ZIOPHARM, Inc. and EasyWeb, Inc. Merge to Form ZIOPHARM Oncology, Inc.

New York, NY and Englewood, CO - September 15, 2005 - ZIOPHARM, Inc. (private) and EasyWeb, Inc. (OTC Bulletin Board: ESWB.OB) today announced that they have completed the previously announced merger of the two companies. The Company's common stock trades on the OTC Bulletin Board under the symbol "ESWB.OB" until a new ticker symbol has been issued and announced. In connection with the merger, the combined company has changed its name to ZIOPHARM Oncology, Inc.

Jonathan Lewis, M.D., Ph.D. will serve as Chief Executive Officer and as a Board member of ZIOPHARM Oncology, Inc. along with the remainder of the former Board of Directors of ZIOPHARM, Inc.

"Given our stage of development with two products in phase I trials, it is the appropriate time for the company to be public," commented Dr. Lewis. "We are excited to leverage the strength of the new public company for continued development of our current pipeline and for in-licensing additional product candidates."

The Company is currently in U.S. phase I studies for two product candidates known as ZIO-101 and ZIO-201.

ZIO-101,subject of an issued U.S. patent and applications internationally, is the first of a new class of organic arsenicals that are potentially safer and more active for cancer treatment than approved inorganic arsenicals. The Company initiated phase I studies in adults with diverse hematologic cancers in April 2005, and a parallel phase I study in adults and children with solid tumors in May 2005. The Company is planning for an additional phase I/II trial in patients with advanced myeloma.

ZIO-201, subject of U.S. and international patent applications, is a proprietary formulation of isophosphoramide mustard, the active metabolite of ifosfamide. Ifosfamide is an alkylating drug used to treat diverse cancers including testicular cancer, bone and soft-tissue sarcoma, cervical, breast and lung cancers. A phase I clinical trial is being conducted at two centers in patients with advanced cancers. The Company expects this trial to be followed by a targeted phase I/II study in persons with advanced sarcoma. The Company is also planning a phase I study in sarcoma and lymphoma with a modified dosing schedule and a phase II study in pediatric sarcoma.

"With early indications of safety and activity in our phase I studies, we continue to progress confidently toward pivotal trials for both ZIO-101 and ZIO-201 in early 2007," said Dr. Lewis. "We estimate that the market potential of these two products together at peak year sales could approach $800 million, and we look forward to the challenge and rewards of being a publicly traded biopharmaceutical company."
