                         NOTES TO FINANCIAL STATEMENTS
                                        

1.  Basis of Presentation

The accompanying unaudited financial statements have been prepared by Tower Air,
Inc. (the "Company") in accordance with generally accepted accounting principles
for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X.  Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, these financial
statements contain all adjustments, consisting of normal recurring accruals,
necessary to present fairly the financial position, results of operations and
cash flows for the periods indicated.  These interim financial statements and
related notes should be read in conjunction with the financial statements and
notes included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1998.  The results of operations for the three months ended March
31, 1999 are not necessarily indicative of the results that may be expected for
the full year.


2.  Long-Term Debt

In September 1997, the Company entered into a Loan Agreement which extended the
term of a line of credit with Heller Financial, Inc. (Heller) until September
1999. The line of credit, which was increased from $15.0 million to $20.0
million on April 14, 1999, decreasing to $15.0 million on August 31, 1999 and
thereafter, is further limited to suppressed availability based on the value of
the collateral. As of April 14, 1999, the Company has $19.3 million of
availability based on the value of the collateral at such time. The line of
credit is secured by accounts receivable, general intangibles, inventory,
intellectual property, cash held in the Company's lock-box account, one spare
airframe, aircraft spare parts and landing and gate rights. The Loan Agreement
provides that the Company shall not, directly or indirectly, create or become
liable in respect of any indebtedness, with certain specified exceptions.

Since February 1998, the Company has entered into nine amendments to the Loan
Agreement providing, among other things, for (i) changes in the maximum amount
of the revolving loan during different periods; (ii) subordination of loans made
to the Company by officers and directors; (iii) increases to the spread between
the amount of collateral required and the amount of available borrowing under
the Loan Agreement; (iv) modification of the financial covenant relating to the
Company's Tangible Net Worth (as defined therein) to facilitate compliance by
the Company; and (v) increases in the interest rate from Prime (as defined
therein) plus 0.75% to Prime plus 1.50% (9.25% at December 31, 1998).  Through a
combination of the fourth amendment on May 14, 1998 and the sixth amendment on
July 13, 1998, the Company and Heller agreed to modify the Tangible Net Worth
covenant in the Loan Agreement by reducing the amount of Tangible Net Worth the
Company is required to maintain from $47.0 million prior to August 31, 1998 and
$55.0 million thereafter to $35.0 million through May

                                       6

1998, $38.0 million for June 1998, $47.5 million through August 1, 1998 and
$55.0 million from August 31, 1998 and thereafter. On June 1, 1998, the fifth
amendment permanently limited the maximum amount of borrowings under the
facility to $15.0 million beginning on June 29, 1998, a decrease from the $25.0
million maximum amount originally permitted. The sixth amendment to the Loan
Agreement waived defaults resulting from the repayment of the 12% Note (as
defined herein), the issuance of the Nachtomi Note (as defined herein) and the
defaults referred to below. On August 27, 1998, the seventh amendment to the
Loan Agreement between the Company and Heller modified again the Tangible Net
Worth covenant in the Loan Agreement by reducing the amounts of Tangible Net
Worth the Company is required to maintain to $44.5 million in July 1998, $45.0
million from August 1998 through March 1999 and to $50.0 million in April and
May 1999. On April 14, 1999, the eighth amendment to this Loan Agreement
increased the maximum amount of borrowings under the facility to (i) $20.0
million from April 14, 1999 to May 30, 1999, (ii) $19.0 million from May 31,
1999 to June 29, 1999, (iii) $18.0 million from June 30, 1999 to July 30, 1999,
(iv) $16.0 million from July 31, 1999 to August 30, 1999, and (v) $15.0 million
on August 31, 1999 and thereafter. In addition, under the eighth amendment, the
Company agreed to maintain at all times an amount of excess collateral available
under the facility of $7.0 million, plus an additional $0.5 million for each
additional $1.0 million borrowed above $15.0 million. This eighth amendment also
waived a covenant default relating to defaults of certain covenants. On April
15, 1999, the ninth amendment to the loan agreement between the Company and
Heller further modified the Tangible Net Worth covenant in the loan agreement by
reducing the amounts the Company is required to maintain to $45.0 million from
March 1999 through June 1999 and $50.0 million thereafter through September
1999. As of March 31, 1999, the Company had $12.1 million of obligations
outstanding under the Loan Agreement, with an additional $2.0 million consisting
of letters of credit issued to various suppliers and insurance companies.

In January 1998, the Company entered into a $15.0 million loan agreement with a
commercial financial institution secured by twelve Pratt & Whitney engines, of
which $11.3 million was used to pay the balance remaining on two previous
agreements with the same commercial financial institution. On February 8, 1999,
the aggregate balance of $6.8 million outstanding on this note was paid from the
proceeds of a sale and leaseback transaction with another commercial financial
institution. Under this capitalized sales and leaseback arrangement, the Company
is required to make fixed monthly payments of approximately $0.3 million
consisting of principal and interest at 10.6% through January 2004.


                                       7

In February and March 1998, the Company borrowed $6.0 million which bears
interest at a rate of 12% (the "12% Note") from Funding Enterprises, LLC, a
limited liability Company in which the Company's Chairman and former President
were members.  On July 1, 1998, the Company discharged its obligations under the
12% Note by issuing a new note (the "Nachtomi Note"), due August 7, 1998, to the
Company's Chairman in the principal amount of $3.0 million and repaying the
balance of the 12% Note in cash. The Nachtomi Note originally provided for
interest at an annual rate of 12.0%, increasing to 15% after August 7, 1998.
The Nachtomi Note was amended on August 6, 1998, establishing an annual interest
rate of 12% after August 7, 1998, as well as a new maturity date of April 30,
1999.  On April 14, 1999, the Nachtomi Note was amended to extend the maturity
date to January 1, 2000.  In connection with the 12% Note, warrants for the
purchase of 1.2 million shares of Common Stock of the Company were issued with
an exercise price of $5.00.  The warrants expire in February 2008.

From September 1997 through March 1998, the Company entered into a finance
agreement involving the conversion and refurbishment of Pratt & Whitney engines.
In connection with this transaction, eight engines were financed for $38.4
million with interest at prime plus 2%.  In September 1998, the lender agreed to
increase the loan to include $4.2 million relating to certain engines previously
overhauled.  The loan was restructured and now requires a total monthly payment
of $1.5 million through March 1999 and $2.0 million through July 1999 and $2.5
million through August 2000 which allows the Company to repair/overhaul
additional engines currently at the repair facility with interest at 6% going up
to a maximum of 9% per annum. Under this restructuring agreement, the Company
was unable to make required payments for January through March 1999 amounting to
$4.5 million.  The Company has reached an understanding with the financial
institution whereby this amount will be paid by September 1999.

In July 1998, the Company did not meet the minimum net worth requirements of an
operating lease agreement entered into in connection with a sale and leaseback
transaction, but has obtained a waiver of that provision through July 31, 1999.
In addition, on April 14, 1999, the Company obtained waivers under certain lease
and debt agreements for a covenant default relating to defaults of certain
covenants. The Company obtained agreements with other lessors for deferred or
revised payment terms for approximately $8.1 million of lease and maintenance
reserve payments. As of March 31, 1999, the outstanding amount is approximately
$2.3 million. In addition, the Company agreed with certain of its vendors and
suppliers to extend payment terms, and has, in some cases, obtained payment
extensions with respect to certain of the Company's current obligations.

On July 15, 1998, the Company purchased an existing leased aircraft from a
lessor for a purchase price of $13.5 million of which a credit of $6.0 million
was given by the lessor to the Company for the payment of maintenance reserves
paid during the lease period and a balance of $7.5 million was financed by the
same lessor.  In addition, the lessor waived all previously outstanding rent and
maintenance reserves through June 30, 1998 amounting to $1.4 million.  This loan
requires a monthly payment of approximately $50,000 of interest only starting
October 1998 through May 1999 and then a total monthly payment of approximately
$0.4 million including principal and interest through March 2001.

On August 13, 1998, the Company restructured three existing loans with a
financial institution under which the Company was required to pay a total
monthly principal payment of $1.5 million.  Under the terms of these
restructured Aircraft Loan and Security Agreements, the Company is required to
pay an aggregate monthly principal payment of $0.5 million plus interest through
March 1999, which will pay off one of the three loans and the remaining two
loans will require a monthly principal and interest payment, commencing April
1999, of $1.2 million and $0.5 million through December 2002 and February 2003,
respectively.

On November 13, 1998, the Company purchased another existing leased aircraft
from a lessor for a purchase price of $21.0 million of which $20.0 million was
financed by the same lessor.  The loan is comprised of two notes of $10.0
million each and requires a fixed total monthly payment of $105,000 each
consisting of principal and interest.

On December 31, 1998, the Company purchased three Pratt and Whitney engines from
a vendor for a total purchase price of $8.1 million of which $6.7 million was
financed by the same vendor. The loan, which bears interest at 9.0% per annum,
is for three years and requires a fixed monthly payment of $.2 million
consisting of principal and interest starting February 1, 1999.

On March 2, 1999, the Company purchased an existing leased aircraft for $24.5
million under a capitalized lease arrangement from the existing lessor.  The
Company is required to make fixed monthly payments of approximately $0.4 million
consisting of principal and interest at 9.7% through September 2006.

On March 24, 1999, the Company purchased four Pratt & Whitney engines from a
commercial financial institution for a total purchase price of $10.8 million of
which $9.1 million was financed by the same financial institution.  The loan,
which bears interest at 10.0% per annum, is for a period of eighteen months and
requires a fixed monthly payment of $0.5 million consisting of principal and
interest starting April 23, 1999.

The Company has entered into a letter of intent with International Lease Finance
Corp. to lease two new Boeing 777 aircraft for an initial term of ten years.  If
a definitive agreement is executed, the Company will be required to pay $4.8
million in deposits for the two leased aircraft, of which $0.4 million is due
during the first half of 1999.  The deposits are refundable, subject to certain
conditions, at the end of the lease term.

As of March 31, 1999, the Company had $70.4 million of required principal
payments on long-term debt due within one year.


3.  Stockholders' Equity

In an effort to conserve cash, the Company suspended cash dividends on its
Common Stock after the third quarter of 1996.


4.  Income Taxes

Income taxes are calculated at the estimated annual effective tax rate, which
differs from the federal statutory rate of 35.0%, primarily due to the effect of
state income taxes and certain nondeductible items.


5.  Earnings Per Share

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, Earnings Per Share, Statement No. 128
replaced the calculation of primary earnings per share and fully diluted
earnings per share with basic and diluted earnings per share.  Unlike primary
earnings per share, basic earnings per share excluded any dilutive effects of
options, warrants, and convertible securities.  Diluted earnings per share is
very similar to the previously reported fully diluted earnings per share.  All
earnings per share amounts have been

requirements.

The following table sets forth the computation of basic and diluted earnings per
share:

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations.


Special Note Regarding Forward-looking Statements:

Certain statements contained herein constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1996.
Such statements incorporate assumptions that entail uncertainties and unknown
risks.  A variety of factors may cause the actual results and performance of the
Company or industry to differ materially from any future results or performance
expressed or implied by such forward-looking statements.  These factors include,
among others, the following: general economic conditions affecting the industry
and the Company; competition within the industry; changes in consumer
preferences; regulatory changes; and political, social and economic conditions
in key markets.


Results of Operations

For the three-month period ended March 31, 1999 (the "1999 First Quarter"), the
Company recorded an operating profit of $0.5 million and a net loss of $2.0
million, or $0.13 per share. This compares with an operating loss of $9.4
million and a net loss of $7.3 million, or $0.48 per share, for the three-month
period ended March 31, 1998 (the "1998 First Quarter").  The decrease in net
loss of $5.3 million for the 1999 First Quarter as compared to the 1998 First
Quarter resulted from increased revenues of $3.9 million, or 4.0% and decreased
operating expenses of $6.0 million, or 5.6% while block hours decreased by 8.4%.

Operating Revenues. The Company's operating revenues for the 1999 First Quarter
increased by $3.9 million, or 4.1%, to $100.7 million compared with operating
revenues of $96.7 million in the 1998 First Quarter.

Scheduled passenger service revenues for the 1999 First Quarter increased $12.9
million, or 24.5%, to $65.6 million from $52.7 million in 1998 First Quarter.
Scheduled passenger traffic (as measured in revenue passenger miles) for the
1999 the First Quarter increased by 13.1%, while capacity increased by 13.0%,
resulting in a small load factor increase to 76.1% compared to 76.0% in the 1998
First Quarter.  Higher operating revenues for the 1999 First Quarter were
attributable to a number of factors, including: (i) increased frequencies on
existing routes, (ii) inception of new domestic and international markets, (iii)
a 10.2% increase in yields per RPM and (iv) increased domestic market demand
during the 1999 First Quarter which resulted in an increase of $8.9 million, or
28.3%, in revenue over the 1998 First Quarter.

Commercial charter revenue for the 1999 First Quarter decreased by $9.0 million,
or 34.8%, to $16.8 million from $25.8 million for the 1998 First Quarter,
primarily due to decreased activities in Hajj charter operations from seven
aircraft in 1998 compared to four aircraft in 1999.

                                       12
<PAGE>
 
Military charter revenue for the 1999 First Quarter decreased by $1.6 million,
or 12.5%, to $11.4 million from $13.0 million for the 1998 First Quarter
primarily due to a temporary two-week suspension of the military contract during
the 1999 First Quarter.

Cargo charter revenue increased by 16.1% from $3.5 million to $4.0 million in
the 1999 First Quarter due to a new Aircraft, Crew, Maintenance and Insurance
(ACMI) agreement with an European airline. The increased revenue was partly
offset by a ground damage incident which occurred on one of the Company's two
B747-200 cargo aircraft on December 1, 1998. This damage was caused during the
fueling of the aircraft as a result of fire in the fuel truck which was owned
and operated by a third party. The repair to the aircraft is covered by
insurance and the Company is also seeking monetary compensation for the loss of
revenue as well as other expenses incurred by the Company in connection with the
loss of service of this aircraft. This aircraft will be back in service during
the 1999 Second Quarter. One of the Company's cargo aircraft has been inoperable
since February 1996, when the FAA promulgated certain ADs which restricted the
cargo carrying capacity of one of the Company's Boeing 747-100 cargo aircraft,
as well as nine other similarly converted Boeing 747-100 cargo aircraft operated
by other carriers. At that time, the Company decided to ground the aircraft
rather than operate it with restricted payload as required by such ADs. In order
to return the cargo capacity of such aircraft to what the Company believes to be
economically attractive levels, an FAA-approved modification plan will be
required. Such modifications are being designed and tested by the GATX-Airlog
Co. The FAA has approved a modification plan and the Company is presently
assessing the cost of such modification program. There is no assurance that such
aircraft will be returned to service.

Operating Expenses. The Company's operating expenses for the 1999 First Quarter
decreased  $6.0 million, or 5.6%, to $100.1 million from $106.1 million for the
1998 First Quarter.  Operating expenses, excluding fuel, depreciation and
amortization, decreased by 10.5% in the 1999 First Quarter while block hours
decreased by 8.4%.  This decrease in operating expenses resulted from lower
rental and maintenance expenses associated with the Company's reduction of
leased engines along with the purchase of two Boeing 747-200 aircraft in the
second half of 1998 from the existing lessors and the conversion of a third
Boeing B747-200 aircraft to a capitalized lease with another existing lessor in
the 1999 First Quarter.

Aircraft fuel expenses for the 1999 First Quarter increased $1.4 million, or
8.8%, to $16.9 million from $15.5 million for the 1998 First Quarter. The
increase in the 1999 First Quarter resulted from a 20.3% increase in consumption
due to a change of business mix whereby the Company, in 1999, is responsible for
fuel cost under a certain charter agreement compared with an ACMI agreement in
1998, partially offset by a 9.6% decrease in the cost of fuel.

Flight equipment rentals and insurance expenses for the 1999 First Quarter
decreased $1.6  million, or 18.7%, to $6.7 million from $8.3 million for the
1998 First Quarter. The decrease was attributable to lower rental associated
with the Company's reduction of leased engines along with the purchase of two
previously leased Boeing 747 aircraft in the second half of 1998 and the
conversion to a capital lease of a third Boeing 747 in the 1999 First Quarter.

<PAGE>
 
Maintenance costs for the 1999 First Quarter decreased $5.0 million, or 42.5%,
to $6.7 million from $11.7 million for the 1998 First Quarter. The decrease was
due primarily to lower maintenance reserves associated with the following
factors:  (i)  a one-time refund of $1.5 million previously paid by the Company
under the operating lease agreement  of a Boeing 747 aircraft as a result of
converting to a capital lease, (ii) the purchase of two Boeing 747 aircraft in
the second half of 1998 and (iii) a reduction in the number of engines leased by
the Company due to availability of its own engines from repair facilities.

Crew costs and other expenses for the 1999 First Quarter decreased $0.4 million,
or 5.7%, to $6.2 million from $6.6 million in the 1998 First Quarter. The
decrease was primarily due to an 8.4% decrease in total block hours flown,
partially offset by increases in pay rates.

Aircraft and traffic servicing expenses for the 1999 First Quarter increased
$0.8 million, or 4.1%, to $19.6 million from $18.9 million for the 1998 First
Quarter. This increase was primarily due to an 18.7% increase in scheduled
service block hours flown. Scheduled service block hours, where the Company is
responsible for all operating expenses, represented 60.0% of total block hours
flown for the 1999 First Quarter compared to 46.2% for the 1998 First Quarter.

Passenger servicing expenses for the 1999 First Quarter decreased $1.1 million,
or 8.7%, to $11.2 million from $12.3 million for the 1998 First Quarter. The
decrease  was due to an 8.4% decrease in total block hours flown, resulting in a
lower cabin crew cost, partially offset by higher cost associated with increased
scheduled service block hours as described above.

Promotion, sales and commission expenses for the 1999 First Quarter decreased
$1.3 million, or 9.6%, to $12.6 million from $13.9 million for the 1998 First
Quarter. The decrease was primarily due to a decrease in the average commission
rate to 11.5% in the 1999 First Quarter from 17.4% in the 1998 First Quarter.

General and administrative expenses for the 1999 First Quarter increased $0.5
million, or 11.0%, to $5.4 million from $4.9 million for the 1998 First Quarter.
As a percentage of operating revenue, general and administrative expenses for
the 1999 First Quarter was 5.3% compared to 5.0% for the 1998 First Quarter.

Depreciation and amortization expenses for the 1999 First Quarter increased $0.7
million, or 4.7%, to $14.8 million from $14.1 million for the 1998 First
Quarter. The increase was principally due to the purchase of two Boeing 747
aircraft in the second half of 1998 and capitalized engine overhauls.

Other Expenses and Income.  Interest expense for the 1999 First Quarter
increased by $0.4 million, or 10.5%, to $4.3 million from $3.9 million for the

balance in the 1999 First Quarter.

Liquidity and Capital Resources

The Company has historically financed its working capital and capital
expenditure requirements with cash flow generated from operations and through
lease, debt and equity financing.

The Company's cash, cash equivalents and certificates of deposit at March 31,
1999 and December 31, 1998 were $5.3 million and $3.8 million, respectively.
The Company generated cash from operations for the 1999 and 1998 First Quarters
of $13.4 million and $1.6 million, respectively.

Net cash used in investing activities was $7.4 million for the 1999 First
Quarter compared with $11.8 million for the 1998 First Quarter.  The Company's
expenditures for flight equipment were $11.3 million for the 1999 First Quarter
compared with $11.9 million for the 1998 First Quarter.  Expenditures for flight
equipment in the 1999 First Quarter included the capitalized engine overhauls
and heavy airframe maintenance (See Note 2 to the Financial Statements for
additional information regarding the financing of certain flight equipment
expenditures).

The Company has no unused lines of credit and must satisfy all of its working
capital, debt service and capital expenditure requirements from internally
generated funds, from external financing sources or from the sale of assets.  In
addition, the Company has no significant unpledged assets and, to the extent
that pledged assets are sold, the applicable financing arrangements generally
require the sale proceeds to be applied to repay the corresponding indebtedness.

As of March 31, 1999, the Company had negative working capital of $151.2 million
compared to negative working capital of $140.4 million as of December 31, 1998.
Historically, the Company has operated with a working capital deficit.

In September 1997, the Company entered into a Loan Agreement which extended the 
term of a line of credit with Heller Financial, Inc. (Heller) until September 
1999. The line of credit, which was increased from $15.0 million to $20.0 
million on April 14, 1999, decreasing to $15.0 million on August 31, 1999 and 
thereafter, is further limited to suppressed availability based on the value of 
the collateral. As of April 14, 1999, the Company has $19.3 million of 
availability based on the value of the collateral at such time. The line of 
credit is secured by accounts receivable, general intangibles, inventory, 
intellectual property, cash held in the Company's lock-box account, one spare 
airframe, aircraft spare parts and landing and gate rights. The Loan Agreement 
provides that the Company shall not, directly or indirectly, create or become 
liable in respect of any indebtedness, with certain specified exceptions. 

From time to time during 1998 and the first quarter of 1999, the Company has 
been in default under certain provisions of the Loan Agreement. The Company has 
entered into amendments with Heller waiving such defaults and is currently in 
compliance with such provisions as they have been amended. 

                                       15

Since February 1998, the Company has entered into nine amendments to the Loan 
Agreement providing, among other things, for (i) changes in the maximum amount 
of the revolving loan during different periods; (ii) subordination of loans made
to the Company by officers and directors; (iii) increases to the spread between 
the amount of collateral required and the amount of available borrowing under 
the Loan Agreement; (iv) modification of the financial covenant relating to the 
Company's Tangible Net Worth (as defined therein) to facilitate compliance by 
the Company; and (v) increases in the interest rate from Prime (as defined 
therein) plus 0.75% to Prime plus 1.50% (9.25% at December 31, 1998). Through a 
combination of the fourth amendment on May 14, 1998 and the sixth amendment on 
July 13, 1998, the Company and Heller agreed to modify the Tangible Net Worth 
covenant in the Loan Agreement by reducing the amount of Tangible Net Worth the 
Company is required to maintain from $47.0 million prior to August 31, 1998 and 
$55.0 million thereafter to $35.0 million through May 1998, $38.0 million for 
June 1998, $47.5 million through August 1, 1998 and $55.0 million from August 
31, 1998 and thereafter. On June 1, 1998, the fifth amendment permanently 
limited the maximum amount of borrowings under the facility to $15.0 million 
beginning on June 29, 1998, a decrease from the $25.0 million maximum amount 
originally permitted. The sixth amendment to the Loan Agreement waived defaults 
resulting from the repayment of the 12% Note (as defined herein), the issuance 
of the Nachtoml Note (as defined herein) and the defaults referred to below. On 
August 27, 1998, the seventh amendment to the Loan Agreement between the Company
and Heller modified again the Tangible Net Worth covenant in the Loan Agreement 
by reducing the amounts of Tangible Net Worth the Company is required to 
maintain to $44.5 million in July 1998, $45.0 million from August 1998 through 
March 1999 and to $50.0 million in April and May 1999. On April 14, 1999, the 
eighth amendment to this Loan Agreement increased the maximum amount of 
borrowings under the facility to (i) $20.0 million from April 14, 1999 to May 
30, 1999, (ii) $19.0 million from May 31, 1999 to June 29, 1999, (iii) $18.0 
million from June 30, 1999 to July 30, 1999, (iv) $16.0 million from July 31, 
1999, to August 30, 1999, and (v) $15.0 million on August 31, 1999 and 
thereafter. In addition, under the eighth amendment, the Company agreed to 
maintain at all times an amount of excess collateral available under the 
facility of $7.0 million, plus an additional $0.5 million for each additional 
$1.0 million borrowed above $15.0 million. This eighth amendment also waived a
covenant default relating to late payments of excise taxes, which as of April
15, 1999, the Company has paid in full. On April 15, 1999, the ninth amendment
to the loan agreement between the Company and Heller further modified the
Tangible Net Worth covenant in the loan agreement by reducing the amounts the
Company is required to maintain to $45.0 million from March 1999 through June
1999 and $50.0 million thereafter through September 1999.
 
In January 1998, the Company entered into a $15.0 million loan agreement with a 
commercial financial institution secured by twelve Pratt & Whitney engines, of 
which $11.3 million was used to pay the balance remaining on two previous 
agreements with the same commercial financial institution. On February 8, 1999, 
the aggregate balance of $6.8 million outstanding on this note was paid from the
proceeds of a sale and leaseback transaction with another commercial financial 
institution. Under this capitalized sales and leaseback arrangement, the Company
is required to make fixed monthly payments of approximately $0.3 million 
consisting of principal and interest at 10.6% through January 2004. 

                                      16

In February and March 1998, the Company borrowed $6.0 million which bears 
interest at a rate of 12% (the "12% Note") from Funding Enterprises, LLC, a 
limited liability Company in which the Company's Chairman and former President 
were members. On July 1, 1998, the Company discharged its obligations under the
12% Note by issuing a new note (the "Nachtomi Note"), due August 7, 1998, to the
Company's Chairman in the principal amount of $3.0 million and repaying the 
balance of the 12% Note in cash. The Nachtomi Note originally provided for 
interest at an annual rate of 12.0%, increasing to 15% after August 7, 1998. The
Nachtomi Note was amended on August 6, 1998, establishing an annual interest 
rate of 12% after August 7, 1998, as well as a new maturity date of April 30, 
1999. On April 14, 1999, the Nachtomi Note was amended to extend the maturity 
date to January 1, 2000. In connection with the 12% Note, warrants for the 
purchase of 1.2 million shares of Common Stock of the Company were issued with 
an exercise price of $5.00. The warrants expire in February 2008.

From September 1997 through March 1998, the Company entered into a finance 
agreement involving the conversion and refurbishment of Pratt & Whitney engines.
In connection with this transaction, eight engines were financed for $38.4 
million with interest at prime plus 2%. In September 1998, the lender agreed to 
increase the loan to include $4.2 million relating to certain engines previously
overhauled. The loan was restructured and now requires a total monthly payment 
of $1.5 million through March 1999 and $2.0 million through July 1999 and $2.5 
million through August 2000 which allows the Company to repair/overhaul 
additional engines currently at the repair facility with interest at 6% going up
to a maximum of 9% per annum. Under this restructuring agreement, the Company 
was unable to make required payments for January through March 1999 amounting to
$4.5 million. The Company has reached an understanding with the financial 
institution whereby this amount will be paid by September 1999.

In July 1998, the Company did not meet the minimum net worth requirements of an 
operating lease agreement entered into in connection with a sale and leaseback 
transaction, but has obtained a waiver of that provision through July 31, 1999. 
In addition, on April 14, 1999, the Company obtained waivers under certain lease
and debt agreements for a covenant default relating to the late payment of 
excise taxes, which as of April 15, 1999, the Company has paid in full. During 
1998, the Company obtained agreements with other lessors for deferred or revised
payment terms for approximately $8.1 million of lease and maintenance reserve 
payments. As of March 31, 1999, the outstanding amount is approximately $2.3 
million. In addition, the Company agreed with certain of its vendors and 
suppliers to extend payment terms, and has, in some cases, obtained payment 
extensions with respect to certain of the Company's current obligations.

On July 15, 1998, the Company purchased an existing leased aircraft from a 
lessor for a purchase price of $13.5 million of which a credit of $6.0 million 
was given by the lessor to the Company for the payment of maintenance reserves 
paid during the lease period and a balance of $7.5 million was financed by the 
same lessor. In addition, the lessor waived all previously outstanding rent and 
maintenance reserves through June 30, 1998 amounting to $1.4 million. This loan 
requires a monthly payment of approximately $50,000 of interest only starting 
October 1998 through May 1999 and then a total monthly payment of approximately 
$0.4 million including principal and interest through March 2001.

                                      17

On August 13, 1998, the Company restructured three existing loans with a
financial institution under which the Company was required to pay a total
monthly principal payment of $1.5 million. Under the terms of these restructured
Aircraft Loan and Security Agreements, the Company is required to pay an
aggregate monthly principal payment of $0.5 million plus interest through March
1999, which will pay off one of the three loans and the remaining two loans will
require a monthly principal and interest payment, commencing April 1999, of $1.2
million and $0.5 million through December 2002 and February 2003, respectively.

On November 13, 1998, the Company purchased another existing leased aircraft 
from a lessor for a purchase price of $21.0 million of which $20.0 million was 
financed by the same lessor. The loan is comprised of two notes of $10.0 million
each and requires a fixed total monthly payment of $105,000 each consisting of 
principal and interest. 

On December 31, 1998, the Company purchased three Pratt and Whitney engines from
a vendor for a total purchase price of $8.1 million of which $6.7 million was 
financed by the same vendor. The loan, which bears interest at 9.0% per annum, 
is for three years and requires a fixed monthly payment of $.2 million 
consisting of principal and interest starting February 1, 1999.

On March 2, 1999, the Company purchased an existing leased aircraft for $24.5 
million under a capitalized lease arrangement from the existing lessor. The 
Company is required to make fixed monthly payments of approximately $0.4 million
consisting of principal and interest at 9.7% through September 2006.

On March 24, 1999, the Company purchased four Pratt & Whitney engines from a 
commercial financial institution for a total purchase price of $10.8 million of 
which $9.1 million was financed by the same financial institution. The loan, 
which bears interest at 10.0% per annum, is for a period of eighteen months and 
requires a fixed monthly payment of $0.5 million consisting of principal and 
interest starting April 23, 1999. 

The Company has entered into a letter of intent with International Lease Finance
Corp. to lease two new Boeing 777 aircraft for an initial term of ten years. 
If a definitive agreement is executed, the Company will be required to pay $4.8
million in deposits for the two leased aircraft, of which $0.4 million is due
during the first half of 1999. The deposits are refundable, subject to certain
conditions, at the end of the lease term.

The Company is highly leveraged and has and will continue to have significant
debt service obligations.  The Company currently expects that capital
expenditures for 1999 will total approximately $40.0 million, included will be
expenditures for scheduled heavy airframe maintenance and engine overhaul on the
Company's aircraft.

To the extent that the Company's access to capital is constrained, the Company
may not be able to make certain capital expenditures, meet certain other
requirements or continue to implement certain other aspects of its strategic
plan.  The Company's ability to make scheduled principal and interest payments
and to refinance its indebtedness and to meet its other obligations and future
capital commitments will be dependent 

                                      18
<PAGE>

upon its financial and operating performance, which is subject to general
economic conditions and to financial, business and other factors, including
factors beyond its control. Management believes that the Company's cash flow
from its operations and financing activities should be sufficient in the next
twelve months to meet the Company's debt service and other obligations, future
capital commitments and liquidity requirements. However, the airline industry in
general, and the Company in particular, are subject to significant risks and
uncertainties, therefore, there can be no assurance that the Company's operating
results and financing activities will be sufficient in the foreseeable future to
meet such obligations and commitments.

In an effort to conserve cash, the Company suspended cash dividends on its
Common Stock after the third quarter of 1996.


Year 2000

The Year 2000 problem exists because many computer programs use only the last
two digits to refer to a year.  This convention could affect date-sensitive
calculations that treat "00" as the year 1900, rather than 2000.  An additional
issue is that 1900 was not a leap year, whereas the Year 2000 is.  Therefore,
some programs may not properly provide for February 29, 2000.  This anomaly
could result in miscalculations when processing critical date-sensitive
information after December 31, 1999.

The Company strengthened its MIS Department with the hiring of additional
computer experts who are familiar with information system issues confronting
both the Company in particular and the airline industry in general.  The
Company's comprehensive Year 2000 initiative is managed by this new internal MIS
team.  The team's activities are designed to ensure that there is no adverse
effect on the Company's core business operation and that transactions with
customers, suppliers and financial institutions are fully supported.  The
Company has determined that due to its most recent and near term software
upgrades, its internal systems will function properly with respect to dates in
the Year 2000 and beyond.  The Company has initiated discussions with its
significant suppliers, large customers and financial institutions to ensure that
those parties have appropriate plans to remediate Year 2000 issues where their
systems interface with the Company's systems or otherwise impact its operations.
The Company is assessing the extent to which its operations are vulnerable
should those organizations fail to remediate properly their computer systems.
While the Company believes its planning efforts are adequate to address its Year
2000 concerns, there can be no guarantee that the systems of other companies or
governmental agencies on which the Company's systems and operations rely will be
converted on a timely basis and, if not so converted, will not have a material
adverse effect on the Company's business.

The Company's new MIS team is assessing the need to develop remediation
contingency plans and business resumption contingency plans specific to the Year
2000.  Remediation contingency plans address the actions to be taken if the
current approach to remediating a system is falling behind schedule or otherwise
appears in jeopardy of failing to deliver a Year 2000 ready system when needed.
Business resumption contingency plans address the actions that would be taken if
critical

                                      19

business functions can not be carried out in the normal manner upon entering the
next century due to system or supplier failure.

The Company, as an International Air Transport Association (IATA) member
airline, is a participant in the "IATA Year 2000 Project". The IATA Year 2000
Project is an initiative to increase the awareness of third party suppliers and
to assess/promote their Year 2000 preparedness.  Working closely with The
Airports Council International, the International Civil Aviation Organization,
(ICAO) and other industry organizations, IATA has developed and piloted a
standard methodology to assess Year 2000 readiness. The project  provides
training on how to use the methodology, and tracks the status of remedial
programs so that problems can be identified early.  IATA estimates that the cost
of the Project will be approximately $20 million, of which the Company's pro
rata share is approximately $67,000.  The Company does not expect the total cost
of its Year 2000 initiatives to have a material adverse effect on the Company's
business.

                           ENGINE SECURITY AGREEMENT
                           -------------------------

     TOWER AIR, INC., a Delaware corporation (the "Debtor"), for valuable
consideration, the receipt of which hereby is acknowledged, hereby transfers,
assigns and pledges to UNICAPITAL AIRCRAFT ENGINE GROUP, INC., a Delaware
corporation (the "Secured Party"), and grants to the Secured Party a security
interest in the following collateral, wherever located, now existing and
hereafter arising or coming into existence (the "Collateral"):

        (a)  Pratt & Whitney JT9D-7J engine bearing manufacturer's serial number

attachments, additions and accessions thereto, and added and substituted parts,
equipment and repairs now or hereafter placed upon such property, whether
because of necessary repairs or otherwise;

        (b)  Pratt & Whitney JT9D-7J engine bearing manufacturer's serial number
662412, which has 750 or more rated takeoff horsepower, together with all
attachments, additions and accessions thereto, and added and substituted parts,
equipment and repairs now or hereafter placed upon such property, whether
because of necessary repairs or otherwise;

        (c)  Pratt & Whitney JT9D-7J engine bearing manufacturer's serial number
662792, which has 750 or more rated takeoff horsepower, together with all
attachments, additions and accessions thereto, and added and substituted parts,
equipment and repairs now or hereafter placed upon such property, whether

        (d)  Pratt & Whitney JT9D-7J engine bearing manufacturer's serial number
686101, which has 750 or more rated takeoff horsepower, together with all
attachments, additions and accessions thereto, and added and substituted parts,
equipment and repairs now or hereafter placed upon such property, whether
because of necessary repairs or otherwise; and

        (e)  The proceeds and products of the foregoing in whatever form the
same may be, for the purpose of securing the payment to the Secured Party and
the performance by the Debtor of the following ("Obligations"): the obligations,
covenants and duties owing to the Secured Party from the Debtor under the
Aircraft Engine Purchase Agreement, dated as of February 8, 1999, between the
Debtor and the Secured Party, including the Secured Party's obligations under

     The Debtor further warrants to and agrees with the Secured Party as
follows:

                                       1
<PAGE>
 
     1.  Preservation of Collateral. The Debtor will keep the Collateral in good
         --------------------------                                             
order and repair at all times, will use same with reasonable care and caution,
will not part with ownership thereof and will give representatives of the
Secured Party access thereto at all reasonable times upon reasonable notice to
the Debtor.  The Debtor will not part with possession of the Collateral nor
lease or hire out same without the written consent of the Secured Party which
shall not unreasonably be withheld (provided, that so long as no Event of
Default is continuing, the Debtor, without the written consent of the Secured
Party, may, subject and subordinate in all respects to this Agreement and the
Secured Party's rights hereunder, (i) sublease the Collateral to any affiliate
of the Debtor; (ii) subject the Collateral to normal interchange or pooling
agreements with responsible air carriers entered into by the Debtor in the
ordinary course of business; and (iii) deliver possession of the Collateral to a
Federal Aviation Administration-approved maintenance facility for testing,
service, repair, maintenance or overhaul work).  The Debtor will not knowingly
use, or permit the Collateral to be used, in violation of any federal, state,
county or municipal law or regulation or for any unlawful purpose whatsoever.

     2.  Insurance.
         --------- 

          2.1  The Debtor will keep the Collateral insured in respect of both
ground and flight risk under its fleet policy on terms and conditions
substantially similar to those in effect on the date hereof.  All such insurance
policies will name the Secured Party as an additional insured and, where
applicable, as loss payee under a loss payable endorsement satisfactory to thc
Secured Party.  The Debtor will deliver to the Secured Party certificates
representing such insurance policies upon the execution hereof.  All amounts
payable in settlement of insurance losses not constituting a total loss shall be
used to repair, replace or restore the Collateral.  If any Event of Default
shall then be continuing, all amounts payable in settlement of a total loss may
be applied, at the Secured Party's option, to the Obligations in the order
determined by the Secured Party.

          2.2  The Debtor will at its expense carry or cause to be carried
public liability (including, without limitation, contractual liability and
passenger legal liability), payable in U.S. dollars, with respect to the any
airframe upon which any item of Collateral is installed (i) in amounts, of the
type and covering the risks reasonably acceptable to the Secured Party, but in
no event shall the amount of such insurance be less than that which at the time
is customarily carried with respect to similar aircraft by corporations engaged
in the same or similar business and similarly situated with the Debtor, and (ii)
with insurers of recognized international responsibility reasonably satisfactory
to the Secured Party.

          2.3  Any policies of insurance required pursuant to either paragraph
2.2 or 2.3 above shall: (i) name the Secured Party as an additional named
insured, but without the Secured Party being thereby liable for payment of
premiums; (ii) provide that in respect of the interest of the Secured Party in
such policies the insurance shall not be invalidated by any action or inaction
of the 

                                       2
<PAGE>
 
Debtor and shall insure the interest of the Secured Party regardless of any
breach or violation by the Debtor of any warranty, declaration or condition
contained in such policies; and (iii) provide that if such insurance is
canceled, such cancellation shall not be effective as to the Secured Party for
thirty (30) days after receipt by the Secured Party of written notice from the
insurers of such cancellation.

          2.4  On or prior to the date hereof and annually thereafter on or
prior to the anniversary of the date hereof, the Debtor will furnish to the
Secured Party a report signed by a firm of independent aircraft insurance
brokers, appointed by the Debtor and acceptable to the Secured Party, describing
in reasonable detail the insurance then carried and maintained on or with
respect to the Collateral and stating that in the opinion of such firm such
insurance complies with the terms of this Section 2 and is adequate to protect
the interests of the Debtor and the Secured Party. The Debtor will cause such
firm to advise the Secured Party in writing (i) promptly of any default in the
payment of any premium and of any other act or omission on the part of the
Debtor of which such firm has knowledge and which might invalidate or render
unenforceable, in whole or in part, any insurance on the Collateral and (ii) at
least 30 days prior to the expiration or termination date of any insurance
carried and maintained on the Collateral hereunder if such insurance has not
been renewed by such date in accordance with the terms hereof

     3.  Payment of Expenses by the Secured Party.  At its option, if the Debtor
         ----------------------------------------                               
fails to do so, the Secured Party may discharge taxes, liens, security interests
or such other encumbrances as may attach to the Collateral, may pay for the
insurance on the Collateral specified in Section 2 hereof and may pay for the
maintenance, appraisal or reappraisal, and preservation of the Collateral, as
determined by the Secured Party to be reasonably necessary.  The Debtor will
reimburse the Secured Party on demand for any payment so made or any expense
incurred by the Secured Party pursuant to the foregoing authorization, and the
Collateral also will secure any advances or payments so made or expenses so
incurred by the Secured Party.

     4.  Representations, Warranties and Covenants.  The Debtor represents,
         -----------------------------------------                         
warrants and covenants to the Secured Party that: (a) the Debtor is the sole and
lawful owner of the Collateral and has not made any prior sale, pledge,
encumbrance, assignment or other disposition of any of the Collateral, and the
same is free from all encumbrances and rights of setoff of any kind (except for
liens for taxes not yet due and payable and statutory and common law liens of
mechanics, workmen and materialmen incurred in the ordinary course of business
for sums not yet due and payable ("Permitted Encumbrances")); (b) except as
herein provided, the Debtor will not hereafter without the prior written consent
of the Secured Party sell, pledge, encumber, assign or otherwise dispose of any
of the Collateral or permit any right of setoff, lien or security interest to
exist thereon except for Permitted Encumbrances and except to the Secured Party;
(c) the Debtor will defend the Collateral against all claims and demands of all
persons at any time claiming the same or any interest therein.

                                       3
<PAGE>
 
     5.  Financing Statements; Documents.  At the request of the Secured Party,
         -------------------------------                                       
the Debtor will join with the Secured Party in executing financing statements
pursuant to the Uniform Commercial Code and/or any documents required or
permitted by the United States Department of Transportation, Federal Aviation
Administration, in form satisfactory to the Secured Party and will pay the cost
of filing such documents in all public offices where filing is deemed necessary
or desirable by the Secured Party.  The Debtor will execute and deliver to the
Secured Party from time to time such supplemental assignments or other
instruments as the Secured Party may require for the purpose of confirming the
Secured Party's interest in the Collateral.  The Debtor hereby authorizes the
Secured Party to execute and file on behalf of the Debtor all financing
statements and documents deemed necessary or appropriate to perfect the Secured
Party's interest in the Collateral.

     6.  Default.
         ------- 

          6.1  Upon the occurrence of any Event of Default (as defined in the
Note) and the lapse of any notice or cure period provided in such Note with
respect to such default, the Secured Party is authorized in its discretion to
declare the Note immediately due and payable without demand or notice to the
Debtor and may exercise any one or more of the rights and remedies granted
pursuant to this Agreement or given to a secured party under the Uniform
Commercial Code as in effect in the State of New York (irrespective of whether
the Uniform Commercial Code applies to the Collateral), including but not
limited to the right to take possession and sell, lease or otherwise dispose of
the Collateral and, at its option, operate, use or exercise any rights of
ownership pertaining to the Collateral as the Secured Party deems necessary to
preserve the value and receive the benefits of the Collateral.  Upon the
occurrence of an Event of Default, and so long as the same shall be continuing,
the Secured Party may, so far as the Debtor can give authority therefor, enter
upon any premises on which the Collateral or any part thereof may be situated
and take possession of and remove the same therefrom.  The Secured Party may
require the Debtor to make the Collateral available to the Secured Party at a
place to be designated by the Secured Party that is reasonably convenient to
both parties.  The Debtor waives all claims for damages by reason of any
seizure, repossession, retention, use or sale of the Collateral under the terms
of this Agreement, except to the extent caused by the Secured Party's willful
misconduct or gross negligence.

          6.2  The net proceeds arising from the disposition of the Collateral
after deducting reasonable expenses incurred by the Secured Party in connection
therewith will be applied to the Obligations in the order determined by the
Secured Party.  If any excess remains after the discharge of all of the
Obligations, the same will be paid to the Debtor.  If after exhausting all of
the Collateral, there should be a deficiency, the Debtor will be liable therefor
to the Secured Party, provided, however, that nothing contained herein will
obligate the Secured Party to proceed 

                                       4
<PAGE>
 
against the Collateral prior to making a claim against the Debtor or any other
party obligated under the Obligations or prior to proceeding against any other
collateral for the Obligations.

          6.3  Whenever notice is required by law to be sent by the Secured
Party to the Debtor of any sale, lease or other disposition of the Collateral,
ten days written notice sent to the Debtor's address set forth below will be
reasonable.

          6.4  If any demand is made at any time upon the Secured Party for the
repayment or recovery of any amount received by it in payment or on account of
any of the Obligations and if the Secured Party repays all or any part of such
amount, the Debtor will be and remain liable for the amounts so repaid or
recovered to the same extent as if never originally received by the Secured
Party.

     7.  Event of Loss.  If an Event of Loss (as defined below) shall occur, the
         -------------                                                          
Debtor will forthwith notify the Secured Party thereof in writing and will, not
later than 60 days after the occurrence of such Event of Loss, prepay to the
Secured Party the aggregate unpaid principal amount of Note, together with
interest on such aggregate principal amount accrued to the date of prepayment
and any other amounts owing by the Debtor under the Obligations.  For purposes
hereof, the term "Event of Loss" shall mean any of the following events with
respect to any item of Collateral: (i) loss of such item of Collateral or of the
use thereof due to theft, disappearance, destruction, damage beyond repair or
rendition of such property permanently unfit for normal use for any reason; (ii)
any damage to such item of Collateral which results in an insurance settlement
with respect to such item of Collateral on the basis of a total loss,
constructive loss or agreed loss; (iii) the condemnation, confiscation or
seizure of, or requisition of title to or use of, such item of Collateral by
private persons or governmental or purported governmental authority (de facto or
de jure); (iv) as a result of any rule, regulation, order or other action by the
Federal Aviation Administration (of the United States of America or any other
country at any time having jurisdiction) or other governmental body having
jurisdiction, the use of such item of Collateral in the normal course of
interstate air transportation shall have been prohibited for a period of two (2)
consecutive months; or (v) the inability, for any reason whatsoever, of the
Secured Party to obtain possession of any item of Collateral within thirty (30)
days of delivery of notice to the Secured Party of the occurrence of an Event of
Default under the Note.

     8.  Rights of Secured Party; Power of Attorney.  The Debtor hereby
         ------------------------------------------                    
irrevocably constitutes and appoints the Secured Party and any officer thereof,
with full power of substitution, as its true and lawful attorney-in-fact with
full irrevocable power and authority in the place and stead of the Debtor or in
its name, from time to time in the Secured Party's discretion for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments which may be necessary or
desirable to 

                                       5
<PAGE>
 
accomplish the purposes of this Agreement and, without limiting the generality
of the foregoing, the Debtor hereby gives the Secured Party the power and right,
on behalf of the Debtor, after an Event of Default shall have occurred and so
long as the same shall be continuing, and without notice to or assent by the
Debtor, to do the following:

          8.1  to receive payment of, endorse, and receipt for, any and all
monies, claims and other amounts due and to become due at any time in respect of
or arising out of the Collateral;

          8.2  to commence and prosecute any suits, actions or proceeding at law
or in equity in any court of competent jurisdiction to collect any of the
Collateral and to enforce any other right in respect of the Collateral;

          8.3  to settle, compromise or adjust any suit, action or proceeding
described above, and, in connection therewith, to give such discharges or
releases as the Secured Party may deem appropriate; and

          8.4  generally to sell, transfer, pledge, make any agreement with
respect to or otherwise deal with any of the Collateral as fully and completely
as though the Secured Party were the absolute owner thereof for all purposes,
and to do, at the Secured Party's option, at any time, or from time to time, all
acts and things which the Secured Party deems necessary to protect or preserve
the Collateral and the Secured Party's security interest and rights therein in
order to effect the intent of this Agreement, all as fully and effectively as
the Debtor might do.

The Debtor hereby ratifies all that such attorneys shall lawfully do or cause to
be done by virtue hereof.  This power of attorney is a power coupled with an
interest will be irrevocable and shall terminate only upon payment in full of
the Obligations and the termination of this Agreement.  The powers conferred
upon the Secured Party hereunder are solely to protect the Secured Party's
interests in the Collateral and will not impose any duty upon it to exercise any
such powers.  The Secured Party will have no obligation to preserve any rights
of any third parties in the Collateral.  The Secured Party will be accountable
only for amounts that it actually receives as a result of the exercise of such
powers, and neither it nor any of its officers, directors, employees or agents
will be responsible to the Debtor for any action taken or omitted to be taken in
good faith or in reliance on the advice of counsel except for its own gross
negligence or willful misconduct.

     9.  Miscellaneous.
         ------------- 

          9.1  Fees and Expenses.  The Debtor will promptly (and in any event
               -----------------                                             
within 30 days after its receipt of an invoice or statement therefor) pay all
costs and expenses (including, without limitation, reasonable fees and
disbursements of counsel) suffered or incurred by the Secured Party in

<PAGE>
 
with its enforcement of the payment and performance of the Obligations or any
other sum due to it under this Agreement, or any of its other rights hereunder
or thereunder. The provisions of this Section shall survive the payment of the
Obligations and the termination of this Agreement.

          9.2  Right of Set-Off.  In addition to any rights now or hereafter
               ----------------                                             
granted under applicable law or otherwise and not by way of limitation of any
such rights, upon the occurrence of any Event of Default and so long as the same
shall be continuing, the Secured Party is hereby authorized at any time or from
time to time, without presentment, demand, protest or other notice of any kind
to the Debtor or to any other person, and such notice herein hereby expressly
waived, to set off and to apply any and all deposits (general or special) and
any other indebtedness at any time held or owing by the Secured Party to or for
the credit or the account of the Debtor, including the Maintenance Reserves (as
defined in the Obligations) against and on account of the obligations and
liabilities of the Debtor to the Secured Party under this Agreement or the
Obligations, including, without limitation, all other claims of any nature or
description arising out of or connected with this Agreement, the Obligations or
any other Security Document, whether or not the Secured Party shall have made
any demand therefor and although said obligations, liabilities or claims, or any
of them, shall be contingent or unmatured.

hereof and prior to the Delivery Date, Purchaser shall have the right to delay

Purchaser or Seller shall have the right to terminate this Agreement by giving

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof or rendering unenforceable such provision in any other

hereby waive any provision of law which renders any provision hereof prohibited

         ----------------------------------------- 

          2.1  The Debtor represents and warrants to the Secured Party that all
things have been done to make this Agreement and the Lease Agreement, when
executed by the Debtor, the legal, valid and binding obligation of the Debtor
enforceable against the Debtor in accordance with their respective terms, except
as 
<PAGE>
 
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws affecting creditors' rights generally and, to the extent
that certain remedies require or may require enforcement by a court of equity,
by such principles of equity (regardless of whether such enforceability is
considered in a proceeding at law or in equity) as a court having jurisdiction
may impose.

         2.2  The Debtor represents, warrants and covenants to the Secured
Party that the Debtor (a) has not made any prior sale, pledge, encumbrance,
assignment or other disposition of the Debtor's interest in any of the
Collateral, and the same is free from all encumbrances and rights of setoff of
any kind (except for liens for taxes not yet due and payable and statutory and
common law liens of mechanics, workmen and materialmen incurred in the ordinary
course of business for sums not yet due and payable ("Permitted Encumbrances"));
(b) except as herein provided, the Debtor will not hereafter without the prior
written consent of the Secured Party sell, pledge, encumber, assign or otherwise
dispose of the Debtor's interest in any of the Collateral or permit any right of
setoff, lien or security interest to exist thereon except for Permitted
Encumbrances and except to the Secured Party; (c) the Debtor will defend its
interest in the Collateral against all claims and demands of all persons at any
time claiming the same or any interest therein.

          2.3  The Debtor represents, warrants and covenants to the Secured
Party that so long as this Agreement remains in effect the Debtor shall duly
observe and perform all of its obligations under the Lease Agreement and pay to
the Secured Party all amounts due and owing hereunder and under the provisions

Section 3 thereof; (b) service, inspect, test, maintain, overhaul and repair
each Engine pursuant to Section 6 thereof; (c) preserve and protect the Secured
Party's rights in the Engines, maintain possession of the Engines and certain
other related obligations pursuant to Section 7 thereof; and (d) maintain
insurance on the Engines pursuant to Section 9 thereof, are specifically
incorporated herein and made a part hereof.

     3.  Payment of Expenses by the Secured Party.  At its option, if the Debtor
         ----------------------------------------                               
fails to do so, the Secured Party may discharge taxes, liens, security interests
or such other encumbrances as may attach to the Collateral, may pay for the
insurance on the Collateral specified in Section 9 of the Lease Agreement and
may pay for the maintenance, appraisal or reappraisal, and preservation of the
Collateral, as determined by the Secured Party to be reasonably necessary.  The
Debtor will reimburse the Secured Party on demand for any payment so made or any
expense incurred by the Secured Party pursuant to the foregoing authorization,
and the Collateral also will secure any advances or payments so made or expenses
so incurred by the Secured Party.
<PAGE>
 
     4.  Financing Statements; Documents.  At the request of the Secured Party,
         -------------------------------                                       
the Debtor will join with the Secured Party in executing financing statements
pursuant to the Uniform Commercial Code and/or any documents required or
permitted by the United States Department of Transportation, Federal Aviation
Administration, in form satisfactory to the Secured Party and will pay the cost
of filing such documents in all public offices where filing is deemed necessary
or desirable by the Secured Party.  The Debtor will execute and deliver to the
Secured Party from time to time such supplemental assignments or other
instruments as the Secured Party may require for the purpose of confirming the
Secured Party's interest in the Collateral.  The Debtor hereby authorizes the
Secured Party to execute and file on behalf of the Debtor all financing
statements and documents deemed necessary or appropriate to perfect the Secured
Party's interest in the Collateral.

     5.  Default.
         ------- 

          5.1  Upon the occurrence of any Event of Default (as defined in the
Lease Agreement) and the lapse of any notice or cure period provided in the
Lease Agreement with respect to such default, the Secured Party may exercise any
one or more of the rights and remedies granted pursuant to this Agreement or
given to a secured party under the Uniform Commercial Code as in effect in the
State of New York (irrespective of whether the Uniform Commercial Code applies
to the Collateral), including but not limited to the right to take possession
and sell, lease or otherwise dispose of the Collateral and, at its option,
operate, use or exercise any rights of ownership pertaining to the Collateral as
the Secured Party deems necessary to preserve the value and receive the benefits
of the Collateral.  Upon the occurrence of an Event of Default, and so long as
the same shall be continuing, the Secured Party may, so far as the Debtor can
give authority therefor, enter upon any premises on which the Collateral or any
part thereof may be situated and take possession of and remove the same
therefrom.  The Secured Party may require the Debtor to make the Collateral
available to the Secured Party at a place to be designated by the Secured Party
that is reasonably convenient to both parties.  The Debtor waives all claims for
damages by reason of any seizure, repossession, retention, use or sale of the
Collateral under the terms of this Agreement, except to the extent caused by the
Secured Party's willful misconduct or gross negligence.

          5.2  The net proceeds arising from the disposition of the Collateral
after deducting reasonable expenses incurred by the Secured Party in connection
therewith will be applied to the Obligations in the order determined by the
Secured Party.  If after exhausting all of the Collateral, there should be a
deficiency, the Debtor will be liable therefor to the Secured Party, provided,
however, that nothing contained herein will obligate the Secured Party to
proceed against the Collateral prior to making a claim against the Debtor or any
other party obligated under the Obligations or prior to proceeding against any
other collateral for the Obligations.
<PAGE>
 
          5.3  Whenever notice is required by law to be sent by the Secured
Party to the Debtor of any sale, lease or other disposition of the Collateral,
ten days written notice sent to the Debtor's address set forth below will be
reasonable.

          5.4  If any demand is made at any time upon the Secured Party for the
repayment or recovery of any amount received by it in payment or on account of
any of the Obligations and if the Secured Party repays all or any part of such
amount, the Debtor will be and remain liable for the amounts so repaid or
recovered to the same extent as if never originally received by the Secured
Party.

     6.  Event of Loss.  If an Event of Loss (as defined in the Lease Agreement)
         -------------                                                          
shall occur, the Debtor will forthwith notify the Secured Party thereof in
writing and will, not later than 60 days after the occurrence of such Event of
Loss, pay to the Secured Party the Stipulated Loss Value (as defined in the
Lease Agreement).

     7.  Rights of Secured Party; Power of Attorney.  The Debtor hereby
         ------------------------------------------                    
irrevocably constitutes and appoints the Secured Party and any officer thereof,
with full power of substitution, as its true and lawful attorney-in-fact with
full irrevocable power and authority in the place and stead of the Debtor or in
its name, from time to time in the Secured Party's discretion for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Agreement and, without limiting the
generality of the foregoing, the Debtor hereby gives the Secured Party the power
and right, on behalf of the Debtor, after an Event of Default shall have
occurred and so long as the same shall be continuing, and without notice to or
assent by the Debtor, to do the following:

          7.1  to receive payment of, endorse, and receipt for, any and all
monies, claims and other amounts due and to become due at any time in respect of
or arising out of the Collateral;

          7.2  to commence and prosecute any suits, actions or proceeding at law
or in equity in any court of competent jurisdiction to collect any of the
Collateral and to enforce any other right in respect of the Collateral;

          7.3  to settle, compromise or adjust any suit, action or proceeding
described above, and, in connection therewith, to give such discharges or
releases as the Secured Party may deem appropriate; and

          7.4  generally to sell, transfer, pledge, make any agreement with
respect to or otherwise deal with any of the Collateral without regard to any
interest the Debtor may have in  the Collateral pursuant to the Lease Agreement
for all purposes, and to do, at the Secured Party's option, at any time, or from
time to time, all acts and things which the Secured Party deems necessary to
protect or 
<PAGE>
 
preserve the Collateral and the Secured Party's security interest and rights
therein in order to effect the intent of this Agreement, all as fully and
effectively as the Debtor might do.

The Debtor hereby ratifies all that such attorneys shall lawfully do or cause to
be done by virtue hereof.  This power of attorney is a power coupled with an
interest will be irrevocable and shall terminate only upon payment in full of
the Obligations and the termination of this Agreement.  The powers conferred

6.   REPRESENTATIONS AND WARRANTIES

     A.  Seller hereby represents and warrants to Purchaser that:

     (1)  Seller is a corporation duly organized, validly existing and in good

          the Delivery Date.

     (3)  This Agreement has been duly authorized, executed and delivered by
          Seller and is a valid, enforceable and binding obligation of Seller,
          except as such enforceability may be limited by applicable bankruptcy,

          creditors generally, and except as enforceability may be subject to
          the application of equitable principles in any proceeding, legal or
          equitable.

     (4)  The execution and delivery of this Agreement, the consummation by
          Seller of the transactions contemplated herein and compliance by
          Seller with the terms and provisions hereof do not and will not
          contravene any law applicable to Seller, or result in any breach of or
          constitute any default under any indenture, mortgage, chattel
          mortgage, deed of trust, conditional sales contract, bank loan or
          credit agreement, or other agreement or instrument to which Seller is

          affected.

     (5)  On the Delivery Date, Seller shall have and convey to Purchaser good

          or other encumbrances of any kind or nature whatsoever.

     (6)  To the best of Seller's knowledge, none of the Equipment has been
          subjected to extreme heat or stress (including, without limitation,
          such as would result from an accident or fire) and none of the
          Equipment has had an uncontained failure.

     B.  Purchaser hereby represents and warrants to Seller that:


                                      -5-
<PAGE>
 
     (1)  Purchaser is a corporation duly organized, validly existing and in
          good standing under the laws of the State of Delaware, and has the

          delivery and performance by Purchaser of this Agreement.

     (3)  This Agreement has been duly authorized, executed and delivered by
          Purchaser and is a valid, enforceable and binding obligation of
          Purchaser, except as such enforceability may be limited by applicable
          bankruptcy, insolvency, moratorium or similar laws affecting the
          rights of creditors generally, and except as enforceability may be
          subject to the application of equitable principles in any proceeding,
          legal or equitable.

     (4)  The execution and delivery of this Agreement, the consummation by
          Purchaser of the transactions contemplated herein and compliance by
          Purchaser with the terms and provisions hereof do not and will not
          contravene any law applicable to Purchaser, or result in any breach of
          or constitute any default under any indenture, mortgage, chattel
          mortgage, deed of trust, conditional sales contract, bank loan or
          credit agreement, or other agreement or instrument to which Purchaser
          is a party or by which Purchaser or its properties or assets may be
          bound or affected.

7.   TAXES AND INDEMNIFICATION

     A.  Purchaser and Seller shall cooperate and use reasonable efforts to
minimize or avoid the imposition of any sales or other taxes on the sale,
delivery and transfer of title to the Equipment.  Notwithstanding the foregoing,
Seller agrees to pay promptly when due, and will indemnify and hold Purchaser
harmless from any and all fees (including, without limitation, license,
registration and recording fees and assessments), taxes (including, without
limitation, gross receipts, income, sales, rental, use, turnover, value added,
property (tangible or intangible), excise and stamp taxes), levies, imposts,
duties, charges, assessments or withholdings of any nature whatsoever, together
with any and all penalties, fines, additions to tax and interest thereon or
computed by reference thereto (except taxes levied or assessed against Purchaser
based upon gross receipts or net income or taxes imposed upon Purchaser for the
privilege of doing business or exercising a franchise) arising out of the sale,
purchase and delivery of the Equipment, in any manner levied, assessed or
imposed by any government or subdivision or agency thereof having jurisdiction.

     B.  Purchaser hereby agrees to indemnify, protect, save and keep harmless
Seller and Seller's officers, directors, employees, agents, affiliates,
successors and assigns (each, an "Indemnitee") from and against, and on written
demand to pay, or to reimburse each Indemnitee for the payment of, any and all
liabilities, obligations, losses, damages, penalties, claims (including, without
limitation, claims arising out of negligence or involving strict liability in
tort), suits, actions, costs, expenses and disbursements (including, without
limitation, reasonable legal fees, costs and related expenses), of whatsoever
kind and nature ("Expenses") imposed on, incurred by or asserted against any
Indemnitee after the Delivery Date relating to or arising directly or indirectly
out of or in any way connected with the ownership, possession, control, use,
operation, sale, leasing or other application or disposition of the Equipment or
any part thereof or interest therein after the Delivery Date, whether by
Purchaser, Purchaser's customer or any other person; provided, however, that
such 

                                      -6-
<PAGE>
 
Expenses are not judicially determined to have been attributable to such
Indemnitee's gross negligence or willful misconduct or the breach by Seller of
any express warranty, representation or obligation of Seller hereunder. The
obligations contained in this Article 7B. shall survive the sale and delivery of
the Equipment hereunder and are expressly made for the benefit of, and shall be
enforceable by, Seller and each other Indemnitee entitled thereto.

8.   NOTICES

overhaul or testing thereon.  Seller agrees to execute such documents as may be
reasonably necessary to evidence the assignment hereby made or contemplated.

11.  LOSS OR DAMAGE PRIOR TO DELIVERY

     A.  In the event of damage to any of the Equipment following the execution
hereof and prior to the Delivery Date, Purchaser shall have the right to delay
the Delivery Date for a reasonable period of time (but not beyond March 31,
1999, or such later date as is mutually agreed) to ensure to Purchaser's
satisfaction that the Equipment will be repaired and restored to the condition
required by this Agreement; and if such damage delays delivery of any of the
Equipment beyond March 31, 1999 (or such later date as is mutually agreed),
Purchaser or Seller shall have the right to terminate this Agreement by giving
written notice to the other, and upon such termination all rights and
obligations of both parties hereunder shall be discharged automatically without
further act or deed.

     B.  In the event of total loss or destruction of any of the Equipment
following the execution hereof and prior to the Delivery Date, either Purchaser

accordance with the laws of the State of New York, United States of America,

13.  MISCELLANEOUS

     A.  All warranties and representations made by either party shall survive

required in connection herewith and the transactions contemplated hereby.

     C.  This Agreement is a confidential document between Purchaser and Seller

     F.  The rights of the parties hereunder are cumulative, not exclusive, may
be exercised as often as each party considers appropriate and are in addition to
its rights under general law.  The rights of one party against the other party
shall not be deemed waived or amended except by an express waiver or amendment

any other or further exercise of that or any other such right; and no act or
course of conduct or negotiation on a party's part or on its behalf will in any
way preclude such party from exercising any such right or constitute a
suspension or any amendment of any such right.

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof or rendering unenforceable such provision in any other
jurisdiction.  To the extent permitted by applicable law, Seller and Purchaser
hereby waive any provision of law which renders any provision hereof prohibited
or unenforceable in any respect.

delivering an executed counterpart of this Agreement by facsimile will also
deliver an originally executed counterpart; provided the failure of any party to

                                PROMISSORY NOTE

U.S.$9,137,500                                                  March 24, 1999

        FOR VALUE RECEIVED, TOWER AIR, INC., a Delaware corporation (the
"Borrower"), by this promissory note (the "Note") irrevocably and
unconditionally promises to pay to the order of UNICAPITAL CORPORATION, a
Delaware corporation, or any assignee of this Note or any successor or assignee
thereof (the "Holder"), the principal sum of NINE MILLION ONE HUNDRED THIRTY
SEVEN THOUSAND FIVE HUNDRED DOLLARS (US$9,137,500) payable in eighteen (18)
consecutive equal monthly installments of principal and interest due on the same
day of each month of each year until maturity beginning on April 23, 1999;
provided, however, that the final installment of principal and interest payable
hereunder shall be in the amount of all of the remaining and then outstanding
principal balance of this Note, together with interest accrued thereon.

        The unpaid principal amount from time to time outstanding shall bear
interest from the date of this Note at the fixed rate of interest of ten percent
(10%) per annum. Any principal, interest or any other amount hereunder which is
not paid when due (whether as stated, by acceleration or otherwise) shall, to
the full extent permitted by law, thereafter bear interest at the rate of twelve
percent (12%) per annum from the date such amount shall have become due and
payable up to the date the same shall be paid. Interest shall be computed on the
basis of a 360 day year consisting of 12 months of 30 days each. Anything in
this Note to the contrary notwithstanding, the Holder shall not be permitted to
charge or receive, and the Borrower shall not be obligated to pay, interest in
excess of the maximum rate from time to time permitted by applicable law.

        All payments to be made hereunder by the Borrower shall be made without 
set-off, deduction, counterclaim or withholding whatsoever, in United States
dollars in same day funds not later than 3:00 p.m., New York time, on the due
date, by wire transfer of immediately available funds to NationsBank, N.A., ABA
No. 111000012, Account No. 3751028367, For Final Credit To: UniCapital
Corporation, or to such other account as the Holder may from time to time
designate, in writing, to the Borrower. Whenever any payment hereunder shall be
stated to be due on a day that is not a Working Day, such payment shall be made
on, and interest shall be payable to, the succeeding Working Day unless the
succeeding Working Day shall fall in the succeeding calendar month, in which
event such payment shall be made on the preceding Working Day. "Working Day"
shall mean a day on which dealings in currencies and exchange between banks may
be carried on in New York, New York.

        The Borrower agrees to indemnify the Holder for, and hold the Holder
harmless from, any present or future claim or liability for any registration
charge or any stamp, excise or other similar taxes and any penalties or interest
with respect thereto, which may be imposed by any jurisdiction in connection
with this Note or enforcement hereof.

<PAGE>
 
        The Borrower hereby represents and warrants that: (a) the Borrower is a
corporation duly organized, validly existing and in good standing under the laws
of Delaware and has full power, authority and legal right to execute, deliver
and perform this Note, and has taken all necessary corporate and other action to
authorize the execution, delivery and performance of this Note on the terms and
conditions hereof; (b) this Note constitutes the legal, valid and binding
obligation of the Borrower enforceable in accordance with its terms, except as
such enforceability may be limited by applicable bankruptcy, insolvency,
moratorium or similar laws affecting the rights of creditors generally, and
except as enforceability may be subject to the application of equitable
principles in any proceeding, legal or equitable; (c) the execution, delivery
and performance by the Borrower of this Note will not violate the charter,
bylaws or other corporate rules of the Borrower or any provision of law or
regulation or of any judgment, order or decree of any court, arbitrator or
governmental authority or of any agreement of any nature whatsoever, binding
upon the Borrower or its assets; (d) no consent or exemption is required in
connection with the execution, delivery, performance (including payment as
specified in the fourth paragraph of this Note), validity or enforceability of
this Note; (e) no Event of Default (as defined herein) has occurred and is
continuing; (f) the obligations of the Borrower under this Note rank at least
pari passu (in priority of payment, security and otherwise) with all other
unsecured pecuniary obligations of whatsoever nature (including contingent
obligations) of the Borrower outstanding as of the date hereof; (g) except as
set forth on the schedule provided to UniCapital Aircraft Engine Group, Inc.
(formerly United States Turbine Engine Corporation), a wholly owned subsidiary
of the Holder, on December 28, 1998, no litigation, arbitration or
administrative proceeding of or before any court, arbitrator or governmental
authority is pending or, to the knowledge of the Borrower, threatened (i) with
respect to any aspect of this Note or (ii) affecting the Borrower or any of its
assets, which, if adversely determined, would have a material adverse effect on
the business, prospects or financial condition of the Borrower; (h) all tax
returns required to be filed by the Borrower have been filed and all taxes
payable by the Borrower have been paid, except those being contested in good
faith by appropriate proceedings for which adequate reserves have been provided
on its books; and (i) this Note is issued to evidence the financing of 85% of
the Purchase Price (as defined in that certain Engine Purchase Agreement dated
as of February 8, 1999, between the Borrower and UniCapital Aircraft Engine
Group, Inc., a wholly owned subsidiary of the Holder).

        If any of the following events (each, an "Event of Default") occurs: (a)
the Borrower fails to pay when due any principal of or interest on this Note or
any other amount payable hereunder and such failure is not remedied within 3
Working Days; or (b) the Borrower fails to make any payment when due on any
pecuniary obligation(s) (other than this Note) of any nature whatsoever
(including, without limitation, contingent obligations), (x) owed to UniCapital
Corporation or an affiliate of UniCapital Corporation or (y) which pecuniary
obligation(s) exceed US$5,000,000 (or the equivalent in one or more other
currencies) individually or in the aggregate, or defaults in performance of any
agreement under which any such obligation is created, or any other event shall
occur or condition exist, if the effect of such default or other event or
condition is to cause such obligation to become, or to permit holders of such
obligation, or a trustee on their behalf, to declare such obligation, due prior
to its normal maturity, provided, however, that if the Borrower is contesting in
good faith the amount of any such obligation and has set aside adequate
reserves, such failure to pay shall not be deemed to constitute an Event of


                                     -2-

<PAGE>
 
Default hereunder during the pendency of such contest; or (c) the Borrower
becomes insolvent or unable to pay its debts as they mature, or consents to the
appointment of a custodian, trustee, intervenor or receiver for it or a
substantial part of its property, or any such custodian, trustee, intervenor or
receiver is appointed, or bankruptcy, dissolution, reorganization, intervention,
arrangement or liquidation proceedings (or proceedings similar in purpose or
effect) are instituted (i) by the Borrower or (ii) against the Borrower and are
not dismissed within sixty (60) days; or (d) any governmental consent or
exemption necessary to enable the Borrower to comply with or perform its
obligations under this Note is revoked, withdrawn or withheld, or otherwise
fails to be issued or remain in full force and effect; or (e) a warrant of
attachment or execution or similar process against any substantial part of the
assets of the Borrower is issued; or (f) any representation or warranty made by
the Borrower in this Note proves to have been incorrect when made; or (g) there
occurs a material adverse change in the business, prospects or financial
condition of the Borrower; or (h) the Borrower fails to perform or observe any
covenant or other term contained in this Note and such failure, if capable of
remedy, is not remedied within 15 days after its receipt of written notice of
such failure to perform or observe from the Holder; then, and in any such event,
the Holder may, by notice of default given to the Borrower, declare unpaid
principal, accrued interest and all other amounts payable under this Note to be
immediately due and payable without presentment, demand, protest or other notice
of any kind, each of which is hereby expressly waived by the Borrower. The
Borrower hereby agrees that, so long as any principal, interest or any other
amount remains outstanding and unpaid under this Note, the Borrower shall notify
the Holder promptly by telephone, confirmed in writing, or in writing, upon the
occurrence of any Event of Default.

of or interest on this Note or (ii) the making of any payment or prepayment
hereunder on a day or in an amount other than the dates and amounts specified in
this Note.

        No action or omission by the Holder shall constitute a waiver of any
rights or remedies of the Holder hereunder. Such rights and remedies are
cumulative and not exclusive of any rights or remedies provided by law. Payment
of principal of and interest on this Note shall not discharge the Borrower's
obligation with respect to any other amount payable hereunder. In connection
with any assignment by the Holder of this Note and the loan evidenced hereby,
the Borrower hereby agrees promptly to execute and deliver such documents and
instruments, and to take such further action as may be reasonably requested by
the Holder or such assignee to further evidence, or in connection with, such
assignment, including, without limitation, the giving by the Borrower of any
notice to any regulatory authority or others deemed necessary or advisable by
the Holder or such assignee in its sole discretion. The Holder shall have all

     disbursed, and (ii) in no event shall LESSEE be entitled to reimbursement
     for any expenses related to removal or installation of an Engine for
     maintenance or any other shipping or transportation expenses.  To the

          (e) Late Payments.  As to any (i) amount due under this Lease that is

by LESSEE as herein provided and not so paid by LESSEE, LESSEE shall pay to
LESSOR at the time of payment thereof, as Supplemental Rent, interest thereon at
the Post-Default Rate, from either the due date thereof (as to amounts referred
to in clause (i)) or the date of the advance by LESSOR (as to amounts referred
to in clause (ii)), as the case may be, to the date such late payment is paid in

              ----------------------------
contrary herein, LESSEE's obligations and liabilities to pay all amounts payable

circumstance, including, without limitation, (i) any setoff, counterclaim,
recoupment, defense or other right that LESSEE may have against LESSOR or any
other Person for any reason whatsoever, (ii) any defect in the title,
airworthiness, condition, design, operation or fitness for use of or any damage
to or loss or destruction of, an Engine or any Part thereof or any interruption
or cessation in the use or possession of any Part thereof by LESSEE for any
reason whatsoever, (iii) any insolvency, bankruptcy, reorganization or similar
proceedings by or against LESSEE or any other Person, (iv) the disaffirmance or
rejection of this Lease by LESSOR or any trustee in bankruptcy (or similar
party) for LESSOR, (v) claims against the Manufacturer or manufacturers of an
Engine or any Part or component thereof, (vi) enforceability or lack of
enforceability of any of the terms or conditions of this Lease, (vii) breach by
LESSOR of any warranty, express or implied, with regard to an Engine or any Part
thereof, including, without limitation, merchantability or fitness for any
purpose or use relating to or otherwise made or alleged to be made by LESSOR to
LESSEE or any of its agents, representatives or employees with regard to an
Engine or any Part thereof, (viii) any right, claim, demand, bill, action or
suit whatsoever by or against or on the part of LESSEE against LESSOR,
including, without limitation, whether arising out of legal action or otherwise
(x) at law or in equity, (y) whether affirmative, negative or defensive in
nature for or on account of the legality, enforceability, validity or other
infirmity as to (A) any of the terms or conditions of this Lease, (B) any
express or implied warranty as to an Engine or any Part thereof or (C) arising
out of or as a result of any contract, agreement, assignment or transaction
between LESSOR and LESSEE whether direct or indirect, written or oral, or (ix)

terminating this Lease, it being the intention of the LESSOR and LESSEE that all
Rent and other amounts payable by LESSEE hereunder shall be payable in all
events unless the obligation to pay the same shall be terminated pursuant to the
express provisions of this Lease. LESSEE hereby waives, to the fullest extent
permitted by applicable law any and all rights it may now have or that at any
time hereafter may be conferred upon it, by statute or otherwise, to terminate,
cancel, quit or surrender this Lease except in accordance with the express terms
hereof. Each payment of Rent made by LESSEE shall be final as to LESSOR and
LESSEE, and LESSEE will not seek to recover all or any part of any such payment
of Rent from LESSOR or its successors or assigns for any reason whatsoever.
Nothing in this Section 3(f) shall be construed to limit LESSEE's right to seek
a recovery of any payment of Rent or any other amount which is not due and
payable hereunder, or to limit LESSEE's rights and remedies to pursue, in a
court of law or otherwise, any claim it may have against LESSOR on account of
any failure of LESSOR to perform its obligations hereunder or in connection
herewith.

     upon not less than thirty (30) days' prior irrevocable written notice to
     the other, to declare the Purchase Option to be deemed exercised by LESSEE.
     Upon any exercise or deemed exercise by LESSEE of the Purchase Option, on
     the Option Exercise Date specified in LESSEE's notice of exercise or on the
     Option Exercise Date on which the Purchase Option is deemed to have been
     exercised, as the case may be, (i) LESSEE shall acquire the Engines from
     LESSOR by paying, as the purchase price therefor, the Option Price of the
     Engines as of the Option Exercise Date (as set forth on Schedule 3 hereto),
     less the Option Amount, plus any Rent then due and unpaid under this Lease
     (including any payment of Basic Rent due on the Option Exercise Date) and
     (ii) LESSOR shall transfer to LESSEE all of LESSOR's right, title and
     interest in and to the Engines, "as is, where is" and without recourse or
     warranty (except as to title to the Engines and the absence of LESSOR's
     Liens thereon) and shall execute and deliver to LESSEE a Bill of Sale in
     the form attached hereto as Exhibit D and such other documents or
                                 ---------                            
     instruments as LESSEE shall reasonable request to evidence (on the public
     record or otherwise) such transfer.  Upon the sale of the Engines as
     contemplated by this Section 3(g), the obligation of LESSEE to pay Rent
     shall cease and the Term shall end, effective as of the date of such sale.

               (ii) Upon any exercise or deemed exercise by LESSEE of the
     Purchase Option, all obligations of the LESSOR to make disbursements to
     LESSEE from the Maintenance Reserves, including without limitation pursuant
     to any request for reimbursement made by LESSEE prior to the date of
     LESSEE's exercise or deemed exercise of the Purchase Option shall terminate
     as of the applicable Option Exercise Date; and any portion of the
     Maintenance Reserves or Security Deposit not applied toward the payment of
     the Option Price of the Engines as of the applicable Option Exercise Date
     shall be applied first, so much of such amounts as shall be required to

                   ----------------
Deposit pursuant to Section 8(a) or Section 8(b) hereof shall be held by LESSOR
                    ------------    ------------
during the Term as security for the full and punctual performance by LESSEE of
all of its obligations hereunder. During the Term, the Security Deposit shall be
for LESSOR's sole and exclusive use and may be commingled by LESSOR with other
funds. LESSOR may, but shall not be obligated to, apply the Security Deposit, in
whole or in part for the payment of any Rent and any other amount owing from
time to time by LESSEE hereunder, or utilize the Security Deposit in whole or in
part to perform any of LESSEE's obligations hereunder or otherwise remedy any
Default, without prejudice to any other remedy of LESSOR. LESSEE shall not
attempt to subject the Security Deposit to any Lien or to assign any interest
therein to any Person. LESSOR shall be entitled to the remedy of offset against
and application of the Security Deposit, without any prior notice to or demand
against LESSEE (except to the extent otherwise required by applicable law), all
of which are hereby waived. If LESSOR uses or applies all or a portion of the
Security Deposit, such application shall not be deemed a cure of any Default,
and LESSEE shall, within three (3) Business Days after LESSOR's demand therefor,
deposit with LESSOR in immediately available funds an amount sufficient to
restore the Security Deposit to its total amount immediately prior to such
application. Within fifteen (15) Business Days after redelivery of the Engines
to LESSOR by LESSEE in conformity with the provisions of Section 10 hereof, and
                                                         ----------
provided LESSEE has paid in full of all amounts owing by LESSEE hereunder and
performed all of its obligations hereunder, LESSOR will return to LESSEE the
Security Deposit, less any amounts applied by LESSOR and not replenished by
LESSEE. Any amounts held by LESSOR as a Security Deposit shall bear simple
interest at a rate equal to ten percent (10%) per annum. All interest accrued in
respect of the Security Deposit shall be kept and held by LESSOR as additional
security hereunder and, subject to the same conditions of return as if it had
been part of the Security Deposit.

replacement Part when incorporated or installed in or attached to any Engine in
accordance with Section 6(b) may be owned by a financially and operationally
                ------------
responsible air carrier subject to such a normal pooling arrangement; provided
that LESSEE, at its expense as promptly thereafter as possible, either (i)

                                                        ------
amount required to be paid by LESSEE pursuant to Section 8(a), which amount
                                                 ------------
shall be applied in reduction of LESSEE's obligation to pay such amount if not
already paid by LESSEE or, to the extent such amount has been paid by LESSEE, to
LESSEE to reimburse LESSEE for its payment thereof and (iii) third, to LESSEE
                                                             -----
the balance, if any, of such payment. The insurance payments with respect to any
property damage or loss not constituting an Event of Loss with respect to an
Engine will be paid to LESSEE and applied by LESSEE in payment for repairs to or
replacement of property in accordance with the terms of Section 6(c) against
                                                        ------------
evidence satisfactory to LESSOR that such repairs and replacement have been
made, or, 




                                     -16-
<PAGE>
 
if such repairs or replacement have already been paid for by LESSEE, to
reimburse LESSEE therefor, and any balance remaining after compliance with such
Section with respect to such loss shall be paid to LESSOR.

          (e) Reports.  On or before the Delivery Date, LESSEE will furnish or
              -------
cause to be furnished to LESSOR a report signed by a firm of independent
aircraft insurance brokers, stating the opinion of such firm that the insurance
then carried and maintained on the Engines complies with the terms hereof.
LESSEE will cause such firm to advise LESSOR and each other Additional Insured
in writing promptly of any default in the payment of any premium, of any other
act or omission on the part of LESSEE of which such firm has knowledge that
might invalidate or render unenforceable, in whole or in part, any insurance on
the Engines and of each claim made by LESSEE in respect of the Engines. Prior to
the expiration or on or prior to the termination date of any insurance required
hereunder, LESSEE will provide LESSOR with telex or fax confirmation from
LESSEE's insurance brokers of that certificate of insurance evidencing the
replacement of such insurance will be issued on the termination date of the
prior certificate. Within seven (7) days after such renewal, LESSEE will furnish
its brokers' certificates of insurance to LESSOR.

          (f) Failure to Insure.  In the event that LESSEE shall fail to
              -----------------
maintain or cause to be maintained insurance as herein provided, LESSOR may, at
its option, but without liability to LESSEE for failure to do so, provide such
insurance and, in such event, LESSEE shall, upon written demand, reimburse
LESSOR for the cost thereof as Supplemental Rent.

          (g) Additional Insurance.  Nothing contained in this Lease shall
              --------------------
prevent LESSOR or LESSEE, each at its own expense and for its exclusive benefit,
from carrying insurance covering the Engines in addition to the insurance
required under this Section 9; provided, that no such additional insurance shall
prejudice the insurances required hereunder or the recovery by LESSEE or LESSOR
thereunder. The insurance payments for any property damage loss covered by any
such additional insurance shall be paid directly to the party carrying such
insurance.

          (h)  Continuation of Liability Insurance.  If LESSEE exercises the
               -----------------------------------                            
Purchase Option and purchases the Engines, then LESSEE shall continue to cause
the Indemnitees to be named as additional insureds under LESSEE's or the Engines
operators' aviation and airline general third party liability insurance for a
period of two (2) years after the Option Exercise Date (with respect to claims
arising as a result of LESSEE's use or operation of the Engines during the
Term).

     10.  Return of Engine.    The provisions of this Section 10 shall apply to
          ----------------                            ----------               
any return of the Engines to LESSOR upon termination of this Lease (including,
without limitation, such return resulting from an Event of Default); provided,
that if this Lease is terminated pursuant to Section 14, any action that is
                                             ----------                    
required to be taken by Lessee prior to the return of the Engines shall be taken
immediately after the return of the Engines.

          (a)  Redelivery upon Termination.  On the date of termination of
               ---------------------------                                  
this Lease, LESSEE shall at its own expense return the Engines to LESSOR in
Norwalk, Connecticut.  At 

                                     -17-
<PAGE>
 
the time of return of each Engine to LESSOR, LESSOR and LESSEE shall execute a
Return Acceptance Receipt in substantially the form of Exhibit B hereto. Upon
                                                       ---------
delivery to Lessor:

               (i) All outstanding airworthiness directives, mandatory service
     bulletins and instructions issued by the FAA affecting the Engines and
     requiring compliance (either by means of repetitive inspections,
     modifications or terminating action) prior to the return date of the Engine
     to LESSOR shall have been complied with on a terminating action basis (if
     terminating action is available).  In the event LESSEE has obtained a
     waiver, deviation, dispensation or extension from the FAA and/or any other
     aviation authority from having to comply with any such mandatory orders,
     directives and instructions, LESSEE shall, irrespective of such waiver,
     deviation, dispensation or extension comply on a terminating action basis
     with all such mandatory orders, directives and instructions covered by such
     waiver, deviation, dispensation or extension prior to return of the Engines
     to LESSOR;

               (ii) All outstanding deferred maintenance items shall have been
     cleared on a terminating action basis; and

               (iii)  No special or unique Manufacturer or FAA inspection or

     aircraft or engines of their types) and which shall have arisen during the
     Term hereof will exist with respect to any Engine and its parts, components
     and systems.

          (b)  Condition of Engine.  At the time of redelivery, the Engines
               -------------------                                           
shall meet the following conditions:

               (i) Each Engine shall be free and clear of all encumbrances and
     liens other than Lessor Liens;

               (ii) Each Engine shall have a full (compressor and turbine
     section) video borescope inspection and a full performance test cell run
     performed by LESSEE at the time of LESSOR's ground inspection provided for
     in Section 7(f), and satisfactory evidence shall be provided to LESSOR
        ------------                                                       
     reflecting the correction of any discrepancies found during such
     inspection;

               (iii)  Each Engine shall have affixed to it a current serviceable
     tag pursuant to U.S. FAA requirements;

               (iv) Prior to returning the Engines to LESSOR F.O.B. Norwalk,

     and plugging all openings of the Engine; (ii) preserving the Engine for
     ninety (90) days or more storage; (iii) completely covering the Engine; and
     (iv) otherwise preparing the Engine for shipment in accordance with the
     Manufacturer's specifications/recommendations.  Any trucks used for
     shipment of an Engine will be equipped with air ride or air cushion
     trailers.  On any given shipment, such truck will be dedicated to Engines
     belonging solely to LESSOR; except that additional items may be transported
     on the truck, provided that 



                                     -18-
<PAGE>
 
     (a) the Engines may be off-loaded at the redelivery location without
     disturbing any of the additional items and (b) LESSOR will not handle or
     reposition any of the additional items on the truck; and

               (v) If the Engine is a JT9D that has been operated during the
     Term and is subject to the requirements of AD #86-11-04 (Diffuser Case Rear
     Rail Inspection, SB 5591-R4, as amended), LESSEE will return such Engine
     with at least fifty (50) cycles remaining until the next Diffuser Case Rear
     Rail Inspection.

          (c)  Engine Documentation.  LESSEE shall return to LESSOR at the
               --------------------                                         
time the Engines are returned to LESSOR, all of the Engine records documents,
manuals and data provided to LESSEE by LESSOR prior to, on or after the Delivery
Date, updated and maintained by LESSEE through the date of return of the
Engines.  In addition, LESSEE shall also provide LESSOR at the time the Engines
are returned to LESSOR with all records, documents, manuals, authorizations,
drawings and data, in each case in the English language, that were developed or
caused to be developed by LESSEE and/or required by the appropriate governmental
agency having jurisdiction updated and maintained by LESSEE for the Engines

already owned by LESSOR, when delivered to LESSOR pursuant to this Section
                                                                   -------
10(c), shall thereupon become the property of LESSOR.

          (d)  Service Bulletin Kits.  All vendor and manufacturer's service
               ---------------------                                          
bulletin kits ordered and received by LESSEE for any Engine but not installed
therein shall be returned with the Engines.  Title to such kits shall pass to
LESSOR concurrently with the delivery of the Engines to LESSOR.

     11.  Representations and Warranties of LESSEE.  LESSEE represents and 
          ----------------------------------------
warrants to LESSOR as follows:

          (a) LESSEE (i) has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware, (ii) has
full corporate power and authority and legal right to own its properties and to
carry on its business as presently conducted and to perform its obligations
under this Lease, (iii) is the holder of an air carrier certificate duly issued
pursuant to the Federal Aviation Act and such certificate is in full force and
effect, and (iv) holds all material licenses, certificates and permits from all
Government Entities of the United States and other jurisdictions necessary for
the conduct of its business as now conducted and for the operation of the
Engines.

          (b) The execution, delivery and performance of this Lease and each
Lease Supplement has been duly authorized by all necessary corporate action of
LESSEE, and does not and will not (i) result in the violation of the provisions
of the charter documents or bylaws of LESSEE as in effect on the date hereof,
(ii) require stockholder approval or approval or consent of any trustee or
holders of any indebtedness of LESSEE, except such approvals which have been
obtained and are in full force and effect, (iii) contravene any law, rule or
regulation or any order of any Government Entity binding on Lessee, and (iv)
conflict with or result in a breach of any terms or provisions of or constitute
a default under, or result in or require the creation or 



                                     -19-
<PAGE>
 
imposition of any Lien upon any material property or assets of LESSEE under, any
material indenture, mortgage or other agreement or instrument as in effect on
the date hereof to which LESSEE is a party or by which it or any of its property
is bound, or any applicable law, rule or regulation, judgment, order or decree
of any Government Entity or court having jurisdiction over LESSEE or any of its
properties.

          (c) This Lease and each Lease Supplement constitutes the legal, valid
and binding obligation of LESSEE, enforceable against LESSEE in accordance with
its terms except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally and, to the extent that certain remedies require or may require
enforcement by a court of equity, by such principles of equity (regardless of
whether such enforceability is considered in a proceeding at law or in equity)
as a court having jurisdiction may impose.

          (d) There are no suits or proceedings pending or, to LESSEE's
knowledge, threatened in any court or before any Government Entity against or
affecting LESSEE that would, if adversely determined, (i) prevent or adversely
affect LESSEE's ability to perform its obligations under this Lease or (ii)
materially adversely affect the financial condition or operations of LESSEE and
its consolidated subsidiaries, taken as a whole, except as otherwise set forth
on the schedule provided to LESSOR on December 28, 1998.

          (e) The chief executive office (as such term is used in Article 9 of
the Uniform Commercial Code) of LESSEE and the office where LESSEE will keep its
corporate records concerning the Engine is located in the State of New York.
Lessee will notify Lessor thirty (30) days in advance of moving either such
office to another location.

          (f) LESSEE has not retained or employed any broker, finder or
financial advisor to act on its behalf in connection with its lease of the
Engines and has not authorized any broker, finder or financial advisor retained
or employed by any other person so to act.

          (g) There is no Tax, levy, impost, deduction, charge or withholding
imposed by the State of New York or any Taxing Authority thereof or therein
either (i) on or by virtue of the execution or delivery of this Lease or (ii) on
any payment made or to be made by LESSEE under this Lease.

          (h) The obligations of LESSEE under this Lease rank at least pari
passu in right of payment with all other unsecured obligations of LESSEE, with
the exception of such obligations as are mandatorily preferred by law.

          (i) LESSEE will give notice to LESSOR promptly upon obtaining actual
knowledge of any Default or Event of Default; and

          (j) LESSEE acknowledges that it is the intention of LESSOR that LESSOR
shall be entitled to the benefits of Title 11 U.S.C. (S) 1110 and any similar or
analogous provisions of any successor statute ("Section 1110") with respect to
the Engines and this Lease, and LESSEE shall not oppose any motion, petition or
application filed by LESSOR with any 


                                     -20-
<PAGE>
 
bankruptcy court having jurisdiction over LESSEE whereby LESSOR seeks recovery
of possession of the Engines under Section 1110 unless LESSEE shall have
complied with the requirements of Section 1110 to be fulfilled in order to
entitle LESSEE to continue use and possession of the Engines hereunder.

          (k) Without having obtained the prior written consent of LESSOR,
LESSEE will not consolidate with or merge into, or sell or lease in one
transaction or a series of transactions all or substantially all of its assets
to, another corporation or other entity unless such other corporation or entity
is engaged in the airline business, the net worth of the corporation resulting
from such merger or consolidation or corporation or other entity to which such
sale or lease is made would be at least equal to the net worth of LESSEE at the
date hereof, such corporation or other entity assumes all of LESSEE's
obligations under this Lease in a manner and by documents and agreements
satisfactory to LESSOR in its sole discretion, such corporation or other entity
immediately subsequent to such merger, consolidation, lease or sale is not in
default hereunder and if LESSOR receives an opinion satisfactory to it, of
counsel satisfactory to it, as to such assumption and documentation.

     12.  Indemnification.
          ---------------   

          (a)  General Indemnity and Expenses.  LESSEE hereby assumes
               ------------------------------                          
liability for, and hereby agrees to, indemnify, protect, save and keep harmless
LESSOR and its agents, officers, directors, employees, successors and permitted
assigns (each of the foregoing and their respective agents, officers, directors,
employees, successors and assigns being hereinafter referred to as an
"Indemnitee" and any reference herein to an Indemnitee shall include its
- -----------                                                             
respective agents, officers, directors, employees, successors and permitted
assigns) from and against, and on written demand to pay, or to reimburse each
Indemnitee for the payment of, as the case may be, any and all liabilities,
obligations, losses, damages, penalties, claims, suits, actions, costs, expenses
and disbursements, including without limitation legal fees and expenses, of
whatsoever kind and nature (collectively, "Expenses") imposed on, incurred by or
                                           --------                             
asserted against any Indemnitee relating to or arising out of (A) this Lease,
any payments made pursuant hereto or the exercise of rights or remedies
hereunder, (B) the Engines and any Part thereof, whether or not arising out of
the ownership, design, fitness for use, merchantability, airworthiness,
delivery, nondelivery, sublease, presence, storage, modification, replacement,
alteration, maintenance, inspection, repair, possession, repossession after an
Event of Default, use, operation, condition, return, exportation, importation,
transfer or other application or disposition thereof (including, in each case
and without limitation, latent or other defects, whether or not discoverable),
any claim for patent, trademark or copyright infringement, any claim based on
strict or absolute liability, statutory liability or tort and any liability for
any injury to or death of any person or loss of or damage to any property and
(C) any breach of, noncompliance with or misrepresentation made or deemed made
in, under or in connection with this Lease; provided, that LESSEE shall not be
required to indemnify any Indemnitee for: (1) Expenses which would not have
occurred but for the gross negligence or willful misconduct of such Indemnitee;
(2) Expenses which would not have occurred but for the existence of a Lien which
LESSEE is not responsible for discharging under this Lease; or (3) Expenses
arising from 



                                     -21-
<PAGE>
 
the transfer (other than in connection with an Event of Default or Event of
Loss) of any interest in the Engines or the Lease by LESSOR.

     Any payment or indemnity pursuant to this Section 12(a) shall include the
                                               -------------                  
amount, if any, necessary to hold each Indemnitee harmless on a net after-tax
basis from all Taxes required to be paid by such recipient with respect to such
payment or indemnity under laws, rules or regulations of any Government Entity
or Taxing Authority.  If any Indemnitee is entitled to a permanent tax benefit
(whether by way of deduction, credit or otherwise) not taken into account
pursuant to the preceding sentence as a result of the matter indemnified against
under this Section 12(a), such Indemnitee shall promptly pay to LESSEE, after
           -------------                                                     
such permanent tax benefit is realized but not before LESSEE shall have made all
payments theretofore due to such Indemnitee under this Agreement and any other
agreement in respect of the Engines, an amount that, after subtraction of any
further tax savings to which such Indemnitee is entitled as a result of the
payment thereof, is equal to the amount of such permanent tax benefit; provided,
however, that such Indemnitee shall not be obligated to make any payment to
LESSEE pursuant to this sentence so long as a Default or Event of Default shall
have occurred and be continuing or any Rent then due and owing shall not have
been paid.

     If any Indemnitee shall have knowledge of any claim or liability required
to be indemnified against under this Section 12(a), such Indemnitee shall give
                                     -------------                            
reasonably prompt written notice thereof to LESSEE, but the failure of such
Indemnitee so to notify LESSEE shall not relieve LESSEE from any liability that
it would otherwise have to such Indemnitee hereunder except to the extent that
LESSEE's rights respecting any defense thereto are irrevocably and materially
impaired directly and solely as a result of such failure.  LESSEE shall be
obligated to each Indemnitee under this Section 12(a) irrespective of whether
                                        -------------                        
any Indemnitee shall also be indemnified with respect to the same matter under
any other agreement, and each Indemnitee may proceed directly against LESSEE
under this Section 12(a) without first resorting to any such other rights of
           -------------                                                    
indemnification.  Upon the indefeasible payment in full of any indemnities due
and owing under this Section 12(a), LESSEE shall be subrogated to any right of
                     -------------                                            
the Indemnitee in respect of the matter against which indemnity has been given.

          (b)  General Tax Indemnity.  LESSEE agrees that each payment of Rent
               ---------------------                                            
or any amount payable hereunder shall be free of all withholdings of any nature
whatsoever, and in the event that any withholding is required, LESSEE shall pay
an additional amount of Rent such that after the deduction of all amounts
required to be withheld, the net amount of Rent actually and indefeasibly
received by each Indemnitee or the net amount that is actually received by
LESSOR, as the case may be, will equal the amount of Rent or any such amount
payable hereunder or such other amount, as the case may be, that would be due
absent such withholding.  LESSEE hereby agrees to indemnify and hold harmless
from and against, and on written demand, to pay or reimburse each Indemnitee for
the payment of, as the case may be, any and all Taxes imposed upon or asserted
against any Indemnitee or the Engines or any Part thereof or interest therein,
or this Lease, or the rentals received under this Lease, by any federal, state
or local government or other taxing authority in the United States, in any
territory or possession thereof or by any foreign government or any political
subdivision or taxing authority thereof or therein (the foregoing being referred
to herein individually as a "Taxing Authority" and 
                             ---------------- 


                                     -22-

collectively as "Taxing Authorities") upon or with respect to (i) the delivery,
                 ------------------
transport, insuring, ownership, possession, repossession, operation, use,
presence, condition, maintenance, repair, return, sale, storage, redelivery,
manufacture, subleasing, modification, importation, transfer of title,
exportation or other application or disposition of, or the imposition of any
Lien (other than a LESSOR Lien) on the Engines or any Part thereof or interest
therein, (ii) payments of Basic Rent or Supplemental Rent payable pursuant to
this Lease, (iii) the Engines or any Part thereof or any interest therein or the
applicability of this Lease to the Engines or any Part thereof or any interest
therein or (iv) otherwise with respect to or in connection with the transactions
effected under this Lease. The provisions of this Section 12(b) shall not apply
                                                  -------------
to Taxes which are based upon, or measured by, LESSOR's net income.

          (c)  Calculation of Tax Indemnity Payments.  Any payment that LESSEE
               -------------------------------------                            
is required to make to or for the account of an Indemnitee with respect to any
Tax that is subject to indemnification under Section 12(b) shall include the
                                             -------------                  
amount necessary to hold such Indemnitee harmless on a net after-tax basis from
the net amount of all Taxes required to be paid by such Indemnitee as the result
of such payment pursuant to the laws of any Taxing Authority.  The amounts of
any payments to be made pursuant to Section 12(b) shall be calculated by the
                                    -------------                           
Indemnitee entitled to such payments and such calculation shall be conclusive
and binding on LESSEE, absent manifest error.

          (d)  Reports.  If any report, return or statement is required to be
               -------                                                         
filed with respect to any Tax that is subject to indemnification under Section
                                                                       -------
12(b), LESSEE shall timely file the same, except for any such report, return or
- -----                                                                          
statement that a Indemnitee has notified LESSEE that it intends to file.  LESSEE
shall either file such report, return or statement so as to show the ownership
of the Engines in LESSOR and send a copy of such report, return or statement to
LESSOR or, where LESSEE is not so permitted to file in the name of LESSOR, shall
notify LESSOR of such requirement and cooperate reasonably with LESSOR with
respect thereto.  Each Indemnitee shall promptly forward to LESSEE any notice,
bill or advice received by it concerning any Tax.

          (e)  Payment.  Unless otherwise requested by the appropriate
               -------

demand, shall reimburse the appropriate Indemnitee for the payment of any such
Tax made by such Indemnitee.  Within 30 days after the date of each payment by
LESSEE of any Tax referred to in the preceding sentence, LESSEE shall furnish
the appropriate Indemnitee evidence of payment of such Tax acceptable to such
Indemnitee.  LESSEE shall also cause to be furnished, promptly upon request,
such data as any Indemnitee may reasonably require from LESSEE to enable such
Indemnitee to comply with the requirements of any Taxing Authority in respect of
any Tax referred to in Section 12(b).
                       ------------- 

          (f)  Survival.  The obligations contained in this Section 12 shall
               --------                                     ----------      
survive the termination of this Lease, to the extent they have accrued, or
relate to events that have occurred, on or before the date of such termination;
provided that obligations arising as a result of the occurrence of a Default or
an Event of Default shall in any event, without limiting the foregoing, survive
until payment in full and performance of all obligations owing to each
Indemnitee under 



                                     -23-

the foregoing agreements and all other agreements referred to herein or
contemplated hereby. The obligations of LESSEE in respect of all such
indemnities, obligations, adjustments and payments are expressly made for the

option of such Indemnitee without declaring this Lease to be in default or
taking any other action hereunder.

          (a)  No Assignment by LESSEE.  EXCEPT AS OTHERWISE EXPRESSLY
               -----------------------                                  
PROVIDED HEREIN, LESSEE SHALL NOT ASSIGN OR OTHERWISE TRANSFER IN ANY MANNER ANY
OF ITS RIGHTS OR INTERESTS WITH RESPECT TO THIS LEASE, THE ENGINES OR ANY PART
THEREOF.

          (b)  Assignment by LESSOR.  LESSOR may assign at any time and from
               --------------------                                           
time to time all or any part of its right, title and interest in and to this
Lease or the Engine.  The terms and provisions of this Lease shall be binding
upon and inure to the benefit of LESSOR and its successors and assigns.

     14.  Events of Default; Remedies.
          ---------------------------   

          (a)  Events of Default.  The occurrence of any of the following
               -----------------

                            ----------------                                  
voluntary or involuntary or come about or be effected by operation of law or
pursuant to or in compliance with any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
each such Event of Default shall be deemed to exist and continue so long as it
shall not have been remedied:

               (i) LESSEE shall fail to make any payment of Rent within three
     (3) Business Days after the same shall have become due and payable;

               (ii) LESSEE shall fail to carry and maintain insurance on or with
     respect to the Engines in accordance with Section 9;
                                               --------- 

               (iii)  LESSEE shall fail to perform or observe any other

     fifteen (15) days after written notice thereof to LESSEE;

               (iv) any representation or warranty made by LESSEE herein shall

<PAGE>
 
     of any agreement under which any such obligation is created, or any other
     event shall occur or condition exist, if the effect of such default or
     other event or condition is to cause such obligation to become, or to
     permit holders of such obligation, or a trustee on their behalf, to declare
     such obligation, due prior to its normal maturity, provided, however, that
     if LESSEE is contesting in good faith the amount of any such obligation and
     has set aside adequate reserves, such failure to pay shall not be deemed to
     constitute an Event of Default hereunder during the pendency of such
     contest;

               (vi) LESSEE shall (A) voluntarily commence any proceeding or file
     any petition seeking relief under any applicable bankruptcy, insolvency,

     filed against it in any such proceeding, (E) make a general assignment for

     sixty (60) days or an order or decree approving or ordering any of the
     foregoing shall continue unstayed and in effect for thirty (30) days;

               (viii)  final judgment for the payment of money in excess of
     US$1,000,000 (or the equivalent in another currency) shall be rendered
     against LESSEE and the same shall remain undischarged for a period of ten

     stayed or bonded in a manner satisfactory to LESSOR;

               (ix) possession of any Engine shall be transferred to another

any time thereafter so long as the same shall be continuing, LESSOR may, at its
option, declare this Lease to be in default by notice to LESSEE; and at any time
thereafter, so long as LESSEE shall not have remedied all outstanding Events of
Default before LESSOR shall have commenced to exercise its rights or remedies
hereunder, LESSOR may exercise one or more of the following 


                                     -25-
<PAGE>
 
rights and remedies with respect to the Engines as LESSOR in its sole discretion
shall elect, to the extent permitted by, and subject to compliance with any
mandatory requirements of, applicable law then in effect:

               (i) cause LESSEE, upon the written demand of LESSOR and at
     LESSEE's expense, to return promptly, and LESSEE shall return promptly (and
     in no event later than two days after such demand), the Engines to LESSOR
     or its order in the manner and condition required by, and otherwise in
     accordance with, Section 10 as if the Engines were being returned at the
                      ----------                                             
     end of the Term, or LESSOR, at its option, may enter upon the premises
     where the Engines is located and take immediate possession of and remove
     the same;

               (ii) hold, use, operate, keep idle or lease to others the
     Engines, with or without taking possession thereof as LESSOR in its sole
     discretion may determine, free and clear of any rights of LESSEE and
     without any duty to account to LESSEE with respect to such action or
     inaction or for any proceeds with respect thereto, except that LESSEE's
     obligation to pay Basic Rent for any periods in respect of the Engines
     accruing after LESSEE shall have been deprived of possession of the Engines
     pursuant to this Section 14 shall be reduced by the net proceeds, if any,
                      ----------                                              
     received by LESSOR from leasing the Engines to any Person other than LESSEE
     for the same periods or any portions thereof;

               (iii)  LESSOR may exercise any other right or remedy that may be
     available to it under applicable law or proceed by appropriate court action
     to enforce the terms hereof or to recover damages for the breach or to
     rescind this Lease;

               (iv) LESSOR may terminate this Lease; and/or

               (v) whether or not LESSOR shall have exercised, or shall
     thereafter at any time exercise, any of its rights under clauses (i), (ii),
     (iii) or (iv) above, LESSOR, by written notice to LESSEE specifying a
     payment date not earlier than five (5) Business Days after the date of such
     notice, may terminate this Lease and demand that LESSEE pay to LESSOR and
     LESSEE shall pay to LESSOR, on the payment date specified in such notice,
     as liquidated damages for loss of a bargain and not as a penalty, the sum
     of: (A) any unpaid Basic Rent due for periods ending on or prior to the
     payment date specified in such notice and any unpaid Supplemental Rent due
     on or prior to such payment date, plus (B) in lieu of the Basic Rent due on
     Payment Dates occurring after the Payment Due Date, an amount equal to the
     aggregate unpaid Basic Rent which would otherwise have accrued over the
     remainder of the Term but for the Event of Default.  The amounts specified
     in such notice shall bear interest at the Post-Default Rate from the
     payment date specified in such notice until payment is made.

     In addition, LESSEE shall be liable, for any and all unpaid Basic Rent then
due and Supplemental Rent then due hereunder before or during or after the
exercise of any of the foregoing remedies and for all legal fees and other costs
and expenses incurred by LESSOR by reason of the occurrence of any Event of
Default or the exercise of LESSOR's remedies with 



                                     -26-
<PAGE>
 
respect thereto, including all costs and expenses incurred in connection with
the return of all or any part of the Engines in accordance with Section 10 or
                                                                ----------
this Section 14 or in storing or maintaining the Engines or any part thereof or
     ----------
placing the same in the condition and airworthiness required by Section 10.
                                                                ---------- 

     Except as otherwise expressly provided above, no remedy referred to herein
is intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to herein or otherwise available to LESSOR at law or in
equity, and the exercise or beginning of exercise by LESSOR of any one or more
of such remedies shall not preclude the simultaneous or later exercise by LESSOR
of any or all such other remedies; provided, that LESSOR may recover only once
from each element of damages sustained and, provided further, that the preceding
proviso shall not be deemed to require proof of damages actually sustained in
the case of liquidated damages provided for herein.  No express or implied
waiver by LESSOR of any Default or Event of Default shall in any way be, or be
construed to be, a waiver of any future or subsequent Default or Event of
Default.  To the extent permitted by law, LESSEE hereby waives any rights now or
hereafter conferred by statute or otherwise (A) that may require LESSOR to lease
or otherwise use or dispose of the Engines or any part thereof in mitigation of
LESSOR's damages as set forth in this Section 14, (B) that may confer any right
                                      ----------                               
to prior notice or judicial hearing in connection with LESSOR's taking
possession or disposing of the Engines including, without limitation, any and
all prior notice and hearing for any prejudgment remedy or remedies and any such
right that LESSEE might otherwise have under applicable law, (C) except as
provided in this Section 14, that impose any requirements as to the time, place
                 ----------                                                    
or terms of lease other disposition or other requirements with respect to the
enforcement of LESSOR's rights and remedies hereunder, (D) all rights of
redemption, appraisement, valuation, stay, extension or moratorium now or
hereafter in effect under applicable law that may have the effect of delaying
the enforcement of this Lease or the absolute lease or other disposition of the
Engine, or (E) that may otherwise limit or modify any of LESSOR's rights or
remedies hereunder.  The failure or delay of LESSOR in exercising any right or
remedy granted it hereunder upon any occurrence of any of the contingencies set
forth herein shall not constitute a waiver of any such right or remedy upon the
continuation or recurrence of any such contingencies or similar contingencies
and any single or partial exercise hereunder of any particular right or remedy
of LESSOR shall not exhaust the same or constitute a waiver of any other right
provided herein.

     15.  Notices.  All notices required or permitted hereunder shall be in

to this Agreement, and each of LESSEE and LESSOR hereby irrevocably agrees that
all claims in respect of such action or proceeding may be heard and determined

Each of LESSEE and LESSOR hereby irrevocably waives, to the fullest extent it

MAY BE CHANGED, WAIVED, DISCHARGED OR TERMINATED, EXCEPT BY AN INSTRUMENT IN
WRITING SIGNED BY A DULY AUTHORIZED REPRESENTATIVE OF THE PARTY AGAINST WHICH
THE ENFORCEMENT OF THE CHANGE, WAIVER, DISCHARGE OR TERMINATION IS SOUGHT.  This
Lease shall constitute an agreement of lease, and nothing herein shall be
construed as conveying to LESSEE any right, title or interest in the Engines or
any Part except as a lessee only.

          (b)  English Language.  All notices, communications, reports,
               ----------------

any payment of Rent required to be made by it hereunder or fails to perform or
comply with any of its agreements contained herein, LESSOR may itself make such
payment or perform or comply with such agreement, and the amount of such payment
and the amount of any expenses of LESSOR incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may
be, shall be deemed Supplemental Rent payable by LESSEE upon demand; provided,
however, that no such payment, performance or compliance by LESSOR shall (i) be

          (d)  Application of Payments During Existence of Default.  Any
               ---------------------------------------------------        
amount referred to herein that is payable to LESSEE shall not be paid to LESSEE,
or if it has been previously paid directly to LESSEE, shall not be retained by
LESSEE, if at the time of such payment a Default or Event of Default shall have
occurred and be continuing, but shall be paid to and held by LESSOR as security
for and may be applied to the obligations of LESSEE under this Lease and, at
such time as LESSOR shall receive evidence in form and substance satisfactory to
it that there is not continuing any such Default or Event of Default, all such
amounts in excess of amounts so paid on obligations of LESSEE shall be paid to
LESSEE.

          (e)  Quiet Enjoyment.  LESSOR covenants that, if and so long as no
               ---------------                                                
Default or Event of Default shall have occurred and be continuing, LESSEE shall
quietly enjoy the Engines without interference by LESSOR or any Person lawfully
claiming by or through LESSOR.

          (f)  Expenses.  LESSEE agrees to reimburse LESSOR for LESSOR's out-
               --------                                                       
of-pocket costs and expenses, including attorney's fees, incurred in connection
with the preparation, negotiation and delivery of any amendments, modifications
or waivers required by this Lease or requested by LESSEE (or resulting from any
requests of LESSEE) hereunder.

          (g)  Further Assurances.  LESSEE will promptly and duly execute and
               ------------------                                              
deliver to LESSOR such further documents and assurances and take such further
action as LESSOR may from time to time reasonably request in order to more
effectively carry out the intent and purpose of this Lease and to establish and
protect the rights and remedies created or intended to be created in favor of
LESSOR hereunder.

          (h)  Invalidity of any Provision.  Any provision of this Lease that
               ---------------------------                                     
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.  To the fullest
extent permitted by applicable law, LESSEE hereby waives any provision of law
that renders any provision hereof prohibited or unenforceable in any respect.

          (i)  Headings.  All section and paragraph headings and captions are
               --------                                                        
purely for convenience of reference only and shall not modify, define, expand,
limit or otherwise affect any of the terms or provisions hereof and all
references herein to numbered sections, unless otherwise indicated, are to
sections of this Lease.

          (j)  Third Party Beneficiaries.  LESSEE recognizes that this Lease
               -------------------------                                      
confers certain rights and interests on the Indemnitees.  Notwithstanding that
the Indemnitees are not parties to this Lease, the Indemnitees are intended
third party beneficiaries of such rights and interests and LESSOR hereby
acknowledges that the Indemnitees may enforce such rights and interests
directly, as if they were parties to this Lease.

charge to the Revolving Loan on the date hereof.

          (b) Secretary's Certificate.  Agent shall have received a certificate

of the secretary of Borrower, which certificate shall be in form and substance
satisfactory to Agent, having attached thereto duly authorized resolutions of
the Board of Directors of the Borrower with respect to the transactions
contemplated hereby.

          (c) No Default.  No event shall have occurred and be continuing that
              ----------

this Amendment shall be consummated, Borrower agrees to promptly pay all
reasonable fees, costs and expenses incurred by Agent and each of the Lenders in
connection with any matters contemplated by or arising out of this Amendment or
the other Loan Documents including the following, and all such fees, costs and
expenses shall be part of the Obligations, payable on demand and secured by the
Collateral:  (a) fees, costs and expenses (including attorneys' fees, allocated

failure by Borrower to pay in a timely manner all taxes due is an Event of
Default.  Borrower has advised Agent that Borrower has failed to pay certain
excise taxes for the periods December 31, 1998, January 31, 1999 and February
28, 1999.  Borrower has requested a waiver from Agent and Agent hereby waives

conditioned upon (a) Borrower's payment of all excise taxes which are due in

reasonably acceptable to Agent no later than April 20, 1999.

separate counterparts, each of which when so executed and delivered shall be
deemed an original, but all of which counterparts together shall constitute but
one and the same instrument.  This Amendment shall become effective upon the
execution of a counterpart hereof by each of the parties hereto.  Delivery of an
executed counterpart of a signature page to this Amendment by telecopier shall
be as effective as delivery of a manually executed counterpart thereof.

          SECTION 10.  References.  Any reference to the Agreement contained in
                       ----------
