interest Periods shall be considered
as separate Eurodollar Loans, even if they begin on the same date, although
borrowings, extensions and conversions may, in accordance with the provisions
hereof, be combined at the end of existing Interest Periods to constitute a
new Eurodollar Loan with a single Interest Period) and (v) any request for
extension or conversion of a Eurodollar Loan which shall fail to specify an
Interest Period shall be deemed to be a request for an Interest Period of one
month.  Each such extension or conversion shall be effected by the Borrower
by giving a Notice of Extension/Conversion (or telephonic notice promptly
confirmed in writing) to the office of the Agent specified in specified in
Schedule 2.1(a), or at such other office as the Agent may designate in
- ---------------
writing, prior to 1:00 P.M. Central time on the Business Day of, in the case
of the conversion of a Eurodollar Loan into a Base Rate Loan, and on the
third Business Day prior to, in the case of the extension of a Eurodollar
Loan as, or conversion of a Base Rate Loan into, a Eurodollar Loan, the date
of the proposed extension or conversion, specifying the date of the proposed
extension or conversion, the Loans to be so extended or converted, the types
of Loans into which such Loans are to be converted and, if appropriate, the
applicable Interest Periods with respect thereto.  Each request for extension
or conversion shall be irrevocable and shall constitute a representation and
warranty by the Borrower of the matters specified in subsections (b), (c),
(d), (e) and (f) of Section 5.2.  In the event the Borrower fails to request
extension or conversion of any Eurodollar Loan in accordance with this
Section, or any such conversion or extension is not permitted or required by
this Section, then such Eurodollar Loan shall be automatically converted into
a Base Rate Loan at the end of the Interest Period applicable thereto.  The
Agent shall give each Lender notice as promptly as practicable of any such
proposed extension or conversion affecting any Loan.

      3.3   Prepayments.
            -----------

            (a)    Voluntary Prepayments.  The Borrower shall have the right
                   ---------------------
      to prepay Loans in whole or in part from time to time, but otherwise
      without premium or penalty; provided, however, that each partial
                                  --------  -------
      prepayment of Loans shall be in a minimum principal amount of $25,000
      and integral multiples of $25,000.  Subject to the foregoing terms,
      amounts prepaid under this Section 3.3(a) shall be applied as the
      Borrower may elect; provided that if the Borrower fails to specify a
                          --------
      voluntary prepayment then such prepayment shall be applied first to
      Revolving Loans and then ratably to the Tranche A Term Loan and the
      Tranche B Term Loan (in each case ratably to the remaining Principal
      Amortization Payments thereof in the inverse order of maturity), in
      each case first to Base Rate Loans and then to Eurodollar Loans in
      direct order of Interest Period maturities.  Any prepayments of the
      Tranche A Term Loan and the Tranche B Term Loan shall be


                                    27
<PAGE> 34

      to Section 3.12.

            (b)    Mandatory Prepayments.
                   ---------------------

                   (i)    Revolving Committed Amount.  If at any time, the
                          --------------------------
            sum of the aggregate principal amount of outstanding Revolving
            Loans plus LOC Obligations outstanding shall exceed the lesser of
                  ----
            (A) the Revolving Committed Amount or (B) the Borrowing Base, the
            Borrower immediately shall prepay the Revolving Loans in an
            amount sufficient to eliminate such excess.

                   (ii)   Asset Dispositions.  Immediately upon the
                          ------------------
            occurrence of any Asset Disposition Prepayment Event, the
            Borrower shall prepay the Loans in an aggregate amount equal to
            the Net Cash Proceeds of the related Asset Disposition not
            applied (or caused to be applied) by the Consolidated Parties
            during the related Application Period to the purchase,
            acquisition or construction of Eligible Assets as contemplated by
            the terms of Section 8.5 (such prepayment to be applied as set
            forth in clause (v) below).

                   (iii)  Debt Issuances.  Immediately upon receipt by any
                          --------------
            Consolidated Party of proceeds from any Debt Issuance, the
            Borrower shall prepay the Loans in an aggregate amount equal to
            100% of the Net Cash Proceeds of such Debt Issuance to the
            Lenders (such prepayment to be applied as set forth in clause (v)
            below).

                   (iv)   Issuances of Equity.  Immediately upon receipt by a
                          -------------------
            Consolidated Party of proceeds from any Equity Issuance, the
            Borrower shall prepay the Loans in an aggregate amount equal to
            100% of the Net Cash Proceeds of such Equity Issuance to the
            Lenders (such prepayment to be applied as set forth in clause (v)
            below).

                   (v)    Application of Mandatory Prepayments.  All amounts
                          ------------------------------------
            required to be paid pursuant to this Section 3.3(b) shall be
            applied as follows: (A) with respect to all amounts prepaid
            pursuant to Section 3.3(b)(i), to Revolving Loans (B) with
            respect to all amounts prepaid pursuant to Section 3.3(b)(ii),
            (iii) or (iv), pro rata to (1) the Tranche A Term Loan and the
            Tranche B Term Loan (ratably to the remaining Principal
            Amortization Payments thereof in the inverse order of maturity),
            and then (2) Revolving Loans.  Within the parameters of the
            applications set forth above, prepayments shall be applied first
            to Base Rate Loans and then to Eurodollar Loans in direct order
            of Interest Period maturities.  All prepayments under this
            Section 3.3(b) shall, with respect only to Eurodollar Loans, be
            subject to Section 3.12.  With respect to amounts prepaid
            pursuant to Section 3.3(b) (ii) (iii) and (iv), the proceeds of
            the prepayment may, in lieu of the immediate application above
            provided in this sub-Section, be placed in escrow with the
            respective Lender if immediate application would cause Borrower
            to incur payment obligations under Section 3.12.  If such an
            escrow is created, the monies held in escrow shall be applied as
            provided above immediately upon the date when such application
            would not create any payment obligations of Borrower under
            Section 3.12.  The creation of such an escrow shall be evidenced
            by a letter escrow agreement containing terms satisfactory to the
            respective Lender and Agent.

      3.4   Termination and Reduction of Revolving Committed Amount.
            -------------------------------------------------------

      in integral multiples of $500,000 in excess thereof (or, if less, the
      full remaining amount of the then applicable Revolving Committed
      Amount)) upon five Business Days' prior written notice to the Agent;
      provided, however, no such termination or reduction shall be made which
      --------  -------
      would cause the aggregate principal amount of outstanding Revolving
      Loans plus LOC Obligations outstanding to exceed the lesser of (A) the
            ----
      Revolving Committed Amount or (B) the Borrowing Base, unless,
      concurrently with such termination or reduction, the Revolving Loans
      are repaid to the extent necessary to eliminate such excess.  The Agent
      shall promptly


                                    28
<PAGE> 35

      notify each affected Lender of receipt by the Agent of any notice from
      the Borrower pursuant to this Section 3.4(a).

      quarter or portion thereof for which the Unused Fee is payable
      hereunder being herein referred to as an "Unused Fee Calculation
                                                ----------------------
      Period"), beginning with the first of such dates to occur after the
      ------
      Closing Date.

            (b)    Letter of Credit Fees.
                   ---------------------

            hereunder, the Borrower promises to pay to the Agent for the
            account of each Lender a fee (the "Standby Letter of Credit Fee")
                                               ----------------------------
            on such Lender's Revolving Commitment Percentage of the average
            daily maximum amount available to be drawn under each such
            standby Letter of Credit computed at a per annum rate for each
            day from the date of issuance to the date of expiration equal to
            the greater of (a) one percent (1%) of the amount of the Letter

            Revolving Commitment Percentage of the amount of each drawing
            under any such trade Letter of Credit.  The Trade Letter of
            Credit Fee will be payable on each date of drawing under a trade
            Letter of Credit.

                   (iii)  Issuing Lender Fees.  In addition to the Standby

            Letter of Credit Fee payable pursuant to clause (i) above and the
            Trade Letter of Credit Fee payable pursuant to clause (ii) above,
            the Borrower promises to pay to the Issuing Lender for its own
            account without sharing by the other Lenders the letter of credit
            fronting and negotiation fees agreed to by the Borrower and the
            Issuing Lender from time to time and the customary charges from
            time to time of the Issuing Lender with respect to the issuance,
            amendment, transfer, administration, cancellation and conversion
            of, and drawings under, such Letters of Credit (collectively, the

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

      3.6   Capital Adequacy.
            ----------------

      If any Lender has determined, after the date hereof, that the change
in, or any change by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof in the
interpretation or administration of, any law, rule or regulation regarding
capital adequacy which are applicable to all


                                    29
<PAGE> 36

insured depository institutions, or compliance by such Lender with any
request or directive regarding capital adequacy resulting from such change,
has the effect of reducing the rate of return on such Lender's capital or
assets as a consequence of its commitments or obligations hereunder to a
level below that which such Lender could have achieved but for such change or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy), then, upon notice from such Lender to the Borrower,
accompanied by independent verification of such change, the Borrower shall be
obligated to pay to such Lender, within 20 days of demand, such additional
amount or amounts as will compensate such Lender for such reduction.  Each
determination by any such Lender of amounts owing under this Section shall,
absent manifest error, be conclusive and binding on the parties hereto.

      3.7   Limitation on Eurodollar Loans.
            ------------------------------

      If on or prior to the first day of any Interest Period for any
Eurodollar Loan:

            (a)    the Agent determines (which determination shall be
      conclusive) that by reason of circumstances affecting the relevant
      market, adequate and reasonable means do not exist for ascertaining the
      Eurodollar Rate for such Interest Period; or

            (b)    the Required Lenders determine (which determination shall
      be conclusive) and notify the Agent that the Eurodollar Rate will not
      adequately and fairly reflect the cost to the Lenders of funding
      Eurodollar Loans for such Interest Period;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans, Continue Eurodollar Loans, or to Convert
Base Rate Loans into Eurodollar Loans and the Borrower shall, on the last
day(s) of the then current Interest Period(s) for the outstanding Eurodollar
Loans, either prepay such Eurodollar Loans or Convert such Eurodollar Loans
into Base Rate Loans in accordance with the terms of this Credit Agreement.

      3.8   Illegality.
            ----------

      Notwithstanding any other provision of this Credit Agreement, in the
event that it becomes unlawful for any Lender to make, maintain, or fund
Eurodollar Loans hereunder, then such Lender shall promptly notify the
Borrower thereof and such Lender's obligation to make or Continue Eurodollar
Loans and to Convert Base Rate Loans into Eurodollar Loans shall be suspended
until such time as such Lender may again make, maintain, and fund Eurodollar
Loans (in which case the provisions of Section 3.10 shall be applicable).

      3.9   Requirements of Law - Eurodollar Loans.
            --------------------------------------

            (a)    If, after the date hereof, the change in any applicable
      law, rule, or regulation, 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 any Lender with any request or directive
      (whether or not having the force of law) of any such Governmental
      Authority, central bank, or comparable agency:

                   (i)    shall subject such Lender to any tax, duty, or
            other charge with respect to any Eurodollar Loans, its Notes, or
            its obligation to make Eurodollar Loans, or change the basis of
            taxation of any amounts payable to such Lender under this Credit
            Agreement or its Notes in respect of any Eurodollar Loans (other
            than taxes imposed on the overall net income of such Lender by
            the jurisdiction in which such Lender has its principal office;

                   (ii)   shall impose, modify, or deem applicable any
            reserve, special deposit, assessment, or similar requirement
            (other than the Eurodollar Reserve Requirement utilized in the
            determination of the Adjusted Eurodollar Rate) relating to any
            extensions of credit or other assets of, or any deposits with or
            other liabilities or commitments of, such Lender, including the
            Commitment of such Lender hereunder; or


                                    30
<PAGE> 37

                   (iii)  shall impose on such Lender or on the United States
            market for certificates of deposit or the London interbank market
            any other condition affecting this Credit Agreement or its Notes
            or any of such extensions of credit or liabilities or
            commitments;

and the result of any of the foregoing is to increase the cost to such Lender
of making, Converting into, Continuing, or maintaining any Eurodollar Loans
or to reduce any sum received or receivable by such Lender under this Credit
Agreement or its Notes with respect to any Eurodollar Loans, then the
Borrower shall pay to such Lender within twenty (20) days after demand such
amount or amounts as will compensate such Lender for such increased cost or
reduction.  If any Lender requests compensation by the Borrower under this
Section 3.9, the Borrower may, by notice to such Lender (with a copy to the
Agent), suspend the obligation of such Lender to make or Continue Eurodollar
Loans, or to Convert Base Rate Loans into Eurodollar Loans, until the event
or condition giving rise to such request ceases to be in effect (in which
case the provisions of Section 3.10 shall be applicable); provided that such
suspension shall not affect the right of such Lender to receive the
compensation so requested.

            (b)    Each Lender shall promptly notify the Borrower and the
      Agent of any event of which it has knowledge, occurring after the date
      hereof, which will entitle such Lender to compensation pursuant to this
      Section 3.9 and will designate a different lending office if such
      designation will avoid the need for, or reduce the amount of, such
      compensation and will not, in the judgment of such Lender, be otherwise
      disadvantageous to it.  Any Lender claiming compensation under this
      Section 3.9 shall furnish to the Borrower and the Agent a statement
      setting forth the additional amount or amounts to be paid to it
      hereunder which shall be conclusive in the absence of manifest error.
      In determining such amount, such Lender may use any reasonable
      averaging and attribution methods.

      3.10  Treatment of Affected Loans.
            ---------------------------

      If the obligation of any Lender to make any Eurodollar Loan or to
Continue, or to Convert Base Rate Loans into, Eurodollar Loans shall be
suspended pursuant to Section 3.8 or 3.9 hereof, such Lender's Eurodollar
Loans shall be automatically Converted into Base Rate Loans on the last
day(s) of the then current Interest Period(s) for such Eurodollar Loans (or,
in the case of a Conversion required by Section 3.8 hereof, on such earlier
date as such Lender may specify to the Borrower with a copy to the Agent)
and, unless and until such Lender gives notice as provided below that the
circumstances specified in Section 3.8 or 3.9 hereof that gave rise to such
Conversion no longer exist:

            (a)     to the extent that such Lender's Eurodollar Loans have
      been so Converted, all payments and prepayments of principal that would
      otherwise be applied to such Lender's Eurodollar Loans shall be applied
      instead to its Base Rate Loans; and

            (b)    all Loans that would otherwise be made or Continued by
      such Lender as Eurodollar Loans shall be made or Continued instead as
      Base Rate Loans, and all Base Rate Loans of such Lender that would
      otherwise be Converted into Eurodollar Loans shall remain as Base Rate
      Loans.

If such Lender gives notice to the Borrower (with a copy to the Agent) that
the circumstances specified in Section 3.8 or 3.9 hereof that gave rise to
the Conversion of such Lender's Eurodollar Loans pursuant to this Section
3.10 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans made by other
Lenders are outstanding, such Lender's Base Rate Loans shall be automatically
Converted, on the first day(s) of the next succeeding Interest Period(s) for
such outstanding Eurodollar Loans, to the extent necessary so that, after
giving effect thereto, all Loans held by the Lenders holding Eurodollar Loans
and by such Lender are held pro rata (as to principal amounts, interest rate
basis, and Interest Periods) in accordance with their respective Commitments.

      3.11  Taxes.
            -----

            (a)    Any and all payments by the Borrower to or for the account
      of any Lender or the Agent hereunder or under any other Credit Document
      shall be made free and clear of and without deduction for any and all
      present or future taxes, duties, levies, imposts, deductions, charges
      or withholdings, and all liabilities with respect thereto, excluding,
                                                                 ---------
      in the case of each Lender and the Agent, taxes imposed on its


                                    31
<PAGE> 38

      income, and franchise taxes imposed on it, by the jurisdiction under
      the laws of which such Lender or the Agent (as the case may be) is
      organized or any political subdivision thereof (all such non-excluded
      taxes, duties, levies, imposts, deductions, charges, withholdings, and
      liabilities being hereinafter referred to as "Taxes").  If the Borrower
      shall be required by law to deduct any Taxes from or in respect of any
      sum payable under this Credit Agreement or any other Credit Document to
      any Lender or the Agent, (i) the sum payable shall be increased as
      necessary so that after making all required deductions (including
      deductions applicable to additional sums payable under this Section
      3.11) such Lender or the Agent receives an amount equal to the sum it
      would have received had no such deductions been made, (ii) the Borrower
      shall make such deductions, (iii) the Borrower shall pay the full
      amount deducted to the relevant taxation authority or other authority
      in accordance with applicable law, and (iv) the Borrower shall furnish
      to the Agent, at its address referred to in Section 11.1, the original
      or a certified copy of a receipt evidencing payment thereof.

            (b)    In addition, the Borrower agrees to pay any and all
      present or future stamp or documentary taxes and any other excise or
      property taxes or charges or similar levies which arise from any
      payment made under this Credit Agreement or any other Credit Document
      or from the execution or delivery of, or otherwise with respect to,
      this Credit Agreement or any other Credit Document (hereinafter
      referred to as "Other Taxes").
                      -----------

            (c)    The Borrower agrees to indemnify each Lender and the Agent
      for the full amount of Taxes and Other Taxes (including, without
      limitation, any Taxes or Other Taxes imposed or asserted by any
      jurisdiction on amounts payable under this Section 3.11) paid by such
      Lender or the Agent (as the case may be) and any liability (including
      penalties, interest, and expenses) arising therefrom or with respect
      thereto.

            (d)    If the Borrower is required to pay additional amounts to
      or for the account of any Lender pursuant to this Section 3.11, then
      such Lender will agree to use reasonable efforts to change the
      jurisdiction of its lending office so as to eliminate or reduce any
      such additional payment which may thereafter accrue if such change, in
      the judgment of such Lender, is not otherwise disadvantageous to such
      Lender.

            (e)    Within thirty (30) days after the date of any payment of
      Taxes, the Borrower shall furnish to the Agent the original or a
      certified copy of a receipt evidencing such payment.

            (f)    Without prejudice to the survival of any other agreement
      of the Borrower hereunder, the agreements and obligations of the
      Borrower contained in this Section 3.11 shall survive the repayment of
      the Loans, LOC Obligations and other obligations under the Credit
      Documents and the termination of the Commitments hereunder.

      3.12  Compensation Concerning Eurodollar Loans.
            ----------------------------------------

      Upon the request of any Lender making or holding a Eurodollar Loan, the
Borrower shall pay to such Lender such amount or amounts as shall be
sufficient (in the reasonable opinion of such Lender) to compensate it for
any loss, cost, or expense (including loss of anticipated profits) incurred
by it as a result of:

            (a)    any payment, prepayment, or Conversion of a Eurodollar
      Loan for any reason (including, without limitation, the acceleration of
      the Loans pursuant to Section 9.2) on a date other than the last day of
      the Interest Period for such Loan; or

            (b)    any failure by the Borrower for any reason (including,
      without limitation, the failure of any condition precedent specified in
      Section 5 to be satisfied) to borrow, Convert, Continue, or prepay a
      Eurodollar Loan on the date for such borrowing, Conversion,
      Continuation, or prepayment specified in the relevant notice of
      borrowing, prepayment, Continuation, or Conversion under this Credit
      Agreement.

With respect to Eurodollar Loans, such indemnification may include an amount
equal to the excess, if any, of (a) the amount of interest which would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of the applicable Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period
that


                                    32
<PAGE> 39

would have commenced on the date of such failure) in each case at the
applicable rate of interest for such Eurodollar Loans provided for herein
(excluding, however, the Applicable Percentage included therein, if any) over
(b) the amount of interest (as reasonably determined by such Lender) which
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank
Eurodollar market.  The covenants of the Borrower set forth in this Section
3.12 shall survive the repayment of the Loans, LOC Obligations and other
obligations under the Credit Documents and the termination of the Commitments
hereunder.

      3.13  Pro Rata Treatment.
            ------------------

      Except to the extent otherwise provided herein:

            (a)    Loans.  Each Loan, each payment or (subject to the terms
                   -----
      of Section 3.3) prepayment of principal of any Loan or reimbursement
      obligations arising from drawings under Letters of Credit, each payment
      of interest on the Loans or reimbursement obligations arising from
      drawings under Letters of Credit, each payment of Unused Fees, each
      payment of the Standby Letter of Credit Fee, each payment of the Trade
      Letter of Credit Fee, each reduction of the Revolving Committed Amount
      and each conversion or extension of any Loan, shall be allocated pro
      rata among the Lenders in accordance with the respective principal
      amounts of their outstanding Loans and Participation Interests.

            Advances.  No Lender shall be responsible for the failure or
            --------
      delay by any other Lender in its obligation to make its ratable share
      of a borrowing hereunder; provided, however, that the failure of any
                                --------  -------
      Lender to fulfill its obligations hereunder shall not relieve any other
      Lender of its obligations hereunder.  Unless the Agent shall have been
      notified by any Lender prior to the date of any requested borrowing
      that such Lender does not intend to make available to the Agent its
      ratable share of such borrowing to be made on such date, the Agent may
      assume that such Lender has made such amount available to the Agent on
      the date of such borrowing, and the Agent in reliance upon such
      assumption, may (in its sole discretion but without any obligation to
      do so) make available to the Borrower a corresponding amount and such
      amount shall be a Loan under this Agreement.  If such corresponding
      amount is not in fact made available to the Agent, the Agent shall be
      able to recover such corresponding amount from such Lender.  The Agent
      shall also be entitled to recover from the Lender interest on such
      corresponding amount in respect of each day from the date such
      corresponding amount was made available by the Agent to the Borrower to
      the date such corresponding amount is recovered by the Agent at a per
      annum rate equal to the Base Rate.

      3.14  Sharing of Payments.
            -------------------

      The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan, LOC Obligations or any other
obligation owing to such Lender under this Credit Agreement through the
exercise of a right of setoff, banker's lien or counterclaim, or pursuant to
a secured claim under Section 506 of Title 11 of the United States Code or
other security or interest arising from, or in lieu of, such secured claim,
received by such Lender under any applicable bankruptcy, insolvency or other
similar law or otherwise, or by any other means, in excess of its pro rata
share of such payment as provided for in this Credit Agreement, such Lender
shall promptly purchase from the other Lenders a Participation Interest in
such Loans, LOC Obligations and other obligations in such amounts, and make
such other adjustments from time to time, as shall be equitable to the end
that all Lenders share such payment in accordance with their respective
ratable shares as provided for in this Credit Agreement.  The Lenders further
agree among themselves that if payment to a Lender obtained by such Lender
through the exercise of a right of setoff, banker's lien, counterclaim or
other event as aforesaid shall be rescinded or must otherwise be restored,
each Lender which shall have shared the benefit of such payment shall, by
repurchase of a Participation Interest theretofore sold, return its share of
that benefit (together with its share of any accrued interest payable with
respect thereto) to each Lender whose payment shall have been rescinded or
otherwise restored.  The Borrower agrees that any Lender so purchasing such a
Participation Interest may, to the fullest extent permitted by law, exercise
all rights of payment, including setoff, banker's lien or counterclaim, with
respect to such Participation Interest as fully as if such Lender were a
holder of such Loan, LOC Obligations or other obligation in the amount of
such Participation Interest.  Except as otherwise expressly provided in this
Credit Agreement, if any Lender or the Agent shall fail to remit to the Agent
or any other Lender an amount payable by such Lender or the Agent to the
Agent or such other Lender pursuant to this Credit Agreement on the date when
such amount is due, such payments shall be made together with interest
thereon for each date from the date such amount is due until the date such


                                    33
<PAGE> 40

amount is paid to the Agent or such other Lender at a rate per annum equal to
the Base Rate.  If under any applicable bankruptcy, insolvency or other
similar law, any Lender receives a secured claim in lieu of a setoff to which
this Section 3.14 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent
with the rights of the Lenders under this Section 3.14 to share in the
benefits of any recovery on such secured claim.

      3.15  Payments, Computations, Etc.
            ---------------------------

            (a)    Except as otherwise specifically provided herein, all
      payments hereunder shall be made to the Agent in dollars in immediately
      available funds, without offset, deduction, counterclaim or withholding
      of any kind, at the Agent's office specified in Schedule 2.1(a) not
                                                      ---------------
      later than 2:00 P.M. Central time on the date when due.  Payments
      received after such time shall be deemed to have been received on the
      next succeeding Business Day.  The Agent may (but shall not be
      obligated to) debit the amount of any such payment which is not made by
      such time to any ordinary deposit account of the Borrower maintained
      with the Agent (with notice to the Borrower).  The Borrower shall, at
      the time it makes any payment under this Credit Agreement, specify to
      the Agent the Loans, LOC Obligations, Fees, interest or other amounts
      payable by the Borrower hereunder to which such payment is to be
      applied (and in the event that it fails so to specify, or if such
      application would be inconsistent with the terms hereof, the Agent
      shall distribute such payment to the Lenders in such manner as the
      Agent may determine to be appropriate in respect of obligations owing
      by the Borrower hereunder, subject to the terms of Section 3.13(a)).
      The Agent will distribute such payments to such Lenders, if any such
      payment is received prior to 1:00 P.M. Central time on a Business Day
      in like funds as received prior to the end of such Business Day and
      otherwise the Agent will distribute such payment to such Lenders on the
      next succeeding Business Day.  Whenever any payment hereunder shall be
      stated to be due on a day which is not a Business Day, the due date
      thereof shall be extended to the next succeeding Business Day (subject
      to accrual of interest and Fees for the period of such extension),
      except that in the case of Eurodollar Loans, if the extension would
      cause the payment to be made in the next following calendar month, then
      such payment shall instead be made on the next preceding Business Day.
      Except as expressly provided otherwise herein, all computations of
      interest and fees shall be made on the basis of actual number of days
      elapsed over a year of 360 days.  Interest shall accrue from and
      include the date of borrowing, but exclude the date of payment.

            (b)    Allocation of Payments After Event of Default.
                   ---------------------------------------------
      Notwithstanding any other provisions of this Credit Agreement to the
      contrary, after the occurrence and during the continuance of an Event
      of Default, all amounts collected or received by the Agent or any
      Lender on account of the Credit Party Obligations or any other amounts
      outstanding under any of the Credit Documents or in respect of the
      Collateral shall be paid over or delivered as follows:

            FIRST, to the payment of all reasonable out-of-pocket costs and
      expenses (including without limitation reasonable attorneys' fees) of
      the Agent in connection with enforcing the rights of the Lenders under
      the Credit Documents and any protective advances made by the Agent with
      respect to the Collateral under or pursuant to the terms of the
      Collateral Documents;

            SECOND, to payment of any fees owed to the Agent;

            THIRD, to the payment of all reasonable out-of-pocket costs and
      expenses (including without limitation, reasonable attorneys' fees) of
      each of the Lenders in connection with enforcing its rights under the
      Credit Documents or otherwise with respect to the Credit Party
      Obligations owing to such Lender;

            FOURTH, to the payment of all of the Credit Party Obligations
      consisting of accrued fees and interest;

            FIFTH, to the payment of the outstanding principal amount of the
      Credit Party Obligations (including the payment or cash
      collateralization of the outstanding LOC Obligations);


                                    34
<PAGE> 41

            SIXTH, to all other Credit Party Obligations and other
      obligations which shall have become due and payable under the Credit
      Documents or otherwise and not repaid pursuant to clauses "FIRST"
      through "FIFTH" above; and

            SEVENTH, to the payment of the surplus, if any, to whoever may be
      lawfully entitled to receive such surplus.

      In carrying out the foregoing, (i) amounts received shall be applied in
      the numerical order provided until exhausted prior to application to
      the next succeeding category; (ii) each of the Lenders shall receive an
      amount equal to its pro rata share (based on the proportion that the
      then outstanding Loans and LOC Obligations held by such Lender bears to
      the aggregate then outstanding Loans and LOC Obligations) of amounts
      available to be applied pursuant to clauses "THIRD", "FOURTH", "FIFTH"
      and "SIXTH" above; and (iii) to the extent that any amounts available
      for distribution pursuant to clause "FIFTH" above are attributable to
      the issued but undrawn amount of outstanding Letters of Credit, such
      amounts shall be held by the Agent in a cash collateral account and
      applied (A) first, to reimburse the Issuing Lender from time to time
      for any drawings under such Letters of Credit and (B) then, following
      the expiration of all Letters of Credit, to all other obligations of
      the types described in clauses "FIFTH" and "SIXTH" above in the manner
      provided in this Section 3.15(b).

      3.16  Evidence of Debt.
            ----------------

            (a)    Each Lender shall maintain an account or accounts
      evidencing each Loan made by such Lender to the Borrower from time to
      time, including the amounts of principal and interest payable and paid
      to such Lender from time to time under this Credit Agreement.  Each
      Lender will make reasonable efforts to maintain the accuracy of its
      account or accounts and to promptly update its account or accounts from
      time to time, as necessary.

            (b)    The Agent shall maintain the Register pursuant to Section
      11.3(c), and a subaccount for each Lender, in which Register and
      subaccounts (taken together) shall be recorded (i) the amount, type and
      Interest Period of each such Loan hereunder, (ii) the amount of any
      principal or interest due and payable or to become due and payable to
      each Lender hereunder and (iii) the amount of any sum received by the
      Agent hereunder from or for the account of the Borrower and each
      Lender's share thereof.  The Agent will make reasonable efforts to
      maintain the accuracy of the subaccounts referred to in the preceding
      sentence and to promptly update such subaccounts from time to time, as
      necessary.

            (c)    The entries made in the accounts, Register and subaccounts
      maintained pursuant to subsection (b) of this Section 3.16 (and, if
      consistent with the entries of the Agent, subsection (a)) shall be
      prima facie evidence of the existence and amounts of the obligations of
      the Borrower therein recorded; provided, however, that the failure of
                                     --------  -------
      any Lender or the Agent to maintain any such account, such Register or
      such subaccount, as applicable, or any error therein, shall not in any
      manner affect the obligation of the Borrower to repay the Loans made by
      such Lender in accordance with the terms hereof.

      the receipt and approval of the executed Purchase Agreement for the
      Acquisition of Acquired Company-B, and a Schedule 5.1(11)-B reflecting
                                               ------------------

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

      The Credit Parties hereby represent to the Agent and each Lender that:

      of Consolidated Parties as of October 31, 1997 and the audited
      consolidated and consolidating statements of earnings and statements of
      cash flows for the years ended October 31, 1997 and October 31, 1996
      and for the 3-month period ended January 31, 1998 have heretofore been
      furnished to each Lender.  Such financial statements (including the
      notes thereto), except for the 3-month financial statements (i) have

      such financial statements) the consolidated financial condition,
      results of operations and cash flows of the Consolidated Parties as of
      such date and for such periods.  The unaudited interim balance sheets
      of the Consolidated Parties as at the end of, and the related unaudited
      interim statements of earnings and of cash flows for, each fiscal month
      and quarterly period ended after October 31, 1997 and prior to the
      Closing Date have heretofore been furnished to each Lender.  Such
      interim financial statements for each such quarterly period, (i) have
      been prepared in accordance with GAAP consistently applied throughout
      the periods covered thereby and (ii) present fairly (on the basis
      disclosed in the footnotes to such financial statements) the
      consolidated and consolidating financial condition, results of
      operations and cash flows of the Consolidated Parties as of such date
      and for such periods.  During the period from October 31, 1997 to and
      including the Closing Date, there has been no sale, transfer or other
      disposition by any Consolidated Party of any material part of the
      business or property of the Consolidated Parties, taken as a whole, and
      except for the Acquisition of Acquired Company A no purchase or other
      acquisition by any of them of any business or property (including any
      capital stock of any other person) material in relation to the
      consolidated financial condition of the Consolidated Parties, taken as
      a whole, in each case, which, is not reflected in the foregoing
      financial statements or in the notes thereto and has not otherwise been
      disclosed in writing to the Lenders on or prior to the Closing Date.

            (b)    The pro forma consolidated balance sheet of the
      Consolidated Parties as of the Closing Date giving effect to the
      Acquisition of Acquired Company-A in accordance with the terms of the
      Purchase Agreement and reflecting estimated purchase price accounting
      adjustments, has heretofore been furnished to each Lender.  Such pro
      forma balance sheet is based upon reasonable assumptions made known to
      the Lenders and upon information not know to be incorrect or misleading
      in any material respect.

constitutes, and each other Credit Document to which any Credit Party is a
party when executed and delivered will constitute, a legal, valid and binding
obligation of such Credit Party enforceable against such party in accordance
with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditors' rights generally and by general equitable
principles (whether enforcement is sought by proceedings in equity or at
law).

      6.5   No Conflicts.
            ------------

      Neither the execution and delivery of the Credit Documents, nor the

incorporation or bylaws or other organizational or governing documents of
such Person, (b) violate, contravene or materially conflict with any
Requirement of Law or any other law, regulation (including, without

      6.12  ERISA.
            -----

      Except as disclosed and described in Schedule 6.12 attached hereto:
                                           -------------

            (a)    During the five-year period prior to the date on which
      this representation is made or deemed made: (i) no ERISA Event has
      occurred, and, to the best knowledge of the Credit Parties, no event or
      condition has occurred or exists as a result of which any ERISA Event
      could reasonably be expected to occur, with respect to any Plan; (ii)
      no "accumulated funding deficiency," as such term is defined in Section
      302 of ERISA and Section 412 of the Code, whether or not waived, has
      occurred with respect to any Plan; (iii) each Single Employer Plan and,
      to the best knowledge of the Credit Parties, each Multiemployer Plan
      has been maintained, operated, and funded in compliance with its own
      terms and in material compliance with the provisions of ERISA, the
      Code, and any other applicable federal or state laws; and (iv) no lien
      in favor of the PBGC or a Plan has arisen or is reasonably likely to
      arise on account of any Plan.

            (b)    The actuarial present value of all "benefit liabilities"
      (as defined in Section 4001(a)(16) of ERISA), whether or not vested,
      under each Single Employer Plan, as of the last annual valuation date
      prior to the date on which this representation is made or deemed made
      (determined, in each case, in


                                    43
<PAGE> 50

      accordance with Financial Accounting Standards Board Statement 87,
      utilizing the actuarial assumptions used in such Plan's most recent
      actuarial valuation report), did not exceed as of such valuation date
      the fair market value of the assets of such Plan.

            (c)    Neither any Consolidated Party nor any ERISA Affiliate has
      incurred, or, to the best knowledge of the Credit Parties, could be
      reasonably expected to incur, any withdrawal liability under ERISA to
      any Multiemployer Plan or Multiple Employer Plan.  Neither any
      Consolidated Party nor any ERISA Affiliate would become subject to any
      withdrawal liability under ERISA if any Consolidated Party or any ERISA
      Affiliate were to withdraw completely from all Multiemployer Plans and
      Multiple Employer Plans as of the valuation date most closely preceding
      the date on which this representation is made or deemed made.  Neither
      any Consolidated Party nor any ERISA Affiliate has received any
      notification that any Multiemployer Plan is in reorganization (within
      the meaning of Section 4241 of ERISA), is insolvent (within the meaning
      of Section 4245 of ERISA), or has been terminated (within the meaning
      of Title IV of ERISA), and no Multiemployer Plan is, to the best
      knowledge of the Credit Parties, reasonably expected to be in
      reorganization, insolvent, or terminated.

            (d)    No prohibited transaction (within the meaning of Section
      406 of ERISA or Section 4975 of the Code) or breach of fiduciary
      responsibility has occurred with respect to a Plan which has subjected
      or may subject any Consolidated Party or any ERISA Affiliate to any
      liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
      Section 4975 of the Code, or under any agreement or other instrument
      pursuant to which any Consolidated Party or any ERISA Affiliate has
      agreed or is required to indemnify any person against any such
      liability.

            (e)    Neither any Consolidated Party nor any ERISA Affiliates
      has any material liability with respect to "expected post-retirement
      benefit obligations" within the meaning of the Financial Accounting
      Standards Board Statement 106.  Each Plan which is a welfare plan (as
      defined in Section 3(1) of ERISA) to which Sections 601-609 of ERISA
      and Section 4980B of the Code apply has been administered in compliance
      in all material respects of such sections.

            (f)    Neither the execution and delivery of this Credit
      Agreement nor the consummation of the financing transactions
      contemplated thereunder will involve any transaction which is subject
      to the prohibitions of Sections 404, 406 or 407 of ERISA or in
      connection with which a tax could be imposed pursuant to Section 4975
      of the Code.  The representation by the Credit Parties in the preceding
      sentence is made in reliance upon and subject to the accuracy of the
      Lenders' representation in Section 11.15 with respect to their source
      of funds and is subject, in the event that the source of the funds used
      by the Lenders in connection with this transaction is an insurance
      company's general asset account, to the application of Prohibited
      Transaction Class Exemption 95-60, 60 Fed. Reg. 35,925 (1995),
      compliance with the regulations issued under Section 401(c)(1)(A) of
      ERISA, or the issuance of any other prohibited transaction exemption or
      similar relief, to the effect that assets in an insurance company's
      general asset account do not constitute assets of an "employee benefit
      plan" within the meaning of Section 3(3) of ERISA of a "plan" within
      the meaning of Section 4975(e)(1) of the Code.

Capital Stock outstanding, the number and percentage of outstanding shares of

any such Person have outstanding any rights to subscribe for or to purchase
or any options for the purchase of, or any agreements providing for the
issuance (contingent or otherwise) of, or any calls, commitments or claims of
any character relating to its Capital Stock.  Schedule 6.13 may be updated
                                              -------------
from time to time by the Borrower by giving written notice thereof to the
Agent.

      Public Utility Holding Company Act of 1935, the Federal Power Act or
      the Investment Company Act of 1940, each as amended.  In addition, no
      Consolidated Party is (i) an "investment company" registered or

            (c)    No director, executive officer or principal shareholder of

      Party is in violation of any applicable statute, regulation or

      municipality, county or any other jurisdiction, or of any agency
      thereof (including without limitation, environmental laws and
      regulations), which violation could have a Material Adverse Effect.

      such financial statements have been prepared in accordance with GAAP
      (except for changes with which such accountants concur) and shall not

            environmental report within seventy-five (75) days after receipt
            of such written request then the Agent may arrange for same, and
            the Consolidated Parties hereby grant to the Agent and their

            Environmental Laws and with the validly issued orders and
            directives of all Governmental Authorities with jurisdiction over

            pursue to conclusion on or before April 1, 1999, the recommended
            actions contained in the environmental analysis and survey dated

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

restriction could have a Material Adverse Effect.

      7.5   Payment of Taxes and Other Indebtedness.
            ---------------------------------------

      Each Credit Party will, and will cause each of its Subsidiaries to, pay

(including claims for labor, materials and supplies) which, if unpaid, might

hereunder, all of its other Indebtedness as it shall become due; provided,
however, that no Consolidated Party shall be required to pay any such tax,
assessment, charge, levy, claim or Indebtedness which is being contested in
good faith by appropriate proceedings and as to which adequate reserves
therefor have been established in accordance with GAAP, unless the failure to
make any such payment (i) could give rise to an immediate right to foreclose
on a Lien securing such amounts or (ii) could have a Material Adverse Effect.

      7.6   Insurance.
            ---------

            (a)    Each Credit Party will, and will cause each of its
      Subsidiaries to, at all times maintain in full force and effect
      insurance (including worker's compensation insurance, liability
      insurance, casualty insurance and business interruption insurance) in
      such amounts, covering such risks and liabilities and with such
      deductibles or self-insurance retentions as are in accordance with
      normal industry practice (or as otherwise required by the Collateral
      Documents). The Agent shall be named as loss payee or mortgagee, as its
      interest may appear, and/or additional insured with respect to any such
      insurance providing coverage in respect of any Collateral, and each
      provider of any such insurance shall agree, by endorsement upon the
      policy or policies issued by it or by independent instruments furnished

      written notice before any such policy or policies shall be altered or
      canceled, and that no act or default of any Consolidated Party or any
      other Person shall affect the rights of the Agent or the Lenders under
      such policy or policies.

            (b)    In case of any material loss, damage to or destruction of
      the Collateral of any Credit Party or any part thereof, such Credit
      Party shall promptly give written notice thereof to the Agent generally

      case of any loss, damage to or

<PAGE> 57

      destruction of the Collateral of any Credit Party or any part thereof,
      such Credit Party, whether or not the insurance proceeds, if any,
      received on account of such damage or destruction shall be sufficient
      for that purpose, at such Credit Party's cost and expense, will
      promptly repair or replace the Collateral of such Credit Party so lost,
      damaged or destroyed; provided, however, that such Credit Party need
                            --------  -------
      not repair or replace the Collateral of such Credit Party so lost,
      damaged or destroyed to the extent the failure to make such repair or
      replacement (i) is desirable to the proper conduct of the business of
      such Credit Party in the ordinary course and otherwise in the best
      interest of such Credit Party; and (ii) would not materially impair the
      rights and benefits of the Agent or the Lenders under the Collateral
      Documents, any other Credit Document or any Hedging Agreement.  In the
      event a Credit Party shall receive any proceeds of such insurance in a
      net amount in excess of $250,000, such Credit Party will immediately
      pay over such excess proceeds to the Agent, for payment on the Credit
      Party Obligations as provided in Section 3.3(b)(v); provided, however,
                                                          --------  -------
      that the Agent agrees to release the insurance proceeds to such Credit
      Party for replacement or restoration of the portion of the Collateral
      of such Credit Party lost, damaged or destroyed if, but only if, (A) no
      Default or Event of Default shall have occurred and be continuing at
      the time of release, (B) written application for such release is
      received by the Agent from such Credit Party within 30 days of receipt
      of such proceeds and (C) the Agent has received evidence reasonably
      satisfactory to it that the Collateral lost, damaged or destroyed has
      been or will be fully replaced or restored to its condition immediately
      prior to the loss, destruction or other event giving rise to the
      payment of such insurance proceeds

      7.7   Maintenance of Property.
            -----------------------

      Each Credit Party will, and will cause each of its Subsidiaries to,

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

to make photocopies or photographs thereof and to write down and record any
information such representative obtains and shall permit the Agent or its
representatives to investigate and verify the accuracy of information
provided to the Lenders and to discuss all such matters with the officers,
employees and representatives of such Person.  The Credit Parties agree that
the Agent, and its representatives, may conduct an annual audit of the
Collateral, at the expense of the Borrower up to but not in excess of $5000
per audit.

      to result in the termination of such Plan for purposes of Title IV of
      ERISA; (iii) an ERISA Event shall occur with respect to a Multiemployer
      Plan or Multiple Employer Plan, which is, in the reasonable opinion of
      the Agent, likely to result in (A) the termination of such Plan for
      purposes of Title IV of ERISA, or (B) any Consolidated Party or any
      ERISA Affiliate incurring any liability in connection with a withdrawal
      from, reorganization of (within the meaning of Section 4241 of ERISA),
      or insolvency or (within the meaning of Section 4245 of ERISA) such
      Plan; or (iv) any prohibited transaction (within the meaning of Section
      406 of ERISA or Section 4975 of the Code) or breach of fiduciary
      responsibility shall occur which may subject any Consolidated Party or
      any ERISA Affiliate to any liability under Sections 406, 409, 502(i),
      or 502(l) of ERISA or Section 4975 of the Code, or under any agreement
      or other instrument pursuant to which any Consolidated Party or any
      ERISA Affiliate has agreed or is required to indemnify any person
      against any such liability; or

            (i)    Ownership.  There shall occur a Change of Control.

      9.2   Acceleration; Remedies.
            ----------------------

      Upon the occurrence of an Event of Default, and at any time thereafter
unless and until such Event of Default has been waived by the requisite
Lenders (pursuant to the voting requirements of Section 11.6) or cured to the
satisfaction of the requisite Lenders (pursuant to the voting procedures in
Section 11.6), the Agent shall, upon the request and direction of the
Required Lenders, by written notice to the Credit Parties take any of the
following actions:

            (a)    Termination of Commitments.  Declare the Commitments
                   --------------------------
      terminated whereupon the Commitments shall be immediately terminated.

            (b)    Acceleration.  Declare the unpaid principal of and any
                   ------------
      accrued interest in respect of all Loans, any reimbursement obligations
      arising from drawings under Letters of Credit and any and all other
      indebtedness or obligations of any and every kind owing by the Borrower
      to the Agent and/or any of the Lenders hereunder to be due whereupon
      the same shall be immediately due and payable without presentment,
      demand, protest or other notice of any kind, all of which are hereby
      waived by the Borrower.

            (c)    Cash Collateral.  Direct the Borrower to pay (and the
                   ---------------
      Borrower agrees that upon receipt of such notice, or upon the
      occurrence of an Event of Default under Section 9.1(e), it will
      immediately pay) to the Agent additional cash, to be held by the Agent,
      for the benefit of the Lenders, in a cash collateral account as
      additional security for the LOC Obligations in respect of subsequent
      drawings under all then outstanding Letters of Credit in an amount
      equal to the maximum aggregate amount which may be drawn under all
      Letters of Credits then outstanding.

            (d)    Enforcement of Rights.  Enforce any and all rights and
                   ---------------------
      interests created and existing under the Credit Documents including,
      without limitation, all rights and remedies existing under the
      Collateral Documents, and all rights of set-off.

      Notwithstanding the foregoing, if an Event of Default specified in
Section 9.1(e) shall occur, then the Commitments shall automatically
terminate and all Loans, all reimbursement obligations arising from drawings
under Letters of Credit, all accrued interest in respect thereof, all accrued
and unpaid Fees and other indebtedness or obligations owing to the Agent
and/or any of the Lenders hereunder automatically shall immediately become
due and payable without the giving of any notice or other action by the Agent
or the Lenders.


                                  SECTION 10
                               AGENCY PROVISIONS
                               -----------------

      10.1  Appointment, Powers and Immunities.
            ----------------------------------

      Each Lender hereby irrevocably appoints and authorizes the Agent to act
as its agent under this Credit Agreement and the other Credit Documents with
such powers and discretion as are specifically delegated to the Agent by the
terms of this Credit Agreement and the other Credit Documents, together with
such other powers as are reasonably incidental thereto.  The Agent (which
term as used in this sentence and in Section 10.5 and the first sentence of
Section 10.6 hereof shall include its Affiliates and its own and its
Affiliates' officers, directors, employees, and agents):  (a) shall not have
any duties or responsibilities except those expressly set forth in this
Credit Agreement and shall not be a trustee or fiduciary for any Lender; (b)
shall not be responsible to the Lenders for any recital, statement,
representation, or warranty (whether written or oral) made in or in
connection with any Credit Document or any certificate or other document
referred to or provided for in, or received by any of them under, any Credit
Document, or for the value, validity, effectiveness, genuineness,
enforceability, or sufficiency of any Credit Document, or any other document
referred to or provided for therein or for any failure by any Credit Party or
any other Person to perform any of its obligations thereunder; (c) shall not
be responsible for or have any duty to ascertain, inquire into, or verify
the performance or observance of any covenants or agreements by any Credit
Party or the satisfaction of any condition or to inspect the property
(including the books and records) of any Credit Party or any of its
Subsidiaries or Affiliates; (d) shall not be required to initiate or conduct
any litigation or collection proceedings under any Credit Document; and (e)
shall not be responsible for any action taken or omitted to be taken by it
under or in connection with any Credit Document, except for its own gross
negligence or willful


                                    58
<PAGE> 65

misconduct.  The Agent may employ agents and attorneys-in-fact and shall not
be responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.

      10.2  Reliance by Agent.
            -----------------

      The Agent shall be entitled to rely upon any certification, notice,
instrument, writing, or other communication (including, without limitation,
any thereof by telephone or telecopy) believed by it to be genuine and
correct and to have been signed, sent or made by or on behalf of the proper
Person or Persons, and upon advice and statements of legal counsel (including
counsel for any Credit Party), independent accountants, and other experts
selected by the Agent.  The Agent may deem and treat the payee of any Note as
the holder thereof for all purposes hereof unless and until the Agent
receives and accepts an Assignment and Acceptance executed in accordance with
Section 11.3(b) hereof.  As to any matters not expressly provided for by this
Credit Agreement, the Agent shall not be required to exercise any discretion
or take any action, but shall be required to act or to refrain from acting
(and shall be fully protected in so acting or refraining from acting) upon
the  instructions of the Required Lenders, and such instructions shall be
binding on all of the Lenders; provided, however, that the Agent shall not be
                               --------  -------
required to take any action that exposes the Agent to personal liability or
that is contrary to any Credit Document or applicable law or unless it shall
first be indemnified to its satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking any
such action.

      10.3  Defaults.
            --------

      The Agent shall not be deemed to have knowledge or notice of the
occurrence of a Default or Event of Default unless the Agent has received
written notice from a Lender or the Borrower specifying such Default or Event
of Default and stating that such notice is a "Notice of Default".  In the
event that the Agent receives such a notice of the occurrence of a Default or
Event of Default, the Agent shall give prompt notice thereof to the Lenders.
The Agent shall (subject to Section 10.2 hereof) take such action with
respect to such Default or Event of Default as shall reasonably be directed
by the Required Lenders, provided that, unless and until the Agent shall have
                         -------- ----
received such directions, the Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default
or Event of Default as it shall deem advisable in the best interest of the
Lenders.

      10.4  Rights as a Lender.
            ------------------

      With respect to its Commitment and the Loans made by it, NationsBank
(and any successor acting as Agent) in its capacity as a Lender hereunder
shall have the same rights and powers hereunder as any other Lender and may
exercise the same as though it were not acting as the Agent, and the term
"Lender" or "Lenders" shall, unless the context otherwise indicates, include
the Agent in its individual capacity. NationsBank (and any successor acting
as Agent) and its Affiliates may (without having to account therefor to any
Lender) accept deposits from, lend money to, make investments in, provide
services to, and generally engage in any kind of lending, trust, or other
business with any Credit Party or any of its Subsidiaries or Affiliates as if
it were not acting as Agent, and NationsBank (and any successor acting as
Agent) and its Affiliates may accept fees and other consideration from any
Credit Party or any of its Subsidiaries or Affiliates for services in
connection with this Credit Agreement or otherwise without having to account
for the same to the Lenders.

      10.5  Indemnification.
            ---------------

      The Lenders agree to indemnify the Agent (to the extent not reimbursed
under Section 11.5 hereof, but without limiting the obligations of the
Borrower under such Section) ratably in accordance with their respective
Commitments, for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including attorneys'
fees), or disbursements of any kind and nature whatsoever that may be imposed
on, incurred by or asserted against the Agent (including by any Lender) in
any way relating to or arising out of any Credit Document or the transactions
contemplated thereby or any action taken or omitted by the Agent under any
Credit Document; provided that no Lender shall be liable for any of the
                 --------
foregoing to the extent they arise from the gross negligence or willful
misconduct of the Person to be indemnified.  Without limitation of the
foregoing, each Lender agrees to reimburse the Agent promptly upon demand for
its ratable share of any costs or expenses payable by the Borrower under
Section 11.5, to the extent that the Agent is not promptly reimbursed for
such costs and


                                    59
<PAGE> 66

expenses by the Borrower. The agreements in this Section 10.5 shall survive
the repayment of the Loans, LOC Obligations and other obligations under the
Credit Documents and the termination of the Commitments hereunder.

      10.6  Non-Reliance on Agent and Other Lenders.
            ---------------------------------------

      Each Lender agrees that it has, independently and without reliance on
the Agent or any other Lender, and based on such documents and information as
it has deemed appropriate, made its own credit analysis of the Credit Parties
and their Subsidiaries and decision to enter into this Credit Agreement and
that it will, independently and without reliance upon the Agent or any other
Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under the Credit Documents.  Except for notices,
reports, and other documents and information expressly required to be
furnished to the Lenders by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition, or business of any
Credit Party or any of its Subsidiaries or Affiliates that may come into the
possession of the Agent or any of its Affiliates.

      10.7  Successor Agent.
            ---------------

      The Agent may resign at any time by giving notice thereof to the
Lenders and the Borrower.  Upon any such resignation, the Required Lenders
shall have the right to appoint a successor Agent.  If no successor Agent
shall have been so appointed by the Required Lenders and shall have accepted
such appointment within thirty (30) days after the retiring Agent's giving of
notice of resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent which shall be a commercial bank organized under
the laws of the United States of America having combined capital and surplus
of at least $100,000,000.  Upon the acceptance of any appointment as Agent
hereunder by a successor, such successor shall thereupon succeed to and
become vested with all the rights, powers, discretion, privileges, and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder.  After any retiring Agent's  resignation
hereunder as Agent, the provisions of this Section 10 shall continue in
effect for its benefit in respect of any actions taken or omitted to be taken
by it while it was acting as Agent.

      11.2  Right of Set-Off; Adjustments.
            -----------------------------

      Upon the occurrence and during the continuance of any Event of Default,
each Lender (and each of its Affiliates) is hereby authorized at any time and
from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by such
Lender (or any of its Affiliates) to or for the credit or the account of any
Credit Party against any and all of the obligations of such Person now or
hereafter existing under this Credit Agreement, under the Notes, under any
other Credit Document or otherwise, irrespective of whether such Lender shall
have made any demand under hereunder or thereunder and although such
obligations may be unmatured.  Each Lender agrees promptly to notify any
affected Credit Party after any such set-off and application made by such
Lender; provided, however, that the failure to give such notice shall not
        --------  -------
affect the validity of such set-off and application.  The rights of each
Lender under this Section  11.2  are in addition to other rights and remedies
(including, without limitation, other rights of set-off) that such Lender may
have.

      11.3  Benefit of Agreement.
            --------------------

            (a)    This Credit Agreement shall be binding upon and inure to
      the benefit of and be enforceable by the respective successors and
      assigns of the parties hereto; provided that none of the Credit Parties
                                     --------
      may assign or transfer any of its interests and obligations without
      prior written consent of the Lenders; provided further that the rights
                                            -------- -------
      of each Lender to transfer, assign or grant participations in its
      rights and/or obligations hereunder shall be limited as set forth in
      this Section 11.3.

            (b)    Each Lender may assign to one or more Eligible Assignees
      all or a portion of its rights and obligations under this Credit
      Agreement (including, without limitation, all or a portion of its
      Loans, its Notes, and its Commitment); provided, however, that
                                             --------  -------

                   (i)    each such assignment shall be to an Eligible
            Assignee;

                   (ii)   except in the case of an assignment to another
            Lender or an assignment of all of a Lender's rights and
            obligations under this Credit Agreement, any such partial
            assignment shall be in an amount at least equal to $1,000,000
            (or, if less, the remaining amount of the Commitment being
            assigned by such Lender) or an integral multiple of $1,000,000 in
            excess thereof;

                   (iii)  each such assignment by a Lender shall be of a
            constant, and not varying, percentage of all of its rights and
            obligations under this Credit Agreement and the Notes; and

                   (iv)   the parties to such assignment shall execute and
            deliver to the Agent for its acceptance an Assignment and
            Acceptance in the form of Exhibit 11.3(b) hereto, together with
                                      ---------------
            any Note subject to such assignment.

      Upon execution, delivery, and acceptance of such Assignment and
      Acceptance, the assignee thereunder shall be a party hereto and, to the
      extent of such assignment, have the obligations, rights, and benefits
      of a Lender hereunder and the assigning Lender shall, to the extent of
      such assignment, relinquish its rights and be released from its
      obligations under this Credit Agreement.  Upon the consummation of any
      assignment pursuant to this Section 11.3(b), the assignor, the Agent
      and Borrower shall make appropriate arrangements so that, if required,
      new Notes are issued to the assignor and the assignee.

            (c)    The Agent shall maintain at its address referred to in
      Section 11.1 a copy of each Assignment and Acceptance delivered to and
      accepted by it and a register for the recordation of the names


                                    61
<PAGE> 68

      and addresses of the Lenders and the Commitment of, and principal
      amount of the Loans owing to, each Lender from time to time (the
      "Register").  The entries in the Register shall be conclusive and
       --------
      binding for all purposes, absent manifest error, and Borrower, the
      Agent and the Lenders may treat each Person whose name is recorded in
      the Register as a Lender hereunder for all purposes of this Credit
      Agreement.  The Register shall be available for inspection by the
      Borrower or any Lender at any reasonable time and from time to time
      upon reasonable prior notice.

            (d)    Upon its receipt of an Assignment and Acceptance executed
      by the parties thereto, together with any Note subject to such
      assignment and payment of the processing fee, the Agent shall, if such
      Assignment and Acceptance has been completed and is in substantially
      the form of Exhibit 11.3(b) hereto, (i) accept such Assignment and
      Acceptance, (ii) record the information contained therein in the
      Register and (iii) give prompt notice thereof to the parties thereto.

            (e)    Each Lender may sell participations to one or more Persons
      in all or a portion of its rights and obligations under this Credit
      Agreement (including all or a portion of its Commitment and its Loans);
      provided, however, that  (i) such Lender's obligations under this
      --------  -------
      Credit Agreement shall remain unchanged, (ii) such Lender shall remain
      solely responsible to the other parties hereto for the performance of
      such obligations,  (iii) the participant shall be entitled to the
      benefit of the yield protection provisions contained in Section 3, and
      the right of set-off contained in Section 11.2, and (iv) the Borrower
      shall continue to deal solely and directly with such Lender in
      connection with such Lender's rights and obligations under this Credit
      Agreement, and such Lender shall retain the sole right to enforce the
      obligations of the Borrower relating to its Loans and its Notes and to
      approve any amendment, modification, or waiver of any provision of this
      Credit Agreement (other than amendments, modifications, or waivers
      decreasing the amount of principal of or the rate at which interest is
      payable on such Loans or Notes, extending any scheduled principal
      payment date or date fixed for the payment of interest on such Loans or
      Notes, or extending its Commitment).

            (f)    Notwithstanding any other provision set forth in this
      Credit Agreement, any Lender may at any time assign and pledge all or
      any portion of its Loans and its Notes to any Federal Reserve Bank as
      collateral security pursuant to Regulation A and any Operating Circular
      issued by such Federal Reserve Bank.  No such assignment shall release
      the assigning Lender from its obligations hereunder.

            (g)    Any Lender may furnish any information concerning Borrower
      or any of its Subsidiaries in the possession of such Lender from time
      to time to assignees and participants (including prospective assignees
      and participants), subject, however, to the provisions of Section 11.14
      hereof.

      11.4  No Waiver; Remedies Cumulative.
            ------------------------------

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

      11.5  Expenses; Indemnification.
            -------------------------

            (a)    The Borrower agrees to pay on demand all costs and
      expenses of the Agent in connection with the syndication, preparation,
      execution, delivery, administration, modification, and amendment of
      this Credit Agreement, the other Credit Documents, and the other
      documents to be delivered hereunder, including, without limitation, the
      reasonable fees and expenses of counsel for the Agent with respect
      thereto and with respect to advising the Agent as to its rights and
      responsibilities under the Credit Documents.  The fees (excluding
      expenses) of counsel to the Agent for the preparation, documentation
      and closing of the


                                    62
<PAGE> 69

      Revolving Credit Loan and Tranche A Term Loan will not exceed $42,000.
      The Borrower further agrees to pay on demand all costs and expenses of
      the Agent and the Lenders, if any (including, without limitation,
      reasonable attorneys' fees and expenses) in connection with the
      enforcement (whether through negotiations, legal proceedings, or
      otherwise) of the Credit Documents and the other documents to be
      delivered hereunder.

            (b)    The Borrower agrees to indemnify and hold harmless the
      Agent and each Lender and each of their Affiliates and their respective
      officers, directors, employees, agents, and advisors (each, an
      "Indemnified Party") from and against any and all claims, damages,
       -----------------
      losses, liabilities, costs, and expenses (including, without
      limitation, reasonable attorneys' fees) that may be incurred by or
      asserted or awarded against any Indemnified Party, in each case arising
      out of or in connection with or by reason of (including, without
      limitation, in connection with any investigation, litigation, or
      proceeding or preparation of defense in connection therewith) the
      Credit Documents, any of the transactions contemplated herein or the
      actual or proposed use of the proceeds of the Loans, except to the
      extent such claim, damage, loss, liability, cost, or expense is found
      in a final, non-appealable judgment by a court of competent
      jurisdiction to have resulted from such Indemnified Party's gross
      negligence or willful misconduct.  In the case of an investigation,
      litigation or other proceeding to which the indemnity in this Section
      11.5 applies, such indemnity shall be effective whether or not such
      investigation, litigation or proceeding is brought by the Borrower, its
      directors, shareholders or creditors or an Indemnified Party or any
      other Person or any Indemnified Party is otherwise a party thereto and
      whether or not the transactions contemplated hereby are consummated.
      The Borrower agrees not to assert any claim against the Agent, any
      Lender, any of their Affiliates, or any of their respective directors,
      officers, employees, attorneys, agents, and advisers, on any theory of
      liability, for special, indirect, consequential, or punitive damages
      arising out of or otherwise relating to the Credit Documents, any of
      the transactions contemplated herein or the actual or proposed use of
      the proceeds of the Loans.

            (c)    Without prejudice to the survival of any other agreement
      of the Borrower hereunder, the agreements and obligations of the
      Borrower contained in this Section 11.5 shall survive the repayment of
      the Loans, LOC Obligations and other obligations under the Credit
      Documents and the termination of the Commitments hereunder.

      11.6  Amendments, Waivers and Consents.
            --------------------------------

      Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is
in writing entered into by, or approved in writing by, the Required Lenders
and the Borrower, provided, however, that:

            hereunder,

                   (C)    reduce or waive the principal amount of any Loan or
            of any reimbursement obligation, or any portion thereof, arising
            from drawings under Letters of Credit,

                   (D)    increase the Commitment of a Lender over the amount
            thereof in effect (it being understood and agreed that a waiver
            of any Default or Event of Default or mandatory reduction in the
            Commitments shall not constitute a change in the terms of any
            Commitment of any Lender),

                   (E)    except as the result of or in connection with an
            Asset Disposition permitted by Section 8.5, release all or
            substantially all of the Collateral,

                   (F)    except as the result of or in connection with a

            under Section 8.4, release the Borrower or substantially all of
            the other Credit Parties from its or their obligations under the

                   (G)    amend, modify or waive any provision of this
            Section 11.6 or Section 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12,
            3.13, 3.14, 9.1(a), 11.2, 11.3, 11.5 or 11.9,

                   (H)    reduce any percentage specified in, or otherwise
            modify, the definition of Required Lenders, or

                   (I)    consent to the assignment or transfer by the
            Borrower (or another Credit Party) of any of its rights and
            obligations under (or in respect of) the Credit Documents except
            as permitted thereby;

            (2)    without the consent of the Required Lenders, there may not
      be an extension of time for or the amount or the manner of application
      of proceeds of any mandatory prepayment required by Section 3.3(b)(ii),
      (iii), (iv) or (v) hereof;

            (3)    without the consent of the Agent, no provision of Section

      required in certain circumstances as set forth above, (x) each Lender
      is entitled to vote as such Lender sees fit on any bankruptcy
      reorganization plan that affects the Loans, and each Lender
      acknowledges that the provisions of Section 1126(c) of the Bankruptcy
      Code supersedes the unanimous consent provisions set forth herein and
      (y) the Required Lenders may consent to allow a Credit Party to use
      cash collateral in the context of a bankruptcy or insolvency
      proceeding.

      11.7  Counterparts.
            ------------

      This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of
which shall constitute one and the same instrument.  It shall not be
necessary in making proof of this Credit Agreement to produce or account for
more than one such counterpart for each of the parties hereto.  Delivery by
facsimile by any of the parties hereto of an executed counterpart of this
Credit Agreement shall be as effective as an original executed counterpart
hereof and shall be deemed a representation that an original executed
counterpart hereof will be delivered.

      11.8  Headings.
            --------

      The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction

obligations under the Credit Documents and the termination of the Commitments
hereunder, and all representations and warranties made by the Credit Parties
herein shall survive delivery of the Notes and the making of the Loans
hereunder.

            (d)    Arbitration.  Any controversy or claim between or among
                   -----------
      the parties hereto including but not limited to those arising out of or
      relating to this Agreement, the Notes, and any other Loan Document and
      related instruments, agreements or documents, including any claim based
      on or arising from an alleged tort, shall be determined by binding
      arbitration in accordance with the federal arbitration act (or if not
      applicable, the applicable state law), the rules of practice and
      procedure for the arbitration of commercial disputes of
      J.A.M.S./endispute or any successor thereof ("J.A.M.S."), and the
      "Special Rules" set forth below.  In the event of any inconsistency,
      the Special Rules shall control.  Judgment upon any arbitration award
      may be entered in any court having jurisdiction.  Any party to this
      instrument, agreement or document may bring an action, including a
      summary or expedited proceeding, to compel arbitration of any
      controversy or claim to which this agreement applies in any court
      having jurisdiction over such action.

                   Special Rules.  The arbitration shall be conducted in the
                   -------------
      county of any Borrower's domicile at the time of the execution of
      this instrument, agreement or document and administered by
      J.A.M.S. who will appoint an arbitrator; if J.A.M.S. is unable or
      legally precluded from administering the arbitration, then the
      American Arbitration Association will serve.  All arbitration
      hearings will be commenced within 90 days of the demand for
      arbitration; further, the arbitrator shall only upon a showing of
      cause, be permitted to extend the commencement of such hearing
      for up to an additional 60 days.

                   Reservation of Rights.  Nothing in this arbitration shall
                   ---------------------
      be deemed to (i) limit the applicability of any otherwise
      applicable statutes of limitation or repose and any waivers
      contained in this


                                    65
<PAGE> 72

      instrument, agreement or document; or (ii) be a waiver by the
      Agent or Lenders of the protection afforded by 12 U.S.C. Sec. 91
      or any substantially equivalent state law; or (iii) limit the
      right of Agent or Lenders (A) to exercise self help remedies such
      as (but not limited to) setoff, or (B) to foreclose against real
      estate of personal property collateral, or (c) to obtain from a
      court provisional or ancillary remedies such as (but not limited
      to) injunctive relief, writ of possession or the appointment of a
      Receiver.  Agent and Lenders may exercise such self help rights,
      foreclosure upon such property, or obtain such provisional or
      ancillary remedies before, during or after the pendency of any
      arbitration proceeding brought pursuant to this instrument,
      agreement or document.  Neither this exercise of self help
      remedies nor the institution or maintenance of an action for
      foreclosure or provisional or ancillary remedies shall constitute
      a waiver of the right of any party, including the claimant in any
      such action, to arbitrate the merits of the controversy or claim
      occasioning resort to such remedies.

      11.11 Severability.
            ------------

      If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable
and the remaining provisions shall remain in full force and effect and shall
be construed without giving effect  to the illegal, invalid or unenforceable
provisions.

      11.12 Entirety.
            --------

      This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and
supersede all prior agreements and understandings, oral or written, if any,
including any commitment letters or correspondence relating to the Credit
Documents or the transactions contemplated herein and therein.

      11.13 Binding Effect; Termination.
            ---------------------------

            (a)    This Credit Agreement shall become effective at such time
      on or after the Closing Date when it shall have been executed by
      Borrower and the Agent, and the Agent shall have received copies hereof
      (telefaxed or otherwise) which, when taken together, bear the
      signatures of each Lender, and thereafter this Credit Agreement shall
      be binding upon and inure to the benefit of the Borrower, the Agent and
      each Lender and their respective successors and assigns.

            (b)    The term of this Credit Agreement shall be until no Loans,
      LOC Obligations or any other amounts payable hereunder or under any of
      the other Credit Documents shall remain outstanding, no Letters of
      Credit shall be outstanding, all of the Credit Party Obligations have
      been irrevocably satisfied in full and all of the Commitments hereunder
      shall have expired or been terminated.

      11.14 Confidentiality.
            ---------------

      The Agent and each Lender (each, a "Lending Party") agrees to keep
                                          -------------
confidential any information furnished or made available to it by the
Borrower pursuant to this Credit Agreement that is marked confidential;
provided that nothing herein shall prevent any Lending Party from disclosing
- --------
such information (a) to any other Lending Party or any Affiliate of any
Lending Party, or any officer, director, employee, agent, or advisor of any
Lending Party or Affiliate of any Lending Party, (b) to any other Person if
reasonably incidental to the administration of the credit facility provided
herein, (c) as required by any law, rule, or regulation, (d) upon the order
of any court or administrative agency, (e) upon the request or demand of any
regulatory agency or authority, (f) that is or becomes available to the
public or that is or becomes available to any Lending Party other than as a
result of a disclosure by any Lending Party prohibited by this Credit
Agreement, (g) in connection with any litigation to which such Lending Party
or any of its Affiliates may be a party, (h) to the extent necessary in
connection with the exercise of any remedy under this Credit Agreement or any
other Credit Document, and (i) subject to provisions substantially similar to
those contained in this Section 11.14, to any actual or proposed participant
or assignee.


                                    66
<PAGE> 73

      11.15 Conflict.
            --------

      To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document,
on the other hand, this Credit Agreement shall control.

      11.16 Oral Agreements.
            ---------------

      Oral agreements or commitments to loan money, extend credit or to
forbear from enforcing repayment of a debt including promises to extend or
renew such debt are not enforceable.  To protect you (Borrower) and us
(Creditor) from misunderstanding or disappointment, any agreements we reach
covering such matters are contained in this writing, which is the complete
and exclusive statement of the agreement between us, except as we may later
agree in writing to modify it.

      11.17 Collateral Insurance.
            --------------------

      Unless you (Borrower) provide evidence of the insurance coverage
required by your agreement with us, we (Agent) may purchase insurance at your
expense to protect our interests in your collateral.  This insurance may, but
need not, protect your interests.  The coverage that we purchase may not pay
any claim that you make or any claim that is made against you in connection
with the collateral.  You may later cancel any insurance purchased by us, but
only after providing evidence that you have obtained insurance as required by
our agreement.  If we purchase insurance for the collateral, you will be
responsible for the costs of that insurance, including the insurance premium,
interest and any other charges we may impose in connection with the placement
of the insurance, until the effective date of the cancellation or expiration
of the insurance.  The costs of the insurance may be added to your total
outstanding balance or obligation.  The costs of the insurance may be more
than the cost of insurance you may be able to obtain on your own.

      11.18 ESOP Loan; Subordination; Restatement of Loan.
            ---------------------------------------------

      ESOP Borrower and NationsBank ratify and confirm the ESOP Loan and
acknowledge that the terms and provisions thereof and the collateral therefor
are as reflected in the Loan Agreement.  NationsBank agrees and confirms that
the Liens held by NationsBank to secure the ESOP Loan Obligations, except for
the stock of EASI pledged by the ESOP Trust, shall be and are hereby made
junior and secondary to the Liens in favor of the Agent as evidenced by this
Agreement and the Collateral Documents.  NationsBank agrees to execute any
document or instrument further evidencing or confirming this subordination.
All of the terms, conditions and provisions of the Loan Agreement pertaining
to the Revolving Loans and the Term Loans are restated in their entirety by
this Credit Agreement.

      IN WITNESS WHEREOF, each of the parties hereto has caused a counterpart
of this Amended and Restated Credit Agreement to be duly executed and
delivered as of the date first above written.
