Description of Employment Agreements and Related Compensation

Employment Agreement with Jonathan Lewis, M.D., Ph.D.

During the fiscal year ended December 31, 2007, Dr. Jonathan Lewis served as the Company’s Chief Executive Officer under an employment agreement dated January 8, 2004. Under that agreement, as amended, Dr. Lewis received an annual base salary of $385,000 and a guaranteed annual bonus of $250,000. In addition, Dr. Lewis was eligible to receive an annual discretionary bonus of up to 100% of his base salary, as determined by the compensation committee of our Board of Directors, as well as stock options that may be granted in the discretion of the compensation committee.

The Company’s practice has been to evaluate compensation and related job performance at the end of each fiscal year and grant cash bonuses and/or stock options to employees based upon such evaluation.  During fiscal 2007, the compensation committee determined to pay Dr. Lewis a discretionary cash bonus of $65,000 for his job performance in fiscal 2007. This determination was based on the Company meeting or exceeding previously set 2007 operational goals. In addition, the Company granted Dr. Lewis a stock option to purchase 35,000 shares of common stock at a per share exercise price of $4.85 on June 18, 2007 and a year-end stock option to purchase 100,000 shares of common stock at a per share exercise price of $2.73.  Such options vest in annual installments over three years commencing on the one year anniversary of the date of grant.

On January 18, 2008, the Company entered into a new employment agreement with Dr. Lewis that was retroactively effective as of the January 8, 2008 expiration date of his prior agreement. Under the new agreement, which has a three year term commencing January 8, 2008, Dr. Lewis received an initial annual base salary of $420,000, which is subject to increase at the discretion of the Board of Directors based on an annual review. Based on its year-end review for fiscal 2009, the Board of Directors increase Dr. Lewis’ annual base salary for 2010 to $460,000.  In addition, Dr. Lewis is eligible to receive an annual bonus based on his performance as determined by the Board of Directors. The target amount of the annual performance is a range from $250,000 to $360,000.  The agreement contemplates that Dr. Lewis and the Company’s compensation committee will agree on certain performance targets each year.  The actual amount received will be based on whether each of these targets have been achieved by the Company, with lesser amounts paid if substantial progress has been made to achieve the goal or it has been abandoned by the Company, and greater amounts paid if expectations are exceeded. Dr. Lewis is also eligible to receive an additional annual discretionary bonus in such amounts determined by the Board of Directors.

10

On December 5, 2008, the employment agreement with Dr. Lewis was amended to provide for a restricted stock grant of 150,000 shares, with restrictions that lapsed on December 3, 2009, in lieu of the cash bonus for fiscal year 2008 that Dr. Lewis would otherwise have been eligible to receive. Replacing Dr. Lewis’ cash bonus potential with a restricted stock grant was in accordance with the Company’s efforts to conserve cash. The Company’s other senior management employees also received restricted stock grants in accordance with these efforts.

Under his current agreement, Dr. Lewis is eligible for reimbursement of reasonable out-of-pocket expenses incurred by him in furtherance of the business and affairs of the Company, including reasonable travel and entertainment expenses, as well as for medical licensing fees, professional dues and memberships, journal subscriptions and up to $10,000 per year in costs associated with certain corporate consultants retained by Dr. Lewis. In addition, the Company has agreed to reimburse Dr. Lewis for premiums on life insurance policies having aggregate coverage limits of up $800,000 and premiums on disability insurance policies covering Dr. Lewis in amounts up to $20,000 per month.

In connection with entering into the current agreement, the Company granted Dr. Lewis an award of restricted stock in the amount of 100,000 shares. The restricted stock award is governed by an agreement that prohibits Dr. Lewis from transferring the restricted shares and provides that the shares will be forfeited without consideration if Dr. Lewis’s employment with the Company is terminated. The transfer restrictions and forfeiture obligations lapse in three equal annual installments on January 8, 2009, January 8, 2010 and January 8, 2011. Accordingly, 66,666 shares have vested effective as of January 8, 2010. Dr. Lewis will also be eligible to receive additional equity awards as determined by the Board of Directors in its sole discretion from time to time.

On May 13, 2009, the Company granted to Dr. Lewis options to purchase 100,000 shares of the Company’s common stock at an exercise price of $0.70, which options vest or vested in four equal installments on each of May 13, 2009, August 13, 2009, November 13, 2009, and February 13, 2010. Effective as of December 31, 2009, the Board of Directors’ adopted the compensation committee’s recommendations for 2009 end-of-year cash bonuses, awards of restricted stock and grants of stock options under the Company’s 2003 Stock Option Plan.  Dr. Lewis received a cash bonus of $200,000 and was awarded 150,000 shares of the Company’s common stock with transfer and forfeiture restrictions.  The stock vests and the restrictions lapse in annual installments over three years commencing on the one-year anniversary of the grant date.  The Company also granted Dr. Lewis options to purchase 150,000 shares of the Company’s common stock at an exercise price of $2.85, which options vest in equal annual installments over three years commencing on the one year anniversary of the grant date.

Dr. Lewis’ employment agreement provides that he will continue to receive his base salary, benefits and a pro-rata portion of his target performance bonus for a period of one year if he is terminated by the Company for a reason other than death, disability or “Cause,” or if Dr. Lewis resigns for “Good Reason,” each as defined in the employment agreement. In connection with any such termination, the pro rata potion of Dr. Lewis’s performance bonus will be based on the number of days Dr. Lewis has been employed by the Company during the year of termination. In the event Dr. Lewis’s employment is terminated without “Cause” prior to and in connection with a “Change in Control,” or within 18 months thereafter, he will continue to receive his base salary and benefits for a period of two years following such termination and will also receive the greater of the amount of his performance bonus for the year of termination or the average of the amounts received as a performance bonus under the new employment agreement or guaranteed bonus under the previous employment agreement for the two years preceding the year of termination. If Dr. Lewis’s employment is terminated as a result of death or disability, Dr. Lewis (or his estate, as applicable) will receive his base salary for a period of one year following the date of termination. Upon occurrence of any of the above termination events, all stock options and restricted stock grants scheduled to vest by the end of the calendar year in which such termination occurs will be accelerated and deemed to vest as of the termination date.

The employment agreement provides that Dr. Lewis will not compete with the Company, or solicit employees, clients or customers of the Company, for twelve months after the termination of his employment with the Company; provided, however, that the Company will be obligated to pay Dr. Lewis his base salary and his performance bonus (based on Dr. Lewis’s average performance bonus received for the prior two years) if the Company desires such non-competition and non-solicitation provisions to have effect following expiration of the employment agreement without renewal.

Employment Agreement with Richard E. Bagley

During the fiscal year ended December 31, 2007, Mr. Richard E. Bagley served as the Company’s President, Chief Operating Officer, Chief Financial Officer, and Treasurer under a written three-year employment agreement dated July 21, 2004 and effective July 1, 2004. Under the agreement, Mr. Bagley initially received an annual base salary of $250,000 (subject to adjustment) and a guaranteed annual bonus of $50,000. In addition, Mr. Bagley was eligible to receive an annual discretionary bonus as determined by the compensation committee of our Board of Directors, as well as stock options that may be granted at the discretion of the compensation committee.  Following approval by the Company’s Board of Directors at a meeting held June 18, 2007, the Company entered into an Employment Agreement Extension with Mr. Bagley, pursuant to which the Company extended the term of Mr. Bagley’s employment for an additional one-year period at his then-current annual base salary of $275,000.

During fiscal 2007, the compensation committee determined to pay Mr. Bagley a discretionary cash bonus of $55,000 for his job performance in fiscal 2007.  This determination was based on the Company’s meeting or exceeding its previously set 2007 operational goals.  In addition, the Company granted Mr. Bagley a stock option to purchase 25,000 shares of common stock at a per share exercise price of $4.85 on June 18, 2007 and a year-end stock option to purchase 75,000 shares of common stock at a per share exercise price of $2.73. Such options vested in annual installments over three years commencing on the one year anniversary of the date of grant.  As part of a year-end grant of stock awards to certain of the Company’s employees, the Company granted 25,000 shares of the Company’s common stock to Mr. Bagley on December 1, 2008, which shares were subject to transfer and forfeiture restrictions that lapsed on the one-year anniversary of the grant date.

11

The target amount of the annual performance bonus is $100,000, and the actual amount to be received will be based on the achievement of certain performance goals to be agreed upon by Mr. Bagley and the Board’s compensation committee for each calendar year. Mr. Bagley is also eligible to receive an additional annual discretionary bonus in such amount as may be determined by the Board of Directors.

On December 5, 2008, the employment agreement with Mr. Bagley was amended to provide for a restricted stock grant of 50,000 shares, with restrictions that lapsed on December 3, 2009, in lieu of the cash bonus for fiscal 2008 that Mr. Bagley would otherwise have been eligible to receive. Replacing Mr. Bagley’s cash bonus potential with a restricted stock grant was in accordance with the Company’s efforts to conserve cash. The Company’s other senior management employees also received restricted stock grants in accordance with these efforts.

Under his new agreement, Mr. Bagley is eligible for reimbursement of reasonable out-of-pocket expenses incurred by him in furtherance of the business and affairs of the Company, including reasonable travel and entertainment expenses, as well as reasonable professional dues.

In connection with entering into the new employment agreement on June 25, 2008, the Company granted Mr. Bagley an award of 60,000 options to purchase the Company’s common stock at a per share exercise price of $2.14, which options vest in three equal annual installments on June 25, 2009, June 25, 2010 and June 25, 2011.

On May 13, 2009, the Company granted to Mr. Bagley options to purchase 100,000 shares of the Company’s common stock at an exercise price of $0.70, which options vest or vested in four equal installments on each of May 13, 2009, August 13, 2009, November 13, 2009, and February 13, 2010.

Director Compensation

Under the Company’s director compensation policy in effect for fiscal 2009, each non-employee director of the Company received a $3,750 quarterly cash retainer paid in arrears plus $2,000 for each Board of Director’s meeting attended by such director. In addition, the chairmen of the Company’s audit committee and compensation committee receive an additional quarterly cash retainer of $2,500 paid in arrears. With the exception of the chairmen of the audit committee and compensation committee, each other non-employee director serving on the Company’s audit committee, compensation committee and corporate governance and nominating committee received a $1,000 cash payment for each committee meeting attended by such director. In addition, the Company’s general practice has been to approve year-end equity incentive grants to non-employee directors in consideration for services provided to the Company as directors during the preceding year.  On December 31, 2009, the Board of Directors awarded each non-employee director 7,500 restricted shares of  the Company’s common stock and an option to purchase 7,500 shares of the Company’s common stock at an exercise price equal to $2.85 per share.  The restricted shares are subject to transfer and forfeiture restrictions that lapse, and the options vest, in two equal annual installments of 3,750 each on December 31, 2010 and 2011. In addition to the year-end equity incentive grants, each non-employee director also received a grant of 30,000 restricted shares of  the Company’s common stock on September 23, 2009. These additional one-time grants were made as part of the Company’s overall personnel retention program and in respect of the considerable additional time and attention that the directors contributed to the Company during 2009 in overseeing the Company’s product development and capital raising endeavors. The transfer and forfeiture restrictions applicable to these grants are scheduled to lapse in their entirety on the one year anniversary of the grant date.

The table below summarizes the compensation paid by the Company to its non-employee directors for the fiscal year ended December 31, 2009.

On March 31, 2010, the Company adopted an amended policy governing director compensation for 2010 and beyond.

	Chair		Member
Audit Committee	$	15,000	$	8,000
Compensation Committee	$	10,000	$	6,000
Corporate Governance and Nominating Committee	$	6,000	$	4,000

The non-executive Lead Director will also receive further annualized cash compensation of $15,000. All cash retainers are paid on a quarterly basis in arrears to non-employee directors that continue to serve as members of the Board on the last business day of each calendar quarter. In addition, at the end of each calendar year (commencing with 2010), each non-employee director will receive annual equity incentive grants comprised of restricted shares of the Company’s common stock and options to purchase shares of the Company’s common stock. These grants, which will vest in their entirety on the one year anniversary of the date of grant, will be in consideration for services to be provided to the Company as directors during the next year. The number of restricted shares and options comprising each grant will be determined by the Board of Directors prior to the end of each calendar year upon recommendation from the compensation committee. Equity awards representing consideration for 2010 service were granted upon the March 31, 2010 amendment to the director compensation policy, such grants being in respect of grants that would have been made had the amended policy been in place on December 31, 2009. Effective upon a director’s initial election to the Board, he or she will receive 25,000 restricted shares of the Company’s common stock and an option to purchase 25,000 shares of the Company’s common stock.  The restricted stock will be subject to transfer and forfeiture restrictions that will lapse on the one year anniversary of the grant date and the stock option will vest in three equal annual installments.

As set forth in its written charter, the compensation committee annually, or more frequently if deemed advisable, reviews director compensation practices and recommends any changes for adoption by the full Board of Directors. As such, the director compensation described above is subject to change at the discretion of the Board of Directors.

Our Board of Directors adopted a Code of Business Conduct and Ethics to be applicable to all officers, directors and employees. The Code of Business Conduct and Ethics is intended to be designed to deter wrong-doing and promote honest and ethical behavior, full, fair, timely, accurate and understandable disclosure, and compliance with applicable laws. The Code of Ethics is available on our website at www.ziopharm.com and a copy may be obtained without charge upon written request to the Company’s President at the Company’s headquarters address.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Related Party Transactions

In consideration for serving as a sub-placement agent in connection with our private placement of common stock and warrants that was completed on September 15, 2009 (the “Offering”), we paid Riverbank Capital Securities, Inc. (“Riverbank”) approximately $185,000 and issued to Riverbank and its designees warrants to purchase a total of 65,843 shares of our common stock at an exercise price of $2.04 per share (the “Placement Warrants”).  Timothy McInerney, who serves as a member of the our Board of Directors, is an officer of Riverbank. Riverbank may allocate or may have allocated to Mr. McInerney a portion of the compensation that it received for serving as a sub-placement agent.  In light of the relationship between Mr. McInerney and Riverbank, Mr. McInerney abstained from voting as a director on matters related to the selection of the placement agents in the Offering and the terms of the Offering were reviewed and approved by a special financing committee of which Mr. McInerney was not a member.

Director Independence

The Board has determined that Dr. Murray Brennan, Mr. George B. Abercrombie, Mr. James A. Cannon, Senator Wyche Fowler, Jr., Mr. Gary S. Fragin, Mr. Timothy McInerney and Dr. Michael Weiser are “independent directors,” as such term is defined in the NASDAQ Stock Market’s Marketplace Rule 5605(a)(2). The Board of Directors has appointed an independent director, Dr. Murray Brennan, to serve as its non-executive Lead Director. The Board has elected to separate the Lead Director function from that of the Chief Executive Officer, who serves as the Company’s principal executive officer, due to a belief that separating these functions, and empowering an independent director to chair the Board meetings, will result in increased Board oversight of management activities.The Board of Directors has a standing audit committee, compensation committee and corporate governance and nominating committee. The current members of the committees are as follows:

Director	Audit			Compensation			Corporate Governance and  Nominating
George B. Abercrombie					X			X
Murray Brennan					X	(Chair)		X
James A. Cannon		X	(Chair)
Gary S, Fragin		X
Wyche Fowler, Jr., J.D.		X						X
Timothy McInerney								X	(Chair)
Michael Weiser, M.D., Ph.D.					X

Item 14. Principal Accountant Fees and Services

Fees Billed to Company by Its Independent Registered Public Accounting Firm

Caturano and Company, P.C. served as the Company’s independent registered public accounting firm for each of the fiscal years ended December 31, 2009 and 2008. The following table presents fees billed by Caturano and Company, P.C. during such years.

	For the Fiscal Year Ended December 31,
	2009		2008
Audit Fees(1)	$	159,291	$	106,136
Audit Releated Fees(2)		-		-
Tax Fees		-		-
All Other Fees		-		-
Total	$	159,291	$	106,136

(1) Represents amounts related to the audit of the Company’s annual financial statements and the review of the Company’s financial statements included in the Company’s quarterly reports on Form 10-Q.

(2) Audit-related fees represent amounts reasonably related to the performance of the audit or review of the Company’s financial statements but are not reported under the Audit Fees category.

18

The audit committee of the Board of Directors has reviewed the services provided by Caturano and Company, P.C. during the fiscal year ended December 31, 2009 and the amounts billed for such services. After consideration, the audit committee has determined that the receipt of these fees by Caturano and Company, P.C. is compatible with the provision of independent audit services. The audit committee has discussed these services and fees with Caturano and Company, P.C. and Company management to determine that they are appropriate under the rules and regulations concerning auditor independence promulgated by the U.S. Securities and Exchange Commission to implement the Sarbanes-Oxley Act of 2002, as well as under guidelines of the American Institute of Certified Public Accountants.

Audit Committee Pre-Approval Policy

The audit committee charter provides that all audit and non-audit accounting services that are permitted to be performed by the Company’s independent registered public accounting firm under applicable rules and regulations must be pre-approved by the audit committee or by designated independent members of the audit committee, other than with respect to de minimis exceptions permitted under Section 202 of the Sarbanes-Oxley Act of 2002. Following adoption of the audit committee charter, all services performed by Caturano & Company, P.C. have been pre-approved in accordance with the charter.

Prior to or as soon as practicable following the beginning of each fiscal year, a description of audit, audit-related, tax, and other services expected to be performed by the independent registered public accounting firm in the following fiscal year is presented to the audit committee for approval. Following such approval, any requests for audit, audit-related, tax, and other services not presented and pre-approved must be submitted to the audit committee for specific pre-approval and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings. However, the authority to grant specific pre-approval between meetings, as necessary, may be delegated to one or more members of the audit committee who are independent directors. In the event such authority is so delegated, the full audit committee must be updated at the next regularly scheduled meeting with respect to any services that were granted specific pre-approval by delegation. During fiscal year 2009, the audit committee has functioned in conformance with these procedures.
