OSG Announces Record Date for Spin-Off of International Flag Business

NEW YORK –
Overseas Shipholding Group, Inc. (NYSE:OSG) today announced the record
date for the previously announced spin-off of its International flag
business. The spin-off will separate the international and domestic
businesses of OSG into two independent, publicly traded companies:
Overseas Shipholding Group and International Seaways (“INSW”), (formerly
known as OSG International, Inc.).

The spin-off is expected to be effective as of 5:00 p.m. on Nov. 30,
2016, the distribution date for the spin-off, with 100 percent of the
shares of International Seaways distributed to OSG shareholders and
warrantholders. OSG shareholders will receive 0.3333 shares of
International Seaways common stock for every one share of OSG common
stock held at 5:00 p.m. on November 18, 2016, the record date for the
spin-off. For each OSG warrant held on the record date, OSG
warrantholders will receive 0.3333 shares of INSW common stock for every
one share of OSG common stock they would have received if they exercised
those warrants immediately prior to the distribution date (or
approximately 0.06332 INSW shares per warrant). OSG shareholders and
warrantholders will receive cash in lieu of any fractional shares.

International Seaways has received authorization to list its shares on
the New York Stock Exchange (NYSE) under the symbol “INSW.” OSG expects
that a “when-issued” public trading market for International Seaways
common stock will begin on the NYSE on or about November 16, 2016, under
the symbol “INSW WI” and will continue through the distribution date.
International Seaways common stock is expected to begin “regular way”
trading on the NYSE on December 1, 2016, the first trading day following
the distribution date.

No action is required by OSG shareholders or warrantholders to receive
shares of International Seaways common stock in the spin-off. Beginning
on or about November 16, 2016, through the distribution date, it is
expected that there will be two ways to trade OSG common stock – either
with or without the right to receive International Seaways common stock
in the spin-off. Investors are encouraged to consult with their broker
and financial and tax advisors regarding the specific implications of
buying or selling OSG common stock on or before the distribution date.

The spin-off and the distribution of International Seaways common stock
is subject to the U.S. Securities and Exchange Commission (SEC) having
declared effective International Seaways’ registration statement on Form
10. In addition, the spin-off is subject to conditions set forth in a
Separation and Distribution Agreement between OSG and International
Seaways, the form of which is filed as an exhibit to International
Seaways registration statement on Form 10.
