1.       Operations
         ----------

The accompanying unaudited consolidated financial statements have been prepared
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, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three and nine month periods ended
September 30, 1999 are not necessarily indicative of the results that may be
expected for the year ended December 31, 1999.

The balance sheet at December 31, 1998 has been derived from the audited
financial statements at that date but does not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements.

For further information, refer to the consolidated financial statements and
footnotes thereto included in the Company's annual report on Form 10-K for the
year ended December 31, 1998.

The management agreement under which the Company operated the Sonesta Beach
Resort & Casino, Curacao was terminated on June 1, 1999. The Company received a
termination fee of $1,875,073, which is based on the equity investment of
$2,000,000 the Company made in the hotel in 1994, less incentive fees earned in
1998 of $124,927. This termination fee was included in Other income in the
consolidated statement of operations in the second quarter of 1999. The carrying
value of the investment had previously been written down to zero through the
recognition by the Company of its equity in losses sustained by the hotel.

The Company operates the Sonesta Beach Resort Bermuda under a management
agreement. The owner of the hotel has the right to terminate the agreement in
the event of a sale of the hotel. In return for this right of termination, the
Company was entitled to a supplemental fee of $2,000,000 on the earlier of (1) a
sale of the hotel or (2) June 4, 1999. The Company received the supplemental fee
in June 1999 and recorded this as Other income in the consolidated statement of
operations in the second quarter of 1999.

During the second quarter of 1999, the Company settled a legal dispute with the
seller of the Sonesta Beach Resort Anguilla, a hotel that the Company acquired
in November 1995. In connection with the settlement, the Company repaid an
$800,000 loan from the seller that was related to the purchase of the hotel. The
loan had originally matured in November 1998.

Included in the results from operations as of July 1, 1998 are the revenues and
expenses from Sonesta Beach Resort Key Biscayne. Before the acquisition on July
1, 1998, the Company operated the hotel under a management agreement.

(a)      This loan is secured by a first mortgage on the Royal Sonesta Hotel
         Boston (Cambridge) property. This property is included in fixed assets
         at a net book value of approximately $25,377,000 at September 30, 1999.
         The interest rate on the loan is 8.86% for the term of the loan, and
         monthly payments for interest and principal are $203,802. The mortgage

         balance of this loan is $22,431,000. The Company recorded an additional
         liability in 1998 when it assumed the loan to reflect the fair market

         additional liability is being amortized as an adjustment to interest
         expense over the remaining life of the loan. The loan requires monthly
         interest payments based on a rate of 11.78% until March 1, 1999, and
         12.78% from March 1, 1999 until the maturity date, which is October 1,
         2000. Additional interest will become due in case the loan is not
         repaid on the scheduled maturity date. No provision for such payment is
         included in the accompanying consolidated balance sheets. No principal
         payments are due during the term of the loan.

Total revenues for the first nine months of 1999 were $74,889,000 compared to
$57,190,000 in 1998, an increase of approximately $17,699,000.

The Company acquired the Sonesta Beach Resort Key Biscayne on July 1, 1998.
Revenues of this resort during the nine-month period ending September 30, 1999
were $20,801,000 compared to $18,887,000 during the same period in 1998. During
the first six months of 1998, the Company operated the hotel under a management
agreement. The increase in revenues of approximately $1,914,000 was due to a 5%
increase in the resort's average room rate, a slight increase in occupancy
levels, and increased food and beverage revenues. The Company's Sonesta Beach
Resort Anguilla reported an increase in revenues of $737,000 during the first
nine months of 1999 compared to the same period in 1998, due to a 5% increase in
the hotel's room revenue per available room ("REVPAR"), increased food and
beverage revenues, and an increase in revenue from the hotel's retail shops. At
the Royal Sonesta Hotel Boston (Cambridge), revenues in the first three quarters
of 1999 increased by approximately $447,000 due to an 8% increase in average
room rate partially offset by slight decreases in both occupancy levels and the
hotel's banquet revenues. Revenues at the Royal Sonesta Hotel New Orleans rose
$1,177,000 in 1999 compared to the first nine months of 1998, primarily due to a
5% increase in REVPAR and a 7% increase in food and beverage revenues. Revenues
from management activities decreased by $1,545,000 during the first three
quarters of 1999 compared to 1998. The 1998 revenues included fee income of
$669,000 from Sonesta Beach Resort Key Biscayne, which was operated by the
Company under a management agreement until its acquisition on July 1, 1998. The
1998 revenues also included a cancellation fee of $335,000 in connection with
the termination of a license agreement for a hotel in Santiago, Chile, and
additional fee income of $407,000 for previously deferred fees from Chateau
Sonesta Hotel New Orleans. In addition, the 1998 revenues included $266,000 of
service fees to an in-house advertising agency, which function was outsourced as
of January 1, 1999. These decreases in fee income were partially offset by
increases in fee income from the Company's operations in Egypt.

Operating income for the nine-month period ending September 30, 1999 was
$7,240,000, compared to operating income of $3,167,000 in 1998, an increase of
approximately $4,073,000.

Operating income of the Sonesta Beach Resort Key Biscayne, which the Company
acquired on July 1, 1998, was $3,200,000 in the first nine months of 1999.
Included in the 1998 results is a seasonal loss during the third quarter only of
$1,168,000. Operating loss at the Sonesta Beach Resort Anguilla decreased by
$429,000 in the first nine months of 1999 compared to the previous year due to
increased revenues of $737,000, partially offset by a $308,000 increase in
expenses. Royal Sonesta New Orleans experienced a $198,000 increase in operating
income due to an increase in revenues of $1,177,000, which was partially offset
by a $979,000 increase in total expenses, primarily rent and cost and operating
expenses. During the first nine months of 1999, operating income at the Royal
Sonesta Hotel Boston (Cambridge) increased slightly by $15,000 compared to 1998,
due to a $447,000 increase in revenues offset by a $432,000 increase in total
operating expenses. Operating loss from management and other activities, which
is computed after giving effect to management, marketing and service fees to the
Company's owned and leased hotels, increased by $937,000 in 1999 compared to
1998. The 1998 loss included a one-time fee payment of $335,000 in connection
with the cancellation of a license agreement for a hotel in Santiago, Chile, and
additional fee income of $407,000 for previously deferred fees from Chateau
Sonesta Hotel New Orleans. In addition, fee income from the Sonesta Beach Resort
& Casino, Curacao decreased by $179,000 in 1999 compared to 1998 as a result of
the termination of the Company's management agreement effective June 1, 1999.

OTHER INCOME (DEDUCTIONS)
-------------------------

Interest expense increased from $2,660,000 in the first nine months of 1998 to
$3,475,000 in 1999, primarily due to increased interest expense of $1,026,000 on
indebtedness related to the Sonesta Beach Resort Key Biscayne, which was
acquired by the Company on July 1, 1998. Interest income decreased by $203,000
in the first nine months of 1999 compared to the same period in 1998, mainly due
to interest of $275,000 included in the first six months of 1998 from
receivables due from the previous owner of Sonesta Beach Resort Key Biscayne.
These receivables were settled when the Company acquired the hotel on July 1,
1998. This decrease was partially offset by increases in interest income from
the Company's loans to Sonesta Beach Resort Sharm El Sheikh and by interest
received from Sonesta Beach Resort & Casino, Curacao as a result of the late
payment of a termination fee.

Operating income for the three-month period ending September 30, 1999 was
$734,000, compared to operating income of $5,000 in 1998, an increase of
approximately $729,000.

Operating losses at the Sonesta Beach Resort Key Biscayne in the third quarter
of 1999 decreased by $360,000 compared to the previous year's quarter, due to
increased revenues of $822,000 offset by increases in total expenses of
$462,000. Operating income at the Royal Sonesta Hotel Boston (Cambridge)
increased by $293,000 in 1999 compared to 1998, due to an increase in revenues
of $619,000, partially offset by increased expenses of $326,000. Royal Sonesta
Hotel New Orleans had a slight increase in operating income of $149,000, due to
an increase in revenues of $883,000, which was offset by a $734,000 increase in
total expenses, primarily rent and cost and operating expenses. The Sonesta
Beach Resort Anguilla had a slight decrease of $15,000 in operating losses, due
to increased revenues of $281,000 which was offset by a $266,000 increase in

computed after giving effect to management, marketing and service fees to the
Company's owned and leased hotels, increased by $88,000 in the third quarter of
1999 compared to 1998. Expense increases of $269,000 related to management and
other activities were partially offset by a $181,000 increase in fee income
during the third quarter of 1999 compared to 1998.

OTHER INCOME (DEDUCTIONS)
-------------------------

Interest expense decreased by $86,000 in the third quarter of 1999 compared to
the 1998 quarter, primarily due to the repayment of two loans during the second
quarter of 1999 (see note 4 - Long Term Debt). Interest income decreased by
$53,000 in the third quarter of 1999 compared to the same period in 1998 due to
lower short term investment interest income from the Company's decreased cash
balances, and due to interest income recorded in the third quarter of 1998 on
previously deferred management fees related to the Chateau Sonesta Hotel in New
Orleans.

FEDERAL, FOREIGN AND STATE INCOME TAXES
---------------------------------------

The provision for income taxes for the first nine months of 1999 was higher than
the statutory rate due to state taxes provided on the Company's profits from its
operations in Louisiana, Florida, and Massachusetts.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL
CONDITION (CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

The Company had cash and cash equivalents of approximately $4,300,000 at
September 30, 1999. The Company also has $7,000,000 available under two lines of
credit, and no amounts were outstanding under these lines at September 30, 1999.

The Company had a working capital deficit of approximately $4,005,000 at
September 30, 1999. Included in current liabilities is accrued rent of
approximately $4,761,000 for 1999 due under the lease for the Royal Sonesta
Hotel New Orleans. This 1999 rent is not due until March 2000, and the Company
expects to pay this liability out of future cash flow and, if needed, out of
proceeds from borrowings under its lines of credit.

The first mortgage note of $22,431,000 related to Sonesta Beach Resort Key
Biscayne matures on October 1, 2000. The Company is currently seeking to
refinance this debt and, considering the resort's history of substantial cash
flows, foresees no difficulty in acquiring such replacement financing.

On July 1, 1999, the Company paid $3,772,800 related to a treasury stock
purchase (see Note 5-Capital Transactions).

The Company believes that its present cash balances, plus available borrowing
capacity and the expected cash flow generated during the remainder of the
calendar year 1999, will be more than adequate to meet all of its obligations.


YEAR 2000 COMPLIANCE
--------------------

The Company has completed its program to address issues related to the year
2000, and believes that substantially all of its automated systems are
compliant. Management at the hotels and the corporate office are finalizing
contingency plans. Company management believes that the compliance program that
it has executed over the past three years, as well as the contingency plans it
will have in place, will reduce the possibility of major interruptions of normal
operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURE OF MARKET RISK

The Company is exposed to market risk from changes in interest rates and foreign
exchange rates. The Company uses fixed rate debt and debt with variable interest
rates to finance the ownership of its properties. The Company does not believe
that there have been any material changes in its market risk exposure since
December 31, 1998.
