FOR IMMEDIATE RELEASE

                 INTERPOOL TO CONSIDER REDEMPTION OF SHARES OF
                 5 3/4% CUMULATIVE CONVERTIBLE PREFERRED STOCK

        PRINCETON, NJ, November 26, 1996 -- Interpool, Inc. (NYSE: IPX)
announced today that it is considering exercising its rights to redeem all or a
portion of its outstanding 5 3/4% Cumulative Convertible Preferred Stock
following December 15, 1996, the date on which such Preferred Stock becomes
redeemable in accordance with its terms. Interpool has a total of 758,414
shares of such 5 3/4% Preferred Stock outstanding, with an aggregate
liquidation preference of $75.8 million. The 5 3/4% Preferred Stock is
convertible into Interpool Common Stock at a price of $23.37 per share.

        If Interpool elects to redeem shares of its 5 3/4% Preferred Stock,
holders of 5 3/4% Preferred Stock would become entitled to receive the
redemption price of 103.675% of the face amount of the shares redeemed, except
to the extent holders exercised the right to convert shares of 5 3/4% Preferred
Stock into Common Stock. Any notice of redemption would be given at least 30
days prior to the redemption date fixed by Interpool.

        Interpool stated that it is considering various alternatives for
financing the redemption price of shares of 5 3/4% Preferred Stock called for
redemption and not converted into Common Stock. Among the alternatives being
examined is a public or private offering of preferred securities to be issued
by a grantor trust that would hold junior subordinated debentures of Interpool.
Any such public offering would be made only by means of a prospectus.

        Martin Tuchman, Chairman and Chief Executive Officer of Interpool,
stated that, "We believe that now may be an excellent time for us to call all
or part of our convertible preferred stock and reduce the over-hang that could
act as an artificial ceiling on the price of Interpool's common stock."

        Interpool, originally founded in 1968, is one of the world's leading
lessors of cargo containers used in international trade and is the second
largest lessor of intermodal container chassis in the United States. The
Company leases its containers and chassis to over 200 customers, including
nearly all of the world's 20 largest international container shipping lines.

                                                      NEWS FOR IMMEDIATE RELEASE


INTERPOOL, INC. REPORTS RECORD 4TH QUARTER INCOME PER SHARE BEFORE
NON-RECURRING CHARGE, AN INCREASE OF 17%; INTERPOOL INCREASES ANNUAL DIVIDEND
FROM 20 CENTS TO 22.5 CENTS PER COMMON SHARE.

PRINCETON, NJ, FEBRUARY 18, 1997 -- Interpool, Inc. (NYSE: IPX) reported today
that its 1996 fourth quarter income per share on a fully diluted basis, before
a non-recurring charge, rose 17% to 48 cents per share as compared with 41
cents per share for the same period in 1995. Revenues during the fourth quarter
of 1996 were $38,056,000, up 8% from $35,164,000 in 1995.

For the year ended December 31, 1996, income before extraordinary gain and
non-recurring charges rose to $38,088,000 from $29,545,000 in the same period a
year ago. Revenues for the year ended December 31, 1996 rose to $147,148,000,
up 15% from $127,925,000 in 1995. On a fully diluted basis, Interpool's income
per share before extraordinary gain and non-recurring charges rose 19% to
$1.79 for the year ended December 31, 1996 compared with $1.51 in 1995.

The company conducts its international container leasing business through its
subsidiary Interpool Limited, while the domestic intermodal equipment leasing
business is conducted by Interpool, Inc. and its other subsidiaries. During the
fourth quarter of 1996, the Interpool Limited international container
division's contribution to consolidated income rose 32% over the same period a
year ago to $8,020,000, while the domestic intermodal division's contribution
declined 9% to $2,263,000. Revenues for the fourth quarter of 1996 from the
Interpool Limited international container division rose 13% to $20,320,000
while revenues from the domestic intermodal division rose 3% to $17,736,000.

During the year ended December 31, 1996, the Interpool Limited international
container division's contribution to consolidated income rose 31% over the
prior year to $29,490,000, while the domestic intermodal division's
contribution declined slightly (on a pro-forma comparable basis) to $8,598,000.
Revenues for the year ended December 31, 1996 from the Interpool Limited
international container division rose 24% to $79,422,000, while revenues from
the domestic intermodal division rose 6% to $67,726,000.

Martin Tuchman, Chairman and Chief Executive Officer, commented that the
company's fully-diluted income per share before extraordinary gain and
non-recurring charges was a record, and was the direct result of the continued
expansion of Interpool's container and chassis fleets. During the past twelve
months, the company's container fleet has grown to approximately 301,000
container TEUs (twenty-foot equivalent units) from 241,000 TEU's, with
container utilization at 98%, while the chassis fleet has grown to
approximately 57,000 units from 54,000 units, with chassis utilization at 94%.

Mr. Tuchman indicated that Interpool had achieved another milestone, with
quarterly earnings before non-recurring items exceeding $10 million for the
first time in the company's history. He noted that "these outstanding results
reflect the continued success of our long-term leasing strategy, and the
underlying value of our business."

The company also announced that based upon its 1996 results, the Board of
Directors has approved a 12.5% increase in the annual dividend rate on
Interpool common stock from the current level of 20 cents per share to 22.5
cents per share (representing an increase to 5.625 cents per quarter). The
increase will become effective on the next quarterly common stock dividend
payment date, scheduled for April, 1997.

As previously announced, Interpool has called for redemption its 5-3/4%
Cumulative Convertible Preferred Stock, having an aggregate liquidation value
of $75.9 million. The company anticipates that, based upon the current market
price of the common stock, a significant number of preferred stockholders will
exercise their right to convert to common stock on or before the March 10, 1997
redemption date, given the economic benefits of conversion and the fact that
conversion would enable many holders to defer or avoid a taxable gain. Members
of Interpool's senior management who own approximately $10 million in aggregate
liquidation value of the 5-3/4% Preferred Stock have indicated that they intend
to convert all of their shares of 5-3/4% Preferred Stock into Common Stock.
Senior management have also indicated that they intend to continue adding to
their already substantial common stock position.

The company note that preferred stockholders who wish to convert will need to
submit a notice of conversion to the transfer agent on or before the March 10,
1997 redemption date of their preferred stock will automatically be redeemed
for cash.

Interpool, originally founded in 1968, is one of the world's leading lessors of
intermodal dry cargo containers and is the second largest lessor of intermodal
container chassis in the United States. Interpool leases its containers and
chassis to over 200 customers, including nearly all of the world's 20 largest

been $2,642 lower for the year ended December 31, 1995 and the provision for
income taxes would have been $1,004 higher for the year ended December 31,
1995. Therefore net income would have been $1,638 higher for the year ended
December 31, 1995. Fully diluted net income per share would not change because
the above mentioned effects were included in the fully diluted earnings per
share calculation.
