Caesar J. Belbel

[Address]

Dear Caesar:

This letter follows up on our recent discussions concerning the termination of
your employment with ZIOPHARM Oncology, Inc. (the “Company1”). To assist you in
your transition, the Company is offering to you certain transitional benefits in
exchange for the general release of claims and other terms set forth below.
Unless you rescind your assent as set forth in paragraph 10, this agreement
(“Agreement”) shall be effective on the eighth (8th) day after you sign it (the
“Effective Date”), at which time it shall become final and binding on all
parties.

The specific terms of the Agreement are as follows:

1. Termination of Employment. Your employment with the Company will end
effective February 15, 2018 (the “Separation Date”). The Company will pay you
all wages earned and any accrued and unused vacation time in accordance with the
Company’s policies through your Separation Date. You will receive these amounts
regardless of whether you sign this Agreement.

2. Transition Pay.

(a) As provided in your Amended and Restated Employment Agreement dated June 1,
2015 (“Employment Agreement”), subject to your execution of this Agreement, the
Company will provide you with a special lump sum transition payment in the gross
amount of $375,000 (the “Separation Payment”). This payment is an amount equal
to 100% of your current base salary.

(b) As also provided in the Employment Agreement, subject to your execution of
this Agreement, the Company will provide you with a lump sum payment in the
gross amount of $47,260.27 (the “Bonus Payment”). This payment is an amount
equal to your 2018 target bonus amount, prorated based upon your number of days
worked in 2018.

 

1  Except for the obligations set forth in paragraphs 2 and 3, which shall be
solely the obligations of ZIOPHARM Oncology, Inc., whenever the terms “ZIOPHARM
Oncology, Inc.,” or the “Company” are used in this Agreement (including, without
limitation, paragraph 9), they shall be deemed to include ZIOPHARM Oncology,
Inc. and any and all of its parents, predecessors, divisions, affiliates and
subsidiaries and all related entities, and its and their past and present
directors, officers, employees, agents, shareholders, trustees, members,
fiduciaries, successors and assigns.

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

(c) The Company reserves the right to withhold from any payments (including but
not limited to the Separation Payment and Bonus Payment) to you all sums that it
is required or allowed to withhold pursuant to applicable tax withholding laws
or regulations. You shall remain solely responsible for any and all income or
other taxes due by you or assessed against you on payments made to you.

(d) Any amounts you owe to the Company, such as outstanding personal advances,
loans, vacation time advances, expenses or any other amount shall be deducted
from any payments made to you.

(e) The amounts payable to you under this paragraph 2 will be made within 90
days after the Separation Date (the “Payment Commencement Date”); provided that
(1) the Company timely receives your executed Agreement, (2) you do not revoke
the release during the Revocation Period described in paragraph 10, and you have
returned all Company property described in paragraph 4 by such date. Failure to
meet each of these conditions by the Payment Commencement Date will result in
forfeiture of the amounts otherwise payable to you under this paragraph 2.

3. Benefits.

(a) Medical and Dental Insurance. Upon the termination of your employment, you
and your dependents may be eligible to continue your health and/or dental
insurance coverage under the company-sponsored plan(s) in which you were
enrolled during your termination (the “Plan”), pursuant to the terms of the Plan
and federal COBRA. If you are eligible, and in the event you elect COBRA
continuation coverage, in accordance with the Employment Agreement and subject
to your execution of this Agreement, the Company will pay the employer portion
of the premium cost of your continuation coverage for a period of twelve months
from your Separation Date (“Benefits Continuation”). You will remain responsible
for the employee portion of the premium cost. Thereafter, you will be
responsible for remitting the full premium cost for such continuation coverage.

You understand and acknowledge that it is solely your responsibility to elect
COBRA continuation coverage within the timeframe and in accordance with the
Plan’s procedures if you are eligible and you desire such coverage. Your rights
and obligations under such insurance plans shall be governed by the specific
terms of the Plans and COBRA. Information concerning COBRA rights, coverage and
election will be sent to you under separate cover.

(b) Stock Acceleration. Provided you execute this Agreement, pursuant to your
Employment Agreement, all Unvested Stock Awards (as defined in the Employment
Agreement) will vest as of the Separation Date.

(c) Time to Exercise Stock Options. Notwithstanding anything to the contrary in
the Employment Agreement, provided you execute this Agreement, you will have one
year from the Separation Date to exercise any vested Stock Options (as defined
in the Employment Agreement).

(d) Unemployment Compensation. The Company agrees that if you decide to seek
unemployment compensation benefits, it will not contest your application for
unemployment compensation. The Company, however, will not provide any false
information to the state agency. The Company makes no representations concerning
your eligibility for unemployment compensation. You acknowledge and understand
that any determination as to your eligibility for unemployment compensation is
made solely by the state agency to which you apply for such benefits.

(e) Other Benefits. Except as specifically set forth in this Agreement, and
except as to any vested benefits, your right to, and participation in, all
employee benefit plans of the Company shall terminate as of your Separation Date
in accordance with the specific terms of each plan. To the extent you have any
vested assets in any employee benefit plan of the Company, the status and
treatment of any such assets shall be governed by the applicable terms of such
plan.

against the Company (as defined in footnote number 1) of any kind whatsoever
from the beginning of time through and including the date you sign this

or otherwise), the recovery of any damages or any other form of monetary
recovery whatsoever (including, without limitation, back pay, front pay,

permitted by law of the economic benefits provided to you under this Agreement
in the event that you successfully challenge the validity of this release and

INVENTION, NON-DISCLOSURE AND

NON-COMPETITION AGREEMENT

This Agreement is made this 6th day of September, 2011, between ZIOPHARM
Oncology, Inc., having an address at One First Avenue, Parris Building #34, Navy
Yard Plaza, Boston MA 02129 (hereinafter referred to as the “Company”), and
Caesar J. Belbel, having an address at [Address] (“EMPLOYEE”).

In consideration of the employment or the continued employment of the Employee
by the Company, the Company and the Employee agree as follows:

 

1. Proprietary Information

(a) The Employee agrees that all information, whether or not in writing, of a
private, secret or confidential nature concerning the Company’s business,
business relationships or financial affairs (collectively, “Proprietary
Information”) is and shall be the exclusive property of the Company. By way of
illustration, but not limitation, Proprietary Information may include
inventions, products, processes, methods, techniques, formulas, compositions,
compounds, projects, developments, plan, research data, clinical data, financial
data, personnel data, computer programs, customer and supplier lists, and
contacts at or knowledge of customers or prospective customers of the Company.
The Employee will not disclose any Proprietary Information to any person or
entity other than employees of the Company or use the same for any purposes
(other than in the performance of his/her duties as an employee of the Company)
without written approval by an officer of the Company, either during or after
his/her employment with the Company, unless and until such Proprietary
Information has become public knowledge without fault by the Employee.

(b) The Employee agrees that all files, letters, memoranda, reports, records,
data, sketches, drawings, laboratory notebooks, program listings, or other
written, photographic, or other tangible material containing Proprietary
Information, whether created by the Employee or others, which shall come into
his/her custody or possession, shall be and are the exclusive property of the
Company to be used by the Employee only in the performance of his/her duties for
the Company. All such materials or copies thereof and all tangible property of
the Company in the custody or possession of the Employee shall be delivered to
the Company, upon the earlier of (i) a request by the Company or
(ii) termination of his/her employment. After such delivery, the Employee shall
not retain any such materials or copies thereof or any such tangible property.

(c) The Employee agrees that his/her obligation not to disclose or to use
information and materials of the types set forth in paragraphs (a) and (b)
above, and his/her obligation to return materials and tangible property, set
forth in paragraph (b) above, also extends to such types of information,
materials and tangible property of customers of the Company or suppliers to the
Company or other third parties who may have disclosed or entrusted the same to
the Company or the Employee.

 

2. Developments

(a) The Employee will make full and prompt disclosure to the Company of all
inventions, improvements, discoveries, methods, developments, software, and
works of authorship, whether patentable or not, which are created, made,
conceived, or reduced to practice by him/her or under his/her direction or
jointly with others during his/her employment by the Company whether or not

during normal working hours or on the premises of the Company (all of which are
collectively referred to in this Agreement as “Developments”).

 

A-1

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

(b) The Employee agrees to assign and does hereby assign to the Company (or any
person or entity designated by the Company) all his/her right, title and
interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. However, this paragraph
2(b) shall not apply to Developments which do not relate to the present or
planned business or research and development of the Company and which are made
and conceived by the Employee not during normal working hours, not on the
Company’s premises and not using the Company’s tools, devices, equipment or
Proprietary Information. The Employee understands that, to the extent this
Agreement shall be construed in accordance with the law of any state which
precludes a requirement in an employee agreement to assign certain classes of
inventions made by an employee, this paragraph 2(b) shall be interpreted not to
apply to any invention which a court rules and/or the Company agrees falls
within such classes. The Employee also hereby waives all claims to moral rights
in any Developments.

(c) The Employee agrees to cooperate fully with the Company, both during and
after his/her employment with the Company, with respect to the procurement,
maintenance and enforcement of copyrights, patents and other intellectual
property rights (both in the United States and foreign countries) relating to
Developments. The Employee shall sign all papers, including, without limitation,
copyright applications, patent applications, declarations, oaths, formal
assignments, assignments of priority rights, and powers of attorney, which the
Company may deem necessary or desirable in order to protect its rights and
interest in any Development. The Employee further agrees that if the Company is
unable, after reasonable effort, to secure the signature of the Employee on any
such papers, any executive officer of the Company shall be entitled to execute
any such papers as the agent and the attorney-in-fact of the Employee, and the
Employee hereby irrevocably designates and appoints each executive officer of
the Company as his/her agent and attorney-in-fact to execute any such papers on
his/her behalf, and to take any and all actions as the Company may deem
necessary or desirable in order to protect its rights and interests in any
Development, under the conditions described in this sentence.

 

3. Non-competition

(a) While the Employee is employed by the Company and for a period of one year
after the termination or cessation of such employment for any reason, the
Employee will not directly or indirectly:

(i) as an individual proprietor, partner, stockholder, officer, employee,

whatsoever (other than as the holder of not more than one percent of the
combined voting power of the outstanding stock of a publicly held company),
engage in the business of developing, designing, producing, marketing, selling
or rendering (or assisting any other person in developing, designing, producing,
marketing, selling or rendering) oncology products in the class of arsenicals,
products in the phosphoramidic nitrogen mustard family and “mustard gas family,”
anti-mitotics with the same mechanism as that in indibulin, and DNA-based
biotherapeutic products involving in vivo expression of effectors for the
treatment of cancer, or other products or product candidates that are in the
same chemical family as or are otherwise substantially similar to those that
have been or are being developed, designed, produced, marketed, sold or rendered
by the Company while the Employee was employed by the Company; or

(ii) solicit, divert or take away, or attempt to divert or to take away, the
business or patronage of any of the clients, customers or accounts, or

period of one year has expired without any violation of such provisions.

 

4. Non-Solicitation

(a) While the Employee is employed by the company and for a period of two years
after the termination or cessation of such employment for any reason, the
Employee will not directly or indirectly recruit, solicit or hire any employee
of the Company, or induce or attempt to induce any employee of the Company to
terminate his/her employment with, or otherwise cease his/her relationship with,
the Company.

(b) If the Employee violates the provisions of Section 4(a), the Employee shall
continue to be bound by the restrictions set forth in Section 4(a) until a
period of two years has expired without any violation of such provisions.

 

5. Other Agreements

The Employee hereby represents that, except as the Employee has disclosed in
writing to the Company on Appendix A to this Agreement, the Employee is not
bound by the terms of any agreement with any previous employer or other party to
refrain from using or disclosing any trade secret or confidential or proprietary
information in the course of his/her employment with the Company or to refrain
from competing, directly or indirectly, with the business of such previous
employer or any other party. The Employee further represents that his/her
performance of all the terms of this Agreement and as an employee of the Company
does not and will not breach any agreement to keep in confidence proprietary
information, knowledge or data acquired by the Employee in confidence or in
trust prior to his/her employment with the Company, and the Employee will not
disclose to the Company or induce the Company to use any confidential or
proprietary information or material belonging to any previous employer or
others.

 

6. United States Government Obligations

The Employee acknowledges that the Company from time to time may have agreements
with the other persons or with the United States Government, or agencies
thereof, which impose obligations or restrictions on the Company regarding
inventions made during the course of work under such agreements or regarding the
confidential nature of such work. The Employee agrees to be bound by all such
obligations and restrictions which are made known to the Employee and to take
all action necessary to discharge the obligations of the Company under such
agreements.

 

7. No Employment Contract

The Employee understands that this Agreement does not constitute a contract of
employment and does not imply that his/her temporary employment will continue
for any period of time.

 

8. Miscellaneous

(a) The invalidity or unenforceability of any provision of this Agreement shall
not affect the validity or enforceability of any other provision of this
Agreement.

(b) This Agreement supersedes all prior agreements, written or oral, between the
Employee and the Company relating to the subject matter of this Agreement.

 

A-3

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

(c) This Agreement may not be modified, changed or discharged in whole or in
part, except by an agreement in writing signed by the Employee and the Company.
The Employee agrees that any change or changes in his/her duties, salary or
compensation after the signing of this Agreement shall not affect the validity
or scope of this Agreement.

(d) No delay or omission by the Company in exercising any right under this
Agreement will operate as a waiver of that or any other right. A waiver or
consent given by the Company on any one occasion is effective only in that
instance and will not be construed as a bar to or waiver of any right on any
other occasion.

(e) The Employee expressly consents to be bound by the provisions of this
Agreement for the benefit of the Company or any subsidiary or affiliate thereof
to whose employ the Employee may be transferred without the necessity that this
Agreement be resigned at the time of such transfer.

(f) The restrictions contained in this Agreement are necessary for the
protection of the business and goodwill of the Company and are considered by the
Employee to be reasonable for such purpose. The Employee agrees that any breach
of this Agreement is likely to cause the Company substantial and irrevocable
damage and therefore, in the event of any such breach, the Employee agrees that
the Company, in addition to such other remedies which may be available, shall be
entitled to specific performance and other injunctive relief.
