AMENDED AND RESTATED CREDIT AGREEMENT

THIS AMENDED AND RESTATED CREDIT AGREEMENT dated as of July
18, 1997 is among CORE LABORATORIES N.V., a Netherlands limited liability
company (the "Parent"), CORE LABORATORIES, INC., a Delaware corporation (the
"US Borrower"), CORE LABORATORIES (U.K.) LIMITED, a company organized under the
laws of England and Wales (the "UK Borrower" and, together with the Parent and
the US Borrower, the "Borrowers"), the banks named on the signature pages
hereto (together with their respective successors and assigns in such capacity,
the "Banks"), BANKERS TRUST COMPANY, as a Guilder Swing Line Bank and the
administrative agent for the Banks (together with its successors and assigns in
such capacity, the "Administrative Agent") and NATIONSBANK, N.A., as a Guilder
Swing Line Bank and the syndication agent for the Banks (together with its
successors and assigns in such capacity, the "Syndication Agent" and, together
with the Administrative Agent, the "Agents"), as the issuing bank with respect
to the Letters of Credit issued hereunder (together with its successors and
assigns in such capacity, the "Issuing Bank"). Unless otherwise defined herein,
all capitalized terms used herein and defined in Article I are used herein as
so defined.

PRELIMINARY STATEMENT

The Parent, the US Borrower, the UK Borrower, the
Administrative Agent, the Syndication Agent, and each of two said Agents, as
existing Banks, previously entered into a Credit Agreement dated May 12, 1997
(the "Prior Credit Agreement") relating to the extension of various Loans to
the Borrowers by said existing Banks. The Borrowers have now requested that
certain of said Loans be modified and amended from the structure described in
the Prior Credit Agreement and additional Persons have agreed to become Banks
hereunder. Specifically, the Borrowers have requested that the Banks refinance
the Loans of the Prior Credit Agreement by providing (a) the Parent with a
$55,000,000 term loan facility and the Equivalent in Dutch Guilders of a
$5,000,000 revolving credit facility, (b) the US Borrower with a $50,000,000
revolving credit facility providing for letters of credit and revolving loans,
and (c) the UK Borrower with the Equivalent in Pounds Sterling of a $15,000,000
term loan facility, each of which will be used to refinance and rearrange the
Indebtedness existing under the Prior Credit Agreement and otherwise as
specified herein. The Parent has also requested that the Guilder Swing Line
Banks provide it with the Equivalent in Dutch Guilders of a $5,000,000
revolving credit facility in the form of a Guilder Swing Line Loan, which will,
initially, substitute for the $5,000,000 Dutch Guilder revolving credit
facility. The Banks and the Guilder Swing Line Banks have agreed to provide
the Borrowers with such credit facilities upon the terms and conditions set
forth in this Agreement which will constitute an amendment and restatement, but
not a novation, of the Prior Credit Agreement.

Accordingly, in consideration of the foregoing and the mutual
covenants set forth herein, the parties agree as follows:
7
ARTICLE I
DEFINITIONS, TERMS AND INTERPRETATION

Section 1.01 Certain Defined Terms. Capitalized terms used
in this Agreement and not otherwise defined herein, shall have the respective
meanings set forth in Annex A (such meanings to be equally applicable to both
singular and plural forms of the terms defined).

Section 1.02 Accounting Terms. All accounting terms not
specifically defined herein shall be construed, and all financial calculations
shall be made, in accordance with GAAP consistent with those applied in the
preparation of the consolidated financial statements referred to in Section
4.06, provided, if any accounting changes made by any Borrower that are allowed
or required by GAAP result in the calculations that are utilized to compute the
compliance with Section 6.04 being inconsistent with such prior calculations,
the affected Borrower agrees to negotiate in good faith with the Administrative
Agent and the Syndication Agent to re-establish appropriate, meaningful ratios
and covenants.

Section 1.03 Computation of Time Periods. In this Agreement
in the computation of periods of time from a specified date to a later
specified date, the word "from" means "from and including" and the words "to"
and "until" each means "to but excluding."

Section 1.04 References. The words "hereof," "herein" and
"hereunder" and words of similar import when used in this Agreement or any
Annex or Exhibit attached hereto shall refer to this Agreement as a whole and
not to any particular provision of this Agreement. All references herein to
Articles, Sections, Annexes, Exhibits and Schedules shall, unless the context
requires a different construction, be deemed to be references to the Articles
and Sections of this Agreement and the Annexes, Exhibits and Schedules attached
hereto and made a part hereof. In this Agreement, unless a clear contrary
intention appears, the word "including" (and with correlative meaning
"include") means including, without limiting the generality of any description
preceding such term. No provision of this Agreement shall be interpreted or
construed against any Person solely because that Person or its legal
representative drafted such provision.

ARTICLE II

term loan to the Parent (a "Tranche A Loan") on or promptly after the Effective

term loan to the UK Borrower (a "Tranche B Loan") on or promptly after the
Effective Date in an amount not to exceed the Equivalent in Pounds Sterling of
such Bank's Tranche B Commitment as of the Date of Determination. Each Tranche
B Loan shall be made as a Eurocurrency Rate Loan made by the Banks ratably
according to their respective Commitment Percentages (it being recognized that
Banque Paribas will not participate in the Tranche B Loan and Bankers Trust

2.13(a), funding and maintenance of the Tranche B Loans shall be in Pounds

any Business Day during the period from the Effective Date up to, but
excluding, the Termination Date in an aggregate amount outstanding for such
Bank not to exceed at any time an amount equal to such Bank's Dollar Revolving
Commitment. Each Dollar Revolving Loan shall be made as either a Base Rate
Loan or a Eurocurrency Rate Loan and as part of a single Borrowing made on the
same day by the Banks ratably according to their respective Commitment
Percentages. Each Base Rate Borrowing of Dollar Revolving Loans shall be in an
aggregate amount not less than $1,000,000, and in integral multiples of
$200,000 in excess thereof or, if less, the entire unfunded portion of the
Total Dollar Revolving Commitment. Each Eurocurrency Rate Borrowing of Dollar
Revolving Loans shall be in an aggregate amount not less than $1,000,000, and
in an integral multiple of $200,000 in excess thereof. Within the limits set
forth above and subject to the terms and conditions of this Agreement, the US
Borrower may borrow, repay pursuant to Section 2.06 or prepay pursuant to
Section 2.08 and reborrow under this Section 2.01(c). All funding and
maintenance of the Dollar Revolving Loans shall be in Dollars.

(ii) The Issuing Bank agrees, on the terms and conditions
hereinafter set forth, to issue standby or commercial letters of
credit for the account of the US Borrower, on behalf of it or any of
its Affiliates and for the benefit of any obligee of payment
obligations of the US Borrower or any of its Affiliates (the "Letters
of Credit") from time to time on any Business Day during the period
from the Effective Date up to, but excluding, the Termination Date in
an aggregate amount for all Outstanding Letters of Credit not
exceeding at any time the Letter of Credit Sublimit. Subject to
Section 2.01(c)(iii), a Letter of Credit shall be denominated in any
currency requested by the US Borrower and agreeable to the Issuing
Bank, shall expire no later than the date set forth in Section
2.03(a), and shall be in such form as approved from time to time by
the Issuing Bank and the US Borrower. Each Bank severally agrees, on
the terms and conditions hereinafter set forth, to purchase
participations in the Letters of Credit issued by the Issuing Bank
pursuant to this Agreement in an amount equal to such Bank's
Commitment Percentage in respect of the Total Dollar Revolving
Commitment of the face amount of such Letter of Credit. Upon the
issuance of each Letter of Credit and as of the Effective Date with
respect to the Existing Letters of Credit, the Issuing Bank shall be
deemed, without further action by any party

-3-
9
hereto, to have sold to each Bank, and each Bank shall be deemed,
without further action by any party hereto, to have purchased from the
Issuing Bank, a participation, to the extent of such Bank's Commitment
Percentage in respect of the Total Dollar Revolving Commitment, in
such Letter of Credit and the Existing Letters of Credit, the
obligations of the Issuing Bank thereunder and in the reimbursement
obligations of the US Borrower due in respect of drawings made under
such Letter of Credit or the Existing Letters of Credit. The Banks
will execute any other documents the Issuing Bank may reasonably
request to evidence the purchase of such participation. On each day
during the period commencing with the issuance by the Issuing Bank of
any Letter of Credit and as of the Effective Date with respect to the
Existing Letters of Credit and ending on the date when such Letter of
Credit or Existing Letters of Credit shall have expired or been
terminated, and, irrespective of whether such Letter of Credit or
Existing Letters of Credit have expired or terminated if such Letter
of Credit or Existing Letters of Credit have been drawn upon and the
amount so drawn has not been reimbursed to the Issuing Bank, the
Dollar Revolving Commitment of each Bank shall be deemed to be
utilized for all purposes hereof in an amount equal to such Bank's
Commitment Percentage in respect of the Total Dollar Revolving
Commitment of the Outstanding Letters of Credit.

(iii) In regard to any Letter of Credit issued in a
currency other than Dollars, the following shall apply: (w) the
Issuing Bank, on the first day of each month (and on any other date
selected by it) shall determine the Dollar Equivalent of all such
Letters of Credit and shall advise the Administrative Agent and each
Bank thereof; (x) any presentation thereof resulting in payments by
the Issuing Bank thereunder shall be repaid to said Issuing Bank, at
the option of the US Borrower, in the currency in which said payments
were made by the Issuing Bank or in Dollars, (y) if the US Borrower
tenders Dollars for the Reimbursement Amount, then, unless such tender
results in the actual receipt by the Issuing Bank (acting reasonably
and in good faith in converting such Dollars into the currency in
which said payments were made by the Issuing Bank) of the
Reimbursement Amount, the US Borrower shall also promptly pay to the
Issuing Bank an additional amount in Dollars as may be necessary to
compensate and indemnify the Issuing Bank for such shortfall (and if,
for any reason, the amount in Dollars so received exceeds the
Reimbursement Amount, the Issuing Bank will refund such excess), and
(z) all calculations required by Section 2.01(c)(iv) shall be made,
calculating the Dollar Equivalent of such non-Dollar Outstanding
Letters of Credit as of the date of issuance of such Letter of Credit
and the date of any payment in response to a drawing thereunder.

(iv) Notwithstanding any other term or provision hereof
(A) no Dollar Revolving Loan shall be made and no Letter of Credit
shall be issued if after giving effect thereto the aggregate amount of
the Dollar Revolving Credit Outstanding (not including Letters of
Credit issued under Section 6.01(g)) would exceed the Total Dollar
Revolving Commitment; and (B) no Letter of Credit shall be issued if,
after giving effect thereto the aggregate amount of Outstanding
Letters of Credit would exceed the Letter of Credit Sublimit.

(d) Guilder Revolving Loans. Each Bank severally agrees,
on the terms and conditions hereinafter set forth, to make one or more loans
(each a "Guilder Revolving Loan") to the Parent from time to time on any
Business Day, during the period from the Effective Date up to but excluding the
Termination Date, in an aggregate amount outstanding for such Bank not to
exceed at any time such Bank's Guilder Revolving Commitment, but only to the
extent that the Guilder Swing Line Banks request that the Banks make Guilder
Revolving Loans as provided in Sections 2.01(e)(ii) and 2.01(e)(iii). The
Parent may not request advances under the Guilder Revolving Loan. Each Guilder
Revolving Loan shall be made as a Base Rate Loan and as part of a single
Borrowing made on the same day by the Banks ratably according to their
respective Commitment Percentages. All Guilder Revolving Loans shall be funded
in Dollars.

(e) Guilder Swing Line Loans. (i) Subject to the terms
and conditions hereof, and in substitution for the Guilder Revolving Loans
described in Section 2.01(d) above, the Guilder Swing Line Banks agree at any
time and from time to time on and after the Effective Date and prior to the
Termination Date, to make swing line loans (each a "Guilder Swing Line Loan"
and collectively, the "Guilder Swing Line Loans") to the Parent in an aggregate
principal amount at any one time outstanding not to exceed the Equivalent in
Dutch Guilders of $5,000,000.00. The Guilder Swing Line Loans shall be made
and maintained as Eurocurrency Rate Loans and as part of a single Borrowing
made by the Guilder Swing Line Banks on the same day ratably according to their
respective Commitment Percentages for Guilder Swing Line Loans. Each Borrowing
of Guilder Swing Line Loans shall be in an aggregate amount not less than the
Equivalent in Dutch Guilders of $800,000 as of the Date of Determination and in
an integral multiple of the Equivalent in Dutch Guilders of $200,000 in excess
thereof. Within the limits set forth above and subject to the terms and
conditions of this Agreement, the Parent may borrow, repay pursuant to Section
2.06 or prepay pursuant to Section 2.08 and reborrow under this Section
2.01(e). Subject to Section 2.13(a) funding and maintenance of Guilder Swing
Line Loans shall be in Dutch Guilders. Guilder Swing Line Loans shall
constitute "Guilder Revolving Loans" for all purposes hereunder, provided, they
shall be held by the Guilder Swing Line Banks (subject to sub-clauses (ii) and
(iii) below), and provided further, the Guilder Swing Line Loans shall not be
considered a utilization of the Guilder Revolving Commitment for the purpose of
calculating the Commitment Fee only.

(ii) At any time after a Default or an Event of Default,
if 100% of the Guilder Swing Line Banks so decide, in their sole
discretion, they may give notice to the Agent to require each Bank to
make a Guilder Revolving Loan in an amount equal to such Bank's
Commitment Percentage times the outstanding principal balance of all
Guilder Swing Line Loans (the "Refunded Guilder Swing Line Loan")
outstanding on the date such notice is given; provided that the
provision of this subsection shall not affect the obligation of the
Parent to prepay Swing Line Loans in accordance with Section 2.06(e).
Upon (A) the delivery of such notice and (B) each Bank either making a
Guilder Revolving Loan or purchasing from the Guilder Swing Line Banks
a pro rata participation in such Guilder Swing Line Loan as required
under Section 2.01(e)(iii), the Guilder Swing Line Commitments and the
Guilder Revolving Loan Commitments shall be terminated. Unless the
Guilder Revolving Commitments shall have expired or terminated, each
Bank shall make

-5-
11
the proceeds of its Guilder Revolving Loan available to the Agent for
the pro rata account of the Guilder Swing Line Banks on the next
Business Day following such request, in immediately available funds.
The proceeds of such Guilder Revolving Loans shall be immediately
applied to repay the Refunded Guilder Swing Line Loan.

(iii) At any time after a Default or an Event of Default,
if the Guilder Revolving Commitments shall have expired or be
terminated while any Guilder Swing Line Loan is outstanding, the
Banks, shall, notwithstanding the expiration or termination of the
Guilder Revolving Commitments, make a Guilder Revolving Loan (which
shall be deemed a "Revolving Credit Loan" for all purposes of this
Agreement and the other Loan Documents) and, if any Bank shall not
have made its Guilder Revolving Loans, such Bank shall be deemed,
without further action by any Person, to have purchased from the
Guilder Swing Line Banks a pro rata participation in such Guilder
Swing Line Loan in either case in an amount equal to such Bank's
Commitment Percentage times the outstanding principal balance of such
Guilder Swing Line Loan. The Agent shall notify each such Bank of the
amount of such Guilder Revolving Loan or participation and such Bank
will transfer to the Agent for the pro rata account of the Guilder
Swing Line Banks on the next Business Day following such notice, in
immediately available funds, the amount of its Guilder Revolving Loan
or participation.

(iv) If any such Bank shall not have so made its Guilder
Revolving Loans or its percentage participation available to the Agent
pursuant to this Section 2.01(e), such Bank agrees to pay interest
thereon for each day from such date until the date such amount is paid
at the lesser of (1) the Federal Funds Rate on the date payment is to
be made to the Agent and (2) the Highest Lawful Rate. Whenever, at
any time after the Agent has received from any Bank such Bank's
Guilder Revolving Loan or participating interest in a Guilder Swing
Line Loan, the Agent receives any payment on account thereof, the
Agent will pay to such Bank its participating interest in such amount
(appropriately adjusted, in the case of interest payments, to reflect
the period of time during which such Bank's participating interest was
outstanding and funded) which payment shall be subject to repayment by
such Bank if such payment received by the Agent is required to be
returned. Each Bank's obligation to make the Guilder Revolving Loans
or purchase such participating interests pursuant to this Section
2.01(e) shall be absolute and unconditional and shall not be affected
by any circumstance, including, without limitation, (A) any set-off,
counterclaim, recoupment, defense or other right which such Bank or
any other Person may have against the Guilder Swing Line Banks or
either one of same, the Agent or any other Person for any reason
whatsoever; (B) the occurrence or continuance of a Default or an Event
of Default or the termination of Guilder Revolving Commitments; (C)
the occurrence of any Material Adverse Effect; (D) any breach of this
Agreement by any of the Borrowers or any other Bank; or (E) any other
circumstance, happening or event whatsoever, whether or not similar to
any of the foregoing. Each Guilder Swing Line Loan, once so
participated by any Bank, shall cease to be a Guilder Swing Line Loan
with respect to that amount for purposes of this Agreement, but shall
continue to be a Guilder Revolving Loan and be evidenced by such
Bank's Guilder Revolving Note.

-6-
12
(v) In the event that any Guilder Swing Line Bank incurs
any tax, cost or expense of the type described in Sections 2.11
through 2.14, inclusive, by reason of repaying or participating a
Guilder Swing Line Loan as described in this Section 2.01(e), the
Parent shall reimburse the Guilder Swing Line Banks the full amount of
such tax, cost or expense subject to the terms and conditions herein.

(vi) The Parent expressly agrees and acknowledges that, in
respect of each Bank's funded participation interest in any Guilder
Swing Line Loan, such Bank shall be deemed to be in privity of
contract with the Parent and have the same rights and remedies against
the Parent under the Loan Documents as if such funded participation
interest in such Guilder Swing Line Loan were a Guilder Revolving
Loan.

(f) All Existing Letters of Credit, whether or not issued
by the Issuing Bank, shall be deemed to be Letters of Credit hereunder. Upon
the expiration of any Existing Letter of Credit, same shall be reissued only by
the Issuing Bank (or may be issued or reissued by another financial institution
in accordance with Section 6.01(g)) in accordance with the provisions of this
Agreement.

(g) Loans of more than one Type and, in the case of
Revolving Loans, in more than one currency, may be outstanding at the same
time, but the Borrowers shall not be entitled to request any Borrowing or to
Convert Loans comprising any Borrowing into Loans of another Type, if after
giving effect to such Borrowing or Conversion, as the case may be, any Bank
would have outstanding at any one time more than (i) two (2) different Types of
Tranche A Loans, (ii) two (2) different Types of Tranche B Loans, (iii) six (6)
different Types of Dollar Revolving Loans, and (iv) two (2) different Types of
Guilder Swing Line Loans or Guilder Revolving Loans.

Section 2.02 Borrowing Procedures; Conversions. (a) Each
Borrowing shall be made upon the written, telecopied or facsimile transmitted
request of the relevant Borrower, given to the Administrative Agent not later
than 11:00 a.m. (New York time) on (i) the third Business Day prior to the
proposed Borrowing Date in the case of a Eurocurrency Rate Borrowing
denominated in Dollars or Pounds Sterling, (ii) the fourth Business Day prior
to the proposed Borrowing Date in the case of a Eurocurrency Rate Borrowing
denominated in Dutch Guilders, or (iii) the Business Day prior to the proposed
Borrowing Date in the case of a Base Rate Borrowing. The Administrative Agent
shall give each other member of the Bank Group prompt notice of such request by
telecopier, telex or cable. Each request for a Borrowing (a "Borrowing
Request") shall specify therein (A) the Borrowing Date for such Borrowing, (B)
the requested Type of Loans comprising such Borrowing, (C) the aggregate amount
of such Borrowing, (D) in the case of a Eurocurrency Rate Borrowing, the
Interest Period for the Loans comprising such Borrowing and (E) in the case of
a Revolving Loan, whether such Revolving Loan is to be a Dollar Revolving Loan
or a Guilder Swing Line Loan. Each Borrowing Request shall be substantially in
the form of Exhibit 2.02(a). Each Bank or Guilder Swing Line Bank, as the case
may be shall, before 12:00 Noon (New York time) on the date of such Borrowing,
make available for the account of its Applicable Lending Office to the
Administrative Agent at the applicable Agent Account in same day funds, such
Bank's Commitment Percentage of such Borrowing. After the Administrative
Agent's receipt of such funds and upon fulfillment of the

-7-
13
applicable conditions set forth in Article III, the Administrative Agent will,
not later than 3:00 p.m. (New York time) on the date of such Borrowing, make
such funds available to the relevant Borrower at the applicable Borrower
Account as is reasonably acceptable to the Administrative Agent and as such
Borrower shall have specified in the related Borrowing Request. Each Borrowing
Request shall be irrevocable and binding on the Borrower delivering the same.

(b) Unless the Administrative Agent shall have received
notice from a Bank prior to the date of any Borrowing that such Bank will not
make available to the Administrative Agent such Bank's Commitment Percentage of
such Borrowing, the Administrative Agent may assume that such Bank has made
such portion available to the Administrative Agent on the date of such
Borrowing in accordance with subsection (a) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower requesting such Borrowing on such date a corresponding amount. If
and to the extent that such Bank shall not have so made its Commitment
Percentage of such Borrowing available to the Administrative Agent, such Bank
and the Borrower requesting such Borrowing severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount, together
with interest thereon for each day from the date such amount is made available
to such Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of such Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such Bank,
the Federal Funds Rate. If such Bank shall repay to the Administrative Agent
such corresponding amount, such amount so repaid shall constitute such Bank's
Loan as part of such Borrowing for purposes of this Agreement, and such
Borrower shall be relieved of the obligation to repay such amount under this
Section 2.02(b). The failure of any Bank to make the Loan to be made by it as
part of any Borrowing shall not relieve any other Bank of its obligation, if
any, hereunder to make its Loan on the date of such Borrowing or any subsequent
Borrowing Date, but no Bank shall be responsible for the failure of any other
Bank to make the Loan to be made by such other Bank on the date of any
Borrowing.

(c) Each Borrower may, subject to the terms of this
Agreement, upon written, telecopied or facsimile transmitted notice (a
"Conversion Notice") to the Administrative Agent, given not later than the
times specified below on any Business Day on which no Default or Event of
Default has occurred and is continuing, Convert all Loans comprising one or
more Borrowings from its credit facility hereunder into one or more Borrowings
comprised of Loans from the same credit facility so long as, after giving
effect to any such Conversion, each Borrowing resulting from such Conversion is
comprised of Loans denominated in the same currency and, in the case of each
Borrowing comprised of Eurocurrency Rate Loans, having not more than two (2)
separate Interest Periods for each such Loan. The Administrative Agent shall
promptly transmit the contents of such Conversion Notice to each other member
of the Bank Group by telecopier, telex or cable. Notwithstanding any other term
or provision hereof, after giving effect to any such Conversion, the size of
all Borrowings outstanding hereunder, and the number of different Types of
Loans outstanding hereunder, shall conform to the requirements of Section 2.01.
In the event of any Conversion of Eurocurrency Rate Loans on any day other than
the last day of the Interest Period applicable thereto, the Borrower requesting
the same shall be obligated, if necessary, to reimburse the Banks in respect
thereof pursuant to Section 2.12. Each Conversion Notice must be given not

-8-
14
later than 11:00 a.m. (New York time) on (i) the third Business Day prior to
the proposed Conversion Date in the case of a Conversion of Dollar denominated
Base Rate Loans into Dollar denominated Eurocurrency Rate Loans or of Dollar
denominated Eurocurrency Rate Loans of one Interest Period into Dollar
denominated Eurocurrency Rate Loans of another Interest Period, or (ii) the
fourth Business Day prior to the date of the proposed Conversion in the case of
a Conversion of Foreign Currency denominated Eurocurrency Rate Loans of one
Interest Period into Foreign Currency denominated Eurocurrency Rate Loans of
another Interest Period, or (iii) the Business Day immediately preceding the
proposed Conversion Date in the case of a Conversion of Eurocurrency Rate Loans
denominated in Dollars into Base Rate Loans. Each notice of a Conversion given
by a Borrower shall specify (A) the Conversion Date for such Conversion, (B)
the Loans to be Converted, (C) the Type of Loans to which such Loans are to be
Converted, (D) the currency of the Loans to be Converted and (E) in the case of
a Conversion into Eurocurrency Rate Loans, the Interest Period for such
Converted Loans, and shall be in substantially the form of Exhibit 2.02(c). If
a Borrower shall fail to give a timely Conversion Notice conforming to the
requirements of this Agreement with respect to any Eurocurrency Rate Loans
denominated in Dollars prior to the expiration of the Interest Period
applicable thereto, such Eurocurrency Rate Loans shall, automatically on the
last day of such Interest Period, be Converted into Base Rate Loans. If a
Borrower shall fail to give a timely Conversion Notice conforming to the
requirements of this Agreement with respect to any Eurocurrency Rate Loans
denominated in a Foreign Currency prior to the expiration of the Interest
Period applicable thereto, such Eurocurrency Rate Loans shall, automatically on
the last day of such Interest Period, be converted into a Eurocurrency Rate
Loan with an Interest Period of one month. Each Conversion Notice shall be
irrevocable and binding on the Borrower requesting such Conversion.

Section 2.03 Issuing and Reimbursing the Letters of Credit.
(a) Each Letter of Credit shall, subject to the terms of this Agreement, be
issued upon the written, facsimile transmitted request (an original of which
shall be immediately forwarded by overnight courier to the Issuing Bank) or
such other computerized issuance or application procedure, instituted from time
to time by the Issuing Bank and agreed to by the US Borrower, of the US
Borrower given to the Issuing Bank not later than 12:00 noon (New York time) on
the third Business Day prior to the proposed date of issuance of such Letter of
Credit. Each such request for a Letter of Credit (a "Letter of Credit
Request") made by the US Borrower shall be substantially in the form of Exhibit
2.03 hereto and shall specify the Business Day on which such Letter of Credit
is to be issued, the currency of such Letter of Credit, the beneficiary of such
Letter of Credit, the amount of such Letter of Credit, the draw conditions
applicable thereto and the Person on whose behalf the Letter of Credit is to be
issued, and shall provide for an expiry date which is not later than thirty
(30) months from the issuance date and each Letter of Credit which is
self-extending beyond its expiration date must be cancelable upon at least
thirty (30) days notice given by the Issuing Bank to the beneficiary of such
Letter of Credit. Such request shall also include any documents that the
Issuing Bank has specified in writing to the US Borrower that it customarily
requires in connection therewith to the extent such documents are applicable.
No Letter of Credit may have an expiry date later than twelve (12) months after
the

-9-
15
Termination Date, provided that for any Letter of Credit outstanding after the
Termination Date, the US Borrower shall provide Cover in accordance with the
terms of Section 2.06.

(b) Upon satisfaction of the applicable terms and
conditions set forth in Article III, the Issuing Bank shall issue such Letter
of Credit to the specified beneficiary not later than the close of business
(New York time) on the date so specified. The Issuing Bank shall promptly
provide to the Agent for distribution to, or directly to, each other member of
the Bank Group a summary report of all Outstanding Letters of Credit issued by
the Issuing Bank upon the issuance of each Letter of Credit, at the end of each
calendar month or at such other times as reasonably requested by a member of
the Bank Group, but any failure of the Issuing Bank to provide such Persons
with a copy of such report or Letter of Credit shall not in any way affect the
US Borrower's obligation to reimburse the Issuing Bank for any amount paid by
the Issuing Bank under any Letter of Credit or the Banks' obligations to
reimburse the Issuing Bank for such amount, to the extent provided herein, in
the event the US Borrower fails to do so. Each such Letter of Credit shall (i)
provide for the payment of drafts or other forms of demand to be presented for
honor thereunder by the beneficiary in accordance with the terms thereof, at
sight when accompanied by the documents described therein; and (ii) be subject
to the Uniform Customs and Practice for Documentary Credits (1993 Revision),
International Chamber of Commerce Publication No. 500, (or any subsequent
revisions thereof issued by the International Chamber of Commerce and adhered
to by the Issuing Bank) (the "UCP"); and (iii) as to matters not governed by
the UCP, be governed by, and construed and interpreted in accordance with, the
governing law specified in this Agreement.

(c) Upon presentment to the Issuing Bank of any demand
for honor under any Letter of Credit by the beneficiary thereof and the
determination by the Issuing Bank that such demand is in order, the Issuing
Bank shall give prompt notice (a "Reimbursement Notice") to the US Borrower of
(i) the Letter of Credit to which such Reimbursement Notice relates, (ii) the
amounts and the currency to be paid on account of such demand (the
"Reimbursement Amount") and (iii) the date on which such amounts are to be paid
(the "Reimbursement Date"), but any failure to so notify the US Borrower shall
not in any way affect the US Borrower's obligations to reimburse the Issuing
Bank for any amount paid by the Issuing Bank under any Letter of Credit. In
determining whether to pay under any Letter of Credit, the Issuing Bank shall
not have any obligation relative to the US Borrower and the Banks other than
the obligations imposed on issuing banks under the UCP and applicable law. Any
action taken or omitted to be taken by the Issuing Bank under or in connection
with any Letter of Credit, if taken or omitted in the absence of gross
negligence or willful misconduct (as determined by a court of competent
jurisdiction by final and non-appealable judgment), shall not create for the
Issuing Bank any resulting liability to the US Borrower or the Banks, IT BEING
UNDERSTOOD THAT ANY ACT OR OMISSION CONSTITUTING ORDINARY NEGLIGENCE (WHETHER
SOLE OR CONTRIBUTORY) SHALL NOT RESULT IN ANY RESULTING LIABILITY FOR THE
ISSUING BANK.

(d) Upon receipt of any Reimbursement Notice, the US
Borrower shall reimburse the Issuing Bank by forthwith paying to the
Administrative Agent for the benefit of the Issuing Bank (who shall promptly
notify the Issuing Bank of such payment) no later than 10:00 a.m. (New York

-10-
16
time) on the Reimbursement Date specified in such Reimbursement Notice an
amount equal to the Reimbursement Amount specified in such Reimbursement
Notice, together with interest from such Reimbursement Date until such
reimbursement is made by the US Borrower at a fluctuating rate per annum equal
to the lesser of (i) the Highest Lawful Rate and (ii) the Base Rate in effect
during the time such reimbursement obligation remains unpaid plus the
Applicable Margin for Base Rate Loans from such Reimbursement Date until the
third day immediately following the delivery of such Reimbursement Notice by
the Issuing Bank to the US Borrower and thereafter, the Default Rate. To the
extent availability may then exist (including requirements as to minimum
amounts), and upon compliance with the relevant terms and conditions of this
Agreement, the US Borrower may repay any or all of the obligations described in
this paragraph by requesting a Borrowing of Loans and applying the proceeds
thereof accordingly, together with any amounts owed under Section
2.01(c)(iii)(y).

(e) If the US Borrower shall fail to reimburse the
Issuing Bank for any payment by the Issuing Bank under a Letter of Credit by
12:00 noon. (New York time) on the Reimbursement Date specified in the
Reimbursement Notice related thereto, the Administrative Agent shall give
prompt notice thereof to each other member of the Bank Group. Upon receipt of
such notice, each Bank shall, notwithstanding any other provision of this
Agreement (including the occurrence and continuance of a Default or an Event of
Default), make available to the Administrative Agent for the benefit of the
Issuing Bank an amount equal to its Commitment Percentage of the Reimbursement
Amount and in the same currency as specified in the related Reimbursement
Notice no later than the close of business on such Reimbursement Date. If such
Reimbursement Amount is not in fact made available to the Administrative Agent
by such Bank on such Reimbursement Date, such Bank shall pay to the
Administrative Agent for the account of the Issuing Bank, on demand made by the
Issuing Bank, in addition to such Reimbursement Amount, interest on such amount
for the number of days that elapse from such Reimbursement Date to the date on
which the amount equal to such Bank's Commitment Percentage of such
Reimbursement Amount becomes immediately available to the Issuing Bank at a
rate per annum equal to the average daily Federal Funds Rate for such days.
Any amount received by the Administrative Agent or the Issuing Bank from the US
Borrower in respect of a demand honored under a Letter of Credit after one or
more of the Banks have made funds available for the payment of such demand
pursuant to this paragraph shall be paid over by the Administrative Agent or
the Issuing Bank, as the case may be, to such Banks, pro rata according to the
amounts so made available by such Banks, promptly upon receipt by the
Administrative Agent or the Issuing Bank of such amount. Nothing in this
Agreement shall diminish the US Borrower's obligation under this Agreement to
provide the funds for the payment of, or on demand to reimburse the Issuing
Bank for payment of, any demand presented to, and duly honored by, the Issuing
Bank under any Letter of Credit.

(f) In order to induce the issuance of Letters of Credit
by the Issuing Bank and the purchase of participations therein by the Banks,
the US Borrower irrevocably agrees (i) that the obligation of the US Borrower
to reimburse the Issuing Bank for amounts paid by the Issuing Bank under any
Letter of Credit, including accrued interest thereon, as set forth herein is
absolute and unconditional, (ii) that no member of the Bank Group shall be
responsible or liable for, and the US

-11-
17
Borrower's unconditional obligation to reimburse the Issuing Bank through the
Administrative Agent for amounts paid by the Issuing Bank on account of demands
duly honored under the Letters of Credit shall not be affected by, any
circumstance, act or omission whatsoever relating to any Letter of Credit,
whether or not known to any member of the Bank Group, unless such circumstance,
act or omission results in the wrongful payment of any Letter of Credit and
such circumstance, act or omission constitutes the gross negligence or willful
misconduct (as determined by a court of competent jurisdiction by final and
non-appealable judgment) on the part of such member of the Bank Group, (iii)
that any action taken or omitted to be taken by any member of the Bank Group
under or in connection with any Letter of Credit or any related demand,
document or property shall be binding on the US Borrower and shall not put any
member of the Bank Group under any resulting liability to the US Borrower,
unless such action or omission results in the wrongful payment of any Letter of
Credit and such action or omission constitutes the gross negligence or willful
misconduct (as determined by a court of competent jurisdiction by final and
non-appealable judgment) on the part of such member of the Bank Group and (iv)
to indemnify, defend and hold each member of the Bank Group harmless from and
against any and all liabilities, damages, claims or reasonable expenses
(including reasonable attorneys' fees and amounts paid in settlement) arising
out of or based on any Letter of Credit, except to the extent the same is the
result of the wrongful payment of any Letter of Credit and such wrongful
payment constitutes gross negligence or willful misconduct (as determined by a
court of competent jurisdiction by final and non-appealable judgment) on the
part of the Person seeking indemnity hereunder, IT BEING THE EXPRESS INTENTION
OF THE US BORROWER THAT EACH MEMBER OF THE BANK GROUP SHALL BE INDEMNIFIED AND
HELD HARMLESS AGAINST AND SHALL NOT HAVE ANY LIABILITY OR OBLIGATION FOR ANY
AND ALL LIABILITIES, CLAIMS, OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING
FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE, CONCURRENT, OR CONTRIBUTORY) OF
SUCH MEMBER OF THE BANK GROUP. The US Borrower hereby waives presentment for
payment and notice of dishonor, protest and notice of protest with respect to
demands honored under the Letters of Credit.

(g) The provisions of this Agreement and the other Loan
Documents concerning collateral, timing of payments, interest rates applicable
to any reimbursement obligation relating to any Letter of Credit, any
representations, warranties, covenants, events of default, remedies and
governing law shall supersede in their entirety the provisions of any Letter of
Credit application relating to such matters. In the event any other provision
of any Letter of Credit application is inconsistent with, or in conflict of any
provision of this Agreement or any Loan Documents, the provisions of this
Agreement or the Loan Documents shall govern.

and each other member of the Bank Group that the circumstances causing such
suspension no longer exist, and each Loan denominated in Dollars comprising
such Borrowing shall be made as, or Converted into, as applicable, a Base Rate
Loan and each Loan denominated in a Foreign Currency shall be exchanged for the
Equivalent thereof in Dollars and converted into Base Rate Loans.

date, the ratio of (i) the Parent's total consolidated Indebtedness as of the
calendar quarter ending on such date, to (ii) its consolidated EBITDA for the
twelve month period ending on the last day of such calendar quarter.

The Margin Ratio set forth in the most recent Margin Ratio
Certificate delivered to the Administrative Agent shall, for purposes of
determining the Applicable Margin, be in effect from the second business day
after the date such Margin Ratio Certificate is delivered (or is required to be
delivered), until the second business day after the next such Margin Ratio
Certificate is delivered (or is required to be delivered), with the following
exceptions: (a) if the Administrative Agent in good faith determines that the
calculations of the Margin Ratio reflected in any Margin Ratio Certificate are
not accurate, the Administrative Agent may correct any error and calculate the
appropriate Margin Ratio (and promptly give the Borrowers notice thereof with
supporting documentation and calculations), (b) if the Parent fails to deliver
any Margin Ratio Certificate when due, the Margin Ratio shall be deemed to be
greater than 3.5 to 1.0 until such Margin Ratio Certificate is delivered, and
(c) for the period commencing on the Execution Date and ending on the date the
first Margin Ratio Certificate is due hereunder, the Margin Ratio shall be

-17-
23
principal amount thereof, and if such notice is given such Borrower shall,
prepay the outstanding principal amount of the Base Rate Loans made to such
Borrower and comprising part of the same Borrowing in whole or ratably in part;
provided, that any partial prepayment of such Base Rate Loans shall be in an

amount of the Eurocurrency Rate Loans made to such Borrower and comprising part
of the same Borrowing in whole or ratably in part; provided, that any partial
prepayment of such Eurocurrency Rate Loans shall be in an aggregate principal
amount of not less than $2,000,000 or an integral multiple of $1,000,000 in
excess thereof (or, in the case of Foreign Currency denominated Loans, the
Equivalent thereof in Dollars as of the Date of Determination).

(b) Each prepayment of Loans made pursuant to this
Section 2.08 shall be accompanied by a payment of accrued interest to the date
of such prepayment on the principal amount prepaid. In the event of any
prepayment of a Eurocurrency Rate Loan, the Borrower making such prepayment
shall be obligated to reimburse the Banks for funding losses, if any, pursuant
to Section 2.12.

Section 2.09 Payments, Notice of Certain Repayments and
Computations. (a) Except with respect to principal of, interest on and other
amounts arising from, or incurred in respect of, Loans or Letters of Credit
denominated in a Foreign Currency, all payments of principal, interest,
commitment fees and other amounts hereunder, under the Notes and the other
Loan Documents shall be made in Dollars to the Administrative Agent at the
applicable Agent Account in immediately available funds not later than 11:00
a.m. (New York time) on the date when due. Unless otherwise specified herein,
all payments of principal, interest and other amounts hereunder, under the
Notes and the other Loan Documents denominated in a Foreign Currency shall be
made in the same Foreign Currency to the Administrative Agent (or the Issuing
Bank with respect to Letters of Credit) at the applicable Agent Account in
immediately available funds not later than 11:00 a.m. (at the time of the
jurisdiction in which the applicable Agent's Account for such Foreign Currency
is located) on the date when due. Upon receipt of such payments, the
Administrative Agent will promptly cause to be distributed like funds and in
like currencies relating to the payment of principal or interest or commitment
fees ratably (other than amounts payable pursuant to Section 2.11, Section
2.12, Section 2.13 or Section 2.14) to the Banks, for the account of their
respective Applicable Lending Offices, and like funds in like currencies
relating to the payment of any other amount payable to any Bank, to such Bank
for the account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement.

(b) Unless the Administrative Agent shall have received
notice from the Borrower required to make any payment hereunder prior to the
date on which any payment is due to the Banks under the Loan Documents that
such Borrower will not make such payment in full, the Administrative Agent may
assume that such Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such

-18-
24
assumption, cause to be distributed to each Bank on such due date an amount
equal to the amount then due such Bank. If and to the extent such Borrower
shall not have made such payment in full to the Administrative Agent, each Bank
shall repay to the Administrative Agent forthwith on demand such amount
distributed to such Bank, together with interest thereon for each day from the
date such amount is distributed to such Bank until the date such Bank repays
such amount to the Administrative Agent at the Federal Funds Rate.

(c) All payments by the Borrowers of the fees payable to
the Administrative Agent or the Issuing Bank shall be made in Dollars directly
to such Person at its address specified in Section 10.03 in immediately
available funds not later than 11:00 a.m. (New York time) on the date when due.

(d) All computations of interest based on the Prime Rate
shall be made on the basis of a year of 365 or 366 days, as the case may be,
and all computations of interest based on the Eurocurrency Rate or the Federal
Funds Rate shall be made on the basis of a year of 360 days (unless use of a
360 day year would cause the interest contracted for, charged or received
hereunder to exceed the Highest Lawful Rate, in which case such computations
shall be made on the basis of a year of 365 or 366 days, as the case may be),
in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or
commitment fees are payable.

(e) Whenever any payment under the Loan Documents shall
be stated to be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest or fees, as the
case may be; provided, if such extension would cause payment of interest on or
principal of Eurocurrency Rate Loans to be made in the next following calendar
month, such payment shall be made on the immediately preceding Business Day.

(f) If any Bank shall obtain any payment (whether
voluntary, involuntary, through the exercise of any right of setoff, or
otherwise) on account of the Loans made by it (other than pursuant to Section
2.11, Section 2.12, Section 2.13 or Section 2.14), or payments by the Issuing
Bank made pursuant to Section 2.03, in excess of its ratable share of payments
on account of the Loans or payments by the Issuing Bank made pursuant to
Section 2.03, obtained by all the Banks, such Bank shall forthwith purchase
from the other Banks such participations in the Loans made by such other Banks,
or the reimbursement obligations in respect of the payments by the Issuing Bank
made pursuant to Section 2.03, as the case may be, as shall be necessary to
cause such purchasing Bank to share the excess payment ratably with each of
them. The Borrowers agree that any Bank so purchasing a participation from
another Bank pursuant to this Section 2.09(f) may exercise all its rights of
payment (including the right of setoff) with respect to such participation as
fully as if such Bank were the direct creditor of the Borrowers in the amount
of such participation.

(g) To the extent that the Administrative Agent receives
funds for application to the amounts owing by any Borrower under or in respect
of this Agreement or any Note in currencies

-19-
25
other than the currency or currencies required to enable the Administrative
Agent to distribute funds to the Banks in accordance with the terms of this
Section 2.09, the Administrative Agent shall be entitled to convert or exchange
such funds into Dollars or into a Foreign Currency or from Dollars to a Foreign
Currency, as the case may be, to the extent necessary to enable the
Administrative Agent to distribute such funds in accordance with the terms of
this Section 2.09; provided that if such conversion results in the receipt by
the Administrative Agent (acting reasonably and in good faith in making such
conversion) of an insufficient amount of the currency required to be
distributed, the applicable Borrower shall pay promptly such additional amount
as may be necessary to compensate and indemnify the Administrative Agent for
such shortfall.

Section 2.10 Fees. (a) Subject to the provisions of Section
10.13, the US Borrower and the Parent each agree to pay to each Bank, on their
respective pro rata share of the Available Revolving Commitment, a commitment
fee equal to (i) 0.375% per annum of the Available Revolving Commitment of such
Bank in effect from time to time for the period from the Execution Date until
December 31, 1997 and, (ii) thereafter to, but excluding, the Termination Date
(or if earlier, the termination in full of such Bank's Dollar Revolving
Commitment and Guilder Revolving Commitment) at the rate set forth in the
Margin Ratio grid in Section 2.07(c). Accrued commitment fees shall be due and
payable in arrears on each Payment Date in each year, on the date of any
reduction or termination of the Dollar Revolving Commitment and Guilder
Revolving Commitment of such Bank and on the Termination Date (or if earlier,
the termination in full of such Bank's Dollar Revolving Commitment and Guilder
Revolving Commitment); and shall be computed for the period commencing with the
day to which such fee was last paid (or, in the case of the first commitment
fee payment date, for the period commencing with and including the Execution
Date) to the date such fee is due and payable. All commitment fees shall be
paid in immediately available funds, and shall be based on a 360-day year and
actual days elapsed.

(b) (i) The US Borrower agrees to pay the Administrative
Agent, for the account of the Banks, a fee in respect of each Letter of Credit
issued for the account of the US Borrower (the "L/C Fees") for the period from
the date of issuance of such Letter of Credit to and including the expiry of
such Letter of Credit computed at a rate per annum equal to the greater of: (i)
$500 or (ii) the Applicable Margin for Eurocurrency Loans multiplied by the
face amount of such Letter of Credit. For any Letter of Credit issued with a
face amount denominated in a currency other than Dollars, the L/C Fees will be
converted into the Equivalent thereof in Dollars as of the issuance date of
such Letter of Credit, and thereafter as of the first day of each calendar
quarter. All L/C Fees shall be paid in immediately available funds and shall
based on a 360 day year and actual days elapsed. Accrued L/C Fees for each
Letter of Credit shall be due and payable in arrears on each Payment Date (or
if earlier, the termination in full of the Dollar Revolving Commitments);
provided, if the L/C Fee is the $500 minimum, such $500 shall be paid in full
on the first Payment Date after the issuance of such Letter of Credit. No
additional fees shall be payable hereunder from any of the Borrowers or to any
of the Banks in respect of Existing Letters of Credit, if the minimum fee in
effect at the time of issuance of such Existing Letters of Credit has
previously been paid.

-20-
26

(ii) In addition to the L/C Fees, the US Borrower agrees
to pay the Issuing Bank, solely for the Issuing Bank's account, a per annum fee
in respect of each Letter of Credit issued by the Issuing Bank for the account
of the US Borrower (the "Facing Fees"), equal to the greater of: (i) $500 or
(ii) 1/8% of the face amount of such Letter of Credit. For any Letter of
Credit issued with a face amount denominated in a currency other than Dollars,
the Facing Fees will be converted into the Equivalent thereof in Dollars as of
the issuance date of such Letter of Credit, and thereafter as of the first day
of each calendar quarter. All Facing Fees shall be paid in immediately
available funds. Accrued Facing Fees for each Letter of Credit shall be due
and payable in arrears on each Payment Date (or if earlier, the termination in
full of the Dollar Revolving Commitments); provided, if the Facing Fee is the
$500 minimum, such $500 shall be paid in full on the first Payment Date after
the issuance of such Letter of Credit. In addition to the Facing Fees, the US
Borrower shall pay the Issuing Bank, solely for the Issuing Bank's account, its
customary service charges relating to the amendment to, and transfer of any
Letters of Credit. Such amounts to be due and payable when such services are
rendered by the Issuing Bank. No Facing Fees shall be due and payable in
connection with the Existing Letters of Credit.

(iii) The Administrative Agent shall distribute all L/C
Fees collected during the quarterly period then ended to the Banks ratably
according to their respective Commitment Percentages.

(c) Subject to the provisions of Section 10.13, the
Borrowers shall pay the Administrative Agent, solely for the Administrative
Agent's account, or to the Syndication Agent for the Syndication Agent's
account, as applicable, such other fees as agreed to in writing among the
Borrowers, the Administrative Agent and the Syndication Agent, when and as due.

Section 2.11 Setoff, Counterclaims and Taxes. (a) All
payments of principal, interest, expenses, reimbursements, compensation,
commitment fees, letter of credit fees, facing fees, arrangement fees or
administration fees and any other amount from time to time due under the Notes,
this Agreement or any other Loan Document shall be made by the relevant
Borrowers without setoff or counterclaim and shall be made free and clear of
and without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding, in the case of each member of the Bank Group, taxes imposed on its
income or gross receipts, and franchise taxes imposed on it, by the
jurisdiction under the laws of which such member of the Bank Group is organized
or any political subdivision thereof and, in the case of each Bank, taxes
imposed on its income, and franchise taxes imposed on it, by the jurisdiction
of such Bank's Applicable Lending Office or any political subdivision thereof
(all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "Taxes"). If any
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Loan Document to any member of the Bank
Group, (i) the sum payable shall be increased as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 2.11) such member of the Bank Group receives an
amount equal to the sum it would have received had no such deductions been
made, (ii) such Borrower shall make such deductions and (iii) such Borrower
shall

-21-
27
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

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

(c) Each Borrower will indemnify each member of the Bank
Group for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 2.11) paid, by such member of the Bank Group
(whether paid on its own behalf or on behalf of any other member of the Bank
Group) and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto. This indemnification shall be made within
10 days from the date such member of the Bank Group makes written demand
therefor; provided that no Borrower shall be obligated to indemnify any member
of the Bank Group for any Taxes incurred as the result of a material inaccuracy
of the representations and warranties made by it under Section 2.11(f) (unless
such inaccuracy is the result of a change in an applicable Requirement of Law)
or the failure by such Person to comply with its obligations in Section
2.11(f).

(d) Within 30 days after the date of any payment of
Taxes, the relevant Borrower will furnish to the Administrative Agent, at its
address referred to in Section 10.03, the original or a certified copy of a
receipt evidencing payment thereof.

(e) Without prejudice to the survival of any other
agreement of the Borrowers hereunder, the agreements and obligations of the
Borrowers contained in this Section 2.11 shall survive the payment in full of
the Credit Outstanding and all other amounts owing under the other Loan
Documents. The provisions of this Section 2.11 are in all respects subject to
Section 10.13 hereof.

(f) Each Bank shall (i) promptly after the Effective Date
or promptly after the date of the Assignment and Acceptance, pursuant to which
it became a Bank in the case of each other Bank and (ii) from time to time
thereafter upon the obsolescence or expiration of any previously delivered form
or certificate (but only so long as such Bank remains lawfully able to do so),
provide the Borrowers and the Administrative Agent with any form or certificate
that is required by any taxing authority, including, if applicable, two
original Internal Revenue Service forms 1001 or 4224, as appropriate (or any
successor form or other form prescribed by the Internal Revenue Service), an
original Internal Revenue Service form W-9 (or any successor form), or such
other forms as shall be appropriate to establish, subject to the last sentence
of this Section 2.11(f), that such Bank is (y) exempt from Home Jurisdiction
Withholding Taxes on payments pursuant to this Agreement, the Notes or any
other Loan Document (or, in the case of a Bank that becomes a party to this
Agreement pursuant to Section 10.02(a) and (z) exempt from or entitled to a
reduced rate of

-22-
28
Home Jurisdiction Withholding Taxes on payments pursuant to this Agreement, the
Notes or any other Loan Document that is no greater than the rate to which the
assigning Bank was entitled). Each member of the Bank Group represents and
warrants that such information is true and complete in all material respects as
of the date it is delivered. Each Bank shall promptly notify the Borrowers and
the Administrative Agent if, because of any change in the jurisdiction of
organization or an Applicable Lending Office of such Bank, (A) it is required
to withdraw or cancel any form or certificate previously submitted by it or any
form or certificate has otherwise become ineffective or inaccurate or (B)
payments to it are or will be subject to withholding of any Home Jurisdiction
Withholding Tax to a greater or lesser extent than the extent to which payments
to it pursuant to this Agreement, the Notes or any other Loan Document were
previously subject. If any form or document referred to in this Section
2.11(f) requires the disclosure of information, other than information
necessary to compute the tax payable and information required on the date
hereof by Internal Revenue Service form 1001 or 4224, that the Bank reasonably
considers to be confidential, the Bank shall give notice thereof to the
Borrowers and the Administrative Agent and shall not be obligated to include in
such form or document such confidential information; provided, however, such
form or document will state that such confidential information may be requested
directly from the Bank.

(g) If a Bank shall receive a refund of any Taxes paid by
a Borrower pursuant to this Section 2.11 by reason of the fact that such Taxes
were not correctly or legally asserted, the Bank shall within 90 days after
receipt of such refund pay to such Borrower the amount of such refund along
with any interest actually received by such Bank thereon, if any; provided,
however, that such payments shall be required only to the extent any Bank can
determine, in its good faith judgment, that such refunds are attributable to
payments made by or on behalf of such Borrower; and provided, further, that no
Bank shall have any obligation under this Agreement to claim or otherwise seek
to obtain any such refund, but agrees to use reasonable efforts to assist a
Borrower in doing so.

Section 2.12 Funding Losses. Each of the Borrowers hereby
indemnifies each Bank against any loss or reasonable expense (including, but
not limited to, any loss or reasonable expense sustained or incurred or to be
sustained or incurred in liquidating or reemploying deposits from third parties
acquired to effect or maintain such Loan or any part thereof as a Eurocurrency
Rate Loan) which such Bank may sustain or incur as a consequence of (a) any
failure by any of the Borrowers to fulfill on the date of any Borrowing the
applicable conditions set forth in Article III, (b) any failure by any of the
Borrowers to borrow hereunder, to Convert Loans hereunder after a Borrowing
Request or Conversion Notice, respectively, has been given by such Borrower,
(c) any payment, prepayment or Conversion of a Eurocurrency Rate Loan required
or permitted by any other provisions of this Agreement, including, without
limitation, payments made due to the acceleration of the maturity of the Notes
pursuant to Section 7.01, or otherwise made on a date other than the last day
of the applicable Interest Period, (d) any default in the payment or prepayment
of the principal amount of any Loan or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, by notice of
prepayment or otherwise) or (e) the occurrence of an Event of Default. Such
loss or reasonable expense shall include, without limitation, an amount equal
to the excess, if any, as determined by each Bank of (i) its cost of obtaining
the funds for the Loan being

-23-
29
paid, prepaid or Converted or not borrowed or Converted (based on the
Eurocurrency Rate applicable thereto) for the period from the date of such
payment, prepayment or Conversion or failure to borrow or Convert to the last
day of the Interest Period for such Loan (or, in the case of a failure to
borrow or Convert, the Interest Period for the Loan which would have commenced
on the date of such failure to borrow or Convert) over (ii) the amount of
interest (as estimated by such Bank) that would be realized by such Bank in
reemploying the funds so paid, prepaid or Converted or not borrowed or
Converted for such period or Interest Period, as the case may be. Each
Borrower shall pay to the Administrative Agent for the account of each Bank the
amount shown as due on any certificate received by it under Section 2.15 within
ten (10) days after its receipt of the same. Notwithstanding the foregoing, in
no event shall any Bank be permitted to receive any compensation hereunder
constituting interest in excess of the Highest Lawful Rate. Without prejudice
to the survival of any other obligations of the Borrowers hereunder, but
subject to the last sentence of Section 2.15, the obligations of the Borrowers
under this Section 2.12 shall survive the termination of this Agreement and/or
the payment or assignment of any of the Notes.

Section 2.13 Change of Law. (a) If at any time after the
Effective Date any Bank determines in good faith (which determination shall be
presumed correct) that any change in any applicable Requirement of Law, or in
the interpretation, application or administration thereof makes it unlawful, or
any central bank or other Governmental Authority asserts that it is unlawful,
for such Bank or its Eurocurrency Lending Office to fund or maintain any
Eurocurrency Rate Loan in a particular currency (any of the foregoing
determinations being a "Eurocurrency Event"), then, such Bank, at its option,
may: (i) declare that Eurocurrency Rate Loans in such currency will no longer
be made or maintained by such Bank, whereupon the right of the Borrowers to
select Eurocurrency Rate Loans in such currency for any Borrowing shall be
suspended until such Bank shall notify the Administrative Agent that the
circumstances causing such Eurocurrency Event no longer exist; (ii) with
respect to any Eurocurrency Rate Loans in such currency of such Bank then
outstanding, require that (A) if such Eurocurrency Rate Loans are denominated
in Dollars, such affected Loans shall be Converted to Base Rate Loans and (B)
if such Eurocurrency Loans are denominated in a Foreign Currency, such affected
Loans shall be exchanged for the Equivalent thereof in Dollars and converted to
Base Rate Loans, in which event all such Eurocurrency Rate Loans shall
automatically be Converted into Base Rate Loans on the effective date of such
notice and all payments or prepayments of principal that would have otherwise
been applied to repay such Converted Eurocurrency Rate Loans shall instead be
applied to repay the Base Rate Loans resulting from such Conversion; and/or
(iii) with respect to any Eurocurrency Rate Loans in such currency requested of
such Bank but not yet made as or Converted into such, require that such
Eurocurrency Rate Loans in such currency be made as or Converted into, as
applicable, Base Rate Loans.

(b) Upon the occurrence of any Eurocurrency Event, and at
any time thereafter so long as such Eurocurrency Event shall continue, such
Bank may exercise its aforesaid option by giving written notice thereof to the
Administrative Agent and the Borrowers, such notice to be effective upon
receipt thereof by the Borrowers. Any Conversion of any Eurocurrency Rate Loan
which is required under this Section 2.13 shall be made, together with accrued
and unpaid interest and all other amounts payable to such Bank under this
Agreement with respect to such Converted

-24-
30
Loan (including, without limitation, amounts payable pursuant to Section 2.12
hereof), on the date stated in the notice to the Borrowers referred to above.

Section 2.14 Increased Costs. (a) If, due to either (i) any
Requirement of Law or (ii) the compliance with any guideline by any central
bank or other Governmental Authority (whether or not having the force of law),
there shall be any increase in the cost to any Bank of agreeing to make or
making, funding or maintaining Eurocurrency Rate Loans, then the Borrowers
shall from time to time, subject to the provisions of Section 2.15 and Section
10.13, pay to the Administrative Agent for the account of such Bank additional
amounts sufficient to compensate such Bank for such increased cost within 10
days after the receipt by any of the Borrowers of a certificate received under
Section 2.15 showing the amount due.

(b) If any Bank shall have determined in good faith that
any law, rule, regulation or guideline adopted pursuant to or arising out of
the July 1988 report of the Basle Committee on Banking Regulations and
Supervisory Practices entitled "International Convergence of Capital
Measurement and Capital Standards" or that the adoption of any applicable law,
rule, regulation or guideline regarding capital adequacy, or any change in any
of the foregoing or in the interpretation or administration thereof by any
central bank or other Governmental Authority charged with the interpretation or
administration thereof, or compliance by such Bank (or any Applicable Lending
Office of such Bank) with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such Governmental Authority or
comparable agency, increases the amount of capital required or expected to be
maintained by such Bank or any corporation controlling such Bank from the level
required as of the Effective Date, then the Borrowers shall from time to time,
subject to the provisions of Section 2.15 and Section 10.13, pay to such Bank
additional amounts sufficient to compensate such Bank or such corporation in
the light of such circumstances, to the extent that such Bank reasonably
determines such increase in capital to be allocable to the existence of such
Bank's Commitment hereunder.

(c) If any law, executive order or regulation is adopted
or interpreted by any central bank or other Governmental Authority so as to
affect any of the Borrowers' obligations or the compensation to any Bank or the
Issuing Bank in respect of the Letters of Credit or the cost to such Bank or
the Issuing Bank of establishing and/or maintaining the Letters of Credit (or
any participation therein), then the affected Borrower shall from time to time,
subject to the provisions of Section 2.15 and Section 10.13, reimburse or
indemnify such Bank or the Issuing Bank, as the case may be, with respect
thereto so that such Bank or the Issuing Bank, as the case may be, shall be in
the same position as if there had been no such adoption or interpretation. The
protection of this Section 2.14 shall be available to the Issuing Bank and the
Banks regardless of any possible contention of invalidity or inapplicability of
law, regulation or condition which shall have been imposed.

Section 2.15 Claims Certificate. (a) Each Bank or the
Issuing Bank, as the case may be, will notify the Borrowers of any event
occurring after the date of this Agreement which will entitle such Bank or the
Issuing Bank, as the case may be, to compensation or indemnification

-25-
31
pursuant to Section 2.11 through Section 2.14 as promptly as practicable after
such Bank obtains actual knowledge of the occurrence of such event, and, in any
event, within 180 days thereof. A certificate of such Bank or the Issuing
Bank, as the case may be, setting forth in reasonable detail (i) such amount or
amounts as shall be necessary to compensate such Bank (or participating banks
or other entities pursuant to Section 10.02) or the Issuing Bank, as the case
may be, as specified above and (ii) the calculation of such amount or amounts
shall be delivered to the Borrowers (with a copy to the Administrative Agent)
and shall be conclusive absent manifest error. The Borrowers shall pay to such
Bank or to the Issuing Bank, as the case may be, the amount shown as due on any
such certificate within ten (10) days after its receipt of the same. Subject to
the last sentence of this Section 2.15, the failure of any Bank or the Issuing
Bank to demand any such compensation or indemnification shall not constitute a
waiver of the right of such Bank, any other Bank or the Issuing Bank, to demand
any such compensation or indemnification as such rights are set forth herein.

(b) In the event any Bank gives a notice to a Borrower
pursuant to Section 2.07(b), Sections 2.11 through 2.14 that it cannot fund
certain Loans or that such funding will be at an increased cost or a higher
interest rate, or is unable to deliver the forms as required by Section 2.11,
the affected Borrower may give notice in response, with copies to the
Administrative Agent, that it wishes to seek one or more banks to replace such
Bank in accordance with the provisions set forth in Section 10.02. Each Bank
giving such a notice agrees that, at the request of such Borrower, it will
assign all of its interests hereunder and under the Notes and the Commitment to
a designated, Eligible Assignee for the full amount then owing to it, all in
accordance with Section 10.02. Thereafter, said assignee shall have all of the
rights hereunder and obligations of the assigning Bank (except as otherwise
expressly set forth herein) and such Bank shall have no further obligations to
any Borrower hereunder. Unless otherwise agreed by the Majority Banks, any
such assignment of one Borrower's Loans shall only be made if all other
Borrowers' Loans to such Bank are likewise assigned.

(c) Any notice given pursuant to this Section 2.15 shall
be deemed to contain a representation by the Bank issuing such notice that: (i)
such Bank has used reasonable efforts to minimize said costs or charges but
cannot, in its sole judgment, do so at reasonable expense, and (ii) the
increased costs and charges are common to substantially all of the comparable
loan customers of such Bank and are not unique to the Borrowers.

In order to induce the Bank Group to enter into this
Agreement, each Borrower hereby represents and warrants to the Bank Group as
follows:

Section 4.01 Corporate Existence. Each of the Borrowers and
its Subsidiaries is a corporation (or other Person) duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, and is duly qualified or licensed to transact
business as a foreign corporation (or other Person) and is in good standing
under the laws of each jurisdiction in which the conduct of its operations or
the ownership or leasing of its properties requires such qualification or

complete list of

-29-
35
all of the direct or indirect Subsidiaries of the Parent as of the Effective
Date (subsequent to the Saybolt acquisition) indicating the name of its parent.
Schedule 4.01 will be supplemented within fifteen (15) days from the Execution

of the Loan Documents to which any Credit Party is a party and the consummation
of the transactions contemplated thereby have been duly authorized by all
necessary corporate action (or comparable action, in the case of a Credit Party
that is not a corporation). Each of the Loan Documents to which any Credit
Party is a party has been duly executed and delivered by such Person, is in
full force and effect and constitutes the legal, valid and binding obligation
of such Person, enforceable against it in accordance with its terms, except (a)
as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws or judicial decisions
affecting the enforcement of creditor's rights generally and general principles
of equity, and (b) that (i) the rights and remedies afforded the Bank Group
under the Security Documents relating to the Collateral and (ii) the rights and

the jurisdiction in which the issuer of such Collateral was organized.

Section 4.03 No Conflict. The execution, delivery and
performance by each Credit Party of each Loan Document to which such Person is
a party and the consummation of each of the transactions contemplated thereby
do not and shall not, by the lapse of time, the giving of notice or otherwise:
(a) constitute a violation of any Requirement of Law or a breach of any
provision contained in the articles or certificate of incorporation or bylaws
or other applicable governance documents of such Person, or any shareholder
agreement pertaining to such Person, or contained in any material agreement,
instrument or document to which it is now a party or by which it or its
properties is bound, except for such violations or breaches that could not
reasonably be expected to have a Material Adverse Effect; or (b) result in or
require the creation or imposition of any Lien whatsoever upon any of the
Properties of any Credit Party or its Subsidiaries (other than Liens arising
pursuant to the Loan Documents).

Documents to which it is a party, (b) the legality, validity, binding effect or
enforceability of any of the Loan Documents, or (c) the ownership, use or
operation by the Credit Parties and their respective Subsidiaries of any of
their Properties other than those that could not reasonably be expected to have
a Material Adverse Effect.

Section 4.05 No Defaults or Violations of Law. No Default or
Event of Default has occurred and is continuing. No default (or event or
circumstance occurred which, but for the passage of time or the giving of
notice, or both, would constitute a default) has occurred and is continuing
with respect to any note, indenture, loan agreement, mortgage, lease, deed or
other agreement to which any Borrower or its Subsidiaries is a party or by
which any of them or their Properties is bound, except for such defaults that
could not reasonably be expected to have a Material Adverse Effect. Neither
the Borrowers nor any of their Restricted Subsidiaries is in violation of any
applicable Requirement of Law except for such violations that could not
reasonably be expected to have a Material Adverse Effect.

of the Parent as at December 31, 1996, and the related consolidated statements
of operations, shareholders' equity and cash flows for the fiscal year then

and comparable items for Saybolt prepared by Price Waterhouse L.L.P. as of
December 31, 1996 and for Xxxxx Xxxxxxxx prepared by Crane & Partners, as of

fairly in all material respects the consolidated financial condition of the
Persons named therein as of the date thereof and the results of its operations
for the periods then ended. No event has occurred since December 31, 1996, or

expected to have a Material Adverse Effect in respect of any of said Persons.

(b) Except as fully reflected in the audited financial
statements referred to in paragraph (a) of this Section 4.06, as of the
Execution Date, there are no liabilities or obligations of the Borrowers or any
of their Subsidiaries of any nature whatsoever (whether absolute, accrued,

in aggregate, could reasonably be expected to have a Material Adverse Effect.

(c) On and as of the Effective Date, on a pro forma basis
after giving effect to all Indebtedness incurred, and to be incurred, and Liens
created, and to be created, by each Credit Party in connection therewith, (x)
the sum of the assets, at a fair valuation, of each Credit Party will exceed
its debts, (y) no Credit Party will have incurred or intended to, or believe
that they will, incur debts

-31-
37
beyond their ability to pay such debts as such debts mature and (z) no Credit
Party will have unreasonably small capital with which to conduct its business.

Section 4.07 Litigation. Except as disclosed in Schedule
4.07, there are no actions, suits or proceedings pending or, to the knowledge
of any Borrower, threatened against or affecting any Borrower or its
Subsidiaries, or the Properties of any such Person, before or by any
Governmental Authority or other Person, which could reasonably be expected to
have a Material Adverse Effect.

Section 4.08 Use of Proceeds. (a) Each Borrower's uses of
the proceeds of the Loans made to it, and, in the case of the US Borrower, of
the Letters of Credit are, and will continue to be, legal and proper corporate
uses, and such uses do not violate and are otherwise consistent with the terms
of the Loan Documents, including, without limitation, Section 5.09, and all
Requirements of Law (including Regulations G, T, U and X).

(b) None of the Borrowers nor any of their respective
Subsidiaries is engaged in the business of extending credit for the purpose of

or indirectly, (i) to purchase or carry any margin stock or to extend credit to
others for the purpose of purchasing or carrying any margin stock or (ii) for
the purpose of purchasing, carrying or trading in any securities under such
circumstances as to involve the Borrowers or any of their respective
Subsidiaries in a violation of Regulation X.

nor any of their respective Subsidiaries is subject to regulation under the
Public Utility Holding Company Act, as amended, the Investment Company Act of

such Person to incur Indebtedness is limited or its ability to consummate the
transactions contemplated by this Agreement or the other Loan Documents is
impaired.

Section 4.10 Disclosure. The schedules, documents, exhibits,
reports, certificates and other written statements and information furnished by
or on behalf of the Borrowers to the Bank Group do not contain any Material
misstatement of fact, or omit to state a Material fact necessary in order to
make the statements contained therein, in light of the circumstances under

ARTICLE VIII
THE ADMINISTRATIVE AGENT, THE
SYNDICATION AGENT AND THE ISSUING BANK

Section 8.01 Authorization and Action. Each Bank hereby
appoints and authorizes the Administrative Agent, the Syndication Agent and the
Issuing Bank to take such action in such capacity on such Bank's behalf and to
exercise such powers under this Agreement and the other

-50-
56
Loan Documents as are delegated to the Administrative Agent, the Syndication
Agent or the Issuing Bank by the terms hereof and thereof, together with such
powers as are reasonably incidental thereto. As to any matters not expressly
provided for by this Agreement (including, without limitation, enforcement or
collection of the Notes or of amounts owing under the other Loan Documents),
neither the Administrative Agent, the Syndication Agent nor the Issuing Bank
shall be required to exercise any discretion or take any action, but shall be
required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Majority Banks,
and such instructions shall be binding upon all Banks and any other holders of
Notes; provided, however, that neither the Administrative Agent, the
Syndication Agent nor the Issuing Bank shall be required to take any action
which exposes it to personal liability or which is contrary to the Loan
Documents or applicable law. Each of the Administrative Agent, the Syndication
Agent and the Issuing Bank is hereby expressly authorized on behalf of the
other members of the Bank Group, without hereby limiting any implied authority,
(a) to receive on behalf of each of the other members of the Bank Group any
payment of principal of or interest on the Loans outstanding hereunder, any
Letters of Credit and all other amounts accrued hereunder paid to such Persons,
and promptly to distribute to each other member of the Bank Group its proper
share of all payments so received; (b) to give notice within a reasonable time
on behalf of each other member of the Bank Group to the Borrowers of any
Default or Event of Default specified in this Agreement of which the
Administrative Agent has actual knowledge as provided in Section 8.09; (c) to
distribute to the other members of the Bank Group copies of all notices,
agreements and other material as provided for in this Agreement as received by
such Person; and (d) to distribute to the Borrowers any and all requests,
demands and approvals received by such Person from any other member of the Bank
Group. Nothing herein contained shall be construed to constitute the
Administrative Agent, the Syndication Agent or the Issuing Bank as a trustee
for any holder of the Notes or of a participation therein, nor to impose on the
Administrative Agent, the Syndication Agent or the Issuing Bank any duties or
obligations other than those expressly provided for in the Loan Documents.

Section 8.02 Reliance. None of the Administrative Agent, the
Syndication Agent, the Issuing Bank, their Affiliates and their respective
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in connection with this
Agreement, except for its or their own gross negligence or willful misconduct
(as determined by a court of competent jurisdiction by final and non-appealable
judgment). Without limitation of the generality of the foregoing, the
Administrative Agent, the Syndication Agent and the Issuing Bank: (a) may treat
the payee of any Note as the holder thereof until the Administrative Agent
receives and accepts an Assignment and Acceptance entered into by the Bank
which is the payee of such Note, as assignor, and an Eligible Assignee, as
assignee, as provided in Section 10.02; (b) may consult with legal counsel
(including counsel for the Borrowers), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any Bank and
shall not be responsible to any Bank for any statements, warranties or
representations (whether written or oral) made in or in connection with this
Agreement or the other Loan Documents; (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms,
covenants or conditions of this Agreement or the other Loan

-51-

Documents on the part of the Borrowers or any other Person or to inspect the
property (including the books and records) of the Borrowers or any other
Person; (e) shall not be responsible to any Bank for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of any
Loan Document, any collateral provided for therein, or any other instrument or
document furnished pursuant thereto; and (f) shall incur no liability under or
in respect of this Agreement by acting upon any notice, consent, certificate or
other instrument or writing (which may be by telecopier, telegram, cable or
telex) believed by it to be genuine and signed or sent by the proper party or
parties. None of the Administrative Agent, the Syndication Agent, the Issuing
Bank, their Affiliates and their respective directors, officers, employees or
agents shall have any responsibility to the Borrowers on account of the failure
or delay in performance or breach by any Bank of any of its obligations
hereunder or to any Bank on account of the failure of or delay in performance
or breach by any other Bank or any Borrower of any of its obligations hereunder
or in connection herewith; provided that the foregoing does not relieve the
Administrative Agent, the Syndication Agent or the Issuing Bank of any of its
respective obligations in its capacity as a Bank.

Section 8.03 Agents, Affiliates and Other Activities.
Without limiting the right of any other Bank to engage in any business
transactions with the Borrowers or any of their Affiliates, with respect to its
Commitment, the Loans made by it, the Notes issued to it and its interest in
the Outstanding Letters of Credit, the Administrative Agent and the Syndication
Agent shall each have the same rights and powers under this Agreement as any
other Bank and may exercise the same as though they were not such Agents; and
the term "Bank" or "Banks" shall, unless otherwise expressly indicated, include
said Person in its individual capacity. Each of said Agents, or any of their
Affiliates, may be engaged in, or may hereafter engage in, one or more loan,
Letter of Credit, leasing, derivative or other financing activities not the
subject of the Loan Documents (collectively, the "Other Financings") with the
Borrowers or any of their Affiliates, or may act as trustee on behalf of, or
depositary for, or otherwise engage in other business transactions with the
Borrowers or any of their Affiliates (all Other Financings and other such
business transactions being collectively, the "Other Activities") with no
responsibility to account therefor to the Banks. Without limiting the rights
and remedies of the Banks specifically set forth in the Loan Documents, no
other Bank shall have any interest in (a) any Other Activities, (b) any present
or future guarantee by or for the account of the Borrowers not contemplated or
included in the Loan Documents, (c) any present or future offset exercised by
said Agents in respect of any such Other Activities, (d) any present or future
Property taken as security for any such Other Activities or (e) any Property
now or hereafter in the possession or control of said Agents which may be or
become security for the obligations of the Borrowers under the Loan Documents
by reason of the general description of indebtedness secured, or of Property,
contained in any other agreements, documents or instruments related to such
Other Activities; provided, that if any payment in respect of such guarantees
or such Property or the proceeds thereof shall be applied to reduction of the
obligations evidenced hereunder and by the Notes, then each Bank shall be
entitled to share in such application according to its pro rata portion of such
obligations.

Section 8.04 Bank Credit Decision. Each Bank acknowledges
that it has, independently and without reliance upon any other member of the
Bank Group and based on the

-52-
58
financial statements referred to in Section 4.06 and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Bank also acknowledges that it
will, independently and without reliance upon any other member of the Bank
Group and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement.

Section 8.05 Indemnification. The Banks agree to indemnify
each of the Administrative Agent, the Syndication Agent and the Issuing Bank,
their Affiliates or any of their respective directors, officers, agents or
employees (to the extent not reimbursed by the Borrowers), ratably according to
its Commitment Percentage, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against any such Person in any way relating to or
arising out of this Agreement or the other Loan Documents or any action taken
or omitted by any such Person under this Agreement or the other Loan Documents,
provided, that no Bank shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Person's gross negligence or
willful misconduct (as determined by a court of competent jurisdiction by final
and non-appealable judgment). IT IS THE EXPRESS INTENTION OF THE PARTIES
HERETO THAT THE ADMINISTRATIVE AGENT, THE SYNDICATION AGENT, THE ISSUING BANK
AND THEIR AFFILIATES AND THEIR DIRECTORS, OFFICERS, AGENTS OR EMPLOYERS SHALL
BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
DISBURSEMENTS OF ANY KIND ARISING OUT OF OR RESULTING FROM THE ORDINARY
NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH PERSON. Neither the
Administrative Agent, the Syndication Agent nor the Issuing Bank shall be
required to do any act hereunder or under any other document or instrument
delivered hereunder or in connection herewith or take any action toward the
execution or enforcement of the agencies hereby created, or to prosecute or
defend any suit in respect of this Agreement or the Loan Documents or any
Collateral, unless indemnified to its satisfaction by the holders of the Notes
against loss, cost, liability, and expense. If any indemnity furnished to the
Administrative Agent, the Syndication Agent and the Issuing Bank for any
purpose is, in the opinion of such Person insufficient or becomes impaired,
such Person may call for additional indemnity and not commence or cease to do
the acts indemnified against until such additional indemnity is furnished.
Without limitation of the foregoing, each Bank agrees to reimburse the

GUARANTY

Section 9.01 Guaranty. (a) In consideration of, and in order
to induce the Banks to make Loans under this Agreement and to induce the
Issuing Bank to issue Letters of Credit under this Agreement, each Guarantor,
including each Borrower, hereby jointly, severally, unconditionally and
irrevocably, guarantees, as primary obligor, and not merely as surety, the
punctual payment and performance when due, whether at stated maturity, as an
installment, by required or optional prepayment or by demand, acceleration or
otherwise, of all Obligations of the Borrowers now or hereafter existing,
except as hereinafter provided. If any or all of the Obligations becomes due
and payable hereunder, the Guarantors jointly and severally unconditionally
promise to pay such Obligations to the Administrative Agent, or order, on
demand, together with any and all expenses (including reasonable counsel fees
and expenses) which may be incurred by the Bank Group in collecting any of the
Obligations and in connection with the protection, defense or enforcement of
any rights under this Agreement or any Loan Document; provided that
notwithstanding anything contained herein or in any of the Loan Documents to
the contrary, the maximum liability of each Guarantor hereunder shall never
exceed the maximum amount which said Guarantor could pay without having such
payment set aside as a fraudulent transfer or fraudulent conveyance or similar
action under the U.S. Bankruptcy Code or applicable state or foreign law,
provided further, each Guarantor shall be unconditionally required to pay all
amounts demanded of it hereunder prior to any determination of such maximum
liability and the recipient of such payment, if so required by a final
non-appealable order of a court of competent jurisdiction by final and
non-appealable judgment, shall then be liable for the refund of any excess
amounts. If any such rebate or refund is ever required, all other Guarantors
(and the Borrowers) shall be fully liable for the repayment thereof to the
maximum extent allowed by applicable law.

(b) Notwithstanding any provisions of Section 9.01(a),
the Guarantor, Xxxxx Xxxxxxxx, shall not guaranty the Tranche B Loan, nor shall
the Guarantors Saybolt International B.V.,

-56-
62
Saybolt Eastern Hemisphere B.V., X.X. Xxxxxxx & Co. S.A. or Saybolt van Duyn
Holding B.V. guaranty the Tranche A Loan.

Section 9.02 Guaranty Absolute. Subject to Section 9.01,
each of the Guarantors hereby unconditionally guarantees that the Obligations
will be paid strictly in accordance with the terms of this Agreement, the Notes
and the other Loan Documents, regardless of any law, regulation or order now or
hereafter in effect in any jurisdiction affecting any of such terms or the
rights of any member of the Bank Group with respect thereto. The liability of
each Guarantor under this Article IX shall constitute a guaranty of payment and
not of collection and shall be absolute and unconditional irrespective of, and
each Guarantor waives any and all defenses that may arise out of, any of the
following: (a) any lack of validity or enforceability of the Obligations, this
Agreement, the Notes, or any other Loan Document or any other agreement,
security document or instrument relating hereto or thereto; (b) any extension,
renewal, modification, settlement, compromise, waiver or release or any change
in the time, manner or place of payment of, or in any other term of, all or any
of the Obligations, or any other amendment or waiver of or any consent to
departure from this Agreement, the Notes or any other Loan Document or any
other agreement or instrument relating thereto or executed in connection
therewith or pursuant thereto; (c) any taking, exchange, release or non-
perfection of any Collateral, or any release or amendment or waiver of or
consent to departure from any other Guaranty Agreement, for all or any of the
Obligations; (d) any manner of application of collateral, or proceeds thereof,
to all or any of the Obligations, or any manner of sale or other disposition of
any Collateral for all or any of the Obligations or any other assets of the
Borrowers or any other Person (including any other Guarantor); (e) any change,
restructuring or termination of the corporate structure or existence of any of
the Borrowers or any other Person; (f) any manner of application of payments on
the Obligations, whether at the direction of any of the Borrowers or any other
Person; (g) any other similar circumstances which might otherwise constitute a
defense available to, or a discharge of, any of the Borrowers or any other
Person (including any other Guarantor) of all or part of the Obligations; or
(h) any of said Guarantor's obligations as a Borrower hereunder in respect of
any other Loan. The obligations of the Guarantors under this guaranty shall
not be subject to reduction, termination or other impairment by reason of any
setoff, recoupment, counterclaim or defense or for any other reason. This
guaranty is to be in addition to and is not to prejudice or be prejudiced by
any other securities or guaranties (including any guaranty signed by any other
Guarantor) which any member of the Bank Group may now or hereafter hold from or
on account of any of the Borrowers and is to be binding on each Guarantor as a
continuing security notwithstanding any payments from time to time made to any
member of the Bank Group or any settlement of account or disability or
incapacity affecting such Guarantor or any other thing whatsoever.

Section 9.03 Waiver. Each Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Obligations and this Agreement and any liability to which this Agreement
applies or may apply, and waives presentment, demand of payment, notice of
intent to accelerate, notice of acceleration, notice of dishonor or nonpayment,
and any requirement that any member of the Bank Group institute suit,
collection proceedings or take any other action to collect the Obligations,
including any requirement that any member of the Bank

-57-
63
Group protect, secure, perfect or insure any security interest or Lien against
any Property subject thereto or exhaust any right or take any action against
the Borrowers or any other Person (including the other Guarantor) or any
Collateral (it being the intention of the Bank Group and each Guarantor that
the obligations of such Guarantor under this Article IX are to be a guaranty of
payment and not of collection) or that any Borrower or any other Person
(including the any other Guarantor) be joined in any action hereunder. Each
Guarantor hereby expressly waives, to the extent it is located in Texas or
otherwise entitled to the benefits thereof, each and every right to which it
may be entitled by virtue of the suretyship laws of the State of Texas,
including, without limitation, any and all rights it may have pursuant to Rule
31 or Rule 32, Texas Rules of Civil Procedure, Section 17.001 of the Texas
Civil Practice and Remedies Code and Chapter 34 of the Texas Business and
Commerce Code. Each Guarantor hereby waives marshaling of assets and
liabilities, sale in inverse order of alienation, notice by any member of the
Bank Group of the creation of any Indebtedness or liability to which it applies
or may apply, any amounts received by any member of the Bank Group, notice of
disposition or substitution of Collateral and of the creation, advancement,
increase, existence, extension, renewal, rearrangement and/or modification of
the Obligations.

Section 9.04 Subrogation. Subject to Section 9.06, each
Guarantor hereby irrevocably agrees that until the Obligations have been paid
in full and all the Commitments have been canceled, it will not exercise any
rights to which it may be entitled, by operation of law or otherwise, upon
making any payment hereunder (a) to be subrogated to the rights of any member
of the Bank Group against any of the Borrowers with respect to such payment,
(b) to be reimbursed, indemnified or exonerated by any of the Borrowers in
respect thereof, (c) to receive any payment, in the nature of contribution or
for any other reason, from any of the Borrowers with respect to such payment,
(d) to enforce any remedy which such Guarantor now has or may hereafter have
against the Borrowers or (e) to receive any benefit of, or right to participate
in, any security now or hereafter held by or for the benefit of any member of
the Bank Group. Each Guarantor agrees that if any amount shall be paid to
such Guarantor on account of any such rights at any time while such rights are
restricted pursuant to the preceding sentence, such amount shall be held in
trust for the benefit of the Bank Group and shall forthwith be paid to the
Administrative Agent to be credited and applied upon the Obligations, whether
matured or unmatured, in accordance with the terms of this Agreement.

Section 9.05 Continuing Guaranty. This guaranty is a
continuing guaranty and shall remain in full force and effect until payment in
full of the Obligations.

Section 9.06 Effect of Bankruptcy Proceeding. This guaranty
shall continue to be effective, or be automatically reinstated, as the case may
be, if at any time payment, in whole or in part, of any of the Obligations is
rescinded or must otherwise be restored or returned by any member of the Bank
Group upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of any of the Borrowers, any Guarantor or any other Person, or
upon or as a result of the appointment of a custodian, receiver, trustee or
other officer with similar powers with respect to any of the Borrowers, any
Guarantor or any other Person, or any substantial part of their Property, or
otherwise, all as though such payments had not been made. If an Event of
Default shall at any time have

-58-
64
occurred and be continuing and declaration of such Event of Default shall at
such time be prevented by reason of the pendency against any of the Borrowers
of a case or proceeding under a bankruptcy or insolvency law, each Guarantor
agrees that, for purposes of this Agreement and its obligations hereunder, the
Obligations shall be deemed to have been accelerated with the same effect as if
the Obligations had been accelerated in accordance with the terms hereof, and
each Guarantor shall forthwith pay the Obligations specified by the
Administrative Agent to be paid hereunder without further notice or demand.

Section 9.07 Further Responsibilities. It is not necessary
for any member of the Bank Group to inquire into the capacity or powers of the
Borrowers or the officers, directors, partners or agents acting or purporting
to act on their behalf, and any Obligations made or created in reliance upon
the professed exercise of such powers shall be guaranteed hereunder. Each
Guarantor assumes all responsibility for being and keeping itself informed of
the other Borrowers' financial condition and assets, and of all other
circumstances bearing upon the risk of nonpayment of the Obligations and the
nature, scope and extent of the risks which each Guarantor assumes and incurs
hereunder, and agrees that no member of the Bank Group shall have any duty to
advise either Guarantor of information known to them regarding such
circumstances or risks.

Section 9.08 Subordination. Each Borrower and Guarantor
hereby subordinates all indebtedness owing to it from any other Borrower or
Guarantor to the Obligations, and agrees that upon the occurrence and during
the continuance of a Default or an Event of Default, it shall not accept any
payment on the same until payment in full of the Obligations, and shall in no
circumstance whatsoever attempt to set off or reduce any obligations hereunder
because of such Indebtedness.

members of the Bank Group shall continue to deal solely and directly with such

Section 10.13 Limitation on Interest. Each provision in this
Agreement and each other Loan Document is expressly limited so that in no event
whatsoever shall the amount paid, or otherwise agreed to be paid, by a Borrower
for the use, forbearance or detention of the money to be loaned under this
Agreement or any other Loan Document or otherwise (including any sums paid as
required by any covenant or obligation contained herein or in any other Loan
Document which is for the use, forbearance or detention of such money), exceed
that amount of money which would cause the effective rate of interest to exceed
the Highest Lawful Rate, and all amounts owed under this Agreement and each
other Loan Document shall be held to be subject to reduction to the effect that
such amounts so paid or agreed to be paid which are for the use, forbearance or
detention of money under this Agreement or such Loan Document shall in no event
exceed that amount of money which would cause the effective rate of interest to
exceed the Highest Lawful Rate. To the extent that the Highest Lawful Rate
applicable to a Bank is at any time determined by Texas law, such rate shall be
the "indicated rate ceiling" described in Section (a)(1) of Article 1.04 of
Chapter 1, Subtitle 1, Title 79, of the Revised Civil Statutes of Texas, 1925,
as amended; provided, to the extent permitted by such Article, the Banks from
time to time by notice from the Administrative Agent to the Borrowers may
revise the aforesaid election of such interest rate ceiling as such ceiling
affects the then-current or future balances of the Loans outstanding under the
Notes. Notwithstanding any provision in this Agreement or any other Loan
Document to the contrary, if the maturity of the Notes or the obligations in
respect of the other Loan Documents are accelerated for any reason, or in the
event of prepayment of all or any portion of the Notes or the obligations in
respect of the other Loan Documents by a Borrower or in any other event, earned
interest on the Loans and such other obligations of such Borrower may never
exceed the maximum amount permitted by applicable law, and any unearned
interest otherwise payable under the Notes or the obligations in respect of the
other Loan Documents that is in excess of the maximum amount permitted by
applicable law shall be canceled automatically as of the date of such
acceleration or prepayment or other such event and, if theretofore paid, shall
be credited on the principal of the relevant Notes or, if the principal of the
relevant Notes has been paid in full, held as collateral for any contingent or
unmatured obligation

-68-
74
of such Borrower, or, if there are no contingent or unmatured obligations of
such Borrower then outstanding, refunded to such Borrower. In determining
whether or not the interest paid or payable, under any specific contingency,
exceeds the Highest Lawful Rate, the Borrowers and the Banks shall, to the
maximum extent permitted by applicable law, amortize, prorate, allocate and
spread, in equal parts during the period of the actual term of this Agreement,
all interest at any time contracted for, charged, received or reserved in
connection with this Agreement. Chapter 15, Subtitle 3, Title 79, of the
Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loans
and revolving triparty accounts), shall not apply to this Agreement or the
Notes or the transactions contemplated hereby.

Section 10.14 Indemnification. Each Borrower agrees to
indemnify, defend and hold each member of the Bank Group, their Affiliates and
their officers, employees, agents, directors, shareholders and Affiliates
(collectively, "Indemnified Persons") harmless from and against any and all
loss, liability, damage, judgment, claim, deficiency or expense (including
interest, penalties, reasonable attorneys' fees and amounts paid in settlement)
incurred by or asserted against any Indemnified Person arising out of, in any
way connected with, or as a result of (i) the execution and delivery of this
Agreement and the other Loan Documents, the performance by the parties hereto
and thereto of its obligations hereunder and thereunder (including but not
limited to the making of the Commitments of each Bank) and consummation of the
transactions contemplated hereby and thereby, (ii) the actual or proposed use
of the Letters of Credit or the proceeds of the Loans, (iii) any violation by a
Borrower or any of its Subsidiaries of any Requirement of Law, including but
not limited to Environmental Laws, (iv) ownership by the Bank Group of any
Property following foreclosure under the Security Documents, to the extent such
losses, liabilities, damages, judgments, claims, deficiencies or expenses arise
out of or result from the presence, disposal or release of any hazardous
materials or solid waste in, on or under such property during the period owned,
leased or operated by a Borrower or any of its Subsidiaries, including, without
limitation, losses, liabilities, damages, judgments, claims, deficiencies or
expenses which are imposed under Environmental Laws upon Persons by virtue of
their ownership, (v) any member of the Bank Group being deemed an operator of
any such real or personal property in circumstances in which no member of the
Bank Group is generally operating or generally exercising control over such
Property, to the extent such losses, liabilities, damages, judgments, claims,
deficiencies or expenses arise out of or result from any hazardous materials or
solid waste located in, on or under such property or (vi) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnified Person is a party thereto; provided that such
indemnity shall not apply to any such losses, claims, damages, liabilities or
related expenses that are determined by a court of competent jurisdiction by
final and non-appealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnified Person. WITHOUT LIMITING ANY PROVISION
OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, IT IS THE EXPRESS
INTENTION OF THE BORROWERS THAT EACH INDEMNIFIED PERSON SHALL BE INDEMNIFIED
AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS,
DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM
THE ORDINARY NEGLIGENCE (WHETHER SOLE, CONCURRENT OR CONTRIBUTORY) OF SUCH
INDEMNIFIED

-69-
75
PERSON. THE OBLIGATIONS OF THE BORROWERS UNDER THIS SECTION 10.14 SHALL
SURVIVE THE TERMINATION OF THIS AGREEMENT.

Section 10.15 Confidentiality. In the event that a Borrower
or any of its Subsidiaries provides any member of the Bank Group with written
confidential information belonging to such Borrower or any of its Subsidiaries,
that has been identified in writing at the time of delivery as "confidential",
each member of the Bank Group severally agrees to thereafter maintain such
information in confidence in accordance with the standards of care and
diligence that each utilizes in maintaining its own confidential information.
This obligation of confidence shall not apply to such portions of the
information which (i) are in the public domain, (ii) hereafter become part of
the public domain, (iii) are previously known by the Bank Group from some
source other than a Borrower, (iv) are hereafter obtained by or available to
any member of the Bank Group from a third party who owes no obligation of
confidence to the Borrowers with respect to such information or through any
other means, (vi) are disclosed with a Borrower's consent, (vii) must be
disclosed either pursuant to any Requirements of Law or to Persons regulating
the activities of any member of the Bank Group, or (viii) as may be required by
law or regulation or order of any Governmental Authority in any judicial,
arbitration or governmental proceeding. Further, any member of the Bank Group
may disclose any such information to any other Bank, any consultants, any
independent certified public accountants, any legal counsel employed by such
Person in connection with this Agreement or any other Loan Document, including
without limitation, the enforcement or exercise of all rights and remedies
thereunder, or any assignee or participant (including prospective assignees and
participants) in the Loans; provided, however, that the member of the Bank
Group disclosing such information imposes on the Person to whom such
information is disclosed the same obligation to maintain the confidentiality of
such information as is imposed upon it hereunder. Notwithstanding anything to
the contrary provided herein, this obligation of confidence shall cease three
(3) years from the date the information was furnished, unless such Borrower
requests, in writing at least thirty (30) days prior to the expiration of such
three year period, that the Bank Group maintain the confidentiality of such
information for an additional three year period. Each Borrower waives any and
all other rights it may have to confidentiality as against the Bank Group
arising by contract, agreement, statute or law except as expressly stated in
this Section 10.15.

Section 10.16 Judgment. (a) Rate of Exchange. If, for the
purpose of obtaining judgment in any court, it is necessary to convert a sum
due under any Loan Document in another currency into Dollars or into a Foreign
Currency, as the case may be, the parties hereto agree, to the fullest extent
that they may effectively do so, that the rate of exchange used shall be that
at which, in accordance with normal banking procedures, a Bank could purchase
such other currency with Dollars or with such Foreign Currency, as the case may
be, in New York City, New York at the close of business on the Business Day
immediately preceding the day on which final judgment is given, together with
any premiums and costs of exchange payable in connection with such purchase.

(b) Indemnity. The obligation of each Borrower in
respect of any sum due from it to the Administrative Agent or any Bank under
any Loan Document shall, notwithstanding any judgment in a currency other than
Dollars or a Foreign Currency, as the case may be, be discharged

-70-
76
only to the extent that on the Business Day next succeeding receipt by the
Administrative Agent or such Bank of any sum adjudged to be so due in such
other currency, the Administrative Agent or such Bank may, in accordance with
normal banking procedures, purchase Dollars or such Foreign Currency, as the
case may be, with such other currency. If the Dollars or such Foreign Currency
so purchased are less than the sum originally due to such Administrative Agent
or such Bank in Dollars or in such Foreign Currency, each Borrower agrees, as a
separate obligation and notwithstanding any such judgment, to indemnify the
Administrative Agent or such Bank against such loss, and if the Dollars or such
Foreign Currency so purchased exceed the sum originally due to the
Administrative Agent or any Bank in Dollars or in such Foreign Currency, as the
case may be, the Administrative Agent or such Bank agrees to remit to such
Borrower such excess.

Section 10.17 Final Agreement of the Parties. THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO ORAL AGREEMENTS BETWEEN THE
PARTIES.

-71-
77

Agreement to be executed by its officers thereunto duly authorized as of the
