LIPID SCIENCES, INC. REPORTS FINANCIAL RESULTS

FOR THE THIRD QUARTER 2007

In Vivo HDL Mimetic Peptide Data Presented By Dr. H. Bryan Brewer, Jr. at Two Major Scientific Conferences

Dr. S. Lewis Meyer to Present at the Acumen BioFin Rodman & Renshaw 9^th Annual Healthcare Conference in New York on November 7, 2007

PLEASANTON, Calif., November 5, 2007 — Lipid Sciences, Inc. (Nasdaq:LIPD) today reported financial results for the third quarter and nine months ended September 30, 2007. For the third quarter of 2007, the Company reported a net loss of $3.3 million, or $0.09 per share on a basic and diluted basis. This compares with a net loss of $2.9 million, or $0.10 per share, on a basic and diluted basis, for the same period in 2006. The financial results for the third quarter of 2007 include revenue of $106,000 related to the reimbursement of expenses pursuant to a collaborative research agreement with Elanco Animal Health, a division of Eli Lilly and Company, to develop immunological products for animal health.

Operating expenses for the third quarter reflected a 28% increase in research and development expense from the same period of the previous year. This increase is principally attributed to the initiation of a series of in vitro and in vivo studies supporting our HDL Mimetic Peptide development program.

For the nine months ending September 30, 2007, the Company reported a net loss of $8.5 million or $0.23 per share, on a basic and diluted basis. This compares with a net loss of $8.5 million or $0.30 per share on a basic and diluted basis, for the same nine-month period in 2006. The financial results for the nine months of 2007 include revenue of $302,000, related to the reimbursement of expenses pursuant to a collaborative research agreement with Elanco Animal Health.

Operating expenses for the first nine months ended September 30, 2007, increased by 5% to $9.4 million up from $8.9 million for the same period in the previous year. R&D expenses, which accounted for 69% of the Company’s operating expenses for the nine months ended September 30, 2007, increased 13% to $6.5 million from $5.7 million for the same period last year. The increase was primarily attributable to an increase in expenses associated with the initiation of a series of in vitro and in vivo studies for our HDL Mimetic Peptide program. Partially offsetting these increases was a decrease in expenses related to the clinical trial of our PDS-2 system. The clinical trial expenses, which included set-up, recruitment, and implementation costs, incurred in the first nine months of 2006 exceeded the ongoing recruitment and implementation costs incurred in the first nine months of 2007.

At September 30, 2007, the Company had approximately $9.2 million in cash and cash equivalents. The Company anticipates that sufficient capital is available to fund its operations, including current development projects, into the third quarter of 2008.

Dr. S. Lewis Meyer, President and Chief Executive Officer, commented, “HDL therapy clearly has a high profile in the cardiovascular disease marketplace where, despite spending $400 billion annually, once every 15 seconds someone is having a heart attack. We continue to demonstrate Lipid Sciences’ ability to be a key player in this space. Dr. H. Bryan Brewer, Jr., our Chief Scientific Director, recently presented the initial results of in vitro and in vivo HDL mimetic peptide studies at the XVI International Symposium on Drugs Affecting Lipid Metabolism (DALM 2007) in New York, and the International Atherosclerosis Society Workshop on HDL: Structure, Protective Functions and Therapeutic Applications in Santorini, Greece. The data presented demonstrate that our lead mimetic peptide candidate, LSI-518P, substantially increased HDL in a well-accepted animal model. Increased HDL will enhance the process of Reverse Cholesterol Transport—removing excess lipids from the arterial wall to reduce plaque build-up. Most significantly, this initial assessment of LSI-518P demonstrates that our lead candidate possesses the ability to remove cholesterol specifically from cholesterol-laden cells and reduce inflammation associated with atherosclerosis—properties similar to naturally-occurring ApoA-I. This makes LSI-518P an ideal HDL mimetic peptide.”

Dr. Meyer continued, “Within the next few months we expect to announce definitive results for important studies across our HDL Therapy and Viral Immunotherapy platforms. These studies include our comprehensive in vivo studies demonstrating the significant potential of our HDL mimetic peptide candidate; pre-clinical studies relating to the development of a therapeutic vaccine for HIV; and a ‘proof of concept’ study to develop a preventive vaccine for food animals as part of our agreement with Elanco. In early 2008 we also anticipate reporting results from our safety and feasibility HDL Selective Delipidation clinical trial being conducted in Washington, D.C. where we now have 26 out of 30 patients enrolled.”

Presentation at the Acumen BioFin Rodman & Renshaw 9^th Annual Healthcare Conference on

November 7, 2007: Dr. S. Lewis Meyer, President and Chief Executive Officer, will make a presentation at this global healthcare conference on Wednesday, November 7, 2007, at 10:50 a.m. (Eastern Time), at the New York Palace Hotel. Please log on to www.wsw.com/webcast/rrshq12/lipd to listen to a webcast of this presentation.

Lipid Sciences, Inc. is a development-stage biotechnology company engaged in the research and development of products and processes intended to treat major medical indications, in which lipids, or fat components, play a key role. The Company’s HDL Therapy platform (HDL Mimetic Peptides and HDL Selective Delipidation) aims to develop treatments to reverse atherosclerosis, a systemic disease of the blood vessels caused by the build-up of cholesterol-filled plaques in the vascular system and, most critically, in the coronary arteries. Regression of such plaques may have a major impact on reducing the risk of acute coronary events. The Company’s Viral Immunotherapy platform focuses on the removal of the lipid coatings from lipid-enveloped viruses and other lipid-containing infectious agents by applying Lipid Sciences’ proprietary delipidation technologies. The Company believes that removing the virus’ protective lipid coating enhances the processing and presentation of viral proteins to stimulate the body’s immune system to effectively fight the disease. Conditions that could potentially be impacted by these technologies include HIV, Hepatitis B and Hepatitis C, West Nile, SARS, influenza, and a broad range of animal health applications.
