After the Effective Time, each holder of certificate(s) theretofore evidencing outstanding shares of ZIOPHARM Stock (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2) shall, upon surrender of such certificate(s) to the registrar or transfer agent for EasyWeb Common Stock, be entitled to receive certificates representing the number of whole shares of EasyWeb Common Stock into which shares of ZIOPHARM Stock

7

theretofore represented by the certificates so surrendered shall have been converted as provided in Section 2.2(a) hereof.  EasyWeb shall not be obligated to deliver certificates representing shares of EasyWeb Common Stock, to which any holder of shares of ZIOPHARM Stock is entitled, until such holder surrenders the certificate(s) representing such ZIOPHARM Stock.  Upon surrender, each certificate evidencing ZIOPHARM Stock shall be canceled.  If there is a transfer of ZIOPHARM Stock ownership which is not registered in the transfer records of ZIOPHARM, a certificate representing the proper number of shares of EasyWeb Common Stock may be issued to a Person other than the Person in whose name the certificate so surrendered is registered if: (x) upon presentation to the Secretary of EasyWeb, such certificate shall be properly endorsed or otherwise be in proper form for transfer, (y) the Person requesting such transfer shall pay any transfer or other taxes required by reason of the issuance of shares of or certificates representing shares of EasyWeb Common Stock to a Person other than the registered holder of such certificate or establish to the reasonable satisfaction of EasyWeb that such tax has been paid or is not applicable, and (z) the issuance of such shares of or certificates representing shares of EasyWeb Common Stock shall not, in the sole discretion of EasyWeb, violate the requirements of Section 4(2) of the Securities Act with respect to the private placement of EasyWeb Common Stock that will result from the Merger.

NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS IN EFFECT THEREUNDER AND ALL APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS (SUCH FEDERAL AND STATE LAWS, THE “SECURITIES LAWS”) OR (B) IF THE COMPANY HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL FOR THE HOLDER, WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT FROM THE REGISTRATION OR SIMILAR REQUIREMENTS OF THE SECURITIES LAWS.

(c)

In the event any certificate for shares of ZIOPHARM Stock shall have been lost, stolen or destroyed, EasyWeb shall issue in exchange for such lost, stolen or destroyed certificate, upon the making of a sworn affidavit of that fact by the holder thereof, one or more certificates representing such shares of EasyWeb Common Stock as provided herein; provided, however , that EasyWeb, in its discretion and as a condition precedent to the issuance of such certificates, may require the holder of the shares represented by such lost, stolen or destroyed

certificate to deliver a bond in such sum as it may direct as indemnity against any claim that may be made against EasyWeb or any other party with respect to the certificate alleged to have been lost, stolen or destroyed.

(b)

Any payments in respect of Dissenting Shares will be deemed made by the Surviving Company.

2.6

Stock Options .

(a)

At the Effective Time, each outstanding ZIOPHARM Stock Option shall be assumed by EasyWeb and shall thereafter represent an option, warrant or other right, as applicable, to purchase a number of shares of EasyWeb Common Stock (at an exercise price adjusted to reflect to the Exchange Ratio) equal to the number of shares of EasyWeb Common Stock that the holder thereof would have been entitled to receive in the Merger had such holder of such ZIOPHARM Stock Option exercised such option, warrant or other right in full immediately prior to the Effective Time (whether or not vested at the Effective Time).  EasyWeb shall take appropriate action to provide for the assumption of the ZIOPHARM Stock Options that represent stock options granted under ZIOPHARM’s 2003 Stock Option Plan so that, at the Effective Time, each of such then outstanding ZIOPHARM Stock Option shall by virtue of the Merger, and without any further action on the part of any holder thereof, be assumed by EasyWeb under the same terms and conditions as those contained in ZIOPHARM’s 2003 Stock Option Plan.  If the foregoing calculation results in an option, warrant or other right being exercisable for a fraction of a share of EasyWeb Common Stock, then the number of shares of EasyWeb Common Stock subject to such option, warrant or other right shall be rounded down to the nearest whole number of shares.  The term, exercisability, vesting schedule, method of exercise, status as an “ incentive stock option ” under Section 422 of the Code, if applicable, and all other terms and conditions of ZIOPHARM Stock Options being assumed by EasyWeb will, to the extent permitted by law and otherwise reasonably practicable, be unchanged.  If applicable, continuous employment

9

with ZIOPHARM shall be credited to the optionee for purposes of determining the vesting of the number of shares of EasyWeb Common Stock subject to exercise under the optionee’s assumed ZIOPHARM Stock Option after the Effective Time.  

(b)

Prior to the Effective Time, ZIOPHARM shall use its best efforts to (i) obtain any consents from holders of ZIOPHARM Stock Options and (ii) make any amendments to the terms of such stock option, warrant or other right or compensation plans or arrangements that are necessary to give effect to the transactions contemplated by Section 2.6(a).

(c)

Except as set forth on Schedule 2.6(c), prior to the Effective Time, EasyWeb shall terminate all EasyWeb Stock Options outstanding prior to the Effective Time as soon as possible without violating the terms of any plan pursuant to which such options were granted.  EasyWeb shall not grant any EasyWeb Stock Option or any other option, warrant or right to acquire EasyWeb Common Stock or establish any other such stock option or purchase plan on or after the date of this Agreement.

(d)

EasyWeb shall take all corporate action necessary to reserve for issuance a sufficient number of shares of EasyWeb Common Stock for delivery upon exercise of all ZIOPHARM Stock Options assumed pursuant to the terms set forth in this Section 2.6.  EasyWeb shall cause the shares of EasyWeb Common Stock issuable upon exercise of the assumed ZIOPHARM Stock Options that represent stock options issued under the ZIOPHARM 2003 Stock Option Plan to be registered, or to be issued pursuant to a then-effective registration statement, no later than 90 days after the Effective Time (or such longer time as may be prescribed by applicable law or regulation) on Form S-8 (or any successor form thereto) promulgated by the SEC and shall use its best efforts to maintain the effectiveness of such registration statement or registration statements for so long as such assumed ZIOPHARM Stock Options remain outstanding.

34

governmental authority to permit all such Registrable Securities that have been issued to such Holder to be sold or otherwise disposed of, and will maintain such compliance with each such federal and state law and regulation of any governmental authority for the period necessary for such Holder to promptly effect the proposed sale or other disposition.

EasyWeb and ZIOPHARM acknowledge and agree that the holders of ZIOPHARM Series A Preferred Stock have certain demand and piggy-back registration rights granted pursuant to the subscription agreements executed and delivered in connection with ZIOPHARM’s offering and sale of ZIOPHARM Series A Preferred Stock, which rights, after the Merger, shall apply to their shares of EasyWeb Common Stock received in exchange therefor.

5.12

Notification of Certain Matters .   At or prior to the Effective Time, each party shall give prompt notice to the other party of (i) the occurrence or failure to occur of any event or the discovery of any information, which occurrence, failure or discovery would be likely to cause any representation or warranty on its part contained in this Agreement to be untrue, inaccurate or incomplete after the date hereof in any material respect or, in the case of any representation or warranty given as of a specific date, would be likely to cause any such representation or warranty on its part contained in this Agreement to be untrue, inaccurate or incomplete in any material respect as of such specific date, and (ii) any material failure of such party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder.

5.13

35

connection with the foregoing.  None of the information supplied or to be supplied by EasyWeb or ZIOPHARM for inclusion or incorporation by reference in the Information Statement will, at the time the Information Statement is first published, sent or given to holders of the ZIOPHARM Stock, and at any time it is amended or supplemented, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.  If any of the parties hereto becomes aware prior to the Effective Time of any information furnished by it that would cause any of the statements in the Information Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, it will promptly inform the other parties hereto and take the necessary steps to correct the Information Statement.

5.14
