         SECTION 1.02 Classification of Loans and Borrowings. For purposes of
this Agreement, Loans may be classified and referred to by Class (e.g., a
"Revolving Loan") or by Type (e.g., a "Eurocurrency Loan") or by Class and Type

referred to by Class (e.g., a "Revolving Borrowing") or by Type (e.g., a
"Eurocurrency Borrowing") or by Class and Type (e.g., a "Eurocurrency Revolving
Borrowing"). Eurocurrency Loans or Borrowings may be Alternative Currency Loans
or Borrowings or Dollar Loans or Borrowings.

         SECTION 1.03 Terms Generally. The definitions of terms herein shall
apply equally to the singular and plural forms of the terms defined. Whenever
the context may require, any pronoun shall include the corresponding masculine,
feminine and neuter forms. The words "include", "includes" and "including" shall
be deemed to be followed by the phrase "without limitation". The word "will"
shall be construed to have the same meaning and effect as the word "shall".
Unless the context requires otherwise (a) any definition of or reference to

                                       25
<PAGE>

any agreement, instrument or other document herein shall be construed as
referring to such agreement, instrument or other document as from time to time
amended, supplemented or otherwise modified (subject to any restrictions on such
amendments, supplements or modifications set forth herein), (b) any reference
herein to any Person shall be construed to include such Person's successors and
assigns, (c) the words "herein", "hereof" and "hereunder", and words of similar
import, shall be construed to refer to this Agreement in its entirety and not
to any particular provision hereof, (d) all references herein to Articles,
Sections, Exhibits and Schedules shall be construed to refer to Articles and
Sections of, and Exhibits and Schedules to, this Agreement and (e) the words
"asset" and "property" shall be construed to have the same meaning and effect
and to refer to any and all tangible and intangible assets and properties,
including cash, securities, accounts and contract rights.

         SECTION 1.04 Accounting Terms; GAAP. Except as otherwise expressly
provided herein, all terms of an accounting or financial nature shall be
construed in accordance with GAAP, as in effect from time to time; provided
that, if the Borrower notifies the Administrative Agent that the Borrower
requests an amendment to any provision hereof to eliminate the effect of any
change occurring after the date hereof in GAAP or in the application thereof on
the operation of such provision (or if the Administrative Agent notifies the
Borrower that the Required Lenders request an amendment to any provision hereof
for such purpose), regardless of whether any such notice is given before or
after such change in GAAP or in the application thereof, then such provision
shall be interpreted on the basis of GAAP as in effect and applied immediately
before such change shall have become effective until such notice shall have been
withdrawn or such provision amended in accordance herewith.

         SECTION 1.05 Exchange Rates. On each Calculation Date, the
Administrative Agent shall determine the Exchange Rate as of such Calculation
Date to be used for calculating relevant Dollar Equivalent and Alternative
Currency Equivalent amounts. The Exchange Rates so determined shall become
effective on such Calculation Date shall remain effective until the next
succeeding Calculation Date and shall for all purposes of this Agreement (other
than any provision expressly requiring the use of a current Ex change Rate) be
the Exchange Rates employed in converting any amounts between the applicable
currencies.

         SECTION 1.06 Redenomination of Sterling. (a) Each obligation of any
party to this Agreement to make a payment denominated in the national currency
unit of any member state of the European Union that adopts the Euro as its
lawful currency after the date hereof shall be redenominated into Euro at the
time of such adoption (in accordance with the applicable UK legislation and EC
Treaty). If, in relation to the currency of any such member state, the basis of
accrual of interest expressed in this Agreement in respect of that currency
shall be inconsistent with any convention or practice in the London Interbank
Market for the basis of accrual of interest in respect of the Euro, such
expressed basis shall be replaced by such convention or practice with that if
any Borrowing in the currency of such member state is outstanding immediately
prior to such date, such replacement shall take effect, with respect to such
Borrowing, at the end of the then current Interest Period.

         (b) Each provision of this Agreement shall be subject to such
reasonable changes of construction as the Administrative Agent may from time to
time specify to be appropriate to reflect the adoption of the Euro by any member
state of the European Union and any relevant market conventions or practices
relating to the Euro.


                                  ARTICLE II
                                  The Credits

         SECTION 2.01 Commitments. Subject to the terms and conditions set forth
herein and, in particular during the Certain Funds Period, the penultimate
paragraph of Article VII, each Lender agrees to make Revolving Loans to the
Borrower in Dollars or an Alternative Currency from time to time during the
Availability Period in an aggregate principal amount that will not result in (a)
such Lender's Revolving Credit Exposure exceeding such Lender's Commitment or
(b) the sum of the total Revolving Credit Exposures plus the aggregate principal
amount of outstanding Competitive Loans exceeding the total Commitments or (c)
in the case only of Loans constituting Other Borrowings during the Certain Funds
Period, the sum of the total Revolving Credit Exposures plus the aggregate
principal amount of outstanding Competitive Loans plus the Certain Funds
Committed Amount exceeding the total Commitments. Within the foregoing limits
and subject to the terms and conditions set forth herein, the Borrower may
borrow, prepay and reborrow Revolving Loans.

         SECTION 2.02 Loans and Borrowings.

         (a) Each Revolving Loan shall be made as part of a Borrowing consisting
of Revolving Loans made by the Lenders ratably in accordance with their
respective Commitments. Each Competitive Loan shall be made in accordance with
the procedures set forth in Section 2.04. The failure of any Lender to make any
Loan required to be made by it shall not relieve any other Lender of its
obligations hereunder; provided that the Commitments and Competitive Bids of the
Lenders are several and no Lender shall be responsible for any other Lender's
failure to make Loans as required.

         (b) Subject to Section 2.14, (i) each Revolving Borrowing shall be
comprised entirely of ABR Loans or Eurocurrency Loans as the Borrower may
request in accordance herewith, and (ii) each Competitive Borrowing shall be
comprised entirely of Eurocurrency Loans or Fixed Rate Loans as the Borrower may
request in accordance herewith. Each Lender at its option may make any
Eurocurrency Loan by causing any domestic or foreign branch or Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not
affect the obligation of the Borrower to repay such Loan in accordance with the
terms of this Agreement.

                                       27

         (c) At the commencement of each Interest Period for any Eurocurrency
Revolving Borrowing, such Borrowing shall be in an aggregate amount that is an
integral multiple of $1,000,000 (or the Alternative Currency Equivalent thereof)
and not less than $5,000,000 (or the Alternative Currency Equivalent thereof).
Each Competitive Borrowing shall be in an aggregate amount that is an integral
multiple of $1,000,000 (or in the case of Eurocurrency Competitive Borrowings
denominated in an Alternative Currency, the Alternative Currency Equivalent
thereof) and not less than $5,000,000 (or in the case of Eurocurrency
Competitive Borrowings denominated in an Alternative Currency, the Alternative
Currency Equivalent thereof). Borrowings of more than one Type and Class may be
outstanding at the same time; provided that there shall not at any time be more
than a total of ten Eurocurrency Revolving Borrowings outstanding.

         (d) Notwithstanding any other provision of this Agreement, the Borrower
shall not be entitled to request, or to elect to convert or continue, any
Borrowing if the Interest Period requested with respect thereto would end after
the Maturity Date.

         SECTION 2.03 Requests for Revolving Borrowings. To request a Revolving
Borrowing, the Borrower shall notify the Administrative Agent of such request by

not later than 11:00 a.m., New York City time, and in the case of a Eurocurrency
Borrowing denominated in an Alternative Currency, not later than 9:30 a.m., New
York City time, in each case three Business Days before the date of the proposed
Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New

such telephonic Borrowing Request shall be irrevocable and shall be confirmed
promptly by hand delivery or telecopy to the Administrative Agent of a written
Borrowing Request in a form approved by the Administrative Agent and signed by
the Borrower. Each such telephonic and written Borrowing Request shall specify
the following information in compliance with Section 2.02:

         (i)     the aggregate amount of the requested Borrowing;

         (ii)    the date of such Borrowing, which shall be a Business Day;

         (iii)   whether such Borrowing is to be an ABR Borrowing or a
      Eurocurrency Borrowing;

         (iv)    in the case of a Eurocurrency Borrowing whether such Borrowing
      is to be a Dollar Borrowing or an Alternative Currency Borrowing, the
      initial Interest Period to be applicable thereto, which shall be a period
      contemplated by the definition of the term "Interest Period"; and

         (v)     the location and number of the Borrower's account to which
      funds are to be disbursed, which shall comply with the requirements of
      Section 2.07.

<PAGE>

         If no election as to the Type of Revolving Borrowing is specified, then
the requested Revolving Borrowing shall be an ABR Borrowing. If no currency is
specified with respect to any requested Eurocurrency Revolving Borrowing, then
the Borrowing shall be a Dollar Borrowing. If no Interest Period is specified
with respect to any requested Eurocurrency Revolving Borrowing, then the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. Promptly following receipt of a Borrowing Request in accordance with
this Section, the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Loan to be made as part of the
requested Borrowing.

         SECTION 2.04 Competitive Bid Procedure.

         (a) Subject to the terms and conditions set forth herein, from time to
time during the Availability Period the Borrower may request Competitive Bids
and may (but shall not have any obligation to) accept Competitive Bids and
borrow Competitive Loans; provided that (i) the sum of the total Revolving
Credit Exposures plus the aggregate principal amount of outstanding Competitive
Loans at any time shall not exceed the total Commitments and (ii) during the
Certain Funds Period, the sum of the Revolving Credit Exposures plus the
aggregate principal amount of outstanding Competitive Loans plus the Certain
Funds Committed Amount shall not exceed the total Commitments. To request
Competitive Bids, the Borrower shall notify the Administrative Agent of such
request by telephone, in the case of a Eurocurrency Borrowing denominated in
Dollars, not later than 11:00 a.m., New York City time, or in the case of a
Eurocurrency Borrowing denominated in an Alternative Currency, not later than

than 10:00 a.m., New York City time, one Business Day before the date of the
proposed Borrowing; provided that the Borrower may submit up to (but not more
than) three Competitive Bid Requests on the same day, but a Competitive Bid
Request shall not be made within five Business Days after the date of any
previous Competitive Bid Request, unless any and all such previous Competitive
Bid Requests shall have been withdrawn or all Competitive Bids received in
response thereto rejected. Each such telephonic Competitive Bid Request shall be
confirmed promptly by hand delivery or telecopy to the Administrative Agent of a
written Competitive Bid Request in a form approved by the Administrative Agent
and signed by the Borrower. Each such telephonic and written Competitive Bid
Request shall specify the following information in compliance with Section 2.02:

         (i)     the aggregate amount of the requested Borrowing;

         (ii)    the date of such Borrowing, which shall be a Business Day;

         (iii)   whether such Borrowing is to be a Eurocurrency Borrowing or a
      Fixed Rate Borrowing;

                                       29
<PAGE>

         (iv) the Interest Period to be applicable to such Borrowing, which
      shall be a period contemplated by the definition of the term "Interest
      Period"; and

         (v)  the location and number of the Borrower's account to which funds
      are to be disbursed, which shall comply with the requirements of Section
      2.07.

Promptly following receipt of a Competitive Bid Request in accordance with this
Section, the Administrative Agent shall notify the Lenders of the details
thereof by telecopy, inviting the Lenders to submit Competitive Bids.

         (b) Each Lender may (but shall not have any obligation to) make one or
more Competitive Bids to the Borrower in response to a Competitive Bid Request.
Each Competitive Bid by a Lender must be in a form approved by the
Administrative Agent and must be received by the Administrative Agent by
telecopy, in the case of a Eurocurrency Competitive Borrowing, not later than
9:30 a.m., New York City time, three Business Days before the proposed date of
such Competitive Borrowing, and in the case of a Fixed Rate Borrowing, not later
than 9:30 a.m., New York City time, on the proposed date of such Competitive
Borrowing. Competitive Bids that do not conform substantially to the form
approved by the Administrative Agent may be rejected by the Administrative
Agent, and the Administrative Agent shall notify the applicable Lender as
promptly as practicable. Each Competitive Bid shall specify (i) the principal
amount (which shall be a minimum of $5,000,000 (or, in the case of a
Eurocurrency Competitive Borrowing denominated in an Alternative Currency, the
Alternative Currency Equivalent thereof) and an integral multiple of $1,000,000
(or, in the case of a Eurocurrency Competitive Borrowing denominated in an
Alternative Currency, the Alternative Currency Equivalent thereof) and which may
equal the entire principal amount of the Competitive Borrowing requested by the
Borrower) of the Competitive Loan or Loans that the Lender is willing to make,
(ii) the Competitive Bid Rate or Rates at which the Lender is prepared to make
such Loan or Loans (expressed as a percentage rate per annum in the form of a
decimal to no more than four decimal places) and (iii) the Interest Period
applicable to each such Loan and the last day thereof.

         (c) The Administrative Agent shall promptly notify the Borrower by
telecopy of the Competitive Bid Rate and the principal amount specified in each
Competitive Bid and the identity of the Lender that shall have made such
Competitive Bid.

         (d) Subject only to the provisions of this paragraph, the Borrower may
accept or reject any Competitive Bid. The Borrower shall notify the
Administrative Agent by telephone, confirmed by telecopy in a form approved by
the Administrative Agent, whether and to what extent it has decided to accept or
reject each Competitive Bid, in the case of a Eurocurrency Competitive
Borrowing, not later than 10:30 a.m., New York City time, three Business Days
before the date of the proposed Competitive Borrowing, and in the case of a
Fixed Rate Borrowing, not later than 10:30 a.m., New York City time, on the
proposed date

                                       30
<PAGE>

of the Competitive Borrowing; provided that (i) the failure of the Borrower to
give such notice shall be deemed to be a rejection of each Competitive Bid, (ii)
the Borrower shall not accept a Competitive Bid made at a particular Competitive
Bid Rate if the Borrower rejects a Competitive Bid made at a lower Competitive
Bid Rate, (iii) the aggregate amount of the Competitive Bids accepted by the
Borrower shall not exceed the aggregate amount of the requested Competitive
Borrowing specified in the related Competitive Bid Request, (iv) to the extent
necessary to comply with clause (iii) above, the Borrower may accept Competitive
Bids at the same Competitive Bid Rate in part, which acceptance, in the case of
multiple Competitive Bids at such Competitive Bid Rate, shall be made pro rata
in accordance with the amount of each such Competitive Bid, and (v) except
pursuant to clause (iv) above, no Competitive Bid shall be accepted for a
Competitive Loan unless such Competitive Loan is in a minimum principal amount
of $5,000,000 (or, in the case of a Eurocurrency Competitive Borrowing
denominated in an Alternative Currency, the Alternative Currency Equivalent
thereof) and an integral multiple of $1,000,000 (or, in the case of a
Eurocurrency Competitive Borrowing denominated in an Alternative Currency, the
Alternative Currency Equivalent thereof); provided further that if a Competitive
Loan must be in an amount less than $5,000,000 (or, in the case of a
Eurocurrency Competitive Borrowing denominated in an Alternative Currency, the
Alternative Currency Equivalent thereof) because of the provisions of clause
(iv) above, such Competitive Loan may be for a minimum of $1,000,000 (or, in the
case of a Eurocurrency Competitive Borrowing denominated in an Alternative
Currency, the Alternative Currency Equivalent thereof) or any integral multiple
thereof, and in calculating the pro rata allocation of acceptances of portions
of multiple Competitive Bids at a particular Competitive Bid Rate pursuant to
clause (iv) the amounts shall be rounded to integral multiples of $1,000,000
(or, in the case of a Eurocurrency Competitive Borrowing denominated in an
Alternative Currency, the Alternative Currency Equivalent thereof) in a manner
determined by the Borrower. A notice given by the Borrower pursuant to this
paragraph shall be irrevocable.

         (e) The Administrative Agent shall promptly notify each bidding Lender
by telecopy whether or not its Competitive Bid has been accepted (and, if so,
the amount and Competitive Bid Rate so accepted), and each successful bidder
will thereupon become bound, subject to the terms and conditions hereof, to make
the Competitive Loan in respect of which its Competitive Bid has been accepted.

         (f) If the Administrative Agent shall elect to submit a Competitive Bid
in its capacity as a Lender, it shall submit such Competitive Bid directly to
the Borrower at least one quarter of an hour earlier than the time by which the
other Lenders are required to submit their Competitive Bids to the
Administrative Agent pursuant to paragraph (b) of this Section.

         SECTION 2.05  [not used].

         SECTION 2.06  [not used].

         SECTION 2.07  Funding of Borrowings.

         (a) Each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds by 12:00
noon, New York City time to the account of the Administrative Agent most
recently designated by it for such purpose by notice to the Lenders. The
Administrative Agent will make such Loans available to the Borrower by promptly
crediting the amounts so received, in like funds, to an account of the Borrower
or, in respect of Offer Borrowings, to the extent so directed by the Borrower in
writing in the applicable Borrowing Request or Competitive Bid Request, of
Newco, in each case maintained (unless otherwise approved by the Administrative
Agent) with the Administrative Agent and designated by the Borrower in the
applicable Borrowing Request or Competitive Bid Request.

         (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation or (ii) in the case of the Borrower,
the interest rate applicable to ABR Loans. If such Lender pays such amount to
the Administrative Agent, then such amount shall constitute such Lender's Loan
included in such Borrowing.

         SECTION 2.08  Interest Elections.

         (a) Each Revolving Borrowing initially shall be of the Type specified
in the applicable Borrowing Request and, in the case of a Eurocurrency Revolving
Borrowing, shall have an initial Interest Period as specified in such Borrowing
Request. Thereafter, the Borrower may elect to convert such Borrowing to a
different Type or to continue such Borrowing and, in the case of a Eurocurrency
Revolving Borrowing, may elect Interest Periods therefor, all as provided in
this Section. The Borrower may elect different options with respect to different
portions of the affected Borrowing, in which case each such portion shall be
allocated ratably among the Lenders holding the Loans comprising such Borrowing,

                                       32
<PAGE>

and the Loans comprising each such portion shall be considered a separate
Borrowing. This Section shall not apply to Competitive Borrowings which may not
be converted or continued.

         (b) To make an election pursuant to this Section, the Borrower shall
notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Revolving Borrowing of the Type resulting from such election to be
made on the effective date of such election. Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election
Request in a form approved by the Administrative Agent and signed by the
Borrower.

         (c) Each telephonic and written Interest Election Request shall specify
the following information in compliance with Section 2.02:

         (i) the Borrowing to which such Interest Election Request applies and,
      if different options are being elected with respect to different portions
      thereof, the portions thereof to be allocated to each resulting Borrowing
      (in which case the information to be specified pursuant to clauses (iii)
      and (iv) below shall be specified for each resulting Borrowing);

         (ii) the effective date of the election made pursuant to such Interest
      Election Request, which shall be a Business Day;

         (iii)   whether the resulting Borrowing is to be an ABR Borrowing or a
      Eurocurrency Borrowing; and

         (iv) if the resulting Borrowing is a Eurocurrency Borrowing, the
      Interest Period to be applicable thereto after giving effect to such
      election, which shall be a period contemplated by the definition of the
      term "Interest Period".

If any such Interest Election Request requests a Eurocurrency Borrowing but does
not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

         (d) Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

         (e) If the Borrower fails to deliver a timely Interest Election Request
with respect to a Eurocurrency Revolving Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as
provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing in the case of a

                                       33
<PAGE>

Dollar Loan and the 30-day LIBO Rate for Alternative Currency Loans.
Notwithstanding any contrary provision hereof, if an Event of Default has
occurred and is continuing and the Administrative Agent, at the request of the
Required Lenders, so notifies the Borrower, then, so long as an Event of Default
is continuing (i) no outstanding Revolving Borrowing may be converted to or
continued as a Eurocurrency Borrowing and (ii) unless repaid, each Eurocurrency
Revolving Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

         SECTION 2.09 Termination and Reduction of Commitments.

         (a) Unless previously terminated in accordance with the provisions of
this Agreement, the Commitments shall terminate on the earlier to occur of (i)
the Maturity Date, (ii) the date on which the Offer lapses (having not been
declared unconditional in all respects) or is withdrawn, or is referred as
provided in paragraphs (b) or (c) of Appendix I of the Press Release and (iii)
August 15, 2000 if the Offer has not by then been announced.

         (b) The Borrower may at any time terminate, or from time to time
reduce, the Commitments; provided that (i) each reduction of the Commitments
shall be in an amount that is an integral multiple of $5,000,000 and not less
than $10,000,000, (ii) the Borrower shall not terminate or reduce the
Commitments if, after giving effect to any concurrent prepayment of the Loans in
accordance with Section 2.11, the sum of the Revolving Credit Exposures plus the
aggregate principal amount of outstanding Competitive Loans would exceed the
total Commitments and (iii) during the Certain Funds Period, the Borrower shall
not terminate or reduce the Commitments below the sum of the aggregate principal
amount of then outstanding Other Borrowings and the Certain Funds Committed
Amount. The Commitments shall be permanently reduced in the amount of any
prepayment of the Loans in accordance with Section 2.11(d).

         (c) The Borrower shall notify the Administrative Agent of any election
to terminate or reduce the Commitments under paragraph (b) of this Section at
least three Business Days prior to the effective date of such termination or
reduction, specifying such election and the effective date thereof. Promptly
following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant
to this Section shall be irrevocable; provided that a notice of termination of
the Commitments delivered by the Borrower may state that such notice is
conditioned upon the effectiveness of other credit facilities, in which case
such notice may be revoked by the Borrower (by notice to the Administrative
Agent on or prior to the specified effective date) if such condition is not
satisfied. Any termination or reduction of the Commitments shall be permanent.
Each reduction of the Commitments shall be made ratably among the Lenders in
accordance with their respective Commitments.

         SECTION 2.10 Repayment of Loans; Evidence of Debt.

         (a) The Borrower hereby unconditionally promises to pay (i) to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Revolving Loan on the Maturity Date and (ii) to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Competitive Loan on the last day of the Interest Period
applicable to such Loan.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

         (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Class and Type thereof
and the Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.

         (e) Any Lender may request that Loans made by it be evidenced by a
promissory note. In such event, the Borrower shall prepare, execute and deliver
to such Lender a promissory note payable to the order of such Lender (or, if
requested by such Lender, to such Lender and its registered assigns) in the form
set out in Exhibit B hereto. Thereafter, the Loans evidenced by such promissory
note and interest thereon shall at all times (including after assignment
pursuant to Section 9.04) be represented by one or more promissory notes in such
form payable to the order of the payee named therein (or, if such promissory

         SECTION 2.11 Prepayment of Loans.

         (a) The Borrower shall have the right at any time and from time to time
to prepay any Borrowing in whole or in part, subject to prior notice in
accordance with paragraph (b) of this Section; provided that the Borrower shall
not have the right to prepay any Competitive Loan without the prior consent of
the Lender thereof.

                                       35
<PAGE>

         (b) The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurocurrency Revolving Borrowing, not later than 11:00 a.m., New
York City time, three Business Days before the date of prepayment or (ii) in the
case of prepayment of an ABR Revolving Borrowing, not later than 11:00 a.m., New
York City time, one Business Day before the date of prepayment. Each such notice
shall be irrevocable and shall specify the prepayment date and the principal
amount of each Borrowing or portion thereof to be prepaid; provided that, if a
notice of prepayment is given in connection with a conditional notice of
termination of the Commitments as contemplated by Section 2.09, then such notice
of prepayment may be revoked if such notice of termination is revoked in
accordance with Section 2.09. Promptly following receipt of any such notice
relating to a Revolving Borrowing, the Administrative Agent shall advise the
Lenders of the contents thereof. Each partial prepayment of any Revolving
Borrowing shall be in an amount that would be permitted in the case of an
advance of a Revolving Borrowing of the same Type as provided in Section 2.02.
Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans
included in the prepaid Borrowing. Prepayments shall be accompanied by accrued
interest to the extent required by Section 2.13 and any payment required under
Section 2.16.

         (c) The Borrower shall on the date, if any, specified in Section
6.07(f) repay Loans in the amounts and otherwise in all respects as provided in
such Section.

         (d) The Borrower shall prepay the Loans in the amounts and under the
circumstances set forth below, all such prepayments to be applied as more
specifically provided in subsection (b) above:

         (i) Prepayments and Reductions from Target Asset Sale Net Proceeds.
      Within five Business Days following receipt by the Borrower or a
      Subsidiary of the Net Proceeds in respect of any Target Asset Sale
      Prepayment Event, the Borrower shall prepay the Loans in an amount equal
      to such Net Proceeds except where and to the extent that:

         (A)     the Borrower is obligated under the express terms of Section
                 6.07(f) of each of the Existing Revolving Facilities to apply
                 such Net Proceeds or portion thereof (the "Repayable Amount")
                 in prepayment thereunder, in which case the Borrower shall
                 within five Business Days following receipt (i) prepay
                 hereunder any portion of such Net Proceeds in respect of which
                 it is not so obligated and (ii) apply the Repayable Amount in
                 prepayment of the Existing Revolving Facilities. The Borrower
                 undertakes to use best efforts as soon as possible and in any
                 event no more than 10 Business Days following such prepayment
                 to reborrow an amount equal to the Repayable Amount and apply
                 such proceeds in pre payment hereunder; or

                                       36
<PAGE>

         (B)     the upstreaming of such Net Proceeds by the Target or any
                 subsidiary of the Target as the case may be, whether by
                 dividend, intercompany loan or otherwise, is prohibited by UK
                 law. In the event that such prohibition arises by virtue of
                 section 151 of the Companies Act, the Borrower will to the
                 extent possible and as soon as possible, procure the compliance
                 by all relevant Subsidiaries with the Whitewash Procedure to
                 permit such prepayment.

         (ii) Prepayments and Reductions Due to Issuance of Debt. Within five
      Business Days following receipt by the Borrower or a Subsidiary of the
      cash proceeds (any such proceeds, net of underwriting discounts and
      commissions, arranger fees and other reasonable costs and expenses
      associated therewith, including reasonable legal fees and expenses, being
      "Net Debt Proceeds") from the issuance of debt securities and all
      borrowings (except and to the extent of Excluded Borrowings and except
      Indebtedness to the Borrower or any Subsidiary) of the Borrower or such
      Subsidiary after the Closing Date the Borrower shall prepay the Loans in
      an aggregate amount equal to 100% of such Net Debt Proceeds;

         (iii) Prepayments and Reductions Due to Issuance of Equity Securities.
      Within five Business Days following receipt by the Borrower or a
      Subsidiary of the cash proceeds (any such proceeds, net of underwriting
      discounts and commissions and other reasonable costs and expenses
      associated therewith, including reasonable legal fees and expenses, being
      "Net Equity Securities Proceeds") from the issuance of equity securities
      of the Borrower or such Subsidiary after the Closing Date other than (i)
      to the Borrower or any of its Subsidiaries (including, for avoidance of
      doubt, Target and its Subsidiaries) and (ii) issuances to directors,
      officers or employees or otherwise in connection with employee benefit
      arrangements, including any hybrid equity securities, the Borrower shall
      prepay the Loans in an aggregate amount equal to 100% of such Net Equity
      Securities Proceeds; and

         (iv) Prepayments Due to Currency Fluctuations. If on any Calculation
      Date the aggregate outstanding Dollar Equivalent of all Loans exceeds the
      applicable Commitment due to currency fluctuations by more than 5% of the
      Revolving Loan Commitments, the Administrative Agent shall give notice
      thereof to the Borrower and the Borrower shall on the date falling two
      Business Days thereafter prepay such Loans to the extent necessary so that
      after giving effect to such prepayment, the aggregate exposure for all
      Loans shall not exceed the Commitment. Further, if on any Calculation
      Date the sum of (i) the aggregate outstanding Dollar Equivalent of all
      Loans and (ii) the Certain Funds Committed Amount, exceeds the total
      Commitments due to currency fluctuations by more than 5% of outstanding
      Other Borrowings, the Administrative Agent shall give notice thereof to
      the Borrower and the Borrower shall on or before the date falling ten
      Business Days thereafter prepay such Loans to the

                                       37
<PAGE>

      extent necessary so that after giving effect to such prepayment the sum of
      (i) and (ii) above shall not exceed the Commitments.

         SECTION 2.12  Fees.

         (a) The Borrower agrees to pay to the Administrative Agent for the
account of each Lender a facility fee, which shall accrue at the Applicable Rate
on the daily amount of the Commitment of such Lender (whether used or unused),
as reduced in accordance with Section 2.09(b) hereof, during the period from and
including the date hereof (or, if later, the date on which such Lender is
committed hereunder) to but excluding the date on which such Commitment
terminates; provided that, if such Lender continues to have any Revolving Credit
Exposure after its Commitment terminates, then such facility fee shall continue
to accrue on the daily amount of such Lender's Revolving Credit Exposure from
and including the date on which its Commitment terminates to but excluding the
date on which such Lender ceases to have any Revolving Credit Exposure. Accrued
facility fees shall be payable in arrears on the last day of March, June,
September and December of each year and on the date on which the Commitments
terminate, commencing on the first such date to occur after the date hereof;
provided that any facility fees accruing after the date on which the Commitments
terminate shall be payable on demand. All facility fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

         (b) The Borrower agrees to pay to the Administrative Agent, for its own
account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent.

         (c) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent for distribution, in
the case of facility fees to the Lenders. Fees paid shall not be refundable
under any circumstances.

         SECTION 2.13  Interest.

         (a) The Loans comprising each ABR Borrowing shall bear interest at the
Alternate Base Rate plus the Applicable Rate.

         (b) The Loans comprising each Eurocurrency Borrowing shall bear
interest (i) in the case of a Eurocurrency Revolving Loan, at the Adjusted LIBO
Rate for the Interest Period in effect for such Borrowing plus the Applicable
Rate, or (ii) in the case of a Eurocurrency Competitive Loan, at the LIBO Rate
for the Interest Period in effect for such Borrowing plus (or minus, as
applicable) the Margin applicable to such Loan.

         (c) Each Fixed Rate Loan shall bear interest at the Fixed Rate
applicable to such Loan.

                                       38
<PAGE>

         (d) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the
rate otherwise applicable to such Loan as provided in the preceding paragraphs
of this Section or (ii) in the case of any other amount, 2% plus the rate
applicable to ABR Loans as provided in paragraph (a) of this Section.

         (e) Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and, in the case of Revolving Loans, upon
termination of the Commitments; provided that (i) interest accrued pursuant to
paragraph (d) of this Section shall be payable on demand, (ii) in the event of
any repayment or prepayment of any Loan (other than a prepayment of an ABR
Revolving Loan prior to the end of the Availability Period), accrued interest on
the principal amount repaid or prepaid shall be payable on the date of such
repayment or prepayment and (iii) in the event of any conversion of any
Eurocurrency Revolving Loan prior to the end of the current Interest Period
therefor, accrued interest on such Loan shall be payable on the effective date
of such conversion.

         (f) All interest hereunder shall be computed on the basis of a year of
360 days, except that interest computed by reference to the Alternate Base Rate
at times when the Alternate Base Rate is based on the Prime Rate or Eurocurrency
Loans denominated in Sterling shall be computed on the basis of a year of 365
days (or 366 days in a leap year), and in each case shall be payable for the
actual number of days elapsed (including the first day but excluding the last
day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall
be determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

         SECTION 2.14 Alternate Rate of Interest. If prior to the commencement
of any Interest Period for a Eurocurrency Borrowing:

         (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that adequate and reasonable means do not
exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable,
for such Interest Period; or

         (b) the Administrative Agent is advised by the Required Lenders (or, in
the case of a Eurocurrency Competitive Loan, the Lender that is required to make
such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such
Interest Period will not adequately and fairly reflect the cost to such Lenders
(or Lender) of making or maintaining their Loans (or its Loan) included in such
Borrowing for such Interest Period;

                                       39
<PAGE>

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Revolving Borrowing to, or
continuation of any Revolving Borrowing as, a Eurocurrency Borrowing shall be
ineffective, (ii) if any Borrowing Request requests a Eurocurrency Revolving
Borrowing, such Borrowing shall be made as an ABR Borrowing and (iii) any
request by the Borrower for a Eurocurrency Competitive Borrowing shall be
ineffective; provided that (A) if the circumstances giving rise to such notice
do not affect all the Lenders, then requests by the Borrower for Eurocurrency
Competitive Borrowings may be made to Lenders that are not affected thereby and
(B) if the circumstances giving rise to such notice affect only one Type of
Borrowings, then the other Type of Borrowings shall be permitted.

         SECTION 2.15  Increased Costs.

         (a) If any Change in Law shall:

         (i) impose, modify or deem applicable any reserve, special deposit or
      similar requirement against assets of, deposits with or for the account
      of, or credit extended by, any Lender (except any such reserve requirement
      reflected in the Adjusted LIBO Rate); or

         (ii) impose on any Lender or the London interbank market any other
      condition affecting this Agreement, Eurocurrency Loans or Fixed Rate Loans
      made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurocurrency Loan or Fixed Rate Loan (or of
maintaining its obligation to make any such Loan) or to reduce the amount of any
sum received or receivable by such Lender hereunder (whether of principal,
interest or otherwise), then the Borrower will pay to such Lender such
additional amount or amounts as will compensate such Lender for such additional
costs incurred or reduction suffered.

         (b) If any Lender determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such
Lender's capital or on the capital of such Lender's holding company, if any, as
a consequence of this Agreement or the Loans made by such Lender to a level
below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender or such
Lender's holding company for any such reduction suffered.

                                       40
<PAGE>

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

         (d) Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 270 days prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 270-day period referred to above shall be
extended to include the period of retroactive effect thereof.

         (e) Notwithstanding the foregoing provisions of this Section, a Lender
shall not be entitled to compensation pursuant to this Section in respect of any
Competitive Loan if the Change in Law that would otherwise entitle it to such
compensation shall have been publicly announced prior to submission of the
Competitive Bid pursuant to which such Loan was made.

         SECTION 2.16 Break Funding Payments. In the event of (a) the payment of
any principal of any Eurocurrency Loan or Fixed Rate Loan other than on the last
day of an Interest Period applicable thereto (including as a result of an Event
of Default), (b) the conversion of any Eurocurrency Loan other than on the last
day of the Interest Period applicable thereto, (c) the failure to borrow,
convert, continue or prepay any Revolving Loan on the date specified in any
notice delivered pursuant hereto (regardless of whether such notice may be
revoked under Section 2.11(b) and is revoked in accordance there with), (d) the
failure to borrow any Competitive Loan after accepting the Competitive Bid to
make such Loan, or (e) the assignment of any Eurocurrency Loan or Fixed Rate
Loan other than on the last day of the Interest Period applicable thereto as a
result of a request by the Borrower pursuant to Section 2.19, then, in any such
event, the Borrower shall compensate each Lender for the loss, cost and expense
attributable to such event. In the case of a Eurocurrency Loan, such loss, cost
or expense to any Lender shall be deemed to include an amount determined by such
Lender to be the excess, if any, of (i) the amount of interest which would have
accrued on the principal amount of such Loan had such event not occurred, at the
Adjusted LIBO Rate that would have been applicable to such Loan, for the period
from the date of such event to the last day of the then current Interest Period
therefor (or, in the case of a failure to borrow, convert or continue, for the
period that would have been the Interest Period for such Loan), over (ii) the
amount of interest which would accrue on such principal amount for such period
at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for deposits in dollars or the relevant Alternative
Currency of a comparable

                                       41
<PAGE>

amount and period from other banks in the Eurocurrency market. A certificate of
any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

         SECTION 2.17  Taxes.

         (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section) the Administrative Agent or Lender (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the
Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

         (b) In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

         (c) The Borrower shall indemnify the Administrative Agent and each
Lender, within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender on or with respect to any payment by or on account of any obligation of
the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. The
Administrative Agent and each Lender will, at the Borrower's expense, cooperate
in good faith with the Borrower in any contest as to whether or not such
Indemnified Taxes, Other Taxes, penalties, interest or expenses were correctly
or legally imposed or asserted in the event such Indemnified Taxes, Other Taxes,
penalties, interest or expenses were in the good faith judgment of the
Administrative Agent or such Lender, as the case may be, not legal or not
correctly asserted. If in connection with such contest such Indemnified Taxes,
Other Taxes, penalties, interest or expenses are refunded to the Administrative
Agent or such Lender, the Administrative Agent or such Lender will pay such
refund to the Borrower to the extent the Administrative Agent or such Lender,
determines in its sole discretion that such refund is attributable to any
Indemnified Taxes, Other Taxes, penalties, interest or expenses paid by the
Borrower and to the extent the Borrower has previously indemnified the
Administrative Agent or such Lender therefor pursuant to this Section 2.17, net
of expenses and without interest except any interest (net of taxes) included in
such refund. The Borrower shall return such refund (together with

                                       42
<PAGE>

any taxes, penalties or other charges) in the event the Administrative Agent or
such Lender is required to repay such refund. Notwithstanding the foregoing,
nothing in this Section 2.17 shall be construed to (i) entitle the Borrower or
any other Persons to any information determined by the Administrative Agent or
any Lender, in each case, in its sole discretion, to be confidential or
proprietary information of the Administrative Agent any Lender, to any tax or
financial information of the Administrative Agent or any Lender or to inspect or
review any books and records of the Administrative Agent or any Lender, or (ii)
interfere with the rights of the Administrative Agent, or any Lender to conduct
its fiscal or tax affairs in such matter as it deems fit.

A certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender or by the Administrative Agent on its own behalf or on
behalf of a Lender, shall be conclusive absent manifest error.

         (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

         (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by the Borrower as will permit such payments to be
made without withholding or at a reduced rate.

         SECTION 2.18  Payments Generally; Pro Rata Treatment; Sharing of Set-
                       -------------------------------------------------------
offs.
----

         (a) The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest, fees or of amounts payable under
Section 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon, New York City
time, on the date when due, in immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Administrative Agent, be deemed to have been received on the
next succeeding Business Day for purposes of calculating interest thereon. All
such payments shall be made to the Administrative Agent at its offices at 270
Park Avenue, New York, New York, except that payments pursuant to Sections 2.15,
2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment hereunder shall be due on a day that is not a
Business Day, the date for payment shall be extended to the next succeeding
Business Day, and, in the case of any payment accruing interest, interest
thereon

                                       43
<PAGE>

shall be payable for the period of such extension. All payments hereunder shall
be made in dollars, except for payments of principal and interest in respect of
Alternative Currency Loans, which shall be made in the relevant Alternative
Currency.

         (b) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied towards payment of interest
and fees then due hereunder, ratably among the parties entitled thereto in
accordance with the amounts of interest and fees then due to such parties.

         (c) If any Lender shall, by exercising any right of set-off or counter
claim or otherwise, obtain payment in respect of any principal of or interest on
any of its Revolving Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Revolving Loans then due and
accrued interest thereon than the proportion received by any other Lender, then
the Lender receiving such greater proportion shall purchase (for cash at face
value) participations in the Revolving Loans of other Lenders to the extent
necessary so that the benefit of all such payments shall be shared by
the Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Revolving Loans; provided that (i) if any
such participations are purchased and all or any portion of the payment giving
rise thereto is recovered, such participations shall be rescinded and the
purchase price restored to the extent of such recovery, without interest, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for
the assignment of or sale of a participation in any of its Loans to any assignee
or participant, other than to the Borrower or any Subsidiary or Affiliate
thereof (as to which the provisions of this paragraph shall apply). The Borrower
consents to the foregoing and agrees, to the extent it may effectively do so
under applicable law, that any Lender acquiring a participation pursuant to the
foregoing arrangements may exercise against the Borrower rights of set-off and
counterclaim with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such participation.

         (d) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders hereunder that the Borrower will not make
such payment, the Administrative Agent may assume that the Borrower has made
such payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders the amount due. In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally
agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the greater of the Federal Funds
Effective Rate and a rate determined by the Administrative Agent in accordance
with banking industry rules on interbank compensation.

                                       44
<PAGE>

         (e) If any Lender shall fail to make any payment required to be made by
it pursuant to Section 2.07(b) or 2.18(d), then the Administrative Agent may, in
its discretion (notwithstanding any contrary provision hereof), apply any
amounts thereafter received by the Administrative Agent for the account of such
Lender to satisfy such Lender's obligations under such Sections until all such
unsatisfied obligations are fully paid.

         SECTION 2.19 Mitigation Obligations; Replacement of Lenders.

         (a) If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

         (b) If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
or if any Lender defaults in its obligation to fund Loans hereunder, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in
Section 9.04), all its interests, rights and obligations under this Agreement
(other than any outstanding Competitive Loans held by it) to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the
prior written consent of the Administrative Agent, which consent shall not
unreasonably be withheld, (ii) such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans (other than Competitive
Loans), accrued interest thereon, accrued fees and all other amounts payable to
it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Section 2.15 or payments required to be made pursuant to
Section 2.17, such assignment will result in a reduction in such compensation or
payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment
and delegation cease to apply.

         The Borrower represents and warrants to the Lenders that:

         SECTION 3.01  Organization; Powers.

         (a) Each of the Borrower and its Subsidiaries is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to carry on its business as
now conducted and as proposed to be conducted, to enter into the Loan Documents
to which it is a party and to carry out the transactions contemplated thereby
and, except where the failure to do so, individually or in the aggregate, could
not reasonably be expected to result in a Material Adverse Effect, is qualified
to do business in, and is in good standing in, every jurisdiction where such
qualification is required.

         (b) (other than as may result from the entry into of the Loan
Documents, the Offer Documents and the documents ancillary thereto) prior to
the date of this Agreement, Newco has not undertaken any trading or incurred any
material liabilities of any nature whatsoever whether actual or contingent other
than liabilities for professional fees and any liability which would arise if
Newco were wound up.

         SECTION 3.02 Authorization; Enforceability. The Transactions affecting
the Loan Parties are within each Loan Party's corporate powers and have been
duly authorized by all necessary corporate and, if required, stockholder
action. This Agreement and each of the Loan Documents has been duly executed and
delivered by each Loan Party and constitutes a legal, valid and binding
obligation of such Loan Party, enforceable in accordance with its terms, subject
to applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

         SECTION 3.03 Governmental Approvals; No Conflicts. The Transactions
affecting the Loan Parties (a) do not require any consent or approval of,
registration or filing with, or any other action by, any Governmental Authority,
except (i) such as have been obtained or made and are in full force and effect
and, (ii) in respect only of the period from the date hereof to the Closing Date
but not thereafter, the Outstanding Approvals, (b) will not violate any
Contractual Obligation or applicable law or regulation or the charter, by-laws
or other organizational documents of any Loan Party or any of its subsidiaries
or any order of any Governmental Authority, (c) will not violate or result in a
default under any indenture, agreement or other instrument binding upon any Loan
Party or any of its subsidiaries or its assets, or give rise to a right
thereunder to require any payment to be made by any Loan Party or any of its
subsidiaries, and (d) will not result in the creation or imposition of any Lien
on any asset of any Loan Party or any of its subsidiaries.

         SECTION 3.04  Financial Condition; No Material Adverse Change.

         (a) The Borrower has heretofore furnished to the Lenders:

         (i) its consolidated balance sheet and statements of income, and cash
      flows (x) as of and for the fiscal years ended December 31, 1999 and
      December 31, 1998, reported on and audited by KPMG LLP, independent public
      accountants, and (y) as of and for the three-month period ended March 31,
      2000 certified by its chief financial officer; and

         (ii) the Target's (x) consolidated balance sheet, profit and loss
      account, statement of total recognized gains and losses and cash flow
      statement as of and for the fiscal years ended December 31, 1999 and

      independent public accoun tants, and (y) summary financial information as
      of and for the four-month period ended April 30, 2000 as provided to the
      Agent by the Borrower pursuant to Section 4.01(l).

         All of the foregoing financial statements delivered pursuant to clause
      (a)(i) above present fairly, in all material respects, the financial
      position and results of operations and cash flows of the Borrower and its
      consolidated Subsidiaries as of such dates and for such periods in
      accordance with GAAP, subject to year-end audit adjustments and the
      absence of footnotes in the case of the statements referred to in
      sub-clause (i)(y) above.

         (b) All financial statements delivered pursuant to clause (a) above,
including the related schedules and notes thereto, have been prepared in
accordance with GAAP in the case of (a)(i) and UK GAAP in the case of (a)(ii)
applied consistently throughout the periods involved. The Borrower and its
Subsidiaries and the Target and its subsidiaries do not have 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, that are not reflected in the most recent
financial statements referred to in this Section 3.04.

         (c) Since December 31, 1999, (but in the case of the Target only (and
not, for the avoidance of doubt, the Borrower or its Subsidiaries) to the
knowledge of the Borrower having made all due enquiry), there has been no event,
development or circumstance that has had or could reasonably be expected to have
a Material Adverse Effect on each of the Target and its subsidiaries, or the
Borrower and its Subsidiaries.

         SECTION 3.05 Properties.

         (a) Each of the Borrower and its Subsidiaries has good title to, or
valid leasehold interests in, all its real and personal property material to its
business, except for minor defects in title that do not interfere with its
ability to conduct its business as currently conducted or to utilize such
properties for their intended purposes.

         (b) Each of the Borrower and its Subsidiaries owns, or is licensed to
use, all trademarks, tradenames, copyrights, patents and other intellectual
property material to its business, and the use thereof by the Borrower and its
Subsidiaries does not infringe upon the rights of any other Person, except for
any such infringements that, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

         SECTION 3.06 Litigation and Environmental Matters.

         (a) There are no actions, suits or proceedings by or before any
arbitrator or Governmental Authority pending against or, to the knowledge of the
Borrower, threatened against or affecting the Borrower or any of its
Subsidiaries (i) the reasonably anticipated outcome of which would, individually
or in the aggregate, result in a Material Adverse Effect (other than the
Disclosed Matters) or (ii) that involve this Agreement or the Transactions.

         (b) Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, neither the Borrower nor any of
its Subsidiaries (i) has failed to comply with any Environmental Law or to
obtain, maintain or comply with any Environmental Permit, (ii) has become
subject to any Environmental Liability, (iii) has received notice of any
Environmental Claim or (iv) knows of any basis for any Environ mental Liability.

         (c) Since the date of this Agreement, there has been no change in the
status of the Disclosed Matters that, individually or in the aggregate, has
resulted in, or could reasonably be expected to result in, a Material Adverse
Effect.

         SECTION 3.07 Compliance with Laws and Agreements. Each of the Borrower
and its Subsidiaries is in compliance with all laws, regulations and orders of
any Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

         SECTION 3.08 Investment and Holding Company Status. Neither the
Borrower nor any of its Subsidiaries is (a) an "investment company" as defined
in, or subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

         SECTION 3.09 Taxes. Each of the Borrower and its Subsidiaries has
timely filed or caused to be filed all Tax returns and reports required to have
been filed and has paid or caused to be paid all Taxes required to have been
paid by it, except (a) Taxes that are being contested in good faith by
appropriate proceedings and for which such the Borrower or such Subsidiary, as
applicable, has set aside on its books adequate reserves or (b) to the extent
that the failure to do so could not reasonably be expected to result in a
Material Adverse Effect.

         SECTION 3.10 ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date
of the most recent financial statements reflecting such amounts, exceed by more
than $10,000,000 the fair market value of the assets of such Plan, and the
present value of all accumulated benefit obligations of all underfunded Plans
(based on the assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the date of the most recent financial
statements reflecting such amounts, exceed by more than $10,000,000 the fair
market value of the assets of all such underfunded Plans.

         SECTION 3.11 Disclosure. The Borrower has disclosed to the Lenders all
agreements, instruments and corporate or other restrictions to which it or any
of its Subsidiaries is subject, and all other matters known to it, that,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect. Neither the Offer Document nor any of the other
reports, financial statements, certificates or other information furnished by or
on behalf of any Loan Party to the Administrative Agent or any Lender in
connection with the Transactions and the negotiation of this Agreement or
delivered hereunder (as modified or supplemented by other information so
furnished) contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that, with
respect to projected financial information, the Borrower represents only that
such information was prepared in good faith based upon assumptions believed to
be reasonable at the time.

         SECTION 3.12 Scheduled Indebtedness and Scheduled Liens.

         (a) Schedule 3.12(a) sets out all the indebtedness for borrowed money
of the Target and its subsidiaries as of a recent date of which the Borrower,
having made all due enquiry is, at the date hereof, aware (the "Scheduled
Indebtedness").

         (b) Schedule 3.12(b) sets out all the Liens (other than Permitted
Encumbrances) of the Target and its subsidiaries securing the Scheduled
Indebtedness of which the Borrower having made all due enquiry is, at the date

<PAGE>

         SECTION 3.13 No Default. Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect that could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

         SECTION 3.14 Federal Regulations. No part of the proceeds of any Loans
will be used for "buying" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U as now and from time to
time hereafter in effect that would cause the Loans to be in violation of the
provisions of the Regulations of the Board. If requested by any Lender or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Lender a statement to the foregoing effect in conformity with the
requirements of Form FR G-3 or Form FR U-1, as applicable, referred to in
Regulation U.

         SECTION 3.15 Labor Matters. Except as, in the aggregate, could not
reasonably be expected to have a Material Adverse Effect, there are no strikes
or other labor disputes against any Loan Party or any of its Subsidiaries
pending or, to the knowledge of the Borrower, threatened.

         SECTION 3.16 Options. There are no outstanding subscriptions, options,
warrants, calls, rights or other agreements or commitments (other than (i) stock
options granted to employees or directors and directors' qualifying shares and
(ii) customary shareholders rights plans in effect from time to time) of any
nature relating to any Capital Stock of the Borrower or any Subsidiary, except
as created by the Loan Documents.

         SECTION 3.17 Insurance. Each Loan Party has for itself and its
Subsidiaries insurance from financially sound and reputable insurers or
maintains with such insurers valid and collectible insurance with respect to
their respective assets and businesses which is required to be obtained and
maintained by it pursuant to Section 5.05 hereof.

counsel of documentation evidencing such indebtedness and the Commitments under
the Facility are reduced by an amount equal to the debt not repaid or (ii)
repayment of such indebtedness of Target and its subsidiaries is prohibited by
applicable law or binding contractual terms, in which case commercially
reasonable efforts will be used to repay such indebtedness as promptly as

declare the Loans to be due and payable (or due and payable on demand) or
accelerate any principal amounts outstanding hereunder, howsoever described, as
a result solely of one or more Defaults or Events of Defaults described in

circumstance giving rise to such Default or Event of Default, or the result of
such Potential Event of Default or Events of Default, (i) directly relates to
Target or any of its subsidiaries (or any of their businesses, assets or
liabilities), (ii) is capable of being cured or remedied during the Clean-up
Period and (iii) arose prior to the Closing Date; provided, further, that the

                                       69
<PAGE>

Administrative Agent and the Lenders shall be entitled to exercise any and all
rights and remedies granted to them hereunder and under the Loan Documents with
respect to an occurrence or continuation of any such Default or Event of Default
after the expiration of the Clean-up Period.


                                 ARTICLE VIII
                           The Administrative Agent

         In order to expedite the transactions contemplated by this Agreement,
each of the Lenders hereby irrevocably appoints the Administrative Agent as its
agent and authorizes the Administrative Agent to take such actions on its behalf
and to exercise such powers as are delegated to the Administrative Agent by the
terms hereof, together with such actions and powers as are reasonably incidental
thereto.

         Each bank serving as the Administrative Agent hereunder shall have the
same rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and each such
bank and its Affiliates may accept deposits from, lend money to and generally
engage in any kind of business with the Borrower or any Subsidiary or other
Affiliate thereof as if it were not the Administrative Agent hereunder.

         The Administrative Agent shall not have any duties or obligations
except those expressly set forth herein. Without limiting the generality of the
foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is
continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 9.02), (c) except as expressly set forth herein, the
Administrative Agent shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to the Borrower or
any of its Subsidiaries that is communicated to or obtained by the bank serving
as the Administrative Agent or any of its Affiliates in any capacity and (d) the
Administrative Agent will upon becoming aware of the occurrence of a Default
give notice of such Default to each Lender. The Administrative Agent shall not
be liable for any action taken or not taken by it with the consent or at the
request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section
9.02) or in the absence of its own gross negligence or wilful misconduct. The
Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by the
Borrower or a Lender, and the Administrative Agent shall not be responsible for
or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agree-

                                       70
<PAGE>

ment, (ii) the contents of any certificate, report or other document delivered
hereunder or in connection here with, (iii) the performance or observance of any
of the covenants, agreements or other terms or conditions set forth herein, (iv)
the validity, enforceability, effectiveness or genuineness of this Agreement or
any other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article IV or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Administrative Agent.

         The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon. The Administrative Agent may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

         The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the
preceding paragraphs shall apply to any such sub-agent and to the Related
Parties of the Administrative Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as the Administrative
Agent.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders and the Borrower. Upon any such resignation, the
Required Lenders shall have the right, in consultation with the Borrower, to
appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after
the retiring Administrative Agent gives notice of its resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a bank with an office in New York, New York,
or an Affiliate of any such bank. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor, such successor shall succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. The fees payable by the
Borrower to a successor Administrative Agent shall be the same as those payable
to its predecessor unless otherwise agreed between the Borrower and such
successor. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.03 shall continue in effect for the
benefit of such retiring Administrative Agent, its sub-agents

                                       71
<PAGE>

and their respective Related Parties in respect of any actions taken or omitted
to be taken by any of them while it was acting as the Administrative Agent.

         Each Lender acknowledges that it has, independently and without
reliance upon any Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any related agreement or any document furnished hereunder or thereunder.

of this Agreement shall be deemed to have been given on the date of receipt.

         SECTION 9.02  Waivers; Amendments.

         (a) No failure or delay by the Administrative Agent or any Lender in
exercising any right or power hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent and the
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by the Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lender may have
had notice or knowledge of such Default at the time.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into

                                       73
<PAGE>

by the Borrower and the Required Lenders or by the Borrower and the
Administrative Agent with the consent of the Required Lenders; provided that no
such agreement shall (i) increase the Commitment of any Lender without the
written consent of such Lender, (ii) reduce the principal amount of any Loan or
reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender affected thereby, (iii) postpone the
scheduled date of payment of the principal amount of any Loan, or any interest
thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse
any such payment, or postpone the scheduled date of expiration of any
Commitment, without the written consent of each Lender affected thereby, (iv)
change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing
of payments required thereby, without the written consent of each Lender, or (v)
change any of the provisions of this Section or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights hereunder or make any
determination or grant any consent hereunder, without the written consent of
each Lender.

         SECTION 9.03  Expenses; Indemnity; Damage Waiver.

         (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent and its Affiliates, including the
reasonable fees, charges and disbursements of counsel for the Administrative
Agent, in connection with the syndication of the credit facilities provided for
herein, the preparation and administration of this Agreement or any amendments,
modifications or waivers of the provisions hereof (whether or not the
transactions contemplated hereby or thereby shall be consummated) and (ii) all
out-of-pocket expenses incurred by the Administrative Agent or any Lender,
including the fees, charges and disbursements of counsel for the Administrative
Agent or such Lender, in connection with the enforcement or protection of its
rights in connection with this Agreement, including its rights under this
Section, or in connection with the Loans made hereunder, including all such
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans.

         (b) The Borrower shall indemnify the Administrative Agent and each
Lender, and each Related Party of any of the foregoing Persons (each such Person
being called an "Indemnitee") against, and hold each Indemnitee harmless from,
any and all losses, claims, damages, liabilities and related expenses, including
the fees, charges and disbursements of any counsel for any Indemnitee, incurred
by or asserted against any Indemnitee arising out of, in connection with, or as
a result of (i) the execution or delivery of this Agreement or any agreement or
instrument contemplated hereby, the performance by the parties hereto of their
respective obligations hereunder or the consummation of the Transactions or any
other transactions contemplated hereby, (ii) any Loan or the use of the proceeds
therefrom, (iii) any actual or alleged presence or Release of Hazardous
Materials on or from any property owned or operated by the Borrower or any of
its Subsidiaries, or any Environmental Liability related in any way to the
Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim,
litigation, investigation or proceeding relating to any of the

                                       74
<PAGE>

foregoing, whether based on contract, tort or any other theory and regardless of
whether any Indemnitee is a party thereto; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

         (c) To the extent that the Borrower fails to pay any amount required to
be paid by it to the Administrative Agent under paragraph (a) or (b) of this
Section, each Lender severally agrees to pay to the Administrative Agent such
Lender's Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against the Administrative Agent in its capacity as such.

         (d) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or the use of the proceeds thereof.

         (e) All amounts due under this Section shall be payable promptly after
written demand therefor.

         SECTION 9.04  Successors and Assigns.

         (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, the Borrower may not 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 the Borrower without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

         (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans at the time owing to it); provided that (i) except
in the case of an assignment to a Lender or an Affiliate of a Lender, each of
the Borrower and the Administrative Agent must give their prior written consent
to such assignment (which consent shall in any case not be unreasonably
withheld; it being understood that it is not unreasonable to withhold consent

                                       75
<PAGE>

with respect to any proposed assignment to any financial institution having net
capital and surplus of less than $1,000,000,000 or senior, unsecured, long-term
indebtedness for borrowed money with a credit rating of less than A-), (ii)
except in the case of an assignment to a Lender or an Affiliate of a Lender or
an assignment of the entire remaining amount of the assigning Lender's
Commitment, the amount of the Commitment of the assigning Lender subject to each
such assignment (determined as of the date the Assignment and Acceptance with
respect to such assignment is delivered to the Administrative Agent) shall not
be less than $10,000,000 and after giving effect thereto, the assigning Lender
must have Commitments and Loans aggregating at least $5,000,000, unless each of
the Borrower and the Administrative Agent otherwise consent, (iii) each partial
assignment shall be made as an assignment of a proportionate part of all the
assigning Lender's rights and obligations under this Agreement, except that this
clause (iii) shall not apply to rights in respect of outstanding Competitive
Loans, (iv) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Acceptance, together with a processing
and recordation fee of $3,500, and (v) the assignee, if it shall not be a
Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire; and provided further that any consent of the Borrower otherwise
required under this paragraph shall not be required if an Event of Default under
clause (h) or (i) of Article VII has occurred and is continuing. Subject to
acceptance and recording thereof pursuant to paragraph (d) of this Section, from
and after the effective date specified in each Assignment and Acceptance the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, 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 Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance 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 2.15, 2.16, 2.17 and 9.03). Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this paragraph 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 (e) of this Section. By executing and
delivering an Assignment and Acceptance, the assigning Lender thereunder and the
assignee thereunder shall be deemed to confirm to and agree with each other and
the other parties hereto as follows: (1) such assigning Lender warrants that it
is the legal and beneficial owner of the interest being assigned thereby free
and clear of any adverse claim and that its Commitment, and the outstanding
balances of its Loans, in each case without giving effect to assignments thereof
which have not become effective, are as set forth in such Assignment and
Acceptance, (2) except as set forth in (1) above, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement, or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, any other Loan Document or any other
instrument or document furnished pursuant hereto, or the financial condition of
the Borrower or any of its Subsidiaries or the performance or observance by the
Borrower or any of its Subsidiaries of any of its obligations under this
Agreement, any Loan

                                       76
<PAGE>

Document or any other instrument or document furnished pursuant hereto, (3) such
assignee represents and warrants that it is legally authorized to enter into
such Assignment and Acceptance; (4) such assignee confirms that it has received
a copy of this Agreement, together with copies of the most recent financial
statements referred to in Section 3.04 or delivered pursuant to Section 5.01 and
such other documents and information as it has been deemed appropriate to make
its own credit analysis and decision to enter into such Assignment and
Acceptance; (5) such assignee will independently and without reliance upon any
Administrative Agent, such assigning Lender 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 decisions in taking or not taking action under
this Agreement; (6) such assignee appoints and authorizes the Administrative
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement as are delegated to the Administrative Agent by the terms
hereof, together with such powers as are reasonably incidental thereto, and (7)
such assignee agrees that it will perform in accordance with their terms all the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

         (c) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in The City of New York a
copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment 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 the Borrower, 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. The Register shall be available for inspection by the Borrower
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

         (d) Upon its receipt of a duly completed Assignment and Acceptance
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
Acceptance 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.

         (e) Any Lender may, without the consent of the Borrower 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 Commitment and the Loans
owing to it); provided that (i) such Lender's obligations under this Agreement
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations and (iii) the
Borrower, the Administrative Agent and the other Lenders shall

                                       77
<PAGE>

continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement. Any agreement or
instrument 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 or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 9.02(b) that
affects such Participant. Subject to paragraph (f) of this Section, the
Borrower agrees that each Participant shall be entitled to the benefits of
Sections 2.15, 2.16 and 2.17 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 9.08 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.18(c) as though it were a Lender.

         (f) A Participant shall not be entitled to receive any greater payment
under Section 2.15 or 2.17 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 the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as
though it were a Lender.

         (g) 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.

         SECTION 9.05 Survival. All covenants, agreements, representations and
warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any
Loans, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent or any Lender may have
had notice or knowledge of any Default or incorrect representation or warranty
at the time any credit is extended hereunder, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any fee or any other amount payable under this Agreement is outstanding and
unpaid and so long as the Commitments have not expired or terminated. The
provisions of Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive
and remain in full force and effect regardless of the consummation of the
transactions

                                       78
<PAGE>

contemplated hereby, the repayment of the Loans, the expiration or termination
of the Commitments or the termination of this Agreement or any provision hereof.

         SECTION 9.06 Counterparts; Integration; Effectiveness. This Agreement
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Administrative
Agent constitute the entire contract among the parties relating to the subject
matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof. Except as provided in
Section 4.01, this Agreement shall become effective when it shall have been
executed by the Administrative Agent and when the Administrative Agent shall
have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

         SECTION 9.07 Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

         SECTION 9.08 Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by such Lender or Affiliate to or for the credit or the account of the
Borrower against any of and all the obligations of the Borrower now or hereafter
existing under this Agreement held by such Lender, irrespective of whether or
not such Lender shall have made any demand under this Agreement and although
such obligations may be unmatured. The rights of each Lender under this Section
are in addition to other rights and remedies (including other rights of setoff)
which such Lender may have.

         SECTION 9.09  Governing Law; Jurisdiction; Consent to Service of
Process.

         (a)     This Agreement shall be construed in accordance with and
governed by the law of the State of New York.

         (b) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of

                                       79
<PAGE>

New York sitting in New York County and of the United States District Court of
the Southern District of New York, and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Administrative Agent or any Lender may otherwise have to bring
any action or proceeding relating to this Agreement against the Borrower or its
properties in the courts of any jurisdiction.

         (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any court referred to in
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         (d) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 9.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 9.11 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

<PAGE>

         SECTION 9.12 Confidentiality. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement, (e) in connection with the exercise of any remedies hereunder
or any suit, action or proceeding relating to this Agreement or the enforcement
of rights hereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (g) with the consent of the Borrower
or (h) to the extent such Information (i) becomes publicly available other than
as a result of a breach of this Section or (ii) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Borrower. For the purposes of this Section, "Information" means
all information received from the Borrower relating to the Borrower or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by the Borrower; provided that, in the case of information received
from the Borrower after the date hereof, such information is clearly identified
at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

         SECTION 9.13 Interest Rate Limitation. Notwithstanding anything herein
to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

         SECTION 9.14  Judgment Currency.

         (a) If for the purpose of obtaining judgment in any court it is
necessary to convert a sum due hereunder in one currency into another currency,
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent could purchase the first currency
with such other currency in the city in which it normally conducts its foreign
exchange operation for the first currency on the Business Day preceding the day
on which final judgment is given.

         (b) The obligation of the Borrower in respect of any sum due from it to
any Lender hereunder shall, notwithstanding any judgment in currency (the
"Judgment Currency") other than that in which such sum is denominated in
accordance with the applicable provisions of this Agreement (the "Agreement
Currency"), be discharged only to the extent that on the Business Day following
receipt by such Lender of any sum adjudged to be so due in the Judgment Currency
such Lender may in accordance with normal banking procedures purchase the
Agreement Currency with the Judgment Currency; if the amount of Agreement
Currency so purchased is less than the sum originally due to such Lender in the
Agreement Currency, the Borrower agrees notwithstanding any such judgment to
indemnify such Lender against such loss, and if the amount of the Agreement
Currency so purchased exceeds the sum originally due to any Lender, such Lender
agrees to remit to the Borrower such excess.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

                        Calculation of Additional Cost

1.    The Additional Cost shall be calculated by the Administrative Agent in
      respect of each period for which it falls to be calculated relating to an
      Alternative Currency Loan in accordance with the following formulae:


      In relation to Eurocurrency Loans denominated in Sterling:

                 CL + S(L-Z) = 0.01F
                 --------------------- =  per cent. per annum
                    100 - (C+S)

      In relation to Eurocurrency Loans denominated in an Alternative Currency:

                             0.01F
                         Y ----------- =  per cent. per annum
                              100
      Where:

      C  = The amount required to be held as a non-interest bearing cash ratio
           deposit with the Bank of England expressed as a percentage of an
           eligible institution's eligible liabilities (above any stated
           minimum).

      F  = The amount of Sterling per (pound)1,000,000 of the fee base of an
           authorised institution payable to the Financial Services Authority
           per annum (disregarding any minimum fee payable under the Fees
           Regulations).

      L  = The rate of interest per annum at which Sterling deposits of an
           amount comparable to the Loan are offered by the Administrative Agent
           to leading banks in the London Interbank Market at or about 11.00
           a.m. on the date of calculation for a period comparable to the period
           for which the Additional Cost is to be calculated.

      S  = The amount required to be placed as special deposits with the Bank
           of England, expressed as a percentage of an eligible institution's
           eligible liabilities (above any stated minimum).

      Y  = The fraction of foreign currency liabilities taken into account
           under the Fees Regulations in calculating the fee base (disregarding
           any offset for claims on non-resident offices).

      Z  = The lower of L and the rate of interest per annum paid by the Bank
           of England on special deposits at or about 11.00 a.m. on the date of
           calculation.

2.    For the purposes of calculating the Additional Cost:

                                       90
<PAGE>

      (a)  C, L, S and Z are included in the formula as numbers and not as
           percent ages, e.g. if C = 0.15 per cent. and L = 7 per cent. CL is
