This Amendment No. 1 (the “Amendment”) amends and supplements the Statement on Schedule 13D, dated January 12, 2011 and filed on January 20, 2011 (the “Original Schedule 13D”), relating to the Common Stock, par value $0.001 per share (the “Common Stock”), of ZIOPHARM Oncology, Inc., a Delaware corporation (the “Company”). Mr. Randal J. Kirk (“Mr. Kirk”) and Intrexon Corporation, a Virginia corporation (“Intrexon” and, together with Mr. Kirk, the “Reporting Persons”), are filing this Amendment to disclose the acquisition by Intrexon of 1,910,000 shares of Common Stock in a public offering conducted by the Company (the “Offering”). Mr. Kirk could be deemed to have indirect beneficial ownership of the shares of Common Stock directly beneficially owned by Intrexon.
Except as set forth below, there are no changes to the information set forth in the Original Schedule 13D.
| CUSIP No. 89365K206 | Page 5 of 7 |
| Item 3. | Source and Amount of Funds or Other Consideration. |
Item 3 of the Original Schedule 13D is hereby amended and supplemented as follows:
On February 1, 2011, the Company and Intrexon entered into an amendment (the “Amendment”) to the Stock Purchase Agreement (the “Stock Purchase Agreement”) dated January 6, 2011, which amendment is included as Exhibit 3 hereto. Under the Stock Purchase Agreement, if requested by the Company and subject to certain restrictions and limitations, Intrexon has agreed to purchase securities in conjunction with future securities offerings of the Company that constitute “Qualified Financings,” subject to an aggregate equity purchase commitment of $50,000,000. Reference is made to the description of the Stock Purchase Agreement included as Exhibit 2 hereto. Under the Amendment, the parties agreed that in the event that Intrexon voluntarily elects to purchase securities in a Qualified Financ ing for which the Company does not request that Intrexon participate, the aggregate purchase price paid by Intrexon for such securities shall be applied against and reduce the then remaining maximum amount of Intrexon’s $50,000,000 aggregate equity purchase commitment. The foregoing descriptions of the Stock Purchase Agreement and the Amendment are qualified in their entirety by reference to such agreements, which are incorporated herein by reference.
| Item 5. | Interest in Securities of the Issuer. |
Items 5(a) and (b) of the Original Schedule 13D are hereby amended and restated to read in its entirety as follows:
(a) and (b) See Items 11 and 13 of the cover pages to this Statement for the aggregate number of shares and percentage of issued and outstanding shares of Common Stock of the Company owned by the Reporting Persons. The percentage ownership is calculated based on 48,524,704 shares of Common Stock issued and outstanding as of the closing of the purchase of the Purchase Shares and the First Tranche Shares pursuant to the Stock Purchase Agreement on January 12, 2011, increased by (i) the 6,063,161 shares constituting the Purchase Shares and the First Tranche Shares, (ii) the 25,000 shares of restricted stock issued to Mr. Kirk in connection with his election to the Company’s Board of Directors and (iii) the 11,040,000 shares issued in the Offering, including the overallotment option.
