Deltagen Reports 2011 First Quarter Financial Results

Deltagen, Inc. (Pink Sheets:DGEN), a leading provider of drug discovery tools to the biopharmaceutical industry, today reported unaudited consolidated financial results for the three months ended March 31, 2011.

Revenues: The Company’s consolidated revenues for the three months ended March 31, 2011 totaled $0.266 million. The revenues in the first quarter were attributable primarily to license fees associated with the provision of knockout mice and related phenotypic data pursuant to orders placed by customers under the Company’s DeltaOne^TM program.

Expenses: Total consolidated expenses for the three months ended March 31, 2011 were $0.668 million. The expenses in the first quarter were attributable primarily to labor costs and other general and administrative expenses, together with $0.101 million in royalty and commission expenses.

Net Losses: Consolidated net losses before provision for income taxes for the three months ended March 31, 2011 were $0.402 million.

Cash, Cash Equivalents and Accounts Receivable: As of March 31, 2011, the Company had $2.353 million in consolidated cash and cash equivalents, compared to $3.530 million as of December 31, 2010, and had $0.155 million in accounts receivable. The decline in cash and cash equivalents was due to investment in the Company's Malvern, Pennsylvania facility and losses for the period. To date $2.675 million has been invested in the Malvern facility, not including tenant improvements, the cost of which will be amortized over the term of the facility lease. The Company will require additional capital by the fourth quarter of 2011 in order to fund its operations.

Major Events During Q1 2011 and Subsequent Events:

Deltagen BioServices: In May 2011, the name of the Company's wholly-owned subsidiary, Benten BioServices, Inc., was changed to Deltagen BioServices, Inc. ("Deltagen BioServices") in order to present a more consistent and familiar branding to our customers and investors. Deltagen BioServices completed installation of capital equipment in late January 2011 and was issued a temporary certificate of occupancy on February 7, 2011. Deltagen BioServices initiated in early March 2011 qualifications for the installed equipment. Following negotiations with the landlord of Deltagen BioServices' facility with respect to certain delays in its completion, the parties agreed to set the term commencement date of the lease as April 1, 2011 and the rent commencement date as October 1, 2011. Deltagen BioServices initiated commissioning and validation of the facility in late April 2011 and expects to commence commercial GMP-compliant operations in the first half of the third quarter of 2011. As of June 1, 2011, Deltagen BioServices had six full-time employees and one part-time employee.

Board of Directors: Deltagen BioServices' President and Chief Executive Officer, Ms. Paula MacDonald, was appointed to the Company's Board of Directors on April 29, 2011.

Management Changes: The Company's Chief Operating Officer, Dr. Winston Thomas, tendered his notice of resignation on June 3, 2011. Dr. Thomas will be employed by the Company until June 17, 2011, at which time his responsibilities will be assumed by the Company's CEO, Dr. Robert Driscoll.
