                   FOR THE FISCAL YEAR ENDED DECEMBER 31, 1998


                                     PART I

ITEM 1. BUSINESS

GENERAL

        Airlease Ltd., A California Limited Partnership (the "Partnership" or
"Airlease"), was formed in 1986. The General Partner of the Partnership (the
"General Partner") is Airlease Management Services, Inc., a Delaware
corporation. Until October 31, 1996 the General Partner was a wholly owned
subsidiary of USL Capital Corporation ("USL Capital"), which in turn was an
indirect subsidiary of Ford Motor Company. On October 31, 1996, BA Leasing &
Capital Corporation, a California corporation ("BALCAP") purchased the stock of
the General Partner from USL Capital and now the General Partner is a wholly
owned subsidiary of BALCAP and USL Capital no longer has any affiliation with
the Partnership. BALCAP is a wholly owned indirect subsidiary of BankAmerica
Corporation. A total of 4,625,000 Depository Units representing limited
Partnership interests ("Units") in the partnership are outstanding, of which
3,600,000 are held by the public and 1,025,000 are owned by BALCAP and its
subsidiaries.

        The Partnership invests in commercial aircraft and leases the aircraft
to others, primarily airlines, pursuant to finance (full payout) or operating
leases.

PRINCIPAL INVESTMENT OBJECTIVES

        The business of the Partnership is to acquire and own, either directly
or through joint ventures, aircraft and to lease such aircraft primarily to
airlines. The Partnership's principal investment objectives are to generate
income for quarterly cash distributions to Unitholders and to own a portfolio of
leased aircraft. The Partnership's original intent was that until January 1,
2005, it would use a substantial portion of the cash derived from the sale,
refinancing or other disposition of aircraft to purchase additional aircraft if
attractive investment opportunities were available.



                                       3
<PAGE>   4

        As previously reported, as part of a plan to mitigate the adverse
financial effects of changes in tax law, in 1997 unitholders authorized the
General Partner to decide not to make new aircraft investments, to sell aircraft
when attractive opportunities arise, to distribute the proceeds and to liquidate
the Partnership when all assets are sold. The General Partner will consider
whether it is in the best interest of unitholders to cease making new aircraft
investments as opportunities arise, in light of market conditions and the
Partnership's competitive position. Based on its investment experience and its
knowledge of the market, the General Partner believes that attractive investment
opportunities like those made by the Partnership in the past probably will not
be available. In the event that aircraft are sold and appropriate alternative
investments are not available, the Partnership would distribute sale proceeds to
unitholders (after repaying debt and establishing appropriate reserves), and
this would result in a further reduction of the Partnership's portfolio.

AIRCRAFT PORTFOLIO

        The Partnership's aircraft portfolio consists of narrow-body
(single-aisle) twin and tri-jet commercial aircraft which were acquired as used
aircraft. Although the Partnership is permitted to do so, the Partnership does
not own interests in aircraft which were acquired as new aircraft; nor does the
Partnership own any wide-body aircraft, such as the Boeing 747 and MD-11, or any
turboprop or prop-fan powered aircraft.

        laws and regulations governing aircraft noise.

(2)     The investment tax credits and the accelerated depreciation originally
        available upon delivery of the aircraft on lease to USAirways, Inc.
        (formerly USAir, Inc.) ("USAirways") were sold in 1981 pursuant to a tax
        benefit transfer lease, which terminated November, 1991. See Note 9 of
        Notes to Financial Statements.

(3)     The purchase price includes $6.9 million of conversion costs for the
        upgrade of the aircraft from a Stage II passenger to a Stage III
        freighter aircraft.

(4)     The Partnership originally acquired a 50% interest in this aircraft in
        1988 for a purchase price of $10.1 million. On January 31, 1997 the
        Partnership purchased the remaining 50% interest from USL Capital for a
        purchase price of $5.7 million.


        At December 31, 1998, the book value of aircraft by lessee as a percent
of total assets was as follows: US Airways, 71.9%; FedEx, 12.8%; and TWA, 14.8%.
Revenues by lessee as a percentage of total revenue for 1998 and 1997,
respectively, were as follows: US Airways, 77.4% and 73.5%; TWA, 17.0% and
15.2%; FedEx, 5.6% and 5.3%.

        See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS" for a further discussion of the Partnership's lessees.

<PAGE>   6
        The Partnership's lessees have the following fair market value renewal
options: US Airways has the right to renew its lease as to any of the aircraft
for up to three additional renewal terms of one year each at a fair market value
rental, provided that the number of aircraft to be returned at the end of any
renewal term may not be less than two; FedEx has the right to renew its lease
for one six-month term at the current rent payable under the lease, and
thereafter for four successive one year terms at a fair market value rental; and
TWA has the right to renew its lease for one term of one, two, three or four
years at fair market value rentals.

COMPETITIVE POSITION OF THE PARTNERSHIP

        The aircraft leasing industry has become increasingly competitive. In
making aircraft investments, leasing aircraft to lessees, and seeking purchasers
of aircraft, the Partnership competes with large leasing companies, aircraft
manufacturers, airlines and other operators, equipment managers, financial
institutions and other parties engaged in leasing, managing, marketing or
remarketing aircraft. Affiliates of the General Partner are engaged in many of
these businesses and may be deemed to be in competition with the Partnership.
There are many large leasing companies which have the financial strength to
borrow at very low rates and to obtain significant discounts when purchasing
large quantities of aircraft. The lower capital and acquisition costs enjoyed by
these large leasing companies permit them to offer airlines lower lease rates
than smaller leasing companies can offer. The Partnership does not have the
resources to purchase newer aircraft or to purchase aircraft at volume discounts
and has only a limited ability to use tax deferrals in its pricing.

        As previously reported to Unitholders, the Partnership's access to
capital is limited. Since all Cash Available from Operations, as defined in the
Limited Partnership Agreement, is distributed, there is no build up of equity
capital, and acquisitions must be funded from proceeds available when aircraft
are sold or from debt. Access to debt is limited because most of the
Partnership's aircraft are being used to collateralize existing borrowings. In
general, the Partnership's pricing is uncompetitive for new acquisitions because
of its limited sources and high cost of capital.

        Because of these factors, finding new aircraft investments like those
made by the Partnership in the past and that offer an appropriate balance of
risk and reward has been difficult. During the past six years the Partnership
has made only two aircraft investments, both of which were possible because of
special circumstances.

        In 1996 and 1997, the Partnership sold interests in eight aircraft (a
50% interest in an aircraft on lease to Finnair, a one-third interest in six
aircraft on lease to Continental, and a 50% interest in one aircraft leased to
Sun Jet International, Inc.) at a profit. See "Disposition of Aircraft" below.
However because of the factors described above, the Partnership was unable to
reinvest the proceeds in aircraft at an acceptable return, and the General
Partner determined that the best use of the net proceeds was to distribute them
to Unitholders. These sales and distributions have reduced the size of the
Partnership's portfolio.



                                       6
<PAGE>   7
EXISTING PARTICIPANTS IN LEASES

        USL Capital originally participated equally with the Partnership in all
aircraft now owned by the Partnership except the aircraft on lease to US Airways
(the "US Airways Aircraft"). In April 1993 the Partnership leased two aircraft
(held jointly with USL Capital), which were previously off lease, to FedEx. In
September 1993 the Partnership exchanged its 50% interest in the two aircraft
for a 100% interest in one aircraft and pledged the aircraft and the lease as
collateral to obtain funds to upgrade the aircraft from a Stage II passenger
aircraft to a Stage III freighter. In January 1997, the Partnership purchased a
50% interest in the TWA Aircraft formerly owned by USL Capital, and now owns a
100% interest in this aircraft.


DESCRIPTION OF LEASES

        All aircraft now owned by the Partnership are leased to third parties
pursuant to full-payout leases (direct finance). The Sun Jet Aircraft was
jointly owned by BALCAP (which purchased USL Capital's interest in this aircraft
in 1996) and the Partnership until it was sold on September 29, 1997. Generally,
operating leases are for a shorter term than full-payout leases and, therefore,
it is necessary to remarket the aircraft in order to recover the full
investment. Full-payout leases are generally for a longer term and hence provide
more predictable revenue than do operating leases.

        All of the Partnership's leases are net leases, which provide that the
lessee will bear the direct operating costs and the risk of physical loss of the
aircraft; pay sales, use or other similar taxes relating to the lease or use of
the aircraft; maintain the aircraft; indemnify the Partnership-lessor against
any liability suffered by the Partnership as the result of any act or omission
of the lessee or its agents; maintain casualty insurance in an amount equal to
the specific amount set forth in the lease (which may be less than the market
value of the aircraft); and maintain liability insurance naming the Partnership
as an additional insured with a minimum coverage which the General Partner deems
appropriate. In general, substantially all obligations connected with the
ownership and operation of the leased aircraft are assumed by the lessee and
minimal obligations are imposed upon the Partnership. Default by a lessee may
cause the Partnership to incur unanticipated expenses. See "Government
Regulation" below.

        Certain provisions of the Partnership's leases may not be enforceable
upon a default by a lessee or in the event of a lessee's bankruptcy. The
enforceability of leases will be subject to limitations imposed by Federal,
California, or other applicable state law and equitable principles.

        In order to encourage equipment financing to certain transportation
industries, Federal bankruptcy laws traditionally have afforded special
treatment to certain lenders or lessors who have provided such financing.
Section 1110 ("Section 1110") of the United States Bankruptcy Code, as amended
(the "Bankruptcy Code"), implements this policy by creating a category of
aircraft lenders and lessors whose rights to repossession are substantially
improved. If a



                                       7
<PAGE>   8
transaction complies with Section 1110, the transaction is not affected by the
automatic stay provisions of the Bankruptcy Code (and thus, the lender or lessor
may repossess the equipment), unless within 60 days after commencement of a
bankruptcy proceeding the trustee agrees to perform all obligations of the
debtor under the agreement or lease and all defaults (except those relating to
insolvency or insolvency proceedings) are cured within such 60-day period. One
court has recently held that section 1110 does not apply after the 60-day
period, and thus the automatic stay may apply after such 60-day period.

        On October 22, 1994, the President signed the Bankruptcy Reform Act of
1994 (the "Reform Act"). The Reform Act made several changes to Section 1110,
such that it now protects all transactions involving qualifying equipment,
whether the transaction is a lease, conditional sale, purchase money financing
or customary refinancing. For equipment first placed in service on or prior to
the date of enactment, the requirement that the lender provide purchase money
financing continues to apply, but there is a "safe harbor" definition for
leases, so that Section 1110 benefits will be available to the lessor without
regard to whether or not the lease is ultimately determined to be a "true"
lease. This safe harbor is not the exclusive test so that other leases which do
not qualify under the safe harbor, but which are true leases, will continue to
be covered as leases by Section 1110. The Partnership may not be entitled to the
benefits of Section 1110 upon insolvency of a lessee airline under all of its
leases.

        In the past, the Partnership had interests in aircraft leased to
operators based outside the United States. It is possible that the Partnership's
aircraft could be leased or subleased to foreign airlines. Aircraft on lease to
such foreign operators are not registered in the United States and it is not
possible to file liens on such foreign aircraft with the Federal Aviation
Administration (the "FAA"). Further, in the event of a lessee default or
bankruptcy, repossession and claims would be subject to laws other than those of
the United States.

AIRCRAFT REMARKETING

        On termination of a lease and return of the aircraft to the Partnership,
the Partnership must remarket the aircraft to realize its full investment. Under
the Amended and Restated Agreement of Limited Partnership, as amended ("Limited
Partnership Agreement"), the remarketing of aircraft may be through a lease or
sale. The terms and conditions of any such lease would be determined at the time
of the re-lease, and it is possible (although not anticipated at this time) that
the lease may not be a net lease. The General Partner will evaluate the risks
associated with leases which are not net leases prior to entering into any such
lease. The General Partner has not established any standards for lessees to
which it will lease aircraft and, as a result, there is no investment
restriction prohibiting the Partnership from doing business with any lessee,
including "start-up" airlines. However, the General Partner will analyze the
credit of a potential lessee and evaluate the aircraft's potential value prior
to entering into any lease.

DISPOSITION OF AIRCRAFT

        The Partnership's original intent was to dispose of all its aircraft by
the year 2011, subject to prevailing market conditions and other factors.
However, in 1997 unitholders authorized the General Partner not to make new
investments, to sell aircraft when attractive opportunities arise, to distribute
the proceeds and to liquidate the Partnership when all assets are sold. See
"Principal Investment Objectives."

        Under the Limited Partnership Agreement, aircraft may be sold at any
time whether or not the aircraft are subject to leases if, in the judgment of
the General Partner, it is in the best interest of the Partnership to do so.

        In March 1996, the Partnership sold its 50% interest in one MD-82 on
lease to Finnair to a third party for approximately $6.9 million, resulting in a
net gain of approximately $556,000. The Partnership had acquired its interest in
this aircraft in April 1992, for approximately $8.5 million. A portion of the
sale proceeds were used to pay off the outstanding balance under a non-recourse
loan which was collateralized by this aircraft and the balance, after retaining
a reserve for liquidity purposes, was distributed to Unitholders. See
"Competitive Position of the Partnership" above.

        The Partnership sold its one-third interest in six 737-200 aircraft on
lease to Continental at lease expiration on December 31, 1996, at a sale price
of approximately $3.1 million, resulting in a net gain of approximately $1.9
million. The proceeds were distributed to Unitholders in the first quarter of
1997. See "Competitive Position of the Partnership" above.

        On September 29, 1997 the Partnership sold its one-half ownership
interest in a DC9-51 aircraft on lease to Sun Jet International, Inc. The sale
price was $1.2 million, resulting in a gain of $393,000 even though the lessee
had filed for bankruptcy in June 1997, and had ceased making the rent payments.
The proceeds were distributed to Unitholders in the fourth quarter of 1997. See
"Competitive Position of the Partnership" above.

        The Partnership is permitted to sell aircraft to affiliates of the
General Partner at the fair market value of the aircraft at the time of sale as
established by an independent appraisal. The General Partner will receive a
Disposition or Remarketing Fee for any such sale.

JOINT VENTURES/GENERAL ARRANGEMENTS

        Under the Limited Partnership Agreement, the Partnership may enter into
joint ventures with third parties to acquire or own aircraft. No such joint
ventures presently exist. Generally, each party to a joint venture is jointly
responsible for all debts and obligations incurred by the joint venture, and the
joint venture will be treated as a single entity by third parties. The
Partnership may become liable to third parties for obligations of the joint
venture in excess of those contemplated by the terms of the joint venture
agreement. There can be no assurance that



                                       9
<PAGE>   10
the Partnership will be able to obtain control in any joint ventures, or that,
even with such control the Partnership will not be adversely affected by the
decisions and actions of the co-venturers. The General Partner attempts to
ensure that all such agreements will be fair and reasonable to the Partnership,
although joint ventures with affiliates of the General Partner may involve
potential conflicts of interest.

BORROWING POLICIES

        Under the Limited Partnership Agreement, the Partnership may borrow
funds or assume financing in an aggregate amount equal to less than 50% of the
higher of the cost or fair market value at the time of the borrowing of all
aircraft owned by the Partnership. The Partnership may exceed such 50% limit for
short-term borrowing so long as the General Partner uses its best efforts to
comply with such 50% limit within 120 days from the date such indebtedness is
incurred or if the borrowed funds are necessary to prevent foreclosure on any
Partnership asset. There is no limitation on the amount of such short-term
indebtedness. The General Partner is authorized to borrow for working capital
purposes and to make distributions. See "MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS--Liquidity and Capital Resources"

MANAGEMENT OF AIRCRAFT PORTFOLIO

        Aircraft management services are provided by the General Partner and its
affiliates. The fees and expenses for these services are reviewed annually and
are subject to approval by the Audit Committee of the Partnership. See Note 7 of
Notes to Financial Statements.

REGISTRATION OF AIRCRAFT; UNITED STATES PERSON

        Under the Federal Aviation Act, as amended (the "FAA Act"), the
operation of an aircraft not registered with the Federal Aviation Administration
(the "FAA") in the United States is generally unlawful. Subject to certain
limited exceptions, an aircraft may not be registered under the FAA Act unless
it is owned by a "citizen of the United States" or a "resident alien" of the
United States. In order to attempt to ensure compliance with the citizenship
requirements of the FAA Act, the Limited Partnership Agreement requires that all
Unitholders (and all transferees of Units) be United States citizens or resident
aliens within the meaning of the FAA Act.

GOVERNMENT REGULATION

        GENERAL

        The ownership and operation of aircraft in the United States are
strictly regulated by the FAA, which imposes certain minimum restrictions and
economic burdens upon the use, maintenance and ownership of aircraft. The FAA
Act and FAA regulations contain strict provisions governing various aspects of
aircraft ownership and operation, including aircraft inspection and
certification, maintenance, equipment requirements, general operating and flight
rules, noise levels, certification of personnel and record keeping in connection
with aircraft maintenance. FAA policy has given high priority to aviation
safety, and a primary objective of FAA regulations is that an aircraft be
maintained properly during its service life. FAA regulations establish standards
for repairs, periodic overhauls and alterations and require that the owner or
operator of an aircraft establish an airworthiness inspection program to be
carried out by certified mechanics qualified to perform aircraft repairs. Each
aircraft in operation is required to have a Standard Airworthiness Certificate
issued by the FAA.

        MAINTENANCE

        The Partnership, as the beneficial owner of aircraft, bears the ultimate
responsibility for compliance with certain federal regulations. However, under
all of the Partnership's aircraft leases, the lessee has the primary obligation
to ensure that at all times the use, operation, maintenance and repair of the
aircraft are in compliance with all applicable governmental rules and
regulations and that the Partnership/lessor is indemnified from loss by the
lessee for breach of any of these lessee responsibilities. Changes in government
regulations after the Partnership's acquisition of aircraft may increase the
cost to, and other burdens on, the Partnership of complying with such
regulations.

        The General Partner monitors the physical condition of the Partnership's
aircraft and periodically inspects them to attempt to ensure that the lessees
comply with their maintenance and repair obligations under their respective
leases. Maintenance is further regulated by the FAA which also monitors
compliance. At lease termination, the lessees are required to return the
aircraft in airworthy condition. The Partnership may incur unanticipated
maintenance expenses if a lessee were to default under a lease and the
Partnership were to take possession of the leased aircraft without such
maintenance having been completed. If the lessee defaulting is in bankruptcy,
the General Partner will file a proof of claim for the required maintenance
expenses in the lessee's bankruptcy proceedings and attempt to negotiate payment
and reimbursement of a portion of these expenses. The bankruptcy of a lessee
could adversely impact the Partnership's ability to recover maintenance expense.

        From time to time, aircraft manufacturers issue service bulletins and
the FAA issues airworthiness directives. These bulletins and directives provide
instructions to aircraft operators in the maintenance of aircraft and are
intended to prevent the occurrence of accidents arising 



                                       11
<PAGE>   12
from flaws discovered during maintenance or as the result of aircraft incidents.
Compliance with airworthiness directives is mandatory.

        A formal program to control corrosion in all aircraft is included in the
FAA mandatory requirements for maintenance for each type of aircraft. These FAA
rules and proposed rules evidence the current approach to aircraft maintenance
developed by the manufacturers and supported by the FAA in conjunction with an
aircraft industry group. The Partnership may be required to pay for these FAA
requirements if a lessee defaults or if necessary to re-lease or sell the
aircraft.

        In January 1999 the FAA issued an airworthiness directive setting
payload weight limitations on the Boeing 727 aircraft which were converted from
passenger to freight configuration. The directive requires extensive structural
modifications to strengthen the aircraft's floor, if the aircraft is to continue
to operate under the existing payload limits. If these modifications are not
performed, the directive sets substantially reduced payload limits. This
airworthiness directive applies to the aircraft on lease to FedEx. Under the
lease covering this aircraft, FedEx is required to take the steps necessary to
comply with airworthiness directives imposed during the lease term. However,
airworthiness directives may affect the residual value of the aircraft or
FedEx's decision to exercise fair market value renewal options under the lease.


        AIRCRAFT NOISE

        The FAA, through regulations, has categorized certain aircraft types as
Stage I, Stage II and Stage III according to the noise level as measured at
three designated points. Stage I aircraft create the highest measured noise
levels. Aircraft which exceed Stage I noise maximums are no longer allowed to
operate from civil airports in the United States.

        In general, the Aviation Safety and Capacity Act of 1990 bans the
operation of Stage II aircraft after December 31, 1999 for aircraft operated
within the continental United States. The Act also allows United States airports
to impose their own Stage II noise bans before the formal cut-off date, provided
that an analysis of the costs and benefits of the restriction is presented and
180 days are allowed for public comment. The Act affects about 2,500 Stage II
aircraft operated by United States airlines.


        See "Aircraft Portfolio" above, for a description of the Partnership's
aircraft portfolio. At December 31, 1998, all of the aircraft in the
Partnership's portfolio were Stage III aircraft

ACQUISITION OF ADDITIONAL AIRCRAFT

        In 1997 unitholders authorized the General Partner to decide not to make
new aircraft investments, to sell aircraft when attractive opportunities arise,
to distribute the proceeds and to liquidate the Partnership when all assets are
sold. See "Principal Investment Objectives" above.



                                       12
<PAGE>   13

        If the Partnership were to acquire additional aircraft, it could do so
in many different forms, such as in sale/leaseback transactions, by purchasing
interests in existing leases from other lessors, by making loans secured by
aircraft or by acquiring or financing leasehold interests in aircraft. The
Partnership is permitted to acquire aircraft from affiliates of the General
Partner subject to limitations set forth in the Limited Partnership Agreement.

        Prior to September 30, 1991, the General Partner and USL Capital were
required to offer the Partnership a 50% participation interest in certain
aircraft leasing investments made by Related Entities, as defined in the Limited
Partnership Agreement. After September 30, 1991 and while the General Partner
was an affiliate of USL Capital, the General Partner and USL Capital could, but
were not obligated to, offer investment opportunities to the Partnership. The
Partnership was required to accept suitable opportunities provided that the
General Partner and Related Entities made at least 20% (including their
investment through ownership of Units and the General Partner's interest) of the
total investment made by Related Entities and the Partnership in such
transactions. In the event that the Partnership elected not to make or to make
only a portion of an investment offered to it by an affiliate, the remaining
investment could be made by affiliates of the General Partner or third parties.

        The General Partner believes that since it is no longer affiliated with
USL Capital, the limitation as to making investments with Related Entities
should no longer apply and that the Partnership should be able to invest in any
aircraft leasing transactions deemed suitable by the General Partner. In
determining whether an investment is suitable for the Partnership, the General
Partner will consider the following factors: the expected cash flow from the
investment and whether existing Unitholders' investment will be diluted; the
existing portfolio of the Partnership and the effect of the investment on the
diversification of the Partnership's assets; the amount of funds available to
finance the investment; the ability of the Partnership to obtain additional
funds through debt financing, by issuing Units, or otherwise; the cost of such
additional funds and the time needed to obtain such funds; the amount of time
available to remove contingencies prior to making the investment; projected
Federal income tax effect of the investment; projected residual value, if any;
any legal or regulatory restrictions; and other factors deemed relevant by the
General Partner.

        The General Partner and its affiliates are not obligated to make any
investment opportunity available to the Partnership, and if any of them are
presented with a potential investment opportunity, it may be made by any of them
without being offered to the Partnership. In addition, in determining which
entity should invest in a particular transaction, it may be possible to
structure the transaction in various ways to make the acquisition more or less
suitable for the Partnership or for the General Partner or its affiliates.

FEDERAL INCOME TAXATION

The Partnership is considered a publicly traded Partnership ("PTP") under the
Revenue Act of 1987 with a special tax status, whereby it has not been subject
to federal income taxation. This 



                                       13
<PAGE>   14

special tax status was scheduled to expire at the beginning of 1998. However,
during 1997 federal and California tax laws were amended to provide that
publicly traded Partnerships may elect to continue to be publicly traded and
retain their Partnership tax status if they pay a federal tax of 3.5% and state
tax of 1% on their annual gross income beginning in January 1998. The
Partnership made an election to pay this tax beginning in 1998.

ITEM 2. PROPERTIES

        The Partnership does not own any real property, and shares office space
in the offices of BALCAP and its affiliates.

DISTRIBUTIONS TO UNITHOLDERS

        CASH DISTRIBUTIONS

        The Partnership makes quarterly cash distributions to Unitholders which
are based on Cash Available from Operations (as defined in the Limited
Partnership Agreement) and are partially tax sheltered. Form time to time the
Partnership also has made cash distributions from cash available from Sale or
Refinancing (as defined in the Limited Partnership Agreement.) Information on
the tax status of such payments, which is necessary in the preparation of
individual tax returns, is prepared and mailed to Unitholders as quickly as
practical after the close of each year. The size of the Partnership's portfolio
and future aircraft sales will affect distributions.

(1) Special cash distribution from sale proceeds.


        CASH AVAILABLE FROM OPERATIONS

        The Partnership distributes all Cash Available from Operations (as
defined in the Limited Partnership Agreement). The Partnership is authorized to
make distributions from any source, including reserves and borrowed funds.
Distributions of Cash Available from Operations are allocated 99% to Unitholders
and 1% to the General Partner. The Partnership makes distributions of Cash
Available from Operations generally on the fifteenth day of each February, May,
August and November to Unitholders of record on the last business day of the
calendar quarter preceding payment.

        CASH AVAILABLE FROM SALE OR REFINANCING

        The Partnership's original intent was that Cash Available From Sale or
Refinancing (as defined in the Limited Partnership Agreement) received prior to
January 1, 2005 would be retained for use in the Partnership's business,
provided that if the General Partner did not believe that attractive investment
opportunities exist for the Partnership, the Partnership could distribute Cash
Available from Sale or Refinancing. Any Cash Available from Sale or Refinancing
received after January 1, 2005 was not to be reinvested but was to be
distributed. However, in 1997, unitholders authorized the General Partner to
decide not to make new aircraft investments, to sell aircraft when attractive
opportunities arise, to distribute the proceeds and to liquidate the Partnership
when all assets are sold. See "BUSINESS-- Principal Investment Objectives." For
information as to the sales giving rise to distributions from Cash Available
from Sales or Refinancing, see "BUSINESS--Disposition of Aircraft."



                                       16
<PAGE>   17

        TAX ALLOCATIONS

        Allocations for tax purposes of income, gain, loss deduction, credit and
tax preference are made on a monthly basis to Unitholders who owned Units on the
first day of each month. Thus, for example, if an aircraft were sold at a gain,
that gain would be allocated to Unitholders who owned Units on the first day of
the month in which the sale occurred. If proceeds from this sale were
distributed to Unitholders, such proceeds would be distributed to Unitholders
who owned Units on the record date for such distribution, which, because of
notice requirements, likely would not occur in the same month as the sale. In
addition, a Unitholder who transfers his or her Units after the commencement of
a quarter but prior to the record date for that quarter will be allocated a
share of tax items for the first two months of that quarter without any
corresponding distribution of Cash Available from Operations for, among other
things, payment of any resulting tax.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS 

FORWARD-LOOKING STATEMENTS

The information set forth below and elsewhere in this Annual Report contains
certain forward-looking statements, which reflect the current view of the
partnership with respect to future events and financial performance. The words,
"expect", "intend", "believe", "anticipate", "likely" and "will" and similar
expressions generally identify forward-looking statements. These statements,
including the ones discussing the Year 2000 issue are subject to certain risks
and uncertainties, which could cause actual results, and events to differ
materially from those anticipated in the forward-looking statements.

Factors that could cause the partnership's actual results to differ from current
expectations include, among others, changes in the aircraft or aircraft leasing
market, economic downturn in the airline industry, default by lessees under
leases causing the partnership to incur uncontemplated expenses or not to
receive rental income as and when expected, changes in interest rates and
legislative or regulatory changes that adversely affect the value of aircraft.

LIQUIDITY AND CAPITAL RESOURCES

        The Partnership presently has three long-term debt facilities. At
December 31, 1998, the following amounts were outstanding: $5.1 million on a
7.4% non-recourse note collateralized by one aircraft leased to FedEx; $5.2
million on a 9.35% non-recourse note collateralized by one aircraft on lease to
Trans World Airlines; and $4.3 million on a long-term variable rate revolving
loan facility guaranteed by the Partnership and collateralized by two aircraft
on lease to USAirways. At December 31, 1998 and 1997, $14.5 million and $19.1
million, respectively, was outstanding under the Partnership's loan facilities.
At December 31, 1998 approximately $6.5 million remained available under the
revolving loan facility.

        In December 1998, the Partnership modified the fixed-rate loan
collateralized by the TWA aircraft. As a result of these modifications, the loan
was paid down by $2 million and the average life of the loan was reduced. In
addition, the interest rate on the remaining principal of $5.2 million was
reduced from 9.85% to 9.35%.

        In December 1998, the Partnership expanded its variable-rate revolving
loan facility by $5 million, $2 million of which was used to prepay the TWA debt
mentioned above. In addition, the interest rate on this loan facility was
reduced slightly.

        Long-term borrowings at December 31, 1998 represented 12% of the
original cost of the aircraft presently owned by the Partnership, including
capital expenditures for upgrades. The terms of the Partnership Agreement permit
debt to be at a level not exceeding 50% of such cost.

        Total scheduled debt service (principal and interest) on the fixed loans
in 1999 is $2.7 million, and the principal payment on the floating loan in 1999
is projected to be $2.1 million (if 



                                       19
<PAGE>   20
no purchase or sale of aircraft, or any unforeseen business events occur). Debt
service will be paid primarily from the rental payments received under aircraft
leases.

        Net cash provided by operating activities was $7.3 million for 1996,
$5.1 million for 1997, and $5.3 million for 1998. The decrease in net cash
provided by operating activities in 1997 and 1998 as compared with 1996 was due
to reduced rentals as a result of a smaller portfolio. In December 1996, the
Partnership sold its interest in six aircraft, reducing 1997 rentals by $1.3
million compared with 1996. The slight increase in 1998 reflects lower 1998
expenses as compared with 1997.

        Total debt service on the fixed loans as a percentage of net cash
provided by operating activities was 107%, 152%, and 166% for 1996, 1997 and
1998, respectively. However, cash flow from operating activities does not fully
reflect cash receipts from lease payments. When the excess of rental receipts
above finance lease income is added to cash flow from operating activities, the
ratios become 50%, 68%, and 71% respectively. The higher 1998 ratio as compared
with 1997 primarily reflects the $2 million early principal pay-down of a fixed
loan in 1998. The pay-down was mainly financed by the variable line of credit.
The higher 1997 ratio as compared with the 1996 ratio is the result of the
decrease in the net cash from operations due to a smaller portfolio, while the
debt service (principal and interest) remained at about the same level.

        Cash distributions paid by the Partnership were $12.6 million ($2.70 per
unit) in 1996, $12.4 million ($2.65 per unit) in 1997, and $7.8 million ($1.68
per unit) in 1998. Distributions paid in 1996 included a special cash
distribution of 80 cents per unit made from a portion of the sale proceeds
received from the sale of a 50% interest in one MD-82 aircraft. Distributions
paid in 1997 included two special cash distributions. The first, was a
distribution of 63 cents per unit made from the proceeds received from the
December 31, 1996 sale of the Partnership's interest in six 737-200 aircraft,
and the second was a distribution of 22 cents per unit made from the proceeds
received from the September 29, 1997 sale of the Partnership's 50% interest of
one DC9-51. There were no special cash distributions paid in 1998.

        Partnership net income was $8.7 million in 1996, $5.5 million in 1997,
and $4.9 million in 1998. The decline in net income from 1996 to 1997 largely
reflects fewer gains on sale, whereas the decline from 1997 to 1998 primarily
reflects the imposition of federal taxation at the Partnership level. Pursuant
to the Limited Partnership Agreement, the Partnership distributed all Cash
Available from Operations and also made special cash distributions, as described
above. Since such distributions were in excess of earnings, Partnership equity
declined from $61.1 million at December 31, 1997 to $58.3 million at December
31, 1998, and limited partner equity per unit declined from $13.08 to $12.48.
From a limited partner perspective, the portion of the distribution in excess of
net income constitutes a return of capital. Total cash distributions declared
since inception of the Partnership have exceeded total net income by $6.31 per
unit.

RESULTS OF OPERATIONS

1996



                                       20
<PAGE>   21

        In 1996, revenues were earned from fifteen aircraft, seven of which were
subject to finance leases (US Airways, TWA, and FedEx), and eight of were
subject to operating leases (Continental, Finnair, and Sun Jet). The aircraft
leased to Finnair was sold in March 1996. On December 31, 1996, the operating
lease with Continental covering six aircraft expired, and the aircraft were sold
on that date. At year-end 1996, all of the Partnership's lessees were current
under their lease agreements and none was in bankruptcy. The sales of the
Partnership's interests in aircraft on lease to Finnair and Continental produced
gains of $556,000 and $1.9 million, respectively.

1997 vs. 1996

        In 1997, revenues were earned from seven aircraft subject to finance
leases (US Airways, TWA, and FedEx). Finance lease income increased from 1996
due to the Partnership's purchase in January 1997 of an additional 50% interest
in the MD-82 aircraft on lease to TWA. In 1997 revenues were also earned from
one aircraft subject to an operating lease (Sun Jet). Sun Jet filed for
bankruptcy in June 1997, and the 22-year old aircraft was sold in September
1997, at a gain of $393,000. As of December 31, 1997, the Partnership no longer
owned interests in any aircraft subject to operating leases. At year-end 1997,
all of the Partnership's lessees were current under their lease agreements and
none was in bankruptcy.

1998 vs. 1997

        In 1998, all revenues were earned from aircraft subject to finance
leases. The revenue reduction in 1998 as compared with 1997 is primarily due to
the scheduled decline in finance lease income as the asset base declined. In
addition in 1997, the Partnership earned revenue from an aircraft on an
operating lease and from a gain on sale of such aircraft. No such revenues were
earned in 1998. At year-end 1998, all the Partnership's lessees were current
under their lease agreements and none was in bankruptcy.

        US Airways, the Partnership's major lessee (72% of total year-end
assets) reported profits of $538 million on revenues of $8.7 billion for 1998,
compared with profits of $1.0 billion on revenues of $8.5 billion for 1997.

        FedEx (13% of total year-end assets) reported profits of $421 million on
revenues of $13.3 billion for 1998 (fiscal year ended May 31, 1998), compared
with profits of $361 million on revenues of $11.5 billion for 1997.

        TWA (15% of total year-end assets), reported a net loss of $120 million
on revenues of $3.3 billion for 1998, compared with a net loss of $127 million
on revenues of $3.3 billion for 1997.

        For information regarding the percentage of total Partnership assets and
revenues represented by aircraft owned and leased by the Partnership, see
BUSINESS -- "Aircraft Portfolio."

        The Partnership believes that its revenues and income have not been
materially affected 



                                       21
<PAGE>   22

by inflation and changing prices because its principal items of revenue (rental
payments) and a majority of its expenses (interest) are at fixed long-term
rates.

        Expenses before taxes in 1998 were $2.8 million or $1.3 million lower
than the 1997 expenses of $4.1 million. In 1997, the Partnership incurred
investor reporting expenses in connection with the solicitation of unitholder
consents and depreciation expense related to the aircraft that was sold in
September 1997. Expenses in 1997 also included a provision for doubtful
accounts. No similar expenses were incurred in 1998. In January 1998 the
Partnership made an election to pay an annual tax at the Partnership level of
4.5% on its gross income beginning in 1998 in order to remain publicly traded.
As such, in 1998 the Partnership recorded a tax provision of $699,000, pursuant
to the newly imposed federal and state gross income tax.

YEAR 2000 ISSUE

        The year 2000 issue results from older computer programs using two,
rather than four digits to define a year, thus the programs do not recognize a
year that begins with "20" rather than the familiar "19." If not corrected, many
computer applications could fail or create erroneous results.

        Since the Partnership's operations consist primarily of collecting
periodic lease payments on a limited number of leases and making periodic debt
payments and distributions to its partners, the General Partner believes that
the Partnership's exposure to the Year 2000 problem is limited to the software
programs and services it obtains from suppliers and vendors. The Partnership's
leases and loans are supported by amortization schedules generated at the
inception of these transactions, generally making the tracking of payments and
recording of income and interest expense a manual process and thus independent
of computer software.

        The Partnership relies on third parties ("external relationships") such
as banks, financial intermediaries, and tax services to facilitate certain
business transactions. The Partnership has reviewed the impact of these external
relationships on its business and concluded that the two most critical service
providers are: the provider of the tax service that generates the K1 tax
statements to be used by our limited partners to complete their tax returns and
the stock transfer agent that facilitates the public trading of the
Partnership's units. In 1998, the Partnership contacted both vendors and has
been advised their systems either are Year 2000 compliant or will be compliant
prior to December 31, 1999.

        The Partnership believes that due to its minimal reliance on computer
software to conduct its internal day to day transactions processing, the Year
2000 projected costs are negligible. However, the Partnership is also dependent
on third parties to fully conduct its business transactions as described above.
If these or other third parties fail to adequately resolve their Year 2000
issues, the Partnership could experience significantly increased administrative
costs or delays in unit transfer or tax preparation functions. The Partnership
anticipates that such costs would be incurred in locating alternative third
party vendors (which the Partnership believes exist) and transferring data to
such alternative vendors. The amount of such costs or potential 



                                       22
<PAGE>   23

delays is difficult to quantify.

        The Partnership will continue to monitor the progress of its third party
vendors, relative to the Year 2000 compliance, to attempt to ensure minimal
disruptions to its operations.

        The year 2000 compliance of each of the Partnership's lessees is
available from reports filed by the lessees with the Securities and Exchange
Commission.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

        The Partnership's assets consist of aircraft subject to leases accounted
for as financing leases, and thus consist of a future stream of fixed rental
payments and a residual interest in the aircraft. See Note 2 to Financial
Statements for information as to finance lease receivables. At December 31,
1998, the Partnership had long-term fixed-rate notes payable of $10,248,000 and
a revolving variable rate loan facility with $4,257,000 outstanding and
approximately $6,500,000 of credit available. See Note 4 to Financial Statements
for information as to minimum future principal payments due and the interest
rates applicable to the notes and revolving credit facility. Since the rental
payments under its leases are fixed, but a portion of its liabilities are based
on a variable interest rate, the assets and liabilities of the Partnership are
not perfectly hedged and the Partnership bears some risk of interest rate
fluctuations. Since a portion of its debt under the revolving credit facility is
for variable working capital needs, the General Partner believes that the risk
of interest fluctuations is appropriate under the circumstances.

        The financial statements and Notes to Financial Statements described in
Item 14(a) are set forth in Appendix A and are filed as part of this report.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

        On June 29, 1998, the Partnership engaged Ernst & Young L.L.P. as
independent auditors of the Partnership for the year ending December 31, 1998,
and dismissed Coopers & Lybrand L.L.P. (PriceWaterhouseCoopers L.L.P. after June
30, 1998.) This action was taken on the unanimous approval by the board of
directors of Airlease Management Services, Inc., the General Partner of the
Partnership, which acted on the recommendation of the audit committee of the
board of directors. The change was made primarily to achieve efficiencies in the
audit process and to reduce costs.

ITEM 11. EXECUTIVE COMPENSATION

         The Partnership does not pay or employ directly any directors or
officers. Each of the officers of the General Partner is also an officer or
employee of BALCAP and is not separately compensated by the General Partner or
the Partnership for services on behalf of the Partnership. Thus, there were no
deliberations of the General Partner's Board of Directors with respect to
compensation of any officer or employee.

         The Partnership reimburses the General Partner for fees paid to
Directors of the General Partner who are not otherwise affiliated with the
General Partner or its affiliates. In 1998, such unaffiliated directors were
paid an annual fee of $14,500 plus $500 for each meeting attended.

         The Partnership has not established any plans pursuant to which cash or
non-cash compensation has been paid or distributed during the last fiscal year
or is proposed to be paid or distributed in the future. The Partnership has not
issued or established any options or rights relating to the acquisition of its
securities or any plans therefor.

MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

Airlease Management Services, Inc. ("AMSI"), the General Partner of the
Partnership was a wholly owned subsidiary of USL Capital Corporation until
October 31, 1996, when BA Leasing and Capital Corporation ("BALCAP") purchased
100% of the stock of AMSI, AMSI is responsible for the preparation of the
Partnership's financial statements and the other financial information in this
report. This responsibility includes maintaining the integrity and objectivity
of the financial records and the presentation of the Partnership's financial
statements in accordance with generally accepted accounting principles.

The General Partner maintains an internal control structure designed to provide,
among other things, reasonable assurance that Partnership records include the
transactions of its operations in all material respects and to provide
protection against significant misuse or loss of Partnership assets. The
internal control structure is supported by careful selection and training of
financial management personnel, by written procedures that communicate the
details of the control structure to the Partnership's activities, and by
BALCAP's staff of operating control specialists who conduct reviews of adherence
to the Partnership's procedures and policies.

The Partnership's financial statements have been audited by Ernst & Young
L.L.P., independent auditors for the year ended December 31, 1998, and by
Coopers & Lybrand L.L.P., independent auditors for the years ended December 31,
1997 and 1996. Their audits were conducted in accordance with generally accepted
auditing standards which included consideration of the General Partner's
internal control structure. The Independent Auditor's Report appears on page A2.

The board of directors of the General Partner, acting through its Audit
Committee composed solely of directors who are not employees of the General
Partner, is responsible for overseeing the General Partner's fulfillment of its
responsibilities in the preparation of the Partnership's financial statements
and the financial control of its operations. The independent auditors have full
and free access to the Audit Committee and meet with it to discuss their audit
work, the Partnership's internal controls, and financial reporting matters.

INDEPENDENT AUDITORS' REPORT

To the Partners of Airlease Ltd.,
A California Limited Partnership:

We have audited the accompanying balance sheet of Airlease Ltd. as of December
31, 1998 and the related statements of income, changes in Partners'equity, and
cash flows for the year then ended. These financial statements are the
responsibility of the Partnership's management. Our responsibility is to express
an opinion on these financial statements based on our audit. The financial
statements of Airlease Ltd. for the years ended December 31, 1997 and 1996, were
audited by other auditors whose report dated January 21, 1998, expressed an
unqualified opinion on those statements.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Airlease Ltd. at December 31,
1998, and the results of its operations and its cash flows for the year then
ended in conformity with generally accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION - Airlease Ltd., A California Limited Partnership (the
"Partnership") engages in the business of acquiring, either directly or through
joint ventures, commercial jet aircraft, spare or separate engines and related
rotable parts ("aircraft") and leasing such aircraft to domestic and foreign
airlines and freight carriers. The General Partner is Airlease Management
Services, Inc., a wholly owned subsidiary of BA Leasing and Capital Corporation
("BALCAP"). BALCAP also holds 793,750 limited Partnership units and United
States Airlease Holding, Inc. ("Holding"), a wholly owned subsidiary of BALCAP,
holds 231,250 limited Partnership units. An additional 3,600,000 units are
publicly held.

BASIS OF PRESENTATION - The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.



                                      A-7

<PAGE>   40

FINANCE LEASES - Lease agreements, under which the Partnership recovers
substantially all its investment from the minimum lease payments are accounted
for as finance leases. At lease commencement, the Partnership records the lease
receivable, estimated residual value of the leased aircraft, and unearned lease
income. The original unearned income is equal to the receivable plus the
residual value less the cost of the aircraft (including the acquisition fee paid
to an affiliate of the General Partner). The remaining unearned income is
recognized as revenue over the lease term so as to approximate a level rate of
return on the investment.

OPERATING LEASES - Leases that do not meet the criteria for finance leases are
accounted for as operating leases. The Partnership's undivided interests in
aircraft subject to operating leases are recorded at cost which includes
acquisition fees paid to an affiliate of the General Partner. Aircraft are
depreciated over the related lease terms, generally five to nine years on a
straight-line basis to an estimated residual value, or over their useful lives
for aircraft held for lease or sale, on a straight-line basis to an estimated
salvage value.

DERIVATIVES - The Partnership accounts for derivative financial instruments on
an accrual basis when the cash flows generated from the hedging instruments
fulfill the objectives of the hedge strategy and when there is a high
correlation between the derivative and the hedged asset or liability. Under
accrual accounting interest differentials paid or received under interest rate
swap agreements are recognized as an adjustment to interest expense over the
life of the agreements. Termination gains or losses of such derivatives are
amortized to interest expense over the remaining life of the hedged transaction.

       When a derivative no longer fulfills the high correlation objective, it
is accounted for on a mark-to-market basis and termination of such derivatives
is recognized immediately in the Statement of Income as a component of interest
expense.

NET INCOME PER LIMITED PARTNERSHIP UNIT is computed by dividing the net income
allocated to the Limited Partners by the weighted average units outstanding
(4,625,000).

2. FINANCE LEASES

As of December 31, 1998, the Partnership owns seven aircraft which are all
leased under finance leases. Five of the aircraft are leased to US Airways, Inc.
In 1998, at the end of the initial 12-year term, US Airways, Inc. exercised its
option to renew the lease for an additional three years, which renewal period
was included in the original lease term for accounting under the generally
accepted accounting principals. In 1998, 1997, and 1996, leases with US Airways,
Inc. resulted in finance lease revenues of $6,498,000, $7,058,000, and
$7,559,000, respectively.

The sixth aircraft, wholly owned by the Partnership since January 31, 1997 when
it purchased USL Capital's 50% interest in this aircraft for $5.7 million, is
leased to Trans World Airlines (TWA) under a finance lease expiring in 2002. In
1998, 1997, and 1996 this lease with TWA, resulted in finance lease income of
$1,432,000, $1,463,000, and $697,000, respectively.

The seventh aircraft is leased to Federal Express Corporation (FedEx) under a
13-year finance lease which expires in 2006. In 1998, 1997, and 1996 this lease
with FedEx resulted in finance lease income of $470,000, $507,000, and $544,000,
respectively.

The finance leases at December 31, 1998 and 1997, are summarized as follows (in
thousands):

</TABLE>

Residual valuation, which is reviewed annually, represents the estimated amount
to be received from the disposition of aircraft after lease termination. If
necessary, residual adjustments are made which result in an immediate charge to
earnings and/or a reduction in earnings over the remaining term of the lease.

Finance lease receivables at December 31, 1998 are due in installments of
$15,548,000 annually through 2000, $12,589,000 in 2001, $1,710,000 in 2002,
$1,310,000 in 2003, and $3,274,000 thereafter.

3. OPERATING LEASES

At December 31, 1998, the Partnership did not own any aircraft subject to an
operating lease. The last aircraft that was subject to an operating lease was
sold in September 1997.

4. LONG-TERM NOTES PAYABLE

As of December 31, 1998 and 1997 long-term notes payable included the following:

            An 8.75% non-recourse note payable to a bank collateralized by three
            aircraft leased to US Airways, Inc. This note was paid in full in
            1998. At December 31, 1997 the note's outstanding balance was
            $3,589,000.

            A 7.4% non-recourse loan facility collateralized by the aircraft
            leased to FedEx, due in semi-annual installments of $451,000 through
            April 2006. At December 31, 1998 and 1997, $5,098,000 and
            $5,589,000, were outstanding, respectively.

            A 9.35% non-recourse loan facility collateralized by the aircraft
            leased to TWA, due in monthly installments of $150,000 through March
            2002. At December 31, 1998 and 1997, $5,150,000 and $8,189,000, were
            outstanding, respectively. During 1998, the Partnership renegotiated
            the terms of the 9.35% loan facility. As part of the re-negotiation,
            the Partnership was able to prepay $2.0 million in principal and
            reduce the interest rate 50 basis points from 9.85% to 9.35%.

            A non-recourse revolving variable rate loan facility, which was
            collateralized by one of the aircraft leased to US Airways, Inc. At
            December 31, 1998 no balance was outstanding as the loan facility
            expired earlier in the year. At December 31, 1997, $1,748,000 was
            outstanding. The Partnership held an interest rate swap agreement,
            which effectively fixed the interest rate on this non-recourse
            facility at 7.36% through the date the debt expired.



                                      A-9
<PAGE>   42



            A $7.5 million three-year revolving loan facility obtained in
            February 1998. The facility was initially collateralized by one
            aircraft on lease to US Airways, Inc., was guaranteed by the
            Partnership, and bore an interest rate of three-month Libor plus 225
            basis points. In December 1998, this loan facility was expanded by
            $5.0 million and the variable interest rate was lowered to 212.50
            basis points over the three-month Libor when another plane leased to
            US Airways was added as additional collateral. At December 31, 1998,
            $4,257,000 was outstanding and approximately $6,500,000 was
            available under this facility.

Based upon amounts outstanding at December 31, 1998, the minimum future
principal payments on all outstanding fixed-rate long-term notes payable are due
as follows (in thousands):

The carrying amounts presented in the table are included in the balance sheet
under the indicated captions.

The following notes summarize the major methods and assumptions used in
estimating the fair values of financial instruments:


     LONG-TERM DEBT is estimated by discounting the future cash flows using
     rates that are assumed would be charged to the Partnership for debt with
     similar terms and remaining maturities.

     DERIVATIVES are estimated as the amount that the Partnership would receive
     or pay to terminate the agreements at the reporting date, taking into
     account current market interest rates and corresponding borrowing spreads.

7. TRANSACTIONS WITH THE GENERAL PARTNER AND AFFILIATES

In accordance with the Agreement of Limited Partnership, the General Partner and
its affiliates receive expense reimbursement, fees and other compensation for
services provided to the Partnership.

Amounts earned by the General Partner and affiliates for the years ended
December 31, 1998, 1997, and 1996, were as follows (in thousands):

The General Partner was allocated its 1% share of the Partnership net income and
cash distributions. Holding and BALCAP, each a limited partner and an affiliate
of the General Partner, were also allocated their share of income and cash
distributions.

8. FEDERAL INCOME TAX STATUS

The Partnership is considered a publicly traded Partnership ("PTP") under the
Revenue Act of 1987. Under that Act, the Partnership was not subject to federal
income tax as a Partnership until 1998. Effective January 1, 1998, PTP's were
required to choose to retain PTP status and be 



                                      A-11
<PAGE>   44

subjected to federal income tax as a corporation or to delist their units
thereby removing themselves from the scope of the PTP rules. Faced with these
alternatives, the Partnership initially recommended that its units be delisted.

In August and October 1997, respectively, federal and California tax laws were
amended to provide PTP's a third alternative. Under these amended laws, PTP's
are allowed to continue to be publicly traded during 1998 and subsequent years
without becoming subject to corporate income tax if they elect to pay a 3.5%
federal tax and a 1% California tax on gross income.

The board of directors of the General Partner unanimously concluded, after
authorization from the unitholders and consideration of a number of factors,
including the 1997 tax law changes and the benefits of liquidity, that is was in
the best interests of the unitholders for the Partnership to remain publicly
traded at that time. Accordingly, in January 1998 the Partnership made an
election to pay the annual 4.5% gross income tax at the Partnership level. Gross
income includes both earned lease finance income ($8,400,000 in 1998) and
receipts in excess of earned finance income ($7,147,000 in 1998) as well as
dispositions from the sale of property.

9. RECONCILIATION TO INCOME TAX METHOD OF ACCOUNTING

The aircraft on lease to US Airways, Inc. were purchased subject to a tax
benefit transfer lease ("TBT") which provided for the transfer of Federal income
tax ownership of these aircraft to a tax lessor until 1991. The transfer was
accomplished by the sale, for tax purposes only, of the aircraft to the tax
lessor for cash and a note and a leaseback of the aircraft for rental payments
which equalled the payments on the note. The rental payments resulted in tax
deductions and the interest was included in taxable income. In 1991, the TBT
lease agreement terminated and the tax attributes transferred under the TBT
lease reverted to the Partnership.

The difference between the method of accounting for income tax reporting and the
method of accounting used in the accompanying financial statements are as
follows (in thousands except per unit amounts):

SECTION 4. REPAYMENT AND PREPAYMENT

                  4.1 Principal. (a) On each Payment Date, Borrower shall repay
the outstanding principal amount of the Loan in the amount by which the
outstanding Loan exceeds the Total Commitment on such Payment Date. Borrower
shall give Agent and each Lender not less than two Banking Days prior written
notice of each repayment pursuant to this Section 4.1(a), which notice shall
specify which Advances are being repaid in whole or in part and the amount of
each Advance being repaid.

                  (b) Without limiting any other provisions of the Financing
Documents requiring the scheduled or unscheduled repayment or prepayment of the
Loan, the principal balance of the Loan shall be repaid in full on the Maturity
Date or Extended Maturity Date, as applicable.

                  4.2 Interest. (a) Interest payable on each Advance during the
Commitment Period shall accrue from the Borrowing Date on which such Advance was
made until the principal amount of such Advance is repaid (whether


                                      -20-

<PAGE>   27

at maturity, on a date fixed for repayment or prepayment, by acceleration or
otherwise), shall be calculated at the Interest Rate and shall be calculated on
the basis of a year of 360 days for the actual days elapsed. Interest on each
Advance with respect to each Payment Period shall accrue from the first day of
such Payment Period to and including the last day of such Payment Period and
shall be payable in arrears on the last day of such Payment Period; provided,
that for any Advance not made on the first day of a Payment Period, Interest on
such Advance shall accrue from the Borrowing Date of such Advance to and
including the last day of the Payment Period in which such Advance was made and
shall be payable in arrears on the last day of such Payment Period.

                  (b) The "Interest Rate" for any Payment Period shall be equal
to the Base Rate with respect to such Payment Period plus the Margin; provided,
that for any Advance not made on the first day of a Payment Period, the
"Interest Rate" applicable to such Advance for the balance of such Payment
Period shall be equal to the sum of (i) a base rate of interest determined in
accordance with the definition of "Base Rate" for a period equal to the balance
of such Payment Period, plus (ii) the Margin.

                  (c) Interest shall accrue on any principal and, to the extent
permitted by law, on any interest and any other amounts owing under the
Financing Documents that are not paid within five days of the due date thereof
at the Overdue Rate in effect from time to time (computed on the basis of a year
of 360 days for the actual number of days elapsed) from the date on which such
principal, interest or other amount becomes due until paid, and overdue interest
shall be payable on demand. In addition, Borrower shall pay $150.00 for each
late payment.

                  (d) The rate of interest payable under the Financing Documents
shall not at any time exceed a rate that, when combined with any and all other
charges provided for in the Financing Documents (to the extent such other
charges would constitute interest for the purpose of any Applicable Law limiting
interest that may be charged) equals the maximum interest rate permitted by law
with respect to the transactions contemplated by the Financing Documents.

                  4.3 Mandatory Prepayments. (a) If an Event of Loss occurs with
respect to either Airframe and subject to the terms of Section 3.4 of the
Security Agreement, then on the earliest to occur of (i) 10 days after the date
of payment of insurance proceeds as a result of such Event of Loss of such
Airframe, (ii) the date of payment by Lessee of "Stipulated Loss Value" (as
defined in the Lease related to such Airframe), or (iii) 90 days after the date
of occurrence of the Event of Loss of such Airframe, an amount equal to 55% of
the outstanding principal amount of the Loan, all accrued and unpaid interest on
the Loan and any and all other fees and sums that are payable under the
Financing Documents, including any amounts required pursuant to Section 6.1,
shall be immediately due and payable and Agent shall deliver to Borrower a
replacement Schedule 1 and Schedule 2 reflecting a reduction by 55% of the Total
Commitment outstanding from time to time.

other amounts then payable by Borrower under the Financing Documents, including
any amounts required pursuant to Section 6.1, shall be immediately due and
payable and shall be paid in full by Borrower.

                  (c) If Lessee exercises its early termination option under

interest accrued and unpaid on the Loan and all other amounts then payable by
Borrower under the Financing Documents, including any amounts required pursuant
to Section 6.1, shall become immediately due and payable, and shall be paid in
full by Borrower, on the "Termination Date" (as such term is defined in Section
20.04(A) of such Lease) or on any earlier date on which the term of such Lease
ends pursuant to the penultimate sentence of Section 20.04(A) of such Lease.

                  4.4 Voluntary Termination of Commitments. On any date after
the first anniversary of the Closing Date, Borrower shall be entitled at its
option to terminate the Total Commitment in whole so long as (a) Borrower gives
five Banking Days written notice of such termination to Agent and the Lenders,
(b) on or before the date of such termination Borrower shall prepay the Loan
pursuant to and in accordance with Section 4.5, and (c) Borrower pays to Agent
on behalf of the Lenders the Commitment Termination Fee set forth in Section
12.4. Any such termination or reduction shall be permanent and irrevocable once
notice is given to Agent or any Lender.

                  4.5 Voluntary Prepayments. (a) Borrower may prepay all or any
portion of the Loan at any two times during each Payment Period (not including
any mandatory prepayment pursuant to Section 4.1(a) on a Payment Date and not
including any prepayment of principal in excess of the amount required pursuant
to Section 4.1(a) on a Payment Date if an amount of principal is required to be
prepaid on such Payment Date, but including any prepayment of principal on a
Payment Date if no principal is required to be prepaid on such Payment Date
pursuant to Section 4.1(a) above) by giving Agent and each Lender not less than
five Banking Days prior written notice (the "Prepayment Notice") of Borrower's
intention to prepay, which notice shall specify the date of prepayment (the
"Prepayment Date"), which Advances are being prepaid in whole or in part and the
amount of each Advance being repaid. In the event that the portion of an Advance
to be prepaid is not prepaid on the designated Prepayment Date, Borrower shall
be entitled to reschedule such prepayment to another Banking Day by at least one
Banking Days' prior telephonic or telefaxed notice to Agent and each Lender, and
Borrower may revoke the Prepayment Notice at any time by delivering to Agent and
each Lender written notice of revocation. In the event that a Payment Period
ends at any time after the receipt by Lender of the Prepayment Notice but before
the prepayment by Borrower pursuant to the Prepayment Notice, a series of
consecutive one day Payment Periods shall ensue for the portion of the Advance
designated to be prepaid beginning immediately after the end of the Payment
Period during which the Prepayment Notice was given and continuing until the
earlier of (i) the prepayment of such portion of such Advance or (ii) the next
Payment Date, and the Interest Rate for each such one-day Payment Period shall
equal each Lender's


                                      -22-

overnight borrowing costs for funds plus the Margin. Notwithstanding the
foregoing, to the extent the portion of any Advance designated to be prepaid is
not prepaid by Borrower by the next Payment Date, the Prepayment Notice shall be
deemed to be revoked and the provisions of Section 4.2 shall apply to the
Payment Period beginning on the next Payment Date.

                  (b) Any prepayment of all or any portion of the principal of
the Loan under this Section 4.5 shall be made together with accrued interest on
the portion of the Loan being prepaid through the date of such prepayment and
all fees and expenses of Agent and each Lender due and payable pursuant to the
Financing Documents, including any amounts due pursuant to Section 6.1.

                  Section 4.6(a); and

                           (ii) all payments received and amounts realized by
                  Agent under each Lease or otherwise with respect to the
                  Equipment to the extent received or realized at any time after
                  payment in full of the principal of, interest and amounts due
                  under Section 6.1, if any, and all other amounts due to Agent
                  and the Lenders under this Agreement or any other Financing
                  Document as well as any other amounts remaining as part of the
                  Collateral after payment in full of the principal of,

                  interest and amounts due under Section 6.1, if any, and all
                  other amounts due to Agent and the Lenders under this
                  Agreement or any other Financing Document shall be distributed
                  to Borrower.

                  (g) Distribution of Excluded Amounts. All amounts constituting
Excluded Amounts received by Agent or any Lender shall be paid by Agent or such
Lender to the Person or Persons entitled thereto.

                  4.7 Application of Payments. All payments required to be made
by Borrower under the Financing Documents, when received by Agent, shall be
applied (a) first, to pay any fees and expenses payable by Borrower to Agent and
the Lenders under the Financing Documents, including expenses incurred in
exercising remedies under the Security Agreement, (b) second, to accrued and
unpaid interest with respect to the Loan, and (c) third, to the payment of any
principal amount of the Loan then due.

SECTION 5. PAYMENTS

                  5.1 Place and Manner of Payment. All payments required to be
made to Agent under the Financing Documents shall be made in Dollars by wire
transfer of immediately available funds to the account of Agent as follows:

                     Credit Lyonnais, New York
                     ABA No. 026008073
                     Account No. 01-22403-0001-00
                     In favor of:     PK AIRFINANCE NY
                                      CHIPS UID No. 357771
                     Reference:       USA71

or to such other  account in the  continental  United States of America as Agent
may  designate  from time to time by five Banking Days prior  written  notice to
Borrower.  Agent shall have no property  interest in the funds it receives  from
Borrower  for  distribution  to the Lenders,  but shall hold such funds  pending
disbursement  to the  Lenders  pursuant  to the  terms  of this  Agreement.  All
payments  required to be made to any Lender under the Financing  Documents shall
be made in  Dollars  by wire  transfer  of  immediately  available  funds to the
account  of such  Lender  set  forth  on such  Lender's  signature  page to this
Agreement or to such other account in the  continental  United States of America
as such  Lender  may  designate  from time to time by five  Banking  Days  prior
written notice to Agent and Borrower.

                  5.2 Payments on Banking Day. If any payment under the
Financing Documents is due on a date that is not a Banking Day, then such
payment shall be due and paid on the next succeeding day that is a Banking Day
and interest (calculated at the applicable interest rate in effect for the
Payment Period during which the original payment date occurred) shall be


                                      -26-

<PAGE>   33

payable on any principal whose payment was so extended and, to the extent that
such interest is so paid, it shall be credited against the interest payment due
on the next succeeding Payment Date; provided, that if such next succeeding
Banking Day occurs in the next calendar month, the payment shall be due on the
immediately preceding Banking Day.

                  5.3 No Offset. All payments by Borrower under the Financing
Documents shall be made when due without notice, demand, offset, counterclaim,
deduction or defense and without abatement, suspension, deferment, diminution or
reduction, whether by virtue of any claim that Borrower may now or hereafter
have against any Person.

SECTION 6. COMPENSATION FOR ADDITIONAL COSTS; INDEMNITIES

                  6.1 Compensation for Re-employment of Funds. Borrower shall
compensate each Lender, upon written request by such Lender, for all reasonable
losses, expenses and liabilities (including any losses and expenses incurred on
account of funds borrowed, contracted for or utilized for purposes relating to
the Loan or in connection with the reemployment or reinvestment of such funds or
an interruption of the use of such funds) that such Lender sustains as a result
of (a) the failure of Borrower to borrow any part of an Advance on the Borrowing
Date as set forth in a Borrowing Notice, (b) the repayment or prepayment of any
portion of the Loan (including as a result of the exercise by Agent or any
Lender of its remedies following the occurrence of an Event of Default, or as a
result of this Section 6) on any date other than a Payment Date, or (c) the
failure of Borrower to prepay the Loan on a Prepayment Date that is rescheduled
on less than three Banking Days prior written notice. Compensation to any Lender
under this Section 6.1 shall include an amount equal to any and all interest,
break-funding costs and other amounts payable by such Lender to providers of
funds obtained by such Lender in order to make, maintain or renew its
Commitment, and costs incurred by such Lender in redeploying funds that were to
be used by it to make, maintain or renew its Commitment. Agent and each Lender
will use reasonable efforts to minimize any loss, cost or expense for which they
are entitled to compensation under this Section 6.1; provided that the foregoing
undertaking shall not obligate any Lender to take any steps adverse to its
business, financial or commercial interest as reasonably determined by such
Lender.

                  6.2 Force Majeure. Neither Agent nor any Lender shall be held
responsible for any loss or damage arising out of any action taken or omitted by
Agent or any Lender or to which Agent or any Lender becomes subject resulting
from a mandatory legal enactment, any measure of a Governmental Body or public
authority, a war, strike, boycott or blockade or any other cause reasonably
beyond its control.

                  6.3 Illegality. In the event that in the reasonable judgment
of any Lender, the making or maintaining of any portion of such Lender's
Commitment or the performance by Borrower of any obligation to be performed by
Borrower under the Financing Documents has become unlawful by


                                      -27-

<PAGE>   34

reason of any change after the date of this Agreement in any Applicable Law,
then such Lender shall promptly notify Agent and Borrower of such illegality. To
the extent that any portion of the Commitment of such Lender has not been
borrowed by Borrower at that time, the obligation of such Lender pursuant to
Section 2 to lend the remaining portion of its Commitment shall terminate. If
the full Commitment of such Lender has been loaned to Borrower, within 30 days
after receipt of such notice or any later date permitted by Applicable Law,
Borrower shall repay the principal amount of the Notes held by such Lender, all
interest accrued on such principal amount, all other sums then due and payable
under the Financing Documents (including amounts payable pursuant to Section
6.1).

                  6.4 Additional Funding Costs. In the event that any Applicable
Law, whether in effect on the date of this Agree- ment or hereafter, any change
in Applicable Law or the compliance by any Lender with any presently effective
or future request or directive (whether or not having the force of law) from any
Government Body:

                           (a subjects such Lender to any Tax, levy, impost,
                  duty, charge, fee, deduction, withholding restriction or
                  condition of any kind with respect to the Financing Documents
                  or the Loan (other than income Taxes paid by such Lender in
                  the jurisdiction in which it is incorporated or in which the
                  lending office making the Loan is located), or to a change in
                  the basis of taxation of payments to such Lender of principal,
                  interest, fees or any other amount payable under the Financing
                  Documents (other than the rates of income taxation to which
                  such Lender is subject),

                           (b imposes or makes applicable any reserve or similar
                  requirement against assets held by, or liabilities in or for
                  the account of, advances or loans by, other credit extended by
                  or any other acquisition of funds by such Lender, or

                           (c imposes on such Lender any other condition
                  affecting the Advances (other than the rates of income
                  taxation to which such Lender is subject),

and the result is to increase the cost to such Lender of making, renewing or
maintaining its portion of the Loan or to reduce or delay the receipt by such
Lender of any amount receivable under the Financing Documents, then, in any such
case, Borrower shall promptly pay to such Lender upon its demand such additional
amount necessary to compensate such Lender for such additional cost (net of any
Tax savings realized by such Lender) or the reduction of or delay in receiving
any amount so receivable. Upon the request of Borrower, such Lender shall
deliver to Borrower a certificate setting forth the basis for the determination
of such amount necessary to compensate such Lender.

                  6.5 General Tax Indemnity. (a) All payments made by Borrower
to Agent or any Lender under the Financing Documents shall be made free and
clear of, and without deduction for or on account of, any Tax, other than


                                      -28-

<PAGE>   35

                           (i) any Tax imposed because of a present or former
                  connection between the jurisdiction of the Government Body
                  imposing such Tax and Agent or such Lender other than a
                  connection arising from Agent or such Lender having executed,
                  delivered or performed its obligations under the Financing
                  Documents, received a payment under the Financing Documents or
                  enforced any Financing Document;

                           (ii) Taxes imposed on or with respect to, based on or
                  measured by the net income, gross income, receipts, capital or
                  net worth of Agent or such Lender by any Government Body in
                  any jurisdiction in which Agent or such Lender is
                  incorporated, has its principal place of business or is
                  subject to such Taxes by reason of transactions or activities
                  unrelated to those contemplated by the Financing Documents
                  (except there shall not be excluded any such Taxes in the
                  nature of or imposed in lieu of sales, use, excise or similar
                  taxes); and

                           (iii) any Tax that would not have been imposed but
                  for such Lender's failure to comply with the provisions of
                  Section 6.5(c).

(collectively, and excluding the Taxes set forth in the preceding clauses (i)
through (iii), the "Indemnified Taxes"). If any Indemnified Taxes are required
to be withheld or deducted from any amounts payable to Agent or any Lender under
the Financing Documents, Borrower shall pay to Agent or such Lender an
additional amount that (after subtraction of all such Indemnified Taxes and any
Taxes incurred by reason of the payment or receipt of such additional amount)
will be sufficient to yield to Agent or such Lender such amounts payable. Within
15 days after the date of each payment of Indemnified Taxes to a Governmental
Body, Borrower shall furnish to Agent and any applicable Lender the original or
a certified copy of a receipt or other evidence of the payment of such
Indemnified Taxes. If Agent or any Lender determines in good faith that any
Indemnified Taxes are payable in respect of any payments under any Financing
Document, Agent or such Lender may (but is not obligated to) pay such
Indemnified Taxes, and Borrower shall promptly pay to Agent or such Lender, on
demand, an amount that will be sufficient to yield to Agent or such Lender
(after subtraction of any Taxes incurred by reason of the receipt of such
payment) the amount of such Indemnified Taxes.

                  (b In the event any claim shall be made against Agent or any
Lender for any Indemnified Taxes for which Borrower might be liable under this
Section 6.5, Agent or such Lender shall use its best efforts to notify Borrower
of such claim and shall consult in good faith with Borrower concerning such
claim. If requested by Borrower, Agent or such Lender shall contest such claim
at the sole cost and expense of Borrower; provided, that Agent or such Lender
shall have no obligation to contest any such claim if, in its reasonable
opinion, to do so would be prejudicial to its overall tax interest. If Agent or
such Lender shall receive a refund of any Indemnified Tax that was paid or
indemnified by Borrower under this Section 6.5, then so long as no Event of
Default has occurred and is continuing, Agent or such Lender shall promptly pay
to Borrower (i) the amount of such refund, (ii) the amount of any Tax savings
actually realized from such payment (as determined by Agent or such


                                      -29-

<PAGE>   36

Lender in its sole good faith discretion,  it being understood that Borrower has
no right to inspect  the tax returns or records of Agent or such  Lender),  and 
(iii) any interest received in respect of such refund.

                  (c Each Lender that is not incorporated in a jurisdiction of
the United States of America shall deliver to Borrower such certificates,
documents or other evidence as may be reasonably requested by Borrower from time
to time, including any certificate or statement of exemption required by United
States Treasury Regulation Section 1.1441-4(a) or Section 1.1441-6(c), completed
and duly executed by such Lender, to establish that payments of interest on the
Loan to such Lender and any other payment required by any Financing Document to
such Lender are exempt from or are subject to a reduced rate of withholding of
Tax imposed by any Government Body.

                  6.6 Mitigation.(a) In the event that any Lender exercises its
rights pursuant to Section 6.4 to require compensation from Borrower, then such
Lender and Borrower will attempt to restructure such Lender's portion of the
Loan to eliminate the increased costs and continue such Lender's portion of the
Loan, and Borrower shall remain liable for all increased costs during any period
of time in which such Lender and Borrower are attempting to restructure such
portion of the Loan. If such Lender and Borrower are unable to restructure such
Lender's portion of the Loan, upon five Banking Days prior written notice to
such Lender, Borrower may repay such Lender's principal portion of the Loan
together with all interest accrued on such principal and all other amounts
payable to such Lender under the Financing Documents, including any amounts
payable under Section 6.1 within 60 days from the date such Lender notified
Borrower of such increased costs.

                  (b In the event any amounts are required to be with- held or
deducted from any amounts payable to Agent or any Lender under the Financing
Documents, Borrower and Agent or such Lender shall consult in good faith and
shall each use its best efforts to restructure the transactions contemplated by
the Financing Documents in order to avoid such withholding or deduction;
provided, that Agent and such Lender shall be reimbursed by Borrower for all
costs incurred in connection with such restructuring and shall not be required
to take any action or agree to any restructuring that Agent or such Lender
determines in good faith is or may be detrimental to it. In the event Agent or
such Lender becomes liable for any Taxes (other than Indemnified Taxes), Agent
or such Lender may, at its expense, take such action (including a transfer of
its interest in the Loan or any of the Financing Documents to one or more
Affiliates) as Agent or such Lender may determine will avoid or minimize such
Taxes; provided, however, that no such action shall materially increase the
obligations or diminish the rights of Borrower under the Financing Documents.

                  6.7 General Indemnity. Borrower hereby indemnifies each
Indemnitee and agrees to hold each Indemnitee harmless against any and all
reasonable liabilities, damages, losses, claims, costs and expenses (excluding
any taxes, fees or other charges on, based on, or measured by the gross or net
receipts or the gross or net income of any Lender, or any business


                                      -30-

<PAGE>   37

or similar taxes, any transfer taxes and Taxes for which a Lender is otherwise
indemnified pursuant to Section 6.5), and to reimburse such Indemnitee for any
reasonable legal or other fees or expenses, incurred by it in connection with,
arising out of or resulting from (a) any claim or defending or prosecuting any
action or proceeding relating to the Financing Documents, (b) any Default, Event
of Default, breach of warranty by Borrower, material misrepresentation by
Borrower or non-performance by Borrower of any of its covenants or obligations
under any Financing Document, (c) any Lease Default, Lease Event of Default,
breach of warranty by Lessee, misrepresentation by Lessee or non-performance by
Lessee of any of its covenants or obligations under any Transaction Document, or
(d) the possession, delivery, registration, maintenance, condition, service,
repair, overhaul, use or operation of the Equipment whether or not attributable
to any defect in the Equipment or to its design, testing, use or otherwise;
provided, that Borrower shall have no obligation to indemnify or hold harmless
any Indemnitee for any liabilities, damages, losses, claims, costs or expenses
resulting from any Indemnitee's gross negligence or wilful misconduct or the
breach of any representations, warranties or covenants of the Lenders set forth
herein; provided that prior to making any claim against Borrower under this
Section 6.7 such Indemnitee shall have made demand of Lessee for indemnity as to
any claim or expense indemnified against by Lessee under the Lease; and
provided, that Borrower shall have no liability under this Section 6.7 for
principal, interest and amounts payable pursuant to Section 6.1, 12.1, 12.2,
12.3 or 12.5, which payments are subject to the provisions of Section 2.7.

SECTION 7. BORROWER'S REPRESENTATIONS AND WARRANTIES

                  Borrower represents, warrants and covenants to Agent and each
Lender on the date of this Agreement, on the Closing Date, the Additional
Commitment Closing Date and at all times during the Commitment Period as
follows:

                  7.1 Organization; Power. Borrower (a) is a duly formed and
validly existing trust, (b has full power to enter into, legally bind itself by
and perform its obligations under the Financing Documents, and (c) has complied
with all material statutory and other requirements relating to the business
carried on by it.

                  7.2 Citizenship. Borrower is and will remain a "citizen of the
United States" as defined in Section 40102(a)(15) of the Aviation Law for
purposes of permitting FAA registration of the Airframe pursuant to Section
44103 of the Aviation Law.

                  7.3 Trust Authority. The execution, delivery and performance
by Borrower of the Financing Documents, the borrowing and the giving of security
by Borrower as provided in the Financing Documents and the execution, delivery
and performance of each other agreement or instrument contemplated by the
Financing Documents by Borrower have been duly authorized by all necessary trust
action on the part of Borrower, do not require any approval from Guarantor, as
beneficiary under the Trust Agreement (except as has been


                                      -31-

<PAGE>   38

obtained), or approval or consent of any trustee or holders of any Debt or
obligations of Borrower (or any such required approvals and consents have been
or before the Closing Date and Additional Commitment Closing Date, as
applicable, will be duly obtained), will not violate any provision of the Trust
Agreement or other governing documents and will not result in the breach of,
constitute a default under, contravene any provision of or result in the
creation of any Lien (other than Permitted Liens) upon the Trust Estate or any
of its other property or assets pursuant to, any agreement, indenture, mortgage,
note, lease or other agreement or instrument to which Borrower is a party or by
which Borrower or its property may be bound or affected.

                  7.4 Consents. All necessary consents, resolutions and
authorizations for Borrower to enter into the Financing Documents have been
obtained, and no further consents or authorizations are necessary for the
repayment of the Loan pursuant to the provisions of this Agreement and the Notes
or for the performance by Borrower of its obligations pursuant to the Financing
Documents.

                  7.5 Enforceable Agreement. Each of the Financing Documents to
which Borrower is a party constitutes the legal, valid and binding agreement of
Borrower, enforceable against Borrower in accordance with its terms, except as
such enforceability may be limited by applicable bankruptcy, insolvency or other
laws affecting creditors' rights in general and principles of equity.

                  7.6 Compliance with Applicable Law. The execution, delivery
and performance of the provisions of the Financing Documents to which Borrower
is a party and the consummation of the transactions contemplated by the
Financing Documents by Borrower do not and will not, during the Commitment
Period, contravene in any material respect any Applicable Law.

                  7.7 Litigation. No judgments are outstanding against Borrower
and, to the knowledge of Borrower, no action, claim, suit or proceeding is
pending or threatened (including tax liens and tax actions) against or affecting
Borrower before any court, board or arbitration or administrative agency that
will result in the inability of Borrower to perform its obligations under the
Financing Documents.

                  7.8 No Taxes. No taxes are required to be paid under the laws
of the United States or any other jurisdiction in which Borrower conducts
business in connection with the execution, delivery or performance of the
Financing Documents, except taxes that Borrower shall have paid on or before the
Closing Date and Additional Commitment Closing Date, as applicable.

                  7.9 No Stamp Taxes. Neither the Financing Documents nor any
filing required or permitted under the Financing Documents is subject to any
registration tax, any stamp duty or any similar tax (other than those
registration taxes, stamp duties or similar taxes that Borrower shall have


                                      -32-

<PAGE>   39

paid on or before the Closing Date and Additional Commitment Closing Date, as
applicable).

                  7.10 Title to Collateral. On the Closing Date, the Additional
Commitment Closing Date and throughout the Commitment Period, Borrower will have
good and marketable title to, and will be the sole owner of and have the right
to possess, the Equipment, the Technical Records and all other Collateral, free
and clear of all Liens except for Permitted Liens and the beneficial ownership
of Guarantor under the Trust Agreement. Borrower warrants, at its sole expense,
to defend the title to and possession of the Collateral against the claims and
demands of all Persons whomsoever except claims and demands under Permitted
Liens, and to keep at all times the Lien of the Security Agreement a first
priority Lien on the Collateral as constituted from time to time, superior to
the rights of all third parties to the extent permitted by Applicable Law.
Borrower shall obtain any authorization, approval, license, or consent of any
Governmental Body (including registration of each Airframe with the FAA's
Aircraft Registry) that is or may become necessary or is reasonably requested by
Agent in order to obtain the full benefits of all rights and powers granted to
Agent and any Lender in the Financing Documents.

                  7.11 No Liens. No security agreement, financing statement,
equivalent security or lien instrument or continuation statement or other Lien,
whether voluntary or involuntary, covering all or any part of the Collateral has
been placed on file or of record by Borrower with any Governmental Body or is
otherwise in effect with respect to the Collateral except such as may have been
filed by Borrower pursuant to the Security Agreement and for Permitted Liens.

                  7.12 No Default. Borrower is not in default under any
agreement to which it is a party or by which it may be bound, and is not in
default of any kind in respect of any financial commitment or obligations
(including obligations under guarantees) that, in either case, could have a
material adverse affect on the ability of Borrower to perform its obligations
under the Financing Documents.

                  7.13 Material Disclosure. No written information given by
Borrower to Agent or any Lender in connection with the transactions contemplated
by the Financing Documents contained any untrue statement of material fact or
omitted to state a material fact that is adverse to the interest of Agent or any
Lender or that would be necessary to make any statement previously given by
Borrower or any representation or warranty contained in the Financing Documents
not misleading.

                  7.14 Principal Place of Business. The principal place of
business and chief executive office of Borrower are located either (a) at 35
North Sixth Street, Reading, Pennsylvania 19601, or (b) at the address set forth
in Section 16.2, and Borrower has not maintained a principal place of business
or chief executive office anywhere else in the past five years. The office where
Borrower keeps its records concerning the Collateral is located at the address
set forth in Section 16.2.


                                      -33-

<PAGE>   40

                  7.15 Trade Names. Borrower does not transact or do business
under any assumed name, trade name or fictitious name.

                  7.16 No Duty to Investigate. The rights and remedies of Agent
and the Lenders under the Financing Documents in relation to any
misrepresentation or breach of warranty on the part of Borrower under the
Financing Documents shall not be prejudiced by any lack of investigation by or
on behalf of Agent or any Lender into the affairs of Borrower, the Trust
Company, Guarantor or Lessee, by the performance of this Agreement or by any
other act or thing which may be done by Agent or any Lender in connection with
the Financing Documents and that would, apart from this Section 7.16, prejudice
such rights or remedies.

                  7.17 Trust Agreement. The Trust Agreement and the certificates
issued pursuant to the Trust Agreement constitute the entire agreement with
respect to the creation of the trust holding the Trust Estate and the Trust
Agreement is in full force and effect and has not been amended, modified or
supplemented except as specifically evidenced by the amendments, modifications

subject to the jurisdiction of a bankruptcy court and Agent and the Lenders, as
a result, are prevented by any order of such court or by operation of any law

enforcement of any rights granted to the Lenders and Agent under any Financing
Document and the Additional Commitment Documents.

                  12.2 Up-front Fee. Borrower (i) paid to Agent on the Closing
Date a fee in the amount of $80,000, and (ii) shall pay to Agent on the
Additional Commitment closing date an additional one-time fee in the amount of
$50,000.

                  12.3 Credit Approval. (a) Agent acknowledges receiving on
behalf of the Lenders a fee in the amount of $50,000 (the "Credit Approval
Fee"), which Borrower acknowledges was the property of the Lenders and not
subject to any claim or interest of Borrower or Guarantor as beneficiary under
the Trust Agreement except to the extent set forth in this Section 12.3(a).

                  (b) Agent acknowledges receiving on behalf of the Lenders a
fee in the amount of $25,000 (the "Additional Credit Approval Fee"), which
Borrower acknowledges is the property of the Lenders and not subject to any
claim or interest of Borrower or Guarantor as beneficiary under the Trust
Agreement except to the extent set forth in this Section 12.3(b). Agent and the
Lenders agree that on the Additional Commitment Closing Date, upon consummation
by Borrower, the Trust Company and Guarantor of the transactions contemplated by
the Additional Commitment Documents, Agent shall pay the Additional Credit
Approval Fee to Borrower on behalf of the Lenders. Borrower agrees that if
Borrower, the Trust Company, Guarantor and Lessee, or any of them, fail to
consummate the transactions contemplated by the Additional Commitment Documents
on the Additional Commitment Closing Date, the Lenders shall be entitled to
retain the Additional Credit Approval Fee free and clear of any claims by
Borrower or Guarantor.

                  12.4 Commitment Termination Fee. On any date on which the
Total Commitment under this Agreement is terminated, whether pursuant to Section
4.3, 4.4, 11.2 or otherwise (excluding, however, terminations pursuant to
Sections 4.3(a), 6.3 and 11.2 and any termination by Borrower pursuant to
Section 4.4 as a result of liability of Borrower arising under Section 6.4 or
6.5 that exceeds or will exceed, in the aggregate, $100,000 during the
Commitment Period), Borrower shall pay to Agent on behalf of the Lenders on the
date of such termination or reduction a commitment termination fee (the
"Commitment Fee") equal to (a) on or before September 30, 1999, 1.0% of the
amount of the Total Commitment immediately before termination, and (b) on or
after October 1, 1999, 0.5% of the amount of the Total Commitment immediately
before termination.

                  12.5 Commitment Fee. (a) Borrower shall pay to Agent for the
account of each Lender a non-refundable commitment fee (the "Commitment Fee") on
the daily average amount of the Unused Commitment for each Payment Period during
the Commitment Period at an annual rate equal to the following formula:

                            0.01875 - 0.0025(OL / UC)

where "OL" is the average  principal amount of the Loan outstanding  during such
Payment  Period  and "UC" is the  Unused  Commitment  for such  Payment  Period;
provided, that if the preceding formula yields a negative number, the Commitment
Fee for such Payment Period shall be zero.

                  (b) The accrued Commitment Fee shall be payable quarterly in
arrears on each Payment Date for the Payment Period then ending and, in the
event Total Commitment is terminated, on the effective date of such termination.

                  12.6 Extension Fee. Upon the exercise by Borrower of its
option to extend the Commitment Period pursuant to Section 2.8 hereof, Borrower
shall pay to Agent a one-time non-refundable fee in the amount of $20,000.

SECTION 13. AGENT

                  13.1 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes Agent to act as its agent under the
Financing Documents with such powers as are specifically delegated to Agent by
the terms of the Financing Documents, together with such other powers as are
reasonably incidental to such delegated powers. Agent shall have no duties or
responsibilities except those expressly set forth in the Financing Documents and
shall not be a trustee for any Lender. Agent shall not be responsible to the
Lenders (a) for any recitals, statements, representations or warranties
contained in the Financing Documents, in any certificate or other document
referred to or provided for in, or received by any of them under, the Financing
Documents, (b) for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of the Financing Documents or any other document
referred to or provided for in the Financing Documents, (c) for the
collectibility of the Loan, (d) for the validity, effectiveness or value of any
interest or security covered by the Security Agreement, (e) for the value of the
Collateral, (f) for the validity or effectiveness of any assignment, mortgage,
pledge, security agreement, financing statement, document or instrument or for
the filing, recording, re-filing, continuing or re-recording of any thereof, or
(g) for any failure by Borrower or any other party to the Financing Documents to
perform any of its obligations under the Financing Documents, except that Agent
shall undertake to file continuation statements for the financing statements
filed naming Agent as secured party. In all its actions and duties, Agent may
employ agents and attorneys-in-fact and shall not be answerable, except as to
money or securities received by it or its authorized agents, for the negligence
or misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. Neither Agent nor any of its directors, officers, employees or
agents shall be liable or responsible for any action taken or omitted to be
taken by it or them under the Financing Documents or in connection with the
Financing Documents except for its or their own gross negligence or willful
misconduct.

                  13.2 Reliance by Agent. Agent shall be entitled to rely upon
any certification, notice or other communication (including by telephone, telex,
telegram or cable) believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper person or persons, and upon advice
and statements of legal counsel, independent accountants and other experts
selected by Agent. As to any matters not expressly provided for by the Financing
Documents, Agent shall in all cases be fully protected in acting, or in
refraining from acting, under the Financing Documents in accordance with
instructions signed by the Majority Lenders, and such instructions of the
Majority Lenders or other number of the Lenders as aforesaid and any action
taken or failure to act pursuant thereto shall be binding on all of the Lenders.

                  13.3 Events of Default. Agent shall not be deemed to have
knowledge of the occurrence of a Default unless Agent has received notice from a
Lender or Borrower specifying such Default and stating that such notice is a
"Notice of Default". In the event that Agent receives such a notice of the
occurrence of a Default, Agent shall promptly give notice of such Default to the
Lenders (and shall give each Lender notice of each such non-payment). Subject to
Section 13.6, Agent shall take such action with respect to such Default as shall
be directed by the Majority Lenders.


                                      -45-

<PAGE>   52

                  13.4 Indemnification of Agent. The Lenders shall indemnify
Agent (to the extent not reimbursed by Borrower, Trust Company, Guarantor or
Lessee pursuant to the Financing Documents) ratably in accordance with the
aggregate principal amount of the Commitments of the Lenders for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever imposed on,
incurred by or asserted against Agent in any way relating to or arising out of
(a) the Financing Documents, (b) any other documents contemplated by or referred
to in the Financing Documents, (c) the transactions contemplated by or referred
to in the Financing Documents (including the costs and expenses that Borrower is
obligated to pay under Section 12 but excluding, unless a Default has occurred
and is continuing, normal administrative costs and expenses incident to the
performance of its agency duties under the Financing Documents), or (d) the
enforcement of any of the terms of the Financing Documents or of any other
documents, provided that no Lender shall be liable for any of the foregoing to
the extent they arise from the gross negligence or willful misconduct of Agent.

                  13.5 Non-Reliance on Agent and other the Lenders. (a) Each
Lender agrees that it has, independently and without reliance on Agent or any
other Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of Borrower and its own decision to
enter into this Agreement, and that it will, independently and without reliance
upon Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Financing Documents.

                  (b) Agent shall not be required to keep itself informed as to
the performance or observance by Borrower of the Financing Documents or to
inspect the properties or books of Borrower. Except for any notices, reports and
other documents and information expressly required to be furnished to the
Lenders by Agent under the Financing Documents, Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of Borrower, Guarantor
or Lessee that may come into the possession of Agent.

                  13.6 Failure to Act. Except for action expressly required of
Agent under the Financing Documents, Agent shall in all cases be fully justified
in failing or refusing to act under the Financing Documents unless it shall be
indemnified to its satisfaction by the Lenders against any and all liabilities
and expenses that may be incurred by it by reason of taking or continuing to
take any such action.

                  13.7 Resignation or Removal of Agent. Subject to the
appointment and acceptance of a successor Agent as provided in this Section
13.7, Agent may resign at any time by giving not less


                                      -46-

<PAGE>   53

than 10 days prior written notice to the Lenders and Borrower. Agent may be
removed at any time for cause by the Majority Lenders, and may be removed at any
time without cause by the affirmative vote of all the Lenders. Upon any such
resignation or removal, the Majority Lenders shall appoint a successor Agent,
which with the consent of all the Lenders may be a Lender and which, if the
successor Agent is not a Lender, shall require the consent of Borrower, such
consent not to be unreasonably withheld or delayed. If no successor Agent is
appointed by the Lenders and accepts such appointment within 30 days after the
resigning Agent's notice of resignation or the Lenders' removal of the previous
Agent, then the resigning or removed Agent may, on behalf of the Lenders, after
consultation with Borrower, appoint a successor Agent. Upon the acceptance of
any appointment as Agent under the Financing Documents by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Financing
Documents. Borrower, the Lenders and the retiring Agent shall, at Borrower's
expenses, thereupon execute, deliver and file financing statement amendments
reflecting such change. After any retiring Agent's resignation or removal as
Agent, the provisions of this Section 13 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

SECTION 14. CERTAIN MATTERS CONCERNING THE LENDERS

                  14.1 Pro Rata Treatment Among the Lenders. Except as otherwise
provided in the Financing Documents, (a) each borrowing from the Lenders under
Section 2.1 will be made from the Lenders and each payment of the Commitment
Fee, Commitment Termination Fee and the Commitment Extension Fee shall be made
for the account of the Lenders pro rata according to their respective
Commitments, and (b) each payment and prepayment of principal of or interest on
the Loan will be made to Agent for the account of the Lenders pro rata according
to their respective Commitments.

                  14.2 Sharing of Collateral and Payments. In the event that at
any time any Lender shall obtain payment in respect of a Note or interest on the
Loan, or receive any collateral in respect of any portion of the Loan, whether
voluntarily or involuntarily, in a greater proportion than any such payment
obtained by any other Lender in respect of the corresponding Note held by it or
interest thereon, then the Lender so receiving such greater proportionate
payment shall purchase for cash from the other Lenders such portion of each such
other Lender's outstanding loan, or shall provide such other Lenders with the
benefits of any such collateral or the proceeds thereof, as shall be necessary
to cause such Lender receiving the proportionate over-payment to share the
excess payment or benefits of such collateral or proceeds ratably with each of
the other Lenders, each of which shall have a Lien on its ratable portion of the
amount described hereinafter obtained from Borrower; provided, however, that if
all or any portion of such excess payment or benefits is thereafter recovered
from the Lender which received the proportionate over-payment, such purchase
shall be rescinded and the purchase price and benefits returned to the extent of
such recovery, but without interest.

                                      -47-

<PAGE>   54

                  14.3 Several Obligations. The failure of any Lender to make
any Advance to be made by it on a Borrowing Date shall not relieve the other
Lenders of their respective obligations to make their Advances on such Borrowing
Date, but no Lender shall be responsible for the failure of the other Lenders to
make Advances to be made by such other Lenders.

SECTION 15. REGISTRATION AND TRANSFER OF NOTES

                  15.1 Registration, Transfer and Exchange of Notes. Borrower
will maintain a register for the registration and transfer of the Notes. Subject
to Section 16.9, any Lender may transfer or exchange an outstanding Note for one
or more new Notes by surrendering such outstanding Note at the address of
Borrower set forth in Section 16.2, together with its written request for the
issuance of a new Note or Notes, specifying the authorized denomination or
denominations of the same and the name and address of the Person or Persons in
whose name or names the new Note or Notes are to be registered and payable.
Promptly upon receipt by Borrower of the foregoing, but subject to Section 16.9,
Borrower shall execute and deliver such new Note or Notes, in the aggregate
principal amount of and dated the same date as the outstanding Note surrendered,
in such denomination or denominations specified in the written request and
registered in and payable to such Person or Persons specified in such written
request; provided, that if more than one new Note is to be issued, the
denominations of all but one of such new Notes shall not be less than $100,000.
Borrower shall make a notation on each new Note of the amount of all payments of
principal theretofore made, or the date to which such payments have been made,
on the old Note or Notes in exchange for which such new Note has been issued and
the date to which interest on such old Note or Notes has been paid.

                  15.2 Mutilated, Destroyed, Lost or Stolen Notes15. If any Note
shall become mutilated or shall be destroyed, lost or stolen, Borrower shall,
upon the written request of the holder of such Note, execute and deliver in
replacement thereof, a new Note, payable in the same original principal amount
and dated the same date as the Note so mutilated, destroyed, lost or stolen.
Borrower shall make a notation on each new Note of the amount of all payments of
principal and premium, if any, theretofore made, or the date to which such
payments have been made on the Note so mutilated, destroyed, lost or stolen and
the date to which interest on such old Note has been paid. If the Note being
replaced has been mutilated, such Note shall be delivered to Borrower and shall
be canceled by it. If the Note being replaced has been destroyed, lost or
stolen, the Lender holding such Note shall furnish to Borrower an indemnity
agreement reasonably satisfactory to Borrower that holds Borrower harmless from
any loss, including claims for principal of and interest on the purportedly
destroyed, lost or stolen Note, together with the written statement, signed by a
duly authorized officer of such Lender, advising as to the destruction, loss or
theft of such Note.


                                      -48-

<PAGE>   55

                  15.3 Transferability of Note. Each Note shall be transferable
by the holder of such Note upon the terms set forth in Section 16.9 of this
Agreement. No transfer of a Note shall be valid unless and until a new Note or
Notes in the name of the transferee or transferees has been issued in accordance
with Section 15.1.

                  15.4 Validity of Substituted Note. All Notes executed and
delivered in substitution or exchange for any Note shall be the valid
obligations of Borrower, evidencing the same debt as the Note in exchange for
which they were executed and delivered, and shall be secured by the Lien of the
Security Agreement to the same extent as though originally issued under this
Agreement.

                  15.5 Cancellation of Notes. All Notes surrendered to Borrower
for payment, prepayment in full, transfer or exchange shall be canceled by it,
and no Note shall be issued in lieu thereof except as expressly permitted by the
provisions of this Agreement.

SECTION 16. MISCELLANEOUS PROVISIONS

                  16.1 Modifications, Consents and Waivers; Entire Agreement.
(a) No modification, amendment or waiver of any provision of the Financing
Documents, any other agreement, instrument and document delivered pursuant to
the Financing Documents or consent to any departure by Borrower from any of the
terms or conditions of the Financing Documents shall be effective unless it is
in writing and signed by the parties to such Financing Document or other
agreement, instrument or document or, in the case of this Agreement, by Agent
and by the requisite the Lenders as set forth in Section 16.1(b). Any such
waiver or consent shall be effective only in the specific instance and for the
purpose for which given. No consent to or demand on Borrower in any case shall,
of itself, entitle it to any other or further notice or demand in similar or
other circumstances.

                  (b) The provisions of this Agreement may be modified, amended
or waived, or a consent given with respect to such provisions, if signed by
Agent and the Majority Lenders, except that:

                  (i) any modification, amendment, waiver or consent that has
         the effect of changing or waiving the Commitment of any Lender, the
         principal amount of the Advances to be borrowed or repaid, the maturity
         of the Loan, the dates for and the amount of repayment of any Advance,
         the Interest Rate and the provisions of this Section 16.1(b) shall
         require the agreement of Agent and all the Lenders; and

                  (ii) any modification or amendment that has the effect of
         increasing the Total Commitment (but not the Commitment of any Lender)
         shall require the agreement of Agent and Majority Lenders.

                  (c) Every notice or demand shall, except so far as otherwise
expressly provided by this Agreement, be deemed to have been received if sent by
internationally recognized overnight courier service or registered mail, upon
acknowledgment of receipt or as of the date on which receipt of such notice
delivered by overnight courier or registered mail is refused or such courier or
the relevant postal service advises that such letter is not deliverable at the
address set out in Section 16.2 or, in the case of a telefax, after the sender
has received evidence of successful transmission.

                  (d) Any party hereto may change its address for the purpose of
giving notice by advising the other parties of such change of address in a
notice given pursuant to the provisions of this Section 16.2.

                  16.3 Entire Agreement; No Oral Change. This Agreement
(including all Exhibits and Appendices hereto and documents or instruments
executed in connection herewith) embodies the entire agreement and understanding
between Borrower, Agent and the Lenders relating to the subject matter hereof
and thereof and supersedes all prior agreements and understandings relating
hereto and thereto and none of the parties hereto or thereto shall be bound by
or charged with any oral or written agreements, representations, warranties,
statements, promises or understandings not specifically set forth herein or
therein. This Agreement may not be changed and no right granted or obligation
imposed hereunder may be waived orally, but only by an instrument in writing
signed by the party against whom enforcement of any waiver, change, modification
or discharge is sought.

                  16.4 Governing Law; Jurisdiction and Venue. THIS AGREEMENT
SHALL BE DEEMED TO HAVE BEEN NEGOTIATED AND MADE IN, AND SHALL BE GOVERNED AND
INTERPRETED UNDER THE LAWS OF, THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS
MADE BY RESIDENTS THEREOF TO BE WHOLLY PERFORMED THEREIN. Borrower, Agent and
the Lenders hereby consent and submit to the non-exclusive jurisdiction and
venue of the United States District Court of the Southern District of New York
and agree that venue is proper in those courts and waive any right to object
based upon jurisdiction (either personal or subject matter) or venue or
inconvenient forum therein in connection with any action arising out of, or
connected in any way with, this Agreement, the Notes or any other Financing
Document executed in connection herewith or therewith or contemplated hereby or
thereby. Borrower agrees that service of process or any other papers upon it by
registered air mail at its address set forth herein shall be deemed good, proper
and effective service upon it. Nothing set forth herein shall be deemed to
preclude the service of process or any other papers upon Borrower by any other
method permitted by Applicable Law.

                  16.5 Usury. Notwithstanding any provision to the contrary
herein contained neither Agent nor the Lenders shall collect a rate of interest
on any obligation owing by Borrower to the Lenders in excess of the maximum rate
of interest permitted by Applicable Law. Borrower understands and believes that
the lending transaction which is the subject of this Agreement complies with all
applicable usury laws; however, if any interest or other charges in connection
with such lending transaction are ever determined to


                                      -51-

<PAGE>   58

exceed the maximum amount permitted by law, then Borrower agrees that (a) the
amount of interest or charges payable pursuant to this Agreement and the Notes
shall be reduced to the maximum amount permitted by law, and (b) any excess
amount previously collected from Borrower in connection with this Agreement or
Notes that exceeds the maximum amount permitted by law shall be credited against
the principal amount of the Loan then outstanding. If the outstanding principal
balance of the Loan has been paid in full, the excess amount paid shall be
refunded to Borrower. The "contracted for rate of interest" of the Commitment to
be advanced pursuant to the terms hereof includes the following: (i) the
Interest Rate calculated and applied to the principal balance of the Loan in
accordance with the provisions of this Agreement and the Notes; (ii) the rate of
interest to be calculated and applied with respect to the principal balance of
the Loan outstanding in accordance with the provisions of Section 4.2(c); (iii)
the fees set forth in Section 12; and (iv) all fees, charges, goods, things in
action or any sum or things of value (collectively, "Additional Sums") paid or
payable by Borrower, whether pursuant to this Agreement or any other Financing
Document. If any such Additional Sums may, under Applicable Law, be deemed to be
interest with respect to the lending transaction which is the subject of this
Agreement, then, for the purpose of any Applicable Law that may limit the
maximum amount of interest to be charged with respect to the lending transaction
which is the subject of this Agreement, such Additional Sums shall be payable by
Borrower as, and shall be deemed to be, additional interest, and for such
purposes only, the agreed upon and "contracted for rate of interest" of this
transaction shall be deemed to be increased by the rate of interest resulting
from the Additional Sums.

                  16.6 No Broker. Each of Borrower, Agent and the Lenders hereby
represent and warrant to the other that no broker brought about the transactions
contemplated hereby and each party hereby agrees to indemnify and hold the other
party harmless from, any and all liabilities and costs (including without
limitation, costs of counsel) to any person or entity claiming brokerage
commissions or finder's fees on account of this Agreement.

                  16.7 Survival. Each of the representations, warranties and
covenants of Borrower contained herein shall survive the Closing Date.

                  16.8 Waiver of Jury. Borrower, Agent and the Lenders
irrevocably waive the right to a trial by jury in any action or proceeding
brought to enforce any provision of this Loan Agreement, the Notes, the Security
Agreement or any other Financing Document to which they are parties.

                  16.9 Assignment, Successors and Assigns. (a) Borrower shall
not assign any rights under this Agreement nor shall any of Borrower's duties
hereunder or under the Notes, Security Agreement or other Financing Documents to
which it is a party be assigned or delegated without the prior written consent
of the Majority Lenders which consent shall not be unreasonably withheld or
delayed, and any such assignment or delegation shall be null and void.


                                      -52-

<PAGE>   59

                  (b) Each of the Lenders or any assignee, transferee or
sub-participant (a "Transferee") may with the prior consent of Borrower, such
consent not to be unreasonably withheld or delayed, assign all or any part of
its rights and benefits under this Agreement, and each of the Lenders or any
Transferee may without the prior consent of Borrower at any time sub-participate
all or any part of its rights and benefits under this Agreement; provided, that
no such assignment or sub-participation made as aforesaid will result in the
obligations of Borrower under this Agreement being greater than they would have
been in the absence of such assignment.

                  (c) A Lender may disclose to a potential Transferee such
information about Borrower as shall have been made available to that Lender in
connection with this Agreement generally and additionally may disclose such
information to any affiliate of that Lender or, on being requested to provide
the same, to any governmental or regulatory body.

                  (d) The Lender or any Transferee may at any time and from time
to time change its lending office but such Lender shall give Borrower prior
notice thereof. Until Borrower receives such notification, it shall be entitled
to assume that the Lender or Transferee is acting through the lending office of
which it last had notice; provided that no such change of lending office (unless
made at the request of Borrower) will result in Borrower's obligations hereunder
being greater than they would have been in the absence of such change.

                  16.10 Captions and Section Headings; Construction. Captions
and Section headings used herein are for convenience only and are not a part of
this Agreement and shall not be used in construing it. This Agreement and all
documents executed in connection with this Agreement shall be construed without
regard to the identity of the party that prepared such document, and no
presumption shall arise as a result thereof.

                  16.11 Severability. In the event that any one or more of the
provisions of this Agreement, the Notes or any Financing Document shall be
invalid, illegal or unenforceable in any respect or in any jurisdiction, the
validity, legality and enforceability of the remaining provisions contained
herein and therein or of the same provisions in any other jurisdiction shall not
in any way be affected or impaired thereby.

                  16.12 Time of the Essence. Time is of the essence with respect
to all of the payment and performance obligations of Borrower under the
Financing Documents.

                  16.13 Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall constitute an original and, when taken
together, all of which shall constitute one and the same Agreement.
