Sorrento Therapeutics merge with subsidiary of Quikbyte Software

Sorrento Therapeutics, Inc. ("STI"), a privately-held and development-stage biopharmaceutical company with a proprietary technology platform for the discovery and development of human therapeutic antibodies for the treatment of a variety of disease conditions, has merged with a wholly-owned subsidiary of QuikByte Software, Inc. (OTC Bulletin Board: QBSW), a publicly-traded company with no active operations. As a result of the merger, Sorrento has become a wholly-owned subsidiary of QuikByte. In connection with the consummation of the merger, QuikByte intends to change its name to "Sorrento Therapeutics, Inc." and redomesticate to a corporation incorporated under the laws of the State of Delaware. The combined company will be headquartered in San Diego, California.

Immediately prior to the closing of the merger, QuikByte completed a $2 million private placement of its common stock to certain investors, including affiliates of Dr. Phillip Frost, Chairman and Chief Executive Officer of OPKO Health, Inc. (NYSE Amex: OPK), which was a stockholder of STI prior to the merger, and an affiliate of Mr. Glenn L. Halpryn, a director of QuikByte and its Chairman, President and Chief Executive Officer prior to the merger, and Mr. Steven Jerry Glauser, a greater than 5% shareholder of QuikByte, President of the Glauser Group, Denver, Colorado and President and Managing Partner of Alex Rodriguez Mercedes Benz, Houston, Texas.

Upon the completion of the merger, after giving effect to the private placement, the QuikByte shareholders as of immediately prior to the private placement owned approximately 4.92% of the combined company, the investors in the private placement, some of whom were QuikByte or STI shareholders prior to the private placement, owned approximately 19.83% of the combined company, not including the shares of QuikByte which they owned prior to the private placement or which were issued to them in connection with the merger, and the former STI stockholders (including OPKO) owned approximately 75.25% of the combined company, in each case on a fully-diluted basis.

In connection with the merger, Dr. Antonius Schuh, who was the Chief Executive Officer of STI immediately prior to the merger, was appointed Chief Executive Officer of QuikByte, and Dr. Henry Ji, the inventor of the STI technology, who was the Chief Scientific Officer of STI prior to the merger, was appointed Chief Scientific Officer of QuikByte. Upon the merger, the board of directors of QuikByte was reconstituted to include four directors appointed by Dr. Schuh, who include Drs. Schuh and Ji, two directors appointed by OPKO and one director appointed by QuikByte.

Dr. Schuh commented, "Sorrento Therapeutics is excited to join with QuikByte, OPKO and Dr. Frost as we develop our proprietary platform technology for the generation of fully human monoclonal antibodies."

Mr. Glenn L. Halpryn, the Chairman, President and Chief Executive Officer of QuikByte prior to the merger stated, "We are pleased that QuikByte has this opportunity to enter into the growing field of human antibodies with an experienced team led by Drs. Schuh and Ji. The merger provides QuikByte shareholders with the opportunity to benefit from the experience of Sorrento's management and its proprietary technology as the Company develops its human antibody library." Mr. Halpryn will remain a director of QuikByte following the merger.
