2. Registration Statement and Prospectus

. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-161453) under the Securities Act of 1933, as amended (the “Securities Act”) and the published rules and regulations thereunder (the “Rules and Regulations”) adopted by the Commission, including a base prospectus relating thereto (the “Base Prospectus”), and such amendments and supplements thereto as may have been required to the date of this Agreement. Such registration statement, at any given time, including amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents and information otherwise deemed to be a part thereof or included therein by Rule 430B under the Securities Act or otherwise pursuant to the Rules and Regulations at such time, is herein called the “Registration Statement.” If the Company files an abbreviated registration statement to register additional Units pursuant to Rule 462(b) under the Rules and Regulations (the “462(b) Registration Statement”), then any reference herein to the Registration Statement shall also be deemed to include such 462(b) Registration Statement, as amended from time to time. The Registration Statement at the time it originally became effective is herein called the “Initial Registration Statement.”

The Company proposes to file with the Commission pursuant to Rule 424 under the Securities Act a final prospectus supplement to the Base Prospectus relating to the Units, the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus.” Any preliminary form of Prospectus or prospectus subject to completion which is filed or used in the Offering prior to filing of the Prospectus (including the Base Prospectus as so supplemented) is hereinafter called a “Preliminary Prospectus.”

Unless otherwise stated herein, any reference herein to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the last to occur of the time the Registration Statement became effective with respect to the Underwriters pursuant to Rule 430B under the Securities Act (the “Effective Time”), the date of the Preliminary Prospectus (if any), or the date of the Prospectus, and any reference herein to the terms “amend,” “amendment,” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any document filed under the Exchange Act after the Effective Time, the date of such Preliminary Prospectus or the date of the Prospectus, as the case may be, which is incorporated therein by reference.

(dd) Trading Market; Exchange Act Registration. The Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is included or approved for inclusion on the NASDAQ Capital Market and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act or delisting the Common Stock from the NASDAQ Capital Market nor has the Company received any notification that the Commission, the NASDAQ Capital Market or the Financial Industry Regulatory Authority is contemplating terminating such registration or listing.

The Company agrees to indemnify and hold harmless the Underwriters against any losses, claims, damages or liabilities, joint or several, to which such Underwriters may become subject, under the Securities Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus), any Issuer Free Writing Prospectus or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Common Stock (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) in whole or in part upon any inaccuracy in the representations and warranties of the Company contained herein; or (iii) in whole or in part upon any failure of the Company to perform their respective obligations hereunder or under law, and shall reimburse the Underwriters promptly upon demand for any documented legal fees or other expenses reasonably incurred by the Underwriters in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise reasonably incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and expenses are incurred); provided, however, that with respect to clause (i) above, the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus), any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by the Underwriters, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Underwriters’ Information.

(b) Indemnification of the Company. Each of the Underwriters, severally but not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriters), insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus), any Issuer Free Writing Prospectus or in any Marketing Materials, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430B of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto (including any documents filed under the Exchange Act and deemed to be incorporated by reference into the Prospectus), or any Issuer Free Writing Prospectus or in any Marketing Materials in reliance upon and in conformity with written information furnished to the Company by the Underwriters, specifically for use in the preparation thereof, which information the parties hereto agree is limited to the Underwriters’ Information, and shall reimburse the Company promptly upon demand for any documented legal fees or other expenses reasonably incurred by the Company in connection with investigating, or preparing to defend, or defending against, or appearing as a third party witness in respect of, or otherwise reasonably incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding, as such fees and expenses are incurred.

(c) Notice and Procedures. Promptly after receipt by an indemnified party under Section 6(a) or 6(b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section 6(a) or 6(b), notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party except to the extent such indemnifying party has been materially prejudiced by such failure. In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such Section 6(a) or 6(b) for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, the indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 6(a) or the Underwriters in the case of a claim for indemnification under Section 6(b) or (ii) representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them (which such judgment the indemnified party shall have reasonably concluded in good faith); provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties, and the reasonable and documented expenses of such separate counsel shall be borne by the indemnifying party or parties and reimbursed to the indemnified parties as incurred (in accordance with the provisions of Section 6(a) or 6(b) above, as applicable).

The indemnifying party under this Section 6 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (A) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (B) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Contribution; Limitation on Liability. If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) above, then each indemnifying party shall in lieu of indemnifying such indemnified party contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in Section 6(a) or 6(b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the Offering or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other from the Offering shall be deemed to be in the same proportion as the total net proceeds from the Offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this Section 6(d). The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 6(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this Section 6(d). Notwithstanding the provisions of this Section 6(d), the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Units placed by them and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriters have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 6(d) are several in proportion to the total underwriting discounts and commissions received by the Underwriters and not joint.

(e) Non-Exclusive Remedies. The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriters within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company (including any person who, with his consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Securities Act.

7. Representations and Agreements to Survive Delivery

. The respective indemnities, covenants, agreements, representations, warranties and other statements of the Company and the Underwriters, as set forth in this Agreement or made by them respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters, the Company, or any person controlling any of them and shall survive delivery of and payment for the Units. Notwithstanding any termination of this Agreement, including without limitation any termination pursuant to Section 9, the indemnity and contribution agreements contained in Section 6 and the covenants, representations, warranties set forth in this Agreement shall not terminate and shall remain in full force and effect at all times.

8. Information Furnished by Underwriters

. The parties hereto acknowledge and agree that, for all purposes of this Agreement, the “Underwriters’ Information” consists solely of the statements contained in the third, sixth and ninth through fourteenth paragraphs under the heading “Underwriting” in the Prospectus.

9. Termination of this Agreement.

(a) The Underwriters shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the Closing Date, without liability on the part of the Underwriters to the Company, if (i) prior to delivery and payment for the Units (A) trading in securities generally shall have been suspended on or by the New York Stock Exchange, the NYSE Amex, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market or in the over the counter market (each, a “Trading Market”), (B) trading in the Common Stock of the Company shall have been suspended on any exchange, in the over-the-counter market or by the Commission, (C) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities or a material disruption shall have occurred in commercial banking or securities settlement or clearance services in the United States, (D) there shall have occurred any outbreak or material escalation of hostilities or acts of terrorism involving the United States or there shall have been a declaration by the United States of a national emergency or war, (E) there shall have occurred any other calamity or crisis or any material change in general economic, political or financial conditions in the United States or elsewhere, if the effect of any such event specified in clause (D) or (E), in the judgment of the Representative, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Units on the Closing Date on the terms and in the manner contemplated by this Agreement, the Time of Sale Disclosure Package and the Prospectus, (ii) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Time of Sale Disclosure Package or incorporated by reference therein, there has been any Material Adverse Change or the Company or any Subsidiary shall have sustained a loss or interference with its business by strike, fire, flood, earthquake, accident or other calamity, whether or not covered by insurance, in each case which is not described in the Time of Sale Disclosure Package or the Prospectus and is of such character that in the judgment of the Representative would, individually or in the aggregate, result in a Material Adverse Change and which would, in the judgment of the Representative, make it impracticable or inadvisable to proceed with the offering or the delivery of the Units on the terms and in the manner contemplated in this Agreement, the Time of Sale Disclosure Package and the Prospectus, (iii) the Company shall have failed, refused or been unable to comply with the terms or perform any agreement or obligation of this Agreement, other than by reason of a default by the Underwriters, or (iv) any condition of the Underwriters’ obligations hereunder is not fulfilled. Any such termination shall be without liability of any party to any other party except that the Company will reimburse the Underwriters for all of their out-of-pocket expenses actually incurred by them in connection with the Offering, and that the provisions of Section 6, and Section 14 hereof shall at all times be effective notwithstanding such termination.

(b) If the Underwriters elect to terminate this Agreement as provided in this Section 9, the Company shall be notified promptly by the Underwriters by telephone, confirmed by letter.

10. Substitution of Underwriters. If any Underwriter shall default in its obligation to purchase on the Closing Date the Units agreed to be purchased hereunder on such Closing Date, the Representative shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase such Units on the terms contained herein. If, however, the Representative shall not have completed such arrangements within such 36-hour period, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Underwriters to purchase such Units on such terms. If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of Units which remains unpurchased on such Closing Date does not exceed one-eleventh of the aggregate number of all the Units that all the Underwriters are obligated to purchase on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Units which such Underwriter agreed to purchase hereunder at such date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. In any such case, either the Representative or the Company shall have the right to postpone the Closing Date for a period of not more than seven days in order to effect any necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or Prospectus or any other documents), and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the Company and the Underwriters and their counsel may thereby be made necessary.

If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of such Units which remains unpurchased exceeds 10% of the aggregate number of all the Units to be purchased at such date, then this Agreement shall terminate, without liability on the part of any non-defaulting Underwriter to the Company, and without liability on the part of the, except as provided in Sections 4(h), 6 and 9. The provisions of this Section 10 shall not in any way affect the liability of any defaulting Underwriter to the Company or the nondefaulting Underwriters arising out of such default. The term "Underwriter" as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Units.

San Francisco, CA 94111

Re:

Public Offering of Securities

Ladies and Gentlemen:

The undersigned understands that you, as representative (the “Representative”) of the several underwriters (the “Underwriters”), propose to enter into the Underwriting Agreement (the “Underwriting Agreement”) with ZIOPHARM Oncology, Inc., a Delaware corporation (the “Company”), providing for the offering (the “Offering”) of shares of common stock, $0.001 par value per share (the “Common Stock”), warrants and other securities, if applicable, of the Company. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In order to induce the Underwriters to enter in to the Underwriting Agreement, the undersigned hereby agrees that for a period (the “Lock-Up Period”) of ninety (90) days following the date of the final prospectus filed by the Company with the Securities and Exchange Commission in connection with such offering, the undersigned will not, without the prior written consent of the Representative, directly or indirectly, (1) offer for sale; sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction or device which is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock or any securities convertible into or exchangeable for Common Stock, or sell or grant any options, rights or warrants with respect to any shares of Common Stock or securities convertible into or exchangeable for Common Stock other than (i) the grant of options or other equity based compensation pursuant to plans existing as of the date of this Lock-Up Agreement, (ii) the disposition of securities to the Company pursuant to a cashless exercise or tax withholding feature contained in an option or other equity award outstanding as of the date of this Lock-Up Agreement, and (iii) the exercise of options and the disposition of Common Stock acquired upon exercise of options expiring on or before the end of the Lock-Up Period, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks or ownership of the Common Stock, regardless of whether such transaction described herein is to be settled by delivery of the Common Stock or other securities, in cash or otherwise; provided, however, the foregoing restriction shall not apply to (i) securities required to be issued pursuant to contractual obligations of the Company in effect as of the date of this Lock-Up Agreement or (ii) equity securities issued pursuant to employee benefit or purchase plans in effect as of the date of this Lock-Up Agreement or pursuant to bona fide employee benefit or purchase plans established during the Lock-Up Period. Notwithstanding the foregoing restrictions, the undersigned shall be permitted to sell up to an aggregate of 6,000 shares of Common Stock solely for the purpose of facilitating payment of the undersigned’s tax liabilities; provided, however, that no such sale shall occur prior to January 1, 2010.

A-1

None of the restrictions set forth in this Lock-Up Agreement shall apply to Common Stock acquired in open market transactions.

For the purpose of allowing you to comply with FINRA Rule 2711(f)(4), if (a) the Company issues an earnings release or material news or a material event relating to the Company occurs during the last seventeen (17) days of the lock-up period, or (b) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the eighteen (18)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event (the term “Lock-Up Period” shall be deemed to include any extension pursuant to this paragraph).

The undersigned hereby acknowledges and agrees that written notice of any extension of the Lock-Up Period pursuant to the previous paragraph will be delivered by the Representative to the Company (in accordance with the notice provision in the Underwriting Agreement) and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as may have been extended pursuant to the previous paragraph) has expired.

The foregoing restrictions are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a sale or disposition of the Common Stock even if such Common Stock would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put option or put equivalent position or call option or call equivalent position) with respect to any of the Common Stock or with respect to any security that includes, relates to, or derives any significant part of its value from such Common Stock.

The undersigned xxxxxx agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent against the transfer of securities of the Company held by the undersigned during the Lock-Up Period (as may have been extended pursuant hereto), except in compliance with this Lock-Up Agreement.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the securities to be sold thereunder, the undersigned shall be released from all obligations under this Lock-Up Agreement.

A-2

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. This Lock-Up Agreement is irrevocable and all authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

2. The Company is in good standing as a foreign corporation and is duly qualified to do business in the jurisdictions listed opposite its name on a schedule thereto.

3. The Company has the requisite corporate power and authority necessary to own or lease, as the case may be and operate its properties, to conduct its business as currently being carried on and as it is described in the Registration Statement, the Time of Sale Disclosure Package and the Prospectus, to execute and deliver the Agreement, and to issue, sell and deliver the Units as contemplated by the Agreement.

The Warrants have been duly authorized and, when issued, delivered and paid for in accordance with the terms of the Agreement and the Warrants, will be valid and binding. Assuming a sufficient number of authorized but unissued shares of Common Stock are available for issuance when the Warrants are exercised, the Warrant Shares, when and if issued upon exercise of the Warrants and paid for in accordance with the terms of the Warrants, will be validly issued, fully paid and non-assessable.

7. Except as set forth in the Registration Statement, in the Time of Sale Disclosure Package or the Prospectus, to such counsel’s knowledge, neither the filing of the Registration Statement nor the offering or sale of the Units as contemplated by the Agreement gives rise to any rights for or relating to the registration of any shares of Common Stock or other securities of the Company, except for rights which have been waived or satisfied.

9. The Agreement has been duly authorized by all necessary corporate action on the part of the Company and have been duly executed and delivered by the Company and each constitutes a valid and binding agreement of the Company, and is enforceable against the Company in accordance with the terms thereof, except as the enforceability thereof may be subject to or limited by (a) bankruptcy, insolvency, reorganization, arrangement, moratorium, or other similar laws relating to or affecting the rights of creditors, and (b) general equitable principles, regardless of whether the issue of enforceability is considered in a proceeding in equity or law.

10. The execution and delivery of the Agreement by the Company and the issuance and sale by the Company of the Units and the consummation by the Company of the transactions contemplated by the Agreement to be consummated by the Company do not and will not result in any breach or a default under (nor constitute any event that with notice, lapse of time or both would result in any breach or default under), or conflict with (a) any provisions of the certificate of incorporation or by-laws of the Company, (b) any provision of any material license, permit, indenture, mortgage, deed of trust, note, bank loan or credit agreement or other evidence of indebtedness, license, lease, contract or other agreement or instrument, in each case filed as an exhibit to the Company’s most recently filed Annual Report on Form 10-K or subsequently filed as an exhibit to any other report or registration statement, (c) any U.S. federal or state law, regulation or rule that, in such counsel’s experience, is generally applicable to transactions of the nature of those contemplated by the Agreement and is applicable to the Company, or the Delaware General Corporation Law (other than the state securities or blue sky laws and the rules of FINRA governing underwriters compensation, as to which such counsel expresses no opinion), or (d) any decree, judgment or order known to such counsel to be applicable to the Company.

11. The Company is not required to register as an “investment company” as defined in the Investment Company Act of 1940, as amended.

12. No approval, authorization, consent or order or filing with any U.S. federal, state court or governmental or regulatory agency or body in the United States having jurisdiction over the Company, or approval of the shareholders of the Company, is required to be obtained or made by the Company for the consummation by the Company of the transactions contemplated by the Agreement, except for such as have been duly obtained or made, including without limitation, registration of the Shares and Warrant Shares under the Securities Act and of the Common Stock under the Exchange Act, or such as may be required under (x) the state securities or blue sky laws of the various states or (y) the bylaws or rules and regulations of FINRA, as to which such counsel expresses no opinion.

C-2

13. To such counsel’s knowledge, there is not pending or threatened in writing any action, suit or proceeding, inquiry or investigation to which the Company is a party, or to which the property of the Company is subject, before or brought by any court or governmental agency or body that explicitly places in question the validity or enforceability of, or seeks to enjoin the performance of, the Agreement or which is of a character that is required to be disclosed in the Registration Statement or the Prospectus and is not so disclosed.

Form of Warrant

ZIOPHARM ONCOLOGY, INC.

WARRANT TO PURCHASE COMMON STOCK


Warrant No. 2009PS1-[ ]		Original Issue Date: [ ], 2009

ZIOPHARM Oncology, Inc., a Delaware corporation (the “Company”), hereby certifies that, for value received, [ ] or its permitted registered assigns (the “Holder”), is entitled to purchase from the Company up to a total of [ ] shares of common stock, $0.001 par value (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price per share equal to $[ ] (as adjusted from time to time as provided in Section 8 herein, the “Exercise Price”), at any time and from time to time from on or after the date hereof (the “Trigger Date”) and through and including 5:30 P.M., New York City time, on [ ], 2014 (the “Expiration Date”), and subject to the following terms and conditions:

This Warrant (this “Warrant”) is being issued pursuant to that certain Underwriting Agreement, dated as of [ ], 2009, by and between the Company and the Representative of the several underwriters identified therein (the “Purchase Agreement”) and pursuant to the Company’s Registration Statement on Form S-3 (SEC File No. 333-161453) (the “Registration Statement”).

1. Registration of Warrants. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder (which shall include the initial Holder or, as the case may be, any registered assignee to which this Warrant is permissibly assigned hereunder) from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

2. Registration of Transfers. Subject to compliance with applicable securities laws, the Company shall register the transfer of all or any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached as Schedule 2 hereto duly completed and signed, to the Company’s transfer agent or to the Company at its address specified in the Purchase Agreement. Upon any such registration or transfer, a new warrant to purchase Common Stock in substantially the form of this Warrant (any such new warrant, a “New Warrant”) evidencing the portion of this Warrant so transferred shall be issued to the transferee, and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a Holder of a Warrant.

3. Exercise and Duration of Warrants.

(a) Subject to compliance with applicable securities laws, all or any part of this Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the Trigger Date and through and including 5:30 P.M. New York City time on the Expiration Date. At 5:30 P.M., New York City time, on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value and this Warrant shall be terminated and no longer outstanding.

(b) The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule 1 hereto (the “Exercise Notice”), appropriately completed and duly signed, and (ii) payment of the Exercise Price in immediately available funds for the number of Warrant Shares as to which this Warrant is being exercised (or by cashless exercise, if permitted), and the date such items are delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise Date.” The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares.

4. Delivery of Warrant Shares.

(a) Upon exercise of this Warrant, the Company shall promptly (but in no event later than three Trading Days after the Exercise Date) issue or cause to be issued the Warrant Shares issuable upon such exercise, and the Company cause such Warrant Shares to be delivered by the Company’s transfer agent to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system if the Company is then a participant in such system, or otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise. This Warrant shall be deemed to have been exercised on the first date on which all of the foregoing have been delivered to the Company. The Holder, or any “Person” (which for purposes of this Warrant shall include any individual, limited liability company, partnership, joint venture, corporation, trust, unincorporated organization or any other entity, government, including any agency or department thereof) permissibly so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of the Exercise Date. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant. To the extent permitted by applicable law, the Company’s obligations to issue and deliver Warrant Shares upon exercise of this Warrant and in accordance with the terms hereof are unconditional, and the Holder shall, subject to the following proviso, have the right to pursue any remedies available to it hereunder, at law or in equity with respect to the Company’s failure to do so; provided, however, that notwithstanding anything to the contrary in this Warrant or in the Purchase Agreement, and except as provided pursuant to Section 4(b), if the Company is for any reason unable to deliver Warrant Shares upon exercise of this Warrant as required pursuant to the terms hereof, the Company shall have no obligation to pay to the Holder cash or other consideration or otherwise “net cash settle” this Warrant.

(b) If (1) a certificate representing the Warrant Shares is not delivered to the Holder within three (3) Trading Days of the due exercise of this Warrant by the Holder and (2) prior to the time such certificate is received by the Holder, the Holder, or any third party on behalf of the Holder or for the Holder’s account, purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares represented by such certificate (a “Buy-In”), then the Company shall pay in cash to the Holder (for costs incurred either directly by such Holder or on behalf of a third party) the amount by which the total purchase price paid for Common Stock as a result of the Buy-In (including brokerage commissions, if any) exceeds the proceeds received by such Holder as a result of the sale to which such Buy-In relates. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.

5. Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense in respect of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder or an affiliate thereof. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

6. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction (in such case) and, in each case, a customary and reasonable indemnity (which shall not include a surety bond), if requested. Applicants for a New Warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

7. Reservation of Warrant Shares. The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 8). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable. The Company will take all such action as may be necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Shares may be listed.

8. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 8.

(a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides its outstanding shares of Common Stock into a larger number of shares, or (iii) combines its outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately before such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(b) Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation of the Company with or into another Person, in which the shareholders of the Company as of immediately prior to the transaction own less than a majority of the outstanding stock of the surviving entity, (ii) the Company effects any sale of all or substantially all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which all or substantially all of the holders of Common Stock are permitted to tender or exchange their shares for other securities, cash or property and would result in the shareholders of the Company immediately prior to such tender offer or exchange offer owning less than a majority of the outstanding stock after such tender offer or exchange offer, (iv) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 8(a) above), (v) any transaction where the Company consummates a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than the 50% of the outstanding Common Stock or (vi) any transaction where any "person" or "group" (as these terms are used for purposes of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is or shall become the "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended), directly or indirectly, of 50% aggregate ordinary voting power represented by issued and outstanding Common Stock (in any such case, a “Fundamental Transaction”), then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate Consideration”). Notwithstanding the foregoing, in the event of a Fundamental Transaction, at the request of the Holder delivered before the 90th day after such Fundamental Transaction, the Company (or the surviving entity) shall purchase this Warrant from the Holder by paying to the Holder, within five Business Days after such request (or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of such Fundamental Transaction. The Company shall not effect any such Fundamental Transaction unless prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Holder, such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to purchase and/or receive (as the case may be), and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction. As used herein, “Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg Financial Markets determined as of the day of the closing of the applicable Fundamental Transaction for pricing purposes and reflecting (i) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of this Warrant as of such date of request, (ii) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg Financial Markets as of the day immediately following the public announcement of the applicable Fundamental Transaction, (iii) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non cash consideration, if any, being offered in the Fundamental Transaction and (iv) a 365 day annualization factor.

(c) Certain Issuances of Common Securities. If, any time prior to the four year anniversary of the Original Issue Date of this Warrant, the Company shall (x) sell or issue shares of its Common Stock (other than a dividend or distribution of Common Stock referred to in Section (a) above), (y) issue rights, options or warrants to subscribe for or purchase shares of Common Stock or (z) issue or sell other rights for shares of Common Stock or securities convertible or exchangeable into shares of Common Stock (collectively, any such stock, rights, options or warrants being referred to as “Common Securities”), at a price per share less than the then applicable Exercise Price, then in each such case the Exercise Price in effect immediately prior to the issuance of such Common Securities shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the date of issuance of the Common Securities by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to the issuance of the Common Securities plus the number of shares of Common Stock which the aggregate consideration received for the issuance of the Common Securities would purchase at such Exercise Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately after the issuance of the Common Securities (after giving effect to the full exercise, conversion or exchange, as applicable, of such Common Securities). The adjustment provided for in this Section (ii) shall be made successively whenever any such Common Securities are issued (provided, however, that, except as provided below, no further adjustments in the Exercise Price shall be made upon the subsequent exercise, conversion or exchange, as applicable of such Common Securities pursuant to the terms of such Common Securities) and shall become effective immediately after such issuance; provided, however, that the Exercise Price shall in no event be adjusted pursuant to this paragraph (c) to amount less than $0.50 per share (which $0.50 amount shall be adjusted appropriately based on any adjustments pursuant to paragraph (a) of this Section). In determining whether any Common Securities entitle the holders of the Common Stock to subscribe for or purchase shares of Common Stock at less than the Exercise Price, and in determining the aggregate offering price of the shares of Common Stock so offered, there shall be taken into account any consideration received by the Company for such Common Securities, any consideration required to be paid upon the exercise, conversion, or exchange, as applicable, of such Common Securities and the fair market value (as determined in good faith by the Company’s board of directors) of all such consideration (if other than cash). Upon the expiration or termination of the right to exercise, convert or exchange any Common Securities, any adjustment to the Exercise Price which was made upon the issuance of such Common Securities, and any subsequent adjustments based thereon, shall be recomputed to reflect the issuance of only the number of shares of Common Stock actually issued upon the exercise, conversion or exchange of such Common Securities and the actual consideration received therefor (as determined herein). For purposes of this Section 8(c), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company or by any subsidiary of the Company. Notwithstanding the foregoing, no adjustment will be made under this Section 8(c) in respect of: (i) the issuance of securities upon the exercise or conversion of any Common Stock, or stock or securities directly or indirectly convertible into or exercisable or exchangeable for Common Stock (“Convertible Securities”), issued by the Company prior to the date hereof; provided, however, that neither the conversion price, exercise price nor number of shares issuable under such Convertible Securities (excluding any Convertible Securities covered by clause (ii) below) is amended, modified or changed after the Original Issuance Date of this Warrant other than pursuant to the provisions of such Convertible Securities as they exist as of such date, (ii) the grant of options, warrants, Common Stock or other Convertible Securities (but not including any amendments to such instruments) to employees, officers, directors of the Company under any duly authorized Company stock option, restricted stock plan or stock purchase plan whether now existing or hereafter approved by the Company and its stockholders in the future, and the issuance of Common Stock in respect thereof, or (iii) the issuance of securities in a transaction described in paragraphs (a) and (b) of this Section (collectively, “Excluded Issuances”).

(d) Rights Upon Distribution of Assets. If the Company, at any time while this Warrant is outstanding, shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, evidence of indebtedness, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (excluding those referred to in Section 8(a)) (a “Distribution”), then in each such case the Company shall simultaneously distribute such Distribution pro rata to the Holders of Warrants on the record date or date of effectiveness, as the case may be, fixed for determining the holders of Common Stock entitled to participate in such Distribution, in an amount equal to the amount that each Holder would have been entitled to receive had its Warrants been exercised in full (without regard to any limitations on the exercise of the Warrants) for Warrant Shares immediately prior to the time for determination of the holders of Common Stock entitled to participate in such distribution.

(e) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) or (c) of this Section, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

(f) Calculations. All calculations under this Section 8 shall be made to the nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the sale or issuance of any such shares shall be considered an issue or sale of Common Stock.

(g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 8, the Company at its expense will, at the written request of the Holder, compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

9. Payment of Exercise Price. The Holder shall pay the Exercise Price in immediately available funds; provided, however, that if, on any Exercise Date a registration statement registering the issuance of the Warrant Shares under the Securities Act of 1933, as amended (the “Securities Act”) is not effective, the Holder may, in its sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

	X = Y [(A-B)/A]

where:

	X = the number of Warrant Shares to be issued to the Holder.

	Y = the total number of Warrant Shares with respect to which this Warrant is being exercised.

	A = the average of the Closing Sale Prices of the shares of Common Stock (as reported by Bloomberg Financial Markets) for the five Trading Days ending on the date immediately preceding the Exercise Date.

	B = the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

For purposes of this Warrant, “Closing Sale Price” means, for any security as of any date, the last trade price for such security on the principal securities exchange or trading market for such security, as reported by Bloomberg Financial Markets, or, if such exchange or trading market begins to operate on an extended hours basis and does not designate the last trade price, then the last trade price of such security prior to 4:00:00 p.m., New York Time, as reported by Bloomberg Financial Markets, or if the foregoing do not apply, the last trade price of such security in the over-the-counter market on the electronic bulletin board for such security as reported by Bloomberg Financial Markets, or, if no last trade price is reported for such security by Bloomberg Financial Markets, the average of the bid prices, or the ask prices, respectively, of any market makers for such security as reported in the "pink sheets" by Pink Sheets LLC. If the Closing Sale Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Sale Price of such security on such date shall be the fair market value as mutually determined by the Company and the Holder. If the Company and the Holder are unable to agree upon the fair market value of such security, then the Company shall, within two business days submit via facsimile (a) the disputed determination of the Warrant Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company's independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten business days from the time it receives the disputed determinations or calculations. Such investment bank's or accountant's determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. All such determinations to be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during the applicable calculation period

For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Purchase Agreement (provided that the Commission continues to take the position that such treatment is proper at the time of such exercise).

10. Limitations on Exercise. Notwithstanding anything to the contrary contained herein, the Holder shall not have the right to exercise this Warrant to the extent that, following such exercise, the total number of shares of Common Stock then beneficially owned by the Holder and its affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, would exceed 9.99% (the “Maximum Percentage”) of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. The Company’s obligation to issue shares of Common Stock in excess of the limitation referred to in this Section shall be suspended (and, except as provided below, shall not terminate or expire notwithstanding any contrary provisions hereof) until such time, if any, as such shares of Common Stock may be issued in compliance with such limitation; provided, that, if, as of 5:30 p.m., New York City time, on the Expiration Date, the Company has not received written notice that the shares of Common Stock may be issued in compliance with such limitation, the Company’s obligation to issue such shares shall terminate. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 19.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase will only apply to the Holder and not to any other holder of Warrants.

11. Purchase Rights. In addition to any adjustments pursuant to Section 8 above, if at any time the Company grants, issues or sells any options, convertible securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

12. No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares which would otherwise be issuable, subject to Section 10, the number of Warrant Shares to be issued shall be rounded up to the next whole number.

13. Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in the Purchase Agreement prior to 5:30 p.m. (New York City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in the Purchase Agreement on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service specifying next business day delivery, or (iv) upon actual receipt by the party to whom such notice is required to be given, if by hand delivery. The address and facsimile number of a party for such notices or communications shall be as set forth in the Purchase Agreement unless changed by such party by two Trading Days’ prior notice to the other party in accordance with this Section 13.

14. Warrant Agent. The Company shall serve as warrant agent under this Warrant. Upon thirty (30) days’ notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register.

15. Miscellaneous.
