                  (A) Initially, from January 26, 1999, until changed hereunder
in accordance with the following provisions, the Applicable Margin will be 2.00%
per annum. Commencing with the fiscal quarter of Lessee ending on or nearest to
March 31, 1999, and continuing with each fiscal quarter thereafter, Lessor will
determine the Applicable Margin in accordance with the foregoing pricing grid
table, based on the ratio of (x) the Funded Indebtedness of the Companies as of
the end of the fiscal quarter, to (y) the EBITDA of the Companies for the four
consecutive fiscal quarters ended on the last day of the fiscal quarter, as
identified in the pricing grid table. Changes in the Applicable Margin based
upon changes in such ratio shall become effective on the first day of the month
following the receipt by Lessor pursuant to Section IV(b)(i) or (ii) of the
financial statements of Lessee and it Subsidiaries, accompanied by the
certificate and calculations referred to in Section IV(b)(iii), demonstrating
the computation of such ratio, based upon the ratio in effect at the end of the
applicable period covered (in whole or in part) by such financial statements.

                  (B) Notwithstanding the above provisions, during any period
when an Event of Default has occurred and is continuing, the Applicable Margin
shall be the highest rate per annum indicated therefor in the foregoing pricing
grid table, regardless of the ratio of Funded Indebtedness to EBITDA at such
time. Notwithstanding the above provisions, but subject to the preceding
sentence, during any period when Borrower has failed to timely deliver its
consolidated financial statements referred to in subsection IV(b)(i) or (ii),
accompanied by the certificate and calculations referred to in subsection
IV(b)(iii), the Applicable Margin shall be the rate per annum indicated for the
level in the foregoing pricing grid table that is one level higher than the
level that is otherwise then currently in effect, regardless of the ratio of
Funded Indebtedness to EBITDA at such time.

                  (C) Any changes in the Applicable Margin shall be determined
by Lessor in accordance with the above provisions and Lessor will promptly
provide notice of such determinations to Lessee. Any such determination by
Lessor pursuant to the above provisions shall be conclusive and binding absent
manifest error. The Applicable Margin is subject in all respects to compliance
by Lessee with Section XXIII(b) of the Lease, and this schedule of levels for
the Applicable Margin is not intended to waive or otherwise excuse a violation
of Section XXIII(b) of the Lease; if that Section is violated, the Daily Lease
Rate Factor will increase as set forth in Section XIX(j) of the Lease."

                  3.       Representations and Warranties.
                           -------------------------------

                  (A) Lessee hereby represents and warrants to Lessor that all

obligation of Lessee, enforceable against Lessee in accordance with their

Amendment and its performance of the Lease Agreement and the Disbursement
Schedules, as amended hereby, have been authorized by all requisite corporate
action and will not (1) violate (a) any order of any court, or any rule,

                  (C) This Amendment may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when

         (A) Initially, from January 26, 1999, until changed hereunder in
accordance with the following provisions, the Applicable Margin will be 2.00%
per annum. Commencing with the fiscal quarter of Lessee ending on or nearest to
March 31, 1999, and continuing with each fiscal quarter thereafter, Lessor will
determine the Applicable Margin in accordance with the foregoing pricing grid
table, based on the ratio of (x) the Funded Indebtedness of the Companies as of
the end of the fiscal quarter, to (y) the EBITDA of the Companies for the four
consecutive fiscal quarters ended on the last day of the fiscal quarter, as
identified in the pricing grid table. Changes in the Applicable Margin based
upon changes in such ratio shall become effective on the first day of the month
following the receipt by Lessor pursuant to Section IV(b)(i) or (ii) of the
financial statements of Lessee and it Subsidiaries, accompanied by the
certificate and calculations referred to in Section IV(b)(iii), demonstrating
the computation of such ratio, based upon the ratio in effect at the end of the
applicable period covered (in whole or in part) by such financial statements.

         (B) Notwithstanding the above provisions, during any period when an
Event of Default has occurred and is continuing, the Applicable Margin shall be
the highest rate per annum indicated therefor in the foregoing pricing grid
table, regardless of the ratio of Funded Indebtedness to EBITDA at such time.
Notwithstanding the above provisions, but subject to the preceding sentence,
during any period when Borrower has failed to timely deliver its consolidated
financial statements referred to in subsection IV(b)(i) or (ii), accompanied by
the certificate and calculations referred to in subsection IV(b)(iii), the
Applicable Margin shall be the rate per annum indicated for the level in the
foregoing pricing grid table that is one level higher than the level that is
otherwise then currently in effect, regardless of the ratio of Funded
Indebtedness to EBITDA at such time.

         (C) Any changes in the Applicable Margin shall be determined by Lessor
in accordance with the above provisions and Lessor will promptly provide notice
of such determinations to Lessee. Any such determination by Lessor pursuant to
the above provisions shall be conclusive and binding absent manifest error. The
Applicable Margin is subject in all respects to compliance by Lessee with
Section XXIII(b) of the Lease, and this schedule of levels for the Applicable
Margin is not intended to waive or otherwise excuse a violation of Section
XXIII(b) of the Lease; if that Section is violated, the Daily Lease Rate Factor
will increase as set forth in Section XIX(j) of the Lease.

         "INTERIM INTEREST PERIOD" or "INTEREST PERIOD" shall mean the period
beginning on the date of this Schedule and ending on the same day of each month
thereafter during the Interim Lease Term.

         "INTEREST RATE" shall mean that percentage per annum calculated as the
sum of the LIBOR Rate redetermined monthly, plus sixty (60) basis points.

         "LIBOR RATE" shall mean, with respect to any Interim Interest Period
occurring during the term of the Lease, an interest rate per annum equal at all
times during such Interim Interest Period to the quotient of (1) the rate per
annum as determined by Lessor at which deposits of U.S. Dollars in immediately
available and freely transferable funds are offered at 11:00 a.m. (London,
England time) two (2) Business Days before the commencement of such Interim
Interest Period to major banks in the London interbank market for a period of
one (1) month and in an amount equal or comparable to the Capitalized Lessor's
Cost, divided by (2) a number equal to 1.00 minus the aggregate (without
duplication) of the rates (expressed as a decimal fraction) of the LIBOR Reserve
Requirements current on the date three (3) Business Days prior to the first day
of the Interim Interest Period.

         "LIBOR RESERVE REQUIREMENTS" shall mean the daily average for the
applicable Interest Period of the maximum rate applicable to Lessor or its
Participants at which reserves (including, without limitation, any supplemental,
marginal and emergency reserves) are imposed during such Interest Period by the
Board of Governors of the Federal Reserve System (or any successor) on
"Eurocurrency liabilities", as


                                      -3-

<PAGE>   9


defined in such Board's Regulation D (or in respect of any other category of
liabilities that include deposits by reference to which the interest rates on
Eurodollar loans is determined or any category of extensions of credit or other
assets that include loans by non-United States offices of any lender to United
States residents), having a term equal to such Interest Period, subject to any
amendments of such reserve requirement by such Board or its successor, taking
into account any transitional adjustments thereto.

         If at any time Lessor or any Participant (or, without duplication, the
bank holding company of which such Participant is a subsidiary) determines that
either adequate and reasonable means do not exist for ascertaining the LIBOR
Rate, or it becomes impractical for Lessor or any Participant to obtain funds to
make or maintain the financing hereunder with interest at the LIBOR Rate, or
Lessor or any Participant reasonably determines that, as a result of changes to
applicable law after the date of execution of the Agreement, or the adoption or
making after such date of any interpretations, directives or regulations
(whether or not having the force of law) by any court, governmental authority or
reserve bank charged with the interpretation or administration thereof, it shall
be or become unlawful or impossible to make, maintain, or fund the transaction
hereunder at the LIBOR Rate, then Lessor promptly shall give notice to Lessee of
such determination and Lessor and Lessee shall negotiate in good faith a
mutually acceptable alternative method of calculating the Interest Rate and
shall execute and deliver such documents as reasonably may be required to
incorporate such alternative method of calculating the Interest Rate in this
Schedule, within thirty (30) days after the date of Lessor's notice to Lessee.
If the parties are unable mutually to agree to such alternative method of
calculating the Interest Rate in a timely fashion, (a) effective on the
commencement of the next succeeding Interest Period or the date that it becomes
impractical for Lessor or any Participant to maintain the financing hereunder
with interest at the LIBOR Rate as aforesaid, as the case may be, the Interest
Rate shall become a floating rate equal to the Federal Funds Rate plus sixty
(60) basis points, and (b) on the Rent Payment Date next succeeding the
expiration of such thirty (30) day period Lessee shall purchase all (but not
less than all) of the Disbursement Equipment described on all Disbursement
Schedules executed pursuant to the Agreement and shall pay to Lessor, in cash,
the purchase price for the Disbursement Equipment so purchased, determined as
hereinafter provided. (As used herein, "Federal Funds Rate" means the rate of
interest, as reasonably determined by Lessor, paid by or available to Lessor for
the purchase of "federal funds" at the time or times in question on a daily
overnight basis.) The purchase price of the Disbursement Equipment shall be an
amount equal to all amounts disbursed by Lessor in respect of that Disbursement
Equipment, together with all rent and other sums then due on such date, plus all
taxes and charges upon sale and all other reasonable and documented expenses
incurred by Lessor in connection with such sale. Upon satisfaction of the
conditions specified in this Paragraph, Lessor will transfer, on an AS IS, WHERE
IS BASIS, all of Lessor's interest in and to the Disbursement Equipment. Lessor
shall not be required to make and may specifically disclaim any representation
or warranty as to the condition of the Disbursement Equipment and other matters
(except that Lessor shall warrant that it conveyed whatever interest it received
in such Disbursement Equipment free and clear of any Lien created by Lessor).
Lessor shall execute and deliver to Lessee such Uniform Commercial Code
statements of termination as reasonably may be required in order to terminate
any interest of Lessor in and to the Disbursement Equipment.

         3. Lessee shall pay to Lessor, for the account of each Participant,
from time to time, the amounts as such Participant may determine to be necessary
to compensate it for any costs which such Participant determines are
attributable to its making or maintaining its interest in the Lease and the
Disbursement Equipment (the "Interest") or any reduction in any amount
receivable by such Participant in respect of any such Interest (such increases
in costs and reductions in amounts receivable being herein called "Additional
Costs"), resulting from any Regulatory Change (as defined below) which:

            (i) changes the basis of taxation of any amounts payable to Lessor
            for the account of such Participant in respect of such Interest
            (other than taxes imposed on or measured by the overall net income
            of such Participant in respect of the interest by the jurisdiction
            in which such Participant has its principal office or its lending
            office); or


                                      -4-

<PAGE>   10


            (ii) imposes or modifies any reserve, special deposit or similar
            requirements relating to any extensions of credit or other assets
            of, or any deposits with or other liabilities of, such Participant;
            or

            (iii) imposes any other condition affecting this Lease or any
            Interest.

For purposes hereof, "Regulatory Change" shall mean any change after the date of
this Lease in United States federal, state or foreign law or regulations
(including, without limitation, Regulation D of the Board of Governors of the
Federal Reserve System (or any successor), as amended or supplemented from time
to time) or the adoption or making after such date of any interpretation,
directive or request applying to a class of banks including any Participant or
under any United States federal, state or foreign law and whether or not failure
to comply therewith would be unlawful) by any court or governmental or monetary
authority charged with the interpretation or administration thereof. In
addition, whenever Lessee shall revoke any Disbursement Funding Notice or shall
for any other reason fail to take a disbursement pursuant thereto or shall fail
otherwise to comply therewith, then, in each case on the demand of Lessor or any
Participant, Lessee shall pay that Person such amount as will compensate it for
any loss, cost or loss of profit incurred by it by reason of its liquidation or
reemployment of deposits or other funds.

         Without limiting the effect of the foregoing Paragraph (but without
duplication), Lessee shall pay to Lessor, for the account of each Participant,
from time to time on request such amounts as such Participant may determine to
be necessary to compensate such Participant (or, without duplication, the bank
holding company of which such Participant is a subsidiary) for any costs which
it determines are attributable to the maintenance by such Participant (or any
lending office or such bank holding company), pursuant to any law or regulation
or any interpretation, directive or request (whether or not having the force of
law) of any court or governmental or monetary authority (i) following any
Regulatory Change or (ii) implementing any risk-based capital guideline or
requirement (whether or not having the force of law and whether or not the
failure to comply therewith would be unlawful) heretofore or hereafter issued by
any government or governmental or supervisory authority implementing at the
national level the Basle Accord (including, without limitation, the Final
Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve
System (12 C.F.R. Part 208, Appendix A; 12 C.F.R. Part 225, Appendix A) and the
Final Risk-Based Capital Guidelines of the Office of the Comptroller of the
Currency (12 C.F.R. Part 3, Appendix A)), of capital in respect of such
Participant's Interest (such compensation to include, without limitation, an
amount equal to any reduction of the rate of return on assets or equity of such
Participant (or any lending office or bank holding company) to a level below
that which such Participant (or any lending office or bank holding company)
could have achieved but for such law, regulation, interpretation, directive or
request). For purposes of this Paragraph, "Basle Accord" shall mean the
proposals for risk-based capital framework described by the Basle Committee on
Banking Regulations and Supervisory Practices in its paper entitled
"International Convergence of Capital Measurement and Capital Standards" dated
July 1988, as amended, modified and supplemented and in effect from time to time
or any replacement thereof.

         Each Participant shall notify Lessee of any event occurring after the
date of this Lease that will entitle such Participant to compensation under the
preceding two Paragraphs as promptly as practicable, but in any event within
thirty (30) days, after such Participant obtains actual knowledge thereof;
provided, that (i) if such Participant fails to give such notice within thirty
(30) days after it obtains actual knowledge of such an event, such Participant
shall, with respect to compensation payable pursuant to the preceding two
Paragraphs in respect of any costs resulting from such event, only be entitled
to payment under the referenced Paragraphs for costs incurred from and after the
date thirty (30) days prior to the date that such Participant does give such
notice, and (ii) such Participant will designate a different lending office for
the Interest if such designation will avoid the need for, or reduce the amount
of, such compensation and will not, in the sole opinion of such Participant, be
disadvantageous to such Participant. Each Participant will furnish to Lessee a
certificate setting forth the basis and amount of each request by such
Participant for

                                      -5-

<PAGE>   11


compensation under the preceding two Paragraphs. Determinations and allocations
by each Participant for purposes of the preceding two Paragraphs shall be
conclusive, absent manifest error.

D.       Insurance.
         ----------

         1. Public Liability: $1,000,000 total liability per occurrence and
$2,000,000 in the aggregate, with excess liability in umbrella form of
$10,000,000 per occurrence and in the aggregate, with a maximum deductible
amount of (a) $1,500,000 per occurrence or (b) an amount equal to $1,500,000 per
occurrence plus the amount of any reserves specifically allocated by Lessee for
this type of liability that are satisfactory to Lessor, but in no event greater
than $2,500,000 per occurrence.

         2. Casualty and Property Damage: An amount equal to the higher of the
full replacement cost of each unit of Disbursement Equipment or the amounts
disbursed by Lessor in respect of each unit of Disbursement Equipment, with a
maximum deductible amount of $1,000,000 per occurrence.

         This Schedule is not binding or effective with respect to the Agreement
or Equipment until executed on behalf of Lessor and Lessee by an authorized
representative of Lessor and Lessee, respectively.

         IN WITNESS WHEREOF, Lessee and Lessor have caused this Schedule to be
executed by their duly authorized representatives as of the date first above
written.

</TABLE>

         (A) Initially, from January 26, 1999, until changed hereunder in
accordance with the following provisions, the Applicable Margin will be 2.00%
per annum. Commencing with the fiscal

                                      -2-

quarter of Lessee ending on or nearest to March 31, 1999, and continuing with
each fiscal quarter thereafter, Lessor will determine the Applicable Margin in
accordance with the foregoing pricing grid table, based on the ratio of (x) the
Funded Indebtedness of the Companies as of the end of the fiscal quarter, to (y)
the EBITDA of the Companies for the four consecutive fiscal quarters ended on
the last day of the fiscal quarter, as identified in the pricing grid table.
Changes in the Applicable Margin based upon changes in such ratio shall become
effective on the first day of the month following the receipt by Lessor pursuant
to Section IV(b)(i) or (ii) of the financial statements of Lessee and it
Subsidiaries, accompanied by the certificate and calculations referred to in
Section IV(b)(iii), demonstrating the computation of such ratio, based upon the
ratio in effect at the end of the applicable period covered (in whole or in
part) by such financial statements.

         (B) Notwithstanding the above provisions, during any period when an
Event of Default has occurred and is continuing, the Applicable Margin shall be
the highest rate per annum indicated therefor in the foregoing pricing grid
table, regardless of the ratio of Funded Indebtedness to EBITDA at such time.
Notwithstanding the above provisions, but subject to the preceding sentence,
during any period when Borrower has failed to timely deliver its consolidated
financial statements referred to in subsection IV(b)(i) or (ii), accompanied by
the certificate and calculations referred to in subsection IV(b)(iii), the
Applicable Margin shall be the rate per annum indicated for the level in the
foregoing pricing grid table that is one level higher than the level that is
otherwise then currently in effect, regardless of the ratio of Funded
Indebtedness to EBITDA at such time.

         (C) Any changes in the Applicable Margin shall be determined by Lessor
in accordance with the above provisions and Lessor will promptly provide notice
of such determinations to Lessee. Any such determination by Lessor pursuant to
the above provisions shall be conclusive and binding absent manifest error. The
Applicable Margin is subject in all respects to compliance by Lessee with
Section XXIII(b) of the Lease, and this schedule of levels for the Applicable
Margin is not intended to waive or otherwise excuse a violation of Section
XXIII(b) of the Lease; if that Section is violated, the Daily Lease Rate Factor
will increase as set forth in Section XIX(j) of the Lease."

         "INTEREST PERIOD" shall mean the period beginning on the Basic Term
Commencement Date and ending on the next Rent Payment Date, and each subsequent
quarterly period.

         "INTEREST RATE" shall mean that percentage per annum calculated as the
sum of the LIBOR Rate redetermined quarterly, plus sixty (60) basis points.

         "LIBOR RATE" shall mean, with respect to any Interest Period occurring
during the term of the Lease, an interest rate per annum equal at all times
during such Interest Period to the quotient of (1) the rate per annum as
determined by Lessor at which deposits of U.S. Dollars in immediately available
and freely transferable funds are offered at 11:00 a.m. (London, England time)
two (2) Business Days before the commencement of such Interest Period to major
banks in the London interbank market for a period of three (3) months and in an
amount equal or comparable to the Capitalized Lessor's Cost, divided by (2) a
number equal to 1.00 minus the aggregate (without duplication) of the rates
(expressed as a decimal fraction) of the LIBOR Reserve Requirements current on
the date three (3) Business Days prior to the first day of the Interest Period.

         "LIBOR RESERVE REQUIREMENTS" shall mean the daily average for the
applicable Interest Period of the maximum rate applicable to Lessor or its
Participants at which reserves (including, without limitation, any supplemental,
marginal and emergency reserves) are imposed during such Interest Period by the
Board of Governors of the Federal Reserve System (or any successor) on
"Eurocurrency liabilities", as defined in such Board's Regulation D (or in
respect of any other category of liabilities that include deposits by reference
to which the interest rates on Eurodollar loans is determined or any category of
extensions of credit or other assets that include loans by non-United States
offices of any lender to United


                                      -3-

States residents), having a term equal to such Interest Period, subject to any
amendments of such reserve requirement by such Board or its successor, taking
into account any transitional adjustments thereto.

         If at any time Lessor or any Participant (or, without duplication, the
bank holding company of which such Participant is a subsidiary) determines that
either adequate and reasonable means do not exist for ascertaining the LIBOR
Rate, or it becomes impractical for Lessor or any Participant to obtain funds to
make or maintain the financing hereunder with interest at the LIBOR Rate, or
Lessor or any Participant reasonably determines that, as a result of changes to
applicable law after the date of execution of the Agreement, or the adoption or
making after such date of any interpretations, directives or regulations
(whether or not having the force of law) by any court, governmental authority or
reserve bank charged with the interpretation or administration thereof, it shall
be or become unlawful or impossible to make, maintain, or fund the transaction
hereunder at the LIBOR Rate, then Lessor promptly shall give notice to Lessee of
such determination and Lessor and Lessee shall negotiate in good faith a
mutually acceptable alternative method of calculating the Interest Rate and
shall execute and deliver such documents as reasonably may be required to
incorporate such alternative method of calculating the Interest Rate in this
Schedule, within thirty (30) days after the date of Lessor's notice to Lessee.
If the parties are unable mutually to agree to such alternative method of
calculating the Interest Rate in a timely fashion, (a) effective on the
commencement of the next succeeding Interest Period or the date that it becomes
impractical for Lessor or any Participant to maintain the financing hereunder
with interest at the LIBOR Rate as aforesaid, as case may be, the Interest Rate
shall become a floating rate equal to the Federal Funds Rate plus sixty (60)
basis points, and (b) on the Rent Payment Date next succeeding the expiration of
such thirty (30) day period Lessee shall purchase all (but not less than all) of
the Equipment described on all Schedules executed pursuant to the Agreement and
shall pay to Lessor, in cash, the purchase price for the Equipment so purchased,
determined as hereinafter provided. (As used herein, "Federal Funds Rate" means
the rate of interest, as reasonably determined by Lessor, paid by or available
to Lessor for the purchase of "federal funds" at the time or times in question
on a daily overnight basis.) The purchase price of the Equipment shall be an
amount equal to the Stipulated Loss Value of such Equipment calculated in
accordance with Annex D as of the date of payment, together with all rent and
other sums then due on such date, plus all taxes and charges upon sale and all
other reasonable and documented expenses incurred by Lessor in connection with
such sale. Upon satisfaction of the conditions specified in this Paragraph,
Lessor will transfer, on an AS IS, WHERE IS BASIS, all of Lessor's interest in
and to the Equipment. Lessor shall not be required to make and may specifically
disclaim any representation or warranty as to the condition of the Equipment and
other matters (except that Lessor shall warrant that it conveyed whatever
interest it received in such Equipment free and clear of any Lien created by
Lessor). Lessor shall execute and deliver to Lessee such Uniform Commercial Code
statements of termination as reasonably may be required in order to terminate
any interest of Lessor in and to the Equipment.

         2. If the Rent Payment Date or any Rent Payment Date is not a Business
Day, the Rent otherwise due on such date shall be payable on the immediately
preceding Business Day.

         3. Lessee shall pay to Lessor, for the account of each Participant,
from time to time the amounts as such Participant may determine to be necessary
to compensate it for any costs which such Participant determines are
attributable to its making or maintaining its interest in the Lease and the
Equipment (the "Interest") or any reduction in any amount receivable by such
Participant in respect of any such Interest (such increases in costs and
reductions in amounts receivable being herein called "Additional Costs"),
resulting from any Regulatory Change (as defined below) which:

            (i) changes the basis of taxation of any amounts payable to Lessor
            for the account of such Participant in respect of such Interest
            (other than taxes imposed on or measured by the overall net income
            of such Participant in respect of the interest by the jurisdiction
            in which such Participant has its principal office or its lending
            office); or


                                       -4-

<PAGE>   17


            (ii) imposes or modifies any reserve, special deposit or similar
            requirements relating to any extensions of credit or other assets
            of, or any deposits with or other liabilities of, such Participant;
            or

            (iii) imposes any other condition affecting this Lease or any
            Interest.

For purposes hereof, "Regulatory Change" shall mean any change after the date of
this Lease in United States federal, state or foreign law or regulations
(including, without limitation, Regulation D of the Board of Governors of the
Federal Reserve System (or any successor), as amended or supplemented from time
to time) or the adoption or making after such date of any interpretation,
directive or request applying to a class of banks including any Participant or
under any United States federal, state or foreign law and whether or not failure
to comply therewith would be unlawful) by any court or governmental or monetary
authority charged with the interpretation or administration thereof.

         Without limiting the effect of the foregoing Paragraph (but without
duplication), Lessee shall pay to Lessor, for the account of each Participant,
from time to time on request such amounts as such Participant may determine to
be necessary to compensate such Participant (or, without duplication, the bank
holding company of which such Participant is a subsidiary) for any costs which
it determines are attributable to the maintenance by such Participant (or any
lending office or such bank holding company), pursuant to any law or regulation
or any interpretation, directive or request (whether or not having the force of
law) of any court or governmental or monetary authority (i) following any
Regulatory Change or (ii) implementing any risk-based capital guideline or
requirement (whether or not having the force of law and whether or not the
failure to comply therewith would be unlawful) heretofore or hereafter issued by
any government or governmental or supervisory authority implementing at the
national level the Basle Accord (including, without limitation, the Final
Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve
System (12 C.F.R. Part 208, Appendix A; 12 C.F.R. Part 225, Appendix A) and the
Final Risk-Based Capital Guidelines of the Office of the Comptroller of the
Currency (12 C.F.R. Part 3, Appendix A)), of capital in respect of such
Participant's Interest (such compensation to include, without limitation, an
amount equal to any reduction of the rate of return on assets or equity of such
Participant (or any lending office or bank holding company) to a level below
that which such Participant (or any lending office or bank holding company)
could have achieved but for such law, regulation, interpretation, directive or
request). For purposes of this Paragraph, "Basle Accord" shall mean the
proposals for risk-based capital framework described by the Basle Committee on
Banking Regulations and Supervisory Practices in its paper entitled
"International Convergence of Capital Measurement and Capital Standards" dated
July 1988, as amended, modified and supplemented and in effect from time to time
or any replacement thereof.

         Each Participant shall notify Lessee of any event occurring after the
date of this Lease that will entitle such Participant to compensation under the
preceding two Paragraphs as promptly as practicable, but in any event within
thirty (30) days, after such Participant obtains actual knowledge thereof;
provided, that (i) if such Participant fails to give such notice within thirty
(30) days after it obtains actual knowledge of such an event, such Participant
shall, with respect to compensation payable pursuant to the preceding two
Paragraphs in respect of any costs resulting from such event, only be entitled
to payment under the referenced Paragraphs for costs incurred from and after the
date thirty (30) days prior to the date that such Participant does give such
notice, and (ii) such Participant will designate a different lending office for
the Interest if such designation will avoid the need for, or reduce the amount
of, such compensation and will not, in the sole opinion of such Participant, be
disadvantageous to such Participant. Each Participant will furnish to Lessee a
certificate setting forth the basis and amount of each request by such
Participant for compensation under the preceding two Paragraphs. Determinations
and allocations by each Participant for purposes of the preceding two Paragraphs
shall be conclusive, absent manifest error.
