EXHIBIT 10 (iii)(t)

                         SEVERANCE PROTECTION AGREEMENT

      This Severance Protection Agreement (the "Agreement") is made as of the
12th day of December, 2003, by and between Overseas Shipholding Group, Inc., a
corporation incorporated under the laws of Delaware with its principal office at
511 Fifth Avenue, New York, New York 10017 (the "Company") and Robert E.
Johnston (the "Executive").

                              W I T N E S S E T H:

      WHEREAS, the Company believes that the continuation and maintenance of a
sound and vital management of the Company and its affiliates is essential to the
protection and enhancement of the interests of the Company and its stockholders;

      WHEREAS, the Company also recognizes that the search for, and hiring of, a
new chief executive officer ("CEO") of the Company may result in the departure
or distraction of key employees of the Company to the detriment of the Company;
and

      WHEREAS, the Company has determined that it is appropriate to take steps
to induce key employees to remain with the Company, and to reinforce and
encourage their continued focus and dedication.

      NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, the parties hereto hereby agree as follows:

      1. Term. The Protection Period under this Agreement shall commence on the
Commencement Date, which shall be the earlier of (a) the date a written
employment agreement is executed by the Company and an individual who shall
serve as the new CEO of the

<PAGE>

Company or (b) the date a new CEO (other than an interim CEO) commences
employment with the Company, and shall expire on the earlier of (a) eighteen
(18) months following the Commencement Date or (b) the date of the Executive's
termination of employment due to death, Disability (as defined in Section 2
below), retirement, resignation by the Executive with or without Good Reason (as
defined in Section 2 below) or termination by the Company with or without Cause
(as defined in Section 2 below).

      2. Termination. (a) If, during the Protection Period as provided in
Section 1 hereof, the Executive's employment with the Company is terminated by
the Company without Cause (as defined below) or by the Executive for Good Reason
(as defined below) the Executive shall be entitled to the amounts provided in
Section 3 as of the date of such termination (the "Termination Date").

      (b) For purposes of this Agreement, the following definitions shall apply:

            (i) Resignation for Good Reason. For purposes of this Agreement,
Resignation for Good Reason shall mean a resignation by the Executive effected
by a written notice of termination to the Company following the Executive's
thirty (30) day written notice to the Company of the occurrence of a Good Reason
event which is not materially cured by the Company within such thirty (30) day
period. "Good Reason" shall mean the occurrence of any of the following events
without the Executive's express written consent: (A) any material diminution in
the Executive's role, duties, responsibilities or authority, or the assignment
to the Executive of duties and responsibilities materially inconsistent with his
position, except in connection with the Executive's termination of employment
for Cause or as a result of the Executive's death, or temporarily as a result of
the Executive's incapacity or other absence; (B) a reduction in the Executive's
annual base salary; or (C) a relocation of the Executive's principal

<PAGE>

business location to an area outside of a fifty (50) mile radius of the
Executive's current principal business location and the Executive's home.

            (ii) Termination Without Cause. A termination without Cause shall be
a termination by the Company other than for Cause or Disability (each as defined
below).

      (A) As used herein, the term "Cause" shall mean: (I) the engaging by the
Executive in willful misconduct either (x) involving the Company or its assets,
business or employees, or (y) which is materially injurious to the Company
economically or to the Company's reputation; (II) the Executive's conviction or
indictment for (or pleading guilty or nolo contendere to) (x) a felony, or (y)
any other crime involving any financial or moral impropriety, or (z) any other
crime which, in the determination of the Board of Directors of the Company (the
"Board") would materially interfere with the Executive's ability to perform his
services to the Company or otherwise be materially injurious to the Company
economically or otherwise; (III) the continued and substantial failure by the
Executive to perform his duties with the Company (other than a failure resulting
from Executive's incapacity due to physical or mental illness or injury), which
failure has continued for a period of at least ten (10) days after written
notice thereof from the Company; (IV) the breach by the Executive of any
material provisions of any agreement with the Company, which breach is not cured
within ten (10) days after written notice thereof from the Company; or (V)
refusal to follow the legal written direction of the Board or a more senior
officer within five (5) business days of it being given, provided that the
foregoing refusal shall not be "Cause" if the Executive, in good faith, believes
that such direction is illegal and Executive promptly so notifies the Board.

<PAGE>

      (B) As used herein, the term "Disability" shall mean the Executive's
failure to perform his material duties and responsibilities as a result of
physical or mental illness or injury for one hundred eighty (180) days during a
three hundred sixty-five (365) day period.

      3. Severance Compensation. If, pursuant to Section 2, the Executive is
entitled to amounts and benefits under this Section 3, the Company shall,
subject to the provisions hereof, (a) pay to the Executive at the same time as
such amounts would be paid to the Executive if he had remained an employee (i)
for twenty-four (24) months an amount based on the Executive's highest annual
base salary rate in effect during the six (6) month period immediately prior to
his termination, less legally required taxes and any sums owed by the Executive
to the Company, (ii) subject to submission of documentation, any incurred but
unreimbursed business expenses for the period prior to termination payable in
accordance with the Company's policies and practices, and (iii) any base salary,
bonus, vacation pay or other compensation accrued or earned under law or in
accordance with the Company's policies applicable to the Executive but not yet
paid; (b) pay to the Executive any other amounts or vested benefits due under
applicable employee benefit (including, without limitation any Supplemental
Executive Retirement Plan), equity or incentive plans of the Company then in
effect, applicable to the Executive as shall be determined and paid in
accordance with such plans; and (c) provide for the benefit of the Executive and
the Executive's eligible dependents for a period ending at the earliest of (i)
the Executive and the Executive's eligible dependents ceasing to be eligible
under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA"), (ii)
eighteen (18) months following the Executive's Termination Date and (iii) the
Executive's commencement of other substantially full-time employment (such
period to be counted against the COBRA continuation coverage period), at the
Company's expense (subject to the Executive

<PAGE>

paying the same portion of premiums he paid as an active employee), continued
coverage under the Company health plans in which the Executive and the
Executive's eligible dependents participated immediately prior to the
Termination Date (or replacement plans therefor) .

      4. Acceptance and Release. Any and all amounts payable and benefits or
additional rights provided pursuant to Sections 3(a) and 3(c) of this Agreement
shall only be payable if the Executive delivers to the Company the attached
Acceptance Form and Release (Exhibit A) discharging all claims of the Executive
which may have occurred up to the Termination Date (with such changes therein as
may be necessary to make it valid and encompassing under applicable law) within
twenty-one (21) days of presentation thereof by the Company to the Executive.
Notwithstanding anything herein to the contrary, if the Executive materially
breaches any of the provisions of Section 6 of this Agreement, the Company may
cease all payments and benefits due to the Executive under Sections 3(a) and
3(c) hereof (other than as required by law).

      5. No Duty to Mitigate/Set-off. The Company agrees that if the Executive's
employment with the Company is terminated pursuant to this Agreement during the
term of this Agreement, the Executive shall not be required to seek other
employment or to attempt in any way to reduce any amounts payable to the
Executive by the Company pursuant to this Agreement. The amounts due under
Section 3 are inclusive, and in lieu of, any amounts payable under any other
salary continuation or cash severance arrangement of the Company and to the
extent paid or provided under any other such arrangement shall be offset against
the amount due hereunder.

      6.    (a) Confidentiality and Cooperation. The Executive shall not at any
time during the term of this Agreement, or thereafter, directly or indirectly,
for any reason

<PAGE>

whatsoever, communicate or disclose to any unauthorized person, firm or
corporation, or use for the Executive's own account, without the prior written
consent of the Board, any proprietary processes, trade secrets or other
confidential data or information of the Company and its related and affiliated
companies concerning their businesses or affairs, accounts, products, services
or customers, it being understood, however, that the obligations of this Section
shall not apply to the extent that the aforesaid matters (i) are disclosed in
circumstances in which the Executive is legally required to do so, provided that
the Executive gives the Company prompt written notice of receipt of notice of
any legal proceedings so as the Company has the opportunity to obtain a
protective order, or (ii) become known to and available for use by the public
other than by the Executive's wrongful act or omission. During and after his
employment, the Executive shall cooperate with the Company or its counsel in
connection with any matter, investigation, proceeding or litigation regarding
any matter in which the Executive was involved during his employment with the
Company or to which the Executive has knowledge based on his employment with the
Company.

            (b) Nonsolicitation. During the Executive's employment with the
Company and for the one (1) year period thereafter, the Executive agrees that he
will not, directly or indirectly, individually or on behalf of any other person,
firm, corporation or other entity, solicit, induce, hire or retain any employee
of the Company to leave the employ of the Company or to accept employment or
retention as an independent contractor with, or render services to or with any
other person, firm, corporation or other entity unaffiliated with the Company or
take any action to assist or aid any other person, firm, corporation or other
entity in identifying, soliciting, hiring or retaining any such employee
(provided the Executive may serve as a reference after he is no longer employed
by the Company but not with regard to any entity

<PAGE>

with which he is affiliated or from which he is receiving compensation).
Furthermore, during the Executive's employment with the Company and for the one
(1) year period thereafter, the Executive will not solicit or induce any
customer of the Company to purchase goods or services offered by the Company
from another person, firm, corporation or other entity or assist or aid any
other persons or entity in identifying or soliciting any such customer.

            (c) Agreement to Not Disparage. The Executive agrees that while
employed by the Company and thereafter, he will not make any statements that
disparage the Company or its employees, officers, directors, products or
services. Notwithstanding the foregoing, truthful statements made in the course
of sworn testimony in administrative, judicial or arbitral proceedings
(including, without limitation, depositions in connection with such proceedings)
by the Executive shall not be subject to this Section 6(c). Traditional
competitive statements made by the Executive but not based on his employment
with the Company, also shall not be deemed a violation of the foregoing if the
Executive is in a competitive position.

            (d) Equitable Relief and Other Remedies. Because the Company's
remedies at law for a breach or threatened breach of any of the provisions of
this Section would be inadequate, the Executive acknowledges and agrees that, in
the event of such a breach or threatened breach, in addition to any remedies at
law, the Company shall be entitled to obtain equitable relief in the form of
specific performance, a temporary restraining order, a temporary or permanent
injunction or any other equitable remedy which may then be available.

            (e) Reformation. If it is determined by a court of competent
jurisdiction that any restriction in this Section 6 is excessive in duration or
scope or is unreasonable or unenforceable, it is the intention of the parties
that such restriction may be modified or amended by the court to render it
enforceable to the maximum extent permitted.

<PAGE>

            (f) Survival of Provisions. The obligations contained in this
Section 6 shall survive the termination, separation, or expiration of the
Executive's employment with the Company and shall be fully enforceable
thereafter.

      7. Employee Benefit Plans. The amounts and benefits specified in Section 3
hereof shall not be paid to the Executive as an employee and the Executive shall
not be eligible to participate in employee benefit plans maintained by the
Company during such period except as specifically provided herein. Amounts paid
pursuant to Section 3 shall not be taken into account for purposes of
determining contributions to or calculating accrued benefits under the employee
benefit plans maintained by the Company.

      8. Non-Resignation. In consideration of this Agreement, the Executive
agrees that he shall not resign from the Company without Good Reason for at
least one hundred eighty (180) days from the date of this Agreement.

      9. Successors; Binding Agreement. In addition to any obligations imposed
by law upon any successor to the Company, the Company will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company to
expressly assume and agree in writing to perform this Agreement in the same
manner and to the same extent that the Company would have been required to
perform the Agreement if no such succession had taken place. This Agreement
shall inure to the benefit of and be enforceable by the Executive's personal or
legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees. If the Executive shall die while any amount
would still be payable to the Executive, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
the executors, personal representatives or administrators of the Executive's
estate, as if the Executive

<PAGE>

had continued to live. This Agreement is personal to the Executive and neither
this Agreement nor any rights or obligations hereunder may be assigned by the
Executive.

      10. Miscellaneous. No provisions of this Agreement may be modified, waived
or discharged unless such waiver, modification or discharge is agreed to in
writing and signed by the Executive and the CEO or other such officer as may be
specifically designated by the Board. No waiver of a breach under this Agreement
shall be deemed a waiver of similar or dissimilar provisions or conditions at
any time. This Agreement constitutes the entire Agreement between the Executive
and the Company with respect to the severance protection offered by the Company
to the Executive, except as may be provided in any other written agreement. This
Agreement is being executed for a limited purpose and for a specified Protection
Period (as set forth in Section 1 hereof). This Agreement does not confer or
impose any severance protection for the Executive following the termination of
the Protection Period. No agreements or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
either the Executive or the Company which are not expressly set forth in this
Agreement. All references to any law shall be deemed also to refer to any
successor provisions to such laws.

      11. Counterparts. This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

      12. Notices. Any notice or other communication required or permitted under
this Agreement shall be in writing and shall be delivered personally, or sent by
registered mail, postage prepaid. Any such notice shall be deemed given when so
delivered personally, or, if

<PAGE>

mailed, five (5) days after the date of deposit in the United States mails.
Notices and communications shall be delivered or sent to the following
addresses:

                  (i)   If to the Company, to:
                        Overseas Shipholding Group, Inc.
                        511 Fifth Avenue
                        New York, New York  10017
                        Attention: Chairman or CEO

                  (ii)  If to the Executive, to his or her last shown
                        address on the books of the Company.

      Any party may designate another address or person for receipt of notices
hereunder by providing notice as specified in this Section 12.

      13. Service with Any Subsidiary. For purposes of this Agreement,
employment with any subsidiary shall be deemed to be employment by the Company
and references to the Company shall include all such entities, except that the
payment obligation hereunder shall be solely that of the Company.

      14. Separability. If any provisions of this Agreement (including Exhibit
A) shall be declared to be invalid or unenforceable, in whole or in part, by a
court of competent jurisdiction, such invalidity or unenforceability shall not
affect the validity of the remaining provisions of this Agreement, including
Exhibit A.

      15. Non-Exclusivity of Rights. Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any benefit, bonus,
incentive, equity or other plan or program provided by the Company for which the
Executive may qualify, nor shall anything herein (except Section 6) limit or
otherwise prejudice such rights as the Executive may have under any other
currently existing plan, agreement as to employment or termination from

<PAGE>

employment with the Company or statutory entitlements. Amounts that are vested
benefits or those which the Executive is otherwise entitled to receive under any
plan or program of the Company, at or subsequent to the Termination Date, shall
be payable in accordance with such plan or program, except as otherwise
specifically provided herein. Notwithstanding the foregoing, the Executive shall
not be entitled to received duplicative severance payments and benefits and, to
the extent that the Executive is entitled to severance payments and benefits
under any other plan or agreement (for example, the Change of Control Agreement,
dated October 30, 1998, as amended on March 24, 1999, February 14, 2001 and June
21, 2002 between the Company and the Executive), the Executive shall be entitled
to the greater of the payments and benefits thereunder or hereunder but not
under both plans or agreements.

      16. At Will Employment. This Agreement does not constitute a contract of
employment and, subject to any other agreement between the Executive and the
Company, the Company reserves the right to terminate the Executive's employment
at any time with or without reason or notice (unless otherwise prohibited by
law), subject to the payment provisions hereof.

      17. Governing Law. This Agreement shall be construed, interpreted, and
governed in accordance with the laws of the State of Delaware without reference
to rules relating to conflicts of law.

<PAGE>

      IN WITNESS WHEREOF, the Company has caused this Agreement to be duly
executed and the Executive has hereunto set his hand as of the date first set
forth above.
