      2.01 The Loans. (a) Subject to and upon the terms and conditions set forth
herein, each Bank with a Commitment severally agrees, at any time commencing on
the date hereof to but not including the Commitment Termination Date, to make
loans (each, a "Loan" and collectively, as the context requires, the "Loans") to
each Borrower in Dollars, which Loans (i) shall, at the option of such Borrower,
be Base Rate Loans or Eurocurrency Rate Loans, provided that, except as
otherwise specifically provided in Section 2.10(b), all Loans comprising the
same Borrowing shall at all times be of the same Type, and (ii) may be repaid,
prepaid and reborrowed in accordance with the provisions hereof; provided,
however, that the aggregate principal amount of Loans outstanding from any Bank
shall at no time exceed (after giving effect to the use of the proceeds of any
Loan then being made) an amount equal to the Commitment of such Bank at such
time. More than one Borrowing may occur on the same date.

      (b) Anything in this Section 2.01 to the contrary notwithstanding, the
aggregate unpaid principal amount of all Loans outstanding at the same time
shall not exceed the Total Commitment at such time.

      2.02 Minimum Amount of Each Borrowing. The aggregate principal amount of
each Borrowing hereunder shall be not less than $10,000,000 or a larger whole
multiple of $1,000,000 for each such Loan, except as required by Section
2.10(b). Borrowings of Loans of different Types or, in the case of Eurocurrency
Rate Loans, having different Interest Periods, at the same time hereunder shall
be deemed separate Borrowings.

      2.03 Notice of Borrowing. Whenever any Borrower desires to make a
Borrowing hereunder, it shall give the Administrative Agent notice thereof at
its Notice Office by noon (New York time) on the date three Business Days prior
to each Eurocurrency Rate Loan and by noon (New York time) on the date of each
Base Rate Loan. Each such notice (each a "Notice of Borrowing") shall be in the
form of Exhibit A-1, appropriately completed to specify the aggregate principal
amount of the Loans to be made pursuant to such Borrowing, the date of such
Borrowing (which shall be a Business Day), whether the Loans being made pursuant
to such Borrowing are to be maintained as Base Rate Loans or Eurocurrency Rate
Loans and, in the


                                      -11-


case of Eurocurrency Rate Loans, the Interest Period to be applicable thereto.
The Administrative Agent shall promptly give each Bank notice of such proposed
Borrowing, of such Bank's proportionate share thereof and of the other matters
required by the immediately preceding sentence to be specified in the Notice of
Borrowing.

      2.04 Disbursement of Funds. No later than 2:00 p.m. (New York time) on the
date specified in each Notice of Borrowing for Base Rate Loans and noon (New
York time) on the date specified in each Notice of Borrowing for Eurocurrency
Rate Loans, each Bank will make available, through such Bank's Applicable
Lending Office, its pro rata portion of each Borrowing requested to be made on
such date by any Borrower under Section 2.01, in immediately available funds at
the Payment Office of the Administrative Agent, and the Administrative Agent
will make available to such Borrower at its Payment Office the aggregate of the
amounts so made available by the Banks in immediately available funds. Unless
the Administrative Agent shall have been notified by any Bank prior to the date
of Borrowing that such Bank does not intend to make available to the
Administrative Agent such Bank's portion of any Borrowing to be made on such
date, the Administrative Agent may assume that such Bank has made such amount
available to the Administrative Agent on such date of Borrowing and the
Administrative Agent may, in reliance upon such assumption, make available to
the relevant Borrower a corresponding amount. If such corresponding amount is
not in fact made available to the Administrative Agent by such Bank, the
Administrative Agent shall be entitled to recover such corresponding amount from
such Bank on demand. If such Bank does not pay such corresponding amount
forthwith upon the Administrative Agent's demand therefor, the Administrative
Agent shall promptly notify the relevant Borrower and such Borrower shall
immediately pay such corresponding amount to the Administrative Agent. The
Administrative Agent shall also be entitled to recover on demand from such Bank
or the relevant Borrower, as the case may be, interest on such corresponding
amount in respect of each day from the date such corresponding amount was made
available by the Administrative Agent to such Borrower until the date such
corresponding amount is recovered by the Administrative Agent, at a rate per
annum equal to (i) if recovered from such Bank, the cost to the Administrative
Agent of funding the relevant amount and (ii) if recovered from such Borrower,
the then applicable rate for Base Rate Loans or Eurocurrency Rate Loans, as the
case may be. Nothing in this Section 2.04 shall be deemed to release any Bank
from its obligation to make Loans hereunder or to prejudice any rights which the
relevant Borrower may have against any Bank as a result of any failure by such
Bank to make Loans hereunder.

      2.05 Notes. (a) Upon request of any Bank through the Administrative Agent,
the obligation of each Borrower to pay the principal of, and interest on, the
Loans made by such Bank to such Borrower shall be evidenced by a promissory note
duly executed and delivered by such Borrower substantially in the form of
Exhibit B with blanks appropriately completed in conformity herewith (each, a
"Note" and, collectively, the "Notes").

      (b) The Note (if any) issued to each Bank shall (i) be payable to such
Bank and be dated the date of this Agreement, (ii) mature, with respect to each
Loan evidenced thereby, in the case of a Eurocurrency Rate Loan, on the last day
of its Interest Period, and in the


                                      -12-


case of a Base Rate Loan, on the Commitment Termination Date, (iii) bear
interest as provided in the appropriate clause of Section 2.08 in respect of the
Base Rate Loans and Eurocurrency Rate Loans, as the case may be, evidenced
thereby and (iv) be entitled to the benefits of this Agreement and the Guaranty.

      (c) Each Bank will note on its internal records the amount of each Loan
made by it and each payment in respect thereof and will prior to any transfer of
its Note endorse on the reverse side thereof the outstanding principal amount of
Loans evidenced thereby. Failure to make any such notation shall not affect the
relevant Borrower's obligations in respect of such Loans.

      2.06 Conversions. Each Borrower shall have the option to convert on any
Business Day all or a portion equal to at least $5,000,000 of the outstanding
principal amount of the Base Rate Loans made to such Borrower pursuant to one or
more Borrowings into a Borrowing of Eurocurrency Rate Loans, provided that (i)
no Default or Event of Default is in existence on the date of the conversion and
(ii) no conversion pursuant to this Section 2.06 shall result in a greater
number of Borrowings than is permitted under Section 2.01. Each such conversion
shall be effected by the relevant Borrower by giving the Administrative Agent at
its Notice Office prior to noon (New York time) at least three Business Days'
prior notice (a "Notice of Conversion") specifying the Base Rate Loans to be so
converted and the Interest Period to be applicable thereto. The Administrative
Agent shall give each Bank prompt notice of any such proposed conversion
affecting any of its Base Rate Loans.

      2.07 Pro Rata Borrowings. All Borrowings under this Agreement shall be
incurred from the Banks pro rata on the basis of their Commitments. It is
understood that no Bank shall be responsible for any default by any other Bank
of its obligation to make Loans hereunder and that each Bank shall be obligated
to make the Loans provided to be made by it hereunder regardless of the failure
of any other Bank to make its Loans hereunder.

      2.08 Interest. (a) Each Borrower agrees to pay interest in respect of the
unpaid principal amount of each Base Rate Loan made to such Borrower from the
date the proceeds thereof are made available to such Borrower until the maturity
thereof (whether by acceleration or otherwise) at a rate per annum which shall
be the Base Rate in effect from time to time.

      (b) Each Borrower agrees to pay interest in respect of the unpaid
principal amount of each Eurocurrency Rate Loan made to such Borrower from the
date the proceeds thereof are made available to such Borrower until the maturity
thereof (whether by acceleration or otherwise) at a rate per annum which shall,
during the Interest Period applicable thereto, be the Eurocurrency Rate for such
Interest Period plus the Applicable Margin.

      (c) Subject to Section 11.09, overdue principal and overdue interest in
respect of each Loan and any other overdue amount payable by any Borrower
hereunder shall bear interest at a rate per annum equal to 2% per annum in
excess of the Base Rate in effect from time to time; provided, however, that no
Loan shall bear interest after maturity at a rate per annum, less than 2% in
excess of the rate of interest applicable thereto at maturity.


                                      -13-


      (d) Accrued (and theretofore unpaid) interest shall be payable (i) in
respect of each Base Rate Loan, quarterly in arrears on the last Business Day of
each March, June, September and December, (ii) in respect of each Eurocurrency
Rate Loan, on the last day of the Interest Period applicable thereto and, in the
case of an Interest Period in excess of three months, on each date occurring at
three month intervals after the first day of such Interest Period, and (iii) in
respect of each Loan, on any prepayment (on the amount prepaid), at maturity
(whether by acceleration or otherwise) and, after such maturity, on demand.

      (e) On each Interest Determination Date, the Administrative Agent shall
determine the interest rate for the Eurocurrency Rate Loans for which such
determination is being made, and shall promptly notify the relevant Borrower and
the Banks thereof. Each such determination shall, absent manifest error, be
final and conclusive and binding on all parties hereto.

      2.09 Interest Periods. At the time it gives any Notice of Borrowing or
Notice of Conversion in respect of the making of, or conversion into any
Eurocurrency Rate Loan, the relevant Borrower shall have the right to elect, by
giving the Administrative Agent notice thereof, the interest period or interest
periods (each, an "Interest Period") applicable to such Eurocurrency Rate Loan,
each of which shall, at the option of such Borrower, be a one, two, three, six
or (subject to availability as determined by 100% of the Banks) nine month
period or, (subject to availability as determined by 100% of the Banks) if such
Eurocurrency Rate Loan is a Term Loan made pursuant to Section 3.05 hereof,
twelve month period, provided that: (i) all Eurocurrency Rate Loans comprising a
Borrowing shall at all times have the same Interest Period except as otherwise
required by Section 2.10(b); (ii) the Interest Period for any Eurocurrency Rate
Loan shall commence on the date of Borrowing of such Loan (including the date of
any conversion of a Base Rate Loan into Eurodollar Rate Loan); (iii) if the
Interest Period relating to a Eurocurrency Rate Loan begins on a day for which
there is no numerically corresponding day in the calendar month at the end of
such Interest Period, such Interest Period shall end on the last Business Day of
such calendar month; (iv) if any Interest Period would otherwise expire on a day
which is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day; provided, however, that if the Interest Period for a
Eurocurrency Rate Loan would otherwise expire on a day which is not a Business
Day but is a day of the month after which no further Business Day occurs in such
month, such Interest Period shall expire on the next preceding Business Day; and
(v) no Interest Period shall extend beyond the Commitment Termination Date.

      2.10 Increased Costs, Illegality, etc. (a) In the event that any Bank
shall have determined (which determination shall, absent manifest error, be
final and conclusive and binding upon all parties hereto but, with respect to
clause (i) below, may be made only by the Administrative Agent):

            (i) on any Interest Determination Date that, by reason of any
      changes arising after the date of this Agreement affecting the London
      interbank market for deposits in


                                      -14-

      applicable interest rate on the basis provided for in the definition of
      Eurocurrency Rate; or

            (ii) at any time, that such Bank shall incur increased costs or
      reductions in the amounts received or receivable hereunder with respect to
      any Eurocurrency Rate Loan because of (x) any change since the date hereof

      (whether or not having the force of law) (or in the interpretation or
      administration thereof and including the introduction of any new law or
      governmental rule, regulation, order or request), such as, for example,
      but not limited to, (1) a change in the basis of taxation of payments to
      any Bank or its Applicable Lending office of the principal of or interest
      on the Notes or any other amounts payable hereunder (except for changes in
      the rate of tax on, or determined by reference to, the net income or
      profits of such Bank or its Applicable Lending Office imposed by any
      jurisdiction in which its principal office or Applicable Lending Office is
      located) or (2) a change in official reserve requirements, but, in all
      events, excluding reserves required under Regulation D to the extent
      included in the computation of the Eurocurrency Rate, and/or (y) other
      circumstances affecting such Bank or the interbank Eurocurrency market, or
      the position of such Bank in such market; or

            (iii) at any time, that the making of any Eurocurrency Rate Loan has
      been made (x) unlawful by any law or governmental rule, regulation or
      order, (y) impossible by compliance by such Bank with any governmental
      request (whether or not having force of law) or (z) impracticable as a
      result of a contingency occurring after the date of this Agreement which
      materially and adversely affects the London interbank market for Dollar
      deposits;

then, and in any such event, such Bank (or the Administrative Agent, in the case
of clause (i) above) shall promptly give notice (by telephone confirmed in
writing) to the Borrowers, accompanied by an explanation of the basis therefor,
and, except in the case of clause (i) above, to the Administrative Agent of such
determination (which notice the Administrative Agent shall promptly transmit to
each of the other Banks). Thereafter (x) in the case of clause (i) above,
Eurocurrency Rate Loans of the maturities identified by the Administrative Agent
in such notice as unavailable shall no longer be available until such time as
the Administrative Agent notifies the relevant Borrower and the Banks that the
circumstances giving rise to such notice by the Administrative Agent no longer
exist, and any Notice of Borrowing or Notice of Conversion given by the relevant
Borrower with respect to its affected Eurocurrency Rate Loans which have not yet
been incurred (including by way of conversion) shall be deemed rescinded by such
Borrower, (y) in the case of clause (ii) above, the Borrower to whom the
Eurocurrency Rate Loan was made shall pay to such Bank, upon written demand
therefor, such additional amounts (in the form of an increased rate of, or a
different method of calculating, interest or otherwise as such Bank in its sole
discretion shall determine) as shall be required to compensate such Bank for
such increased costs or reductions in amounts received or receivable hereunder
(a written notice as to the additional amounts owed to such Bank, showing the
basis for the calculation thereof, certified to such Borrower by such Bank
shall, absent manifest error, be final and


                                      -15-


conclusive and binding on all the parties hereto) and (z) in the case of clause
(iii) above, take one of the actions specified in Section 2.10(b) as promptly as
possible and, in any event, within the time period required by law.

      (b) At any time that any Eurocurrency Rate Loan is affected by the
circumstances described in Section 2.10(a)(ii) or (iii), the Borrower to whom
such Loan was made may (and in the case of a Eurocurrency Rate Loan affected by
the circumstances described in Section 2.10(a)(iii) shall) either (i) if the
affected Loan is then being made initially or pursuant to a conversion cancel
said Borrowing by giving the Administrative Agent telephonic notice (confirmed
in writing) of the cancellation on the same date that such Borrower was notified
by the Bank or the Administrative Agent pursuant to Section 2.10(a)(ii) or (iii)
or (ii) if the affected Eurocurrency Rate Loan is then outstanding, upon at
least three Business Days' written notice to the Administrative Agent, prepay
the Eurocurrency Rate Loans of the affected Bank and reborrow the same as Base
Rate Loans, provided that, if more than one Bank is affected at any time, then
all affected Banks must be treated the same pursuant to this Section 2.10(b).

      (c) If any Bank determines at any time that any applicable law or
governmental rule, regulation order or request (whether or not having the force
of law) concerning capital adequacy, or any change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency, which shall have become effective or applicable after the date hereof,
will have the effect of increasing the amount of capital required or expected to
be maintained by such Bank or a holding company of which such Bank is a
Subsidiary based on the existence of such Bank's Commitment hereunder or its
obligations hereunder, then the Borrowers shall pay to such Bank upon its
written demand therefor, such additional amounts as shall be required to
compensate such Bank or such holding company for the increased cost to such Bank
as a result of such increase of capital; such obligations of the Borrowers shall
be joint and several. In determining such additional amounts, each Bank will act
reasonably and in good faith and will use averaging and attribution methods
which are reasonable, provided that such Bank's determination of compensation
owing under this Section 2.10(c) shall, absent manifest error, be final and
conclusive and binding on all the parties hereto. Each Bank, upon determining
that any additional amounts will be payable pursuant to this Section 2.10(c),
will give prompt written notice thereof to the Borrowers, which notice shall
show the basis for calculation of such additional amounts, although the failure
to give any such notice shall not release or diminish any of the Borrowers'
obligations to pay additional amounts pursuant to this Section 2.10(c), absent
manifest error.

      2.11 Compensation. Each Borrower shall compensate each Bank, upon its
written request (which request shall set forth the basis for requesting such
compensation), for all reasonable losses, expenses and liabilities (including,
without limitation, any loss, expense or liability incurred by reason of the
liquidation or reemployment of deposits or other funds required by such Bank to
fund its Eurocurrency Rate Loans) which such Bank may sustain: (i) if for any
reason (other than a default by such Bank or the Administrative Agent) a
Borrowing of Eurocurrency Rate Loans does not occur on a date specified therefor
in a Notice of Borrowing or Notice of Conversion (whether or not withdrawn by
the relevant Borrower or deemed withdrawn


                                      -16-


pursuant to Section 2.10(a)); (ii) if any repayment (including any repayment
made pursuant to Section 2.04 and any prepayment made pursuant to Section 4.01)
occurs on a date which is not the last day of the Interest Period with respect
thereto; (iii) if any prepayment of any of its Eurocurrency Rate Loans is not
made on any date specified in a notice of prepayment given by the relevant
Borrower; or (iv) as a consequence of (x) any other default by the relevant
Borrower to repay its Loans when required by the terms of this Agreement or any
Note of such Bank or (y) any prepayment made pursuant to Section 2.10(b).

      2.12 Change of Applicable Lending Office. Each Bank agrees that, upon the
occurrence of any event giving rise to the operation of or a payment obligation
of any Borrower under Section 2.10(a)(ii) or (iii), 2.10(c) or 4.03 with respect
to such Bank, such Bank will, if requested by any of the Borrowers, use its best
efforts to designate another Applicable Lending Office for any Loans affected by
such event, with the object of avoiding the consequence of the event giving rise
to the operation of any such Section; provided that no such designation shall be
made if, in the reasonable judgment of such Bank, such Bank would suffer any
administrative, economic, legal, tax or regulatory disadvantage. Nothing in this
Section 2.12 shall affect or postpone any of the obligations of the Borrowers or
the right of any Bank provided in Section 2.10 or 4.03.

      Section 3. Fees; Termination or Reduction of Commitments; Commitment
Termination Date; Extension of Commitments; Increase of Commitments.

      3.01 Fees. (a) The Borrowers jointly and severally agree to pay to the
Administrative Agent on the dates set forth below, for distribution to the
Banks, a facility fee (the "Facility Fee") for the period from the date of this
Agreement until the Commitment Termination Date (or such earlier date as the
Total Commitment shall have been terminated) computed at the Applicable Facility
Fee Rate on the Total Commitment. Accrued Facility Fees shall be due and payable
quarterly in arrears on the third Business Day of each April, July, October and
January of each year, for the calendar quarter ending most recently prior to
such payment date, and on the Commitment Termination Date or upon such earlier
date as the Total Commitment shall be terminated.

      (b) The Borrowers jointly and severally agree to pay to the Administrative
Agent on the date of this Agreement, for distribution to each Bank, such fees as
may be agreed in writing between the Borrowers, the Administrative Agent and the
Banks.

      (c) The Borrowers shall pay to the Administrative Agent, for its own
account, such fees as may be agreed to from time to time between the Borrowers
and the Administrative Agent.

      3.02 Termination or Reduction of Commitments. (a) On the Commitment
Termination Date, the Total Commitment (and the Commitment of each Bank) shall
terminate in its entirety.


                                      -17-


      (b) Upon at least five Business Days' prior notice to the Administrative
Agent at its Notice Office (which notice the Administrative Agent shall promptly
transmit to each of the Banks), the Guarantor shall have the right, without
premium or penalty, to reduce or terminate the Total Commitment in whole or in
part, in integral multiples of $10,000,000 or lesser whole multiples of
$1,000,000; provided that any such reduction or termination must be applied to
reduce the Total Commitment on a pro rata basis and (ii) no such reduction of
the Total Commitment shall reduce the Total Commitment to less than the
aggregate amount of the Loans then outstanding.

      3.03 Commitment Termination Date; Extension of Commitments. (a) The
"Commitment Termination Date" shall be April 24, 2003 or such later date to
which the Commitment Termination Date has been extended pursuant to Section
3.03(b).

      (b) (i) The Guarantor may, by notice to the Administrative Agent (which
shall promptly so notify the Banks) given not earlier than 60 days and not later
than 45 days before the Commitment Termination Date then in effect (the
"Existing Commitment Termination Date"), request that the Banks extend the
Commitment Termination Date for an additional 364 days from the Existing
Commitment Termination Date. Such request shall be accompanied by a certificate
of a senior officer of the Guarantor stating that no Default or Event of Default
has occurred and is continuing and that since the date of the annual
consolidated financial statements received by the Banks pursuant to Section 7(a)
of the Guaranty most immediately prior to the date of such request, there has
been no material adverse change in the business, operations, property, assets,
condition (financial or otherwise) or (to the knowledge of the Guarantor)
prospects of the Guarantor or of the Guarantor and its Subsidiaries taken as a
whole. Each Bank which, in its sole discretion, agrees to so extend the
Commitment Termination Date and its Commitment (an "Extending Bank") shall
notify the Administrative Agent in writing of such Bank's agreement to such
extension not earlier than 45 days and not later than 35 days prior to the
Existing Commitment Termination Date, such notice to be revocable until the
Consent Date, whereupon it will become irrevocable. Any Bank that fails to so
notify the Administrative Agent shall be deemed to have declined to agree to the
requested extension (such Banks, together with such Banks as shall have notified
the Administrative Agent of their decision not to so extend the Commitment
Termination Date and their respective Commitments, the "Non-Extending Banks").
The Administrative Agent shall promptly, and in any event not later than 30 days
prior to the Existing Commitment Termination Date (the "Consent Date"), notify
the Guarantor of the Banks' respective decisions.

      (ii) The Guarantor shall have the right, during the period commencing on
the Consent Date and ending three Business Days prior to the Existing Commitment
Termination Date (the "Determination Date"), to replace the Commitments of the
Non-Extending Banks with such additional Commitments as the Extending Banks may
irrevocably agree, by notice to the Administrative Agent, to make. The
Administrative Agent shall promptly give the Guarantor notice of any such
irrevocable agreement. If the aggregate amount of such additional Commitments
from Extending Banks is less than the aggregate amount of the Commitments of the
Non-Extending Banks, the Guarantor shall have the right to add to this


                                      -18-


Agreement one or more new banks to replace such difference in Commitments (each
Extending Bank so agreeing and each such new bank, an "Additional Commitment
Bank"). Each Additional Commitment Bank shall enter into an agreement in form
and substance satisfactory to the Guarantor and the Administrative Agent
pursuant to which such Additional Commitment Bank shall, effective as of the
Existing Commitment Termination Date, have undertaken a Commitment (which, if
such Additional Commitment Bank is an Extending Bank, shall be in addition to
such Extending Bank's Commitment hereunder on such date).

      (iii) If on the Determination Date (x) the sum of the total Commitments of
the Extending Banks and the total Commitments of the Additional Commitment Banks
is more than 50% of the Commitments in effect immediately prior to the Existing
Commitment Termination Date and (y) no Default or Event of Default has occurred
and is continuing, then, effective as of the Existing Commitment Termination
Date, the Commitment Termination Date shall be extended to the date 364 days
after the Existing Commitment Termination Date (except that, if the date to
which the Commitment Termination Date is to be extended is not a Business Day,
the Commitment Termination Date as so extended shall be the next preceding
Business Day) and each Additional Commitment Bank shall thereupon become a
"Bank" for all purposes of this Agreement, the Commitment of each Additional
Commitment Bank which is an Extending Bank shall be increased in accordance with
its agreement referred to in Section 3.03(b)(ii) and the respective Commitments
of the other Extending Banks shall continue to be as they were before such
extension became effective. The Administrative Agent shall promptly give the
Banks, the Borrowers and the Guarantor written notice of each extension effected
pursuant to this Section 3.03, the post-extension levels of the Commitments of
the various Banks and the Commitment Termination Date as extended.

      (iv) The Commitment of each Non-Extending Bank shall terminate on the
Existing Commitment Termination Date and each Non-Extending Bank shall be paid
in full all amounts owing to it hereunder and remaining unpaid on or before the
Existing Commitment Termination Date.

      3.04 Increase of Commitments. The Guarantor shall have the right, at any
time prior to the then Existing Commitment Termination Date, without the consent
of the Required Banks, to effect an increase or increases in the Total
Commitment to any amount up to $1,800,000,000; provided that (i) each increase
shall be in a minimum amount of $1,000,000 and multiples of $1,000,000 in excess
thereof; (ii) no Default or Event of Default has occurred and is continuing; and
(iii) one or more of the existing Banks agree, but are not required to agree, to
increase their respective Commitments hereunder and/or one or more new banks,
satisfactory to the Guarantor and reasonably satisfactory to the Administrative
Agent, agree to provide Commitments hereunder. Notice from the Guarantor
requesting such increase shall be given to the Banks, with a copy to the
Administrative Agent, at least three Business Days before the proposed effective
date for such increase. An increase in the Total Commitments pursuant to this
Section 3.04 shall not, however, be permitted if the Total Commitment shall have
been reduced pursuant to Section 3.02(b) during the preceding four months.


                                      -19-


      3.05 Term Loan Election. (a) The Guarantor may, by delivering to the
Administrative Agent a notice (a "Notice of Election of Term Option")
substantially in the form of Exhibit A-2 hereto, not more than 30 nor less than
5 Business Days before the Existing Commitment Termination Date, elect that all
of the Loans of each Bank to a Borrower outstanding as at the close of business
New York time on such Existing Commitment Termination Date be converted,
effective at such time, to a term loan (a "Term Loan") payable by such Borrower
to such Bank, which Term Loan shall (i) be in a principal amount equal to the
aggregate outstanding principal amount of such Loans, (ii) mature on the date
(the "Final Maturity Date") that is the earlier of (x) the date one year after
such Existing Commitment Termination Date or (y) the date specified by the
Guarantor in such Notice of Election of Term Option (and each outstanding Note
shall automatically be deemed amended accordingly), (iii) bear interest, until
the payment in full thereof, at the rates provided for in Section 2.08 and
otherwise constitute a "Loan" for all purposes of this Agreement and a
"Guaranteed Obligation" for all purposes of the Guaranty and (iv) at the option
of the Guarantor be Base Rate Loans or Eurocurrency Rate Loans; provided that
the election provided for in this Section 3.05 shall not take effect if, on the
date of the Notice of Election of Term Option or on the Existing Commitment
Termination Date, a Default or Event of Default has occurred and is continuing.
Upon the effectiveness of the conversion provided for in this Section 3.05,
Section 2.01(a)(ii) shall cease to be in effect, and each Borrower agrees that
it will, forthwith upon the request of any Bank through the Administrative
Agent, issue a new promissory note (a "Term Note") in favor of such Bank in
substantially the form of Exhibit B to the Amendment and Restatement in the
amount of the Term Loan of such Bank to such Borrower provided herein, in
exchange for the Note or Notes held by such Bank (which shall be promptly
returned to the Guarantor, through the Administrative Agent, marked
"Cancelled"), or, upon presentation of evidence to the reasonable satisfaction
of the Administrative Agent (in the Administrative Agent's sole discretion) of
the loss, destruction or theft of the Note or Notes held by such Bank, and upon
delivery to the Administrative Agent, for the benefit of the Borrower or
Borrowers having issued such Note or Notes, an indemnity, in form and substance
satisfactory to such Borrower or Borrowers, made by such Bank and holding such
Borrower or Borrowers harmless, in lieu of any such lost, destroyed or stolen
Note or Notes, which Term Note shall be deemed to be a "Note" for all purposes
of this Agreement and of the Guaranty.

      (b) The Guarantor shall, in the case of any Eurocurrency Rate Loan made
pursuant to a Notice of Election of Term Option as provided in this Section 3.05
or pursuant to the conversion of a Term Loan which is a Base Rate Loan as
provided in Section 2.06 or in the case of the continuation of any Eurocurrency
Rate Loan which is a Term Loan, give notice to the Administrative Agent at its
Notice Office by noon (New York time) on that date three Business Days prior to
the making, conversion or continuation of such Eurocurrency Rate Loan, as the
case may be, stating its election of the Interest Period to be applied to such
Eurocurrency Rate Loan, provided, however, that: (i) the Interest Period for any
Eurocurrency Rate Loan which is a Term Loan shall commence on the date such
Eurocurrency Rate Loan is made, converted or continued, (ii) if the Interest
Period relating to a Eurocurrency Rate Loan which is a Term Loan begins on a day
for which there is no numerically corresponding day in the calendar month at the
end of such Interest Period, such Interest Period shall end on the last Business
Day


                                      -20-


of such calendar month, (iii) if any Interest Period relating to a Eurocurrency
Rate Loan which is a Term Loan would otherwise expire on a day which is not a
Business Day, such Interest Period shall expire on the next succeeding Business
Day, provided, however, that if the Interest Period relating to a Eurocurrency
Rate Loan which is a Term Loan would otherwise expire on a day which is not a
Business Day but is a day of the month after which no further Business Day
occurs in such month, such Interest Period shall expire on the next preceding
Business Day and (iv) no Interest Period relating to a Eurocurrency Rate Loan
which is a Term Loan may be elected or deemed elected by the Guarantor if it
would extend beyond the Final Maturity Date. If any such Interest Period would
extend beyond the Final Maturity Date, then such Interest Period shall end on
the Final Maturity Date. If the Guarantor fails to timely give such notice of
Interest Period respecting any Term Loan to the Administrative Agent then the
Guarantor shall be deemed to have elected that the Term Loan shall be a Base
Rate Loan, provided that, notwithstanding Section 2.06(i) hereof, any such Base
Rate Loan so deemed elected may be converted into a Eurocurrency Rate Loan upon
delivery by the Borrower of a Notice of Conversion respecting such Base Rate
Loan to the Administrative Agent at its Notice Office prior to noon (New York
time) at least three Business Days' prior to the effectiveness of such
conversion pursuant to Section 2.06."

      Section 4. Prepayments; Payments.

      4.01 Voluntary Prepayments. Each Borrower shall have the right to prepay
the Loans without premium or penalty, in whole or in part from time to time on
the following terms and conditions: (i) such Borrower shall give the
Administrative Agent at its Notice Office at least two Business Days' prior
notice (in the case of Eurocurrency Rate Loans) and same-day prior notice (in
the case of Base Rate Loans) of its intent to prepay the Loans, the amount of
such prepayment, the Types of Loans to be prepaid, and, in the case of
Eurocurrency Rate Loans, the specific Borrowing or Borrowings pursuant to which
made, which notice the Administrative Agent shall promptly transmit to each of
the Banks; (ii) each prepayment shall be in an aggregate principal amount of at
least $1,000,000 in the case of Base Rate Loans and $5,000,000 in the case of
Eurocurrency Rate Loans; provided that no partial prepayment made pursuant to
any Borrowing shall reduce the outstanding Loans made pursuant to such Borrowing
to an amount less than $1,000,000 in the case of Base Rate Loans and $5,000,000
in the case of Eurocurrency Rate Loans; (iii) prepayments of Eurocurrency Rate
Loans made pursuant to this Section 4.01 may only be made if at the time of such
prepayment such Borrower shall have paid in full all amounts requested by any of
the Banks pursuant to Section 2.11; and (iv) each prepayment in respect of any
Loans made pursuant to a Borrowing shall be applied pro rata among such Loans.

      4.02 Method and Place of Payment. Except as otherwise specifically
provided herein, all payments under this Agreement or any Note shall be made to
the Administrative Agent for account of the Bank or Banks entitled thereto not
later than 3:00 p.m. (New York City time) on the date when due and shall be made
in Dollars in immediately available funds at the Payment Office of the
Administrative Agent. Whenever any payment to be made hereunder or under any
Note shall be stated to be due on a day which is not a Business Day, the due
date


                                      -21-


thereof shall be extended to the next succeeding Business Day and, with respect
to payments of principal, interest shall be payable at the applicable rate
during such extension.

      4.03 Net Payments. (a) All payments made by the Borrowers hereunder or
under any Note will be made without setoff, counterclaim or other defense. All
such payments will be made free and clear of, and without deduction or
withholding for, any present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by any
jurisdiction or by any political subdivision or taxing authority thereof or
therein (but excluding, except as provided below, any tax imposed on or measured
by the net income of a Bank pursuant to the laws of the jurisdiction (or any
political subdivision or taxing authority thereof or therein) in which the
principal office or Applicable Lending Office of such Bank is located ("Excluded
Taxes") and all interest, penalties or similar liabilities with respect thereto
(collectively, "Taxes"). The Borrowers shall reimburse each Bank, upon the
written request of such Bank, for Excluded Taxes in respect of amounts paid to
or on behalf of such Bank pursuant to the preceding sentence. If any Taxes are
so levied or imposed, the Borrowers agree to pay the full amount of such Taxes
and such additional amounts as may be necessary so that every payment of all
amounts due hereunder or under any Note, after withholding or deduction for or
on account of any Taxes, will not be less than the amount provided for herein or
in such Note. The Borrowers will furnish to the Administrative Agent within 45
days after the date the payment of any Taxes is due pursuant to applicable law
certified copies of tax receipts evidencing such payment by the Borrowers. The
Borrowers will indemnify and hold harmless each Bank, and reimburse such Bank
upon its written request, for the amount of any Taxes so levied or imposed and
paid by such Bank.

      (b) Each Bank shall designate an Applicable Lending Office that, on the
date of this Agreement or (in the case of any Person that becomes a Bank
hereunder by means of an assignment) on the date that such Bank becomes a party
hereto, is entitled to a zero rate of United States withholding tax on all
payments made hereunder by OFI and OCI. On the date of this Agreement, each Bank
organized under the laws of a jurisdiction outside the United States has
provided OFI and OCI with the forms prescribed by the Internal Revenue Service
of the United States (currently Forms W-8BEN or W-8ECI) certifying such Bank's
exemption from United States withholding taxes with respect to all payments to
be made to such Bank hereunder and under the Notes as at the date of such
certificate. Each Bank shall provide such forms (or appropriate replacement
forms) on an updated basis from time to time if requested by OFI or OCI. Unless
the Borrowers have received forms or other documents satisfactory to them
indicating that payments hereunder or under any Note are not subject to
withholding tax or are subject to such tax at a rate reduced by an applicable
tax treaty, OFI and OCI shall withhold taxes from such payments at the
applicable statutory rate in the case of payments to or for any Bank organized
under the laws of a jurisdiction outside the United States. If any Bank
organized under the laws of a jurisdiction outside the United States fails to
provide OFI and OCI, with the prescribed forms referred to in the second, third
and fourth sentences of this Section 4.03(b), and notwithstanding Section 11.14,
the Borrowers shall not be required to compensate such Bank under Section
4.03(a) for the amount of taxes withheld pursuant to the immediately preceding
sentence; provided that this sentence shall be inapplicable to any Bank that is
not able to make


                                      -22-


the certification set forth in such prescribed forms as a result of a change in
United States federal income tax law, regulation or interpretation occurring
after the date of this Agreement, or to an amendment, modification or revocation
of an applicable tax treaty or a change in official position regarding the
application or interpretation thereof, in each case, occurring after the date
hereof.

      (c) In respect of Loans to OFP, each Bank shall designate an Applicable
Lending Office that, on the date of this Agreement or (in the case of any Person
that becomes a Bank hereunder by means of an assignment) on the date such Bank
becomes a party hereto is either (i) within the charge to United Kingdom
corporation tax in respect of interest in respect of an advance by a person that
was a bank (for the purposes of Section 349 Income and Corporation Taxes Act
1988) at the time the advance was made; or (ii) resident in a country with which
the United Kingdom has a double taxation agreement which makes provision for
full exemption from United Kingdom taxation on interest and does not carry on
business in the United Kingdom through a permanent establishment with which the
payment is effectively connected (each such bank which is so resident being
hereinafter in this Section 4.03 referred to as a "Treaty Lender"). If any Bank
ceases to be within clause (i) or (ii) above other than by reason of any change
after the date of this Agreement in (or in the interpretation, administration or
application of) any law or double taxation agreement or any published practice
or concession of any relevant taxing authority, the Borrowers shall not be
required to compensate such Bank under Section 4.03(a) for the amount of taxes
withheld pursuant to the immediately preceding sentence. Any Bank within clause
(ii) above shall cooperate with OFP in promptly completing any procedural
formalities necessary for OFP to obtain authorization to make interest payments
without deduction for UK income tax.

      (d) Each Treaty Lender irrevocably appoints the Administrative Agent to
Act as syndicate manager under, and authorizes the Administrative Agent to
operate, and take any action necessary or desirable under, the PTR Scheme in
connection with the Facility. Each Treaty Lender shall cooperate with the
Administrative Agent in completing any procedural formalities necessary under
the PTR Scheme, and shall promptly supply to the Administrative Agent such
information as the Administrative Agent may request in connection with the
operation of the PTR Scheme. Each Treaty Lender without limiting the liability
of any Borrower under this Agreement, shall, within five Business Days of
demand, indemnify the Administrative Agent for any liability or loss incurred by
the Administrative Agent as a result of the Administrative Agent acting as
syndicate manager under the PTR Scheme in connection with the Treaty Lender's
participation in any Loan (except to the extent that the liability or loss
arises directly from the Administrative Agent's gross negligence of willful
misconduct). Each Treaty Lender shall, within five Business Days of demand,
indemnify each Borrower for any Tax which such Borrower becomes liable to pay in
respect of any payments made to such Treaty Lender arising as a result of any
incorrect information supplied by such Treaty Lender which results in a
provisional authority issued by the UK Inland Revenue under the PTR Scheme being
withdrawn. Each Borrower acknowledges that it is fully aware of its contingent
obligations under the PTR Scheme and shall (i) promptly supply to the
Administrative Agent such information as the Administrative Agent may request in
connection with the operation of the PTR Scheme; and (ii) act in accordance with
any provisional notice issued by the UK Inland Revenue under the PTR


                                      -23-


Scheme. The Administrative Agent agrees to provide, as soon as reasonably
practicable, a copy of any provisional authority issued to it under the PTR
Scheme in connection with any Loan to those Borrowers specified in such
provisional authority. Each of the Borrowers, the Treaty Lenders and the
Administrative Agent acknowledges that the Administrative Agent: (i) is entitled
to rely completely upon information provided to it in connection with this
clause; (ii) is not obliged to undertake any inquiry into the accuracy of such
information nor into the status of the Treaty Lender or, as the case may be,
Borrower providing such information; and (iii) shall have no liability to any
person for the accuracy of any information it submits to the UK Inland Revenue
in connection with this clause.

      Section 5. Conditions Precedent.

      5.01 Effectiveness. The effectiveness of each Bank's Commitment under this
Agreement is subject to the satisfaction of the following conditions on the date
of this Agreement or such other date as is specified below:

      (a) Notes. If requested by any Bank pursuant to Section 2.05(a), there
shall have been delivered to the Administrative Agent for account of such Bank a
Note issued by each Borrower which is to evidence such Bank's Loan to such
Borrower.

      (b) Opinions of Counsel. For OFI and OCI, the Administrative Agent shall
have received (i) from Dewey Ballantine LLP, special New York counsel to OFI,
OCI and the Guarantor, an opinion addressed to each of the Banks substantially

Administrative Agent, be opined upon by the General Counsel of the Guarantor),
and covering such other matters incident to the transactions contemplated herein
as any Bank may reasonably request, and (ii) from Milbank, Tweed, Hadley &
McCloy LLP, special New York counsel to Citibank, an opinion addressed to each

from Dewey Ballantine LLP, special New York counsel to OFP, an opinion addressed
to each of the Banks substantially in the form of Exhibit C-3 and covering such
other matters incident to the transactions contemplated herein as any Bank may

Loans of any Bank) and also after giving effect thereto (i) there shall exist no
Default and (ii) all representations and warranties contained herein or in the

      6.01 Corporate Status. Each of the Borrowers and its Subsidiaries (i) is a
duly organized and validly existing corporation in good standing under the laws
of the jurisdiction of its incorporation, (ii) has the power and authority to
own its property and assets and to transact the business in which it is engaged
and (iii) is duly qualified as a foreign corporation and in good standing in
each jurisdiction where the ownership, leasing or operation of property or the
conduct of its business requires such qualification, except where the failure to
be so qualified could not have a material adverse effect on the business,
operations, property, assets, condition (financial or otherwise) or (to the
knowledge of such Borrower) prospects of such Borrower or of such Borrower and
its Subsidiaries taken as a whole.


                                      -26-


      6.02 Corporate Power and Authority. Each Borrower has the corporate power
to execute, deliver and perform the terms and provisions of each of the Credit
Documents to which it is party and has taken all necessary corporate action to
authorize the execution, delivery and performance by it of each of such Credit
Documents. Such Borrower has duly executed and delivered each of the Credit
Documents to which it is party, and each of such Credit Documents constitutes
its legal, valid and binding obligation enforceable in accordance with its terms
except as the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization or other similar laws affecting creditors' rights
generally and by general equitable principles (regardless of whether the issue
of enforceability is considered in a proceeding in equity or at law).

      6.03 No Violation. Neither the execution, delivery or performance by any
Borrower of the Credit Documents to which it is a party, nor compliance by it
with the terms and provisions thereof, (i) will contravene any provision of any
law, statute, rule or regulation or any order, writ, injunction or decree of any
court or governmental instrumentality, (ii) will conflict or be inconsistent
with or result in any breach of any of the terms, covenants, conditions or
provisions of, or constitute a default under, or result in the creation or any
indenture, mortgage, deed of trust, credit agreement, loan agreement or any
other agreement, contract or instrument to which such Borrower or any of its
Subsidiaries is a party or by which it or any of its property or assets is bound
or to which it may be subject or (iii) will violate any provision of the
Certificate of Incorporation, By-Laws or other comparable corporate charter
documents of such Borrower or any of its Subsidiaries.

      6.04 Governmental Approvals. No order, consent, approval, license,
authorization or validation of, or filing, recording or registration with
(except as have been obtained or made prior to the date hereof), or exemption
by, any governmental or public body or authority, or any subdivision thereof, is
required to authorize, or is required in connection with, (i) the execution,
delivery and performance of any Credit Document to which each Borrower is a
party or (ii) the legality, validity, binding effect or enforceability of any
such Credit Document.

      6.05 Litigation. There are no actions, suits or proceedings pending or, to
the best knowledge of any Borrower, threatened (i) with respect to any Credit
Document or (ii) that are reasonably likely to materially and adversely affect
the business, operations, property, assets, condition (financial or otherwise)
or (to the knowledge of such Borrower) prospects of such Borrower or of such
Borrower and its Subsidiaries taken as a whole.

      6.06 True and Complete Disclosure. All factual information (taken as a
whole) heretofore or contemporaneously furnished by or on behalf of each
Borrower in writing to any Bank (including, without limitation, all information
contained in the Credit Documents) for purposes of or in connection with this
Agreement or any transaction contemplated herein is, and all other such factual
information (taken as a whole) hereafter furnished by or on behalf of such
Borrower in writing to any Bank will be, true and accurate in all material
respects on the date as of which such information is dated or certified and does
not or will not omit to state any fact


                                      -27-

material respect at such time in light of the circumstances under which such
information was provided.

      6.07 Use of Proceeds; Margin Regulations. All proceeds of each Loan shall
be used by each Borrower for general corporate purposes, including acquisitions.
No part of the proceeds of any Loan will be used by such Borrower to purchase or
carry any Margin Stock or to extend credit to others for the purpose of
purchasing or carrying any Margin Stock in violation of Regulation T, U or X of
the Board of Governors of the Federal Reserve Board. Not more than 25% of the
value of the assets of such Borrower or such Borrower and its Subsidiaries
subject to the restrictions contained in Section 8 of this Agreement constitute
Margin Stock and, at the time of each Borrowing, not more than 25% of the value
of the assets of such Borrower or such Borrower and its Subsidiaries subject to
the restrictions contained in Section 8 of this Agreement will constitute Margin
Stock. Notwithstanding the foregoing provisions of this Section 6.07, no
Borrower will use the proceeds of any Loan to purchase the capital stock of any
corporation in a transaction, or as part of a series of transactions, (i) the
purpose of which is, at the time of any such purchase, to acquire control of
such corporation or (ii) the result of which is the ownership by the Guarantor
and its Subsidiaries (including, without limitation, such Borrower) of 10% or
more of the capital stock of such corporation, in either case if the Board of
Directors of such corporation has publicly announced its opposition to such
transaction.

      6.08 Tax Returns and Payments. Each of the Borrowers and its Subsidiaries
has filed all tax returns required to be filed (taking into account all valid
extensions) by it and has paid all income taxes payable by it which have become
due pursuant to such tax returns and all other taxes and assessments payable by
it which have become due, other than those not yet delinquent and except for
those contested in good faith and for which adequate reserves have been
established. Each Borrower and its Subsidiaries has paid, or has provided
adequate reserves (in the good faith judgment of the management of the Borrower)
for the payment of, all Federal and state income taxes or income tax imposed by
any other relevant jurisdiction applicable for all prior fiscal years and for
the current fiscal year to the end of the fiscal quarter immediately preceding
the date hereof.

      6.09 Compliance with ERISA. Each Plan is in substantial compliance with
ERISA; no Plan is insolvent or in reorganization, no Plan has an Unfunded
Current Liability, and no Plan has an accumulated or waived funding deficiency
or permitted decreases in its funding standard account within the meaning of
Section 412 of the Code; neither OFI or OCI or any Subsidiary or ERISA Affiliate
of OFI or OCI has incurred any material liability to or on account of a Plan
pursuant to Section 515, 4062, 4063, 4064, 4201 or 4204 of ERISA or expects to
incur any liability under any of the foregoing sections on account of the
termination of participation in or contributions to any such Plan; no

Subsidiaries of incurring a liability to or on account of a Plan pursuant to the
foregoing provisions of ERISA and the Code; no Lien imposed under the Code or
ERISA on the assets of OFI, OCI or any of their respective Subsidiaries exists
or is likely to arise on account of any Plan; and OFI, OCI and

benefit plans maintained by them without incurring any material liability to any
Person interested therein.

Subsidiaries is in compliance with all applicable statutes, regulations and
orders of, and all applicable restrictions imposed by, all governmental bodies,
domestic or foreign in respect of the conduct of its business and the ownership
of its property (including applicable statutes, regulations, orders and
restrictions relating to environmental standards and controls), except such
noncompliances as would not, if the aggregate, have a material adverse effect on
the business, operations, property, assets, condition (financial or otherwise)
or (to the knowledge of such Borrower) prospects of such Borrower or of such
Borrower and its Subsidiaries taken as a whole.

      Section 10. The Administrative Agent; Agents.

      10.01 Appointment. The Banks hereby designate Citibank as Administrative
Agent, to act as specified herein and in the other Credit Documents. Each Bank
hereby irrevocably authorizes, and each holder of any Note by the acceptance of
such Note shall be deemed irrevocably to authorize, the Administrative Agent to
take such action on its behalf under the provisions of this Agreement, the other
Credit Documents and any other instruments and agreements referred to herein or
therein and to exercise such powers and to perform such


                                      -35-


duties hereunder and thereunder as are specifically delegated to or required of
the Administrative Agent by the terms hereof and thereof and such other powers
as are reasonably incidental thereto. The Administrative Agent may perform any
of its duties hereunder by or through its officers, directors, agents or
employees.

      10.02 Nature of Duties. The Administrative Agent shall have no duties or
responsibilities except those expressly set forth in this Agreement and the
Guaranty. Neither the Administrative Agent nor any of its officers, directors,
agents or employees shall be liable for any action taken or omitted by it or
them hereunder or under any other Credit Document or in connection herewith or
therewith, unless caused by its or their gross negligence or willful misconduct.
The duties of the Administrative Agent shall be mechanical and administrative in
nature; the Administrative Agent shall not have by reason of this Agreement or
any other Credit Document a fiduciary relationship in respect of any Bank or the
holder of any Note; and nothing in this Agreement or any other Credit Document,
expressed or implied, is intended to or shall be so construed as to impose upon
the Administrative Agent any obligations in respect of this Agreement or any
other Credit Document except as expressly set forth herein.

      10.03 Lack of Reliance on the Administrative Agent. Independently and
without reliance upon the Administrative Agent, each Bank and the holder of each
Note, to the extent it deems appropriate, has made and shall continue to make
its own independent investigation and appraisal of the financial condition and
affairs of the Borrowers and the Guarantor in connection with the making and the
continuance of the Loans and the taking or not taking of any action in
connection herewith and, except as expressly provided in this Agreement, the
Administrative Agent shall have no duty or responsibility, either initially or
on a continuing basis, to provide any Bank or the holder of any Note with any
credit or other information with respect thereto, whether coming into its
possession before the making of the Loans or at any time or times thereafter.
The Administrative Agent shall not be responsible to any Bank or the holder of
any Note for any recitals, statements, information, representations or
warranties herein or in any document, certificate or other writing delivered in
connection herewith or for the execution, effectiveness, genuineness, validity,
enforceability, perfection, collectibility, priority or sufficiency of this
Agreement or any other Credit Document or the financial condition of the
Borrowers or the Guarantor or be required to make any inquiry concerning either
the performance or observance of any of the terms, provisions or conditions of
this Agreement or any other Credit Document, or the financial condition of the
Borrowers or the Guarantor or the existence or possible existence of any Default
or Event of Default.

      10.04 Certain Rights of the Administrative Agent. If the Administrative
Agent shall request instructions from the Required Banks with respect to any act
or action (including failure to act) in connection with this Agreement or any
other Credit Document, the Administrative Agent shall be entitled to refrain
from such act or taking such action unless and until the Administrative Agent
shall have received instructions from the Required Banks; and the Administrative
Agent shall not incur liability to any Person by reason of so refraining.
Without limiting the foregoing, no Bank or the holder of any Note shall have any
right of action whatsoever against the Administrative Agent as a result of the
Administrative Agent's acting or


                                      -36-


refraining from acting hereunder or under any other Credit Document in
accordance with the instructions of the Required Banks.

      10.05 Reliance. The Administrative Agent shall be entitled to rely, and
shall be fully protected in relying, upon any note, writing, resolution, notice,
statement, certificate, telex, teletype or telecopier message, cablegram,
radiogram, order or other document or telephone message signed, sent or made by
any Person that the Administrative Agent believed to be the proper Person, and,
with respect to all legal matters pertaining to this Agreement and any other
Credit Document and its duties hereunder and thereunder, upon advice of counsel
selected by it.

      10.06 Indemnification. To the extent the Administrative Agent is not
reimbursed by the Borrowers, the Banks will reimburse the Administrative Agent
on demand, in proportion to their respective percentages used in determining the
Required Banks at such time, for and against any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, suits,
costs, expenses (including, without limitation, attorneys' fees and expenses) or
disbursements of whatsoever kind or nature which may be imposed on, asserted
against or incurred by the Administrative Agent in performing its duties
hereunder or under any other Credit Document, or in any way relating to or
arising out of this Agreement or any other Credit Document; provided that no
Bank shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent's gross negligence or willful
misconduct. The obligations of the Banks under this Section 10.06 shall survive
the termination of this Agreement.

      10.07 The Administrative Agent in its Individual Capacity. The
Administrative Agent may accept deposits from, lend money to, and generally
engage in any kind of banking, trust or other business with the Borrowers or any
Affiliate of the Borrowers as if it were not performing the duties specified
herein, and may accept fees and other consideration from the Borrowers for
services in connection with this Agreement and otherwise without having to
account for the same to the Banks.

      10.08 Holders. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes hereof unless and until a written
notice of the assignment, transfer or endorsement thereof, as the case may be,
shall have been filed with the Administrative Agent. Any request, authority or
consent of any Person who, at the time of making such request or giving such
authority or consent, is the holder of any Note shall be conclusive and binding
on any subsequent holder, transferee, assignee or indorsee, as the case may be,
of such Note or of any Note or Notes issued in exchange therefor.

      10.09 Resignation By the Administrative Agent. (a) The Administrative
Agent may resign from the performance of all its functions and duties hereunder
and/or under the other Credit Documents at any time by giving 15 Business Days'
prior written notice to the Borrowers and the Banks. Such resignation shall take
effect upon the appointment of a successor Administrative Agent pursuant to
clauses (b) and (c) below or as otherwise provided below.


                                      -37-


      (b) Upon any such notice of resignation, the Banks shall appoint a
successor Administrative Agent hereunder or thereunder who shall be a commercial
bank or trust company reasonably acceptable to the Borrowers.

      (c) If a successor Administrative Agent shall not have been so appointed
within such 15 Business Day period, the Administrative Agent, with the consent
of the Borrowers, may then appoint a successor Administrative Agent who shall
serve as Administrative Agent hereunder or thereunder until such time, if any,
as the Banks appoint a successor Administrative Agent as provided above.

      (d) If no successor Administrative Agent has been appointed pursuant to
clause (b) or (c) above by the 20th Business Day after the date such notice of
resignation was given by the Administrative Agent, the Administrative Agent's
resignation shall become effective and the Banks shall thereafter perform all
the duties of the Administrative Agent hereunder and/or under any other Credit
Document until such time, if any, as the Banks appoint a successor
Administrative Agent as provided above.

      10.10 Lead Arranger, Documentation Agent and Syndication Agents. The Lead
Arranger, the Documentation Agent and the Syndication Agents so named on the
cover page of this Agreement shall have no rights or obligations under this
Agreement in their respective capacities as Lead Arranger, the Documentation
Agent and the Syndication Agents.

      10.11 Replacement. The Guarantor may, with the consent of the Required
Banks, replace the Bank which is acting in the capacity of Administrative Agent,
but solely with respect to such capacity.

      Section 11. Miscellaneous.

      11.01 Payment of Expenses, etc. The Borrowers shall: (i) whether or not
the transactions herein contemplated are consummated, pay all reasonable
out-of-pocket costs and expenses (x) of the Administrative Agent (including,
without limitation, the fees and disbursements of Milbank, Tweed, Hadley &
McCloy LLP) in connection with the preparation, execution and delivery of this
Agreement and the other Credit Documents and the documents and instruments
referred to herein and therein and any amendment, waiver of consent relating
hereto or thereto and (y) of the Administrative Agent and each of the Banks in
connection with the enforcement of this Agreement and the other Credit Documents
and the documents and instruments referred to herein and therein (including,
without limitation, the fees and disbursements of counsel for the Administrative
Agent and for each of the Banks); (ii) pay and hold each of the Banks harmless
from and against any and all present and future stamp and other similar taxes
with respect to the foregoing matters and save each of the Banks harmless from
and against any and all liabilities with respect to or resulting from any delay
or omission (other than to the extent attributable to such Bank) to pay such
taxes; and (iii) indemnify each of the Administrative Agent and each Bank, its
Affiliates and their respective officers, directors, employees, representatives
and agents from and hold each of them harmless against any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, suits,
costs,


                                      -38-


expenses and disbursements incurred by any of them as a result of, or arising
out of, or in any way related to, or by reason of, any investigation, litigation
or other proceeding (whether or not the Administrative Agent or any Bank is a
party thereto) related to the entering into and/or performance of this Agreement
or any other Credit Document or the use or proposed use of the proceeds of any
Loans or the consummation of any transactions contemplated herein or in any
other Credit Document, including, without limitation, the fees and disbursements
of counsel incurred in connection with any such investigation, litigation or
other proceeding (but excluding any such liabilities, obligations, losses, etc.,
to the extent incurred by reason of the gross negligence or willful misconduct
of the Person to be indemnified).

      11.02 Right of Setoff. In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, upon the occurrence of an Event of Default, each Bank and the
Administrative Agent (each, together with its Affiliates, a "Relevant
Institution") is hereby authorized at any time or from time to time, without
presentment, demand, protest or other notice of any kind to the Borrowers or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Relevant Institution (including,
without limitation, by branches and agencies of such Relevant Institution
wherever located) to or for the credit or the account of a Borrower against and
on account of the Obligations and liabilities of such Borrower to such Relevant
Institution under this Agreement or under any of the other Credit Documents,
including, without limitation, all interests in Obligations purchased by such
Relevant Institution (if a "Bank") pursuant to Section 11.06(b), and all other
claims of any nature or description arising out of or connected with this
Agreement or any other Credit Document, irrespective of whether or not such
Relevant Institution shall have made any demand hereunder and although said
Obligations, liabilities or claims, or any of them, shall be contingent or
unmatured.

      11.03 Notices. Except as otherwise expressly provided herein, all notices
and other communications provided for hereunder shall be in writing (including
telegraphic, telex, telecopier or cable communication) and mailed, telegraphed,
telexed, telecopied, cabled or delivered: if to the Borrowers, at their
respective addresses specified opposite their signatures below; if to any Bank,
at its address (or telecopy number) set forth in its Administrative
Questionnaire; if to the Administrative Agent, at its Notice Office; or, as to
the Borrowers or the Administrative Agent, at such other address as shall be
designated by such party in a written notice to the other parties hereto and, as
to each other party, at such other address as shall be designated by such party
in a written notice to the Borrowers and the Administrative Agent. All such
notices and communications shall, when mailed, telegraphed, telexed, telecopied,
or cabled or sent by overnight courier, be effective when deposited in the
mails, delivered to the telegraph company, cable company or overnight courier,
as the case may be, or sent by telex or telecopier, except that notices and
communications to the Administrative Agent and notices and communications sent
by mail to any party, shall not be effective until received.

      11.04 Benefit of Agreement. (a) This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties


                                      -39-


hereto; provided, however, that the Borrowers may not assign or transfer any of
their respective rights or obligations hereunder without the prior written
consent of the Banks; and provided, further, that, although any Bank may
transfer, assign or grant participations in its rights hereunder and under the
Notes, such Bank shall remain a "Bank" for all purposes hereunder (and may not
transfer or assign its Commitment hereunder except as provided in Section
11.04(b)) and the transferee, assignee or participant, as the case may be, shall
not constitute a "Bank" hereunder; and provided, further, that no Bank shall
transfer, grant or assign any participation under which the participant shall
have rights to approve any amendment to or waiver of this Agreement except to
the extent such amendment or waiver requires the consent of 100% of the Banks,
as provided in Section 11.12. In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Credit Documents (the participant's rights against such Bank in respect of such
participation to be those set forth in the agreement executed by such Bank in
favor of the participant relating thereto) and all amounts payable by the
Borrowers hereunder shall be determined as if such Bank had not sold such
participation, except that the participant shall be entitled to the benefits of
Sections 2.10, 2.11 and 4.03 of this Agreement to the extent that such Bank
would be entitled to such benefits if the participation had not been
transferred, granted or assigned. Promptly following the consummation of any
participation pursuant to this Section 11.04(a), the Bank entering into such
participation shall promptly notify the Borrowers thereof.

      (b) Notwithstanding the foregoing, any Bank may, with prior written
consent of the Guarantor (whose consent shall not be unreasonably withheld),
assign all, or if less than all, a portion equal to at least $5,000,000 in the
aggregate of its Commitment (and related outstanding principal amount of Loans)
hereunder to one or more commercial banks or other financial institutions
engaged in the business of lending money or acquiring debt securities; provided
that (i) at such time Schedule I hereto shall be deemed modified to reflect the
Commitments of such new Bank and of the existing Banks, (ii) upon surrender of
the old Notes, if any, or, upon presentation of evidence to the reasonable
satisfaction of the Administrative Agent (in the Administrative Agent's sole
discretion) of the loss, destruction or theft of such old Notes, and upon
delivery to the Administrative Agent, for the benefit of the Borrower that
issued the old Notes, of an indemnity, in form and substance satisfactory to
such Borrower, made by such assigning Bank and holding such Borrower harmless,
in lieu of any such lost, destroyed or stolen Notes, new Notes will be issued,
at the expense of the Borrower that issued the old Notes, to such new Bank and
to the assigning Bank, such new Notes to be in conformity with the requirements
of Section 2.05 (with appropriate modifications) to the extent needed to reflect
the revised Commitments, (iii) the Administrative Agent shall receive at the
time of each such assignment, from the assigning or the assignee Bank, the
payment of a non-refundable assignment fee of $3,000 and (iv) such new Bank
shall deliver to the Administrative Agent an Administrative Questionnaire. To
the extent of any assignment pursuant to this Section 11.04(b), the assigning
Bank shall be relieved of its obligations hereunder with respect to its assigned
Commitments. To the extent that an assignment of all or any portion of a Bank's
Commitments and related outstanding Obligations pursuant to this Section
11.04(b) would, at the time of such assignment, result in increased costs under
Section 2.10, 2.11 or 4.03 greater than those being charged by the respective
assigning Bank prior to such assignment, then the Borrowers shall not


                                      -40-


be obligated to pay such greater increased costs (although the Borrowers shall
be obligated to pay any other increased costs of the type described above
resulting from changes after the date of the respective assignments).

      (c) Notwithstanding anything to the contrary contained herein, each Bank
shall be entitled to pledge its Loans and/or Notes hereunder to a Federal
Reserve Bank in support of borrowings made by such Bank from such Federal
Reserve Bank.

      (d) Notwithstanding anything to the contrary contained herein, subject to
the prior written consent of the Guarantor (which shall not be unreasonably
withheld), any Bank (a "Granting Bank"), may grant to a special purpose funding
vehicle (an "SPC"), identified as such in writing from time to time by the
Granting Bank to the Administrative Agent, the Guarantor and the Borrowers, the
option to provide to the Borrowers all or any part of any Loan that such
Granting Bank would otherwise be obligated to make to the Borrower pursuant to
this Agreement; provided that (i) nothing herein shall constitute a commitment
by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such
option or otherwise fails or is unable to provide all or any part of such Loan,
the Granting Bank shall be obligated to make such Loan pursuant to the terms
hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of
the Granting Bank to the same extent, and as if, such Loan were made by such
Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for
any indemnity or payment under this Agreement for which a Bank would otherwise
be liable for so long as, and to the extent, the Granting Bank provides such
indemnity or makes such payment. In furtherance of the foregoing, each Borrower
and the Guarantor hereby agree (which agreement shall survive the termination of
this Agreement) that, prior to the date that is one year and one day after the
payment in full of all outstanding commercial paper or other senior indebtedness
of any SPC, it will not institute against, or join any other Person in
instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings under the laws of the United States or any
State thereof.

      11.05 No Waiver; Remedies Cumulative. No failure or delay on the part of
the Administrative Agent or any Bank or the holder of any Note in exercising any
right, power or privilege hereunder under any other Credit Document and no
course of dealing between the Borrowers, the Administrative Agent or any Bank or
the holder of any Note shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, power or privilege hereunder or under any
other Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder. The
rights, powers and remedies herein or in any other Credit Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies
which the Administrative Agent or any Bank or the holder of any Note would
otherwise have. No notice to or demand on the Borrowers in any case shall
entitle the Borrowers to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of the Administrative
Agent or any Bank or the holder of any Note to any other or further action in
any circumstances without notice or demand.


                                      -41-


      11.06 Payments Pro Rata. (a) The Administrative Agent agrees that promptly
after its receipt of each payment from or on behalf of any Borrower in respect
of any Obligations of such Borrower hereunder, it shall distribute such payment
to the Banks pro rata based upon their respective shares, if any, of the
Obligations with respect to which such payment was received.

      (b) Each of the Banks agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise), which is applicable to the payment of the principal of, or interest
on, the Loans, Facility Fees or other Fees, of a sum which with respect to the
related sum or sums received by other Banks is in a greater proportion than the
total amount of such Obligation then owed and due to such Bank bears to the
total amount of such Obligation then owed and due to all of the Banks
immediately prior to such receipt, then such Bank receiving such excess payment
shall purchase for cash without recourse or warranty from the other Banks an
interest in the Obligations of the Borrowers to such Banks in such amount as
shall result in a proportional participation by all the Banks in such amount;
provided, however, that if all or any portion of such excess amount is
thereafter recovered from such Bank, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest;
and provided, further, that a Bank's obligations pursuant to this Section
11.06(b) shall not be interpreted to apply to any portion of the Fee which is
payable to such Bank pursuant to Section 3.01(b) hereof and is not payable to
other Banks because of the Banks' differing Commitment levels.

      11.07 Calculations; Computations. All computations of interest and
Facility Fees hereunder shall be made on the basis of a year of 360 days
(365/366 days in the case of interest on Base Rate Loans) for the actual number
of days (including the first day but excluding the last day) occurring in the
period for which such interest or Facility Fees are payable. Notwithstanding the
foregoing, for each day that interest is calculated by reference to the Federal
Funds Rate, such interest shall be computed on the basis of a year of 360 days.

      11.08 Governing Law; Submission to Jurisdiction; Venue. (a) This Agreement
and the other Credit Documents and the rights and obligations of the parties
hereunder and thereunder shall be construed in accordance with and be governed
by the law of the State of New York. Any legal action or proceeding against the
Borrowers with respect to this Agreement or any other Credit Document may be
brought in the courts of the State of New York or of the United States for the
Southern District of New York, and, by execution and delivery of this Agreement,
each Borrower hereby irrevocably accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts. Each Borrower agrees that if at any time its principal place of business
is not in the City and State of New York, it will irrevocably designate, appoint
and empower an agent for purposes of this Section, in the City and State of New
York, as its designee, appointee and agent to receive, accept and acknowledge
for and on its behalf, and in respect of its property, service of any and all
legal process, summons, notices and documents which may be served in any such
action or proceeding. If for


                                      -42-


any reason such designee, appointee and agent shall cease to be available to act
as such, each Borrower agrees to designate a new designee, appointee and agent
in New York City on the terms and for the purposes of this provision
satisfactory to the Administrative Agent. Each Borrower further irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to such Borrower at its address set forth
opposite its signature below, such service to become effective 30 days after
such mailing. Nothing herein shall affect the right of the Administrative Agent,
any Bank or the holder of any Note to serve process in any other manner
permitted by law or to commence legal proceedings or otherwise proceed against
the Borrowers in any other jurisdiction.

      (b) Each Borrower hereby irrevocably waives any objection which it may now
or hereafter have to the laying of venue of any of the aforesaid actions or
proceedings arising out of or in connection with this Agreement or any other
Credit Document brought in the courts referred to in clause (a) above and hereby
further irrevocably waives and agrees not to plead or claim in any such court
that any such action or proceeding brought in any such court has been brought in
an inconvenient forum.

      11.09 Payment Denominations. All payments of principal and interest on any
Loan and other amounts to be paid by any Borrower under this Agreement shall be
made in Dollars. The obligation of the Borrowers to make payment in Dollars of
the principal of and interest on the Notes and any other amounts due hereunder
or under any other Credit Document to the Payment Office of the Administrative
Agent as provided in Section 4.02 shall not be discharged or satisfied by any
tender, or any recovery pursuant to any judgment, which is expressed in or
converted into any currency other than Dollars, except to the extent such tender
or recovery shall result in the actual receipt by the Administrative Agent at
its Payment Office on behalf of the Banks or holders of the Notes of the full
amount of Dollars expressed to be payable in respect of the principal of and
interest on the Notes and all other amounts due hereunder or under any other
Credit Document. The obligation of the Borrowers to make payments in Dollars as
aforesaid shall be enforceable as an alternative or additional cause of action
for the purpose of recovery in Dollars of the amount, if any, by which such
actual receipt shall fall short of the full amount of Dollars expressed to be
payable in respect of the principal of and interest on the Notes and any other
amounts due under any other Credit Document, and shall not be affected by
judgment being obtained for any other sums due under this Agreement or under any
other Credit Document.

      11.10 Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A set of counterparts
executed by all the parties hereto shall be lodged with the Borrowers and the
Administrative Agent.


                                      -43-


      11.11 Headings Descriptive. The headings of the several sections and
subsections of this Agreement are inserted for convenience only and shall not in
any way affect the meaning or construction of any provision of this Agreement.

      11.12 Amendment or Waiver. None of this Agreement or any other Credit
Document nor any terms hereof or thereof may be changed, waived, discharged or
terminated unless such change, waiver, discharge or termination is in writing
signed by the Required Banks; provided, however, that: no such change, waiver,
discharge or termination shall, without the consent of each Bank, (i) extend the
Commitment Termination Date (except as provided in Section 3.03) or the final
maturity of any Loan or Note or reduce the rate or extend the time of payment of
interest or Fees thereon, or reduce the principal amount thereof, or increase
the Commitment of any Bank (except as provided in Section 3.04) over the amount
thereof then in effect (it being understood that a waiver of any Default or
Event of Default or of a mandatory reduction in the Total Commitment shall not
constitute a change in the terms of any Commitment of any Bank), (ii) release
the Guarantor from its obligations under the Guaranty, (iii) amend, modify or
waive any provision of this Section 11.12 or Section 10.06, 11.01, 11.02, 11.04,
11.06 or 11.07, (iv) reduce the percentage specified in the definition of
Required Banks, or (v) consent to the assignment or transfer by the Borrowers of
any of their rights and obligations under this Agreement.

      11.13 Survival. All indemnities set forth herein, including, without
limitation, in Sections 2.10, 2.11, 4.03, 10.06 and 11.01, shall survive the
execution and delivery of this Agreement and the Notes and the making and
repayment of the Loans.

      11.14 Domicile of Loans. Subject to Section 4.03(b), but notwithstanding
Section 11.04 (b), each Bank may transfer and carry its Loans at, to or for the
account of any office, Subsidiary or Affiliate of such Bank; provided, that each
Bank will use its best efforts not to effect a transfer of its Loans to an
Applicable Lending Office which would give rise to the operation of Section
2.10(a) (ii) or (iii) or 2.10(c) unless in its sole discretion such Bank finds
that such nontransfer would be disadvantageous to it.

      11.15 Limitation on Additional Amounts, etc. Notwithstanding anything to
the contrary contained in Sections 2.10, 2.11 or 4.03 of this Agreement, (a) a
Bank shall not be entitled to payment of any amount under any such Section from
a Borrower unless such Bank is seeking payment from other borrowers similarly
situated in respect of the relevant increased costs, Taxes, losses, expenses or
liabilities, reduction in amounts received or receivable or reduction in return
on capital, and (b) unless a Bank gives notice to the Borrowers that they are
obligated to pay an amount under any such Section within six months after the
later of (x) the date such Bank incurs the respective increased costs, Taxes,
loss, expense or liability, reduction in amounts received or receivable or
reduction in return on capital or (y) the date such Bank has actual knowledge of
its incurrence of the respective increased costs, Taxes, loss, expense or
liability, reductions in amounts received or receivable or reduction in return
on capital, then such Bank shall only be entitled to be compensated for such
amount by the Borrowers pursuant to said Section 2.10, 2.11 or 4.03, as the case
may be, to the extent the costs, Taxes, loss, expense or


                                      -44-


liability, reduction in amounts received or receivable or reduction in return on
capital are incurred or suffered on or after the date which occurs six months
prior to such Bank's notice to the Borrowers that it is obligated to pay the
respective amounts pursuant to said Section 2.10, 2.11 or 4.03, as the case may
be. This Section 11.15 shall have no applicability to any Section of this
Agreement other than said Sections 2.10, 2.11 and 4.03.


                                      -45-

                                                                          [Date]

To the Persons Listed on
Annex I Hereto

Ladies and Gentlemen:

      We have acted as special New York counsel for Omnicom Finance Inc., a
corporation organized and existing under the laws of the State of Delaware
("OFI"), Omnicom Capital Inc., a corporation organized and existing under the
laws of the State of Connecticut ("OCI"), Omnicom Finance Plc, a company
organized and existing under the laws of England and Wales ("OFP" and together
with OFI and OCI, individually, a "Borrower" and collectively, the "Borrowers")
and Omnicom Group Inc., a corporation organized and existing under the laws of
the State of New York (the "Guarantor"), in connection with the execution and
delivery of the following documents (collectively, the "Credit Documents"):

            (a) the 364-Day Credit Agreement, dated as of April 25, 2002, among
      the Borrowers, the banks parties thereto (the "Banks") and Citibank, NA.,
      as the Administrative Agent (the "Credit Agreement");

            (b) the Notes of OFI and OCI (if any), to be delivered pursuant to
      the Credit Agreement; and

            (c) the Guaranty of the Guarantor, dated as of April 25, 2002,
      delivered pursuant to Section 5.01(d) of the Credit Agreement (the
      "Guaranty").

      This opinion is delivered to you pursuant to Section 5.01(b) of the Credit
Agreement. Terms used herein which are defined in the Credit Agreement shall
have the respective meanings set forth in the Credit Agreement, unless otherwise
defined herein.

      In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of each of the Credit
Documents. In addition, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such records, instruments and other
documents, and have made such other investigations, as we have deemed relevant
and necessary as a basis for the opinions hereinafter set forth.

      For the purposes hereof, we have assumed, with your permission and without
independent verification of any kind: (a) that the signatures of persons (other
than OFI, OCI and the Guarantor) signing all documents in connection with which
this opinion is rendered are genuine and authorized; (b) the legal capacity of
all natural persons; (c) that all documents submitted to us as originals or
duplicate originals are authentic; and (d) that all documents submitted to us as
copies, whether certified or not, conform to authentic original documents. As to
questions of fact relevant to this opinion, we have assumed, without independent
investigation or verification of any kind, the accuracy of




                                                                     EXHIBIT C-1
                                                                          Page 2

the representations and warranties of the Borrowers and the Guarantor in the
applicable Credit Documents and have relied upon certificates and oral or
written statements and other information of public officials, and officers and
representatives of the Borrowers and the Guarantor. For purposes of the opinion
set forth in the paragraph numbered 1 below, we have relied solely upon copies
of (i) certificates of, and (ii) the organizational documents as certified by,
public officials as of the dates and in the jurisdictions listed on Annex II
hereto.

      In rendering the opinions expressed below, we have assumed, with your
permission and without any independent investigation or verification of any
kind, that: (i) each party to the Credit Documents other than OFI, OCI and the
Guarantor (individually, the "Other Party" and collectively, the "Other
Parties") has been duly organized and is validly existing and in good standing
under the laws of its jurisdiction of incorporation and is duly qualified in
each other jurisdiction in which the conduct of its business or the ownership of
its property makes such qualification necessary; (ii) each of the Other Parties
has full power and authority to execute, deliver and perform the Credit
Documents to which it is a party; (iii) the execution, delivery and performance
of the Credit Documents by each of the Other Parties have been duly authorized
by all requisite corporate action on the part of each Other Party; (iv) the
Credit Documents have been duly executed and delivered by each of the Other
Parties; and (v) the execution, delivery and performance of the Credit Documents
by each of the Other Parties do not and will not violate the charter, by-laws or
other organizational documents of any of the Other Parties. We have further
assumed, with your permission and without any independent investigation or
verification of any kind, that each of the Credit Documents constitutes the
valid and legally binding obligations of each Other Party, enforceable against
such Other Party in accordance with its terms. Furthermore, in giving the
opinions set forth in paragraphs numbered 3 and 4 below, we express no opinion
as to state securities or blue sky laws.

      Based upon the foregoing, and subject to the limitations set forth herein,
we are of the opinion that:

      1. Each of the Guarantor, OFI, OCI and the other designated subsidiaries
of the Guarantor listed on Annex III hereto (the "Designated Subsidiaries") (i)
is a duly organized and validly existing corporation in good standing under the
laws of the jurisdiction of its incorporation listed on Annex II hereto and (ii)
has the power and authority to own its property and assets and to transact the
business in which it is engaged.

      2. Each of OFI, OCI and the Guarantor has the corporate power to execute,
deliver and perform the terms and provisions of each of the Credit Documents to
which it is a party and has taken all necessary corporate action to authorize
the execution, delivery and performance by it of each of such Credit Documents.
Each of OFI, OCI and the Guarantor has duly executed and delivered each of the
Credit Documents to which it is a party. Each of the Credit Documents to which
the Guarantor, OFI or OCI is a party constitutes its legal, valid and binding
obligation enforceable against it in accordance with the terms of such Credit
Document.

      3. Neither the execution, delivery nor performance by OFI, OCI or the
Guarantor of the Credit Documents to which it is a party, nor compliance by it
with the terms and provisions thereof, (i) will contravene any provision of any
law, statute,




                                                                     EXHIBIT C-1
                                                                          Page 3

rule or regulation (including, without limitation, Regulation T, U or X of the
Board of Governors of the Federal Reserve System) of the United States of
America or the State of New York applicable to OFI, OCI or the Guarantor or (ii)
will violate any provision of the Certificate of Incorporation or By-Laws of
OFI, OCI or the Guarantor.

      4. No order, consent, approval, license, authorization or validation of,
or filing, recording or registration with (except as have been obtained or made
on or prior to the date hereof), or exemption by, any governmental or public
body or authority of the United States of America, or the State of New York,
applicable to OFI, OCI or the Guarantor is required to authorize, or is required
in connection with, (i) the execution, delivery and performance by OFI, OCI or
the Guarantor, respectively, of any Credit Document to which OFI, OCI or the
Guarantor is a party or (ii) the enforceability of any such Credit Document in
accordance with its terms against OFI, OCI or the Guarantor.

      5. None of the Guarantor, OFI or OCI is an "investment company" within the
meaning of the Investment Company Act of 1940, as amended.

      6. None of the Guarantor, OFI or OCI is a "holding company," or a
"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company" within the meaning
of the Public Utility Holding Company Act of 1935, as amended.

      7. The choice of New York law as the governing law of each of the Credit
Documents is, under the laws of the State of New York, a valid choice of law.

      8. The consent by OFI and OCI in Section 11.08 of the Credit Agreement,
and by the Guarantor in paragraph 18 of the Guaranty, to the jurisdiction of
courts sitting in the State of New York is a valid consent to the jurisdiction
of such courts.

      Our opinions are subject to the qualifications that:

      A. The enforceability of the Credit Documents is subject to and may be
limited by bankruptcy, insolvency, reorganization, fraudulent conveyance,
moratorium, or other similar laws relating to or affecting the rights of
creditors generally (including such as may deny giving effect to waivers of
debtors' or guarantors' rights), and the application of general principles of
equity (regardless of whether considered in a proceeding in equity or at law),
including, without limitation, (i) the possible unavailability of specific
performance, injunctive relief or any other equitable remedy and (ii) concepts
of materiality, reasonableness, good faith and fair dealing. Accordingly, no
opinion is given herein as to (i) the availability of the right to accelerate
any obligation and certain remedies provided for in the Credit Documents in the
event of a nonmaterial default or (ii) the enforceability of any provision of
the Credit Documents relating to cumulation of remedies or waiving the remedy of
specific performance.

      B. We express no opinion as to the enforceability of any contractual
provision in the Credit Documents as to waiver of any procedural right,
including, without limitation, (i) the waiver of setoff, counterclaim or other
defense in Section 4.03(a) of the Credit Agreement and in the final sentence of
paragraph 1 of the Guaranty, (ii) the second sentence of Section 11.08 (a) of
the Credit Agreement and the second sentence of paragraph 18 of the Guaranty,
insofar as such sentences relate to the subject matter jurisdiction of the
United States District Court for the Southern District of New




                                                                     EXHIBIT C-1
                                                                          Page 4

York to adjudicate any controversy related to any of the Credit Documents, and
(iii) the waiver of inconvenient forum set forth in Section 11.08(b) of the
Credit Agreement and paragraph 18 of the Guaranty with respect to proceedings in
the United States District Court for the Southern District of New York.

      C. We express no opinion as to the enforceability of any contractual
provision in the Credit Documents relating to indemnification, including,
without limitation, with respect to the enforceability of Section 11.01 of the
Credit Agreement (and any similar provisions in any of the other Credit
Documents), to the extent that these may be limited (i) in the case of
litigation against OFI, OCI or the Guarantor which is decided adversely to the
person claiming indemnification or in a case involving a claim of
indemnification for attorneys' fees; (ii) by laws rendering unenforceable
indemnification contrary to federal or state securities laws and the public
policy underlying such laws; and (iii) by laws limiting the enforceability of
provisions exculpating or exempting a party, or requiring indemnification of a
party, for liability for its own action or inaction, to the extent the action or
inaction involves gross negligence, recklessness, willful misconduct or unlawful
conduct.

      D. Furthermore, no opinion is given herein as to:

            (i) the enforceability of any right or obligation to the extent that
      the same has been varied by course of dealing or performance; or

            (ii) paragraph 3(a) of the Guaranty, and clause (b) of paragraph 4
      of the Guaranty to the extent that it relates to action contemplated by
      paragraph 3(a) of the Guaranty, which may not be enforceable to the extent
      that the Guaranteed Obligations are materially altered; or

            (iii) the enforceability of provisions in the Credit Documents to
      the effect that terms may not be waived or modified except in writing,
      which may be limited under certain circumstances; or

            (iv) the effect of the laws of any jurisdiction in which any Bank is
      located (other than the State of New York) that limit the interest, fees
      or other charges such Bank may impose; or

            (v) the enforceability of the provisions of Section 11.09 of the
      Credit Agreement or paragraph 19 of the Guaranty (A) to the extent that a
      judgment not in Dollars is obtained in respect of the Credit Agreement in
      a jurisdiction other than the United States of America and the respective
      Borrower or the Guarantor pays such judgment or (B) insofar as those
      provisions contemplate an alternative or additional cause of action for a
      claim that may have merged with claims covered by an earlier judgment; or

            (vi) paragraph 16 of the Guaranty; or

            (vii) the enforceability of the right of setoff provided for in
      Section 11.02 of the Credit Agreement (A) in respect of an interest in
      Obligations purchased by a Bank pursuant to Section 11.06(b), to the
      extent the relevant purchase does not give rise to a direct obligation of
      OFI or OCI to such Bank, or (B) insofar as that right relates to setoff of
      unmatured Obligations or of




                                                                     EXHIBIT C-1
                                                                          Page 5

      obligations owed to the Guarantor by Affiliates of the Banks or by
      Affiliates of the Administrative Agent.

      We are members of the Bar of the State of New York and express no opinion
as to the laws of any jurisdiction other than those of the laws of the State of
New York, the General Corporation Law of the State of Delaware and the federal
laws of the United States of America.

      This opinion is rendered solely to the persons listed on Annex I hereto by
us as special counsel to OFI, OCI and the Guarantor in connection with the
transactions contemplated by the Credit Documents. This opinion may not be
relied upon in any manner or for any purpose, or furnished or relied upon by any
other person, without our prior written consent. The information set forth
herein is as of the date of this letter, and we disclaim any undertaking to
advise the persons listed on Annex I hereto of changes which thereafter may be
brought to our attention.

                                                                     EXHIBIT C-1

                  FORM OF OPINION OF COUNSEL (NEW YORK) - BANKS

                                                                          [Date]

To the Banks party to the
Credit Agreement referred to
below and Citibank, N.A.,
as Administrative Agent

Ladies and Gentlemen:

      We have acted as special New York counsel to Citibank, N.A. ("Citibank")
in connection with (i) the 364-Day Credit Agreement, dated as of April 25, 2002,
among Omnicom Finance Inc. ("OFI"), Omnicom Capital Inc. ("OCI"), Omnicom
Finance Plc ("OFP" and, together with OFI and OCI, individually, a "Borrower"
and collectively, the "Borrowers"), the financial institutions named therein
(the "Banks") and Citibank, as Administrative Agent, and (ii) the various other
agreements, instruments and other documents referred to in the next following
paragraph. Except as otherwise provided herein, terms defined in the Credit
Agreement are used herein as defined therein. This opinion letter is being
delivered pursuant to Section 5.01(b) of the Credit Agreement.

      In rendering the opinions expressed below, we have examined the following
agreements and instruments (the "Financing Documents"):

      (a)   the Credit Agreement;

      (b)   the Notes executed and delivered pursuant to the Credit Agreement on
            the date hereof; and

      (c)   the Guaranty of Omnicom Group Inc. (the "Guarantor" and, together
            with the Borrowers, the "Obligors"), dated as of April 25, 2002,
            delivered pursuant to Section 5.01(d) of the Credit Agreement (the
            "Guaranty").

In addition, we have assumed that the making and performance and the
consummation of the transactions contemplated by the Financing Documents by OFP
do not violate, and the Financing Documents to which OFP is a party are not
unenforceable under, the laws or public policy of England.

      In rendering the opinions expressed below, we have assumed, with respect
to all of the documents referred to in this opinion letter, that:

      (i)   such documents have been duly authorized by, have been duly executed
            and delivered by, and (except to the extent set forth in the
            opinions below as to the Obligors) constitute legal, valid, binding
            and enforceable obligations of, all of the parties to such
            documents;

      (ii)  all signatories to such documents have been duly authorized; and




                                                                     EXHIBIT C-2
                                                                          Page 2

      (iii) all of the parties to such documents are duly organized and validly
            existing and have the power and authority (corporate or other) to
            execute, deliver and perform such documents.

      Based upon and subject to the foregoing and subject also to the comments
and qualifications set forth below, and having considered such questions of law
as we have deemed necessary as a basis for the opinions expressed below, we are
of the opinion that each of the Financing Documents constitutes the legal, valid
and binding obligation of each Obligor stated to be a party thereto, enforceable
against such Obligor in accordance with its terms, except as may be limited by
bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium or other similar laws relating to or affecting the rights of
creditors generally (and by the possible judicial application of English laws or
governmental action affecting the rights of creditors generally to the
obligations of OFP) and except as the enforceability of the Financing Documents
is subject to the application of general principles of equity (regardless of
whether considered in a proceeding in equity or at law), including, without
limitation, (a) the possible unavailability of specific performance, injunctive
relief or any other equitable remedy and (b) concepts of materiality,
reasonableness, good faith and fair dealing.

      The foregoing opinion is subject to the following comments and
qualifications:

            (A) The enforceability of Section 11.01 of the Credit Agreement (and
      any similar provisions in any of the other Financing Documents) may be
      limited by (i) laws rendering unenforceable indemnification contrary to
      federal or state securities laws and the public policy underlying such
      laws and (ii) laws limiting the enforceability of provisions exculpating
      or exempting a party, or requiring indemnification of a party for,
      liability for its own action or inaction, to the extent the action or
      inaction involves gross negligence, recklessness, willful misconduct or
      unlawful conduct.

            (B) Paragraph 3(a) of the Guaranty, and clause (b) of paragraph 4 of
      the Guaranty to the extent that it relates to action contemplated by
      paragraph 3(a) of the Guaranty, may not be enforceable to the extent that
      the Guaranteed Obligations are materially altered.

            (C) The enforceability of provisions in the Financing Documents to
      the effect that terms may not be waived or modified except in writing may
      be limited under certain circumstances.

            (D) We express no opinion as to (i) the effect of the laws of any
      jurisdiction in which any Bank is located (other than the State of New
      York) that limit the interest, fees or other charges such Bank may impose,
      (ii) the second sentence of Section 11.08(a) of the Credit Agreement and
      the second sentence of paragraph 18 of the Guaranty, insofar as such
      sentences relate to the subject matter jurisdiction of the United States
      District Court for the Southern District of New York to adjudicate any
      controversy related to any of the Financing Documents, (iii) the waiver of
      inconvenient forum set forth in Section 11.08(b) of the Credit Agreement
      and paragraph 18 of the Guaranty with respect to proceedings in the United
      States District Court for the Southern District of New




                                                                     EXHIBIT C-2
                                                                          Page 3

      York, (iv) the last sentence of Section 11.09 of the Credit Agreement and
      the last sentence of paragraph 19 of the Guaranty or (v) paragraph 16 of
      the Guaranty.

      The foregoing opinions are limited to matters involving the federal laws
of the United States of America and the law of the State of New York, and we do
not express any opinion as to the laws of any other jurisdiction.

      At the request of our client, this opinion letter is, pursuant to Section
5.01(b) of the Credit Agreement, provided to you by us in our capacity as
special New York counsel to Citibank and may not be relied upon by any Person
for any purpose other than in connection with the transactions contemplated by
the Credit Agreement without, in each instance, our prior written consent.

                                                     Very truly yours,



                                                                     EXHIBIT C-3

                                                                          [Date]

To the Persons Listed on
Annex I Hereto

Ladies and Gentlemen:

      We have acted as special New York counsel for Omnicom Finance Plc, a
company organized and existing under the laws of England and Wales ("OFP"), in
connection with the execution and delivery of the following documents
(collectively, the "Credit Documents"):

            (a) the 364-Day Credit Agreement, dated as of April 25, 2002, among
      Omnicom Finance Inc., a corporation organized and existing under the laws
      of the State of Delaware, Omnicom Capital Inc., a corporation organized
      under the laws of the State of Connecticut, and OFP, as the Borrowers, the
      banks parties thereto (the "Banks") and Citibank, N.A., as the
      Administrative Agent (the "Credit Agreement"); and

            (b) the Notes of OFP (if any), to be delivered pursuant to the
      Credit Agreement.

      This opinion is delivered to you pursuant to Section 5.01(b) of the Credit
Agreement. Terms used herein which are defined in the Credit Agreement shall
have the respective meanings set forth in the Credit Agreement, unless otherwise
defined herein.

      In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of each of the Credit
Documents. In addition, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such records, instruments and other
documents, and have made such other investigations, as we have deemed relevant
and necessary as a basis for the opinions hereinafter set forth.

      For the purposes hereof, we have assumed, with your permission and without
independent verification of any kind; (a) that the signatures of persons (other
than OFP) signing all documents in connection with which this opinion is
rendered are genuine and authorized; (b) the legal capacity of all natural
persons; (c) that all documents submitted to us as originals or duplicate
originals are authentic; and (d) that all documents submitted to us as copies,
whether certified or not, conform to authentic original documents. As to
questions of fact relevant to this opinion, we have assumed, without independent
investigation or verification of any kind, the accuracy of the representations
and warranties of the Borrowers and the Guarantor in the applicable Credit
Documents and have relied upon certificates and oral or written statements and
other information of public officials, and officers and representatives of the
Borrowers and the Guarantor.




                                                                     EXHIBIT C-3
                                                                          Page 2

      In rendering the opinions expressed below, we have assumed, with your
permission and without any independent investigation or verification of any
kind, that: (i) each party to the Credit Documents other than OFP (individually,
the "Other Party" and collectively, the "Other Parties") has been duly organized
and is validly existing and in good standing under the laws of its jurisdiction
of incorporation and is duly qualified in each other jurisdiction in which the
conduct of its business or the ownership of its property makes such
qualification necessary; (ii) each of the Other Parties has full power and
authority to execute, deliver and perform the Credit Documents to which it is a
party; (iii) the execution, delivery and performance of the Credit Documents by
each of the Other Parties has been duly authorized by all requisite corporate
action on the part of each Other Party; (iv) the Credit Documents have been duly
executed and delivered by each of the Other Parties; and (v) the execution,
delivery and performance of the Credit Documents by each of the Other Parties
does not and will not violate the charter, by-laws or other organizational
documents of any of the Other Parties. We have further assumed, with your
permission and without any independent investigation or verification of any
kind, that each of the Credit Documents constitutes the valid and legally
binding obligations of each Other Party, enforceable against such Other Party in
accordance with its terms. Furthermore, in giving the opinions set forth in
paragraphs numbered 2 and 3 below, we express no opinion as to state securities
or blue sky laws.

      Based upon the foregoing, and subject to the limitations set forth herein,
we are of the opinion that:

      1. Each of the Credit Documents to which OFP is a party constitutes its
legal, valid and binding obligation enforceable against OFP in accordance with
the terms of such Credit Document.

      2. Neither the execution, delivery or performance by OFP of the Credit
Documents to which it is a party, nor compliance by it with the terms and
provisions thereof, will contravene any provision of any law, statute, rule or
regulation applicable to OFP (including, without limitation, Regulation T, U and
X of the Board of Governors of the Federal Reserve System) of the United States
of America or the State of New York.

      3. No order, consent, approval, license, authorization or validation of,
or filing, recording or registration with (except as have been obtained or made
on or prior to the date hereof), or exemption by, any governmental or public
body or authority of the United States of America or the State of New York
applicable to OFP, is required to authorize, or is required in connection with,
(i) the execution, delivery and performance by OFP of any Credit Document to
which OFP is a party or (ii) the enforceability of any such Credit Document in
accordance with its terms against OFP.

      4. The choice of New York law as the governing law of each of the Credit
Documents is, under the laws of the State of New York, a valid choice of law.

      5. The consent by OFP in Section 11.08 of the Credit Agreement to the
jurisdiction of courts sitting in the State of New York is a valid consent to
the jurisdiction of such courts, except that we express no opinion as to the
enforceability of any consent to jurisdiction insofar as such consent relates to
the subject matter jurisdiction of the United States Court for the Southern
District of New York to adjudicate any controversy related to the Credit
Documents.



                                                                     EXHIBIT C-3
                                                                          Page 3

      Our opinions are subject to the qualifications that:

      A. The enforceability of the Credit Documents is subject to and may be
limited by bankruptcy, insolvency, reorganization, fraudulent conveyance,
moratorium or other similar laws relating to or affecting the rights of
creditors generally (and by possible judicial application of English or other
foreign laws or governmental action affecting the rights of creditors generally
to the obligations of OFP), and the application of general principles of equity
(regardless of whether considered in a proceeding in equity or at law),
including, without limitation, (i) the possible unavailability of specific
performance, injunctive relief or any other equitable remedy and (ii) concepts
of materiality, reasonableness, good faith and fair dealing. Accordingly, no
opinion is given herein as to (i) the availability of the right to accelerate
any obligation and certain remedies provided for in the Credit Documents in the
event of a nonmaterial default, or (ii) the enforceability of any provision of
the Credit Documents relating to cumulation of remedies or waiving the remedy of
specific performance, or the waiver of debtors rights.

      B. We express no opinion as to the enforceability of any contractual
provision in the Credit Documents as to waiver of any procedural right,
including, without limitation, (i) the waiver of setoff, counterclaim or other
defense in Section 4.03(a) of the Credit Agreement, (ii) the second sentence of
Section 11.08(a) of the Credit Agreement, insofar as such sentence relates to
the subject matter jurisdiction of the United States District Court for the
Southern District of New York to adjudicate any controversy related to any of
the Credit Documents, and (iii) the waiver of inconvenient forum set forth in
Section 11.08(b) of the Credit Agreement with respect to proceedings in the
United States District Court for the Southern District of New York.

      C. We express no opinion as to the enforceability of any contractual
provision in the Credit Documents relating to indemnification, including,
without limitation, with respect to the enforceability of Section 11.01 of the
Credit Agreement (and any similar provisions in any of the other Credit
Documents) to the extent that these may be limited (i) in the case of litigation
against OFP which is decided adversely to the person claiming indemnification or
in a case involving a claim of indemnification for attorneys' fees, (ii) by laws
rendering unenforceable indemnification contrary to federal or state securities
laws and the public policy underlying such laws and (iii) by laws limiting the
enforceability of provisions exculpating or exempting a party, or requiring
indemnification of a party, for liability for its own action or inaction, to the
extent the action or inaction involved gross negligence, recklessness, willful
misconduct or unlawful conduct.

      D. Furthermore, no opinion is given herein as to:

            (i) the enforceability of any right or obligation to the extent that
      the same has been varied by course of dealing or performance; or

            (ii) the enforceability of the provisions of Section 11.09 of the
      Credit Agreement (A) to the extent that a judgment not in Dollars is
      obtained in respect of the Credit Agreement in a jurisdiction other than
      the United States of America and the Borrower pays such judgment or (B)
      insofar as those provisions contemplate an alternative or additional cause
      of action for a claim that may have been merged with claims covered by an
      earlier judgment; or




                                                                     EXHIBIT C-3
                                                                          Page 4

            (iii) the enforceability of provisions in the Credit Documents to
      the effect that terms may not be waived or modified except in writing,
      which may be limited under certain circumstances; or

            (iv) the effect of the laws of any jurisdiction in which any Bank is
      located (other than the State of New York) that limit the interest, fees
      or other charges such Bank may impose; or

            (v) the enforceability of the right of setoff provided for in
      Section 11.02 of the Credit Agreement (A) in respect of an interest in
      Obligations purchased by a Bank pursuant to Section 11.06(b), to the
      extent the relevant purchase does not give rise to a direct obligation of
      OFP to such Bank, or (B) insofar as that right relates to setoff of
      unmatured Obligations or of obligations owed to OFP by Affiliates of the
      Banks or by Affiliates of the Administrative Agent.

      E. The opinion set forth in paragraph numbered 1 above is subject to
possible judicial action giving effect to governmental actions on foreign laws
affecting creditors' rights.

      We are members of the Bar of the State of New York and express no opinion
as to the laws of any jurisdiction other than the laws of the State of New York,
the General Corporation Law of the State of Delaware and the federal laws of the
United States of America.

      This opinion is rendered solely to the persons listed on Annex I hereto by
us as special New York counsel to OFP in connection with the transactions
contemplated by the Credit Documents. This opinion may not be relied upon in any
manner or for any purpose, or furnished to or relied upon by any other person,
without our prior written consent. The information set forth herein is as of the
date of this letter, and we disclaim any undertaking to advise the persons
listed on Annex I hereto of changes which thereafter may be brought to our
attention.

                                                     Very truly yours,




                                                                     EXHIBIT C-3
                                                                          Page 5

                                                                     EXHIBIT C-4

                FORM OF OPINION OF COUNSEL (UNITED KINGDOM) - OFP

TO:   The Banks named as parties to the
      Credit Agreement referred to below and
      Citibank, N.A., as Administrative
      Agent

            2002

Ladies and Gentlemen

Omnicom Finance Plc

We have acted as special English lawyers for Omnicom Finance Plc, a company
organised and existing under the laws of England and Wales ("Omnicom Plc"), in
connection with its authorisation of the execution and delivery of the following
documents (collectively, the "Credit Documents"):

      (a)   the 364-Day Credit Agreement dated as of April 25, 2002 between
            Omnicom Finance Inc., Omnicom Plc, Omnicom Capital Inc.
            (collectively, the "Borrowers"), the financial institutions
            expressed to be parties thereto (the "Banks") and Citibank, N.A., as
            Administrative Agent (the "Credit Agreement"); and

      (b)   the Notes of Omnicom Plc, if any, to be delivered pursuant to
            Section 2.05 of the Credit Agreement.

This opinion is delivered to you pursuant to Section 5.01(b) of the Credit
Agreement. Terms used herein which are defined in the Credit Agreement shall
have the respective meanings set forth in the Credit Agreement, unless otherwise
defined herein.

1     Documents Reviewed and Assumptions Made

      In connection with this opinion, we have examined the originals, or
      certified, conformed or reproduction copies of the Credit Agreement
      (including the Exhibits thereto), and such records and other documents as
      we have deemed necessary as the basis for the opinions hereinafter
      expressed.

      In our examination of the documents referred to above and for the purpose
      of rendering this opinion, we have assumed:-




                                                                     EXHIBIT C-4
                                                                          Page 2

1.1   the accuracy of all certificates referred to above, the genuineness of all
      signatures on all documents referred to above or on the originals thereof,
      and the conformity to original documents of all copies;

1.2   that the parties to the Credit Agreement other than Omnicom Plc have the
      corporate power and authority to enter into and perform each of the Credit
      Documents to which they are parties and that each of such Credit Documents
      has been duly authorised, executed and delivered by each such other party
      in accordance with all applicable laws;

1.3   that, subject to the position under English law being as set out in our
      opinion, the Credit Documents are legal, valid and binding obligations of
      Omnicom Plc under the law of New York; and

1.4   that the information disclosed by our search on [ ] 2002 at the Registrar
      of Companies for England and Wales and enquiry on [ ] 2002 at the Central
      Registry of Winding Up Petitions in relation to Omnicom Plc (which did not
      disclose the existence of any petition or resolution to wind up Omnicom
      Plc or to appoint an administrator for Omnicom Plc) was then accurate and
      has not since then been altered and that such search and enquiry did not
      fail to disclose any matters relevant for the purposes of this opinion.

      We have not sought independently to verify any of the above assumptions.

      We have also relied upon two certificates (the "Certificate" and the
      "Director's Certificate" respectively) of a Director and the Secretary of
      Omnicom Plc as to certain factual matters. Copies of the Certificate and
      the Director's Certificate are attached to this letter. We have not sought
      independently to verify the accuracy or completeness of the Certificate or
      the Director's Certificate.

2     Opinion

      Based upon the foregoing, and subject to the qualifications and further
      assumptions set forth in section 3 of this letter, we are of the opinion
      that:

2.1   Omnicom Plc (i) is a validly existing public limited company in "good
      standing" (as defined in paragraph 3.5 below) under the laws of England
      and Wales; (ii) has the power and authority to own its property and assets
      and to transact the business in which it is engaged (as such property,
      assets and business are described in the Certificate); and (iii) is not
      required to be qualified as a "foreign corporation" in order to do
      business in any jurisdiction within England and Wales.

2.2   Omnicom Plc has the corporate power to execute, deliver and perform the
      terms and provisions of each of the Credit Documents to which it is
      expressed to be a party and to borrow under the Credit Agreement and has
      taken all necessary corporate action to authorise the execution, delivery
      and performance by it of each of such Credit Documents and borrowing by




                                                                     EXHIBIT C-4
                                                                          Page 3

      it under the Credit Agreement. Omnicom Plc has duly executed the Credit
      Agreement. When the Notes are signed by one of the Directors of Omnicom
      Plc, whose names are set out in Appendix A to the Director's Certificate,
      given by Omnicom Plc pursuant to Section 5.01(a) of the Credit Agreement,
      such Notes will have been validly executed by Omnicom Plc.

2.3   The execution, delivery and performance by Omnicom Plc of the Credit
      Documents to which it is expressed to be a party, the compliance by it
      with the terms and provisions thereof and the borrowing by it under the
      Credit Agreement will: (i) not contravene any provision of any law,
      statute, rule or regulation of England and Wales; and (ii) not violate any
      provision of the Memorandum or Articles of Association of Omnicom Plc.

2.4   No order, consent, approval, licence, authorisation or validation of, or
      filing, recording or registration with (except as have been obtained or
      made prior to the date hereof), or exemption by, any governmental or
      public body or authority of or in England and Wales, is required to
      authorise, or is required in connection with: (i) the execution, delivery
      and performance by Omnicom Plc of any Credit Document to which Omnicom Plc
      is expressed to be a party; (ii) the borrowing by Omnicom Plc under the
      Credit Agreement; or (iii) the enforceability of any such Credit Document
      against Omnicom Plc.

2.5   If such matters were raised before them, the English Courts, in a properly
      presented case, would give effect to the choice of New York law as the
      governing law of each of the Credit Documents and to the consent by
      Omnicom Plc, in Section 11.08 of the Credit Agreement to the jurisdiction
      of courts sitting in the State of New York.

3     Qualifications

      This opinion is also subject to the qualifications set out below.

3.1   We express no opinion as to any law other than the law of England and
      Wales in force as at the date hereof and we express no opinion as to
      matters of fact.

3.2   The obligations of Omnicom Plc under the Credit Documents will be subject
      to any laws from time to time in effect relating to insolvency,
      administration, bankruptcy, liquidation or any other laws or legal
      procedures affecting generally the enforcement of creditors' rights, as
      well as the principles of equity.

3.3   The search at the Registrar of Companies referred to in paragraph 1.4 is
      not capable of conclusively revealing whether or not certain events have
      occurred, including the commencement of winding up or the making of an
      administration order or the appointment of a receiver, administrative
      receiver, administrator or liquidator, as notice of these matters may not
      be




                                                                     EXHIBIT C-4
                                                                          Page 4

      immediately filed with the Registrar of Companies and, when filed, may not
      be immediately available for public inspection.

3.4   The enquiry at the Central Registry of Winding Up Petitions referred to in
      paragraph 1.4 relates only to a compulsory winding-up and is not capable
      of conclusively revealing whether or not a petition in respect of a
      compulsory winding-up has been presented since details of a petition may
      not have been immediately entered on the records of the Central Registry
      or, in the case of a petition presented to a County Court, may not have
      been notified to the Central Registry or entered on such records at all.

3.5   There is no concept of "good standing" as such under English company law.
      Accordingly, the reference to "good standing" in paragraph 2.1 above
      should be taken to mean only that our search referred to above of records
      of the Registrar of Companies for England and Wales and enquiry of the
      Central Office of Winding Up Petitions did not reveal any appointment of,
      or resolution or petition to appoint, a liquidator, administrator or
      administrative receiver of Omnicom Plc, or that Omnicom Plc is delinquent
      in filing its statutory annual directors' report and accounts, or any
      notification by the Registrar of Companies of intention to strike Omnicom
      Plc's name off the Register of Companies.

3.6   The choice of a particular law to govern an agreement or document would
      not be recognised or upheld by the English Courts if the choice of law was
      not bona fide and legal or if there were reasons for avoiding the choice
      of law on the grounds of public policy. The choice of a particular law
      would not be upheld, for example, if it was made with the intention of
      evading the law of the jurisdiction with which the contract had its most
      substantial connection and which, in the absence of the chosen law, would
      have invalidated the contract or been inconsistent with it. We have not
      made any investigation into the bona fides of the parties to the Credit
      Documents; however we are not aware of any reason for an English Court to
      find that the choice of New York law to govern the Credit Documents is not
      bona fide or not legal, nor are we aware of any English public policy that
      would be violated by the enforcement of the Credit Documents in accordance
      with their respective terms.

3.7   Our opinions in paragraphs 2.3 and 2.4 above are based on and subject to
      the further assumption that all Loans made to Omnicom Plc pursuant to the
      Credit Agreement will be made by persons who are: (i) authorised persons
      (within the meaning of the Financial Services and Markets Act 2000) who
      have permission to accept deposits, or to effect or carry out contracts of
      insurance; or (ii) acting in the course of carrying on a business
      consisting wholly or to a significant extent of lending money; or (iii)
      otherwise described in paragraph 6(1) of the Financial Services and
      Markets Act 2000 (Regulated Activities) Order 2001.

The opinions expressed herein may not be relied upon in any manner or used for
any purpose by any person other than in relation to the Credit Documents by the
persons to




                                                                     EXHIBIT C-4
                                                                          Page 5

whom they are addressed. This opinion shall be governed by and construed in
accordance with English Law.

Yours faithfully




                               OMNICOM FINANCE PLC

                                   Certificate

      GUARANTY, dated as of April 25, 2002, made by OMNICOM GROUP INC., a
corporation organized and existing under the laws of New York (the "Guarantor").
Except as otherwise defined herein, terms used herein and defined in the Credit
Agreement (as hereinafter defined), if not otherwise defined herein, shall be
used herein as so defined.

                              W I T N E S S E T H :

      WHEREAS, Omnicom Finance Inc., Omnicom Capital Inc. and Omnicom Finance
Plc (the "Borrowers"), various financial institutions (the "Banks") and
Citibank, N.A., as Administrative Agent (the "Administrative Agent") (the Banks
and the Administrative Agent being hereinafter collectively referred to as the
"Guaranteed Parties") have entered into a 364-Day Credit Agreement, dated as of
April 25, 2002 (as modified, supplemented or amended from time to time, the
"Credit Agreement"), providing for the making of Loans in Dollars as
contemplated therein;

      WHEREAS, it is a condition precedent to the effectiveness of the Credit
Agreement referred to above that the Guaranty be executed and delivered in the
form hereof;

      WHEREAS, it is a condition to the making of Loans under the Credit
Agreement that the Guarantor shall have executed and delivered this Guaranty;
and

      WHEREAS, the Guarantor will obtain benefits as a result of the Loans made
to the Borrowers under the Credit Agreement and, accordingly, desires to execute
and deliver this Guaranty in order to satisfy the conditions described in the
two immediately preceding paragraphs;

      NOW, THEREFORE, in consideration of the foregoing and other benefits
accruing to the Guarantor, the receipt and sufficiency of which are hereby
acknowledged, the Guarantor hereby makes the following representations and
warranties to the Guaranteed Parties and hereby covenants and agrees with the
Guaranteed Parties as follows:

      1. The Guaranty. The Guarantor irrevocably and unconditionally guarantees
the full and prompt payment when due (whether by acceleration or otherwise) of
the principal of and interest on any Note issued under the Credit Agreement and
of all other obligations and liabilities (including, without limitation,
indemnities, fees and interest thereon) of the Borrowers now existing or
hereafter incurred under, arising out of or in connection with the Credit
Agreement and the due performance and compliance with the terms of the Credit
Agreement and the Notes by the Borrowers (all such principal, interest,
obligations and liabilities, collectively, the "Guaranteed Obligations"). All
payments by the Guarantor under this Guaranty, to the extent owing to the Banks
or the Administrative Agent, shall be made on the same basis as payments by the
Borrowers under Sections 4.02 and 4.03 of the Credit Agreement.

      2. Waiver of Notice, Etc. The Guarantor hereby waives notice of acceptance
of this Guaranty and notice of any liability to which it may apply, and waives
presentment, demand of payment, protest, notice of dishonor or nonpayment of any
such liability, suit or




taking of other action by any Guaranteed Party against, and any other notice to,
any party liable thereon (including the Guarantor or any other guarantor).

      3. Waiver of Suretyship Defenses. Any Guaranteed Party may at any time and
from time to time without the consent of, or notice to the Guarantor, without
incurring responsibility to the Guarantor, without impairing or releasing the
obligations of the Guarantor hereunder, upon or without any terms or conditions
and in whole or in part:

            (a) change the manner, place or terms of payment of, and/or change
      or extend the time of payment of, renew or alter, any of the Guaranteed
      Obligations, any security therefore, or any liability incurred directly or
      indirectly in respect thereof, and the guaranty herein made shall apply to
      the Guaranteed Obligations as so changed, extended, renewed or altered;

            (b) sell, exchange, release, surrender, realize upon or otherwise
      deal with in any manner and in any order any property by whomsoever at any
      time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
      Obligations or any liabilities (including any of those hereunder) incurred
      directly or indirectly in respect thereof or hereof, and/or any offset
      there against;

            (c) exercise or refrain from exercising any rights against the
      Borrowers or others or otherwise act or refrain from acting;

            (d) settle or compromise any of the Guaranteed Obligations, any
      security therefor or any liability (including any of those hereunder)
      incurred directly or indirectly in respect thereof or hereof, and may
      subordinate the payment of all or any part thereof to the payment of any
      liability (whether due or not) of the Borrowers to creditors of the
      Borrowers other than the Guaranteed Parties and the Guarantor;

            (e) apply any sums by whomsoever paid or howsoever realized to any
      liability or liabilities of the Borrowers to the Guaranteed Parties
      regardless of what liability or liabilities of the Borrowers remain
      unpaid;

            (f) consent to or waive any breach of, or any act, omission or
      default under, any of the Credit Documents, or otherwise amend, modify or
      supplement any of the Credit Documents or any of such other instruments or
      agreements; and/or

            (g) act or fail to act in any manner referred to in this Guaranty
      which may deprive the Guarantor of its right to subrogation against the
      Borrowers to recover full indemnity for any payments made pursuant to this
      Guaranty.

      4. Obligations Unconditional. The obligations of the Guarantor under this
Guaranty are absolute and unconditional and shall remain in full force and
effect without regard to, and shall not be released, suspended, discharged,
terminated or otherwise affected by, any circumstance or occurrence whatsoever,
including, without limitation: (a) any action or inaction


                                      -2-


by any Guaranteed Party as contemplated in Section 3 of this Guaranty; (b) any
invalidity, irregularity or unenforceability of all or part of the Guaranteed
Obligations or of any security therefor; or (c) to the fullest extent permitted
by law, any other circumstance or occurrence that would or might otherwise
release, suspend, discharge, terminate or otherwise affect the obligations of a
surety. This Guaranty is a primary obligation of the Guarantor, and is a
guaranty of payment, not merely collection.

      5. Subrogation. (a) The Guarantor hereby waives all rights of subrogation
which it may at any time otherwise have as a result of this Guaranty (whether
contractual, under Section 509 of the Bankruptcy Code, or otherwise) to the
claims of the Guaranteed Parties against the Borrowers or any other guarantor of
the Guaranteed Obligations (collectively, the "Other Parties") and all
contractual, statutory or common law rights of reimbursement, contribution or
indemnity from any Other Party which it may at any time otherwise have as a
result of this Guaranty. The Guarantor hereby further waives any right to
enforce any other remedy which the Guaranteed Parties now have or may hereafter
have against any Other Party, any endorser or any other guarantor of all or any
part of the indebtedness of the Borrowers and any benefit of, and any right to
participate in, any security or collateral given to or for the benefit of the
Guaranteed Parties to secure payment of the indebtedness of the Borrowers. The
Guarantor also waives all claims (as such term is defined in the Bankruptcy
Code) it may at any time otherwise have against any Other Party arising from any
transaction whatsoever, including, without limitation, its right to assert or
enforce any such claims.

      (b) Notwithstanding the provisions of the preceding clause (a), the
Guarantor shall have and be entitled to (i) all rights of subrogation otherwise
provided by law in respect of any payment it may make or be obligated to make
under this Guaranty and (ii) all claims (as defined in the Bankruptcy Code) it
would have against any Other Party in the absence of the preceding clause (a),
and to assert and enforce same, provided that no Default or Event of Default of
the type described in Section 9.05 of the Credit Agreement with respect to the
respective Other Party exists at the time of such assertion and enforcement.

      6. Representations and Warranties. In order to induce the Banks to make
the Loans, the Guarantor makes the following representations, warranties and
agreements:

            (a) Corporate Existence. Each of the Guarantor and its Subsidiaries
      (i) is a duly organized and validly existing corporation in good standing
      under the laws of the jurisdiction of its incorporation, (ii) has the
      power and authority to own its property and assets and to transact the
      business in which it is engaged and (iii) is duly qualified as a foreign
      corporation and in good standing in each jurisdiction where the ownership,
      leasing or operation of property or the conduct of its business requires
      such qualification, except where the failure to be so qualified could not
      have a material adverse effect on the business, operations, property,
      assets, condition (financial or otherwise) or (to the knowledge of the
      Guarantor) prospects of the Guarantor or of the Guarantor and its
      Subsidiaries taken as a whole.


                                      -3-


            (b) Action. The Guarantor has the corporate power to execute,
      deliver and perform the terms and provisions of this Guaranty and has
      taken all necessary corporate action to authorize the execution, delivery
      and performance by it of this Guaranty. The Guarantor has duly executed
      and delivered this Guaranty, and this Guaranty constitutes its legal,
      valid and binding obligation enforceable in accordance with its terms
      except as the enforceability thereof may be limited by applicable
      bankruptcy, insolvency, reorganization or other similar laws affecting
      creditors' rights generally and by general equitable principles
      (regardless of whether the issue of enforceability is considered in a
      proceeding in equity or at law).

            (c) No Breach. Neither the execution, delivery or performance by the
      Guarantor of this Guaranty, nor compliance by it with the terms and
      provisions hereof, (i) will contravene any provision of any law, statute,
      rule or regulation or any order, writ, injunction or decree of any court
      or governmental instrumentality, (ii) will conflict or be inconsistent
      with or result in any breach of any of the terms, covenants, conditions or
      provisions of, or constitute a default under, any indenture, mortgage,
      deed of trust, credit agreement, loan agreement or any other agreement,
      contract or instrument to which the Guarantor or any of its Subsidiaries
      is a party or by which it or any of its property or assets is bound or to
      which it may be subject or (iii) will violate any provision of the
      Certificate of Incorporation or Bylaws of the Guarantor or any of its
      Subsidiaries.

            (d) Approvals. No order, consent, approval, license, authorization
      or validation of, or filing, recording or registration with (except as

      required to authorize, or is required in connection with, (i) the
      execution, delivery and performance of this Guaranty or (ii) the legality,
      validity, binding effect or enforceability of this Guaranty.

            (e) Financial Condition. The consolidated statements of financial
      condition of the Guarantor and its Subsidiaries at December 31, 2001 and
      the related consolidated statements of income and retained earnings and
      cash flow of the Guarantor and its Subsidiaries for the fiscal year ended
      on such date and heretofore furnished to the Banks present fairly, in all
      material respects, the consolidated financial condition of the Guarantor
      and its Subsidiaries at the date of such statements of financial condition
      and the consolidated results of the operations of the Guarantor and its
      Subsidiaries for such fiscal year. All such financial statements have been
      prepared in accordance with generally accepted accounting principles and
      practices consistently applied. From December 31, 2001 through the date of
      this Guaranty, there has been no material adverse change in the business,
      operations, property, assets, condition (financial or otherwise) or (to
      the knowledge of the Guarantor) prospects of the Guarantor or of the
      Guarantor and its Subsidiaries taken as a whole.

            (f) Financial Disclosure. Except as fully reflected in the financial
      statements delivered pursuant to the preceding clause (e), there were as
      of the date hereof no


                                      -4-


      liabilities or obligations with respect to the Guarantor or any of its
      Subsidiaries of any nature whatsoever (whether absolute, accrued,
      contingent or otherwise and whether or not due) which, either individually
      or in aggregate, would be materially adverse to the Guarantor or to the
      Guarantor and its Subsidiaries taken as a whole.

            (g) Litigation. There are no actions, suits or proceedings pending
      or, to the best knowledge of the Guarantor, threatened (i) with respect to
      any Credit Document or (ii) that are reasonably likely to materially and
      adversely affect the business, operations, property, assets, condition
      (financial or otherwise) or (to the knowledge of the Guarantor) prospects
      of the Guarantor or of the Guarantor and its Subsidiaries taken as a
      whole.

            (h) True and Complete Disclosure. All factual information (taken as
      a whole) heretofore or contemporaneously furnished by or on behalf of the
      Guarantor in writing to any Bank (including, without limitation, all
      information contained herein) for purposes of or in connection with this
      Guaranty or any transaction contemplated herein is, and all other such
      factual information (taken as a whole) hereafter furnished by or on behalf
      of the Guarantor in writing to any Bank will be, true and accurate in all
      material respects on the date as of which such information is dated or
      certified and does not omit to state any fact necessary to make such
      information (taken as a whole) not misleading in any material respect at
      such time in light of the circumstances under which such information was
      provided.

            (i) Taxes. Each of the Guarantor and its Subsidiaries has filed all
      tax returns required to be filed (taking into account all valid
      extensions) by it and has paid all income taxes payable by it which have
      become due pursuant to such tax returns and all other taxes and
      assessments payable by it which have become due, other than those not yet
      delinquent and except for those contested in good faith and for which
      adequate reserves have been established. Each of the Guarantor and its
      Subsidiaries has paid, or has provided adequate reserves (in the good
      faith judgment of the management of the Guarantor) for the payment of, all
      federal and state income taxes applicable for all prior fiscal years and
      for the current fiscal year to the last day of the fiscal quarter
      immediately preceding the date hereof.

            (j) Capitalization. As of December 31, 2001, the authorized capital
      stock of the Guarantor consisted of (i) 1,000,000,000 shares of common
      stock, $.15 par value per share, of which 198,669,254 shares were issued
      and outstanding and (ii) 7,500,000 shares of preferred stock, $1.00 par
      value per share, none of which shares were issued and outstanding. All
      such outstanding shares have been duly and validly issued, are fully paid
      and non-assessable. Other than (x) certain options to purchase 17,743,823
      shares of common stock of the Guarantor (as of December 31, 2001) and
      performance units payable in cash and/or common stock in the discretion of
      the Compensation Committee of the Board of Directors of the Guarantor, (y)
      the Guarantor's Zero-Coupon Convertible Notes due 2031 and Zero-Coupon
      Convertible Notes due 2032, and (z) shares of common stock issuable under
      certain acquisition agreements to which the Guarantor is a party, the


                                      -5-


      Guarantor does not have outstanding any securities convertible into or
      exchangeable for its capital stock or outstanding any rights to subscribe
      for or to purchase, or any options for the purchase of, or any agreements
      providing for the issuance (contingent or otherwise) of, or any calls,
      commitments or claims of any character relating to, its capital stock.

            (k) Environmental Matters. Each of the Guarantor and its
      Subsidiaries is in compliance with all applicable statutes, regulations
      and orders of, and all applicable restrictions imposed by, all
      governmental bodies, domestic or foreign, in respect of the conduct of its
      business and the ownership of its property (including applicable statutes,
      regulations, orders and restrictions relating to environmental standards
      and controls), except such noncompliances as would not, in the aggregate,
      have a material adverse effect on the business, operations, property,
      assets, condition (financial or otherwise) or (to the knowledge of the
      Guarantor) prospects of the Guarantor or of the Guarantor and its
      Subsidiaries taken as a whole.

            (l) Material Subsidiaries Schedule I correctly sets forth the name
      of each Material Subsidiary of the Guarantor, the percentage ownership
      (direct and indirect) of the Guarantor in the voting securities of each
      such Material Subsidiary and also identifies the direct owner thereof, in
      each case as of the date hereof.

            (m) Investment Company Act. None of the Guarantor or any of its
      Subsidiaries is an "investment company" within the meaning of the
      Investment Company Act of 1940, as amended.

            (n) Public Utility Holding Company Act. None of the Guarantor, OFI

      company," or an "affiliate" of a "holding company" or a "subsidiary
      company" of a "holding company" within the meaning of the Public Utility
      Holding Company Act of 1935, as amended.

            (o) Ownership of Borrowers. The Guarantor owns all of the capital
      stock of each of OFI and OCI and Diversified Agency Services Limited

      other rights of whatever nature, necessary for the present conduct of its
      business, without any known conflict with the rights of others which, or

      such purchase, to acquire control of such corporation or (ii) the result
      of which is the ownership by the Guarantor and its Subsidiaries
      (including, without limitation, the Borrowers) of 10% or more of the

hereunder preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights, powers and remedies herein

remedies which any Guaranteed Party or the holder of any Note would otherwise
have. No notice to or demand on the Guarantor in any case shall entitle the

upon the occurrence of an Event of Default each of the Banks is hereby
authorized at any time or from time to time, without presentment, demand,
protest, or other notice of any kind to the Guarantor or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by such Bank (including, without limitation, by branches
and agencies of such Bank and its Affiliates wherever located) to or for the
credit or the account of the Guarantor against and on account of the obligations
of the Guarantor to such Bank under this Guaranty, irrespective of whether or
not such Bank shall have made any demand hereunder and although said
obligations, or any of them, shall be contingent or unmatured.

      14. Notices. All notices and other communications hereunder shall be made
at the addresses, in the manner and with the effect provided in Section 11.03 of
the Credit Agreement, provided that, for this purpose, the address of the

      15. Reinstatement. If claim is ever made upon any Guaranteed Party or the
holder of any Note for repayment or recovery of any amount or amounts received
in payment or on account of any of the Guaranteed Obligations and any of the
aforesaid payees repays all or part of said amount by reason of (a) any
judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property or (b) any settlement or
compromise of any such claim effected by such payee with any such claimant
(including the Guarantor), the Guarantor shall be and remain liable to the
aforesaid payees hereunder for the amount so repaid or recovered to the same
extent as if such amount had never originally been received by any such payee.

      16. Statute of Limitations. Any acknowledgment or new promise, whether by
payment of principal or interest or otherwise and whether by the Borrower or
others (including the Guarantor), with respect to any of the Guaranteed
Obligations shall, if the statute of limitations in favor of the Guarantor
against any Guaranteed Party or the holder of any Note shall have commenced to
run, toll the running of such statute of limitations, and if the period of such
statute of limitations shall have expired, prevent the operation of such statute
of limitations.


                                      -19-


      17. Generally Accepted Accounting Principles. The financial statements to
be furnished to the Banks pursuant hereto shall be made and prepared in
accordance with generally accepted accounting principles in the United States

utilize accounting principles and policies in conformity with those used to
prepare the historical financial statements delivered to the Banks pursuant to
Section 6(e) of this Guaranty.

      18. Governing Law, Submission to Jurisdiction. This Guaranty and the
rights and obligations of the Guaranteed Parties, the holders of the Notes and
the Guarantor hereunder shall be construed in accordance with and governed by
the law of the State of New York. Any legal action or proceeding with respect to
this Guaranty may be brought in the courts of the State of New York, and, by
execution and delivery of this Agreement, the Guarantor hereby irrevocably
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. The Guarantor agrees
that if at any time its principal place of business is not in the City and State
of New York, it will irrevocably designate, appoint and empower an agent for
purposes of this Section, in the City and State of New York, as its designee,
appointee and agent to receive, accept and acknowledge for and on its behalf,
and in respect of its property, service of any and all legal process, summons,
notices and documents which may be served in any such action or proceeding. If
for any reason such designee, appointee and agent shall cease to be available to
act as such, the Guarantor agrees to designate a new designee, appointee and
agent in New York City on the terms and for the purposes of this provision
satisfactory to the Administrative Agent. The Guarantor further irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the mailing of copies thereof by registered or
certified mail, postage prepaid, to the Guarantor at its address set forth
opposite its signature below, such service to become effective 30 days after
such mailing. Nothing herein shall affect the right of any Guaranteed Party or
the holder of any Note to serve process in any other manner permitted by law or
to commence legal proceedings or otherwise proceed against the Guarantor in any
other jurisdiction. The Guarantor hereby irrevocably waives any objection which
it may now or hereafter have to the laying of venue of any of the aforesaid
actions or proceedings arising out of or in connection with the Guaranty brought
in the courts referred to above and hereby further irrevocably waives and agrees
not to plead or claim in any such court that any such action or proceeding
brought in any such court has been brought in an inconvenient forum.

      19. Judgment Currency. The obligation of the Guarantor to make payment in
Dollars of any Guaranteed Obligations due hereunder shall not be discharged or
satisfied by any tender, or any recovery pursuant of any judgment, which is
expressed in or converted into any currency other than Dollars, except to the
extent such tender or recovery shall result in the actual receipt by the
respective Guaranteed Party in the United States of America of the full amount
of Dollars expressed to be payable in respect of any such Guaranteed
Obligations. The obligation of the Guarantor to make payment in Dollars as
aforesaid shall be enforceable as an alternative or additional cause of action
for the purpose of recovery in Dollars of the amount, if any, by


                                      -20-


which such actual receipt shall fall short of the full amount of Dollars
expressed to be payable in respect of any such Guaranteed Obligations, and shall
not be affected by judgment being obtained for any other sums due under this
Guaranty.
