                   SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

     2.1 Commitments. (a) Subject to the terms and conditions hereof, each
Lender severally agrees to make revolving credit loans in Euros ("Euro Loans")
or in any Alternate Currency (including the Euro Loans, the "Loans") to the
Borrowers from time to time during the Commitment Period in an aggregate Euro or
Euro Equivalent principal amount for all Borrowers at any one time outstanding
which does not exceed the amount of such Lender's Commitment. No Borrower shall
request and no Lender shall be required to make any Loan if, after making such
Loan, the Total Loans would exceed the Total Commitments then in effect. During
the Commitment Period the Borrowers may use the Commitments by borrowing,
prepaying the Loans in whole or in part, and reborrowing, all in accordance with
the terms and conditions hereof.

     2.2 Procedure for Borrowing. Any Borrower may borrow Loans in Euros and
Alternate Currencies during the Commitment Period on any Business Day, provided
that the relevant Borrower shall give the Administrative Agent irrevocable
notice (which notice must be received by the Administrative Agent prior to 10:00
A.M., London time, three Business Days prior to the requested Borrowing Date),
specifying (i) the requested Borrowing Date, (ii) the

<PAGE>
                                                                              18

respective amounts of each Loan in each currency and (iii) the respective
lengths of the initial Interest Period therefor. Each Loan under the Commitments
shall be in an amount equal to (w) in the case of Euro Loans, (euro)5,000,000 or
a whole multiple of (euro)1,000,000 in excess thereof, (x) in the case of
Sterling Loans, (pound)5,000,000 or a whole multiple of (pound)500,000 in excess
thereof, (y) in the case of Dollar Loans, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof and (z) in the case of Loans denominated in any
other Alternate Currency, in an amount of which the Euro Equivalent shall be
approximately (euro)5,000,000 or a whole multiple of (euro)1,000,000 in excess
thereof. Upon receipt of any such notice from any Borrower, the Administrative
Agent shall promptly notify each Lender thereof. Each Lender will make the
amount of its pro rata share of each borrowing available to the Administrative
Agent for the account of the relevant Borrower at the Funding Office prior to
12:00 Noon, London time, or 3:00 p.m., London time in the case of Dollar Loans,
in each case, on the Borrowing Date requested by such Borrower in funds
immediately available in Euros or the relevant Alternate Currency to the
Administrative Agent. Such borrowing will then be made available to the relevant
Borrower by the Administrative Agent crediting the account of such Borrower on
the books of such Office with the aggregate of the amounts made available to the
Administrative Agent by the Lenders and in like funds as received by the
Administrative Agent or by wire transfer of such amounts to an account
designated in writing by such Borrower to the Administrative Agent in connection
with the relevant borrowing.

     2.3 Fees. (a) Thermo Luxembourg agrees to pay to the Administrative Agent
for the account of each Lender a commitment fee (a "Commitment Fee") in Euros,
which shall accrue at the Commitment Fee Rate on the average daily unused
portion of the Commitment of such Lender during the period from and including
the date hereof to but excluding the date on which such Commitment terminates.
Accrued Commitment Fees shall be payable quarterly in arrears on each Fee
Payment Date.

     (b) Thermo Luxembourg agrees to pay to the Administrative Agent the fees in
the amounts and on the dates as set forth in the Fee Letter, dated as of June 2,
2005, between Thermo Luxembourg and the Administrative Agent, and in any other
fee agreements between Thermo Luxembourg and the Administrative executed after
the date of this Agreement, and to perform any other obligations contained
therein.

     2.4 Optional Termination or Reduction of Commitments. Thermo Luxembourg
shall have the right upon not less than three Business Days' notice to the
Administrative Agent, to terminate the Commitments or, from time to time, to
reduce the amount of the Commitments; provided that no such termination or
reduction of Commitments shall be permitted if, after giving effect thereto and
to any prepayments of the Loans, the Total Loans would exceed the Total
Commitments. Any such reduction shall be in an amount equal to (euro)10,000,000,
or an integral multiple of (euro)1,000,000 in excess thereof, and shall reduce
permanently the Commitments then in effect.

     2.5 Optional Prepayments. Any Borrower may at any time and from time to
time prepay the Loans, in whole or in part, without premium or penalty, upon
irrevocable notice delivered to the Administrative Agent not later than 10:00
A.M., London time, three Business Days prior to the date of prepayment, which
notice shall specify the date and amount of prepayment and, if such prepayment
is of Alternate

<PAGE>
                                                                              19

Currency Loans, the applicable Alternate Currency; provided, that if a Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, the relevant Borrower shall also pay any amounts owing pursuant to
Section 2.16. Upon receipt of any such notice the Administrative Agent shall
promptly notify each Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified therein,
together with accrued interest to such date on the amount prepaid. Partial
prepayments shall be in the principal amount of (w) (euro)5,000,000 or a whole
multiple of (euro)1,000,000 in excess thereof, in the case of Euro Loans, (x)
(pound)5,000,000 or a whole multiple of (pound)500,000 in excess thereof, in the
case of Sterling Loans, (y) $5,000,000 or a whole multiple of $1,000,000 in
excess thereof, in the case of Dollar Loans, and (z) an amount of which the Euro
Equivalent shall be approximately (euro)5,000,000 or a whole multiple of
(euro)1,000,000 in excess thereof, in the case of other Alternate Currency
Loans.

     2.6 Mandatory Prepayments. If, on any date, the Total Loans outstanding on
such date exceed 102% of the Total Commitments in effect on such date, the
Borrowers shall, without notice or demand, promptly (but in any event, within
three Business Days of such date) prepay such outstanding Loans in an aggregate
principal amount such that, after giving effect thereto, the Total Loans do not
exceed the Total Commitments. Any amounts prepaid pursuant to this Section shall
be accompanied by interest accrued to the date of such prepayment on the
principal so prepaid and any amounts payable under Section 2.16 in connection
therewith.

     2.7 Continuation Options. Any Loan denominated in any currency may be
continued in such currency upon the expiration of the then current Interest
Period with respect thereto by the relevant Borrower giving irrevocable notice
to the Administrative Agent, in accordance with the applicable provisions of the
term "Interest Period" set forth in Section 1.1, of the length of the next
Interest Period to be applicable to such Loans, provided that if the relevant
Borrower shall fail to give any required notice of continuation of a Loan, such
Loan shall be automatically continued in such currency for an Interest Period of
one month. Upon receipt of any such notice the Administrative Agent shall
promptly notify the Lenders thereof.

     2.8 Limitations on Tranches. Notwithstanding anything to the contrary in
this Agreement, all borrowings and continuations of Loans and all selections of
Interest Periods shall be in such amounts and be made pursuant to such elections
so that no more than ten Tranches shall be outstanding at any one time.

     2.9 Repayment of Loans. Each Borrower hereby unconditionally promises to
pay to each Lender on the Termination Date (or such earlier date as the Loans
become due and payable pursuant to Section 7), the unpaid principal amount of
each Loan made to such Borrower by such Lender. Each Borrower hereby further
agrees to pay interest in immediately available funds at the office of the
Administrative Agent on the unpaid principal amount of such Loans from time to
time from the date hereof until payment in full thereof at the rates per annum,
and on the dates, set forth in Section 2.10.
<PAGE>
                                                                              20

     2.10 Interest Rates and Payment Dates. (a) Each Loan shall bear interest
for each day during each Interest Period with respect thereto at a rate per
annum equal to (i) the LIBOR Rate determined for such day plus (ii) the Margin
plus (iii) any Mandatory Cost incurred by such Lender in respect of such Loans
from time to time.

     (b) (i) If all or a portion of the principal amount of any Loan shall not
be paid when due (whether at the stated maturity, by acceleration or otherwise),
such overdue amount shall bear interest at a rate per annum equal to the rate
that would otherwise be applicable thereto pursuant to the foregoing provisions
of this Section plus 2% and (ii) if all or a portion of any interest payable on
any Loan or any commitment fee or other amount payable hereunder shall not be
paid when due (whether at the stated maturity, by acceleration or otherwise),
such overdue amount shall bear interest at a rate per annum equal to the highest
rate then applicable under this Agreement to Loans denominated in the currency
in which such amount is payable hereunder plus 2%, in each case, with respect to
clauses (i) and (ii) above, from the date of such non-payment until such amount
is paid in full (before as well as after judgment).

     (c) Interest shall be payable in arrears on each Interest Payment Date,
provided that interest accruing pursuant to paragraph (c) of this Section shall
be payable from time to time on demand.

     2.11 Computation of Interest and Fees. (a) Interest and fees payable
pursuant hereto shall be calculated on the basis of a 360-day year for the
actual days elapsed, except that, with respect to Sterling Loans, interest shall
be calculated on the basis of a 365-day year for actual days elapsed. The
Administrative Agent shall as soon as practicable notify the relevant Borrower
and the Lenders of each determination of a LIBOR Rate. Any change in the
interest rate on a Loan resulting from a change in the Margin shall become
effective as of the opening of business on the day on which such change becomes
effective. The Administrative Agent shall as soon as practicable notify the
relevant Borrower and the Lenders of the effective date and the amount of each
such change in interest rate.

     (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the relevant Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of any Borrower, deliver to such
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.10(a).

     2.12 Inability to Determine Interest Rate. If prior to the first day of any
Interest Period:

     (a) the Administrative Agent shall have determined (which determination
shall be conclusive and binding upon the Borrowers) that, by reason of
circumstances affecting the relevant market, adequate and reasonable means do
not exist for ascertaining the LIBOR Rate for Loans in Euros or one or more
Alternate Currencies for such Interest Period,

     (b) the Administrative Agent shall have received notice from the Required
Lenders that the LIBOR Rate determined or to be determined for Loans in Euros or
one or more Alternate Currencies for such Interest Period will not adequately
and fairly reflect the cost to the

<PAGE>
                                                                              21

Required Lenders (as conclusively certified by such Lenders) of making or
maintaining such Loans during such Interest Period, or

     (c) the Administrative Agent determines (which determination shall be
conclusive and binding upon the Borrowers) that deposits in the applicable
currency are not generally available, or cannot be obtained by the Lenders, in
the applicable market (any currency affected by the circumstances described in
clause (a), (b) or (c) is referred to as an "Affected Currency"),

then the Administrative Agent shall give telecopy or telephonic notice thereof
to the Borrowers and the Lenders as soon as practicable thereafter. If such
notice is given, then (i) any such Loans in an Affected Currency requested to be
made on the first day of such Interest Period shall not be made, (ii) any
outstanding Loans in an Affected Currency shall be due and payable on the last
day of the then-current Interest Period, and (iii) until such notice has been
withdrawn by the Administrative Agent, no further Loans in an Affected Currency
shall be made or continued as such. Notwithstanding the foregoing, as promptly
as practicable but in no event later than three Business Days after the giving
of the required notice by the Administrative Agent with respect to such
circumstances, the Administrative Agent (in consultation with the Lenders) shall
negotiate with the Borrowers in good faith in order to ascertain whether a
substitute interest rate (a "Substitute Rate") may be agreed upon for the
maintaining of Loans in the Affected Currency. If a Substitute Rate is agreed
upon by the Borrowers and all the Lenders, such Substitute Rate shall apply. If
a Substitute Rate is not so agreed upon by the Borrowers and all the Lenders
within such time, each Lender's Loans in the Affected Currency shall thereafter
bear interest at a rate equal to the sum of (i) the rate certified by such
Lender to be its costs of funds (from such sources as it may reasonably select
out of those sources then available to it) for such Loans, plus (ii) the Margin
plus (iii), any Mandatory Cost incurred by such Lender in respect of such Loans
from time to time.

     2.13 Pro Rata Treatment and Payments. (a) Each borrowing by any Borrower
from the Lenders hereunder, each payment by any Borrower on account of any
commitment fee and any reduction of the Commitments of the Lenders shall be made
pro rata according to the respective Loan Percentages of the Lenders.

     (b) Each payment (including each prepayment) by any Borrower on account of
principal of and interest on the Loans shall be made pro rata according to the
respective outstanding principal amounts of the Loans then held by the Lenders.

     (c) All payments (including prepayments) to be made by any Borrower,
whether on account of principal, interest, fees or otherwise, shall be made
without setoff or counterclaim and shall be made prior to 12:00 Noon, London
time, on the due date thereof to the Administrative Agent, for the account of
the Lenders, at its Funding Office, in immediately available funds. Except as
otherwise specified in this Agreement, amounts owing hereunder on account of
principal and interest on Loans shall be paid in the currency in which such Loan
was borrowed, and amounts owing hereunder on account of fees shall be paid in
Euros. The Administrative Agent shall distribute such payments to the Lenders
promptly upon receipt in like funds as received. If any payment on a Loan
becomes due and payable on a day other than a Business Day, the maturity thereof
shall be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in

<PAGE>
                                                                              22

which event such payment shall be made on the immediately preceding Business
Day. In the case of any extension of any payment of principal pursuant to the
preceding two sentences, interest thereon shall be payable at the then
applicable rate during such extension.

     (d) Unless the Administrative Agent shall have been notified in writing by
any Lender prior to a borrowing that such Lender will not make the amount that
would constitute its share of such borrowing available to the Administrative
Agent, the Administrative Agent may assume that such Lender is making such
amount available to the Administrative Agent, and the Administrative Agent may,
in reliance upon such assumption, make available to the relevant Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate determined by the Administrative Agent to be the cost to it of funding such
amount until such Lender makes such amount immediately available to the
Administrative Agent. A certificate of the Administrative Agent submitted to any
Lender with respect to any amounts owing under this paragraph shall be
conclusive in the absence of manifest error. If such Lender's share of such
borrowing is not made available to the Administrative Agent by such Lender
within three Business Days after such Borrowing Date, the Administrative Agent
shall also be entitled to recover such amount with interest thereon at a rate
determined by the Administrative Agent to be the sum of (x) the cost to it of
funding such amount plus (y) the Margin, on demand, from the relevant Borrower.
The failure or refusal of any Lender to make available to the Administrative
Agent such Lender's share of such borrowing shall not relieve any other Lender
from its several obligation hereunder to make available to the Administrative
Agent the amount of such other Lender's share of such borrowing. Nothing herein
shall be deemed to limit the rights of any Borrower against any Lender that has
failed or refused to make available such Lender's share of any borrowing.

     (e) Unless the Administrative Agent shall have been notified in writing by
any Borrower prior to the date of any payment due to be made by such Borrower
hereunder that such Borrower will not make such payment to the Administrative
Agent, the Administrative Agent may assume that such Borrower is making such
payment, and the Administrative Agent may, but shall not be required to, in
reliance upon such assumption, make available to the Lenders their respective
pro rata shares of a corresponding amount. If such payment is not made to the
Administrative Agent by the relevant Borrower within three Business Days after
such due date, the Administrative Agent shall be entitled to recover, on demand,
from each Lender to which any amount which was made available pursuant to the
preceding sentence, such amount with interest thereon at a rate per annum
determined by the Administrative Agent to be the cost to it of funding such
amount. Nothing herein shall be deemed to limit the rights of the Administrative
Agent or any Lender against the relevant Borrower with respect to such payment.

     2.14 Requirements of Law. (a) If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof by any
Governmental Authority charged with the interpretation or administration thereof
or compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made, in
each case, subsequent to the date hereof:

          (i) shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement or any Loan made by it, or change the basis of
     taxation of
<PAGE>
                                                                              23

     payments to such Lender in respect thereof (except for Non-Excluded Taxes
     covered by Section 2.15 and changes in the rate of tax on the overall net
     income of such Lender);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender that is not otherwise included in the determination
     of the LIBOR Rate; or

          (iii) shall impose on such Lender any other condition relating to
     funding of assets that would include the Loans or the income or earnings in
     respect thereof (except for Non-Excluded Taxes covered by Section 2.15 and
     changes in the rate of tax on the overall net income of such Lender);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount that such Lender reasonably deems to be material, of making,
continuing or maintaining Loans, or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, the relevant Borrower shall, promptly
after its receipt of a notice with respect thereto in accordance with Section
2.14(d), pay such Lender, upon its demand, any additional amounts necessary to
compensate such Lender for such increased cost or reduced amount receivable.

     (b) If any Lender shall have reasonably determined that the adoption of or
any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof by a Governmental Authority charged with
the interpretation or administration thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made, in each case, subsequent to the date hereof shall have the
effect of reducing the rate of return on such Lender's or such corporation's
capital as a consequence of its obligations hereunder to a level below that
which such Lender or such corporation could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's or such
corporation's policies with respect to capital adequacy) by an amount reasonably
deemed by such Lender to be material, then from time to time, after such Lender
has provided written notice in accordance with Section 2.14(d) to the relevant
Borrower requesting compensation for such reduction under this paragraph, the
relevant Borrower shall pay to such Lender such additional amount or amounts as
will compensate such Lender or such corporation for such reduction.

     (c) If any Governmental Authority of the jurisdiction from which Euros or
any Alternate Currency is issued (or any other jurisdiction in which the funding
operations of any Lender shall be conducted with respect to such currency) shall
have in effect any reserve, liquid asset or similar requirement with respect to
any category of deposits or liabilities customarily used to fund loans in such
currency, or by reference to which interest rates applicable to loans in such
currency are determined (other than any such requirement included in the
computation of Mandatory Cost), and the result of such requirement shall be to
increase the cost to such Lender of making or maintaining any Loan in such
currency, and such Lender shall deliver to the relevant Borrower a written
notice in accordance with Section 2.14(d) requesting compensation for such
additional cost under this paragraph, then the relevant Borrower will pay to
such Lender

<PAGE>
                                                                              24

on each Interest Payment Date with respect to each affected Loan an amount that
will compensate such Lender for such additional cost.

     (d) If any Lender becomes entitled to claim any additional amounts,
compensation or additional costs pursuant to this Section, it shall deliver a
written notice in accordance with this paragraph to the relevant Borrower (with
a copy to the Administrative Agent) requesting such additional amounts,
compensation or additional costs and notifying the relevant Borrower of the
event by reason of which it has become so entitled. Such Lender agrees to use
reasonable efforts to deliver such notice promptly following the time at which
it becomes aware of the event giving rise to such additional amounts,
compensation or additional cost payable (provided that, except as provided below
in this paragraph, the failure by such Lender to give such notice promptly shall
not adversely affect any of its rights hereunder). A certificate as to any
additional amounts, compensation or additional costs payable to any Lender
pursuant to this Section 2.14 submitted by any Lender to any Borrower (with a
copy to the Administrative Agent) shall be conclusive in the absence of manifest
error. Notwithstanding anything to the contrary contained in paragraphs (a), (b)
and (c) above, no Borrower shall be required to compensate a Lender pursuant to
such paragraphs for any amounts incurred more than three months prior to the
date that such Lender notifies such Borrower of such Lender's intention to claim
compensation therefor; and provided further that, if the circumstances giving
rise to such claim have a retroactive effect, then such three-month period shall
be extended to include the period of such retroactive effect. The obligations of
each Borrower pursuant to this Section 2.14 shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

     (e) Notwithstanding any other provision of this Agreement, if (x) the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof by a Governmental Authority charged with the interpretation
or administration thereof or compliance by any Lender with any request or
directive (whether or not, in each case, having the force of law) from any
central bank or other Governmental Authority made subsequent to the date hereof
shall make it unlawful for any Lender to make or maintain any Alternate Currency
Loan or to give effect to its obligations as contemplated hereby with respect to
any Alternate Currency Loan, or (y) there shall have occurred any change in
national or international financial, political or economic conditions (including
the imposition of or any change in exchange controls, but excluding conditions
otherwise covered by this Section 2.14) which would make it impracticable for
any Lender to make or maintain Loans denominated in the relevant Alternate
Currency after the date hereof to, or for the account of, any Borrower, then, by
written notice to each Borrower and to the Administrative Agent:

          (i) such Lender may declare that Loans (in the affected Alternate
     Currency or Currencies) will not thereafter (for the duration of such
     unlawfulness or change in conditions) be made by such Lender or Lenders
     hereunder (or be continued for additional Interest Periods), whereupon any
     request for a Loan (in the affected Alternate Currency or Currencies) or to
     continue a Loan (in the affected Alternate Currency or Currencies), as the
     case may be, for an additional Interest Period shall, as to such Lender
     only, be of no force and effect, unless such declaration shall be
     subsequently withdrawn; and
<PAGE>
                                                                              25

          (ii) such Lender may require that all outstanding Loans (in the
     affected Alternate Currency or Currencies), made by it be converted to Euro
     Loans (unless repaid by the relevant Borrower), in which event all such
     Loans (in the affected Alternate Currency or Currencies) shall be converted
     to Euro Loans as of the effective date of such notice as provided in
     paragraph (f) below and at the Exchange Rate on the date of such conversion
     or, at the option of the relevant Borrower, repaid on the last day of the
     then current Interest Period with respect thereto.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal made thereafter that would otherwise have
been applied to repay the converted Alternate Currency Loans of such Lender
shall instead be applied to repay the Euro Loans made by such Lender resulting
from such conversion.

     (f) For purposes of Section 2.14(e), a notice to any Borrower by any Lender
shall be effective as to each Alternate Currency Loan made to such Borrower by
such Lender, if lawful, on the last day of the Interest Period currently
applicable to such Alternate Currency Loan; in all other cases such notice shall
be effective on the date of receipt thereof by the relevant Borrower.

     2.15 Taxes. (a) All payments made by any Borrower under this Agreement
shall be made free and clear of, and without deduction or withholding for or on
account of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority, excluding
net income taxes and franchise taxes (imposed in lieu of net income taxes)
imposed on the Administrative Agent or any Lender as a result of a present or
former connection between the Administrative Agent or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision or taxing authority thereof or therein (other than any such
connection arising solely from the Administrative Agent or such Lender having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or any other Loan Document). If any such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions or withholdings
("Non-Excluded Taxes") or Other Taxes are required to be withheld from any
amounts payable to the Administrative Agent or any Lender hereunder, the amounts
so payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes and Other Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement, provided, however, that no Borrower shall be required to increase any
such amounts payable to any Lender with respect to any Non-Excluded Taxes (i)
that are attributable to such Lender's failure to comply with the requirements
of paragraph (d) of this Section or (ii) that are taxes imposed on amounts
payable to such Lender at the time such Lender becomes a party to this
Agreement, except to the extent that such Lender's assignor (if any) was
entitled, at the time of assignment, to receive additional amounts from the
relevant Borrower with respect to such Non-Excluded Taxes pursuant to this
paragraph.

     (b) In addition, the Borrowers shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.
<PAGE>
                                                                              26

     (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by any
Borrower, as promptly as possible thereafter the relevant Borrower shall send to
the Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by such Borrower showing payment thereof. If the relevant Borrower
fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent the required
receipts or other required documentary evidence, such Borrower shall indemnify
the Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

     (d) Each Lender that is entitled to an exemption from or reduction of
non-U.S. withholding tax under the law of the jurisdiction in which the Lender
is located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall, at the reasonable request of the Borrowers,
deliver to the Borrowers (with a copy to the Administrative Agent), at such time
or times prescribed by applicable law and such properly completed and executed
documentation prescribed by applicable law as will permit such payments to be
made without withholding or at a reduced rate.

     (e) The agreements in this Section shall survive the termination of this
Agreement and the payment of the Loans and all other amounts payable hereunder.

     2.16 Indemnity. Each Borrower agrees to indemnify each Lender for, and to
hold each Lender harmless from, any loss or expense that such Lender may sustain
or incur as a consequence of (a) default by such Borrower in making a borrowing
of or continuation of Loans after such Borrower has given a notice requesting
the same in accordance with the provisions of this Agreement, (b) default by
such Borrower in making any prepayment of Loans after such Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (c) the
making of a prepayment of Loans on a day that is not the last day of an Interest
Period with respect thereto. Such indemnification may include an amount equal to
the excess, if any, of (i) the amount of interest that would have accrued on the
amount so prepaid, or not so borrowed or continued, for the period from the date
of such prepayment or of such failure to borrow or continue to the last day of
such Interest Period (or, in the case of a failure to borrow or continue, the
Interest Period that would have commenced on the date of such failure) in each
case at the applicable rate of interest for such Loans provided for herein
(excluding, however, the Margin included therein, if any) over (ii) the amount
of interest (as reasonably determined by such Lender) that would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank LIBOR market. A certificate as to any
amounts payable pursuant to this Section submitted to the relevant Borrower by
any Lender shall be conclusive in the absence of manifest error. This covenant
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

     2.17 Change of Lending Office. Each Lender agrees that, upon the occurrence
of any event giving rise to the operation of Section 2.14 or 2.15(a) with
respect to such Lender, it will, if requested by the relevant Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such

<PAGE>
                                                                              27

designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal, regulatory
or other disadvantage, and provided, further, that nothing in this Section shall
affect or postpone any of the obligations of any Borrower or the rights of any
Lender pursuant to Section 2.14 or 2.15(a).

     2.18 Replacement of Lenders. The Borrowers shall be permitted to replace
any Lender that (a) requests reimbursement for amounts owing pursuant to Section
2.14 or 2.15(a) or (b) defaults in its obligation to make Loans hereunder, with
a replacement financial institution; provided that (i) such replacement does not
conflict with any Requirement of Law, (ii) no Event of Default shall have
occurred and be continuing at the time of such replacement, (iii) prior to any
such replacement, such Lender shall have taken no action under Section 2.17 so
as to eliminate the continued need for payment of any amounts owing pursuant to
Section 2.14 or 2.15(a), (iv) the replacement financial institution shall
purchase, at par (unless the Lender being replaced otherwise agrees to accept a
lesser payment in its discretion), all Loans and other amounts owing to such
replaced Lender on or prior to the date of replacement, (v) the relevant
Borrower shall be liable to such replaced Lender under Section 2.16 if any Loan
owing by such Borrower to such replaced Lender shall be purchased other than on
the last day of the Interest Period relating thereto, (vi) the replacement
financial institution, if not already a Lender, shall (A) be reasonably
satisfactory to the Administrative Agent and (B) deliver to the Administrative
Agent an administrative questionnaire, (vii) (A) in the event of a replacement
of a Lender pursuant to clause (a) above, the Borrowers shall deliver to the
Administrative Agent a processing and recordation fee of $3,500 in accordance
with Section 10.6 or (B) in the event of a replacement of a Lender pursuant to
clause (b) above, the replaced Lender shall deliver to the Administrative Agent
a processing and recordation fee of $3,500 in accordance with Section 10.6,
(viii) until such time as such replacement shall be consummated, each Borrower
shall pay all additional amounts (if any) required to be paid by such Borrower
pursuant to Section 2.14 or 2.15(a), as the case may be, and (ix) any such
replacement shall not be deemed to be a waiver of any rights that any Borrower,
the Administrative Agent or any other Lender shall have against the replaced
Lender. In the event of a replacement of a Lender pursuant to this Section 2.18,
such replaced Lender and the replacement financial institution shall promptly
execute and deliver to the Administrative Agent and the Borrowers an Assignment
and Assumption, and shall comply with the provisions of Section 10.6(b)(iii),
(iv) and (v) (other than the requirements included in such clause (v) with
respect to the delivery of consents and the processing and recordation fee,
which are covered above in this Section).

     2.19 Judgment Currency. (a) If, for the purpose of obtaining judgment in
any court, it is necessary to convert a sum owing hereunder in one currency into
another currency, each party hereto agrees, to the fullest extent that it may
effectively do so, that the rate of exchange used shall be that at which, in
accordance with normal banking procedures in the relevant jurisdiction, the
first currency could be purchased with such other currency on the Business Day
immediately preceding the day on which final judgment is given.

     (b) The obligations of each Borrower in respect of any sum due to any party
hereto or any holder of the obligations owing hereunder (the "Applicable
Creditor") shall, notwithstanding any judgment in a currency (the "Judgment
Currency") other than the currency in which such sum is stated to be due
hereunder (the "Agreement Currency"), be discharged only to the extent that, on
the Business Day following receipt by the Applicable Creditor of any sum

<PAGE>
                                                                              28

adjudged to be so due in the Judgment Currency, the Applicable Creditor may in
accordance with normal banking procedures in the relevant jurisdiction purchase
the Agreement Currency with the Judgment Currency; if the amount of the
Agreement Currency so purchased is less than the sum originally due to the
Applicable Creditor in the Agreement Currency, the relevant Borrower as a
separate obligation and notwithstanding any such judgment, agrees to indemnify
the Applicable Creditor against such loss. The obligations of each Borrower
contained in this Section shall survive the termination of this Agreement and
the payment of all other amounts owing hereunder.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

     To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Loans, Thermo Electron hereby represents and warrants
to the Administrative Agent and each Lender, as of the date of this Agreement
(except as to the representations and warranties made as of a date certain,
which shall be true and correct as of such date) and as of the date such
representations and warranties are deemed to be made under Section 4.2(a), that:

     3.1 Financial Condition. The audited consolidated balance sheets of Thermo
Electron and its consolidated Subsidiaries as at December 28, 2002, December 31,
2003 and December 31, 2004 and the related consolidated statements of income and
of cash flows for the fiscal years ended on such dates, reported on by and
accompanied by an unqualified report from Pricewaterhouse Coopers LLP, present
fairly the consolidated financial condition of Thermo Electron and its
consolidated Subsidiaries as at such dates, and the consolidated results of its
operations and its consolidated cash flows for the respective fiscal years then
ended. The unaudited consolidated balance sheet of Thermo Electron and its
consolidated Subsidiaries as at April 2, 2005, and the related unaudited
consolidated statements of income and cash flows for the three-month period
ended on such date, present fairly the consolidated financial condition of
Thermo Electron and its consolidated Subsidiaries as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
three-month period then ended (subject to normal year-end audit adjustments).
All such financial statements, including the related schedules and notes
thereto, have been prepared in accordance with GAAP (subject to the absence of
footnotes with respect to unaudited quarterly statements) applied consistently
throughout the periods involved (except as approved by the aforementioned firm
of accountants and disclosed therein). As of the date of this Agreement, no
Group Member has any material Guarantee Obligations, contingent liabilities and
liabilities for taxes, or any long-term leases or unusual forward or long-term
commitments, including any interest rate or foreign currency swap or exchange
transaction or other obligation in respect of derivatives, other than those that
(i) are not material to Thermo Electron and its Subsidiaries taken as a whole or
(ii) are reflected in the most recent financial statements referred to in this
paragraph or in Thermo Electron's most recent report on Form 10-K or any
subsequent reports on Form 10-Q or Form 8-K filed with the SEC prior to the date
of this Agreement (such filings made prior to the date of this Agreement, the
"SEC Filings"). During the period from December 31, 2004 to and including the
date of this Agreement there has been no Disposition by any Group Member of any
part of its business or property material to Thermo Electron and its
Subsidiaries taken as a whole except as set forth in the most recent financial
statements referred to in this paragraph or in Thermo Electron's SEC Filings.
<PAGE>
                                                                              29

     3.2 No Change. Since December 31, 2004, there has been no development or
event that has had or would reasonably be expected to have a Material Adverse
Effect, except that no representation and warranty is made in this Section 3.2
with respect to the Current Litigation.

     3.3 Existence; Compliance with Law. Each Group Member (a) is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b) has the power and authority, and the legal
right, to own and operate its property, to lease the property it operates as
lessee and to conduct the business in which it is currently engaged, (c) is duly
qualified as a foreign corporation and in good standing under the laws of each
jurisdiction where its ownership, lease or operation of property or the conduct
of its business requires such qualification and (d) is in compliance with all
Requirements of Law except to the extent that the failure to conform to the
requirements of clauses (a) through (d) could not, in the aggregate, reasonably
be expected to have a Material Adverse Effect.

     3.4 Power; Authorization; Enforceable Obligations. Thermo Electron and each
Borrower has the power and authority, and the legal right, to make, deliver and
perform the Loan Documents to which it is a party and, in the case of each
Borrower, to borrow hereunder. Thermo Electron and each Borrower have taken all
necessary organizational action to authorize the execution, delivery and
performance of the Loan Documents to which it is a party and, in the case of
each Borrower, to authorize the extensions of credit on the terms and conditions
of this Agreement. No consent or authorization of, filing with (other than any
SEC filing by Thermo Electron in compliance with the SEC disclosure
obligations), notice to or other act by or in respect of, any Governmental
Authority or any other Person is required of any Group Member in connection with
the borrowings by any Borrower hereunder or with the execution, delivery and
performance by Thermo Electron or any Borrower, or the validity or
enforceability against Thermo Electron or any Borrower, of this Agreement or any
of the Loan Documents. This Agreement has been duly executed and delivered on
behalf of Thermo Electron and each Borrower. This Agreement constitutes, and
each other Loan Document upon execution will constitute, a legal, valid and
binding obligation of Thermo Electron and each Borrower, as applicable,
enforceable against Thermo Electron or such Borrower in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

     3.5 No Legal Bar. Except as, in the aggregate, could not reasonably be
expected to have a Material Adverse Effect, the execution, delivery and
performance of this Agreement and the other Loan Documents, the borrowings
hereunder and the use of the proceeds thereof will not violate any Requirement
of Law or any Contractual Obligation of any Group Member and will not result in,
or require, the creation or imposition of any Lien on any of their respective
properties or revenues pursuant to any Requirement of Law or any such
Contractual Obligation.

     3.6 Litigation. It is not probable that the Current Litigation will have a
Material Adverse Effect, and no other litigation, investigation or proceeding of
or before any arbitrator or Governmental Authority is pending or, to the
knowledge of Thermo Electron,

<PAGE>
                                                                              30

threatened by or against any Group Member or against any of their respective
properties or revenues that would reasonably be expected to have a Material
Adverse Effect.

     3.7 Ownership of Property; Liens. Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect, each Group Member has
title in fee simple to, or a valid leasehold interest in, all its real property,
and good title to, or a valid leasehold interest in, all its other property, and
none of such property is subject to any Lien except as permitted by Section 6.4.

     3.8 Taxes. Except as, in the aggregate, could not reasonably be expected to
have a Material Adverse Effect, each Group Member has filed or caused to be
filed all material tax returns that are required to be filed by each of them in
each applicable jurisdiction and has paid all taxes shown to be due and payable
on said returns or on any assessments made against it or any of its property and
all other taxes, fees or other charges imposed on it or any of its property by
any Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the relevant Group Member).

     3.9 Federal Regulations. No part of the proceeds of any Loans will be used
for any purpose that violates the provisions of Regulation U or any of the other
Regulations of the Board. If requested by any Lender or the Administrative
Agent, each Borrower will furnish to the Administrative Agent and each Lender a
statement to the foregoing effect in conformity with the requirements of FR Form
G-3 or FR Form U-1, as applicable, referred to in Regulation U.

     3.10 ERISA. Except as, in the aggregate, could not reasonably be expected
to have a Material Adverse Effect, neither a Reportable Event nor an
"accumulated funding deficiency" (within the meaning of Section 412 of the Code
or Section 302 of ERISA) has occurred during the five-year period prior to the
date on which this representation is made or deemed made with respect to any
Plan, and each Plan has complied in all material respects with the applicable
provisions of ERISA and the Code. No termination of a Single Employer Plan has
occurred that could reasonably be expected to have a Material Adverse Effect,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period. The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by an amount that is material in relation to Consolidated
Net Worth. Except as in the aggregate could not reasonably be expected to have a
Material Adverse Effect, neither Thermo Electron nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan, and
neither Thermo Electron nor any Commonly Controlled Entity would become subject
to any liability under ERISA that, in the aggregate, could reasonably be
expected to result in a Material Adverse Effect if Thermo Electron or any such
Commonly Controlled Entity were to withdraw completely from all Multiemployer
Plans as of the valuation date most closely preceding the date on which this
representation is made or deemed made. No such Multiemployer Plan is in
Reorganization or Insolvent under circumstances that could reasonably be
expected to result in a Material Adverse Effect.
<PAGE>
                                                                              31

     3.11 Investment Company Act; Other Regulations. Neither Thermo Electron nor
any Borrower is an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. Neither Thermo Electron nor any Borrower is subject to regulation
under any Requirement of Law (other than Regulation X of the Board) that limits
its ability to incur Indebtedness.

     3.12 Use of Proceeds. The proceeds of the Loans shall be used by the
Borrowers and their respective Subsidiaries for working capital, acquisitions,
repurchases of Capital Stock, debentures and other securities of the Borrowers,
the refinancing of present and future debt and general corporate purposes.

     3.13  Environmental  Matters.  Except  as,  in  the  aggregate,  could  not
reasonably be expected to have a Material Adverse Effect:

     (a) the facilities and properties owned, leased or operated by any Group
Member (the "Properties") do not contain, and have not previously contained, any
Materials of Environmental Concern in amounts or concentrations or under
circumstances that constitute or constituted a violation of, or could give rise
to liability under, any Environmental Law;

     (b) no Group Member has received or is aware of any notice of violation,
alleged violation, non-compliance, liability or potential liability regarding
environmental matters or compliance with Environmental Laws with regard to any
of the Properties or the business operated by any Group Member (the "Business"),
nor does Thermo Electron have knowledge or reason to believe that any such
notice will be received or is being threatened;

     (c) Materials of Environmental Concern have not been transported or
disposed of from the Properties in violation of, or in a manner or to a location
that could give rise to liability under, any Environmental Law, nor have any
Materials of Environmental Concern been generated, treated, stored or disposed
of at, on or under any of the Properties in violation of, or in a manner that
could give rise to liability under, any applicable Environmental Law;

     (d) no judicial proceeding or governmental or administrative action is
pending or, to the knowledge of Thermo Electron, threatened, under any
Environmental Law to which any Group Member is or will be named as a party with
respect to the Properties or the Business, nor are there any consent decrees or
other decrees, consent orders, administrative orders or other orders, or other
administrative or judicial requirements outstanding under any Environmental Law
with respect to the Properties or the Business;

     (e) there has been no release or threat of release of Materials of
Environmental Concern at or from the Properties, or arising from or related to
the operations of any Group Member in connection with the Properties or
otherwise in connection with the Business, in violation of or in amounts or in a
manner that could give rise to liability under Environmental Laws;

     (f) the Properties and all operations at the Properties are in compliance,
and have in the last five years been in compliance, with all applicable
Environmental Laws, and there is no contamination at, under or about the
Properties or violation of any Environmental Law with respect to the Properties
or the Business; and <PAGE>
                                                                              32

     (g) no Group Member has assumed any liability of any other Person under
Environmental Laws.

     3.14 Accuracy of Information, etc. No statement or information contained in
this Agreement, the Confidential Information Package or any other document,
certificate or statement furnished by or on behalf of Thermo Electron or any
Borrower to the Administrative Agent or the Lenders, or any of them, for use in
connection with the transactions contemplated by this Agreement or the other
Loan Documents, contained as of the date such statement, information, document
or certificate was so furnished (or, in the case of the Confidential Information
Package, as of the date of this Agreement) when taken together with the SEC

or

then, and in any such event, (A) if such event is an Event of Default specified

any Borrower, automatically the Commitments shall immediately terminate and the

Agreement and the other Loan Documents shall immediately become due and payable,
and (B) if such event is any other Event of Default, either or both of the

expressly waived by Thermo Electron and the Borrowers.

                             SECTION 8. THE AGENTS

     8.1 Appointment. Each Lender hereby irrevocably designates and appoints the
Administrative Agent as the agent of such Lender under this Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes the
Administrative Agent, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Loan Documents and to exercise
such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

     8.2 Delegation of Duties. The Administrative Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or

<PAGE>
                                                                              46

attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Administrative Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys in-fact
selected by it with reasonable care.

     8.3 Exculpatory Provisions. Neither any Agent nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable to any Lender for any action lawfully taken or omitted to be taken by
it or such Person under or in connection with this Agreement or any other Loan
Document (except to the extent that any of the foregoing are found by a final
and nonappealable decision of a court of competent jurisdiction to have resulted
from its or such Person's own gross negligence or willful misconduct) or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any Loan Party or any officer thereof
contained in this Agreement or any other Loan Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agents under or in connection with, this Agreement or any other Loan
Document or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document or for any failure
of any Loan Party a party thereto to perform its obligations hereunder or
thereunder. The Agents shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

     8.4 Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any instrument,
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including counsel to Thermo Electron and the Borrowers), independent
accountants and other experts selected by the Administrative Agent. The
Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders (or, if so specified
by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all Lenders), and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

     8.5 Notice of Default. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default unless
the Administrative Agent has received notice from a Lender, Thermo Electron or a
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Lenders. The Administrative Agent

<PAGE>
                                                                              47

shall take such action with respect to such Default or Event of Default as shall
be reasonably directed by the Required Lenders (or, if so specified by this
Agreement, all Lenders); provided that unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Lenders.

     8.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly
acknowledges that neither the Agents nor any of their respective officers,
directors, employees, agents, attorneys-in-fact or affiliates have made any
representations or warranties to it and that no act by any Agent hereafter
taken, including any review of the affairs of a Loan Party or any affiliate of a
Loan Party, shall be deemed to constitute any representation or warranty by any
Agent to any Lender. Each Lender represents to the Agents that it has,
independently and without reliance upon any Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and their
affiliates and made its own decision to make its Loans hereunder and enter into
this Agreement. Each Lender also represents that it will, independently and
without reliance upon any Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of any Loan Party or any affiliate of
a Loan Party that may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

     8.7 Indemnification. The Lenders agree to indemnify each Agent in its
capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to their
respective Loan Percentages in effect on the date on which indemnification is
sought under this Section (or, if indemnification is sought after the date upon
which the Commitments shall have terminated and the Loans shall have been paid
in full, ratably in accordance with such Loan Percentages immediately prior to
such date), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (whether before or after the payment
of the Loans) be imposed on, incurred by or asserted against such Agent in any
way relating to or arising out of, the Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by such Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements that are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from such <PAGE>
                                                                              48

Agent's gross negligence or willful misconduct. The agreements in this Section
shall survive the payment of the Loans and all other amounts payable hereunder.

     8.8 Agent in Its Individual Capacity. Each Agent and its affiliates may
make loans to, accept deposits from and generally engage in any kind of business
with any Loan Party as though such Agent were not an Agent. With respect to
Loans made or renewed by it, each Agent shall have the same rights and powers
under this Agreement and the other Loan Documents as any Lender and may exercise
the same as though it were not an Agent, and the terms "Lender" and "Lenders"
shall include each Agent in its individual capacity.

     8.9 Successor Administrative Agent. The Administrative Agent may resign as
Administrative Agent upon 10 days' notice to the Lenders and Thermo Electron. If
the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor agent
shall (unless an Event of Default under Section 7(a) or Section 7(f) with
respect to Thermo Electron or any Borrower shall have occurred and be
continuing) be subject to approval by Thermo Electron (which approval shall not
be unreasonably withheld or delayed), whereupon such successor agent shall
succeed to the rights, powers and duties of the Administrative Agent, and the
term "Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become
effective, and the Lenders shall assume and perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above. After any retiring
Administrative Agent's resignation as Administrative Agent, the provisions of
this Section 8 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Administrative Agent under this Agreement and the
other Loan Documents.

     8.10 Syndication Agent and Co-Documentation Agents. Neither the Syndication
Agent nor any Co-Documentation Agent shall have any duties or responsibilities
hereunder in its capacity as such.

                      SECTION 9. THERMO ELECTRON GUARANTEE

     9.1 Guarantee (a) To induce the Lenders to execute and deliver this
Agreement and to make the Loans, and in consideration thereof, Thermo Electron
hereby unconditionally and irrevocably guarantees to the Administrative Agent,
for the ratable benefit of the Lenders and their respective successors,
indorsees and assigns, the prompt and complete payment and performance when due
(whether at the stated maturity, by acceleration or otherwise) of the
Obligations, and Thermo Electron further agrees to pay the expenses which may be
paid or incurred by the Administrative Agent or the Lenders in collecting any or
all of the Obligations and/or enforcing any rights under this Section 9.1.
<PAGE>
                                                                              49

     (b) Anything herein to the contrary notwithstanding, the maximum liability
of Thermo Electron hereunder shall in no event exceed the amount which can be
guaranteed by Thermo Electron under applicable federal and state laws relating
to the insolvency of debtors.

     (c) The guarantee contained in this Section 9 shall remain in full force
and effect and be binding in accordance with and to the extent of its terms upon
Thermo Electron and the successors and assigns thereof, and shall inure to the
benefit of the Lenders and their successors and permitted assigns, until all the
Obligations and the obligations of Thermo Electron under the guarantee contained
in this Section 9 shall have been satisfied by payment in full and the
Commitments shall be terminated, notwithstanding that from time to time during
the term of this Agreement the Borrowers may be free from any Obligations.

     9.2 No Subrogation. Notwithstanding any payment made by Thermo Electron
hereunder or any set-off or application of funds of Thermo Electron by the
Administrative Agent or any Lender, Thermo Electron shall not be entitled to be
subrogated to any of the rights of the Administrative Agent or any Lender
against any Borrower or any collateral security or guarantee or right of offset
held by the Administrative Agent or any Lender for the payment of the
Obligations, nor shall Thermo Electron seek or be entitled to seek any
contribution or reimbursement from any Borrower in respect of payments made by
Thermo Electron hereunder, until all amounts owing to the Administrative Agent
and the Lenders by any Borrower on account of the Obligations are paid in full
and the Commitments are terminated. If any amount shall be paid to Thermo
Electron on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by
Thermo Electron in trust for the Administrative Agent and the Lenders and shall,
forthwith upon receipt by Thermo Electron, be turned over to the Administrative
Agent in the exact form received by Thermo Electron (duly indorsed by Thermo
Electron to the Administrative Agent, if required), to be applied against the
Obligations, whether matured or unmatured, in such order as the Administrative
Agent may determine.

     9.3 Amendments, etc. with respect to the Obligations. Thermo Electron shall
remain obligated hereunder notwithstanding that, without any reservation of
rights against Thermo Electron and without notice to or further assent by Thermo
Electron, any demand for payment of any of the Obligations made by the
Administrative Agent or any Lender may be rescinded by the Administrative Agent
or such Lender and any of the Obligations continued, and the Obligations, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Administrative
Agent or any Lender, and this Agreement and the Notes and any other documents
executed and delivered in connection therewith may be amended, modified,
supplemented or terminated, in whole or in part, as the Administrative Agent (or
the Required Lenders or all Lenders, as the case may be) may deem advisable from
time to time, and any collateral security, guarantee or right of offset at any
time held by the Administrative Agent or any Lender for the payment of the
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Obligations or for the guarantee contained in this Section 9 or any property
subject thereto.
<PAGE>
                                                                              50

     9.4 Guarantee Absolute and Unconditional. Thermo Electron waives any and
all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon the guarantee contained in this Section 9 or acceptance of the
guarantee contained in this Section 9; the Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended, amended or waived, in reliance upon the guarantee contained in this
Section 9; and all dealings between the Borrowers and Thermo Electron, on the
one hand, and the Administrative Agent and the Lenders, on the other hand,
likewise shall be conclusively presumed to have been had or consummated in
reliance upon the guarantee contained in this Section 9. To the fullest extent
permitted by applicable law, Thermo Electron waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon any
Borrower or Thermo Electron with respect to the Obligations. Thermo Electron
understands and agrees that the guarantee contained in this Section 9 shall be
construed as a continuing, absolute and unconditional guarantee of payment
without regard to (a) the validity or enforceability of this Agreement or any
Note, any of the Obligations or any other collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by the Administrative Agent or any Lender, (b) any defense, set-off or
counterclaim (other than a defense of payment or performance) which may at any
time be available to or be asserted by any Borrower or any other Person against
the Administrative Agent or any Lender, or (c) any other circumstance whatsoever
(with or without notice to or knowledge of the Borrowers or Thermo Electron)
which constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrowers for the Obligations, or of Thermo Electron under the
guarantee contained in this Section 9, in bankruptcy or in any other instance.
When making any demand hereunder or otherwise pursuing its rights and remedies
hereunder against Thermo Electron the Administrative Agent or any Lender may,
but shall be under no obligation to, make a similar demand on or otherwise
pursue such rights and remedies as it may have against any Borrower, or any
other Person or against any collateral security or guarantee for the Obligations
or any right of offset with respect thereto, and any failure by the
Administrative Agent or any Lender to make any such demand, to pursue such other
rights or remedies or to collect any payments from the Borrowers, or any other
Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of any Borrower, or any other
Person or any such collateral security, guarantee or right of offset, shall not
relieve Thermo Electron of any obligation or liability hereunder, and shall not
impair or affect the rights and remedies, whether express, implied or available
as a matter of law, of the Administrative Agent or any Lender against Thermo
Electron. For the purposes hereof "demand" shall include the commencement and
continuance of any legal proceedings.

     9.5 Reinstatement. The guarantee contained in this Section 9 shall continue
to be effective, or be reinstated, as the case may be, if at any time payment,
or any part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of any
Borrower or Thermo Electron, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, any
Borrower or Thermo Electron or any substantial part of its property, or
otherwise, all as though such payments had not been made.

     9.6 Payments. Thermo Electron hereby guarantees that payments hereunder
will be paid to the Administrative Agent without set-off or counterclaim in the
applicable currency at the Funding Office.

     9.7 Independent Obligations. The obligations of Thermo Electron under the
guarantee contained in this Section 9 are independent of the obligations of the
Borrowers, and a separate action or actions may be brought and prosecuted
against Thermo Electron whether or not any Borrower is joined in any such action
or actions. Thermo Electron waives, to the fullest extent permitted by law, the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement thereof.

                           SECTION 10. MISCELLANEOUS

     10.1 Amendments and Waivers. Neither this Agreement, any other Loan
Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1. The

consent of the Required Lenders, the Administrative Agent, the Borrowers and
Thermo Electron may, from time to time, (a) enter into written amendments,
supplements or modifications hereto and to the other Loan Documents for the
purpose of adding any provisions to this Agreement or the other Loan Documents
or changing in any manner the rights of the Lenders, Thermo Electron or the
Borrowers hereunder or thereunder or (b) waive, on such terms and conditions as
the Required Lenders or the Administrative Agent, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or the
other Loan Documents or any Default or Event of Default and its consequences;
provided, however, that no such waiver and no such amendment, supplement or
modification shall (i) forgive the principal amount or extend the final
scheduled date of maturity of any Loan, reduce the stated rate of any interest
or fee payable hereunder (except in connection with the waiver of applicability
of any post-default increase in interest rates (which waiver shall be effective
with the consent of the Required Lenders)) or extend the scheduled date of any
payment thereof, or increase the amount or extend the expiration date of any
Lender's Commitment, in each case without the written consent of each Lender
directly affected thereby; (ii) eliminate or reduce the voting rights of any
Lender under this Section 10.1 without the written consent of such Lender; (iii)
reduce any percentage specified in the definition of Required Lenders or consent
to the assignment or transfer by Thermo Electron or any Borrower of any of its

provision of Section 8 without the written consent of the Administrative Agent;

Currency Loans may be made under this Agreement without the written consent of
all the Lenders. Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon Thermo Electron, the Borrowers, the Lenders, the Administrative Agent and
all future holders of the Loans. In the case of any waiver, Thermo Electron, the
Borrowers, the Lenders and the Administrative Agent shall be restored to their
former position and rights hereunder and under the other Loan Documents, and any
Default or Event of Default waived shall be deemed to be

other Default or Event of Default, or impair any right consequent thereon.

     10.2 Notices. All notices, requests and demands to or upon the respective

     Notices and other communications to the Lenders hereunder may be delivered
or furnished by electronic communications pursuant to procedures approved by the
Administrative Agent; provided that the foregoing shall not apply to notices
pursuant to Section 2 unless otherwise agreed by the Administrative Agent and
the applicable Lender. The Administrative Agent, Thermo Electron or any Borrower
may, in its discretion, agree to accept notices and other communications to it
hereunder by electronic communications pursuant to procedures approved by it;
provided that approval of such procedures may be limited to particular notices
or communications and, provided, further, that no such agreement referred to in
this sentence shall be effective unless it is set forth in a written document
executed by the Administrative Agent and Thermo Electron.

     10.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising, on the part of the Administrative Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any

     10.4 Survival of Representations and Warranties. All representations and
warranties made hereunder, in the other Loan Documents and in any document,
certificate or statement delivered pursuant hereto or in connection herewith
shall survive the execution and delivery of this Agreement and the making of the
Loans hereunder.

     10.5 Payment of Expenses. The Borrowers jointly and severally agree (a) to
pay or reimburse the Administrative Agent for all its reasonable out-of-pocket
costs and expenses incurred in connection with the development, preparation and
execution of, and any amendment, supplement or modification to, this Agreement
and the other Loan Documents and any other documents prepared in connection
herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including the reasonable fees and
disbursements of counsel to the Administrative Agent, with statements with
respect to the foregoing to be submitted to the Borrowers prior to the Closing
Date (in the case of amounts to be paid on the Closing Date) and from time to
time thereafter on a quarterly basis or such other periodic basis as the
Administrative Agent shall deem appropriate, (b) after the occurrence and during
the continuance of an Event of Default, to pay or reimburse each Lender and the
Administrative Agent for all its reasonable out-of-pocket costs and expenses
incurred in connection with the enforcement or preservation of any rights under
this Agreement, the other Loan Documents and any such other documents, including
the fees and disbursements of counsel to each Lender and of counsel to the
Administrative Agent and (c) to pay, indemnify, and hold each Lender and the
Administrative Agent and their respective officers, directors, employees,
affiliates, agents and controlling persons (each, an "Indemnitee") harmless from
and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever (including reasonable fees and expenses of counsel)
with respect to such Lender or Administrative Agent being a party to this
Agreement or any other Loan Document, or the enforcement or performance of this
Agreement, the other Loan Documents and any such other documents, including any
of the foregoing relating to the use of proceeds of the Loans or the violation
of, noncompliance with or liability under, any Environmental Law applicable to
the operations of any Group Member or any of the Properties (all the foregoing
in this clause (c), collectively, the "Indemnified Liabilities"), provided, that
no Borrower shall have any obligation hereunder to any Indemnitee with respect
to Indemnified Liabilities to the extent such Indemnified Liabilities are found
by a final and nonappealable decision of a court of competent jurisdiction to
have resulted from the gross negligence or willful misconduct of such Indemnitee
or the breach by such Indemnitee of its obligations under this Agreement.
Without limiting the foregoing, and to the extent permitted by applicable law,
each Borrower agrees not to assert and to cause its Subsidiaries not to assert,
and hereby waives and agrees to cause its Subsidiaries to waive, all rights for
contribution or any other rights of recovery with respect to all claims,
demands, penalties, fines, liabilities, settlements, damages, costs and expenses
of whatever kind or nature, under or related to Environmental Laws, that any of
them might have by statute or otherwise against any Indemnitee. All amounts due
under this Section 10.5 shall be payable not later than 10 days after written
demand therefor. Statements payable by the Borrowers pursuant to this Section
10.5 shall be submitted to Office of the General Counsel (Telephone No. (781)
622-1000) (Telecopy No. (781) 622-1283), at the address of the Borrowers set
forth in Section 10.2, or to such other Person or address as may be hereafter
designated by the Borrowers in a written notice to the Administrative Agent. The
agreements in this Section 10.5 shall survive repayment of the Loans and all
other amounts payable hereunder.

     10.6 Successors and Assigns; Participations and Assignments. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns permitted hereby,
except that (i) neither Thermo Electron nor any Borrower may assign or otherwise
transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by Thermo
Electron or any Borrower without such consent shall be null and void) and (ii)
no Lender may assign or otherwise transfer its rights or obligations hereunder
except in accordance with this Section.

     (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any
Lender may assign to one or more assignees (each, an "Assignee") all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitments and the Loans at the time owing to it) with the prior
written consent (such consent not to be unreasonably withheld (it being agreed
that it will not be unreasonable for Thermo Electron to withhold its consent on
the basis that it is unable to determine whether or not the proposed Assignee is
a Professional Market Party if it shall not have been provided with information
regarding the proposed Assignee that is adequate to form the basis for such
determination)) of:

               (A) Thermo Electron, provided that no consent of Thermo Electron
          shall be required for an assignment to an existing Lender, or, if an
          Event of Default has occurred and is continuing, any other Person; and

               (B) the Administrative Agent, provided that no consent of the
          Administrative Agent shall be required for an assignment of any
          Commitment to an assignee that is a Lender with a Commitment
          immediately prior to giving effect to such assignment.

          (ii) Assignments shall be subject to the following additional
     conditions:

               (A) except in the case of an assignment to an existing Lender, an
          affiliate of a Lender or an Approved Fund or an assignment of the
          entire remaining amount of the assigning Lender's Commitments or
          Loans, the amount of the Commitments or Loans of the assigning Lender
          subject to each such assignment (determined as of the date the
          Assignment and Assumption with respect to such assignment is delivered
          to the Administrative Agent) shall not be less than (euro)5,000,000
          unless each of Thermo Electron and the Administrative Agent otherwise
          consent, provided that (1) no such consent of Thermo Electron shall be
          required if an Event of Default has occurred and is continuing and (2)
          such amounts shall be aggregated in respect of each Lender and its
          affiliates or Approved Funds, if any;

               (B) the parties to each assignment shall execute and deliver to
          Thermo Electron, the Borrowers and the Administrative Agent an
          Assignment and Assumption, and at such time deliver to the
          Administrative Agent a processing and recordation fee of $3,500;
<PAGE>
                                                                              56

               (C) the Assignee, if it shall not be a Lender, shall deliver to
          the Administrative Agent an administrative questionnaire; and

               (D) to the extent applicable, the provisions of Section 10.6(g).

     For the purposes of this Section 10.6, the term "Approved Fund" has the
following meaning:

                    "Approved Fund" means any Person (other than a natural
               person) that is engaged in making, purchasing, holding or
               investing in bank loans and similar extensions of credit in the
               ordinary course of its business and that is administered or
               managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an
               entity or an Affiliate of an entity that administers or manages a
               Lender.

          (iii) Subject to acceptance and recording thereof pursuant to
     paragraph (b)(iv) below, from and after the effective date specified in
     each Assignment and Assumption the Assignee thereunder shall be a party
     hereto and, to the extent of the interest assigned by such Assignment and
     Assumption, have the rights and obligations of a Lender under this
     Agreement, and the assigning Lender thereunder shall, to the extent of the
     interest assigned by such Assignment and Assumption, be released from its
     obligations under this Agreement (and, in the case of an Assignment and
     Assumption covering all of the assigning Lender's rights and obligations
     under this Agreement, such Lender shall cease to be a party hereto but
     shall continue to be entitled to the benefits of Sections 2.14, 2.15, 2.16
     and 10.5). Any assignment or transfer by a Lender of rights or obligations
     under this Agreement that does not comply with this Section 10.6 shall be
     treated for purposes of this Agreement as a sale by such Lender of a
     participation in such rights and obligations in accordance with paragraph
     (c) of this Section.

          (iv) The Administrative Agent, acting for this purpose as an agent of
     the Borrowers, shall maintain at one of its offices a copy of each
     Assignment and Assumption delivered to it and a register for the
     recordation of the names and addresses of the Lenders, and the Commitments
     of, and principal amount of the Loans owing to, each Lender pursuant to the
     terms hereof from time to time (the "Register"). The entries in the
     Register shall be conclusive, and Thermo Electron, the Borrowers, the
     Administrative Agent, and the Lenders may treat each Person whose name is
     recorded in the Register pursuant to the terms hereof as a Lender hereunder
     for all purposes of this Agreement, notwithstanding notice to the contrary.

          (v) Upon its receipt of a duly completed Assignment and Assumption
     executed by an assigning Lender and an Assignee, the Assignee's completed
     administrative questionnaire (unless the Assignee shall already be a Lender
     hereunder), the processing and recordation fee referred to in paragraph (b)
     of this Section and any written consent to such assignment required by
     paragraph (b) of this Section, the Administrative Agent shall accept such
     Assignment and Assumption and record the information contained therein in
     the Register. No assignment shall be effective for purposes of this
     Agreement unless it has been recorded in the Register as provided in this
     paragraph.

                                                                              57

     (c) (i) Any Lender may, without the consent of Thermo Electron, the
Borrowers or the Administrative Agent, sell participations to one or more banks
or other entities (a "Participant") in all or a portion of such Lender's rights
and obligations under this Agreement (including all or a portion of its
Commitments and the Loans owing to it); provided that (A) such Lender's
obligations under this Agreement shall remain unchanged, (B) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (C) Thermo Electron, the Borrowers, the Administrative
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement may provide that such Lender
will not, without the consent of the Participant, agree to any amendment,
modification or waiver that (1) requires the consent of each Lender directly
affected thereby pursuant to the proviso to the second sentence of Section 10.1
and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this
Section, Thermo Electron and each Borrower agrees that each Participant shall be
entitled to the benefits of Sections 2.14, 2.15 and 2.16 to the same extent as
if it were a Lender and had acquired its interest by assignment pursuant to
paragraph (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 10.7(b) as though it were a
Lender, provided such Participant shall be subject to Section 10.7(a) as though
it were a Lender.

          (ii) A Participant shall not be entitled to receive any greater
payment under Section 2.14 or 2.15 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with Thermo
Electron's prior written consent. No Participant shall be entitled to the
benefits of Section 2.15 unless such Participant provides such forms,
certificates or other evidence, if any, with respect to withholding tax matters
as required under Section 2.15(d).

     (d) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a security
interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or Assignee for such Lender as a party hereto.

     (e) Each Borrower, upon receipt of written notice from the relevant Lender,
agrees to issue Notes to any Lender requiring Notes to facilitate transactions
of the type described in paragraph (d) above.

     (f) Notwithstanding the foregoing, any Lender may assign its rights and
obligations to a Conduit Lender organized and administered by such Lender,
provided that such assignment shall be subject to all the requirements of the
definition of the term "Conduit Lender" in Section 1.1. Notwithstanding the
foregoing, any Conduit Lender may assign any or all of the Loans it may have
funded hereunder to its designating Lender without the consent of Thermo
Electron or the Administrative Agent and without regard to the limitations set
forth in Section 10.6(b). Each of the Administrative Agent, Thermo Electron,
each Borrower and each Lender hereby confirms that it will not institute against
a Conduit Lender or join any other Person in

<PAGE>
                                                                              58

instituting against a Conduit Lender any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceeding under any state bankruptcy or
similar law, for one year and one day after the payment in full of the latest
maturing commercial paper note issued by such Conduit Lender; provided, however,
that each Lender designating any Conduit Lender hereby agrees to indemnify, save
and hold harmless each other party hereto for any loss, cost, damage or expense
arising out of its inability to institute such a proceeding against such Conduit
Lender during such period of forbearance.

     (g) If, on the date of any proposed assignment, it is a requirement of
Dutch law that each Lender to a Dutch Borrower must be a Professional Market
Party:

          (i) any Lender which proposes to assign all or a portion of its rights
     and obligations under this Agreement to an Assignee shall give Thermo
     Finance B.V. and Thermo Electron at least four Business Days' prior written
     notice thereof, and such assignment shall, subject to satisfaction of all
     the applicable requirements of this Section 10.6, become effective (A) if
     Thermo Electron shall have consented thereto pursuant to Section
     10.6(b)(i)(A) or (B) if, pursuant to the proviso to Section 10.6(b)(i)(A),
     the consent of Thermo Electron to the proposed assignment is not required,
     as of the close of business in London on the fourth Business Day after
     receipt by Thermo Finance B.V. and Thermo Electron of such notice unless,
     on or prior to such time on such fourth Business Day, Thermo Finance B.V.
     shall have demonstrated to the reasonable satisfaction of the
     Administrative Agent that either (x) the proposed Assignee is not a
     Professional Market Party or (y) Thermo Finance B.V., acting in good faith,
     has been unable to determine (including on the basis of information
     delivered to Thermo Finance B.V. and Thermo Electron together with such
     notice) whether the proposed Assignee is a Professional Market Party (it
     being understood that, if Thermo Finance B.V. shall have so demonstrated to
     the Administrative Agent on or prior to such time on such fourth Business
     Day, such assignment shall not become effective);

          (ii) no assignment will be effective unless both the Assignee and
     Thermo Finance B.V. have complied with the requirements of this Section
     10.6(g);

          (iii) on the date the assignment becomes effective the Assignee must
     make the representation on the terms set out in clause 3(b) of the
     Assignment and Assumption;

          (iv) on the date that an Assignee becomes party to this Agreement as a
     Lender, Thermo Finance B.V. must represent pursuant to Section 3.15(c) that
     on that date it has verified the status of such Assignee as a Professional
     Market Party.

     10.7 Adjustments; Set-off. (a) Except to the extent that this Agreement
expressly provides for payments to be allocated to a particular Lender, if any
Lender (a "Benefited Lender") shall receive any payment of all or part of the
Obligations owing to it (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in Section 7(f), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of the Obligations owing to
such other Lender, such Benefited Lender shall purchase for cash from the other
Lenders a participating

<PAGE>
                                                                              59

interest in such portion of the Obligations owing to each such other Lender, or
shall provide such other Lenders with the benefits of any such collateral, as
shall be necessary to cause such Benefited Lender to share the excess payment or
benefits of such collateral ratably with each of the Lenders; provided, however,
that if all or any portion of such excess payment or benefits is thereafter
recovered from such Benefited Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest.

     (b) In addition to any rights and remedies of the Lenders provided by law,
each Lender shall have the right after the occurrence and during the
continuation of an Event of Default, without prior notice to Thermo Electron or
any Borrower, any such notice being expressly waived by Thermo Electron and each
Borrower to the extent permitted by applicable law, upon any amount becoming due
and payable by Thermo Electron or any Borrower hereunder (whether at the stated
maturity, by acceleration or otherwise), to set off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Lender or
any branch or agency thereof to or for the credit or the account of Thermo
Electron or the relevant Borrower, as the case may be. Each Lender agrees
promptly to notify Thermo Electron or the relevant Borrower and the
Administrative Agent after any such setoff and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such setoff and application.

     (c) By joining in this Agreement, the Administrative Agent and each Lender
hereby waive (doet afstand van), with respect to any Dutch bank account
maintained by Thermo Electron or any Borrower, any right of pledge over any
balance standing to credit of such Dutch bank account which the Administrative
Agent or any Lender may have or at any time in the future may acquire under its
general banking conditions or otherwise, under the general terms and conditions
(algemene voorwaarden) of any member of the Dutch Bankers' Association
(Nederlandse Vereniging van Banken) or any similar term applied by a financial
institution in the Netherlands pursuant to its general terms and conditions;
provided, however, that nothing in this paragraph (c) shall be deemed to limit
in any way the rights of any Lender under paragraph (b) above.

     10.8 Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with Thermo Electron and the Administrative Agent.

     10.9 Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

Borrower hereby irrevocably and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding
relating to this Agreement and the other Loan Documents to which it is a party,
or for recognition and enforcement of any judgment in respect thereof, to the
non-exclusive general jurisdiction of the courts of the State of New York, the
courts of the United States for the Southern District of New York, and appellate
courts from any thereof;

     (b) consents that any such action or proceeding may be brought in such
courts and waives any objection that it may now or hereafter have to the venue
of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c) agrees that service of process in any such action or proceeding may be
effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid, to Thermo Electron at its
address set forth in Section 10.2 or, as the case may be, to the relevant
Borrower in care of Thermo Electron at Thermo Electron's address set forth in
Section 10.2 or at such other address of which the Administrative Agent shall
have been notified pursuant thereto; provided that, in the case of Thermo
Luxembourg, a copy thereof shall also be mailed to its registered office at 13,
boulevard du Prince Henri, L-1724 Luxembourg;

     (d) agrees that nothing herein shall affect the right to effect service of
process in any other manner permitted by law or shall limit the right to sue in
any other jurisdiction; and

     (e) waives, to the maximum extent not prohibited by law, any right it may
have to claim or recover in any legal action or proceeding referred to in this
Section any special, exemplary, punitive or consequential damages.

     10.13 Acknowledgements. Thermo Electron and each Borrower hereby

     (b) neither the Administrative Agent nor any Lender has any fiduciary
relationship with or duty to Thermo Electron or any Borrower arising out of or

therewith is solely that of creditor and debtor; and

     (c) no joint venture is created hereby or by the other Loan Documents or

confidential all non-public information provided to it by any Group Member, the
Administrative Agent or any Lender pursuant to or in connection with this

Administrative Agent, any other Lender or any affiliate thereof solely for the
purposes of, or otherwise in connection with, this Agreement, (b) subject to an
express agreement to maintain the confidentiality of such information in

respective affiliates, in violation of this Section 10.14 (provided that neither
the Administrative Agent nor any Lender shall be deemed to have violated this
Section if it, or any of its employees, directors, agents, attorneys,
accountants or other professional advisors or any of their respective affiliates
(each Lender (or, as the case may be, the Administrative Agent), together with
each such other Person employed by it, a "Subject Group"), shall publicly
disclose any confidential information which has previously been publicly
disclosed, without the knowledge of the Person making such subsequent
disclosure, by a Person which is a member of another Subject Group), (h) to the

<PAGE>

similar authority with respect to the Administrative Agent or such Lender, as
the case may be, and that is seeking such disclosure solely in connection with
an investigation, litigation or other proceeding that does not otherwise involve
the Administrative Agent or such Lender, as the case may be, or (y) any other
Person that is not a Governmental Authority, notify Thermo Electron of any
request for the disclosure of any such non-public information so as to provide
Thermo Electron with the reasonable opportunity to obtain a protective order or
other comparable relief.

                           Five-Year Credit Agreement

<PAGE>

                                                                 Schedule 1.1(b)

                             Mandatory Cost Formulae

          1. The Mandatory Cost is an addition to the interest rate to
          compensate Lenders for the cost of compliance with (a) the
          requirements of the Bank of England and/or the Financial Services
          Authority (or, in either case, any other authority which replaces all
          or any of its functions) or (b) the requirements of the European
          Central Bank.

          2. On the first day of each Interest Period (or as soon as possible
          thereafter) the Administrative Agent shall calculate, as a percentage
          rate, a rate (the "Mandatory Cost Rate") for each Lender, in
          accordance with the paragraphs set out below. The Mandatory Cost will
          be calculated by the Administrative Agent as a weighted average of the
          Lenders' Mandatory Cost Rates (weighted in proportion to the
          percentage participation of each Lender in the relevant Loan) and will
          be expressed as a percentage rate per annum.

          3. The Mandatory Cost Rate for any Lender lending from a Facility
          Office in a Participating Member State will be the percentage notified
          by that Lender to the Administrative Agent. This percentage will be
          certified by that Lender in its notice to the Administrative Agent to
          be its reasonable determination of the cost (expressed as a percentage
          of that Lender's participation in all Loans made from that Facility
          Office) of complying with the minimum reserve requirements of the
          European Central Bank in respect of loans made from that Facility
          Office.

          4. The Mandatory Cost Rate for any Lender lending from a Facility
          Office in the United Kingdom will be calculated by the Administrative
          Agent as follows:

          In relation to a Sterling Loan:

                  AB + C(B - D) + E x 0.01
                  -------------------------
                                                     Per cent. per annum
                      100 - (A + C)

          in relation to a Loan in any currency other than Sterling:

                  E x 0.01
                  ---------
                                                     Per cent. per annum
                      300

Where:

          A    is the percentage of Eligible Liabilities (assuming these to be
               in excess of any stated minimum) which that Lender is from time
               to time required to maintain as an interest free cash ratio
               deposit with the Bank of England to comply with cash ratio
               requirements.
<PAGE>

          B    is the percentage rate of interest (excluding the applicable
               Margin and the Mandatory Cost and, if the Loan is an overdue
               amount, the additional rate of interest specified in Section
               2.10(c)) payable for the relevant Interest Period on the Loan.

          C    is the percentage (if any) of Eligible Liabilities which that
               Lender is required from time to time to maintain as interest
               bearing Special Deposits with the Bank of England.

          D    is the percentage rate per annum payable by the Bank of England
               to the Administrative Agent on interest bearing Special Deposits.

          E    is designed to compensate Lenders for amounts payable under the
               Fees Rules and is calculated by the Administrative Agent as being
               the average of the most recent rates of charge supplied by the
               Reference Lender to the Administrative Agent pursuant to
               paragraph 7 below and expressed in pounds per (pound)1,000,000.

          5.   For the purposes of this Schedule:

          (a)  "Eligible Liabilities" and "Special Deposits" have the meanings
               given to them from time to time under or pursuant to the Bank of
               England Act 1998 or (as may be appropriate) by the Bank of
               England;

          (b)  "Facility Office" means the office or offices notified by a
               Lender to the Administrative Agent in writing on or before the
               date it becomes a Lender (or, following the date, by not less
               than five Business Days' written notice) as the office or offices
               through which it will perform its obligations under this
               Agreement;

          (c)  "Fees Rules" means the rules on periodic fees contained in the
               FSA Supervision Manual or such other law or regulation as may be
               in force from time to time in respect of the payment of fees for
               the acceptance of deposits;

          (d)  "Fee Tariffs" means the fee tariffs specified in the Fees Rules
               under the activity group A.I. Deposit acceptors (ignoring any
               minimum fee or zero rated fee required pursuant to the Fee rules
               but taking into account any applicable discount rate);

          (e)  "Participating Member State" means any member state of the
               European Communities that adopts or has adopted the Euro as its
               lawful currency in accordance with legislation of the European
               Community relating to Economic and Monetary Union; and

          (f)  "Reference Lender" means ABN AMRO Bank N.V., London branch

          (g)  "Tariff Base" has the meaning given to it in, and will be
               calculated in accordance with, the Fees Rules.
<PAGE>

          6. In application of the above formulae, A, B, C and D will be
          included in the formulae as percentages (i.e. 5 per cent. will be
          included in the formula as 5 and not as 0.05). A negative result
          obtained by subtracting D from B shall be taken as zero. The resulting
          figures shall be rounded to four decimal places.

          7. If requested by the Administrative Agent or Thermo Electron, the
          Reference Lender shall, as soon as practicable after publication by
          the Financial Services Authority, supply to the Administrative Agent
          and Thermo Electron, the rate of charge payable by the Reference
          Lender to the Financial Services Authority pursuant to the Fees Rules
          in respect of the relevant financial year of the Financial Services
          Authority (calculated for this purpose by the Reference Lender as
          being the average of the Fee Tariffs applicable to the Reference
          Lender for that financial year) and expressed in pounds per
          (pound)1,000,000 of the Tariff Base of the Reference Lender.

          8. Each Lender shall supply any information required by the
          Administrative Agent for the purpose of calculating its Mandatory Cost
          Rate. In particular, but without limitation, each Lender shall supply
          the following information on or prior to the date on which it becomes
          a Lender: the jurisdiction of its Facility Office; and any other
          information that the Administrative Agent may reasonably require for
          such purpose.

               Each Lender shall promptly notify the Administrative Agent of any
          change to the information provided by it pursuant to this paragraph.

          9. The percentages of each Lender for the purpose of A and C above and
          the rates of charge of the Reference Lender for the purposes of E
          above shall be determined by the Administrative Agent based upon the
          information supplied to it pursuant to paragraphs 7 and 8 above and on
          the assumption that, unless a Lender notifies the Administrative Agent
          to the contrary, each Lender's obligations in relation to cash ratio
          deposits and Special Deposits are the same as those of a typical bank
          from its jurisdiction of incorporation with a Facility Office in the
          same jurisdiction as its Facility Office.

          10. The Administrative Agent shall have no liability to any person if
          such determination results in a Mandatory Cost Rate which over or
          under compensates any Lender and shall be entitled to assume that the
          information provided by any Lender including the Reference Lender
          pursuant to paragraphs 3, 7 and 8 above is true and correct in all
          respects.

          11. The Administrative Agent shall distribute the additional amounts
          received as a result of the Mandatory Cost to the Lenders on the basis
          of the Mandatory Cost Rate for each Lender based on the information
          provided by each Lender and the Reference Lender pursuant to
          paragraphs 3, 7 and 8 above.

          12. Any determination by the Administrative Agent pursuant to this
          Schedule in relation to a formula, the Mandatory Cost, a Mandatory
          Cost Rate or any amount payable to a Lender shall, in the absence of
          manifest error, be conclusive and binding on all parties to this
          Agreement.
<PAGE>

          13. The Administrative Agent may from time to time, after consultation
          with Thermo Electron, the Borrowers and the Lenders, determine and
          notify to all parties to this Agreement any amendments which are
          required to be made to this Schedule in order to comply with any
          change in law, regulation or any requirements from time to time
          imposed by the Bank of England, the Financial Services Authority or
          the European Central Bank (or, in any case, any other authority which
          replaces all or any of its functions) and any such determination
          shall, in the absence of manifest error, be conclusive and binding on
          all parties to this Agreement.

                           Fixed Rate Promissory Note
                                (Multiple Loans)
                               New York, New York

                                                                    May 27, 2005

         For value received, the undersigned (the "Borrower") unconditionally
promises to pay to the order of JPMORGAN CHASE BANK, NATIONAL ASSOCIATION (the
"Bank"), at its office located at 270 Park Avenue, New York, New York 10017, the
principal amount of each loan made by the Bank to the Borrower and outstanding
under this Note on the maturity date(s) as evidenced by the Bank's records as
provided in the fifth paragraph hereof.

         The Borrower promises to pay interest on the unpaid balance of the
principal amount of each such loan for each day outstanding at a fixed rate per
annum equal to the rate as evidenced in the Bank's records as provided in the
fifth paragraph hereof; provided that principal and (to the extent permitted by
law) interest not paid when due (whether at stated maturity, by acceleration or
otherwise) shall bear interest for each day overdue at a variable rate per annum
equal to: (a) the higher of: (i) the Federal Funds Rate plus 1/2 of 1% and (ii)
the Prime Rate; plus (b) 2%. "Federal Funds Rate" means, for any day, the rate
per annum equal to the weighted average of the rates on overnight Federal funds
transactions as published by the Federal Reserve Bank of New York for such day
(or for any day that is not a banking day in New York City, for the immediately
preceding banking day). "Prime Rate" means, for any day, that rate of interest
from time to time announced by the Bank at its principal office as its prime
rate, as in effect for such day in accordance with announcements by the Bank of
changes in such rate. Interest shall be calculated on the basis of a year of 360
days and paid for the actual number of days elapsed (including the first day but
excluding the last day). Interest on each loan shall be due and payable at the
maturity thereof (and quarterly, if requested by the Bank); provided, however,
that interest accruing on any amount not paid when due shall be payable upon
demand. In no case shall the interest on this Note exceed the maximum amount
which the Bank may charge or collect under applicable law.

         Each loan hereunder may be prepaid in whole or in part, provided that
accrued and unpaid interest is paid on the date of such prepayment, together
with any compensation payable in accordance with the following. If there is any
payment (whether by voluntary prepayment, acceleration or otherwise) of a loan
under this Note on a date other than the scheduled maturity date set forth in
the first paragraph hereof, then the Borrower will pay the Bank on demand such
amount as will be sufficient in the reasonable opinion of the Bank to compensate
it for any loss, cost or expense which the Bank determines is attributable
thereto. Without limiting the foregoing, such compensation shall include an
amount equal to redeployment costs or expenses which the Bank determines are
attributable thereto and any costs, expenses or compensation payable to lenders
holding an interest in the loan.

         All payments under this Note shall be made without set-off or
counterclaim in lawful money of the United States of America and in immediately
available funds at the Bank's principal office specified above. If any loan
evidenced by this Note becomes due and payable on a day which is not a banking
day in New York City, the maturity of such loan shall be extended to the next
succeeding banking day, and interest shall be payable for such extension on such
loan at the rate of interest specified in this Note. The Bank may (but shall not
be obligated to) debit the amount of any payment which is not made when due to
any deposit account of the Borrower with the Bank.

         The date, amount, rate of interest and maturity date of each loan under
this Note and each payment of principal, loan(s) to which such principal is
applied (which Borrower may designate in writing in advance or at the time of
such payment provided Borrower is not then in default or would not thereby be in
default in which case such application shall be at the discretion of the Bank)
and the outstanding principal balance of loans shall be recorded by the Bank on
its books and, at the discretion of the Bank prior to any transfer of this Note
or at any other time, may be endorsed by the Bank on a schedule. Any such
endorsement shall be conclusive in the absence of manifest error.

         If any of the following events of default shall occur and be
continuing: (a) the Borrower fails to pay any liability to the Bank under this
Note when due and payable; (b) the Borrower shall breach any material covenant
in this Note or other document delivered in connection with this Note (this Note
and any such document being a "Facility Document") or any material
representation or warranty in any Facility Document or any certificate, opinion,
financial or other statement delivered in connection with a Facility Document
shall prove to be false or inaccurate in any material respect when made; (c) the
Borrower shall fail to pay any other Indebtedness (as that term is currently
defined in the credit agreement identified in the immediately following clause)
of Borrower in aggregate principal amount in excess of $10,000,000 when due and
payable beyond any applicable grace period, or one or more judgments in the
aggregate amount of $10,000,000 or more (not fully covered by insurance as to
which the relevant insurance company has acknowledged coverage) are entered
against the Borrower which have not been vacated, discharged, satisfied, stayed
or bonded pending appeal within 30 days from the entry thereof; (d) an Event of
Default shall occur under the Five Year Credit Agreement dated as of December
17, 2004 among the Borrower and the several lenders from time to time parties
thereto (as same may be amended, supplemented, renewed or restated from time to
time) and, so long as the Bank is a party to such credit agreement, such default
shall not have been waived by the lenders party thereto, provided that if such
credit agreement is repaid, expires or terminates, or the Bank ceases to be a
party thereto, this clause shall be based upon the terms of such credit
agreement as it existed immediately prior to such event; (e) the Borrower shall
become insolvent (however evidenced) or shall seek any relief under any
bankruptcy or similar law of any jurisdiction (or any person shall seek such
relief against the Borrower, provided that if Borrower promptly contests such
proceeding, it shall not be an event of default unless (A) an order for relief
or similar adjudication is entered, or (B) such proceeding remains pending 60
days of the commencement thereof); (f) any Facility Document shall at any time
cease to be in full force and effect or its validity or enforceability shall be
disputed or contested by the Borrower or any person controlled by the Borrower;
THEN, if the Bank shall elect by notice to the Borrower, the unpaid principal
amount of this Note, together with interest and any other amounts due hereunder
shall become forthwith due and payable; provided that in the case of an event of
default under (e) above, such amounts shall automatically become due and payable
without any notice or other action by the Bank.

         The Borrower waives presentment, notice of dishonor, protest and any
other formality with respect to this Note, other than notices expressly provided
for herein.

         The Borrower shall reimburse the Bank on demand for all reasonable
costs, expenses and charges (including, without limitation, reasonable fees and
charges of external counsel for the Bank) in connection with the enforcement of
this Note after default.

         This Note shall be binding on the Borrower and its successors and
assigns and shall inure to the benefit of the Bank and its successors and
assigns; provided that the Borrower may not delegate any obligations hereunder
without the prior written consent of the Bank.

         THIS NOTE SHALL BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK. THE
BORROWER CONSENTS TO THE NONEXCLUSIVE JURISDICTION AND VENUE OF THE STATE OR
FEDERAL COURTS LOCATED IN THE CITY OF NEW YORK. SERVICE OF PROCESS BY THE BANK
IN CONNECTION WITH ANY SUCH DISPUTE SHALL BE BINDING ON THE BORROWER IF SENT TO
THE BORROWER BY REGISTERED MAIL AT THE ADDRESS SPECIFIED BELOW. THE BORROWER
WAIVES ANY RIGHT THE BORROWER MAY HAVE TO JURY TRIAL.
