Exhibit 99.1

PHOENIX—(BW HealthWire)—Nov. 29, 2001—NZ Corporation (AMEX: NZ – news) and Lipid Sciences, Inc. today announced the closing of the previously announced merger of the two companies. The combined company will now be known as Lipid Sciences, Inc. Lipid Sciences has been approved for trading on Nasdaq NMS and will begin trading Friday, November 30, 2001 under the symbol LIPD, and will cease trading under the symbol NZ on the American Stock Exchange as of Thursday, November 29, 2001.

NZ Stockholders’ Potential Right to Receive Additional Shares

Each NZ stockholder as of the day immediately prior to the effective date of the merger may qualify to receive additional shares of Lipid Sciences common stock. To qualify to receive additional shares, an NZ stockholder must, within 60 days following the effective time of the merger, take action to become the direct registered owner of his, her or its shares of surviving corporation common stock. “Street name” holders will not be eligible to receive the right to purchase additional shares.

As soon as practicable following the 60th day following the merger, Lipid will issue to each NZ stockholder who has perfected the right to receive additional shares, certificates evidencing one right for each share of NZ common stock held by that stockholder. The rights will not be transferable or assignable, and the registered holder of such rights will forfeit the number of rights equal to the number of shares of NZ common stock sold or otherwise transferred by such holder during the two-year holding period after the merger. Any right that is forfeited as a result of a transfer of the stock relating to that right during the holding period will be worthless.

Additional shares of Lipid Sciences common stock issued to rights holders will be issued following the holding period, if, during the holding period, (i) the average closing price per share of surviving corporation common stock over any 20 consecutive trading days does not equal or exceed $12.00 per share, or (ii) the total volume of the shares of surviving corporation common stock during such 20-day period does not equal or exceed 1,500,000 shares.

Additional information concerning the rights is available in the Prospectus/Proxy Statement relating to the Merger filed with the SEC on November 9, 2001, or from the Company, upon request.
