--  Altairnano's RenaZorb, a phosphate binding drug candidate for humans,
    was licensed to Spectrum Pharmaceuticals.   Additional animal testing of
    the RenaZorb(TM) product was completed and analytical testing of the blood
    and urine samples has begun, which is expected to be completed in September
    2005.   Concurrently, Altair and Spectrum are continuing with their
    development work to prepare for a pre-IND meeting with the FDA.

--  The licensing of Renalan (similar chemistry to RenaZorb) as a
    potential drug for treatment of excess phosphate in dogs and cats with
    chronic renal failure is progressing with early-stage commercial
    discussions with potential partners.   Altairnano estimates that the
    potential market for phosphate limiting drugs for animals is estimated in
    excess of $100 million per year.

--  Altairnano continues with field trials and market introduction of
    NanoCheck™ making its first commercial shipment of NanoCheck during the
    quarter ended June 30. This shipment is being used by potential licensees
    or purchasers of NanoCheck for the current project phase, the summer field
    trials program, where NanoCheck is performing according to Altair's
    expectations in a significant number of consumer pools.    In preparation
    for an anticipated fourth quarter product launch, Altairnano is in contract
    negotiations with pool chemical companies that are major suppliers to the
    recreational water market of more than 10 million pools.

--  Altairnano is shipping advanced electrode battery nanomaterials to its
    development partner, Advanced Battery Technologies and is shipping
    development samples to other lithium ion battery manufacturers in North
    America, Europe and Asia.  Advanced Battery's Phase 1 - Product Research
    has completed testing of batteries utilizing Altairnano's battery
    electrode, which provided significantly improved recharging capability over
    traditional battery materials.   Additionally, Altairnano announced that it
    had received an order from Advanced Battery for 2,200 pounds (one metric
    ton) of Altairnano anode electrode nanomaterials for Phase 2 - Product
    Development.   These materials are intended to be used to construct
    developmental polymer lithium ion batteries designed to power one electric
    bus and one electric sedan. Additional information on Altairnano's battery
    materials program is provided in a separate release dated August 12, 2005.

--  Altairnano received a Phase ll grant of $476,850 from the National
    Science Foundation to develop battery cathode electrode nanomaterials to
    provide matched anode-cathode electrode materials for optimizing the
    electrochemical performance of lithium ion batteries.   These materials
    will form the basis for a second generation of battery electrode
    nanomaterials.

--  Altairnano has entered into an agreement with Western Oil Sands to
    provide pilot plant and office space within Altairnano's facilities for
    five employees and consultants of Western Oil Sands' to facilitate on-site
    collaboration between the two companies in furthering the engineering study
    of manufacturing TiO2 pigment from Western's tar sand tailings using
    Altairnano's AHP process.
