                                   BACKGROUND

     A.    Pursuant to that certain Amended and Restated Loan and Security
Agreement dated December 7, 1995, as subsequently amended (the "PRIOR LINE OF
CREDIT LOAN AGREEMENT"), Obligors (other than JSM and Peterson) requested and
Bank agreed, inter alia, to extend to the Borrowers (other than Panther, JSM
and Peterson) a line of credit which has, prior to the effective date of this
Agreement, been increased up to a maximum principal amount of Twelve Million
Dollars ($12,000,000.00).

     B.    Pursuant to those certain Surety Agreements dated December 7, 1995
(collectively, the "PRIOR SURETY AGREEMENTS"), Guarantors agreed to act as
surety for and guarantee the obligations of the Borrowers (other than Panther,
JSM and Peterson) under the Prior Line of Credit Loan Documents (as hereinafter
defined).  The Prior Line of Credit Loan Agreement, the Surety Agreements and
all other documents executed in connection therewith may hereinafter be
collectively referred to as the "PRIOR LINE OF CREDIT LOAN DOCUMENTS".

     C.    Pursuant to that certain Loan and Security Agreement dated April 11,
1997 (the "TERM LOAN AGREEMENT"), Obligors requested and Bank agreed, inter
alia, to extend to Obligors a term loan in the original principal amount of
Twenty-Five Million Dollars ($25,000,000.00) (the "TERM LOAN").  The Term Loan
Agreement and all other documents executed in connection therewith may
hereinafter be collectively referred to as the "TERM LOAN DOCUMENTS".  The
Prior Line of Credit Loan Agreement and the Term Loan Agreement may hereinafter
be collectively referred to as the "PRIOR LOAN AGREEMENTS".  The Prior Line of
Credit Loan Documents and the Term Loan Documents may hereinafter be
collectively referred to as the "PRIOR LOAN DOCUMENTS".  The Term Loan has been
repaid in full.
   8
     D.    Obligors and Bank have agreed to amend and restate the Prior Line of
Credit Loan Agreement (a) increasing the maximum principal amount to Thirty
Million Dollars ($30,000,000.00), (b) adding Panther, JSM and Peterson as co-
borrowers, (d) deleting Panther as a guarantor, (d) revising the financial
covenants, and (e) making the additional changes set forth herein, all on the
terms and conditions set forth herein.

     E.    Capitalized terms not otherwise defined herein will have the
meanings set forth therefor in SECTION 15 of this Agreement.

           NOW, THEREFORE, in consideration of the terms and conditions
contained herein, and of any extensions of credit now or hereafter made to or
for the benefit of Obligors by Bank, the parties hereto, intending to be
legally bound hereby, agree that the Prior Line of Credit Loan Agreement is
amended and restated to read in its entirety as follows:

           1.    GENERAL ACKNOWLEDGMENTS.

                 1.1   CONFIRMATION OF BACKGROUND.  Obligors hereby ratify,
confirm and acknowledge that the statements contained in the foregoing
background are true and complete in all material respects.

                 1.2   VALIDITY OF LIENS.  All liens and security interests
granted to Bank in the Prior Line of Credit Loan Documents are hereby ratified,
confirmed and continued, and shall secure all Bank Indebtedness and the
performance by Obligors of their respective obligations hereunder.  Subject to
the release provisions set forth in SECTION 5.4 below, all UCC-1 Financing
Statements previously executed by Obligors in favor of Bank shall continue to
be in full force and effect and shall continue to operate to perfect the liens
and security interests granted to Bank.

                 1.3   NO CHALLENGE TO ENFORCEMENT.  Obligors acknowledge and
agree that none of them has any defense, set-off, counterclaim or challenge
against the payment of any sums owing under the Prior Line of Credit Loan
Documents.

                 1.4   NO NOVATION OR SATISFACTION.  Obligors acknowledge and
agree that this Agreement constitutes the amendment and restatement of the
Prior Line of Credit Loan Agreement.  Except as expressly provided herein,
neither this Agreement nor any other agreement entered into in connection
herewith or pursuant to the terms hereof shall be deemed or construed to be a
compromise, satisfaction, reinstatement, accord and satisfaction, novation or
release of any of the Prior Line of Credit Loan Documents, or any rights or
obligations thereunder, or a waiver by Bank of any of its rights under the
Prior Line of Credit Loan Documents or at law or in equity.

                 1.5   CONSISTENCY.  The terms of this Agreement and the terms
set forth in the Prior Line of Credit Loan Documents and any other document
executed in connection herewith shall be, as far as possible, complementary and
read and interpreted so as to expand, rather than contract, all such terms and
conditions; provided, however, in the event of any inconsistency between





                                       2
   9
the terms and conditions set forth in this Agreement and the terms and
conditions set forth in the Prior Line of Credit Loan Documents, this Agreement
shall control.  It is expressly agreed that all collateral securing the Bank
Indebtedness is described in this Agreement and such descriptions supersede and
prevail over any contrary descriptions in any of the Loan Documents (including
the Prior Loan Documents).

           2.    THE  LINE; USE OF PROCEEDS.

                 2.1   LINE OF CREDIT.  Bank will establish for Borrowers for
and during the period from the date hereof and until June 30, 2000 (the
"CONTRACT PERIOD"), subject to the terms and conditions hereof, a revolving
line of credit (the "LINE") pursuant to which Bank will from time to time make
loans and other extensions of credit to Borrowers and issue letters of credit
in an aggregate amount not exceeding at any time Thirty Million Dollars
($30,000,000.00).  Within the limitations in this Agreement, Borrowers may
borrow, repay and reborrow under the Line.  The Line shall be subject to all
terms and conditions set forth in all of the Loan Documents which terms and
conditions are incorporated herein. Borrowers' obligation to repay the loans
and extensions of credit under the Line is evidenced by Borrowers' amended and
restated promissory note (the "LINE NOTE") in the face amount of Thirty Million
Dollars ($30,000,000.00), which shall be in form attached hereto as EXHIBIT
"A".  Each Borrower shall be jointly and severally liable for repayment of all
advances and extensions of credit under the Line (including without limitation
all letters of credit issued hereunder regardless of who is named as the
account party) and all other obligations of each Borrower hereunder and under
the Loan Documents.

                 2.2   METHOD OF ADVANCES.  On any Business Day, any Borrower
may request an advance under the Line by delivering to the Bank officer
designated by Bank no later than 2:30 p.m. Philadelphia time on the Business
Day such advance is requested to be funded, in accordance with such procedures
as Bank may from time to time require.  Subject to the terms and conditions of
this Agreement, Bank may make the proceeds of an advance available to a
Borrower by crediting such proceeds to such Borrower's deposit account with
Bank.  Such request may be by telephone, unless Bank has advised Borrowers that
written requests are required.  Bank may require prompt written confirmation of
any telephone request and additional back-up documentation, from time to time.
Each request for an advance under the Line shall be conclusively presumed to be
made by a person authorized by Borrowers to do so.

                 2.3   SAVINGS CLAUSE.  Anything contained in this Agreement or
any other Loan Documents to the contrary notwithstanding, the obligations of
each Borrower with respect to the repayment of the principal balance of the
Line shall be limited to the greater of:  (i) the aggregate amount of the
outstanding advances under the Line made to or for the benefit of such Borrower
plus the outstanding face amount of each letter of credit issued under the Line
for the account of such Borrower, or (ii) a maximum aggregate amount equal to
the largest amount that would not render such Borrower's obligations with
respect thereto subject to avoidance as a fraudulent transfer or conveyance
under Section 548 of Title 11 of the United States Code or any applicable
provisions of comparable state law (collectively, the "FRAUDULENT TRANSFER
LAWS"), if and to the extent such





                                       3
   10
Borrower (or trustee on its behalf) has properly invoked the protections of the
Fraudulent Transfer Laws.  In making such determination, all rights of
subrogation and contribution of a Borrower with respect to such obligations
shall be deemed to be an asset of such Borrower.

                 2.4   USE OF PROCEEDS.  Borrowers agree that the proceeds of
the Line may be used solely for working capital purposes and general corporate
purposes, to finance Permitted Acquisitions and to repay the Subordinated Term
Loan.

                 2.5   CLOSING.  Closing hereunder will take place at a time
and place mutually acceptable to Obligors and Bank effective on the date of
this Agreement.

                 2.6   LETTERS OF CREDIT.  Bank, at its sole discretion, may
issue for the account of one or more of the Borrowers standby letters of credit
in form and content satisfactory to Bank, at its sole discretion, with a term
not to exceed the earlier to occur of: (a) twelve (12) months, or (b) the
expiration of the Contract Period, unless fully secured by cash collateral as
hereinafter provided. Notwithstanding the foregoing, (i) at no time shall the
aggregate face amount of all outstanding letters of credit issued under the
Line exceed the amount of Four Million Dollars ($4,000,000.00); and (ii) at no
time shall the principal balance of the Line, plus the aggregate face amount of
all outstanding letters of credit issued under the Line exceed Thirty Million
Dollars ($30,000,000.00)  Borrowers acknowledge and agree that letter of credit
number S837746 in the face amount of Four Hundred Thousand Dollars
($400,000.00) dated December 20, 1994 and issued by Bank for the benefit of
IPSCO and letter of credit number S858718 in the face of One Million Two
Hundred Thousand Dollars ($1,200,000.00) dated June 1, 1998 and issued by Bank
shall be deemed to be standby letters of credit issued under the Line.

           Borrowers will execute a letter of credit application and letter of
credit agreement, and such other documents as may be required by Bank in
connection with the issuance of letters of credit hereunder.  The outstanding
face amount of all letters of credit issued by Bank pursuant hereto will reduce
each Borrower's ability to borrow under the Line as if such face amount were an
advance under the Line. In the event that Bank pays any sums due pursuant to
such letters of credit for any reason, such payment shall be deemed to be an
advance under the Line repayable by Borrowers pursuant to the terms hereof.

           In the event that the Line is terminated for any reason, the
Contract Period expires or demand is made thereunder, Borrowers will deposit
with Bank an amount equal to the undrawn face amount of all letters of credit
then outstanding which have been issued hereunder, plus all fees related
thereto or to accrue thereunder.  Such funds will be held by Bank as cash
collateral to secure Borrowers' obligations hereunder.

           3.    INTEREST RATE.

                 3.1   INTEREST ON THE LINE.

                       (a)   INTEREST OPTIONS.  The principal balance of the
Line will accrue interest at the Prime Rate in effect from time to time (such
interest rate to change effective immediately upon any change in the Prime
Rate), provided, however, that, subject to the terms of this SECTION 3.1, by
giving Notification, Borrowers may request to have one or more portions of the
outstanding balance of the Line as hereinafter permitted, accrue interest
instead at the LIBOR Based Rate as follows: (i) with respect to the principal
amount of any advance under the Line, from the date of such advance until the
end of the Rate Period specified in the Notification; and/or (ii) with respect
to the principal amount of any portion of the Line outstanding and accruing
interest at the LIBOR Based Rate at the time of the Notification related to
such principal amount, from the expiration of the then current Rate Period
related to such principal amount until the end of the Rate Period specified in
the Notification; and/or (iii) with respect to all or any portion of the
principal amount of the Line outstanding and accruing interest at the Prime
Rate at the time of Notification, from the date set forth in the Notification
until the end of the Rate Period specified in the Notification.

           Borrowers understand and agree: (A) that subject to the provisions
of this Agreement, the Prime Rate and the LIBOR Based Rate may apply
simultaneously to different parts of the outstanding principal of the Line, (B)
that different LIBOR Based Rates may apply simultaneously to various portions
of the outstanding principal of the Line for various Rate Periods, (C) that the
LIBOR Based Rate applicable to any portion of outstanding principal of the Line
may be different from the LIBOR Based Rate applicable to any other portion of
outstanding principal, (D) that portions of the Line accruing interest at a
LIBOR Based Rate must be in increments of Five Hundred Thousand Dollars
($500,000.00) each, and (E) that Bank shall have the right to terminate any
Rate Period and the LIBOR Based Rate interest rate applicable thereto, prior to
maturity of such Rate Period, if Bank determines in good faith (which
determination shall be conclusive) that continuance of such interest rate has
been made unlawful by any law, statute, rule or regulation, to which Bank may
be subject, in which event the principal to which such terminated Rate Period
relates thereafter shall earn interest at the Prime Rate.  Any termination of a
Rate Period by Bank pursuant to SUBSECTION  E) above shall be without premium,
penalty or charge to any of the Obligors.

           So long as (y) Borrowers comply with the conditions set forth herein
and (z) no Event of Default has occurred, Bank shall approve Borrowers' request
for a LIBOR Based Rate.

                       (b)   PRIME RATE FALL BACK.  After expiration of any
Rate Period, any principal portion of the Line accruing interest at a LIBOR
Based Rate corresponding to such Rate Period which has not been converted or
renewed to a LIBOR Based Rate in accordance with SECTION 3.1 shall accrue
interest automatically at the Prime Rate from the date of expiration of such
Rate Period until paid in full or until conversion to a LIBOR Based Rate in
accordance with SECTION 3.1.  With respect to any principal amount (whether an
advance of new funds or an already





                                       5
   12
outstanding amount), if there is no conversion to or renewal of a LIBOR Based
Rate, for any reason, such principal amount shall be deemed to accrue interest
at the Prime Rate.

                       (c)   INDEMNIFICATION.  Obligors shall indemnify Bank
against any loss or expense (including loss of margin) which Bank has sustained
or incurred as a consequence of: (i) any payment of any principal amount
accruing interest at the LIBOR Based Rate on a day other than the last day of
the corresponding Rate Period (whether or not any such payment is made pursuant
to acceleration upon or after an Event of Default, demand by Bank otherwise
made under this Agreement, by reason of an application of proceeds incident to
an insured loss or condemnation of property, or for any other reason, and
whether or not any such payment is consented to by Bank, unless Bank shall have
expressly waived such indemnity in writing); (ii) any attempt by any Borrower
to revoke in whole or part any Notification given pursuant to this Agreement;
(iii) any attempt by any Borrower to convert or renew any principal amount
accruing interest at the LIBOR Based Rate on a day other than the last day of
the corresponding Rate Period (whether or not such conversion or renewal is
consented to by Bank, unless Bank shall have expressly waived such indemnity in
writing or unless Bank shall have terminated the Rate Period pursuant to
SECTION 3.1(A)(E) above); (iv) any conversion of any amount earning interest at
the LIBOR Based Rate on a day other than the last day of the corresponding Rate
Period; or (v) any breach of or default by any Obligor.

                       (d)   SPECIAL REDUCTIONS TO LIBOR BASED RATE.  Borrowers
may cause a reduction in the LIBOR Based Rate if Obligors' Total Funded Debt to
EBITDA Ratio is reduced to a certain level.  Obligors' Total Funded Debt to
EBITDA Ratio will be tested as of the end of each fiscal quarter to determine
if Borrowers are eligible for such rate reduction.  In order to obtain such
rate reduction (i) Obligors shall have submitted to Bank their quarterly
financial statements for the applicable fiscal quarter or the annual audited
year-end financial statements required under SECTIONS 9.1 AND 9.2, together
with the applicable certifications required under SECTIONS 9.7 AND 9.8, and
(ii) no Event of Default or Default shall have occurred (unless waived by Bank
or the applicable covenant is amended to cure such Event of Default or
Default). The rate reduction shall become effective as of the beginning of each
Rate Period which commences after the end of the fiscal quarter for which
Obligors have complied with the applicable rate reduction test as shown by the
financial statements and certifications described in SUBSECTION (I) above.  In
the event that Obligors subsequently fail to meet the required test for
subsequent fiscal quarters, such reduction shall automatically be revoked until
such test is subsequently again satisfied.

           The required ratio and rate reduction at any applicable date of
determination are as follows: if Obligors' Total Funded Debt to EBITDA Ratio is
less than 1.0 to 1.0, the LIBOR Based Rate shall be reduced by 25 basis points.

                 3.2   DEFAULT INTEREST.  Interest will accrue on the
outstanding principal amount of the Line following the occurrence of an Event
of Default or expiration of the Contract Period at a rate per annum equal to
the sum of two percent (2%) plus the Prime Rate (the "DEFAULT RATE").





                                       6
   13
                 3.3   POST JUDGMENT INTEREST.  Any judgment obtained for sums
due hereunder or under the Loan Documents will accrue interest at the highest
applicable default rate set forth above until paid.

                 3.4   CALCULATION.  Interest will be computed on the basis of
a year of 365/366 days and paid for the actual number of days elapsed.

                 3.5   LIMITATION OF INTEREST TO MAXIMUM LAWFUL RATE.  In no
event will the rate of interest payable hereunder exceed the maximum rate of
interest permitted to be charged by applicable law (including the choice of law
rules) and any interest paid in excess of the permitted rate will be refunded
to Obligors.  Such refund will be made by application of the excessive amount
of interest paid against any sums outstanding hereunder and will be applied in
such order as Bank may determine.  If the excessive amount of interest paid
exceeds the sums outstanding, the portion exceeding the sums outstanding will
be refunded in cash by Bank.  Any such crediting or refunding will not cure or
waive any default by Obligors.  Obligors agree, however, that in determining
whether or not any interest payable hereunder exceeds the highest rate
permitted by law, any non-principal payment, including without limitation late
charges, will be deemed to the extent permitted by law to be an expense, fee,
premium or penalty rather than interest.

           4.    PAYMENTS AND FEES.

                 4.1   INTEREST PAYMENTS ON THE LINE.  Borrowers will pay
interest on the principal balance of the Line monthly, on the first day of each
calendar month commencing the first day of the first calendar month following
the date hereof.

                 4.2   PRINCIPAL PAYMENTS ON THE LINE.  Borrowers will pay the
outstanding principal balance of the Line, together with any accrued and unpaid
interest thereon, on the expiration of the Contract Period or, ON DEMAND after
the occurrence of an Event of Default.  Prior to the occurrence of an Event of
Default, all payments made by or for the benefit of Borrowers, to the extent
applied to reduce the principal balance of the outstanding advances under the
Line shall be applied first towards repayment of the balance accruing interest
at the Prime Rate, before any payments are made with respect to any portion of
the principal balance accruing interest at a LIBOR Based Rate.

                 4.3   CHANGE OF CONTROL.  Promptly and in any event within ten
(10) Business Days after the occurrence of any Change of Control, the Obligors
will give written notice of such transaction or event to Bank, which notice
shall state the date of such Change of Control, shall describe such Change of
Control in reasonable detail and shall contain an offer (i) to prepay the
unpaid balance of the Line, all interest thereon and all sums due in connection
therewith and (ii) to release the Bank from any further obligations to make
advances or issue letters of credit under the Line effective as of the date
specified therein (the "CHANGE IN CONTROL PREPAYMENT DATE"), which shall be a
Business Day not less than the earlier to occur of (a) one (1) Business Day
prior to the date upon which Obligors have offered to prepay the Subordinated
Term Loan as a result of such Change





                                       7
   14
of Control pursuant to the terms of Subordinated Debt Loan Documents, or (b)
thirty (30) Business Days after the date of the notice to Bank of such Change
of Control.  Bank shall have the option to require the Obligors to prepay all
or any part of the Line and all interest thereon, to secure the undrawn face
amount of all outstanding letters of credit issued under the Line with cash
collateral to be held by Bank and to terminate any further obligations of Bank
to make advances or issue letters of credit under the Line, and Obligors
hereby, jointly and severally, agree to make such payments and to terminate any
further obligations of Bank to make advances or issue letters of credit under
the Line.  Such option may be exercised by Bank by written notice to the
Obligors given no later than ten (10) days prior to the Change in Control
Prepayment Date, specifying the amount to be paid.  On the Change in Control
Prepayment Date, Obligors shall pay such amount to Bank and, if requested by
Bank, shall execute a termination of any further obligations of Bank to make
advances or issue letters of credit under the Line; provided that,
notwithstanding its exercise of the option herein provided, Bank may at any
time prior to the Change in Control Prepayment Date waive or revoke in whole or
in part by written notice to Obligors the exercise of its option hereunder.

                 4.4   LETTER OF CREDIT FEES.  For each issuance or renewal of
a standby letter of credit hereunder, Borrowers will pay to Bank its standard
per credit issuance fees plus an amount equal to one and one-half percent (1
1/2%) per annum of the undrawn face amount of such standby letter of credit,
payable quarterly in advance.  In addition, Borrowers shall pay such other fees
and charges in connection with the negotiation or cancellation of each standby
letter of credit as may be customarily charged by Bank.  Such fees shall be
computed on the basis of a year of 360 days.

                 4.5   LINE FEE.  In consideration of Bank extending the Line
to Borrowers, Borrowers shall pay to Bank a loan fee equal to One Hundred
Twelve Thousand Five Hundred Dollars ($112,500.00).  Such fee shall be payable
in full upon the execution of this Agreement.  Such fee shall not be refundable
in whole or in part, regardless of whether the full amount of the Line is ever
advanced.

                 4.6   UNUSED LINE FEE.  So long as the Line is outstanding and
has not been terminated and the Bank Indebtedness has not been satisfied in
full, Borrowers shall unconditionally pay to Bank a fee equal to one-fourth of
one percent (1/4%) per annum of the daily unused portion of the Line (which
shall be calculated as the difference between Thirty Million Dollars
($30,000,000.00) (or such greater amount if the maximum committed amount for
the Line is ever increased), minus the sum of (a) the outstanding principal
balance of cash advances under the Line, and (b) the outstanding undrawn amount
of letters of credit issued under the Line at the close of business on the date
such calculation is made), which fee shall be computed on a monthly basis in
arrears and shall be due and payable on the first day of each month commencing
on the first day of the first full month after the date hereof.

                 4.7   LATE CHARGE.  In the event that Obligors fail to pay
when due any principal, interest or other fees or expenses payable hereunder
for a period of at least fifteen (15) days, in addition to paying such sums,
Obligors will pay to Bank a late charge equal to two percent (2%) of such past
due payment as compensation for the expenses incident to such past due payment.





                                       8
   15
                 4.8   TERMINATION OF LINE.  Borrowers may terminate the Line
upon fifteen (15) days' written notice to Bank. In the event the Line is
terminated as a result of an Event of Default, expiration of the Contract
Period, or otherwise, the outstanding balance of the Line, together with any
accrued and unpaid interest thereon and any other sums due pursuant to the
terms hereof shall be due and payable immediately.

                 4.9   PREPAYMENT OF THE LINE.  Borrowers may prepay all or any
part of the principal balance of advances under the Line accruing interest at
the Prime Rate at any time, without any premium or fee.  Prepayment of any
advances under the Line accruing interest at a LIBOR Based Rate shall be
subject to the provisions of SECTION 3.1(C) and SECTION 4.13.  In the event
Bank exercises its right to accelerate payments under the Line following an
Event of Default or otherwise, any tender of payment of the amount necessary to
repay the principal balance of the Line made thereafter at any time by any
Obligor, its successors or assigns or by anyone on behalf of any Obligor shall
be deemed to be a voluntary prepayment and in connection therewith Bank shall
be entitled to receive any sums required to be paid under the foregoing
prepayment restrictions.

                 4.10  PAYMENT METHOD.  Obligors irrevocably authorize Bank to
debit all payments required to be made by Obligors hereunder or under the Line,
on the date due, from any deposit account maintained by any Obligor with Bank.
Otherwise, Obligors will be obligated to make such payments directly to Bank.
All payments are to be made in immediately available funds.  If Bank accepts
payment in any other form, such payment shall not be deemed to have been made
until the funds comprising such payment have actually been received by or made
available to Bank.

                 4.11  APPLICATION OF PAYMENTS.  Any and all payments on
account of the Line will be applied first to accrued and unpaid interest, then
to unpaid principal of Prime Rate loans, then to unpaid principal of LIBOR
Based Rate loans, then to other sums due hereunder or under the Loan Documents.
Upon the occurrence of an Event of Default, Bank may apply such payments in
such order as Bank, in its discretion, elects, provided that Bank will use its
best efforts to minimize prepayment of LIBOR Based Rate loans prior to the
expiration of the applicable Rate Period.  If Obligors make a payment or
payments and such payment or payments, or any part thereof, are subsequently
invalidated, declared to be fraudulent or preferential, set aside or are
required to be repaid to a trustee, receiver, or any other person under any
bankruptcy act, state or federal law, common law or equitable cause, then to
the extent of such payment or payments, the obligations or part thereof
hereunder intended to be satisfied shall be revived and continued in full force
and effect as if said payment or payments had not been made.

                 4.12  LOAN ACCOUNT.  Bank will open and maintain on its books
a loan account (the "LOAN ACCOUNT") with respect to advances made, repayments,
prepayments, the computation and payment of interest and fees and the
computation and final payment of all other amounts due and sums paid to Bank
under this Agreement. Except in the case of manifest error in computation, the
Loan Account will be presumed correct as to the amount at any time due to Bank
from Obligors under this Agreement or the Line.





                                       9
   16
                 4.13  INDEMNITY; LOSS OF MARGIN.  Obligors will indemnify Bank
against any loss or expense which Bank sustains or incurs as a consequence of
an Event of Default, including, without limitation, any failure of Obligors to
pay when due (at maturity, by acceleration or otherwise) any principal,
interest, fee or any other amount due under this Agreement or the other Loan
Documents. If Bank sustains or incurs any such loss or expense it will from
time to time notify Obligors in writing of the amount reasonably determined in
good faith by the Bank to be necessary to indemnify Bank for the loss or
expense.  Such amount will be due and payable by Obligors to Bank within ten
(10) days after presentation by Bank of a statement setting forth a brief
explanation of and Bank's calculation of such amount, which statement shall be
presumed correct absent manifest error.  Any amount payable to the Bank under
this Section will bear interest at the Default Rate from the due date until
paid, both before and after judgment.

           In the event that any future law, rule, regulation, treaty or
official directive, interpretation or application by any central bank, monetary
authority or governmental authority, or the future compliance with any
guideline or request of any central bank, monetary authority or governmental
authority (whether or not having the force of law):

                       (a)   subjects Bank (or any LIBOR-rate funding office of
or utilized by Bank in connection with any portion of the Line) to any tax with
respect to any amounts payable under this Agreement or the other Loan Documents
by Obligors or otherwise with respect to the transactions contemplated under
this Agreement or the other Loan Documents (except for taxes on or determined
by the overall net income of Bank imposed by the United States of America or
any political subdivision thereof); or

                       (b)   imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit, capital maintenance, capital adequacy, or
similar requirement against assets held by, or deposits in or for the account
of, or loans or advances or commitment to make loans or advances by the Bank
(or any LIBOR-rate funding office of or utilized by Bank in connection with any
portion of the Line); or

                       (c)   imposes upon Bank (or any LIBOR-rate funding
office of or utilized by Bank in connection with any portion of the Line) any
other condition with respect to advances or extensions of credit or the
commitment to make advances or extensions of credit under this Agreement, and
the result of any of the foregoing is to increase the costs of Bank (or any
LIBOR-rate funding office of or utilized by Bank in connection with any portion
of the Line), reduce the income receivable by or return on equity of Bank (or
any LIBOR-rate funding office of or utilized by Bank in connection with any
portion of the Line) or impose any expense upon Bank (or any LIBOR-rate funding
office of or utilized by Bank in connection with any portion of the Line) with
respect to any advances or extensions of credit or commitments to make advances
or extensions of credit under this Agreement, Bank shall so notify Obligors in
writing.  Obligors agree to pay Bank the amount of such increase in cost,
reduction in income, reduced return on equity or capital, or additional expense
within ten (10) days after presentation by Bank of a statement concerning such





                                       10
   17
increase in cost, reduction in income, reduced return on equity or capital, or
additional expense. Such statement shall set forth a brief explanation of the
amount and Bank's calculation of the amount (in determining such amount the
Bank may use any reasonable averaging and attribution methods), which statement
shall be presumed correct absent manifest error.  If the amount set forth in
such statement is not paid within ten (10) days after such presentation of such
statement, interest will be payable on the unpaid amount at the highest default
rate payable under the Loans from the due date until paid, both before and
after judgment.

           5.    SECURITY.

                 5.1   PERSONAL PROPERTY.  As security for the full and timely
payment and performance of the Bank Indebtedness, each Obligor hereby ratifies
and confirms the security interest granted to Bank in the Prior Line of Credit
Loan Documents (except as provided in SECTION 5.4 below) and hereby grants to
Bank a security interest in all of the following:

                       (a)   All of such Obligor's present and future accounts,
contract rights, chattel paper, instruments and documents and all other rights
to the payment of money whether or not yet earned, for services rendered or
goods sold, consigned, leased or furnished by such Obligor or otherwise,
together with (i) all goods (including any returned, rejected, repossessed or
consigned goods), the sale, consignment, lease or other furnishings of which
shall be given or may give rise to any of the foregoing, (ii) all of such
Obligor's rights as a consignor, consignee, unpaid vendor or other lienor in
connection therewith, including stoppage in transit, set-off, detinue, replevin
and reclamation, (ill) all general intangibles related thereto, (iv) all
guaranties, mortgages, security interests, assignments, and other encumbrances
on real or personal property, leases and other agreements or property securing
or relating to any accounts, (v) choses-in-action, claims and judgments, (vi)
any return or unearned premiums, which may be due upon cancellation of any
insurance policies, and (vii) all products and proceeds of any of the
foregoing.

                       (b)   All of such Obligor's present and future inventory
(including but not limited to goods held for sale or lease or furnished or to
be furnished under contracts for service, raw materials, work-in-process,
finished goods and goods used or consumed in such Obligor's business) whether
owned, consigned or held on consignment, together with all merchandise,
component materials, supplies, packing, packaging and shipping materials, and
all returned, rejected or repossessed goods sold, consigned, leased or
otherwise furnished by such Obligor, all documents of title covering any of
such goods or inventory and all products and proceeds of any of the foregoing.
Notwithstanding anything herein or elsewhere in this Agreement to the contrary,
the security interests granted in this SUBSECTION (B) shall not attach to or
encumber or constitute a lien upon the Obligor's drilling rigs, drilling
equipment and drill pipe.

                       (c)   All of such Obligor's right, title and interest in
and to present and future general intangibles constituting proceeds of any
assets described in SUBSECTIONS (A) AND (B) above.





                                       11
   18
                       (d)   All of such Obligor's present and future general
ledger sheets, files, records, customer lists, books of account, invoices,
bills, certificates or documents of ownership, bills of sale, business papers,
correspondence, credit files, tapes, cards, computer runs and all other data
and data storage systems whether in the possession of any Obligor or any
service bureau.

                       (e)   All letters of credit now existing or hereafter
issued naming any Obligor as a beneficiary or assigned to any Obligor,
including the right to receive payment thereunder, and all documents and
records associated therewith.

instruments, documents, policies, evidences and certificates of insurance of
such Obligor or in which such Obligor has an interest and all proceeds thereof,
on deposit with or in the possession or control of Bank or owing by Bank to
such Obligor or in transit by mail or carrier to Bank or in the possession of
any other Person acting on Bank's behalf, without regard to whether Bank
received the same in pledge, for safekeeping, as agent for collection or
otherwise, or whether Bank has conditionally released the same, and in all
assets of such Obligor in which Bank now has or may at any time hereafter
obtain a lien, mortgage, or security interest for any reason.

                       (g)   All proceeds of the foregoing.

                 5.2   SURETY.  As further security for the Bank Indebtedness,
Guarantors shall execute and deliver to Bank their unconditional, unlimited
surety agreements in form and content acceptable to Bank (the "SURETY
AGREEMENTS").

                 5.3   GENERAL.  The collateral described above in SECTION 5.1
is collectively referred to herein as the "COLLATERAL".  The above-described
security interests and liens shall not be rendered void by the fact that no
Bank Indebtedness exists as of any particular date, but shall continue in full
force and effect until all Bank Indebtedness has been repaid and Bank has no
agreement or commitment outstanding pursuant to which Bank may extend credit to
or on behalf of any Obligor.  IT IS THE EXPRESS INTENT OF THE OBLIGORS THAT ALL
OF THE COLLATERAL SHALL SECURE NOT ONLY THE OBLIGATIONS UNDER THE LOAN
DOCUMENTS, BUT ALSO ALL OTHER PRESENT AND FUTURE OBLIGATIONS (NOW EXISTING OR
HEREAFTER ARISING) OF EACH OBLIGOR TO BANK.  Obligors acknowledge and agree
that (except as provided in SECTION 5.4 below) all security interests granted
to Bank pursuant to the Prior Line of Credit Loan Documents are continued and
remain in effect, that the Bank's lien position with respect to the Collateral
shall relate back to the respective dates referenced in the Prior Line of
Credit Loan Documents and that all financing statements previously filed with
respect to the Collateral shall remain in full force and effect.

                 5.4   RELEASE OF CERTAIN COLLATERAL.  Bank hereby agrees that
its liens and security interests in the assets of Obligors shall only extend to
the collateral described in SECTION 5.1 above and hereby releases its lien and
security interests in all other assets of Obligors.  Notwithstanding anything
herein or elsewhere in this Agreement to the contrary, the security interests





                                       12
   19
granted in SECTION 5.1 above shall not attach to or encumber or constitute a
lien upon the Obligors' drilling rigs, drilling equipment and drill pipe.

                 5.5   COLLECTION OF RECEIVABLES; PROCEEDS OF COLLATERAL.

                       (a)   Obligors will collect their accounts receivable
only in the ordinary course of business.  Prior to the occurrence of an Event
of Default, such accounts receivable shall be deposited in operating accounts
maintained by Obligors to be ultimately transferred to a deposit account
maintained with the Bank. Upon request by Bank after occurrence of an Event of
Default, Obligors will notify all of their account debtors to forward all
accounts receivable collections owed to Obligors to a lockbox maintained by
Bank and will forward all other checks, drafts and monies received by Obligors
which are proceeds of the Collateral to such lockbox. In connection therewith,
Obligors will execute such lockbox agreements as may be required by Bank and
will pay to Bank all customary fees in connection with any lockbox arrangement.

                       (b)   For purposes of perfecting Bank's security
interest, Obligors agree that all monies, checks, notes, instruments, drafts or
other payments relating to or constituting proceeds of any accounts receivable
or other Collateral of Obligors which come into the possession or under the
control of Obligors or any employees, agents or other persons acting for or in
concert with Obligors, shall be received and held in trust for Bank. For
purposes of perfecting Bank's security interest, Obligors shall deliver or
cause to be delivered to Bank, with appropriate endorsement and assignment to
Bank with full recourse to Obligors, all instruments, notes and chattel paper
constituting an account receivable or proceeds thereof or other Collateral.
Bank is hereby authorized to open all mail addressed to any Obligor and endorse
all checks, drafts or other items for payment on behalf of any Obligor. Bank is
granted a power of attorney by each Obligor with full power of substitution to
execute on behalf of such Obligor and in such Obligor's name or to endorse such
Obligor's name on any check, draft, instrument, note or other item of payment
or to take any other action or sign any document in order to effectuate the
foregoing. Such power of attorney being coupled with an interest is
irrevocable.

           6.    REPRESENTATIONS AND WARRANTIES.  Obligors represent and
warrant as follows:

                 6.1   VALID ORGANIZATION, GOOD STANDING AND QUALIFICATION.
Each Obligor is a corporation duly incorporated, validly existing and in good
standing under the laws of the state of its incorporation, has full power and
authority to execute, deliver and comply with the Loan Documents, and to carry
on its business as it is now being conducted and is duly licensed or qualified
as a foreign corporation in good standing under the laws of each jurisdiction
in which the character or location of the properties owned by it or that
business transacted by it requires such licensing or qualification, except
where the failure to be so licensed or qualified would not have a material
adverse effect on the Collateral, assets, business, operations or financial
condition of an Obligor or its ability to perform its obligations under the
Loan Documents.





                                       13
   20
                 6.2   LICENSES.  Obligors and their employees, servants and
agents have all licenses, registrations, approvals and other authority as may
be necessary to enable them to own and operate their business and perform all
services and business for the Obligors which they have agreed to perform in any
state, municipality or other jurisdiction, except where the failure to have
such licenses, registrations, approvals or other authority would not have a
material adverse effect on the Collateral, assets, business, operations or
financial condition of an Obligor or its ability to perform its obligations
under the Loan Documents.

                 6.3   OWNERSHIP INTERESTS.  The ownership of all stock,
debentures, options, warrants, bonds and other securities (debt and equity) of
Obligors (other than UTI) and all pledges, proxies, voting trusts, powers of
attorney and other agreements affecting the ownership or voting rights of said
interests is as set forth on SCHEDULE 6.3 attached hereto.  SCHEDULE 6.3 also
sets forth, to the best of Obligors' knowledge, as of April 28, 1998 the
ownership interests in UTI of all Persons (including without limitation Remy)
who own 10% or more of the outstanding and issued stock of UTI.

                 6.4   SUBSIDIARIES.  Except as set forth on SCHEDULE 6.4
attached hereto, no Obligor owns any shares of stock or other equity interests
in any Person, directly or indirectly (by any Subsidiary or otherwise).

                 6.5   FINANCIAL STATEMENTS. Obligors have furnished to Bank
the audited consolidated and the unaudited consolidating financial statements
of Obligors certified without qualification by independent public accountants
for the fiscal year ending as of December 31, 1997 and all management and
comment letters from such accountants in connection therewith. Such financial
statements (together with the related notes and comments), are materially
correct and complete, fairly present the financial condition and the assets and
liabilities of Obligors at such date, and have been prepared in accordance with
GAAP in all material respects.

                 6.6   NO MATERIAL ADVERSE CHANGE IN FINANCIAL CONDITION.
There has been no material adverse change in the financial condition of
Obligors taken as a whole since December 31, 1997.

                 6.7   PENDING LITIGATION OR PROCEEDINGS.  Except as set forth
on SCHEDULE 6.7 attached hereto, there are no judgments outstanding or actions,
suits or proceedings pending or, to the best of Obligors' knowledge, threatened
by written notice against or affecting any Obligor, at law or in equity or
before or by any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign,
which in the aggregate, if finally determined adversely to any Obligor would
reasonably be expected to result in a judgment or liability in excess of Five
Hundred Thousand Dollars ($500,000.00), or which individually or in the
aggregate may materially and adversely affect any of their business activities,
properties or financial condition, their right to carry on business activities
as now conducted, or their ability to perform their respective obligations
under this Agreement or the Loan Documents.





                                       14
   21
                 6.8   DUE AUTHORIZATION; NO LEGAL RESTRICTIONS.  The execution
and delivery by Obligors of the Loan Documents, the consummation of the
transactions contemplated by the Loan Documents and the fulfillment and
compliance with the respective terms, conditions and provisions of the Loan
Documents: (a) have been duly authorized by all requisite corporate action of
each Obligor, (b) will not conflict with or result in a breach of, or
constitute a default (or might, upon the passage of time or the giving of
notice or both, constitute a default) under, any of the terms, conditions or
provisions of any applicable statute, law, rule, regulation or ordinance or any
Obligor's Certificate or Articles of Incorporation or By-Laws or any indenture,
mortgage, loan or credit agreement or instrument to which any Obligor is a
party or by which any of them may be bound or affected, or any judgment or
order of any court or governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, and (c) will not result in the
creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon any of the property or assets of any Obligor under the terms or
provisions of any such agreement or instrument, except liens in favor of Bank.

                 6.9   ENFORCEABILITY.  The Loan Documents have been duly
executed by Obligors and delivered to Bank and constitute legal, valid and
binding obligations of Obligors, enforceable in accordance with their terms.

                 6.10  NO DEFAULT UNDER OTHER OBLIGATIONS, ORDERS OR
GOVERNMENTAL REGULATIONS.  No Obligor is in violation of its Certificate or
Articles of Incorporation or in default in the performance or observance of any
of its obligations, covenants or conditions contained in any indenture or other
agreement creating, evidencing or securing any Indebtedness or pursuant to
which any such Indebtedness is issued or under any other agreement or
instrument or any judgment, decree, order, statute, rule or governmental
regulation, applicable to it or by which its properties may be bound or
affected, except such violations or defaults which do not have a material
adverse effect on the Collateral, assets, business, operations or financial
condition of an Obligor or its ability to perform its obligations under the
Loan Documents.

                 6.11  CONSENTS.  No consent, approval or authorization of or
designation, declaration or filing (other than the filing of financing
statements) with any governmental authority or any other Person on the part of
any Obligor is required in connection with the execution, delivery or
performance by any Obligor of the Loan Documents or the consummation of the
transactions contemplated thereby.

                 6.12  TAXES.  Obligors have filed all tax returns which they
are required to file and have paid, or made provision for the payment of, all
taxes which have or may have become due pursuant to such returns or pursuant to
any assessment received by them, except such taxes (other than real estate
taxes which must be paid regardless of challenge), if any, as are being
contested in good faith and as to which adequate reserves have been provided
and except where the failure to file such a tax return would not have a
material adverse effect on the Collateral, assets, business, operations or
financial condition of an Obligor or its ability to perform its obligations
under the Loan





                                       15
   22
Documents. Such tax returns are complete and accurate in all material respects.
No Obligor knows of any proposed additional assessment or basis for any
assessment of additional taxes.

                 6.13  TITLE TO COLLATERAL.  The Collateral (including without
limitation all assets acquired pursuant to the Permitted Acquisitions) is and
will be owned by Obligors free and clear of all liens and other encumbrances of
any kind (including liens or other encumbrances upon properties acquired or to
be acquired under conditional sales agreements or other title retention
devices), excepting only liens in favor of the Bank and those liens and
encumbrances permitted under SECTION 7.9 below. Obligors will defend the
Collateral against any claims of all Persons other than the Bank.

                 6.14  ADDRESSES.  During the past five (5) years, no Obligor
has been known by any names (including trade names) other than those set forth
in SCHEDULE 6.14 attached hereto and no Obligor has been located at any
addresses other than those set forth on SCHEDULE 6.14 attached hereto. The
portions of the Collateral which are tangible property and each Obligor's books
and records pertaining thereto will at all times be located at the addresses
set forth on SCHEDULE 6.14; or such other location determined by Obligors after
prior notice to Bank and delivery to Bank of any items requested by Bank to
maintain perfection and priority of Bank's security interests and access to
Obligors' books and records.  SCHEDULE 6.14 identifies the chief executive
office of each Obligor.

                 6.15  CURRENT COMPLIANCE.  Obligors are currently in
compliance with all of the terms and conditions of the Loan Documents.

                 6.16  PENSION PLANS.  Except as disclosed on SCHEDULE 6.16
hereto, (a) no Obligor has any obligations with respect to any employee pension
benefit plan ("PLAN") (as such term is defined in the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")), (b) no events, including,
without limitation, any "Reportable Event" or "Prohibited Transaction" (as
those terms are defined under ERISA), have occurred in connection with any Plan
of any Obligor which might constitute grounds for the termination of any such
Plan by the Pension Benefit Guaranty Corporation ("PBGC") or for the
appointment by any United States District Court of a trustee to administer any
such Plan, (c) all of the Obligors' Plans meet with the minimum funding
standards of Section 302 of ERISA, and (d) no Obligor has existing liability to
the PBGC. No Obligor is subject to or bound to make contributions to any
"multi-employer plan" as such term is defined in Section 4001(a)(3) of ERISA.

                 6.17  LEASES AND CONTRACTS.  Obligors have complied in all
material respects with the provisions of all material leases, contracts or
commitments of any kind (such as employment agreements, collective bargaining
agreements, powers of attorney, distribution agreements, patent license
agreements, contracts for future purchase or delivery of goods or rendering of
services, bonus, pension and retirement plans or accrued vacation pay,
insurance and welfare agreements) to which they are a party and are not in
default thereunder. To the best of Obligors' knowledge, no other party is in
default in any material respect under any such leases, contracts or other
commitments and no





                                       16
   23
event has occurred which, but for the giving of notice or the passage of time
or both, would constitute an event of default thereunder.

                 6.18  INTELLECTUAL PROPERTY.  Each Obligor owns or possesses
the irrevocable right to use all of the patents, trademarks, service marks,
trade names, filed or registered copyrights, licenses, franchises and permits
and rights with respect to the foregoing necessary to own and operate its
properties and to carry on its business as presently conducted and presently
planned to be conducted without conflict with the rights of others.  SCHEDULE
6.18 sets forth an accurate list and description of each such patent,
trademark, service mark, trade name, filed or registered copyright, license,
franchise and permit and right with respect to the foregoing, together with all
registration or application numbers or information with respect thereto.

                 6.19  BUSINESS INTERRUPTIONS.  Within five (5) years prior to
the date hereof, neither the business, Collateral nor operations of any Obligor
have been materially and adversely affected in any way by any casualty, strike,
lockout, combination of workers, order of the United States of America, or any
state or local government, or any political subdivision or agency thereof,
directed against that Obligor. There are no pending or threatened labor
disputes, strikes, lockouts or similar occurrences or grievances against the
business being operated by any Obligor.

                 6.20  INTERRELATEDNESS OF OBLIGORS.  The business operations
of Obligors are interrelated and complement one another and such entities have
a common business purpose, with intercompany bookkeeping and accounting
adjustments used to separate their respective properties, liabilities, and
transactions. To permit their uninterrupted and continuous operations, such
entities now require and will from time to time hereafter require funds and
credit accommodations for general business purposes. The proceeds of advances
under the Line and credit facilities extended hereunder will directly or
indirectly benefit each Obligor hereunder, severally and jointly, regardless of
which Borrower requests or receives part or all of the proceeds of the
advances.

                 6.21  ACCURACY OF REPRESENTATIONS AND WARRANTIES.  No
representation or warranty by Obligors contained herein or in any certificate
or other document furnished by Obligors pursuant hereto or in connection
herewith fails to contain any statement of material fact necessary to make such
representation or warranty not misleading in any material respect in light of
the circumstances under which it was made. There is no fact which any Obligor
knows and has not disclosed to Bank, which does or may materially and adversely
affect any Obligor or any of their operations.

                 6.22  SOLVENCY.  After giving effect to the transactions
contemplated by the Loan Documents, this Agreement and the Subordinated Debt
Loan Documents, (a) the fair market value of the assets of each Obligor is in
excess of the total amount of its liabilities (including, without limitation,
contingent liabilities); (b) the present fair saleable value of the assets of
each Obligor is greater than its probable liability on its existing debts as
such debts become absolute and matured; (c) each Obligor is able and expects to
be able to pay its debts (including, without limitation, contingent





                                       17
   24
debts and other commitments) as they mature; and (d) each Obligor has capital
sufficient to carry on its business as conducted and as proposed to be
conducted.

                 6.23  SUBORDINATED TERM LOAN.  No event of default or event
which, with the giving of notice, passage of time or both, has occurred and is
continuing under the Subordinated Debt Loan Documents, which would constitute
an event of default under the Subordinated Debt Loan Documents.  As of the date
hereof, the outstanding principal balance of the Subordinated Term Loan is
$25,000,000.00.

           7.    GENERAL COVENANTS.  Except with the prior written consent of
Bank, Obligors will comply with the following:

                 7.1   PAYMENT OF PRINCIPAL, INTEREST AND OTHER AMOUNTS DUE.
Each Obligor will pay when due all Bank Indebtedness and all other amounts
payable by such Obligor hereunder.

                 7.2   LIMITATION ON SALE AND LEASEBACK.  No Obligor will enter

value in the aggregate of more than $1,000,000.00, and then or thereafter rent
or lease as lessee such property, improvements or assets or any part thereof,
for substantially the same purposes as the property, improvements or assets
sold or transferred.

sale of assets is permitted under this Agreement;

                             (ix)  Indebtedness that refinances, renews,

                             (x)   Indebtedness arising from the honoring by a
bank or other financial institution of a check, draft or similar instrument
inadvertently drawn against insufficient funds in the ordinary course of
business; provided that, such Indebtedness is extinguished within two (2)

                             (xi)  Indebtedness for borrowed money for which an

Capitalized Lease Obligations in excess of (i) $500,000, individually, or (ii)
$1,500,000 in the aggregate for all such liabilities involve documents
containing financial covenants which are more restrictive with respect to any
Obligor than the financial covenants of this Agreement and the other Loan

include such more restrictive financial covenants as Bank may elect.

                       (c)   No intercreditor agreements shall be required with

                             (ii)  a liability for which recourse to any

           With respect to all other permitted purchase money Indebtedness and

a lien or charge upon any of its properties or assets; provided that it shall
not be required to pay any such tax (other than real estate taxes which must be
paid regardless of challenge), assessment, charge, levy or claim so long as the
validity thereof shall be contested in good faith by appropriate proceedings
promptly initiated and diligently conducted by it, and neither execution nor
foreclosure sale or similar proceedings shall have been commenced in respect
thereof (or such proceedings shall have been stayed pending the disposition of
such contest of validity), and it shall have set aside on its books, or at the
request of Bank deposited with Bank, adequate reserves with respect thereto.

SUBSECTION (F) only if (i) no Event of Default has occurred and is continuing,
and (ii) any action taken by any Obligor which would constitute a permitted
exception would not cause or result in an Event of Default.

           To the extent that any Indebtedness secured by a lien permitted
under SUBSECTIONS (E) OR (F) is refinanced, renewed, extended or refunded, such
liens may continue to secure the refinancing, renewal, extended or refunded
Indebtedness.

           No Obligor shall enter into any agreement with any other Person
which shall prohibit the Obligor from granting, creating or suffering to exist,
or otherwise restrict in any way (whether by covenant, by identifying such
event as a default under such agreement or otherwise) the ability of that

Obligors shall not be permitted to create, incur or permit to exist any
encumbrance, lien or security interest against or in any of the Collateral,
provided that, if an encumbrance, lien or security interest arises not as a
result of an Obligor executing a security, pledge or similar agreement, and

Obligors shall have a period of fifteen (15) days after the earlier of (i) any
Obligor receives notice that such an encumbrance, lien or security interest is
being claimed or asserted, or (ii) a responsible officer of any Obligor has

   33
                 7.10  EXISTENCE; APPROVALS; QUALIFICATION; BUSINESS
OPERATIONS; COMPLIANCE WITH LAWS.  Each Obligor (a) will obtain, preserve and
keep in full force and effect its separate corporate existence and all rights,
licenses, registrations and franchises necessary to the proper conduct of its
business or affairs; (b) will qualify and remain qualified as a foreign
corporation in each jurisdiction in which the character or location of the
properties owned by it or the business transacted by it requires such
qualification, except where the failure to be so qualified would not have a
material adverse effect on the Collateral, assets, business, operations or
financial condition of an Obligor or its ability to perform its obligations
under the Loan Documents; (c) will continue to operate its business as
presently operated and will not engage in any new businesses outside of Lines
of Business without the prior written consent of Bank; and (d) will comply in
all material respects with the requirements of all applicable laws and all
rules, regulations (including environmental regulations) and orders of
regulatory agencies and authorities having jurisdiction over it.

                 7.11  MAINTENANCE OF PROPERTIES; INTELLECTUAL PROPERTY.  Each
Obligor will maintain, preserve, protect and keep, or cause to be maintained,
preserved, protected and kept its real and personal property used or useful in
the conduct of its business in good working order and condition, reasonable
wear and tear excepted, and will pay and discharge when due the cost of repairs
to and maintenance of the same.

           With respect to any and all trademarks, registrations, copyrights,
patents, patent rights and applications for any of the foregoing, each Obligor
shall maintain and protect the same and shall take and assert any and all
remedies available to that Obligor to prevent any other Person from infringing
upon or claiming any interest in any such trademarks, registrations,
copyrights, patents, patent rights or application for any of the foregoing.

                 7.12  INSURANCE.  Each Obligor will carry adequate insurance
issued by an insurer acceptable to Bank, in amounts acceptable to Bank (at
least adequate to comply with any co-insurance provisions) and against all such
liability and hazards as are usually carried by entities engaged in the same or
a similar business similarly situated or as may be required by Bank.  In the
case of insurance on any of the Collateral, Obligors shall carry insurance in
amounts equal to the full insurable value thereof and cause Bank to be named as
loss payee (with a lender's loss payable endorsement) and additional insured
with respect to all liability insurance, as its interests may appear with
thirty (30) days' notice to be given Bank by the insurance carrier prior to
cancellation or material modification of such insurance coverage.

           Obligors shall cause to be delivered to Bank the insurance policies
therefor and at least three (3) Business Days prior to the expiration of any
such insurance, additional policies or duplicates thereof or in the
alternative, certificates of insurance evidencing the renewal of such insurance
and payment of the premiums therefor.  Obligors shall direct all insurers that
in the event of any loss involving any Collateral or the cancellation of any
insurance policy covering the Collateral, the insurers shall make payments for
such loss and pay all return or unearned premiums directly to Bank and not to
Obligors, or any of them, and Bank jointly.





                                       27
   34
           In the event of any loss involving any Collateral, Obligors will
give Bank immediate notice thereof and Bank may make proof of loss whether the
same is done by Obligors.  Bank is granted a power of attorney by any Obligor
with full power of substitution to file any proof of loss in any Obligor's or
Bank's name, to endorse any Obligor's name on any check, draft or other
instrument evidencing insurance proceeds, and to take any action or sign any
document to pursue any insurance loss claim involving any Collateral.  Such
power being coupled with an interest is irrevocable.

           In the event of any loss involving any Collateral, Bank, at its
option, may (a) retain and apply all or any part of the insurance proceeds to
reduce, in such order and amounts as Bank may elect, the Bank Indebtedness, or
(b) disburse all or any part of such insurance proceeds to or for the benefit
of an Obligor for the purpose of repairing or replacing Collateral after
receiving proof satisfactory to Bank of such repair or replacement, in either
case without waiving or impairing the Bank Indebtedness or any provision of
this Agreement.  Any deficiency thereon shall be paid by Obligors to Bank upon
demand.  Obligors shall not take out any insurance covering the Collateral
without having Bank named as loss payee or additional insured thereon, as
applicable.  Obligors shall bear the full risk of loss from any loss of any
nature whatsoever with respect to the Collateral.

           Notwithstanding the foregoing, in the event that an Obligor suffers
a casualty loss involving any inventory which was Collateral and desires to use
the proceeds of its casualty loss insurance to repair or replace damaged
inventory which was Collateral hereunder, Bank will permit that Obligor to
utilize the proceeds of such insurance solely to purchase such replacement
inventory, provided that:  (i) Obligor confirms to Bank in writing that it
intends to continue its business operations and has business interruption
insurance in effect providing for the payment of proceeds in amounts acceptable
to Bank, (ii) Obligor submits to Bank its business plan for operations after
such casualty loss, which plan must be in form and content satisfactory to
Bank, (iii) Bank will hold such insurance proceeds and will disburse such
proceeds upon receipt by Bank of evidence satisfactory to Bank that such
proceeds will be used to purchase inventory as required above, (iv)
disbursement of proceeds will be in compliance with such procedures as Bank may
require, e.g. checks payable to the inventory supplier, and (v) no Event of
Default or Default has occurred and is continuing.

                 7.13  INSPECTIONS; EXAMINATIONS.  Obligors hereby irrevocably
authorize and direct all accountants and auditors employed by any Obligor at
any time to exhibit and deliver to Bank copies of any and all of Obligors'
financial statements, trial balances or other accounting records of any sort in
the accountant's or auditor's possession and copies of all reports submitted to
Obligors by such accountants or auditors, including management letters,
"comment" letters and audit reports, and to disclose to Bank any information
they may have concerning Obligors' financial status and business operations.
Obligors further authorize all federal, state and municipal authorities to
furnish to Bank copies of reports or examinations relating to Obligor, whether
made by an Obligor or otherwise.

           The officers of Bank, or such Persons as any of them may designate,
may visit and inspect any of the properties of Obligors, examine (either by
Bank's employees or by independent





                                       28
   35
accountants) any of the Collateral or other assets of Obligors, including the
books of account of Obligors, and discuss the affairs, finances and accounts of
Obligors with its officers and with its independent accountants, at such times
as Bank may desire.

           Bank may conduct at any time and from time to time, and Obligors
will fully cooperate with, field examinations of the inventory, accounts
receivable and business affairs of Obligors.  Obligors shall reimburse Bank for
its out-of-pocket costs in connection with such examinations.

                 7.14  DEFAULT UNDER OTHER INDEBTEDNESS.  If any Indebtedness
of any Obligor is declared or becomes due and payable before its expressed
maturity by reason of default or otherwise or, to the knowledge of an Obligor,
the holder of any such Indebtedness shall have the right (or upon the giving of
notice or the passage of time, or both, shall have the right) to declare such
Indebtedness to be so due and payable, Obligors will immediately give Bank
written notice of such declaration, acceleration or right of declaration.

                 7.15  PENSION PLANS.  Obligors will (a) keep in full force and
effect any and all Plans which are presently in existence or may, from time to
time, come into existence under ERISA and will remain a member of each
multi-employer Plan in which any Obligor is a member, unless such Plans can be
terminated or withdrawal from such multi-employer Plan can be accomplished
without material liability to any Obligor in connection with such termination
(as distinguished from any continuing funding obligation); (b) make
contributions to all of Obligors' Plans in a timely manner and in a sufficient
amount to comply with the requirements of ERISA; (c) comply with all material
requirements of ERISA which relate to such Plans so as to preclude the
occurrence of any Reportable Event, Prohibited Transaction or material
"accumulated funding deficiency" as such term is defined in ERISA; and (d)
notify Bank immediately upon receipt by any Obligor of any notice of the
institution of any proceeding or other action which may result in the
termination of any Plan and deliver to Bank, promptly after the filing or
receipt thereof, copies of all reports or notices which any Obligor files or
receives under ERISA with or from the Internal Revenue Service, the PBGC, or
the U.S. Department of Labor.

                 7.16  BANK OF ACCOUNT.  Obligors will maintain Bank as their
major bank of account, unless otherwise agreed by Bank in writing.  Subject to
SECTION 5.5, Obligors may maintain operating accounts into which their accounts
receivable are deposited for ultimate transfer to a deposit account maintained
with the Bank. Obligors may also maintain local operating accounts for
convenience as necessary.  Obligors will notify Bank in writing and on a
continuing basis, of all deposit accounts and certificates of deposit
(including the numbers thereof) maintained with or purchased from any other
financial institutions.

                 7.17  MAINTENANCE OF MANAGEMENT. Obligors will cause their
business to be continuously managed by Vaughn E. Drum and P. Blake Dupuis or
such other persons (serving in such management positions) as may be reasonably
satisfactory to Bank.  Obligors will notify Bank promptly in writing of any
change in their board of directors or executive officers.





                                       29
   36
                 7.18  CAPITAL STOCK.  UTI will not redeem, repurchase or
otherwise make or pay any distribution or dividend upon, or payment or
distribution to acquire, any of its capital stock or other Equity Securities.
Notwithstanding the foregoing, UTI may redeem, acquire or repurchase its Equity
Securities (a) to pay purchase price reductions or in settlement of indemnity
claims required in connection with any acquisition permitted under SECTION 7.7
in which UTI issues its common stock or other Equity Securities as part of the
purchase price, (b) in connection with the terms of UTI's existing employee
benefit plans in the ordinary course of UTI's  business, provided that the
amount expended for such stock purchases related to the benefit plans does not
exceed $1,000,000 in any one fiscal year, (c) in connection with any exercise
of stock options, warrants or other rights to acquire Equity Securities that do
not result in the distribution of cash by UTI other than for fractions of a
unit of any Equity Securities, and (d) in connection with a stock buy-back plan
approved by the Board of Directors of UTI and disclosed to Bank, provided that,
the amount expended for such stock purchases does not exceed Ten Million
Dollars ($10,000,000.00) in the aggregate.

                 7.19  TRANSACTIONS WITH AFFILIATES.  No Obligor will enter
into directly or indirectly any transaction or material group of related
transactions (including without limitation the purchase, lease, sale or
exchange of properties of any kind or the rendering of any service) with any
Affiliate (other than another Obligor) except in the ordinary course and
pursuant to the reasonable requirements of each Obligor's business and upon
fair and reasonable terms no less favorable to such Obligor than would be
obtainable in a comparable arm's-length transaction with a Person not an
Affiliate.

           No Obligor will make any loans or extensions of credit to any of its
Affiliates (that are not Obligors), shareholders, directors or officers, except
as hereinafter expressly provided.  Each Obligor will cause all of its
Indebtedness at any time owed to its Affiliates (that are not Obligors),
shareholders, directors and officers to be subordinated in all respects to all
present and future Bank Indebtedness and will not make any payments thereon,
except as approved by Bank in writing.

           Notwithstanding the foregoing, the restrictions set forth above in
this SECTION 7.19 will not apply to (a) the payment of reasonable and customary
regular fees to directors of UTI who are not employees of UTI; (b) loans and
advances to officers, directors and employees of Obligors for travel,
entertainment and moving and other relocation expenses made in direct
furtherance and in the ordinary course of business of Obligors; (c) any other
transaction with any employee, officer or director of Obligors pursuant to
employee benefit or compensation arrangements entered into in the ordinary
course of business and approved by the Board of Directors of Obligors; or (d)
customary investment banking or similar transactions with an Affiliate,
provided that compensation paid to such Affiliate and related expenses and
reimbursements are in customary amounts as would be determined in arm's-length
negotiations.

           Obligors agree to give Bank prompt notice of each Affiliate
transaction involving cash or other compensation in excess of $500,000 (not
including Equity Securities issued as compensation).





                                       30
   37
           The exceptions permitted under SECTION 7.19 shall be permitted only
provided that (a) no Default or Event of Default has occurred and is
continuing, and (b) any action taken by any Obligor which would constitute a
permitted exception would not cause or result in an Event of Default.

           Nothing in this SECTION 7.19 shall prohibit, limit or restrict the
transactions permitted under SECTIONS 7.3, 7.4, 7.5, 7.6, 7.7, 7.15, 7.18 OR
7.20 hereof.

                 7.20  RESTRICTION ON STOCK TRANSFER.  No Obligor, other than
UTI, will directly or indirectly issue, transfer, sell or otherwise dispose of,
or part with control of, or permit the transfer of, any shares of its capital
stock, except for issuance, transfer, sale or disposition by one Obligor to
another.

                 7.21  NAME OR ADDRESS CHANGE.  No Obligor will change its name
or address except upon thirty (30) days prior written notice to Bank and
delivery to Bank of any items requested by Bank to maintain perfection and
priority of Bank's security interests and access to Obligors' books and
records.

                 7.22  NOTICES.  Obligors will promptly notify Bank of (a) any
action or proceeding brought against any Obligor wherein such action or
proceeding would, if determined adversely to any Obligor result in liability of
any Obligor in excess of One Million Dollars ($1,000,000.00) in the aggregate
with all other actions and proceedings, (b) the occurrence of any Default or
Event of Default, (c) the failure of any Obligor to observe any of its
undertakings under the Loan Documents, or (d) any material adverse change in
the assets, business, operations or financial condition of any Obligor.

                 7.23  ADDITIONAL DOCUMENTS AND FUTURE ACTIONS.   Each Obligor
will, at its sole cost, take such actions and provide Bank from time to time
with such agreements, financing statements and additional instruments,
documents or information as the Bank may in its discretion deem reasonably
necessary or advisable to perfect, protect, maintain or enforce the security
interests in the Collateral, to permit Bank to protect or enforce its interest
in the Collateral, or to carry out the terms of the Loan Documents.  Each
Obligor hereby authorizes and appoints Bank as its attorney-in-fact, with full
power of substitution, to take such actions as Bank may deem advisable to
protect the Collateral and its interests thereon and its rights hereunder, to
execute on that Obligor's behalf and file at that Obligor's expense financing
statements, and amendments thereto, in those public offices deemed necessary or
appropriate by Bank to establish, maintain and protect a continuously perfected
security interest in the Collateral, and to execute on that Obligor's behalf
such other documents and notices as Bank may deem advisable to protect the
Collateral and its interests therein and its rights hereunder.  Such power
being coupled with an interest is irrevocable.  Each Obligor irrevocably
authorizes the filing of a carbon, photographic or other copy of this
Agreement, or of a financing statement, as a financing statement and agrees
that such filing is sufficient as a financing statement.





                                       31
   38
                 7.24  MATERIAL ADVERSE CONTRACTS.   No Obligor will become or
be a party to any contract or agreement which has a materially adverse impact
on that Obligor's ability to perform under this Agreement or any other
agreement with Bank to which that Obligor is a party.

                 7.25  RESTRICTIONS ON USE OF PROCEEDS.   No Obligor will carry
or purchase with the proceeds of the Line any "margin security" within the
meaning of Regulations U, G, T or X of the Board of Governors of the Federal
Reserve System.

                 7.26  SUBORDINATED TERM LOAN.  Obligors will not amend, modify
or restate any of the provisions of the Subordinated Term Loan or any of the
Subordinated Debt Loan Documents, in any way which in Bank's judgment would
adversely affect the Bank Indebtedness, the Collateral, the Subordination
Agreement, any Obligor's business, operations or financial condition, or any
rights or remedies of Bank.  Without limitation, no modification shall be made
which increases the interest rate, fees or other sums payable in connection
with the Subordinated Term Loan or under the Subordinated Debt Loan Documents,
shortens or accelerates the maturity or due date of any payments under the
Subordinated Term Loan, grants any security interest to secure all or any part
of the Subordinated Term Loan, makes any financial covenant or ratio more
restrictive, or results in any situation in which a default could occur under
the Subordinated Term Loan without such event constituting an Event of Default
hereunder.

           The provisions in the Subordination Agreement permitting the
Subordinated Lenders to enter into amendments or modifications of the
Subordinated Debt Loan Documents with respect to interest rate increases and
fees shall not be deemed to be a consent or agreement by Bank to any increase
in the interest rate of the Subordinated Term Loan or any new or increased fees
payable in connection with the Subordinated Term Loan.  Such amendments or
modifications shall still require the consent by Bank.  Obligors will give Bank
a copy of any proposed amendment, modification or restatement of any
Subordinated Debt Loan Document at least ten (10) days prior to the execution
thereof.  Obligors will not enter into any such amendment, modification or
restatement, if Bank has notified Obligors that it would be a violation of this
SECTION 7.26.

           No Obligor will, directly or indirectly, repurchase, redeem, or
defease prior to the date when due or otherwise make any prepayment prior to
the date when due, or effect any prepayment that is optional on the part of
such Obligor, on any Indebtedness for borrowed money (other than the
Subordinated Term Loan) without the prior written consent of Bank, except that
no such consent is required for and UTI may effect (a) any transaction in which
UTI's capital stock is exchanged for Indebtedness owed by any of the Obligors,
including any cashless warrant exercise arrangements in which warrants are
exercised without cash payment by the Person so exercising, or exchange of
indebtedness owed by any of the Obligors for capital stock of UTI, (b)
permitted prepayments under this Agreement, (c) prepayments required or
permitted under the terms of the Subordinated Debt Loan Documents, and (d)
prepayments of Indebtedness owed to Bank in accordance with or required under
this Agreement.  Obligors will give Bank a copy of each notice of default or
other substantive notice received by any Obligors from any Subordinated Lender,
as soon as possible but no later than two (2) Business Days after such
Obligor's receipt.  Obligors will also deliver to Bank a copy of each





                                       32
   39
compliance certificate or other report or certificate delivered by any Obligor
to any Subordinated Lender simultaneously with delivery to such Subordinated
Lender.  Nothing contained in this SECTION 7.26 shall limit, restrict, waive or
adversely affect any of Bank's rights or remedies under the Subordination
Agreement.

           Promptly upon becoming aware of the existence of any default or
event of default under the Subordinated Debt Loan Documents, Obligors will give
Bank written notice specifying the nature  thereof and describing what action
the Obligors are taking or propose to take with respect thereto.

           Notwithstanding anything herein or elsewhere to the contrary, no
Obligor will make any payment on any of the Subordinated Term Loan, if an Event
of Default or Default has occurred and is continuing, or such payment would
result in an Event of Default.

                 7.27  ACQUISITION DOCUMENTS.  Obligors will not amend or
modify any of the documents or agreements executed and delivered in connection
with any prior acquisitions or in connection with any future acquisitions
approved or permitted under SECTION 7.7 in any material way or waive any
material rights thereunder.

could restrict in any material respect the use, occupancy or transferability of
any of the Collateral or any of the facilities owned, leased or operated by any
Environmental Affiliate.

                 10.2  REAL PROPERTY.  Obligors represent and warrant to Bank
that, to the best of Obligors' knowledge, there are no Special Materials
presently located on or, to the best of their knowledge, near any real property

Report will not materially and adversely affect the business, financial
condition or results of operations of the Obligors taken as a whole.

                 10.3  COVENANT REGARDING COMPLIANCE.  Obligors shall take or
cause all Environmental Affiliates to take, at Obligors' and such Environmental
Affiliate's sole expense, such actions as may be necessary to comply in all
material respects with all Environmental Requirements, as hereinafter defined.
If any Environmental Affiliate shall fail to take such action, Bank may make
advances or payments towards performance or satisfaction of the same but shall
be under no obligation to do so.  All sums so advanced or paid, including all

certificates of compliance or disposal from all contractors retained in
connection with such activities.

                 10.4  NOTICES.  In the event Obligors become aware of any
past, present or future facts or circumstances which have given rise or could
give rise to a claim against any Environmental Affiliate related to a failure
to comply with any Environmental Requirements, Obligors will promptly give Bank
notice thereof, together with a written statement of an officer of Obligors
setting forth the details thereof and the action with respect thereto taken or
proposed to be taken by the Environmental Affiliates.

                 10.5  INDEMNITY.  Obligors agree to indemnify, defend and hold
harmless Bank, its parents, subsidiaries, successors and assigns, and any
officer, director, shareholder, employee, Affiliate or agent of Bank, for all
loss, liability, damage, cost and expenses, including, without limitation,

visit, inspect, examine and test all properties owned, leased or operated by
and all products and wastes generated, treated, stored, transported, handled or
disposed of by or on behalf of any Environmental Affiliate, for the purpose of
investigating compliance with Environmental Requirements, any actual or
potential claims related thereto, and any condition which could result in
potential liability, cost or expenses to the Bank.  Obligors will permit, and
will cause all Environmental Affiliates to permit, such Environmental
Consultants to have access to all of such properties, products and wastes and
all books, records and reports related to compliance by the Environmental
Affiliates with all Environmental Requirements.  Obligors will supply, and will

Environmental Affiliates having knowledge of such matters.

           The cost of such visits, inspections, examination and tests shall be
borne by the Obligors.  In the event Bank pays such costs, such sums shall be
at once repayable by Obligors and all sums so advanced or paid by Bank shall
become part of the Bank Indebtedness.  Notwithstanding the foregoing, the Bank
shall have no obligation to perform any tests, examinations or inspections or
to monitor the Environmental Affiliates' compliance with all Environmental
Requirements.

                 13.2  REMEDIES.  At the option of the Bank, upon the

                                       44
   51
                 13.3  SALE OR OTHER DISPOSITION OF COLLATERAL.  The sale,
lease or other disposition of the Collateral, or any part thereof, by Bank
after an Event of Default may be for cash, credit or any combination thereof,
and Bank may purchase all or any part of the Collateral at public or, if
permitted by law, private sale, and in lieu of actual payment of such purchase
price, may set-off the amount of such purchase price against the Bank
Indebtedness then owing.  Any sales of the Collateral may be adjourned from
time to time with or without notice.  Bank may cause the Collateral to remain
on any Obligor's premises or otherwise or to be removed and stored at premises
owned by other persons, at Obligors' expense, pending sale or other disposition
of the Collateral.  Obligors, at Bank's request, shall assemble the Collateral
consisting of inventory and tangible assets and make such assets available to
Bank at a place to be designated by Bank.  Bank shall have the right to conduct
such sales on any Obligor's premises, at any Obligor's expense, or elsewhere,
on such occasion or occasions as Bank may see fit.  Any notice required to be
given by Bank of a sale, lease or other disposition or other intended action by
Bank with respect to any of the Collateral which is deposited in the United
States mail, postage prepaid and duly addressed to Obligors at the address
specified in SECTION 14 below, at least five (5) Business Days prior to such
proposed action, shall constitute fair and reasonable notice to Obligors of any
such action.  The net proceeds realized by Bank upon any such sale or other
disposition, after deduction for the expenses of retaking, holding, storing,
transporting, preparing for sale, selling or otherwise disposing of the
Collateral incurred by Bank in connection therewith and all other costs and
expenses related thereto including attorney fees, shall be applied in such
order as Bank, in its sole discretion, elects, toward satisfaction of the Bank
Indebtedness.  Bank shall account to Obligors for any surplus realized upon
such sale or other disposition, and Obligors shall remain liable for any
deficiency.  The commencement of any action, legal or equitable, or the
rendering of any judgment or decree for any deficiency shall not affect Bank's
security interest in the Collateral.  Obligors agree that Bank has no
obligation to preserve rights to the Collateral against any other parties.
Bank is hereby granted a license or other right to use, after an Event of
Default, without charge, any Obligor's labels, general intangibles,
intellectual property, equipment, real estate, patents, copyrights, rights of
use of any name, trade secrets, trade names, trademarks, service marks and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale and selling any
inventory or other Collateral and Obligors' rights under all contracts,
licenses, approvals, permits, leases and franchise agreements shall inure to
Bank's benefit.  Bank shall be under no obligation to marshall any assets in
favor of any Obligor or any other party or against or in payment of any or all
of the Bank Indebtedness.

                 13.4  ACTIONS WITH RESPECT TO ACCOUNTS.  Each Obligor hereby
irrevocably makes, constitutes and appoints Bank (and any of Bank's designated
officers, employees or agents) as its true and lawful attorney-in-fact, with
full power of substitution, with power to sign its name and to take any of the
following actions, in its name or the name of Bank, as Bank may determine,
without notice to any Obligor and at Obligors' expense:

                       (a)   Verify the validity and amount of or any other
matter relating to the Collateral by mail, telephone, telecopy or otherwise;





                                       45
   52

                       (f)   Upon the occurrence of an Event of Default, have
access to any lockbox or postal boxes into which any Obligor's mail is
deposited and receive, open and dispose of all mail addressed to any Obligor
(any sums received pursuant to the exercise of the rights provided in SECTIONS
13.4(A) through (E) above may, at Bank's option, be deposited in a cash
collateral account);

                       (g)   Upon the occurrence of an Event of Default, take
control in any manner of any rejected, returned, stopped in transit or
repossessed goods relating to any accounts;

                       (h)   Upon the occurrence of an Event of Default,
enforce payment of and collect any accounts, by legal proceedings or otherwise,
and for such purpose Bank may:

                             (i)   Demand payment of any accounts or direct any
account debtors to make payment of accounts directly to Bank;

                             (ii)  Receive and collect all monies due or to
become due to any Obligor;

                             (iii) Exercise all of any Obligor's rights and
remedies with respect to the collection of accounts;

                             (iv)  Settle, adjust, compromise, extend, renew,

for such amount and at such times as Bank deems advisable;





                                       46
   53
                             (vi)  Prepare, file and sign any Obligor's name or
names on any Proof of Claim or similar document in any proceeding filed under
federal or state bankruptcy, insolvency, reorganization or other similar law as
to any account debtor;

                             (vii) Prepare, file and sign any Obligor's name or
names on any Notice of Lien, Claim of Mechanic's Lien, Assignment or

interest that may come into Bank's possession;

                             (ix)  Sign the name of each Obligor to
verifications of accounts and notices thereof sent by account debtors to such
Obligor; or

                             (x)   Take all other actions necessary or
desirable to protect any Borrower's or Bank's interest in the accounts.

Obligors ratify and approve all acts of said attorneys and agree that said
attorneys shall not be liable for any acts of commission or omission, nor for
any error of judgment or mistake of fact or law, except gross negligence or
willful misconduct.  This power, being coupled with an interest, is
irrevocable.  Obligors agree to assist the Bank in the collection and
enforcement of Obligors' accounts and not to hinder, delay or impede the Bank
in its collection or enforcement of said accounts.

                 13.5  SET-OFF.  Without limiting the rights of Bank under
applicable law, Bank has and may exercise a right of set-off, a lien against
and a security interest in all property of any Obligor now or at any time in
Bank's possession in any capacity whatsoever, including but not limited to any
balance of any deposit, trust or agency account, or any other bank account with
Bank, as security for all Bank Indebtedness.  At any time and from time to time
following the occurrence of an Event of Default or any Default, Bank may
without notice or demand, 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 Bank to or for the credit of any Obligor
against any or all of the Bank Indebtedness and each Obligor's obligations
under the Loan Documents.  Bank shall use its best efforts to provide to the
Obligors prompt written notice of the exercise of any set-off rights, provided
that the failure of Bank to provide such notice shall not limit or affect the
validity or effectiveness of such set-off.

                 13.6  TURNOVER OF PROPERTY HELD BY BANK.   Each Obligor
irrevocably authorizes any Affiliate of Bank, upon and following the occurrence
of an Event of Default, at the request of Bank and without further notice, to
turnover to Bank any property of any Obligor held by such Affiliate, including
without limitation, funds and securities for any Obligor's account and to





                                       47
   54
debit, for the benefit of Bank, any deposit account maintained by any Obligor
with such Affiliate (even if such deposit account is not then due or there
results a loss or reduction of interest or the imposition of a penalty in
accordance with law applicable to the early withdrawal of time deposits), in
the amount requested by Bank up to the amount of the Bank Indebtedness, and to
pay or transfer such amount or property to Bank for application to the Bank
Indebtedness.

                 13.7  DELAY OR OMISSION NOT WAIVER.  Neither the failure nor
any delay on the part of Bank to exercise any right, remedy, power or privilege
under the Loan Documents upon the occurrence of any Event of Default or
otherwise shall operate as a waiver thereof or impair any such right, remedy,
power or privilege.  No waiver of any Event of Default shall affect any later
Event of Default or shall impair any rights of Bank.  No single, partial or
full exercise of any rights, remedies, powers and privileges by the Bank shall
preclude further or other exercise thereof.  No course of dealing between Bank
and Obligors shall operate as or be deemed to constitute a waiver of Bank's
rights under the Loan Documents or affect the duties or obligations of
Obligors.

                 13.8  REMEDIES CUMULATIVE; CONSENTS.  The rights, remedies,
powers and privileges provided for herein shall not be deemed exclusive, but
shall be cumulative and shall be in addition to all other rights, remedies,
powers and privileges in Bank's favor at law or in equity.  Whenever the Bank's
consent or approval is required or permitted, such consent or approval shall be
at the sole and absolute discretion of Bank.

                 13.9  CERTAIN FEES, COSTS, EXPENSE EXPENDITURES AND
INDEMNIFICATION.  Each Obligor agrees to pay on demand all costs and expenses
of Bank, consisting of:

                       (a)   all costs and expenses in connection with (i) the
preparation, review, negotiation, execution, delivery and administration of the
Loan Documents, and the other documents to be delivered in connection
therewith, or any waivers, consents, amendments, extensions and increases to
any of the foregoing, (ii) the preparation for, negotiations regarding,
consultations concerning, or the defense or prosecution of legal proceedings
involving any claims made or threatened against Bank arising out of or related
to the Loan Documents, the transactions contemplated hereunder as to the
protection of any of the Collateral, or (iii) obtaining any appraisals or
reappraisals of Collateral, periodic lien searches and tax clearance
certificates, as Bank in its discretion deems necessary (including in all
cases, without limitation, reasonable attorney's fees and expenses);

                       (b)   all losses, costs and expenses in connection with
the interpretation, enforcement, protection and preservation of the Bank's
rights or remedies under the Loan Documents, or any other agreement relating to
any Bank Indebtedness, or in connection with legal advice relating to the
rights or responsibilities of Bank (including without limitation court costs,
reasonable attorney's fees, reasonable expenses of accountants and appraisers
and the cost of all appeals); and





                                       48
   55
                       (c)   any and all stamp and other taxes payable or
determined to be payable in connection with the execution and delivery of the
Loan Documents, and all liabilities to which Bank may become subject as the
result of delay in paying or omission to pay such taxes.

           In the event any Obligor shall fail to pay taxes, insurance,
assessments, costs or expenses which it is required to pay hereunder, or fails
to keep the Collateral free from security interests or lien (except as
expressly permitted herein), or fails to maintain or repair the Collateral as
required hereby, or otherwise breaches any obligations under the Loan
Documents, Bank in its discretion, may make expenditures for such purposes and
the amount so expended (including attorney's fees and expenses, filing fees and
other charges) shall be payable by Obligors on demand and shall constitute part
of the Bank Indebtedness.

           With respect to any amount required to be paid by Obligors under
this Section, in the event Obligors fail to pay such amount on demand, Obligors
shall also pay to Bank interest thereon at the Default Rate.

           Obligors agree to indemnify and hold harmless, Bank and Bank's
officers, directors, shareholders, employees and agents, from and against any
and all claims, liabilities, losses, damages, costs and expenses (whether or
not such Person is a party to any litigation), including attorney's fees and
costs and costs of investigation, document production, attendance at
depositions or other discovery with respect to or arising out of this
Agreement, the use of any proceeds advanced hereunder, the transactions
contemplated hereunder, or any claim, demand, action or cause of action being
asserted against any Obligor or any of its Affiliates.

           Obligors' obligations under this Section shall survive termination
of this Agreement and repayment of the Bank Indebtedness.

                 13.10 TIME IS OF THE ESSENCE.  Time is of the essence in
Obligors' performance of their obligations under the Loan Documents.

                 13.11 INDEMNIFICATION.  Obligors, jointly and severally shall
indemnify, defend and hold Bank, and its directors, agents, employees and
counsel, harmless from and against any and all losses, claims, damages,
liabilities, deficiencies, judgments, penalties, costs or expenses imposed on,
incurred by or asserted against any of them in connection with any litigation,
investigation, claim or proceeding commenced or threatened related to the
negotiation, preparation, execution, delivery, enforcement, performance or
administration of this Agreement, any other Loan Documents, or any undertaking
or proceeding related to any of the transactions contemplated hereby or any
act, omission to act, event or transaction related or attendant thereto and
including, without limitation, amounts paid in settlement, court costs, and the
fees and expenses of counsel, except that Obligors shall not be required to
indemnify, defend or hold harmless Bank from or against any such loss, claim,
damage, liability, deficiency, judgment, penalty or cost to the extent that the
undertaking to indemnify, pay and hold harmless set forth in this section may
be unenforceable because it violates any law or public policy, or results from
Bank's gross negligence or wilful misconduct.  Obligors shall





                                       49
   56
pay the maximum portion which it is permitted to pay under applicable law to
Bank in satisfaction of indemnified matters under this Section.  The foregoing
indemnity shall survive the payment of the Bank Indebtedness and the
termination or non-renewal of this Agreement.

           14.   COMMUNICATIONS AND NOTICES.  All notices, requests and other
