                               ANSOFT CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

         The unaudited consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated. In the opinion of management,
all adjustments (consisting only of normal recurring adjustments) necessary for
a fair presentation of financial position and results of operations have been
made. Operating results for interim periods are not necessarily indicative of
results which may be expected for a full year. The information included in this
Form 10-Q should be read in conjunction with Management's Discussion and
Analysis of Financial Condition and Results of Operations and the fiscal year
ended April 30, 1998 consolidated financial statements and notes thereto
included in the Company's annual report on Form 10-K filed with the Commission.

         The preparation of the consolidated financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities, revenues and expenses and disclosure of contingent assets and
liabilities. The estimates and assumptions used in the accompanying consolidated
financial statements are based on management's evaluation of the relevant facts
and circumstances as of the date of the consolidated financial statements.
Actual results may differ from those estimates.

(2) Borrowings

         The Company has available a secured line of credit from a domestic
financial institution at an interest rate equal to LIBOR plus an applicable
margin rate. The line of credit is secured by the marketable securities held
with the institution. As of January 31, 1999, $5.0 million was the outstanding
balance on the line of credit.

(3)  Comprehensive income (loss)

On May 1, 1998, the Company adopted Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income" ("SFAS 130"), which establishes
requirements for disclosure of comprehensive income. The objective of SFAS 130
is to report all changes in equity that result from transactions and economic
events other than transactions with owners. Comprehensive income is the total of
net income and all other non-owner changes in equity. Adoption of SFAS 130 did
not impact the Company's consolidated financial position, results of operations
or cash flows for the nine months ended January 31, 1999 and 1998. The
reconciliation of net income (loss) to comprehensive income (loss) is as follows
(in thousands):

(4) Net income (loss) per share

"Basic earnings (loss) per share" is calculated based upon the weighted average
number of common shares actually outstanding, and "diluted earnings per share"
is calculated based upon the weighted average number of common shares
outstanding and other potential common shares if they are dilutive.

         The following is a reconciliation of the numerators and denominators of
the basic and diluted EPS computations for the periods presented:

that involve substantial risks and uncertainties. When used herein, the words
"anticipate," "plan," "believe," "estimate," "expect" and similar expressions as
they relate to the Company or its management are intended to identify such
forward-looking statements. The Company's actual results, performance or
achievements could differ materially from the results expressed in, or implied
by, these forward-looking statements. Factors that could cause or contribute to
such differences include those discussed in "Risk Factors" section included in
the Company's report on Form 10-K for the fiscal year ended April 30, 1998.

Overview

         Ansoft Corporation ("Ansoft" or the "Company") develops, markets and
supports electronic design automation ("EDA") software based on fundamental
electromagnetic principles. The Company's products are used by design engineers
in a wide range of industries, including the rapidly evolving wireless
communications and RF markets as well as the semiconductor, computer, automotive
and consumer electronics industries. The Company's software is used in the
design of high performance electrical devices and systems, such as cellular
phones, communications systems, computer circuit boards and motors.

         License revenue consists principally of revenue from the licensing of
the Company's software and is generally recognized when the software has been
shipped and there are no significant remaining obligations. Service revenue
consists of maintenance fees for providing system updates, user documentation
and technical support for software products, and is recognized ratably over the
term of the maintenance agreement. Other revenue consists primarily of revenue
earned on development contracts with government-sponsored entities. Revenue
under these arrangements is recognized as the service is performed.

         In accordance with Statement of Financial Accounting Standards (SFAS)
No. 86, the Company has evaluated the establishment of technological feasibility
of its various products during the development phase. Due to the dynamic changes
in the market, the Company has concluded that it cannot determine, with any
reasonable degree of accuracy, technological feasibility until the development
phase of the project is nearly complete. The time period during which costs
could be capitalized from the point of reaching technological feasibility until
the time of general product release is generally very short and, consequently,

the amounts that could be capitalized pursuant to SFAS No. 86 are not material
to the Company's financial position or results of operations. Therefore, the
Company charges all research and development expenses to operations in the
period incurred.

         Effective July 24, 1996, April 9, 1997 and August 8, 1997, the Company
acquired the Electronic Business Unit (the "EBU") of The MacNeal Schwendler
Company ("MSC"), Compact Software Inc. ("Compact"), and Boulder Microwave
Technologies, Inc. ("Boulder"), respectively. The cost of these acquisitions has
been allocated on the basis of the estimated fair value of the assets acquired
and the liabilities assumed. The acquisitions have been accounted for as
purchases, and their respective financial results have been included in the
accompanying consolidated financial statements since the date of their
respective acquisitions.

Comparison of The Three and Nine Months Ended January 31, 1999 and 1998

         Revenue. Total revenue in the three-month period ended January 31, 1999
decreased 11% to $6.1 million from $6.8 million in the comparable period of the
preceding fiscal year. Total revenue in the nine-month period ended January 31,
1999 decreased 9% to $16.7 million from $18.5 million in the comparable period
of the preceding fiscal year. The decrease in total revenue is primarily
attributable to lower sales in the Asia-Pacific region and a decrease in service
revenue due to the completion of a research and development cost sharing
contract during 1998. License revenue during the three-month period ended
January 31, 1999 decreased 5% to $4.8 million from $5.0 million during the
comparable period in the prior fiscal year. License revenue during the
nine-month period ended January 31, 1999 decreased 14% to $12.0 million from
$13.9 million during the comparable period in the prior fiscal year.

         International revenue accounted for 56% and 52% of the Company's total
product revenue in the three-month period ended January 31, 1999 and 1998,
respectively. International revenue accounted for 53% and 50% of the Company's
total product revenue in the nine-month period ended January 31, 1999 and 1998,
respectively.

         Sales and marketing expenses. Sales and marketing expenses consist of
salaries, commissions paid to internal sales and marketing personnel and
international distributors, promotional costs and related operating expenses.
Sales and marketing expenses increased by 36% to $4.3 million in the three-month
period ended January 31, 1999, as compared to $3.1 million in the same period in
the previous fiscal year. Sales and marketing expenses increased by 47% to $12.6
million in the nine-month period ended January 31, 1999, as compared to $8.6
million in the same period in the previous fiscal year. The increase is
attributable to an increase in the Company's sales force as a result of the
acquisitions as well as increased marketing efforts, including advertising in
trade publications and increased participation in industry trade shows. Sales
and marketing expenses represented 70% and 46% of total revenue in the
three-month period ended January 31, 1999 and 1998, respectively. Sales and
marketing expenses represented 75% and 46% of total revenue in the nine-month
period ended January 31, 1999 and 1998, respectively. The Company anticipates
that sales and marketing expenses will increase in absolute dollars in future
periods.

         Research and development expenses. Research and development expenses
include all costs associated with the development of new products and
enhancements to existing products. Research and development expenses for the
three-month period ended January 31, 1999 increased 3% to $2.0 million, as
compared to the same period in the previous fiscal year. Research and
development expenses for the nine-month period ended January 31, 1999 increased
16% to $6.2 million, as compared to $5.4 million for the same period in the
previous fiscal year. The increase is due to increased research and development
personnel primarily as a result of the acquisitions. Research and development
expenses represented 33% and 29% of total revenue in the three-month period
ended January 31, 1999 and 1998, respectively. Research and development expenses
represented 37% and 29% of total revenue in the nine-month period ended January
31, 1999 and 1998, respectively. The Company anticipates that research and
development expenses will increase in absolute dollars in future periods.

         General and administrative expenses. General and administrative
expenses for the three-month period ended January 31, 1999 increased 18% to
$706,000, as compared to $600,000 for the same period in the previous fiscal
year. General and administrative expenses for the nine-month period ended
January 31, 1999 increased 22% to $2.0 million, as compared to $1.7 million for
the same period in the previous fiscal year. The increase is due to additional
costs required to support the increase in operations. General and administrative
expenses represented 12% and 9% of total revenue in the three-month period ended
January 31, 1999 and 1998, respectively. General and administrative expenses
represented 12% and 9% of total revenue in the nine-month period ended January
31, 1999 and 1998, respectively. The Company anticipates that general and
administrative expenses will increase in absolute dollars in future periods.

         Amortization expense. Amortization expense for the three-month period
ended January 31, 1999 increased to $434,000, as compared to $395,000 for the
same period in the previous fiscal year. Amortization expense for the nine-month
period ended January 31, 1999 increased to $1.3 million, as compared to $1.1
million for the same period in the previous fiscal year. The increase is due to
the amortization of the additional intangible assets acquired during fiscal 1998
and fiscal 1999.

         Other income. Other income for the three-month period ended January 31,
1999 increased to $404,000, compared to $108,000 for the same period in the
previous fiscal year. Other income increased to $1.2 million for the nine-month
period ended January 31, 1999, compared to $295,000 for the same period in the
previous fiscal year. Other income increased due to the higher net investment
balance made available from the proceeds from the public offering of 2.3 million
shares in March of 1998.

         Income taxes. In the three and nine-month period ended January 31,
1999, the Company recorded a net income tax benefit of $290,000 and $1.2
million, respectively, resulting from the partial recognition of deferred tax
assets in accordance with the Financial Accounting Standards Board's SFAS No.
109, "Accounting for Income Taxes." Valuation allowances are established when
necessary to reduce deferred tax assets to the amounts expected to be realized.

         In June, 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities". The Company
does not expect this pronouncement to impact the consolidated financial
statements because the Company has not entered into derivative or hedging
transactions.

Liquidity and Capital Resources

         As of January 31, 1999, the Company had $1.8 million in cash and cash
equivalents and working capital of $19.7 million. Net cash provided by (used in)
operating activities was $(3.0) million and $180,000 in the nine months ended
January 31, 1999 and 1998, respectively. Net cash provided by (used in)
investing activities was $(18.3) million and $3.2 million in the nine months
ended January 31, 1999 and 1998, respectively. Capital expenditures, consisting
primarily of purchases of computer equipment, were $921,000 and $955,000 in the
nine months ended January 31, 1999 and 1998, respectively. Net cash provided by
financing activities includes cash proceeds of $5.0 million from a new line of
credit in the nine months ended January 31, 1999. During the nine months ended
January 31, 1998, the Company repaid $2.9 million on its line of credit with a
financial institution.

YEAR 2000 ISSUES

         The Company has recently evaluated the products the Company currently
supports to determine if they are Year 2000 ready. Most of the Company's
products do not rely on knowledge of the date (date-sensitive data) for
performance or functionality. The Company's products only use date-sensitive
data with respect to the licensing of the Company's products.

                  State Of Readiness. The results of this evaluation revealed
that most of the Company's supported products are Year 2000 ready. The Company
plans to offer patches or upgrades to the supported products currently not Year
2000 ready.

         During 1998, an evaluation has also been done to the Company's internal
support systems to determine if they are Year 2000 ready to support the
Company's operations beyond the year 2000. The Company currently uses third
party software systems and applications, some of which are not Year 2000 ready.
The Company has the intention to stop using these software products or upgrade
or replace them as part of the Company's growth plans.



                                     Page 9


<PAGE>   12




         Although the Company's intention is to replace or upgrade these systems
prior to June 30, 1999, the work may be extended to December 31, 1999. The
failure by the Company to complete such work prior to December 31, 1999 could
have a material adverse effect on the Company's business, financial condition
and operations.

         Costs. The Company does not have a project tracking system that tracks
the cost and time that its own internal employees spend on the Year 2000
project. Based on the Company's assessment, the cost incurred to date has not
had a material impact to the Company's results of operations. The Company
expects that costs directly related to Year 2000 in excess of normal upgrade and
maintenance costs would not exceed approximately $100,000 for both costs
incurred to date and future costs. However, there is no assurance that the costs
may not exceed this amount.

         Risks. The Company is requesting its vendors to provide Year 2000
compliance certificates for all its internal support systems. However, the
Company only intends to perform testing on its critical internal support
systems. Inoperability related to Year 2000 problems of internal systems that
are certified Year 2000 ready by the vendor and not tested by the Company could
have an adverse impact to the Company's operational efficiency.

         The patches or upgrades provided by the Company as the remedies to make
its products Year 2000 ready may not be accepted by the customer, which could
have an adverse impact on the Company's business.

         The Company believes that the purchasing patterns of customers and
potential customers may be affected by Year 2000 issues as companies expend
significant resources to correct or patch their current software systems for
Year 2000 readiness. These expenditures may result in reduced funds available to
purchase software products such as those offered by the Company, which could
result in a material adverse effect on the Company's business, financial
condition and results of operation. In addition, the Company does not have any
meaningful data as to the state of its customers' Year 2000 readiness.

         Contingency Plans. The Company does not presently have a contingency
plan for handling Year 2000 problems that are not detected and corrected prior
to their occurrences. Upon completion of testing and implementation activities,
the Company will be able to assess the areas requiring contingency planning and
expects to develop appropriate planning at that time. Any failure of the Company
to address any unforeseen Year 2000 problems could adversely affect the
Company's business, financial condition and results of operations.

conditions hereof and relying upon the representations and warranties herein set
forth, that the Borrower shall have the right to borrow, repay and reborrow from
the date hereof until the Revolving Credit Termination Date a principal amount
which shall not exceed the lesser of (i) $10,000,000 in the aggregate at any one
time outstanding and (ii) the Marketable Securities Value.

2.1b VOLUNTARY REDUCTIONS OF REVOLVING CREDIT COMMITMENT; MANDATORY AND 
VOLUNTARY PRINCIPAL PAYMENTS.

         (i) VOLUNTARY REDUCTIONS. Upon two (2) Business Days' notice to the
Lender, the Borrower may from time to time voluntarily permanently reduce the
Revolving Credit Commitment. Each voluntary reduction shall be in a minimum
amount of $500,000. The portion of the Revolving Credit Commitment so terminated

reduction, the Borrower shall make a payment



                                     - 13 -
<PAGE>   15


of the outstanding Revolving Credit Advances equal to the excess, if any, of (A)
the aggregate principal amount of the outstanding Revolving Credit Advances over
(B) the Revolving Credit Commitment, as so reduced. All such reductions shall be
without penalty or premium.

         (ii) MANDATORY REDUCTIONS OF PRINCIPAL. In the event that at any time
the outstanding Revolving Credit Advances exceed the Marketable Securities
Value, the Borrower shall immediately reduce the outstanding Revolving Credit
Advances by an amount necessary so that the aggregate amount of all outstanding
Revolving Credit Advances is once again equal to or less than the Marketable
Securities Value.

         (iii) ADDITIONAL PAYMENTS. Any payments or prepayments of Revolving
Credit Advances shall be accompanied by all accrued and unpaid interest thereon
and all other amounts due hereunder with respect to such prepayment.

2.1c AMOUNT OF REVOLVING CREDIT ADVANCES. Each Revolving Credit Advance shall be
in a minimum amount of $100,000; provided, however, that if the entire amount of
Revolving Credit Advances available to the Borrower is less than $100,000, then
such Revolving Credit Advance shall be for such entire amount.

2.1d REQUESTS FOR REVOLVING CREDIT ADVANCES. Each request for a Revolving Credit
Advance shall be made to the Lender orally or in writing pursuant to the
execution and delivery by the Borrower to the Lender of a Loan Request, by an
Authorized Officer of the Borrower, by 10:00 A.M. (Eastern time):

         (i) on the date (which must be a Business Day) of the proposed
Revolving Credit Advance if the Revolving Credit Advance is initially to bear
interest at the Base Rate Option,

         (ii) by 10:00 A.M. (Eastern time) on the date (which must be a Business
Day) which is at least two (2) Business Days prior to the proposed disbursement
with respect to Loans made in Dollars if the Revolving Credit Advance or any
part thereof is to initially bear interest at the LIBOR Rate Option, or

         (iii) by 10:00 A.M. (Eastern time) at least two (2) Business Days prior
to the proposed Revolving Credit Advance with respect to Loans funded in an
Optional Currency (which Loans must bear interest at the LIBOR Rate Option),

in each case specifying the Dollar or Dollar Equivalent (if applicable) amount
thereof, selecting the Interest Rate Option therefor pursuant to Section 2.2
hereof, and, if appropriate, selecting the LIBOR Rate Interest Period therefor
and for Loans to be funded in an Optional Currency, the currency in which the
disbursement is to be funded. Any oral request for a Revolving Credit Advance
shall be followed immediately by the Borrower's written Loan Request. A request
from the Borrower pursuant to this Section 2.1d with respect to a Revolving
Credit Advance or any part thereof which is initially to bear interest at the
LIBOR Rate Option, shall irrevocably commit the Borrower to accept such
disbursement on the date specified in such request. The Lender shall make each
Revolving Credit Advance available to the Borrower in immediately available
funds at the principal office of the Lender on the date of such Revolving Credit
Advance by depositing the proceeds of such Loan in the Borrower's demand deposit
account maintained with the Lender, absent written instructions from the
Borrower to the contrary.

Termination Date the entire outstanding principal balance of the Revolving
Credit Advances, plus all accrued and unpaid interest thereon, any unpaid Fees

as the case may be, and in accordance with the provisions of Section 2.2d.

         (ii) LIBOR RATE OPTION. Interest under this Interest Rate Option shall

interest established pursuant to the preceding sentence of this paragraph (ii)
for each LIBOR Rate Portion shall be adjusted from time to time in accordance
with the provisions of Section 2.2d.

during the continuation thereof, (i) the Base Rate Portion shall bear interest
at a rate per annum which shall be two hundred (200) basis points (2%) above the
Base Rate otherwise in effect during such period, and (ii) all LIBOR Rate
Portions shall bear interest (A) until the end of the then current LIBOR Rate
Interest Period for each such LIBOR Rate Portion, at a rate per annum which
shall be two hundred (200) basis points (2%) above the sum of (x) the LIBOR Rate
and (y) the Applicable LIBOR Rate Margin otherwise in effect during such period,
and (B) at the end of the then current LIBOR Rate Interest Period for each such



                                     - 15 -
<PAGE>   17


LIBOR Rate Portion, such LIBOR Rate Portions shall automatically be converted to
the Base Rate Portion, and thereafter the interest rate shall be calculated in
accordance with item (i) of this Section 2.2d. The foregoing adjustments to the
interest rates in effect hereunder shall be effective whether or not judgment
has been entered on the Revolving Credit Note.

2.2e  INTEREST PERIODS; LIMITATIONS ON ELECTIONS.

         (i) At any time when the Borrower shall select, convert to or renew the

         (B) any LIBOR Rate Interest Period which begins on the last day of a
calendar month or on a day for which there is no numerically corresponding day
in the subsequent calendar month during which such LIBOR Rate Interest Period is

2.2f ELECTION, RENEWAL OR CONVERSION OF INTEREST RATE OPTIONS. Elections or
renewals of, or conversions to, the Base Rate Option shall continue in effect
until converted or renewed as hereinafter provided. Elections or renewals of, or
conversions to, the LIBOR Rate Option shall expire as to each LIBOR Rate Portion
at the expiration of the applicable LIBOR Rate Interest Period. At any time with
respect to the Base Rate Portion or at the expiration of the applicable LIBOR
Rate Interest Period with respect to any LIBOR Rate Portion, the Borrower may
cause (subject to Subsection 2.2e) all or any part of the principal amount of
such Portion to be converted to, or to be renewed under, the LIBOR Rate Option
by notice to the Lender as hereinafter provided. Such notice (i) shall be
irrevocable, (ii) shall be given not later than 12:00 noon (Eastern time) in the
case of a conversion to or renewal of, either in whole or in part, the LIBOR
Rate Option, not less than two (2) Business Days prior to the proposed effective

         (B) the new LIBOR Rate Interest Period(s) selected; and

         (C) with respect to each such LIBOR Rate Interest Period, the aggregate
principal amount of the corresponding LIBOR Rate Portion.

At the expiration of each LIBOR Rate Interest Period, any part (including the
whole) of the principal amount of the corresponding LIBOR Rate Portion as to
which no notice of conversion or renewal has been received shall automatically
be converted to the Base Rate Option. The Lender shall promptly notify the
Borrower of any such automatic conversion.

2.2g NOTIFICATION OF ELECTION OF AN INTEREST RATE OPTION. An Authorized Officer
of the Borrower shall notify the Lender of each election of an Interest Rate
Option, each conversion from one Interest Rate Option to another, the amount of
the Loans then outstanding to be allocated to each Interest Rate Option and,
where relevant, the LIBOR Rate Interest Periods as provided for in this
Agreement. Any such communication may be oral or written and if oral it shall be
followed promptly by written confirmation of such Interest Rate Option election
executed by an Authorized Officer of the Borrower.

2.2h LAWFUL INTEREST RATES INTENDED. In no event whatsoever shall the interest
rates charged hereunder exceed the highest rate permissible under any law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto. In the event that such a court determines that the Lender has
received interest hereunder in excess of the highest applicable rate, the Lender

to the Lender.

of election hereunder shall be followed immediately by written confirmation of
such prepayment election executed by an Authorized Officer of the Borrower.

2.4c, the Borrower, upon oral or written notice to the Lender by an Authorized
Officer of the Borrower given at least three (3) Business Days prior to the
proposed date for repayment, may prepay all or any part of such LIBOR Rate
Portion. If such LIBOR Rate Portion is prepaid on the last day of the LIBOR Rate
Interest Period applicable thereto, such prepayment shall be without premium or
penalty. If the Borrower prepays a LIBOR Rate Portion other than on the last day
of the LIBOR Rate Interest Period applicable thereto, the Borrower agrees to
pay, in addition to the other amounts set forth in this Section 2.3b, such
additional amounts as may be necessary to compensate the Lender for any loss and
any direct or indirect costs, including the costs of reemployment of funds
prepaid at rates lower than the cost to the Lender of such funds. Such losses
and costs shall be specified in writing to the Borrower by the Lender (and such
specifications shall set forth in reasonable detail the calculation of such
losses and costs) and such specifications shall, absent manifest error, be
binding and conclusive on the Borrower. Such prepayment shall include the then
outstanding principal amount of the LIBOR Rate Portion being prepaid together
with accrued interest, fees and other amounts then due and payable on the amount
prepaid, to the day of such prepayment. Except as provided in this Section 2.3b,
there shall be no voluntary prepayment of any LIBOR Rate Portion.

2.3c ALLOCATION OF REPAYMENTS OF PRINCIPAL. Any voluntary prepayment pursuant to
this Section 2.3 shall be applied first to the repayment of any LIBOR Rate
Portion of the Loans for which its associated LIBOR Rate Interest Period expires
on the date of such payment; second, to the reduction of the Base Rate Portion
of the Loans; and third, to the reduction of such LIBOR Rate Portions of the
Loans as directed by the Borrower, and if the Borrower fails to give such
directions, or if a Default or Event of 




                                     - 17 -
<PAGE>   19



Default has occurred and is continuing, to the reduction of such LIBOR Rate
Portions of the Loans as the Lender may select in its sole and absolute
discretion. Any reduction in any LIBOR Rate Portion on a date other than the
date on which its associated LIBOR Rate Interest Period expires may result in a
funding loss for which the Borrower will owe the Lender an indemnity payment
pursuant to Section 2.4 hereof.

2.4. YIELD PROTECTION.

2.4a ILLEGALITY. If any change subsequent to the Closing Date in any Law or in
the interpretation or application thereof by any Governmental Authority or in
the compliance with any guideline or request from any Governmental Authority,
shall make it unlawful for the Lender to maintain or give effect to its
obligations as contemplated under the Revolving Credit Commitment, the Lender
shall notify the Borrower in writing of its determination of such unlawfulness
and an explanation thereof. Thereafter, the Lender's obligation to make
available any further Loans hereunder shall forthwith be cancelled and the
Borrower, within thirty (30) days, or within such longer period as may be
allowed by Law, if any, shall repay to the Lender the outstanding principal
amount of all Loans, together with interest thereon to the date of repayment and
all other outstanding Fees and other Obligations, if any, due as of the date of
termination; provided, however, that the Lender's obligations which are lawful,
if severable from those which are unlawful, shall continue, and with respect to
those obligations, this Agreement shall not terminate.

2.4b CHANGE IN LAW. If any Law issued after the Closing Date (including, without
limitation, Regulation D, or if any change on or after the Closing Date in any
Law (including, without limitation, Regulation D) or in the interpretation
thereof by any Governmental Authority charged with the administration thereof,
shall

         (i) subject the Lender to any tax, levy, impost, charge, fee, duty,
deduction or withholding of any kind under this Agreement (other than any tax
imposed or based upon the income of the Lender and payable to any Governmental
Authority in the United States of America, any state or any municipality
thereof); or

         (ii) change the basis of taxation of the Lender with respect to
payments of principal or interest or other amounts due under this Agreement
(other than any change which affects, and only to the extent that it affects,
the taxation by the United States, any state or any municipality thereof based
upon the income of the Lender); or

         (iii) impose, modify or deem applicable any reserve, special deposit or
similar requirements against assets held by the Lender with respect to this
Agreement (other than such requirements which result solely from a change in the
credit quality of the Borrower or which are included in the determination of the
applicable rate of interest hereunder); or

         (iv) impose upon the Lender any other obligation or condition with
respect to this Agreement, and the result of any of the foregoing is to increase
the cost to the Lender, to decrease the yield to the Lender with respect to the
Loans, to reduce the income receivable by the Lender or to impose any expenses
upon the Lender with respect to the Loans by an amount which the Lender
reasonably deems material, then and in any such case:

         (A) the Lender shall promptly notify the Borrower of the happening of
such event;

         (B) the Borrower shall pay to the Lender, within five (5) Business Days
of written demand, such amount as will compensate the Lender for such additional
cost or reduced amount, calculated from the date of the notification by the
Lender; and




                                     - 18 -
<PAGE>   20


         (C) the Borrower may pay to the Lender the affected Loan in full
without the payment of any additional amount other than on account of the
Lender's out-of-pocket losses (including funding losses, if any, as provided in
Section 2.4c below) not otherwise provided for in subparagraph (B) immediately
above.

The Lender shall present to the Borrower a certificate setting forth such
increased cost or reduced amount. Such certificate shall set forth in reasonable
detail the calculation of the amount due and the Lender's reasons for invoking
the provisions of this Section 2.4b. Such certificate shall be evidence of the
amount due thereunder except in the case of manifest error in computation.

2.4c INDEMNIFICATION. The Borrower agrees to indemnify the Lender, on demand,
against any loss or expense (including loss of profit) which the Lender may
sustain or incur in liquidating or employing deposits from third parties
acquired to effect, fund or maintain such LIBOR Rate Portions or any part
thereof as a consequence of (i) the failure of the Borrower to make a payment on
the due date thereof, (ii) the failure of the Borrower to borrow under, convert
to or renew under the LIBOR Rate Option on the proposed effective date of such
borrowing, conversion or renewal, or (iii) the payment, prepayment or conversion
by the Borrower of any LIBOR Rate Portions for any reason on a day other than
the last day of the applicable LIBOR Rate Interest Period. The Lender's
determination of an amount payable under this Subsection 2.4c shall be evidence
of such amount absent manifest error.

2.5  SPECIAL PROVISIONS RELATING TO THE LIBOR RATE OPTION.

2.5a LIBOR RATE UNASCERTAINABLE. In the event that on any date on which a LIBOR
Rate Option would otherwise be set, the Lender shall have determined (which
determination shall be final and conclusive) that, by reason of circumstances
affecting the London interbank market, adequate, reasonable means do not exist
for ascertaining the LIBOR Rate, the Lender shall give prompt notice of such
determination to the Borrower. Until the Lender notifies the Borrower that the
circumstances giving rise to such determination no longer exist (which notice
shall be given promptly following receipt of knowledge thereof by the Lender),
the right of the Borrower to borrow under, convert to or renew the LIBOR Rate
Option shall be suspended. Any notice of borrowing under, conversion to or
renewal of the LIBOR Rate Option which was to become effective during the period
of such suspension shall be treated as a request to borrow under, convert to or
renew the Base Rate Option with respect to the principal amount therein
specified.

2.5b INABILITY TO OFFER LIBOR RATE. In the event that the Lender shall
determine, in its sole discretion, that it is unable to obtain deposits in the
London interbank market in sufficient amounts and with maturities related to
such LIBOR Rate Portions which would enable the Lender to fund such LIBOR Rate
Portions, then the Lender shall notify the Borrower that the right of the
Borrower to borrow under, convert to or renew the LIBOR Rate Option, shall be
suspended. Such notice shall set forth in reasonable detail the Lender's reasons
for invoking the provisions of this Section 2.5b. Following notification of the
suspension of the LIBOR Rate Option with respect to the Lender, the Borrower
agrees to negotiate with the Lender for a modified or alternative fixed rate of
interest, which will allow the Lender to realize its anticipated and
bargained-for yield. In the event that the Borrower and the Lender cannot agree
on a modified or alternative fixed rate of interest, any notice of borrowing
under, conversion to or renewal of the LIBOR Rate Option which was to become
effective during the period of suspension shall be treated as a request to
borrow under, convert to or renew the Base Rate Option with respect to the
principal amount specified therein attributable to the Lender.

2.5c ILLEGALITY. If the Lender shall determine in good faith (which
determination shall be final and conclusive) that compliance with any Law
(whether or not having the force of law) or the interpretation or application
thereof by any Governmental Authority, has made it unlawful for the Lender to
make or maintain the Loans under the LIBOR Rate Option, the Lender shall give
notice of such determination to the Borrower, which notice shall set forth in
reasonable detail the Lender's reasons for invoking the provisions of this
Section 2.5c. Notwithstanding any provision of this Agreement to the contrary,
unless 




                                     - 19 -
<PAGE>   21


and until the Lender shall have given notice to the Borrower that the
circumstances giving rise to such determination no longer apply (which notice
shall be given promptly following receipt of knowledge thereof by the Lender):

         (i) with respect to any LIBOR Rate Interest Periods thereafter
commencing, interest with respect to an amount equal to the corresponding LIBOR
Rate Portion shall be computed and payable under the Base Rate Option; and

         (ii) on such date, if any, as shall be required by law, an amount equal
to any LIBOR Rate Portion, as the case may be, then outstanding shall be
automatically converted to the Base Rate Option and the Borrower shall pay to
the Lender the accrued and unpaid interest on such amounts to (but not
including) such conversion date.

The Borrower shall pay the Lender any additional amounts reasonably necessary to
compensate the Lender for any costs incurred by the Lender as a result of any
conversion pursuant to clause (ii) above which occurs on a day other than the
last day of the relevant LIBOR Rate Interest Period, including, but not limited
to, any interest or fees payable by the Lender to lenders of funds obtained by
it to loan or maintain the lending of the Loans so converted. The Lender shall
furnish to the Borrower a certificate as to the amount necessary to compensate
it for such costs, which certificate shall set forth in reasonable detail the
calculation of the amount due. Such certificate shall constitute conclusive
evidence of the amount due thereunder absent any manifest error in computation.
The Borrower shall pay such amount to the Lender, as additional consideration
hereunder, within ten (10) days of the Borrower's receipt of such certificate.

2.5d CALCULATION OF INTEREST AND REVOLVING CREDIT COMMITMENT FEE. Interest and
the Revolving Credit Commitment Fee shall be calculated on the basis of the
actual number of days elapsed, using a year of 360 days.

2.6 CAPITAL ADEQUACY. If (i) any adoption of or any change in or in the
interpretation of any Law, (ii) compliance with any Law of any Governmental
Authority exercising control over banks or financial institutions generally or
any court (whether or not having the force of law), or (iii) any change in the
force or effectiveness of the regulations set forth at 12 C.F.R. Part 3
(Appendix A), 12 C.F.R. Part 208 (Appendix A), 12 C.F.R. Part 225 (Appendix A)
or 12 C.F.R. Part 325 (Appendix A) affects or would affect the amount of capital
required or expected to be maintained by the Lender (a "CAPITAL ADEQUACY
EVENT"), and the result of such Capital Adequacy Event is to reduce the rate of
return on the Lender's capital as a consequence thereof to a level below that
which the Lender could have achieved but for such Capital Adequacy Event, taking
into consideration the Lender's policies with respect to capital adequacy, by an
amount which the Lender deems to be material, the Lender shall deliver to the
Borrower a statement of the amount necessary to compensate the Lender for the
reduction in the rate of return on its capital attributable to the Loans and the
commitment hereunder (the "CAPITAL COMPENSATION AMOUNT"). The Lender shall
determine the Capital Compensation Amount in good faith, using reasonable
attribution and averaging methods. Such amount shall be due and payable by the
Borrower to the Lender ten (10) Business Days after such notice is given by the
Lender.

2.7  UTILIZATION OF COMMITMENTS IN OPTIONAL CURRENCIES.

2.7a PERIODIC COMPUTATIONS OF DOLLAR EQUIVALENT AMOUNTS OF LOANS OUTSTANDING.
The Lender will determine the Dollar Equivalent amount of (i) proposed Loans to
be denominated in an Optional Currency as of the date of the requested
disbursement, (ii) outstanding Loans denominated in an Optional Currency as of
the last Business Day of each month, and (iii) outstanding Loans denominated in
an Optional Currency as of the end of each Interest Period (each such date under
clauses (i) through (iii) a "COMPUTATION DATE").




                                     - 20 -
<PAGE>   22



2.7b NOTICE FROM LENDER THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO FUND NEW
LOANS. The Lender shall be under no obligation to make the Loans requested by
the Borrower which are denominated in an Optional Currency if the Lender
notifies the Borrower by 12:00 noon (Eastern time) one (1) Business Day prior to
the borrowing or issuance date for such Loan that the Lender cannot provide such
Loan in such Optional Currency. If the Borrower receives a notice described in
the preceding sentence, the Borrower may, by notice to the Lender not later than
5:00 P.M. (Eastern time) one (1) Business Day prior to the borrowing or issuance
date for such Loan, withdraw the Loan Request for such Loan. If the Borrower
withdraws such Loan Request, the Lender shall not make such Loan. If the
Borrower does not withdraw such Loan Request before such time, (i) the Borrower
shall be deemed to have requested that the Loans referred to in its Loan Request
shall be made in Dollars in an amount equal to the Dollar Equivalent amount of
such Loans.

2.7c NOTICES FROM LENDER THAT OPTIONAL CURRENCIES ARE UNAVAILABLE TO FUND
RENEWALS OF LIBOR RATE OPTION LOANS. If the Borrower delivers a Loan Request
requesting that the Lender renew the LIBOR Rate Option with respect to an
outstanding Portion of Loans denominated in an Optional Currency, the Lender
shall be under no obligation to renew such LIBOR Rate Option if the Lender
delivers to the Borrower notice by 12:00 noon (Eastern time) one (1) Business
Day prior to effective date of such renewal that the Lender cannot continue to
provide Loans in such Optional Currency. If the Lender shall have so notified
the Borrower that any such continuation of Loans denominated in an Optional
Currency issued in an Optional Currency is not then available, any notice of
renewal with respect thereto shall be deemed withdrawn, and such Loans
denominated in an Optional Currency shall be re-denominated into Base Rate Loans
in Dollars with effect from the last day of the Interest Period with respect to
any such Loans denominated in an Optional Currency. The Lender will promptly
notify the Borrower of any such re-denomination, and in such notice, the Lender
will state the aggregate Dollar Equivalent amount of the re-denominated Loans
denominated in an Optional Currency issued in an Optional Currency as of the
Computation Date with respect thereto.

2.7d REQUESTS FOR ADDITIONAL OPTIONAL CURRENCIES. The Borrower may deliver to
the Lender a written request that Loans hereunder also be permitted to be made
in any other lawful currency (other than Dollars), in addition to the currencies
specifically identified in the definition of "Optional Currency"; provided that
such currency must be freely traded in the offshore interbank foreign exchange
markets, freely transferable, freely convertible into Dollars, available to the
Lender in the applicable interbank market, meet the definition of "Optional
Currency", as defined herein, and otherwise be acceptable to the Lender in its
discretion. The Lender may grant or accept such request in its sole discretion.
The Lender will promptly notify the Borrower of its acceptance or rejection of
the Borrower's request.

2.7e OPTIONAL CURRENCY FEE. The Borrower shall pay to the Lender in Dollars the
Lender's fees which are then in effect with respect to Loans denominated in an
Optional Currency as the Lender may generally charge or incur in connection with
the funding, maintenance, modification (if any), negotiation, and administration
of Loans denominated in an Optional Currency.

2.7f CURRENCY REPAYMENTS. Notwithstanding anything contained herein to the
contrary, the entire amount of principal of and interest on any Loan made in an
Optional Currency shall be repaid in the same Optional Currency in which such
Loan was made, provided, however, that if it is impossible or illegal for the
Borrower to effect payment of a Loan in the Optional Currency in which such Loan
was made, or if the Borrower defaults in its obligation to do so, the Lender may
at its option permit such payment to be made (i) at and to a different location,
subsidiary, affiliate or correspondent of the Lender, or (ii) in the Equivalent
Amount of Dollars or (iii) in an Equivalent Amount of such other currency
(freely convertible into Dollars) as the Lender may solely at its option
designate. Upon any events described in items (i) through (iii) of the preceding
sentence, the Borrower shall make such payment and the Borrower agrees to hold
the Lender harmless from and against any loss incurred by the Lender arising
from the cost to the Lender of any premium, any costs of exchange, the cost of
hedging and covering the Optional Currency in which such Loan was originally
made, and from any change in the value of Dollars, or such other currency, in
relation to the Optional Currency that was due and owing. Such loss shall be
calculated for the period 




                                     - 21 -
<PAGE>   23


commencing with the first day of the Interest Period for such Loan and
continuing through the date of payment thereof. Without prejudice to the
survival of any other agreement of the Borrower hereunder, the Borrower's
obligations under this Section 2.7f shall survive termination of this Agreement.

2.7g OPTIONAL CURRENCY AMOUNTS. Notwithstanding anything contained herein to the
contrary, the Lender may, with respect to notices by the Borrower for Loans in
an Optional Currency or voluntary prepayments of less than the full amount of an
Optional Currency Revolving Credit Advance, engage in reasonable rounding of the
Optional Currency amounts requested to be loaned or repaid; and, in such event,
the Lender shall promptly notify the Borrower of such rounded amounts and the
Borrower's request or notice shall thereby be deemed to reflect such rounded
amounts.

2.7h CURRENCY FLUCTUATIONS. If on any Computation Date the sum of the Dollar
Equivalent of all Loans is greater than the Revolving Credit Commitment, as a
result of a change in exchange rates between one or more Optional Currencies and
Dollars, then the Lender shall notify the Borrower of the same. Within two (2)
Business Days after receiving such notice, the Borrower shall pay or prepay
(subject to the Borrower's indemnity obligations under this Agreement) Loans
denominated in an Optional Currency issued in an Optional Currency in amounts
such that the sum of the Dollar Equivalent of all Loans does not exceed the
Revolving Credit Commitment, all after giving effect to such payments or
prepayments.

2.7i INTERBANK MARKET PRESUMPTION. For all purposes of this Agreement and the
Revolving Credit Note with respect to any aspects of the LIBOR Rate, any Loan
under the LIBOR Rate Option or any Optional Currency, the Lender and the Lender
shall be presumed to have obtained rates, funding, currencies, deposits, and the
like in the applicable interbank market regardless whether it did so or not; and
the Lender's determination of amounts payable under, and actions required or
authorized by this Agreement shall be calculated, at the Lender's option, as
though the Lender funded each Portion of Loans under the LIBOR Rate Option
through the purchase of deposits of the types and maturities corresponding to
the deposits used as a reference in accordance with the terms hereof in
determining the LIBOR Rate applicable to such Loans, whether in fact that is the
case.

2.7j JUDGMENT CURRENCY.

         (i) CURRENCY CONVERSION PROCEDURES FOR JUDGMENTS. If for the purposes
of obtaining judgment in any court it is necessary to convert a sum due
hereunder or under a Revolving Credit Note in any currency (the "ORIGINAL
CURRENCY") into another currency (the "OTHER CURRENCY"), the parties hereby
agree, to the fullest extent permitted by Law, that the rate of exchange used
shall be that at which in accordance with normal banking procedures the Lender
could purchase the Original Currency with the Other Currency after any premium
and costs of exchange on the Business Day preceding that on which final judgment
is given.

         (ii) INDEMNITY IN CERTAIN EVENTS. The obligation of the Borrower in
respect of any sum due from the Borrower to the Lender hereunder shall,
notwithstanding any judgment in an Other Currency, whether pursuant to a
judgment or otherwise, be discharged only to the extent that, on the Business
Day following receipt by the Lender of any sum adjudged to be so due in such
Other Currency, the Lender may in accordance with normal banking procedures
purchase the Original Currency with such Other Currency. If the amount of the
Original Currency so purchased is less than the sum originally due to the Lender
in the Original Currency, the Borrower agrees, as a separate obligation and
notwithstanding any such judgment or payment, to indemnify the Lender against
such loss.

2.8  FEES.

2.8a REVOLVING CREDIT COMMITMENT FEE. The Borrower agrees to pay to the Lender
on March 31, 1999 and quarterly thereafter to and including the Revolving Credit
Termination Date, a Revolving Credit Commitment Fee calculated at the rate of
1/4 of 1% per annum on the average daily 




                                     - 22 -
<PAGE>   24


(computed at the opening of business) unused amount of the Revolving Credit
Commitment for the quarter then ending; provided, that the first payment shall
be calculated for the period beginning on the Closing Date and ending on March
31, 1999. All payments of the Revolving Credit Commitment Fee shall be deemed
fully earned when paid and shall be nonrefundable.

2.8b FACILITY FEE. The Borrower shall pay to the Lender prior to or
simultaneously with the first advance hereunder the Facility Fee in the amount
of $20,000, which shall be fully earned when paid and non-refundable.

2.8c LATE FEES. The Lender shall have the right to assess a late fee if any
principal, interest, fees or other amounts due under the Loan Documents are not
paid within ten (10) days of their due date. Such late fee shall be in an amount
equal to the greater of $20.00 or one percent (1%) of the amount not timely
paid. 2.9 LOAN ACCOUNT. The Lender shall open and maintain on its books records
relating to the Loans made, repayments, prepayments, the computation and payment
of interest and the Fees and the computation of other amounts due and sums paid
to the Lender pursuant hereto. Except in the case of manifest error in
computation, such records shall be presumed to be conclusive and binding on the
Borrower as to the amount at any time due to the Lender from the Borrower
pursuant hereto.

2.10 TIME, PLACE AND MANNER OF PAYMENTS. All payments to be made by the Borrower
under any of the Loan Documents shall be made at the principal office of the
Lender at 20 Stanwix Street, Pittsburgh Pennsylvania and shall be paid in
Dollars in immediately available funds no later than 12:00 noon (Eastern time)
on the date such payment is due. If the date on which any payment is due is not
a Business Day such payment shall be due and payable on the next succeeding day
which is a Business Day and interest shall accrue on any principal amount of
such a payment until the date on which such principal amount is paid.

2.11 PAYMENT FROM ACCOUNTS MAINTAINED BY THE BORROWER. In the event that any
payment of principal, interest, Fees or any other amount due the Lender under
any of the Loan Documents is not paid when due, the Lender is hereby authorized
to effect such payment by debiting any demand deposit account of the Borrower
maintained with the Lender. This right of debiting accounts of the Borrower is
in addition to any right of set-off accorded the Lender hereunder or by
operation of law.

2.12 ALL OBLIGATIONS TO CONSTITUTE ONE OBLIGATION. All Obligations shall
constitute one general obligation of the Borrower, and shall be secured by the
Lender's security interest in and lien upon all of the Collateral of the
Borrower and by all other security interests and liens heretofore, now or at any
time or times hereafter granted by the Borrower to the Lender.

3.4 VALIDITY; BINDING EFFECT AND ENFORCEABILITY. The Loan Documents to which the
Borrower is a party constitute legal, valid and binding obligations of the

<PAGE>   26


of its businesses, operations or properties, at law or in equity, the results of
which, if adversely determined, could reasonably be expected to have a Material
Adverse Effect or which purport to restrain or enjoin (temporarily,
preliminarily or permanently) the performance by the Borrower of any action
contemplated by any Loan Document. All pending and, to the Borrower's knowledge,
threatened, actions, suits, proceedings and investigations affecting the
Borrower are described on Schedule 3.9.

8.2 AMENDMENTS AND WAIVERS. The Lender and the Borrower may, subject to the
provisions of this Section 8.2, from time to time enter into amendments,
extensions, supplements and replacements to any of the Loan Documents, and the
Lender in its discretion may from time to time waive compliance with a provision
of any of the Loan Documents or consent to actions taken or desired to be taken
by the Borrower. All such amendments, extensions, supplements, replacements,
waivers and consents must be in writing and signed by the Lender and the
Borrower in order to be effective. Each waiver and consent shall be effective
only for the specific instance and for the specific purpose for which it is
given. In the case of any waiver, the Borrower and the Lender shall be restored
to their former positions and rights, and any Event of Default waived shall be
deemed to be cured and not continuing, but no such waiver shall extend to any
subsequent or other Event of Default, or impair any right consequent thereon.
Neither the acceptance by the Lender of any payment required under the Loan
Documents after its due date, nor the acceptance by the Lender of interest at
the Default Rate or any other increased rate, shall constitute any waiver of the
Lender's rights under the Loan Documents.

8.3 TAXES. The Borrower agrees to pay any and all stamp, document, transfer or
recording taxes, filing fees and similar impositions payable or hereafter
determined to be payable in connection with the Loan Documents and any other

future claims or liabilities with respect to, or resulting from any delay in
paying or omission to pay, any such taxes or similar impositions.

         (i) All (A) costs and expenses incurred by or on behalf of the Lender
in connection with the preparation, negotiation, execution and delivery of the
Loan Documents and any and all other documents and instruments prepared in
connection herewith and therewith, including the Lender's reasonable legal fees
(but not out-of-pocket costs, which shall be paid by the Lender) in connection
therewith (which shall not exceed $7,500), and (B) reasonable costs and expenses
of the Lender (including but not limited to reasonable fees and expenses of the
Lender's in-house and outside counsel) in connection with all amendments,
waivers, consents, renewals, and other documents and instruments prepared or
entered into from time to time in connection with the Loan Documents; and

         (ii) All costs and expenses of the Lender (including without limitation
the fees and expenses of the Lender's counsel) in connection with (A) the
enforcement of the Loan Documents arising pursuant to a breach by any Loan Party
of any of the terms, conditions, representations, warranties or covenants of any
Loan Document to which it is a party, (B) the sale of or other action taken with
respect to the Collateral, (C) defending or prosecuting any actions, suits or
proceedings relating to any of the Loan Documents, and (D) any bankruptcy,

         (iii) All of such costs and expenses shall be payable by the Borrower
to the Lender as agreed upon by the Lender and the Borrower, or if not agreed
upon, upon demand by the Lender, shall constitute Obligations under this
Agreement and shall bear interest at a rate per annum equal to the Default Rate
if not paid when due. The Borrower's obligations to pay such costs and expenses
shall survive the Termination Date.

the Lender.

8.8 ASSIGNMENTS AND PARTICIPATIONS. The Lender may, in the ordinary course of
its commercial banking business and in accordance with applicable law, at any
time assign to any Person or sell to one or more participants (which Person or
participants may be Affiliates of the Lender) portions of or participations in
any interest of the Lender hereunder or under the other Loan Documents. In the
event of any sale of a participation, the Lender's obligations under this
Agreement to the Borrower shall remain unchanged, the Lender shall remain solely
responsible for its performance under this Agreement, the Lender shall remain
the holder of the Revolving Credit Note for all purposes under this Agreement,

<PAGE>   40


rights and obligations under the Loan Documents. The Borrower agrees that if
amounts outstanding under the Loan Documents are due and unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each participant shall be deemed to have, to the extent
permitted by applicable law, the right of setoff in respect of its participation

conditions, and other provisions applicable thereto.

8.10 SEVERABILITY. Any provision of this Agreement which is prohibited or

liability of the Borrower for payment of interest, including late charges,
pursuant hereto, shall not exceed the maximum amount of interest permitted by
law to be charged, collected or received from the Borrower. If the Lender

apply such excess to the reduction of the unpaid principal amount due hereunder,
or if no principal is then due, such excess shall be refunded to the Borrower.

8.13 GOVERNING LAW. UNLESS OTHERWISE SPECIFICALLY STATED, THE LOAN DOCUMENTS
SHALL BE CONTRACTS MADE UNDER AND GOVERNED BY THE LAWS OF THE COMMONWEALTH OF

PERSONAL JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY,
PENNSYLVANIA AND THE DISTRICT COURT OF THE UNITED STATES FOR THE WESTERN
DISTRICT OF PENNSYLVANIA AND WAIVES AND HEREBY ACKNOWLEDGES THAT THE BORROWER IS

necessary to produce or account for more than one such counterpart signed by the
other party against whom enforcement is sought.

8.18 WAIVER OF JURY TRIAL. THE BORROWER AND THE LENDER EACH HEREBY WAIVE THE
RIGHT TO A TRIAL BY JURY IN ANY COURT AND IN ANY ACTION OR PROCEEDING OF ANY
TYPE IN WHICH THE BORROWER, THE LENDER, OR ANY OF THEIR RESPECTIVE SUCCESSORS OR
ASSIGNS IS A PARTY, AS TO ALL MATTERS AND THINGS ARISING DIRECTLY OR INDIRECTLY
