1.       Summary of Significant Accounting Policies

         Basis of Presentation

         AeroCentury IV, Inc. (the "Company") was incorporated in the state of
California on February 7, 1997 ("Inception"). The Company was formed solely for
the purpose of acquiring Income Producing Assets. The Company offered up to
$10,000,000 in $1,000 Secured Promissory Notes maturing on April 30, 2005 (the
"Notes") pursuant to a prospectus dated May 21, 1997 (the "Prospectus").

         All of the Company's outstanding common stock is owned by JetFleet
Holding Corp. ("JHC"), a California corporation formed in January 1994. In May
1998, JetFleet Management Corp., the sole shareholder of the Company was renamed
JetFleet Holding Corp. The rights and obligations under the management agreement
between the Company and JHC were assigned by JHC to a newly-created wholly-owned
subsidiary named "JetFleet Management Corp." ("JMC"). JMC also manages
AeroCentury Corp. ("ACY"), a Delaware corporation, and JetFleet III, a
California corporation, which are affiliates of JHC and which have objectives
similar to the Company's. Neal D. Crispin, the President of the Company, holds
the same position with JHC and JMC and owns a significant amount of the common
stock of JHC.

         Cash and Cash Equivalents/Deposits

         The Company considers highly liquid investments readily convertible
into known amounts of cash, with original maturities of 90 days or less, as cash
equivalents. Deposits represent cash balances held related to maintenance
reserves and security deposits and are subject to withdrawal restrictions. As of
June 30, 2001, the Company maintained $1,475,980 of its cash balances in a money
market fund held by a regional brokerage firm, which is not federally insured.

         Aircraft and Aircraft Engines Under Operating Leases

         The Company's interests in aircraft are recorded at the lower of cost
or market value, which include acquisition costs (see Note 2). Depreciation is
computed using the straight-line method over each aircraft's estimated economic
life to its estimated residual value.

         Impairment of Long-lived Assets

         In accordance with SFAS No. 121, "Accounting for the Impairment of
Long-lived Assets and Long-lived Assets to Be Disposed Of," assets are reviewed
for impairment whenever events or changes in circumstances indicate that the
book value of the asset may not be recoverable. Periodically, the Company
reviews its long-lived assets for impairment based on estimated future
non-discounted cash flows attributable to the assets or appraisals. In the event
such cash flows are not expected to be sufficient to recover the recorded value
of the assets, the assets are written down to their estimated realizable value.

         Debt Issue Costs

         Pursuant to the terms of the Prospectus, the Company paid an
Organization and Offering Expense Reimbursement to JHC in cash in an amount up
to 2.0% of Aggregate Gross Offering Proceeds for reimbursement of certain costs
incurred in connection with the organization of the Company and the Offering
(the "Reimbursement").

1.       Summary of Significant Accounting Policies (continued)

         Debt Issue Costs (continued)

         To the extent that JHC incurred expenses in excess of the 2.0% cash
limit, such excess expenses were repaid to JHC in the form of Common Stock
issued by the Company at a price of $1.00 per share (the "Excess Stock"). The
amount of Excess Stock that the Company can issue was limited according to the
amount of Aggregate Gross Offering Proceeds raised by the Company. The Company
capitalized the Reimbursement paid and amortizes such costs over the life of the
Notes (approximately eight years).

         Assets Subject to Lien

         The Company's obligations under the Notes are secured by a security
interest in all of the Company's right, title and interest in the Income
Producing Assets acquired by the Company.

         Income Taxes

         The Company follows the liability method of accounting for income taxes
as required by the provisions of Statement of Financial Accounting Standards No.
109 - Accounting for Income Taxes.

         Use of Estimates

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts and disclosures. Accordingly,
actual results could differ from those estimates.

         Recent Accounting Pronouncements

         SFAS No. 137, which amended the effective date of SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities, was issued in June
1999. The Company adopted SFAS No. 133 on January 1, 2001. This statement
establishes accounting and reporting standards requiring that all derivative
instruments are recorded on the balance sheet as either an asset or a liability,
measured at fair value. The statement requires that changes in the derivative's
fair value be recognized currently in earnings unless specific hedge accounting
criteria are met and such hedge accounting treatment is elected. Because the
Company does not hold any derivatives as defined in SFAS No. 133, the adoption
of SFAS No. 133 did not have a material impact on its results of operations or
financial position.

          In December 1999, the Securities and Exchange Commission ("SEC")
issued Staff Accounting Bulletin No. 101, Revenue Recognition in Financial
Statements ("SAB 101"). SAB 101, as amended, summarizes certain of the SEC's
views in applying generally accepted accounting principles to revenue
recognition in financial statements. SAB 101 was adopted by the Company in 2000.
The adoption of the provisions of SAB 101 did not have a material effect on the
Company's consolidated operating results, statement of financial position or
cash flow.

2.       Aircraft and Aircraft Engines Under Operating Leases

         Aircraft and Aircraft Engines

         At June 30, 2001, the Company owned a Fairchild Metro III aircraft,
serial number AC-647 ("S/N AC-647"), and a Pratt & Whitney JT8D-9A aircraft
engine, serial number 674452B (the "Engine"). In January 2001, the Company sold
its 50% interest in a Shorts SD3-60-100, serial number S/N 3676 ("S/N 3676").
The Company did not purchase any aircraft during the first six months of 2001.

         Aircraft and Aircraft Engines Leases

         When S/N AC-647 was acquired, it was subject to a 36-month lease,
expiring in April 2001, with a regional carrier in Uruguay. During June 1999,
however, management repossessed the aircraft due to non-payment of rent. In June
2000, S/N AC-647 was re-leased to a U.S. carrier for a two-year term, expiring
in June 2002.

         The Engine is used on a McDonnell Douglas DC-9 aircraft and is subject
to a 60-month lease with the seller, expiring in November 2002. The Engine is
subleased by the seller to a Mexican-based regional carrier.

         At the time of purchase, S/N 3676 (owned 50% by the Company) was
subject to a 48-month lease, expiring in July 2001, with a British regional
airline. The original lease, entered into in 1997, did not require that the
lessee pay maintenance reserves based on usage because, at the time, the lessee
was considered creditworthy. It had recently been named Airline of the Year by
the European Regions Airline Association and had its own facility, which was
certified to perform any required maintenance. Subsequently, the airline
experienced financial difficulties and, on February 24, 2000, filed for
reorganization.

         The lessee continued to operate, and, under the reorganization plan,
the lessee paid rentals on a month to month basis at the same rent as under the
original lease on S/N 3676. Under the plan, the lessee also began paying monthly
maintenance reserves based on the hours flown. Under British law, the owners
were precluded from repossessing the aircraft so long as the lessee was
operating it and agreed to pay rent and maintenance reserves under its
reorganization plan. The lessee notified the owners that the aircraft would be
returned to them during the fourth quarter of 2000. The owners agreed that they
would realize a greater benefit if they sold the aircraft "as is" rather than
fund the maintenance work necessary to return the aircraft to a condition which
would allow it to possibly be re-leased to a new lessee. Therefore, the Company
reduced the carrying value of the aircraft to $170,000 and recognized a
provision for impairment estimated to be $245,350 during 2000. The aircraft was
returned to the Company and, in January 2001 it was sold. The Company received
net proceeds of $167,450 and recognized a gain of $35,980. During the second
quarter of 2001, the lessee paid all amounts owed to the Company and, since the
aircraft had been sold, the Company recognized an additional gain of $77,020,
representing maintenance reserves retained. The lessee also paid two months of
rent, which the Company had accrued during 2000, for a second plane it had
leased and which was sold during 2000.

         As of June 30, 2001, minimum future lease rent payments receivable
under noncancelable leases were as follows:
                  Year                   Amount

                  2001              $     150,000
                  2002                    192,500
                                    -------------

                                    $     342,500

3.       Medium-Term Secured Notes

         As mentioned above, the Company raised funds through the Offering from
May 1997 to August 1997. During 1997, the Company accepted subscriptions for
4,869 Notes aggregating $4,869,000 in Gross Offering Proceeds. Pursuant to the
Prospectus, the Company subsequently issued $4,869,000 in Notes due April 30,
2005. The Notes bear interest at an annual rate of 10.00%, which is due and
payable on a quarterly basis, in arrears, on the first business day of February,
May, August and November. As described in Note 6 to the financial statements,
there is substantial doubt as to the Company's ability to continue as a going
concern. Therefore, the fair value of the Notes is estimated to be approximately
$2,526,000, which is $2,343,000 less than the carrying value. The fair value of
the notes payable is estimated based upon the net book values of the aircraft
and the current net working capital of the Company.

</TABLE>

         The Company does not anticipate generating adequate future taxable
income to realize the benefits of the remaining deferred tax assets on the
balance sheet. Therefore, the Company has recognized a valuation allowance equal
to the net deferred tax asset.

         As discussed in Note 1, the Company is a subsidiary of JHC. JHC files a
consolidated tax return that includes the Company as a member of the
consolidated group. The current and deferred taxes of the consolidated group are
allocated to members of the group in their separately issued financial
statements. Current and deferred income taxes are allocated to members of the
group by applying FAS 109 as if it were a separate taxpayer. In addition, the
members of the group record inter-company receivables and payables to reflect
the tax benefits of net operating losses used in the consolidated tax return.
However, under the terms of the tax sharing arrangement with other members of
the consolidated group, the Company does not expect its inter-company receivable
to be collected because it does not expect to generate adequate future taxable
income. The Company's current net operating losses may be carried forward for
twenty years and begin to expire in 2020.

5.       Related Party Transactions

         The Company's Income Producing Asset portfolio is managed and
administered under the terms of a management agreement with JMC. Under this
agreement, on the last day of each calendar quarter, JMC receives a quarterly
management fee equal to 0.5% of the Company's Aggregate Gross Proceeds received
through the last day of such quarter. In the first six months of 2001 and 2000,
the Company accrued a total of $48,690 and $48,690, respectively, in management
fees to JMC.

         JMC may receive an acquisition fee for locating assets for the Company
and a remarketing fee in connection with the sale of the Company's assets,
provided that such fees are not more than the customary and usual fees that
would be paid to an unaffiliated party for such a transaction. The total of the
Aggregate Purchase Price plus the acquisition fee cannot exceed the fair market
value of the asset based on appraisal. JMC may also receive reimbursement of
Chargeable Acquisition Expenses incurred in connection with a transaction which
are payable to third parties. During the first six months of 2001 and 2000, no
acquisition fees or reimbursements for Chargeable Acquisition Expenses were paid
as the Company did not acquire additional assets. During the first six months of
2001, remarketing fees of $2,550 were paid to JMC in connection with the sale of
aircraft. No remarketing fees were paid during the first six months of 2000.

                          Notes to Financial Statements

5.       Related Party Transactions (continued)

         As discussed in Note 1, the Company reimbursed JHC for certain costs
incurred in connection with the organization of the Company and the Offering.
The Company made no such payments during 2001 and 2000.

6.       Going Concern

         As shown in the accompanying financial statements, as of June 30, 2001,
the Company's total liabilities exceeded its total assets by $2,035,410. In
addition, although the Company has recently sold several aircraft, it does not
believe that it has sufficient total proceeds to invest in another income
producing asset and, therefore, as provided under the Trust Indenture, it
anticipates turning over those proceeds to the Trustee. The Company's cash flow
projections show that it will not have sufficient cash balances to fund the
required interest payment of approximately $122,000 on November 1, 2001. The
Company has informed the Trustee that it will be unable to make such payment and
that it will, therefore, be in default under the Trust Indenture at that time.
Under the Trust Indenture, the Trustee would then have the right to manage the
Company's assets, all of which are collateral for the notes obligation.
Management of the Company's assets and extinguishment of its liabilities would
then become the responsibility of the Trustee.

         These factors create a substantial uncertainty about the Company's
ability to continue as a going concern. The financial statements do not include
any adjustments that might be necessary if the Company is unable to continue as
a going concern.

Item 2.         Management's Discussion and Analysis or Plan of Operation.

Forward-Looking Statements

Certain  statements  contained in this report and, in particular,  the
discussion  regarding:   the  Company's  beliefs,  plans,  objectives,
expectations  and  intentions  regarding  its  inability  to  pay  the November
1, 2001 interest payment,  the realization of benefits of its deferred tax
assets,  collection of intercompany tax receivables under its tax sharing
agreement,  the  incurring of  significant  operating expenses for assets on
lease, the insufficiency of sales proceeds from asset sales to invest in
additional assets, anticipated disposition of the assets by the Trustee, and the
Trustee's  actions after a November 2001  default  to  take  control  of the
Company's  assets,  and  the inadequacy of cash reserves to meet short-term
immediate requirements; are forward looking  statements.  While the company
believes that such statements  are  accurate,  actual  results  may differ due
to further defaults   by   existing   lessees,   general   economic  conditions,
particularly  those that affect the re-sale value of turboprop aircraft and
engines,  including  competition for turboprop and other aircraft, and future
trends and results that cannot be predicted with certainty.  The  Company's
actual  results  could  differ  materially  from those discussed in such forward
looking statements. Factors that could cause or contribute to such differences
include those discussed below in the section  entitled  "Factors  that  May
Affect  Future  Results."  The cautionary statements made in this Report should
be read as being applicable to all related forward-looking statements  wherever
they appear in this Report.

Results of Operations

The Company recorded a net loss of ($94,460) and ($222,060) or ($0.39) and
($0.91) per share for the six months ended June 30, 2001 and 2000, respectively,
and ($24,110) and ($160,970) or ($0.10) and ($0.66) per share for the three
months ended June 30, 2001 and 2000, respectively.

Rental income decreased by approximately $171,000 and $60,000 in the six months
and three months, respectively, of 2001 due to the sale of aircraft during the
fourth quarter of 2000 and first quarter of 2001. Gain on sale of aircraft was
approximately $113,000 and $77,000 in the same periods of 2001 due to the sale
of S/N 3676 during January and the recording of additional gain during the
second quarter associated with reserves retained. There were no asset
dispositions during the first half of 2000. Interest income was higher in 2001
by approximately $24,000 and $11,000 in the six month and three periods,
respectively, due to higher cash balances in 2001 as a result of asset sales.
Depreciation decreased approximately $71,000 and $36,000 in the same periods due
to the asset sales noted above. Maintenance expense was approximately $50,000
and $7,000 lower in the six months and three months, respectively, ended June
30, 2001 than in 2000 as a result of maintenance work performed on an aircraft
upon its return during 2000.

Under the terms of a tax sharing arrangement between the members of the
consolidated group with which the Company files a consolidated tax return, in
the event that the Company has taxable income, the Company will be credited for
the tax benefits provided by the use of the Company's prior year net operating
losses. However, under the terms of the tax sharing agreement with other members
of the consolidated group, the Company does not expect its inter-company
receivable to be collected because it does not expect to generate adequate
future taxable income.

Capital Resources and Liquidity

The Company's current financial condition is a result of several factors,
primarily the default on lease obligations by the original lessees of four of
the Company's five aircraft. As a result of such defaults, the aircraft were
repossessed by the Company or returned early by the lessees, which meant that
the Company had to sell the aircraft earlier than anticipated or negotiate lease
terms with new lessees. See "Factors that May Affect Future Results," below, for
a complete discussion of factors affecting the Company's cash flow.

At June 30, 2001, the Company had cash balances of $1,400,180 and deposits of
$78,680. Approximately $122,000 of the Company's cash balances was held for the
interest payment made to the Noteholders in August 2001. The remaining cash,
which was the result of aircraft sales during the fourth quarter 2000 and first
quarter of 2001, is being held for transmittal to the Trustee as required under
the terms of the Trust Indenture.

Since its formation, the Company's capital has come in the form of equity
contributions from JHC, proceeds from the Offering, rental revenue from the
Income Producing Assets purchased using those proceeds, and, most recently,
proceeds from the sale of assets. The Company's liquidity varies, increasing to
the extent cash flows from operations exceed expenses, and decreasing as
interest payments are made to the Noteholders and to the extent expenses exceed
cash flows from leases.

Since the Company has acquired Income Producing Assets, which are subject to
triple net leases (the lessee pays operating and maintenance expenses, insurance
and taxes), the Company does not anticipate that it will incur significant
operating expenses in connection with ownership of its Income Producing Assets
as long as they remain on lease.

Excess cash flow from operations, after interest payments on the Notes, has been
held as cash because it was, in the aggregate, insufficient to purchase
additional Income Producing Assets. In addition, although the Company has
recently sold several aircraft that were returned after lessee defaults, it does
not believe that the total proceeds of such sales are sufficient to invest in a
desirable Income Producing Asset and, therefore, as required by the Trust
Indenture, the Company anticipates turning over those sales proceeds to the
Trustee. After May 1, 2003, any excess cash, after interest payments on the
Notes, is required to be deposited to a sinking fund account established to
facilitate repayment of principal of the Notes on their maturity.

During the second quarter of 2001, the Company received payment of the past due
rent and reserves from the previous lessee of S/N 3606 and S/N 3676. The receipt
of such funds enabled the Company to make the required interest payment of
approximately $122,000 on August 1, 2001. However, the Company's cash flow
projections show that it will not have sufficient cash balances to fund the
required interest payment of approximately $122,000 on November 1, 2001.

The Company's increase in cash flow from operations was due primarily to a
smaller net loss, excluding the gain on sale of aircraft, during 2001 versus
2000 and the effect of the change in accounts receivable, rent receivable and
accounts payable, which effects were only partially offset by a change in
maintenance deposits from year to year.

The increase in cash flow provided by investing activities was the result of the
Company's sale of an aircraft in January 2001. There was no cash flow from
financing activities in 2001 or 2000 because the Offering terminated in August
1997.

Outlook

The Company currently has Notes outstanding with an aggregate principal face
value of $4,869,000. As discussed in Note 3, the fair value of the Notes, based
upon the net book values of the aircraft and the current net working capital of
the Company, is estimated to be approximately $2,526,000, which is approximately
50% of the face value of the Notes. Through August 1, 2001, the Company has paid
to Noteholders an aggregate of approximately $1,947,800 in interest on the
Notes, or approximately 40% of the face value of the Notes.

Upon the Company's anticipated default in its interest payment on November 1,
2001, the Trustee will likely immediately foreclose on the Company's assets and
assume responsibility for their administration. The Company's two assets are
each currently on lease until June 2002 and November 2002, at a monthly lease
rate of $10,000 and $15,000, respectively.

Upon foreclosure, the Trustee would have discretion as to the disposition of
each asset. It could choose to sell an asset to a third party and immediately
distribute the proceeds of such sale to the Noteholders. In order to achieve an
immediate liquidation of the asset, however, the Trustee may have to accept a
price that is substantially less than the net book value of the asset.
Alternatively, the Trustee may decide to continue to hold an asset for the
benefit of Noteholders and collect rent for such asset until the underlying user
lease expires, or until the Trustee determines that the asset can be sold at an
acceptable price. While the Trustee holds such assets, rental income received by
the Trustee would be held and distributed to Noteholders by the Trustee. If the
Trustee were to retain both assets until lease end, from November 2001 until the
assets' lease expirations, a total of approximately $240,000 could be collected
under the leases; however, the amount of rental income received would
nonetheless be insufficient to permit the Trustee to make net cash distributions
to Noteholders at a rate of 10% per annum on unpaid Note principal (the stated
interest rate under the Notes). In either case, any distributions to Noteholders
of sales and/or rent proceeds would be net of legal and administrative expenses
incurred by the Trustee.

Factors that May Affect Future Results

Anticipated Default; Trustee's Ability to Maximize Returns. As discussed above,
due to cash flow problems created by lessee rental defaults, early termination
of leases, and lower than expected remarketing proceeds described above, it is
anticipated that the Company will be in default under its Indenture upon its
failure to make the November 1, 2001 interest payment. At that time, it is
believed that the Trustee, Wells Fargo Bank Northwest (formerly known as First
Security Bank, N.A.), will take control of the Company's assets securing the
Indenture, namely the aircraft portfolio and leases and approximately $1,260,000
in cash. At that point, the Trustee will have the power to direct disposition of
the collateral with the goal of maximizing value to the Noteholders. This could
entail an immediate or staged disposition of all the assets or retention of the
assets on lease for the benefit of the Noteholders, or a combination thereof.
While the Trustee is unlikely to realize sufficient proceeds to enable repayment
of the entire Note Indebtedness, its ability to maximize repayment to
Noteholders will depend on the risk factors described below, particularly those
that affect asset values of the Company's portfolio.

General Economic Conditions. The market for used aircraft has been cyclical, and
usually reflects economic conditions and the strength of the travel and
transportation industry. At any time, the market for used aircraft may be
adversely affected by such factors as airline financial difficulties, higher
fuel costs, and improved availability and economics of new replacement aircraft.

An adverse change in the global air travel industry, however, could result in
reduced carrier revenue and excess capacity and increase the risk of failure of
some weaker regional air carriers and create lessee credit risks or greater
leasing risks as discussed below.  In particular, a downturn that affects used
aircraft values in the near future may substantially impact the value of the
Company's aircraft portfolio at a time when that portfolio is being liquidated
to repay the Notes.

Leasing Risks. The Company's successful negotiation of lease extensions,
re-leases and sales may be critical to its ability to achieve its financial
objectives, and will involve a number of substantial risks. Demand for lease or
purchase of the assets depends on the economic condition of the airline
industry, which is in turn highly sensitive to general economic conditions.
Ability to remarket equipment at acceptable rates may depend on the demand and
market values at the time of remarketing. The market for used aircraft is
cyclical, and generally, but not always, reflects economic conditions and the
strength of the travel and transportation industry. The demand for and value of
many types of older aircraft in the recent past has been depressed by such
factors as airline financial difficulties, increased fuel costs, the number of
new aircraft on order and the number of older aircraft coming off lease. The
Company's concentration in a limited number of airframe and aircraft engine
types (generally, turboprop equipment) subjects the Company to economic risks if
those airframe or engine types should decline in value. The recent introduction
of "regional jets" to serve on short routes previously thought to be economical
only for turboprop aircraft operation could decrease the demand for turboprop
aircraft, while at the same increasing the supply of used turboprop aircraft.
This could result in lower lease rates and values for the Company's turboprop
aircraft.

Risks Related to Regional Air Carriers. Because the Company's leases are with
regional air carriers, it will be subject to certain risks. First, lessees in
the regional air carrier market include a number of companies that are start-up,
low capital, and low margin operations. Often, the success of such carriers is
dependent upon arrangements with major trunk carriers, which may be subject to
termination or cancellation by such major carrier. This market segment is also
characterized by low entry costs, and thus, there is strong competition in this
industry segment from start-ups as well as major airlines. Thus, leasing
transactions with these types of lessees results in a generally higher lease
rate on aircraft, but may entail higher risk of default or lessee bankruptcy.

Ownership Risks. The Company's portfolio is leased under operating leases, where
the terms of the leases do not take up the entire useful life of an asset. The
Company's ability to recover its purchase investment in an asset subject to an
operating lease is dependent upon the Company's ability to profitably re-lease
or sell the asset after the expiration of the initial lease term. Some of the
factors that have an impact on the Company's ability to re-lease or sell include
worldwide economic conditions, general aircraft market conditions, regulatory
changes that may make an asset's use more expensive or preclude use unless the
asset is modified, changes in the supply or cost of aircraft equipment and
technological developments which cause the asset to become obsolete. In
addition, a successful investment in an asset subject to an operating lease
depends in part upon having the asset returned by the lessee in serviceable
condition as required under the lease. If the Company is unable to remarket its
aircraft equipment on favorable terms when the operating lease for such
equipment expires, the Company's business, financial condition, cash flow,
ability to service debt and results of operation could be adversely affected.

Lessee Credit Risk. If a lessee defaults upon its obligations under a lease, the
Company may be limited in its ability to enforce remedies. The Company's lessees
are small domestic and foreign regional passenger airlines, which may be even
more sensitive to airline industry market conditions than the major airlines. As
a result, the Company's inability to collect rent under a significant lease or
to repossess equipment in the event of a default by a lessee could have a
material adverse effect on the Company's revenue. If a lessee that is a
certified U.S. airline is in default under the lease and seeks protection under
Chapter 11 of the United States Bankruptcy Code, under Section 1110 of the
Bankruptcy Code, the Company would be automatically prevented from exercising
any remedies for a period of 60 days. By the end of the 60 day period, the
lessee must agree to perform the obligations and cure any defaults, or the
Company would have the right to repossess the equipment. This procedure under
the Bankruptcy Code has been subject to significant recent litigation, however,
and it is possible that the Company's enforcement rights may still be further
adversely affected by a declaration of bankruptcy by a defaulting lessee.

International Risks. The Company's portfolio currently includes a lease with a
foreign air carrier. Leases with foreign lessees may present somewhat different
credit risks than those with domestic lessees.

Foreign laws, regulations and judicial procedures may be more or less protective
of lessor rights as those which apply in the United States. The Company could
experience collection problems related to the enforcement of its lease
agreements under foreign local laws and the remedies in foreign jurisdictions.
The protections potentially offered by Section 1110 of the Bankruptcy Code would
not apply to non-U.S. carriers, and applicable local law may not offer similar
protections. Certain countries do not have a central registration or recording
system with which to locally establish the Company's interest in equipment and
related leases. This could add difficulty in recovering an aircraft in the event
that a foreign lessee defaults.

Leases with foreign lessees are subject to risks related to the economy of the
country or region in which such lessee is located even if the U.S. economy
remains strong. On the other hand, a foreign economy may remain strong even
though the domestic U.S. economy does not. A foreign economic downturn may occur
and impact a foreign lessee's ability to make lease payments, even though the
U.S. and other economies remain stable. Furthermore, foreign lessees are subject
to risks related currency conversion fluctuations. Although the Company's
current leases are all payable in U.S. dollars, in the future, the Company may
agree to leases that permit payment in foreign currency, which would subject
such lease revenue to monetary risk due to currency fluctuations. Even with
dollar-denominated lease payment provisions, the Company could still be affected
by a devaluation of the lessee's local currency which would make it more
difficult for a lessee to meet its dollar-denominated lease payments, increasing
the risk of default of that lessee, particularly if that carrier's revenue is
primarily derived in the local currency.

Competition. The Company has many competitors in the aircraft leasing industry,
including leasing companies, banks and other financial institutions and aircraft
leasing partnerships. The market is highly competitive. Most of the Company's
competitors have substantially greater financial and other resources than the
Company.

Casualties, Insurance Coverage. The Company, as owner of transportation
equipment, could be held liable for injuries or damage to property caused by its
assets. Though some protection may be provided by the United States Aviation Act
with respect to its aircraft assets, it is not clear to what extent such
statutory protection would be available to the Company and such act may not
apply to aircraft operated in foreign countries. Though the Company may carry
insurance or require a lessee to insure against a risk, some risks of loss may
not be insurable. An uninsured loss with respect to the Equipment or an insured
loss, for which insurance proceeds are inadequate, would result in a possible
loss of invested capital in and any profits anticipated from such equipment.

Reliance on JMC. All management of the Company is performed by JMC pursuant to a
management agreement between JMC and the Company. The Board of Directors does,
however, have ultimate control and supervisory responsibility over all aspects
of the Company and does owe fiduciary duties to the Company and its
stockholders. In addition, while JMC may not owe any fiduciary duties to the
Company by virtue of the management agreement, the officers of the Company are
also officers or employees of JMC, and in that capacity owe fiduciary duties to
the Company and the stockholders by virtue of holding such offices. Although the
Company has taken steps to prevent such conflicts, such conflicts of interest
arising from such dual roles may still occur.
