                                   ARTICLE II

                        AMOUNTS AND TERMS OF THE ADVANCES

          SECTION 2.01. THE COMMITMENT. The Lender agrees, on the terms and
conditions hereinafter set forth, to make Advances to the Borrower in Dollars
from time to time on any Business Day during the period from the date hereof
until the Commitment Termination Date in an aggregate principal amount not to
exceed at any one time outstanding $30,000,000 (the "COMMITMENT"). Within the
foregoing limits and subject to the terms and conditions of this Agreement the
Borrower may borrow, prepay and reborrow the amount of the Commitment. Each
Advance shall be in a minimum amount of $1,000,000 or any whole multiple of
$1,000,000 in excess thereof.

          SECTION 2.02. ADVANCES. To request an Advance, the Borrower shall give
the Lender irrevocable, written notice of such Advance (i) in the case of a LIBO
Rate Advance, not later than 11:00 a.m. (New York City time) on the third
Business Day prior to the date of such Advance or (ii) in the case of a Base
Rate Advance, not later than 11:00 a.m. (New York City time) on the day of such
Advance. Each such notice shall be by telecopier, telex or cable and shall
specify the requested (i) date of such Advance, which shall be a Business Day,
(ii) Type of Advance, (iii) amount of such Advance and (iv) in the case of an
Advance consisting of a LIBO Rate Advance, initial Interest Period for such
Advance. The Lender will make the proceeds of each Advance available to the
Borrower by crediting the amount thereof, in immediately available funds, to an
account of the Borrower maintained with the Lender in New York City (or such
other account as the Lender and the Borrower may agree) (i) by 12:00 noon (New
York City time) in the case of a LIBO Rate Advance and (ii) by the end of the
same Business Day, if possible, in the case of a Base Rate Advance.

          SECTION 2.03. INTEREST ELECTIONS. Each Advance initially shall be of
the Type specified in the notice of such Advance and, in the case of a LIBO Rate
Advance, shall have an initial Interest Period as specified in such notice.
Thereafter, the Borrower may elect to convert such Advance to a different Type
or to continue such Advance as the same Type and, in the case of a LIBO Rate
Advance, may elect Interest Periods therefor, all as provided in this Section
2.03. The Borrower may elect different options with respect to different
portions of the affected Advance, in which case each such portion shall be
considered a separate Advance (PROVIDED, that each such portion, in the case of
a LIBO Rate Advance, shall be in a minimum amount of $1,000,000 or any whole
multiple of $1,000,000 in excess thereof). To make an election pursuant to this
Section 2.03, the Borrower shall notify the Lender of such election by telephone
by the time that a notice of Advance would be required under Section 2.02 if the
Borrower were requesting an Advance of the Type resulting from such election to
be made on the effective date of such election. Each such telephonic election
shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Lender of a written interest election request in a form approved
by the Lender and signed by the Borrower. Each telephonic and written interest
election request shall specify the following information:

                  (i) the Advance to which such interest election request
applies and, if different options are being elected with respect to different
portions thereof, the portions thereof to be

<PAGE>

                                      -11-

allocated to each resulting Advance (in which case the information to be
specified pursuant to clauses (iii) and (iv) of this paragraph shall be
specified for each resulting Advance);

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

          (iii) whether the resulting Advance is to be a Base Rate Advance or a
LIBO Rate Advance, or a specified combination thereof; and

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

If any such interest election request requests a LIBO Rate Advance but does not
specify an Interest Period, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration. If the Borrower fails to deliver a
timely and complete interest election request with respect to a LIBO Rate
Advance prior to the end of the Interest Period applicable thereto, then, unless
such Advance is repaid as provided herein, at the end of such Interest Period
such Advance shall be converted to a Base Rate Advance. Notwithstanding any
contrary provision hereof, if an Event of Default has occurred and is continuing
and the Lender so notifies the Borrower, then, so long as an Event of Default is
continuing (i) no outstanding Advance may be converted to or continued as a LIBO
Rate Advance and (ii) unless repaid, each LIBO Rate Advance shall be converted
to a Base Rate Advance at the end of the Interest Period applicable thereto.

          SECTION 2.04. TERMINATION, REDUCTION AND EXTENSION OF THE COMMITMENT.

          (a)  Unless previously terminated, the Commitment shall automatically
terminate on the Commitment Termination Date.

          (b)  The Borrower shall have the right to terminate or reduce the
Commitment at any time or from time to time; PROVIDED, that (i) the Borrower
shall give irrevocable, written notice of each such termination or reduction to
the Lender at least three Business Days before such termination or reduction,
(ii) each partial reduction shall be in a minimum amount of $5,000,000 or any
whole multiple of $1,000,000 in excess thereof and (iii) the Borrower shall not
terminate or reduce the Commitment if, after giving effect to any concurrent
prepayment of the Advances pursuant to Section 2.06, at any time, the aggregate
outstanding principal amount of the Advances at such time would exceed the
Commitment.

          (c)  The Commitment once terminated or reduced pursuant to this
Section 2.04 may not be reinstated.

          (d)  The Borrower may, by written notice to the Lender not less than
30 days and not more than 45 days prior to the Commitment Termination Date then
in effect (the "EXISTING COMMITMENT TERMINATION DATE"), request that the Lender
extend the Commitment Termination Date to the date falling 364 days after the
Existing Commitment Termination Date. The Existing Commitment Termination Date
shall be extended (effective as of the Existing Commitment

<PAGE>

                                      -12-

Termination Date) to the date falling 364 days after the Existing Commitment
Termination Date if the Lender so agrees, in its sole discretion; PROVIDED, that
no such extension shall be effective unless (i) no Event of Default or Default
shall have occurred and be continuing on the date of such request or on the
Existing Commitment Termination Date and (ii) the representations and warranties
made by the Borrower in Article IV hereof shall be true on and as of the date of
such request and the Existing Commitment Termination Date with the same force
and effect as if made on and as of such dates (or, if any such representation or
warranty is expressly stated to have been made as of a specific date, as of such
specific date). Each request for extension hereunder by the Borrower shall
constitute a certification by the Borrower to the effect set forth in clauses
(i) and (ii) above (both as of the date of such request and, unless the Borrower
otherwise notifies the Lender prior to the Existing Commitment Termination Date,
as of the Existing Commitment Termination Date). The Lender will notify the
Borrower in writing of its decision not less than 20 days and not more than 30
days prior to the Existing Commitment Termination Date; PROVIDED that in no
event may the Borrower request more than two such extensions. If any such
extension of the Existing Commitment Termination Date shall not become
effective, then the Commitment shall reduce to zero on the Existing Commitment
Termination Date and the Commitment Termination Date shall remain the Existing
Commitment Termination Date.

          SECTION 2.05. REPAYMENT OF ADVANCES; NOTE.

          (a)  The Borrower hereby unconditionally promises to pay to the Lender
the outstanding principal amount of the Advances on the Commitment Termination
Date.

          (b)  The Advances shall be evidenced by a single promissory note of
the Borrower (the "NOTE") in substantially the form of Exhibit A hereto, dated
the date hereof, payable to the Lender in a principal amount equal to the amount
of the Commitment and otherwise duly completed. The Lender is hereby authorized
by the Borrower to endorse on the schedule (or a continuation thereof) attached
to the Note the date, amount and Type of and the Interest Period (if any) for
each Advance made by the Lender to the Borrower hereunder and the date and the
amount of each payment or prepayment of principal of such Advance received by
the Lender; PROVIDED, that any failure by the Lender to make any such
endorsement shall not affect the obligations of the Borrower under the Note or
hereunder.

          SECTION 2.06. PREPAYMENT OF ADVANCES.

          (a)  The Borrower shall have the right at any time and from time to
time to prepay any Advance in whole or in part, subject to the requirements of
this Section 2.06.

          (b)  The Borrower shall notify the Lender by telephone (confirmed by
telecopy) of any optional prepayment hereunder (i) in the case of prepayment of
a LIBO Rate Advance, not later than 11:00 a.m. (New York City time) two Business
Days before the date of prepayment or (ii) in the case of prepayment of an Base
Rate Advance, not later than 11:00 a.m. (New York City time) on the date of
prepayment. Each such notice shall be irrevocable and shall specify the
prepayment date and the principal amount of each Advance or portion thereof to
be prepaid. Each partial prepayment of any Advance shall be in a minimum amount
of $1,000,000 or any whole multiple of $1,000,000 in excess thereof and shall be
applied to prepay any outstanding

<PAGE>

                                      -13-

Base Rate Advances before any LIBO Rate Advances. Prepayments shall be
accompanied by accrued interest to the extent required by Section 2.08 and all
amounts payable in connection therewith pursuant to Section 2.11.

          (c)  If either (i) there shall occur a Change in Control, or (ii) the
Borrower shall, with respect to any Significant Subsidiary, cease to own,
beneficially and of record, a majority of the issued and outstanding Voting
Stock of such Significant Subsidiary, the Borrower shall, within 5 Business Days
of the making of written demand by the Lender, prepay in full the outstanding
Loans together with accrued and unpaid interest thereon and all other amounts
payable hereunder, and upon the giving of such demand the Commitment shall
forthwith terminate. Nothing herein shall require a prepayment by reason of the
transfer of assets of a Significant Subsidiary to the Borrower or another
Significant Subsidiary.

          SECTION 2.07 FACILITY FEES; UTILIZATION FEES.

          (a)  The Borrower shall pay to the Lender a facility fee on the amount
of the Commitment (whether or not utilized) for the period from and including

Commitment is terminated or the Commitment Termination Date, at a rate per annum

in arrears on each Quarterly Date and on the earlier of the date the Commitment
terminates and the Commitment Termination Date. All facility fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (b)  The Borrower shall pay to the Lender a utilization fee on the
aggregate outstanding principal amount of the Advances during any period that
the aggregate outstanding principal amount of the Advances exceeds an amount
equal to 50% of the aggregate amount of the Commitment, at a rate per annum
equal to the Applicable Utilization Fee Rate. Accrued utilization fee shall be
payable on each day on which a payment of interest is due under Section 2.08.
All utilization fees shall be computed on the basis of a year of 360 days and
shall be payable for the actual number of days elapsed (including the first day

Period therefor at a rate per annum equal to the LIBO Rate for such Interest
Period plus the Applicable Margin.

          (d)  Accrued interest on each Advance shall be payable in arrears on
each Interest Payment Date for such Advance and upon termination of the
Commitment; PROVIDED, that (i) interest accrued pursuant to paragraph (c) of
this Section 2.08 shall be payable on demand, (ii) in the event of any repayment
or prepayment of any Advance, accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)

shall be required under regulations of the Board of Governors of the Federal

consisting of or including Eurocurrency Liabilities (or the equivalent),
additional interest on the unpaid principal amount of each LIBO Rate Advance,
from the date of such LIBO Rate Advance until such principal amount is paid in
full, at an interest rate per annum equal at all times to the remainder obtained
by subtracting (i) the LIBO Rate for the then current Interest Period for such
LIBO Rate Advance from (ii) the rate obtained by dividing such LIBO Rate by a
percentage equal to 100% MINUS the LIBO Rate Reserve Percentage for such
Interest Period, payable on each date on which interest is payable on such LIBO
Rate Advance. A certificate of the Lender setting forth the amount to which the
Lender is then entitled under this Section 2.08(e) shall be conclusive and
binding on the Borrower in the absence of manifest error.

          (f)  All computations of interest based on the Base Rate shall be made
on the basis of a year of 365 or 366 days, as the case may be, and all
computations of interest based on the LIBO Rate and computations of interest
pursuant to Section 2.08(e) shall be made on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding
the last day) occurring in the period for which such interest is payable.

          SECTION 2.09. ALTERNATE RATE OF INTEREST. If prior to the commencement
of any Interest Period for a LIBO Rate Advance the Lender determines (which
determination shall be conclusive absent manifest error) that:

          (a)  adequate and reasonable means do not exist for ascertaining the
LIBO Rate for such Interest Period; or

          (b)  the LIBO Rate for such Interest Period will not adequately and
fairly reflect the cost to the Lender of making or maintaining such Advance for
such Interest Period;

then the Lender shall give notice thereof to the Borrower by telephone or
telecopy as promptly as practicable thereafter certifying the reasons for its
determination and, until the Lender notifies the Borrower that the circumstances
giving rise to such notice no longer exist, (i) any interest election request
that requests the conversion of any Advance to, or continuation of any Advance
as, a LIBO Rate Advance shall be ineffective and (ii) if any notice of Advance
requests a LIBO Rate Advance, such Advance shall be made as a Base Rate Advance.

                                      -15-

          SECTION 2.10. INCREASED COSTS.

          (a)  If, due to either (i) the introduction of or any change (other
than any change by way of imposition or increase of reserve requirements
included in the LIBO Rate Reserve Percentage) in or in the interpretation of (to
the extent any such introduction or change occurs after the date hereof) any law
or regulation or (ii) the compliance with any guideline or request of any
central bank or other governmental authority adopted or made after the date
hereof (whether or not having the force of law), there shall be any increase in
the cost to the Lender of agreeing to make or making, funding or maintaining
LIBO Rate Advances, the Borrower shall from time to time, within 30 days after
delivery by the Lender to the Borrower of a certificate as to such change or
required compliance and the amount of such increased cost, pay to the Lender the
amount of the increased costs set forth in such certificate (which certificate
shall be conclusive and binding on the Borrower in the absence of manifest
error).

          (b)  If the Lender determines that compliance with any law or
regulation enacted or introduced after the date hereof or any guideline or
request of any central bank or other governmental authority adopted or made
after the date hereof (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by the Lender
or any corporation controlling the Lender and that the amount of such capital is
increased by or based upon the existence of the Lender's Commitment and other
commitments of this type, or the Advances, then, the Borrower shall, within 30
days after delivery by the Lender to the Borrower of a certificate as to such
required compliance, pay to the Lender the amount required to compensate the
Lender therefor (a certificate of the Lender as to such amount to be conclusive
and binding on the Borrower in the absence of manifest error).

          SECTION 2.11. BREAK FUNDING PAYMENTS. In the event of (a) the payment
of any principal of any LIBO Rate Advance other than on the last day of an
Interest Period therefor (including without limitation as a result of an Event
of Default), (b) the conversion of any LIBO Rate Advance other than on the last
day of an Interest Period therefor or (c) the failure to borrow, convert,
continue or prepay any Advance on the date specified in any notice delivered
pursuant hereto, then, in any such event, the Borrower shall compensate the
Lender for the loss, cost and expense attributable to such event, which shall be
the amount, as reasonably determined by the Lender, equal to the excess, if any,
of (i) the LIBO Rate for the balance of such Interest Period (or for the
Interest Period that would have commenced on such borrowing, conversion,
continuation or prepayment), over (ii) the amount of interest that the Lender
would earn on such principal amount for the balance of such Interest Period (or
for such Interest Period) if the Lender were to invest such principal amount for
such period at the interest rate that would be bid by the Lender (or an
Affiliate of the Lender) for Dollar deposits from other banks in the Eurodollar
market at the commencement of such period. A certificate of the Lender setting
forth any amount or amounts that the Lender is entitled to receive pursuant to
this Section 2.11 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay the Lender the amount shown as due
on any such certificate within 15 days after receipt thereof.

          SECTION 2.12. TAXES.

          (a)  Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; PROVIDED, that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.12) the Lender receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant governmental authority in accordance with applicable law.

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

          (c)  The Borrower shall indemnify the Lender, within 15 days after
written demand therefor, for the full amount of any Indemnified Taxes or Other
Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 2.12) paid by the Lender and
any penalties, interest and reasonable expenses arising therefrom or with
respect thereto, whether or not such Indemnified Taxes or Other Taxes were
correctly or legally imposed or asserted by the relevant governmental authority.
A certificate as to the amount of such payment or liability delivered to the
Borrower by the Lender shall be conclusive absent manifest error.

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

          (e)  The Lender agrees to use reasonable efforts, consistent in its
opinion with applicable law and with its policies, to minimize to the extent
reasonably possible any applicable Taxes.

          SECTION 2.13. PAYMENTS GENERALLY.

          (a)  The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest or fees, or under Section 2.10, 2.11
or 2.12, or otherwise) prior to 12:00 noon (New York City time) on the date when
due, in Dollars and immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Lender, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Lender at its office at 399 Park Avenue, New York, New York
10043. If any payment hereunder shall be due on a day that is not a Business
Day, the date for payment shall be extended to the next succeeding Business Day
and, in the case of any payment accruing interest, interest thereon shall be
payable for the period of such extension.

<PAGE>

                                      -17-

          (b)  If at any time insufficient funds are received by and available
to the Lender to pay fully all amounts of principal, interest and fees then due
hereunder, such funds shall be applied first, to pay interest then due
hereunder, then to pay fees and other amounts (other than principal) hereunder,
then to pay principal due hereunder.

               (c)  Without limiting any of the obligations of the Borrower or
the rights of the Lender hereunder, if the Borrower shall fail to pay when due
(whether at stated maturity, by acceleration or otherwise) any amount payable by
it hereunder or under the Note, the Lender is hereby authorized at any time and
from time to time, to the fullest extent permitted by applicable law, without
prior notice to the Borrower (which notice is expressly waived by the Borrower
to the fullest extent permitted by applicable law), to set off and appropriate
and apply against such amount any and all deposits (general or special, time or
demand, provisional or final, in any currency, matured or unmatured) with, and
any other obligations at any time held or owing by, the Lender or any branch or
agency thereof to or for the credit or account of the Borrower. The Lender shall
promptly provide notice to the Borrower of such set-off; PROVIDED, that failure
by the Lender to provide such notice to the Borrower shall not give the Borrower
any cause of action or right to damages or affect the validity of such set-off
and application. The rights of the Lender under this Section are in addition to
any other rights and remedies (including, without limitation, any other rights
of set-off) that the Lender may have.

the Lender to make each Advance (including, without limitation, the initial
Advance) shall be subject to the further conditions precedent that on the date
of such Advance (a) the representations and warranties set forth in Article IV

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  The Borrower represents and warrants to the Lender that:

          SECTION 4.01. ORGANIZATION; POWERS. Each of the Borrower and each
Significant Subsidiary is duly organized, validly existing and in good standing
under the laws of the jurisdiction of its organization, has all requisite power
and authority to carry on its business as now conducted and, except where the
failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, is qualified to do business in,
and is in good standing in, every jurisdiction where such qualification is
required.

          SECTION 4.02. AUTHORIZATION; ENFORCEABILITY. The execution, delivery
and performance of this Agreement and the Note by the Borrower are within the
Borrower's corporate powers and have been duly authorized by all necessary
corporate action. This Agreement has been duly executed and delivered by the
Borrower and constitutes, and the Note when duly executed and delivered for
value will constitute, a legal, valid and binding obligation of the Borrower,
enforceable in accordance with its terms, except as such enforceability may be
limited by (a) bankruptcy, insolvency, reorganization, moratorium or similar
laws of general applicability affecting the enforcement of creditors' rights and
(b) the application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

          SECTION 4.03. GOVERNMENT APPROVALS; NO CONFLICTS. The execution,
delivery and performance of this Agreement and the Note by the Borrower (a) do
not require any consent or approval of, registration or filing with, or any
other action by, any governmental authority, (b) will not violate any applicable
law or regulation or the charter, by-laws or other organizational documents of
the Borrower or any Subsidiary, (c) will not violate or result in a default
under any indenture, agreement or other instrument binding upon the Borrower or
any Subsidiary and (d)

<PAGE>

                                      -19-

will not result in the creation or imposition of any Lien on any asset of the
Borrower or any Subsidiary.

          SECTION 4.04. FINANCIAL CONDITION; NO MATERIAL ADVERSE CHANGE. The
Borrower has heretofore furnished to the Lender its audited consolidated balance
sheet and statements of income, stockholders' equity and cash flows as of and
for the fiscal year ended December 31, 1998, with the opinion thereon of
Pricewaterhouse Coopers LLP. Such financial statements present fairly the
consolidated financial position and consolidated results of operations and cash
flows of the Borrower and its Consolidated Subsidiaries as of such date and for
such period in accordance with GAAP. Since December 31, 1998, no event or
circumstance has occurred that has had or could reasonably be expected to have a
Material Adverse Effect.

          SECTION 4.05. YEAR 2000. The Borrower has reviewed and is currently
completing a detailed analysis of its operations with a view to assessing
whether it or any Subsidiary will be vulnerable to a Year 2000 Problem. Based on
such review, the Borrower does not believe that a Material Adverse Effect will
result from a Year 2000 Problem.

          SECTION 4.06. LITIGATION. There are no actions, suits or proceedings
by or before any arbitrator or governmental authority now pending against or, to
the knowledge of the Borrower, threatened against or affecting the Borrower or
any Subsidiary (i) as to which there is a reasonable possibility of an adverse
determination and that, if adversely determined, could reasonably be expected,
individually or in the aggregate, to result in a Material Adverse Effect or (ii)
that involve this Agreement or the Note or the transactions contemplated hereby
or thereby.

          SECTION 4.07. COMPLIANCE WITH LAWS AND AGREEMENTS. The Borrower and
each Significant Subsidiary are in compliance with all applicable laws
(including without limitation Environmental Laws, Tax laws and ERISA),
regulations and orders of any governmental authority and all indentures,
agreements and other instruments to which any of them is a party, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

          SECTION 4.08. INVESTMENT AND HOLDING COMPANY STATUS. Neither the
Borrower nor any Significant Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of 1940
or (b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of 1935.

          SECTION 4.09. MARGIN REGULATIONS. On the date hereof and immediately
after applying the proceeds of each Advance, not more than 25% of the value of
the assets subject to Section 5.01(j) or Section 5.01(l) hereof is represented
by margin stock as defined in Regulation U or X of the Board of Governors of the
Federal Reserve System.

          SECTION 4.10. TAXES. The Borrower and each Significant Subsidiary have
filed (or have obtained extensions of the time by which they are required to
file) all United States Federal income Tax returns and all other material Tax
returns required to be filed by them and have paid all Taxes shown due on the
returns so filed as well as all other material Taxes, assessments and
governmental charges which have become due, except such Taxes, if any, as are
being contested in good faith and as to which adequate reserves have been
provided.

          SECTION 4.11. ENVIRONMENTAL MATTERS. Each of the Borrower and each
Significant Subsidiary has obtained all environmental, health and safety
permits, licenses and other authorizations required under all Environmental Laws
to carry on its business as now being or as proposed to be conducted, except to
the extent failure to have any such permit, license or authorization could not
reasonably be expected to have a Material Adverse Effect. Each of such permits,
licenses and authorizations is in full force and effect and each of the Borrower
and each Significant Subsidiary is in compliance with the terms and conditions
thereof, and is also in compliance with all other limitations, restrictions,
conditions, standards, prohibitions, requirements, obligations, schedules and
timetables contained in any applicable Environmental Law or in any regulation,
code, plan, order, decree, judgment, injunction, notice or demand letter issued,
entered, promulgated or approved thereunder, except to the extent failure to
comply therewith could not (either individually or in the aggregate) reasonably
be expected to have a Material Adverse Effect.

          SECTION 4.12. EXISTING AGREEMENT. Schedule I hereto is a complete and
correct list of each credit agreement, loan agreement, indenture or other
similar arrangement providing for or otherwise relating to any Debt or any
extension of credit (or commitment for any extension of credit) to the Borrower
or any Significant Subsidiary outstanding on the date hereof.

          SECTION 4.13. SOLVENCY. The Borrower is and, after giving effect to
each Advance and the use of proceeds thereof, will be Solvent.

                                    ARTICLE V

                            COVENANTS OF THE BORROWER

          SECTION 5.01. GENERAL COVENANTS. So long as any principal of or
interest on any Advance or any other amount payable hereunder or under the Note
remains outstanding or the Commitment remains in effect, the Borrower covenants
and agrees that:

          (a) The Borrower will, and will cause each Significant Subsidiary to,
do or cause to be done all things necessary (i) to preserve its legal existence
and (ii) to preserve, renew and keep in full force and effect in all material
respects the rights, licenses, permits, privileges and franchises material to
the conduct of its business; PROVIDED, that the foregoing shall not prohibit any
merger, consolidation, liquidation or dissolution permitted under Section
5.01(j).

          (b) The Borrower will, and will cause each Significant Subsidiary to,
pay its obligations, including Tax liabilities, that, if not paid, could result
in a Material Adverse Effect before the same shall become delinquent or in
default, except where (a) the validity or amount thereof is being contested in
good faith by appropriate proceedings, (b) the Borrower or such Significant
Subsidiary has set aside on its books adequate reserves with respect thereto in
accordance with GAAP and (c) the failure to make payment pending such contest
could not reasonably be expected to result in a Material Adverse Effect.

          (c) The Borrower will, and will cause each Significant Subsidiary to,
comply with all applicable laws, statutes, rules, regulations and orders of,
including without limitation all

<PAGE>

                                      -21-

applicable Environmental Laws, Tax laws and ERISA, except for any non-compliance
which could not (either individually or in the aggregate) reasonably be expected
to have a Material Adverse Effect.

          (d) The Borrower will, and will cause each Significant Subsidiary to,
keep adequate records and books of account, in which complete entries will be
made in accordance with GAAP, and permit representatives of the Lender, upon
reasonable prior notice, to examine, copy and make extracts from its books and
records, to inspect any of its property, and to discuss its business and affairs
with its officers, all at such reasonable times and as often as reasonably
requested by the Lender.

          (e) The Borrower will, and will cause each Significant Subsidiary to,
preserve and maintain its property in good repair, working order and condition
and from time to time make all needful and proper repairs, renewals,
replacements, additions, betterments and improvements thereto, except in each
case where the failure to do so could not (either individually or in the
aggregate) reasonably be expected to have a Material Adverse Effect.

          (f) The Borrower will, and will cause each Significant Subsidiary to,
maintain insurance with financially sound and reputable insurance companies, and
with respect to property and risks of a character usually maintained by
corporations engaged in the same or similar business similarly situated, against
loss, damage and liability of the kinds and in the amounts customarily
maintained by such corporations.

          (g) The Borrower will furnish to the Lender:

               (i) as soon as available and in any event within 100 days after
          the end of each fiscal year of the Borrower, the consolidated balance
          sheet of the Borrower and its Consolidated Subsidiaries as at the end
          of such year and the consolidated statements of income and cash flows

          and for the portion of the fiscal year ended at the end of such fiscal
          quarter, and the related consolidated balance sheet as at the end of
          such fiscal quarter, setting forth in each case in comparative form
          the corresponding figures for the previous fiscal year and
          accompanied, in each case, by a certificate of the chief financial
          officer of the Borrower which certificate shall state that said
          consolidated financial statements fairly present the consolidated
          financial condition and results of operations of the Borrower and its
          Consolidated Subsidiaries in accordance with GAAP (except for the
          absence of footnotes) consistently applied as at the end of, and for,

               requirement of Section 4043(a) of ERISA that it be notified

               a failure to meet the minimum funding standard of Section 412
               of the Code or Section 302 of ERISA shall be a reportable event
               regardless of the issuance of any waivers in accordance with

                    (ii) the distribution under Section 4041 of ERISA of a
               notice of intent to terminate any Plan or the termination of

               and which has been an ERISA Affiliate for less than one year at
               the time such notice of intent is filed; PROVIDED, that such
               notice does not relate to a "distress termination" described
               in Section 4041(c) of ERISA;

                    (iii) the institution by PBGC of proceedings under Section
               4042 of ERISA for the termination of, or the appointment of a
               trustee to administer, any Plan, or the receipt by the Borrower
               or any ERISA Affiliate of a notice from a Multiemployer Plan
               that such action has been taken by PBGC with respect to such
               Multiemployer Plan;

                    (iv) the complete or partial withdrawal by the Borrower
               or any ERISA Affiliate under Section 4201 or 4204 of ERISA from
               a Multiemployer Plan, or the receipt

<PAGE>

                                      -23-

               by the Borrower or any ERISA Affiliate of notice from a
               Multiemployer Plan that is in reorganization or insolvency
               pursuant to Section 4241 or 4245 of ERISA or that it intends
               to terminate or has terminated under Section 4041A of ERISA;
               and

                    (v)  the institution of a proceeding by a fiduciary of
               any Multiemployer Plan against the Borrower or any ERISA
               Affiliate to enforce Section 515 of ERISA, which proceeding is
               not dismissed within 30 days;

               (vii) promptly after the sending or filing thereof, copies of all
          reports and registration statements which the Borrower files with the
          Securities and Exchange Commission or any national securities
          exchange;

               (viii) promptly upon the Borrower determining that there has been
          the occurrence of any Change in Control or upon the Borrower's ceasing
          to own, beneficially and of record, at least a majority of the issued
          and outstanding shares of Voting Stock of any Significant Subsidiary,
          notice of such event together a reasonably detailed description of
          such transaction; and

               (ix) such other information respecting the condition or
          operations, financial or otherwise, of the Borrower as the Lender may
          from time to time reasonably request.

               (h)  The Borrower shall promptly give to the Lender notice of all
legal or arbitral proceedings, and of all proceedings by or before any
governmental or regulatory authority or agency, affecting the Borrower or any
Significant Subsidiary, except proceedings which would not be likely to have a
Material Adverse Effect.

               (i)  The Borrower will use the proceeds of the Advances for its
general corporate purposes, including as commercial paper backstop, and/or to
finance the repurchase or redemption of outstanding shares of capital stock of

PROVIDED, further, that any Subsidiary may merge or consolidate with or into
another Person if no Default or Change in Control has occurred and is continuing

Subsidiary to, engage to any material extent in any business other than

Subsidiaries on the date

Borrower or any Significant Subsidiary from entering into transactions with (i)
any Affiliate the shares of which have been acquired by the Borrower or such
Subsidiary in satisfaction of a debt previously contracted in good faith if such

Insured Subsidiary shall be "adequately capitalized" within the meaning of 12
U.S.C. Section 1831o, as amended, reenacted or redesignated from time to time.

to pay its debts generally, or shall make a general assignment for the benefit
of creditors; or any proceeding shall be instituted by or against the Borrower
or such Significant Subsidiary seeking to adjudicate it as bankrupt or
insolvent, or seeking liquidation, winding up, reorganization, arrangement,
adjustment, protection, relief, or composition of it or its debts under any law
relating to bankruptcy, insolvency, moratorium or reorganization or relief of
debtors, or liquidation or winding up, or seeking the entry of an order for

                                   ARTICLE VII

                                  MISCELLANEOUS

          SECTION 7.01. AMENDMENTS, ETC. No amendment or waiver of any provision
of this Agreement or the Note, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Lender, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given. This
Agreement and the Note and the documents referred to herein and therein
constitute the entire agreement of the parties with respect to the subject
matter hereof and thereof.

          SECTION 7.02. NOTICES, ETC. All notices and other communications
provided for hereunder shall be in writing (including telecopier communication)
and mailed, telecopied or delivered, to the respective addresses set forth on

the mails or telecopied, respectively, except that notices and communications to
the Lender pursuant to Article II or VII shall not be effective until received
by the Lender.

          SECTION 7.03. NO WAIVER; REMEDIES. No failure on the part of the
Lender to exercise, and no delay in exercising, any right hereunder or under the
Note shall operate as a waiver thereof; nor shall any single or partial exercise

of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

          SECTION 7.04. COSTS, EXPENSES AND INDEMNIFICATION.

          (a)  The Borrower agrees to pay and reimburse to the Lender on demand
for reasonable costs and expenses incurred by the Lender in connection with the
preparation, negotiation, execution and delivery and administration of this
Agreement, the Note and the other documents to be delivered hereunder and
(subject to such limitation as has heretofore been agreed) and the modification,
amendment or enforcement thereof, including, without limitation, the reasonable
fees and out-of-pocket expenses of counsel for the Lender with respect thereto
and with respect to advising the Lender as to its rights and responsibilities
under or in connection with this Agreement.

          (b)  The Borrower hereby indemnifies the Lender and each of its
Affiliates and their respective officers, directors, employees, agents, advisors
and representatives (each, an "INDEMNIFIED PARTY") from and against any and all
claims, damages, losses, liabilities and expenses (including, without
limitation, fees and disbursements of counsel), joint or several, that may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or relating to any investigation,
litigation or proceeding or the preparation of any defense with respect thereto
arising out of or in connection with or relating to this Agreement or the
transactions contemplated hereby or any use made or proposed to be made with the
proceeds of the Advances, whether or not such investigation, litigation or
proceeding is brought by the Borrower, any of its shareholders or creditors, an
Indemnified Party or any other

<PAGE>

                                      -30-

Person, or an Indemnified Party is otherwise a party thereto, and whether or not
any of the conditions precedent set forth in Article III are satisfied or the
other transactions contemplated by this Agreement are consummated, except to the
extent such claim, damage, loss, liability or expense is found in a final,
non-appealable judgment by a court of competent jurisdiction to have resulted
from such Indemnified Party's gross negligence or willful misconduct.

          SECTION 7.05. ASSIGNMENTS AND PARTICIPATIONS.

          (a)  The Lender may, with the consent of the Borrower (which shall not
be unreasonably withheld), assign to another Person all or a portion of its
rights and obligations under this Agreement (including, without limitation, all
or a portion of the Commitment, the Advances and the Note); PROVIDED, HOWEVER,
that no such consent by the Borrower shall be required in the case of any
assignment to an Affiliate of the Lender; and PROVIDED, FURTHER, that any such
partial assignment shall be in an amount at least equal to $5,000,000 or in an
integral multiple of $1,000,000 in excess thereof.

          (b)  The Lender may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitment,
the Advances and the Note); PROVIDED, HOWEVER, that the Lender's obligations
under this Agreement (including, without limitation, its Commitment hereunder)
shall remain unchanged.

          (c)  The Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
7.05, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower or any of its Subsidiaries
furnished to the Lender by or on behalf of the Borrower.

          (d)  Notwithstanding any other provision set forth in this Agreement,
the Lender may at any time create a security interest in all or any portion of
its rights under this Agreement (including, without limitation, the Advances and
the Note) in favor of any Federal Reserve Bank in accordance with Regulation A
of the Board of Governors of the Federal Reserve System.

          (e)  All amounts payable by the Borrower to the Lender under Sections
2.08(e), 2.10, 2.11, 2.12 and 7.04(b) shall be determined as if the Lender had
not sold or agreed to sell any participations in the Advances or the Note or its
Commitment and as if the Lender were funding each of such Advances and
Commitment in the same way that it is funding the portion of such Advances and
Commitment in which no participations have been sold.

          SECTION 7.06. GOVERNING LAW; SUBMISSION TO JURISDICTION. This
Agreement and the Note shall be governed by, and construed in accordance with,
the law of the State of New York. The Borrower hereby submits to the
nonexclusive jurisdiction of the United States District Court for the Southern
District of New York and of any New York state court sitting in New York County
for the purposes of all legal proceedings arising out of or relating to this
Agreement or the transactions contemplated hereby. The Borrower irrevocably
waives, to the fullest extent permitted by applicable law, any objection that it
may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum.

                                      -31-

          SECTION 7.07. SEVERABILITY. In case any provision in this Agreement or
in the Note shall be held to be invalid, illegal or unenforceable, such
provision shall be severable from the rest of this Agreement or the Note, as the
case may be, and the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

          SECTION 7.08. EXECUTION IN COUNTERPARTS. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

          SECTION 7.09. SURVIVAL. The obligations of the Borrower under Sections
2.08(e), 2.10, 2.11, 2.12 and 7.04 shall survive the repayment of the Advances
and the termination of the Commitment. Each representation and warranty made or
deemed to be made herein or pursuant hereto shall survive the making of such
representation and warranty, and the Lender shall not be deemed to have waived,
by reason of making any Advance, any Default or Event of Default that may arise
by reason of such representation or warranty proving to have been false or
misleading.

          SECTION 7.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER AND THE
LENDER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF
OR RELATING TO THIS AGREEMENT, THE NOTE OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          SECTION 7.11 NO FIDUCIARY RELATIONSHIP. The Borrower acknowledges that
the Lender has no fiduciary relationship with, or fiduciary duty to, the
Borrower arising out of or in connection with this Agreement or the Note, and
the relationship between the Lender and the Borrower is solely that of creditor
and debtor. This Agreement does not create a joint venture among the parties.

          SECTION 7.12 NO RELIANCE. The Lender represents and warrants that it
in good faith has not relied and will not rely upon any margin stock as
collateral in entering into this Agreement or making or maintaining the
Advances.

                                 [FORM OF NOTE]

U.S.$30,000,000                                        Dated:  _______ __, 1999

         FOR VALUE RECEIVED, the undersigned, M & T BANK CORPORATION, a
_________ corporation (the "BORROWER"), HEREBY PROMISES TO PAY to the order of
CITIBANK, N.A. (the "LENDER") for the account of its Applicable Lending Office
(as defined in the Credit Agreement referred to below) on the Commitment
Termination Date (as so defined) the principal sum of U.S.$30,000,000 (THIRTY
MILLION UNITED STATES DOLLARS) or, if less, the aggregate outstanding principal
amount of the Advances (as defined below) pursuant to the Credit Agreement.

         The Borrower promises to pay interest on the unpaid principal amount of
each Advance from the date of such Advance until such principal amount is paid
in full, at such interest rates, and payable at such times, as are specified in
the Credit Agreement.

         Both principal and interest are payable in lawful money of the United
States of America at the office of the Lender at 399 Park Avenue, New York, New
York 10043, in same day funds. Each Advance made by the Lender to the Borrower
pursuant to the Credit Agreement, and all payments made on account of principal
thereof, shall be recorded by the Lender and, prior to any transfer hereof,
endorsed on the grid attached hereto which is part of this Note; PROVIDED, that
the failure of the Lender to make any such recordation or endorsement shall not
affect the obligations of the Borrower hereunder or under the Credit Agreement.

         This Note is the Note referred to in, and is entitled to the benefits
of, the Credit Agreement dated as of November 19, 1999 (the "CREDIT AGREEMENT",
the terms defined therein being used herein as therein defined) between the
Borrower and the Lender. The Credit Agreement contains provisions for
acceleration of the maturity hereof upon the happening of certain stated events
and also for prepayments on account of principal hereof prior to the maturity
hereof upon the terms and conditions therein specified.

         The Borrower hereby waives presentment, demand, protest and notice of
any kind. No failure to exercise, and no delay in exercising, any rights
hereunder on the part of the holder hereof shall operate as a waiver of such
rights.

         This Note shall be governed by, and construed in accordance with, the
law of the State of New York, United States.
