2. THE FACILITIES

(A)    The Banks agree to make available through their respective Lending
Offices to the Borrower upon the terms and subject to the conditions hereof a
revolving credit facility in the maximum aggregate principal amount of DM
195,000,000 (Deutsche Mark one hundred and ninety five million) or its
equivalent from time to time in Optional Currencies which is divided in (i) a
Tranche A in the amount of the DM-equivalent of USD 45,000,000 (or if lower,
the USD-equivalent of DM 195,000,000), and (ii) a Tranche B in the amount
equal to the difference between DM 195,000,000 and the Amount of Tranche A as
determined by the Agent in accordance with Article 4 (B) reduced by the
amount of the Acquired Financial Indebtedness (if any).

(B)    Each Bank (except Deutsche Bank Luxembourg S.A.) and Deutsche Bank AG,
Reutlingen Branch, agrees to make available an Ancillary Facility to the
Borrower in the amount set out for each Bank individually in the Sixth
Schedule and the aggregate amount of all such Ancillary Facilities will at no
time exceed an amount of DM 85,000,000 or its equivalent. The Ancillary
Facilities may only comprise facilities for the issue of guarantees, security
indemnity (or other commitment designed to assure any creditor against any
loss), trade or stand-by letters of credit, overdrafts, short term loans,
automated payment, cheque drawing and other current account facilities,
interest rate swaps or cross-currency swaps or forward sale or purchase
contracts or other form of interest or currency hedging transactions and each
Bank undertakes and warrants to the other Banks that the terms and conditions
governing the respective Ancillary Facility to which it is party shall have
to the extent legally possible the same terms and conditions as the terms and
conditions hereof.

(C)    The Facilities shall be made available severally by each Bank (and
Deutsche Bank AG, Reutlingen Branch respectively) in the amount of its Total
Commitment (and in the case of Deutsche Bank AG, Reutlingen Branch, its
commitment set out in the Sixth Schedule) and each Bank shall participate in
each Advance to be made under the Revolving Credit Facility in the proportion
which its Revolving Credit Facility Commitment bears to the amount of the
Revolving Credit Facility.

(D)    The failure of any Bank (and Deutsche Bank AG, Reutlingen Branch
respectively) to perform its obligations hereunder shall neither affect the
obligations of the Agent or the other Banks (and Deutsche Bank AG, Reutlingen
Branch respectively) towards the Borrower nor the obligations of the Borrower
towards the Agent or any other Bank (and Deutsche Bank AG, Reutlingen Branch
respectively), nor shall the Agent or any other Bank (and Deutsche Bank AG,

<PAGE>

Reutlingen Branch respectively) be liable for the failure of such Bank (and
Deutsche Bank AG, Reutlingen Branch respectively) to perform its obligations
hereunder.

(E)    The obligations of the Banks (and Deutsche Bank AG, Reutlingen Branch
respectively) hereunder, and the rights of the Agent and the Banks (and
Deutsche Bank AG, Reutlingen Branch respectively) hereunder, shall be
several. The amounts outstanding at any time hereunder from the Borrower to
any of the Banks (and Deutsche Bank AG, Reutlingen Branch respectively), the
Arrangers or the Agent shall be a separate and independent debt and each such
party shall be entitled to protect and enforce its rights arising out of this
Agreement and the Ancillary Facilities independently of any other party and
it shall not be necessary for any other party hereto to be joined by an
additional party in any proceedings for this purpose.

(F)    Immediately following the Commencement Date the Facilities shall be
re-denominated in EURO and all DM-amounts set out in paragraphs A and B shall
be the countervalue of such DM-amount. Each such EURO-countervalue shall be
determined by the Agent on the basis of the official DM/EURO conversion rate
set by the European Council on the Commencement Date pursuant to Article 109L
sub-paragraph 4 first sentence of the Treaty. The First Schedule, the Sixth
Schedule and sub-paragraphs (A) and (B) shall be adjusted accordingly

(G)    In the case that any bank chosen by the Borrower shall be willing to
become a bank hereunder the parties hereto will consider an amendment of this
Agreement to the effect that such bank shall become a Bank hereunder bearing
a Revolving Credit Facility Commitment in the maximum amount of DM 15,000,000
and an Ancillary Facilities  Commitment of a maximum of DM 5,000,000.

3. PURPOSE

(A)    Save to the provisions of Article 4 (A) the Borrower shall apply the
amounts raised by it under the Revolving Credit Facility and/or the Ancillary
Facilities (a) to the extent raised under Tranche A, for the refinancing and
replacement of the DLJ Loan or any other facility that has refinanced or
replaced such DLJ Loan in accordance with the provisions thereof, and (b) in
any case other than pursuant to subclause (a) above, an amount of
approximately DM 51,000,000 or its equivalent for the acquisition of all
shares in the Guarantor and ATE from WGMH and (c) for the refinancing of the
Bilateral Facilities and (d) for the general financing requirements of it and
any of its subsidiaries.

<PAGE>

(B)    Without prejudice to the obligations of the Borrower under paragraph (A),
neither the Arrangers, the Agent and the Banks nor any of them shall be
obliged to concern themselves with the application of amounts advanced or
raised hereunder.

4. CONDITIONS PRECEDENT, NOTICE OF BORROWING AND
   DETERMINATION OF TRANCHE B

(A)    Subject to:

(1)    all representations and warranties listed in Article 18 being true and
       correct on and as of the date on which an Advance is to be made
       hereunder; and

(2)    no Event of Early Repayment or an event which with the giving of
       notice, lapse of time or fulfilment of any other condition (all as
       provided for herein) would constitute an Event of Early Repayment
       having occurred; and

(3)    the receipt by the Agent of a Notice of Borrowing duly completed, such
       Notice of Borrowing to be received by the Agent not later than at
       11.00 a.m. on the fourth Business Day prior to the date on which the
       relevant Advance is to be made hereunder and not later than one month
       before the Final Maturity Date; and

(4)    the total number of Advances which have been made hereunder and have
       not, or will have not as of the proposed drawdown date of the relevant
       Advance, fallen due for repayment is not more than fifteen; and

(5)    the proposed amount of the Advances being an amount which when
       aggregated with the amounts of all previous Advances then outstanding
       (including any other Advances to be made on or before the proposed
       date for the making of such Advances but excluding any Advances
       respectively to be repaid on or before the proposed date for the
       making of such Advances) shall not be such as to cause the aggregate
       of all outstanding Advances to exceed the maximum amounts set out in
       Article 2 (A); and

(6)    the Loan not being outstanding in more than seven different currencies
       if the Advance is made; and

(7)    in the case of any Advance to be made under Tranche B the amount of
       the Tranche A Outstandings is 45,000,000 USD;

<PAGE>

the Borrower may draw Borrowing Amounts on any Business Day during the
Commitment Period, provided that the Borrower may not deliver a Notice of
Borrowing unless the Agent has confirmed to the Borrower and the Banks that
it has received within a period of six weeks after the date hereof all of the
documents listed in the Second Schedule and that each is, in form and
substance, satisfactory to the Agent.

(B)    If a drawdown shall be made under Tranche B the Agent shall determine
the Tranche B Amount one Business Day prior to the Interest Determination
Date by deducting the DM-equivalent of USD 45,000,000 and the Acquired
Financial Indebtedness (if any) from the amount of DM 195,000,000. If the
proposed Amount of the Advance does exceed the undrawn part of the Tranche B
Amount the Agent shall reduce the amount of such Advance accordingly and the
Agent shall notify the Borrower by 4:00 p.m. about such reduction.

(C)    Each Notice of Borrowing shall be irrevocable and the Borrower shall
be bound to borrow in accordance with such notice.

(D)    The Borrower shall not make any borrowings under the Ancillary
Facilities and none of the Banks and Deutsche Bank AG, Reutlingen Branch will
allow the Borrower to make such borrowings as long as the amount of the
Tranche A Outstandings is below USD 45,000,000. If the Revolving Credit
Facility Commitment is reduced in an amount of DM 100,000,000 in accordance
with Article 9 (D) and/or Article 11 (C) following an initial public offering
the parties will enter into negotiations with respect to the restrictions of
any borrowings under the Ancillary Facilities pursuant to this paragraph (D).

5. TERM OF ADVANCES

(A)    Each Advance shall have a term of one, two, three or six months or
such other period as may be agreed between the Borrower and the Agent (with
consent of the Banks), in each case as the Borrower shall select in the
Notice of Borrowing.

(B)    Notwithstanding the provisions of paragraph (A),

(1)    if the term of any Advance would otherwise end on a day which is not a
       Business Day, then such term or such interest period shall be extended
       to the next succeeding day which is a Business Day unless such next
       succeeding Business Day falls in another calendar month in which event
       such term shall end upon the immediately preceding Business Day;

<PAGE>

(2)    if the term of any Advance commences on the last Business Day in a
       calendar month or if there is no numerically corresponding day in the
       month in which that term ends, that term shall end on the last
       Business Day in that later month; and

(3)    if the term of any Advance would otherwise extend beyond the Final
       Maturity Date, it shall end on the Final Maturity Date.

6. INTEREST

(A)    The Borrower shall pay to the Agent for account of the Banks on the
Maturity Date of any Advance the interest on the amount of such Advance
accrued for the respective period (unless the term is longer than six months,
then interest shall be payable in semi-annual intervals and at the end of the
relevant term).

(B)    The rate of interest applicable to each Advance during its term shall
be the Interbank Rate increased by the Margin.

(C)    Interest payable pursuant to this Agreement shall be calculated on the
basis of the actual number of days elapsed and a 360-day-year or, where
market practice differs, 365 days or otherwise in accordance with market
practice.

(D)    Each determination of an interest rate made by the Agent under this
Agreement shall be promptly notified by the Agent to the Borrower and each
Bank.

7. CURRENCY OPTION

(A)    The Borrower may request in any Notice of Borrowing that the Advance
to which such Notice of Borrowing relates be denominated in a specified
Optional Currency and, if the Borrower shall so request and subject to the
following provisions of this Article, the relevant Advance shall be
denominated in the Optional Currency so specified.

(B)    Notwithstanding the provisions of paragraph (A), if any Bank
determines that deposits in the specified Optional Currency (other than USD)
are not or will not be available to it in the relevant amount and for the
relevant period in the Interbank Market, it may give notice thereof to the
Agent not later than 1:00 p.m. on the third Business Day preceding the date
of the proposed Advance.

<PAGE>

(C)    If the Agent receives a notification pursuant to paragraph (B) the
relevant Advance shall

(1)    if the Borrower has given instruction to that effect in the Notice of
       Borrowing, not be made in the specified Optional Currency but shall
       instead be made available in DM (or, after the Commencement Date,
       EURO), the amount of DM or EURO to be so advanced by the Banks being
       the Original Currency Amount specified in the relevant Notice of
       Borrowing; or

(2)    if the Borrower has given instruction to that effect in the Notice of
       Borrowing, not be made in the specified Optional Currency but shall
       instead be made available in USD, the amount of USD to be so advanced
       by the Banks being the Original Currency Equivalent; or

(3)    if the Borrower has failed to give any instruction as referred to in
       (1) or (2) above, not be made.

The Agent shall notify each Bank and the Borrower by 4:00 p.m. on the third
Business Day preceding the date of the proposed Advance of the receipt of any
such notice from a Bank as is referred to in paragraph (B) and, in the case
of (1) or (2) above, of the amount in DM, EURO, or, as the case may be, USD,
to be advanced by each Bank or in case of (3) above that such proposed
Advance shall not be made.

(D)    Notwithstanding the foregoing provisions of this Article, if any such
event as is described in paragraph (E) shall occur the Agent may (and shall,
if so instructed by the Majority Banks), at any time before, or not later
than 9:00 a.m. on the date on which an Advance would otherwise fall to be
made in an Optional Currency, give notice to the Borrower to the effect that
in consequence of such event it will not be possible for such Advance to be
denominated in the Optional Currency in question, in which case such Advance
shall then not be made at all and the Borrower shall pay to each Bank such
amount as is necessary to compensate such Bank for any and all losses and
costs incurred by it in liquidating and/or employing amounts borrowed or
contracted for, and/or in terminating or unwinding any contract entered into,
in order to fund its participation in the proposed Advance.

(E)    The events referred to in paragraph (D) are such changes in national
or international financial, political or economic conditions or currency
exchange rates or exchange controls as (in any such case) would, in the
reasonable opinion of the Agent (if feasible, after consultation with the
Borrower and the Reference Banks), make it impracticable for the Advance (or
the relevant part thereof) to be denominated in the Optional Currency in
question.

<PAGE>

(F)    If an Advance is to be made available in an Optional Currency, each
Bank through the Agent will make available to the Borrower the Original
Currency Equivalent of such Advance.

8. SUBSTITUTE BASIS

(A)    If, in relation to an Advance:

(1)    the Agent determines that at or about 11:00 a.m. on the Interest
       Determination Date for the relevant term in respect of such Advance
       (a) none or only one of the Reference Banks was being offered by prime
       banks in the Interbank Market deposits in the relevant currency for
       the proposed duration of such term or (b) by reason of circumstances
       affecting the Interbank Market generally such deposits are not
       available to banks in such market; or

(2)    before the close of business in Luxembourg on the Interest
       Determination Date for such term the Agent has been notified in
       writing by each Bank of a group of Banks to whom in aggregate
       thirty-five per cent. or more of the Original Currency Amount of the
       Loan is (or, if such Advance were then made, would be) owed that the
       Interbank Rate as determined by the Agent does not reflect its cost of
       obtaining such deposits;

then the Agent shall as soon as practicable give notice of such determination
to the Borrower and each Bank.

(B)    If the Agent gives notice pursuant to paragraph (A) (1) then if such
notice is given with respect to an Advance to be made, such Advance shall not
be made and in any case the Agent shall negotiate with the Borrower with a
view to agreeing an alternative basis (whether an alternative method of
fixing the rate of interest or (in the case of Advances to be made) an
alternative term or an alternative currency) for such Advance. Any
alternative basis agreed in writing within 30 days of the Agent's
notification of the event in question by the Agent (with the consent of all
the Banks) and the Borrower shall take effect in accordance with its terms
and the Borrower may make further requests for the making of Advances on such
alternative basis (subject as herein provided) whilst the circumstances
referred to under paragraph (A) (1) continue to exist. After the Agent has
determined that the circumstances referred to under paragraph (A) (1) have
ceased to exist, the rate of interest in respect of subsequent Advances or
(as the case may be) subsequent Interest Periods shall be the Interbank Rate
plus the Margin calculated in accordance with the provisions of this
Agreement.

<PAGE>

(C)    If the Agent gives notice pursuant to paragraph (A) (2), the Advance
shall be made and the Agent shall then negotiate with the Borrower with a
view to agreeing an alternative basis for fixing the rate of interest payable
on the relevant Advance. Any alternative basis agreed in writing within 10
days of the Agent's notification of the event in question by the Agent (with
the consent of all the Banks) and the Borrower shall take effect in
accordance with its terms and the Borrower may make further requests for the
making of Advances on such alternative basis (subject as herein provided)
whilst the circumstances referred to under paragraph (A) (2) continue to
exist, provided that if such alternative basis is not agreed, each Bank's
share of the relevant Advance(s) shall bear interest at the rate per annum
determined by the Agent as being the sum of (i) the cost to such Bank (as
certified to the Agent with a copy to the Borrower) of funding its share of
such Advance from whatever sources it may, in the ordinary course of its
business, reasonably select (expressed as a rate per annum) and (ii) the
Margin. After the Agent has determined that the circumstances referred to
under paragraph (A) (2) have ceased to exist, the rate of interest in respect
of subsequent Advances shall be the Interbank Rate plus the Margin calculated
in accordance with the provisions of this Agreement.

9. REPAYMENT AND PREPAYMENT

(A)    The amount of each Revolving Credit Advance shall be repaid by the
Borrower on its Maturity Date. Any amount repaid pursuant to this paragraph
(A) may, subject to the provisions of this Agreement, be reborrowed.

(B)    The Borrower shall not repay or prepay all or any part of the Advances
except in accordance with the terms of this Agreement.

(C)    The Borrower may, by notice to the Agent not later than on the tenth
Business Day before the proposed date for the making of such prepayment,
prepay the whole of any Advance or any part (being a Borrowing Amount) on a
day other than the Maturity Date relating thereto provided that such
prepayment is made together with the payment of accrued interest on such
Advance or part thereof to be prepaid and any amount payable by the Borrower
under Article 14 (D).

(D)    To the extent the Revolving Loan exceeds the amount of DM 95,000,000
(the "EXCEEDING AMOUNT") the Borrower shall apply any net proceeds from any
monies raised by the Group in the national or international equity or capital
markets (via an IPO, a private equity placement, a public or private bond
offering or otherwise) to prepay the Exceeding Amount. Any such amounts to be
applied towards the prepayment of the Revolving Loan shall be paid to the
Agent and the Agent shall deposit such amounts on behalf of the Banks in an
interest bearing account and shall (save to the provisions of Article 10) be
applied (including accrued interest

<PAGE>

thereon) on the last day of the then relevant current Interest Period towards
the prepayment of any outstanding Advances PRO RATA.

(E)    The Borrower shall apply an amount equal to the net proceeds resulting
from (i) a disposal of assets made under a sale and lease back transaction by
any member of the Group permitted under Article 19 (D) (other than proceeds
from sale-lease-back transactions applied towards the repayment of existing
debt in accordance with Article 19 (D)(4)) and (ii) the sale of a certain
subsidiary to be agreed upon with the Banks permitted under Article 19 (E)
towards the repayment of the Revolving Loan.

(F)    Any amount prepaid pursuant to paragraph (C) may, subject to the
provisions of this Agreement, be reborrowed. Amounts prepaid pursuant to
paragraph (D) or repaid pursuant to paragraph (E) may not be reborrowed and
any such payment shall reduce the Revolving Credit Facility Commitment of
each Bank rateably.

10. MAINTENANCE OF DLJ LOAN REFINANCING

Any prepayment made hereunder shall be made in a manner that any amount
raised by the Borrower under Tranche A for the repayment, replacement and /or
refinancing of the DLJ Loan or any loans the proceeds of which were used for
the repayment, replacement and/or refinancing of the DLJ Loan shall save to
make any agreement between parties hereto following any negations in
accordance with Article 4 (D) only be prepaid if (i) there are no other
outstandings under this Agreement and the Ancillary Facilities and (ii) the
Borrower has cancelled (a) any commitment of the Banks for future borrowings
under this Agreement and (b) any commitment of the relevant Banks and
Deutsche Bank AG, Reutlingen Branch respectively for future borrowings under
the Ancillary Facilities.

11. CANCELLATION

(A)    Unless otherwise agreed between the Borrower and the Banks (and
Deutsche Bank AG, Reutlingen Branch respectively), any Commitment of any Bank
(and Deutsche Bank AG, Reutlingen Branch respectively) made hereunder will
automatically cease to exist if the Agent has not received all of the
documents listed in the Second Schedule within a period of six weeks after
the date hereof;

(B)    The Borrower may, by giving to the Agent not less than ten Business
Days' prior written notice to that effect, cancel the whole or any part
(being a Borrowing Amount) of the then

<PAGE>

undrawn part of the Revolving Credit Facility Commitments. Any such
cancellation shall reduce the Revolving Credit Facility Commitment of each
Bank rateably.

(C)    The Borrower shall cancel the then undrawn part of the Revolving
Credit Facility Commitment in an amount equal to (i) the amount of any
proceeds resulting from a disposal of assets made under a sale and lease back
transaction by any member of the Group permitted under Article 19 (D) (other
than proceeds from sale-lease-back transactions applied towards the repayment
of existing debt in accordance with Article 19 (D)(4)) and the sale of the
certain subsidiary permitted in accordance with Article 19 (E) if any such
amount is not applied for repayment in accordance with Article 9 (E), and/or
(ii) an amount of up to DM 100,000,000 out of any net proceeds from any
monies raised by the Group in the national or international equity or capital
markets (via an IPO, a private equity placement, a public or private bond
offering or otherwise) if any such amount is not applied for prepayment in
accordance with Article 9 (D).

(D)    If any Bank claims a payment or indemnification from the Borrower
under Article 13 (A)(1), Article 16 (A) or Article 16 (B), the Borrower may,
within thirty days thereafter and by not less than fifteen days' prior notice
to the Agent, cancel such Bank's Commitment whereupon such Bank shall cease
to be obliged to participate in further Advances and its Commitment shall be
reduced to zero.

(E)    Any notice of cancellation given by the Borrower pursuant to
paragraphs (A) through (D) shall be irrevocable and shall specify the date
upon which such cancellation is to be made and (in case of a cancellation
pursuant to paragraph (B) and (C)) the amount of such cancellation and in any
case Tranche B is deemed to be cancelled first.

12. EVIDENCE OF DEBT

(A)    Each Bank shall maintain, in accordance with its usual practice,
accounts evidencing the amounts from time to time lent by and owing to it
hereunder.

(B)    The Agent shall maintain in its books a control account or accounts in
which shall be recorded (i) the amounts outstanding under Tranche A and
Tranche B and each Bank's share therein, (ii) the amount of the Tranche A
Outstandings, and (iii) the amount of any principal or interest or other sums
due or to become due from the Borrower to the Banks hereunder and each Bank's
share therein and (iv) the amount of any sum received or recovered by the
Agent hereunder and each Bank's share therein.

<PAGE>

(C)    In any legal action or proceedings arising out of or in connection
with this Agreement the entries made in the accounts maintained pursuant to
paragraphs (A) and (B) shall save for manifest errors give PRIMA FACIE
evidence of the existence and amounts of the obligations of each of the
Obligors therein recorded.

13. PAYMENTS

(A)    All amounts payable under this Agreement by either Obligor including
amounts payable under this paragraph (A), shall be paid in full without
set-off or counterclaim or right of retention or other restrictions and free
and clear of and without any deduction or withholding for or on account of
any taxes or any charges or otherwise. In the event that either of the
Obligors is required by law to make any such deduction or withholding from
any payment hereunder then:

(1)    such Obligor shall, save where a Bank has failed to comply with
       paragraph (G) due to reasons not beyond such Bank's control, forthwith
       pay to the Agent for account of the respective Bank or, as the case
       may be, the Agent such additional amount as will result in the
       immediate receipt by such Bank or, as the case may be, the Agent of
       the full amount (free from any liability in respect of any such
       deduction or withholding) which would have been received hereunder had
       no such deduction or withholding been made; and

(2)    such Obligor shall pay the full amount required to be deducted or
       withheld to the relevant taxation or other authority within the time
       allowed for such payment and shall promptly, but in any case within 20
       days, forward to the Agent official receipts of the relevant taxation
       or other authority or other evidence acceptable to such Bank to the
       extent available from such relevant authority or, as the case may be,
       the Agent of the amount deducted or withheld as aforesaid.

(B)    All payments of principal and/or interest in respect of an Advance to
be made by either of the Obligors under this Agreement shall be made in the
currency of that Advance in mmediately available funds not later than 10:00
a.m. (local time at the place of payment) on the date upon which the relevant
payment is due (i) in case such amount is denominated in DM to the account
no. 400/8716961 of the Agent with Commerzbank Aktiengesellschaft, Frankfurt
am Main (or to such other account as the Agent may from time to time
designate by timely written notice to the relevant Obligor) or (ii) in case
such amount is denominated in any other currency to such account of the Agent
with such bank as the Agent may have timely specified for this purpose.

(C)    All payments to be made by the Agent under this Agreement to the
Borrower shall be made in the currency of the Advance not later than 10:00
a.m. (local time at the place of

<PAGE>

payment) on the date upon which the relevant payment is due and be remitted
to such account and bank as the Borrower may from time to time designate by
written notice to the Agent.

(D)    Each Bank shall make available to the Agent its portion of an Advance
to be made to the Borrower hereunder prior to 10:00 a.m. (local time at the
place of payment) on the date of the proposed borrowing by payment in the
currency of the Advance and in immediately available funds to such account as
the Agent may from time to time designate.

(E)    Except for payments received by the Agent for its account or for the
account of a specific Bank in accordance with this Agreement, the Agent shall
forthwith distribute in like funds and currency each payment received by it
for the account of the Banks rateably in proportion to their respective share
of the Revolving Loan respectively or, as the case may be, their respective
Revolving Credit Facility Commitment.

(F)    Where a sum is to be paid hereunder to the Agent for account of
another person pursuant to the provisions hereof, the Agent shall not be
obliged to make the same available to that other person until it has been
able to establish to its satisfaction that it has actually received such sum,
but if it makes the same sum available to that other person before it has
been able to establish to its satisfaction that it has actually received such
sum and it proves to be the case that it has not actually received such sum,
then the person to whom such sum was so made available shall on request
(which shall be made as soon as practicable after the Agent has established
that it has not actually received that sum) refund the same to the Agent
together with an amount sufficient to indemnify the Agent against any
reasonable cost or loss it may have suffered or incurred by reason of its
having paid out such sum prior to its having received such sum.

(G)    Each Bank agrees that, upon request by the Obligor affected, it shall
deliver, as soon as it can do so in the ordinary course of business, to such
Obligor such relevant tax form(s) as may be required under the laws of the
Relevant Jurisdiction or under an applicable double taxation treaty to avoid
or reduce a deduction or withholding on payments as described in paragraph (A).

(H)    If and to the extent that any Obligor pays any additional amount under
paragraph (A), and any Bank receives or has been granted a credit against or
relief or remission for or repayment of any tax paid or payable by it (the
"TAX CREDIT") in respect of or calculated with reference to the deduction or
withholding in respect of which such additional amount has been paid, then
such Bank shall - to the extent that it can do so without prejudice to the
retention of such Tax Credit - pay to the relevant Obligor such amount as it
shall, in its opinion, determine to be attributable to the relevant deduction
or withholding, and any such payment to the relevant Obligor shall constitute
full and final settlement of any rights of reimbursement in respect of such
Tax Credit.

<PAGE>

It shall be each Bank's sole discretion (to be exercised in good faith) to
decide as to whether and how and when and to what extent to claim any Tax
Credit and no Bank shall be obliged to disclose any information as to its tax
affairs which it regards as proprietary or confidential and each Bank shall
be entitled to arrange and organize its tax and other affairs in any way it
thinks fit.

(I)    If, in respect of any Bank, circumstances arise which result or would
result in a claim for payment or a payment of an additional amount to it or
for its account pursuant to paragraph (A) (1), then, without in any way
limiting, reducing or otherwise qualifying the obligations of the Obligors
hereunder, such Bank shall promptly upon becoming aware of the same notify
the Agent thereof and shall, in consultation with the Agent and the Obligors
to the extent that it can do so without prejudice to its own position, take
such reasonable steps as may be open to it to mitigate or avoid the effects
of such circumstances, including the change of its Lending Office or the
transfer of its rights and obligations hereunder to another bank acceptable
to the Obligors and willing to participate in the Facilities provided that
such Bank shall be under no obligations to take any such action if, in such
Bank's BONA FIDE opinion, to do so may have any adverse effect upon its
business, operations or financial condition. No Bank shall be obliged to
disclose any information as to its tax affairs which it regards as
proprietary or confidential and each Bank shall be entitled to arrange and
organize its tax and other affairs in any way it thinks fit.

(J)    Save to the provisions of Article 10 the Agent may (notwithstanding
any appropriation of that payment by such Obligor) apply any payment received
from either Obligor towards the obligations of the Obligors hereunder in the
following order:

FIRST, in or towards payment of any unpaid costs and expenses of each of the
Agent and the Arrangers;

SECONDLY, in or towards payment pro rata of any accrued fees due but unpaid;

THIRDLY, in or towards payment pro rata of any accrued interest due but
unpaid;

FOURTHLY, in or towards payment pro rata of any principal due but unpaid; and

FIFTHLY, in or towards payment pro rata of any other sum due but unpaid.

(K)    Any payment hereunder falling due on a day which is not a Business Day
shall be payable on the next succeeding day which is a Business Day, unless
such next succeeding

<PAGE>

Business Day falls in another calendar month in which event such payment
shall be due on the immediately preceding Business Day.

14. DEFAULT INTEREST AND INDEMNITY

(A)    In the event of a failure of either of the Obligors to pay any sum
other than interest on the date on which such sum is due and payable pursuant
to this Agreement and irrespective of any notice by the Agent to such Obligor
in respect of such failure, such Obligor shall pay interest on such sum on
demand from the date of such failure up to the date of actual payment (as
well after as before judgement) at the rate, increased by the Margin plus one
per cent. (1 %), determined by the Agent to be the arithmetic mean (rounded
upwards, if necessary, to the nearest multiple of one sixteenth of one per
cent (1/16 %)) of the per annum rates, notified to the Agent by the Banks to
be those at which deposits in the currency of the unpaid sum for such period
as the Agent may select in its discretion (after consultation with the Banks)
are offered to each Bank by prime banks in the Interbank Market for value two
Business Days later as at 11:00 a.m. on the Business Day immediately
succeeding that on which the Agent becomes aware of the failure and, so long
as the failure continues, such rate shall be calculated on the same basis
thereafter. Interest accruing under this paragraph shall be due and payable
at the end of each period by reference to which it is calculated.

(B)    Without prejudice to the foregoing and irrespective of any notice by
the Agent to either of the Obligors in respect of such Obligor's failure to
make any payment when due, such Obligor shall indemnify the Agent and the
Banks against any other damages, losses or expenses (including losses
incurred in paying overdraft interest or in liquidating or employing deposits
from third parties acquired to make, fund or maintain the Loan or any part
thereof) which any of them may sustain or incur as a consequence of (i) the
failure by such Obligor to pay any sum when due and payable under this
Agreement, (ii) the occurrence of any Event of Early Repayment, or (iii) an
Advance requested in a Notice of Borrowing given by the relevant Obligor but
not being made by reason of the operation of any one or more of the
provisions hereof.

(C)    If any sum due from either of the Obligors under this Agreement or any
order or judgment given or made in relation hereto has to be converted from
the currency (the "FIRST CURRENCY") in which the same is payable hereunder
into another currency (the "SECOND CURRENCY") for the purpose of (i) making
or filing a claim or proof against such Obligor, (ii) obtaining an order or
judgement in any court or other tribunal or (iii) enforcing any order or
judgement given or made in relation hereto, such Obligor shall indemnify and
hold harmless each of the persons to whom such sum is due from and against
any damages or losses suffered as a result of any discrepancy between (a) the
rate of exchange used for such purpose to convert the

<PAGE>

sum in question from the first currency into the second currency and (b) the
rate or rates of exchange at which such person may in the ordinary course of
business purchase the first currency with the second currency upon receipt of
a sum paid to it in satisfaction, in whole or in part, of any such order,
judgement, claim or proof. The above indemnity shall constitute an
independent obligation of the Obligors separate from each of their other
obligations hereunder and shall apply irrespective of any indulgence granted
by the Agent or the Banks.

(D)    Any prepayment or repayment of principal made under this Agreement
shall, if made otherwise than on the Maturity Date relative to the amounts
prepaid or repaid, be made together with accrued interest thereon and such
additional amount as each Bank may certify as necessary to compensate it for
any damages or losses incurred or to be incurred by it in connection with
such prepayment or repayment (including loss of Margin and losses on account
of funds borrowed in order to make, fund or maintain its portion of the Loan
or any part thereof prepaid or repaid).

15. SET-OFF AND REDISTRIBUTION OF PAYMENTS

(A)    Each of the Obligors authorizes each Bank to apply any credit balance
to which such Obligor is entitled on any account of such Obligor with that
Bank in satisfaction of any sum due and payable from such Obligor to such
Bank hereunder but (following the termination of a grace period (if any))
unpaid; for this purpose, each Bank is authorized to purchase with the monies
standing to the credit of any such account such other currencies as may be
necessary to effect such application. No Bank shall be obliged to exercise
any right given to it by this paragraph (A) but if it does so it shall notify
the Agent and the relevant Obligor of such exercise.

(B)    If at any time the proportion received or recovered by any Bank or
Deutsche Bank AG, Reutlingen Branch (a "RECOVERING BANK") by way of set-off
or otherwise (other than through the Agent in accordance with Article 13 (E))
in respect of its portion of any amounts due from an Obligor to the Banks
under this Agreement or an Ancillary Facility to which such Recovering Bank
is a party is greater than the proportion thereof which the relevant
Recovering Bank would have received through the Agent if distributed in
accordance with Article 13 (E) or which such Recovering Bank is entitled to
receive under the relevant Ancillary Facility (the difference between the
amount received or recovered by the Recovering Bank and the amount which the
Recovering Bank would have received or recovered had the recovery been
received through the Agent if distributed in accordance with Article 13 (E)
or under the relevant Ancillary Facility respectively hereinafter called the
"EXCESS AMOUNT"), then:

<PAGE>

(1)    such Recovering Bank shall promptly notify the Agent and pay to the
       Agent an amount equal to the Excess Amount (the "SHARING PAYMENT")
       within three Business Days of such notification;

(2)    the Agent shall account for such payment to the Banks and Deutsche
       Bank AG, Reutlingen Branch respectively (excluding the Recovering Bank
       having received the Excess Amount) as if it were a payment by the
       relevant Obligor on account of the sum owed to the Banks under this
       Agreement and the Ancillary Facilities; and

(3)    to the extent that amounts received or recovered by a Recovering Bank
       resulted in the satisfaction of a Recovering Bank's claim hereunder or
       under the Ancillary Facility to which such Bank is party, but are
       allocated in accordance with this Article 15 to another Bank and
       Deutsche Bank AG, Reutlingen Branch respectively, the latter shall
       assign to the Recovering Bank the claims (or the part thereof) to
       which the amount is allocated.

(4)    If any part of the Sharing Payment received or recovered by a
       Recovering Bank becomes repayable and is repaid by such Recovering
       Bank, then each party which has received a share of such Sharing
       Payment pursuant to paragraph (2) shall, upon request of the Agent,
       pay to the Agent for account of such Recovering Bank an amount equal
       to its share of such Sharing Payment together with its proportionate
       share of any interest or other sum paid to such Obligor by the
       Recovering Bank in respect of the Sharing Payment and such Recovering
       Bank shall re-assign to the relevant Bank any claim assigned to it by
       such Bank pursuant to paragraph (3).

(5)    This Article 15 shall not apply if the Recovering Bank would not,
       after making any payment pursuant hereto, have a valid and enforceable
       claim against the relevant Obligor and sums recovered as a result of
       litigation started by a Bank to enforce its rights under this
       Agreement and resulting in an Excess Amount shall only be shared with
       such Banks that have joined in such litigation or commenced and
       diligently pursued separate litigation to enforce their rights under
       this Agreement and/or the Ancillary Facility to which such Bank is
       party.

16. CHANGE OF CIRCUMSTANCES

(A)    If:

(1)    by reason of any change or coming into force after the date hereof of
       law, regulation, treaty or official directive which any Bank or any
       holding company of such Bank is

<PAGE>

       required to comply with (whether or not having the force of law
       provided that in case of an official directive not having the force of
       law compliance must be customary in the ordinary course of business)
       or any change of the interpretation thereof by any authority charged
       with the administration or application thereof (including, for the
       avoidance of doubt, any such change or compliance in connection with
       the introduction of, changeover to or operation of the Euro):

       (a)    subjects any Bank (or any holding company of such Bank) to any
              tax with respect to payments of principal of or interest on its
              portion of any Advance or any other amount payable hereunder
              (other than a tax imposed or calculated by reference to the net
              income of such Bank or holding company); or

       (b)    changes the basis of taxation of payments to any Bank (or any
              holding company of such Bank) of principal of or interest on
              its portion of any Advance or of any other amount payable
              hereunder (other than a change in the rate of any tax imposed
              on or calculated by reference to the net income of such Bank or
              holding company of such Bank); or

       (c)    imposes, modifies or deems applicable any reserve and/or
              special deposit requirements against or in respect of assets or
              liabilities of, or deposits with or for the account of, or
              loans or credit extended by, any Bank (or any holding company
              of such Bank); or

       (d)    affects the manner in which a Bank (or any holding company of
              such Bank) allocates capital resources to its obligations
              hereunder; or

(2)    any Bank (or any holding company of such Bank) complies with any law,
       regulation or binding official request or directive from any applicable
       fiscal or monetary authority (whether or not having the force of law);

and as a result of any of the foregoing:

(a)    the cost to such Bank (or such holding company) of making, funding or
       maintaining its portion of any Advance or of maintaining its
       Commitment is increased; or

(b)    the amount of principal, interest or other amount payable hereunder to
       such Bank or the effective return to such Bank (or such holding
       company) hereunder is reduced; or

<PAGE>

(c)    such Bank (or any holding company of such Bank) makes any payment or
       forgoes any interest or other return on or calculated by reference to
       the gross amount of any sum receivable by such Bank from any of the
       Obligors hereunder,

then and in any such case:

(i)    upon demand from time to time the Borrower shall pay to the Agent for
       account of such Bank such amount as shall compensate such Bank or any
       such holding company for such increased cost (or such proportion of
       such cost as is, in such Bank's BONA FIDE opinion, attributable to the
       relevant Advance and its term respectively to such Bank's Revolving
       Credit Facility Commitment hereunder), reduction, payment or forgone
       interest or other return. A Bank entitled to make a claim pursuant to
       this paragraph shall notify the Agent of the event by reason of which
       it is so entitled whereupon the Agent shall notify the Borrower
       thereof. Such Bank shall submit to the Agent a certificate setting out
       reasonable details of the event giving rise to such compensation, the
       amount thereof and the manner in which it has been calculated and such
       certificate shall be forwarded promptly by the Agent to the Borrower,
       provided, however, that nothing herein shall require such Bank to
       disclose any confidential information relating to the organisation of
       its or its holding company's affairs; and

(ii)   the Borrower may prepay such Bank's portion of such Advance together
       with all interest accrued thereon and all fees and other amounts
       (including amounts payable under sub-paragraph (i) and Article 14 (D))
       payable to such Bank hereunder, on giving not less than fifteen days'
       prior written irrevocable notice to the Agent.

Notwithstanding the foregoing provisions of this Article 16, no Bank shall be
entitled to claim under paragraph (A) in respect of any amount which is
compensated for by the operation of paragraph (B).

(B)    If any sum payable by any Obligor hereunder whether in respect of
principal, interest or otherwise or any recipient of any such sum by reason
of its receiving such sum is or becomes subject at any time to taxation in
the Relevant Jurisdiction, such Obligor will indemnify such recipient in
respect of such tax liability so that such recipient receives or retains a
net sum equal to the sum it would have received or retained had there been no
such tax liability. In addition, such Obligor shall indemnify the Agent and
each Bank, respectively, against any present or future claim or liability for
taxes in the Relevant Jurisdiction imposed on any of them or on any agent,
branch, employee, intermediary, representative or representative office of
any of them

<PAGE>

only by virtue of the negotiation, preparation or execution of this
Agreement, the performance of any obligation hereunder or any entitlement to
or receipt of any payment hereunder.

(C)    Notwithstanding anything to the contrary herein contained, if any
change in law, regulation or treaty or in the binding and official
interpretation or application thereof by any authority charged with the
administration or application thereof shall make it unlawful for any Bank to
make, fund or maintain all or any of its portion of the Advances made or to
be made hereunder or to give effect to its obligations through its Lending
Office as contemplated hereby, such Bank may, by written notice thereof to
the Agent to be forwarded by the Agent to the Borrower declare that such
Bank's obligations shall be terminated forthwith (or if permitted on the
latest day allowed by such law, regulation or treaty) whereupon the Borrower
shall prepay forthwith (or if permitted by such law, regulation or treaty on
the next following Maturity Date in relation to such outstanding Advance)
such Bank's portion in any Advance outstanding together with all interest
accrued thereon and all fees and other amounts payable by it to such Bank
hereunder. Such Bank's obligations hereunder and its Revolving Credit
Facility Commitment shall be cancelled upon the Agent's receipt of such
notice.

(D)    If, in respect of any Bank, circumstances arise which result in an
increase in the amount of any payment to be made to it or for its account
pursuant to paragraph (A) or a claim for indemnification under paragraph (B),
then, without in any way limiting, reducing or otherwise qualifying the
obligations of the Obligors hereunder, such Bank shall promptly upon becoming
aware of the same notify the Agent thereof and shall, in consultation with
the Agent and the Borrower and to the extent that it can do so without
prejudice to its own position, take all reasonable steps as may be open to it
to mitigate or avoid the effects of such circumstances, including the change
of its Lending Office or the transfer of its rights and obligations hereunder
to another bank acceptable to the Borrower and willing to participate in the
Facility provided that such Bank shall be under no obligation to take any
such action if, in such Bank's BONA FIDE opinion, to do so may have any
adverse effect upon its business, operations or financial condition.

(E)    The provisions of Article 13 (I) shall apply MUTATIS MUTANDIS in
respect of or in relation to any payment made or to be made by any Obligor
pursuant to the provisions of paragraph (B).

17. THE GUARANTEE

(A)    The Guarantor irrevocably and unconditionally guarantees by way of an
independent guarantee ("GARANTIE AUF ERSTES ANFORDERN") to the Agent and each
Bank the due and punctual payment by the Borrower, under and in connection
with the terms of this Agreement, and

<PAGE>

covenants to pay or cause to be paid to the person entitled thereto in the
currency in which the same is for the time being due and payable under this
Agreement (and which remain for the time being unpaid) of (i) any amount up
to USD 45,000,000 or its equivalent borrowed under Tranche A, and (ii) any
the sum of principal, interest and all other monies which are now or may at
any time hereafter be due and payable by the Borrower under or pursuant to
this Agreement with respect to the said amount.

(B)    The Guarantor shall effect payment hereunder promptly upon demand of
the Agent (or any Bank through the Agent) and confirmation that the amount
claimed from the Guarantor is equal to the Guaranteed Amount which the
Borrower has not paid when due.

(C)    The obligations of the Guarantor hereunder (i) shall be separate and
independent from the obligations of the Borrower, (ii) shall exist
irrespective of the legality, validity, binding effect and enforceability of
any obligation of the Borrower under this Agreement, (iii) shall not be
affected by any event, condition or circumstance of whatever nature, whether
factual or legal, save the full, definite and irrevocable satisfaction of any
and all payment obligations expressed to be assumed under this Agreement and
(iv) shall be deemed "Senior Debt" under the indenture governing the Wavetek
Bond.

(D)    The Agent and each Bank may at any time without thereby discharging,
impairing or otherwise affecting the obligations of the Guarantor hereunder
(i) give or agree to give any time or other indulgence to the Borrower in
respect of its obligations under this Agreement or any of them, (ii) (with
the consent of the Guarantor) offer or agree to or enter into any agreement
for any variation of this Agreement, or (iii) prove or abstain from proving,
in respect of the obligations of the Borrower under this Agreement, in a
bankruptcy, winding-up, liquidation or reorganization of the Borrower.

(E)    The obligations of the Guarantor hereunder are (and are intended to
be) a continuing and independent security to the Agent and each Bank, as the
case may be, for the due and punctual payment by the Borrower, under and in
accordance with the terms of this Agreement, of the Guaranteed Amount and
interest thereon and all other monies related thereto which are now or may at
any time hereafter be due and payable by the Borrower under or pursuant to
this Agreement and accordingly the said obligations (i) shall be in addition
to and not in substitution for or derogation from any other encumbrance,
guarantee or other security now or at any time hereafter held by or on behalf
of the Agent or such Bank in respect of the obligations of the Borrower under
this Agreement or any of them, (ii) shall not be or be construed to be
satisfied by any discharge of or payment of or on account of the obligations
of the Borrower under this Agreement or any of them which has not resulted in
a final and irrevocable settlement of the

<PAGE>

respective obligation, and (iii) shall at all times extend to cover the
balance of principal, interest and all other monies which are now or may at
any time hereafter be due and payable by the Borrower under or pursuant to
this Agreement.

(F)    Neither the Agent nor any Bank shall be obliged before asserting or
enforcing the obligations of the Guarantor hereunder (i) to take action or
obtain judgement against the Borrower in any court, (ii) to make or file any
claim or proof in any bankruptcy, winding-up, liquidation or reorganization
of the Borrower or (iii) to enforce or seek to enforce any other encumbrance,
guarantee or other security now or at any time hereafter held by or on behalf
of the Agent or such Bank in respect of the obligations of the Borrower under
this Agreement or any of them.

(G)    Where any payment has been made by the Guarantor to the Agent or any
Bank hereunder the Guarantor shall not take the benefit of subrogation (if
any) of any rights of any such person or any encumbrance, guarantee or other
security now or any time hereafter held by or on behalf of such person in
respect of the obligations of the Borrower under this Agreement or any of
them until and unless all obligations of the Borrower under this Agreement
have been discharged in full.

(H)    The guarantee given under this Agreement may be enforced against the
Guarantor by each Bank or by the Agent as agent for the Banks in any
proceedings, including enforcement proceedings.

(I)    The Agent and the Banks confirm that it is the intention of all
parties that the guarantee by the Guarantor not constitute a fraudulent
transfer or conveyance for purposes of the Bankruptcy Law, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
federal or state law. To effectuate the foregoing intention, the Banks and
the Guarantor hereby irrevocably agree that the obligations of the Guarantor
under this Article 17 shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such
Guarantor, result in the obligations of the Guarantor under the guarantee not
constituting a fraudulent transfer or conveyance.

18. REPRESENTATIONS AND WARRANTIES

(P)    there shall occur any of the following events which have a Material
       Adverse Effect:

(1)    the happening of a Reportable Event (as defined in Section 4043 of
       ERISA) with respect to any Plan;

(2)    the disqualification or involuntary termination of a Plan for any reason;

(3)    the voluntary termination of any plan while such plan has a funding
       deficiency (as determined under Section 412 of the Code);

(4)    the institution of any proceedings by the PBGC to terminate any such
       Plan or to appoint a trustee to administer any such Plan;

(5)    the failure of any of the Obligors to notify the Agent and the Banks
       promptly upon the receipt by such Obligor or any of its affiliates of
       any notice of the institution of any proceeding or other actions which
       may result in the termination of any such Plan

<PAGE>

then, and in any such event and at any time thereafter, if any such event
shall be continuing, the Agent may (and, if so instructed by the Majority
Banks, shall) take either or both of the following actions:

(1)    by notice to the Borrower declare the Loan immediately due and payable
       whereupon the same shall become so payable together with interest
       accrued thereon and all other amounts payable hereunder; or

(2)    by notice to the Borrower declare that the Revolving Facility
       Commitments of all the Banks shall be cancelled, whereupon the same

(B)    The Borrower shall pay to the Agent and the Arrangers the fees

against such Obligor under the Facility Documents or in connection with any
amendments, waivers or consents required during the term of this Agreement in
respect thereof.

<PAGE>

(B)    Each Obligor shall pay any and all stamp, registration and similar
taxes and charges of whatsoever nature (other than any tax referred to in
Article 13 (A)) which may be payable or determined to be payable on, or in
connection with, the execution or performance of the Facility Documents, by
such Obligor, the enforcement of the Facility Documents against such Obligor

Obligor and shall, from time to time on demand of the Agent, indemnify the

24. THE AGENT, THE ARRANGERS AND THE BANKS

(A)    Each Bank hereby appoints the Agent to act as its agent in connection
herewith and authorizes the Agent to exercise such rights, powers and
discretions as are specifically delegated to the Agent by the terms hereof
together with all such rights, powers and discretions as are reasonably
incidental thereto.

(B)    When acting in connection with this Agreement, the Agent may:

(1)    assume that no Event of Early Repayment and no event which with the
       giving of notice, lapse of time or fulfilment of any other condition
       would or might constitute an Event of Early Repayment has occurred and
       that none of the Obligors is in breach of or default under its
       respective obligations hereunder unless it has received express notice
       thereof from any party hereto or (in the case of a payment default
       hereunder) gained actual knowledge thereof;

(2)    assume that each Bank's Lending Office is that identified with its
       signature below until it has received from such Bank notice
       designating any other office of such Bank as its Lending Office and
       act upon any such notice until the same is superseded by a further
       such notice;

(3)    engage and pay for the advice or services of any experienced lawyers,
       accountants, surveyors or other experts whose advice or services may
       to it seem necessary, expedient or desirable and rely upon any advice
       so obtained;

(4)    rely as to any matters of fact which might reasonably be expected to
       be within the knowledge of any of the Obligors upon a certificate
       signed by or on behalf of such Obligor;

<PAGE>

(5)    rely upon any communication or document believed by it to be genuine;

(6)    refrain from exercising any right, power or discretion vested in it
       hereunder unless and until instructed by the Majority Banks as to the
       manner in which such right, power or discretion should be exercised;

(7)    refrain from acting in accordance with any instructions of the
       Majority Banks to begin any legal action or proceeding arising out of
       or in connection with this Agreement until it shall have received such
       security as it may require (whether by way of payment in advance or
       otherwise) for all costs, claims, expenses (including legal fees) and
       liabilities together with any value added tax or similar tax  thereon
       which it will or may expend or incur in complying with such
       instructions;

(8)    if it is unable to obtain instructions or communicate with a Bank
       after making reasonable attempts to do so, either refrain from acting
       as Agent on behalf of such Bank or take such action on behalf of such
       Bank as it in its absolute discretion deems appropriate and shall not
       be liable to such Bank as a result of any such action or inaction
       (save in the case of gross negligence or wilful misconduct); and

(9)    refrain from acting in accordance with any instructions of the
       Majority Banks if in its reasonable opinion they are contrary to
       applicable law.

(C)    The Agent shall:

(1)    promptly inform each Bank of the contents of any notice or document
       received by it from any of the Obligors hereunder or from any Bank
       where such notice or document concerns the rights, interest and/or
       obligations of all the Banks hereunder;

(2)    promptly notify each Bank of the occurrence of any Event of Early
       Repayment or any event which with the giving of notice or lapse of
       time or fulfilment of any other condition would or might constitute an
       Event of Early Repayment or any failure of any of the Obligors duly to
       perform its respective obligations under this Agreement of which the
       Agent has received express notice from any party hereto or (in the
       case of a payment default hereunder) gained actual knowledge;

(3)    subject as herein provided, act in accordance with any instructions
       given to it by the Majority Banks and, if so instructed by the
       Majority Banks, refrain from exercising a right, power or discretion
       vested in it hereunder.

<PAGE>

(D)    The Agent shall not:

(1)    be bound to enquire as to the occurrence or otherwise of any Event of
       Early Repayment (unless a payment default has occurred hereunder or
       the Agent has been informed in writing by a Bank describing in
       reasonable detail an occurrence of an event which is expressly stated
       to be an Event of Early Repayment) or any event which with the giving
       of notice or lapse of time or fulfilment of any other condition would
       or might constitute an Event of Early Repayment or as to any failure
       of any of the Obligors duly to perform its respective obligations
       hereunder;

(2)    be bound to account to any Bank for any sum or the profit element of
       any sum received by it for its own account;

(3)    initiate any legal proceedings on behalf of any Bank unless
       specifically authorized by such Bank to do so, but the failure of any
       Bank to give such authorization shall not limit the right of the Agent
       to do so on behalf of any other Bank;

(4)    be bound to disclose to any other person any information relating to
       any of the Obligors received by the Agent if such disclosure would or
       might in the opinion of the Agent constitute a breach of any law or
       regulation or be otherwise actionable by any person; or

(5)    be under any fiduciary duty towards any Bank or under any obligations
       other than those for which express provision is made herein.

(E)    Each Bank shall indemnify the Agent in the proportion its share of the
Loan bears to the amount of the Loan or, as the case may be, the amount of
its Commitment bears to the Total Commitments at the time any such
instructions are given, against any and all costs, claims, expenses
(including legal fees) and liabilities which the Agent may incur in complying
with any instructions received by it from the Banks insofar as such expenses
are not punctually reimbursed by the Obligors pursuant to the terms hereof
except routine administrative costs and expenses of the Agent or to the
extent that these costs, claims, expenses and liabilities are sustained or
incurred as a result of the gross negligence or wilful misconduct of the
Agent or any of its personnel or agents.

(F)    Each Bank agrees that neither the Agent nor the Arrangers shall be
responsible for the accuracy and completeness of any representations made
(whether orally or otherwise) herein or in connection herewith, for the
validity, effectiveness, adequacy or enforceability of this

<PAGE>

Agreement or for the creditworthiness of any of the Obligors, any other
member of the Group or the Group as a whole. Neither the Agent nor the
Arrangers nor any of their directors, officers or employees shall be under
any liability for or in respect of any action taken or omitted by any of them
in relation to this Agreement save for its or his gross negligence or wilful
misconduct.

(G)    The Arrangers and the Agent may accept deposits from, lend money to
and generally engage in any kind of banking or other business with the
Borrower.

(H)    It is understood and agreed by each Bank that it has been, and will
continue to be, solely responsible for making its own independent appraisal
of and investigations into the financial condition, creditworthiness and
affairs of each of the Obligors, each other member of the Group and the Group
as a whole and accordingly each Bank confirms to the Agent and the Arranges
that it has not relied, and will not hereafter rely, on the Agent or the
Arrangers:

(1)    to check or enquire on its behalf into the adequacy, accuracy or
       completeness of any information provided by any of the Obligors in
       connection with this Agreement or the transactions herein contemplated
       whether or not such information has been or is hereafter circulated to
       such Bank by the Agent or any of the Arrangers; or

(2)    to assess or keep under review on its behalf the financial condition,
       creditworthiness or affairs of any of the Obligors, any other member
       of the Group or the Group as a whole.

(I)    In acting as agent for the Banks under the Facility Documents the
Agent shall be regarded as acting through its agency division which shall be
treated as a separate entity from any other of its divisions or departments
and, notwithstanding the foregoing provisions of this Article 24, any
information received by some other division or department of the Agent may be
treated as confidential and shall not be regarded as having been given to the
Agent's agency division, unless the Agent had actual knowledge thereof or as
a matter of good faith (TREU UND GLAUBEN) the Banks could expect that such
information would have been passed on to them. Notwithstanding anything to
the contrary expressed or implied herein and without prejudice to the
provisions of this paragraph (I), the Agent shall not as between itself and
the Banks be bound to disclose to any Bank or any other person any
information which is supplied by the Obligors to the Agent other than in ist
capacity as agent hereunder.

(J)    The Agent may (and if so instructed by the Majority Banks, shall) for
any reason at any time retire upon not less than forty-five days' written
notice to each of the parties hereto of its intention to do so and, if any
such notice is given by the Agent, the Agent shall upon the appointment of a
successor agent as hereinafter provided for cease to be under any further

<PAGE>

obligation as Agent hereunder. Following delivery of any such notice, the
Majority Banks may appoint a successor agent and if, before the expiry of
such notice, such successor agent notifies the parties hereto that it accepts
such appointment, (i) each reference herein to "the Agent" shall thereafter
be construed as a reference to the successor agent and (ii) the successor
agent and the parties hereto other than the retiring Agent shall thereafter
have such rights and obligations INTER SE as they would have had if the
successor agent had been a party hereto as the Agent. If no successor agent
appointed by the Majority Banks notifies the parties hereto, prior to the
expiry of the Agent's notice of its intention to retire giving rise to the
need to appoint the same, of its acceptance of such appointment, the Agent in
consultation with the Borrower may appoint any experienced and reputable bank
to be the successor agent and, if it does and such successor agent notifies
the parties hereto that it accepts such appointment, (a) each reference
herein to "the Agent" shall thereafter be construed as a reference to the
successor agent so appointed and (b) the successor agent so appointed and the
parties hereto other than the retiring Agent shall thereafter have such
rights and obligations INTER SE as they would have if the successor agent so
appointed had been named herein as the Agent.

(K)    If any Reference Bank shall be prepaid under this Agreement or shall
cease to have any Commitment or after the first drawdown cease to have any
principal or interest owing to it hereunder, the Agent may in consultation
with the Borrower and the Majority Banks appoint a substitute Reference Bank.

(L)    The Agent shall be released from the restrictions set out in paragraph
181 of the German Civil Code (BURGERLICHES GESETZBUCH).

25. CERTIFICATES

A Bank which makes a demand in respect of (i) the amount being necessary to
compensate such Bank under Article 7 (D) or (ii) its cost of funding as
referred to in Article 8 (C) or (iii) the amount necessary to compensate it
for any damages or losses referred to in Article 14 (D) or (iv) the amount
for the time being required to compensate it for any cost as mentioned in
Article 16 (A) or (v) to indemnify it against any such claim or liability as
is mentioned in Article 16 (B) shall deliver a certificate which sets out in
reasonable detail the calculation of such amount and the factual basis for
such calculation. Any such certificate shall constitute PRIMA FACIE evidence
for the purposes hereof save for manifest error.

<PAGE>

26. NO WAIVER

No failure to exercise and no delay in exercising on the part of the Agent or
any Bank any right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or
privilege preclude any other or future exercise thereof, or the exercise of
any other right, power or privilege. The rights and remedies herein provided
are cumulative to any rights or remedies provided by law.

27. PARTIAL INVALIDITY

If at any time any provision of this Agreement is or becomes illegal, invalid
or unenforceable in any respect under the law of any jurisdiction, neither
the legality, validity or enforceability of the remaining provisions hereof
nor the legality, validity or enforceability of such provision under the law
of any other jurisdiction shall be affected or impaired thereby. Any
provision which is or becomes illegal, invalid or unenforceable shall be
deemed to be substituted by a provision which comes as close as possible to
purpose and spirit of the illegal, invalid or unenforceable provision.

28. AMENDMENTS AND WAIVERS

If authorised by the Majority Banks, the Agent may (except where any other
authority is required for the same by the provisions of this Agreement) grant
waivers or vary the terms of the provisions of this Agreement. Any such
waiver or variation so authorised and effected by the Agent shall be binding
on all the Banks and the Agent shall be under no liability whatsoever in
respect of any such waiver or variation, provided always that, except with
the prior consent of all the Banks, nothing in this Article 28 shall
authorise:

(1)    any reduction in any rate at which interest or any fee is payable
       under this Agreement;

(2)    any extension of the date for, or alteration in the amount or currency
       of, any payment of principal, interest, fees or any other amount
       payable under this Agreement or any extension of the Final Maturity
       Date;

(3)    any increase in or decrease of (i) any Bank's Total Commitment and
       (ii) the commitment of Deutsche Bank AG, Reutlingen Branch as set out
       in the Sixth Schedule;

(4)    any variation of a term of this Agreement which expressly provides for
       the consent of all the Banks; and

<PAGE>

(5)    any variation of Article 1 Definition of "Majority Banks" and
       "EURIBOR", Article 2 (The Facilities), Article 15 (Set-off and
       Redistribution of Payments), Article 17 (Guarantee), Article 20
       (Financial Covenants), Article 29 (Change of Lending Office and
       Assignments), or this Article 28;

provided that any such waiver or variation relating to Article 24 or
otherwise affecting the rights and/or obligations of the Agent shall also
require the consent of the Agent and provided further that any such variation
affecting the rights and/or obligations of an Obligor shall also require the
consent of such Obligor.

29. CHANGE OF LENDING OFFICE AND ASSIGNMENTS

(A)    None of the Obligors may assign or transfer all or any of its rights,
benefits and obligations hereunder without the prior written consent of all
the Banks.

(B)    Any Bank may at any time (i) change its Lending Office by notifying
such other office to the Agent or (ii) assign and transfer with the prior
consent of the Borrower (such consent not to be unreasonably withheld), any
of its rights or obligations under this Agreement to another bank or
financial institution provided (i) such assignment shall be made in minimum
amounts of DM 10 million (or following its introduction Euro 5 million) and
(ii) that no consent of the Borrower shall be required (a) if the transferee
is another Bank or an affiliate of the transferor or (b) following the
occurrence of an Event of Early Repayment.

(C)    A Bank may neither assign or transfer any of its rights arising out of
an Advance separately from any corresponding share of its Revolving Credit
Facility Commitment under this Agreement (save for cases where such
assignment is made in order to avoid or mitigate any withholding tax on
account of which no payment would have to be made to such Bank pursuant to
Article 13 (A) (1)) nor assign or transfer any part of its Revolving Credit
Facility Commitment under this Agreement separately from its rights arising
out of its corresponding participation in any existing Advance(s).

A transfer and assignment may be effected only by the delivery to the Agent
of a duly completed and duly executed Transfer Certificate (subject to the
minimum transfer amount set out therein) in which event, on the transfer
date(s) specified in such Transfer Certificate:

(i)    to the extent that in such Transfer Certificate the Bank party thereto
       seeks to transfer its rights, benefits and obligations hereunder, each
       of the Obligors and such Bank shall be

<PAGE>

       released from further obligations towards one another hereunder and
       their respective rights against one another shall be cancelled (such
       rights, benefits and obligations being referred to in this paragraph (C)
       as "DISCHARGED RIGHTS AND OBLIGATIONS");

(ii)   each of the Obligors and the transferee party thereto shall assume
       obligations towards one another and/or acquire rights against one
       another which differ from such discharged rights and obligations only
       insofar as such Obligor and such transferee have assumed and/or
       acquired the same in place of such Obligor and such Bank; and

(iii)  the Agent, the Arrangers, such transferee and the other Banks shall
       acquire the same rights and benefits and assume the same obligations
       between themselves as they would have acquired and assumed had such
       transferee been an original party hereto as a Bank with the rights,
       benefits and/or obligations acquired or assumed by it as a result of
       such transfer

The Agent shall give notice of any such transfer and assignment to the
Borrower.

(D)    If as a direct or, on the basis of information which is in the public
domain, foreseeable result of any change of Lending Office or any assignment
and transfer as referred to in paragraph (B) at the time of such change of
Lending Office or such assignment and transfer or immediately thereafter any
Obligor would be liable to make a payment pursuant to Article 13 (A) (1) or
Article 16 (A) or to pay an indemnification pursuant to Article 16 (B), then
the obligation to make such payment or to pay such indemnification shall not
arise, unless such change of Lending Office or transfer and assignment was
made pursuant to Article 16 (D).

(E)    Each transferee shall pay to the Agent for its own account on the
transfer date(s) (as set out in the Transfer Certificate) a registration fee
of DM 2,000 (EURO 1,000 following the commencement date), payable under
pre-advice.

(F)    A Bank may disclose information relating to the Obligors and any other
member of the Group or this Agreement and the Facility to its auditors,
legal, tax and other professional advisers upon their request but in each
case only where the same are advising on matters relating to the Facility or
performing their auditing functions; or to any actual or potential assignee
or transferee or any person with whom it may in accordance with paragraph (A)
enter into a transfer, assignment or other agreement in relation to this
Agreement.

<PAGE>

(G)    Each Bank (and Deutsche Bank AG, Reutlingen Branch) (the "ASSIGNOR")
may assign and transfer its commitment under the Ancillary Facility to which
it is party provided that the assignee accepts any relevant obligation
assumed by the Assignor hereunder.

30. LANGUAGE

correct by a duly authorized officer of the person making or delivering the
same), provided that the documents delivered pursuant to the Second Schedule
and (with the consent of the Agent) any other documents originating from a
public register may be delivered in their respective original language.

31. APPOINTMENT OF WGMH AS REPRESENTATIVE

declaration or notice or negotiation to be made hereunder or in connection

another pursuant to this Agreement shall (unless that other person has by
fifteen days' written notice to the Agent specified another address) be made

signature below (or, in the case of a transferee, at the end of the Transfer
Certificate to which it is a party as transferee) and shall be deemed to have

by letter) when left at that address or (in the case of any communication by
telefax) when actually received, provided that

<PAGE>

any communication or document to be made or delivered to the Agent shall be
effective only when received by the Agent and then only if the same is
expressly marked for the attention of the department identified with the
Agent's signature below (or such other department as the Agent shall from
time to time specify for this purpose) and provided further that if the time
of receipt of any communication or document is not a business day in the
country of the addressee or is not within working hours, such communication
or document shall be deemed to have been received at the opening of business
on the next Business Day.
